Abstract
This invention discloses a method for bracing concrete column by angle steer in the architectural engineering, in addition to its structure. The method comprises the following steps: a) making the angle steer assembly, that is, welding steer bar bolt in outboard of one limb of the angle steer, welding steer pipe in the other limb; b) setting up the assembly around the concrete column to be braced, each assembly are connected with each other through the steer bar bolt crossing the steer pipe; c) installing cap nut in the steer bar bolt and screwing up, which makes the nearside of each angle steer sticking to the surface of the concrete column. The structure comprises the angle steer, steer bar bolt and the steer pipe, and along the angle steer, the steer bar bolt and steer pipe are set alternatively, which forms interlace arrangement of the adjacent steer hoop.
Description
Technical field:
The present invention relates to adopt in the construction work method and the structure thereof of reinforcing concrete post using angle steel.
Background technology:
Beam in the building structure, post member, because of quality accident takes place in construction, or because of the load after the technological transformation surpasses design load, and cause insufficient strength to reinforce; With reinforced concrete post, reinforcement means commonly used has two kinds: the one, and angle steel on the tetra-pack of post is reinforced with the hoop binding between the angle steel; The 2nd, around post, respectively pour into a mould the thick steel concrete of 80mm at least, column section is increased, this reinforcement means is commonly called as " wearing wadded jacket ".Said method one, convenient simple and direct, expense is low, but because the inner corner trim in institute cornerite steel cross section is a circular arc, is difficult to be adjacent to the concrete column corner angle be integral, so pillar intensity increases and only has an appointment 12% behind the cornerite steel; Method two, consolidation effect is reliable, but time-consuming, and cost is very high.
Summary of the invention:
The objective of the invention is to: a kind of new method and structure thereof that adopts reinforcing concrete post using angle steel is provided, can solves institute's cornerite steel and concrete column and paste not tight problem, improve the intensity of concrete column, can reduce the expense of stabilization works again.
The present invention is achieved in that at first, makes the angle steel composite member, promptly at a limb lateral surface welded reinforcement bolt (2) of angle steel (1), at the lateral surface welded steel pipe (3) of another limb; Secondly, the angle steel composite member is arranged in the reinforced concrete post (4) that needs reinforcement around, pass steel pipe (3) by reinforcing bar bolt (2) between each angle steel composite member and be connected with each other; At last, go up installation nut (5) at reinforcing bar bolt (2), fastening nut (5) is adjacent to the medial surface of each angle steel (1) and the surface of reinforced concrete post (4).
On each limb of angle steel (1), all be furnished with reinforcing bar bolt (2) and steel pipe (3) at interval, form neighbouring stirrup interlaced arrangement.
Adopt the per pass hoop method of nutting (5) simultaneously, after single nut (5) was tightened by controlling value, the double nut of in good time screwing on again got loose preventing, and tightens in sequence.
Specification, the length of angle steel (1), reinforcing bar bolt (2), steel pipe (3) and nut (5) are decided on the design parameters of reinforced concrete post (4).
The present invention constitutes like this: it comprises angle steel (1), limb lateral surface welded reinforcement bolt (2) at angle steel (1), lateral surface welded steel pipe (3) at another limb, the surface of the inboard of angle steel (1) and reinforced concrete post (4) is adjacent to, and reinforcing bar bolt (2) passes steel pipe (3) and is connected with nut (5).
In the above constituted, reinforcing bar bolt (2) and steel pipe (3) arranged that being arranged as at interval of angle steel (1) length direction promptly the order of placement on a limb of angle steel (1) is reinforcing bar bolt (2), steel pipe (3), arrange at interval successively; Order of placement on another limb of angle steel (1) is steel pipe (3), reinforcing bar bolt (2), arranges at interval successively, forms the interlaced arrangement of adjacent stirrup; Reinforcing bar bolt (2) adopts double nut to connect with being connected of steel pipe (3).
The invention has the beneficial effects as follows: solved cornerite steel and concrete column and pasted not tight problem, can improve the intensity of concrete column, and can reduce the expense of stabilization works.
Description of drawings:
Fig. 1 is the schematic diagram of angle steel composite member of the present invention;
Fig. 2 is the sectional view of reinforced concrete column of the present invention;
Fig. 3 is the elevation of reinforced concrete column of the present invention.
The specific embodiment:
Embodiments of the invention:
At first, requirement of strength according to the geometric parameter and the bearing load of reinforced concrete post 4, specification, the length of angle steel 1, reinforcing bar bolt 2, steel pipe 3 and nut 5 is determined in design, determine the arrangement and the distance of neighbouring stirrup, requirement is on each limb of angle steel 1, all being furnished with reinforcing bar bolt 2 and steel pipe 3 at interval, is interlaced arrangement to form neighbouring stirrup.
Secondly, make the angle steel composite member, promptly at a limb lateral surface welded reinforcement bolt 2 of angle steel 1, lateral surface welded steel pipe 3 at another limb, reinforcing bar bolt 2 and steel pipe 3 are arranged being arranged as at interval of angle steel 1 length direction, promptly the order of placement on a limb of angle steel 1 is reinforcing bar bolt 2, steel pipe 3, arranges at interval successively; Order of placement on another limb of angle steel 1 is steel pipe 3, reinforcing bar bolt 2, arranges at interval successively; This angle steel composite member is made 4;
Then, 4 angle steel composite membeies be arranged in reinforced concrete post 4 around, pass steel pipe 3 by reinforcing bar bolt 2 between each angle steel composite member and be connected with each other;
At last, a nut 5 is installed earlier on reinforcing bar bolt 2, is made the screw-down torque of this nut 5 reach design load, treat surperficial sturdy being adjacent to of the medial surface of each angle steel 1 and reinforced concrete post 4 after, second nut of screwing on again prevents the purpose that gets loose to reach.Take the per pass hoop method of nutting simultaneously, after hoop is tightened together, twist the second road hoop again, carry out successively, until finishing.
After the reinforcing, the medial surface of each angle steel and the surface of concrete column are adjacent to fully, and this is because in nutting application of force process, and the concrete compression that concrete column is four jiaos squeezes and grinds off corner angle, are harmonious with the concave arc of angle cross section, and both are adjacent to comprehensively, stressed jointly.After testing, the present invention makes the intensity of concrete column improve 35%; And the reinforcing expense is cheap, only for wearing 26% of wadded jacket reinforcement means expense.
