Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to a construction device for preventing cracking of residential insulated floors. Background Technology

[0002] With the advancement of technology and the improvement of living standards, people's requirements for the insulation level of their workplaces and living spaces are gradually increasing; as a shared part of adjacent floors, the insulation effect of floor slabs is closely related to people's work and life.

[0003] Currently, multiple walls and columns support the concrete floor. Due to the thermal expansion and contraction of concrete according to seasonal temperature, when the concrete expands and contracts, it presses against the wall and column when it reaches the edge of the wall and column. However, the concrete cannot move after pressing against the wall and column. Therefore, the concrete leveling layer is prone to forming hollow areas after rebounding under stress, which in turn leads to cracks at the connection between the wall and column and the floor. It can also strengthen the connection within the floor and prevent the floor from cracking.

[0004] Therefore, it is necessary to provide a new construction equipment for preventing cracking of residential insulated floors to solve the above-mentioned technical problems. Utility Model Content

[0005] The technical problem solved by this utility model is to provide a construction device for preventing cracking of residential insulated floors by providing an elastic space at the connection between the wall column and the floor, which can strengthen the internal connection of the floor and prevent the floor from cracking.

[0006] To solve the above-mentioned technical problems, the residential floor insulation anti-cracking construction equipment provided by this utility model includes: a lower layer of reinforcing mesh, which is laid on the surface of the floor, and the floor is poured on the surface of the floor; a positioning structure, which is placed on the floor, and includes a support column, a support leg, a stud, a washer, and a nut, the support leg being fixed to the side wall of the bottom end of the support column, the support column standing on the floor through the support leg, the stud being fixed to the top end of the support column, the washer being sleeved on the side wall of the stud, and the nut being threadedly connected to the top end of the stud; an upper layer of reinforcing mesh, which is erected on the top end of the support column; an extrusion structure, which is sleeved on the side wall of the support column; a restraining structure, which is backed against the inner side wall of the bottom end of the wall, and includes a restraining plate and a restraining groove, the restraining plate being backed against the inner side wall of the bottom end of the wall, and the restraining groove being located on the inner side wall of the bottom end of the restraining plate; and glass wool, which is adhered to the restraining groove.

[0007] Preferably, the width of the glass wool corresponds to the height of the limiting groove, and the thickness of the glass wool is greater than the depth of the limiting groove.

[0008] Preferably, the support column is square, and the cross-sectional area of ​​the support column is smaller than the through holes of the lower and upper steel meshes, and the length of the extended support leg is greater than the through hole of the lower steel mesh.

[0009] Preferably, the cross-sectional areas of the washer and the nut are both larger than the size of the through hole in the upper steel mesh, and the threaded connection between the nut and the stud cooperates with the washer to hold and fix the position of the upper steel mesh.

[0010] Preferably, the extrusion structure includes a collar and a baffle, the collar being slidably connected to the side wall of the support column, and the baffle being fixed to one end of the collar.

[0011] Preferably, the inner sidewall of the collar is square, corresponding to the sidewall of the support column, and the sidewall of the other end of the baffle abuts against the sidewall of the glass wool.

[0012] Compared with related technologies, the residential floor insulation crack prevention construction equipment provided by this utility model has the following beneficial effects:

[0013] This utility model provides a construction device for preventing cracking of residential floor insulation. First, a positioning structure is placed at each support position on the base plate, and a lower layer of reinforcing mesh is fitted onto the positioning structure, thus restricting the position of the positioning structure. Then, glass wool is cut to correspond to the dimensions of the restricting groove in the restricting structure, and the cut glass wool is attached to the side wall of the restricting structure. Next, the back of the restricting structure with the attached glass wool is pressed close to the wall, so that the restricting structure supports the glass wool attached to the inner side wall at the bottom of the wall. Finally, the extrusion structure is slid into the top of the positioning structure, and one end of the extrusion structure abuts against the restricting structure. On the inner wall of the structure, the extrusion structure supports and positions the restricting structure through the positioning structure. Then, the upper steel mesh is erected on the top of the positioning structure, and the production steel mesh is supported and fixed on the top of the positioning structure, so that the upper and lower steel meshes are parallel. Then, concrete is poured, and after solidification, the floor is formed. The upper and lower steel meshes strengthen the connection and structural strength within the floor, making the floor less prone to cracking. At the same time, the restricting structure is removed, creating a gap of the thickness of the restricting structure between the floor and the wall, so that the gap can accommodate the thermal expansion and contraction of the floor, thus preventing the floor from cracking.

[0023] In the specific implementation process, such as Figure 1 , Figure 5 and Figure 6 As shown, the width of the glass wool 6 corresponds to the height of the limiting groove 52, and the thickness of the glass wool 6 is greater than the depth of the limiting groove 52; the extrusion structure 9 includes a collar 91 and a baffle 92, the collar 91 is slidably connected to the side wall of the support column 41, and the baffle 92 is fixed to one end of the collar 91; the inner side wall of the collar 91 is square corresponding to the side wall of the support column 41, and the side wall of the other end of the baffle 92 abuts against the side wall of the glass wool 6, so that the position of the glass wool 6 can be restricted by the baffle 92 abutting against the glass wool 6, so that it can be tightly attached to the side wall of the limiting plate 51.

[0025] The working principle of the residential floor insulation crack prevention construction equipment provided by this utility model is as follows:

[0026] First, place the support column 41 at each support position on the floor 7 using the support legs 42, so that the outer support column 41 is close to the wall 8. Then, lay the lower layer steel mesh 1 on the base plate, and let the lower layer steel mesh 1 pass through the through holes of the support column 41, so that the lower layer steel mesh 1 is pressed against the support legs 42, thus restricting the position of the support column 41. Then, cut the glass wool 6 corresponding to the size of the restricting groove 52 and attach it to the restricting groove 52. Then, attach the restricting plate 51 close to the side wall of the wall 8, so that the glass wool 6 attached to the restricting groove 52 faces outward. Then, align one end of the baffle 92 with the wall 8, and slide the baffle 92 into the top of the support column 41 through the collar 91, so that the square side wall of the support column 41 restricts the position of the collar 91, thus restricting the position of the baffle 92. One end of the baffle 2 is parallel to the limiting plate 51, and the baffle 92 abuts against the side wall of the limiting plate 51 to restrict the position of the limiting plate 51. The glass wool 6 is squeezed and positioned in the limiting groove 52. Then, the washer 44 is put into the top of the stud 43, so that the washer 44 becomes the base for restricting the upper steel mesh 2. Then, the upper steel mesh is erected on the washer 44 through the through hole, and then threadedly connected to the stud 43 by the nut 45 to position the upper steel mesh 2 at the top of the support column 41. Then, concrete is poured and vibrated. After the concrete solidifies, the floor 3 is formed. Then, the limiting plate 51 is pulled out to form a certain gap between the floor 3 and the wall 8. The gap is then filled with glass wool to allow sufficient space for thermal expansion and contraction of the floor 3, thereby preventing the floor 3 from cracking.

[0027] Compared with related technologies, the residential floor insulation crack prevention construction equipment provided by this utility model has the following beneficial effects:

[0028] This utility model provides a construction device for preventing cracking of residential floor insulation. First, the positioning structure 4 is positioned at various support locations on the base plate, and the lower steel mesh 1 is fitted onto the positioning structure 4, thus restricting the position of the positioning structure 4. Then, the glass wool 6 is cut to correspond to the dimensions of the restricting groove 52 in the restricting structure 5, and the cut glass wool 6 is attached to the side wall of the restricting structure 5. Next, the back of the restricting structure 5 with the attached glass wool 6 is pressed close to the wall 8, so that the restricting structure 5 supports the glass wool 6 attached to the inner side wall of the bottom end of the wall 8. Then, the extrusion structure 9 is slid into the top of the positioning structure 4, and one end of the extrusion structure 9 abuts against the restricting structure 4. On the inner wall of structure 5, the extrusion structure 9 supports and positions the restriction structure 5 through the positioning structure 4. Then, the upper steel mesh 2 is erected at the top of the positioning structure 4, so that the production steel mesh is supported and fixed at the top of the positioning structure 4, making the upper steel mesh 2 and the lower steel mesh 1 parallel. Then, concrete is poured, and after solidification, the floor 3 is formed. The upper steel mesh 2 and the lower steel mesh 1 strengthen the connection and structural strength within the floor 3, making the floor 3 less prone to cracking. At the same time, the restriction structure 5 is removed, so that a gap of the thickness of the restriction structure 5 is formed between the floor 3 and the wall 8, so that the gap can meet the range of thermal expansion and contraction of the floor 3, thereby preventing the floor 3 from cracking.
