Construction method of lightweight concrete batten partition door opening

Abstract

The invention discloses a construction method of a lightweight concrete batten partition door opening. Galvanization square steel pipes are adopted to replace concrete structural columns / jamb on dooror window and concrete lintels. The construction method has the advantages that construction is convenient, the construction quality is high, the construction period is short, energy is saved, and environment protection is achieved.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a construction method for a door opening of a lightweight concrete slab partition wall. Background technique [0002] Lightweight concrete slabs refer to the use of cement as the cementing material, steel bars, steel wire mesh or other materials as reinforcement materials, industrial ash such as fly ash, coal gangue, slag, recycled aggregates, natural light aggregates, artificial light aggregates, etc. Precast concrete slabs made of aggregate and mechanized according to the building modulus. Mainly used in the interior partition walls of buildings, it has the characteristics of light weight and high strength, thermal insulation, good sound insulation, high strength, green environmental protection, and convenient construction. [0003] At present, the door openings of lightweight concrete slab partition walls are mainly constructed with cast-in-situ concrete structu...

AI Technical Summary

Problems solved by technology

[0004] Through the above description of the construction scheme of the door opening of the lightweight concrete slab partition wall, it can be seen that the construction scheme has the following shortcomings: First, the structural column / embracing frame is vertically high and the cross section is small, and it cannot be observed The progress of concrete pouring, the concrete is not easy to vibrate and compact, so it is difficult to guarantee the construction quality of the structural column / frame; the second is that the construction column / frame is poured with a shovel to transport the concrete, and the pouring speed is too slow, which affects the structural column / frame The third is that the construction process of the doorway lintel is complicated, and the installation of the partition wall above the doorway lintel needs to wait for the cast-in-place concrete lintel to reach the corresponding strength before construction can be carried out, which takes too long, especially in winter. For a long time, it seriously affected the construction progress of the partition board
