Description

Technical Field

[0001] The utility model relates to the technical field of plate fixing in building construction, in particular to a pre-buried plate fixing part capable of significantly improving earthquake resistance. Background Art

[0002] Embedded plate fixings are components that are pre-embedded in walls and structural concrete during construction to fix various plates (such as prefabricated floor slabs, wall panels, etc.). These components usually include embedded parts, anchor bolts, welded parts, etc., which can firmly fix the plates in the wall or concrete structure, thereby ensuring the stability and safety of the entire structure. They are widely used in the construction industry, especially in large-scale engineering projects such as high-rise buildings, bridges, and tunnels.

[0003] The existing traditional embedded plate fixings have insufficient seismic performance when natural disasters such as earthquakes occur due to unreasonable design structure, improper material selection or poor construction specifications. They are easy to loosen, fall off or even break under strong vibrations, causing the plates connected to the fixings to shift and crack, and in severe cases even cause the overall destruction of the building structure. Summary of the invention

[0004] The utility model aims to provide a pre-embedded plate fixing part to address the defects of the prior art, which can significantly improve the seismic resistance of the plate connected to the fixing part.

[0005] In order to achieve the above purpose, the utility model can adopt the following technical solutions:

[0006] The embedded plate fixing member of the utility model comprises a clamping and fixing unit clamped at the four corners of the rectangular embedded plate, a first seismic buffer unit is connected to the lower surface of each of the clamping and fixing units, and two of the first seismic buffer units located on each short side of the rectangular embedded plate are connected as a whole through a second seismic buffer unit;

[0007] The clamping and fixing unit comprises an upper clamping plate and a lower clamping plate arranged in parallel, one side of the upper clamping plate and the lower clamping plate are connected as a whole through a connecting plate, so that a clamping groove adapted to clamp the rectangular embedded plate is formed between the upper and lower clamping plates, and a pair of fixing screws are vertically penetrated on the upper and lower clamping plates;

[0008] The first anti-seismic buffer unit comprises a buffer plate arranged parallel to and below the lower clamping plate, the lower end of the fixing screw passes through the buffer plate, a damping spring is sleeved on the fixing screw between the buffer plate and the lower clamping plate, the upper end of the damping spring is in contact with the lower surface of the lower clamping plate, and the lower end thereof is fixedly connected to the buffer plate through a connecting washer;

[0009] The second anti-seismic buffer unit includes a bearing plate that connects the two buffer plates on the same short side of the rectangular embedded plate into one, the bearing plate is flush with the buffer plate, and a thin-walled box is arranged on the bearing plate along its length direction, and the thin-walled box is filled with shock-absorbing gel.

[0010] Specifically, the thin-walled box is a rectangular glass box with a thickness of 1 to 3 mm. A plurality of pairs of filling tubes are evenly spaced along the length direction of the two long side walls of the thin-walled box, and the axes of each pair of the filling tubes are perpendicular to the long side walls of the thin-walled box. The filling tubes have a fluid replenishing cavity connected to the inner cavity of the thin-walled box, and the fluid replenishing cavity is filled with a supplementary gel; wherein the shock-absorbing gel and the supplementary gel are both polyvinyl alcohol gel.

[0011] Furthermore, a pressure block for crushing the thin-walled box is arranged on the bottom surface of each lower clamping plate, and the pressure block has a first position located above the thin-walled box when the lower clamping plate is not subjected to force, and a second position for crushing the thin-walled box when the lower clamping plate is pressed downward. In addition, a shock absorber is also arranged on the buffer plate directly below the pressure block.

[0012] The advantage of the utility model is that the four corners of the rectangular embedded plate can be easily clamped and fixed by four groups of clamping and fixing units, so that the rectangular embedded plate can be fixed while realizing continuous splicing and assembly with other rectangular embedded plates; in addition, the first seismic buffer unit and the second seismic buffer unit arranged on the clamping and fixing unit can use the damping spring to effectively offset the vibration force when natural disasters such as earthquakes occur, and can crush the thin-walled box when the vibration intensity is large, so that the shock-absorbing gel inside it is filled in the wall or structural concrete, absorbing and dissipating the vibration energy, reducing the impact of vibration on the clamping and fixing unit, reducing structural damage, and improving the seismic performance of the entire embedded plate fixing part and the rectangular embedded plate.

[0017] The following is a detailed description of an embodiment of the present invention in conjunction with the accompanying drawings. This embodiment is implemented on the premise of the technical solution of the present invention, and a detailed implementation method and a specific operation process are given, but the protection scope of the present invention is not limited to the following embodiment.

[0018] like Figure 1-4 As shown, the embedded plate fixing member described in the utility model includes four groups of clamping and fixing units clamped at the four corners of the rectangular embedded plate 100, and a group of first seismic buffer units are connected to the lower surface of each clamping and fixing unit, and the two first seismic buffer units located on each short side of the rectangular embedded plate 100 are connected as a whole through a group of second seismic buffer units.

[0019] Specifically, the clamping and fixing unit includes an upper clamping plate 1 and a lower clamping plate 2 arranged in parallel, and both the upper clamping plate 1 and the lower clamping plate 2 are rectangular plates, and the spacing between them should be consistent with the plate thickness of the rectangular embedded plate 100; one side of the upper clamping plate 1 and the lower clamping plate 2 is connected as a whole through a connecting plate 3, so that a clamping groove 4 that can fit and clamp the rectangular embedded plate 100 is formed between the upper clamping plate 1 and the lower clamping plate 2. In addition, a pair of fixing screws 5 for fixing in the wall or structural concrete of the construction project are also vertically penetrated on the upper clamping plate 1 and the lower clamping plate 2, and the lower end of the fixing screw 5 is a spike end. When the two fixing screws 5 are installed, one passes through the rectangular embedded plate 100 clamped in the clamping groove 4, and the other is located outside the rectangular embedded plate 100, so that it can cooperate with the part of the upper clamping plate 1 and the lower clamping plate 2 extending outside the rectangular embedded plate 100 to connect another embedded plate, so as to realize the continuous splicing and assembly of the rectangular embedded plate 100.

[0020] The first seismic buffer unit includes a buffer plate 6 arranged parallel to the lower clamp plate 2. At this time, the lower end of the fixing screw 5 should pass through the buffer plate 6, and the damping spring 7 is respectively installed on the two fixing screws 5 between the buffer plate 6 and the lower clamp plate 2. The upper end of the damping spring 7 is in contact with the lower surface of the lower clamp plate 2, and a connecting washer 8 is provided at its lower end. The connecting washer 8 is an annular washer, which is fixed to the top surface of the buffer plate 6 after being put on the fixing screw 5.

[0021] The second seismic buffer unit includes a bearing plate 9 which connects two buffer plates 6 on the same short side of the rectangular embedded plate 100 as one body. The bearing plate 9 is flush with the buffer plate 6, and a weight-reducing groove may be provided in the middle thereof. A thin-walled box 10 is arranged on the bearing plate 9 along its length direction. The thin-walled box 10 is a rectangular glass box with a thickness of 1 to 3 mm, which can be easily crushed when subjected to force. A plurality of pairs of filling tubes 11 are evenly spaced along the length direction on the two long side walls of the thin-walled box 10, and the axes of each pair of filling tubes 11 are perpendicular to the long side walls of the thin-walled box 10. The filling tubes 11 have a liquid infusion cavity connected to the inner cavity of the thin-walled box 10. In addition, the thin-walled box 10 is filled with shock-absorbing gel, and the filling tube 11 is filled with supplementary gel. Both the shock-absorbing gel and the supplementary gel are polyvinyl alcohol gel. When the thin-walled box 10 is squeezed, it will break itself, causing the shock-absorbing gel filled therein to flow out. As the shock-absorbing gel flows out, the supplementary gel in the filling tube 11 will also flow out and be filled in the wall or structural concrete of the construction project. Therefore, when the wall or structural concrete is subjected to high-intensity vibration caused by an earthquake, it can absorb and dissipate energy, reduce the impact of the vibration on the clamping and fixing unit, and thereby reduce the structural damage of the rectangular embedded plate 100.

[0022] Furthermore, a pressing block 12 for crushing the thin-walled box 10 can be arranged on the bottom surface of each lower clamping plate 2, and a shock absorber 13 can be arranged on the buffer plate 6 directly below the pressing block 12; the pressing block 12 has a first position located above the thin-walled box 10 when the lower clamping plate 2 is not under force, and a second position for crushing the thin-walled box 10 when the lower clamping plate 2 is pressed downward. When the wall or structural concrete of the construction project is subjected to a relatively small vibration, the thin-walled box 10 can be crushed by the pressing block 12, and when the wall or structural concrete of the construction project is subjected to a relatively large vibration, the downward pressure of the pressing block 12 can be further offset by the shock absorber 13.

[0023] The four groups of clamping and fixing units can easily clamp and fix the four corners of the rectangular embedded plate 100, ensuring that the rectangular embedded plate 100 is fixed while also realizing continuous splicing and assembly with other embedded plates; in addition, the first seismic buffer unit and the second seismic buffer unit arranged on the clamping and fixing unit can also use the damping spring 7 to effectively offset the vibration force when natural disasters such as earthquakes occur, and can crush the thin-walled box 10 when the vibration intensity is large, so that the shock-absorbing gel therein and the supplementary gel in the filling tube 11 are filled in the wall or structural concrete of the construction project, absorbing and dissipating the vibration energy, reducing the impact of vibration on the clamping and fixing unit, reducing structural damage, and improving the seismic performance of the entire embedded plate fixing and the rectangular embedded plate 100.
