Problems solved by technology
[0005] The purpose of the present invention is to design a formwork-free system and construction method for post-settlement poured belts, using pre-embedded channel steel and checkered steel plates connected with pre-embedded channel steels as the stress system to replace conventional steel pipe fastener type post-cast belt formwork It solves the problem that the support at the pouring belt after settlement stays for too long, which affects the subsequent process construction and thus affects the overall construction progress. It has the advantages of safety, reliability, fast construction speed, convenient construction, saving construction cost and better guaranteeing construction quality.

Embodiment
[0041] The post-settlement cast belt formwork-free system uses pre-embedded channel steel and checkered steel plate connected with the pre-embedded channel steel as the stress system instead of the conventional steel pipe fastener-type post-cast belt formwork frame, which solves the problem of remaining brackets at the post-settlement cast belt The problem that the time is too long will affect the construction of the subsequent process and thus affect the overall construction progress. It has the advantages of safety, reliability, fast construction speed, convenient construction, saving construction cost and better guarantee of construction quality, such as Figure 1-Figure 6 As shown, specifically set to the following structure:
[0042] Basically, the formwork-free system of the post-settlement cast belt includes a side structure 1 of the post-settlement cast belt, a post-settlement cast belt 2, a left embedded channel steel 3, a right embedded channel steel 4 and a steel pla...

The invention provides a formwork-free system and a construction method for a post-settlement poured belt, and relates to the technical field of building construction. Channel steel and steel plate; the left embedded channel steel and the right embedded channel steel are pre-embedded in the side structure of the poured belt after settlement to form a stressed whole with it, and the left embedded channel steel and the right embedded channel steel The cantilever section is connected by bolts in the post-settlement pouring zone and allows the relative displacement of the left embedded channel steel and the right embedded channel steel in the vertical direction, and the left embedded channel steel and the right embedded channel steel The hanging steel plate is used as the formwork of the poured belt after settlement. The present invention uses embedded channel steel and checkered steel plate connected with the embedded channel steel as the stress system to replace the conventional steel pipe fastener type post-cast belt formwork support, which solves the problem that the support at the post-settlement belt stays for too long and affects the follow-up process Construction and then affect the overall construction progress.
Description
technical field [0001] The invention relates to the technical field of building construction, in particular to a post-settlement pouring belt formwork-free system and a construction method thereof. Background technique [0002] With the development of the building level and people's demand for building space, the building forms of high-rise and super high-rise buildings with low-rise podiums and underground garages are becoming more and more common. Due to differences in settlement, post-settlement pouring strips are usually set up in low-rise buildings and underground garages around high-rise buildings. The post-settlement pouring strips will generally be kept until about 45 days after the main structure of the high-rise building is capped, and then poured after the settlement is stable. During this period , the structural reinforcement at the poured belt after settlement is connected but the concrete is not connected, and the structures on both sides of the poured belt aft...
