Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of building engineering, specifically, it is a beam bar position adjusting tool. BACKGROUND

[0002] The importance of the thickness control of the protective layer of reinforced concrete components is self-evident, and the relevant national standards also make strict provisions for the thickness of the protective layer under various environments. If the protective layer is too thin, on the one hand, it is easy to cause exposed reinforcement or surface concrete spalling when the reinforcement is stressed; on the other hand, as the surface concrete gradually carbonizes, the reinforcement is eroded prematurely, the cross-sectional area is reduced, the strength is reduced, the wrapping effect with the concrete is reduced, the integrity is destroyed, and a large structural safety hazard is caused.

[0003] In reinforced concrete components, due to the cross-sectional characteristics of beam components (narrow and high, small operation space, and large reinforcement ratio), the lower protective layer is too thin (or the cushion block is not placed in place) and the beam bar position is deviated (i.e. the protective layer spacing on the side of the beam is uneven) when the beam reinforcement is installed. A large area of exposed reinforcement at the bottom of the beam is caused by the failure to control the thickness of the protective layer (or even the absence of a protective layer). Therefore, before pouring the concrete, the beam bar position (i.e. the thickness of the protective layer) must be adjusted to meet the requirements of the design drawings and the standards.

[0004] In reinforced concrete cast-in-place structures, the beam reinforcement is placed in the beam formwork after being tied and bound, but the position of the beam reinforcement on the beam reinforcement skeleton is not suitable (the protective layer is too large or too small), and the position of the beam reinforcement needs to be adjusted. When the beam cross-section is large or the reinforcement ratio is high, such as the basement raft slab beam and the roof beam, the overall beam reinforcement is heavy, and it is not easy to adjust the position of the beam reinforcement with an ordinary crowbar, which can also damage the formwork (resulting in rework) and cannot be directly lifted by a tower crane (one of the prohibited behaviors of "ten not to lift", i.e. unclear lifting heavy load), so it is difficult to adjust.

[0005] Therefore, the known method of adjusting the position of the beam reinforcement with an ordinary crowbar has the above-mentioned inconveniences and problems. CONTENT OF THE UTILITY MODEL

[0006] The purpose of the utility model is to provide a safe and reliable beam bar position adjusting tool.

[0007] To achieve the above-mentioned purpose, the technical solution of the utility model is as follows:
