Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of hoisting, in particular to a temporarily enhanced tensile node applicable to cold-formed thin-walled steel structures. Background Technique
[0002] In recent years, with the continuous spread of the modular concept in prefabricated buildings, the functional integration of building modules has been continuously improved. Cold-formed thin-walled steel structures are more economical than traditional steel structures due to the strength enhancement obtained after cold bending of steel, and are widely used in prefabricated buildings.
[0003] However, the force-bearing modes of box modules are significantly different during the hoisting process and normal use. This difference has no obvious impact on welded joints. However, since the walls and floors of cold-formed thin-walled steel structures are connected by self-tapping and self-drilling screws, their tensile bearing capacity is much weaker than the compressive bearing capacity. This results in a risk of local tensile failure at the lifting points of box modules designed according to the normal use process during the hoisting process.
[0004] On the other hand, if the box module is designed according to the hoisting process, there will be more redundancy during normal use, resulting in waste. When adopting the bottom hoisting scheme, the hoisting components will exceed the outer contour of the module, and interference will occur during the positioning with the direct contact between modules, bringing additional module movement work. Summary of the Utility Model
[0005] The purpose of the utility model is to provide a temporarily enhanced tensile node applicable to cold-formed thin-walled steel structures to solve the problem that the tensile bearing capacity of the walls and floors of cold-formed thin-walled steel structures is much weaker than the compressive bearing capacity during the hoisting process, resulting in local tensile failure.
[0006] Technical Solution: The utility model provides a temporarily enhanced tensile node applicable to cold-formed thin-walled steel structures, including: a module beam, vertical stiffeners, lifting rings, and lifting ropes. The module beam includes: a bottom guide beam and a top guide beam. A wall module is arranged between the bottom guide beam and the top guide beam, and a floor beam is arranged below the bottom guide beam; the vertical stiffeners are arranged at the inner corner connection ends of the floor beam and are connected by self-tapping and self-drilling screws; there are two groups of lifting rings, which are respectively arranged at the connection between the bottom guide beam and the wall module, and at the connection between the wall module and the top guide beam, and are arranged in the same straight line direction; the lifting ropes are connected between the lifting rings at both ends inside the wall module, and a turnbuckle is arranged in the middle of the lifting ropes. The enhanced tensile node can avoid the problem of tensile failure caused by large local tensile force during hoisting. The vertical stiffeners can evenly transfer the received tensile force to the upper and lower flanges and webs of the floor beam, preventing the bottom guide beam from deforming and bending.
[0007] Further, for the above-mentioned node for temporarily enhancing tension applicable to cold-formed thin-walled steel structures, the bottom guide beam, top guide beam, and floor beam are all made of cold-formed thin-walled U-shaped steel, and the outer frame of the wall module is a light steel keel made of cold-formed C-shaped steel.
[0008] Further, for the above-mentioned node for temporarily enhancing tension applicable to cold-formed thin-walled steel structures, the vertical stiffener is made of C-shaped steel and is tightly connected to the web and upper and lower flanges of the floor beam.
[0009] Further, for the above-mentioned node for temporarily enhancing tension applicable to cold-formed thin-walled steel structures, the lifting ring is arranged inside the vertical stiffener in the floor beam.
[0010] Further, for the above-mentioned node for temporarily enhancing tension applicable to cold-formed thin-walled steel structures, the turnbuckle is arranged near the 1 / 2 height of the wall module, which is convenient for the operator to install and operate.
[0011] Further, for the above-mentioned node for temporarily enhancing tension applicable to cold-formed thin-walled steel structures, the turnbuckle is adjusted so that the two ends of the sling are tightened and a certain pre-tension is applied.
[0012] Further, for the above-mentioned node for temporarily enhancing tension applicable to cold-formed thin-walled steel structures, the lifting ring uses a lifting ring bolt in cooperation with a lifting ring nut.
[0013] From the above technical solutions, it can be seen that the present utility model has the following beneficial effects: The node for temporarily enhancing tension applicable to cold-formed thin-walled steel structures of the present utility model has a simple structure, is light in weight and easy to store. At a low cost, it avoids the risk of tensile failure at the local lifting points during the lifting process of the box module. The vertical stiffener can evenly transfer the received tension to the upper and lower flanges and the web of the floor beam, preventing the bottom guide beam from deforming and bending. The vertical stiffener does not need to be disassembled and can also bear pressure during normal use after the lifting is completed, improving the bearing capacity of the floor module. The lifting ring, turnbuckle, and sling can be removed after the lifting is completed and reused. BRIEF DESCRIPTION OF THE DRAWINGS

So that the hoisting tensile force can be transmitted to the lifting ring 3 on the bottom guide beam 11.
