Description

One kind being used for inside-climbing tower crane steel construction switch rack and its construction method
Technical field
The present invention relates to one kind to be used for inside-climbing tower crane steel construction switch rack and its construction method, belongs 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.
Summary of the invention
That the object of the present invention is to provide a kind of structures is simple, safe and reliable, bearing capacity is strong is used for inside-climbing tower crane steel Structure switch rack and its construction method, to overcome deficiency in the prior art.
Technical solution of the present invention: one kind being used for inside-climbing tower crane steel construction switch rack and its construction method, including is 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.
Meanwhile the present invention also provides a kind of for the above-mentioned construction method for inside-climbing tower crane steel construction switch rack, first Pre-buried two groups of pull rods are distinguished within the walls in adjacent shearing, and then in the outer end welding steel of every group of pull rod, and welding is solid on the steel plate Determine steel corbel, and make between the steel corbels of two sides that there are differences in height, welds steel box-girder on the steel corbel of low level side at this time, then 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, then at the top of " H " section steel beam Conversion steel bench is welded and fixed in both ends, and " C " type frame is bolted to connection on the conversion steel bench at both ends, finally Inside-climbing tower crane is fixedly mounted on " C " type frame.
In the above method, the maximum spacing of the adjacent shear wall is no more than 7m.
In the above method, " H " section steel beam is horizontally disposed.
Due to the adoption of the above technical scheme, the present invention has the advantages that the present invention solves building level structural beams size It is too small, bearing capacity is poor, is unable to satisfy inside-climbing tower crane load, cause inside-climbing tower crane installation, operating difficulties technical problem.Cause This, the duration, assembly is flexible, simple to install, can be used in turn, is easy for construction, is economical and practical, is safe and reliable with saving by the present invention The advantages of, there is wide applicability and generalization.
Detailed description of the invention
Fig. 1 is the structural diagram of the present invention.
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
To make the objectives, technical solutions, and advantages of the present invention clearer, with reference to the accompanying drawings and examples to this hair It is bright to be described in further detail.
The embodiment of the present invention: the structural schematic diagram for inside-climbing tower crane steel construction switch rack is as shown in Figure 1, include pre-buried 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, is welded on steel plate 1 Steel corbel 2, and there are differences in height between the steel corbel 2 of two sides, are welded with steel box-girder 3 on the steel corbel 2 of low level side, 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, at the top of " H " section steel beam 4 Both ends are fixedly connected with conversion steel bench 5, and " C " type frame 6 is bolted to connection on the conversion steel bench 5 at both ends.It is described It is provided with billet 8 between the bottom at the top and " H " section steel beam 4 of steel corbel 2 or steel box-girder 3, for adjusting " H " section steel beam 4 Levelness.
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.
