Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a multi-row hole cast-in-place concrete thermal insulation shear wall. Background Technique

[0002] Compared with the traditional shear wall structure, the thermal insulation shear wall has good thermal insulation effect, so it is widely used in various building fields. After retrieval, the patent with the authorization number of CN101812880A in China discloses a multi-row hole cast-in-place concrete thermal insulation shear wall. Although this wall combines the advantages of good overall performance of the concrete shear wall and good thermal insulation performance of the energy-saving wall, and the construction of this wall is simple, the reserved hole mold used is convenient for production and processing, and at the same time, materials are saved, and it has great application value. However, since multiple vertical holes are opened inside this wall, the concrete structure inside the wall is greatly reduced, and thus although the inside of the wall has a thermal insulation effect, the overall structure has a reduced structural strength due to the existence of the vertical holes. Content of the Utility Model

[0003] Aiming at the deficiencies of the prior art, the utility model provides a multi-row hole cast-in-place concrete thermal insulation shear wall, which solves the problem that in the existing wall, due to the opening of multiple vertical holes inside the wall, the concrete structure inside the wall is greatly reduced, and thus although the inside of the wall has a thermal insulation effect, the overall structure has a reduced structural strength due to the existence of the vertical holes as mentioned in the background technique.

[0004] To achieve the above purposes, the utility model is realized through the following technical solutions: A multi-row hole cast-in-place concrete thermal insulation shear wall, including a cast-in-place main body, templates, first die holes and anchor bolts. Templates are arranged on both sides of the cast-in-place main body. One ends of the two templates are connected to each other through side plates. Two ends of the side plates are respectively welded to the templates. The templates on both sides of the cast-in-place main body are connected to each other through anchor bolts. Nuts are threadedly connected to both ends of the anchor bolts. A plaster layer is arranged on the outer side of the templates. First die holes and second die holes are arranged inside the cast-in-place main body. In order to improve the firmness of the plaster layer, a wire mesh can be welded on the outer side of the templates.

[0005] Preferably, one ends of adjacent templates are mutually attached, and the templates are of a multi-bent structure, so that the connection parts between the templates can be mutually engaged, thereby improving the connection firmness between the templates.

[0006] Preferably, the cast-in-place main body is a concrete cast-in-place structure, and anchor bolts are inserted inside the cast-in-place main body. The anchor bolts are arranged at equal intervals from top to bottom. A plurality of the internal anchor bolts are retained inside the cast-in-place main body after the concrete solidifies, thereby playing a role in strengthening the whole.

[0007] Preferably, the first die holes and the second die holes are flat, and the first die holes and the second die holes are arranged at equal intervals inside the cast-in-place main body, and the first die holes and the second die holes are offset from each other, and the first die holes and the second die holes are filled with thermal insulation foam. After the concrete solidifies, a plurality of cavities are formed inside through the first die holes and the second die holes. By filling thermal insulation materials inside the cavities, the thermal insulation effect is achieved.

[0008] Preferably, the first die holes and the second die holes are connected by connecting ribs. The two ends of the connecting ribs are respectively welded to the outer walls of the first die holes and the second die holes. Bolt holes are formed on both sides of the first die holes, and anchor bolts are inserted into the bolt holes, so that the first die holes can be fixed by the anchor bolts to prevent slipping inside the cast-in-place main body.

[0009] Preferably, circular grooves are formed on the concave surface of the outer side of the formwork, and the circular grooves are arranged at equal intervals from top to bottom. And the nuts are located on the surface of the concave surface of the outer side of the formwork, and the nuts are fixed inside the grooves on the outer side of the formwork, which is beneficial to avoid protruding from the wall and thus maintain aesthetics.

[0010] The utility model provides a multi-row hole cast-in-place concrete thermal insulation shear wall, which has the following beneficial effects:

[0011] (1) For the multi-row hole cast-in-place concrete thermal insulation shear wall, a plurality of first die holes and second die holes are arranged inside the formwork, and the first die holes are fixed by anchor bolts. By pouring concrete into the formwork, after the concrete solidifies, a plurality of cavities are formed inside through the first die holes and the second die holes. By filling thermal insulation materials inside the cavities, the thermal insulation effect is achieved. At the same time, a plurality of internal anchor bolts remain inside the cast-in-place main body after the concrete solidifies, so as to reinforce the whole, which is beneficial to make up for the strength reduction caused by the reduction of concrete. At the same time, both ends of the anchor bolts are connected with nuts, so that the connection between adjacent formworks can be tightly connected.

[0012] (2) For the multi-row hole cast-in-place concrete thermal insulation shear wall, after the concrete solidifies, it is not necessary to remove the formwork, the first die holes and the second die holes. The formworks are fixed on both sides of the cast-in-place main body by anchor bolts and nuts. To a certain extent, the metal formworks and the first die holes and the second die holes can also improve the longitudinal compressive capacity of the wall, thus reducing the steps of removing the formwork after the existing concrete is poured. The nuts are fixed inside the grooves on the outer side of the formwork, which is beneficial to avoid protruding from the wall and thus maintain aesthetics.

[0013] Therefore, the problem that in the existing wall, due to the opening of a plurality of vertical holes inside the wall, the concrete structure inside the wall is greatly reduced, and thus although the wall has a thermal insulation effect, the overall structure has a reduced structural strength due to the existence of the vertical holes is solved.

Thermal insulation foam is filled inside the first die holes 5 and the second die holes 6. After the concrete solidifies, a plurality of cavities are formed inside through the first die holes and the second die holes. The first die holes 5 and the second die holes 6 are connected by connecting bars 7. Both ends of the connecting bars 7 are welded to the outer walls of the first die holes 5 and the second die holes 6 respectively.

By pouring concrete into the formwork 2, after the concrete solidifies, multiple cavities are formed inside through the first die holes 5 and the second die holes 6. By filling thermal insulation materials inside the cavities, it thus has the thermal insulation effect. At the same time, multiple internal anchor bolts 9 remain inside the cast-in-place main body 1 after the concrete solidifies, thus playing a role in strengthening the whole, and further being beneficial to making up for the strength reduction caused by the reduction of concrete. At the same time, both ends of the anchor bolts 9 are connected with nuts 10, enabling the connection between adjacent formworks 2 to be tightly connected. After the concrete of this thermal insulation wall body solidifies, there is no need to remove the formwork 2, the first die holes 5 and the second die holes 6. The formworks 2 are fixed on both sides of the cast-in-place main body 1 through the anchor bolts 9 and the nuts 10. To a certain extent, the support of the formwork 2 made of metal material, the first die holes 5 and the second die holes 6 can also improve the longitudinal compressive capacity performance of the wall body, thus reducing the steps of removing the formwork after the existing concrete is poured.
