Abstract
The invention relates to a bracket-free and pull rod-free steel template device for an overhead cast-in-place concrete anti-collision wall. The steel template device comprises an inner template, an outer template, an outer mould section steel framework, a bottom opening connecting bolt and an inner mould supporting system, wherein a lower opening of the outer template is fixedly connected with the bottom of a box girder flange through the bottom opening connecting bolt, and an upper opening of the outer template is fixedly connected with the inner template through the outer mould section steel framework; the fractional lengths of the inner template and the outer template are 1-3 m; the inner mould supporting system is arranged between the inner template and the surface of a bridge. According to the steel template device, an outer mould is fixed by an inner mould, a pull screw rod is not arranged in the anti-collision wall, an individual supporting bracket is not arranged on the outer side of the anti-collision wall, and the inner and outer templates of a steel template form a whole body and a stable system. The steel template device is simple in structure, safe, reliable, convenient to mount and dismount, and low in resource input.
Description
Technical field
The present invention relates to a kind of steel form device of cast-in-situ concrete, especially a kind of non pull rod type steel form device for the crashproof wall of overhead cast-in-situ concrete.
Background technology
For the crashproof wall of the overhead cast-in-situ concrete mode fixed forms that adopt pre-buried Screw arbor with nut at both-ends within the walls or establish external bracing bracket more, after completing and building, also need preformed hole to repair or removal bracket, anti-collision wall outward appearance is had a certain impact, construction reliability is not high, and efficiency of construction is low, measure has high input.
Summary of the invention
The present invention be to provide a kind of for the crashproof wall of overhead cast-in-situ concrete without bracket non pull rod type steel form device, this installs simple structure, makes precision high, peace easy accessibility.
For achieving the above object, technical scheme of the present invention is: a kind of for the crashproof wall of overhead cast-in-situ concrete without bracket non pull rod type steel form device, comprise inner formword, exterior sheathing, external model steel frame, end mouth connecting bolt, internal mold support system, be characterized in: exterior sheathing end opening is fixedly connected with by end mouth connecting bolt and case beam wing plate bottom, suitable for readingly by external model steel frame, be fixedly connected with inner formword.
Inner formword and exterior sheathing section length are 1 ~ 3m.Between inner formword and bridge floor, lay internal mold support system.
Useful achievement of the present invention is: utilize fixedly external mold of internal mold, do not establish Screw arbor with nut at both-ends in anti-collision wall, independent Support bracket is not also established in outside simultaneously, and steel form inner and outer template forms integral body, has stabilising system of one's own.The present invention is simple in structure, safe and reliable, peace easy accessibility, and input can economize on resources.
Accompanying drawing explanation
Fig. 1 is structure side view of the present invention.
the specific embodiment
Below in conjunction with instantiation, further set forth the embodiment of patent of the present invention.Should be understood that these examples are only not used in the scope of restriction patent of the present invention for patent of the present invention is described.In addition should be understood that those skilled in the art can make various changes or modifications the present invention after having read the content of patent instruction of the present invention, these equivalent form of values fall within the application's appended claims limited range equally.
As shown in Figure 1, of the present invention for the crashproof wall of overhead cast-in-situ concrete without bracket non pull rod type steel form device, comprise inner formword 1, exterior sheathing 2, external model steel frame 3, end mouth connecting bolt 4 and internal mold support system 5.
The fixed system of inner formword 1 of the present invention, exterior sheathing 2 for establishing one's own system, in the airly hits the pre-buried connection measure such as Screw arbor with nut at both-ends and steel band within the walls, simultaneously also without the external bracing measures such as bracket of encorbelmenting.
Concrete operation method of the present invention:
1) while constructing, first at bridge floor, arrange the fulcrum of internal mold support system 5, then inner formword 1 is installed.
2) exterior sheathing 2 is installed, exterior sheathing 2 end openings utilize end mouth connecting bolt 4 fixing with case beam wing plate bottom, and the external model steel frame 3 that utilizes suitable for reading is connected and fixed with inner formword 1.
3) template system carries out concreting after fixedly completing.
4) after completing and building, first remove end mouth connecting bolt 4, then remove alignment pin and connecting bolt on external model steel frame 3, exterior sheathing 2 is removed and connected with inner formword 1.
5), according to the first exterior sheathing 2 orderly release template of inner formword 1 again, be transferred to next work sections.
