Problems solved by technology

However, under the working condition of relatively large new load, if the cross-sectional size of the original planar structural beam does not meet the requirements, it is necessary to take measures to increase the cross-section of the structural beam. The enlarged cross-section of the member will cause wet concrete work, so the cross-section must be enlarged Partial support formwork and bracket formwork system, especially in the case of relatively high building height, the support system requirements are more stringent, in some cases limited by site conditions, support formwork cannot be used, and it is uneconomical, especially wooden support After the template is reused 2-3 times, its strength will be greatly reduced and it will be scrapped immediately

Abstract

The invention relates to the technical field of building beam reinforcement, in particular to a beam reinforcement suspended formwork device and a construction method thereof. The beam reinforcement suspended formwork device comprises a beam body, a suspender assembly connected with the beam body, and a combined formwork arranged between the beam body and the suspender assembly; the combined formwork abuts against the suspender assembly; a reinforcing space used for containing reinforcing slurry is formed between the beam body and the combined formwork; the suspender assembly comprises a firststeel arm, a bearing part, and a second steel arm; one end of the first steel arm and one end of the second steel arm are connected with the two side faces of the beam body respectively; and the other end of the first steel arm and the other end of the second steel arm are movably connected with the two ends of the bearing part respectively. According to the beam reinforcement suspended formworkdevice, formwork erecting can be conducted without a support formwork erecting system, and a traditional wood support supporting system is replaced, so that the construction operation space is reduced, and the suspender assembly can be repeatedly used.

Description

technical field [0001] The invention relates to the technical field of building beam reinforcement, in particular to a beam reinforcement hanging formwork device and a construction method thereof. Background technique [0002] According to the continuous development of society, in order to meet the needs of production or life, it has become a common phenomenon to change the original functions of existing civil and industrial buildings, especially for the reasons of industrial plant floor equipment going upstairs and civil public building internal expansion space. Renovate the building to meet the new use requirements and carry out structural reinforcement. In the case of relatively small new loads, planar structural beams can meet the bearing capacity requirements by using carbon fiber or steel-bonded reinforcement technology. However, under the working condition of relatively large new load, if the cross-sectional size of the original planar structural beam does not meet t...
