Description

Technical Field

[0001] The utility model belongs to the technical field of construction, and in particular relates to a flat mesh self-distanced steel bar grid sandwich insulation board prefabricated component. Background Art

[0002] Current insulation panels are usually prefabricated components, that is, they are pre-produced in the factory and then transported to the construction site. After the insulation panels are spliced on site to form a wall cavity, the cavity is poured to form a complete wall structure.

[0003] When constructing the wall cavity, it is not only necessary to ensure that the steel grid and the insulation board are parallel, but also the inner cavity spacing of the wall cavity needs to be adjusted to meet the designed wall thickness. This results in a large number of prefabricated component models, which increases the difficulty of prefabrication. In addition, the construction site needs to be managed more strictly to avoid misuse, which increases the difficulty of construction. Utility Model Content

[0004] In order to solve the problems existing in the above-mentioned prior art, the utility model provides a flat mesh self-spacing steel grid sandwich insulation board prefabricated component, which adjusts the distance between the insulation board and the steel grid by the positioning groove and the misalignment between the positioning grids, thereby meeting the design requirements of different wall thicknesses. The factory only needs to produce a single model of prefabricated components, which reduces management difficulty and avoids misuse in assembly at the construction site.

[0005] The specific technical solution adopted in this utility model is:

[0006] A flat mesh self-spacing steel grid sandwich insulation board prefabricated component includes multiple groups of prefabricated units connected end to end, the prefabricated units include insulation boards and steel grids, and positioning grooves and positioning grids with concave-convex matching are provided between the insulation boards and the steel grids. The positioning grooves are fixedly connected to the insulation boards, and the positioning grids are fixedly connected to the steel grids. The steel grids are connected to the insulation boards by means of the matching positioning grooves and positioning grids. The upper prefabricated units and the lower prefabricated units are arranged adjacent to each other up and down and are connected by means of binding between adjacent positioning grids.

[0007] The insulation board includes an insulation layer, a supporting grid and a casting layer. The casting layer faces the side of the positioning groove. A wavy steel mesh structure is connected to the supporting grid. The groove of the steel mesh structure is formed into a positioning groove. The trough of the steel mesh structure passes through the casting layer and is connected to the supporting grid. The positioning groove is bonded and fixed to the insulation board with the help of the casting layer.

[0008] The positioning grooves are in a V-shaped groove structure, a plurality of rows of positioning grooves are arranged at intervals in the vertical direction on the insulation board, and the positioning grid is in a V-shaped mesh structure matching the positioning grooves.

[0009] The V-shaped structure of the positioning grid comprises a fixed side that fits the diagonal side of the positioning groove and a hanging side on the other side. The fixed side of the positioning grid has the freedom to adjust the distance along the diagonal side of the positioning groove.

[0010] The positioning groove is provided with a distance nut, and multiple groups of the distance nuts are arranged at equal intervals along the diagonal side of the positioning groove. The fixed side of the positioning grid is provided with a fixing nut, and the positioning grid is fixedly connected to the positioning groove by means of bolts passing through the distance nuts and the fixing nuts.

[0011] The positioning grid is further provided with a connecting grid, the two ends of which are respectively tied and fixed to the hanging side and the positioning slot of the positioning grid, and the hanging side and the positioning slot are connected to form a whole by means of the connecting grid.

[0012] The V-shaped angle of the positioning grid is smaller than the V-shaped angle of the positioning groove. The gap between the positioning grid and the positioning groove forms a filling cavity. The positioning grid is fixedly connected to the positioning groove by means of cast-in-place concrete poured into the filling cavity.

[0013] The beneficial effects of the utility model are:

[0014] 1. In this embodiment, positioning grooves and positioning grids are additionally provided. The insulation board and the steel grid are processed and formed in the factory. At the construction site, the insulation board and the steel grid are first matched with the help of the positioning grooves and the positioning grids. Then, the spacing between the insulation board and the steel grid is adjusted by the misalignment between the positioning grooves and the positioning grids, thereby meeting the design requirements of different wall thicknesses. The factory only needs to produce a single model of prefabricated components, which reduces management difficulty and avoids assembly errors at the construction site.

[0015] 2. The positioning groove and positioning grid in the utility model play a positioning role. When the positioning groove and the positioning grid are matched, it can ensure that the insulation board and the steel grid are necessarily parallel. There is no need to use a level and a plumb line to measure and adjust the positional relationship between the insulation board and the steel grid at the construction site, thereby ensuring the construction quality.

DETAILED DESCRIPTION

[0020] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0021] Specific embodiment 1, as shown in the figure, this specific embodiment provides a flat mesh self-spacing steel grid 2 sandwich insulation board 1 prefabricated component, including multiple groups of prefabricated units connected end to end, the prefabricated unit includes an insulation board 1 and a steel grid 2, and a concave-convex positioning groove 3 and a positioning grid 4 are provided between the insulation board 1 and the steel grid 2. The positioning groove 3 is fixedly connected to the insulation board 1, and the positioning grid 4 is fixedly connected to the steel grid 2. The steel grid 2 is connected to the insulation board 1 by means of the matching of the positioning groove 3 and the positioning grid 4. The upper prefabricated unit and the lower prefabricated unit are arranged adjacent to each other along the upper and lower sides and are connected by means of binding between adjacent positioning grids 4.

[0022] When constructing the wall cavity, it is not only necessary to ensure that the steel grid 2 is parallel to the insulation board 1, but also the inner cavity spacing of the wall cavity needs to be adjusted to meet the designed wall thickness, resulting in a large number of prefabricated component models, increasing the difficulty of prefabrication, and the construction site needs to be strengthened in management to avoid misuse, which increases the difficulty of construction.

[0023] Therefore, in this embodiment, positioning grooves 3 and positioning grids 4 are additionally provided, and the insulation board 1 and the steel grid 2 are processed and formed in the factory. At the construction site, the insulation board 1 and the steel grid 2 are first matched with the help of the positioning grooves 3 and the positioning grid 4, and then the distance between the insulation board 1 and the steel grid 2 is adjusted by the misalignment between the positioning grooves 3 and the positioning grid 4 (the distance between the insulation board 1 and the steel grid 2 is the thickness of the wall cavity), so as to meet the design requirements of different wall thicknesses, and the factory can produce prefabricated components of a single model.

[0024] Secondly, the positioning groove 3 and the positioning grid 4 play a positioning role. When the positioning groove 3 and the positioning grid 4 are matched, it can be ensured that the insulation board 1 and the steel grid 2 are necessarily parallel. There is no need to use a level and a plumb line to perform a large number of measurements and adjustments on the positional relationship between the insulation board 1 and the steel grid 2 at the construction site, thereby ensuring the construction quality.

[0025] In addition, the width of the prefabricated unit is relatively short, which is convenient for production and transportation. When splicing on site, it is only necessary to tie the steel mesh frame 2, and the splicing process is convenient and simple.

[0026] The insulation board 1 includes an insulation layer 101, a support grid 102 and a casting layer 103. The casting layer 103 faces one side of the positioning groove 3. A wavy steel mesh structure is connected to the support grid 102. The grooves of the steel mesh structure form the positioning grooves 3. The troughs of the steel mesh structure pass through the casting layer 103 and are connected to the support grid 102. The positioning grooves 3 are bonded and fixed to the insulation board 1 with the help of the casting layer 103. In order to achieve a fixed connection between the insulation board 1 and the positioning grooves 3, the insulation board 1 in the present invention is a three-layer sandwich structure. During factory prefabrication, the positioning grooves 3 are first tied or welded to one side of the support grid. Then, the other side of the support grid 102 is laid on the surface of the insulation layer 101. Then, concrete is poured on one side of the support grid 102 to form the casting layer 103. The casting layer 103 is used to integrate the support grid 102 and the insulation layer 101, thereby achieving a fixed connection between the insulation board 1 and the positioning grooves 3. At the same time, the end of the positioning groove 3 extends along the insulation layer 101 and is inserted into the insulation layer 101, so that the positioning groove 3 and the insulation layer 101 form a plug-in fit, which improves the structural strength of the insulation layer 101 and increases the connection integrity between the insulation layer 101 and the positioning groove 3.

[0027] The positioning grooves 3 are V-shaped, with multiple rows of positioning grooves 3 arranged vertically on the insulation board 1. The positioning grid 4 is a V-shaped mesh structure that matches the positioning grooves 3. In the first embodiment, the included angle of the positioning grooves 3 is equal to the included angle of the positioning grid 4. Compared to the concave and convex fit of a bow-shaped structure, the tip of the V-shaped positioning grid 4 is more easily aligned with the opening of the positioning groove 3, making assembly easier during construction.

[0028] The V-shaped structure of the positioning grid 4 includes a fixed side 401 that fits the diagonal side of the positioning groove 3 and a hanging side 402 on the other side. The fixed side 401 of the positioning grid 4 has the freedom to adjust the distance along the diagonal side of the positioning groove 3. Since the widths between the inner and outer walls of different construction sites are different, the thickness of the insulation board 1, the thickness of the steel grid 2, and the total distance between the two need to be adaptively adjusted. In order to enable the factory to unify the size when producing the insulation board 1, avoid opening multiple production lines of different sizes and models, and reduce production costs, the distance between the insulation board 1 and the steel grid 2 in the utility model can be fine-tuned to adapt to the width between different inner and outer walls. When adjusting the distance, the fixed side 401 of the positioning grid 4 can be dragged to move along the diagonal side of the positioning groove 3. When the horizontal distance reaches the required adjusted width, it can be tied and fixed. Moving along the diagonal side of the positioning groove 3 can prevent the steel grid 2 from shifting, ensuring that the steel grid 2 is always parallel to the insulation board 1.

[0029] The positioning groove 3 is provided with a distance nut 5, and the distance nut 5 is provided in multiple groups at equal intervals along the diagonal side of the positioning groove 3. The fixed side 401 of the positioning grid 4 is provided with a fixing nut 6. The positioning grid 4 is fixedly connected to the positioning groove 3 by means of bolts passing through the distance nut 5 and the fixing nut 6. In order to facilitate distance adjustment, a distance nut 5 is further provided along the diagonal side of the positioning groove 3. The horizontal intervals between adjacent distance nuts 5 are fixed. When the positioning grid 4 is fully inserted into the positioning groove 3, the fixing nut 6 on the positioning grid 4 is aligned with the innermost distance nut 5 of the positioning groove 3. When adjusting the distance between the insulation board 1 and the steel grid 2, move the steel grid 2 so that the fixing nut 6 is aligned with the distance nut 5 of the corresponding horizontal distance, and then fix it with bolts. If there is no distance nut 5 at the corresponding position on the positioning groove 3, it can be directly tied and fixed.

[0030] The positioning grid 4 is also provided with a connecting grid 7, the two ends of which are respectively tied and fixed to the hanging side 402 of the positioning grid 4 and the positioning slot 3, and the hanging side 402 and the positioning slot 3 are connected to form a whole by means of the connecting grid 7. Since the movement of the positioning grid 4 along the fixed side 401 will cause the hanging side 402 of the positioning grid 4 to gradually move away from the diagonal side of the positioning slot 3, affecting the integrity between the positioning grid 4 and the positioning slot 3, the connecting grid 7 is provided. The connecting grid 7 is L-shaped, with one end of the connecting grid 7 tied and connected to the hanging side 402 of the positioning grid 4, and the other end of the connecting grid 7 tied and connected to the diagonal side of the positioning slot 3, thereby improving the integrity between the positioning grid 4 and the positioning slot 3.

[0031] Specific embodiment 2, as shown in the figure, the only difference between specific embodiment 2 and specific embodiment 1 is that the angle of the positioning grid 4 in specific embodiment 1 is smaller, the V-shaped angle of the positioning grid 4 is smaller than the V-shaped angle of the positioning groove 3, and the gap between the positioning grid 4 and the positioning groove 3 is formed into a filling chamber 8. The positioning grid 4 is fixedly connected with the positioning groove 3 by means of cast-in-place concrete poured into the filling chamber 8. In specific embodiment 2, fixing nuts 6 are not used for bolted connection, and casting is used for integral molding. After the positioning grid 4 is matched with the positioning groove 3, they are first tied to form a pre-fixation, and then cast. During the casting process, the cast-in-place concrete will penetrate into the filling chamber 8, and the connection integrity between the positioning grid 4 and the positioning groove 3 will be improved after the cast-in-place concrete solidifies.
