Description

Technical Field

[0001] This utility model relates to the field of floor slabs, and more specifically, to a floor slab structure. Background Technology

[0002] With the continuous development of my country's construction industry, building industrialization has become the future direction of construction development. Precast composite floor slabs, manufactured in factories, are a new type of product that can replace cast-in-place floor slabs and roofs in high-rise buildings. They offer advantages such as reducing the cumbersome procedures of formwork erection and dismantling, and shortening the construction cycle.

[0003] Composite floor slabs are assembled monolithic floor slabs made by stacking precast slabs and cast-in-place reinforced concrete layers. During construction, a crane is needed to lift the precast slabs to the construction location, but the existing precast slabs are relatively large in size and weight, making transportation and hoisting quite troublesome.

[0004] Therefore, a new solution is needed to address this problem. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a floor slab structure that solves the problem of inconvenient installation of existing floor slab structures.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: The embodiments of this application provide a floor slab structure, including multiple precast slab components, which are assembled to form a precast slab layer. A casting layer is provided on the precast slab layer. Each precast slab component includes an upper precast slab and a lower precast slab. An upper groove is provided on the upper precast slab, and a lower groove is provided on the lower precast slab. The upper and lower precast slabs are assembled vertically, and the upper groove and the lower groove enclose an air cavity. The system also includes a connecting component that can connect two adjacent precast slab components.

[0007] In one embodiment, an upper connecting groove is longitudinally provided on the upper precast slab, and a lower connecting groove is provided on the lower precast slab, which communicates with the upper connecting groove. A connecting rod is provided in the upper connecting groove, one end of which is interference-fitted with the lower connecting groove, and the other end of which extends upward out of the upper connecting groove. Both the upper and lower connecting grooves are designed to taper from top to bottom. The upper bottom surface of the lower connecting groove is equal to the lower bottom surface of the upper connecting groove. A grouting gap is formed between the connecting rod and the sidewalls of the upper connecting groove and at least part of the lower connecting groove.

[0008] In one embodiment, a positioning component is provided at the top of the connecting rod, the positioning component including a first positioning rod and a second positioning rod, the first positioning rod and the second positioning rod being cross-connected.

[0009] In one embodiment, the connecting assembly includes a connecting plate, and the lower precast slab includes a front side, a rear side, a left side, and a right side. Each of the front side, rear side, left side, and right side is provided with a connecting rib. The connecting rib includes a first rib and a second rib that bends upward along the first rib. A tapered block with a diameter that gradually increases from top to bottom is provided on the second rib. Two through holes are provided through the connecting plate, and the tapered blocks of two adjacent lower precast slabs pass through the two through holes respectively.

[0010] In one embodiment, wire mesh is provided in both the upper and lower precast slabs, and reinforcing bars are provided through the front, rear, left, and right sides of the lower precast slab. The reinforcing bars on the front and rear sides are located on different straight lines, and the reinforcing bars on the left and right sides are located on different straight lines.

[0011] In summary, this utility model has the following beneficial effects: By setting the precast slab assembly to include an upper precast slab and a lower precast slab, the upper and lower precast slabs are relatively lightweight, making hoisting and transportation more convenient. By setting upper and lower grooves on the upper and lower precast slabs respectively, when the upper and lower precast slabs are aligned and spliced, the upper and lower grooves form an air cavity. After the pouring layer is completed, the floor slab contains an air cavity, making the floor slab lighter. The presence of the air cavity also gives the floor slab good sound insulation and heat preservation effects. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] like Figures 1 to 4 As shown, an embodiment of this application provides a floor slab structure, including multiple precast slab components 1, which are assembled to form a precast slab layer. A casting layer is provided on the precast slab layer. Each precast slab component 1 includes an upper precast slab 11 and a lower precast slab 12. The upper precast slab 11 is provided with an upper groove, and the lower precast slab 12 is provided with a lower groove 122. The upper precast slab 11 and the lower precast slab 12 are assembled vertically, and the upper groove and the lower groove 122 enclose an air cavity. The application also includes a connecting component that can connect two adjacent precast slab components 1.

[0019] During operation, the crane first lifts the lower precast slab 12 to the construction position, then lifts the upper precast slab 11 to the construction position, aligns the upper precast slab 11 with the lower precast slab 12, and then pours the concrete to form the pouring layer.

[0020] The above structure is designed by setting the precast slab assembly 1 to include an upper precast slab 11 and a lower precast slab 12. The upper precast slab 11 and the lower precast slab 12 are relatively light, making hoisting and transportation convenient. By setting upper grooves and lower grooves 122 on the upper precast slab 11 and the lower precast slab 12 respectively, when the upper precast slab 11 and the lower precast slab 12 are aligned and spliced, the upper grooves and the lower grooves 122 form an air cavity. After the pouring layer is completed, the floor slab contains an air cavity, making the floor slab lighter. The presence of the air cavity also gives the floor slab good sound insulation and heat preservation effects.

[0021] In this embodiment, an upper connecting groove 112 is longitudinally provided on the upper precast slab 11, and a lower connecting groove 121 connected to the upper connecting groove 112 is provided on the lower precast slab 12. A connecting rod 2 is provided in the upper connecting groove 112. One end of the connecting rod 2 is interference-fitted with the lower connecting groove 121, and the other end of the connecting rod 2 extends upward out of the upper connecting groove 112. Both the upper connecting groove 112 and the lower connecting groove 121 are designed to taper from top to bottom. The upper bottom surface of the lower connecting groove is equal to the lower bottom surface of the upper connecting groove. A grouting gap is formed between the connecting rod 2 and the sidewalls of the upper connecting groove 112 and at least part of the lower connecting groove 121.

[0022] Specifically, radial grooves are provided on the upper precast slab 11 and the lower precast slab 12 along the radial direction of the upper connecting groove 112 and the lower connecting groove 121, respectively. When pouring, the slurry fills the upper connecting groove, the lower connecting groove and the radial groove, which makes the floor slab more stable and stronger.

[0023] During operation, the upper precast slab 11 and the lower precast slab 12 are first aligned, so that the upper connecting groove 112 and the lower connecting groove 121 are aligned. Then, the connecting rod 2 is inserted into the upper connecting groove 112 and inserted downward into the lower connecting groove 121, with the bottom of the connecting rod 2 having an interference fit with the lower connecting groove 121. Since both the upper connecting groove 112 and the lower connecting groove 121 are designed to contract from top to bottom, a grouting gap is formed between the connecting rod 2 and the side wall of the upper connecting groove 112 and part of the side wall of the lower connecting groove 121. When pouring, the grout fills the grouting gap, making the connection between the connecting rod 2 and the upper precast slab 11 and the lower precast slab 12 tight and with good overall integrity.

[0024] The above structure is designed so that the upper connecting groove 112 and the lower connecting groove 121 are designed to taper from top to bottom, and a connecting rod 2 is provided so that a grouting gap is formed between the upper connecting groove 112 and the lower connecting groove 121 and the connecting rod 2. This allows the slurry during pouring to enter the grouting gap and connect the connecting rod 2 tightly with the upper precast slab 11 and the lower precast slab 12, resulting in better overall integrity of the floor slab.

[0025] In this embodiment, a positioning component 21 is provided on the top of the connecting rod 2. The positioning component 21 includes a first positioning rod 211 and a second positioning rod 212, and the first positioning rod 211 and the second positioning rod 212 are cross-connected.

[0026] The above structure is designed by setting a positioning component 21 on the top of the connecting rod 2, and setting the positioning component 21 to include a first positioning rod 211 and a second positioning rod 212 that are perpendicular to each other. During the pouring, the concrete will pour the positioning component 21 into it, which will make the stability of the pouring layer better. At the same time, when the mud is poured, the cross-shaped positioning component 21 will be pressed down to prevent the connecting rod 2 from protruding.

[0027] In this embodiment, the connecting assembly includes a connecting plate 3, and the lower precast plate 12 includes a front side, a rear side, a left side, and a right side. Each of the front side, rear side, left side, and right side is provided with a connecting rib 4. The connecting rib 4 includes a first rib 41 and a second rib 42 that bends upward along the first rib 41. The second rib 42 is provided with a tapered block 421 whose diameter gradually increases from top to bottom. The connecting plate 3 is provided with two through holes, and the tapered blocks of two adjacent lower precast plates 12 pass through the two through holes respectively.

[0028] During operation, after the precast slab components 1 are arranged neatly, the connecting ribs 4 of two adjacent precast slab components 1 are close together. At this time, the two through holes on the connecting plate 3 correspond to the two conical blocks 421 on the two precast slab components 1 respectively. The connecting plate 3 can be a steel plate. Use a tool such as a hammer to knock the connecting plate 3 downwards so that the conical blocks 421 pass through the through holes. It should be noted that the conical blocks 421 are made of metal. The through holes can be set to be slightly smaller than the lower part of the conical blocks 421 so that the connection between the connecting plate 3 and the two precast slab components 1 is stable.

[0029] The above structure is designed by setting connecting ribs 4 on the precast slab assembly 1, setting conical blocks 421 on the connecting ribs 4, setting connecting plates 3, and setting through holes on the connecting plates 3 corresponding to the conical blocks 421 of two adjacent precast slab assemblies 1, so that the conical blocks 421 can penetrate the connecting plates 3, and the through holes are adapted to the bottom of the conical blocks 421. When the conical blocks 421 pass through the through holes, there is a certain resistance, which makes the connection of the two precast slab assemblies 1 by the connecting plates 3 stable and fast, without the need to use steel bars 5 to tie the two precast slab assemblies 1, thus improving work efficiency.

[0030] In this embodiment, wire mesh is provided in both the upper precast slab 11 and the lower precast slab 12. Reinforcing bars 5 are provided through the front, rear, left and right sides of the lower precast slab 12. The reinforcing bars 5 on the front and rear sides are located on different straight lines, and the reinforcing bars 5 on the left and right sides are located on different straight lines.

[0031] During operation, when the precast slab assembly 1 is arranged, the reinforcing bars 5 of two adjacent precast slab assemblies 1 intersect each other, resulting in high strength of the floor slab after pouring.

[0032] Specifically, the pouring layer encloses each precast slab assembly 1.

[0033] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
