Problems solved by technology

[0003] The existing double-sided laminated wall panels have the following problems: (1) the inner wall panels and outer wall panels are prefabricated concrete, which has the disadvantages of long maintenance period, low production efficiency, large production site occupation, and heavy weight, which increases the The difficulty of transportation and installation increases the amount of labor; for example, the production process and production structure of a double-sided prefabricated thermal insulation laminated shear wall panel disclosed by the Chinese utility patent application publication number CN111673900A, the inner leaf wall panel and the outer leaf wall The slab needs to be poured to form, which is inconvenient for construction and low in production efficiency
In this way, there are the following problems: the plastic hinge of the general shear wall is formed at the bottom of the shear wall, but due to the effect of the grouting sleeve, the plastic hinge cannot be formed at the bottom of the shear wall, which results in the lower end of the grouting sleeve. The steel bar at the top of the layer is broken, resulting in brittle failure, difficult to control safety, and prone to safety hazards
In addition, it is not convenient for construction, and there are disadvantages of difficulty in connection and grouting

Embodiment 1

[0045] Such as Figure 1-8 As shown, a kind of dismantling-free double-sided laminated shear wall panel proposed in this embodiment includes an inner wall panel 1 and an outer wall panel 2; the inner wall panel 1 and the outer wall panel 2 are cement boards free from prefabrication; The wall panel 1 and the outer wall panel 2 are arranged opposite to each other, and there is an installation space between them; the inner cavity between the inner wall panel 1 and the outer wall panel 2 is installed with a steel bar truss.

[0046] Both sides of the steel bar truss are respectively connected to the inner wall panel 1 and the outer wall panel 2 by detachable assembly and connection. The steel bar truss includes longitudinal bars. 31 and the second longitudinal reinforcement 32 are arranged symmetrically, and the two ends of the first longitudinal reinforcement 31 and the second longitudinal reinforcement 32 protrude from the inner cavity to the outside, that is, the two ends of th...

Embodiment 2

[0073] Such as Figure 9-10 As shown, this embodiment proposes a non-demolition double-sided laminated shear wall panel, the other structures are the same as the first embodiment, the difference is that in this embodiment, the bottom of the longitudinal rib is provided with a lap joint 21 , the bottom of the longitudinal rib is bent to one side to form the above-mentioned overlapping part. During construction, the top of the longitudinal rib of the lower laminated shear wall panel is connected with the overlapping part 21 of the upper laminated shear wall panel, which can realize the upper and lower stacking The leveling of the combined shear wall panels solves the problem of misalignment of the upper and lower laminated shear wall panels in the first embodiment, and is more convenient for construction.

[0074] Utilizing the overlapping portion 21 can realize the bending dislocation of the longitudinal reinforcement of the laminated wall panels of the upper and lower layers, ...

Abstract

The invention discloses a disassembly-free double-sided superimposed shear wallboard, a superimposed shear wall and a construction method thereof. The disassembly-free double-sided superimposed shearwallboard comprises an inner wallboard and an outer wallboard, wherein an inner cavity is formed between the inner wallboard and the outer wallboard; a steel bar truss is mounted in the inner cavity;the inner wallboard and the outer wallboard are cement boards; split bolt holes are formed in the inner wallboard and the outer wallboard; two sides of the steel bar truss are respectively assembled and connected with the inner wallboard and the outer wallboard; the steel bar truss comprises a plurality of longitudinal bars, namely first longitudinal bars; the first longitudinal bars and second longitudinal bars extend out of the upper and lower ends of the cement boards; S-shaped connecting bars are connected between the first longitudinal bars and the second longitudinal bars symmetrical tothe first longitudinal bars; and transverse bar penetrating holes are formed in the first longitudinal bars and the second longitudinal bars. According to the disassembly-free double-sided superimposed shear wallboard disclosed by the invention, the problems that the prefabricated concrete wallboard is long in maintenance period, low in production efficiency and large in occupied production site,the connection and grouting difficulty of upper and lower steel bar sleeves of the prefabricated concrete wallboard is high, the safety is low and the like are effectively solved; and the inner wallboard and the outer wallboard are made of cement boards, so that the product quality is alleviated, and the production efficiency is improved.

Description

technical field [0001] The invention relates to the field of prefabricated buildings, in particular to a demolition-free double-sided laminated shear wall panel, a laminated shear wall and a construction method thereof. Background technique [0002] With the improvement of people's living standards, there is a higher demand for living environment. Traditional extensive housing construction methods have been gradually replaced by industrialized and integrated construction methods. In this context, the laminated slab concrete shear wall structure came into being. It can realize the standardization and modularization of residential structural components, reduce the erection of formwork supports on site, and shorten the construction period. [0003] The existing double-sided laminated wall panels have the following problems: (1) the inner wall panels and outer wall panels are prefabricated concrete, which has the disadvantages of long maintenance period, low production efficien...
