Embodiment Construction

[0017] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0018] see Figure 1 to Figure 4 , a construction method for the external protection of a prefabricated concrete structure, carried out according to the following steps:

[0019] First of all, when making the prefabricated wall, the prefabricated wall inner leaf 1 is pre-embedded in the pre-embedded casing 4 for inserting the outer guardrail 5, and the fixed steel bars 6 are connected between the pre-embedded casings 4. 6. Fix the embedded casing 4 in the prefabricated wall.

[0020] Then during the on-site construction, the prefabricated wall body is installed, and the peripheral guard railing 5 is inserted into the embedded casing 4. After the prefabricated floor slab 7 is installed, when the concrete 8 is poured after pouring, the peripheral guard railing 5 is removed. Finally the post-cast concrete 8 is poured and the sleeves 4 in the prefabrica...

Abstract

The invention relates to a building construction method, in particular to an external enclosure construction method of a fabricated concrete structure. The construction method comprises the followingsteps that when a prefabricated wall is manufactured, an embedded sleeve for an external enclosure railing to insert is pre-embedded in the prefabricated wall; during site construction, the prefabricated wall is installed and then the external enclosure railing is inserted into the embedded sleeve; and after a prefabricated floor is installed, when post-poured concrete is poured, the external enclosure railing is removed and the embedded sleeve is sealed with the post-poured concrete. According to the external enclosure construction method of the fabricated concrete structure, the situation that a scaffold is erected outside the wall to install an enclosure is effectively avoided, at the same time, drilling on the prefabricated wall is avoided, late wall repair is reduced, labor is saved greatly and the construction period is shortened greatly.

Description

technical field [0001] The invention relates to a building construction method, in particular to a construction method for the external protection of an assembled concrete structure. Background technique [0002] In the traditional prefabricated concrete structure external enclosure installation project, scaffolding needs to be erected in advance, and the fixing of scaffolding and the installation of external guardrails need to drill holes in the prefabricated wall and fix them with bolts. In the above method, since the wall body needs to be drilled, the wall structure will be damaged, and the wall body needs to be repaired when the outer protection is removed. Contents of the invention [0003] The present invention aims at the above-mentioned problems existing in the prior art, and provides a construction method for the outer protection of an assembled concrete structure. The method does not need to drill holes in the wall body, and the installation and removal of the ou...
