The butt welding of the seamless steel pipes is widely applied to steel structure engineering projects such as pipe trusses, net racks, comprehensive pipe racks and the like as a common pipe connecting mode. In steel construction engineering, some of the main pipe fittings may be assembled in a factory and then transported to a construction site for installation. However, in the actual construction process, part of the pipe fittings are limited by conditions and the butt welding operation of the pipe fittings is required to be carried out on site. Because of a plurality of field operation influencing factors and high operation difficulty (especially high-altitude butt welding operation difficulty is high), weld plumpness, pipe fitting butt joint precision and the like are difficult to control accurately, butt welding quality of the pipe fitting is difficult to guarantee and unstable, unqualified butt welding is easy to occur, tensile strength, bending strength and shear strength at a butt welding position are seriously influenced, and potential safety hazards are buried for use of steel structure engineering. And for the pipe fittings which are subjected to butt welding operation but are unqualified in butt welding, the replacement difficulty is obviously high, the construction period is delayed, and the cost is increased.

Therefore, the embodiment of the application provides a reinforcing structure, which can strengthen the butt welding part between two pipe fittings which finish butt welding operation so as to strengthen the tensile strength, the bending strength and the shearing strength of the butt welding part, thereby improving the connection effect and the connection strength between the two pipe fittings, promoting the connection between the two pipe fittings to meet the requirements, being particularly suitable for promoting the strength of the butt welding part with unqualified butt welding to meet the requirements, further omitting the replacement operation of the unqualified pipe fittings with unqualified butt welding, and being beneficial to shortening the construction period and reducing the cost.

The following detailed description of specific implementations of the present application refers to specific embodiments:

referring to fig. 1, 2 and 3, some embodiments of the present application provide a reinforcing structure 10 for reinforcing a butt welding portion 21 between two pipes 20 that have completed a butt welding operation, which may be applicable to, but not limited to, butt welding of pipes 20 in steel structural engineering such as pipe trusses, net racks, composite pipe racks, and the like. Wherein the two pipes 20 may be butt welded in a construction site or other scene. The butt-welded portion 21 is a butt-welded portion between the two pipes 20, and the butt-welded portion 21 includes a butt-welded seam 211 and a vicinity of the butt-welded seam 211. Wherein the pipe 20 may be, but is not limited to, a steel pipe, etc., and the pipe 20 may be, but is not limited to, a round pipe, a square pipe, etc.

In this embodiment, the reinforcing structure 10 includes at least two reinforcing members 11. The respective reinforcing members 11 are disposed in order along the circumferential direction a of the butt-welded portion 21, and collectively sandwich the butt-welded portion 21 therebetween. Each reinforcement 11 is fixedly connected to the outer peripheral surface of the butt welded portion 21.

It should be noted that the reinforcing members 11 are provided in at least two, and thus, it is possible to facilitate flexible mounting of each reinforcing member 11 to the outer peripheral side of the butt-welded portion 21, respectively, without penetrating and moving the reinforcing structure 10 from the free end of the pipe member 20 away from the butt-welded portion 21 to the butt-welded portion 21, thereby improving the convenience of assembly and the assembly efficiency of the reinforcing structure 10 and the butt-welded portion 21.

The circumferential direction a of the butt-welded portion 21, that is, the circumferential direction of the outer peripheral surface of the butt-welded portion 21. The respective reinforcing members 11 are disposed in this order along the circumferential direction a of the butt welded portion 21, the shape of the ring surrounded by the respective reinforcing members 11 is similar to the shape of the outer peripheral surface of the butt welded portion 21, at least part of the inner wall of the respective reinforcing members 11 abuts against the outer peripheral surface of the butt welded portion 21, and the respective reinforcing members 11 sandwich the butt welded portion 21 together. The two reinforcements 11 adjacent to each other in the circumferential direction a of the butt welded portion 21 may be provided at a distance from each other or may be provided in contact with each other. The reinforcing members 11 may have the same structure (i.e., the same shape, size, material, etc.), or may have different structures (i.e., different shapes, sizes, materials, etc.). The length, width, thickness, etc. of the reinforcement 11 may be flexibly set as required, and in particular, may be set according to a formula or specification.

In the case where the respective reinforcing members 11 sandwich the butt welded portion 21 in common, the respective reinforcing members 11 may be fixedly connected to the outer peripheral surface of the butt welded portion 21 by, but not limited to, welding, bonding, or the like. By this arrangement, each reinforcement 11 can be stably positioned with respect to the butt welded portion 21, and the state in which each reinforcement 11 holds the butt welded portion 21 together can be facilitated, so that the reinforcement of the butt welded portion 21 for which the butt welding operation has been completed can be caused to be permanently and reliably achieved by each reinforcement 11.

In summary, in the reinforcing structure 10 provided in the embodiment of the present application, at least two reinforcing members 11 are disposed on the peripheral side of the butt welding portion 21, and each reinforcing member 11 is fixedly connected to the outer peripheral surface of the butt welding portion 21, so that each reinforcing member 11 can permanently and reliably clamp the butt welding portion 21 together, thereby reinforcing the butt welding portion 21 where the butt welding operation is completed. Based on this, the bearing capacity, tensile strength, bending strength, and shear strength of the butt welded portion 21 can be effectively enhanced, so that the connection effect, connection strength, and overall structural reliability between the two pipe members 20 can be improved, and the connection between the two pipe members 20 can be promoted to meet the requirements. The embodiment is particularly suitable for reinforcing the butt welding portion 21 of the pipe fitting 20 which has completed the butt welding operation but is unqualified in butt welding, so that the strength of the unqualified butt welding portion 21 is promoted to meet the requirement, the replacement operation of the unqualified pipe fitting 20 can be omitted, the construction period can be shortened, and the cost can be reduced.

Referring to fig. 1, 2 and 3, in some embodiments of the present application, the inner wall of the reinforcement 11 is abutted against the outer peripheral surface of the butt-welded portion 21. Wherein the inner wall of the reinforcement 11, i.e., the wall surface of the reinforcement 11 facing the outer circumferential surface of the butt-welded portion 21.

Through adopting above-mentioned scheme, through making the inner wall laminating butt weld portion 21 of reinforcement 11's outer peripheral face, can make the area of contact of reinforcement 11 and butt weld portion 21 increase to can improve the connection tightness and the connection reliability between reinforcement 11 and the butt weld portion 21, can strengthen the support effect and the reinforcement effect of reinforcement 11 to butt weld portion 21, can improve the reliability and the stability of the overall structure of reinforcement 11 and butt weld portion 21, can reduce the reinforcement 11 and take place the risk of becoming flexible and vibrating for butt weld portion 21.

Of course, in other embodiments, it is permissible that the inner wall of the reinforcing member 11 does not come into perfect abutting contact with the outer peripheral surface of the butt welded portion 21 due to construction errors.

Referring to fig. 1 and 2, in some embodiments of the present application, the reinforcing member 11 is welded to the outer peripheral surface of the butt-welded portion 21 on opposite sides in the axial direction b of the butt-welded portion 21.

The axial direction b of the butt welded portion 21, that is, the extending direction of the central axis of the butt welded portion 21. The reinforcing member 11 is provided on opposite sides in the axial direction b of the butt-welded portion 21, that is, on both long-side sides of the reinforcing member 11 extending in the circumferential direction a of the butt-welded portion 21. The reinforcing members 11 are fixedly connected to the outer peripheral surface of the butt welded portion 21 by welding on opposite sides in the axial direction b of the butt welded portion 21, and each produce a reinforcing weld 111. The dimensions of the width, height, length, etc. of the reinforcement weld 111 may be flexibly set as required, and in particular may be set according to a formula or specification. Wherein the welding can adopt, but not limited to, full-bead welding.

By adopting the above-described arrangement, the reinforcement 11 can be easily and quickly joined to the outer peripheral surface of the butt-welded portion 21 by welding, on the opposite sides in the axial direction b of the butt-welded portion 21. Based on this, the reinforcement 11 can be made to form the longer reinforcing weld 111 with the butt-welded portion 21 along the both long sides of the axial direction b of the butt-welded portion 21, so that the fixing effect between the reinforcement 11 and the butt-welded portion 21 can be secured and enhanced, the risk of the reinforcement 11 being deformed and displaced axially with respect to the butt-welded portion 21 can be reduced, and the reliability and stability of the overall structure of the reinforcement 11 and the butt-welded portion 21 can be improved. And, the reinforcement 11 can be caused to provide sufficient support and reinforcement to the butt weld 21 on opposite sides thereof in the axial direction b of the butt weld 21, so that the flexural strength and shear strength of the butt weld 21 can be effectively enhanced, and the strength of the butt weld 21 can be caused to meet the requirements.

Of course, in other embodiments, the opposite sides of the reinforcement 11 along the axial direction b of the butt-welded portion 21 may be fixedly connected (e.g., adhered) to the outer peripheral surface of the butt-welded portion 21 by other fixing means.

Referring to fig. 1, 2 and 3, in some embodiments of the present application, a welding gap 12 is formed between at least two adjacent reinforcing members 11 along a circumferential direction a of the butt welded portion 21. The side of the reinforcement 11 corresponding to the welding gap 12 is welded to the outer peripheral surface of the butt welded portion 21.

The at least one group of adjacent two reinforcing members 11 are arranged at intervals along the circumferential direction a of the butt welded portion 21, and the interval spaces may form the welding gaps 12. The welding gap 12 may be formed by being spaced between each adjacent two of the reinforcing members 11, or the welding gap 12 may be formed by being spaced between part of the adjacent two of the reinforcing members 11. In the case of the individual reinforcing members 11, the welding gap 12 may be formed in one side of the reinforcing members 11 in the circumferential direction a of the butt welding portion 21, the welding gap 12 may be formed in both of the opposite sides of the reinforcing members 11 in the circumferential direction a of the butt welding portion 21, or the welding gap 12 may not be formed in both of the opposite sides of the reinforcing members 11 in the circumferential direction a of the butt welding portion 21 (in the case where the reinforcing structure 10 has at least one welding gap 12).

The welding gap 12 may serve as a welding operation space for an operator to perform a welding operation on the corresponding side of the reinforcing member 11 in the welding gap 12. That is, the operator can weld the side of the reinforcing member 11 corresponding to the welding gap 12 with the outer peripheral surface of the butt welded portion 21 in the welding gap 12. The side of the reinforcement 11 corresponding to the welding gap 12 is the side of the reinforcement 11 participating in forming the welding gap 12.

By adopting the above-described arrangement, by disposing at least one group of adjacent two reinforcing members 11 at intervals in the circumferential direction a of the butt welding portion 21, it is possible to facilitate formation of the welding gap 12 via the interval space, and it is possible to facilitate welding, in the welding gap 12, the side of the reinforcing member 11 corresponding to the welding gap 12 with the outer peripheral surface of the butt welding portion 21. Based on this, at least part of the short side of the reinforcing member 11 in the circumferential direction a of the butt welded portion 21 can be firmly joined to the outer peripheral surface of the butt welded portion 21, and the reinforcing weld 111 can be formed. Thus, the fixing effect of the portion of the reinforcing member 11 to the butt weld portion 21 can be enhanced, the risk of circumferential deformation and circumferential displacement of the portion of the reinforcing member 11 relative to the butt weld portion 21 can be reduced, and the structural reliability and structural stability of the entire portion of the reinforcing member 11 and the butt weld portion 21 can be improved. And, the portion of the reinforcing member 11 can be caused to provide support and reinforcement to the butt weld 21 at the side thereof in the circumferential direction a of the butt weld 21, so that the lateral load-carrying capacity, the bending strength and the torsional strength of the butt weld 21 can be enhanced, and the strength of the butt weld 21 can be caused to meet the requirements.

This embodiment is particularly suitable for use in conjunction with the "two opposite sides of the reinforcing member 11 in the axial direction b of the butt-welded portion 21 are welded to the outer peripheral surface of the butt-welded portion 21" embodiment, so that at least a portion of the continuous plurality of side sides of the reinforcing member 11 can be welded to the butt-welded portion 21 and a continuous, long reinforcing weld 111 can be formed, whereby the fixing effect of this portion of the reinforcing member 11 to the butt-welded portion 21 can be enhanced, and the joining operation is convenient and quick.

Of course, in other embodiments, the reinforcement 11 may be fixedly attached to the outer peripheral surface of the butt-welded portion 21 along the side of the circumferential direction a of the butt-welded portion 21 in other manners (e.g., adhesion, etc.). Alternatively, the side of the reinforcing member 11 in the circumferential direction a of the butt-welded portion 21 may be connected instead to the adjacent reinforcing member 11 (the connection manner is not limited, and for example, the reinforcing lugs 112 and the fasteners 13 described below may be employed) while being fixed with respect to the butt-welded portion 21.

Referring to fig. 1, 2 and 3, in some embodiments of the present application, at least one reinforcing member 11 is welded to the outer peripheral surface of the butt-welded portion 21 along opposite sides of the circumferential direction a of the butt-welded portion 21.

By adopting the above-described arrangement, at least one reinforcing member 11 can be welded to the outer peripheral surface of the butt-welded portion 21 by making opposite sides thereof in the circumferential direction a of the butt-welded portion 21 so that both short side sides thereof in the circumferential direction a of the butt-welded portion 21 form the reinforcing weld 111 with the butt-welded portion 21. Based on this, the fixing effect of the reinforcing member 11 and the butt-welded portion 21 can be enhanced, the risk of occurrence of circumferential deformation and circumferential displacement of the reinforcing member 11 with respect to the butt-welded portion 21 can be reduced, and the structural reliability and structural stability of the entire reinforcing member 11 and the butt-welded portion 21 can be improved. And, the reinforcing member 11 is caused to be able to provide support and reinforcement to the butt-welded portion 21 on both of its opposite sides in the circumferential direction a of the butt-welded portion 21, so that the lateral load-carrying capacity, bending strength and torsional strength of the butt-welded portion 21 can be enhanced, and the strength of the butt-welded portion 21 can be caused to meet the requirements.

This embodiment is particularly suitable for use in conjunction with the embodiment of "the opposite sides of the reinforcing member 11 in the axial direction b of the butt-welded portion 21 are both welded to the outer peripheral surface of the butt-welded portion 21", so that the peripheral edge of the reinforcing member 11 is welded to the butt-welded portion 21 and forms a continuous reinforcing bead 111, whereby the stress concentration of the reinforcing bead 111 can be reduced, the risk of occurrence of cracks and deformation of the reinforcing bead 111 can be reduced, the fixing effect, the connection tightness and the connection reliability of the reinforcing member 11 to the butt-welded portion 21 can be improved to a greater extent, and the connection operation is convenient and quick.

Of course, in other embodiments, along the circumferential direction a of the butt-welded portion 21, only one side of the reinforcement 11 may be welded to the outer peripheral surface of the butt-welded portion 21, or neither side may be welded to the outer peripheral surface of the butt-welded portion 21. For example, along the circumferential direction a of the butt welded portion 21, the reinforcing member 11 may be welded to the outer peripheral surface of the butt welded portion 21 on only one side, while the other side is connected to the adjacent reinforcing member 11 (the connection manner is not limited, and for example, the following reinforcing lugs 112 and fasteners 13 may be employed).

Referring to fig. 1, 2 and 3, in some embodiments of the present application, the dimension d of the welding gap 12 along the circumferential direction a of the butt welding portion 21 is greater than 0 and less than or equal to one tenth of the circumference of the ring surrounded by each stiffener 11.

The shape of the ring surrounded by each reinforcement 11 is similar to the shape of the outer peripheral surface of the butt welded portion 21, and may be a circular ring, a polygonal ring, or the like. The welding gap 12 is along the dimension d of the circumferential direction a of the welded portion 21, i.e., a part of the circumference of the ring surrounded by the respective reinforcing members 11. In some embodiments, the ring defined by each stiffener 11 is a circular ring, and the weld gap 12 has an arc length along the dimension d of the circumferential direction a of the weld 21.

By adopting the above-described arrangement, by making the dimension d of the welding gap 12 in the circumferential direction a of the butt welding portion 21 larger than 0 and smaller than or equal to one tenth of the circumference of the ring surrounded by each reinforcing member 11, on the one hand, it is ensured that the welding gap 12 can provide a sufficient welding operation space for the entry and exit of the welding tool and the welding material, and the filling of the welding material, so that the welding operation of the side of the reinforcing member 11 corresponding to the welding gap 12 with the butt welding portion 21 can be facilitated. On the other hand, the dimension occupation of the compressible welding gap 12 in the circumferential direction a of the butt welded portion 21 is made to secure the sufficient extension dimension of the reinforcing member 11 in the circumferential direction a of the butt welded portion 21, so that the reinforcing effect of the reinforcing member 11 on the butt welded portion 21 can be secured and enhanced.

Referring to fig. 4, in some embodiments of the present application, at least one pair of two reinforcing members 11 adjacent in the circumferential direction a of the butt welded portion 21, a reinforcing lug 112 is provided on a side of the two reinforcing members 11 facing each other, and the reinforcing lugs 112 of the two reinforcing members 11 are disposed opposite to each other and connected by a fastener 13.

In the circumferential direction a of the butt welded portion 21, reinforcing lugs 112 are provided between at least one pair of adjacent reinforcing members 11, respectively, toward each other, and the reinforcing lugs 112 of the two reinforcing members 11 are disposed opposite to each other and connected by fasteners 13. Wherein the fastener 13 may be, but is not limited to, a bolt, rivet, pin, or the like.

The two adjacent stiffeners 11 may be connected to each other via the reinforcing lugs 112 and the fasteners 13, or the two adjacent stiffeners 11 may be partially connected to each other via the reinforcing lugs 112 and the fasteners 13. For the individual reinforcing member 11, the reinforcing member 11 may be provided with the reinforcing lugs 112 along one side of the circumferential direction a of the butt-welded portion 21, the reinforcing lugs 112 may be provided on both opposite sides of the reinforcing member 11 along the circumferential direction a of the butt-welded portion 21, or the reinforcing lugs 112 may not be provided on both opposite sides of the reinforcing member 11 along the circumferential direction a of the butt-welded portion 21 (in the case where the reinforcing structure 10 has at least one reinforcing lug 112).

By adopting the above-described arrangement, by arranging the reinforcing lugs 112 toward each other between at least one group of adjacent two reinforcing members 11, respectively, in the circumferential direction a of the butt welded portion 21, it is possible to facilitate connection of the reinforcing lugs 112 of two reinforcing members 11 via the fastener 13, so that the adjacent two reinforcing members 11 are firmly connected to each other. Based on this, the state of mutually stably-connected adjacent two reinforcing members 11, which are in mutually stable positions and mutually stably and jointly clamp the butt welded portion 21, can be made to be mutually stable, so that the connection stability and connection reliability between the adjacent two reinforcing members 11 can be improved, the clamping effect, supporting effect and reinforcing effect of the whole of this portion of reinforcing members 11 on the butt welded portion 21 can be optimized, the risk of loosening or displacement of this portion of reinforcing members 11 during the exertion of utility can be reduced, so that the transverse load-carrying capacity, bending strength and torsional strength of the butt welded portion 21 can be enhanced, and the strength of the butt welded portion 21 can be promoted to meet the requirements.

Referring to fig. 2 together, the present embodiment is particularly suitable for use in combination with the embodiment of "the opposite sides of the reinforcement 11 in the axial direction b of the butt-welded portion 21 are both welded to the outer peripheral surface of the butt-welded portion 21", such that the side of the reinforcement 11 in the axial direction b of the butt-welded portion 21 can be directly fixedly connected to the butt-welded portion 21, while the side of the reinforcement 11 in the circumferential direction a of the butt-welded portion 21 can be connected to the adjacent reinforcement 11 to clamp the butt-welded portion 21, thereby adjusting and optimizing the clamping, supporting and reinforcing effects of the reinforcement 11 to the butt-welded portion 21.

Of course, in other embodiments, the reinforcement 11 may be connected to the adjacent reinforcement 11 along the side of the circumferential direction a of the butt welded portion 21 in other manners (e.g., welded, bonded, etc.). Alternatively, the side of the reinforcing member 11 in the circumferential direction a of the butt-welded portion 21 may instead be fixedly joined to the outer surface of the butt-welded portion 21.

Referring to fig. 4, in some embodiments of the present application, at least one reinforcing member 11 is provided with reinforcing lugs 112 on opposite sides of the butt-welded portion 21 in the circumferential direction a.

By adopting the above-described arrangement, at least one reinforcing member 11 can be connected to the corresponding adjacent reinforcing member 11 via the reinforcing lugs 112 and the fastener 13 by making it possible to firmly connect with the adjacent reinforcing member 11 on the opposite sides thereof in the circumferential direction a of the butt welded portion 21. Based on this, the connection stability and connection reliability between the reinforcement 11 and the adjacent reinforcement 11 can be enhanced, the relative position and the relative state between the reinforcement 11 and the adjacent reinforcement 11 can be stabilized, the reinforcement 11 and the adjacent reinforcement 11 can be facilitated to clamp the butt-welded portion 21 together, the clamping effect, the supporting effect and the reinforcing effect of the reinforcement 11 and the adjacent reinforcement 11 on the butt-welded portion 21 can be optimized, and thus the transverse carrying capacity, the bending strength and the torsional strength of the butt-welded portion 21 can be enhanced, and the strength of the butt-welded portion 21 can be promoted to meet the requirements.

Referring to fig. 2 together, the present embodiment is particularly suitable for use in combination with the embodiment of welding the opposite sides of the reinforcement 11 along the axial direction b of the butt-welded portion 21 to the outer peripheral surface of the butt-welded portion 21, so that the opposite sides of the reinforcement 11 along the circumferential direction a of the butt-welded portion 21 can be firmly connected to the corresponding adjacent reinforcement 11, and the opposite sides of the reinforcement 11 along the axial direction b of the butt-welded portion 21 can be directly and fixedly connected to the butt-welded portion 21, thereby greatly improving the fixing effect, connection tightness and connection reliability of the reinforcement 11 and the butt-welded portion 21, and optimizing the clamping, supporting and reinforcing effects of the reinforcement 11 on the butt-welded portion 21.

Of course, in other embodiments, along the circumferential direction a of the butt welded portion 21, only one side of the reinforcement 11 may be connected to the adjacent reinforcement 11 via the reinforcing lugs 112 and the fasteners 13, or neither side may be directly connected to the adjacent reinforcement 11. For example, along the circumferential direction a of the butt weld 21, the reinforcing member 11 may be connected to the adjacent reinforcing member 11 via the reinforcing lugs 112 and the fasteners 13 on only one side, while the other side is connected to the adjacent reinforcing member 11 in other ways or fixedly connected to the outer surface of the butt weld 21.

Based on this, the gap between the adjacent two reinforcing members 11 connected via the reinforcing lugs 112 and the fastener 13 can be compressed, the extension dimension of the reinforcing members 11 in the circumferential direction a of the butt-welded portion 21 can be enlarged, and the contact area of the reinforcing members 11 with the butt-welded portion 21 can be increased; also, since the adjacent two reinforcing members 11 abut against each other, the risk of vibration or displacement of this portion of the reinforcing member 11 during the period of utility can be reduced. The reinforcing member 11 thus improves the supporting and reinforcing effects of the butt weld 21, and enhances the load-bearing capacity, bending strength, and torsional strength of the butt weld 21.

Of course, in other embodiments, adjacent two reinforcements 11 connected via the reinforcing ears 112 and fasteners 13 may be left with a slight gap as desired.

For example, the pipe 20 is a steel pipe, and the reinforcing member 11 is a steel structural member.

By adopting the above-mentioned scheme, by making the material of the reinforcement 11 the same as that of the pipe 20, on the one hand, the supporting effect and the reinforcing effect of the reinforcement 11 on the butt welded portion 21 can be ensured, and the bearing capacity, tensile strength, bending strength and shear strength of the butt welded portion 21 can be ensured and enhanced. On the one hand, the reinforcing member 11 and the pipe member 20 can be made uniform in material, so that the risk of corrosion or the like caused between different materials can be reduced. On the one hand, the reinforcing member 11 and the pipe 20 of the same material are more easily connected by welding or the like, so that the connection convenience and the connection quality between the reinforcing member 11 and the butt welded portion 21 can be improved. On the one hand, the reinforcing member 11 and the pipe 20 of the same material are more matched in terms of performance, durability and the like, so that the overall service lives of the reinforcing member 11 and the pipe 20 can be prolonged.

Of course, in other embodiments, the material of the stiffener 11 may be different from the material of the tube 20.

In addition, the symmetrical arrangement can also correspondingly improve the overall aesthetic appearance of the two reinforcing members 11 and the butt welded portion 21.
