Construction process for wood mark facing fair-faced concrete

Abstract

The invention relates to a construction process for wood mark facing fair-faced concrete. The process comprises the following steps: performing three-side planing on wood laths, thereby obtaining wood mark molded panels; performing spot welding fixation on a square steel keel and steel pipes, and forming a keel frame; tiling back plates and fixing on the square steel keel of the keel frame, and planing the bottom sides of the back plates; tightly splicing the panels to the back plates, and controlling the lath gaps of the panels to be less than 1mm, wherein the height difference is less than 0.5mm, an internal corner of 45 degrees is obliquely planed, and two sides of the internal corner are tightly spliced; fixing by adopting a three-section through-wall split bolt after a template is lifted in place, and adjusting the perpendicularity and flatness; and removing the formwork after pouring concrete within 7 days. The construction process disclosed by the invention is simple, high in operability, economic and reasonable, and the obtained wood mark facing fair-faced concrete is natural and clear in wood texture marks and good in effect.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a construction technique of fair-faced concrete with wooden traces. Background technique [0002] At present, fair-faced concrete with wooden traces is rarely seen in the country, and it is the first in Guangxi. The following technical difficulties exist in the construction of fair-faced concrete with wood trace finish: [0003] 1. The existing design drawings only indicate that there must be wood marks on the concrete, but the specific surface effect of the wood marks can only be determined after the construction of the model wall, and it is difficult to find the implementation direction before construction. [0004] 2. The quality of the finished product on the concrete surface must meet the standard of facing clear-faced concrete. When the formwork is made, the height difference between two adjacent formworks shall not exceed 1mm, the verticality of the installa...

AI Technical Summary

Problems solved by technology

[0003] 1. The existing design drawings only indicate that there must be wood marks on the concrete, but the specific surface effect of the wood marks can only be determined after the construction of the model wall, and it is difficult to find the implementation direction before construction

[0004] 2. The quality of the finished product on the concrete surface must meet the standard of facing clear-faced concrete. When the formwork is made, the height difference between two adjacent formworks shall not exceed 1mm, the verticality of the installation shall not exceed 3mm, the flatness shall not exceed 2mm, and the angles of the yin and yang shall be straight. , it is more difficult to manufacture and install, and the formwork system is different from ordinary concrete, so it is difficult for workers to fully understand

[0005] 3. After pouring the concrete, there must be some concrete grout stuck between the wood trace texture of the wooden slats, which cannot be cleaned manually and restored to the original state. It needs to be re-spliced ​​with new boards, and the cost is huge.
