[0003] At present, most of the external-mounted tower cranes are attached, that is, they are rooted from the ground, and the standard sections of the tower crane are used for cumulative lifting, and then the attached connectors are used to connect the standard section of the tower crane to the structure. And it affects the professional construction of the lower part of civil engineering, curtain wall and decoration, which in turn affects the overall construction progress

specific Embodiment approach
[0013] The preferred embodiment of the external hanging tower crane bracing frame of the present invention is:
[0014] It includes an upper support structure and a lower support structure, the upper support structure and the lower support structure respectively include two support beams, the two support beams are connected by a secondary beam, one end of the support beam is connected with an embedded part, the The outer sides of the two support beams are connected with horizontal support rods;
[0015] The upper part of the support beam of the lower support structure is connected with a diagonal stay rod, and the lower part of the support beam of the upper support structure is connected with a strut.
[0016] The horizontal support bar includes a long horizontal support bar and a short horizontal support bar, one end of the long horizontal support bar is connected to the end of the support beam, and one end of the short horizontal support bar is connected to the middle of the...
specific Embodiment
[0024] Such as figure 1 , 2 As shown, it includes: supporting beams, secondary beams, diagonal stays, horizontal support rods, struts, etc., and also includes supporting climbing frames for tower cranes (not shown in the figure).
[0025] After the tower crane is used in the independent height condition, it needs to be converted to the climbing condition in time. First of all, according to the predetermined attachment point position of the tower crane, during construction, the embedded parts of the attachment device should be pre-embedded. The anchor bars of the embedded steel plates of the embedded parts should be firmly spot-welded with the steel bars of the original structure to prevent displacement during concrete pouring. bit. Then weld the connecting corbel on the embedded steel plate, the positioning and elevation of the corbel must be strictly controlled
[0026] After the corbels are welded, use the ZSL1000 tower crane to install the lower support beam first, hoist...

Abstract
The invention discloses a plug-in tower crane support frame, comprising an upper support structure and a lower support structure. The upper support structure and the lower support structure respectively comprise two support beams connected through a secondary beam; one end of the support beam is connected with embedded parts; external sides of the two support beams are connected with horizontal support rods; the upper part of the support beam of the lower support structure is connected with a diagonal member; and the lower part of the support beam of the upper support structure is connected with a stay bar. The support frame can be used in lifting construction of the tower crane, avoid waste of standard sections of the tower crane, reduce the construction cost and avoid the influence on the construction of the substructure, and is helpful to improve the construction schedule.
Description
technical field [0001] The invention relates to a supporting device of a building tower crane, in particular to an externally hung tower crane supporting frame. Background technique [0002] In the construction of steel structure installation, tower crane is its main construction machine and plays an important role in it. At present, in various steel structure construction sites, especially in the construction of high-rise buildings, tower cranes mainly have two installation methods: internal climbing type and external hanging type. The installation method needs to be selected according to the structure of the building. [0003] At present, most of the external-mounted tower cranes are attached, that is, they are rooted from the ground, and the standard sections of the tower crane are used for cumulative lifting, and then the attached connectors are used to connect the standard section of the tower crane to the structure. And it affects the professional construction of the ...
