Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of supporting scaffolds, and particularly refers to a reinforcing device for the main ribs of steel pipes of a support frame. Background Art
[0002] For areas with components such as thick plates and deep beams in underground garages, etc., the traditional socketed disc-type scaffold is limited by the flexural capacity of the main ribs (the main ribs bear a large bending moment at the support position), and the transverse and longitudinal spacing generally does not exceed 900 mm, resulting in a large waste of the bearing capacity of the vertical poles. At the same time, due to the large amount of rod materials required, the material cost and labor cost are also increased. Content of the Utility Model
[0003] The purpose of the utility model is to overcome the defects of the prior art and provide a reinforcing device for the main ribs of steel pipes of a support frame, so as to solve the problem that the existing main ribs of steel pipes of the support frame use more vertical poles for support due to the limitation of the flexural capacity, resulting in material waste.
[0004] The utility model provides a reinforcing device for the main ribs of steel pipes of a support frame, which is used to reinforce the connection between the steel pipe main ribs and the vertical poles. The technical solution is as follows: the reinforcing device includes: a support seat fixedly arranged at the upper end of the vertical pole, and the steel pipe main rib is located on the support seat; a reinforcing pipe arranged on the outer side surface of the steel pipe main rib; and a locking mechanism arranged at both ends of the reinforcing pipe for fixing the reinforcing pipe.
[0005] Further, the support seat is U-shaped and the heights at both ends are equal to the diameter of the steel pipe main rib.
[0006] Further, the outer side surface of the reinforcing pipe is a plane and is provided with a 90° edge, and the outer side surface of the reinforcing pipe is attached to the inner wall of the support seat.
[0007] Further, the inner side surface of the reinforcing pipe forms an arc surface that fits the outer side surface of the steel pipe main rib.
[0008] Further, the locking mechanism includes: two clamping plates hinged at the lower end, and the two clamping plates clamp the left and right sides of the reinforcing pipe; a protruding part arranged at the upper end of the clamping plate; and a connecting piece passing through the protruding part at the upper end of the clamping plate.
[0009] Further, the locking mechanism further includes: a hinge piece arranged at the lower ends of the two clamping plates.
[0010] Further, the connecting piece is a tension bolt.
[0011] Compared with the prior art, the utility model has the following beneficial effects:
[0012] By setting the support base and the reinforcing pipe on the outer wall of the steel pipe main joist, the bending resistance performance of the steel pipe main joist is improved, so that columns can be set at a farther interval below the steel pipe main joist, thus saving materials.
[0013] By setting the inner side surface of the reinforcing pipe as an arc surface, the contact area between the inner side surface of the reinforcing pipe and the outer wall of the steel pipe main joist is larger and the fitting is closer, thus preventing stress concentration from damaging the reinforcing pipe and the steel pipe main joist.
