Description

Technical Field

[0001] This utility model belongs to the field of building engineering, and in particular relates to a reinforcement device for beam-column junction formwork. Background Technology

[0002] In cast-in-place concrete construction, the beam-column joint area presents a significant challenge due to its complex structure and the difficulty in reinforcing the formwork. This is especially true when beams are high, as the formwork at the joint becomes longer. Excessive lateral pressure on the formwork can easily cause bending or even breakage, leading to bulging, grout leakage, and other quality issues that severely impact construction quality and safety. Traditional reinforcement methods often employ timber supports or wire binding, which suffer from insufficient support strength, poor adaptability, low installation efficiency, and the inability to wrap around column stirrups. These methods also lack the ability to quickly and flexibly adjust to different beam widths and cantilever dimensions, and effective buckling prevention measures, failing to fundamentally solve the stability problem of cantilevered formwork. Therefore, a specialized formwork reinforcement device that can adapt to different sizes, is easy to install, and provides effective rigid support is urgently needed. Utility Model Content

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Unless otherwise specified, the technical means used in the embodiments are conventional means well known to those skilled in the art.

[0021] In the description of this utility model, it should be understood that the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0022] like Figure 1-2 As shown, the reinforcement device for the beam-column junction formwork includes a hinged seat 1, diagonal braces 2, reinforcing ribs 3, horizontal braces 4, and turnbuckle nuts 6. The two ends of the hinged seat 1 are symmetrically hinged to the diagonal braces 2, and the other ends of the two diagonal braces 2 are hinged to the horizontal braces 4. The ends of the two horizontal braces 4 that are close to each other are connected by the turnbuckle nuts 6. Several reinforcing ribs 3 are provided on the top of the horizontal braces 4, and the reinforcing ribs 3 are connected to the diagonal braces 2. The two diagonal braces 2 and the two horizontal braces 4 form a triangular structure. To accommodate formwork 7 of different sizes, the spacing between the two horizontal braces 4 can be adjusted by rotating the turnbuckle nuts 6 to compress a larger area of ​​the formwork 7 and to fasten the entire reinforcement device onto the formwork 7. After adjusting the spacing between the horizontal braces 4, the angle between the horizontal braces 4 and the diagonal braces 2 also changes. Therefore, the reinforcing ribs 3 need to be adjustable. The reinforcing ribs 3 connect the middle part of the horizontal braces 4 and the diagonal braces 2 to provide better torsional and deformation resistance, preventing the diagonal braces 2 from buckling (instability) under pressure. The entire reinforcement device is fastened to the template 7 to form a whole, increasing its rigidity and preventing breakage in the middle.

[0023] like Figure 2As shown, the reinforcing rib component 3 includes a base 305, with fixing screws 306 on both sides of the base 305; the top of the cross brace 4 has a sliding groove 402 along its length, and the two sides of the cross brace 4 have fixing grooves 401 communicating with the sliding groove 402 along their length; a plurality of the bases 305 are slidably disposed in the sliding groove 402, the fixing screws 306 are slidably engaged with the fixing grooves 401, and a clamping nut 307 is threadedly connected to the fixing screws 306. A clamping plate is provided on the inner side of the clamping nut 307, and the clamping plate has a large friction on both sides, which increases the friction between the clamping nut 307 and the cross brace 4, and better restricts the sliding of the base 305. When the clamping nut 307 is tightened, the sliding of the base 305 is restricted. The reinforcing rib component 3 also includes a rotating nut 303 and a reinforcing screw 301; the diagonal brace 2 has a plurality of through holes 201 arranged along its length; the top of the base 305 is provided with a threaded blind hole 304; the rotating nut 303 is hinged in the through hole 201; the reinforcing screw 301 is threadedly connected to the rotating nut 303 and the threaded blind hole 304. To adapt to the position of the rotating nut 303, the base 305 needs to be set to be horizontally adjustable. By adjusting the position of the base 305, it needs to be aligned with the rotating nut 303 on the same vertical line to facilitate the connection of the reinforcing screw 301. Since the angle of the rotating nut 303 will change accordingly after the angle of the diagonal brace 2 changes, the rotating nut 303 needs to be set to be rotatable so that it remains parallel to the cross brace 4 at all times so that the reinforcing screw 301 can be inserted into both the rotating nut 303 and the threaded blind hole 304 simultaneously to achieve the effect of a reinforcing rib.

[0024] Furthermore, the rotating nut 303 is symmetrically provided with two rotating rods 302 on both sides along the width direction of the diagonal brace 2. The rotating nut 303 is hinged in the through hole 201 through the rotating rods 302. The rotating nut 303 can only rotate in the plane where the horizontal brace 4 and the diagonal brace 2 are located.

[0025] More specifically, each of the two cross braces 4 is fixedly provided with a connecting screw 5 along its length on the side that is close to each other. The two connecting screws 5 are threadedly connected to the basket nut 6. When the basket nut 6 is rotated, it causes the two cross braces 4 to move away from or closer to each other.

[0026] In addition, a U-shaped groove 403 is fixedly provided at the bottom of the two cross braces 4 at their opposite ends, with the open ends of the two U-shaped grooves 403 facing each other; it also includes a template 7, with limiting protrusions 701 at both ends of the template 7 that are adapted to the U-shaped grooves 403, and the limiting protrusions 701 slidingly engaging with the U-shaped grooves 403. The U-shaped grooves 403 are fastened to both ends of the template 7, and by rotating the turnbuckle nut 6, the two cross braces 4 are brought closer together, thereby making them tightly fastened.

[0027] Workflow: Measure the length of template 7, rotate the adjusting turnbuckle nut 6 to make the two cross braces 4 reach the appropriate length (slightly longer than template 7), so that the two U-shaped slots 403 are located at both ends of template 7 respectively. Rotate the turnbuckle nut 6 to bring the two cross braces 4 closer together so that the U-shaped slots 403 are engaged with the limiting protrusions 701. Tighten the reinforcing screw 301 into the rotating nut. Adjust the position of the base 305 appropriately so that the threaded blind hole 304 is aligned with the reinforcing screw 301. Continue to tighten the reinforcing screw 301 to connect with the threaded blind hole 304. After it is in place, tighten the clamping nut 307 to restrict the movement of the base 305. Repeat the above steps for reinforcing screw 301 to ensure that each reinforcing screw 301 is in place.

[0028] The embodiments described above are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Any modifications, alterations, alterations, or substitutions made by those skilled in the art to the technical solutions of the present utility model without departing from the spirit of the present utility model shall fall within the protection scope defined by the claims of the present utility model.
