A device and method for early maintenance of cast-in-place concrete walls

Abstract

The invention provides a cast-in-place concrete wall surface earlier-stage curing device comprising a water supplying pipe. The side wall of the water supplying pipe is attached and fixed to the innerside wall of an internal corner formwork at the top of a concrete wall, and the attaching area of the side wall of the water supplying pipe and the inner side wall of the internal corner formwork isinternally provided with a water out seam parallel to the center axis of the water supplying pipe. An arc-shaped opening is formed in the other pipe side wall, opposite to the pipe side wall where thewater out seam is formed, of the water supplying pipe, the water supplying pipe is internally provided with a valve capable of opening / closing the water out seam, and the valve comprises a circular-arc-shaped steel plate and a handle fixed to the circular-arc-shaped and provided with the free end extending out of the arc-shaped opening. The outer wall of the circular-arc-shaped steel plate and the inner wall of the water supplying pipe are arranged in an attached mode, the center axis of a cylinder where the circular-arc-shaped steel plate is located coincides with the center axis of a cylinder where the water supplying pipe is located, and the circular-arc-shaped steel plate has a hood face area capable of completely covering the water out seam. According to the cast-in-place concrete wall surface earlier-stage curing device, earlier-stage advance curing of the concrete wall surface before formwork dismounting can be achieved, and generation and development of cracks in the concretesurface due to earlier-stage unqualified curing are effectively prevented.

Description

technical field [0001] The invention relates to the fields of municipal engineering and building construction, in particular to an early maintenance device and method for cast-in-situ concrete walls. Background technique [0002] At present, in building construction, it is generally necessary to moisturize and maintain the concrete within a certain period of time after the concrete is poured to prevent cracking. The strength of vertical concrete components such as walls and columns as load-bearing in concrete structures is the key to on-site quality control, so the early maintenance of such components is very important, especially the maintenance before formwork removal. At present, most of the maintenance of such components on the construction site adopts manual watering maintenance after demolition, or covering and water conservation maintenance, which cannot achieve the effect of early maintenance. Moreover, for horizontal components, such as concrete slabs, watering and...

Problems solved by technology

However, for concrete walls, it can neither be wrapped like a column, nor is it easy to cover and maintain water on the surface like a concrete slab. At present, the maintenance of the walls, especially the inner walls, at the construction site must wait until the walls are demolished. Artificial watering maintenance, or brushing curing agent

This maintenance method not only has the problems of uneven maintenance and waste of water resources, but also the maintenance after the removal of the formwork will cause untimely maintenance, resulting in cracks on the wall and affecting the quality of the wall, especially in the basement and underground comprehensive pipe gallery. Cracks in the walls of underground structures can cause water seepage and cause huge damage
