Construction method for indwelling concrete terrace expansion joint
The invention discloses a construction method for retaining a concrete floor expansion joint, which comprises the following steps of: inserting a joint retaining device into concrete in a slurry extracting and smoothing stage of the concrete, and pulling out the joint retaining device when the concrete is dried and solidified to reach the strength for people to get on, so that the expansion joint can be obtained, noise pollution caused by joint cutting is avoided, and the construction efficiency is improved. In addition, a large amount of flying dust in the traditional technology can be avoided, so that environmental pollution caused by the flying dust is avoided, and the method is environment-friendly; in addition, the situation that the concrete terrace is damaged due to disordered cracking caused by thermal expansion and cold contraction due to the fact that concrete curing is not timely or joint cutting is not timely can be avoided from the source; and moreover, compared with the mode that joints are cut one by one after the concrete is dried and solidified to a certain strength, the time needed for pulling out all the joint reserving devices is obviously shortened, and therefore the construction period of the whole concrete floor is shortened.
本发明公开了一种留置混凝土地坪伸缩缝的施工方法，其在混凝土的提浆收光阶段将留缝装置插入混凝土内，在混凝土干燥固化到能上人的强度时把留缝装置拔出来，即可得到伸缩缝，如此，不但避免了切缝引起的噪声污染，而且还可避免传统技术中大量扬尘的产生，从而避免了因扬尘导致的环境污染，即本发明方法环保；此外，还能从源头上避免了因为混凝土养护不及时或者切缝不及时而导致的混凝土地坪因为热胀冷缩而无序开裂被破坏的情况；再者，比起在混凝土干燥固化到一定强度后一条一条切缝，拔下各留缝装置需要的时间明显要少很多，从而本发明缩短了整个混凝土地坪施工周期。
