Description

Technical Field

[0001] The invention relates to the technical field of building engineering, and in particular to an earthquake-resistant reinforcement device for connecting a building floor slab with a wall. Background Art

[0002] Building floor and wall connections are an important part of building design and construction, and their main purpose is to ensure the stability, bearing capacity and safety of the structure.

[0003] The existing building floor wall connection is to hang the floor on the wall, use steel bars to pass through the connection holes reserved on the floor to connect and fix the floor. However, since the steel bars need to be tied manually, it is time-consuming and labor-intensive, and the stability between the floor slabs is poor. When an earthquake occurs, the floor slabs are easily shaken and displaced, which is quite dangerous.

[0004] Therefore, a seismic reinforcement device for building floor slab wall connections has been developed that can quickly connect and fix floor slabs while ensuring the stability between the floor slabs and preventing the floor slabs from vibrating and shifting. Summary of the invention

[0005] In order to overcome the shortcomings of existing building floor and wall connections, in which steel bars need to be manually tied, which is time-consuming and labor-intensive, and the stability between the floors is poor. When an earthquake occurs, the floors are easily caused to shake and shift, which is relatively dangerous. The present invention provides a seismic reinforcement device for building floor and wall connections that can quickly connect and fix the floors, while ensuring the stability between the floors and avoiding vibration and shifting of the floors.

[0006] The technical solution is: an anti-seismic reinforcement device for the connection of building floor slabs and walls, including walls, floor slabs, reinforcers, a stabilizing mechanism and a top mechanism. Floor slabs are placed on the upper sides of the left and right parts of the wall, and reinforcers are clamped on the upper sides of the front and back parts of the wall. The reinforcers all pass through the floor slabs. The reinforcers are provided with a stabilizing mechanism that can enhance the stability between the reinforcers and the wall. The reinforcers are also provided with a top mechanism that can lock the floor slabs.

[0007] As a further preferred scheme, the stabilizing mechanism includes a supporting shaft, an eccentric wheel, a lifting frame and a first spring. The lower part of the reinforcer is connected to the left and right supporting shafts, and the supporting shafts are rotatably connected to the eccentric wheels. The left and right parts of the reinforcer are slidably connected to the lifting frames. The lifting frames are connected to the connected reinforcers with the first springs, and the lifting frames are movably connected to the adjacent eccentric wheels. When the floor presses down on the reinforcer, the floor squeezes the lifting frame to move downward, the first spring is stretched, and the lifting frame moves downward, pushing the eccentric wheel to rotate on the supporting shaft, so that the eccentric wheel contacts the wall, thereby enhancing the stability of the reinforcer.

[0008] As a further preferred solution, the top mechanism includes a rotating plate and a third connecting shaft. The third connecting shaft is connected to the upper sides of the left and right parts of the reinforcer. The rotating plate is rotatably connected to the third connecting shaft. After the floor is placed on the reinforcer, the rotating plate on the third connecting shaft is rotated so that the rotating plate is located on the upper side of the floor and contacts it.

[0009] As a further preferred scheme, it also includes a spreading mechanism, which includes a support frame, a support foot, a first connecting rod, a sliding frame, a second connecting rod, a first connecting shaft and a linear spring. The middle part of the reinforcer is connected to the support frame, and the left and right parts of the support frame are slidably connected to the front and rear support feet. The support feet are rotatably connected with the first connecting rod, and the sliding frames are rotatably connected to the two adjacent first connecting rods. The sliding frames are slidably connected to the adjacent support frames, and the sliding frames are rotatably connected to the second connecting rods. The two adjacent second connecting rods are rotatably connected to the first connecting shaft, and the sliding frames are connected to the adjacent support frames with linear springs. When the floor presses down on the reinforcer, the first connecting shaft is pushed downward, so that the second connecting rod rotates, pushing the sliding frames to move away from each other, and the linear springs are squeezed and contracted, so that the first connecting rod rotates and pushes the support feet to spread outward and contact the wall.

[0010] As a further preferred scheme, it also includes a reinforcement mechanism, which includes a guide rod, a connecting arm, a sliding arm, a second spring and a rotating frame. The lower sides of the left and right parts of the reinforcer are connected to guide rods, the lower parts of the guide rods are slidably connected to connecting arms, the connecting arms are connected to adjacent lifting frames, the upper parts of the guide rods are slidably connected to sliding arms, the sliding arms are connected to adjacent connecting arms with second springs, the upper part of the reinforcer is rotatably connected to left and right rotating frames, the rotating frames are in contact and cooperation with adjacent sliding arms, and when the lifting frame moves downward, the connecting arms are driven downward, and the sliding arms are driven downward by the action of the second spring, so that the sliding arms trigger the rotating frame to rotate, so that the convex surface of the rotating frame contacts the floor.

[0011] As a further preferred scheme, it also includes a contact mechanism, which includes a connecting plate, a buffer pad and a sliding rod. The front and rear parts of the first connecting shaft are connected to connecting plates, the upper sides of the connecting plates are connected to buffer pads, and the lower sides of the left and right parts of the connecting plates are connected to sliding rods. The sliding rods are slidingly connected to adjacent reinforcers. When the floor slab is pressed down onto the first connecting shaft, it contacts the buffer pad, thereby squeezing the connecting plate to move downward. The connecting plate is guided by the sliding rod so that the connecting plate moves vertically downward. When the connecting plate moves downward, it drives the first connecting shaft to move downward.

[0012] As a further preferred solution, the buffer pads are all made of rubber.

[0013] As a further preferred solution, grooves are formed on the buffer pads.

[0014] As a further preferred scheme, it also includes an anti-jump mechanism, which includes a rotating plate, a second connecting shaft and a torsion spring. The front and rear sides of the reinforcer are connected to two left and right second connecting shafts, and the second connecting shafts are rotatably connected to the rotating plates. The rotating plates are connected to the second connecting shafts with torsion springs. When the floor is pressed down on the reinforcer, the rotating plate is squeezed to move inward, and the rotating plate is pressed against the floor through the force of the torsion spring. When the floor moves up and down, friction is generated between the rotating plate and the floor, so that the rotating plate blocks the floor.

[0015] As a further preferred solution, the lower side of the rotating plate is a wedge structure.

[0016] The present invention has the following advantages: 1. The present invention fixes the floor slab by passing the reinforcer through the reserved hole on the floor slab, and then rotates the rotating plate on the third connecting shaft so that the rotating plate is located on the upper side of the floor slab and contacts it, thereby achieving the effect of being able to quickly connect and fix the floor slab, while ensuring the stability between the floor slabs and avoiding vibration and displacement of the floor slabs.

[0017] 2. The present invention pushes the first connecting shaft downward while pressing the floor slab on the reinforcer, so that the second connecting rod rotates, pushing the sliding frame to move away from each other, and then the first connecting rod rotates to push the supporting feet to open outward and contact the wall, thereby achieving the effect of enhancing the stability of the reinforcer on the wall and preventing the movement of the reinforcer.

[0018] 3. The present invention drives the connecting arm to move downward while the lifting frame moves downward, and drives the sliding arm to move downward through the action force of the second spring, so that the sliding arm triggers the rotating frame to rotate, so that the convex surface of the rotating frame contacts the floor, thereby achieving the effect of increasing the friction between the reinforcer and the floor and improving the stability of the floor.

[0019] 4. In the present invention, when the plate is pressed down onto the first connecting shaft, it contacts the buffer pad, thereby squeezing the connecting plate to move downward, and guiding the connecting plate through the sliding rod so that the connecting plate moves downward vertically. When the connecting plate moves downward, the first connecting shaft is driven to move downward, thereby ensuring that the floor slab squeezes the first connecting shaft downward and avoiding the failure of the floor slab to contact the first connecting shaft due to defects.

[0020] 5. When the floor slab is pressed down on the reinforcer, the present invention squeezes the rotating plate to move inward, and the rotating plate is pressed against the floor slab by the force of the torsion spring. When the floor slab moves up and down, friction is generated between the rotating plate and the floor slab, so that the rotating plate blocks the floor slab, thereby achieving the effect of strengthening the stability of the floor slab and preventing the floor slab from moving up and down.

DETAILED DESCRIPTION

[0034] In order to make the purpose, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings. It is hereby stated that the directional terms such as up, down, left, right, front, back, inside, outside, etc. that appear or will appear in the text of the present invention are only based on the accompanying drawings of the present invention, and are not specific limitations of the present invention.

[0035] A seismic reinforcement device for connecting floor slabs and walls of a building, such as Figure 1 and Figure 2 As shown, it includes a wall 1, a floor 2, a reinforcer 3, a stabilizing mechanism 4 and a top mechanism 9. Floor slabs 2 are placed on the upper sides of the left and right parts of the wall 1, and reinforcers 3 are clamped on the upper sides of the front and back parts of the wall 1. The reinforcers 3 pass through the floor slab 2. The reinforcers 3 are provided with a stabilizing mechanism 4, and the reinforcers 3 are also provided with a top mechanism 9.

[0036] like Figure 2-Figure 4 As shown, the stabilizing mechanism 4 includes a support shaft 41, an eccentric wheel 42, a lifting frame 43 and a first spring 44. The lower part of the reinforcer 3 is connected to the left and right support shafts 41, and the support shafts 41 are rotatably connected to the eccentric wheels 42. The left and right parts of the reinforcer 3 are slidably connected to the lifting frames 43. The lifting frames 43 are connected to the first spring 44 with the connected reinforcer 3, and the lifting frames 43 are movably connected to the adjacent eccentric wheels 42.

[0037] like Figure 1 , Figure 2 and Fig.12 As shown, the top mechanism 9 includes a rotating piece 91 and a third connecting shaft 92 . The upper sides of the left and right parts of the reinforcer 3 are both connected to the third connecting shaft 92 , and the rotating piece 91 is rotatably connected to the third connecting shaft 92 .

[0038] When using the present invention, first place the floor 2 on the wall 1, and fix the floor 2 by passing the reinforcer 3 through the reserved hole on the floor 2. When the floor 2 is pressed down on the reinforcer 3, the floor 2 squeezes the lifting frame 43 to move downward, and the first spring 44 is stretched. While the lifting frame 43 moves downward, it pushes the eccentric wheel 42 to rotate on the support shaft 41, so that the eccentric wheel 42 contacts the wall 1, thereby enhancing the stability of the reinforcer 3. After the floor 2 is placed on the reinforcer 3, the rotating piece 91 on the third connecting shaft 92 is rotated so that the rotating piece 91 is located on the upper side of the floor 2 and contacts it, thereby achieving the effect of quickly connecting and fixing the floor 2, while ensuring the stability between the floor slabs 2 and avoiding vibration and displacement of the floor slabs 2.

[0039] like Figure 2 , Figure 5 and Figure 6As shown, it also includes a spreading mechanism 5, which includes a support frame 51, a support foot 52, a first connecting rod 53, a sliding frame 54, a second connecting rod 55, a first connecting shaft 56 and a linear spring 57. The middle part of the reinforcer 3 is connected to the support frame 51, and the left and right parts of the support frame 51 are slidably connected to the front and rear support feet 52, and the support feet 52 are rotatably connected to the first connecting rod 53, and the sliding frame 54 is rotatably connected between the two adjacent first connecting rods 53. The sliding frame 54 is slidably connected to the adjacent support frames 51, and the sliding frame 54 is rotatably connected to the second connecting rod 55, and the first connecting shaft 56 is rotatably connected between the two adjacent second connecting rods 55, and the sliding frame 54 is connected to the adjacent support frames 51 with a linear spring 57.

[0040] By using the expansion mechanism 5 of the present device, the stability of the reinforcer 3 on the wall 1 can be enhanced. When the floor slab 2 presses down on the reinforcer 3, the first connecting shaft 56 is pushed downward, so that the second connecting rod 55 rotates, pushing the sliding frame 54 to move away from each other, and the linear spring 57 is squeezed and contracted, so that the first connecting rod 53 rotates and pushes the supporting foot 52 to expand outward and contact the wall 1, thereby enhancing the stability of the reinforcer 3 on the wall 1 and preventing the reinforcer 3 from moving.

[0041] like Figure 2 and Figure 7 As shown, it also includes a reinforcement mechanism 6, which includes a guide rod 61, a connecting arm 62, a sliding arm 63, a second spring 64 and a rotating frame 65. The lower sides of the left and right parts of the reinforcer 3 are connected to the guide rod 61, the lower part of the guide rod 61 is slidably connected to the connecting arm 62, the connecting arm 62 is connected to the adjacent lifting frame 43, the upper part of the guide rod 61 is slidably connected to the sliding arm 63, the sliding arm 63 is connected to the adjacent connecting arm 62 with a second spring 64, the upper part of the reinforcer 3 is rotatably connected to the left and right rotating frames 65, and the rotating frames 65 are in contact and cooperate with the adjacent sliding arms 63.

[0042] The reinforcement mechanism 6 of the device can improve the stability of the floor 2. When the lifting frame 43 moves downward, it drives the connecting arm 62 to move downward. The sliding arm 63 is driven downward by the force of the second spring 64, so that the sliding arm 63 triggers the rotating frame 65 to rotate, so that the convex surface of the rotating frame 65 contacts the floor 2, thereby increasing the friction between the reinforcer 3 and the floor 2 and improving the stability of the floor 2.

[0043] like Figure 2 , Figure 8 and Fig. 9As shown, it also includes a contact mechanism 7, which includes a connecting plate 71, a buffer pad 72 and a sliding rod 73. The front and rear parts of the first connecting shaft 56 are connected to the connecting plates 71, and the upper sides of the connecting plates 71 are connected to the buffer pads 72. The buffer pads 72 are made of rubber material to facilitate buffering of the floor 2. The buffer pads 72 are provided with grooves to improve the buffering performance. The lower sides of the left and right parts of the connecting plate 71 are connected to the sliding rods 73, and the sliding rods 73 are slidably connected to the adjacent reinforcers 3.

[0044] The contact mechanism 7 of the device can ensure that the floor 2 squeezes the first connecting shaft 56 to move downward. When the floor 2 is pressed down onto the first connecting shaft 56, it contacts the buffer pad 72, and then squeezes the connecting plate 71 to move downward. The connecting plate 71 is guided by the sliding rod 73 so that the connecting plate 71 moves downward vertically. When the connecting plate 71 moves downward, it drives the first connecting shaft 56 to move downward, thereby ensuring that the floor 2 squeezes the first connecting shaft 56 to move downward, and avoiding the floor 2 being unable to contact the first connecting shaft 56 due to defects.

[0045] like Figure 2 , Fig.10 and Fig.11 As shown, it also includes an anti-jump mechanism 8, which includes a rotating plate 81, a second connecting shaft 82 and a torsion spring 83. The front and rear sides of the reinforcer 3 are connected to the left and right second connecting shafts 82. The second connecting shafts 82 are rotatably connected to the rotating plates 81. The lower sides of the rotating plates 81 are wedge structures for blocking the floor 2. Torsion springs 83 are connected between the rotating plates 81 and the second connecting shafts 82 connected thereto.

[0046] The anti-jump mechanism 8 of the device can prevent the floor 2 from jumping. When the floor 2 is pressed down on the reinforcer 3, the rotating plate 81 is squeezed to move inward, and the rotating plate 81 is pressed against the floor 2 through the force of the torsion spring 83. When the floor 2 moves up and down, friction is generated between the rotating plate 81 and the floor 2, so that the rotating plate 81 blocks the floor 2, thereby enhancing the stability of the floor 2 and preventing the floor 2 from moving up and down.

These descriptions are only for explaining the principles of the embodiments of the present invention and cannot be interpreted in any way as limiting the protection scope of the embodiments of the present invention.
