Description

Technical Field

[0001] This utility model relates to the field of building construction technology, specifically to an integrated prefabricated steel wire mesh frame cement insulation composite panel house structure. Background Technology

[0002] In the current construction field, traditional housing structures (such as reinforced concrete houses, container houses, and EPS foam houses) have many technical defects, making it difficult to meet the requirements of efficient construction, green environmental protection, and long-term use.

[0003] Cement-reinforced concrete houses require on-site manual labor for processes such as steel bar preparation, cutting, welding, tying, and placement. These processes are complex and rely heavily on manual skills, making it easy for steel bar design deviations to occur, leading to a decline in structural performance. Similarly, concrete preparation, mixing, and pouring also depend on manual operation. The water-cement ratio and sand-cement ratio are difficult to control precisely, and manual vibration is prone to under-vibration or over-vibration, resulting in honeycomb voids inside the concrete. Consequently, the concrete's durability, impermeability, and design mechanical properties all fail to meet standards.

[0004] Container houses are made entirely of steel plates, making them heavy and inconvenient to move. The assembly process relies on welding technology (butt welding, lap welding, and welding of key components), and all welding operations are done manually. The strength of the welded parts is inconsistent with that of the steel plate itself, making it impossible to form a truly integrated structure. Furthermore, the welded parts have a short service life and poor corrosion and acid / alkali resistance. They are neither environmentally friendly nor economical, and also waste state-owned resources.

[0005] EPS foam houses: These are assembled on-site using foam materials and require multiple complex processes such as adhesive bonding, adhesive fiber mesh application, board mounting, mesh hanging, and finishing. The technology is low and it is difficult to meet design requirements. The foam material has low impact resistance and cannot cope with the deformation caused by thermal expansion under natural weather conditions. Furthermore, the indoor air quality index does not meet green environmental protection standards.

[0006] Therefore, we urgently need to provide integrated prefabricated steel wire mesh frame cement insulation composite panel house structures. Utility Model Content

[0007] The purpose of this utility model is to provide an integrated prefabricated steel wire mesh frame cement insulation composite panel house structure to solve the problems mentioned in the background art.

[0008] To achieve the above objectives, this utility model provides the following technical solution: an integrated precast steel wire mesh frame cement insulation composite panel house structure, including a main frame, galvanized steel wire mesh frame, concrete, flame-retardant insulation board, L-shaped fixed angle iron inserts, T-shaped fixed angle iron inserts, straight fixed angle iron inserts, multi-specification fastening bolts, and pre-embedded plate holes. The main frame is composed of a1 plate, a1 groove, a plate, a groove, a3 plate, a3 groove, a4 groove, a4 plate, a5 plate, a5 groove, a6 plate, a6 groove, and a7 plate. The flame-retardant insulation board is composed of galvanized steel wire mesh, flame-retardant insulation board, and factory-precast commercial concrete layer. The composite board has pre-embedded plate holes that are compatible with the fastening bolts. The L-shaped, T-shaped, and straight fixed angle iron inserts are used to position the verticality and parallelism of adjacent composite boards. The fastening bolts pass through the pre-embedded plate holes to detachably fix the fixed angle iron inserts to the composite board.

[0009] A further improvement is that the mating sides of the flame-retardant insulation board are all cut at a 35-degree angle, forming a groove that matches the contour of the shaped angle iron plug after mating. The L-shaped groove corresponds to the L-shaped shaped angle iron plug, the T-shaped groove corresponds to the T-shaped shaped angle iron plug, and the straight groove corresponds to the straight shaped angle iron plug. The shaped angle iron plug is completely embedded in the groove, and both sides of the plug are tightly fitted and fixed to the pre-embedded plate holes of the corresponding composite board by fastening bolts.

[0010] A further improvement is that the upper and lower parts of the built-in flame-retardant insulation board of the galvanized steel wire mesh frame, as well as the butt joints of adjacent composite boards, are reserved with empty areas. The length, width and height of the empty areas are consistent with the beam and column dimensions of the house design, and a positioning steel mesh frame is set inside the empty areas. The empty areas are used to pour commercial concrete to form the beam and column structure of the house.

[0011] A further improvement is that the galvanized steel wire mesh frame in the built-in flame-retardant insulation board is reinforced with diagonal braces. The diagonal braces are welded to the inner side of the galvanized steel wire mesh frame in a crisscross pattern, and the material of the diagonal braces is the same as that of the galvanized steel wire mesh frame.

[0012] A further improvement is that the flame-retardant insulation board in the galvanized steel wire mesh frame is made of flame-retardant grade insulation material, and the factory-precast commercial concrete layer is a commercial concrete precast layer that meets the strength grade.

[0013] A further improvement is that the multi-specification fastening bolts include M-type and other models adapted to different composite plate connection positions, and the surface of all fastening bolts is treated with anti-corrosion.

[0014] A further improvement is that the main frame connection part is also pre-embedded plate holes, which are fixedly connected by fastening bolts, and the gap area of ​​the connection part is reinforced by pouring commercial concrete.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] This integrated precast steel wire mesh cement insulation composite panel house structure achieves true integration of house structure technology. The steel wire mesh is entirely manufactured in a factory, solving the problems of reduced design load-bearing capacity caused by technical defects in manual steel wire mesh fabrication, placement, and welding. Factory-cast commercial concrete pouring solves the problems of reduced design structural capacity caused by technical defects in manual operation, material batching, proportioning, and vibration, which lead to honeycomb voids. It also solves problems such as wall insulation, exterior wall design, paint, and inconvenience in transporting and installing large components. It saves a lot of manpower, material resources, and construction time, reduces cost waste, and is suitable for living and is green and environmentally friendly. Attached Figure Description

[0038] Working principle: Custom composite panels: Based on the design dimensions of residential buildings (e.g., exterior wall panel dimensions 2.4m × 1.2m, roof panel dimensions 3.6m × 2.4m), fire-retardant insulation panels are built into a steel wire mesh frame in the factory.

[0039] The galvanized steel wire mesh uses Φ4mm steel wire with a mesh spacing of 100mm×100mm and has built-in Φ6mm diagonal bracing (500mm longitudinal and transverse spacing).
