Utility model content
Technical problem to be solved in the utility model is to provide the core of a kind of structure In Reinforced Concrete Box Girder simple, with low cost.
For solving the problems of the technologies described above, the utility model provides a kind of core of In Reinforced Concrete Box Girder, comprises jack and the die body agreeing with In Reinforced Concrete Box Girder endoporus;
Die body comprises left template and right template, and right template and left form assembly inside form die cavity jointly;
Jack is vertically placed between left template and right template, on the epicoele wall that jack is supported on die cavity respectively and chamber, end wall.
After adopting such structure, the core of this In Reinforced Concrete Box Girder has simple, with low cost, the on-deformable advantage of structure, and achieve installation, remove achieve mechanization, improve efficiency of construction, guarantee the presentation quality of engineering.
In order to better understand technology contents of the present utility model, below say that the core of this In Reinforced Concrete Box Girder is referred to as this core.
Left template and the right template of this core are all made up of upper die and lower die, pass through hinge between upper die and lower die; After adopting such structure, make left template and right model sheetinstallat, remove operation more simply, conveniently.
The counterdie of the left template of this core and the counterdie of right template are provided with some demoulding assemblies, described demoulding assembly at least comprises demoulding nut and stripper bolt, demoulding nut is fixed on chamber, the end wall of die cavity, stripper bolt and demoulding nut screw connection, and respective corresponding counterdie bottom surface is run through in the lower end of stripper bolt; After adopting such structure, convenient In Reinforced Concrete Box Girder build shaping after, left template and right template depart from the inner hole wall of case beam.
The demoulding assembly of this core also comprises pressing plate, and pressing plate and stripper bolt lower end are fixed; After adopting such structure, the contact area of In Reinforced Concrete Box Girder inner hole wall after pressing plate can increase stripper bolt and be shaped, avoids causing damage to In Reinforced Concrete Box Girder inner hole wall after shaping.
Accompanying drawing explanation
Fig. 1 is the structural representation of existing In Reinforced Concrete Box Girder.
Fig. 2 is the structural representation of this core embodiment.
Fig. 3 is the A portion enlarged drawing of Fig. 2.
Fig. 4 is the using state figure of this core embodiment.
Detailed description of the invention
As shown in Figures 2 to 4
This core comprises jack 4 and agrees with the die body of In Reinforced Concrete Box Girder 1 endoporus 11;
Die body comprises left template 21 and right template 22, left template is identical with the structure of right template, all by patrix 21a, 22a and counterdie 21b, 22b is formed, patrix 21a, 22a and counterdie 21b, 22b is lamellar, patrix 21a, 22a and counterdie 21b, 90 ° of bendings are had in the middle part of 22b, the patrix 21a of left template 21 is hinged with the counterdie 21b of left template 21 by multiple first hinge 31, the pivot center of all first hinges 31 is all on same straight line, the patrix 22a of right template 22 is hinged with the counterdie 22b of right template 22 by multiple second hinge 32, the pivot center of all second hinges 32 is all on same straight line, right template 22 and left template 21 combine inner common formation die cavity 23.
Jack 4 is hydraulic jack 4, the cylinder body 42 of jack 4 is vertically placed on the counterdie 21b of left the template 21 and counterdie 22b of right template 22, hydraulic push rod 41 upper end of jack 4 is supported on the patrix 21a of left the template 21 and patrix 22a of right template 22, namely jack 4 is supported between the epicoele wall of die cavity 23 and chamber, end wall, and the first hinge 31 and the second hinge 32 are all in die cavity 23.
The counterdie 21b of left the template 21 and counterdie 22b of right template 22 is also provided with many group demoulding assemblies, described demoulding assembly comprises pressing plate 51, demoulding nut 52 and stripper bolt 53, demoulding nut 52 is fixed on chamber, the end wall of die cavity 23, stripper bolt 53 coordinates with demoulding nut 52, and the respective corresponding counterdie 21b of left the template 21 or counterdie 22b of right template 22 is run through in the lower end of stripper bolt 53, pressing plate 51 and stripper bolt 53 lower end are fixed.
Before pouring reinforcement concrete case beam 1, first fix plastotype template 6 outside In Reinforced Concrete Box Girder 1, then this core is fixed in plastotype template 6, because the length of this core is longer than plastotype template 6 length, so this core stretches out both sides before and after plastotype template 6;
First regulate stripper bolt 53 to the extreme higher position of demoulding assembly, regulate left template 21 and right template 22 more respectively, the counterdie 21b of left template 21 is contacted with the counterdie 22b of right template 22, start jack 4, the hydraulic push rod 41 of jack 4 is stretched height and is resisted against on left template 21 patrix 21a and right template 22 patrix 22a, the cross sectional shape of die cavity 23 is fixed, so far puts up this core, the operation of pouring reinforcement concrete case beam 1 can be carried out.
After In Reinforced Concrete Box Girder 1 is shaping, first the plastotype template 6 outside pouring reinforcement concrete case beam 1 is removed, restart jack 4, the hydraulic push rod 41 of jack 4 is shunk, the upper end of hydraulic push rod 41 departs from the patrix 21a of left the template 21 and patrix 22a of right template 22, the patrix 21a of left the template 21 and patrix 22a of right template 22 rotates along the axis of the first hinge 31 and the second hinge 32 respectively under self gravitation effect, the patrix 21a of left the template 21 and patrix 22a of right template 22 departs from In Reinforced Concrete Box Girder 1 endoporus 11, the stripper bolt 53 of demoulding assembly is regulated to move downward along the axis direction of stripper bolt 53 again, stripper bolt 53 is with dynamic pressure plate 51 to move down, the counterdie 21b of left the template 21 and counterdie 22b of right template 22 is driven to depart from In Reinforced Concrete Box Girder 1 endoporus 11, and then make endoporus 11 hole wall of this core integral reinforced concrete case beam 1, convenient dismounting.
Above-described is only a kind of embodiment of the present utility model; it should be pointed out that for the person of ordinary skill of the art, under the prerequisite not departing from the utility model principle; can also make some modification and improvement, these also should be considered as belonging to protection domain of the present utility model.
