Construction process for reinforced concrete beam bottom bracing and reinforcing template

Abstract

The invention relates to the construction field of cast-in-situ reinforced concrete building structure, in particular to a construction process for a reinforced concrete beam bottom bracing and reinforcing template. The process comprises the following steps: reinforcing a cast-in-situ reinforced concrete template by a process that a hole is drilled at the bottom of a beam-side template, and then a tie bolt passes through the hole and is fastened by a tie screw. The tie bolt adopted by the invention has strong tension, can effectively avoid the occurrence of deformation of the beam bottom, bulging die at beam side and the like, ensure accurate size, smooth surface, smooth and straight line and excellent impressions of the beam cross section, achieve the requirement of exposed concrete and directly omit the process of plastering lime and mortar layers for later decoration, thereby thoroughly and completely eradicating the possibilities of hollowness and falling, saving decoration manpower, thus the construction process is specially suitable for exposed concrete beam template projects such as large-scale variable cross-section beams, large-scale beams and the like.

Problems solved by technology

[0002] In the construction of cast-in-place reinforced concrete structures, fair-faced concrete can fundamentally solve the common problems of plastering mortar hollowing and falling of beams, slabs and columns due to its excellent appearance and saving a lot of plastering mortar and decoration labor, and significantly improve the project quality. , is chosen by more and more engineering projects—especially structural excellence projects. In order to achieve the effect of fair-faced concrete, formwork—especially the production and installation quality of beam formwork is the key. Traditional beam formwork production , Installation method Due to the inevitable shortcomings of beam side expansion mold, beam bottom deformation, beam bottom grout leakage, etc., it is often difficult to meet the strict requirements of fair-faced concrete; the combined steel formwork adopts steel formwork and its corresponding accessories (steel corrugated, pull bolts , U-shaped card, L-shaped bolt, etc.), although it has strong rigidity and flatness, the finished product is accurate in size, smooth in surface, straight in line, and good in appearance, meeting the requirements of fair-faced concrete, but because the surface of the finished product is too smooth , it often needs to be chiseled before entering the construction of the next process; although the steel formwork has a large number of turnovers, it requires a large investment and requires regular maintenance

Therefore, most construction companies are reluctant to use
