Description

Technical Field

[0001] The utility model relates to the field of general building construction and also to the field of cable or wire installation, in particular to a prefabricated lightweight partition board and an inner partition wall structure comprising the partition board. Background Art

[0002] As a kind of partition board prefabricated in the factory and installed on site, gypsum lightweight partition board has the advantages of light weight, high strength, small shrinkage, good sound insulation, anti-insect, good decorative effect, economy, convenient construction, etc., and is widely used in the construction field. After the partition board is installed, it is often necessary to install the corresponding electrical secondary piping, wire boxes, and boxes on the partition board to facilitate the installation of the corresponding electrical circuits and equipment components in the later stage. Due to the particularity of the structure of gypsum lightweight partition board and the limitations of mechanized production, electrical piping, wire boxes, and boxes can only be laid out on the wall after installation, cut and grooved, and pipes and boxes are laid in the grooves. After installation, mortar is applied in layers to conceal them. Gypsum lightweight partition board has a hole-type hollow structure. Grooving often causes damage and cracking of thin-walled parts, destroys the wall structure, causes damage to the finished product, and consumes a lot of finished product materials. After cutting and grooving, necessary pipe burial, plastering and maintenance are required. The mortar materials and labor costs for repair are high. The repaired positions are prone to quality defects such as low strength, hollowing, and cracking, which is extremely unfavorable to the construction schedule organization, energy conservation and environmental protection.

[0003] Pipes are pre-buried in partition boards during production. The pipes form channels inside the partition boards. The channels are used for pipeline installation, thus avoiding the construction method of large-scale cutting and grooving of partition boards. However, after the partition boards are fixedly installed, the position of the channels is fixed, and the channels often do not align with the positions of existing pipelines, making it inconvenient to run electrical lines through the channels.

[0022] The utility model will be further described below in conjunction with the accompanying drawings.

[0023] The first subject of the utility model is a prefabricated lightweight partition board. Figure 1 and Figure 2 The prefabricated lightweight partition board includes a board body 1 with a rectangular outer contour. The six faces of the board body 1 are two oppositely arranged board surfaces, two side surfaces and two end surfaces. The two board surfaces are parallel to each other and are the two faces with the largest area of ​​the board body 1. The two end surfaces are parallel to each other and are the two faces with the smallest area of ​​the board body 1. When the board body 1 forms a wall, the two end surfaces are one above and one below and are horizontal. The two board surfaces and the two side surfaces are vertical. The two side surfaces are used for splicing, and the two board surfaces are used to form wall surfaces respectively. The two side surfaces of the board body 1 are spliced ​​with each other by users, or with structures such as structural columns and columns. The two side surfaces of the board body 1 are generally flat. In order to facilitate the prefabricated lightweight partition boards to be spliced ​​more firmly through the side surfaces, mutually adaptable bite joints are arranged between the two side surfaces of the board body 1. The bite joint enables the two spliced ​​board bodies 1 to at least resist the load perpendicular to the board surface. For example, see Figure 2A convex ridge is arranged on one side of the plate body 1, and a groove matching the convex ridge is arranged on the other plate surface, that is, a male tenon is arranged on one side of the plate body 1, and a female tenon matching the convex ridge is arranged on the other plate surface.

[0024] A connecting groove 11 is provided between at least one of the two plate surfaces of the plate body 1 and the two end surfaces, respectively. The connecting groove 11 is a gap reserved between one plate surface and one end surface of the plate body 1. The outline of the connecting groove 11 is generally a rectangular parallelepiped shape. In order to avoid the connecting groove 11 being too large, which will reduce the strength of the plate body 1 too much and affect the lifting, transportation and installation of the plate body 1, the width of the connecting groove 11 should not be too large. Generally, the width of the connecting groove 11 is not greater than half of the width of the plate body 1, wherein the width of the plate body 1 is the distance between the two side surfaces, and the width of the connecting groove 11 is the distance between the two inner walls parallel to the side surfaces of the plate body 1.

[0025] The board surface provided with the connection slot 11 is also provided with a wire box 12, which is buried in the board body 1, that is, the wire box 12 is embedded in the board body 1, and the wire box 12 is used for the later installation of terminals such as switches and controllers. At least two connecting pipes 13 are respectively provided between the two connection slots 11 and the wire box 12 on the same board surface. The connecting pipe 13 is determined according to the number of pipelines, for example, Figure 1 and Figure 2 In the illustrated embodiment, two connecting pipes 13 are respectively arranged between two connecting grooves 11 and the wire box 12 on the same board surface. Each connecting pipe 13 is buried in the board body 1, and the two ends of the connecting pipe 13 are respectively located in the wire box 12 and the connecting groove 11, and the connecting pipe 13 directly connects the connecting groove 11 with the wire box 12. The connecting pipe 13 can be made of plastic or metal pipe. In order to make the connecting pipe 13 play a role in improving the strength of the board body 1, the connecting pipe 13 is preferably a metal pipe. In order to avoid the problem of rust, the connecting pipe 13 is made of rust-resistant material, or an anti-rust layer is provided. In order to facilitate the insertion of cables in the connecting pipe 13, the connecting pipe 13 is preferably a straight round pipe. In order to shorten the length of the connecting pipe 13, the wire box 12 on the same board surface of the board body 1 and the center of the two connecting grooves 11 are located in the same straight line, and the straight line is perpendicular to the two end faces of the board body 1, that is, the connecting pipe 13 is arranged vertically when the prefabricated lightweight partition board is used.

[0026] The board body 1 of the prefabricated lightweight partition board is produced in the factory by lightweight materials or foaming and is directly installed on site. Prefabricated lightweight partition boards are lightweight building materials and can be hollow structures or solid structures. For example, the board body 1 is a gypsum board, or the board body 1 is made of LC20 lightweight aggregate concrete. In order to avoid deformation and displacement of the connecting pipe 13 and the wire box 12, one end of the connecting pipe 13 is fixedly connected to the wire box 12. For example, the wire box 12 is fixedly provided with a lock nut, and one end of the connecting pipe 13 is connected to the lock nut. By fixing the connecting pipe 13 and the wire box 12 as a whole, it is convenient to fix the whole, and avoid deformation and displacement of the connecting pipe 13 and the wire box 12 caused by the vibration of the casting board body 1.

[0027] The second subject of the utility model is the internal partition wall structure. Figure 3 and Figure 4 The internal partition wall structure is composed of a wall body formed by splicing at least two prefabricated wall panels in sequence, an upper horizontal structure 2 located at the top of the wall body, a lower horizontal structure 3 located at the bottom of the wall body, and a vertical main structure 4 located at the side of the wall body. The upper horizontal structure 2 and the lower horizontal structure 3 are generally ring beams, cross beams or other reinforced concrete structures, and the vertical main structure 4 is generally a structural column, a column or other reinforced concrete structure.

[0028] The wall is fixedly connected to the upper horizontal structure 2 and the lower horizontal structure 3, and the wall is fixedly connected to the vertical main structure 4. For the convenience of construction, the vertical main structure 4 and the upper horizontal structure 2 are respectively fixedly installed with U-shaped connecting steel clips 6, the opening of the U-shaped connecting steel clips 6 faces one side of the wall, and the wall is stuck in the U-shaped connecting steel clips 6. The U-shaped connecting steel clips 6 can be fixed by concrete nails. In order to more firmly fix each prefabricated wall panel, U-shaped connecting steel clips 6 are set at the joints of two adjacent prefabricated wall panels, such as Figure 3 shown.

[0029] At least one of the prefabricated wall panels spliced ​​to form the wall is the prefabricated lightweight partition board described in the first subject, and the two end faces of the prefabricated lightweight partition board are fixedly connected to the lower horizontal structure 3 and the upper horizontal structure 2 respectively. The prefabricated wall panels can also be made of gypsum lightweight partition boards, that is, at least one prefabricated wall panel is a gypsum lightweight partition board. In order to facilitate the adjustment of the position of the prefabricated wall panels during installation, including the adjustment of the height and horizontal position, a wedge-shaped support block 7 is arranged between the prefabricated wall panel and the lower horizontal structure 3. The support block 7 is one or more, and the support block 7 plays a role of temporary support. For example, the support block 7 is a wooden wedge. The gap between the prefabricated wall panel and the lower horizontal structure 3 is filled with mortar, and the mortar plays a dual role of fixing and bonding. There is an installation gap between the prefabricated wall panel and the upper horizontal structure 2, and the gap is filled with mortar, which also plays a dual role of fixing and bonding.

[0030] The connecting grooves 11 at the upper and lower ends of the plate body 1 are directly connected to the upper horizontal structure 2 and the lower horizontal structure 3 respectively. In order to facilitate the connection of the existing pipelines located in the lower horizontal structure 3 or the upper horizontal structure 2 with the end of the connecting pipe 13 located in the connecting groove 11, the end of the connecting pipe 13 located in the connecting groove 11 is connected to the extension pipe 5, and the other end of the extension pipe 5 is used to connect the existing pipeline. The extension pipe 5 can be made of PVC pipe, and the extension pipe 5 can be moderately bent by its own flexibility to adapt to the installation position deviation. After the pipeline is connected, the connecting groove 11 is leveled with mortar to be parallel to the board surface, that is, the mortar is filled in the connecting groove 11, and the extension pipe 5 is buried in the mortar. For example, 1:3 cement mortar is used to fill the connecting groove 11 in layers.

[0031] During construction, a hydraulic forklift is used to transport the prefabricated wall panels to the floor, the positioning line is placed, and the U-shaped connecting steel clip 6 is fixed with concrete nails. The top of the prefabricated wall panel is coated with 1:2.5 cement mortar or special adhesive mortar with a coating thickness of 20mm, and the bottom is leveled and bonded with 1:2.5 dry-mixed mortar, and a wedge-shaped support block 7 is inserted for temporary fixation. The prefabricated wall panels are connected by bite results and filled with gypsum mortar or cement mortar. 14 days after the prefabricated wall panels are installed, the surface anti-cracking decorative plastering can be carried out. The surface of the wall is fully coated with interface agent, and alkali-resistant glass fiber cloth is used for different materials and joints, and anti-cracking mortar is applied for layered leveling, and then alkali-resistant fiber cloth is fully hung and modified gypsum mortar is used for plastering and compaction.
