Description

Technical Field

[0001] The utility model relates to the technical field of recycled concrete composite hollow floor slab structures, in particular to a thermal insulation and sound insulation recycled concrete composite hollow floor slab structure. Background Art

[0002] Insulated and soundproof recycled concrete composite hollow-core slabs are a new building material that combines insulation, sound insulation, and structural functions. These slabs are typically made of multiple layers of recycled concrete, insulation, and sound insulation, produced through a laminated process.

[0003] After searching, the Chinese patent "Thermal insulation and sound insulation recycled concrete composite hollow floor structure" authorization announcement number "CN219033725U" realizes a lightweight and stable hollow floor structure through a fine stone concrete leveling layer, a waterproof layer of polyurethane waterproof coating, cast-in-place recycled concrete slabs, prefabricated hollow concrete slabs, hollow holes, cement mortar plaster layer and truss steel bars. While ensuring the mechanical properties, it improves the thermal insulation and sound insulation performance of the wall and reduces the weight.

[0004] In the above application, the inner wall of the hollow hole is concave in an octagonal shape, which easily leads to uneven filling of the sound insulation material in the hollow hole and the existence of a gap between the two hollow holes, thereby reducing the thermal insulation and sound insulation effect of the hollow floor structure.

[0005] Therefore, a thermal insulation and sound insulation recycled concrete composite hollow floor structure is proposed to solve the above problems. Utility Model Content

[0006] The purpose of the present utility model is to provide a thermal insulation and sound insulation recycled concrete composite hollow floor structure in order to solve the above problems, thereby improving the problem that the inner wall of the hollow hole is octagonal, which easily leads to uneven filling of the sound insulation material in the hollow hole and gaps between the two hollow holes, thereby reducing the thermal insulation and sound insulation effects of the hollow floor structure.

[0007] The utility model achieves the above-mentioned purpose through the following technical solutions: a thermal insulation and sound insulation recycled concrete composite hollow floor structure, comprising: a prefabricated hollow floor, the rear end of the prefabricated hollow floor is fixedly connected to the recycled concrete floor, the rear end of the recycled concrete floor is fixedly connected to the waterproof layer, and the front end of the waterproof layer is fixedly connected to the leveling layer; a thermal insulation and sound insulation component, the thermal insulation and sound insulation component is arranged inside the prefabricated hollow floor; wherein, the thermal insulation and sound insulation component includes hollow holes distributed in equal rows on the top of the prefabricated hollow floor, the inner wall of the hollow hole is concave in a cylindrical shape, the inner wall of the hollow hole is fixedly connected to a distribution rack, the surface of the distribution rack is provided with through holes distributed in equal rows, and the inner wall of the prefabricated hollow floor is embedded with a thermal insulation and sound insulation board. By using the hollow holes with cylindrical depressions on the inner walls, the thermal insulation and sound insulation materials are evenly filled in the inner walls of the hollow holes, reducing the aggregation of the thermal insulation and sound insulation materials in certain areas of the hollow holes. By using the thermal insulation and sound insulation panels, the inner walls of the prefabricated hollow floor slabs are fully insulated and soundproofed, preventing noise from passing through the gap between the two hollow holes. Compared with the existing thermal insulation and sound insulation materials, which are unevenly filled in the hollow holes and have gaps between the two hollow holes, the thermal insulation and sound insulation materials in this method can be evenly distributed and the prefabricated hollow floor slabs can be fully insulated and soundproofed, ensuring the thermal insulation and sound insulation effect of the recycled concrete composite hollow floor slab structure. By using the material distribution rack and the through holes, the thermal insulation and sound insulation materials in the hollow holes are well supported, which facilitates the sinking and sliding of the thermal insulation and sound insulation materials in different directions, thereby enhancing the stability of the thermal insulation and sound insulation materials in the hollow holes.

[0008] Preferably, the rear end of the thermal insulation and sound insulation board is fixedly connected with connection blocks distributed in equal rows, and the surface of the connection block is embedded and installed in the front end of the recycled concrete floor slab.

[0009] Preferably, the inner wall of the precast hollow-core floor slab is fixedly connected to fixed rods distributed in an even row, and the surfaces of these fixed rods are fixedly connected to reinforcing rods. The surface of one side of the fixed rods is fixedly connected to the thermal insulation and sound insulation board and the inner wall of the recycled concrete floor slab in sequence, and the surface of one side of the reinforcing rods is fixedly connected to the inner wall of the recycled concrete floor slab. The connection blocks, reinforcing rods, and fixed rods enhance the tensile strength of the precast hollow-core floor slab and the recycled concrete floor slab.

[0010] Preferably, the material distribution rack is in a cross shape as a whole and is an aluminum alloy component.

[0011] Preferably, the inner wall of the through hole is concave in an elliptical shape.

[0012] Preferably, the reinforcing rod, the fixing rod and the connecting block are all low alloy steel components.

[0013] Preferably, the surface of the reinforcing rod is fixedly connected with an anti-slip block, and the surface of the anti-slip block is spirally progressive. The spirally progressive anti-slip block improves the fastening of the reinforcing rod to the prefabricated hollow floor slab or recycled concrete floor slab.

[0014] The beneficial effects of the utility model are:

[0015] 1. The hollow holes with cylindrical recesses in the inner wall enable the thermal insulation and sound insulation materials to be evenly filled in the inner wall of the hollow hole, thereby reducing the aggregation of the thermal insulation and sound insulation materials in certain areas of the hollow hole. The thermal insulation and sound insulation board achieves comprehensive thermal insulation and sound insulation of the inner wall of the prefabricated hollow floor slab, thereby preventing noise from passing through the gap between the two hollow holes. Compared with the existing thermal insulation and sound insulation materials, which are unevenly filled in the hollow holes and have gaps between the two hollow holes, the thermal insulation and sound insulation materials in this method can be evenly distributed and comprehensively insulate and soundproof the prefabricated hollow floor slab, thereby ensuring the thermal insulation and sound insulation effect of the recycled concrete composite hollow floor slab structure. The material distribution rack and the through hole achieve good support for the thermal insulation and sound insulation materials in the hollow hole, thereby facilitating the sinking and side sliding of the thermal insulation and sound insulation materials in different directions, thereby enhancing the stability of the thermal insulation and sound insulation materials in the hollow hole.

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] When implementing: Figure 1-4 As shown, a thermal insulation and sound insulation recycled concrete composite hollow floor structure includes: a prefabricated hollow floor 1, the rear end of the prefabricated hollow floor 1 is fixedly connected to a recycled concrete floor 2, the rear end of the recycled concrete floor 2 is fixedly connected to a waterproof layer 3, and the front end of the waterproof layer 3 is fixedly connected to a leveling layer 4; a thermal insulation and sound insulation component 5, which is arranged inside the prefabricated hollow floor 1; wherein, the thermal insulation and sound insulation component 5 includes hollow holes 51 distributed in equal rows on the top of the prefabricated hollow floor 1, the inner wall of the hollow hole 51 is concave in a cylindrical shape, and a distribution rack 52 is fixedly connected to the inner wall of the hollow hole 51, and the surface of the distribution rack 52 is provided with through holes 53 distributed in equal rows, and the inner wall of the prefabricated hollow floor 1 is embedded with a thermal insulation and sound insulation board 56, the inner wall of the through hole 53 is concave in an elliptical shape, and the distribution rack 52 is cross-shaped as a whole, and the distribution rack 52 is an aluminum alloy component.

[0024] The waterproof layer 3 is a polyurethane waterproof coating component, and the leveling layer 4 is a fine stone concrete component. The recycled concrete floor slab 2 and the prefabricated hollow floor slab 1 are made of recycled construction waste such as waste concrete and bricks. The hollow hole 51 is filled with an insulation layer of glass wool and modified polypropylene. The sound absorption coefficient of the glass wool is 0.85 at a sound frequency of 1000HZ. The thermal conductivity of the modified polypropylene insulation layer is 0.030-0.040W / (m·k). The front end of the prefabricated hollow floor slab 1 is fixedly connected to a cement mortar plaster layer. The cement mortar plaster layer is prepared with sulphoaluminate cement and has a thickness of 2-3mm.

[0025] During the production of the thermal insulation and sound insulation recycled concrete composite hollow floor slab, recycled concrete raw materials are poured into the hollow floor slab mold. After a series of operations such as vibration, the prefabricated hollow floor slab 1 and the recycled concrete floor slab 2 are solidified, and then the hollow hole 51 with a cylindrical inner wall is filled with thermal insulation material. Since the inner wall of the hollow hole 51 is symmetrical in all directions, the thermal insulation and sound insulation material is evenly diffused in the hollow hole 51. The cross-shaped material distribution rack 52 divides the hollow hole 51 into four areas. The material distribution rack 52 and the through hole 53 enable the thermal insulation and sound insulation material to more effectively cover the entire hole wall during the filling process, thereby avoiding the thermal insulation and sound insulation material from gathering in a certain area of the hollow hole 51.

[0026] like Figure 2As shown, the rear end of the heat-insulating and sound-insulating board 56 is fixedly connected with connection blocks 57 distributed in equal rows, and the surface of the connection block 57 is embedded and installed in the front end of the recycled concrete floor slab 2.

[0027] like Figure 3 As shown, the inner wall of the prefabricated hollow floor 1 is fixedly connected with fixing rods 55 distributed in an equal row, and the surface of the fixing rods 55 is fixedly connected with reinforcing rods 54. The surface of one side of the fixing rods 55 is fixedly connected to the thermal insulation and sound insulation board 56 and the inner wall of the recycled concrete floor 2 in sequence, and the surface of the reinforcing rods 54 on one side is fixedly connected to the inner wall of the recycled concrete floor 2. The surface of the reinforcing rods 54 is fixedly connected with anti-sliding blocks 58, and the surface of the anti-sliding blocks 58 is spirally progressive. The reinforcing rods 54, the fixing rods 55 and the connecting blocks 57 are all low-alloy steel components.

[0028] When the utility model is used, after the heat-insulating sound-proofing board 56, the connecting block 57, the reinforcing rod 54 and the fixing rod 55 are placed in the corresponding positions in the hollow floor mold, the recycled concrete raw materials are poured into the hollow floor mold, and after a series of operations such as vibration and tamping, the prefabricated hollow floor 1 and the recycled concrete floor 2 are solidified, and the heat-insulating sound-proofing material is filled into the hollow hole 51 with a cylindrical shape in the inner wall. Because the inner wall of the hollow hole 51 is symmetrical in all directions, the heat-insulating sound-proofing material is evenly diffused in the hollow hole 51, and the cross-shaped material dividing frame 52 divides the hollow hole 51 into four areas. The hollow hole 51 is provided with a plurality of hollow holes 51 and a plurality of hollow holes 51 respectively. The hollow hole 51 is provided with a plurality of hollow holes 51 and a plurality of hollow holes 51 respectively.
