Abstract
The invention discloses a cement concrete expansion joint structure with large area ground; the structure comprises a cushion layer (1), concrete plates (2-1, 2-2 and 2-3), main expansion joints (3-1 and 3-2) and a secondary expansion joint (4), wherein the main expansion joints (3-1 and 3-2) are arranged among the concrete plates (2-1, 2-2 and 2-3); the secondary expansion joint (4) is arranged on the concrete plate (2-3); a 'comb-teeth-shaped' cross section is formed by the concrete plate (2-3) and the secondary expansion joint (4); extruded plates (5-1 and 5-2), a flexible filler and a flexible sealing material are filled in the main expansion joints (3-1 and 3-2); and the flexible filler and the flexible sealing material are also filled in the secondary expansion joint (4). The cement concrete expansion joint structure effectively eliminates the destructive power of temperature effect for the ground concrete, and the set widths of the expansion joints are very narrow, so that the joint hole concrete exposed corners can be better protected, the quantity of the sealing material in the joints can be reduced, and good economical efficiency can be achieved.
Description
Technical field
The present invention relates to the cement concrete constructions expansion joint structure, refer more particularly to cement concrete expansion joint structure and the implementation method thereof on large tracts of land ground.
Background technology
Along with the application of cement concrete in large tracts of land ground such as industrial premises, auditorium, exhibition club and pavement engineering, temperature action becomes outstanding to the influence of expanding with heat and contract with cold of cement concrete, regulation by existing " building floor engineering construction quality standards of acceptance " GB50209-2010, reply large tracts of land cement concrete ground arranges the shrinkage joint, but actual engineering construction remains in some problems, causes the common quality defect of ground failure.
Current specifications requires to stay the wide 20mm of reaching in the shrinkage joint of establishing, and there is obvious defects in such width, and on the one hand, filler quantity is more in the seam; On the other hand, the instrument dolly of transportation goods in the factory, because the wheel footpath is less, the external corner of easy clashing and breaking sealing both sides, thus cause cement concrete ground to be damaged along these seam both sides.
Implement at existing shrinkage joint, directly adopts the technology of " building back joint-cutting earlier " usually, in work progress, the flexible seaming and cutting of ubiquity namely can not disconnect adjacent two plates fully less than the phenomenon at the end, cause being easy under the temperature action produce the problem of destruction.

The implementation method of the cement concrete expansion joint structure on described large tracts of land ground is characterized in that: may further comprise the steps:
Step 1: the bed course of laying, ground grading;
Step 2: template is set, and the template of bottom 2/3 thickness range tilts 4 °～6 ° to the inside, and the template in 1/3 thickness range of top vertically arranges the concreting plate; Concrete plate solidifies the back form removal, adopts cutting machine that its edge is cut directly; Paste extruded sheet at the slit of the bottom of concrete plate 2/3 thickness range sidewall;
Step 3: concreting plate; The water seasoning concrete plate adopts cutting machine to cut out slit and time shrinkage joint of top, main shrinkage joint 1/3 thickness range successively;
Step 4: the employing dust catcher is eliminated the building waste in 1/3 slit, top, main shrinkage joint and time shrinkage joint, fills out embedding flexible filler and flexible sealing material then in the shrinkage joint successively, namely finishes.
Compared with prior art, the present invention has the following advantages:
1. structure of the present invention in the concreting stage, just is separated from position, main shrinkage joint fully, has avoided the not thorough hidden danger of quality that causes of joint-cutting.
2. the concrete lower part of building earlier tilts 4 °～6 ° in advance to the inside, be beneficial in the work progress quality assurance to main shrinkage joint, even the mould phenomenon that expands takes place in some part, also can guarantee that the adjacent concrete plate has the main shrinkage joint of perforation to exist along vertical direction, reduces the risk of concrete intensification expansion squeeze and destroy.
3. in position, main shrinkage joint extruded sheet is set, it isolates dependable performance, strong, easy to operate, the good economy performance of absorption concrete plate deformation ability of adjacent plate.
4. the width at main shrinkage joint and time shrinkage joint is all little in the concrete plate, has eliminated the factory in the instrument dolly because of the wheel risk of less clashing and breaking sealing both sides external corner directly.Simultaneously, the airtight and watertight padding quantity in the shrinkage joint significantly reduces, and has excellent economy.
