[0010] Specific implementation manner two: combination Figure 1 ~ Figure 3 To illustrate this embodiment, each channel steel plate 1-1 of this embodiment also includes four bolt lug plates 1-1-4, and the outer side walls of two channel inclined die plates 1-1-3 are provided with One bolt lug plate 1-1-4, the other two bolt lug plates 1-1-4 are located under the two trough-shaped horizontal die pieces 1-1-2, and the other two bolt lug plates 1-1-4 are symmetrically arranged On the two side walls of the trough vertical mold piece 1-1-1. The other components and connection relationships are the same as in the first embodiment.

specific Embodiment approach 3

[0011] Specific implementation mode three: combination Figure 1 ~ Figure 3 This embodiment will be described. The construction method of the high-strength concrete oblique column conversion node that contains a steel frame restrained by this embodiment is described. The specific process of the construction method is as follows: firstly, the steel frame 2 is tied and formed; A channel steel plate 1-1 is supported, and the four bolt lugs 1-1-4 of the two channel steel plates 1-1 are fixed by bolts, and then along the seam of the two channel steel plates 1-1 Full butt welding makes the two channel steel plates 1-1 form a whole; finally, pour high-strength concrete 3 into the inner cavity of steel plate mold 1, and after curing and forming high-strength concrete 3 to reach the curing strength, steel plate mold 1, steel frame 2 And high-strength concrete 3 form a whole.

Abstract

The invention provides a reinforcement cage containing high-strength concrete batter post transferring node and a construction method thereof, relating to a reinforced concrete batter post transferring node and a construction method thereof. The invention solves the problems that the traditional reinforced concrete batter post transferring node has lower bearing capacity and certain friability and the traditional construction method of the reinforced concrete batter post transferring node is difficult to guarantee construction quality and has high manufacturing cost. Two oblique reinforcementcages are crossed and injected at the upper end of a rectangular solid frame, the obliquity of the two crossed oblique reinforcement cages is consistent with the obliquity of two groove type oblique mould pieces on a steel plate mould, and a horizontal reinforcement frame horizontally penetrates through the upper parts of a plurality of additional vertical bars. The construction method comprises the steps of binding and moulding the reinforcement cage, fixing four bolt lug plates of two groove type steel plates by virtue of bolts and carrying out full-length welding on the opposite joints along the joint of the two groove type steel plates so as to weld the two groove type steel plates into a whole. The invention is applied to a reinforced concrete transferring node formed by crossing twobatter posts at the upper part and an upright at the lower part.

Description

Technical field [0001] The invention relates to a reinforced concrete oblique column conversion node and a construction method thereof, in particular to a high-strength concrete oblique column conversion node constrained by a reinforced concrete skeleton and a construction method thereof, and belongs to the technical field of building structure engineering. Background technique [0002] The existing reinforced concrete node is formed by the confluence of two oblique columns on the upper part and a column on the lower part. The reinforced concrete node, as a conversion part of the vertical members of the upper and lower structure, is crucial to the overall force of the vertical structure. The external load causes certain bending deformation, oblique compression and lateral expansion deformation of this type of node, which are mainly borne by the core concrete and peripheral stirrups in the node area, resulting in a certain brittleness and low bearing capacity of the node, which is ...
