Embodiment 1

[0029] Use two auxiliary steel pipes to hoist the purlins at the same time. The auxiliary steel pipes are composed of steel pipes 1, steel rings 2, steel rings 3, lifting rings 4, and lifting points 5. The steel rings 2 are welded on the steel pipes 1. The number of steel rings and the purlins required to be installed The number of steel rings 2 is the same, the distance between the steel rings 2 is the same as the distance between the roof beam purlins, the steel ring 3 is sleeved on the steel pipe 1 through the steel ring 2, and the lifting ring 4 is sleeved under the steel ring 3, The lifting points 5 are semicircular structures welded on the steel pipe 1 with steel bars, and the number is three. The steel ring 2 is made of steel bars with a thickness of 6 mm. The traveler 3 is made of steel bars with a thickness of 5 mm.

Embodiment 2

[0032] A purlin and a roof beam are simultaneously hoisted by an auxiliary steel pipe. The auxiliary steel pipe is composed of steel pipe 1, steel ring 2, steel ring 3, lifting ring 4 and lifting point 5. The steel ring 2 is welded on the steel pipe 1. The number of steel rings It is the same as the number of purlins required to be installed, the distance between the steel rings 2 is the same as the distance between the purlin brackets of the roof beam, the steel ring 3 passes through the steel ring 2 and is sleeved on the steel pipe 1, and the lifting ring 4 is sleeved on the steel pipe 1. Below the traveler 3, the lifting point 5 is a semicircular structure welded on the steel pipe 1 with steel bars, and the number is three. The steel ring 2 is made of steel bars with a thickness of 6 mm. The traveler 3 is made of steel bars with a thickness of 5 mm.

Embodiment 3

[0035] Use an auxiliary steel pipe to hoist the purlins and two roof beams at the same time. The auxiliary steel pipe is composed of steel pipe 1, steel ring 2, steel ring 3, lifting ring 4 and lifting point 5. The steel ring 2 is welded on the steel pipe 1. The number of steel rings It is the same as the number of purlins required to be installed, the distance between the steel rings 2 is the same as the distance between the purlin brackets of the roof beam, the steel ring 3 passes through the steel ring 2 and is sleeved on the steel pipe 1, and the lifting ring 4 is sleeved on the steel pipe 1. Below the traveler 3, the lifting point 5 is a semicircular structure welded on the steel pipe 1 with steel bars, and the number is three. The steel ring 2 is made of steel bars with a thickness of 6 mm. The traveler 3 is made of steel bars with a thickness of 5 mm.

Abstract

The invention relates to a method for lifting roof girders and purlines at the same time. According to the method, auxiliary steel pipes serve as supporting pieces, a plurality of purlines or purlines and roof girders are assembled into a whole on the ground, the angle of the position of a crane rope is adjusted, and the overall inclination of the purlines and the roof girders is made to be the same as the roof gradient; then, the purlines and roof girders are lifted to the corresponding position of the rood girders as a whole and mounted in sequence, and the auxiliary steel pipes are removed after mounting is completed. According to the method, three mounting schemes that the two auxiliary steel pipes are used at the same time, one auxiliary steel pipe and one roof girder are used, and one auxiliary steel pipe and two roof girders are used are provided, the angle and lifting schemes are adjusted flexibly according to the construction filed situation, construction can be carried out along with building projects, and engineering advance is promoted; meanwhile, the problems that a traditional mounting process is low in construction speed, poor in quality, high in risk and low in benefit are solved, the construction period is shortened, quality is promoted, and safety guarantee is enhanced.

Description

technical field [0001] The invention relates to a construction method of a pasture, in particular to a method for simultaneously hoisting roof beam purlins during the construction of a pasture shed with a light steel structure. Background technique [0002] Although the cost of light steel buildings is higher than that of ordinary traditional concrete structures, due to its advantages of fast construction, energy saving and emission reduction, it has been recognized by more and more construction industries. It has entered a period of rapid development in our country and has been widely used in various industries. . [0003] Pasture pens are very suitable for the use of light steel structures, but pastures, especially dairy farms, generally have a large span. Due to the large coverage, the design and construction of light steel cowsheds have more requirements for roof beams and purlins. high. Especially in the installation of purlins, at present, manual construction is the ...
