Description

Technical Field

[0001] The invention relates to the technical field of building materials, and in particular to a high-strength lightweight composite wallboard and a wall system thereof suitable for rapid industrialized dry construction. Background Art

[0002] With the improvement of economic level and the acceleration of urbanization, the construction scale of the whole society is getting larger and larger, which also puts forward higher requirements on construction efficiency. New lightweight thermal insulation wall panel materials are gradually replacing traditional clay bricks, ceramsite concrete blocks and other materials, becoming the mainstream wall panel materials that are becoming more and more popular in the field of modern construction.

[0003] At present, the commonly used lightweight wallboard material is made by pouring lightweight concrete and polystyrene particles into polystyrene particle foam concrete board, and then covering the polystyrene particle foam concrete board with cement wood wool board on both sides. This kind of lightweight wallboard material has the advantages of heat preservation, heat insulation, sound insulation, light weight, and meeting Class A fire protection standards, so it is widely used.

[0004] However, the inventors of this application found that the above technology has at least the following technical problems in the process of implementing the technical solution of the invention in the embodiment of this application:

[0005] 1. The existing polystyrene particle foam concrete board is mainly made of lightweight (foam) concrete, which has the defects of being soft and brittle. The strength of the wallboard made of it is limited and it is not suitable for construction conditions with high strength requirements.

[0006] 2. The polystyrene particle foam concrete board and the cement wood wool board are connected through the self-adhesiveness of the cement wood wool board, but the viscosity of the cement wood wool board is not high. During use, the polystyrene particle foam concrete board and the cover of the cement wood wool board will be separated, affecting the use of the wall. The quality of the wall needs to be improved.

[0007] 3. The existing polystyrene particle foam concrete board can only be constructed by pouring lightweight concrete and polystyrene particles on site into the gaps between steel beams or steel columns of buildings, and then applying non-woven fabrics or mesh cloth to the cement wood wool board cover to make it smooth, so as to achieve the fixation of the polystyrene particle foam concrete board and the steel beams or steel columns of buildings. That is, the existing polystyrene particle foam concrete board can only be used for wet operations, which greatly increases the labor cost of on-site construction, requires a long construction time, and cannot meet the requirements of increasingly improved building integration and high-efficiency construction.

[0008] 4. The existing polystyrene particle foam concrete board can only be used once. After installation, it cannot be dismantled and reused. It is easy to generate a large amount of construction waste, causing waste of resources, which does not meet the requirements of green environmental protection and civilized construction advocated by modern society.

[0055] The embodiments of the present application provide a high-strength lightweight composite wall panel and its wall system, thereby solving the technical problems in the prior art that the polystyrene particle foam concrete panels are soft and fragile, of poor quality, can only be used in wet operations, have high labor costs, low construction efficiency, and can only be used once. The strength and quality of the wall panels are greatly improved, and the panels are suitable for rapid industrialized dry construction, which greatly reduces labor costs, meets the requirements of rapid, precise, and efficient construction, and can be dismantled and reused.

[0056] The technical solution in the embodiment of the present application is to solve the above-mentioned crosstalk problem, and the overall idea is as follows:

[0057] Based on the existing polystyrene particle foam concrete board, C-shaped steel plate heads are added on the left and right sides of the polystyrene particle foam concrete board when pouring, and then cement wood wool board covers are added on the front and back sides of the polystyrene particle foam concrete board. The polystyrene particle foam concrete board and the cement wood wool board cover are not only connected by the self-adhesiveness of the cement wood wool board, but also connected to the C-shaped steel plate heads on both sides of the wall panel by nailing, thereby reinforcing the strength of the entire wall panel.

[0058] Since C-shaped steel plate heads are installed on both sides of the wall panel, the strength of the entire wall panel is improved. At the same time, when the wall panel is connected to the steel beam or steel column of the building, the C-shaped steel plate heads on the side of the wall panel can be directly fixed to the steel beam or steel column with bolts. The connection is convenient and fast, and it truly achieves dry operation and rapid industrial construction. It breaks through the limitations of traditional polystyrene particle foam concrete panels that are soft and fragile and can only be used for wet operations.

[0059] Two adjacent wall panels are connected by C-shaped steel plate heads to form a large-area wall. Preferably, male and female tongue-and-groove C-shaped steel plate heads are designed at both ends of the wall panels, and the two adjacent wall panels are connected by the male and female tongue-and-groove C-shaped steel plate heads, and the male and female tongue-and-groove of the two mutually connected C-shaped steel plate heads are fixed with screws, so that not only the positioning connection of the wall panels can be achieved, but also the torsional strength of the wall system can be enhanced.

[0060] The wall panels of the above structure are suitable for interior wall panels. When used as exterior wall panels, concrete blocking blocks are prefabricated on the top of the wall panels of the above structure, and waterproof strips are installed between two adjacent wall panels to achieve the beneficial effects of heat preservation, heat insulation, sound insulation, waterproofing, light weight, and meeting Class A fire protection standards.

[0061] In addition, after installation and use, the wall panels provided in the embodiment of the present application can be dismantled and reused, without generating construction waste, thus saving resources and complying with the requirements of green environmental protection and civilized construction advocated by modern society.

[0062] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0063] Embodiment 1

[0064] Figure 1 to Figure 3 They are respectively a schematic diagram of the overall structure, an exploded view and a cross-sectional view of the high-strength lightweight composite interior wall panel provided in this embodiment. The high-strength lightweight composite interior wall panel is composed of a polystyrene particle foam concrete board 1, a C-shaped steel plate head 2, a cement wood wool board 3, nails 4 and other components.

[0065] The polystyrene particle foam concrete board 1 is cast by adding polystyrene particles to lightweight concrete. There are many boards of this material on the market, such as the "Koni Board" produced by Shanghai Kangni Building Materials Technology Co., Ltd. and the "Matsumoto Board" produced by Guangdong Songben Green Board Co., Ltd. The bulk density of the polystyrene particle foam concrete board 1 is less than 800kg / m 3 , it has the advantages of thermal insulation, heat insulation, sound insulation, light weight, and meeting Class A fire protection standards.

[0066] Combination Figure 4 The C-shaped steel plate end cap 2 includes a main cover side plate 21, one end of the main cover side plate 21 is vertically connected to one end of the first horizontal steel plate 22, the other end of the first horizontal steel plate 22 is bent inward to form a first auxiliary side plate 23, and the tail of the first auxiliary side plate 23 is bent inward to form a first hook 24; the other end of the main cover side plate 21 is vertically connected to one end of the second horizontal steel plate 25, the other end of the second horizontal steel plate 25 is bent inward to form a second auxiliary side plate 26, and the tail of the second auxiliary side plate 26 is bent inward to form a second hook 27. The C-shaped steel plate end cap 2 is a symmetrical structure.

[0067] The C-shaped steel plate end cap 2 is fixed on the left and right sides (thickness direction) of the polystyrene particle foam concrete board 1. The main cover side plate 21 of the C-shaped steel plate end cap 2 is arranged on the side of the polystyrene particle foam concrete board 1, the first horizontal steel plate 22 and the second horizontal steel plate 25 are respectively close to the front and rear surfaces of the polystyrene particle foam concrete board 1, and the first auxiliary side plate 23 and the first inverted hook 24, the second auxiliary side plate 26 and the second inverted hook 27 are all embedded in the polystyrene particle foam concrete board 1.

[0068] The front and rear sides (width direction) of the polystyrene particle foam concrete board 1 are fixed with cement wood wool boards 3 as covers. The cement wood wool boards 3 on the front and rear sides are respectively in close contact with the first horizontal steel plate 22 and the second horizontal steel plate 25 of the C-shaped steel plate end 2, and are fixed by nails 4. At the connection, the cement wood wool boards 3 on the front and rear sides are respectively located on the outside of the first horizontal steel plate 22 and the second horizontal steel plate 25.

[0069] During pouring, the polystyrene particle foam concrete, the C-shaped steel plate end cap 2, and the cement wood wool board 3 are all placed in the mold and cast in one piece. The cement wood wool board 3 is self-adhesive and is attached to the surface of the polystyrene particle foam concrete board 1. At the same time, the cement wood wool board 3 is connected and fixed to the C-shaped steel plate end cap 2 on both sides by nails 4, which further strengthens the strength of the entire wallboard and ensures that the cement wood wool board 3 will not fall off during the use of the wallboard.

[0070] The high-strength lightweight composite inner wall panel provided in this embodiment can be prefabricated into multiple modules and then transported to the construction site for assembly. During assembly, the main cover side panels 21 of the C-shaped steel plate heads 2 of two adjacent inner wall panels are aligned and tightly attached, and fixed by screws 5 to form a large-area inner wall body. Figure 5 shown.

[0071] When the high-strength lightweight composite inner wall panel provided in this embodiment is connected to the building steel column 7 at the construction site, the main cover side plate 21 of the C-shaped steel plate head 2 on the side of the inner wall panel can be directly fixed to the H-shaped steel column 7 with bolts 6. Figure 6 The connection between the inner wall panels and the steel columns is convenient and fast, which truly achieves dry operation and rapid industrialized construction, breaking through the limitations of traditional polystyrene particle foam concrete panels that are soft and fragile and can only be used for wet operations.

[0072] The thickness of the high-strength lightweight composite interior wall panel provided in this embodiment is generally about 10 cm, and can be appropriately adjusted according to specific use conditions.

[0073] The wall system composed of the high-strength lightweight composite interior wall panels provided in this embodiment has obvious advantages over the traditional lightweight wall system:

[0074] 1. Material cost is significantly reduced. The traditional lightweight wall system is composed of G550 light steel, rock wool and auxiliary materials. The material cost of the wall system of this embodiment is significantly reduced compared with the traditional lightweight wall system.

[0075] 2. The installation cost is significantly reduced. The traditional lightweight wall system is made of multiple materials stacked together, which is complicated to operate, takes a long time to install, and has high installation costs. The wall system of this embodiment is directly assembled from high-strength lightweight composite wall panels, which has high integration, simple and fast operation, and low installation costs. The installation cost of the wall system of this embodiment is less than one-third of that of the traditional lightweight wall system.

[0076] 3. The installation efficiency is significantly improved. Based on the area (259.2m2) of a container (11.88m*2.32m*2.55m) filled with high-strength lightweight composite interior wall panels (120mm thick) 2 ) is taken as the base number, taking an inner wall of 259.2 square meters as an example, a traditional lightweight wall system requires 12 workers in 20 days to complete, while the wall system of this embodiment only requires 6 workers in 10 days to complete.

[0077] It is worth noting that, according to different usage conditions, the polystyrene particle foam concrete board 1 in this embodiment can also be replaced by other lightweight wall core boards, and the cement wood wool board 3 in this embodiment can also be replaced by other covers.

[0078] The technical solutions in the above embodiments of the present application have at least the following technical effects or advantages:

[0079] 1. By installing C-shaped steel plate heads on both sides of the inner wall panels, the problem of the existing polystyrene particle foam concrete panels being soft and fragile is solved. The strength of the manufactured inner wall panels is greatly improved, and they are suitable for construction conditions with high strength requirements.

[0080] 2. By installing C-shaped steel plate heads on both sides of the inner wall panels, when the inner wall panels are connected to the steel beams or steel columns of the building, the C-shaped steel plate heads on the sides of the inner wall panels can be directly fixed to the steel beams or steel columns with bolts. The connection is convenient and fast, truly achieving dry operation and rapid industrialized construction.

[0081] 3. By installing C-shaped steel plate heads on both sides of the inner wall panels, when assembling two adjacent inner wall panels, align the C-shaped steel plate heads of the two adjacent inner wall panels tightly and fix them with screws to splice them into a large-area inner wall.

[0082] 4. The polystyrene particle foam concrete board and the two cement wood wool board covers are not only connected by the self-adhesiveness of the cement wood wool board, but also connected to the C-shaped steel plate heads on both sides of the inner wall board by nailing. This strengthens the connection strength of the entire inner wall board. The cement wood wool board will not fall off during use, ensuring the quality of the inner wall.

[0083] 5. The high-strength and lightweight composite interior wall panels provided in the embodiments of the present application can be pre-fabricated in modular form and can be assembled and connected at the construction site. They are suitable for rapid industrialized dry construction, greatly reducing labor costs, meeting the requirements of rapid, precise and efficient construction, and promoting the process of building industrialization. They have broad application prospects.

[0084] 6. The high-strength lightweight composite interior wall panels provided in the embodiments of the present application can be dismantled and reused after installation and use, without generating construction waste, thus saving resources and complying with the requirements of green environmental protection and civilized construction advocated by modern society.

[0085] Embodiment 2

[0086] Figure 7 to Figure 9 They are respectively the overall structural schematic diagram, exploded diagram and cross-sectional diagram of the high-strength lightweight composite inner wall panel provided in this embodiment, and the high-strength lightweight composite inner wall panel is substantially the same as the embodiment, and the only difference is that the main cover side panels 21 of the C-shaped steel plate end cap 2 on the left and right sides in the first embodiment are respectively designed to have male and female tongues and grooves. In this embodiment, the male and female tongues and grooves are formed by bending the main cover side panels into a step shape.

[0087] like Fig.10 As shown, the C-shaped steel plate head 2 includes a first stepped side panel 211, one end of the first stepped side panel 211 is connected to one end of a stepped horizontal steel plate 212, and the other end of the stepped horizontal steel plate 212 is connected to one end of a second stepped side panel 213; the other end of the first stepped side panel 211 is vertically connected to one end of the first horizontal steel plate 22, and the other end of the first horizontal steel plate 22 is bent inward to form a first auxiliary side panel 23, and the tail of the first auxiliary side panel 23 is bent inward to form a first inverted hook 24; the other end of the second stepped side panel 213 is vertically connected to one end of the second horizontal steel plate 25, and the other end of the second horizontal steel plate 25 is bent inward to form a second auxiliary side panel 26, and the tail of the second auxiliary side panel 26 is bent inward to form a second inverted hook 27.

[0088] The structures of the C-shaped steel plate heads 2 on the left and right sides of the polystyrene particle foam concrete board are set correspondingly, and the C-shaped steel plate head 2 on the right side is formed by horizontally flipping the C-shaped steel plate head 2 on the left side and then vertically flipping it. That is, the C-shaped steel plate head 2 on one side is concave at the top and convex at the bottom, and the C-shaped steel plate head 2 on the other side is convex at the top and concave at the bottom.

[0089] When the inner wall is spliced, two adjacent inner wall panels are connected by a C-shaped steel plate head with male and female tongues and grooves, and the male and female tongues and grooves of the two C-shaped steel plate heads connected to each other (in this embodiment, the stepped horizontal steel plates 212) are fixed by screws 5, such as Fig.11 As shown, in this way, not only the positioning connection of the inner wall panels can be achieved, but also the torsional strength of the inner wall can be enhanced.

[0090] When the high-strength lightweight composite inner wall panel provided in this embodiment is connected to the building steel column 7 at the construction site, the C-shaped steel plate head 2 on the side of the inner wall panel can be directly fixed to the steel column 7 with bolts 6. The C-shaped steel plate head connected to the H-shaped steel column 7 at the end does not need to be provided with male and female tongues and grooves. The surface where the C-shaped steel plate head is connected to the steel column 5 can be set as a common plane as in the first embodiment. Fig.12 shown.

In this way, not only the positioning connection of the inner wall panels can be achieved, but also the torsional strength of the inner wall system can be enhanced.

The high-strength lightweight composite interior wall panel is composed of a polystyrene particle foam concrete board 1, a C-shaped steel plate head 2, a cement wood wool board 3, nails 4, a concrete sealing block 8, a waterproof strip 9 and other components.

[0095] The polystyrene particle foam concrete board 1 is cast by adding polystyrene particles to lightweight concrete. There are many boards of this material on the market, such as the "Koni Board" produced by Shanghai Kangni Building Materials Technology Co., Ltd. and the "Matsumoto Board" produced by Guangdong Songben Green Board Co., Ltd. The bulk density of the polystyrene particle foam concrete board 1 is less than 800kg / m 3 , it has the advantages of thermal insulation, heat insulation, sound insulation, light weight, and meeting Class A fire protection standards.

At the connection between the cement wood wool board 3 and the C-shaped steel plate end cap 2, the cement wood wool board 3 is located outside the C-shaped steel plate end cap 2 and is fixed by nails 4.

[0097] like Fig.16As shown, the C-shaped steel plate head 2 includes a side steel plate 20, one end of the side steel plate 20 is vertically connected to one end of the first horizontal steel plate 22, the other end of the first horizontal steel plate 22 is bent inward to form a first auxiliary side plate 23, and the tail of the first auxiliary side plate 23 is bent inward to form a first inverted hook 24; the other end of the side steel plate 20 is vertically connected to one end of the second horizontal steel plate 25, the other end of the second horizontal steel plate 25 is bent inward to form a second auxiliary side plate 26, and the tail of the second auxiliary side plate 26 is bent inward to form a second inverted hook 27.

[0098] Male and female tongues and grooves are respectively arranged on the side steel plates 20 of the C-shaped steel plate heads 2 on both sides. In this embodiment, the male and female tongues and grooves are matched concave and convex structures. A water barrier strip installation groove 28 is arranged in the center of the side steel plate 20 for fixing the water barrier strip 9. The water barrier strip 9 is a rubber strip for realizing a sealed and waterproof connection between the C-shaped steel plate heads 2 of two adjacent exterior wall panels.

[0099] The concrete blocking block 8 is fixed on the top of the polystyrene particle foam concrete board 1 , and covers the top of the C-shaped steel plate head 2 and the top of the cement wood wool board 3 , and presses the water barrier strip 9 .

[0100] During pouring, the polystyrene particle foam concrete, C-shaped steel plate head, water barrier, cement wood wool board, and concrete blocking block are all placed in the mold and cast in one piece. During the coagulation process of the polystyrene particle foam concrete, the concrete blocking block and the polystyrene particle foam concrete board body are condensed together to form a high-strength exterior wall panel.

[0101] In this embodiment, the concrete blocking block 8 is prefabricated. The concrete blocking block 8 has the following two functions: First, the concrete used in the concrete blocking block 8 is higher than the grade of the polystyrene particle foam concrete board 1. The water barrier 9 is pressed by the exquisite concrete blocking block 8, and the sealing of the entire wall panel is guaranteed. Second, when pouring the polystyrene particle foam concrete, the bottom mold is first fixed with the surrounding components in the process, and then poured from the top opening. There will be bubbles and a certain amount of swelling during the process. Inserting the exquisite prefabricated concrete blocking block 8 into the head can solve the bubbles and the roughness of the end edge during swelling. Because the bottom of the wall panel is limited by the mold, the edge is naturally smooth due to the action of gravity, so there is no need to set up a concrete blocking block.

[0102] The cement wood wool board 3 itself is self-adhesive and is adhered to the surface of the polystyrene particle foam concrete board 1. At the same time, the cement wood wool board 3 is connected and fixed to the C-shaped steel plate heads 2 on both sides by nails 4, which further strengthens the strength of the entire exterior wall panel and ensures that the cement wood wool board 3 will not fall off during the use of the exterior wall panel.

[0103] The high-strength lightweight composite exterior wall panels provided in this embodiment can be prefabricated into multiple modules and then transported to the construction site for assembly. During assembly, the male and female tongues and grooves of the side steel plates 20 of the C-shaped steel plate heads 2 of the two adjacent exterior wall panels are matched tightly, and a water barrier strip 9 is installed in the water barrier strip installation groove 28 between the C-shaped steel plate heads of the two adjacent exterior wall panels, and then the side steel plates 20 of the C-shaped steel plate heads of the two adjacent exterior wall panels are fixed by screws 5 to form a large-area exterior wall body, such as Fig.17 shown.

[0104] When the high-strength lightweight composite interior wall panel provided in this embodiment is connected to the building steel column 7 at the construction site, bolts 6 are sequentially passed through the steel column 7, the cement wood wool board 3, and the first horizontal steel plate 22 or the second horizontal steel plate 25 of the C-shaped steel plate end 2 and fixed. Fig.17 The connection between the exterior wall panels and the steel columns is convenient and fast, which truly achieves dry operation and rapid industrialized construction, breaking through the limitation that the traditional polystyrene particle foam concrete panels are soft and fragile and can only be used for wet operations.

[0105] For places where windows are set, the side steel plate 20 of the C-shaped steel plate head 2 on that side of the exterior wall panel does not have male and female tongue and groove, and can be directly set as a flat surface, such as Fig.18 shown.

[0106] The thickness of the high-strength lightweight composite exterior wall panel provided in this embodiment is generally about 15.2 cm, and can be appropriately adjusted according to specific use conditions.

[0107] It is worth noting that, according to different usage conditions, the polystyrene particle foam concrete board 1 in this embodiment can also be replaced by other lightweight wall core boards, and the cement wood wool board 3 in this embodiment can also be replaced by other covers.

[0108] The technical solutions in the above embodiments of the present application have at least the following technical effects or advantages:

[0109] 1. By adding C-shaped steel plate heads on both sides of the exterior wall panels, the problem of the existing polystyrene particle foam concrete panels being soft and fragile is solved. The strength of the manufactured exterior wall panels is greatly improved, and they are suitable for construction conditions with high strength requirements.

[0110] 2. By installing C-shaped steel plate heads on both sides of the exterior wall panels, when the exterior wall panels are connected to the steel beams or steel columns of the building, the C-shaped steel plate heads on the sides of the exterior wall panels can be directly fixed to the steel beams or steel columns with bolts. The connection is convenient and fast, truly achieving dry operation and rapid industrialized construction.

[0111] 3. The two adjacent exterior wall panels are connected by C-shaped steel plate heads with male and female tongues, and the male and female tongues of the two C-shaped steel plate heads connected to each other are fixed with screws. In this way, not only the positioning connection of the exterior wall panels can be achieved, but also the torsional strength of the exterior wall can be enhanced.

[0112] 4. Install a waterproof strip on the outside of the C-shaped steel plate head. When assembling two adjacent exterior wall panels, seal and fix the C-shaped steel plate head with bolts, and sandwich a waterproof strip in the middle to splice into a large area of ​​exterior wall with waterproof function, thereby improving the waterproof performance of the wall.

[0113] 5. A prefabricated concrete sealing block is provided on the top of the exterior wall panel. The water barrier is pressed by the exquisite concrete sealing block, and the sealing of the entire wall panel is guaranteed. At the same time, when pouring the polystyrene particle foam concrete, the bottom mold is first fixed with the surrounding components, and then poured from the top opening. There are bubbles and a certain amount of swelling in the process. Inserting the exquisite prefabricated concrete sealing block into the head can solve the bubbles and the roughness of the end edge during expansion, and obtain a flat, exquisite and beautiful exterior wall panel.

[0114] 6. The polystyrene particle foam concrete board and the two cement wood wool board covers are not only connected by the self-adhesiveness of the cement wood wool board, but also connected to the C-shaped steel plate heads on both sides of the exterior wall board by nailing. This strengthens the connection strength of the entire exterior wall board. The cement wood wool board will not fall off during use, ensuring the quality of the exterior wall.

[0115] 7. The high-strength lightweight composite exterior wall panels provided in the embodiments of the present application can be pre-fabricated in modular form and can be assembled and connected at the construction site. They are suitable for rapid industrialized dry construction, greatly reducing labor costs, meeting the requirements of rapid, precise and efficient construction, and promoting the process of building industrialization. They have broad application prospects.

[0116] 8. The high-strength lightweight composite exterior wall panels provided in the embodiments of the present application can be dismantled and reused after installation and use, without generating construction waste, thus saving resources and complying with the requirements of green environmental protection and civilized construction advocated by modern society.
