Detailed Description

The following detailed description of the embodiments of the present invention will be made with reference to the accompanying drawings. It is to be understood that the description of the embodiments herein is for purposes of illustration and explanation only and is not intended to limit the invention.

In the present invention, the use of directional terms such as "upper, lower, inner and outer" in the absence of a contrary intention is generally intended to refer to upper, lower, inner and outer as illustrated in the accompanying drawings.

According to the utility model discloses, an abdominal arch is provided. Referring to fig. 1, the main arch body 1, the main arch ring 2, the capping beam 3, the upright post 4 and the bridge deck 5 are included, the main arch ring 2 is erected on two banks, the main arch body 1 is located above the main arch ring 2, the capping beam 3 and the upright post 4 are arranged between the main arch bodies 1, the capping beam 3 is fixed on the upright post 4, the highest point of the capping beam 3 and the highest point of the main arch body 1 are located on the same horizontal plane, the bridge deck 5 is arranged on the capping beam 3 and the main arch body 1, one end of the upright post 4 far away from the main arch body 1 is fixed on the main arch ring 2, and according to actual use requirements, on the premise of ensuring stability, other materials are not filled in the main arch ring 2, so that the materials are saved.

Through the utility model discloses an abdominal arch, in the in-service use process of bridge, the abdominal arch body is in fact no longer actual atress, if the abdominal arch body no longer receives the thrust of horizontal direction, consequently when guaranteeing bridge stability, the cracked phenomenon of regularity can not appear again because of the lapse of time in the abdominal arch body.

Furthermore, the utility model discloses can also include link plate and shaped steel skeleton, the link plate can be hung outward on the shaped steel skeleton, abdominal arch body 1 is by hanging externally on the shaped steel skeleton the link plate is constituteed. Preferably, the hanging plate can be made of GFRC. The hanging plate is made into decoration by adopting GFRC. GFRC is an inorganic composite material which is prepared by using cement mortar containing additives as a base material and glass fiber as a reinforcing material through a special process. The high-strength light-weight fireproof door has the advantages of high strength, extra-strong durability, high fire resistance, simplicity in maintenance, no influence of weather or ultraviolet light, lightness, multiple colors and the like. And the GFRC parts can be made into various shapes, and the effects can be the shape texture and the effects of nature such as stone imitation, weathered stone imitation, metal imitation, wood grain imitation, sandstone imitation and the like.

The utility model discloses can also include the built-in fitting, the built-in fitting can set up in the bent cap 3, the built-in fitting is used for connecting shaped steel skeleton.

In addition, the steel framework can also comprise a plate beam, and the plate beam is fixed with the steel framework. The embedded parts can also be embedded in the plate girder, and the embedded parts embedded in the bent cap 3 or the plate girder all play a role in supporting the section steel framework and further supporting the hanging plate.

Preferably, reinforced concrete can be arranged around the profile steel framework for fixing, and the plate girder is arranged in the reinforced concrete. When guaranteeing that the shaped steel skeleton is fixed stable, compare with common abdominal arch, can also alleviate the utility model discloses the dead weight of abdominal arch. Through the plate girder that sets up in the reinforced concrete to further guarantee the utility model discloses a stability, further say, the plate girder can adopt hollow plate girder, further alleviates the utility model discloses the dead weight of abdominal arch.
