Description

Technical Field

[0001] The invention relates to the technical field of steel structures, in particular to a steel structure support beam which is easy to transport. Background Art

[0002] Steel structure support beams are an important component of steel structure building components. There are two types of existing steel structure support beams. The most common one is an integrated structure, which is transported as a whole to the construction site and used directly. This type of steel structure support beam occupies a large transportation space due to its large structure, and the number of beams transported by a single transport vehicle is limited. The other is an assembled steel structure support beam, which is transported after being disassembled. It occupies little space during transportation and is easy to transport. However, it takes a certain amount of installation time after arriving at the site, and the simple bolt and nut installation is not only inefficient but also has a certain risk of loosening.

[0003] Therefore, how to provide a steel structure support beam that is easy to transport, can reduce space occupancy during transportation, increase the number of single-time deliveries by a single transport vehicle, and can be quickly assembled on site, with a stable structure and fasteners that are not easy to loosen after assembly, is a technical problem that needs to be urgently solved by technical personnel in this field. Summary of the invention

[0004] The purpose of the present invention is to provide a steel structure support beam that is easy to transport, overcome the shortcomings of the aforementioned prior art, reduce space occupancy during transportation, increase the single-time delivery quantity of a single transport vehicle, and can be quickly assembled on site. After assembly, the structure is stable and fasteners are not easy to loosen.

[0005] The technical solution adopted by the present invention to solve the technical problem is:

[0006] A steel structure support beam that is easy to transport, comprising an upper beam, a lower beam, and an X-shaped support beam spaced between the upper beam and the lower beam, wherein:

[0007] The X-shaped support beam comprises a first support beam and a second support beam, the first support beam is a piece of V-shaped steel, the second support beam is two pieces of V-shaped steel arranged at intervals, the tip of the V-shaped steel of the first support beam of the same X-shaped support beam is inserted between the tips of the two pieces of V-shaped steel of the second support beam, the tip of the V-shaped steel of the first support beam of the same X-shaped support beam and the tips of the two pieces of V-shaped steel of the second support beam are connected by an adjustable fastener, by adjusting the adjustable fastener, the first support beam and the second support beam can be connected to form an X-shaped support beam, and the connection between the first support beam and the second support beam can be released, the first support beam is inserted between the two pieces of V-shaped steel of the second support beam, so that the first support beam and the second support beam are staggered and crossed, the overall structure is compressed to half of the original volume, and the single-time conveying quantity of a single transport vehicle is increased;

[0008] The adjustable fastener comprises a threaded rod, a threaded tube and a limiting ring, the length of the threaded rod being less than or equal to the thickness of the first support beam, the two end faces of the threaded rod being provided with slots matching the screwing workpiece, a limiting ring coaxial therewith being fixed to the middle part of the threaded rod, the threads on the threaded rods on both sides of the limiting ring being in opposite directions, the threaded rods on both sides of the limiting ring being threadedly connected with threaded tubes, the outer walls of the threaded tubes being also provided with threads, and the threads on the outer walls of the two threaded tubes being in opposite directions, a first threaded hole being provided at the tip of the V-shaped steel of the first support beam, a limiting groove being provided at the middle part of the first threaded hole, the limiting ring being installed in the limiting groove, the threads on the first threaded holes on both sides of the limiting groove respectively matching the threads on the outer walls of the corresponding threaded tubes, the tips of the two V-shaped steels of the second support beam being provided with second threaded holes, the thread directions of the second threaded holes being consistent with the thread directions of the first threaded holes corresponding to their positions;

[0009] When the adjustable fastener is in use, the threaded rod is screwed by a screwdriver, a hexagonal wrench or other tools, and the threaded rod rotates. However, under the restriction of the limit ring and the limit groove, the threaded rod can only rotate circumferentially and cannot move circumferentially. This causes the two threaded tubes whose inner wall is threadedly connected to the threaded rod and whose outer wall is threadedly connected to the first threaded hole to respectively produce axial rotational movement outward, and a part of the threaded tube is screwed into the second threaded hole to connect the second support beam with the first support beam. Since the adjustment structure of the adjustable fastener is located at both ends of the threaded rod, the threaded rod is difficult to adjust after the screwing tool is withdrawn. Therefore, the steel structure support beam that is easy to transport of the present invention can not only be quickly assembled on site, but also has a stable structure after assembly and the fasteners are not easy to loosen, and the assembly efficiency, stability after assembly and safety after assembly are all excellent.

[0010] Furthermore, among adjacent X-shaped support beams, the first support beam of one X-shaped support beam is connected to the upper beam, and the second support beam is connected to the lower beam, and the first support beam of the other X-shaped support beam is connected to the lower beam, and the second support beam is connected to the upper beam. This staggered arrangement greatly improves the structural strength of the entire steel structure support beam, which is easy to transport, both during transportation and during use after the entire assembly is completed.

[0011] Furthermore, among the three adjacent X-shaped support beams, the open ends of the first support beam located in the middle of the X-shaped support beam respectively extend into the inner cavities of the open ends of the second support beams located on both sides of the X-shaped support beams and are welded to the second support beams, greatly improving the structural strength.

[0012] Furthermore, the adjustable fastener also includes an end locking member, which includes a first screw, a second screw and a locking screw crown, the first screw is coaxially connected with the second screw, the first screw matches with the thread of the inner wall of the threaded tube, the second screw matches with the thread of the inner wall of the second threaded hole, and the locking screw crown is arranged at the outer end of the second screw. The sum of the lengths of the first screw and the second screw is equal to or less than the thickness of a single V-shaped steel in the second support beam, and the end locking member is selectively installed and can be installed only on a few X-shaped support beams, for example, only on the X-shaped support beams at both ends of the upper beam and the lower beam, to further ensure the anti-loosening effect.

[0013] The beneficial effects of the present invention are as follows: compared with the prior art, the steel structure support beam of the present invention, which is easy to transport, has the following advantages: (1) by adjusting the adjustable fastener, the first support beam and the second support beam can be connected to form an X-shaped support beam, and the connection between the first support beam and the second support beam can be released, and the first support beam can be inserted between the two V-shaped steels of the second support beam, so that the first support beam and the second support beam are staggered and crossed, and the overall structure is compressed to half of the original volume, thereby increasing the single-time delivery quantity of a single transport vehicle; (2) by screwing the threaded rod with a tool such as a screwdriver or a hexagonal wrench, the threaded rod rotates, but the limit ring and the limit Due to the limitation of the positioning groove, the threaded rod can only rotate circumferentially but not move circumferentially, which makes the two threaded tubes whose inner wall is threadedly connected to the threaded rod and whose outer wall is threadedly connected to the first threaded hole respectively produce axial rotational movement outward, and the threaded tube is partially screwed into the second threaded hole to connect the second support beam with the first support beam. Since the adjustment structure of the adjustable fastener is located at both ends of the threaded rod, the threaded rod is difficult to adjust after the screwing tool is withdrawn. Therefore, the steel structure support beam that is easy to transport of the present invention can not only be quickly assembled on site, but also has a stable structure after assembly and the fasteners are not easy to loosen, and the assembly efficiency, stability after assembly and safety after assembly are all excellent.

DETAILED DESCRIPTION

[0021] To make the purpose, technical solution and advantages of the embodiments of the present invention more clear, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0022] like Figure 1-6 In the embodiment shown, a steel structure support beam that is easy to transport includes an upper beam 1, a lower beam 2, and an X-shaped support beam spaced between the upper beam 1 and the lower beam 2, wherein:

[0023] The X-shaped support beam comprises a first support beam 3 and a second support beam 4, the first support beam 3 is a V-shaped steel, the second support beam 4 is two V-shaped steels arranged at intervals, the V-shaped steel tip of the first support beam 3 of the same X-shaped support beam is inserted between the two V-shaped steel tips of the second support beam 4, the V-shaped steel tip of the first support beam 3 of the same X-shaped support beam and the two V-shaped steel tips of the second support beam 4 are connected by an adjustable fastener 5, by adjusting the adjustable fastener 5, the first support beam 3 and the second support beam 4 can be connected to form an X-shaped support beam, and the connection between the first support beam 3 and the second support beam 4 can be released, the first support beam 3 is inserted between the two V-shaped steels of the second support beam 4, so that the first support beam 3 and the second support beam 4 are staggered and crossed, the overall structure is compressed to half of the original volume, and the single conveying quantity of a single transport vehicle is increased;

[0024] The adjustable fastener 5 includes a threaded rod 501, a threaded tube 502 and a limiting ring 503. The length of the threaded rod 501 is less than or equal to the thickness of the first support beam 3. The two end faces of the threaded rod 501 are provided with slots 504 that match the screwed workpiece. A limiting ring 503 coaxial with the threaded rod 501 is fixed in the middle part. The threads on the threaded rods 501 on both sides of the limiting ring 503 are in opposite directions. The threaded rods 501 on both sides of the limiting ring 503 are threadedly connected with the threaded tube 502. The outer wall of the threaded tube 502 is also provided with a threaded The threads on the outer walls of the two threaded tubes 502 are in opposite directions. The tip of the V-shaped steel of the first support beam 3 is provided with a first threaded hole 6. A limiting groove 7 is provided in the middle of the first threaded hole 6. The limiting ring 503 is installed in the limiting groove 7. The threads on the first threaded holes 6 on both sides of the limiting groove 7 are respectively matched with the threads on the outer walls of the corresponding threaded tubes 502. The tips of the two V-shaped steels of the second support beam 4 are both provided with second threaded holes 8. The thread direction of the second threaded hole 8 is consistent with the thread direction of the first threaded hole 6 corresponding to its position.

[0025] When the adjustable fastener 5 is in use, the threaded rod 501 is screwed by a tool such as a screwdriver or a hexagonal wrench, and the threaded rod 501 rotates. However, under the restriction of the limit ring 503 and the limit groove 7, the threaded rod 501 can only rotate circumferentially but not move circumferentially. This causes the two threaded tubes 502 whose inner wall is threadedly connected to the threaded rod 501 and whose outer wall is threadedly connected to the first threaded hole 6 to respectively produce axial rotational movement outward, and the threaded tube 502 is partially screwed into the second threaded hole 8 to connect the second support beam 4 with the first support beam 3. Since the adjustment structure of the adjustable fastener 5 is located at both ends of the threaded rod 501, when the screwing tool is withdrawn, the threaded rod 501 is difficult to adjust. Therefore, the steel structure support beam that is easy to transport of the present invention can not only be quickly assembled on site, but also has a stable structure after assembly and the fasteners are not easy to loosen, and the assembly efficiency, stability after assembly and safety after assembly are all excellent.

[0026] In this embodiment, among the adjacent X-shaped support beams, the first support beam 3 of one X-shaped support beam is connected to the upper beam 1, and the second support beam 4 is connected to the lower beam 2, and the first support beam 3 of the other X-shaped support beam is connected to the lower beam, and the second support beam 4 is connected to the upper beam 1. This staggered arrangement greatly improves the structural strength of the entire steel structure support beam that is easy to transport both during transportation and during use after the entire assembly is completed; among the three adjacent X-shaped support beams, the open ends of the first support beam 3 of the X-shaped support beam located in the middle respectively extend into the open end inner cavities of the second support beams 4 of the X-shaped support beams located on both sides and are welded to the second support beams 4, which greatly improves the structural strength.

[0027] In this embodiment, the adjustable fastener 5 also includes an end locking member 505, which includes a first screw rod 5051, a second screw rod 5052 and a locking screw crown 5053. The first screw rod 5051 is coaxially connected with the second screw rod 5052, the first screw rod 5051 matches with the thread of the inner wall of the threaded tube 502, the second screw rod 5052 matches with the thread of the inner wall of the second threaded hole 8, and the locking screw crown 5053 is arranged at the outer end of the second screw rod 5052. The sum of the lengths of the first screw rod 5051 and the second screw rod 5052 is equal to or less than the thickness of a single V-shaped steel in the second support beam 4. The end locking member 505 is selectively installed and can be installed only on several X-shaped support beams. For example, in this embodiment, it is only installed on the X-shaped support beams at both ends of the upper beam 1 and the lower beam 2, which further ensures the anti-loosening effect.

[0028] Working principle:

[0029] In the transport state: by adjusting the adjustable fastener 5, the threaded tube 502 is located inside the corresponding first threaded hole 6, the connection between the first support beam 3 and the second support beam 4 is released, and the first support beam 3 is inserted between the two V-shaped steels of the second support beam 4, so that the first support beam 3 and the second support beam 4 are staggered and crossed, and the overall structure is compressed to half of the original volume, thereby increasing the single-time transportation quantity of a single transport vehicle.

[0030] During on-site assembly, the threaded rod 501 is screwed with a screwdriver, a hexagonal wrench or other tools, and the threaded rod 501 rotates. However, under the restriction of the limit ring 503 and the limit groove 7, the threaded rod 501 can only rotate circumferentially but not move circumferentially. This causes the two threaded tubes 502 whose inner wall is threadedly connected to the threaded rod 501 and whose outer wall is threadedly connected to the first threaded hole 6 to respectively produce axial rotational movement outward, and a portion of the threaded tube 502 is screwed into the second threaded hole 8 to connect the second support beam 4 with the first support beam 3, and then the end locking parts 505 are installed on the X-shaped support beams at both ends.

[0031] The above-mentioned specific implementations are only specific cases of the present invention. The patent protection scope of the present invention includes but is not limited to the product form and style of the above-mentioned specific implementations. Any appropriate changes or modifications made to them by ordinary technicians in the technical field that conform to the claims of the present invention shall fall within the patent protection scope of the present invention.
