Description

Technical Field

[0001] The utility model relates to the technical field of building sound insulation, and more specifically, to a building design sound insulation floor slab. Background Art

[0002] Building floor slabs are the load-bearing structures between floors. They divide vertical buildings into several layers and transfer the load between layers to the columns along the beams. Floor slabs are mostly processed in factories and then installed on buildings through prefabricated structures.

[0003] Patent publication number CN220954110U discloses an assembled, multi-ribbed soundproof floor. It comprises a top and bottom structure, with a multi-ribbed structure interposed between them via a truss structure. Multiple soundproofing boxes are embedded within the multi-ribbed structure. These boxes are arranged in an array and filled with soundproofing cotton. The boxes also serve as the formwork support system for the multi-ribbed structure.

[0004] After being installed in a building, the sound insulation effect at the joint gaps of this patent is relatively weak, there is no means to strengthen the sound insulation, and the use of a sound insulation box affects the effectiveness of the sound insulation cotton. Utility Model Content

[0005] In order to overcome the above-mentioned shortcomings, the present invention aims to provide a sound insulation floor slab designed for building, which can enhance sound insulation at the joints and give full play to the effect of sound insulation rock wool.

[0006] A sound-insulating floor slab of architectural design comprises: vertically placed positioning columns; a lower concrete layer arranged at the bottom of the positioning columns; a sound-insulating keel layer arranged above the lower concrete layer, wherein sound-insulating rock wool is embedded in the sound-insulating keel; an upper concrete layer arranged above the sound-insulating keel layer; a caulking layer arranged in gaps between adjacent upper concrete layers; and a leveling layer arranged above the caulking layer and the upper concrete layer.

[0007] Furthermore, the positioning column passes through the lower concrete layer, the sound insulation keel layer, the upper concrete layer and the caulking layer in sequence, and the top surface of the positioning column is lower than or parallel to the top surface of the leveling layer.

[0008] Furthermore, floor slab steel bars are provided in the lower concrete layer and the upper concrete layer, and the floor slab steel bars are distributed in a single layer and in two directions.

[0009] Furthermore, a connecting hole is provided on the side wall of the sound insulation keel layer, and the concrete in the lower concrete layer and the concrete in the upper concrete layer are connected as a whole through the connecting hole.

[0010] Furthermore, a partition is provided in the sound insulation keel layer, and the partition divides the sound insulation keel layer into a plurality of storage areas, and the sound insulation rock wool is filled in the storage areas.

[0011] Furthermore, a plurality of grooves are provided on both upper and lower side walls of the partition, and a fixing plate is mounted on the grooves, and the fixing plate and the partition are cross-distributed.

[0012] Furthermore, the upper and lower fixing plates are connected by positioning nails, and the positioning nails pass through the sound insulation rock wool.

[0013] Furthermore, sound insulation boards are provided on the upper and lower parts of the sound insulation keel layer, and the sound insulation boards cover the surface of the sound insulation rock wool, and the positioning columns penetrate the sound insulation boards.

[0014] Furthermore, the caulking layer is made of sound insulation felt, and both sides of the caulking layer are tightened by the positioning columns.

[0015] Furthermore, the material of the leveling layer is mortar or fine stone concrete.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] ① When prefabricating the floor slab, place the positioning columns in the prefabricated mold at equal intervals, then lay the lower concrete layer to fix the positioning columns. Before the lower concrete solidifies, adjust the top surface of the positioning columns to the predetermined height of the floor slab to facilitate subsequent height unification. This eliminates the need to determine the elevation when laying the leveling layer, thereby improving the construction efficiency of the subsequent leveling layer.

[0018] ② The caulking layer uses sound insulation felt. When in use, tighten both sides of the caulking layer and then put it on the positioning column so that the caulking layer covers the connecting gap, thereby enhancing the sound insulation effect at the gap.

[0019] ③ The fixed plates and partitions are distributed crosswise. The fixed plates limit the movement of the sound-insulating rock wool. At the same time, the fixed plates can withstand the pressure brought by the floor slab. When the sound vibration is transmitted to the partitions and fixed plates, the sound-insulating rock wool can absorb the sound energy, so that most of the sound energy cannot continue to be transmitted downward, thereby achieving the sound insulation effect.

[0025] 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.

[0026] like Figure 1 、 Figure 2 As shown, a sound insulation floor slab of architectural design includes: a vertically placed positioning column 1; a lower concrete layer 2 provided at the bottom of the positioning column 1; a sound insulation keel layer 3 provided above the lower concrete layer 2, and sound insulation rock wool 31 is embedded in the sound insulation keel layer 3; an upper concrete layer 4 provided above the sound insulation keel layer 3; a caulking layer 5 provided in the gap between adjacent upper concrete layers 4; and a leveling layer 6 provided above the caulking layer 5 and the upper concrete layer 4.

[0027] Positioning columns 1 sequentially penetrate the lower concrete layer 2, the sound insulation keel layer 3, the upper concrete layer 4, and the caulking layer 5. The top surface of the positioning columns 1 is lower than or parallel to the top surface of the leveling layer 6. During floor slab prefabrication, the positioning columns 1 are placed in the prefabricated mold at equal intervals. The lower concrete layer 2 is then laid to secure the positioning columns 1. Before the lower concrete layer solidifies, the top surface of the positioning columns 1 is adjusted to the predetermined height of the floor slab. This facilitates subsequent height uniformity and eliminates the need to determine the elevation when laying the leveling layer 6, improving the efficiency of subsequent leveling layer 6 construction.

[0028] Floor slab reinforcement 7 is installed within the lower concrete layer 2 and upper concrete layer 4, distributed bidirectionally in a single layer. These layers withstand the internal pressure of the floor. The reinforcement 7 of adjacent slabs is connected during installation, forming a single unit. The reinforcement 7 imparts tensile strength to the concrete, ultimately ensuring the floor's basic load-bearing capacity.

[0029] like Figure 3As shown, the side wall of the sound insulation keel layer 3 is provided with a connecting hole 32, and the concrete in the lower concrete layer 2 and the upper concrete layer 4 are connected as a whole through the connecting hole 32. When the concrete in the upper concrete layer 4 is poured, the concrete will flow into the lower concrete layer 2 through the connecting hole 32. The connecting hole 32 is located on the outside of the positioning column 1. After the upper concrete layer 4 is poured, the concrete will wrap around the periphery of the sound insulation keel layer 3. The sound insulation keel itself is made of steel. The sound insulation keel layer 3 also provides some compressive and tensile resistance in the concrete, making the strength of the floor higher. At the same time, the concrete wraps the sound insulation rock wool 31, isolating the sound insulation rock wool 31 from the outside world, ensuring the service life of the sound insulation rock wool 31, and also making the integrity of the floor stronger, so that the floor has a sound insulation function while strengthening the strength of the floor.

[0030] A partition 33 is provided in the sound insulation keel layer 3. The partition 33 is made of steel plate. The partition 33 divides the sound insulation keel layer 3 into several storage areas. The storage areas are rectangular in shape. The sound insulation rock wool 31 is filled in the storage areas. The sound insulation rock wool 31 uses finished rock wool blocks to reduce the flying of rock wool fibers. Before laying the sound insulation rock wool 31, the sound insulation rock wool 31 is cut to a width slightly larger than the spacing between the partitions 33, so that the partitions 33 can clamp the sound insulation rock wool 31 in the storage area.

[0031] Several grooves are provided on the upper and lower side walls of the partition 33, and a fixing plate 34 is mounted on the groove. The upper and lower surfaces of the sound insulation rock wool 31 are flush with the bottom of the groove to prevent the sound insulation rock wool 31 from affecting the installation of the fixing plate 34. The fixing plate 34 and the partition 33 are cross-distributed. The fixing plate 34 limits the movement of the sound insulation rock wool 31. At the same time, the fixing plate 34 can withstand the pressure brought by the floor part. When the sound vibration is transmitted to the partition 33 and the fixing plate 34, the sound insulation rock wool 31 can absorb the sound energy, so that most of the sound energy cannot continue to be transmitted downward, thereby achieving the sound insulation effect.

[0032] To ensure a tighter connection between the fixing plate 34 and the sound-insulating rock wool 31, the upper and lower fixing plates 34 are connected by positioning pins 341, which penetrate the sound-insulating rock wool 31. The positioning pins 341 are countersunk screws, with nuts connected to the bottom of the positioning pins 341. The nuts are also flush with the fixing plates 34, and the top surfaces of the positioning pins 341 are flush with the top surfaces of the fixing plates 34. The positioning pins 341 press the fixing plates 34 against both sides of the sound-insulating rock wool 31, restricting the position of the fixing plates 34 and simultaneously securing the position of the sound-insulating rock wool 31. This makes the sound-insulating rock wool 31 easy to carry during floor slab production, reduces contact between operators and the sound-insulating rock wool 31, and reduces the risk of allergies.

[0033] Sound insulation panels 8 are provided above and below the sound insulation keel layer 3. These panels cover the surface of the sound insulation rock wool 31. The panels have a rough surface, facilitating a tight connection with the concrete. They prevent cement slurry from flowing into the sound insulation rock wool 31 during concrete pouring. They keep the surface of the sound insulation rock wool 31 clean, preventing cement slurry from hardening the surface, and ensuring the sound insulation effect of the sound insulation rock wool 31. Positioning posts 1 penetrate the panels 8, which have pre-set holes. During installation, the pre-set holes on the panels 8 are inserted into the positioning posts 1 for quick positioning and installation.

[0034] After the floor slab is laid in the building, the caulking layer 5 and the leveling layer 6 are constructed. At this time, the top of the positioning column 1 is still exposed on the surface of the upper concrete layer 4.

[0035] The caulking layer 5 is made of sound insulation felt. When in use, both sides of the caulking layer 5 are tightened and then sleeved on the positioning column 1 so that the caulking layer 5 covers the connecting gap, thereby enhancing the sound insulation effect at the gap.

[0036] The material of the leveling layer 6 is mortar or fine stone concrete. The leveling layer 6 is responsible for filling the floor to a predetermined elevation. The protruding positioning columns 1 act as mortar cakes. When the leveling layer 6 covers the positioning columns 1, the floor reaches the predetermined thickness and elevation.

[0037] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
