Advanced construction method for masonry wall anchoring reinforcement

Abstract

The invention relates to an advanced construction method for masonry a wall anchoring reinforcement, which comprises the following steps of: binding a structural column or wall body steel bars, carrying out measuring, positioning and setting out for the wall anchoring reinforcement, constructing the wall anchoring reinforcement, placing a reinforced protective layer cushion block, inspecting before sealing the framework, sealing the formworks of the structural column or the wall body, pouring the structural column or the wall with concrete, curing and removing the formworks, correcting the wall anchoring reinforcement of the structural column or the wall body with exposed reinforcements, enclosing the tail end to a bending hook of 180 degrees, and carrying out the normal masonry construction of a secondary structure according to the requirements of the drawings. According to the invention, the procedures of secondary drilling, cleaning, reinforcement erecting and the like are not needed, the wall anchoring reinforcement is constructed in one take, the period is short, the drilling noise and dust pollution are reduced, the method is environmental protection, direct pre-embedded anchoring effect is obvious, particularly, the tensile strength is greatly increased after the hook is arranged at the tail end of the anchoring reinforcement, the bent anchoring reinforcements are tightly attached to the formwork, and the effect of an anchoring reinforcement protective layer is provided, the reservation of the inserting reinforcement is not needed, the formwork is not damaged, and the disassembling of the formwork is not difficult, the material cost of the rib planting glue and even the cost of the anti-drawing tests of the anchoring reinforcements are saved, and the cost is saved.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to an advance construction method for masonry tension wall reinforcement. Background technique [0002] The masonry structure is a secondary structure in a frame structure building, and generally does not bear loads. However, due to the seismic requirements of the building, there is a process before the masonry is that the concrete columns (or walls) need to be in accordance with the requirements of the drawings or specifications. Set the wall tie bars at a certain distance (generally 500-600mm). The wall tie bars are generally two Φ6 (or Φ8) diameter steel bars that are buried by drilling and planting bars. The general drilling depth is 100mm (or 10d), but In this method, there are a series of processes that require drilling, cleaning, plastering, glueing, and test drawing. Any process will cause certain quality defects regardless of the quality of the raw materials, ...

[0002] The masonry structure is a secondary structure in a frame structure building, and generally does not bear loads. However, due to the seismic requirements of the building, there is a process before the masonry is that the concrete columns (or walls) need to be in accordance with the requirements of the drawings or specifications. Set the wall tie bars at a certain distance (generally 500-600mm). The wall tie bars are generally two Φ6 (or Φ8) diameter steel bars that are buried by drilling and planting bars. The general drilling depth is 100mm (or 10d), but In this method, there are a series of processes that require drilling, cleaning, plastering, glueing, and test drawing. Any process will cause certain quality defects regardless of the quality of the raw materials, or the difference in construction level or the influence of operating conditions, which will affect the structure. Safety and applicability, if the wall reinforcement can be embedded in the structural concrete at one time, the quality of the pull-out resistance will be greatly improved. In addition to the widespread use of drilling and planting reinforcement, in the past, some methods were to place the reinforcement on the wall in advance. Set up the embedded parts of the steel plate, and weld the tension bars on the embedded parts after the formwork is removed. Although this method does not require drilling and planting bars, it needs to make the embedded parts in advance, and there are also defects such as weak welding of the steel bars. Another is to reserve Insert ribs, but there are also situations such as formwork drilling, formwork damage and formwork removal difficulties
