Problems solved by technology

However, if some links are not noticed during the construction process, if the support is not strong or not set up according to the specification requirements, the construction quality of the post-cast belt will be affected, and a series of problems such as cracking and beam head drop will follow one after another. It will make the post-pouring belt not play its due role, and may also bring inconvenience to the construction and cause hidden dangers to the structure

Embodiment Construction

[0017] The application of the plain concrete column of the present invention in post-cast belt support comprises the following steps:

[0018] Selection of corrugated pipe→opening of beam bottom plate→installation and reinforcement of corrugated pipe→pouring of plain concrete column→removal of formwork support→installation of formwork support and concrete pouring after casting→removal of plain concrete column.

[0019] Wherein, in the process of selecting the bellows, the diameter of the bellows is 200-300 mm, more preferably 200 mm.

[0020] In the process of opening the beam bottom plate, after the floor formwork is erected and before the beam bottom plate is installed, holes are opened on the beam bottom plate according to the position set by the post-casting belt, and the hole margin is set at 200-500mm from the post-casting belt (ie The distance between the edge of the hole closest to the post-casting tape and the post-casting tape is 200-500mm), and the diameter ...

Abstract

The invention discloses the application of plain concrete columns to later-poured strip supporting and belongs to the technical field of construction. The application of the plain concrete columns to later-poured strip supporting sequentially includes the steps of selection of bellows, hole forming of beam base plates, mounting and reinforcing of the bellows, the pouring of plain concrete columns, removal of formwork supports, building of later-poured strip formwork supports and pouring of concrete and removal of the plain concrete columns. According to the application of the plain concrete columns to later-poured strip supporting, the formwork supports previously arranged in a full span mode can be replaced with the plain concrete columns, so that a lot of revolving materials such as steel tubes and fasteners are saved in the long wait in the construction of a main structure, a certain effect of the civilization construction in a construction site is obtained, the construction site after the completion of later-poured strip construction is cleaned, the risk of construction in the site is reduced for workers, the quality of later-poured strip construction is ensured, and a lot of benefits are achieved at the same time.

Description

technical field [0001] The invention discloses the application of a plain concrete column in post-cast belt support, and belongs to the technical field of building construction. Background technique [0002] Post-pouring tape has been widely used as an alternative technical measure to leave no temperature expansion joints in super-long buildings and no settlement joints between high-rise parts and skirt rooms of high-rise buildings. However, if some links are not noticed during the construction process, if the support is not strong or not set up according to the specification requirements, the construction quality of the post-cast belt will be affected, and a series of problems such as cracking and beam head drop will follow one after another. It will make the post-pouring belt fail to play its due role, and may also bring inconvenience to the construction and cause hidden dangers to the structure. Contents of the invention [0003] The purpose of the present inventio...
