Description

Technical Field

[0001] The utility model relates to the technical field of building construction scaffolds, and particularly to an assembled truss structure. Background Art

[0002] Truss: A structure made of rods connected to each other at both ends with hinges. A truss is a plane or space structure composed of straight rods, generally with triangular units. Truss rods mainly bear axial tension or pressure, so as to make full use of the strength of the material. When the span is large, it can save materials, reduce deadweight and increase rigidity compared with solid beams.

[0003] Common trusses are mostly integral. The transportation cost of integral trusses is high and requires a large transportation space. As a result, some assembled trusses are derived, which are convenient for assembly and transportation and reduce costs. However, some assembled brackets are mostly assembled with bolts and other parts. Unassembled screws and other parts are easily damaged during storage and transportation. Screws with accidentally worn threads can easily reduce the safety of assembled trusses.

[0004] In order to solve the above problems, this application proposes an assembled truss structure. Summary of the invention

[0005] The utility model aims at the technical problems existing in the prior art and provides an assembled truss structure.

[0006] The technical solution of the utility model for solving the above-mentioned technical problems is as follows: an assembled truss structure comprises a lower base, the top of the lower base is fixedly connected with a load-bearing straight rod, the outer surface of the load-bearing straight rod is welded with an inclined straight rod, the top of the load-bearing straight rod is fixedly connected with an upper base, the top of the upper base is provided with an isolation groove, the inner surface of the upper base is rotatably connected with a partition, the bottom of the lower base is provided with a positioning hole, the inner surface of the lower base is provided with a threaded hole, the positioning hole is connected with the threaded hole, the outer surface of the partition is rotatably connected with a positioning round block, the side of the positioning round block away from the partition is fixedly connected with a threaded rod, the outer surface of the upper base is rotatably connected with an adjusting block, the outer surface of the adjusting block is installed with a limiting telescopic rod, the outer surface of the limiting telescopic rod is wound with a limiting spring, the telescopic end of the limiting telescopic rod is fixedly connected with a limiting plate, and the bottom of the limiting plate is in conflict with the outer surface of the partition.

[0007] The threaded rod matches the threaded hole, the radius of the positioning block is equal to the radius of the positioning hole, the depth of the positioning hole is less than the height of the positioning block, and by setting the thickness of the positioning block, when the upper and lower adjacent lower bases and upper bases are fixed to each other, the higher positioning block is not completely inserted into the lower base, and the operator can remove and replace the adjacent lower base and upper base by rotating the exposed positioning block.

[0008] The outer surface of the load-bearing straight rod is fixedly connected to a horizontal straight rod, the outer surface of the horizontal straight rod is movably sleeved with a threaded sleeve, the inner surface of the threaded sleeve is threadedly connected to a detachable straight rod, and by arranging the horizontal straight rod, the threaded sleeve and the detachable straight rod, when the threaded sleeve is aligned with and in contact with the horizontal straight rod, the detachable straight rod and the horizontal straight rod can be fixed to each other by rotating the threaded sleeve, so that the detachable straight rod that is accidentally damaged can be quickly removed and replaced.

[0009] A limit slot is provided on the outer surface of the upper base, and the limit slot matches the limit plate. By setting the limit slot, the rotation of the adjustment block can change the position of the limit plate. When the limit plate is inserted into the limit slot under force, the movement of the limit plate is restricted, so as to avoid accidental movement of the limit plate due to external force interference.

[0010] A storage hole is provided on the outer surface of the lower base, and the radius of the storage hole is equal to the radius of the positioning hole. A dustproof plug is movably inserted into the inner cavity of the lower base, and the dustproof plug is located in the storage hole. By providing the storage hole, the dustproof plug and the load-bearing straight rod lower base, the dustproof plug can be inserted into the positioning hole below the lower base again after being forced out of the storage hole, thereby conveniently blocking the positioning hole and minimizing the risk of debris entering the threaded hole to cause thread damage.

[0011] The beneficial effects of this utility model are:

[0012] The assembled truss structure can release the flipping restriction of the partition by pulling the limit plate upwards and rotating the adjustment block. When the positioning circle on the surface of the partition is exposed from the inside of the isolation groove, the adjacent lower base and upper base can be relatively fixed by entering the threaded hole through the threaded rod, which is convenient for rapid disassembly and assembly of the lower base and the upper base, while trying to avoid accidental collision and damage of the exposed threaded rod, which may cause unstable connection between the lower base and the upper base.

Any embodiment described as "for example" in the present application is not necessarily to be interpreted as being more preferred or advantageous than other embodiments. In order to enable any technician in the field to implement and use the present utility, the following description is given. In the following description, details are listed for the purpose of explanation. It should be understood that a person of ordinary skill in the art can recognize that the present utility can be implemented without using these specific details. In other examples, well-known structures and processes will not be elaborated in detail to avoid unnecessary details that make the description of the present utility obscure. Therefore, the present utility is not intended to be limited to the embodiments shown, but is consistent with the widest range of principles and features disclosed in the present application.

[0022] Reference Figure 1-2 An assembled truss structure includes a lower base 1, a load-bearing straight rod 2 is fixedly connected to the top of the lower base 1, an inclined straight rod 3 is welded to the outer surface of the load-bearing straight rod 2, an upper base 4 is fixedly connected to the top of the load-bearing straight rod 2, the lower base 1 is equal to the upper base 4 in height, and the lower base 1 and the upper base 4 are equal in horizontal cross-sectional area.

[0023] Reference Figure 1-3An isolation groove 5 is provided on the top of the upper base 4, and a partition 6 is rotatably connected to the inner surface of the upper base 4. A positioning hole 7 is provided at the bottom of the lower base 1, and a threaded hole 8 is provided on the inner surface of the lower base 1. The positioning hole 7 is connected to the threaded hole 8. The outer surface of the partition 6 is rotatably connected to a positioning block 9. A threaded rod 10 is fixedly connected to the side of the positioning block 9 away from the partition 6. The threaded rod 10 matches the threaded hole 8, and the radius of the positioning block 9 is equal to the radius of the positioning hole 7. When the partition 6 is rotated one hundred and eighty degrees by force, the positioning block 9 and the threaded rod 10 on the surface of the partition 6 are forced to separate from the isolation groove 5, and then the operator can drive the threaded rod 10 to insert into the threaded hole 8 inside the adjacent lower base 1 by rotating the positioning block 9, which is convenient for assembling and splicing trusses according to actual conditions and for quickly replacing partially damaged trusses.

[0024] Reference Figure 1 The outer surface of the upper base 4 is rotatably connected with an adjusting block 11, and a limiting telescopic rod 12 is installed on the outer surface of the adjusting block 11. The outer surface of the limiting telescopic rod 12 is wound with a limiting spring 13, and the telescopic end of the limiting telescopic rod 12 is fixedly connected to a limiting plate 14. The bottom of the limiting plate 14 is in contact with the outer surface of the partition 6. The rotation of the adjusting block 11 can drive the limiting plate 14 to rotate. When the limiting plate 14 is located directly above the partition 6, the limiting plate 14 quickly presses against the center of the top of the partition 6 under the action of the limiting telescopic rod 12 and the limiting spring 13. The limiting plate 14 presses against the partition 6 to limit the flipping of the partition 6.

[0025] Reference Figure 1-3 The depth of the positioning hole 7 is smaller than the height of the positioning block 9. After the two adjacent lower bases 1 and upper bases 4 are fixed to each other, part of the positioning block 9 is exposed. The operator can quickly separate the lower base 1 from the adjacent upper base 4 by rotating the exposed positioning block 9.

[0026] Reference Figure 1 and Figure 4 The outer surface of the load-bearing straight rod 2 is fixedly connected with a horizontal straight rod 15, and the outer surface of the horizontal straight rod 15 is movably sleeved with a threaded sleeve 16, and the inner surface of the threaded sleeve 16 is threadedly connected with a detachable straight rod 17. When the detachable straight rod 17 is aligned with and in contact with two symmetrically distributed horizontal straight rods 15, the operator can fix the position of the detachable straight rod 17 by rotating the threaded sleeve 16, which is convenient for the operator to quickly remove and replace the damaged detachable straight rod 17.

[0027] Reference Figure 1-2A limit slot 18 is provided on the outer surface of the upper base 4, and the limit slot 18 matches the limit plate 14. The rotation of the adjustment block 11 can adjust the position of the limit plate 14. When the limit plate 14 is rotated ninety degrees by force, the limit plate 14 is quickly inserted into the limit slot 18 by the force of the limit telescopic rod 12 and the limit spring 13, and the movement of the limit plate 14 is restricted, so as to avoid accidental movement of the limit plate 14 due to external force interference.

[0028] Reference Figure 2 A storage hole 19 is provided on the outer surface of the lower base 1, and the radius of the storage hole 19 is equal to the radius of the positioning hole 7. A dustproof plug 20 is movably inserted into the inner cavity of the lower base 1. The dustproof plug 20 is made of rubber and is located in the storage hole 19. When the dustproof plug 20 passes through the positioning hole 7 and is inserted into the lower base 1, impurities such as small gravel from the outside cannot enter the threaded hole 8 and cause thread damage. At the same time, when the lower base 1 needs to be connected to the adjacent upper base 4, the operator can insert excess dustproof plugs 20 into the storage hole 19.

[0029] Working principle:

[0030] For the assembled truss structure, first, the operator pulls the limit plate 14 upwards. When the limit plate 14 is completely separated from the threaded sleeve 16, the adjustment block 11 is rotated to release the flipping restriction of the partition 6. The partition 6 is flipped 180 degrees under force to drive the positioning circle 9 and the threaded rod 10 on the surface to be exposed from the inside of the isolation groove 5. After the positioning circle 9 and the threaded rod 10 are completely exposed, the upper and lower adjacent lower base 1 and upper base 4 can be fixed by the threaded rod 10 entering the threaded hole 8, which is convenient for the operator to quickly disassemble and assemble the truss according to the actual situation, and at the same time, it is avoided as much as possible that the exposed threaded rod 10 is accidentally bumped and damaged, resulting in an unstable connection between the lower base 1 and the upper base 4.

Therefore, the appended claims are intended to be interpreted as including the preferred embodiments and all changes and modifications falling within the scope of the present invention.

[0032] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention.
