Embodiment 1

[0027] Such as Figure 1 to Figure 3 As shown, the present embodiment provides a ring beam main reinforcement structure 100 at the ring beam node by the reverse construction method, including at least one layer of ring beam main reinforcement 10 . The main reinforcement 10 of each ring beam is processed from two semicircular steel bars. The two semicircular reinforcing bars are the first semicircular reinforcing bar 11 and the second semicircular reinforcing bar 12 . The diameters of the two semicircular bars are equal. That is, the diameters of the first semicircular reinforcing bar 11 and the second semicircular reinforcing bar 12 are equal. The perimeter of each semicircular steel bar is longer than half of the perimeter of the ring beam main bar 10 . That is, the perimeter lengths of the first semicircular steel bar 11 and the second semicircular steel bar 12 are both longer than half of the perimeter length of the ring beam main bar 10 . Two semicircular steel bars, t...

Embodiment 2

[0036] see Figure 1-Figure 3 , the present invention also provides a method for manufacturing the ring beam main reinforcement structure at the ring beam node of the reverse method, which is operated according to the following steps:

[0037] Process two two semicircular reinforcing bars, i.e. the first semicircular reinforcing bar 11 and the second semicircular reinforcing bar 12;

[0038] Put two semicircular steel bars in place from both sides of the steel pipe column, that is, put the first semicircular steel bar 11 and the second semicircular steel bar 12 in place from both sides of the steel pipe column;

[0039] Welding is carried out in the form of lap welding to form a closed ring beam main reinforcement 10, see image 3 , successively manufacture the ring beam main reinforcement 10 of each layer until the ring beam main reinforcement structure 100 is completed.

[0040] The method of the present invention solves the problem of difficult placement and closed weldin...

Abstract

The invention discloses a ring beam main reinforcement structure at a top-down construction ring beam joint and a manufacturing method and belongs to the field of building construction. The ring beammain reinforcement structure comprises at least one layer of ring beam main reinforcement. Each layer of the ring beam main reinforcement is formed by machining two semicircular steel bars. The diameters of the two semicircular steel bars are equal. The perimeter of each semicircular steel bar is greater than half of the perimeter of the ring beam main reinforcement. The two semicircular steel bars are arranged on the two sides of a steel tube column correspondingly, are arranged in position from the two sides of the steel tube column and are welded together in an overlap welding mode to formthe closed ring beam main reinforcement. Through optimization and adjustment of the ring beam main reinforcement, the problem that it is hard to arrange a ring beam main reinforcement in position andclosing welding is difficult are solved well, the in-position efficiency of the ring beam main reinforcement and the steel tube column is improved by 50%, and the construction quality of closing welding of the ring beam main reinforcement is ensured.

Description

technical field [0001] The invention relates to a structure and a manufacturing method of a main reinforcement of a ring beam at a node of a ring beam by an upside-down method, and belongs to the field of building construction. Background technique [0002] The beam-column joint of the upside-down method refers to the circular beam or rectangular beam joint at the connection between the structural steel pipe column and the structural beam of the basement under the construction condition of the upside-down method. The reinforcement structure of this node is relatively complex, generally circular or rectangular. When ring beam joints (hereinafter referred to as ring beams) are used, the ring beam main reinforcement (also called waist reinforcement) also needs to be processed into a ring, and then connected by lap welding or mechanical connection to form a closed ring reinforcement. [0003] However, the main reinforcement of the ring beam is generally large in size, with a di...
