Specific embodiments

[0022] Next, with reference to the accompanying drawings, the specific embodiments of the present utility model will be described in detail, but it should be understood that the protection scope of the present utility model is not limited by the specific embodiments.

[0023] Unless otherwise clearly stated, throughout the specification and claims, the term "comprising" or its variations such as "including" or "having" etc. will be understood to include the stated elements or components, without excluding other elements or other components.

[0024] The present utility model provides a reinforcement structure for an assembled beam, which is provided with reinforcement support members with adjustable height and spacing, and is applicable to the reinforcement of beams with different heights and widths. It is simple to use, and a bottom support for providing support to the bottom of the assembled beam makes the in - situ beam reinforcement stable and firm. A support rod is arranged on the side of the reinforcement support member, and the sliding mechanism connected to the top of the support rod can be locked to solve the construction problems of precast beam installation positioning and anti - tipping. Compared with the prior art, the use of traditional tools such as screw rods and step - by - step fasteners for beam - side reinforcement has better forming quality.

[0025] Embodiment 1:

[0026] A reinforcement structure for an assembled beam, as Figures 1 to 3 shown, environment: The reinforcement structure of the assembled beam is installed on the erected formwork support system and is connected to the formwork uprights on both sides of the beam by traditional fasteners. The reinforcement structure of the assembled beam is installed at the bottom and on both sides of the precast beam, and is used for reinforcing the beam side and providing support. It includes: a bottom support 1, and a pair of reinforcement support members 2. The reinforcement support member 2 includes a height adjustment mechanism 21 and a sliding mechanism 22. The sliding mechanism 22 is located at the bottom of the reinforcement support member 2. The sliding mechanism 22 and the bottom support 1 are movably connected, and the sliding mechanism 22 can slide and be locked on the bottom support 1.

[0027] Specifically, the base support 1 is used to carry the precast beam and install the reinforcement support 2. The height of the reinforcement support 2 can be adjusted by the height adjustment mechanism 21. The two reinforcement supports 2 can slide freely on the base support 1 through the sliding mechanism 22 and are fixed in position by locking the sliding mechanism 22 to adjust the spacing between the reinforcement supports 2. By adjusting the height and spacing of the reinforcement supports 2, precast beams of different specifications can be accommodated.

[0028] As an alternative embodiment, the height adjustment mechanism 21 includes an inner tube 211, a sleeve 212, and a fixing pin 213. The sleeve 212 is located outside the inner tube 211. The inner diameter of the sleeve 212 matches the outer diameter of the inner tube 211. A plurality of first through holes 214 are longitudinally provided on the inner tube 211, and a plurality of second through holes 215 are longitudinally provided on the sleeve 212. By matching different first through holes 214 and different second through holes 215 on the inner tube 211 and the sleeve 212, the height of the reinforcement support 2 can be adjusted. The fixing pin 213 is used to penetrate the matched first through hole 214 and second through hole 215 to lock the height of the reinforcement support 2.

[0029] Specifically, since the sleeve 212 has a larger bottom area and greater mass, the structure with the sleeve 212 located below and the inner tube 211 located above can lower the center of gravity of the height adjustment mechanism 21 and make the height adjustment mechanism 21 more firmly supported. As a preferred embodiment, the punching direction of the sleeve 212 is from top to bottom, and the punching direction of the inner tube 211 is from bottom to top.

[0030] As an alternative embodiment, the reinforcement support 2 further includes a support rod 23. The bottom end of the support rod 23 is connected to the sliding mechanism 22, and the support rod 23 is disposed on the side opposite to the adjacent reinforcement support 2.

[0031] Specifically, the support rod 23 is located on the side of the height adjustment mechanism 21 and is used to reinforce the height adjustment mechanism 21 to prevent it from tipping over. As a preferred embodiment, the sliding mechanism 22 includes two parts, one part is connected to the bottom of the support rod 23, and the other part is connected to the bottom of the height adjustment mechanism 21.

[0032] As an alternative embodiment, the base support 1 is a straight tube arranged horizontally, the sliding mechanism 22 is arranged outside the base support 1, and the inner diameter of the sliding mechanism 22 matches the outer diameter of the base support 1.

[0033] Specifically, the sliding mechanism 22 is a sleeve 212 sleeved outside the straight pipe. The sliding adjustment mechanism can slide freely on the base 1 to change its position.

[0034] As an alternative embodiment, a third through hole 11 is provided on the base 1, and a fourth through hole 221 is provided on the sliding mechanism 22. The third through hole 11 and the fourth through hole 221 are locked by a positioning pin 12.

[0035] Specifically, the fourth through hole 221 is provided on one side close to the support rod 23. After locking, the reinforcement support member 2 cannot slide on the base 1 and is prevented from rotating.

[0036] As an alternative embodiment, the positioning pin 12 longitudinally penetrates the straight pipe.

[0037] Specifically, both ends of the positioning pin 12 are locked by the straight pipe. Compared with the situation where only one end is limited by the through hole and the other end is loose and can move freely, the reinforcement support member 2 can be locked more firmly and is not easily loosened.

[0038] As an alternative embodiment, there are multiple third through holes 11, which are symmetrically arranged at both ends of the base 1.

[0039] Specifically, the distance between a pair of the reinforcement support members 2 can be adjusted by the matching between different third through holes 11 and fourth through holes 221 and the locking of the positioning pin 12. The third through holes 11 are symmetrically arranged and are provided at both ends of the base 1, making the bearing capacities of the left and right ends of the base 1 more balanced after the precast beam is placed.

[0040] As an alternative embodiment, the included angle between the support rod 23 and the base 1 is greater than 45°.

[0041] Specifically, the distance between the sliding mechanism 22 connected to the bottom of the support rod 23 and the base 1 connected to the bottom of the height adjustment mechanism 21 is less than the height of the height adjustment mechanism 21. If the included angle between the support rod 23 and the base 1 is too small, that is, the distance between the sliding mechanism 22 at the bottom of the support rod 23 and the height adjustment mechanism 21 is too far, the locking effect of the positioning pin 12 is limited, which easily causes the height adjustment mechanism 21 to shake.

[0042] As an alternative embodiment, the spacing between the multiple first through holes 214 is different from the spacing between the multiple second through holes 215.

[0043] Specifically, the spacing between the multiple first through holes 214 is equal, the spacing between the multiple second through holes 215 is equal, and the spacing between the first through holes 214 is not equal to the spacing between the second through holes 215. Through the cooperation between different first through holes 214 and different second through holes 215, the adjustable range of the height adjustment mechanism 21 can be made wider, and the minimum adjustment limit can be reduced.

[0044] As an alternative implementation, the fourth through hole 221 is provided on the side of the sliding mechanism 22 close to the support rod 23.

[0045] Specifically, the fourth through hole 221 is provided on the outer side, that is, on the side close to the support rod 23, and the third through hole 11 is provided at positions close to both ends of the bottom support 1. Since the third through hole 11 is provided at both ends, the punching section does not directly bear the precast beam, and the influence of punching holes in the bottom support 1 on the bearing capacity and stability is relatively small.
