Construction method of pre-embedded iron for special-shaped branches of trenches

Abstract

The invention provides a construction method for embedding iron into a special-shaped trench support opening. The construction method comprises the steps that 1, the positions and the shape structures of embedded iron pieces needing to be arranged in the special-shaped trench support opening are determined; 2, an integrated embedded iron structure is designed, determined and subjected to compliance approval; 3, all components of the integrated embedded iron structure are prefabricated; 4, all the related components in the integrated embedded iron structure are welded in advance on site to form a locally integrated embedded iron structure; 5, the locally integrated embedded iron structure is installed and reinforced after rechecking; 6, the other embedded iron pieces and the locally integrated embedded iron structure are welded to form a whole body; 7, steel bar binding and concrete pouring are conducted. According to the construction method, the project quality can be improved, the construction period can be shortened, and the labor cost and building material consumption can be reduced.

Description

technical field [0001] The invention relates to the technical field of pre-embedded iron treatment in building construction, in particular to a construction method for pre-embedded iron at a special-shaped branch of a trench in the construction process. Background technique [0002] In the process of building construction, it is often necessary to carry out the construction of embedded iron. The construction of pre-embedded iron parts in a regular building structure is less difficult and the construction method is mature. However, the construction difficulty of pre-embedded iron parts in complex building structures such as special-shaped branches in buildings is greatly increased. Such as figure 1 The service function of the repair trench in the automobile repair and maintenance workshop shown in the figure determines that the style of the branch part of the repair trench is complex, and many embedded iron parts are required. Accurate location and high overall flatness ar...

However, the construction difficulty of pre-embedded iron parts in complex building structures such as special-shaped branches in buildings is greatly increased.

like figure 1 The service function of the repair trench in the automobile repair and maintenance workshop shown in the figure determines that the style of the branch part of the repair trench is complex, and many embedded iron parts are required. Precise location and high overall flatness are required, the distance between the embedded irons must be accurate and the elevation control must be in place; thus making the construction of the embedded irons more difficult

[0003] The common method of pre-embedded iron construction for the above-mentioned special-shaped branch is in such as figure 1 A total of 6 embedded iron pieces A, B, C, D, E, and F are installed at the positions shown. During the construction process, each number of embedded irons is set up separately, and the carpenter and the placement worker cooperate with each other. : The position of the pre-embedded iron that needs to be set is tight, which makes it difficult to support the formwork, difficult to reinforce, and easy to run and explode the formwork; the cross-construction of various types of work affects each other, making the construction period longer; the amount of formwork is large, resulting in waste of wood, which is not environmentally friendly; The pre-embedded iron parts set independently are easy to deform, the overall quality is difficult to guarantee, and there is a risk of rework
