Description

Technical Field

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

[0002] The exterior wall infill wall can be constructed with point-connected composite insulation panels. The point-connected expanded perlite 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 connectors. According to the standard (GB50003-2011), the connection between the infill wall and the frame can be disconnected or not according to the design requirements. When there are seismic fortification requirements, it is advisable to disconnect the infill wall from the frame. Structural columns should be designed at the ends of the infill wall. 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 basis, 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 plate 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 problems existing in the above-mentioned prior art are that the reinforced concrete structure During the construction, structural columns made of structural materials require formwork support when pouring concrete. In addition to the increase in processes, the workload and cost will also increase. 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 leads to uncontrollable structural strength and quality. 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 opening structure of a point-connected expanded perlite composite insulation wall, construct a reinforced steel frame as the frame of the structural column and the horizontal tie beam, use EPS profiles as the core material of the structural column and the horizontal tie beam, and strengthen the adhesion of the plaster mortar and the insulation mortar by arranging a steel wire mesh. Under the premise of meeting the structural strength, the mortar adhesion can be conveniently achieved by spraying, the construction quality is controllable, the process is simple, and the construction cost is low.

[0004] The overall technical concept of the utility model is:

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

[0007] In order to facilitate the fixation of the EPS profile and the polystyrene board, a preferred implementation is that the outer edge of the EPS profile is bonded or integrated with the polystyrene board at the edge of the reserved hole on the point-connected composite insulation wall.

[0008] In order to facilitate the effective fixation of the steel wire mesh on the outer surface of the reinforced steel frame and the point-connected composite insulation wall, and thereby avoid local cracking of the mortar on the surface of the door and window openings or at the joints with the wall due to uneven force or thermal expansion and contraction, the preferred technical implementation method is to fix the steel wire mesh on the outer surface of the reinforced steel frame to the steel wire mesh on the point-connected composite insulation wall.

[0009] In order to effectively connect the steel mesh on the outer surface of the reinforced steel frame, the preferred technical implementation means is that the steel mesh fixed to the inner edge surface of the opening frame adopts a connecting mesh, and the two ends of the connecting mesh are respectively fixed to the steel mesh on the inner and outer sides of the EPS profile. Furthermore, the connecting mesh preferably adopts a U-shaped or L-shaped cross-sectional structure.

[0010] In order to improve the waterproof and crack-resistant properties of the surface of the plaster mortar layer and the thermal insulation mortar layer and meet the design and use requirements of durability, the preferred technical solution is that a waterproof and crack-resistant mortar layer is provided on the outer surface of the plaster mortar layer and / or the thermal insulation mortar layer.

[0011] In order to simplify the fixing operation of the transverse reinforcement and the longitudinal stress-bearing reinforcement and ensure that the strength of the structural column after forming meets the requirements, the preferred technical implementation means is that the transverse reinforcement and the longitudinal stress-bearing reinforcement are fixed by binding and / or welding to form a reinforced reinforcement frame.

[0012] The point-connected composite insulation wall preferably adopts the following structure, which includes a polystyrene board, an expanded perlite mortar layer fixed to the inner and outer surfaces of the polystyrene board, a steel mesh arranged at intervals on the outer surface of the expanded perlite mortar layer, and connectors that penetrate the point-connected composite insulation wall and are used to fix the steel mesh at both ends.

[0013] The technical progress achieved by the utility model is:

[0014] 1. The reinforced steel frame is used as the internal frame of the structural column and the horizontal tie beam, and the EPS profile and the structural design of the plaster mortar layer on the surface of the point-connected composite insulation wall are used. First, the flatness and structural strength requirements of the composite insulation wall and the opening frame surface after spraying mortar are effectively guaranteed, and the construction is convenient and the quality can be effectively controlled; second, because the thickness of the plaster mortar layer at the reinforced steel frame and the opening frame is greater than the plaster mortar layer at other parts, the structural design requirements of the frame reinforcement are cleverly met, the weight of the opening frame structure is reduced, and the overall load of the composite insulation wall is reduced; third, the precision requirements for the embedded reinforcement are low and it is easy to install, and the cost is reduced by about 50% compared with the existing structural columns of steel frames.

[0015] 2. The structural layer design uses steel wire mesh and is combined with a plaster mortar layer and an insulation mortar layer. First, the mortar layer on the opening frame and the wall surface can be laid by spraying, which reduces the process of using support formwork when forming existing reinforced concrete structural columns and horizontal tie beams, and eliminates the need for secondary acceptance procedures and sample block production. 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.

[0016] 3. The composite insulation wall and reinforced steel frame adopt a relatively independent structural design, which effectively improves the integrity and stability and enhances the seismic performance of the building structure.

[0017] 4. The structural design of the thermal insulation mortar layer can, firstly, block the thermal bridge effect of the opening frame and enhance the thermal insulation function of the building; secondly, it can effectively meet the requirements of fire protection regulations. The structural design of the waterproof and crack-resistant mortar layer can effectively enhance the waterproof function of the exterior wall. BRIEF DESCRIPTION OF THE DRAWINGS
