[0002] With the development of urban construction and the demand for infrastructure, a large number of new buildings are moving towards green environmental protection and efficiency. Taking wall casting as an example, traditional casting formwork uses wooden formwork or metal formwork, but the water absorption of wooden formwork and the high cost of metal formwork are not the best choice. Polyethylene foam board with high structural performance has become a new choice, which can also be used as an insulation layer after casting. During the formwork process, the formwork on both sides needs to be fixed by tensioning parts. The traditional tensioning screws need to be removed after the concrete is poured, which will leave screw holes. If these holes are not closed tightly later, there will be hidden dangers of water seepage.

[0047] It should be noted that the tie rod can be a solid rod or a hollow rod, and no specific limitation is made here.

[0048] In order to facilitate the installation and adjustment of the positioning part 2, an auxiliary part 23 for assisting the position adjustment of the positioning part 2 is provided on the side of the positioning part 2 opposite to the formwork space. That is, the positioning part 2 can be adjusted through the auxiliary part 23 on the outside of the template 3.

[0055] Compared with the traditional tension screw, the tension member of this solution does not need to be removed;

[0056] The anchor has the function of avoiding the need to dismantle the tension screws. As the anchors are closely arranged, the formwork is evenly stressed, thus avoiding the phenomenon of mold expansion during cast-in-place construction. At the same time, the use of supports such as back ribs is also reduced, thus greatly reducing on-site labor.

[0057] Embodiment 2:

[0062] Specifically, the positioning part 2 includes at least two structural forms:

[0063] 1. The first positioning unit 21 is a first positioning piece, which is provided with a threaded hole threadedly connected to the threaded segment 11 , and the second positioning unit 22 is a second positioning piece, which is provided with a threaded hole threadedly connected to the threaded segment 11 .

[0064] Second, the first positioning unit 21 is a first positioning T-nut having a threaded hole threadedly connected to the threaded section 11, and the second positioning unit 22 is a second positioning T-nut having a threaded hole threadedly connected to the threaded section 11.

This embodiment takes this as the best implementation method.

[0067] Second, threaded holes are provided inwardly at both ends of the tie rod, and at this time, the first positioning T-nut and the second positioning T-nut are installed in a superimposed manner. Specifically, the T-nut includes a rod portion and a sheet portion, wherein the rod portion has a threaded hole; in this embodiment, the rod portion of the second positioning T-nut is also provided with threads on the outside, and the position is adjusted by inserting the threads on the outside into the threaded hole at the end of the tie rod; and the rod portion of the first positioning T-nut is also provided with threads on the outside, and the position is adjusted by inserting the threads on the outside into the threaded hole on the inside of the rod portion of the second positioning T-nut.

[0068] In order to facilitate the installation and adjustment of the positioning part 2, an auxiliary part 23 for assisting the position adjustment of the positioning part 2 is provided on the side of the positioning part 2 opposite to the formwork space. That is, the positioning part 2 can be adjusted through the auxiliary part 23 on the outside of the template 3.

[0069] Specifically, the positioning part 2 is defined as a first positioning unit 21 clamped on the outside of the template 3, and a second positioning unit 22 clamped on the inside of the template 3.

[0071] The auxiliary part 23 can also be defined as an installation part. After the concrete in the formwork 3 is poured, the anti-cracking net 6 needs to be installed on the outer wall, but the traditional formwork system does not have a suitable installation part. In this embodiment, the auxiliary part 23 can assist in the installation of the anti-cracking net 6. Taking the auxiliary part 23 as a hole as an example, the mesh of the anti-cracking net 6 can be inserted into the air and fixed through the plug 5.

[0072] Furthermore, after the formwork system casts the wallboard, the wallboard is used to insulate the exterior wall. The exterior wall itself can be insulated by insulation materials, but the anchors are made of metal and are prone to heat conduction and temperature loss. To solve this problem, a preferred implementation of this embodiment is to wrap the positioning part with an insulation sleeve to play a role in insulation and prevent heat transfer through the anchors from causing temperature loss in the inner space of the wall. Preferably, the insulation sleeve is a nylon sleeve, which can be directly mounted on the first positioning unit (this embodiment does not provide a specific illustration, but a person skilled in the art should be able to know based on the above description).

[0073] The technical effects of the above technical solution of the utility model come from one or more of the following combinations:

[0074] In this embodiment, after the template is fixed by the anchor, there is no need to remove the anchor;

[0075] The anchor part of the anchor is fixedly connected to the cast structural reinforcement of the template to form a truss structure. When installing the template, it only needs to be installed on both sides of the truss, and the two ends of the anchor provide installation positions. Using a high-strength foam cotton template, it is only necessary to insert the two ends of the anchor part into the foam cotton template respectively;

[0076] The anchor has the function of avoiding the need to dismantle the tension screws. As the anchors are closely arranged, the formwork is evenly stressed, thus avoiding the phenomenon of mold expansion during cast-in-place construction. At the same time, the use of supports such as back ribs is also reduced, thus greatly reducing on-site labor.

[0077] Furthermore, the utility model is described in detail above in conjunction with the embodiments of the drawings, and a person skilled in the art can make various variations of the utility model according to the above description.
