Description

Technical Field

[0001] This utility model relates to the field of building materials technology, and in particular to a shock-absorbing lightweight high-strength floor slab. Background Technology

[0002] Floor slabs are horizontal load-bearing components in buildings that separate upper and lower floors. They are mainly used to bear floor loads (such as the weight of people, furniture, and equipment) and transfer them to walls, beams, columns, or foundations. Their design usually needs to take into account performance such as strength, rigidity, sound insulation, fire resistance, and heat insulation.

[0003] A search revealed Chinese patent publication number CN209538489U, which relates to a lightweight, high-strength, sound-insulating precast floor slab. It includes an inner reinforcing mesh, with a concrete body cast around the mesh. The concrete body comprises a rectangular intermediate body, with a retaining plate integrally formed on the upper-middle part of one side of the intermediate body and a support plate integrally formed on the lower-middle part of the other side. A sealing groove extending along the length of the support plate is provided on the top of the support plate, allowing for the installation of a sealing strip. This utility model provides a lightweight, high-strength, sound-insulating precast floor slab. Compared to existing precast floor slabs, by integrally forming the retaining plate and support plate on both sides of the intermediate body and setting a sealing groove on the support plate, the connection between two adjacent precast floor slabs after horizontal assembly is tighter. Furthermore, by setting a sealing strip within the sealing groove and performing secondary grouting in the joint gap, the overall structural strength and sound insulation performance of the floor slab are directly improved.

[0004] Existing floor slabs are usually made of simple concrete. Due to the single material and uniform density distribution, the fracture surface will be large when the floor slab is subjected to compression and failure. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a shock-absorbing lightweight high-strength floor slab, which aims to improve the problem that existing floor slabs are usually made of simple concrete pouring, resulting in a large fracture surface when the floor slab is subjected to compression and failure.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a shock-absorbing lightweight high-strength floor slab, comprising a floor slab body, a precast slab attached to the upper surface of the floor slab body, a groove formed inside the floor slab body, a connecting block fixedly connected inside the precast slab, a connecting block 2 slidably connected to the outer wall of the connecting block 1, the outer wall of the connecting block 2 slidably connected to the inside of the precast slab, a connecting plate fixedly connected to the upper surface of the connecting block 2, a sliding component disposed inside the connecting block 2, a support block slidably connected to the outer wall of the sliding component, the outer wall of the support block fixedly connected to the inside of the connecting block 2, a spring disposed on the outer wall of the support block, and the outer wall of the spring disposed on the outer wall of the sliding component.

[0007] The above technical solution involves: firstly, lightweight high-strength material is poured into the floor slab through a groove, with reinforcing bars distributed dispersed beneath the lightweight material and concentrated at the intervals between the lightweight materials; then, a connecting plate is spliced ​​with the precast slab, causing the sliding component to slide on the outer wall of connecting block one. Simultaneously, the sliding component, in conjunction with connecting block two, compresses the spring. When the sliding component reaches the appropriate position, the spring propels it into the interior of connecting block one, thus fixing the connecting plate. By pouring lightweight high-strength material, the uneven distribution of reinforcing bars, and fixing the connecting plate, the weight of the floor slab is reduced while also providing some protection, preventing breakage.

[0008] As a further description of the above technical solution: The sliding assembly includes a sliding column, the outer wall of which is slidably connected to the interior of the connecting block two, a fixed disk is fixedly connected to the outer wall of the sliding column, the outer wall of the sliding column is disposed on the outer wall of the connecting block one, and the outer wall of the spring is disposed on the outer wall of the fixed disk.

[0009] Through the above technical solution: when the sliding column slides on the outer wall of the connecting block one, it will drive the fixed plate to move, and further cooperate with the connecting block two to compress the spring.

[0010] As a further description of the above technical solution: The connecting block 1 has a hole inside, and the sliding column is slidably connected to the inside of the connecting block 1 through the hole.

[0011] Through the above technical solution, the sliding column slides into the interior of the connecting block one through the hole, further fixing the connecting plate.

[0012] As a further description of the above technical solution: The upper surface of the connecting plate is provided with a protective plate, which is composed of a buffer layer and a reinforcing component, with the lower surface of the buffer layer attached to the upper surface of the reinforcing component.

[0013] The above technical solution improves the buffer absorption of external forces by cooperating with the buffer layer and reinforcing components.

[0014] As a further description of the above technical solution: The reinforcing component includes a reinforcing layer, the upper surface of which is attached to the lower surface of the buffer layer, and a waterproof layer is attached to the lower surface of the reinforcing layer. The lower surface of the waterproof layer is disposed on the upper surface of the connecting plate.

[0015] The above technical solution uses a buffer layer to cushion external forces, preventing them from directly impacting the floor slab and causing it to break.

[0016] As a further description of the above technical solution: The second connecting block has a groove inside, and the first connecting block is slidably connected to the inside of the second connecting block through the groove.

[0017] The above technical solution achieves the splicing of precast slabs and connecting plates by sliding the connecting block one inside the groove two.

[0018] As a further description of the above technical solution: The interior of the floor slab is filled with lightweight, high-strength materials.

[0019] The above technical solution involves filling the pre-reserved grooves inside the floor slab with lightweight, high-strength materials to reduce the overall weight of the floor slab.

[0020] As a further description of the above technical solution: The lower surface of the connecting plate is attached to the upper surface of the precast slab, and the outer wall of the sliding component is disposed on the outer wall of the connecting block one.

[0021] The above technical solution involves the sliding component and the connecting block working together to fix the connecting plate and the precast slab, with the connecting plate providing a certain level of protection for the floor slab itself.

[0022] This utility model has the following beneficial effects: 1. In this utility model, firstly, lightweight high-strength material is filled into the groove of the floor slab body, then the floor slab body is sealed with a precast slab, and then the connecting plate is attached to the precast slab, thereby driving the sliding column to slide on the outer wall of the connecting block, and cooperating with the support block to compress the spring. When the sliding column slides to the position of the hole opened inside the connecting block, the spring releases its elastic force to push the sliding column into the interior of the connecting block, so that the connecting plate is fixed on the precast slab. By filling with lightweight material and fixing the connecting plate, the weight of the floor slab body is reduced while protecting it, thereby improving the reliability of the floor slab body during use.

[0023] 2. In this utility model, a protective plate is set on the upper surface of the connecting plate. The protective plate is composed of a buffer layer, a reinforcing layer and a waterproof layer. Through the combined action of the buffer layer, the reinforcing layer and the waterproof layer, the protection efficiency of the floor slab body is improved, ensuring that the floor slab body will not break after long-term use.

[0026] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0027] Reference Figure 1 , Figure 2 and Figure 3 An embodiment of this utility model is provided: a shock-absorbing lightweight high-strength floor slab, including a floor slab body 1, a precast slab 2 attached to the upper surface of the floor slab body 1, a groove 3 inside the floor slab body 1, a connecting block 4 fixedly connected inside the precast slab 2, a connecting block 6 slidably connected to the outer wall of the connecting block 4, the outer wall of the connecting block 6 slidably connected to the inside of the precast slab 2, a connecting plate 7 fixedly connected to the upper surface of the connecting block 6, a sliding component 8 provided inside the connecting block 6, a support block 9 slidably connected to the outer wall of the sliding component 8, the outer wall of the support block 9 fixedly connected to the inside of the connecting block 6, a spring 10 provided on the outer wall of the support block 9, and the outer wall of the spring 10 provided on the outer wall of the sliding component 8; Specifically, lightweight high-strength material is filled into the interior of the floor slab body 1 through groove 3. The steel bars in the floor slab body 1 are distributed dispersedly below the lightweight material and concentrated in the gaps between the lightweight materials. The precast slab 2 is used to close the top of the floor slab body 1. Then, the lower surface of the connecting plate 7 is attached to the upper surface of the precast slab 2, which further drives the sliding component 8 to slide on the outer wall of the connecting block 4. While sliding, the spring 10 is compressed. When the sliding component 8 slides to the appropriate position, the spring 10 releases its own elasticity and pushes the sliding component 8 into the interior of the connecting block 4, thereby fixing the connecting plate 7. By adding lightweight high-strength material, the special distribution of steel bars, and fixing the connecting plate 7, a good support and protection for the floor slab body 1 is achieved, preventing the floor slab body 1 from breaking.

[0028] Reference Figure 4 , Figure 6 and Figure 7 The sliding component 8 includes a sliding column 81, the outer wall of which is slidably connected to the inside of the second connecting block 6, and a fixed disk 82 is fixedly connected to the outer wall of the sliding column 81. The outer wall of the sliding column 81 is disposed on the outer wall of the first connecting block 4, and the outer wall of the spring 10 is disposed on the outer wall of the fixed disk 82. A hole 5 is provided inside the first connecting block 4, and the sliding column 81 is slidably connected to the inside of the first connecting block 4 through the hole 5. Specifically, when connecting block 1 4 slides inside connecting block 2 6, it will drive sliding column 81 to move. When sliding column 81 moves, it will drive fixed plate 82 to move through the fixing action of sliding column 81 and fixed plate 82, further compressing spring 10. When connecting block 1 4 slides to the appropriate position, spring 10 will reset fixed plate 82, and further push sliding column 81 into the interior of connecting block 1 4 through hole 5.

[0029] Reference Figure 1 and Figure 5 The upper surface of the connecting plate 7 is provided with a protective plate 11, which is composed of a buffer layer 12 and a reinforcing component 13. The lower surface of the buffer layer 12 is attached to the upper surface of the reinforcing component 13. Specifically, through the cooperation between the buffer layer 12 and the reinforcing component 13, the external forces on the connecting plate 7 are buffered to a certain extent, so as to avoid the external forces from acting directly on the floor slab body 1 and causing the floor slab body 1 to break.

[0030] Reference Figure 5 , Figure 7 and Figure 8The reinforcing component 13 includes a reinforcing layer 131, the upper surface of which is attached to the lower surface of the buffer layer 12, and a waterproof layer 132 attached to the lower surface of the reinforcing layer 131. The lower surface of the waterproof layer 132 is disposed on the upper surface of the connecting plate 7. A groove 14 is provided inside the connecting block 2 6, and the connecting block 1 4 is slidably connected to the inside of the connecting block 2 6 through the groove 14. Specifically, the reinforcing layer 131 is used to improve the overall strength of the protective plate 11, the buffer layer 12 is made of silicone rubber, which can buffer the external forces on the protective plate 11, and the waterproof layer 132 is used to isolate external moisture and prevent moisture from entering the interior of the floor slab body 1 and causing corrosion to the floor slab body 1.

[0031] Reference Figure 1 , Figure 6 and Figure 7 The interior of the floor slab body 1 is filled with lightweight and high-strength materials; the lower surface of the connecting plate 7 is attached to the upper surface of the precast slab 2, and the outer wall of the sliding component 8 is set on the outer wall of the connecting block 4. Specifically, the overall weight of the floor slab body 1 is reduced by filling the interior with lightweight and high-strength materials. The connecting plate 7 is used to provide a certain degree of protection for the floor slab body 1 and prevent external forces from acting directly on the floor slab body 1.

[0032] Working principle: First, lightweight high-strength material is filled into the interior of the floor slab body 1 through groove 3. Then, the floor slab body 1 is sealed by the precast slab 2. The lower surface of the connecting plate 7 is attached to the upper surface of the precast slab 2, which further drives the sliding column 81 to slide on the outer wall of the connecting block 4. When the sliding column 81 slides on the outer wall of the connecting block 4, it will drive the fixed plate 82 to move. During the movement, it cooperates with the support block 9 to compress the spring 10. After the sliding column 81 slides a certain distance on the outer wall of the connecting block 4, the spring 10 will release its own elasticity, which will further push the sliding column 81 into the interior of the connecting block 4 through the hole 5, thereby fixing the connecting plate 7 to the upper surface of the precast slab 2. By pouring lightweight high-strength material and fixing the connecting plate 7, the overall weight of the floor slab body 1 is reduced while also providing a certain degree of protection for the floor slab body 1. By setting a protective plate 11 on the upper surface of the connecting plate 7, the protective plate 11 is composed of a buffer layer 12, a reinforcing layer 131, and a waterproof layer 132. The buffer layer 12 is made of silicone rubber, which can buffer external forces due to its excellent toughness and resilience. The reinforcing layer 131 is used to improve the overall strength of the protective plate 11 and prevent it from breaking. Then, the waterproof layer 132 isolates external moisture and prevents it from entering the floor slab body 1. Through the combined effect of the buffer layer 12, the reinforcing layer 131, and the waterproof layer 132, the overall protection efficiency of the floor slab body 1 is improved.

[0033] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
