Embodiment Construction

[0034] Such as Figure 1~3 As shown, a prefabricated column with a reserved bellows interspersed with longitudinal reinforcement includes a column body 1, and the upper and lower ends of the body of the column body 1 are respectively provided with a shear keyway 11, and the mortar poured in the shear keyway 11 can be solidified. Firmly connect the prefabricated columns on the upper and lower floors. A stirrup skeleton 2 and a corrugated pipe 3 are pre-embedded in the body of the column 1. The stirrup skeleton 2 includes several composite stirrups, and several composite stirrups are arranged at intervals from bottom to top. Each composite stirrup includes two rectangular stirrups. 21 and a square stirrup 22, two rectangular stirrups 21 are set in a cross and fixed inside the square stirrup 22, the use of composite stirrups has the characteristics of easy assembly, strong versatility and firm connection. Preferably, the middle part of the main body of the column 1 is a non-dens...

Abstract

The invention discloses a prefabricated column with reserved corrugated pipes inserted with longitudinal bars and a construction method thereof. The prefabricated column comprises a column body, wherein stirrup frameworks and corrugated pipes are pre-buried in the column body, the multiple corrugated pipes are vertically inserted in the stirrup frameworks, and all the corrugated pipes are fixed tothe stirrup frameworks. The technical problems that in an existing fabricated building, the requirement for the manufacturing precision of prefabricated columns is high, connection between upper-layer prefabricated columns and lower-layer prefabricated columns is not firm, and the construction cost is high can be solved.

Description

technical field [0001] The invention relates to the field of prefabricated buildings, in particular to a prefabricated column with a reserved bellows inserted through longitudinal reinforcement and a construction method thereof. Background technique [0002] In the current prefabricated concrete buildings, the upper and lower prefabricated columns are mostly connected by sleeves, that is, sleeves are buried at the bottom of the longitudinal reinforcement of the upper column, and a certain length of longitudinal reinforcement is protruded from the top of the lower column, and the longitudinal reinforcement of the lower column is inserted into the upper column. In the sleeve, the grout connection is then made through the sleeve. Due to the small inner diameter of the sleeve, high manufacturing precision is required so that the longitudinal bars can be inserted into the sleeve. If the manufacturing accuracy is insufficient, the steel bars cannot be inserted into the sleeve. The...
