Detailed implementation manners

[0024] The following further elaborates on the present utility model in conjunction with the Figures 1-6 accompanying drawings.

[0025] An embodiment of the present utility model discloses a detachable bottom beam movable groove cleaning hole device. Referring to Figures 1-3 , it includes a main buckle 1 and a movable mechanism installed in the middle of the main buckle 1 for shielding and filling the groove cleaning hole at the bottom of the beam. The main buckle 1 is installed on the support system of the external beam bottom.

[0026] Referring to Figures 1-3 , the movable mechanism includes a first screw 2 arranged in the middle of the main buckle 1, a sleeve 21 threadedly arranged on the outer wall of the top end of the first screw 2, and a baffle 22 fixedly arranged at the top end of the sleeve 21 and adapted to the inside of the groove cleaning hole at the bottom of the beam. To facilitate disassembly and ensure the hardness of the baffle 22, the baffle 22 can be made of steel plate or aluminum alloy material, and at the same time, the thickness is not less than 4 mm, having a certain rigidity to ensure that it does not deform under the pressure of concrete pouring. The sleeve 21 is welded to the lower part of the baffle 22 to ensure the welding quality. At the same time, the height of the sleeve 21 needs to be greater than 4 cm to prevent falling off. The diameter of the sleeve 21 is selected according to the size of the first screw 2, generally not less than M14.

[0027] After people rotate the sleeve 21, it will drive the sleeve 21 outside the first screw rod 2 and the baffle 22 at the top to move up and down, so that the baffle 22 can enter the cleaning slot hole at the bottom of the beam, to seal and fill the cleaning slot hole. A seal can be set at the connection between the baffle 22 and the cleaning slot hole to avoid quality risks such as formwork swelling and slurry leakage at the bottom of the beam. The specification of the first screw rod 2 is matched with that of the sleeve 21, and the height should be 10-20 cm, ensuring that the first screw rod 2 is screwed into the sleeve 21 by at least 3 cm.

[0028] Refer to Figures 1-3 , a first connecting cylinder 23 is fixedly provided in the middle of the bottom surface of the main buckle 1. The bottom end of the first screw rod 2 is threadedly arranged in the first connecting cylinder 23. After the baffle 22 moves up and down into the corresponding cleaning slot hole at the bottom of the beam, people can rotate the first screw rod 2 in the first connecting cylinder 23 to continuously lift and lower the baffle 22, so that the baffle 22 can reach the indicated position. The height of the sleeve 21 is lower than the thickness of the secondary keel of the external beam bottom support system, ensuring that the first screw rod 2 can smoothly adjust the height of the baffle 22, so that the upper surface of the baffle 22 can fit the upper opening of the beam formwork.

[0029] Refer to Figure 2 and Figure 4 , secondary buckles for ensuring the firmness after the device is installed are provided on both sides of the main buckle 1. The secondary buckle includes a first L-shaped plate 3 and a second L-shaped plate 31 stacked relative to each other. Tooth grooves 32 are provided in both the first L-shaped plate 3 and the second L-shaped plate 31, and the bottom of the secondary buckle is in abutting connection with the top of the main buckle 1.

[0030] Refer to Figures 4-6 , second connecting cylinders 4 are fixedly provided on both sides of the bottom of the main buckle 1. A driving mechanism for driving the first L-shaped plate 3 and the second L-shaped plate 31 to move relative to each other to change the internal dimension of the secondary buckle and fix the secondary buckle to the secondary keel at the bottom of the beam is provided in the main buckle 1. The driving mechanism includes a second screw rod 41 rotatably arranged in the second connecting cylinder 4, and gears 42 fixedly provided on the outer wall of the top end of the second screw rod 41 and meshingly connected to the tooth grooves 32 in the first L-shaped plate 3 and the second L-shaped plate 31 respectively. To ensure firmness after installation, one movable secondary buckle is added to each side part of the main buckle 1. The secondary buckle is formed by stacking the first L-shaped plate 3 and the second L-shaped plate 31 made of steel plate or aluminum alloy plate relative to each other, and the overlapping part uses the gear 42 as the transmission.

[0031] People can drive the two gears 42 at the top to rotate by rotating the second screw rod 41. With the connection of the tooth grooves 32, the relative first L-shaped plate 3 and the second L-shaped plate 31 are driven to move horizontally closer to or away from each other, so as to change the internal dimension of the secondary buckle, facilitating people to fix the secondary buckle to the secondary keels with different dimensions in the beam bottom support system to ensure firmness after installation.

[0032] Refer to Figures 4-6, a connecting ring 43 is fixedly arranged on the outer wall of the second screw rod 41. The connecting ring 43 is rotatably connected in the second connecting cylinder 4. The connecting ring 43 can connect the second screw rod 41 and the second connecting cylinder 4, so that the second screw rod 41 can rotate in the second connecting cylinder 4 without falling off.

[0033] Refer to Figures 4-6 , a plum blossom-shaped hand-tightening screw 44 for people to rotate is fixedly arranged at the bottom end of the second screw rod 41, and a head 45 is fixedly arranged at the top end of the second screw rod 41 to cooperate with and abut against the top of the secondary buckle. People can drive components such as the second screw rod 41 to rotate through the plum blossom-shaped hand-tightening screw 44. The head 45 can cooperate with the main buckle 1 to limit the first L-shaped plate 3 and the second L-shaped plate 31, and ensure that the gear 42 does not fall off. The head 45 can be a steel plate. By rotating the plum blossom-shaped hand-tightening screw 44, the reduction and enlargement of the internal dimension of the secondary buckle can be controlled, so that it can be fastened on the secondary keel of the support system, so as to ensure firmness after installation. The secondary keel of the support system at the bottom of the external beam can adopt wooden square timbers, square steel pipes, etc., and ensure that the maximum internal width of the secondary buckle is greater than the width of the secondary keel, which is convenient for adjustment and reinforcement.

[0034] The implementation principle of a detachable bottom beam movable groove cleaning hole device in an embodiment of the present invention is as follows:

[0035] After formwork support at the bottom of the beam, according to the position of the secondary keel of the beam bottom support system and the part to be cleaned, reserve the position of the groove cleaning hole, and the opening can be the same size as the device baffle 22 by an electric saw;

[0036] After groove cleaning is completed, first install the main buckle on the beam bottom support system, and then adjust the plum blossom-shaped hand-tightening screw 44 on the secondary buckle to drive the second screw rod 41 to rotate, thereby driving the two gears 42 at the top to rotate. With the connection of the tooth grooves 32, the opposite first L-shaped plate 3 and the second L-shaped plate 31 are driven to move horizontally closer to or away from each other, so as to change the internal dimension of the secondary buckle, which is convenient for people to fix the secondary buckle to the secondary keels of different sizes in the beam bottom support system to ensure firmness after installation.

[0037] Then, by rotating the sleeve 21 or the first screw rod 2, drive the baffle 22 to move up and down, so that the upper surface of the baffle 22 is flush with the upper surface of the beam formwork, so as to fill and seal the groove cleaning hole at the bottom of the beam;

[0038] After the concrete in the bottom of the beam is poured, the device can be removed by loosening the plum blossom-shaped hand-tightening screw 44 of the secondary buckle, achieving the effect of reusable.
