[0002] Wet joint refers to prestressed concrete beam body block prefabrication, when adopting cantilever assembly into large span continuous beam, the beam body adopts cast-in-situ concrete to connect the beam block into whole joint. Bridge wet joint is used for connecting T beam and box girder piece. Bridge wet joint is located in the transverse connection of T beam box girder, and it is usually adopted that hoop circle is in the middle and longitudinal reinforcement is passed to make the bridge deck form whole, then the same mark concrete as the beam body is poured.

[0003] In the traditional bridge construction, the formwork installation of wet joint usually adopts the way of block hoisting, and the efficiency is low and the wet joint is easy to leak. Therefore, it is urgent to design a bridge wet joint formwork structure with high construction efficiency and not easy to leak. UTILITY MODEL CONTENT

[0005] A bridge wet joint formwork structure, which comprises a formwork, the formwork is installed at the bottom of the wet joint between two split girders, the upper surface of the formwork is fixedly provided with four water stop screws, the four water stop screws are distributed in a rectangular shape, the top of the two split girders is horizontally provided with two groups of lifting poles, each group of lifting poles comprises two horizontal lifting poles, the upper part of the four water stop screws is respectively provided with a mountain-shaped clamp, the water stop screw is threadedly connected with a limiting nut for limiting the mountain-shaped clamp at the top end of the mountain-shaped clamp, and the mountain-shaped clamp is arranged on the corresponding group of lifting poles.

[0006] Further, the bottom end of the water stop screw penetrates the formwork and is fixedly connected with a water stop plate, and the water stop screw and the formwork are threadedly connected.

[0007] Further, the lifting pole is a reinforcing steel bar, and the two ends of the lifting pole are arranged on the top of the two split girders.

[0008] Further, a square fender is arranged between the lifting pole and the top of the split girder.

[0009] Further, the upper surface of the formwork is fixedly provided with a lifting ring, and the lifting ring is a steel wire rope with both ends fixed on the formwork.

[0010] Compared with the prior art, the utility model has the advantages that:

[0011] The utility model discloses use whole template as wet joint bottom template, thereby need not splicing, not only improved construction efficiency, but also not easy to have the phenomenon of leaking paste. BRIEF DESCRIPTION OF DRAWINGS

[0016] The technical scheme in the embodiments of the utility model will be apparently and completely described below with reference to the drawings in the embodiments of the utility model, and apparently, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without making creative efforts belong to the range of protection of the utility model.

[0017] REFERENCE Figs. 1-3 , a kind of bridge wet joint template structure, including template 1, template 1 is installed in the bottom of wet joint between two split beams, and its upper surface is in contact with the bottom surface of split beam, the upper surface of template 1 is fixedly installed with four water stop screws 2, four water stop screws 2 are distributed in rectangle, the top of two split beams is placed with two groups of mutually horizontal sling stick, each group of sling stick includes two mutually horizontal sling sticks 4, the upper part of four water stop screws 2 is respectively sleeved with mountain type card 5, water stop screw 2 is threadedly connected with the limiting nut 7 for limiting mountain type card 5 on the top end of mountain type card 5, mountain type card 5 is respectively erected on corresponding sling stick, so as to utilize sling stick 4, mountain type card 5 and water stop screw 2 to fix template 1.

[0018] In the embodiment, the bottom end of water stop screw 2 penetrates template 1 and is fixedly connected with water stop plate 6, so as to avoid leaking paste, water stop screw 2 is threadedly connected with template 1.

[0019] In the embodiment, sling stick 4 is reinforcing bar, and the two ends of sling stick 4 are placed on the top of two split beams respectively.

[0020] In the embodiment, square fender is arranged between sling stick 4 and the top of split beam, so as to avoid that sling stick 4 causes damage to split beam and improve the stability of sling stick 4.

[0021] In the embodiment, the upper surface of the template 1 is fixedly provided with a lifting ring 3, and the lifting ring 3 is a steel wire rope with both ends fixed on the template 1, so as to facilitate hoisting the template 1 to the wet joint.

[0022] The utility model uses the whole template as the wet joint bottom template, so that the template does not need to be spliced, which not only improves the construction efficiency, but also avoids the phenomenon of slurry leakage.

[0023] The above is only the preferred embodiment of the utility model, and does not limit the technical range of the utility model, so any slight modification, equivalent change and modification of the above embodiment according to the technical essence of the utility model still belong to the range of the technical scheme of the utility model.
