Description

Technical Field

[0001] The present invention relates to the technical field of steel structure crossbeams, and particularly to a spliced steel structure crossbeam. Background Art

[0002] Steel structures, as the name implies, are structures composed of steel materials. It is one of the main building structure types, mainly composed of steel beams, steel columns, steel trusses and other components made of sections and steel plates, and processed by rust removal and rust prevention processes such as silanization, pure manganese phosphating, water washing and drying, galvanizing, etc. The components or parts of steel structures are usually connected by welds, bolts or rivets, and are widely used in large factories, stadiums, super high-rise buildings and other fields. The crossbeam is an important part that spans across the column walls in building construction to support other materials. The steel structure crossbeam is a crossbeam made of steel structure. Compared with the traditional crossbeams made of wood, steel, cement, etc., the steel structure crossbeam has the characteristics of lighter structure and simpler construction;

[0003] For example, an assembled steel structure crossbeam with the Chinese patent authorization publication number CN112095917B includes an installation base plate, a support rod, a splicing kit and a strip crossbeam. The support rod is installed on the installation base plate by means of bolt connection, the splicing kit is installed on the support rod, and the strip crossbeam is installed inside the splicing kit. The present invention can solve the following problems that often occur when the existing assembled crossbeams are in use: a: When the existing assembled crossbeams are temporarily assembled, in order to meet the use requirements, it is often necessary to adjust the height of the crossbeam, so it is necessary to manually reassemble the crossbeam again, which greatly wastes time and affects work efficiency; b: When the existing assembled crossbeams are temporarily assembled, the crossbeam often shakes unstably, posing a great safety hazard and easily causing safety accidents;

[0004] Another example is a steel structure crossbeam with the Chinese patent authorization publication number CN110318467B, which includes a left crossbeam and a right crossbeam. Both the left crossbeam and the right crossbeam are of S-shaped structure. The left crossbeam and the right crossbeam are docked through a connection mechanism. Hanging mechanisms are provided at the bottom ends of the left crossbeam and the right crossbeam. The connection mechanism includes a left connection block. The right end of the left connection block is connected to a right connection block through a splicing mechanism. The left connection block and the right connection block are evenly arranged at the top and bottom of the docking position of the left crossbeam and the right crossbeam. A connecting plate is rotatably provided on the leftmost left connection block and the rightmost left connection block. The connecting plate is bolted to one end of the docking of the left crossbeam or the right crossbeam. A steel structure crossbeam provided by the present invention is convenient for flexible disassembly and assembly, and is convenient for installation and use; some auxiliary audio or lighting equipment can be hung, and the adaptability is good.

[0005] However, most of the steel structure crossbeams on the current market still have some deficiencies. For example, most of the existing steel structure crossbeams need to adjust the installation height of the crossbeam support structure according to the on-site installation height, which is not convenient to quickly adapt to different installation heights. Moreover, most of them need to fix the crossbeam by welding or riveting, which is not convenient for automatic installation. At the same time, it is mostly difficult to disassemble the crossbeam after installation, and thus there are certain usage defects. Therefore, we propose a spliced steel structure crossbeam to solve the problems mentioned above. Summary of the Invention

[0006] The purpose of the present invention is to provide a spliced steel structure crossbeam to solve the problems in the above-mentioned background technology, that is, most of the current steel structure crossbeams need to adjust the installation height of the crossbeam support structure according to the on-site installation height, which is not convenient to quickly adapt to different installation heights, and most of them need to fix the crossbeam by welding or riveting, which is not convenient for automatic installation. At the same time, it is mostly difficult to disassemble the crossbeam after installation.

[0007] To achieve the above purpose, the present invention provides the following technical solution: A spliced steel structure crossbeam, comprising:

[0008] Columns, a fixing block is fixedly installed on the outer end face of the column, and an installation groove is opened on the end face of the fixing block close to the vertical center line of the column. A first support assembly is arranged inside the fixing block, and a second support assembly is arranged on the right side of the first support assembly. The first support assembly is composed of a first support block, a first connection groove and a first connection block. The second support assembly is composed of a second support block, a second connection groove and a second connection block;

[0009] A limiting groove is opened inside the first support assembly. A connection assembly is connected inside the limiting groove, and the connection assembly includes a first mounting plate, a second mounting plate and a spring. A pressing block is arranged above the first support assembly and the second support assembly. The upper end of the pressing block is fixedly connected by welding to a first steel structure crossbeam, and a second steel structure crossbeam is fixedly connected to the outside of the first steel structure crossbeam;

[0010] A first stop block is fixedly installed at the lower end of the first support assembly. A first push block, which is also fixedly connected to the lower end of the first support assembly, is arranged on the right side of the first stop block. A second stop block is fixedly connected to the lower end of the second support assembly, and a second push block, which is also fixedly connected to the lower end of the second support assembly, is arranged on the left side of the second stop block.

[0011] With the above technical solution, the first support component and the second support component support the pressing block. Since the pressing block moves downward during the process of being pressed by the gravity of the first steel structure cross beam and the second steel structure cross beam, the downward movement of the pressing block causes the separation between the first support component and the second support component. By increasing the distance between the first support block and the second support block, the first connection block and the second connection block are inserted into the interior of the installation groove, and then the first support component and the second support component are fixedly supported by the fixing block.

[0012] As a preferred technical solution of the present invention, the column and the fixing block are both symmetrically arranged before and after with respect to the vertical center line of the second steel structure cross beam, and the fixing block is symmetrically arranged left and right with respect to the vertical center line of the column;

[0013] With the above technical solution, the column and the fixing block support the first support component and the second support component.

[0014] As a preferred technical solution of the present invention, the installation grooves are equally spaced from top to bottom on the end face of the fixing block close to the vertical center line of the column;

[0015] With the above technical solution, connecting the first support component and the second support component to the installation grooves at different positions can change the installation height of the first steel structure cross beam and the second steel structure cross beam.

[0016] As a preferred technical solution of the present invention, both the first support block and the second support block are arranged inside the fixing block, and a first connection groove is formed at the right end of the first support block, and the left end face of the first connection groove is inclined;

[0017] With the above technical solution, the first support component supports the first steel structure cross beam and the second steel structure cross beam.

[0018] As a preferred technical solution of the present invention, a first connection block is fixedly connected to the left end face of the first support block, and the first connection blocks are equally spaced from top to bottom on the left end face of the first support block;

[0019] With the above technical solution, by connecting the first connection block to the installation groove, a limiting effect is exerted on the first support block.

[0020] As a preferred technical solution of the present invention, a second connection groove is formed at the left end of the second support block, and the right end face of the second connection groove is inclined;

[0021] With the above technical solution, the second support component supports the first steel structure cross beam and the second steel structure cross beam.

[0022] As a preferred technical solution of the present invention, a second connection block is fixedly connected to the right end face of the second support block, and the second connection blocks are arranged at equal intervals from top to bottom on the right end face of the second support block, and both the second connection block and the first connection block are engaged with the fixed block through the installation groove;

[0023] With the above technical solution, by connecting the second connection block with the installation groove, a limiting effect is exerted on the second support block.

[0024] As a preferred technical solution of the present invention, both the first mounting plate and the second mounting plate are fixedly connected to the left end face of the second support block, and both the first mounting plate and the second mounting plate are slidably connected to the first support block through the limiting groove;

[0025] With the above technical solution, the first support component and the second support component are limitedly connected by the first mounting plate and the second mounting plate, and at the same time, lateral movement can occur between the first support component and the second support component.

[0026] As a preferred technical solution of the present invention, springs are evenly distributed inside the first mounting plate and the second mounting plate, and the springs are fixedly connected between the first support block and the second support block;

[0027] With the above technical solution, due to the elastic force of the springs, the first support block and the second support block remain in contact without external force.

[0028] As a preferred technical solution of the present invention, the vertical cross-section of the pressing block is trapezoidal, and the pressing block is slidably connected to the first support block and the second support block through the first connection groove and the second connection groove respectively, and the pressing block is symmetrically arranged about the vertical center line of the first steel structure cross beam;

[0029] With the above technical solution, the first support component and the second support component support the pressing block. At the same time, during the downward pressing process of the pressing block, the first support component and the second support component are separated by the acting force of the pressing block, and the pressing block supports the first steel structure cross beam.

[0030] Compared with the prior art, the beneficial effects of the present invention are as follows: This spliced steel structure cross beam is convenient for automatic installation, and is convenient and fast to adapt to different installation heights. At the same time, it solves the problem that most of the current steel structure cross beams need to be fixed by welding or riveting, and are mostly difficult to disassemble after installation;

[0031] 1. There is a pressing block, a connecting component and a first supporting component. By placing the pressing block inside the first supporting block and the second supporting block, due to the gravity of the first steel structure crossbeam and the second steel structure crossbeam acting on the pressing block, the pressing block naturally presses down, generating a lateral pressure on the first connecting groove and the second connecting groove, thereby increasing the distance between the first supporting block and the second supporting block. By inserting the first connecting block and the second connecting block into the inside of the installation groove, the first supporting component and the second supporting component are connected to the fixing block in a limited way. Then, the first supporting component and the second supporting component play a supporting role on the pressing block, thus installing the first steel structure crossbeam and the second steel structure crossbeam, which is convenient for automatic installation;

[0032] 2. There is a first supporting component, a fixing block and an installation groove. The installation grooves are equally spaced from top to bottom on the end face of the fixing block close to the vertical center line of the column. Since both the second connecting block and the first connecting block are engaged with the fixing block through the installation grooves, connecting the first supporting component and the second supporting component to the installation grooves at different positions can change the installation height of the first steel structure crossbeam and the second steel structure crossbeam, and it is convenient to quickly adapt to different installation heights;

[0033] 3. There is a pressing block, an installation groove and a second supporting component. By pressing the first pushing block or the second pushing block against one side of the vertical center line of the pressing block, the first supporting block approaches the second supporting block, and at the same time the spring is compressed and shortened, so that the first connecting block or the second connecting block can be separated from the installation groove, and then the first supporting component and the second supporting component can be disassembled, solving the problem that most of the currently installed steel structure crossbeams are difficult to disassemble.

Detailed implementation mode

[0041] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. 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 shall fall within the protection scope of the present invention.

[0042] Please refer to Figure 1-6 , the present invention provides a technical solution: a spliced steel structure cross beam, including a column 1, a fixed block 2, an installation groove 3, a first support assembly 4, a second support assembly 5, a limit groove 6, a connection assembly 7, a pressing block 8, a first steel structure cross beam 9, a second steel structure cross beam 10, a first stop block 11, a second stop block 12, a first push block 13 and a second push block 14;

[0043] The outer end surface of the column 1 is fixedly installed with a fixed block 2, and an installation groove 3 is opened on the end surface of the fixed block 2 close to the vertical center line of the column 1. A first support assembly 4 is arranged inside the fixed block 2, and a second support assembly 5 is arranged on the right side of the first support assembly 4. As Figure 1 and Figure 5 shown, the column 1 and the fixed block 2 are both symmetrically arranged before and after the vertical center line of the second steel structure cross beam 10, and the fixed block 2 is symmetrically arranged left and right about the vertical center line of the column 1. At the same time, the installation grooves 3 are equally spaced from top to bottom on the end surface of the fixed block 2 close to the vertical center line of the column 1. The column 1 and the fixed block 2 play a supporting role for the first support assembly 4 and the second support assembly 5, and the fixed block 2 plays a role of limiting connection for the first support assembly 4 and the second support assembly 5 through the installation groove 3;

[0044] Specifically, as Figure 1 , Figure 2 and Figure 6As shown in the figure, the first support assembly 4 is composed of a first support block 401, a first connection groove 402 and a first connection block 403. The second support assembly 5 is composed of a second support block 501, a second connection groove 502 and a second connection block 503. Both the first support block 401 and the second support block 501 are arranged inside the fixed block 2. A first connection groove 402 is opened at the right end of the first support block 401, and a first connection block 403 is fixedly connected to the left end face of the first support block 401. At the same time, a second connection groove 502 is opened at the left end of the second support block 501, and a second connection block 503 is fixedly connected to the right end face of the second support block 501. A pressing block 8 is arranged above the first support assembly 4 and the second support assembly 5, and a first steel structure cross beam 9 is fixedly connected by welding to the upper end of the pressing block 8. And a second steel structure cross beam 10 is fixedly connected to the outside of the first steel structure cross beam 9, as Figure 1 shown in the figure, the pressing block 8 is symmetrically arranged before and after the vertical center line of the first steel structure cross beam 9. The first support assembly 4 and the second support assembly 5 play a supporting role for the pressing block 8;

[0045] Specifically, as Figure 1 、 Figure 3 and Figure 6 shown in the figure, a limiting groove 6 is opened inside the first support assembly 4, and an engaging assembly 7 is connected to the inside of the limiting groove 6. And the engaging assembly 7 includes a first mounting plate 701, a second mounting plate 702 and a spring 703. Combining Figure 3 and Figure 6 shown in the figure, both the first mounting plate 701 and the second mounting plate 702 are fixedly connected to the left end face of the second support block 501, and both the first mounting plate 701 and the second mounting plate 702 are slidably connected to the first support block 401 through the limiting groove 6. Springs 703 are evenly distributed inside the first mounting plate 701 and the second mounting plate 702, and the springs 703 are fixedly connected between the first support block 401 and the second support block 501. The first mounting plate 701 and the second mounting plate 702 play a role in limiting the connection between the first support assembly 4 and the second support assembly 5, and lateral movement can occur between the first support assembly 4 and the second support assembly 5. At the same time, through the elastic force of the spring 703, the right end face of the first support block 401 and the left end face of the second support block 501 can be kept in contact without external force;

[0046] Specifically, as Figure 4 and Figure 5As shown in the figure, a first stop block 11 is fixedly installed at the lower end of the first support assembly 4, and a first push block 13, which is also fixedly connected to the lower end of the first support assembly 4, is arranged on the right side of the first stop block 11. A second stop block 12 is fixedly connected to the lower end of the second support assembly 5, and a second push block 14, which is also fixedly connected to the lower end of the second support assembly 5, is arranged on the left side of the second stop block 12. The first stop block 11 and the second stop block 12 respectively play a limiting role on the first support block 401 and the second support block 501. When the first support block 401 and the second support block 501 are subjected to the downward pressure of the pressing block 8, they are prone to tilt towards the vertical center line side of the pressing block 8. The left end face of the first stop block 11 and the right end face of the second stop block 12 abut against the installation groove 3, playing a further supporting and limiting role on the first support block 401 and the second support block 501.

[0047] When using this spliced steel structure crossbeam, first move the first support assembly 4 and the second support assembly 5 to the appropriate installation height position. Specifically, as Figure 2 、 Figure 3 and Figure 4 shown, since the left end face of the first connection groove 402 and the right end face of the second connection groove 502 are both inclined, and the first connecting block 403 and the second connecting block 503 are respectively arranged at equal intervals from top to bottom on the left end face of the first support block 401 and the right end face of the second support block 501. At the same time, the vertical cross-section of the pressing block 8 is trapezoidal, and the pressing block 8 is slidably connected to the first support block 401 and the second support block 501 through the first connection groove 402 and the second connection groove 502 respectively. Place the pressing block 8 inside the first connection groove 402 and the second connection groove 502. Due to the gravity of the first steel structure crossbeam 9 and the second steel structure crossbeam 10 acting on the pressing block 8, the pressing block 8 naturally presses downwards, generating a lateral pressure on the first connection groove 402 and the second connection groove 502, thereby increasing the distance between the first support block 401 and the second support block 501;

[0048] Specifically, as Figure 2 、 Figure 4 and Figure 5As shown in the figure, the spring 703 elongates under the tensile force. At the same time, the first connecting block 403 and the second connecting block 503 are inserted into the interior of the installation groove 3. As a result, both the second connecting block 503 and the first connecting block 403 are engaged with the fixed block 2 through the installation groove 3. The first support assembly 4 and the second support assembly 5 are fixedly supported by the fixed block 2. Then, the pressing block 8 is supported by the first support assembly 4 and the second support assembly 5, thereby fixedly installing the first steel structure crossbeam 9 and the second steel structure crossbeam 10. When it is necessary to disassemble the spliced steel structure crossbeam, by pinching the first push block 13 and the second push block 14 inward, the first support block 401 approaches the second support block 501. At the same time, the spring 703 is compressed and shortened, so that the first connecting block 403 or the second connecting block 503 can be separated from the installation groove 3, and then the first support assembly 4 and the second support assembly 5 can be disassembled. This is the usage method of the spliced steel structure crossbeam.

[0049] The standard parts used in the present invention can all be purchased from the market. The special-shaped parts can be customized according to the description in the specification and the drawings. The specific connection methods of each part all adopt conventional means such as bolts, rivets, and welding that are mature in the prior art.
