Reinforced concrete windowsill coping adverse construction method

Abstract

The invention relates to a reinforced concrete windowsill coping adverse construction method comprising the following steps: (1) making pre-cast reinforced concrete building blocks; (2) removing a form; (3) maintaining the pre-cast reinforced concrete building blocks; (4) laying a masonry; (5) burying the pre-cast reinforced concrete building blocks; (6) welding windowsill coping reinforcing steel bars with reinforcing steel bars reserved for the reinforced concrete building blocks; (7) making a template; and (8) processing the joint of the template and the wall. The reinforced concrete windowsill coping adverse construction method can ensure that the reinforced concrete windowsill coping construction is not restricted by the length of the windowsill coping, guarantee the compact construction joint and greatly improve the windowsill coping construction progress and the windowsill coping construction quality. In addition, the reinforced concrete windowsill coping adverse construction method is simple and is convenient to operate. Moreover, the reinforced concrete windowsill coping adverse construction method uses the filed concrete construction residual material to make the pre-cast reinforced concrete building blocks, thereby causing no pollution to the environment and saving the energy and the windowsill coping construction cost.

Description

technical field [0001] The invention relates to an industrial and civil construction engineering method, in particular to a reinforced concrete window sill top pressing and reverse construction method. Background technique [0002] In the housing construction project, the reinforced concrete window sill is used to prevent 45° cracks at the two corners of the lower part of the window sill, and water seepage from the window sill enters the wall under the window sill, causing quality problems such as water intrusion into the wall. The traditional general methods are as follows: firstly, when building the wall, the reinforced concrete window sill top is poured when the masonry reaches the window sill position, and the brickwork is continued after the reinforced concrete top is poured. The long interval of wall masonry affects the construction period. 2. When building the wall, when it reaches the position of the window sill, first use the supporting block to support it, and dire...

Problems solved by technology

The traditional general methods are as follows: firstly, when building the wall, the reinforced concrete window sill top is poured when the masonry reaches the window sill position, and the brickwork is continued after the reinforced concrete top is poured. The long interval of wall masonry affects the construction period. 2. When building the wall, when it reaches the position of the window sill, first use the supporting block to support it, and directly build the upper wall on it. When the reinforced concrete window sill is pressed to the top, remove the supporting block and then pour the concrete When the window sill is pressed to the top, the quality of the overhanging part of the upper part of the window sill will be affected when the support block is removed. The cumbersomeness results in a waste of labor and waste of materials; third, the prefabricated window sill is limited by the length of the window sill, the finished product is not suitable for protection, and the construction operation is cumbersome, etc.
