specific Embodiment 1

[0015] Such as figure 1 A reinforced concrete column shown includes a concrete column 3 and a reinforcement skeleton embedded in the concrete column. The reinforcement skeleton includes a plurality of longitudinal reinforcements and a plurality of stirrups 2. There are 16 longitudinal reinforcements 1, and the number of longitudinal reinforcements can be Determined according to design requirements, all longitudinal bars 1 are evenly distributed on a circle, each stirrup 2 includes a plurality of stacked elliptical ring steel bars 2-1, and all elliptical ring steel bars 2-1 in each stirrup 2 The middle parts of the elliptical rings are stacked and the vertices of the major axes are staggered. The number of elliptical ring steel bars 2-1 is half of the number of longitudinal bars 1. The adjacent elliptical ring steel bars 2-1 are fixed by steel wires. Each elliptical ring steel bar 2-1 is set in two Outside the opposite longitudinal bars 1, the major axis endpoints of the ellipt...

specific Embodiment 2

[0018] Such as image 3 As shown, the difference between the second embodiment and the first embodiment is that the length of the minor axis of the elliptical ring steel bar 2-1 is closer to the length of the major axis. Preferably, the length of the minor axis of the elliptical ring steel bar 2-1 is 4 / 5-7 / 8 of the length of the major axis.

[0019] The minor axis of the elliptical ring steel bar is 4 / 5-7 / 8 of the major axis, and the concrete column is a hollow concrete column. In this way, the stirrups 2 form a grid with a smaller area in the circle where the longitudinal bars 1 are arranged, which is suitable for making the concrete column 3 into a hollow concrete column to form a concrete pipe column.

[0020] The construction method of specific embodiment two is the same as specific embodiment one.

Abstract

The invention discloses a reinforced concrete column and a construction method thereof. The number of longitudinal bars is an even number above four, and all the longitudinal bars are evenly distributed on a circumference. Each reinforcement stirrup comprises a plurality of elliptical ring steel bars which are stacked up together. The middle portions of all the elliptical ring steel bars of each reinforcement stirrup are overlapped while long axis vertexes of each reinforcement stirrup are staggered. The number of the elliptical ring steel bars is half of that of the longitudinal bars. In the construction process, the reinforcement stirrups are manufactured firstly and reinforcement stirrup tools are adopted. Each reinforcement stirrup tool comprises a circular base, a plurality of circles of concentric longitudinal bar inserting holes are formed in the base, and the longitudinal bar inserting holes are evenly distributed in each circle. The corresponding longitudinal bar inserting holes are selected, and then 10-30cm bar bodies which are the same as the longitudinal bars in external diameter are inserted into the longitudinal bar inserting holes. Due to the fact that the reinforcement stirrups are formed by the elliptical ring steel bars and can be prefabricated, when the reinforced concrete column is installed, as long as one elliptical ring steel bar aligns to one group of longitudinal bars, the other elliptical ring steel bars will automatically align to the other groups of longitudinal bars. Therefore, the longitudinal bars can be sleeved with the reinforcement stirrups conveniently, connecting points are all located on the periphery of a framework of steel reinforcement when the reinforcement stirrups are connected with the longitudinal bars, and manual binding is facilitated.

Description

technical field [0001] The invention relates to a reinforced concrete column and a construction method thereof. Background technique [0002] The existing reinforced concrete column includes a reinforced skeleton and a concrete column, and the reinforced skeleton includes longitudinal bars and stirrups. Stirrups are generally a plurality of horizontal steel bars arranged in a square grid. The intersecting horizontal steel bars need to be fixed by steel wires, and the stirrups are then fixed to the longitudinal bars by steel wires. Therefore, there are many points that require workers to fix with steel wires. The processing efficiency is low. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a reinforced concrete column that is easy to process and manufacture, and to provide a construction method for a reinforced concrete column with fast construction speed. [0004] In order to solve the above-mentioned technica...
