Description

Technical Field

[0001] The utility model belongs to a door and window frame connection structure in the field of construction, in particular to a door and window frame connection structure of a point-connected expanded perlite composite thermal insulation wall. Background Art

[0002] The exterior wall filling wall can be constructed with point-connected composite insulation panels. The point-connected composite insulation panels use polystyrene boards with expanded perlite mortar attached to the surface as the core material, and the steel mesh set at intervals on the surface of the core material is fixed by connecting parts. According to the requirements, structural columns should be designed at the ends of the filling walls. The structural column structure of the door and window openings of the point-connected non-bearing composite insulation wall includes the following two methods: one is to use the pre-embedded reinforcement of the floor slab as the connection foundation, and to construct structural columns and horizontal tie beams made of reinforced concrete structural materials on the composite insulation wall panels; the other is to use the pre-embedded steel plates of the floor slab as the basis, and to anchor the structural columns and horizontal tie beams made of steel frames on the pre-embedded steel plates. The two structural forms of structural columns and horizontal tie beams have sufficient structural strength and a stable installation foundation, so they can be directly used to fix door and window frames. The above-mentioned existing technologies have the following problems: one is that the structural columns made of reinforced concrete structural materials are During the construction, concrete pouring requires formwork support, which will increase the workload and cost based on the increase in processes; due to the existence of the formwork, the density of the horizontal tie beam cannot be guaranteed to meet the requirements when pouring concrete, which makes its structural strength and quality uncontrollable; secondly, although the steel frame is simple to form and install, and the strength can meet the requirements, based on the anchoring requirements, the embedded parts should use embedded steel plates and the embedding accuracy requirements are high. In addition, due to the high cost of the structure, it has been abandoned by most construction companies in practice due to the current status of construction contracting projects and the actual need to strictly control construction costs. Summary of the invention

[0003] The purpose of the utility model is to provide a door and window frame connection structure of a point-connected expanded perlite composite insulation wall, construct a structural column and a horizontal tie beam with sufficient structural strength and easy to monitor the construction quality as an installation basis for the door and window frames, and by arranging embedded parts stably connected to the installation basis as a connection medium with the door and window frames, the door and window frame connection structure can be integrated with the door and window openings under the condition of effectively reducing construction costs and controlling quality, and the construction is fast and the process is simple.

[0006] The specific technical solutions of the utility model also include:

[0007] The main function of the embedded parts is to facilitate the connection with the door and window frames. In order to improve the connection strength with the wire mesh and meet the installation requirements of the door and window frames, the preferred technical implementation method is that the embedded parts adopt one of the straight, L-shaped, and U-shaped structures or a combination of them. In order to improve the structural strength of the embedded parts and the bonding strength with the mortar layer, the embedded parts are made of steel.

The structural design is convenient for the rapid fixation of the embedded parts and the steel mesh, thereby meeting the need for fast construction; secondly, the working part is convenient for installation with the door and window frames. Since the sprayed mortar layer is thick, the dust on the surface of the working part can be easily knocked off by tools, so that the working part is exposed, adapted to the door and window frames, and quickly installed.

[0017] 2. The embedded parts adopt a straight, L-shaped or U-shaped structural design. First, it can be easily tied and fixed with the wire mesh in different parts according to needs; second, the corresponding structural design can be adopted according to the needs of the adapted door and window frames, which has better adaptability; third, it effectively increases the contact area with the door and window frames, making its connection with the door and window frames more reliable.

[0018] 3. The embedded parts and the wire mesh are fixed by binding and the structure design of the bayonet is convenient for rapid assembly with the wire mesh, thereby increasing the construction speed; secondly, it is convenient to improve the positioning reliability of the embedded parts and the mesh.

[0019] 4. The structural columns and horizontal tie beams adopt a structural design from the inside to the outside with EPS profiles as the core material, reinforced steel frame, wire mesh, and mortar layer; first, it cleverly meets the structural design requirements of frame reinforcement, reduces the structural weight of door and window openings, and reduces the overall load of the composite insulation wall; second, it effectively guarantees the flatness requirements of the composite insulation wall and door and window openings after spraying mortar on the surface, which is convenient for construction and the quality can be effectively controlled; third, the accuracy requirements for embedded reinforcement are low, and the cost is reduced by about 50% compared with the existing structural columns of steel frames.

[0020] 5. The structural design of the insulation mortar layer and the plaster mortar layer, firstly, blocks the thermal bridge effect of door and window openings, enhances the insulation function of the building and effectively meets the requirements of fire protection regulations; secondly, it cooperates with the structure of the reinforced steel frame to effectively improve the structural strength of the structural columns and horizontal tie beams.

[0021] 6. The structure of the steel wire mesh is combined with the structural layer design of the plaster mortar layer and the thermal insulation mortar layer. First, the mortar layer can be constructed by spraying, which reduces the process of pouring concrete with supporting formwork when forming the door and window openings of the existing composite thermal insulation wall, as well as the secondary acceptance process and sample block production brought about by this. The manufacturing process is simple, the construction cost is low and the quality is easy to control. Second, the steel wire mesh can effectively improve the adhesion to the mortar, and at the same time, it can transfer the force to the embedded reinforcement by strengthening the steel frame, effectively avoiding stress concentration.
