Problems solved by technology
This support method can treat the two beams as a simply supported beam structure, and can ignore the influence of horizontal loads on the structure, but it may cause the wall to be subjected to a large normal force, and the damage of the normal force to the wall It has a large effect and affects the strength and life of the wall

Embodiment
[0040] Example: such as figure 1 As shown, a two-beam cross support structure of the present invention includes two support beams 1 with the same structure, a wall support 3, a movable hinge support 2 between the support beam and the wall support 3, one of which supports Beam CD has two sections, which are installed on both sides of another supporting beam AB to form a cross structure, such as image 3 As shown, rib plate I4 and reinforcement plate 5 are provided at the intersection of the two supporting beams to ensure the stability of the structure; during installation, the two ends of the two supporting beams are respectively connected to the wall support 3 through the movable hinge support 2 . This connection support method can resist the horizontal load and vertical load through the bending stiffness of the supporting beam, which can reduce the force on the wall and avoid the normal force on the wall, so that its overall stability can be effectively guaranteed.

The invention provides a supporting structure of a tower crane and belongs to the technical field of building machinery. The supporting structure of the tower crane comprises two supporting cross beams of the same structure, wall supports and movable hinged supports between the supporting cross beams and the wall supports. One supporting cross beam CD is composed of two sections, the two sections are installed on the two sides of the other supporting cross beam AB, and then a crisscross structure is formed. When the supporting structure of the tower crane is installed, the two ends of each supporting cross beam are connected with the corresponding wall supports through the corresponding movable hinged supports. The supporting structure of the tower crane is simple, reduces the production cost and is convenient to transport. The two ends of each supporting cross beam are supported by the corresponding wall supports both through the movable hinged supports, and therefore the problem of the action of normal force on a wall can be effectively solved. The installation position of the tower crane on the supporting structure can be adjusted according to the actual condition of a building and the own need of the tower crane, and therefore operation of the tower crane is facilitated.
Description
technical field [0001] The invention belongs to the technical field of construction machinery, and in particular relates to a tower crane support structure for high-rise buildings. Background technique [0002] In the later stage of construction of high-rise and super high-rise buildings, there will be a process of installing or dismantling the tower crane on the top of the building. Sometimes it is necessary to support the tower crane on the top of the core tube of the building with a bridge, and the structure supporting the bridge has a great impact on the structure of the tower crane and the wall. Security has a direct impact. At present, in building construction, the bridge structure used to support the tower crane on the top of the core tube of a high-rise building is mostly a three-beam structure or a four-beam structure. Compared with a two-beam cross structure, a three-beam or four-beam structure is slightly more complicated, which increases the The cost of manufact...
