Description

Technical Field

[0001] The utility model belongs to the technical field of steel structure joints, and particularly relates to a waterproof structure for assembled steel structure joints. Background Technique

[0002] A steel structure is a structure composed of steel materials. Because of its light self-weight and simple construction, it is widely used in large factories, stadiums, super high-rise buildings, bridges and other fields. During the construction of a steel structure, a large number of joints will appear.

[0003] At present, assembled steel structure joints usually use multiple fixing bolts for fixation. When the fixing bolts connect and fix two steel plates, there is a lack of corresponding sealing and waterproof structures, which easily causes rainwater and the like to enter the bolt holes. After the fixing bolts are eroded by rainwater for a long time, they will rust, resulting in loosening of the connection joints of the two steel plates and affecting the stability of the steel structure connection joints.

[0004] In view of the above problems, we propose a waterproof structure for assembled steel structure joints. Content of the Utility Model

[0005] Technical Solution

[0006] In order to solve the above technical problems, the utility model provides a waterproof structure for assembled steel structure joints, including a first steel plate and a second steel plate. One end of the second steel plate is fixed with a mounting plate. A sealing rubber strip is arranged on the peripheral side of the outer wall of the mounting plate and is matched with the first steel plate. A plurality of threaded holes are opened on the first steel plate. Two rectangular grooves are opened on the mounting plate. A plurality of sealing grooves are opened on the inner wall of the rectangular grooves. Threaded grooves are opened at the bottoms of the sealing grooves and are in one-to-one correspondence with the threaded holes. Locking bolts are threadedly arranged between the threaded holes and the corresponding threaded grooves. A sealing ring is arranged on the outer side of the end head of the locking bolt and is matched with the sealing groove. A first rubber plate is movably arranged inside the rectangular groove. A second rubber plate is arranged on the outer side of the first rubber plate and is mutually matched with the outer side of the mounting plate. A connecting piece is arranged between the second rubber plate and the mounting plate.

[0007] The connecting piece includes a slot, a clamping groove, a plug rod and a rubber clamping block. A plurality of the slots are oppositely opened on the surface of the mounting plate close to the second steel plate. The clamping groove is opened at the bottom of the slot. A plurality of the plug rods are oppositely fixed on the side surface of the second rubber plate close to the mounting plate. The rubber clamping block is fixed at the end of the plug rod away from the second rubber plate.

[0008] The plug rod is mutually matched with the slot, and both the plug rod and the slot are in a funnel-shaped structure. The rubber clamping block is mutually matched with the slot and the clamping groove.

[0009] A plurality of mounting grooves are formed on a side of the first rubber plate away from the second rubber plate. A plurality of suction cups are arranged inside the mounting grooves, and the suction cups match with the inner wall of the rectangular groove.

[0010] A groove is formed on one side of the first rubber plate close to the second rubber plate, and the groove penetrates the second rubber plate. A fixing plate is arranged inside the groove, and a notch is formed on the fixing plate.

[0011] The sealing strip is a hollow structure, and the surfaces of the first steel plate, the second steel plate and the mounting plate are all coated with a polyurea coating layer.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] The utility model facilitates the fixing and connecting of the mounting plate and the first steel plate together through the threaded cooperation of the locking bolt, the threaded groove and the threaded hole, thereby realizing the purpose of assembling the second steel plate and the first steel plate together. Under the action of the sealing strip, the gap between the mounting plate and the first steel plate is effectively sealed to prevent rainwater from entering between the mounting plate and the first steel plate. At the same time, under the mutual cooperation of the sealing ring and the sealing groove, the threaded groove is effectively sealed. Combined with the mutual cooperation of the first rubber plate and the rectangular groove and the second rubber plate, the rectangular groove is further sealed to effectively prevent external rainwater from entering the threaded groove or the threaded hole, thereby preventing rainwater from eroding the locking bolt and affecting the use effect of the locking bolt, ensuring the stability of the connection between the first steel plate and the second steel plate, and solving the problem that the assembled steel structure node is usually fixed with multiple fixing bolts, and the fixing bolt lacks a corresponding sealing and waterproof structure when connecting and fixing the two steel plates, which easily causes rainwater to enter the bolt hole. After being eroded by rainwater for a long time, the fixing bolt will rust, causing the connection node of the two steel plates to become loose, thereby affecting the stability of the connection node of the steel structure.

Specific Embodiment

[0020] This specific embodiment is a waterproof structure for an assembled steel structure joint, as Figures 1-5 shown. The waterproof structure for the assembled steel structure joint includes the first steel plate 1 and the second steel plate 2. One end of the second steel plate 2 is fixed with a mounting plate 3. A sealing strip 4 is arranged on the outer periphery of the outer wall of the mounting plate 3 and is matched with the first steel plate 1. A plurality of threaded holes 5 are formed in the first steel plate 1. Two rectangular grooves 10 are formed in the mounting plate 3. A plurality of sealing grooves 9 are formed in the inner wall of the rectangular groove 10. A threaded groove 6 is formed at the bottom of the sealing groove 9 and corresponds to the threaded hole 5 one by one. A locking bolt 7 is threadedly arranged between the threaded hole 5 and the corresponding threaded groove 6. A sealing ring 8 is arranged on the outer side of the end head of the locking bolt 7 and is matched with the sealing groove 9. A first rubber plate 11 is movably arranged inside the rectangular groove 10. A second rubber plate 12 is arranged on the outer side surface of the first rubber plate 11 and is matched with the outer side surface of the mounting plate 3. A connecting member is arranged between the second rubber plate 12 and the mounting plate 3.

[0021] Through the threaded cooperation of the locking bolt 7 with the threaded groove 6 and the threaded hole 5, it is convenient to fixedly connect the mounting plate 3 and the first steel plate 1 together, thereby achieving the purpose of assembling the second steel plate 2 and the first steel plate 1. Among them, under the action of the sealing strip 4, the gap between the mounting plate 3 and the first steel plate 1 is effectively sealed, preventing rainwater from entering between the mounting plate 3 and the first steel plate 1. At the same time, under the mutual cooperation of the sealing ring 8 and the sealing groove 9, the threaded groove 6 is effectively sealed. Combining the mutual cooperation of the first rubber plate 11 and the rectangular groove 10 and the second rubber plate 12, the rectangular groove 10 is further sealed, effectively preventing external rainwater from entering the threaded groove 6 or the threaded hole 5, thereby avoiding rainwater from eroding the locking bolt 7 and affecting the use effect of the locking bolt 7, and ensuring the stability of the connection between the first steel plate 1 and the second steel plate 2.

[0022] The connecting piece includes a slot 13, a clamping groove 14, a plug rod 15 and a rubber clamping block 16. A number of slots 13 are oppositely formed on the side of the mounting plate 3 close to the second steel plate 2. The clamping groove 14 is formed at the bottom of the slot 13. A number of plug rods 15 are oppositely fixed on the side surface of the second rubber plate 12 close to the mounting plate 3. The rubber clamping block 16 is fixed at one end of the plug rod 15 away from the second rubber plate 12. The plug rod 15 and the slot 13 cooperate with each other, and both the plug rod 15 and the slot 13 are in a funnel-shaped structure. The rubber clamping block 16 cooperates with the slot 13 and the clamping groove 14. Through the cooperation between the plug rod 15 and the slot 13, combined with the cooperation between the rubber clamping block 16 and the slot 13 and the clamping groove 14, and with the deformable characteristic of the rubber clamping block 16, it is convenient to drive the rubber clamping block 16 to be clamped into the clamping groove 14 during the process of inserting the plug rod 15 into the slot 13, so as to achieve the purpose of limiting the second rubber plate 12, and ensure the stability and sealing effect between the second rubber plate 12 and the first rubber plate 11.

[0023] A number of mounting grooves 17 are formed on the side of the first rubber plate 11 away from the second rubber plate 12. A number of suction cups 18 are arranged inside the mounting grooves 17. The suction cups 18 cooperate with the inner wall of the rectangular groove 10 to further adsorb the first rubber plate 11 inside the rectangular groove 10, ensuring the stability of the first rubber plate 11.

[0024] A groove is formed on the side of the first rubber plate 11 close to the second rubber plate 12. The groove penetrates through the second rubber plate 12. A fixing plate 19 is arranged inside the groove. A notch 20 is formed on the fixing plate 19, which is convenient for removing the first rubber plate 11 from the inside of the rectangular groove 10 when disassembling the first steel plate 1 and the second steel plate 2 later.

[0025] The sealing strip 4 is of a hollow structure, which is convenient for tightly fitting the sealing strip 4 with the first steel plate 1 when connecting and fixing the mounting plate 3 and the first steel plate 1, ensuring the sealing effect between the sealing strip 4 and the mounting plate 3 and the first steel plate 1. The surfaces of the first steel plate 1, the second steel plate 2 and the mounting plate 3 are all coated with a polyurea coating layer, further improving the waterproof effect at the steel structure connection node.

[0028] Among them, under the action of the hollow structure of the sealing strip 4, after the mounting plate 3 and the first steel plate 1 are fixed together, the sealing strip 4 is driven to be tightly combined with the first steel plate 1, achieving the effect of sealing the gap between the mounting plate 3 and the first steel plate 1;

[0029] When the locking bolt 7 is screwed into the bottom of the threaded hole 5, the sealing ring 8 is driven to be stuck into the inside of the sealing groove 9, achieving the effect of sealing the outside of the threaded groove 6;

[0030] Then, the first rubber plate 11 is adjusted to be placed into the rectangular groove 10 through the notch 20, and the second rubber plate 12 is pressed to fit with the mounting plate 3. At the same time, under the action of the insertion rod 15, the rubber clamping block 16 is driven to pass through the insertion slot 13 and insert into the inside of the clamping slot 14;

[0031] At the same time, the suction cup 18 is driven to tightly adsorb on the inner wall of the rectangular groove 10, thereby achieving the purpose of limiting and fixing the first rubber plate 11 and the second rubber plate 12, making the first rubber plate 11 stable inside the rectangular groove 10 and making the second rubber plate 12 stable outside the rectangular groove 10, achieving the purpose of sealing the rectangular groove 10, effectively preventing rainwater from entering the threaded groove 6 or the threaded hole 5, eroding the locking bolt 7, causing the locking bolt 7 to rust, resulting in the loosening of the locking bolt 7 and affecting the stability of the steel structure connection node.
