Description

A prefabricated perforated shear wall

technical field

The invention relates to a building prefabricated component, which is a prefabricated hole-row shear wall.

Background technique

The prefabricated components used in the construction industry have developed into many varieties. At present, there have been public reports on the prefabrication of shear walls. It still uses the structure of laminated slab shear walls. A row of holes is set in the middle of the wall, and connecting steel bars are set on the side of the wall; during construction, steel bars are installed in the row of holes. Concrete is poured after bundling. The disadvantage of this kind of prefabricated shear wall is that the steel bars at the upper and lower ends of the wall need different structures and binding methods, and the construction is difficult. The prefabricated shear wall is just a superimposed form of two concrete slabs. When it is necessary to construct on site, bury the steel bars in the row of holes and bind them before pouring concrete. Since a hole usually needs to embed multiple steel bars to enhance the strength and bearing capacity of the shear wall, it needs to be laid out according to the design requirements during construction. Concrete is poured after the steel bars are bundled, and it takes a lot of time to lay out the steel bars in each hole during the on-site construction, especially the on-site guidance of multiple technical personnel is required, the construction efficiency is low, and the construction quality of the prefabricated shear wall is difficult to guarantee.

The purpose of the present invention is to provide a prefabricated perforated shear wall, which can solve the deficiencies of the prior art.

In order to achieve the above object, the present invention is achieved through the following technical solutions: a prefabricated hole-row shear wall, comprising a prefabricated wall, several through holes are opened in the wall, and the first steel bar and the second steel bar are installed in each through hole. Reinforcing bar, the horizontal bar is fixed between the first reinforcing bar and the second reinforcing bar, a groove is provided on a side wall at one end of the height direction of the wall, the groove communicates with the through hole, and the outer ends of the two sides of the wall in the width direction are respectively fixed to the first square. Ring reinforcement and the second square ring reinforcement, the two ends of the first square ring reinforcement and the second square ring reinforcement are respectively fixed with respective wall sides. A horizontal through hole is provided on the upper inner wall in the height direction of the through hole, and the horizontal through hole is located between the first steel bar and the second steel bar. A connecting plate is installed between the pipe and the second casing, the middle part of the connecting plate is connected with the limiting plate, and the two ends of the limiting plate are respectively movably matched with respective transverse through holes. The upper end surfaces of the first steel bar and the second steel bar are higher than the upper end surface of the wall body, and the lower end surfaces of the first steel bar and the second steel bar are located in the same horizontal plane as the lower end surface of the wall body. The through holes are round or square. Ring-shaped helical teeth are arranged on the inner walls of the first sleeve and the second sleeve, and the tips of the ring-shaped helical teeth face downward in the height direction of the first steel bar or the second steel bar. The two ends of the first square ring reinforcement and the second square ring reinforcement are located at the outer edge of the wall.

The shear wall of the present invention is installed during construction after being prefabricated in a factory. No formwork is used during construction, and only the upper and lower ends of the upper and lower walls are bound. The construction is convenient and fast. During the construction, the steel bars of the upper and lower shear walls are directly bundled and then the concrete is poured. The design strength, shear force and bending moment force of the shear wall can be accurately guaranteed in the factory prefabrication. Since there is no need to arrange steel bars during on-site construction, the construction efficiency is greatly improved. The invention also has the advantages that the strength, load-bearing capacity and rigidity of the prefabricated shear wall are well guaranteed, and the service life of the prefabricated shear wall is greatly improved. The shear wall of the invention can be used in various high-rise buildings.

Detailed ways

The present invention will be further described with reference to the accompanying drawings.

A prefabricated hole-row shear wall of the present invention comprises a prefabricated wall body 1, several through holes 4 are opened in the body of wall 1, and a first steel bar 5 and a second steel bar 6 are installed in each through hole 4. The transverse bar 7 is fixed between the steel bar 5 and the second steel bar 6, and a groove 8 is provided on a side wall at one end of the height direction of the body of wall 1, and the groove 8 communicates with the through hole 4, and the outer ends on both sides of the body of wall 1 in the width direction are The first square ring rib 2 and the second square ring rib 3 are fixed, and the two ends of the first square ring rib 2 and the second square ring rib 3 are respectively fixed to the respective wall sides.

A horizontal through hole 13 is provided on the upper inner wall of the through hole 4 in the height direction of the present invention, and the horizontal through hole 13 is located between the first reinforcing bar 5 and the second reinforcing bar 6, and the first reinforcing bar 5 and the second reinforcing bar 6 are respectively installed with first The sleeve pipe 9 and the second sleeve pipe 10, the connection plate 11 is installed between the first sleeve pipe 9 and the second sleeve pipe 10, the middle part of the connection plate 11 is connected with the limit plate 12, and the two ends of the limit plate 12 are respectively connected with the respective transverse channels. Hole 13 is movable, this structure allows the shear wall to be prefabricated into a complete component in the factory, and directly hoisted on the building during construction.
