Description

Technical Field

[0001] The invention relates to the technical field of cantilever construction, in particular to an ultra-light hanging basket main truss. Background Art

[0002] The hanging basket is the main equipment in cantilever construction. According to the structural form, it can be divided into four types: truss type (including flat string unbalanced weight type, diamond, triangle, bowstring type, etc.), cable-stayed type (including triangular cable-stayed type and prestressed cable-stayed type), steel type and mixed type. The parallel truss hanging basket is generally not used due to its heavy weight. The triangular composite truss beam hanging basket has certain limitations in application due to its heavy weight. The bowstring truss hanging basket has a large number of rods, and its production and installation are cumbersome and easy to lose, making it difficult to monitor the equipment. The diamond truss hanging basket has the characteristics of simple structure, reasonable force and one-time movement into place. It is currently more commonly used in construction.

[0003] At present, the main truss of the diamond-shaped truss hanging basket is in the shape of a parallelogram or a diamond, and its main structure includes an upper beam, a lower beam, supporting beams on both sides, and a middle supporting vertical beam, a total of five supporting beams. This will cause the problem of heavy self-weight of the main truss. Summary of the invention

[0004] 1. Technical issues to be resolved

[0005] In view of the deficiencies in the prior art, the present invention provides an ultra-light hanging basket main truss, which solves the problem of the main truss having a heavy deadweight.

[0006] (II) Technical solution

[0007] To achieve the above objectives, the present invention is implemented through the following technical solutions: an ultra-light hanging basket main truss, including an upper crossbeam and a lower crossbeam, a main crossbeam is fixedly connected between the lower surface of the upper crossbeam and near the right edge and the upper surface of the lower crossbeam and near the left edge, limiting grooves are provided on the upper and lower surfaces of the main crossbeam, supporting beams are fixedly connected on the lower surface of the upper crossbeam and near the left edge and the upper surface of the lower crossbeam and near the right edge, a limiting block is fixedly connected to the inclined surface of the support beam, a cavity is provided inside the upper crossbeam and the lower crossbeam, a support member is fixedly connected to the inner surface of the cavity, and a through hole is provided on the surface of the support member. The main crossbeam is provided to facilitate the main support function. The top and bottom of the main crossbeam are respectively connected to the lower surface of the upper crossbeam and the upper surface of the lower crossbeam, and it is the main load-bearing structure of the main truss installation. The limit groove is provided to facilitate the cooperation with the limit block, so as to achieve the effect of improving the stability of the support beam installed on the main crossbeam. The cooperation between the limit block and the limit groove can effectively increase the contact area between the support beam and the main crossbeam. The support beam is provided to facilitate the positioning connection between the upper surface of the main crossbeam and the lower surface of the upper crossbeam, as well as the upper surface of the lower crossbeam and the lower surface of the main crossbeam. The support beam connects the lower surface of the upper crossbeam. The intersection of the two support beams and the main beam is located at the midpoint of the main beam, and the limit blocks are arranged to facilitate the cooperation with the limit grooves to increase the contact area with the main beam. The cavity is arranged to reduce the overall self-weight of the main truss. The support members are arranged to prevent the supporting performance of the upper and lower beams from being reduced due to the cavity. The through holes are arranged to reduce the self-weight of the support members, thereby further reducing the self-weight of the main truss.

[0008] Preferably, the cross-sectional shape of the limit block and the cross-sectional shape of the limit groove are both isosceles right triangles, and the number and position of the limit blocks correspond to the number and position of the limit grooves. The cross-sectional shape of the limit block and the limit groove is set to be an isosceles triangle in order to achieve a more uniform effect of lateral and longitudinal force.

[0009] Preferably, the cross-sectional shape of the support member is an "X" shape, and the number of the through holes is multiple, and the support performance can be effectively maximized by setting the cross-sectional shape of the support member to an "X" shape.

[0010] Working principle: The steel ingot is heated in a furnace, then taken out and forged with an air hammer to obtain the main beam 3 and support beam 4 required for assembling the main truss, then the steel ingot is heated and melted into molten iron to cooperate with a mold to obtain two half beams with a cavity, then the support member 8 is installed in the cavity of the two half beams, after the support member is installed, the two half beams are closed to form a complete beam, and the upper beam 1 and the lower beam 2 are obtained in turn using this method, and then the upper beam 1, the lower beam 2, the main beam 3 and the support beam 4 are assembled and welded in turn to obtain a main truss.

[0011] (III) Beneficial effects

[0012] The present invention provides an ultra-light hanging basket main truss, which has the following beneficial effects:

[0013] 1. The main truss adopts an upper crossbeam, a lower crossbeam, a main crossbeam and two supporting beams. Although there are still five main beams, the difference from the prior art is that the main crossbeam is used as the main supporting crossbeam, and the vertical beam is divided into two halves as two supporting beams. Therefore, compared with the prior art, one less main supporting crossbeam is used as a whole, which can effectively achieve the effect of reducing the deadweight of the main truss.

[0014] 2. By arranging cavities inside the upper beam and the lower beam, the deadweight of the main truss can be further reduced. At the same time, arranging support members inside the cavity can reduce the deadweight of the main truss without reducing the supporting performance of the upper beam and the lower beam.
