Abstract
The utility model relates to the technical field of steel structure construction, in particular to an auxiliary device used in the construction of an overhanging structure and a vertical face supporting structure; the method is characterized in that: comprises a sleeve, a fixed pipe, a sliding pipe and a chain block; the fixed pipe and the sliding pipe are sleeved in the sleeve, wherein one end of the fixed pipe is welded and fixed with the inner wall of the sleeve, the sliding pipe slides in the sleeve, and two ends of the inverted chain are fixed with the fixed pipe and the cantilever structure respectively. Compared with the traditional code plate, the device has the advantages that the sleeve sliding connection is used, the chord member can slide in the sleeve in a limiting mode, and the construction efficiency and the safety factor are higher.
Description
Technical Field
The utility model relates to a steel construction technical field specifically is an auxiliary device that is arranged in structure of encorbelmenting and facade bearing structure to be under construction.
Background
When the traditional pipe truss is installed, the butt joint adopts the methods of welding the code plate, measuring in place, temporarily fixing and welding the interface. The stacking plate is used as a butting device, the high-altitude operation amount is large for butting and installing the inclined vertical face supporting structure and the cantilever structure, and the butting quality of a butting port is difficult to ensure, so that the stacking plate is not suitable for the high-altitude installation of the special-shaped truss.
Disclosure of Invention
An object of the utility model is to overcome above-mentioned defect, to slope facade bearing structure's installation, provide an adopt sleeve pipe sliding connection's auxiliary device.
In order to achieve the above object, the present invention is realized as follows:
an auxiliary device used in the construction of an overhanging structure and a vertical supporting structure comprises a sleeve, a fixed pipe, a sliding pipe and a chain block; the fixed pipe and the sliding pipe are sleeved in the sleeve, wherein one end of the fixed pipe is welded and fixed with the inner wall of the sleeve, the sliding pipe slides in the sleeve, and two ends of the inverted chain are fixed with the fixed pipe and the cantilever structure respectively.
The device is used by adopting the following ideas:
aiming at three chords at the joint of the vertical surface supporting structure and the overhanging structure, respectively arranging a sleeve with the inner diameter equal to the outer diameter of the chord and the length of 300mm at the end part of the three chord tubes of the vertical surface supporting structure, exposing the end part of the chord at the upper part of the sleeve by 100mm, and welding the sleeve and the two ends of the chord of the vertical surface supporting structure by fillet weld; a section of the chord member of the cantilever truss corresponding to the vertical face supporting structure is not provided with a sleeve, and only a groove is formed; and after the structure is installed, cutting off the sleeve, and welding and connecting the pipe orifice with equal strength.
Compared with the traditional code plate, the device has the advantages that the sleeve sliding connection is used, the chord member can slide in the sleeve in a limiting mode, and the construction efficiency and the safety factor are higher. However, there is also a certain operation difficulty, that is, how to simultaneously install the movable ends of the three chords into the casing, and it is necessary to ensure that the chords have enough sliding margins and do not slide out of the casing, so that detailed construction technology needs to be performed on operators during construction, and reliability and safety of the casing at the node are ensured as much as possible.
Drawings
Fig. 1 is a schematic structural view of the auxiliary device.
Fig. 2 is a schematic view of the auxiliary device in use.
Detailed Description
The invention is further illustrated by the following specific examples.
As shown in fig. 1, an auxiliary device for the construction of an overhanging structure and a vertical supporting structure comprises a sleeve 1, a fixed pipe 2, a sliding pipe 3 and a chain block 4; fixed pipe 2, sliding tube 3 all overlap and establish in sleeve pipe 1, and wherein, the one end of fixed pipe 2 and sleeve pipe 1 inner wall welded fastening, sliding tube 3 slides in sleeve pipe 1, and the both ends of chain block 4 are fixed with fixed pipe 2 and structure of encorbelmenting respectively.
The device is used by adopting the following ideas:
aiming at three chords at the joint of the vertical face supporting structure and the cantilever structure, respectively arranging a sleeve with the inner diameter equal to the outer diameter of the chord and the length of 300mm at the end part of the three chord tubes of the vertical face supporting structure, exposing the end part of the chord at the upper part of the sleeve for 100mm, and performing girth welding on the sleeve and two ends of the chord of the vertical face supporting structure by using fillet welds; a section of the chord member of the cantilever truss corresponding to the vertical face supporting structure is not provided with a sleeve, and only a groove is formed; and after the structure is installed, cutting off the sleeve, and welding and connecting the pipe orifice with equal strength.
The specific use of the above device is as follows:
And 3, adjusting the chain block until the three sleeves on the vertical surface supporting structure are sleeved with the chord members of the cantilever structure respectively.
and 5, the upper sleeve joint can ensure that the steel structure can freely slide under the action of temperature and during subsequent unloading (the overhanging tail part slightly tilts upwards).
And 6, after the structure is installed, considering that the vertical surface supporting structure has a drawknot measure, the sleeve can be cut off, and meanwhile, the butt joint part of the pipes is welded to ensure equal-strength connection.
Compared with the traditional code plate, the device has the advantages that the sleeve sliding connection is used, the chord member can slide in the sleeve in a limiting mode, and the construction efficiency and the safety factor are higher. However, there is a certain operation difficulty, that is, how to simultaneously install the movable ends of the three chords into the casing, and it is necessary to ensure that the chords have enough sliding allowance and do not slide out of the casing. Therefore, during construction, detailed construction technology needs to be carried out on operators, and the reliability and the safety of the sleeve at the joint are guaranteed as much as possible.
