Technical Field

[0001] The utility model relates to a concrete formwork clamp, in particular to a frame beam formwork reinforcement device, and belongs to the technical field of frame beam concrete construction. Background Art

[0002] With the continuous development of the construction field, the use of concrete structure engineering for the main body of tall buildings is becoming more and more popular. The concrete structure frame beam is the main load-bearing part of the building. The frame structure has superior characteristics in large space, large span, earthquake resistance, standardization, etc. The ultra-high and large-span concrete structure indoor substation is constructed with high-grade concrete. The foundation is a reinforced concrete raft foundation. The frame columns are rooted in the foundation steel bars. The two ends of the frame beam are anchored in the frame columns, and the frame columns serve as supports. Due to the large span and high height of the frame beam, the template reinforcement needs to punch holes to reinforce the wire rods, but it takes a long time and effort. There are through-wall holes in the beam reinforcement, and the through-wall sleeves need to be pre-buried in the inner wall of the hole. After the mold is removed, the sealing of the wire drawing holes is cumbersome and consumes a lot of manpower and material resources. Utility Model Content

[0017] The utility model is further explained and illustrated below in conjunction with the accompanying drawings:

[0018] Example, see Figure 1-Figure 2 A frame beam formwork reinforcement device includes a square steel sleeve 1, a displacement square steel 2 and a screw 4. There are two square steel sleeves 1, and a top support 7 is arranged on the inner wall of each square steel sleeve 1, and an adjustable screw 9 is connected between the two top supports 7 by threads, and a tensioning screw 4 is arranged above the adjustable screw 9. The tensioning screw 4 passes through the two square steel sleeves 1, and a mountain-shaped clip 5 and a nut 6 are arranged on the screw 4 outside the square steel sleeve 1, a displacement square steel 2 is inserted at the top of the square steel sleeve 1, and a clamp 3 is arranged on the inner wall of the displacement square steel 2.

[0019] The displacement square steel 2 is fixedly connected to the square steel sleeve 1 by bolts, and the clamp 3 is fixedly connected to the displacement square steel 2 by bolts.

[0020] There is at least one clamping member 3 which is distributed in a U-shape, and the thickness of the clamping member 3 is consistent with the wall thickness of the square steel sleeve 1 .

[0021] The mountain-shaped clamp 5 is sleeved on the tensioning screw 4 outside the square steel sleeve 1 and is clamped and fixed by a nut 6.

[0022] The top support 7 is distributed in a U-shape, and a threaded barrel 8 is arranged in the middle of the outer wall of the top support 7. External threads are arranged at both ends of the adjustable screw 9, which are connected to the corresponding threaded barrel 8 through threads respectively, and the external threads at both ends of the adjustable screw 9 are distributed in opposite directions.

[0023] The jacking support 7 is located at the middle and lower part of the square steel sleeve 1 .

[0024] In the above description, the size of the top support matches the size of the square steel sleeve, and the size of the clamp matches the size of the displacement square steel.

[0025] In the above description, by rotating the adjustable screw rod, the distance between the two support brackets can be expanded or reduced at the same time.

[0026] In the above description, the displacement square steel can move up and down along the square steel sleeve and is fixed by bolts on the outer wall of the square steel sleeve.

[0027] In the above description, the clips are connected to the displacement square steel through threads, and the number of clips depends on the number of wooden strips B. That is to say, where there are wooden strips, clips need to be installed between the wooden strips and the displacement square steel to avoid gaps between the displacement square steel and the wooden strips and ensure the overall firmness.

[0028] In the above description, during construction, at least 2 sets of the device are used, depending on the length of the specific frame beam.

[0029] Working principle:

[0030] Before use, position and lay out on the cushion layer (floor) according to the requirements of the drawings, and insert the displaced square steel into the square steel sleeve so that it can be checked and adjusted according to the height of the beam body, and finally fixed with bolts on the outside of the square steel sleeve; by passing the tensioning screw between the two square steel sleeves under the formwork, it not only supports the formwork, but also tightens the formwork; by installing the top support and adjustable screw under the tensioning screw, the expansion and external support at the bottom of the square steel sleeve can be avoided. Because the formwork is under stress in an outward tension state when the beam body is cast, holes are punched in the square steel sleeve to pass the wire rod to achieve a tensioning state. However, because the tension at the lowest end of the square steel sleeve is too large, the square steel is stressed into an inverted "eight" shape. Therefore, an adjustable inner support is placed on the inner side of the lowest end of the square steel sleeve to expand outward.

[0031] The side formwork can be removed only after the pouring of the beam is completed to ensure that the edges and corners of the components are not damaged. First, remove the inner support, then loosen the tension rods, and move the reinforcement parts out of the formwork and stack them to facilitate material recycling and reuse.

[0032] The utility model is used for the reinforcement of frame beam formwork. Since the reinforcement workload of the beam body is large, the process is too complicated, the engineering consumables are large, the concrete appearance quality requirements are high, and the structural size deviation is small, this tool can ensure the concrete molding quality, the molding error is small, and it is convenient, fast, efficient, and material-saving, and is very suitable for fixing the frame beam formwork.

[0033] The above is only the preferred implementation of this patent. It should be pointed out that for those skilled in the art, several changes and improvements can be made without departing from the overall concept of this patent, and these should also be regarded as the scope of protection of this patent.
