Abstract
Description
The present invention relates to a jig for beam lifting of a prefabricated tent structure, and more particularly, to a beam lifting jig of a prefabricated tent structure that enables to safely lift a large beam of high loads without damage when installing or dismantling the prefabricated tent structure. It is about.
Recently, there has been an increase in the installation of prefabricated tent structures with membranes to maintain tension between beams.
Such a prefabricated tent structure has a lower material cost than a general structure, which not only lowers the construction cost, but also facilitates work, which shortens the construction period, and its unique appearance can cause a different aesthetic and has excellent durability and bad weather. It can be prepared for, and can be easily changed in size and shape, free from constraints on installation space, and easy to remove and transfer after installation, so that exhibition facilities, airport facilities, factory facilities, It is widely applied to military facilities, port facilities, sports facilities, and shopping malls.
On the other hand, in the prefabricated tent structure, the beam is made of metal so that the load thereof is not only large, but also depending on the size of the prefab tent structure, so that the beam is lifted by manpower during the installation or dismantling of the prefabricated tent structure. Difficulties follow.
For the above reason, in the installation or dismantling of the prefabricated tent structure, the beam is lifted by a crane, etc. When the rope connected to the crane is directly tied to the beam itself, the beam is lifted while the beam is lifted in a loose binding state. Not only there was a problem that could lead to the problem, in particular, the load is concentrated on a part of the beam in contact with the rope, there is a problem that the damage of the beam is often followed by bending or bending.
Therefore, the related art attempts to use a lifting jig when lifting and transporting a beam during the installation or dismantling of a prefabricated tent structure.
However, since the beam of the prefabricated tent structure has a morphological characteristic such as a flange for fixing the tent at both ends, there is a problem that it is difficult to apply the general lifting jig.
For this reason, the relevant field is attempting to develop a beam lifting jig for a prefabricated tent structure that can lift and transport the beam of the prefabricated tent structure safely and without damage when installing or dismantling the prefabricated tent structure. The situation is not getting satisfactory results.
The present invention has been proposed in view of the above circumstances, and provides a jig for beam lifting of a prefabricated tent structure to safely lift a large beam of high loads without damage when installing or dismantling the prefabricated tent structure. It is.
Beam lifting jig of prefabricated tent structure according to the present invention for achieving the above object,
A top plate having a protruding piece having a rope inserting hole for inserting a rope leading from the crane in the center of the upper body, and a bolt through hole extending from the upper portion to the lower portion at each corner of the body;
A lower plate facing the upper plate at regular intervals, the lower plate having a bolt through hole extending from an upper portion to a lower portion located at the same vertical line as each bolt through hole of the upper plate at each corner of the body;
A spacer having a washer in contact with a lower end of each bolt through hole of the upper plate and an upper end of each bolt through hole of the lower plate, and having a through hole having a larger diameter than the upper and lower bolt through holes of the upper plate and the lower plate;
A support pipe positioned between the spacers on the same vertical line in contact with the upper plate and the lower plate, the upper and lower ends of the support pipe being in contact with the through hole of the washer provided in the spacer;
Characterized in that it consists of a bolt through the vertical through the same vertical line provided in the upper plate and the lower plate, the nut is fastened to the lower end to maintain the binding state with the upper plate and the lower plate.
Beam lifting jig of the prefabricated tent structure according to the present invention, because the entire upper surface of the bottom plate is in close contact with the beam upper surface by the bolt fastening penetrating through the upper plate and the lower plate, and the bottom of the upper plate and the bottom of the beam can be tightly coupled to the beam. Since the support pipe is positioned between the upper plate and the lower plate to limit the binding force of the beam, it is possible to prevent the damage of the beam due to the accident and excessive binding of the beam during the beam lifting operation through the crane. It works.
