Construction method of upper-layer prefabricated vertical component

Abstract

The invention discloses a construction method of an upper-layer prefabricated vertical component, which comprises the following steps of: installing a lower-layer supporting device in each floor slab hole through a step S2 after the step S1, limiting the displacement of a supporting piece by using a lower-layer supporting structure, and hoisting the upper-layer prefabricated vertical component through a lower-layer supporting structure after the upper-layer prefabricated vertical component is hoisted in a step S3. Effective lateral supporting and anti-overturning supporting are provided for the upper-layer prefabricated vertical component through a plurality of independent upper-layer supporting devices with supporting pieces as stable fulcrums in the step S4, so that formwork installation and concrete pouring can be carried out under the condition that the upper-layer prefabricated vertical component is in a stable state in the step S5 and the step S6; therefore, one-time pouring of the concrete of the post-pouring connection section and the cast-in-place concrete of the upper floor slab can be achieved, improvement of the structural strength of a building is facilitated, and the construction period can be shortened.

Description

technical field [0001] The invention relates to a prefabricated construction method of an assembled building, in particular to a construction method of an upper prefabricated vertical component. Background technique [0002] At present, prefabricated buildings are vigorously developed in the field of industrial and civil construction, and prefabricated vertical components such as prefabricated columns and prefabricated walls are also widely used in public buildings and civil buildings. [0003] like figure 1 As shown, during the construction of the current prefabricated building structure, after the construction of the lower floor and the lower vertical member 2 is completed, the upper prefabricated vertical member 3 needs to be hoisted to the top surface of the lower vertical member 2, and the upper floor After the prefabricated vertical member 3 is installed with a stable diagonal support, ie, the upper strut 8 in the figure, concrete is poured to combine the upper prefab...

AI Technical Summary

Problems solved by technology

[0004] In the prior art, when the upper floor 4 adopts a cast-in-place floor slab or floor deck structure, after the reinforcement of the cast-in-place floor slab or the floor deck is installed, the concrete pouring of the cast-in-place floor or floor deck structure is completed first, Then install the upper strut 8 in the figure on the upper floor 4 to provide stable oblique support for the upper prefabricated vertical member 3, so as to avoid the reinforcement of the upper floor 4 before the concrete is poured or the floor deck It is impossible to provide a reliable fulcrum for the upper strut 8; this method has the following disadvantages: since it is necessary to complete the concrete pouring of the upper floor 4 first, wait until the strength of the concrete reaches the standard, and then install the oblique support of the upper prefabricated vertical member 3. The upper strut 8 leads to: the construction period of the upper prefabricated vertical member 3 is long, which affects the construction speed of the building, and the concrete of the connecting node between the upper prefabricated vertical member 3 and the lower vertical member 2 and the concrete of the upper floor 4 cannot Realize integrated pouring, affecting the structural strength of the building
