Structural beam formwork reinforcing device and method without split bolts

Abstract

The invention discloses a structural beam formwork reinforcing device and method without split bolts, and relates to the technical field of building construction. The device comprises a cross rod, a fixed vertical rod structure, an adjustable vertical rod structure and a fastening device. The fixed vertical rod structure and the adjustable vertical rod structure are arranged on the cross rod and arranged at the two ends of the cross rod correspondingly. A locking structure is arranged between the adjustable vertical rod structure and the cross rod. The fastening device is arranged on the otherside, relative to the fixed vertical rod structure, of the adjustable vertical rod structure, one end of the fastening device is movably connected with the cross rod, and the other end of the fastening device is movably connected with the adjustable vertical rod structure and used for supporting the adjustable vertical rod structure. By means of the technical scheme, the reinforcing effect of a structural beam formwork can be guaranteed, through-wall bolt holes can be effectively prevented from being left in a structural beam, and the construction quality of the structural beam is guaranteed;and multi-time circulation turnover use can be achieved, the construction cost is reduced, the characteristic of environmental friendliness is achieved, and the device and method have good application prospects and practical value in practice and are suitable for being used and popularized.

Description

technical field [0001] The invention relates to the technical field of building construction, and more specifically relates to a structural beam formwork reinforcement device and method without cross-tensioning bolts. Background technique [0002] In the construction process of existing buildings, when the traditional beam structure formwork is strengthened, the beam structure is usually strengthened by step-by-step clamps or pull bolts. However, in the actual construction process, the inventor of the present application found that there are at least the following technical problems in the use of step-by-step tightening fixtures or pull bolts to strengthen structural beams: the above-mentioned reinforcement method is not firm, and it is easy to bounce back, and it will be affected by vibration during the pouring process. The force from the tamping construction can easily lead to the failure of the step-by-step reinforcement; the reinforcement effect of using the pull bolt is...

However, in the actual construction process, the inventor of the present application found that there are at least the following technical problems in the use of step-by-step tightening fixtures or pull bolts to strengthen structural beams: the above-mentioned reinforcement method is not firm, and it is easy to bounce back, and it will be affected by vibration during the pouring process. The force from the tamping construction can easily lead to the failure of the step-by-step reinforcement; the reinforcement effect of using the pull bolt is better than that of the step-by-step clamp, but the use of the pull bolt to strengthen the beam structure will cause more beams to pass through the wall Bolt holes, especially on the connecting beams or balcony cantilever beams on the external wall, the bolt holes through the wall left after the structural beam formwork is demolished are very likely to cause leakage risks
