Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of building structure installation engineering, and particularly relates to a purlin quick installation tool. Background Art
[0002] During the construction of steel structure purlins, the common method for installing steel structure wall purlins is to manually hoist the wall purlins to the installation location using ropes attached to pulleys above the steel beams. Personnel on either side of the steel column purlin support manually secure the wall purlins to the steel column purlin support, and then manually release the hoisting rope locks. However, this method can only install one wall purlin at a time, resulting in slow installation and low work efficiency, which affects the project progress. This construction method is entirely manual and requires the coordination of multiple people, resulting in high labor costs and increased construction costs. Furthermore, the labor intensity is high, posing safety risks. Utility Model Content
[0003] In order to overcome the defects of the existing technology, the technical problem solved by the utility model is to provide a purlin quick installation tool, which uses a conventional crawler crane or a truck crane to lift the purlins. The tool can achieve the construction effect of quickly constructing multiple purlins at the same time, the purlin spacing can be adjusted according to the drawings, the purlins can be quickly put into place, and the purlin clamps can be quickly removed.
[0004] The two ends of the crossbar are welded to the upper and lower ends of the crossbar, and the upper and lower ends of the crossbar are welded to the crossbar symmetrically, and the lower end of the crossbar is on the outside of the upper end of the crossbar. The two upper ends of the crossbar serve as hanging points for the lifting rope of the lifting machinery, and the two lower ends of the crossbar are respectively hung on the chain; the chain is an elliptical chain chain, and the clamp can be hung on each chain ring. At the same time, more than two clamps can be hung on the chain, and the clamp is bent or welded into a square frame with three sides with the inner angle of the angle steel facing outward. A circular hole is provided on the top of the front wing plate of the angle steel on the inside of the clamp, and the clamp is fixed to the chain using a fixing piece through the circular hole. Two screw holes are provided in the middle of the side wing plate of the angle steel on the outside of the clamp, bolts are screwed into the screw holes and the bolts are fixed with double nuts arranged on both sides of the screw holes, and the nuts are on the inside of the clamp. The nuts are adjusted to make the bolts move horizontally, so that the bolts are pressed against the purlin to stabilize the purlin.
[0005] Furthermore, the fixing member of the fixing fixture uses a pin or a clamp.
[0006] The beneficial effects of the present invention are as follows: the cross arm serves as the supporting component for the purlin hoist, and a conventional crawler crane or a truck crane is used instead of manual lifting operations; the purlin is fixed on two parallel clamps, and the installation of several wall purlins can be completed in one lifting operation, which greatly improves the lifting efficiency and speeds up the progress of the construction project; while saving labor costs and reducing construction costs, it can also reduce the labor intensity of workers and eliminate safety hazards.

[0011] Example 1: A purlin quick installation tool, including a crossarm 1, a chain 4 and a clamp 5. The crossarm 1 is a round steel bar with the same length as the purlin. The upper and lower ends of the crossarm 1 are respectively welded with lifting ears 2 symmetrically on the left and right. The lower lifting ear 2 is outside the upper lifting ear 2. The two upper lifting ears 2 serve as hanging points for the lifting machinery sling 3; the two lower lifting ears 2 are respectively hung with chains 4; the chain 4 is an elliptical interlocking chain, and each chain ring can be hung with a clamp 5. At the same time, 5-7 clamps 5 are hung on the chain 4 On the top, the clamp 5 is made of angle steel bent or welded into a three-sided square frame with the inner angle of the angle steel facing outward. A circular hole 6 is opened on the top of the front wing plate of the angle steel on the inside of the clamp 5. The clamp is fixed to the chain 4 using a clamp 9 through the circular hole 6. Two screw holes 7 are opened in the middle of the side wing plate of the angle steel on the outside of the clamp 5. Bolts 8 are screwed into the screw holes 7 and fixed with double nuts set on both sides of the screw holes. The nuts are on the inside of the clamp 5. The nuts are adjusted to make the bolts 8 move horizontally, so that the bolts 8 rest on the purlin to stabilize the purlin.
[0012] When in use, a conventional crawler crane or truck crane is used to lift the purlins, the crossarm 1 serves as the load-bearing structure for lifting the purlins as a whole, the chain 4 serves as the purlin hanging point, and the clamp 5 serves as the purlin fixing device. The clamp 5 is hung on the chain 4, and the purlin is fixed on two parallel clamps 5. After the purlins are installed in place, the clamp 5 is separated from the crossarm 1 together with the chain 4 and transferred to the next batch of purlins. Using this tool, 5 to 7 purlins can be quickly installed at the same time, and the purlin spacing can be adjusted according to installation requirements.
