Description

Technical Field

[0001] The present application relates to the technical field of pre-embedded steel bar positioning, and in particular to a beam-support permanent-temporary combination used as a wall pre-embedded steel bar positioning constraint component. Background Art

[0002] The combination of permanent and temporary facilities is a construction method that aims to reduce repeated waste of materials through early planning and reasonable allocation and utilization of various resources. This method combines temporary facilities with permanent facilities in engineering construction for one construction, allowing some permanent facilities to be used during the construction process. The combination of permanent and temporary facilities has the advantages of improving material utilization and saving engineering costs.

[0003] During civil construction, it is sometimes necessary to make the top plate and top beam first, and then make the wall below. During the construction process, the steel bars need to be embedded in the top plate or top beam, and then peeled off from the concrete protective layer for connection after the earthwork is excavated in the later stage. However, since the joint position is embedded at the bottom of the beam and the top plate, it is impossible to observe whether the embedded steel bars are offset at any time during the pouring of the beam, resulting in the inability to correct the offset of the embedded steel bars in time, affecting the construction operation of the side wall in the later stage and reducing the construction efficiency.
