The inner leaf wall panel 10 includes a first portion 11 and a second portion 12 disposed at a first angle, in this embodiment, the first angle is 90 °, that is, the first portion 11 and the second portion 12 of the inner leaf wall panel 10 are perpendicular and orthogonally joined, so that the inner leaf wall panel 10 is integrally "L-shaped", but the first portion 11 and the second portion 12 of the inner leaf wall panel 10 may also be joined at other angles, that is, the first angle may be other angles, for example, 80 °, 95 °, 120 °, and so on.
The middle wall plate 20 comprises a first part 21 and a second part 22 arranged at a second angle, in this embodiment, the second angle is 90 °, that is, the first part 21 and the second part 22 of the middle wall plate 20 are perpendicular and are orthogonally spliced, so that the whole middle wall plate 20 is in an "L shape", but the first part 21 and the second part 22 of the middle wall plate 20 can also be spliced at other angles, that is, the second angle can be other angles, such as 80 °, 95 °, 120 ° and the like; the middle wall board 20 is connected with the inner leaf wall board 10 through a plurality of first tie pieces 40, and encloses a first cavity 10a with the inner leaf wall board 10, and a wall structure reinforcing steel bar 30 is arranged in the first cavity 10a, so that a structure function area of the shear wall body 1 is formed.
The outer leaf wall panel 50 comprises a first portion 51 and a second portion 52 arranged at a third angle, in this embodiment, the third angle is 90 °, that is, the first portion 51 and the second portion 52 of the outer leaf wall panel 50 are perpendicular and orthogonally joined, so that the outer leaf wall panel 50 is overall "L-shaped", but the first portion 51 and the second portion 52 of the outer leaf wall panel 50 may also be joined at other angles, that is, the third angle may be other angles, for example, 80 °, 95 °, 120 °, and so on. The outer leaf wallboard 50 is connected with the middle wallboard 20 through a plurality of second tie pieces 41 and encloses into a second cavity 50a with the middle wallboard 20, and a heat preservation wallboard 60 is arranged in the second cavity 50a, and the heat preservation wallboard 60 is connected with the second tie pieces 41 to form a heat preservation functional area of the shear wall body 1.
Therefore, in the shear wall body 1 of the present application, in the thickness direction (shown in the direction H in fig. 3), the shear wall body 1 is composed of two functional areas, namely, a structural functional area and a thermal insulation functional area. The shear wall body 1 is a prefabricated component with a cavity structure, the shear wall body 1 is provided with a first cavity 10a and a second cavity 50a, and is integrated with the external wall heat preservation and the structural steel bars 30 of the shear wall body 1, the shear wall body 1 is manufactured in a factory, after being hardened, is demoulded and maintained, is transported to a site for assembly, is hoisted in place according to the requirements of a construction drawing, and is poured with concrete in the first cavity 10a to form the building wall body. Manual formwork supporting, formwork removing and heat preservation operations on a construction site are omitted, and even later manual plastering operations are omitted.
In a factory, the heat-insulating wall board 60 is integrated with the middle wall board 20 and the outer leaf wall board 50 into a prefabricated part through the second pulling piece 41, so that manual operation on a construction site is avoided, and the phenomenon that a heat-insulating protective layer is peeled off due to quality problems is avoided. The shear wall body 1 of this application adopts the structure of taking the cavity, wants lighter than traditional precast concrete side fascia dead weight, and the cost of manufacture is lower, the preparation efficiency is higher. Can effectively reduce the cost and is more beneficial to the popularization and the comparison of the assembly type building technology.
In addition, as shown in fig. 3, the wall structure reinforcing steel bars 30 inside the first cavity 10a integrate the wall body reinforcing steel bars (in the region of A, B in fig. 3) and the hidden column reinforcing steel bars (outside the region of A, B in fig. 3) of the shear wall, that is, the hidden column reinforcing steel bars are arranged at the two ends of the shear wall body 1, the wall body reinforcing steel bars are arranged in the middle part, and therefore, the reinforcing steel bars do not need to be manually bound on site, and a large amount of labor and material costs are saved. The first cavity 10a is a stressed structure layer of the shear wall body 1, and in the building construction process, after the shear wall body 1 is hoisted in place, concrete is poured into the first cavity 10a to fill the cavity, and the inner leaf wall panels 10 and the middle wall panels 20 on the two sides of the concrete are templates for pouring the concrete. Before concrete is poured, the cavity opening parts at the two ends of the shear wall body 1 can be sealed by using templates. The poured concrete forms a structural stressed wall together with the wall construction rebar 30 integrated within the first cavity 10 a. And, concrete is poured into the first cavity 10a, so that the wall body part and the hidden column part of the shear wall are formed by one-time pouring, and the condition that two construction processes of cast-in-place and prefabrication are staggered does not exist.
Moreover, the first tie member 40 and the second tie member 41 are installed in the shear wall body 1, and do not need to be installed and disassembled manually on the construction site, so that the labor cost can be effectively saved compared with the traditional counter-pulling screw, the construction period is shortened, the building industrialization degree is improved, and the cost can be effectively reduced compared with a fiber reinforced composite (FRP) tie member or a stainless steel tie member in a precast concrete wall body, and the popularization of the assembly type building technology is facilitated.
Alternatively, the inner leaf wall panels 10 and the middle wall panels 20 are tensile wall panels to resist lateral pressure generated when concrete is poured in the first cavity 10a, and the materials used include, but are not limited to, cement-based composite materials, metals, and synthetic composite materials.
Optionally, the outer leaf wall panel 50 is a decorative layer of the shear wall body 1 and a protective layer of the thermal insulation wall panel 60, so as to protect the thermal insulation wall panel 60 from external force and environmental damage, and meanwhile, the outer leaf wall panel 50 may also be integrated with an outer decoration of an outer wall, and the spraying and pasting processes of the outer wall decoration may be completed in a factory.
Alternatively, the thermal insulation wall board 60 may use a board with thermal insulation performance with fire-proof rating of B level or above, the surface of the thermal insulation wall board 60 may be coated or coated according to the requirement, and the position and range of the thermal insulation board are arranged according to the building drawing of the actual project.
Optionally, the first tie member 40 serves to connect the inner leaf wall panel 10 and the middle wall panel 20 together and to resist side pressure during concrete casting, and uses a processing material having a tensile strength, including but not limited to metal or synthetic composite material.
