CN102635239A - Method for anchoring welding wire-mesh reinforcement on floorslab bottom into support - Google Patents

Abstract

The invention relates to a method for anchoring welding wire-mesh reinforcement on a floorslab bottom into a support, which belongs to the constructional engineering structure type. The limitation of the longitudinal reinforcement of a beam or a wall is avoided, the end part of the reinforcement of the welding wire-mesh reinforcement on the floorslab bottom is upwards bent to be anchored into the support, the welding wire-mesh reinforcement on the reinforced concrete floorslab bottom can be conveniently put to the proper position, so that the wire-mesh reinforcement is integrally used in one piece of plate, the later-stage supplementing and binding workload can be cancelled or reduced, the use amount of the reinforcement is saved, the floorslab wire-mesh reinforcement is conveniently applied in the engineering, and the commercial reinforcement is accelerated to popularize so as to achieve the effect on shortening the work period and lowering the engineering construction cost.

Description

The floor slab bottoms welded steel fabric anchors into the method for bearing

Technical field

The present invention relates to the building engineering structure class; The reinforcement structure that particularly relates to reinforced concrete floor; Especially refer to in-situ reinforced concrete slab bottom reinforcement bars welded mesh is anchored into the improvement of bearing method; Can make things convenient for floor slab bottoms welded steel fabric placed in position, can cancel or reduce the later stage and replenish the colligation workload, the floor slab bottoms welded steel fabric of saving amount of reinforcement anchors into the method for bearing.

Background technology

At present; The method that the reinforced concrete floor reinforcing bar anchors into bearing is the straight bearing that stretches into of bottom reinforcement bars, sees " Code for design of concrete structures " (GB50010-2010) 9.1.4 bar and " whole method for expressing cartographic convention of concrete structure construction plan and constructional detail " (11G101-1) the 92nd page.The problem that this method exists is; When bottom reinforcement bars adopts the full wafer welded steel fabric; The placement of welded steel fabric can receive the restriction of longitudinal reinforcement present position in bearing place beam or the wall; Welded steel fabric can't straightly stretch into bearing; Welded steel fabric can't be used by full wafer in a floor, the mode that can only take to block overlap joint or set up a diffusing reinforcing bar, way is seen " welded steel fabric concrete structure tecnical regulations " (JGJ 114-2003) 5.1.11 bar and " welded steel fabric concrete floor and shear wall constructional detail " (04SG309).

The problem of above-mentioned existence needs further to improve.

Summary of the invention

The present invention is directed to when the reinforced concrete floor bottom reinforcement bars adopts the full wafer welded steel fabric; The placement of welded steel fabric can receive the restriction of longitudinal reinforcement present position in bearing place beam or the wall; Welded steel fabric can't straightly stretch into the deficiency of bearing; Take after floor slab bottoms welded steel fabric end reinforced upwards having been bent, to anchor into the method for bearing, make welded steel fabric can stretch into bearing near support position.

Technical scheme of the present invention is: avoid the restriction of longitudinal reinforcement in beam or the wall; Anchor into bearing after reinforced concrete floor bottom reinforcement bars welded mesh end reinforced upwards bent, can make things convenient for reinforced concrete floor bottom reinforcement bars welded mesh placed in position, realize that welded steel fabric full wafer in a plate uses; Can cancel or reduce the later stage and replenish the colligation workload; Save amount of reinforcement, make things convenient for the floor bar welded mesh, promote the popularization of commercialization reinforcing bar in application in engineering; Reach the effect of reduction of erection time, reduction engineering construction cost, the method that floor slab bottoms welded steel fabric of the present invention anchors into bearing is:

A, the end reinforced of reinforced concrete floor bottom reinforcement bars welded mesh upwards bent;

B, reinforcing bar have been bent the inflection point and have been adjusted according to the needs of its structure design to the size of the distance at bearing edge;

C, the every end reinforced welded mesh of having bent of floor slab bottoms can adopt the full wafer welded steel fabric, also can adopt the burst welded steel fabric;

Artificial having bent or mechanical bending adopted in having bent of d, reinforcing bar.

Wherein, reinforcing bar is the listed any kind reinforcing bar of existing Code for design of concrete structures.

The present invention can make things convenient for reinforced concrete floor bottom reinforcement bars welded mesh placed in position; Realize that welded steel fabric full wafer in a plate uses; Can cancel or reduce the later stage and replenish the colligation workload, save amount of reinforcement, make things convenient for the floor bar welded mesh in application in engineering; Promote the popularization of commercialization reinforcing bar, reach the reduction of erection time, save steel, reduce the artificial effect of measuring, reducing the engineering construction cost.

Description of drawings

Fig. 1 for existing floor plate at the bottom of reinforcing bar anchor into the method front view of bearing.

Fig. 2 anchors into the method vertical view of bearing for existing floor bar welded mesh.

Fig. 3 anchors into the method sketch map of bearing for floor slab bottoms welded steel fabric of the present invention.

The figure number implication: 1. bearing, 2. the long span reinforcing bar, 3. loose a reinforcing bar, 4. another long span reinforcing bar, 4a. bend the long span reinforcing bar, have 5. shortly striden reinforcing bar, 6. another short reinforcing bar, 6a. of striding has been bent and located that weak point is striden reinforcing bar, 7. portion has been bent in the welded steel fabric end.

The specific embodiment

Shown in accompanying drawing 1 and accompanying drawing 2; For reinforcing bar at the bottom of the existing floor plate anchors into the method sketch map of bearing; As can be seen from the figure; Stride reinforcing bar 5 and the short reinforcing bar 6 of striding when adopting the full wafer welded steel fabrics when bottom long span reinforcing bar 2 and long span reinforcing bar 4 and short, the placement of welded steel fabric can receive the restriction of longitudinal reinforcement present position in beam or the wall place bearing 1, and welded steel fabric can't straightly stretch into beam or the bearing 1 of portion has been bent in wall welded steel fabric end; Welded steel fabric can't be used by full wafer in a floor, can only take the mode of blocking overlap joint or setting up a reinforcing bar 3 that looses.

Shown in accompanying drawing 3; Be employed near bearing 1 position the end reinforced of floor slab bottoms welded steel fabric upwards bent its this bottom long span reinforcing bar 4a; Become by having bent the welded steel fabric end that the long span reinforcing bar constitutes and bent portion 7 together with having bent the short reinforcing bar 6a that strides in place; After anchor into the method for bearing, make welded steel fabric can stretch into the bearing 1 of beam or wall.
