Technical Field

[0001] This utility model belongs to the field of building technology, and specifically relates to a crack-resistant structural device for large-area floors in factory buildings. Background Technology

[0002] In modern industrial plant construction, the application of large-area floors is becoming increasingly widespread. However, due to the large loads borne by factory floors and the influence of factors such as temperature changes and concrete shrinkage, cracks are prone to appear. Floor cracks not only affect the aesthetics of the factory building but may also lead to a decrease in the floor's load-bearing capacity, affecting the normal operation of equipment within the factory.

[0003] Currently, commonly used crack-resistant measures such as setting expansion joints and adding crack-resistant fibers can alleviate the occurrence of cracks to a certain extent, but they still cannot fundamentally solve the problem of cracking in large areas of factory floors. Therefore, a crack-resistant structural device for large areas of factory floors is proposed. Utility Model Content

[0004] In view of the problems mentioned in the background art, the purpose of this utility model is to provide a crack-resistant structural device for large-area floors in factory buildings, so as to solve the problems mentioned in the background art.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

A rubber dispersion plate is provided on one side of the fiber-reinforced concrete layer, and multiple rubber dispersion plates are provided. A first steel sheet and a second steel sheet are provided on the side of the rubber dispersion plate away from the fiber-reinforced concrete layer. An assembly sleeve is slidably connected to the outer surface of the first steel sheet, and multiple assembly sleeves are provided. An assembly base plate is fixedly connected to one side of each assembly sleeve. Positioning mechanisms are provided on both sides of the assembly sleeve away from the assembly base plate. An assembly top plate is provided on one side of the assembly base plate. A fixing component is provided between the assembly base plate and the assembly top plate.

[0007] As a preferred technical solution, the first steel sheet and the second steel sheet are arranged perpendicularly to each other, and multiple second steel sheets are provided on the first steel sheet.

A transmission screw block is threadedly connected to the outer surface of the transmission screw. A positioning rod is fixedly connected to one side of the transmission screw block. One side of the positioning rod movably abuts against one side of the first steel plate. A torsion wheel is fixedly connected to the side of the transmission screw extending out of the assembly sleeve. Shaft plates are fixedly connected inside both sides of the assembly sleeve, and the transmission screw is rotatably connected to the shaft plates.

[0009] As a preferred technical solution, guide holes are provided on both sides of the assembly sleeve, and one side of the positioning rod slides through the guide holes.

[0010] As a preferred technical solution, the fixing component includes a first screw groove, which is formed inside both sides of the mounting top plate. A fixing screw is threaded into the inside of the first screw groove. A second screw groove is formed inside both sides of the mounting bottom plate. One side of the fixing screw passes through the first screw groove and is threaded into the second screw groove.

[0011] As a preferred technical solution, rubber strips are fixedly connected to one side of both the assembly base plate and the assembly top plate, and multiple rubber strips are provided.

[0014] Secondly, by setting an assembly sliding sleeve and positioning mechanism on the first steel sheet, the position of the second steel sheet can be flexibly adjusted according to the actual stress conditions of different areas of the floor, thereby adjusting the spacing and layout of the steel mesh, accurately adapting to the stress distribution characteristics of each area, and making the crack-resistant structure more targeted and adaptable.

[0021] Example

[0022] refer to Figures 1 to 5 This embodiment describes a crack-resistant structural device for large-area factory floors, comprising a fiber-reinforced concrete layer 1. A rubber dispersion plate 2 is provided on one side of the fiber-reinforced concrete layer 1, and multiple rubber dispersion plates 2 are provided. A first steel sheet 3 and a second steel sheet 4 are provided on the side of the rubber dispersion plate 2 away from the fiber-reinforced concrete layer 1. Multiple assembly sleeves 5 are slidably connected to the outer surface of the first steel sheet 3. An assembly base plate 6 is fixedly connected to one side of each assembly sleeve 5. Positioning mechanisms 8 are provided on both sides of the assembly sleeve 5 away from the assembly base plate 6. The assembly base plate 6 is located on one side... The assembly includes a top plate 7, a bottom plate 6, and a concrete injection hole on one side of the top plate 7, which facilitates the integration of the fiber concrete layer 1 into the joint and reinforces the joint. A fixing component 9 is provided between the bottom plate 6 and the top plate 7. A rubber dispersion plate 2 is laid on the first steel plate 3 and the second steel plate 4, and then the fiber concrete layer 1 is injected. The steel mesh is filled along the gap. The fiber concrete layer 1 can inhibit early shrinkage cracks, the rubber dispersion plate 2 can buffer stress, and the steel mesh composed of the first steel plate 3 and the second steel plate 4 enhances the overall strength. The three work together to construct a basic crack-resistant system.

[0023] refer to Figure 2 The first steel sheet 3 and the second steel sheet 4 are arranged perpendicularly to each other, and multiple second steel sheets 4 are provided on the first steel sheet 3; the first steel sheets 3 and the second steel sheets 4 arranged perpendicularly to each other and distributed in multiple ways form a crisscross grid, which can disperse stress in both horizontal and vertical directions.

[0024] refer to Figure 4The positioning mechanism 8 includes a transmission screw 62, which is rotatably connected to both sides of the assembly sleeve 5. A transmission screw block 63 is threaded onto the outer surface of the transmission screw 62. A positioning rod 61 is fixedly connected to one side of the transmission screw block 63, and a rubber sheet is fixed to the end of the positioning rod 61. One side of the positioning rod 61 movably abuts against one side of the first steel plate 3. A torsion wheel 64 is fixedly connected to the side of the transmission screw 62 extending out of the assembly sleeve 5. The outer surface of the torsion wheel 64 is also provided with multiple anti-slip grooves. Shaft plates 66 are fixedly connected to the interior of both sides of the assembly sleeve 5, and the transmission screw 62 is rotatably connected to the shaft plates 66. Guide holes 65 are provided on both sides of the 5. The positioning rod 61 slides through the guide hole 65 on one side. After the positioning mechanism 8 is set up and the assembly sleeve 5 is adjusted to the position of the second steel piece 4, the torsion wheel 64 is rotated to drive the transmission screw 62 to rotate. The rotation of the transmission screw 62 causes the transmission screw block 63 to move along the transmission screw 62, thereby driving the positioning rod 61 to slide in the guide hole 65 until the positioning rod 61 abuts against the first steel piece 3, thus locking the position of the assembly sleeve 5. This design can change the spacing and layout of the steel mesh, and can accurately adjust the distribution of steel bars according to the actual stress conditions of different areas of the floor. Compared with traditional welding, the operation is more convenient.

[0025] refer to Figure 5 The fixing component 9 includes a first screw groove 91, which is formed inside both sides of the mounting top plate 7. A fixing screw 92 is threaded inside the first screw groove 91. A second screw groove 93 is formed inside both sides of the mounting base plate 6. One side of the fixing screw 92 passes through the first screw groove 91 and is threadedly connected to the second screw groove 93. By setting the fixing component 9, the fixing screw 92 passes through the first screw groove 91 and is screwed into the second screw groove 93. By tightening the fixing screw 92, the mounting base plate 6 and the mounting top plate 7 are tightly connected and fixed to prevent the second steel plate 4 from falling off.

[0026] refer to Figure 5 Rubber strips 10 are fixedly connected to one side of the inner side of the assembly base plate 6 and the assembly top plate 7, and multiple rubber strips 10 are provided. The rubber strips 10 are in contact with the second steel sheet 4. By setting multiple rubber strips 10, the installation position of the second steel sheet 4 can be stabilized, avoiding slippage and affecting the structural stability.

[0027] Operating principle and advantages: After adjusting the position of the mounting sleeve 5 on the first steel plate 3, rotate the torsion wheel 64 to drive the transmission screw 62 to rotate. The rotation of the transmission screw 62 causes the transmission screw block 63 to move along the transmission screw 62, thereby driving the positioning rod 61 to slide in the guide hole 65 until the positioning rod 61 abuts against the first steel plate 3, completing the locking of the mounting sleeve 5 position. Then, place the second steel plate 4 into the mounting base plate 6 and place the second steel plate 4 into the groove of the mounting base plate 6. Attach the mounting top plate 7 to the mounting base plate 6, pass the fixing screw 92 through the first threaded groove 91, and screw it into the second threaded groove 93. Tighten the fixing screw 92 to lock the position of the mounting sleeve 5. The base plate 6 and the top plate 7 are tightly connected and fixed to prevent the second steel plate 4 from falling off. Then, the rubber dispersion plate 2 is laid, followed by the injection of fiber concrete material to form the fiber concrete layer 1. The fiber concrete layer 1 inhibits early shrinkage cracks, the rubber dispersion plate 2 provides elastic stress buffering, and the steel mesh enhances the overall strength. The three work together to improve the crack resistance of the floor from multiple dimensions and effectively reduce the occurrence of cracks. In particular, the combination of multiple rubber dispersion plates 2 and steel mesh can quickly and evenly disperse the concentrated stress on the floor to a larger area, avoiding local stress concentration that leads to cracks and significantly improving the floor's ability to resist stress damage.
