Detailed Description
For a better understanding of the objects, structures and functions of the present utility model, a sliding arch support system according to the present utility model will be described in further detail with reference to the accompanying drawings.
Example 1
As shown in fig. 1 to 4, a sliding arch support system comprises an arch steel beam 1 and a walking rail 6, wherein the walking rail 6 is arranged at two ends of the arch steel beam 1, the walking rail 6 is connected with the arch steel beam 1 through a sliding seat 5, and the walking rail 6 is arranged on a falling frame 7. The slide seat 5 enables the arched girder 1 to slide on the running rail 6, so that the transverse position of the arched girder 1 can be conveniently adjusted. The falling frame 7 reduces the height of the arched girder 1 in demolding, so that the main body structure after pouring is separated from the template.
In the technical scheme application process of the application, at the formwork in-process, be equipped with square timber 2 on the arch girder steel 1, be equipped with plywood 3 on the square timber 2.
In the application process of the technical scheme of the application, the concrete structure of the falling frame 7 comprises a pair of steel wedges 71, wherein the steel wedges 71 are wedge-shaped boxes, and the two steel wedges 71 are combined together to form a rectangular box. The steel wedges 71 are connected through screw steels 72, and two ends of the screw steels 72 are locked through nuts. By adjusting the positions of nuts at the two ends of the screw steel 72, the distance between the two steel wedges 71 can be controlled, and the combined height of the steel wedges 71 can be further controlled.
When demoulding is required, the nuts are loosened, the distance between the nut pieces is increased, the steel wedges 71 slide downwards relatively under the action of gravity above, and the height of the arched steel beam 1 is reduced. In the formwork supporting process, the distance between the steel wedges 71 is compressed through the locking nuts, the steel wedges 71 slide upwards relatively, and the height of the arched steel beam 1 is raised.
Example 2
In this embodiment, a connection block 4 is movably disposed at the end of the arched girder 1, and the connection block 4 is connected with a sliding seat 5.
In the technical scheme application process of the application, the connecting block 4 is rectangular block-shaped, and the tail end of the arched steel beam 1 is connected with the connecting block 4 through a rotating shaft.
The connecting blocks 4 on the same side at the tail end of the arched girder 1 are connected in series through the traction screw 602. The traction screw 602 is connected with a jack 601 arranged on the walking rail 6, and the transverse movement of the arched steel beam 1 on the walking rail 6 is realized through the thrust of the jack 601.
