Abstract
The invention discloses a chiseling-free device for a concrete splicing interface and a construction method for the chiseling-free device, and belongs to the technical field of concrete construction. The problem of inconvenience for chiseling under the conditions of a greater height and a narrower operating space is solved. The device comprises a reinforcement frame, a thin plate sleeved on the front end face of the reinforcement frame and templates positioned on the two lateral surfaces of the reinforcement frame, wherein L-shaped angle steel is fixedly arranged at one end of each template; a plurality of meshes are distributed in the thin plate; each through hole is sleeved on the end part of a corresponding reinforcement. According to the device, the meshes are distributed in the thin plate, the through holes in the two sides of the thin plate are sleeved on the end parts of the reinforcements, the meshes in the thin plate are small holes before concrete is poured, and are squeezed by the concrete to be enlarged when the concrete is poured, a small part of the concrete is exposed from the thin plate across the meshes to form concavo-convex shapes, the concrete on the surface of the thin plate is concave-convex after the templates are disassembled, and surface chiseling work can be finished during segmental pouring.
Description
Technical field

Background technology
Concrete, as composite material commonly used, is widely used.To length, height during much larger than the works concreting of width, in order to improve the restriction of pouring quality and current conditions, need to carry out segmentation to works builds, the quality of segmentation pouring quality depends on the bond quality at joint face place to a great extent, in order to improve pouring quality, the dabbing technique that is absolutely necessary.
CN101054854A discloses a kind of job practices of quick roughening of concrete, the processing step of the method is: adopt interfacial agents brushing end-blocking template, the brushing thickness of interfacial agents is 0.1mm-0.5mm, then carry out form removal, remove again the end-blocking template, penetrate the concrete that is coated with interfacial agents one side with high pressure water flushing, expose stone, form fine and close, even and hackly roughening concrete surface.Yet, for situation highly higher, that operating space is narrower, dabbing is still more complicated.
Summary of the invention
In order to solve above-mentioned problems of the prior art, the present invention proposes a kind of concrete splicing interface and exempt from dabbing device and job practices thereof, can save the operation of segmentation surface dabbing while building.
One of task of the present invention is to provide a kind of concrete splicing interface to exempt from the dabbing device, and its technical scheme comprises:
The dabbing device is exempted from a kind of concrete splicing interface, comprise reinforced frame and be nested with the thin plate at the reinforced frame front end face, the left and right sides symmetry of described thin plate offers several through holes, described through hole in the vertical direction is straight line, be distributed with several meshes on described thin plate, described several through holes all are nested with the end at reinforcing bar; Described device also comprises the template that is positioned at the reinforced frame left and right side, the size of described template and the left and right side of reinforced frame are complementary, one end of described template is installed with the L-type angle steel, one side of described L-type angle steel is provided with several grooves along horizontal vertical in L-type angle steel direction, described groove for end reinforced by and reinforcing bar is fixed, described thin plate fits tightly in described L-type angle steel inboard.
Above-mentioned groove ends is V-shaped, and bottom is rectangle, and the width of rectangle equals bar diameter, and length is greater than the reinforcing bar radius, so that reinforcing bar is well fixed.
Above-mentioned template surface is provided with several square grooves, and the purpose that square groove is set is to alleviate template weight, strengthens template strength.
Two of task of the present invention is to provide the job practices of said apparatus, and the method comprises:
Step 1: at first reinforced frame is tied up, after reinforced frame has been tied up, the through hole of thin plate is nested with on the reinforcing bar of reinforced frame end;
Step 2: the groove of L-type angle steel is nested with on the reinforcing bar of above-mentioned reinforced frame end, and L-type angle steel inner surface is close to the external surface of thin plate;
Step 3: start to carry out concreting, during concreting, concrete extruding makes mesh become large, and the fraction concrete is crossed the exposed roughness that is outside thin plate of mesh, after concreting completes, and stripping.
The useful technique effect that the present invention brings:
The present invention proposes a kind of concrete splicing interface and exempt from dabbing device and job practices thereof, owing to being distributed with several meshes on thin plate, the through hole of thin plate both sides is nested with the end at reinforcing bar, and the mesh before concreting on thin plate is aperture, when concreting, concrete extruding makes mesh become large, it is exposed outside thin plate that the fraction concrete is crossed mesh, is roughness, after form removable, the thin sheet surface concrete is uneven, can avoid surface dabbing when segmentation is built.The present invention has simple in structure, economical reliable, is particularly useful for long, farsighted much larger than thick " wall " shape works.
