Semiautomatic propelling construction mechanism for bridge parapet

Abstract

The present invention aims at raising the construction quality, speed and safety of bridge parapet constructing mechanism. One of the constructino mechanism includes one working bench with wheels at bottom, crossbeam on one side, one construction frame on the crossbeam, inner and outer formworks corresponding to the outer shape of the parapet with the inner and outer formworks being capable of shifting horizontally and with connecting and pressure resisting part in between. The other scheme includes one inverted U-shaped working bench with wheels at bottom, one formworks corresponding the outer shape of the central separating island of bridger road, and the formworks can shift horizontally and have connecting pressure resisting rod. The mechanical of the present invention is used mainly in bridge construction.

Description

Technical field: [0001] The utility model relates to special equipment for bridges, in particular to construction equipment for bridge parapets. Background technique: [0002] The traditional bridge parapet construction method mainly uses two molds to be fixed on the ground with fixing bolts, and then uses the tie rods for positioning to withstand the pressure of concrete grouting. In order to avoid ring collapse, the formwork must be removed after it is completely solidified. Moreover, due to the positioning of tie rods, holes will be formed on the finished product, and repair work is required, which consumes construction time; in addition, when the construction ground is uneven, the entire line of the completed parapet wall cannot reach the same height and levelness, and must be further detailed What is more serious is that during the fixed construction, it is necessary to drill holes on the construction road surface to set the fixing bolts, so that the pressure of groutin...

[0002] The traditional bridge parapet construction method mainly uses two molds to be fixed on the ground with fixing bolts, and then uses the tie rods for positioning to withstand the pressure of concrete grouting. In order to avoid ring collapse, the formwork must be removed after it is completely solidified. Moreover, due to the positioning of tie rods, holes will be formed on the finished product, and repair work is required, which consumes construction time; in addition, when the construction ground is uneven, the entire line of the completed parapet wall cannot reach the same height and levelness, and must be further detailed What is more serious is that during the fixed construction, it is necessary to drill holes on the construction road surface to set the fixing bolts, so that the pressure of grouting is all borne by the bridge road surface, which will destroy the strength of the bridge deck but is difficult to find, seriously affecting the bridge structure. Desperately in need of improvement
