Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a column template fixing structure. Background Art

[0002] For cast-in-place columns, support column formwork is required during construction. For super-high cast-in-place columns, since the bottom of the column formwork is subjected to greater force during pouring, higher requirements are placed on the strength and stability of the fixed structure of the super-high column formwork.

[0003] The column formwork fixing structure currently used includes four metal clamps, one end of the clamp is bent to form a U-shaped hanging part, and the other end is provided with a strip hole. The clamps are interlocked and connected with each other through the U-shaped hanging part, and then a triangular fixing plate is inserted into the strip hole, and the fixing plate is squeezed into the strip hole by hammering. At the same time, one side of the fixing plate is against the hanging part of the clamp, so as to push the hanging part to drive the clamp to move, and then squeeze the column formwork to achieve the fixation of the column formwork. However, the existing fixing plate is an isosceles triangle structure, and the strip hole is a through hole with a straight hole wall. The fixing plate relies on its own deformation under the action of hammering to fit into the strip hole, and it is not in surface contact with the hole wall of the strip hole. Moreover, the shape of the fixing plate determines that one side of it is not in surface contact with the hanging part, but in point contact. The contact point relies on a certain concave deformation under the action of force to increase the friction or bite force, thereby achieving the fixation of the fixing plate and blocking the movement of the clamp. Therefore, since such a fixed structure is in point contact and the two contact points are not in the same straight line, during the pouring process, the reaction force of the column formwork can easily cause the fixed plate to rotate at a certain angle, causing it to loosen or even fall off, causing it to lose its fixed limit function and have poor stability. At the same time, the fixed plate and the hanging part are only in contact at one point, so that the upper and lower forces of the hanging part are uneven. When the fixed plate pushes the hanging part to move, it is easy for the hanging part to deflect and get stuck, affecting the adjustment of the splint and causing inconvenience to the fixation of the column formwork. Furthermore, the existing fixed plate relies on deformation to increase friction. As the number of uses increases, the fixed plate deforms severely and is difficult to reuse, resulting in a waste of resources and high maintenance costs. Summary of the invention

[0004] In view of the above-mentioned deficiencies of the prior art, the technical problem to be solved by the utility model is: to provide a column template fixing structure, which solves the problems of poor stability, unreliable fixation and difficulty in reuse of the existing splint fixing structure.

[0005] In order to solve the above technical problems, the utility model adopts the following technical solutions:

Correspondingly, a plurality of second pin holes through which the pin can pass are opened on the fixing plate. When the fixing plate moves, the first pin hole can be opposite to one of the plurality of second pin holes.

[0008] As an optimization, the plurality of second pin holes are distributed in a straight line along a direction parallel to the hypotenuse of the fixing plate.

[0009] As an optimization, the second pin holes include two parallel rows, and the second pin holes in the two rows are staggered.

[0012] Compared with the prior art, this application has the following beneficial effects:

[0013] The present application adopts a right-angled triangle fixing plate, and sets a slope matching the fixing plate on the hole wall of the fixing hole, so that the fixing plate is in surface contact with the hanging part and the fixing hole. In this way, the pushing effect of the fixing plate on the hanging part is more uniform, preventing the hanging part from getting stuck and affecting its adjustment. At the same time, the surface contact reduces the deformation of the fixing plate, increases its use times, and the larger contact area can also provide a more stable friction force, which has a better fixing effect.

[0019] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0020] For specific implementation: see Figure 1-4 A column template fixing structure comprises a first clamping plate 1 and a second clamping plate 2 of the same structure, wherein a plurality of first clamping plates 1 and second clamping plates 2 are vertically cross-connected and enclosed on the outside of the column template to fix the column template; wherein one end of the first clamping plate 1 is bent and extended to form a U-shaped hanging portion 3, and a plurality of strip-shaped fixing holes 4 extending along the thickness direction thereof are opened on the plate surface near the other end, the hanging portion 3 of the first clamping plate 1 is sleeved on the second clamping plate 2 through its U-shaped groove, and a triangular fixing hole 4 is inserted into the fixing hole 4 of the second clamping plate 2 The fixing plate 5 is shaped like a right triangle, one side of which is against the hanging part 3 of the first clamping plate 1, so as to realize the connection and fixation between the first clamping plate 1 and the second clamping plate 2; the fixing plate 5 is a right triangle structure, one of which is against the hanging part 3 of the first clamping plate 1, and the other is in a horizontal state, and its hypotenuse is located on the side of the fixing plate 5 away from the first clamping plate 1, and correspondingly, the hole wall of the fixing hole 4 of the second clamping plate 2 facing the hypotenuse of the fixing plate 5 is provided with a slope 6 with the same slope, and the hypotenuse of the fixing plate 5 is in contact with the slope 6. In this way, the reaction force of the column formwork is mainly resisted by the friction between the slope 6 and the hypotenuse of the fixing plate 5, and the direction of the friction is parallel to the slope 6. Even if the reaction force is large, the fixing plate 5 is squeezed out of the fixing hole 4, and no corner is generated to cause a large deformation of the fixing plate 5, which affects its use.

[0021] Therefore, in order to further improve the fixing effect, a first pin hole 7 extending along the width direction of the second clamping plate 2 is provided on the side surface thereof, the first pin hole 7 is communicated with the fixing hole 4, and a pin 8 is passed through the first pin hole 7. Correspondingly, a plurality of second pin holes 9 through which the pin 8 can pass are provided on the fixing plate 5. When the fixing plate 5 moves, the first pin hole 7 can be directly opposite to one of the plurality of second pin holes 9. When in use, after the fixing plate 5 is moved to a suitable position, the pin 8 is passed through to completely fix it. The pin 8 cooperates with the friction force to greatly improve its fixing effect, further preventing the fixing plate 5 from being separated from the fixing hole 4 under the reaction force, thereby improving its safety in use.

[0022] In order to improve its flexibility, in this embodiment, a plurality of second pin holes 9 are linearly distributed along a direction parallel to the hypotenuse of the fixed plate 5. The second pin holes 9 include two parallel rows, and the two rows of second pin holes 9 are staggered. The first pin hole 7 is a strip hole extending along the length direction of the second clamping plate 2. In this way, the position of the pin 8 can be moved left and right for adjustment, so as to better and more quickly align the second pin hole 9, and the distribution of the second pin holes 9 is distributed along the moving direction of the fixed plate 5, so that the second pin holes 9 are basically maintained within the strip range of the first pin holes 7 when the fixed plate 5 moves, and the second pin holes 9 include two staggered rows, so that the fixed plate 5 can insert the pin 8 into the second pin hole 9 when it moves to any position, thereby improving its continuity of adjustment and making it more flexible and convenient to use.

[0023] The plurality of fixing holes 4 are linearly distributed along the length direction of the first clamping plate 1, and include two rows, and the two rows of fixing holes 4 are staggered. This arrangement is also to ensure that the fixing plate 5 can be inserted into the fixing holes 4 at as many positions as possible to limit and fix the clamping plate, thereby improving the continuity and flexibility of its adjustment.

[0024] The present application adopts a right-angled triangle fixing plate, and sets a slope matching the fixing plate on the hole wall of the fixing hole, so that the fixing plate is in surface contact with the hanging part and the fixing hole. In this way, the pushing effect of the fixing plate on the hanging part is more uniform, preventing the hanging part from getting stuck and affecting its adjustment. At the same time, the surface contact reduces the deformation of the fixing plate, increases its use times, and the larger contact area can also provide a more stable friction force, which has a better fixing effect. The fixing plate is not easy to rotate under the reaction force, and has better stability.
