Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of construction, and in particular relates to a prefabricated component of a double-sided cast-in-situ concrete steel bar grid sandwich insulation board. Background Art
[0002] The current prefabricated components of insulation walls generally include insulation boards and steel mesh on both sides. A distance needs to be reserved between the steel mesh and the insulation boards to form a casting chamber. The prefabricated components are pre-produced in the factory, then transported to the construction site for splicing, and then continue to be cast, which can improve construction efficiency.
[0003] However, the connection strength between the insulation board and the steel grid of the prefabricated components is low. During the pouring process, the castable will impact the insulation board, which can easily cause the relative position of the insulation board and the steel grid to shift, thereby affecting the wall structure. Utility Model Content
[0004] In order to solve the problems existing in the above-mentioned prior art, the utility model provides a prefabricated component of a double-sided cast-in-place concrete steel grid sandwich insulation board. By adding limiting ribs on both sides of the insulation board, the insulation board and the steel grid are limited by the limiting ribs, thereby preventing the deviation of the insulation board.
[0005] The specific technical solution adopted in this utility model is:
[0006] The double-sided cast-in-place concrete steel grid sandwich insulation board prefabricated component includes multiple groups of prefabricated units connected end to end. The prefabricated units include steel grids on both sides and insulation boards clamped between the steel grids. Adjacent prefabricated units are connected by means of binding between the steel grids. Limiting bars arranged in the horizontal direction are also provided between the steel grids and the insulation boards. The limiting bars are U-shaped rod structures, and the bent ends of the limiting bars are formed into bent portions. The bent portion on one side of the limiting bar abuts against the steel grid and forms a binding fixation, and the bent portion on the other side of the limiting bar abuts against the surface of the insulation board. The distance between the steel grid and the insulation board is formed by means of the limiting bars to form a fixed distance.
[0007] The preset unit also includes a fixing component, which is arranged in a rectangular array in multiple groups. The fixing component includes two oblique inserted bars arranged in an X-shaped cross. The intersection of the oblique inserted bars is located inside the insulation board. The two ends of the oblique inserted bars respectively pass through the steel mesh on both sides and are tied and fixed to the steel mesh.
[0008] The fixing assembly also includes a tie bar arranged in the vertical direction, and the two ends of the tie bar are hook-shaped structures and formed into hook parts. The hook parts at both ends of the tie bar are respectively hooked and tied to the oblique inserted bars on the upper and lower sides.
[0009] The fixing assembly also includes reinforcing ribs in a U-shaped rod structure, which are arranged along a horizontal plane parallel to the steel mesh. The grooves of the reinforcing ribs are placed on the surface of the tensioning bars and are buckled with the steel mesh. The bent portions on both sides of the reinforcing ribs pass through the steel mesh and are tied and connected to the steel mesh.
[0010] The distance between the end of the obliquely inserted reinforcement and the supporting formwork is 10-20 mm.
[0011] The beneficial effects of the utility model are:
[0012] In the utility model, limiting ribs are added on both sides of the insulation board, and the insulation board and the steel mesh are limited by the limiting ribs, thereby preventing the insulation board from deflecting. The limiting ribs can be installed when making prefabricated components. According to the required wall size, the distance between the insulation board and the steel mesh on both sides is calculated, and then the two ends of the steel bar are bent, and one side is tied and fixed to the steel mesh.

[0016] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:
[0017] The prefabricated component of double-sided cast-in-place concrete steel grid 1 sandwich insulation board 2 includes multiple groups of prefabricated units connected end to end. The prefabricated units include steel grids 1 on both sides and insulation boards 2 clamped between the steel grids 1. Adjacent prefabricated units are connected by binding between the steel grids 1. Limiting bars 3 arranged in the horizontal direction are also provided between the steel grids 1 and the insulation boards 2. The limiting bars 3 are U-shaped rod structures, and the bent ends of the limiting bars 3 are formed into bent portions. The bent portion on one side of the limiting bar 3 abuts against the steel grid 1 and forms a binding fixation, and the bent portion on the other side of the limiting bar 3 abuts against the surface of the insulation board 2. The distance between the steel grid 1 and the insulation board 2 is formed by the limiting bars 3 to form a fixed distance.
[0018] Currently, the connection strength between the insulation board 2 and the steel grid 1 of the prefabricated component is low. During the pouring process, the castable will impact the insulation board 2, which may easily cause the insulation board 2 and the steel grid 1 to shift relative to each other, thereby affecting the wall structure.
[0019] Therefore, in the present invention, by adding limiting ribs 3 on both sides of the insulation board 2, the insulation board 2 and the steel mesh 1 are limited by the limiting ribs 3, thereby preventing the insulation board 2 from deflecting. The limiting ribs 3 can be installed during the production of prefabricated components. According to the required wall dimensions, the distance between the insulation board 2 and the steel mesh 1 on both sides is calculated. Then, the two ends of the steel bars are bent and one side is tied to the steel mesh 1 to secure it.
[0020] In addition, size adjustments often occur at the construction site. When the distance between the insulation board and the steel mesh 1 on both sides needs to be adjusted, since the adjustment distance is usually small, the limiting rib 3 can be removed, and then the side of the limiting rib 3 on the side of the steel mesh 1 can be bent back or continued to bend to avoid the length of the bending portion of the limiting rib 3 close to the insulation board 2 being reduced, and to ensure that there is a larger contact area between the bending portion and the insulation board 2 to reduce the pressure exerted by the bending portion on the insulation board 2, and to avoid the bending portion puncturing the insulation board 2.
[0021] The pre-installed unit also includes a fixing assembly, which is arranged in a rectangular array in multiple groups. The fixing assembly includes two obliquely inserted bars 4 arranged in an X-shaped cross pattern. The intersection of the obliquely inserted bars 4 is located inside the insulation board 2. The two ends of the obliquely inserted bars 4 pass through the steel mesh 1 on both sides and are tied and fixed to the steel mesh 1. The intersection of the obliquely inserted bars 4 is located inside the insulation board 2, thereby enhancing the structural strength and fixing strength of the insulation board 2, ensuring that the insulation board 2 does not shift after being squeezed by the castable.
[0022] The fixing assembly also includes a tie bar 5 arranged in the vertical direction. The two ends of the tie bar 5 are hook-shaped structures and form hook parts. The hook parts at both ends of the tie bar 5 are hooked and tied to the obliquely inserted bars 4 on the upper and lower sides respectively. Through the arrangement of the tie bar 5, the displacement of the obliquely inserted bars 4 can be prevented, thereby further avoiding the displacement of the insulation board 2.
[0023] The fixing assembly also includes a reinforcing rib 6 in a U-shaped rod-shaped structure. The reinforcing rib 6 is arranged along a horizontal plane parallel to the steel mesh 1. The notch of the reinforcing rib 6 is placed on the surface of the tension bar 5 and is buckled with the steel mesh 1. The bent portions on both sides of the reinforcing rib 6 pass through the steel mesh 1 and are tied and connected to the steel mesh 1. The reinforcing rib 6 can connect multiple groups of tension bars 5 together, thereby forming a whole between multiple groups of fixing assemblies to jointly resist the deviation of the insulation board 2.
[0024] The distance between the end of the obliquely inserted reinforcement 4 and the supporting formwork 7 is 10-20 mm. The end of the obliquely inserted reinforcement 4 should be away from the supporting formwork 7 to ensure that the wall surface is smooth and flat, and to avoid the obliquely inserted reinforcement 4 from fitting against the wall surface, which may cause the wall to crack easily.
