Technical field
The utility model relates to a kind of arch culvert construction formwork, a kind of template system that is applied in highway, the construction of railway arch culvert of more specifically saying so.
Background technology
At present, in the construction to railway, highway arch culvert, be mostly to set up steel pipe support, utilize bamboo offset plate assembling combination arch culvert template, there is following problem in this job practices in reality:
1, sets up that steel pipe support construction is loaded down with trivial details, speed is slow.
2, bamboo offset plate material is the not reproducible material that utilizes, and stock utilization is low, cost of idleness, and social benefit is low.
3, bamboo offset plate material makes the out-of-flatness of concreting molded surface, influences attractive in appearance.
The utility model content
The utility model is can satisfy various road and rail arch culvert constructions, can effectively improve efficiency of construction for avoiding the deficiency of above-mentioned prior art, providing a kind of, and can reduce the semi-automatic arch culvert construction formwork that material expends.
The utility model technical solution problem adopts following technical scheme:
The design feature of the semi-automatic arch culvert construction formwork of the utility model is:
One door shaped stent longitudinally is set, and parallel longitudinal is provided with the two support rollers of being disbursed from the cost and expenses in frame upper edge, the top of said door shaped stent;
Being two groups of backform truss that are symmetrical set is respectively the triangular structure that constitutes with chord member and diagonal brace, and said chord member is supported by jacking cylinder on the top frame that is fixedly installed on door shaped stent and roller; Symmetrical two groups of backform truss are to get in touch between diagonal brace with the leading screw of adjustable-length;
Backform by about two pitch circles arch section hinged at the middle part by steel pin, form hinge structure; Two pitch circles arch section is fixedly welded on respectively on the backform truss of a corresponding side about said backform;
A pair of side form is articulated in the two ends of backform respectively, and locatees with the side frame support of door shaped stent;
The segmentation of arch form external mold is provided with, and by the periphery of pull bar positioning supports at the arch form internal mold that constitutes by backform and side form.
The design feature of the semi-automatic arch culvert construction formwork of the utility model also is:
Said door shaped stent is processed by shaped steel, adopts removable bolt to connect between each rod member of formation door shaped stent.
The length setting of vertically pressing arch culvert of said door shaped stent.
Fixing welding one vertical draw runner on the chord member of said backform truss, the chord member of said backform truss is to be bearing on the roller with said vertical draw runner.
Compared with present technology, the utility model beneficial effect is embodied in:
1, the utility model as long as can realize formwork through the fit adjustment of jacking cylinder and leading screw, utilizes door shaped stent to move after once accomplishing assembly unit, realizes semi-automatic construction formwork, can greatly improve efficiency of construction;
2, the utility model can be reused, and does not cause raw-material expending.
3, the utility model adopts steel form to make the concrete surface smooth, improves presentation quality.
Description of drawings
Fig. 1 is the utility model cross-sectional configuration sketch map;
Fig. 2 is the utility model vertical structure sketch map;
Label among the figure: 1 leading screw, 2 backform truss, 3 walking rollers, 4 vertical draw runners, 5 jacking cylinders, 6 steel pins, 7 door shaped stents, 8 backforms, 9 side forms, 10 external molds, 11 pull bars.
The specific embodiment
Referring to Fig. 1, Fig. 2, in the present embodiment, door shaped stent 7 is set longitudinally, vertically be the length direction of arch culvert, in frame upper edge, the top of door shaped stent 7 parallel longitudinal be provided with two be disbursed from the cost and expenses the support roller 3; Being two groups of backform truss 2 that are symmetrical set is respectively the triangular structure that constitutes with chord member and diagonal brace, and chord member is supported by jacking cylinder on the top frame that is fixedly installed on door shaped stent 75 and roller 3; Symmetrical two groups of backform truss 2 are to get in touch between diagonal brace with the leading screw 1 of adjustable-length, regulate the length of leading screw 1, can regulate the degree that backform 8 launches;
Backform 8 by about two pitch circles arch section hinged at the middle part by steel pin 6, form hinge structure; Two pitch circles arch section is fixedly welded on respectively on the backform truss 2 of a corresponding side about backform 8; A pair of side form 9 is articulated in the two ends of backform 8 respectively, and locatees with the side frame support of door shaped stent 7; The 10 segmentation settings of arch form external mold, and by the periphery of pull bar 11 positioning supports at the arch form internal mold that constitutes by backform 8 and side form 9.
In the practical implementation, door shaped stent 7 is processed by shaped steel, constitutes between each rod member of door shaped stent 7 to adopt removable bolt to connect; The longitudinal length of door shaped stent 7 is pressed the length setting of arch culvert.For fear of wearing and tearing to backform truss 2, can on the chord member of backform truss 2, fix welding one vertical draw runner 4, the chord member of backform truss 2 is to be bearing on the roller 3 with vertical draw runner 4, vertically draw runner 4 is a steel plate.
Work progress:
1, hardened ground meets the demands the ground loading ability, setting-out arch culvert center line;
2, set up door shaped stent 7 in the arch culvert bottom by arch culvert length; Assembly unit backform 8 above door shaped stent 7 through the elevation of jacking cylinder 5 adjustment backforms 8, and guarantees that the bilateral symmetry structure is on the same horizon; Adjust the expansion degree of backform 8 then through leading screw 1, the location of accomplishing backform 8;
3, side form 9 and external mold 10 are installed, and are fixed and support the installation of completion template with pull bar 11;
4, concreting, treat concrete formation after, at first remove pull bar 11; Remove side form 9 then, shrink jacking cylinder 5 and leading screw 1 afterwards, backform 8 and concrete are broken away from; Vertically draw runner drops on for 4 times on the roller 3 simultaneously; Through electric block backform 8 is longitudinally moved forward at door shaped stent 7, backform 8 is hauled out built the arch culvert section of completion, and get into next arch culvert construction section.
