Disclosure of Invention

The utility model aims at overcoming the above-mentioned not enough and providing a simple structure, installation and demolish safe quick public special die block of iron bridge floor wet joint construction of striding.

The utility model discloses a template, a plurality of parallel arrangement are at the first square timber of template bottom, a plurality of parallel arrangement at the second square timber at case roof beam top, template both ends symmetry sets up two holes two, be provided with first PVC pipe in the hole two respectively, wear to be equipped with the second iron wire in the first PVC pipe, the one end of second iron wire is passed hole two with the first square timber of template bottom is connected, the other end and the gentle rope of second iron wire are connected, be provided with a plurality of holes one in the template, the template through first iron wire with the second square timber is connected, first iron wire overcoat is equipped with third PVC pipe.

And the first iron wire penetrates through the first hole to connect and fix the first square wood, the second square wood and the template.

And a plurality of second PVC pipes are symmetrically arranged on the template.

The first PVC pipe, the second PVC pipe and the third PVC pipe are PVC pipes with different diameters.

The width of the template is larger than that of the wet joint, and the widths of the first square timber and the second square timber are larger than that of the template.

The utility model has the advantages that:

firstly, the structure is simple, the installation and the removal are safe and quick, and the wet joint template can be safely and quickly removed under the condition of not contacting with contact network equipment, so that the operation difficulty is reduced, and the construction efficiency is improved;

second, the utility model discloses well all wet seam templates prop up to tear open and concreting all go on in blockading the point, and the security is high.

Detailed Description

The present invention will be further described with reference to the accompanying drawings and examples.

Referring to fig. 1-5, the utility model discloses a template 1, a plurality of parallel arrangement are at first square timber 2 of template 1 bottom, a plurality of parallel arrangement at the second square timber 3 at 15 tops of case roof beam, 1 both ends symmetry of template sets up two hole two 6, all be provided with first PVC pipe 8 in the hole two 6, wear to be equipped with second iron wire 11 in the first PVC pipe 8, the one end of second iron wire 11 is passed hole two 6 with the first square timber 2 of template 1 bottom is connected, the other end and the flexible rope 12 of second iron wire 11 are connected, be provided with a plurality of holes 4 on the template 1, template 1 through first iron wire 7 with second square timber 3 is connected, first iron wire 7 overcoat is equipped with third PVC pipe 10. And the first iron wire 7 penetrates through the first hole 4 to fixedly connect the first square wood 2, the second square wood 3 and the template 1. And a plurality of second PVC pipes 9 are symmetrically arranged on the template 1. The first PVC pipe 8, the second PVC pipe 9 and the third PVC pipe 10 are PVC pipes with different diameters. The width of the formwork 1 is larger than that of the wet joint 5, and the widths of the first square timber 2 and the second square timber 3 are both larger than that of the formwork 1.

The utility model discloses a theory of operation is: firstly, a template 1 is manufactured, a first hole 4 and a second hole 6 are drilled in the template 1, a first iron wire 7 is used for binding the template 1 and a first batten 2 together through the first hole 4, a second iron wire 11 is used for binding one end of the second hole 6 on the batten 3, and the other end of the second hole 8 is used for binding a flexible rope 12; the two ends of the combined template 1 are suspended by flexible ropes 12 and are placed between a contact net 13 and a prefabricated box girder 15 from a position of a wet joint 5 far away from the contact net 13, the combined template stops moving to the position right above the contact net 13 along the direction of the box girder 15, and a first iron wire 7 penetrates into a third PVC pipe 10 to connect and fix a first batten 2, a second batten 3 and the template 1;
