Assembly type convenient-to-install composite structural slab

Abstract

The invention belongs to the technical field of building materials, and discloses an assembly type convenient-to-install composite structural slab. The slab includes an inner frame which is shaped bya cold-formed steel strip, the inner frame is filled with cementitious materials, the side edges of the inner frame are provided several first connection holes, one side edge of the inner frame is provided with a connection convex block, and the other side edge of the inner frame is provided with a connection groove. The connection convex block and the connection groove are both provided with elongated slots in which waterproof rubber belts are placed, and the first connection holes are provided with reserved holes facilitating the installation of fasteners. The slab can overcome the shortcoming of insufficient compactness between common wallboards and can meet the rigid requirements of the waterproof quality, the heat preservation quality and the like in construction engineering. Meanwhile, the problem of joint connection between assembly slabs is effectively solved, the solid waste material application technology is adopted for slab forming, and environmental hazards caused by solidwaste can be effectively reduced.

Description

technical field [0001] The invention belongs to the technical field of building materials, and in particular relates to an assembly-type conveniently installed composite structure board. Background technique [0002] Existing buildings generally use prefabricated structural wall panels or cast-in-place structural panels for wall construction. During the use of prefabricated structural wall panels, there will be gaps due to no reliable connection between panels. When the building subsides or is affected by wind pressure and vibration, it will cause cracks and water leakage in the walls and floors, and it is not allowed to build partition walls on the floor according to the requirements of the households, otherwise the floor will be damaged due to uneven force between the wall panels. collapsed. For the improvement of modern construction quality requirements and building body requirements, ordinary unconnected assembled slats have many disadvantages. For cast-in-place struct...

Problems solved by technology

[0006] Beneficial effects: the cold-formed steel strip can be designed and shaped according to actual needs, and does not need to be manufactured according to the manufacturing form of the cast-in-place plate; after the cold-formed steel strip is formed, cement or other cementitious materials can be directly poured into the hollow part; the invention can The problem of the tightness of the connection between the prefabricated boards is solved through the first connection hole, so that the building has good waterproof and heat preservation performance while maintaining the impact resistance and earthquake resistance; through the reserved holes, the prefabricated boards are solved. Difficult to connect between the two bodies, and poor connection performance, so that the prefabricated boards have good stability; the setting of the connection groove and the connection bump can ensure the accurate connection between the structural boards, reducing the number of two boards. The connection error between the boards; multiple rubber strips are placed at the joint between the boards to avoid water seepage in the wall, and the boards are connected by high-strength bolts. Balanced elasticity, the board and the board are not affected by temperature difference deformation, micro-vibration, uneven settlement of the main structure, etc., so that the quality of the board structure is stable, ensuring that the invention can obtain better quality stability during use; the invention sets The long groove can better achieve waterproof, sound insulation and other effects; the setting of the reserved hole can make it convenient for the operator to insert the connecting fastener into the first connecting hole for fastening, so that the two inner frames can be well connection, and it is also convenient for the operator to take out the connecting fasteners in the first connecting hole
