Construction method for nonlinear type lintels

Abstract

The invention relates to a construction method for nonlinear type lintels. The construction method constituted by a construction method for the cast-in-place concrete lintels or a construction method for the prefabricated concrete lintels. The construction method for the cast-in-place concrete lintels comprises the following steps that (1) steel bars are bound, specifically, at a door opening and a window opening, the distribution bars needed in the L-shaped nonlinear type lintel, the U-shaped nonlinear type lintel, the Z-shaped nonlinear type lintel and the other nonlinear type lintels with the irregular shapes are machined to be formed in a steel bar machining area in advance according to the design requirements; (2) formworks are erected; (3) concrete is cast; (4) curing is conducted; and (5) the formworks are dismantled. The construction method for the prefabricated concrete lintels comprises the following steps that (1) sites are prepared, specifically, the prefabrication sites for the L-shaped nonlinear type lintel, the U-shaped nonlinear type lintel, the Z-shaped nonlinear type lintel and the other nonlinear type lintels with the irregular shapes are specially arranged on site; (2) the detailed design is conducted, specifically, the number of the nonlinear type lintels is counted in a classified mode in advance, and the machining sizes and the shapes of the nonlinear type lintels and the distribution bars in the lintels are designed; (3) the steel bars and the formworks are mounted; (4) the concrete is cast; (5) the formworks are dismantled; (6) stacking and curing are conducted; and (7) mounting is conducted. The process is simple, and the speed is high.

Description

technical field [0001] The invention relates to the technical field of masonry structures in building construction, in particular to a non-linear lintel construction method. Background technique [0002] In the construction of masonry structures, reinforced concrete lintels are indispensable on the top of reserved holes such as doors and window electrical boxes. There are two types of lintel construction: one is cast-in-place and the other is prefabricated. In order to meet the structural safety, seismic fortification requirements and design and construction requirements of these two types of lintels, both ends of the lintels must meet the minimum laying length. However, with the improvement of the living environment of modern people and the humanization of the use function, it brings difficulties to the structural construction. The design of indoor partition walls is getting thinner and thinner. Conventional kitchen and bathroom partition walls are designed to be 100mm th...

However, with the improvement of the living environment of modern people and the humanization of the use function, it brings difficulties to the structural construction.

The design of indoor partition walls is getting thinner and thinner. Conventional kitchen and bathroom partition walls are designed to be 100mm thick, and the design position of the door is mostly at the corner of the wall, so the shelving length of the lintel cannot meet the minimum requirements.
