An m-shaped assembled grout-retaining steel plate for a sloping roof and its construction method

Abstract

The invention discloses an M-shaped assembled slurry-retaining steel plate for a sloping roof and a construction method thereof. It includes a first horizontal plate and a second horizontal plate arranged symmetrically in parallel, the first horizontal plate is fixedly connected to the first inclined plate, the second horizontal plate is fixedly connected to the second inclined plate, and the gap between the first inclined plate and the second inclined plate The vertical board perpendicular to the first horizontal board and the second horizontal board is fixedly connected, and the first buckle is fixedly connected to the second horizontal board. The invention can indirectly reduce the flow rate of concrete poured on the sloped roof, ensures that the concrete is compacted by vibration, and can effectively reduce the number of construction joints during layered pouring. At the same time, it can be a support for double-layer two-way slab steel bars on inclined roofs. Effectively ensure the effective thickness of the steel bars on the sloping roof structure. The operation is convenient, the cost is low, the process is simple, safe and reliable, economical and practical, and the quality hidden danger of the inclined roof concrete structure can be effectively avoided.

Description

technical field [0001] The invention relates to the technical field of sloping roof construction, in particular to an M-shaped assembled grout-retaining steel plate for sloping roofs and a construction method thereof. Background technique [0002] With the development of the economy and the improvement of people's living standards, various housing constructions such as commercial housing and resettlement housing are becoming more and more common. In order to improve the aesthetics of the building, the main body of the general building usually increases the aesthetics of the main body by designing a sloping roof. As one of the main decorative structures of the house, the sloped roof often has frequent water leakage problems due to poor concrete pouring quality. At present, in the construction process of concrete pouring on sloped roofs of buildings, in order to improve the quality of concrete pouring on sloped roofs, technical measures are often used to change the slump of co...

AI Technical Summary

Problems solved by technology

However, in this traditional concrete pouring method for sloped roofs, because the concrete slump will change the characteristics of the concrete, there are often hidden quality problems, such as segregation, short initial setting time and other concrete-related quality problems. After the final setting of the concrete, internal due to Quality problems There are a lot of cracks, which not only cause major quality problems, but also shorten the service life of the structure, which may lead to structural safety problems in the later stage
