Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a joint sealing device. Background Art

[0002] In the construction of the precast concrete (PC) structure system of prefabricated buildings, after the installation of vertical PC components is completed, a joint will be formed between the bottom and the floor slab. Before the high-pressure grouting connection between the internal embedded grouting sleeve and the bottom reserved steel bars, the joint needs to be effectively sealed. In traditional construction sites, mortar is mostly used for sealing, and the sealing methods mainly include mortar bedding sealing and triangular sealing. The mortar bedding sealing process will occupy a 15-20 mm structural surface on each side of the connection node between the vertical PC component of the main structure and the floor slab, reducing the effective bearing cross-sectional size of the load-bearing component, and the mortar bedding sealing position is easily cracked by high pressure, resulting in a decrease in the compactness of the grouting material. The external triangular sealing process greatly increases the usage amount of the sealing mortar, and at the same time, the mortar triangular sealing position needs to be chiseled and cleaned after construction. Content of the Utility Model

[0003] The purpose of the utility model is to provide a joint sealing device to solve the above-mentioned technical problems.

[0004] To achieve the above purpose, the utility model provides the following technical solutions:

[0005] A joint sealing device includes an angle steel installed between the floor slab and the PC component. The angle steel is installed at the gap between the floor slab and the PC component, and a rubber pad is connected to the contact surfaces of the angle steel with the floor slab and the PC component by an adhesive method. The angle steel seals the gap between the floor slab and the PC component through the rubber pad.

[0006] The angle steel is connected with a plurality of limit blocks and a locking mechanism. The limit blocks are located on the upper surface of the angle steel. The locking mechanism is rotatably connected to the limit blocks, and the bottom end is threadedly connected to the floor slab and the PC component. The locking mechanism presses the angle steel on the floor slab and the PC component through the limit blocks.

[0007] As a further scheme of the utility model: The angle steel is of an L-shaped structure, and a plurality of moving grooves are formed on each wing, and the number of the moving grooves is the same as and corresponding to the number of the locking mechanisms. The moving grooves extend along the direction perpendicular to the length of the angle steel, and racks are arranged on the upper surface of the angle steel on both sides of each moving groove.

[0008] As a further scheme of the utility model: The limit block is of a cubic structure, and a tooth groove is formed on the side surface close to the rack. The tooth groove meshes with the rack, and the number of the limit blocks is the same as that of the locking mechanisms.

[0009] As a further solution of the present utility model: a rotation hole is formed in the limit block, the rotation hole is perpendicular to the length direction of the moving groove, and a rotating cylinder is fixedly inserted in the rotation hole.

[0010] As a further solution of the present utility model: the locking mechanism includes a rotating rod rotatably connected in the rotating cylinder, the rotating rod is in clearance fit with the rotating cylinder, and the upper end extends out of the rotating cylinder and is fixedly connected with a turntable. A first limiting disc is sleeved outside the rotating rod, and the first limiting disc is located above the upper surface of the limit block.

[0011] As a further solution of the present utility model: the lower end of the rotating rod extends out of the rotating cylinder, and a second limiting disc is sleeved at the end. A screw rod is fixedly connected to the lower end of the rotating rod, and the screw rod is spirally inserted into the floor slab or the PC component.

[0012] Compared with the prior art, the beneficial effects of the present utility model are:

[0013] In the present utility model, the angle steel is used as a rigid component and does not undergo obvious deformation during use. The rubber pad is regarded as a flexible component and adapts to the unevenness of the floor slab or the PC component through its own elastic deformation during use. The combination of the angle steel and the rubber pad not only combines rigidity and flexibility but also can be reused.

[0014] After the PC component in the present utility model is placed on the floor slab, the gap between the floor slab and the PC component can be sealed by the angle steel and the rubber pad, and the angle steel and the rubber pad are fixed by a plurality of limit blocks and a locking mechanism.

[0015] In the present utility model, when the positions of the holes on the floor slab and the PC component that are threadedly connected to the locking mechanism change, the locking mechanism can move through the moving groove to cope with the holes at different positions, improving the scope of application of the present utility model.

[0016] In the present utility model, after the locking mechanism moves along with the positions of the holes on the floor slab and the PC component, the locking mechanism presses the angle steel against the floor slab and the PC component through the limit block. During this process, the limit block will not slide relative to the angle steel, thus maintaining the stability of the locking mechanism and the limit block. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] Embodiment

[0025] A joint sealing device includes an angle steel 3 installed between the floor slab 1 and the PC component 2. The angle steel 3 is installed at the gap between the floor slab 1 and the PC component 2. A rubber pad 6 is connected to the contact surfaces of the angle steel 3 with the floor slab 1 and the PC component 2 by an adhesive method. The angle steel 3 is used as a rigid component and does not undergo obvious deformation during use. The rubber pad 6 is regarded as a flexible component and adapts to the unevenness of the floor slab 1 or the PC component 2 through its own elastic deformation during use. The combination of the angle steel 3 and the rubber pad 6 not only combines rigidity and flexibility but also can be reused.

[0026] After the PC component 2 is placed on the floor slab 1, the gap between the floor slab 1 and the PC component 2 can be sealed by the angle steel 3 and the rubber pad 6. The angle steel 3 and the rubber pad 6 are fixed by a plurality of limit blocks 4 and a locking mechanism 5.

[0027] As Figures 1 - 5As shown in the figure, in this embodiment: The limiting block 4 is located on the upper surface of the angle steel 3. The locking mechanism 5 is rotatably connected to the limiting block 4, and the bottom end is threadedly connected to the floor slab 1 and the PC member 2. The locking mechanism 5 presses the angle steel 3 against the floor slab 1 and the PC member 2 through the limiting block 4. The angle steel 3 has an L-shaped structure, and a plurality of moving grooves 31 corresponding to the number of the locking mechanisms 5 are provided on each wing. The moving grooves 31 extend along the direction perpendicular to the length of the angle steel 3. The effects achieved by the above components are as follows: The locking mechanism 5 presses the angle steel 3 against the floor slab 1 and the PC member 2 through the limiting block 4; the arrangement of the moving grooves 31 facilitates the locking mechanism 5 to pass through the angle steel 3 and be threadedly connected to the floor slab 1 and the PC member 2; when the positions of the holes on the floor slab 1 and the PC member 2 that are threadedly connected to the locking mechanism 5 change, the locking mechanism 5 can move through the moving grooves 31 to cope with the holes at different positions, improving the application range of the present utility model.

[0028] As Figures 1 - 5 shown in the figure, in this embodiment: Rack teeth 32 are provided on both sides of each moving groove 31 and are located on the upper surface of the angle steel 3. The limiting block 4 has a cubic structure, and a tooth groove 41 is provided on the side surface close to the rack teeth 32. The tooth groove 41 meshes with the rack teeth 32, and the number of the limiting blocks 4 is the same as that of the locking mechanisms 5. The effects achieved by the above components are as follows: The limiting block 4 can be stably fixed at multiple different positions on the upper surface of the angle steel 3 through the meshing of the tooth groove 41 and the rack teeth 32; when the locking mechanism 5 moves along with the positions of the holes on the floor slab 1 and the PC member 2, the locking mechanism 5 presses the angle steel 3 against the floor slab 1 and the PC member 2 through the limiting block 4. During this process, the limiting block 4 will not slide relative to the angle steel 3, thus maintaining the stability of the locking mechanism 5 and the limiting block 4.

[0029] As Figures 1 - 5 shown in the figure, in this embodiment: A rotating hole 42 is provided in the limiting block 4. The rotating hole 42 is perpendicular to the length direction of the moving groove 31, and a rotating cylinder 43 is fixedly inserted in the rotating hole 42. The effects achieved by the above components are as follows: The rotating hole 42 is perpendicular to the length direction of the moving groove 31, which facilitates the subsequent smooth threaded connection of the locking mechanism 5 with the floor slab 1 and the PC member 2 without jamming; the arrangement of the rotating cylinder 43 reduces the wear between the subsequent locking mechanism 5 and the rotating hole 42, improving the service life of the limiting block 4.

[0030] As Figures 1 - 5As shown in the figure, in this embodiment: The locking mechanism 5 includes a rotating rod 51 rotatably connected inside the rotating cylinder 43. The rotating rod 51 has a clearance fit with the rotating cylinder 43, and its upper end extends out of the rotating cylinder 43 and is fixedly connected to the turntable 52. A first limit disk 53 is sleeved outside the rotating rod 51. The first limit disk 53 is located above the upper surface of the limit block 4. The rotating rod 51 extends out of the rotating cylinder 43 at the lower part, and a second limit disk 54 is sleeved at the end. The effects achieved by the above components are as follows: The turntable 52 can drive the rotating rod 51 to rotate; the clearance fit between the rotating rod 51 and the rotating cylinder 43 can reduce the resistance during the rotation of the rotating rod 51 and reduce friction; the settings of the first limit disk 53 and the second limit disk 54 prevent the rotating rod 51 from detaching from the rotating cylinder 43 and maintain the stability of the position of the rotating rod 51.

[0031] As Figures 1 - 5 shown in the figure, in this embodiment: A screw rod 55 is fixedly connected to the lower end of the rotating rod 51. The screw rod 55 is spirally inserted into the floor slab 1 or the PC member 2. The effects achieved by the above components are as follows: When the rotating rod 51 rotates, it drives the screw rod 55 to be spirally inserted into the holes on the floor slab 1 or the PC member 2, realizing the fixed connection between the locking mechanism 5 and the floor slab 1 or the PC member 2.

[0032] The working process of the present utility model is as follows: First, install the angle steel 3 and the rubber pad 6 at the gap between the floor slab 1 and the PC member 2. Then, align the locking mechanism 5 with the holes on the floor slab 1 or the PC member 2. Next, drive the rotating rod 51 to rotate through the turntable 52. The rotating rod 51 drives the screw rod 55 to be spirally inserted into the holes on the floor slab 1 or the PC member 2. During this process, the first limit disk 53 drives the limit block 4 to move towards the rack 32 until the tooth groove 41 meshes with the rack 32, and the limit block 4 presses the angle steel 3 and the rubber pad 6 tightly on the floor slab 1 and the PC member 2;

[0033] When the positions of the holes on the floor slab 1 and the PC member 2 change, drive the locking mechanism 5 to move along the moving groove 31. When the screw rod 55 in the locking mechanism 5 corresponds to the holes on the floor slab 1 and the PC member 2, drive the turntable 52 and repeat the above operations.

[0034] The above is only the preferred specific implementation manner of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and the inventive concept of the present utility model, making equivalent replacements or changes should be covered within the protection scope of the present utility model.
