Abstract
The present invention discloses a reinforced concrete crack resisting wall. Prestress reinforced concrete sheets are set on one or both sides of the wall and reinforced concrete is placed between the sheets. The construction process includes: (1) placing cage of reinforcement on the foot, (2) fixing the prestress reinforced concrete sheets or templates on both sides of the cage, (3) placing concrete between sheets or sheet and template, and (4) removing the templates. Via setting prestress reinforced concrete sheets on one or both sides of the wall, the stress caused by load or temperature contraction is resisted by the sheets and recently placed concrete together. The prestress sheets have high crack resistance reducing the width of cracks and the distance between cracks effectively. In construction, the combining places up and down are staggered to avoid continuous cracks and improve crack resistance and leakage resistance. The invention also reduces the consumption of the reinforcing steel bar cutting down the cost.
Description
Technical field:
The present invention relates to the realm of building construction, specifically refer to a kind of crack resistant steel concrete wall and job practices thereof.
Background technology:
House subterranean layer exterior wall adopts reinforced concrete structure mostly at present, because concrete tensile strength is low, under load action and temperature shrinkage stress effect, concrete easily produces temperature contraction distortion, wall crazing, influence the normal use and the leakage performance in house, existing concrete structure cracking resistance technology commonly used is to increase quantity of reinforcement and adopt prestressed concrete.Increase the width that quantity of reinforcement can strengthen the concrete structure anti-crack ability and reduce the crack, but the increase of amount of reinforcement improves cost, cost; The prestressed concrete effect of prestressed is good, but the site operation difficulty is big.
Summary of the invention:
The object of the present invention is to provide a kind of body of wall not easy to crack, cost, the crack resistant steel concrete wall that cost is low.The present invention also aims to provide a kind of job practices of making this anti-cracking wall.
The object of the present invention is achieved like this, this crack resistant steel concrete wall comprises body of wall, in the body of wall one or both sides prestressed reinforced concrete thin plate is set, and builds steel concrete between the biside plate.
For making above-mentioned anti-cracking wall, job practices of the present invention comprises the steps: (1) reinforcing cage on footing earlier; (2) then prestressed reinforced concrete thin plate or template are fixed on the reinforcing cage both sides; (3) at concreting between the thin plate of both sides or between thin plate and the template; (4) remove template.
Owing to the prestressed reinforced concrete thin plate is set in the body of wall one or both sides, be subjected to load action and temperature shrinkage stress is done the time spent, prestressed reinforced concrete thin plate and cast-in-placely build the effect that concrete is resisted stress jointly, the prestressed reinforced concrete thin plate has higher anti-crack ability, can effectively reduce the width of distress in concrete and the spacing in crack, in the construction, the place misplaces up and down with thin plate splicing, can avoid the crack of splicing place up/down perforation, improve the cracking resistance and the leakage performance of body of wall.The thin plate amount of reinforcement is little, and cost, cost are reduced.
The present invention is further detailed explanation below in conjunction with drawings and Examples.
Description of drawings:
Fig. 1 cracking resistance body of wall one side is provided with the prestressing force thin plate, and opposite side is provided with the formwork structure schematic diagram
Fig. 2 cracking resistance body of wall both sides are provided with prestressed reinforced concrete thin-slab structure schematic diagram
Fig. 3 prestressed reinforced concrete thin plate stereogram
Fig. 4 prestressed reinforced concrete thin plate stereogram with ribbing
The specific embodiment:
With reference to figure 1, Fig. 2, Fig. 3, Fig. 4, this crack resistant steel concrete wall comprises body of wall, in body of wall one side prestressed reinforced concrete thin plate 4 is set, and opposite side is provided with template 1, puts reinforcing cage 2, concreting 3 between thin plate 4 and the template 1; Or prestressed reinforced concrete thin plate 4 is set in body of wall 4 both sides, and put reinforcing cage 2 between the both sides thin plate 4, concreting 3 forms anti-cracking wall, and prestressed reinforcement 7 is arranged in the thin plate 4, and ribs 8 has strengthened the active force of thin plate 4 with concrete 3.
For making above-mentioned anti-cracking wall, job practices of the present invention comprises the steps: (1) reinforcing cage 2 on footing earlier; (2) then prestressed reinforced concrete thin plate 4 or template 1 can be fixed on reinforcing cage 2 both sides with bolt 5; (3) at concreting 3 between the both sides thin plate 4 or between thin plate 4 and the template 1; (4) remove template 1.
Claims (2)
1, a kind of crack resistant steel concrete wall comprises body of wall, it is characterized in that: the body of wall one or both sides are provided with the prestressed reinforced concrete thin plate, build steel concrete between the biside plate.
2, a kind of job practices of making the described anti-cracking wall of claim 1 is characterized in that: comprise the steps: (1) reinforcing cage on footing earlier; (2) then prestressed reinforced concrete thin plate or template are fixed on the reinforcing cage both sides; (3) at concreting between the thin plate of both sides or between thin plate and the template; (4) remove template.
