Abstract
The utility model discloses a support frame for a 321 type bailey trestle, which comprises side beams, cross beams, inclined struts, connecting seats and vertical beams, wherein the two side beams are symmetrically arranged, the two cross beams are mutually parallel and fixed between the two side beams, the cross beams are perpendicular to the side beams, a plurality of inclined struts and vertical beams are fixed in front of the two cross beams, the vertical beams are parallel to the side beams, the length of the vertical beams is shorter than that of the side beams, the connecting seats are fixed on two sides of each side beam, and the connecting seats are arranged on the outer sides of the corresponding side beams. The length of the vertical beam is shorter than that of the side beam, and the support frame bridge is fixedly connected by rotating the bolts in the threaded through holes on the connecting seat during installation, so that the cross beam can avoid to the clamp hole sites on the bridge, and no adverse effect is caused to the subsequent installation of the bridge.
Description
Technical field:
the utility model relates to a support frame for a 321 type bailey trestle.
The background technology is as follows:
the original support frame is universal in industry, and under the condition of vertical installation, the support frame can shield the hole site of the beam clamp, so that the installation of the subsequent beam clamp is affected, the firmness of the beam clamp installation cannot be ensured, and the use of a bridge is threatened.
The utility model comprises the following steps:
the utility model provides a support frame for a 321 type bailey trestle for solving the problems in the prior art.
The utility model adopts the technical scheme that:
the utility model provides a support frame for 321 type bailey landing stage, includes curb girder, crossbeam, bracing, connecting seat and perpendicular roof beam, two curb girders symmetrical arrangement, and two crossbeams are mutually parallel fix between two curb girders, and the crossbeam is mutually perpendicular with the curb girder, fixed a plurality of bracing and perpendicular roof beam before two crossbeams, perpendicular roof beam is parallel with the curb girder, and the length of perpendicular roof beam is shorter than the length of curb girder, all fixes a connecting seat in the both sides of every curb girder, the connecting seat is arranged in the outside of corresponding side crossbeam.
Further, the side beam is of an angle steel structure with a vertical side and a horizontal side, the cross beam is welded with the vertical side of the side beam, and the connecting seat is welded on the horizontal side of the side beam.
Further, the connecting seat is provided with a threaded through hole.
The utility model has the following beneficial effects:
the length of the vertical beam is shorter than that of the side beam, and the support frame bridge is fixedly connected by rotating the bolts in the threaded through holes on the connecting seat during installation, so that the cross beam can avoid to the clamp hole sites on the bridge, and no adverse effect is caused to the subsequent installation of the bridge.
Description of the drawings:
fig. 1 is a front view of the present utility model.
Fig. 2 is a top view of the present utility model.
Fig. 3 is a side view of the present utility model.
Fig. 4 is a view showing the construction of the attachment seat of the present utility model attached to the side member.
Fig. 5 is a diagram showing an application structure of the present utility model.
The specific embodiment is as follows:
the utility model is further described below with reference to the accompanying drawings.
As shown in fig. 1 to 4, the support frame for a type 321 bailey trestle of the present utility model comprises side beams 1, cross beams 2, diagonal braces 3, connecting seats 4 and vertical beams 5, wherein the two side beams 1 are symmetrically arranged, the two cross beams 2 are mutually parallel and fixed between the two side beams 1, the cross beams 2 are perpendicular to the side beams 1, a plurality of diagonal braces 3 and vertical beams 5 are fixed in front of the two cross beams 2, the vertical beams 5 are parallel to the side beams 1, the length of the vertical beams 5 is shorter than that of the side beams 1, one connecting seat 4 is fixed at both sides of each side beam 1, and the connecting seats 4 are arranged at the outer sides of the corresponding side beams 2.
The side beam 1 is of an angle steel structure with a vertical side and a horizontal side, the cross beam 2 is welded with the vertical side of the side beam 1, and the connecting seat 4 is welded on the horizontal side of the side beam 1. The connecting seat 4 is provided with a threaded through hole.
In combination with fig. 5, the length of the vertical beam 5 is shorter than that of the side beam 1, and the support frame bridge is fixedly connected by rotating a bolt in a threaded through hole on the connecting seat 4 during installation, so that the cross beam 2 can avoid to the clamp hole site 100 on the bridge, and the subsequent installation of the bridge is not affected.
