Description

Technical Field

[0001] The utility model relates to the technical field of steel structure trusses, and specifically relates to a building steel structure truss which is convenient for assembly. Background Art

[0002] A steel structure is a structure composed of steel materials and is one of the main building structure types. The structure is mainly composed of steel beams, steel columns, steel trusses and other components made of sections and steel plates, and rust removal and rust prevention processes such as silanization, pure manganese phosphating, water washing and drying, and galvanizing are adopted. Welds, bolts or rivets are usually used to connect between components or parts. Because of its light self-weight and simple construction, it is widely used in large factories, stadiums, super high-rise buildings and other fields. At present, when connecting and fixing two trusses, welding or screw fixing is generally adopted. Such fixing methods can play a fixing role in a short time, but with long-term use and the influence of external rainwater, it is easy to cause rust and looseness at the connection, and thus there is a certain danger.

[0003] After retrieval, the Chinese patent publication number is CN213299333U, which discloses a project management visual kanban. In this patent, by inserting one end of a solid round rod into the inner cavity of an installation inner slot, after the threaded rod and the internal threaded groove are threadedly connected, when the extension rod is inserted into the inner cavity of the inner slot, the outer wall of the inner slot will be inserted into the inner cavity of the embedding slot, and the through slot and the corresponding slot are fixedly installed by using fixing nails. The threaded connection between the threaded rod and the internal threaded groove and the fixation of the fixing nails can improve the connection stability between the truss and the solid round rod;

[0004] However, when the above device is used, as can be seen from the drawings and specifications of this patent, the first truss, the second truss and the connection assembly are rotationally connected by threads. Rotation is required both for disassembly and installation. And when rusting and other situations occur after long-term use, the disassembly and installation of the whole device are more cumbersome compared with the traditional plug-in assembly method. At the same time, the connection assembly can only install the first truss and the second truss in parallel, and the height of a single truss is fixed, so that the truss cannot be installed perpendicular to the connecting piece, resulting in poor practicability of the whole device after installation. Content of the Utility Model

[0005] The utility model provides a building steel structure truss which is convenient for assembly, having the advantages of rapid assembly or disassembly and meeting different height or width environments, and improving the overall practicability, and solving the problems of cumbersome assembly or disassembly easily affected by external forces and poor practicability of the whole device.

[0006] The technical solution of the present utility model is as follows: A building steel structure truss that is convenient for assembly, including a base block. A slot is provided on the front side of the base block. A plug rod is detachably installed in the inner cavity of the slot. A hook ring is fixedly installed on the front side of the plug rod. A plurality of mounting blocks are fixedly installed on the outer surface of the base block. An installation groove is provided on the right side of the mounting block. A circular hole is provided in the middle of the rear side of the mounting block. A strip-shaped groove is provided in the middle of the front side of the mounting block. An inclined surface groove is provided on the left side of the strip-shaped groove. A truss rod is detachably installed in the inner cavity of the installation groove. Threaded holes are provided on the left and right sides of the rear side of the truss rod. Bolts are detachably installed in the inner cavities of the threaded holes. A polygonal hole is provided on the rear side of the bolts.

[0007] Preferably, the rear side of the plug rod is designed to be pointed. The length of the combination of the hook ring and the plug rod is greater than the depth of the inner cavity of the slot. Thus, when in use, by using the length of the combination of the hook ring and the plug rod, it is convenient to quickly take out the plug rod from the inner cavity of the slot or install the plug rod into the inner cavity of the slot when in use.

[0008] Preferably, the plurality of mounting blocks are respectively welded on the left and right sides, the top surface and the rear surface. The mounting blocks and the base block are both made of steel. Thus, when in use, by using the steel materials of the mounting blocks and the base block, it is convenient to assemble the mounting blocks and the base block with the steel truss rods.

[0009] Preferably, the shape of the outer surface of the truss rod matches the shape of the inner cavity of the installation groove. The position of the circular hole in the installation groove matches the position where the threaded hole is opened on the outer surface of the truss rod. Thus, when in use, after the truss rod is installed into the inner cavity of the installation groove, the bolt passes through the circular hole and enters the inner cavity of the threaded hole on one side of the truss rod, thereby fixing the mounting block and the truss rod.

[0010] Preferably, the bolt is divided into two parts: a screw rod and a nut. Threads that match the inner wall shape of the threaded hole are provided on the outer surface of the screw rod. The cross-sectional shape of the nut is larger than the cross-sectional shape of the screw rod. The cross-sectional shape of the screw rod matches the shape of the inner cavity of the circular hole. Thus, when in use, the screw rod part on one side of the bolt passes through the circular hole and rotates into the inner cavity of the threaded hole, and cooperates with the nut to fix the combined truss rod and mounting block.

[0011] Preferably, the strip-shaped groove penetrates through the front outer surface and the front inner wall of the mounting block. The strip-shaped groove communicates with the inclined surface groove on the outer surface of the same mounting block. The length of the inner cavity of the strip-shaped groove matches the length of the inner cavity of the installation groove. The width of the inner cavity of the strip-shaped groove is greater than the width of the plug rod. Thus, when in use, the plug rod can move smoothly left and right in the inner cavity of the strip-shaped groove, which is convenient for separating the truss rod from the installation groove.

[0012] Preferably, the bottom of the rear side of the inclined groove is located in the inner cavity of the installation groove, and the rear side of the inclined groove is located on the rear side of the strip groove, so that when the truss is disassembled in use, the pointed part of the insertion rod is inserted through the inclined groove, that is, the pointed part of the insertion rod extends into the connection between the truss and the inner cavity of the installation groove, thereby separating and shaking the position of the truss in the inner cavity of the installation groove. As the insertion rod is continuously inserted and shaken, the truss is easily removed from the inner cavity of the installation groove.

[0013] Preferably, the polygonal hole does not penetrate the nut on one side of the bolt, and the circular hole is mostly opened on the inner side of the assembled device, so that when in use, the polygonal tool rod is inserted into the inner cavity of the polygonal hole to rotate the bolt, thereby fixing the truss and the mounting block.

[0014] The working principle and beneficial effects of the utility model are:

[0015] The easy-to-assemble building steel structure truss is used in conjunction with a strip groove structure and an inclined groove structure. When working, the shape of the outer surface of the truss rod and the shape of the inner cavity of the installation groove are used to quickly insert the truss rod into the inner cavity of the installation groove, and then the bolt is rotated through the round hole into the inner cavity of the threaded hole to fix the installed truss rod and the installation block. When disassembly is required, the insertion rod is taken out and inserted along the inclined groove, so that the truss rod swings in the inner cavity of the installation groove, which facilitates the separation of the truss rod from the installation groove, thereby achieving rapid assembly or disassembly and meeting different height or width environments, thereby improving the overall practicality.

[0023] Next, in combination with the embodiments of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present invention.

[0024] Please refer to Figures 1 to 5As shown in the figure, a building steel structure truss that is convenient for assembly includes a base block 1. A slot 2 is provided on the front side of the base block 1. A plug rod 3 is detachably installed in the inner cavity of the slot 2. The rear side of the plug rod 3 is designed to be pointed. The combined length of the hook ring 4 and the plug rod 3 is greater than the depth of the inner cavity of the slot 2. Therefore, during use, by using the combined length of the hook ring 4 and the plug rod 3, it is convenient to quickly take out the plug rod 3 from the inner cavity of the slot 2 or install the plug rod 3 into the inner cavity of the slot 2 through the hook ring 4 during use. A hook ring 4 is fixedly installed on the front side of the plug rod 3. A plurality of mounting blocks 5 are fixedly installed on the outer surface of the base block 1. The plurality of mounting blocks 5 are respectively welded on the left and right sides, the top surface, and the rear surface. Both the mounting blocks 5 and the base block 1 are made of steel. Therefore, during use, by using the steel materials of the mounting blocks 5 and the base block 1, it is convenient to assemble the mounting blocks 5 and the base block 1 with the steel truss rod 10. An installation groove 6 is provided on the right side of the mounting block 5. A round hole 7 is provided in the middle of the rear side of the mounting block 5. A strip-shaped groove 8 is provided in the middle of the front side of the mounting block 5. The strip-shaped groove 8 runs through the front outer surface and the front inner wall of the mounting block 5. The strip-shaped groove 8 communicates with the inclined surface groove 9 on the outer surface of the same mounting block 5. The length of the inner cavity of the strip-shaped groove 8 matches the length of the inner cavity of the installation groove 6. The width of the inner cavity of the strip-shaped groove 8 is greater than the width of the plug rod 3. Therefore, during use, the plug rod 3 can smoothly move left and right in the inner cavity of the strip-shaped groove 8, which is convenient for the truss rod 10 to be separated from the installation groove 6. An inclined surface groove 9 is provided on the left side of the strip-shaped groove 8. A truss rod 10 is detachably installed in the inner cavity of the installation groove 6. The shape of the outer surface of the truss rod 10 matches the shape of the inner cavity of the installation groove 6. The position of the round hole 7 in the installation groove 6 matches the position where the threaded hole 11 is provided on the outer surface of the truss rod 10. Therefore, during use, after the truss rod 10 is installed into the inner cavity of the installation groove 6, the bolt 12 passes through the round hole 7 and enters the inner cavity of the threaded hole 11 on one side of the truss rod 10, thereby fixing the mounting block 5 and the truss rod 10. The bottom of the rear side of the inclined surface groove 9 is located in the inner cavity of the installation groove 6, and the rear side of the inclined surface groove 9 is located at the rear side of the strip-shaped groove 8. Therefore, during use, when the truss rod 10 is disassembled, the pointed part of the plug rod 3 is inserted through the inclined surface groove 9, that is, the pointed part of the plug rod 3 extends into the connection between the truss rod 10 and the inner cavity of the installation groove 6, thereby separating and shaking the position of the truss rod 10 in the inner cavity of the installation groove 6. As the plug rod 3 is continuously inserted and shaken, it is convenient to quickly take out the truss rod 10 from the inner cavity of the installation groove 6. Threaded holes 11 are provided on the left and right sides of the rear side of the truss rod 10. Bolts 12 are detachably installed in the inner cavities of the threaded holes 11. The bolt 12 is divided into two parts: a screw rod and a nut. Threads matching the inner wall shape of the threaded hole 11 are provided on the outer surface of the screw rod. The cross-sectional shape of the nut is larger than the cross-sectional shape of the screw rod. The cross-sectional shape of the screw rod matches the shape of the inner cavity of the round hole 7. Therefore, during use, the screw rod part on one side of the bolt 12 passes through the round hole 7 and rotates into the inner cavity of the threaded hole 11, and cooperates with the nut to fix the combined truss rod 10 and the mounting block 5. A polygonal hole 13 is provided on the rear side of the bolt 12. The polygonal hole 13 does not penetrate the nut on one side of the bolt 12. The position where the round hole 7 is provided is mostly inside the combined device. Therefore, during use, a polygonal tool rod is used to extend it into the inner cavity of the polygonal hole 13,The bolt 12 is thereby rotated to fix the truss 10 and the mounting block 5.

[0025] Working principle: During operation, different numbers of mounting blocks 5 are welded to different surfaces of the base block 1 according to actual installation needs. For example, for the base block 1 at the bottom position, the mounting blocks 5 can be welded to the top outer surface, the left or right outer surface and the rear outer surface of the base block 1. If it is the base block 1 at the middle connection position, the mounting blocks 5 can be welded to the left and right outer surfaces, the top outer surface and the rear outer surface of the base block 1 respectively. Then, one end of the truss rod 10 with the threaded hole 11 on one side is installed into the inner cavity of the mounting groove 6, and the side of the truss rod 10 with the threaded hole 11 is aligned with the side of the mounting block 5 with the circular hole 7. Then, the screw rod part of the bolt 12 is inserted into the inner cavity of the threaded hole 11 through the circular hole 7, and the polygonal tool rod is inserted into the inner cavity of the polygonal hole 13 formed on the surface of the nut on one side of the bolt 12, so as to rotate the bolt 12 so that the bolt 12 is fully inserted into the inner cavity of the threaded hole 11 to fix the truss rod 10 and the mounting block 5.

[0026] When disassembly is required, first use the polygonal tool rod to insert it into the polygonal hole 13 on the rear side of the bolt 12, so as to rotate the bolt 12 to move it out of the inner cavity of the threaded hole 11, and then manually pass the hook ring 4 to take out the insertion rod 3, so that the pointed part of the insertion rod 3 is inserted along the inclined groove 9. As the insertion rod 3 is continuously extended, the truss rod 10 and the inner wall of the installation groove 6 are separated and shaken, so that the truss rod 10 can quickly detach from the inner cavity of the installation groove 6, which facilitates the separation of the truss rod 10 from the mounting block 5.

[0027] In summary, this easy-to-assemble building steel structure truss has the advantages of rapid assembly or disassembly and meeting the requirements of environments of different heights or widths, thereby improving overall practicality, compared with general similar devices.

[0028] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
