The template is set together with the two composite slab bodies through a pressing mechanism.

[0006] Furthermore, the connecting mechanism includes two connecting components, which are arranged side by side on the left and right sides of the second side plate and the first side plate.

[0007] Furthermore, the connecting assembly includes a connecting rod disposed behind the first side plate. A first mounting base is disposed at the rear end of the connecting rod. Two first adjusting arms are symmetrically arranged on the upper and lower sides of the first mounting base. The end of the first adjusting arm away from the first mounting base is disposed on a limiting rod. A first adjusting screw is disposed on the front of the second side plate. The first adjusting screw is threadedly connected to a second mounting base. Two second adjusting arms are symmetrically arranged on the upper and lower sides of the second mounting base. The end of the second adjusting arm away from the second mounting base is disposed on the limiting rod.

[0008] Furthermore, the limiting rod is evenly provided with a plurality of limiting holes, and the first adjusting arm and the second adjusting arm are connected in the limiting holes by pins.

[0009] Furthermore, the number of clamping mechanisms is set to two, and the two clamping mechanisms are symmetrically arranged on the front and rear sides of the casting groove.

[0010] Furthermore, the clamping mechanism includes a vertical mounting plate, a fixed clamping plate at the lower part of the vertical mounting plate, a horizontal mounting plate at the upper part of the vertical mounting plate, a second adjusting screw on the horizontal mounting plate, a movable clamping plate matching the fixed clamping plate at the bottom end of the second adjusting screw, a pad on the bottom surface of the movable clamping plate, and a receiving area matching the thickness of the second side plate and the first side plate on the rear side of the pad.

Detailed Implementation

[0021] like Figure 1-5 As shown, a precast composite slab joint support device includes two composite slab bodies 1, which are placed horizontally. The two composite slab bodies 1 form a casting groove 13 on opposite sides. A template 2 is provided at the bottom of the two composite slab bodies 1 and below the casting groove 13. A second side plate 8 and a first side plate 3 are provided on the front and rear sides of the template 2 through a connecting mechanism. The template 2 is set together with the two composite slab bodies 1 through a pressing mechanism 12.

[0022] like Figure 4 As shown, the connecting mechanism includes two connecting components, which are arranged side by side on the left and right sides of the second side plate 8 and the first side plate 3. Each connecting component includes a connecting rod 4, which is connected to the rear of the first side plate 3. The rear end of the connecting rod 4 is connected to a first mounting base 5. Two first adjusting arms 6 are symmetrically hinged to the upper and lower sides of the first mounting base 5. The end of the first adjusting arm 6 away from the first mounting base 5 is hinged to a limiting rod 7. A first adjusting screw 9 is connected to the front of the second side plate 8. A threaded hole matching the first adjusting screw 9 is opened in the middle of the second mounting base 10. The first adjusting screw 9 is threaded into the threaded hole. Two second adjusting arms 11 are symmetrically hinged to the upper and lower sides of the second mounting base 10. The end of the second adjusting arm 11 away from the second mounting base 10 is hinged to the limiting rod 7. Specifically, a plurality of limiting holes are evenly opened on the limiting rod 7. The first adjusting arm 6 and the second adjusting arm 11 are connected to the limiting holes by pins.

[0023] In use, the first side plate 3 is installed on the rear side of the template 2, so that the rear side of the template 2 contacts the front side of the first side plate 3. The first adjusting screw 9 is rotated, and the first adjusting screw 9 drives the second side plate 8 to move to the right, so that the rear side of the second side plate 8 contacts the front side of the template 2. Thus, the template 2, the second side plate 8, and the first side plate 3 surround the bottom, front, and back of the pouring groove 13, which facilitates the later pouring and prevents grout leakage.

[0024] like Figure 2As shown, the number of clamping mechanisms 12 is set to two, and the two clamping mechanisms 12 are symmetrically arranged on the front and rear sides of the casting groove 13.

[0025] like Figure 5 As shown, the clamping mechanism 12 includes a vertical mounting plate 12-1, a fixed clamping plate 12-2 connected to the lower part of the vertical mounting plate 12-1, and a horizontal mounting plate 12-3 connected to the upper part of the vertical mounting plate 12-1. A second adjusting screw 12-5 is threaded onto the horizontal mounting plate 12-3, and the bottom end of the second adjusting screw 12-5 extends below the horizontal mounting plate 12-3. Two guide rods 12-6 are also connected to the top surface of the movable clamping plate 12-4, and the two guide rods 12-6 are arranged on both sides of the second adjusting screw 12-5. The horizontal mounting plate 12-3 has guide holes that match the guide rods 12-6. The bottom end of the second adjusting screw 12-5 is connected to the fixed clamping plate 12-2. A movable clamping plate 12-4 is matched with the clamping plate 12-2. The bottom surface of the movable clamping plate 12-4 is connected to a pad 12-7. The rear side of the pad 12-7 is provided with a receiving area 12-8 that matches the thickness of the second side plate 8 and the first side plate 3. By setting the receiving area 12-8, the portions of the second side plate 8 and the first side plate 3 that are higher than the composite plate body 1 are located within the receiving area 12-8, so that the pad 12-7 can be tightly attached to the top surface of the composite plate body 1. If the thickness of the template 2 is small and the bottom edges of the second side plate 8 and the first side plate 3 are lower than the bottom edge of the template 2, then a pad and a receiving area can also be set on the fixed clamping plate 12-2. If the thickness of the template 2 is large, the surface of the fixed clamping plate 12-2 can be set as a plane.

[0026] In use, the fixed clamping plate 12-2 is brought into contact with the bottom surface of the template 2. The second adjusting screw 12-5 is rotated, and the second adjusting screw 12-5 drives the movable clamping plate 12-4 to descend, so that the pad 12-7 is brought into contact with the top surface of the composite plate body 1, thereby connecting the composite plate body 1 and the template 2 together.

[0027] The usage process of this utility model is as follows:

[0028] First, two composite plate bodies 1 are placed horizontally, forming a casting groove 13 on opposite sides. A template 2 is installed at the bottom of the two composite plate bodies 1. The first side plate 3 is installed on the rear side of the template 2, so that the rear side of the template 2 contacts the front side of the first side plate 3. The first adjusting screw 9 is rotated, which moves the second side plate 8 to the right, so that the rear side of the second side plate 8 contacts the front side of the template 2. Thus, the template 2, the second side plate 8, and the first side plate 3 surround the bottom, front, and rear of the casting groove 13, facilitating subsequent... The concrete is poured in stages. Then, the clamping mechanism 12 is used to connect the template 2 to the two composite slab bodies 1, so that the fixed clamping plate 12-2 contacts the bottom surface of the template 2. The second adjusting screw 12-5 is rotated, and the second adjusting screw 12-5 drives the movable clamping plate 12-4 to descend, so that the pad 12-7 contacts the top surface of the composite slab body 1, thereby connecting the composite slab body 1 and the template 2 together. Finally, the concrete is poured. The operation is convenient, avoids the leakage of grout during the concrete pouring process, and greatly improves the quality of concrete pouring.
