By adopting the structure, when the bridge deck is widened in construction, the middle part of the transverse supporting pipe frame is positioned in the gap between the box girder and the bridge pier and supported on the bridge pier, so that the whole supporting structure can be guaranteed to have good stress strength, and the templates are supported on the two sides of the bridge deck through the longitudinal pipe frame, so that pouring construction can be facilitated.

Preferably, the method comprises the following steps: the longitudinal pipe support, the transverse support pipe support and the vertical support pipe support are all composed of at least two steel pipes. By adopting the structure, the strength of the supporting structure can be ensured.

Preferably, the method comprises the following steps: the horizontal support part is provided with a strip-shaped hole which penetrates through the horizontal support part along the length direction of the horizontal support part, and the steel pipe of the longitudinal pipe frame is arranged in the strip-shaped hole in a penetrating mode. Adopt above-mentioned structure to installation is convenient for.

Preferably, the method comprises the following steps: one end of the stopping part is provided with a positioning groove, the other end of the stopping part is provided with a connecting block matched with the positioning groove, and two adjacent groups of templates are fixedly connected through the connecting block and the positioning groove. By adopting the structure, all the templates on the same side can be fixed together conveniently.

Preferably, the method comprises the following steps: the connecting block is provided with via holes, and the positioning groove is provided with threaded holes capable of coinciding with the via holes. By adopting the structure, two adjacent groups of templates can be fixedly connected by adopting a bolt beating mode.

Compared with the prior art, the beneficial effects of the utility model are that:

1. when the construction is widened at the bridge floor, the middle part that transversely supports the pipe support is located the clearance department of box girder and pier to support on the pier, can guarantee that whole bearing structure has fine atress intensity, the template supports in the both sides of bridge floor through vertical pipe support, can conveniently pour into a mould the construction.

2. Structural design is reasonable, simple, builds the convenience, helps promoting the efficiency of construction that the bridge floor widened.

3. When the overpass is widened, the influence on traffic below the bridge and surrounding roads is small, and the method is particularly suitable for urban overpass widening projects.

Detailed Description

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

As shown in fig. 1 and 2, a bridge deck widening support structure comprises two sets of longitudinal support assemblies 1, each set of longitudinal support assembly 1 comprises a longitudinal pipe frame 1a and templates 1b sequentially arranged on the longitudinal pipe frame 1a, wherein the templates 1b are made of plastics, metals or woods, the templates 1b are integrally of an L-shaped structure and are provided with horizontal support portions 1b1 and stop portions 1b2 arranged at the outer ends of the horizontal support portions 1b1, strip-shaped holes 1b3 penetrating along the length direction of the horizontal support portions 1b1 are formed in the horizontal support portions 1b1, each longitudinal pipe frame 1a comprises two steel pipes arranged in parallel, and the two steel pipes penetrate through the strip-shaped holes 1b 3.

As shown in fig. 3, the two longitudinal support assemblies 1 are transversely provided with a transverse support pipe frame 2 below the front and rear ends, and the two ends of the transverse support pipe frame 2 are fixedly connected with the corresponding longitudinal pipe frame 1a through the vertical support pipe frame 3. In this embodiment, the lateral support pipe frame 2 is formed of two steel pipes arranged in parallel. Since the box girder 6 of the bridge is supported at the upper end of the pier 5 by the support 7, a certain gap is formed between the box girder 6 and the pier 5, and during the bridge deck widening construction, the steel pipe for transversely supporting the pipe frame 2 is transversely arranged between the gap between the box girder 6 and the pier 5 and is supported at the upper end of the pier 5.
