Description

Background
The steam conduit carrying structure may be a general term for a bridge or any other cable channel like equipment. When wind load acts on the side surface of the bearing structure, the bearing structure can swing along with wind on the static force effect, the pipeline size and the bearing structure are coupled on the dynamic effect, the bearing structure can generate displacement far larger than that under the static force effect, unbalanced force of the wind load is needed to be counteracted by the wind resistance main rope, and stability of the bearing structure is guaranteed, so that firmness of structural design of the wind resistance main rope is crucial.
The structural design adopted by the wind-resistant main cable of the existing pipeline suspension cable through equipment is that a section of longer steel structure cantilever extends outwards symmetrically on two lateral sides of a tower column, the wind-resistant main cable has larger sagittal ratio and transverse inclination angle, and a steering device is arranged on the steel structure cantilever to anchor the wind-resistant main cable on a wind cable anchorage which is poured in advance. The disadvantages of this approach are:
1) The steam pipeline has strict requirements on structural deformation, the deformation of the bearing structure under the action of wind force can exceed a standard allowable value due to insufficient constraint capacity of the wind-resistant inhaul cable of the pipeline suspension cable passing equipment, the bearing structure can be greatly deformed in the transverse direction, dislocation of the steam pipeline is caused, the steam pipeline can be damaged at the dislocation position, and serious potential safety hazards are generated.
2) Because the wind-resistant main cable force is larger, the steering device bears larger force, the force is transmitted to the steel structure cantilever, so that the steel structure cantilever is larger in deformation, the wind-resistant main cable tension loss is more, the constraint capacity of the bearing structure is reduced, and the safety of the wind-resistant main cable is lower due to the coupling power action of wind.

Detailed Description
The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
Referring to fig. 1 to 10, the following embodiments of the present invention are provided:
as shown in fig. 1 to 10, a first embodiment of the present invention provides a pull-up structure for steam pipe laying, at least comprising:
a load-bearing structure 1, said load-bearing structure 1 forming a laying area 101 along a laying path of a steam duct 2;
a connection structure 3, at least in the length direction of the bearing structure 1, wherein the connection structure 3 is connected with two ends of the bearing structure 1;
a pair of pull assemblies 4, at least in the width direction of the bearing structure 1, wherein the pair of pull assemblies 4 are arranged at two sides of the bearing structure 1;
wherein the pull-up assembly 4 provides at least a first force F1 and a second force F2 on the load bearing structure 1;
the direction of the first acting force F1 is perpendicular to the length direction of the bearing structure 1;
the direction of the second acting force F2 is perpendicular to the length direction of the bearing structure 1, and the direction of the first acting force F1 is opposite to the direction of the second acting force F2;
wherein, the pair of pull assemblies 4 at least have:
a parameter a representing a first vector;
a parameter B representing a second vector;
and a parameter C representing the length of the load-bearing structure 1;
wherein the first vector is the maximum height of the pull-to-pull assembly 4 along the height direction of the carrying structure 1;
wherein the second vector is the minimum width of the pull-to-pull assembly 4 along the width direction of the carrying structure 1;
the value range of A/C is: 0.1 to 0.5;
and, the value range of B/C is: 0.1 to 0.3.
In this embodiment, the load-bearing structure 1 may be a general term for a bridge or any other cable channel type equipment. The load-bearing area formed thereby can be used for the laying of the steam lines 2, for example a bridge deck as the laying area 101 of the steam lines 2.
On the basis of the above, a connecting structure 3 and a counter pull assembly 4 are added.
For the connection structure 3, it is used to provide a pulling force in a direction perpendicular to the load-bearing structure 1 to ensure a stable force of the load-bearing structure 1 in this direction. Specifically, in the length direction of the bearing structure 1, the connection structure 3 and the bearing structure 1 form connection points at a plurality of positions, and the connection structure 3 can provide the aforesaid tension for the bearing structure 1 at the connection points, so that the tension is ensured to be in accordance with the gravity of the bearing structure 1 and the steam pipeline 2 laid thereon by the structure of the distributed load, and further the problem that the tension is concentrated or the tension is lost at a certain position of the bearing structure 1 is avoided.
For the pull-up assembly 4, it is used to provide wind resistance to the load bearing structure 1. In the prior art, wind-resistant cables are usually arranged on both sides of the load-bearing structure 1 to achieve wind resistance, but it has been found that:
first, the first vector of the anti-wind cable is too large, thereby increasing its threshold value in response to the wind load of the load bearing structure 1. In particular, the wind-resistant cable only works when the load-bearing structure 1 is subjected to a large wind load, i.e. its offset in the width direction is large. However, the laying process of the steam pipe 2 requires a strict amount of deviation from the load bearing structure 1, and if the deviation is too large, the radial distortion of the steam pipe 2 increases, which results in breakage.
Secondly, the second vector of the wind-resistant cable is too large, so that it cannot cope with wind loads according to the structural characteristics of the load-bearing structure 1. In particular, the structural characteristics mean that, due to the existence of the connection foundation (e.g. bridge pier) at the two ends of the bearing structure 1, the position is relatively less affected by the wind load, while the middle part of the bearing structure 1 is usually in a suspended state, so that the position is relatively more affected by the wind load and is very liable to generate a large deflection. And the second amount is too large, which can lead to the fact that the acting force of the wind-resistant inhaul cable on the middle part of the bearing structure 1 is consistent with the acting force on the two ends of the wind-resistant inhaul cable, so that the wind-resistant requirement of the middle part cannot be met.
Based on this, the first and second amounts of the pair of pull members 4 and the second amounts of the pair of pull members 4 are defined (i.e., the parameters are defined as described above). Wherein, the first vector is the maximum height of the opposite-pulling assembly 4 along the height direction of the bearing structure 1, and the second vector is the maximum width of the opposite-pulling assembly 4 along the width direction of the bearing structure 1.
Within this range it was found that:
firstly, the maximum height is the height of the horizontal connecting line between the central position of the middle section of the bearing structure 1 and the two ends of the opposite-pulling assembly 4, namely, the first vector is a specific parameter of the opposite-pulling assembly 4 in the middle section, the smaller the ratio of the parameter to the length L of the opposite-pulling assembly 4 is, the larger the acting force on the middle section is, namely, the stronger the acting force F1 (the pulling force provided by the opposite-pulling assembly 4 positioned on one side of the bearing structure 1) or the second acting force F2 (the pulling force provided by the opposite-pulling assembly 4 positioned on the other side of the bearing structure 1) of the middle section is, so that the constraint requirement that the middle section is subjected to larger wind load deflection can be met;
secondly, the minimum width is the width of the middle section of the bearing structure 1 and the width of the side edge of the bearing structure 1, i.e. the second vector is a specific parameter of the opposite-pulling assembly 4 in the middle section. Similarly, the smaller the ratio of the parameter to the length L of the opposite-pulling component 4, the larger the acting force acting on the middle section, that is, the stronger the middle section receives the first acting force F1 (the pulling force provided by the opposite-pulling component 4 on one side of the bearing structure 1) or the second acting force F2 (the pulling force provided by the opposite-pulling component 4 on the other side of the bearing structure 1) of the opposite-pulling component 4, so that the constraint requirement that the middle section receives a larger wind load offset can be met.
As shown in fig. 1 to 7, a second embodiment of the present invention proposes a pull-up structure for steam pipe laying, and the connection structure 3 includes at least, on the basis of the first embodiment:
a connection tower 301 and a connection assembly 302;
both ends of the connecting component 302 are connected with the connecting tower column 301;
and, the connection assembly 302 forms a plurality of groups of connection points with at least the bearing structure 1, and each group of connection points at least includes:
a main suspension point 501 on the connection assembly 302, and two auxiliary suspension points 502 on the bearing structure 1;
and, in the direction perpendicular to the bearing structure 1, the main hanging point 501 and the auxiliary hanging point 502 have triangular structures.
In the present embodiment, the connection structure 3 is specifically defined.
The connecting structure 3 is composed of a connecting tower 301 and a connecting assembly 302.
Moreover, the connection assembly 302 specifically includes: a main cable 3021 and a first boom 3022;
wherein the main cable 3021 spans the load bearing structure 1 and is connected to the connection tower 301;
wherein, one end of the first boom 3022 is connected to the main cable 3021, and the other end is connected to the carrying structure 1;
the connection position between the first boom 3022 and the main cable 3021 constitutes the main boom point 501;
and, the connection position of the first boom 3022 and the bearing structure 1 constitutes the secondary suspension point 502.
In the prior art, there are typically two main cables 3021 and they are arranged along the length of the carrying structure 1, and the first boom 3022 is connected between the main cable 3021 and the carrying structure 1. The structure is as follows:
the main cable 3021 is deflected when subjected to wind load, which causes it to fail to provide a good restraining effect on the carrying structure 1, thereby causing the deflection of the carrying structure 1 to further increase.
The first boom 3022 is arranged perpendicular to the load bearing structure 1 and is only capable of providing an upward pulling force on the load bearing structure 1, and is not capable of providing a relatively large restraining force in the width direction of the load bearing structure 1, whereas the wind load mainly affects the load bearing structure 1 in this direction, so that the first boom 3022 is difficult to exert the restraining effect.
Based on this, in this embodiment, one main hanging point 501 and two auxiliary hanging points 502 are provided, and the three form a triangle structure. The purpose of this configuration is to increase the correlation between the first booms 3022 to provide a relatively large restraining force for the load bearing structure 1. Specifically, two ends of the main cable 3021 are connected to the connection tower 301 and the number of the first booms 3022 is 1, one end of each of the first booms 3022 is connected to the main cable 3021 to form a main suspension point location 501, and the other end thereof is connected to the load bearing structure 1 to form a sub suspension point location 502. When the three hanging point positions form a triangle structure, the following steps are found:
first, a plurality of first suspenders 3022 are commonly connected to the same main cable 3021, so that the main cable 3021 is prevented from being greatly deviated, and the bearing structure 1 is prevented from being affected;
secondly, the plurality of first suspension rods 3022 can provide a relatively large restraining force for the bearing structure 1 to assist the opposite-pulling assembly 4, so as to provide a tensile force for resisting wind load for the bearing structure 1, and avoid an excessive offset of the bearing structure 1.
On the basis of the above, the connection tower 301 is defined. The connecting tower 301 includes at least a first connecting body 3011, a second connecting body 3012, a third connecting body 3013, and a carrying body 3014. The first connecting body 3011 is a building foundation, and is used for being connected to a construction site (such as the ground), the second body is in a diamond structure, and is integrally formed with the first connecting body 3011, the third connecting body 3013 is integrally formed with the second body, and is connected with the main cable 3021. The bearing body 3014 is transversely disposed at the center of the second connecting body 3012, and is used for providing connecting stations for two ends of the opposite-pull assembly 4, and the bearing body 3014 is of a concrete structure, so as to ensure high connection strength and deformation resistance.
As shown in fig. 2 and 5, a third embodiment of the present invention proposes a split structure for laying a steam pipe, and the split assembly 4 includes at least:
a counter-cable 401 and a second boom 402;
wherein, two ends of the pair of pull cables 401 are connected to the connecting tower 301;
wherein, one end of the second suspender 402 is connected with the opposite pull cable 401, and the other end is connected with the bearing structure 1.
In the present embodiment, the counter pull assembly 4 is constituted by a counter pull cable 401 and a second boom 402.
Wherein the opposite cables 401 are two and arranged at both sides of the load bearing structure 1, and the second suspension rod 402 is connected between the opposite cables 401 and the load bearing structure 1 to provide a force to the load bearing structure 1.
When the load bearing structure 1 is subjected to a large wind load, the opposite guys 401 and the second hanger bar 402 on both sides provide forces to the load bearing structure 1 towards both sides to slow down the deflection of the load bearing structure 1, in particular its deflection in the width direction, thereby ensuring the stability of the load bearing structure 1.
Furthermore, the main cable 3021 and the first boom 3022 of the present embodiment have the foregoing triangle structure, and can cooperate with the acting forces of the pull cable 401 and the second boom 402, so that the bearing structure 1 is relatively stable against wind load, and excessive shaking or deviation cannot occur, thereby ensuring the stability of the steam pipe 2.
As shown in fig. 5, a fourth embodiment of the present invention provides a split structure for laying a steam pipeline, and on the basis of the previous embodiment, the second suspenders 402 are plural, and with the center line of the width of the carrying structure 1 as a reference line, the plural second suspenders 402 have lengths increasing in the direction from the reference line to one end of the carrying structure 1.
In this embodiment, the length of the second boom 402 is optimized.
The reason is that in the prior art, the opposite cable 401 is generally arranged parallel or nearly parallel to the load bearing structure 1, which form makes the restraining force provided by the opposite cable 401 to the load bearing structure 1 relatively weak. It is desirable for this embodiment that the force provided to the load bearing structure 1 by the pull cable 401 approaches rigidity to provide more direct restraint to the load bearing structure 1. Thus, on the one hand, tension is provided to the load bearing structure 1 by the second boom 402, and on the other hand, when the tensile cord 401 is defined according to the parameters of embodiment 1, it will deform in the middle section of the load bearing structure 1, so that the two tensile cords 401 will assume an X-shaped configuration in a top view, which configuration helps to provide a more stable tension to the tensile cord 401 in the middle section, and this tension is generated by the deformation of the tensile cord 401, which will always exist to ensure the stability of the load bearing structure 1 in this position.
As shown in fig. 9 to 10, a fifth embodiment of the present invention provides a pull-up structure for steam pipe laying, and further includes, on the basis of the previous embodiment:
an adjustment assembly 6, an end of each of the second booms 402 being connected to the pair of guys 401 by the adjustment assembly 6;
wherein the adjustment assembly 6 is configured to adjust the value of the second vector of the pair of cables 401.
In this embodiment, an adjustment assembly 6 is also included.
It has further been found that the length of the plurality of second booms 402 may be optimized in order to ensure that the cable 401 can be arranged according to the parameters and shape of the previous embodiments. However, as the length of the opposite cable 401 increases, the foregoing manner may not be able to more accurately adjust the parameters of the opposite cable 401 within the set parameter range.
Based on this, adding the adjustment assembly 6, by adjusting the adjustment assembly 6, the water can be made to adjust the second vector of the pull cable 401. In particular, the length of the second boom 402 may be adjusted to vary the minimum width of the pair of cables 401 from the load bearing structure 1. It is foreseen that the adjusting assembly 6 increases the accuracy of the adjustment of the second vector, so that the second vector of the pull cable 401 can be adjusted more accurately within the set parameter range, thereby ensuring the stability of the bearing structure 1.
Specifically, the end of the second boom 402 may be provided with threads, the adjustment assembly 6 is a threaded sleeve, the connection of the adjustment assembly 6 to the end of the second boom 402 is achieved by screwing, and the adjustment of the second vector is achieved.
A sixth embodiment of the present invention proposes a split structure for laying a steam pipeline, and, on the basis of the previous embodiment, the adjusting assembly 6 includes at least:
a flexible member 601, said flexible member 601 forming a flexible connection with said pair of pull cables 401.
In this embodiment, it is further found that the opposite cable 401 is also subject to wind load to oscillate or rock. If this action affects the load-bearing structure 1, instability of the load-bearing structure 1 may result. In the prior art, the connection position between the second boom 402 and the opposite cable 401 is usually set to be a rigid connection, and the rigid connection has relatively strong conduction effect on the acting force, so that the adverse effect on the opposite cable 401 on the load-bearing structure 1 is increased.
Based on this, the adjustment assembly 6 adds a flexible member 601. That is, the flexible member 601 and the opposite cable 401 are connected by the flexible member 601, and when the opposite cable 401 is subjected to wind load, the flexible member 601 absorbs a certain kinetic energy, thereby slowing down the further transmission of the kinetic energy toward the load bearing structure 1 to weaken the adverse effect on the load bearing structure 1.
Specifically, the flexible member 601 is formed by twisting a plurality of ropes having elastic properties in a twist shape, and has a characteristic of absorbing a certain kinetic energy in addition to improving the connection strength.
As shown in fig. 3, a seventh embodiment of the present invention provides a split structure for laying a steam pipeline, and on the basis of the previous embodiment, a plurality of secondary cables in a wire harness structure are formed at two ends of the main cable 3021, and each secondary cable is anchored in the connection tower 301.
In this embodiment, it is further found that in the prior art, main cable 3021 is typically connected to connection tower 301 in two forms:
first, main cable 3021 passes through connection tower 301 and is anchored to the ground. This form may result in the coupling tower 301 providing a weakened force to the main cable 3021, the main cable 3021 being primarily subjected to ground based forces rather than the coupling tower 301 providing a force;
second, the end of the main cable 3021 is connected to the connection tower 301. Although this form makes the connection tower 301 act as the main pulling structure of the main cable 3021, the connection area between the end of the main cable 3021 and the connection tower 301 is small, and the stress is concentrated, so that the connection tower is easily broken.
Based on this, the present embodiment performs the following optimization:
first, the main cable 3021 is still connected to the connection tower 301, so that the connection tower 301 provides a relatively strong acting force as a main pulling structure, and the end portion of the main cable 3021 is divided into a plurality of bundles of sub-cables, each of the sub-cables is connected to the connection tower 301, so that the connection area between the connection tower 301 and the main cable 3021 is increased, and the stress is prevented from being too concentrated, thereby avoiding the risk of fracture.
As shown in fig. 1 to 2, an eighth embodiment of the present invention provides a pull-up structure for steam pipe laying, and further includes, on the basis of the previous embodiment:
a cable-stayed foundation 701 and a cable-stayed structure 702;
wherein, the cable-stayed foundation 701 is positioned at two sides of the length direction of the bearing structure 1;
one end of the cable-stayed structure 702 is connected with the connecting tower column 301, and the other end is connected with the cable-stayed foundation 701;
the cable-stayed structure 702 provides a third acting force F3 to the connecting tower 301, and the third acting force F3 forms an included angle E with the connecting tower 301;
wherein, the value range of contained angle E is: 30 ° to 60 °.
In this embodiment, since the connection tower 301 is stressed unidirectionally, that is, is subjected to the force of the main cable 3021 side, there is a risk that the connection tower 301 will topple over.
Based on this, a cable-stayed foundation 701 and a cable-stayed structure 702 are added. The cable-stayed structure 702 is connected to the other side of the connecting tower 301 to provide a third acting force F3 on the other side, so as to balance the acting force of the connecting tower 301 on the main cable 3021 side, so as to ensure that the stress of the connecting tower 301 is stable.
And, the direction of the third acting force F3 forms an angle E with the connecting tower 301, and the angle E is within the aforementioned parameter range, so as to ensure that a relatively strong diagonal tension is provided.
Specifically, the cable-stayed structure 702 is composed of a plurality of cable-stayed cables.
