Technical Field
[0001] The utility model belongs to the technical field of building engineering, and in particular relates to a thin-walled steel arc beam. Background Art
[0002] Cold-formed steel is also widely used in light steel houses as load-bearing structures, enclosure structures, accessories, etc. In house construction, cold-formed steel can be used as main load-bearing components such as steel frames, trusses, beams, columns, etc., and is also used as secondary components and enclosure structures such as roof purlins, wall frame beams and columns, keels, doors and windows, roof panels, wall panels, floor slabs, etc. In addition, the cold-formed steel-concrete composite structure that uses cold-formed steel and reinforced concrete to form composite beams, plates, and columns has also become a new research direction in the engineering field. Cold-formed thin-walled steel structural components usually include corrugated steel plates, purlins, wall beams, rigid frames, etc.
[0003] Most of the existing thin-walled steel arc beams are single arc structures. Such a structure makes the arc beam limited in its ability to bear weight, which is not conducive to bearing heavy weights. At the same time, during production, storage and transportation, it will occupy more space, increase transportation costs, and increase site and storage costs. Utility Model Content
[0004] The purpose of the utility model is to provide a thin-walled steel arc beam to solve the problems mentioned in the background technology.
[0005] In order to achieve the above technical purpose, the technical solution adopted by the utility model is as follows:

[0008] The outer sides of the two groups of latches are both provided with downwardly facing inclined surfaces.
[0009] Two triangular pads symmetrically distributed on the left and right are installed between the two ends of each group of folded arc beams and the cross beam.
[0010] A mounting groove matching the folded arc beam is provided in the middle of the triangular pad, and the folded arc beam is fixedly connected to the triangular pad by bolts.
[0011] There are multiple groups of rotating shafts on the side surfaces of each group of folded arc beams, which are evenly distributed up and down.
[0012] A plurality of triangular hollows are evenly arranged in the middle of the folded arc beam.
[0013] Two groups of folding arc beams symmetrically distributed front and back can increase the weight bearing capacity of the arc beam, the crossbeam can strengthen the bottom of the arc beam, enhance its compressive bending strength, and improve its service life. At the same time, the foldable folding arc beam can reduce the space occupied by the arc beam during production, storage and transportation, which can effectively reduce the storage cost and transportation cost. The cooperation of the handle and the latch makes the installation and disassembly of the pallet assembly more convenient, and it is convenient to lift the pallet assembly.

[0022] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.
[0023] like Figure 1-6 As shown, a thin-walled steel arc beam comprises a cross beam 1, two groups of folding arc beams 2 are fixed on the upper ends of both sides of the cross beam 1, the two groups of folding arc beams 2 are symmetrically distributed front to back, the folding arc beam 2 comprises two half beams 15 distributed left and right, a rotating shaft 3 is vertically installed in the middle of the two half beams 15, a card slot 4 is opened on the side where the folding arc beams 2 are close to each other, and a card plate assembly for connecting and fixing the two groups of folding arc beams 2 is installed inside the card slot 4.
[0024] During installation, the utility model can fold a single folding arc beam 2 from the middle in one direction. When the folding arc beam 2 needs to be installed, the two groups of folding arc beams 2 are placed with the rotation axes 3 facing outwards respectively, and the card assembly is installed on the inner side of the card slot 4. Since the folding arc beam 2 can only be folded in one direction, the card assembly is arranged between the two folding arc beams 2 to fix it. The two groups of folding arc beams 2 symmetrically distributed front and back can increase the weight-bearing capacity of the arc beam, and the cross beam 1 can strengthen the bottom of the arc beam, enhance its compressive bending strength, and improve its service life. At the same time, the foldable folding arc beam 2 can reduce the space occupied by the arc beam during production, storage and transportation, and can effectively reduce storage costs and transportation costs.
[0025] A lock hole 5 is also provided in the middle of the folding arc beam 2, and the cardboard assembly includes a cardboard bracket 6, and two groups of latches 7 are installed on the front and back sides of the inner side of the cardboard bracket 6. The latches 7 are slidably connected to the cardboard bracket 6 front and back, and the latches 7 match the lock hole 5. A spring 8 is installed on the side close to the two groups of latches 7, and a handle 9 is transmission-connected to the upper side of the latch 7, and the uppermost side of the handle 9 is lower than the highest point of the folding arc beam 2.
[0026] When the pallet assembly is in use, the staff moves the two handles 9 together and places the pallet bracket 6 on the inner side of the slot 4. After the pallet bracket 6 reaches the specified position, the spring 8 allows the latch 7 to be inserted into the inner side of the lock hole 5 to fix it. When the curved beam needs to be removed, it is only necessary to move the two handles 9 together again. After the latch 7 leaves the lock hole 5, the entire pallet assembly can be directly lifted up for removal. The cooperation between the handles 9 and the latch 7 makes the installation and disassembly of the pallet assembly more convenient, and it is also convenient to lift the pallet assembly. The design of the handle 9 being lower than the highest point of the folded curved beam 2 can avoid interference with the objects supported by the upper side of the curved beam.
[0027] The outer sides of the two groups of latches 7 are both provided with downwardly facing inclined surfaces 10 .
[0028] The inclined surface 10 on the lower side of the latch 7 can drive the wrench to automatically move toward the middle when the card assembly is installed, thereby improving the convenience of use.
[0029] Two triangular pads 11 symmetrically distributed on the left and right are installed between the two ends of each group of folded arc beams 2 and the cross beam 1 .
[0030] A mounting groove 13 matching the folded arc beam 2 is provided in the middle of the triangular pad 11 , and the folded arc beam 2 is fixedly connected to the triangular pad 11 by bolts 14 .
[0031] The triangular pad 11 makes the force direction of the fixing screw and the arc beam perpendicular, which can improve the connection strength with the triangular pad 11 and reduce the bearing capacity of the bolt 14, extending the service life. The installation groove 13 can facilitate the installation of the folding arc beam 2 and improve the convenience of use.
[0032] There are multiple groups of rotating shafts 3 on the side of each group of folded arc beams 2, and they are evenly distributed up and down.
[0033] The multiple groups of rotating shafts 3 can guarantee the bearing capacity of the folding part of the folded arc beam 2 to the maximum extent, ensure the overall structural strength, and improve the overall reliability of the arc beam.
[0034] A plurality of triangular hollows 13 are evenly formed in the middle of the folded arc beam 2 .
[0035] The design of the triangular hollow 13 can reduce the use of steel materials and reduce production costs, while also improving the structural strength of the arc beam and improving the load-bearing capacity of the arc beam.
[0036] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the technology may modify or change the above embodiments without violating the spirit and scope of the present invention. Therefore, all equivalent modifications or changes made by those with ordinary knowledge in the relevant technical field without departing from the spirit and technical ideas disclosed in the present invention shall still be covered by the claims of the present invention.
