TECHNICAL FIELD

[0001] The utility model relates to prestressed T type prefabricated beam side formwork lifting appliance. BACKGROUND

[0002] When installing or removing the large formwork of the prestressed T type prefabricated beam, the lifting point is difficult to balance, the side formwork shakes greatly, and it is not easy to install and position, which can easily cause the formwork damage and other lifting operations. The traditional lifting operation welds the lifting lug on the large formwork, and the hook of the crane is directly inserted into the formwork lifting lug for lifting, which can easily cause the collision of the large formwork of the prestressed T type prefabricated beam, and cause the formwork deformation and damage. SUMMARY

[0003] The purpose of the present application is to provide a prestressed T type prefabricated beam side formwork lifting combined lifting appliance which is easy to process, low in cost, convenient to lift and position, fast, and effectively reduces the formwork damage caused by the shaking of the prestressed T type prefabricated beam side formwork and other operation safety problems.

[0004] The purpose of the present application is achieved as follows:

[0005] The prestressed T type prefabricated beam side formwork lifting combined lifting appliance is provided with symmetrical channel steel 5 welded on both sides of the bearing beam 4, a first lifting ring 6 welded on the upper center of the bearing beam 4, a row of symmetrical round holes at both ends of the lower part of the bearing beam 4, a lifting lug 2 welded in the first rectangular hole at one end of the left and right steel pole beam 1, a market sold shackle 3 inserted through the lifting lug 2 of the steel pole beam, and then inserted through the round holes at both ends of the lower part of the bearing beam to form the lifting point during hoisting. The second rectangular hole at the other end of the steel pole beam 1 is sleeved on the vertical steel fence 8 of the prestressed T type prefabricated beam side formwork, and the vertical steel fence is welded with the formwork 9 below the lifting lug through the connecting rod 12, the longitudinal purlin 10 and the transverse purlin 11. The limiting steel plate 14 welded on the steel pole beam 1 is located on one side of the vertical steel fence 8 for limiting and locking, and then wedged with the steel wedge or wooden wedge 7 to form the stress point during hoisting of the prestressed T type prefabricated beam side formwork. The left and right steel pole beams 1 are combined into a set of lifting appliances, and the prestressed T type prefabricated beam side formwork is kept balanced in the long axis direction during hoisting.

[0006] Advantages of the present application

[0007] The present application is accurate in positioning, stable in lifting operation of the side formwork, avoids large inclination collision, and causes deformation and damage of the side formwork. The stiffened plate bearing beam and pole beam combined lifting appliance improves the lifting operation of the prestressed T type prefabricated beam side formwork, which is easy to process, low in cost, convenient to lift, effectively reduces the formwork damage caused by the shaking of the prestressed T type prefabricated beam side formwork and other operation safety problems, and solves the disadvantages of the traditional lifting method of the prestressed T type prefabricated beam side formwork, such as not easy to install and position, etc. The lifting operation efficiency is improved at the lowest cost.

[0012] The prestressed T-shaped prefabricated beam side formwork hoisting assembly hoist is provided with symmetrical channel steel 5 welded on both sides of the load-bearing beam 4, the first lifting ring 6 is welded on the upper center of the load-bearing beam 4, there is a row of symmetrical round holes at both ends of the load-bearing beam 4, the second square hole of one end of the steel pole beam 1 is provided with a welded fixed lifting lug 2, the market sold shackle 3 is threaded through the lifting lug 2 of the steel pole beam, and then the round hole under the load-bearing beam is threaded to form a lifting point when hoisting, the first rectangular hole of the other end of the steel pole beam 1 is sleeved on the vertical steel fence 8 of the prestressed T-shaped prefabricated beam side formwork, the vertical steel fence is welded to the formwork 9 under the lifting lug 2 through the connecting rod 12, the longitudinal purlin 10 and the transverse purlin 11, and has a welding seam 13.

[0013] The limiting steel plate 14 is used for limiting and locking, and then the steel wedge or the wooden wedge 7 is tightly wedged, so that the stress point of the prestressed T-shaped prefabricated beam side formwork during hoisting is formed, the vertical steel fence 8 is a part that enhances the rigidity of the prestressed T-shaped prefabricated beam side formwork and is processed together with the formwork and is fixedly connected with the formwork through welding. Another steel pole beam 1 adopts the same operation method, and the two steel pole beams 1 are combined into a set of hoists, the connecting points of the steel pole beams at both ends of the load-bearing beam are determined according to the vertical steel fence spacing of the prestressed T-shaped prefabricated beam side formwork lifting point, and the friction force between the steel pole beam and the steel fence during hoisting is utilized to keep the prestressed T-shaped prefabricated beam side formwork balanced and stable along the long axis direction of the steel pole beam.
