Description

Technical Field

[0001] The utility model relates to the technical field of suspension point installation, in particular to a non-standard steel suspension rod structure. Background Art

[0002] At present, with the country vigorously promoting prefabricated buildings and steel structures, steel structures are developing rapidly in the field of construction. Especially in large-span structures and buildings with unique shapes, steel structures have been widely used. Compared with traditional buildings, steel structure buildings have outstanding advantages such as low resource consumption, low pollution emissions, and recyclability. Under the new trend of green development in the industry, with the increasingly stringent environmental protection policies, the rapid rise in the price of concrete structural materials has also brought new opportunities for the development of steel structures. Steel structure buildings can achieve the green, ecological, and intelligent development goals of the construction industry, and will surely become an important pillar for the sustainable development of the construction industry and even the large civil engineering industry.

[0003] In the existing steel structures, there are many secondary constructions of non-standard steel structures. During the construction, there are connections between the main and secondary beams, the main beam and the non-standard hanger, and the secondary beam and the hanger. The conventional practice is to reserve welded hanging points at the main and secondary beams. Although this practice provides convenience for the later hanger installation and has good welding integrity, for non-standard steel structures, the process equipment has many variable factors. The hanging points previously reserved at the main and secondary beams cannot be used in many cases, which either affects the installation of process pipelines or wastes steel structure materials, increases the construction period, and thus affects the project cost. For this reason, we propose a non-standard steel hanger structure. Utility Model Content

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] In order to solve the problem that the reserved welded hanging points at the main and secondary beam positions in the prior art are not suitable for installing non-standard steel structures, the following technical solutions are provided. Figure 1-6 ;

[0025] A non-standard steel hanger structure includes a main beam 1 and a secondary beam 2. An edge portion 12 is provided on the lower side of the main beam 1 and the upper side of the secondary beam 2. A square steel bar 3 is provided between the main beam 1 and the secondary beam 2. The square steel bar 3 serves to connect the main beam 1 and the secondary beam 2. The upper and lower ends of the square steel bar 3 are connected to the main beam 1 and the secondary beam 2 through a group of fixing components 4. Each group of fixing components 4 includes two flat steel plates 41 and a square steel plate 42. The flat steel plates 41 are located on both sides of the edge portion 12. The square steel plate 42 is arranged on the other side of the edge portion 12 relative to the flat steel plate 41. The flat steel plates 41 and the square steel plates 42 clamp the edge portion 12 and can adapt to edge portions 12 of different widths and thicknesses, and are flexible to install.

[0026] Four first screw holes 43 are symmetrically provided on the square steel plate 42, and two second screw holes 44 are provided on each flat steel plate 41. The first screw holes 43 and the second screw holes 44 correspond to each other. Clamping bolts 45 penetrate the first screw holes 43 and the second screw holes 44. The end of each clamping bolt 45 is threadedly matched with two nuts 46 abutting against each other. The provision of two nuts 46 can effectively avoid the problem that a single nut 46 may loosen.

[0027] The two square steel plates 42 are arranged opposite to each other, and the two ends of the square steel bar 3 are welded to the square steel plates 42 on the upper and lower sides thereof, and the welding point is located at the center of the square steel plate 42 . The extending direction of the square steel bar 3 is perpendicular to the plane where the square steel plate 42 is located.

[0028] The four sides of the end of the square steel bar 3 are respectively provided with a seat plate 5, and the horizontal edge and the vertical edge of one side of the seat plate 5 are respectively welded to the square steel plate 42 and the square steel bar 3. The seat plate 5 is provided to make the connection between the square steel bar 3 and the square steel plate 42 more stable, and ensure that the seat plate 5 is always perpendicular to the square steel bar 3 to avoid the square steel bar 3 from tilting. The welding adopts E4303 welding rod, manual arc welding, and continuous fillet weld, the weld height is K6mm, and the welding slag and burrs need to be cleaned after welding.

[0029] A positioning plate 51 is provided at the intersection of the two welding edges of the seat plate 5. The cross-section of the positioning plate 51 is an "L"-shaped structure. The extension direction of the positioning plate 51 is perpendicular to the plane where the seat plate 5 is located. The positioning plate 51 can increase the contact area between the seat plate 5 and the square steel bar 3 and the square steel plate 42. When the positioning plate 51 is attached to the square steel bar 3 and the square steel plate 42, the seat plate 5 is in a vertical state, and the seat plate 5 is not easy to tilt during welding to avoid skewness of the weld.

[0030] A reinforcement component is provided between the flat steel plate 41 and the square steel plate 42, and the reinforcement component includes a cylindrical steel bar 6 and a wedge plate 7. The cylindrical steel bar 6 is provided in the gap between the flat steel plate 41 and the square steel plate 42. The thickness of the cylindrical steel bar 6 is substantially the same as the thickness of the edge portion 12. The cylindrical steel bar 6 can balance the forces on the flat steel plate 41 and the square steel plate 42 on both sides of the clamping bolt 45, thereby preventing the flat steel plate 41 and the square steel plate 42 from being deformed after being fixed, thereby affecting the clamping of the edge portion 12. The wedge plate 7 penetrates into the gap to hold the cylindrical steel bar 6, thereby further balancing the forces on the flat steel plate 41 and the square steel plate 42 and preventing the cylindrical steel bar 6 from falling out of the gap, and preventing the flat steel plate 41 and the square steel plate 42 from falling off from the edge portion 12 under the action of long-term dynamic loads.

[0031] Limiting plates 61 are respectively provided at both ends of the cylindrical steel bar 6. The limiting plates 61 are located outside the flat steel plate 41 and the square steel plate 42 and fit closely with the flat steel plate 41 and the square steel plate 42. The limiting plates 61 can prevent the cylindrical steel bar 6 from tilting and shifting in the gap.

[0032] The specific construction process is as follows:

[0033] Step 1: Position the hanging points of the main beam 1 and the secondary beam 2 according to the process or requirements, and install the pre-assembled components after positioning;

[0034] Step 2: Place two flat steel plates 41 and one square steel plate 42 on the upper and lower sides of the edge portion 12, use clamping bolts 45 and nuts 46 to preliminarily fix them, and place a cylindrical steel bar 6 between the flat steel plate 41 and the square steel plate 42;

[0035] Step 3: Check the position of the hanging point again, tighten the clamping bolt 45 and the nut 46 after confirming it, and then embed the wedge plate 7 to limit and fix it;

[0036] Step 4: Weld the square steel plate 42 and the square steel bar 3 as a primary suspension rod;

[0037] Step 5: Add a seat plate 5 at the connection between the square steel plate 42 and the square steel bar 3. The weld height cannot be less than 4 mm.

[0038] Working principle: The lifting points of the main beam 1 and the secondary beam 2 are positioned according to the process or requirements, and the pre-assembled components are installed after positioning. Two flat steel plates 41 and a square steel plate 42 are respectively placed on the upper and lower sides of the edge 12, and they are initially fixed with clamping bolts 45 and nuts 46. A cylindrical steel bar 6 is inserted between the flat steel plate 41 and the square steel plate 42, and the position of the lifting point is checked. After confirming that it is correct, the clamping bolts 45 and nuts 46 are tightened, and then the wedge plate 7 is embedded for limiting and fixing. Finally, the square steel plate 42 and the square steel bar 3 are welded as a primary hanging rod, and a seat plate 5 is added at the connection between the square steel plate 42 and the square steel bar 3 to complete the connection between the main beam 1 and the secondary beam 2.
