Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of building construction, in particular to a concrete anti-seepage precast block of window sill coping. BACKGROUND

[0002] When the masonry structure of the outer wall is constructed, the wall is built to the window sill position in the conventional outer wall masonry construction process to ensure the normal operation of each construction process, and after the formwork of the window sill coping is removed, the wall can be built to the top of the floor.

[0003] The construction time of each layer of the main body structure is short, and if the window is built first and then the wall construction is completed according to the normal process, the masonry and plastering process of the outer wall will be delayed, which will prolong the construction period, and the workers often leave a gap at the coping position of the window during the masonry construction to speed up the construction progress, and the window sill coping hole is formed by directly building up to the top, which inverts the process, and the window sill coping hole is filled or directly poured in the later period.

[0004] The disadvantages of the pre-existing gap are as follows: 1. There is no direct reference for the pre-existing gap on both sides of the window sill plate elevation, and the four gaps of the window are measured by a tape measure during construction, which deviates from the actual coping block size, resulting in that most of the pre-existing four gaps do not meet the design requirements, and the window sill plate is difficult to be poured into the two sides of the concrete at one time;

[0005] 2. When the window sill plate is a masonry wall, the existing construction method does not have a pre-existing window, which makes it difficult to arrange the longitudinal reinforcement in the subsequent construction, and the longitudinal reinforcement is often placed on the bottom block or placed vertically on the bottom block;

[0006] 3. The post-pouring process of the window sill coping will cause the concrete to solidify twice, which is easy to form a cold joint and cause leakage problems. The traditional precast block for coping is a square block, and the masonry construction may not be full due to the concrete mortar joint, which will cause rainwater to flow into the window sill and cause leakage.

[0007] Therefore, the utility model designs a concrete anti-seepage precast block for window sill coping to solve the above problems. CONTENT OF THE UTILITY MODEL
