Abstract
The utility model discloses a kind of inside-climbing tower crane steel construction switch racks for 7m span, including being embedded in the two groups of pull rods of adjacent shearing within the walls, the outer end of every group of pull rod is welded with steel plate, it is welded with steel corbel on the steel plate, and there are differences in height between the steel corbel of two sides, steel box-girder is welded on the steel corbel of low level side, the both ends of " H " section steel beam are separately fixed at the steel corbel of high-order side and the top of steel box-girder, conversion steel bench is fixedly connected at the top both ends of " H " section steel beam, " C " type frame is bolted to connection on the conversion steel bench at both ends.The utility model solves that building level structural beams are undersized, bearing capacity is poor, is unable to satisfy inside-climbing tower crane load, leads to the technical problem of inside-climbing tower crane installation, operating difficulties.Therefore, the utility model has the advantages that the saving duration, assembly is flexible, simple to install, can be used in turn, is easy for construction, is economical and practical, is safe and reliable, has wide applicability and generalization.
Description
Technical field
The utility model relates to a kind of inside-climbing tower crane steel construction switch racks for 7m span, belong to lifting in architectural engineering
Equipment technical field.
Background technique
Currently, horizontal structure beam section size is smaller in most of building core cylinder, inside-climbing tower crane work lotus cannot be born
Carry, and vertically can bearing load structure spacing be less than 7m when, inside-climbing tower crane installation it is particularly difficult.It is asked to solve above-mentioned technology
Topic, conventional method are the water for improving its bearing capacity by increasing the area of section of building level structural beams, and thickening or widening
Flat structure beam not only makes troubles to subsequent construction, but also influences building beauty, and the later period is needed to carry out picking chisel modification, waste thus
Man power and material influences construction efficiency.
Utility model content
That the purpose of the utility model is to provide a kind of structures is simple, safe and reliable, bearing capacity is strong is used for 7m span
Inside-climbing tower crane steel construction switch rack, to overcome deficiency in the prior art.
The technical solution of the utility model includes: a kind of inside-climbing tower crane steel construction switch rack for 7m span, including be embedded in
The two groups of pull rods of adjacent shearing within the walls, the outer end of every group of pull rod are welded with steel plate, are welded with steel corbel on the steel plate,
And there are differences in height between the steel corbel of two sides, are welded with steel box-girder on the steel corbel of low level side, the two of " H " section steel beam
End is separately fixed at the steel corbel of high-order side and the top of steel box-girder, is fixedly connected with and turns at the top both ends of " H " section steel beam
Steel bench is changed, " C " type frame is bolted to connection on the conversion steel bench at both ends.
Further, billet is provided between the bottom at the top and " H " section steel beam of the steel corbel or steel box-girder.
Due to the adoption of the above technical scheme, utility model has the advantages that the utility model solves building level knot
Structure beam is undersized, bearing capacity is poor, is unable to satisfy inside-climbing tower crane load, leads to the technology of inside-climbing tower crane installation, operating difficulties
Problem.Therefore, the duration, assembly is flexible, simple to install, can be used in turn, is easy for construction, economic reality with saving for the utility model
With, safe and reliable advantage, there is wide applicability and generalization.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Description of symbols: 1- steel plate, 2- steel corbel, 3- steel box-girder, 4- " H " section steel beam, 5- convert steel bench, 6- " C "
Type frame, 7- pull rod, 8- billet.
Specific embodiment
It is right with reference to the accompanying drawings and examples in order to keep the purpose of this utility model, technical solution and advantage clearer
The utility model is described in further detail.
The embodiments of the present invention: structural schematic diagram such as Fig. 1 of the inside-climbing tower crane steel construction switch rack for 7m span
Shown, including being embedded in the two groups of pull rods 7 of adjacent shearing within the walls, the outer end of every group of pull rod 7 is welded with steel plate 1, in steel plate 1
On be welded with steel corbel 2, and there are differences in height between the steel corbel 2 of two sides, are welded and fixed on the steel corbel 2 of low level side
There is steel box-girder 3, the both ends of " H " section steel beam 4 are separately fixed at the steel corbel 2 of high-order side and the top of steel box-girder 3, in " H " type
The top both ends of girder steel 4 are fixedly connected with conversion steel bench 5, and " C " type frame 6 is bolted to connection the conversion steel plate at both ends
On stool 5.It is provided with billet 8 between the bottom at the top and " H " section steel beam 4 of the steel corbel 2 or steel box-girder 3, for adjusting
The levelness of " H " section steel beam 4.
When the bearing capacity for determining horizontal structure beam in original structure design be unable to satisfy under working condition inside-climbing tower crane load or
When shear wall maximum spacing is not more than 7m when using shear wall as inside-climbing tower crane stress point, above-mentioned conversion frame can be used to install
Inside-climbing tower crane.
When construction, pre-buried two groups of pull rods 7 are distinguished within the walls in adjacent shearing first, are then welded in the outer end of every group of pull rod 7
Steel plate 1, and steel corbel 2 is welded and fixed on steel plate 1, and make between the steel corbels 2 of two sides that there are differences in height, at this time in low level side
Steel corbel 2 on weld steel box-girder 3, then the both ends of " H " section steel beam 4 are separately fixed to the steel corbel 2 and steel of high-order side
The top of box beam 3, then conversion steel bench 5 is welded and fixed at the top both ends of " H " section steel beam 4, " C " type frame 6 is solid by bolt
Surely it is connected on the conversion steel bench 5 at both ends, inside-climbing tower crane can be finally fixedly mounted on " C " type frame 6.
