[0002] Internal partition boards refer to prefabricated wall panels used for internal partitions of buildings, including cement panels, gypsum hollow panels, light concrete panels, composite sandwich light panels, etc. In order to ensure sound insulation performance, existing partition boards are often provided with sound insulation panels inside the partition boards. For example, the patent document with authorization announcement number CN 212957122U discloses a sound insulation and heat preservation type light partition board, including a light partition board body, which is composed of an outer partition board, a sound insulation board and an inner partition board, the inner side of the outer partition board is fixedly connected to the outer side of the sound insulation board, and the inner side of the sound insulation board is fixedly connected to the outer side of the inner partition board.

[0003] Although this type of internal partition board has played a certain role in sound insulation, it still has the following disadvantages: First, the sound insulation board, the outer partition board and the inner partition board are only connected layer by layer, which is prone to problems such as low layer bonding strength and easy falling off. Therefore, there is room for improvement in overall stability and structural strength. Second, the internal partition board adopts a single-layer sound insulation board, and the sound insulation performance is average, and the sound insulation effect needs to be further improved. Third, the internal partition boards adopt a structure in which the clamping column is inserted into the clamping groove for interlocking, and the clamping column and the clamping groove are provided with pluggable barbs. Although the interlocking stability is guaranteed, its processing technology is complicated and the mold production requirements are quite high, resulting in an increase in the overall production cost.

[0035] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0036] like Figure 1-9 As shown, this embodiment proposes an assembled fiber-reinforced modified composite strip board interior partition wall, which is composed of several interior partition wall strip boards 1 spliced ​​together. The structural form can be seen in the attached Fig. 9 In this embodiment, the inner partition wall strip 1 uses industrial byproduct gypsum, cement, fly ash as the main raw materials, mixed with reinforcing fiber, modifier and other materials, and has a built-in fireproof and soundproof material 11 in the middle. It is a high-strength and water-resistant composite strip with semicircular grooves on both sides of the vertical casting in the factory. The structural form of the above-mentioned inner partition wall strip 1 mainly includes the following:

[0037] The inner partition wall strip 1 includes a sound insulation layer, which has a good sound insulation effect; the sound insulation layer includes two layers of fireproof and soundproof materials 11 arranged at intervals, and the two layers of fireproof and soundproof materials 11 are connected and fixed by a limiting fixing member 4 to form an integral sound insulation layer; a surface layer 12 is coated around the fireproof and soundproof materials 11, and the surface layer 12 is cast with strip slurry, and the strip slurry is a modified inorganic material, and a strip-like structure is formed after casting; the fireproof and soundproof materials 11 and the limiting fixing member 4 are completely built in the surface layer 12, and the whole constitutes the inner partition wall strip 1.

[0038] As a preferred embodiment, in order to prevent falling off and ensure stability after connection, the fireproof and soundproofing material 11 is provided with a number of through holes 111 for forming connecting columns. The through holes 111 are arranged along the length direction of the inner partition wall strips 1, and the through holes 111 include but are not limited to round holes, square holes or holes in other structural forms; in this embodiment, two groups of through hole 111 arrays are arranged on each inner partition wall strip 1, and each group of through hole 111 arrays includes 5 through holes 111, forming a structure similar to the "five-cake" style. In this way, after pouring the strip slurry, the mortar can flow into the through holes 111, and after hardening, a connecting column can be formed, which can ensure a reliable connection between the surface layer 12 and the sound insulation layer, and is not easy to fall off.

[0039] As mentioned above, the fireproof and soundproof materials 11 are connected and positioned by the limiting fixing members 4, and the specific connection relationship is as follows:

[0040] A through positioning hole 112 is also provided on the fireproof and soundproofing material 11; the positioning hole 112 is used for assembly with the limiting fixing piece 4; wherein, the limiting fixing piece 4 includes a tension bolt rod 41, and the tension bolt rod 41 can pass through the positioning hole 112; both ends of the tension bolt rod 41 respectively have threaded sections; a chuck 44 for limiting the fireproof and soundproofing material 11 is also detachably connected to the tension bolt rod 41 between the two threaded sections; a nut 42 is threadedly connected to the threaded section, and the nut 42 has a screw hole 431 adapted to be connected to the threaded section, and a pressure plate 43 is fixedly connected to the nut 42, and the pressure plate 43 and the chuck 44 are respectively positioned on both sides of the fireproof and soundproofing material 11.

[0041] When in use, the tension bolt rod 41 is passed through the positioning hole 112, and then the chuck 44 is inserted and connected to the tension bolt rod 41, and the chuck 44 is positioned on one side of the fireproof and soundproof material 11; then the nut 42 is screwed, and the nut 42 is pressed and positioned on the other side of the fireproof and soundproof material 11, and the nut 42 cooperates with the chuck 44 to clamp and fix the fireproof and soundproof material 11; the spacing between the two layers of fireproof and soundproof material 11 is determined by the distance between the two chucks 44.

[0042] Regarding the detachable connection between the chuck 44 and the tension bolt rod 41, the following structural forms can be adopted:

[0043] The tension bolt rod 41 is provided with a slot 411, and a part of both sides of a suitable position of the tension bolt rod 41 is turned away to form the slot 411; the chuck 44 is provided with a slot 442, and the slot 442 extends from the edge of the chuck 44 to the middle position, and the slot 442 can be adapted and plugged with the slot 411. When in use, the chuck 44 is inserted along the slot 411, and the outer wall of the tension bolt rod 41 is supported at the top position of the slot 442. Due to the limitation of the slot 411, the chuck 44 cannot be displaced left and right, and can well realize the support of the fire-proof and sound-proof material 11.

[0044] As a more optimal solution, a spike 443 is also provided on the side of the chuck 44. The main function of the spike 443 is to achieve an effective connection between the chuck 44 and the fireproof and soundproof material 11 to prevent the chuck 44 from falling off. After installation, the spike 443 of the chuck 44 can be inserted into the fireproof and soundproof material 11 for fixation. In this way, the chuck 44 and the tension bolt rod 41 and the fireproof and soundproof material 11 can be better fixedly connected.

[0045] Through the above reasonable structural design, the sound insulation layer and the surface layer 12 in this embodiment can be firmly combined. Since the sound insulation layer adopts a double-layer fireproof sound insulation material 11, the double-layer fireproof sound insulation material 11 is positioned and fixed by the limiting fixing member 4, which not only enhances the sound insulation effect and improves the sound insulation performance, but also can achieve a stable connection between the fireproof sound insulation material 11 and the surface layer 12, which can improve the overall structural strength and solve the technical problems of easy falling off and low bonding strength caused by the simple connection between the layers in the prior art.

[0046] In addition, the fireproof and soundproofing materials 11 are positioned and fixedly connected by the limiting fixing parts 4, which can effectively ensure the spacing between the fireproof and soundproofing materials 11. When pouring the strip slurry, the fireproof and soundproofing materials 11 are not easily displaced to prevent deformation; the limiting fixing parts 4 adopt the method of tension bolt rods 41 and detachable chucks 44, which are simple to process, convenient to construct, and easy for workers to operate.

[0047] It should be noted that, in this embodiment, the fireproof and sound-insulating material 11 is a reinforced sound-insulating material, ceramsite or foamed cement board.

[0048] In this embodiment, in order to facilitate installation and realize interlocking, the following structural design is also made:

[0049] Semicircular grooves 2 are provided at both vertical ends of the inner partition wall strips 1; after installation, a butt-jointed circular groove is formed between adjacent inner partition wall strips 1, which can be referred to in the attached Fig. 9 .

[0050] At the joints of adjacent inner partition wall strips 1, the surface of the inner partition wall strips 1 is provided with an inward-retracted recessed cavity 3. When the recessed cavity 3 is used for joint processing, a flexible adhesive mortar composite caulking tape is used to bond the recessed cavity to smooth the joint. With this structure, while improving overall stability, reliability and crack resistance and effectively ensuring construction quality, it is easy to process and manufacture, which can reduce production costs, optimize production processes, and reduce costs and increase efficiency.

[0051] It should be noted that the inner partition wall strips 1 are butted against each other using semicircular grooves 2, and the following anti-cracking measures are taken according to the partition walls of different structures and different parts:

[0052] 1. Gypsum grouting slurry should be poured into the circular grooves between the strips, and the joints should be treated with flexible adhesive mortar composite caulking tape for crack resistance; this operation achieves the interlocking of the inner partition wall strips 1, improves the overall stability, reliability and crack resistance, and effectively ensures the construction quality;

[0053] 2. Anti-crack treatment should be done at the corners of the partition wall and at the junction of the strip board and the main structure of the building;

[0054] 3. Leave a gap of not less than 10mm between the inner partition board 1 and the main structure, the top, and the door and window openings. Fill it with flexible connecting materials (EPS boards or PE materials) and fill it with modified glue powder polystyrene particle slurry. Use flexible adhesive slurry composite glass fiber mesh or seam paper tape for anti-cracking treatment.

[0055] It should be noted that, in order to improve the strength of the main structure, reinforcement layers are provided on both sides of the sound insulation layer, and the reinforcement layers are built into the surface layer 12. In this embodiment, the reinforcement layer is a steel wire mesh or a glass fiber mesh or a carbon fiber mesh.

[0059] 3. The positioning plate should be installed first. The reserved installation gap between the lower end of the inner partition wall strip 1 and the ground should not be greater than 40mm, and can be adjusted as needed;

[0060] 4. Drive a wooden wedge into the lower part of the inner partition board 1 and tighten it. The position of the wooden wedge should be in the middle of the board.

[0061] 5. Use wooden wedges to adjust the position. Two wooden wedges form a group to put the inner partition wall strip 1 in place. The inner partition wall strip 1 can be adjusted vertically upward to press against the bottom of the beam or floor slab. After adjusting the verticality of the board, tighten the wooden wedges to fix it.

[0062] 6. The inner partition wall strips 1 should be installed in sequence, and the semicircular grooves 2 on the vertical end faces between the boards should be aligned and tightly spliced. The vertical and adjacent board surface flatness should be adjusted;
