Abstract
The utility model relates to an adjustable temporary tensioning device for hoisting a side-lever-free truss; the lifting device comprises a first lifting lug, a second lifting lug, a steel wire rope and a chain block; the first lifting lug is connected with the upper chord of the truss, the second lifting lug is connected with the lower chord of the truss, and the steel wire rope is connected with the first lifting lug and the second lifting lug through a chain block; the inverted chain is used for tensioning the upper chord member and the lower chord member of the truss, so that the effect of improving the overall stability and the structural strength of the truss side rod during hoisting is replaced. The utility model provides an interim overspeed device tensioner, it constitutes simply, easily equipment, conveniently draw materials, install when truss ground is assembled, carry out the tensioning through adjusting the chain block before the truss hoist and mount, make originally unstable truss structure system form stable truss structure system under the condition of chain block tensioning, size between the upper and lower chord of tensioning degree control truss that also can be through adjusting the chain block simultaneously, make things convenient for high altitude and bracket butt joint for construction speed and the high altitude construction volume that has reduced.
Description
Technical Field
The utility model relates to a construction technical field of steel construction specifically is an adjustable interim overspeed device tensioner for hoist and mount of no side lever truss.
Background
In steel structure construction, a truss is usually connected with a steel column through a bracket, the truss is assembled on the ground or hoisted after the whole truss enters the field, and web members at two sides of the truss are usually connected with the steel column and the truss in a single stop supplementing mode to ensure that the truss reaches a designed state. However, when the truss is assembled due to the fact that the web members at the outermost side of the truss with the small number of the web members are installed later, a stable structural system cannot be formed, and great inconvenience is brought to field installation.
In the above situation, the truss can only be installed in bulk at high altitude, which results in slow construction speed and increased overhead work amount, and the method consumes relatively much time and labor for truss construction, thereby greatly increasing the risk source and construction cost of site construction.
Disclosure of Invention
An object of the utility model is to overcome above-mentioned defect, provide a replace truss avris web member make the whole pin in truss ground assemble, the whole pin installation in high altitude become possible interim overspeed device tensioner.
In order to achieve the above object, the present invention is realized as follows:
the utility model provides an adjustable interim overspeed device tensioner for truss hoist and mount which characterized by: the lifting device comprises first lifting lugs (1 and 5) arranged below an upper chord (9) of a truss, second lifting lugs (4 and 8) arranged above a lower chord (10) of the truss, steel wire ropes (2 and 6) for connecting the first lifting lugs (1 and 5) and the second lifting lugs (4 and 8), and chain blocks (3 and 7) arranged on the steel wire ropes (2 and 6) in a penetrating manner; the steel wire ropes (2 and 6) are respectively connected with the first lifting lugs (1 and 5) and the second lifting lugs (4 and 8) through the inverted chains (3 and 7); the inverted chains (3 and 7) are used for tensioning the truss upper chord (9) and the truss lower chord (10), so that the effect of improving the overall stability and the structural strength of the truss side rods in hoisting is replaced.
The utility model provides an interim overspeed device tensioner, it constitutes simply, easily equipment, conveniently draw materials, install when truss ground is assembled, carry out the tensioning through adjusting the chain block before truss hoist and mount, make originally unstable truss structure system form stable truss structure system under the condition of chain block tensioning, size between the upper and lower chord member of tensioning degree control truss that also can be through adjusting the chain block simultaneously, make things convenient for high altitude and bracket butt joint, construction speed has been accelerated and the high altitude construction volume has been reduced, thereby reduce the on-the-spot danger source, construction safety has been guaranteed. Meanwhile, the device can be used in a matched and recycling mode, the truss can be quickly disassembled after being in place and the web member is completed, unnecessary measure materials are reduced, construction cost is saved, and economy is highlighted.

Detailed Description
The invention is further illustrated by the following specific examples.
As shown in fig. 1, an adjustable temporary tensioning device for truss hoisting is characterized in that: the lifting device comprises first lifting lugs (1 and 5) arranged below an upper chord (9) of a truss, second lifting lugs (4 and 8) arranged above a lower chord (10) of the truss, steel wire ropes (2 and 6) for connecting the first lifting lugs (1 and 5) and the second lifting lugs (4 and 8), and chain blocks (3 and 7) arranged on the steel wire ropes (2 and 6) in a penetrating manner; the first lifting lugs (1 and 5) are welded with an upper truss chord (9), the second lifting lugs (4 and 8) are welded with a lower truss chord (10), and the steel wire ropes (2 and 6) are respectively connected with the first lifting lugs (1 and 5) and the second lifting lugs (4 and 8) through the chain blocks (3 and 7); the inverted chains (3 and 7) are used for tensioning the truss upper chord (9) and the truss lower chord (10), so that the effect of improving the overall stability and the structural strength of the truss side rods in hoisting is replaced.
The utility model provides an interim overspeed device tensioner, it constitutes simply, easily equipment, conveniently draw materials, install when truss ground is assembled, carry out the tensioning through adjusting the chain block before truss hoist and mount, make originally unstable truss structure system form stable truss structure system under the condition of chain block tensioning, size between the upper and lower chord member of tensioning degree control truss that also can be through adjusting the chain block simultaneously, make things convenient for high altitude and bracket butt joint, construction speed has been accelerated and the high altitude construction volume has been reduced, thereby reduce the on-the-spot danger source, construction safety has been guaranteed. Meanwhile, the device can be matched and recycled, and can be quickly disassembled after the truss is in place and the web member is completed, so that unnecessary measure materials are reduced, the construction cost is saved, and the economical efficiency is highlighted.
