Description

Technical Field

[0001] The utility model belongs to the technical field of building plastering construction, in particular to a device for controlling hollowing cracks in plastering at the junction of walls. Background Art

[0002] In recent years, with the continuous development of my country's construction industry, the volume of buildings and structures has continued to increase, and the number of high-rise buildings built in various cities has increased day by day, resulting in a huge amount of indoor wall plastering. At present, the building materials mostly used for indoor secondary structure walls are autoclaved aerated concrete blocks, ALC wall panels or autoclaved ceramsite concrete wall panels. The junction of different secondary structure wall materials and the main structure reinforced concrete wall is a frequent area for plaster hollowing. A large number of hollows increase the amount of maintenance and rework, waste resources, increase the cost unnecessarily, and seriously affect the construction period. In addition, the repaired plastering will produce obvious patch marks, which also has a great impact on the overall appearance of the building. For this reason, it is necessary to increase the control of the plaster hollowing rate at the junction of different materials. Utility Model Content

[0003] The technical problem to be solved by the utility model is to provide a device for controlling hollowing and cracks in plastering at the junction of walls, so as to reduce the defective rate of hollowing and bulging at the junction of different materials.

[0004] The technical solution adopted by the utility model to solve its technical problems is: to provide a device for controlling hollow cracks in plaster at the junction of walls, including a wall hook pre-buried at the junction of a main wall panel and a secondary structure wall panel, and also including a disc simultaneously clamped on the sides of the main wall panel and the secondary structure wall panel, a nail plate connecting device is installed between the wall hooks arranged opposite to each other, a middle section of the nail plate connecting device is provided with a nail plate hook extending to both sides, the disc is fixed at the end of the nail plate hook, the diameter of the disc is larger than the spacing at the junction of the main wall panel and the secondary structure wall panel, and the junction of the main wall panel and the secondary structure wall panel is filled with mortar.

[0005] Preferably, the wall hooks are pre-buried in the main wall panels and the secondary structure wall panels through wall fixing buckles.

[0006] Preferably, a plurality of the wall hooks are arranged at intervals along the height direction on the main wall panels and the secondary structure wall panels.

[0007] Preferably, a mesh cloth is embedded on the outside of the disc through mortar.

[0008] Preferably, a plurality of through holes are opened on the surface of the disc.

[0009] Beneficial Effects

[0010] The utility model utilizes new components, which greatly reduces the hollowing rate at the junction of different materials, ensures the first-time acceptance rate, reduces secondary hollowing caused by vibration generated by chiseling hollow parts, avoids hollowing in other parts due to adverse factors such as temperature and humidity after chiseling, and reduces maintenance costs. The utility model only needs to be pre-buried in advance at the location where materials such as masonry or ceramsite boards are connected to the shear wall and the spacing is reasonably controlled. The installation is simple and the use is effective. The utility model can greatly reduce the probability of hollowing at the junction of different materials, avoid rework, reduce maintenance costs, improve the first-time acceptance rate, and can also reduce hollowing caused by the passage of time, ensuring the construction quality. Good social and economic benefits are achieved. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The utility model provides a device for controlling hollow cracks in plaster at the junction of walls, including a wall hook 2 embedded in the junction of a main wall panel 6 and a secondary structure wall panel 7, and a disc 4 simultaneously clamped on the sides of the main wall panel 6 and the secondary structure wall panel 7, and a nail plate connecting device 3 is installed between the wall hooks 2 arranged opposite to each other. The nail plate connecting device 3 is a long board, and a nail plate hook 5 extending to both sides is provided in the middle section. The disc 4 is fixed at the end of the nail plate hook 5, and the diameter of the disc 4 is larger than the spacing at the junction of the main wall panel 6 and the secondary structure wall panel 7, and the junction of the main wall panel 6 and the secondary structure wall panel 7 is filled with mortar 8.

[0020] like Figures 1-2 As shown, in a specific embodiment, the main wall panel 6 refers to a concrete wall, that is, a main structural reinforced concrete wall, and the secondary structure wall panel 7 is a ceramsite board wall. In other embodiments, it can also be an autoclaved aerated concrete block, ALC wall panel, etc.

[0021] The wall hook 2 is embedded in the main wall panel 6 and the secondary structure wall panel 7 through the wall fixing buckle 1. In addition to being embedded, the wall fixing buckle 1 can also be fixed to the wall panel surface by strong glue. The nail plate hook 5 is arranged obliquely downward, and the opposite wall hook 2 is arranged obliquely upward.

[0022] Figure 3 As a schematic diagram, after the main wall panel 6 and the secondary structure wall panel 7 are controlled to have a spacing of less than 2 cm, the nail plate hook 5 can be matched and connected with the wall hook 2. The main wall panel 6 and the secondary structure wall panel 7 are provided with a plurality of wall hooks 2 spaced apart in the height direction, and the spacing is 20 to 30 cm.

[0023] A mesh cloth 9 is embedded on the outside of the disc 4 through the mortar 8. The width of the mesh cloth 9 is greater than the diameter of the disc 4, and the mesh cloth 9 further disperses the shrinkage stress of the mortar 8 to the entire flexible surface.

[0024] The surface of the disk 4 is provided with a plurality of through holes, such as Figure 4 As shown, the through holes are arranged in a petal shape around the circumference of the disc 4, so that the disc 4 can be completely covered when the mortar 8 is filled. Figure 5 As shown, the back of the circular disc 4 is provided with a mounting groove matching the nail plate hook 5, which can be hooked on the nail plate hook 5 of the nail plate connecting device 3. The surface of the circular disc 4 is also provided with reinforcing ribs. In a specific embodiment, the reinforcing ribs are cross-shaped.

[0030] 2) Install the nail plate connecting device 3 at the wall hook 2 installed in advance on the cast-in-place concrete wall and the ceramsite board, and the installation groove of the nail plate connecting device 3 is effectively connected with the hook buckled on the wall;

[0031] 3) After the nail plate connection device 3 is effectively connected to the wall hook 2, the ceramsite board and the cast-in-place concrete wall are installed and calibrated.

[0032] Step 3: gap filling;

[0033] 1) Mix the mortar 8 prepared previously on site according to the proportion;

[0034] 2) After the position of the wall panel is corrected, the prepared mortar 8 is used to fill the gap between the ceramsite board and the cast-in-place concrete wall panel.

[0035] Step 4: Anchoring treatment

[0036] 1) After the mortar 8 is effectively filled and the mortar 8 has a certain strength but has not yet completely hardened, the prepared disc 4 is installed on the connecting device of the nail disc;

[0037] 2) The discs 4 on both sides are effectively connected by the nail plate connecting device 3, and the two discs 4 cooperate with the nail plate connecting device 3 to firmly clamp the wall panel;

[0038] 3) Then, the gap between the ceramsite board and the cast-in-place concrete wallboard is reinforced with a mesh cloth 9 to provide a better connection between the disc 4 and the wall surface.

[0039] The utility model uses the nail plate connecting device 3 to better connect the ceramsite board and the cast-in-place concrete board, so that the connection between different materials is tighter, and then the disk 4 and the mesh cloth 9 are strengthened to better connect the two together, reducing the possibility of cracks here.
