Abstract
A method for reinforcing web members of a reinforced concrete truss includes: cleaning damaged concrete of the web members of the reinforced concrete truss, removing rust on rusted reinforcing bars and applying anti-rust agent; sleeving a PVC (polyvinyl chloride) pipe with an elongated slit on each of the web members of the reinforced concrete truss and plugging the slit by a wooden plate; pouring resin concrete into the PVC pipes, hooping the PVC pipes with carbon fiber fabrics or steel plate hoops so that the resin concrete can be spilled and the purpose that the resin concrete can be extruded to be compact automatically is achieved; and removing the wooden plates at the slits after the resin concrete is solidified. The method for reinforcing the web members of the reinforced concrete truss by the resin concrete filled in the PVC pipes is simple, convenient, efficient and capable of repairing and reinforcing rusted reinforcing bars and seriously-damaged concrete of the web members of the reinforced concrete truss.
Description
Technical field
The present invention relates to a kind of reinforced steel concrete truss web method, be particularly useful for the reinforcing under web member concrete badly broken, the corrosion of steel bar situation in the reinforced concrete truss under the coal mine ground industrial environment.
Background technology
Because the special ground industrial environmental influence in colliery, reinforced concrete truss web member in the colliery causes the concrete badly broken because the reinforcing bar rust expands, and then the corrosion of steel bar faster, has a strong impact on industrial safety.Reinforcing for this class A of geometric unitA generally is earlier reinforcing bar to be eliminated rust, and repair the concrete of badly broken the back, safeguards accordingly at last.But because the sectional area of web member is little, be inconvenient to utilize the mode of traditional formwork to carry out the concrete reparation, promptly use the formwork way of small size to carry out the concrete reparation, can not guarantee the density of newly placed concrete.
Summary of the invention
The purpose of this invention is to provide a kind of simple to operate, reinforced steel concrete truss web method that repairing and reinforcement is good.
Reinforced steel concrete truss web method of the present invention comprises the steps:
A, the damaged concrete of reinforced concrete truss web member is cleared up, and to the reinforcing bar of corrosion eliminate rust, the brushing corrosion inhibitor;
B, suit has rimal pvc pipe on the reinforced concrete truss web member, and with plank opening part is carried out shutoff;
C, in pvc pipe, water resin concrete, with the pvc pipe banding, resin concrete is overflowed,, treat that resin concrete solidifies the plank of removing the opening part shutoff in the back and gets final product to reach the closely knit purpose of resin concrete self compaction with the hoop of carbon cloth or steel plate.
Beneficial effect: the present invention utilizes pvc pipe resin concrete reinforced concrete truss web simple, convenient, effective; Can guarantee the density of resin concrete; Reach the purpose of reinforcing, can effectively handle the reparation and the reinforcing of reinforced concrete truss web member concrete badly broken, corrosion of steel bar.
Description of drawings
Fig. 1 is a hoop pvc pipe resin concrete reinforced steel concrete truss web sketch map of the present invention;
Fig. 2 is the sectional drawing of Fig. 1,
Among the figure: 1-concrete truss web member; The 2-PVC pipe; The 3-hoop; The 4-resin concrete.
The specific embodiment
Below in conjunction with accompanying drawing one embodiment of the present of invention are done further to describe:
Reinforced steel concrete truss web method of the present invention: at first reinforced concrete truss web member 1 damaged concrete is cleared up; And to corrosion reinforcing bar wherein eliminate rust, the brushing corrosion inhibitor, suit has rimal pvc pipe 2 on concrete truss web member 1 afterwards, and with plank opening part is gone into to carry out temporary blocking; In pvc pipe, water resin concrete then; The hoop 3 that adopts CFRP (carbon cloth) or steel plate overflows resin concrete 4 compactings of pouring in the pvc pipe, to reach the closely knit purpose of resin concrete 4 self compactions pvc pipe 2 bandings; After treating that resin concrete 4 solidifies, the plank of removing the opening part temporary blocking gets final product.
Claims (1)
1. a reinforced steel concrete truss web method is characterized in that comprising the steps:
A, the damaged concrete of reinforced concrete truss web member is cleared up, and to the reinforcing bar of corrosion eliminate rust, the brushing corrosion inhibitor;
B, suit has rimal pvc pipe on the reinforced concrete truss web member, and with plank opening part is carried out shutoff;
C, in pvc pipe, water resin concrete, with the pvc pipe banding, resin concrete is overflowed,, treat that resin concrete solidifies the plank of removing the opening part shutoff in the back and gets final product to reach the closely knit purpose of resin concrete self compaction with the hoop of carbon cloth or steel plate.
