Description

Technical Field

[0001] The invention belongs to the technical field of lightweight partition wall construction in building engineering, and in particular relates to a composite wall door and window opening structure and a composite wall door and window installation method. Background Art

[0002] With the progress of building industrialization, various new wall materials have been increasingly applied to buildings. Foamed ceramic lightweight partition boards have been widely used in wall materials due to their advantages of light weight, small drying shrinkage, and fast construction and installation. The sandwich-structured foamed ceramic composite wallboard, which consists of two foamed ceramic boards wrapped with cement polystyrene particles, has a smaller bulk density and better thermal insulation performance. It is also used as a new wall material in building partitions to form a foamed ceramic polystyrene particle composite wall.

[0003] The foamed ceramic polystyrene particle composite wall has polystyrene particle material in the middle. When the expansion bolts used to install doors (windows) are driven into the polystyrene particle interlayer of the foamed ceramic polystyrene particle composite wall, the low strength of the polystyrene particles causes the doors (windows) to be unstable after installation and are prone to loosening. Traditionally, reinforced concrete structural columns are often added on both sides of the door (window) openings. This method of adding reinforced concrete structural columns is labor-intensive and requires multiple processes such as planting steel bars, tying steel bars, supporting formwork, and pouring concrete. In addition, the structural column construction is prone to mold explosion, resulting in inconsistency between the width of the structural column and the lightweight partition wall. In addition, the junction between the structural column and the foamed ceramic polystyrene particle composite wall is prone to cracking after plastering and decorative painting due to the inconsistent drying shrinkage values ​​of the two materials. Summary of the invention

[0004] In view of this, an object of the present invention is to provide a composite wall door and window opening structure to solve the technical problems in the prior art that when installing doors and windows in a composite wall, reinforced concrete structural columns need to be added on both sides of the door and window openings, resulting in cumbersome construction and difficulty in ensuring construction quality; an object of the present invention is also to provide an installation method for composite wall doors and windows.

[0005] To achieve the above purpose, the technical solution adopted by the present invention is:

[0006] A composite wall door and window opening structure, comprising:

[0007] The foamed ceramic polystyrene particle composite wallboard is formed by the inner foamed ceramic board, the outer foamed ceramic board and the cement polystyrene particle board. The cement polystyrene particle board is located between the inner foamed ceramic board and the outer foamed ceramic board and is connected with the inner and outer foamed ceramic boards. The foamed ceramic polystyrene particle composite wallboard is provided with installation holes for installing doors and windows. The cement polystyrene particle board is provided with installation holes on two side walls opposite to the installation holes.

[0008] A connection block, corresponding to the mounting holes one by one, the connection block being formed by filling the mounting holes with a gelling material filler;

[0009] The door and window frame is placed at the installation opening and connected to the corresponding connection block through expansion bolts. The gap between the edge of the door and window frame and the cement polystyrene particle board is filled with cement mortar for sealing, and the space between the inside of the door and window frame and the cement polystyrene particle board is filled with concrete grouting material.

[0010] The beneficial effect of the above technical solution is that when installing the door and window frames, the present invention does not directly drive the expansion bolts into the cement polystyrene particle board, but instead digs out an installation hole in the cement polystyrene particle board at the position where the door and window frame is installed, and fills the installation hole with cementitious material to condense into a connecting block. The connecting block can ensure the bonding strength between the inner foamed ceramic board and the outer foamed ceramic board on the one hand, and can be used for expansion bolts to be driven in to fix the door and window frames on the other hand. Under the closing effect of cement mortar and the filling effect of concrete grouting material, the doors and windows are ensured to be installed securely and the looseness of the doors and windows is reduced. The composite wall door and window opening structure of the present invention does not need to add reinforced concrete structural columns on both sides of the door and window installation openings, and the structure is simpler, and the construction workload is small, the construction is more convenient, the construction materials used are small, and the cost is lower. At the same time, cracks caused by drying shrinkage at the junction of different materials in the door and window openings are also avoided.

[0011] Furthermore, the installation hole passes through the cement polystyrene particle board.

[0012] Beneficial effects: The thickness of the connection block can be guaranteed, so that the expansion bolts can be completely driven into the connection block, and the expansion bolts will not pass through the connection block into the cement polystyrene particle board, thus avoiding the loosening of the door and window frames after installation; at the same time, it also increases the bonding area between the cementitious material and the inner and outer foamed ceramic panels, thus ensuring the strength of the wall.

[0013] Furthermore, there are more than two mounting holes spaced apart from top to bottom along the height direction of the mounting hole.

[0014] Beneficial effect: more fixing points of door and window frames are provided, thereby ensuring that the door and window frames are firmly fixed.

[0015] Furthermore, the mounting hole is a rectangular hole.

[0016] Beneficial effects: The rectangular hole is easy to open and the construction is convenient.

[0017] Furthermore, the gelling material is cement.

[0018] Beneficial effects: Cement can have higher strength in a shorter curing time, which is conducive to quickly achieving the combination between it and the inner and outer foamed ceramic panels, and when the expansion bolts are driven into the cement, they can be firmly fixed.

[0019] The technical solution of the installation method of the composite wall door and window of the present invention is:

[0020] The installation method of the composite wall door and window comprises the following steps:

[0021] S1. According to the construction drawing, pop up the wall position line on the main structure floor and mark the door and window installation opening positions;

[0022] S2. Install the foamed ceramic polystyrene particle composite wall according to the detailed design drawings, and leave holes for door and window installation according to the detailed design drawings;

[0023] S3. At the location of the door and window installation opening, mark the corresponding position of the expansion bolts when the pre-installed door and window frame is installed on the wall, and mark it with a marker;

[0024] S4. At the position marked by the marker pen, use a cutter to hollow out the polystyrene particles in the middle of the foamed ceramic polystyrene particle composite wall, and the hollowed-out shape is a rectangle;

[0025] S5, mix a cementitious material for filling the hole, fill it with a spatula, fill the rectangular hole dug out in step S4, and allow it to naturally cure for 7 days to form a strong door and window installation connection block;

[0026] S6. Align the installation expansion bolts of the door and window frames with the middle of the corresponding connection blocks at the door and window installation openings. After fine-tuning the verticality and installation angle of the door and window frames, temporarily fix the door and window frames. Then drive the expansion bolts into the connection blocks from the installation holes on the door and window frames and tighten the expansion bolts.

[0027] S7. Use cement mortar to fill the gap between the door and window frames and the foamed ceramic polystyrene particle composite wall, and smooth it to a square shape;

[0028] S8. Finally, use concrete grouting to fill the door and window frames, and install the door leaves after the strength reaches the requirement.

[0029] Furthermore, the cementitious material for filling the holes in step S5 is cement.

[0030] The beneficial effect of the above technical scheme is that when installing the door and window frames, the present invention does not directly drive the expansion bolts into the cement polystyrene particle board, but instead digs out a rectangular hole in the cement polystyrene particle board at the position where the door and window frames are installed, and fills the rectangular hole with cementitious material to condense into a connecting block. The connecting block can ensure the bonding strength between the inner foamed ceramic board and the outer foamed ceramic board on the one hand, and can be used for the expansion bolts to be driven in to fix the door and window frames on the other hand. Under the closing effect of cement mortar and the filling effect of concrete grouting material, the doors and windows are ensured to be installed securely and the looseness of the doors and windows is reduced. The foamed ceramic polystyrene particle composite wall door and window installation method of the present invention does not need to add reinforced concrete structural columns on both sides of the door and window installation holes, and the structure is simpler, and the construction workload is small, the construction is more convenient, the construction materials used are small, and the cost is lower. At the same time, cracks caused by drying shrinkage at the intersection of different materials in the door and window holes are also avoided. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0039] The present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0040] like Figures 1 to 6 As shown, the composite wall door and window opening structure includes a foamed ceramic polystyrene particle composite wallboard 1, a connecting block and a door and window frame.

[0041] like Figure 1 As shown, the foamed ceramic polystyrene particle composite wallboard 1 is formed by a composite of a foamed ceramic board 3 and a cement polystyrene particle board 4. The foamed ceramic board 3 includes an inner foamed ceramic board and an outer foamed ceramic board. The cement polystyrene particle board 4 is located between the inner foamed ceramic board and the outer foamed ceramic board, and is connected to the inner and outer foamed ceramic boards. The foamed ceramic polystyrene particle composite wallboard 1 is provided with an installation hole 2 for installing doors and windows. The installation hole 2 is in an inverted U shape. Figure 2 As shown, the cement polystyrene particle board 4 is provided with mounting holes 5 on two side walls opposite to the mounting hole 2, and the number of mounting holes 5 on each side wall is three, and the three mounting holes 5 are arranged from top to bottom along the height direction of the mounting hole 2. In this embodiment, each mounting hole 5 is a rectangular hole and passes through the cement polystyrene particle board 4 to form a hollow hole of the cement polystyrene particle board.

[0042] like Figure 3 As shown, each mounting hole 5 is filled with a gelling material filler, which solidifies to form a high-strength connecting block 6. In this embodiment, the gelling material filler is cement, which has high strength after solidification and has high reliability in combination with the inner foamed ceramic plate and the outer foamed ceramic plate.

[0043] like Figure 4 As shown, the door and window frame 7 is placed at the installation opening 2, and expansion bolt installation holes 9 are arranged at positions corresponding to the installation holes 5 on the door and window frame 7, and the door and window frame 7 is connected to the corresponding connection block 6 through expansion bolts 8 passing through the corresponding expansion bolt installation holes 9. Figure 5 As shown, after adjusting the installation angle of the door and window frame 7 and fixing the door and window frame 7 with expansion bolts 8, the gap between the edge of the door and window frame 7 and the cement polystyrene particle board 4 is filled with cement mortar 10 to close the gap and then smoothed to make it square. Figure 6 As shown, the space inside the door and window frame 7 and between the cement polystyrene particle board 4 is filled with concrete grouting material 11, and the door and window can be installed after the concrete grouting material 11 reaches the strength requirement.

[0044] When installing the door and window frame 7, the present invention does not directly drive the expansion bolt 8 into the cement polystyrene particle board 4, but instead hollows out a mounting hole 5 in the cement polystyrene particle board 4 at the position where the door and window frame is installed, and fills the mounting hole 5 with cementitious material to solidify into a connecting block 6. The connecting block 6 can ensure the bonding strength between the inner foamed ceramic board and the outer foamed ceramic board on the one hand, and can provide the expansion bolt 8 for driving into to fix the door and window frame 7 on the other hand. Under the closing effect of the cement mortar 10 and the filling effect of the concrete grouting material 11, the door and window are securely installed and the looseness of the door and window is reduced.
