[0002] The steel corrugated plate arch bridge culvert combined with steel corrugated plate and concrete is a new type of structure. During the construction process, concrete pouring on the steel corrugated plate is a key link. There is no formwork suitable for this new structure in the traditional formwork. Moreover, the processing accuracy of traditional wooden formwork is low, the surface is not smooth enough, and it is not convenient to connect in the arch structure, so it is not suitable for use in the construction of steel corrugated plate arch bridges and culverts combined with steel corrugated plates and concrete

Embodiment Construction
[0014] The present invention is composed of a plurality of formwork segments connected, and each formwork segment is composed of a top plate 1, a side plate 2 and a fixed side 3 respectively.
[0015] figure 1 It is shown that the top plate 1 and the side plate 2 are respectively rectangular small steel corrugated plates, and the fixed side 3 is a long flat steel plate. Their connection structure is that the two side plates 2 are vertically connected to both sides of the top plate 1 respectively, and the bottom sides of the two side plates 2 are respectively vertically connected with the fixed side 3, and the fixed side 3 is evenly distributed with screws along the length direction. hole.
[0016] figure 1 It shows that the length direction of the crests and troughs of the top plate 1 is perpendicular to the length direction of the top plate 1 , and the crests and troughs of the side plate 2 are correspondingly connected with the peaks and troughs of the top plate 1 . Since...

The invention provides an external template applicable to steel-concrete composite steel corrugated plate arch bridge and culvert and belongs to the technical field of steel corrugated plate structures. The external template applicable to steel-concrete composite steel corrugated plate arch bridge and culvert is used for concrete pouring of the steel corrugated plate and concrete composite steel corrugated plate arch bridge and culvert. According to the technical scheme, the external template applicable to the steel-concrete composite steel corrugated plate arch bridge and culvert comprises multiple template segments connected with each other; and each template segment correspondingly comprises a top plate, side plates and a fixed edge, wherein the top plate and the side plates are correspondingly oblong small-sized steel corrugated plate pieces; the fixed edge is a long strip-shaped plane steel plate; the two side plates are vertically connected to the two sides of the top plate; thelength directions of a wave peak and a wave valley of the top plate are perpendicular to the length direction of the top plate; wave peaks and wave valleys of the side plates are correspondingly connected with the wave peak and the wave valley of the top plate; the external sides of the bottom edges of the two side plates are vertically connected with the fixed edge; and screw holes are uniformlyformed in the fixed edge. According to the external template applicable to steel-concrete composite steel corrugated plate arch bridge and culvert, the structure is simple and scientific, the externaltemplate can be synchronous with the arched shape of the steel corrugated plate of a main body structure, a joint is tight and does not leak slurry, enough strength, rigidity and stability are realized, and the construction progress can be accelerated.
Description
