Replacement construction method for post-adding reinforced concrete beam unit for wall

Abstract

A construction method of wall body post-reinforced concrete beam element displacement relates to the technical field of wall construction, specifically comprising: step 1, manufacturing a support unit; step 2, drawing contour lines of an opening (1), a lintel (3) and a support tunnel (2); step 3, chiseling the support tunnel (2) one by one and placing the support unit; step 4, sheathing stirrup and penetrating main reinforcement; step 5, supporting formwork and pouring concrete; step 6, dismounting formwork, cleaning edge and maintaining; step 7, excavating holes. In the construction method of the invention, the processes of element displacement and one-time pouring are adopted, thus solving the potential safety hazard that one-time excavation of too large holes during lintel displacement can easily cause wall body collapse, ensuring that the lintel displacement is free from the limit of the opening width and being applicable to openings of various width and shapes.

Description

technical field [0001] The invention relates to the technical field of wall reconstruction, in particular to a construction method for replacing a reinforced concrete beam unit after a wall. Background technique [0002] In the renovation of existing projects, opening holes in existing walls is a relatively common phenomenon. For openings with larger widths, lintels need to be set. At present, there are two common methods for setting the lintel, one is to open the hole first and then add the lintel, and the other is to add the lintel first and then open the hole. The first method has great potential safety hazards for the larger openings, and the second method is mainly to add angle steel or channel steel in the mortar joints of the wall, and then open the hole. Because in the process of adding angle steel or channel steel, it is necessary to remove the gray joints half of the thickness of the wall, so there are certain potential safety hazards.

Problems solved by technology

[0003] Aiming at the defects existing in the prior art, the object of the present invention is to provide a construction method for unit replacement of reinforced concrete beams after the wall, which adopts the technology of unit replacement and one-time pouring, and solves the problem of excessive opening in the process of lintel replacement. It is easy to cause the safety hazard of wall collapse, so that the replacement of the lintel is not limited by the width of the opening, and is suitable for openings of various widths and shapes
