Detailed Description
The following detailed description of embodiments of the present invention is provided in connection with the accompanying drawings and examples. The following examples are intended to illustrate the invention but are not intended to limit the scope of the invention.
In the description of the present invention, it should be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "connected," and "connected" are to be construed broadly, e.g., as meaning either a fixed connection, a removable connection, or an integral connection; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. "first", "second", "third" and "fourth" do not denote any sequence relationship, but are merely used for convenience of description. The specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art. "Current" is the time at which an action is performed, multiple occurrences of which are recorded in real time over time.
Products, methods, and the like will be described in detail below with reference to basic designs, extended designs, and alternative designs.
A building wall body is shown in figures 1 and 2 and comprises an insulation template component, a concrete wall and a plurality of sleeves 8; wherein the first surface of the heat-insulating template component is tightly attached and fixedly connected to the second surface of the concrete wall; the heat preservation template component is formed by splicing a plurality of heat preservation templates 2; all the sleeves 8 penetrate through the concrete wall, and the pull pieces 1 which penetrate through the heat-insulation template component and the concrete wall freely penetrate through the sleeves 8; the first end face of the sleeve 8 is fixed on the first surface of the heat-preservation template component; the second end face of the sleeve 8 is fixed to the third surface of the concrete wall, and the second end face of the sleeve 8 and the third surface of the concrete wall are in the same plane.
The heat preservation template 2 is prefabricated product, and the scene can be cut, spliced, and the concrete wall is cast in situ, and sleeve 8 is fixed in heat preservation template 2 at the construction process, and wherein with sleeve 8 fixed in the concrete casting process, sleeve 8 remains in the building wall body. Wherein the sleeve 8 does not pass through the heat preservation template 2, and can not damage the heat preservation template 2. And sleeve 8's effect more lies in utilizing inside cavity to make things convenient for pulling-on piece 1 freely to pass from the well, keeps apart pulling-on piece 1 and concrete wall, and after having pour the concrete wall, pulling-on piece 1 can be followed and pulled out in the building wall body, can not be deposited in the building wall body. In the conventional construction, after a concrete wall is poured, the part of the pulling-on piece 1, which is positioned outside the heat-insulating template 2, is knocked off, and the pulling-on piece 1 in the rest part penetrates through the concrete wall and the heat-insulating template 2, so that a cold and hot bridge can be formed at the pulling-on piece 1 due to the fact that the metal material of the pulling-on piece 1 is different from that of the heat-insulating template 2 and the heat conductivity coefficient is different. In the technology, the pull piece 1 is not arranged in the final building wall, so that the problems of different materials and cold and hot bridges can be avoided.
In some embodiments, the concrete wall is internally provided with tie bars 5. The first surface of the heat preservation template 2 can be anchored and extended to a concrete pouring position through the anchor bolts 6, the anchor bolts 6 are poured in concrete in the concrete pouring process, and the connection strength of the heat preservation template 2 and a concrete wall can be reinforced.
The sleeve 8 is a hollow structure and may be cylindrical in some embodiments. The sleeve 8 is preferably sized to allow the pull tab 1 to pass through it, and the material may be selected from plastic and steel. One end of the sleeve 8 is provided with an installation position for installing the heat preservation template component, and the first end of the sleeve 8 is propped against the first surface of the heat preservation template 2 (namely the surface of the heat preservation template component fixedly connected with the concrete wall), and then is fixed on the first surface through the installation position. The second end of the sleeve 8 is fixedly connected to a third surface of the concrete wall (i.e. the surface of the concrete wall adjacent to the interior of the house). It should be noted that the sleeve 8 does not pass through the insulating form 2, so that no through-holes are left in the insulating form 2. When the outside air temperature changes or water flows through the heat preservation formwork 2, the condition that the sleeve 8 introduces water into the building wall body can not occur. The sleeve-shaped cylinder adopted in the prior art penetrates through the heat insulation template 2, after the concrete wall is poured, the sleeve-shaped cylinder and the pulling piece 1 are pulled out together, the sleeve-shaped cylinder can leave a large hole in the heat insulation template 2, a construction worker needs to fill in the hole at the later stage, the requirement on the filling quality is high, and if filling leakage occurs or filling is not solid, the phenomenon that water is introduced into the construction wall is caused, namely the wall leaks.
In the building industry, the inside of the existing aluminum template system only depends on supporting the pull sheet 1, the stability of the template is difficult to guarantee, and the harmful phenomena of 'die running', 'die expansion' and the like can be caused by improper operation. Moreover, the thickness of the wall body needs to meet certain standards, and the accurate arrangement of the sleeve 8 standardizes the pouring thickness of the concrete wall, so that the change of the distance between the inner supporting template 4 and the heat preservation template 2 is avoided. The sleeve 8 serves as a support.
In consideration of the different forces on the wall, in the preferred embodiment, the sleeve 8 is distributed gradually sparsely from bottom to top.
On the other hand, in order to improve the convenience of pulling-out of pulling-on piece 1, and reduce the destruction degree of pulling-on piece 1 to heat preservation template 2, preferably the splicing seam that adjacent two heat preservation templates 2 were passed to pulling-on piece 1, the size of splicing seam department is judged to the conventionality is enough to place pulling-on piece 1, and pulling-on piece 1 pulls out the back, and the constructor carries out the external decoration outside the building wall, and the shop pastes net cloth, directly paints the splicing seam when paining outer ornaments such as cement and pasting ceramic tile. Since the pull tab 1 penetrates through the sleeve 8, in the finally formed building wall, the first end face of the sleeve 8 spans the splicing seams of the two adjacent heat preservation formworks 2, and the pull tab 1 penetrates through the splicing seams spanned by the first end face of the sleeve 8. The first end face of the sleeve 8 is fixedly connected with at least two heat preservation templates 2.
It should be noted that the pulling-on piece 1 can pass through the heat preservation template 2 under some circumstances, and perforation can be set up on the heat preservation template 2 in the actual operation, because the pulling-on piece 1 is thinner, the pulling-on piece 1 is taken out from the heat preservation template 2 after concrete is poured, and the perforation can be smeared when the exterior finishing surface is decorated in the later stage of the building wall body.
Further, because the inner supporting formwork 4 before the concrete wall is poured is an existing structure, generally a steel mould, a wood mould, an aluminum mould and the like, the structure and the size are fixed, in order to match the structure of the inner supporting formwork 4, the size of the heat preservation formwork 2 on the building wall is preferably equal to the unit size of the inner supporting formwork 4 when the concrete wall is poured. Therefore, the second end face of the sleeve 8 can also span the splicing seams of the two adjacent inner supporting templates 4 during early supporting, and the pulling piece 1 is pulled out of the splicing seams.
And the flatness of the outer wall adopting the traditional wood formwork system construction method is difficult to reach +/-5 mm of the standard requirement, so that the subsequent construction difficulty is large, the construction period is increased, and the later leveling construction cost is high.
Based on the problems, in order to improve the flatness of the concrete wall, the outer-side formwork can be optimized when supporting in the early stage, and the aluminum formwork is adopted, so that the cost is lower and is saved compared with the outer side of the original aluminum formwork system. The inner supporting template 4 preferably adopts an aluminum mould supporting structure. The aluminum mould supporting structure can provide excellent mechanical support, is simple and convenient to construct and install, does not produce building rubbish, and has high turnover rate and high recycling value. On the other hand, the aluminum mould supporting structure has lighter weight and can be manually carried, assembled and disassembled without the assistance of large-scale heavy-duty mechanical equipment; the application range is wide, the binding force between the aluminum mould and the concrete wall is not large, the demoulding effect is good, and the contact surface with the concrete is smooth and flat; furthermore, the aluminum mould is acid-resistant and corrosion-resistant, and is more suitable for various complex construction environments of building walls. In the early construction period, the sleeve 8 is only jacked on the inner supporting template 4, after the concrete wall is poured, the inner supporting template 4 is dismantled, the inner supporting template 4 is naturally separated from the sleeve 8, and the sleeve 8 stably exists in the concrete wall.
Of course, in other embodiments, the inner supporting template 4 may be replaced by a wood mold, a steel mold, or the like.
Can be with the design of the first end terminal surface of sleeve 8 for the flange face in sleeve 8's first terminal surface and heat preservation template 2 fixed connection, the flange face is bigger for telescopic well cross section area, and is bigger with the area of contact of heat preservation template to improve telescopic support effect.
Next, a method of constructing a building wall is provided, as shown in fig. 3 and 4 (pull tab not shown), which includes:
step 110, preparing a heat preservation template 2 and forming a heat preservation template component;
the heat preservation template 2 is a prefabricated product, the cutting is carried out on the construction site according to the size of the inner supporting template 4, and then the cut heat preservation template 2 is connected into a heat preservation template component by adopting a nylon connecting piece and the like. The nylon connecting piece is a nylon anchor bolt 6 special for the heat preservation template 2, and an anchor bolt 6 position hole is reserved on the heat preservation template 2 and is directly penetrated.
Step 120, installing a heat-insulating template component, connecting a connecting piece on the first surface of the heat-insulating template with the precast wall body reinforcing steel bars, and installing an outer formwork 3 of the heat-insulating template component;
the outer side formwork 3 is used for supporting the heat preservation formwork member from the outside so as to resist the acting force of concrete on the heat preservation formwork 2 during concrete pouring, increase the stability of the heat preservation formwork 2 and promote the overall smoothness of the heat preservation formwork member.
The outer side formwork 3 can adopt a frame structure, such as an aluminum frame, and the like, and applies uniform stabilizing force to the heat preservation formwork 2.
Concrete wall rebars 5 may be tied in this step. And anchor bolts on the heat preservation template are connected with the wall body reinforcing steel bars.
Step 130, installing a sleeve 8 on the first surface of the heat-insulating template component;
in the installation process, the first end face of the sleeve 8 is fixed on the heat preservation template 2. And the first end of the sleeve 8 is abutted and installed at the splicing seam between two adjacent heat preservation templates 2, so that the first end surface of the sleeve 8 stretches across the splicing seam. Sleeve 8 contact temperature steel form one side is provided with pier 81 and can prevents that self from warping and take out in order to make things convenient for pulling-on piece 1 to can play the effect of fulcrum in order to increase the stability of template system, improve the quality of concreting. Abutments 81 have a thickness of about 3mm to 5 mm.
Under the special condition, the pull piece 1 can be perforated on the heat preservation template 2, and the pull piece 1 is thinner, so that the pull piece 1 is drawn out of the heat preservation template 2 after concrete is poured, and the perforations can be smeared during later-stage exterior finishing of the building wall.
Step 140, installing the inner supporting template 4, and abutting the sleeve 8 on the surface of the inner supporting template 4;
in the process of installing the inner supporting template 4, the splicing seams of the inner supporting template 4 correspond to the splicing seams of the heat preservation template 2, so that the subsequent pulling-on piece 1 can conveniently penetrate. The splice joint abuts against the second end face of the sleeve 8.
In the embodiment, the inner supporting template 4 adopts an aluminum mould supporting structure; the aluminum film supporting structure is formed by splicing a plurality of aluminum die units; the size of the aluminum die unit is the same as that of the heat preservation template 2; mounting the inner supporting template 4, abutting the sleeve 8 in the surface of the inner supporting template 4, and enabling the second end surface of the sleeve 8 to cross the splicing seams of the two adjacent aluminum mould units; in the process of sequentially penetrating the pull piece 1 through the inner supporting template 4, the sleeve 8 and the heat-preservation template component and locking two ends of the pull piece, the pull piece 1 penetrates through a splicing seam spanned by the second end face of the sleeve 8.
150, sequentially penetrating the pull piece 1 through the inner supporting template 4, the sleeve 8 and the heat preservation template component and locking two ends of the pull piece;
the pulling piece 1 is in a slender sheet structure, and positioning through holes 7 are formed in two ends of the pulling piece; the locking structure of the pull piece 1 mainly comprises a pin shaft and a pin piece 10. One end of the pin shaft is provided with a pin cap, and the other end of the pin shaft is provided with a positioning hole 91 which transversely penetrates through the pin shaft; in the locking process, after the pulling-on piece 1 sequentially passes through the inner supporting template 4, the sleeve 8 and the pulling-on piece 1 of the heat-preservation template component, pin shafts respectively pass through the positioning through holes 7 at two ends of the pulling-on piece 1, and the pin pieces 10 pass through the positioning holes 91 for locking. The pin sheet is preferably a conical pin sheet, and when the pin sheet is inserted into the positioning hole, the size change of the end face of the conical pin sheet is utilized to improve the positioning effect.
The pulling piece 1 penetrates through the sleeve to combine and fix the inner and outer side templates and the die carrier through the pins 9, the number of holes formed on the pulling piece 1 is small, and the later plugging and waterproofing cost can be greatly reduced; because the aluminum template has good stability and flatness in a fixing mode, the flatness of the outer wall after demoulding can meet the standard requirement, and the flatness treatment cost after demoulding of the traditional template system is saved.
The pulling piece 1 is locked and can fix the position between the heat preservation template 2 and the inner supporting template 4 to resist the pouring acting force during concrete pouring.
Step 160, pouring concrete between the heat-insulating template component and the inner supporting and protecting template 4 to obtain a concrete wall;
step 170, removing the inner supporting template 4 and the outer side formwork 3;
step 180, the pull tab 1 is withdrawn.
