[0021] Example:

[0022] This application discloses a concrete formwork fixing device for building construction. Please refer to [link / reference]. Figs. 1 to 3The system includes a left horizontal column 1, a right horizontal column 2 on one side of the left horizontal column 1, a rectangular groove 3 on one side of the right horizontal column 2, a front horizontal column 4 slidably sleeved through the inner wall of the rectangular groove 3, one end of the front horizontal column 4 being fixedly connected to one side wall of the left horizontal column 1, a notch 5 embedded in the front side of the middle of the rectangular groove 3, grooves 6 distributed on one side of the notch 5, grooves 6 embedded in one side of the middle of the front end face of the front horizontal column 4, and multiple teeth 7 linearly and evenly formed on the side of the groove 6 facing away from the notch 5, a locking element 8 provided on the side of the right horizontal column 2 near the notch 5, and the left horizontal column 1 and right horizontal column 2... Each of the rear sides has a receiving groove 9. The center of the rear side of the left horizontal column 1 and the right horizontal column 2 is fixedly installed with screw 10 and screw 2 11 respectively through the receiving groove 9. The rear side of the left horizontal column 1 and the right horizontal column 2 are slidably sleeved with the rear horizontal column 12 through the receiving groove 9. One side of the rear horizontal column 12 has an insertion hole 13, and one side of the rear horizontal column 12 is movably inserted into the outer wall of screw 10 through the insertion hole 13. The other side of the rear horizontal column 12 has an adjustment slot 14, and the other side of the rear horizontal column 12 is movably inserted into the outer wall of screw 2 11 through the adjustment slot 14. Locking wheels 15 are distributed inside the receiving grooves 9 on both sides.

[0023] Two locking wheels 15 are screwed onto the outer walls of screw 10 and screw 2 11 respectively, and both locking wheels 15 are movably abutting against the side of the rear crossbar 12 away from the front crossbar 4. Multiple extension levers are uniformly fixedly connected to the outer walls of both locking wheels 15, and a rubber pad is fixedly installed on the outer surface of each extension lever. The multiple extension levers and rubber pads on the outer walls of the locking wheels 15 facilitate the rotation of the locking wheels 15 and also improve the contact effect with the hand. Multiple limiting cylinders 16 are linearly and uniformly fixedly connected to the middle position of the bottom of the left crossbar 1 and the right crossbar 2, and each limiting cylinder 16 is a circular cylindrical structure made of metal.

[0024] The locking component 8 includes a movable block 81 that is slidably sleeved at the junction of the notch 5 and the groove 6. The rear end face of the movable block 81 is linearly and uniformly fixedly connected with multiple locking teeth 82, which respectively engage with the inner wall of a portion of the tooth groove 7. A connecting rod 83 is fixedly connected at the center of the front end face of the movable block 81. The connecting rod 83 is slidably sleeved through the front end cavity of the right horizontal column 2, and a limiting piece 84 is fixedly connected to the front end of the connecting rod 83. A spring 85 is fixedly connected to the outer periphery of the rear end face of the limiting piece 84. The spring 85 is located on one side of the connecting rod 83, and the side of the spring 85 facing away from the limiting piece 84 is fixedly connected to the outer surface of the front end of the right horizontal column 2. The limiting piece 84 is located on the outer side of the front end of the right horizontal column 2, and a semi-circular annular metal pull ring is fixedly installed on the front end face of the limiting piece 84. The metal pull ring facilitates the lateral pulling operation of the limiting piece 84.

[0025] The implementation principle of this embodiment is as follows: During use, when the two locking wheels 15 disengage from the outer walls of screw 10 and screw 2 respectively, the rear horizontal column 12 is separated from the receiving groove 9 on the rear side of the left horizontal column 1 and right horizontal column 2. Then, based on the square structure assembled by the concrete formwork for the load-bearing columns of the building construction, after selecting the appropriate height for fixing, the left horizontal column 1 and right horizontal column 2 are supported on the ground by the support of multiple external round rod workpieces (this operation is to insert the top of each matching round rod workpiece into the inner wall of each limiting insert 16 while supporting the bottom of each round rod workpiece against the ground). The "U" shaped structure formed by the left horizontal column 1, right horizontal column 2, and front horizontal column 4 is fitted onto the outer surface of the concrete formwork. Then, the distance between the left horizontal column 1 and right horizontal column 2 is adjusted according to the specific width of the concrete formwork. The spacing is adjusted by simply pulling the limiting piece 84 with the metal pull ring, which causes the spring 85 to stretch and deform. At this time, the connecting rod 83 and the moving block 81 are adjusted laterally (during this process, the moving block 81 performs a limited sliding movement at the junction of the notch 5 and the groove 6). This indirectly causes each locking tooth block 82 to disengage from the locking engagement state of part of the tooth groove 7. Then, through the sliding sleeve action of the front horizontal column 4 and the rectangular groove 3 on one side of the right horizontal column 2, the spacing between the left horizontal column 1 and the right horizontal column 2 can be indirectly adjusted. After adjustment, the outer surfaces of the left horizontal column 1, the right horizontal column 2, and the front horizontal column 4 are all tightly attached to the outer surface of the concrete template. Through the reset action of the spring 85, multiple locking tooth blocks 82 are locked into the other part of the tooth groove 7 to achieve the locking state between the right horizontal column 2 and the front horizontal column 4.

[0026] Then, while simultaneously fitting the rear horizontal column 12 onto the inner walls of the two receiving grooves 9, it is fitted onto the outer wall of the screw rod 10 through the insertion hole 13 on one side of the rear horizontal column 12, and onto the outer wall of the screw rod 11 through the adjustment slot 14 on the other side of the rear horizontal column 12 (since the adjustment slot 14 is a long strip-shaped groove structure, it can adapt to different spacing positions of the left horizontal column 1 and the right horizontal column 2 and connect with the screw rod 11), until the rear horizontal column 12 is tightly fitted to the outer surface of the missing side of the concrete formwork. Then, by rotating and adjusting the screw positions of the screw rod 10 and the screw rod 11 through the two locking wheels 15, the abutment-type locking work of one side of the rear horizontal column 12 can be achieved. When dismantling later, simply unscrew and remove the two locking wheels 15, remove the rear horizontal column 12 away from the inner walls of the two receiving grooves 9, and then adjust and extend the left horizontal column 1 and the right horizontal column 2 to complete the overall dismantling operation on the outer surface of the concrete formwork.

[0027] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
