Problems solved by technology
[0005] The fastener-type steel pipe formwork support system in the existing practice mainly has the following problems: the fastener-type steel pipe formwork support system, the vertical poles are arranged densely, the distance between the vertical poles is about 1m, and the vertical and horizontal poles and scissors There are many supports and the support system is relatively complicated. Since the fastener-type steel pipe formwork in the post-casting belt area needs to be stored for a long time, it is inconvenient to transport materials and garbage during the later construction process.
In addition, the support system in the post-casting belt area is left for a long time, which not only causes a large number of steel pipes, fasteners and jacking brackets to fail to turn around effectively, but also causes different degrees of corrosion, deformation, rot and slippage of the main components, etc. The material rental cost and labor maintenance cost are relatively large

Embodiment Construction
[0037] see Figure 1 to Figure 8 shown.
[0038] figure 1 and figure 2 It is a schematic diagram of the concrete support column after the fastener type steel pipe formwork support system including the area where the post-casting belt is located is removed in step S6 of the present invention. Wherein the reference numeral 7 is a beam, and the concrete support column is connected with the main body (floor or beam). The reference number 2 in the figure is the pouring area of the post-casting belt 2, that is, the construction joint of the post-casting belt;
[0039] image 3 and Figure 4 In order to set up the whole floor slab including the fastener-type steel pipe formwork support system in the area where the post-casting belt is located, and the schematic diagram of the pipe form at the post-casting belt.
[0040] Such as Figure 5 As shown, the structure of the first steel skeleton and the second steel skeleton is the same, but the height is different, so only one pi...

The invention provides a construction method for a post-pouring belt formwork supporting system. A floor entirety including a fastener type steel pipe formwork supporting system located in the area where a post-pouring belt is located is built at first according to the existing technology, and post-pouring belt construction joint setting up is conducted at the preset position according to a construction drawing based on the existing technology; then, the two sides of the post-pouring belt are symmetrically provided with two rows of pipe molds, after the floor and the pipe molds are poured, andconcrete meets the requirements, at the moment, concrete supporting columns are formed at the pipe molds, accordingly, the entirety including the fastener type steel pipe formwork supporting system located in the area where the post-pouring belt is located can be dismantled, the occupied time for a fastener type steel pipe formwork on steel pipes, fasteners and jacks at the post-pouring belt is shortened, the using effect is better improved, and the material cost is reduced greatly.
Description
technical field [0001] The invention relates to the technical field of building construction, in particular to a construction method of a post-cast belt formwork support system. Background technique [0002] With the vigorous development of construction technology in my country's construction industry, high-rise and super high-rise buildings are springing up everywhere, and the volume and scale of buildings are also increasing. When it is used, it is often necessary to set up post-casting belts at the corresponding positions to prevent harmful cracks that may occur in cast-in-place reinforced concrete structures due to uneven temperature and shrinkage. [0003] The post-pouring belt is a temporary part set at the corresponding positions of the foundation floor, wall and beam in order to prevent the harmful cracks that may occur in the cast-in-place reinforced concrete structure due to uneven shrinkage or uneven settlement during construction. construction joints. Therefore,...
