Description

Technical Field

[0001] This invention relates to the field of steel structure technology, and more specifically, to a corrosion-resistant steel beam connection structure for industrial plants. Background Technology

[0002] Steel structure buildings are a new type of building system that uses steel plates and shaped steel to replace traditional reinforced concrete. They have advantages such as higher strength, better earthquake resistance, shorter construction period, reusability, and green environment, and are therefore widely used in industrial and civil buildings, such as steel structure industrial plants.

[0003] Multiple steel beams were connected on site by welding. However, the vibrations generated during operation inside the steel structure workshop could significantly affect the connection points between the steel beams and columns. Furthermore, due to the low stiffness of the lightweight steel beams, frequent vibrations occurred at the connections between the steel beams and columns, and between steel beams themselves. This could lead to loosening of the bolts at the connections and brittle fracture of the welds, posing a significant safety hazard.

[0004] Chinese patent application CN113789856A discloses a steel beam connection structure for a steel structure factory building. By setting an elastic steel plate at the top of the connection unit, the connection of the transverse steel beams has a certain shock absorption capacity when subjected to force, which avoids excessive stress at the connection and breakage during hoisting operations in the factory building, thus ensuring the overall safety of the steel structure factory building.

[0005] Although this type of steel beam connection structure for steel structure workshops avoids the problem of excessive stress and breakage at the connection point during hoisting operations inside the workshop, in the actual installation process, since the connection structure between steel beams and columns in prefabricated buildings is the key to the overall strength of the building, most common connection methods between steel beams and columns are fixed by several external bolts. The entire docking and installation process is very troublesome, and the connection strength is relatively low.

[0006] Therefore, a corrosion-resistant steel beam connection structure for industrial plants is proposed. Summary of the Invention

[0007] To address the problems existing in the prior art, the purpose of this invention is to provide a corrosion-resistant steel beam connection structure for industrial plants, which can increase the stability and ease of installation between columns, beams and slabs.

[0008] To solve the above problems, the present invention adopts the following technical solution.

[0009] A corrosion-resistant steel beam connection structure for industrial plants includes columns, plates, and beams. The plates are positioned on the upper side of the columns, and the beams are positioned on the outer side of the columns. A tapered fastener is fixedly installed on the lower end face of the plate corresponding to the column. The tapered fastener contains a first fixing mechanism and a transmission mechanism. The column contains a second fixing mechanism. The first fixing mechanism includes a support column fixedly installed on the upper end face of the tapered fastener. A transmission plate is slidably connected to the outer surface of the support column. A spring is fixedly installed between the upper end face of the transmission plate and the plate, and the spring is sleeved on the outer surface of the support column. The first fixing mechanism operates by inserting the column into the tapered fastener, strengthening the stability between the column and the plate. The transmission mechanism further strengthens the fixing strength between the plate and the column while transmitting power to the second fixing mechanism, allowing the beams and columns to engage and be fixed for easy installation.

[0010] Furthermore, the fixing mechanism also includes a slot opened inside the tapered fixing member, a fixing shaft fixedly installed inside the slot, a transmission rod provided inside the slot, the transmission rod being rotatably connected to the fixing shaft, and one end of the transmission rod being rotatably connected to the transmission plate.

[0011] Furthermore, a sliding sleeve is fixedly installed on the outer surface of the tapered fixing member, and an insert rod is slidably connected inside the sliding sleeve. A connecting rod is fixedly installed at the upper end of the insert rod, and the other end of the transmission rod is rotatably connected to the upper end of the connecting rod.

[0012] Furthermore, a fixing plate is fixedly installed on the upper side of the outer surface of the column, and a slot is opened on the upper end of the fixing plate corresponding to the insertion rod. A connector is provided on the lower side of the fixing plate, and the connector is fixedly connected to the column. A fixing bolt is screw-driven between the connector and the insertion rod.

[0013] Furthermore, the slot, transmission rod, fixed shaft, connecting rod, sliding sleeve, insert rod, connector, slot and fixing bolt are all provided in multiple sets and are arranged in a ring. One end of each set of transmission rods is rotatably connected to the transmission plate.

[0014] Furthermore, the transmission mechanism includes a threaded groove one on the upper end face of the column and a threaded groove two on the upper end face of the plate. A threaded rod is helically connected between the threaded groove one and the threaded groove two, and the threaded rod has threads only on the upper half of its outer surface.

[0015] Furthermore, the second fixing mechanism includes an inner cavity opened on the lower side of the column, the inner cavity being interconnected with the first threaded groove, a rotating shaft being rotatably connected to the lower end of the inner cavity, a turntable being fixedly installed on the upper end of the rotating shaft, a slot being opened on the upper surface of the turntable, and a locking block being fixedly installed on the lower end of the threaded rod corresponding to the slot.

[0016] Furthermore, the second fixing mechanism also includes a slide rail fixedly installed on the outer surface of the column. The slide rail is in communication with the inner cavity, and the crossbeam is slidably connected inside the slide rail and extends into the inner cavity through the slide rail.

[0017] Furthermore, a second clamp is fixedly installed at one end of the crossbeam, and a first clamp is fixedly installed on the outer surface of the turntable corresponding to the second clamp. Both the first clamp and the second clamp are L-shaped.

[0018] Furthermore, the crossbeam, slide rail, and clamps one and two are each provided in three sets, arranged in a circular pattern.

[0019] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0020] (1) This scheme sets up a fixing mechanism one, which uses the column to squeeze the transmission plate when it is inserted into the conical fixing piece, so that the transmission plate carries multiple sets of transmission rods to rise and deflect, thereby inserting the rod into the slot and fixing it with fixing bolts, which speeds up the installation efficiency between the column and the plate, and at the same time improves the connection strength between the column and the plate.

[0021] (2) This scheme further enhances the connection strength between the plate and the column by setting up a transmission mechanism and using a manually twisted threaded rod to make the threaded rod connected by a helical transmission between threaded groove one and threaded groove two, and at the same time, it will also transmit the fixed mechanism two.

[0022] (3) This solution sets up a second fixing mechanism and uses a transmission mechanism to drive the turntable to rotate, thereby engaging and fixing the first clamp and the second clamp, so that the beam and the column are engaged and fixed, achieving the purpose of convenient installation.

[0033] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0034] Please see Figures 1 to 8A corrosion-resistant steel beam connection structure for industrial plants includes columns 1, plates 2, and beams 3. Plate 2 is positioned above the columns 1, and beams 3 are positioned outside the columns 1. A conical fastener 4 is fixedly installed on the lower end of plate 2 corresponding to column 1. The conical fastener 4 contains a first fixing mechanism and a transmission mechanism. A second fixing mechanism is installed inside the columns 1. The first fixing mechanism includes a support column 28 fixedly installed on the upper end of the conical fastener 4. A transmission plate 6 is slidably connected to the outer surface of the support column 28. A spring 7 is fixedly installed between the upper end of the transmission plate 6 and plate 2, and the spring 7 is sleeved on the outer surface of the support column 28. The first fixing mechanism operates by inserting column 1 into the conical fastener 4, strengthening the stability between column 1 and plate 2. The transmission mechanism further strengthens the fixing strength between plate 2 and column 1 while simultaneously transmitting power to the second fixing mechanism, allowing beams 3 to engage and fix with column 1 for easy installation. The first fixing mechanism also includes an opening inside the conical fastener 4. Some slots, slot 5 has a fixed shaft 8 fixedly installed inside, and a transmission rod 9 is set inside slot 5. The transmission rod 9 is rotatably connected to the fixed shaft 8. One end of the transmission rod 9 is rotatably connected to the transmission plate 6. A sliding sleeve 11 is fixedly installed on the outer surface of the tapered fixing part 4. An insert rod 12 is slidably connected inside the sliding sleeve 11. A connecting rod 10 is fixedly installed on the upper end of the insert rod 12. The other end of the transmission rod 9 is rotatably connected to the upper end of the connecting rod 10. A fixing plate 13 is fixedly installed on the upper side of the outer surface of the column 1. The upper end of the fixed plate 13 is provided with a slot 15 corresponding to the insertion rod 12. A connector 14 is provided on the lower side of the fixed plate 13. The connector 14 is fixedly connected to the column 1. The connector 14 and the insertion rod 12 are connected by a screw drive with a fixing bolt 16. The slot 5, transmission rod 9, fixed shaft 8, connecting rod 10, sliding sleeve 11, insertion rod 12, connector 14, slot 15 and fixing screw 16 are all provided in multiple sets and are arranged in a ring. One end of each set of transmission rods 9 is rotatably connected to the transmission plate 6.

[0035] By adopting the above technical solution, the current common connection method between steel beams and steel columns 1 is mostly fixed by a number of external bolts. The entire docking and installation process is very troublesome and the connection strength is low. Therefore, this solution sets up a fixing mechanism. When column 1 is inserted into the conical fixing piece 4, it squeezes the transmission plate 6, causing the transmission plate 6 to carry multiple sets of transmission rods 9 to rise and deflect, thereby inserting the insertion rod 12 into the slot 15 and fixing it with fixing bolts 16. This speeds up the installation efficiency between column 1 and plate 2 and improves the connection strength between column 1 and plate 2. Specifically: First, the fixing installation between column 1 and plate 2 is carried out. Column 1... The upper end of the rod is inserted into the conical fixing part 4. During the insertion of the column 1, the transmission plate 6 is squeezed and slides upward. One end of the transmission rod 9 is rotatably connected to the transmission plate 6. Therefore, the transmission plate 6 will carry one end of the transmission rod 9 upward, so that the transmission rod 9 will deflect around the fixed shaft 8. The other end of the transmission rod 9 will descend. The other end of the transmission rod 9 is rotatably connected to the connecting rod 10. Therefore, the connecting rod 10 will drive the insertion rod 12 to slide down inside the sliding sleeve 11 and insert it into the slot 15 opened on the fixed plate 13. Then the end head is in the connector 14. At this time, the insertion rod 12 and the connector 14 can be fixedly installed by fixing the bolt 16.

[0036] like Figure 8 As shown, the transmission mechanism includes a threaded groove 17 on the upper end face of the column 1 and a threaded groove 18 on the upper end face of the plate 2. A threaded rod 19 is screwed between the threaded groove 17 and the threaded groove 18, and the threaded rod 19 has threads only on the upper half of its outer surface.

[0037] By adopting the above technical solution, this solution further enhances the connection strength between plate 2 and column 1 by setting up a transmission mechanism and using manual twisting of threaded rod 19 to make threaded rod 19 be connected by screw transmission between threaded groove 17 and threaded groove 18 respectively. At the same time, it will also transmit the second fixing mechanism. Specifically: then the crossbeam 3 is inserted into the inner cavity 20 through slide rail 25, then the threaded rod 19 is inserted into threaded groove 17 and threaded groove 18 and twisted, so that the threaded rod 19 is screw-fixed to plate 2 through threaded groove 17 and screw-fixed to column 1 through threaded groove 18.

[0038] like Figure 4As shown, the second fixing mechanism includes an inner cavity 20 opened on the lower side of the column 1. The inner cavity 20 is connected to the threaded groove 17. The lower end of the inner cavity 20 is rotatably connected to a rotating shaft 21. A turntable 22 is fixedly installed on the upper end of the rotating shaft 21. A slot 23 is opened on the upper end surface of the turntable 22. A locking block 24 is fixedly installed on the lower end of the threaded rod 19 corresponding to the slot 23. The second fixing mechanism also includes a slide rail 25 fixedly installed on the outer surface of the column 1. The slide rail 25 is connected to the inner cavity 20. The crossbeam 3 is slidably connected to the inside of the slide rail 25 and extends to the inside of the inner cavity 20 through the slide rail 25. A locking piece 27 is fixedly installed on one end of the crossbeam 3. A locking piece 26 is fixedly installed on the outer surface of the turntable 22 corresponding to the locking piece 27. Both the locking piece 26 and the locking piece 27 are L-shaped. There are three sets of the crossbeam 3, the slide rail 25, the locking piece 26 and the locking piece 27, which are arranged in a ring.

[0039] By adopting the above technical solution, this solution sets up a second fixing mechanism and uses a transmission mechanism to drive the turntable 22 to rotate, thereby engaging and fixing the first clamp 26 and the second clamp 27, so that the crossbeam 3 and the column 1 are engaged and fixed, achieving the purpose of convenient installation. Specifically, when the threaded rod 19 is inserted, the clamp 24 is simultaneously inserted into the clamp slot 23, and as the threaded rod 19 rotates, the turntable 22 rotates synchronously. The rotation of the turntable 22 will carry the first clamp 26 to rotate, so that the first clamp 26 and the second clamp 27 engage and fix each other, thus completing the fixed connection of the crossbeam 3.

[0040] Instructions for use: First, fix the column 1 and plate 2 together. Insert the upper end of the column 1 into the conical fixing part 4. During the insertion of the column 1, it will squeeze the transmission plate 6, causing the transmission plate 6 to slide upward. One end of the transmission rod 9 is rotatably connected to the transmission plate 6, so the transmission plate 6 will carry one end of the transmission rod 9 upward, causing the transmission rod 9 to deflect around the fixed shaft 8. The other end of the transmission rod 9 will then descend. The other end of the transmission rod 9 is rotatably connected to the connecting rod 10, which will drive the insertion rod 12 to slide down inside the sliding sleeve 11 and insert it into the slot 15 opened on the fixed plate 13. Then, the end head is in the connecting part 14, at which point it can be fixed with bolts. 16. Insert rod 12 and connector 14 are fixedly installed. Then, crossbeam 3 is inserted into inner cavity 20 through slide rail 25. Next, threaded rod 19 is inserted into thread groove 17 and thread groove 28 and twisted so that threaded rod 19 is screwed to plate 2 through thread groove 17 and screwed to column 1 through thread groove 28. When threaded rod 19 is inserted, locking block 24 is inserted into locking slot 23 at the same time. As threaded rod 19 rotates, turntable 22 rotates synchronously. The rotation of turntable 22 will carry locking piece 26 to rotate, so that locking piece 26 and locking piece 27 engage and fix each other. In this way, the fixed connection of crossbeam 3 is completed.

[0041] The above description is merely a preferred embodiment of the present invention; however, the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and its improved concepts, should be covered within the scope of protection of the present invention.
