Description

Technical Field

[0001] This utility model relates to the field of H-beam connection technology, specifically a modular self-locking connection structure for the assembly of H-beams. Background Technology

[0002] H-beams are steel structural beams with an "H"-shaped cross-section, made of welded or rolled web and upper and lower flanges. They are rationally designed, possess high bending and torsional stiffness, strong load-bearing capacity, and are lightweight, effectively saving steel consumption. H-beams come in various specifications, with different heights, widths, and thicknesses customizable to meet project requirements, offering strong adaptability. They are widely used in structural engineering projects such as buildings, bridges, and industrial plants, serving as key components such as load-bearing beams and support beams, significantly improving structural stability and safety. Furthermore, H-beams are easy to construct, shortening construction time and reducing overall costs, making them an indispensable high-quality building material in modern engineering.

[0003] H-beams can be connected using connectors. Traditionally, multiple bolts are used to connect the connectors to the H-beams on both sides. In practice, at least two or more bolts need to be locked in place, which can be inconvenient initially. Therefore, we propose a modular self-locking connection structure for the assembly of H-beams. Summary of the Invention

[0004] The purpose of this utility model is to provide a modular self-locking connection structure for the assembly of H-beams. By setting a plastic cylinder and placing a plug on the surface of the connector, the H-beam can automatically fall into the locking hole of the H-beam after insertion, thereby realizing a temporary self-locking structure for the connector and the H-beam. This facilitates the subsequent use of bolts with higher connection strength to achieve a firm connection of the H-beam, and solves the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a modular self-locking connection structure for the assembly of H-beams, comprising a connector and an H-beam. The connector is H-shaped, and vertical first and second plastic cylinders are symmetrically arranged on both sides of the connector's surface. A first and second plug are respectively placed inside the first and second plastic cylinders, and the bottoms of the first and second plugs are placed in through holes opened on the upper surface of the connector. Plastic liners are inserted into the interior of both sides of the connector, and the bottoms of the first and second plugs are supported on the surface of the plastic liners. A first locking hole and a second locking hole are opened on both sides of the end of the H-beam. The diameter of the second locking hole is smaller than the diameter of the first plug but larger than the diameter of the second plug, and the diameter of the first locking hole is larger than the diameter of the first plug. When the H-beam is pushed into the interior of both sides of the connector, it will push out the plastic liners and align the first and second plugs with the first and second locking holes, and fall down through the first and second locking holes of the H-beam respectively. The connector and the H-beam are locked together by bolts.

[0006] By adopting the above technical solution, after the H-beam is inserted into the inside of the connector from the side, the plastic liner is pushed open, allowing the first and second bolts to fall and insert into the first and second locking holes to achieve self-locking. This makes it easier to use bolts to more firmly connect and lock the connector and the H-beam.

[0007] Optionally, a locking structure is provided between the plastic liner and the connector.

[0008] By adopting the above technical solution, the plastic liner can be prevented from falling off before the H-beam is pushed in.

[0009] Optionally, the locking structure includes aligned limiting holes on the surfaces of the plastic liner and the vertical portion of the connector, and a limiting bolt passing through the limiting holes through the plastic liner and the connector.

[0010] Optionally, a rubber ring is fitted around the outer end of the limiting bolt, and the rubber ring is attached to the inner surface of the plastic liner on the other side.

[0011] By adopting the above technical solution, the rubber ring is placed around the outer ring of the limit bolt, which can prevent the limit bolt from slipping off.

[0012] Optionally, the surface of the connector is provided with mounting holes evenly distributed, and the ends of the H-beam are provided with connecting holes distributed in the same manner as the mounting holes.

[0013] By adopting the above technical solution, the bolt passes through the connector and the H-beam through the mounting hole and the connection hole.

[0014] Optionally, the surface of the connector below the first and second plastic cylinders is provided with a threaded groove, and the first and second plastic cylinders can be detachably connected to the surface of the connector by screwing them into the threaded groove.

[0015] By adopting the above technical solution, after the first and second plugs are put down, the first and second plastic cylinders can be twisted off and removed respectively, avoiding the occupation of a large space.

[0016] Compared with the prior art, the beneficial effects of the technical solution of this application are as follows: 1. The technical solution of this application provides a plastic cylinder with a plug on the surface of the connector, which allows the H-beam to automatically fall into the locking hole of the H-beam after insertion, thereby achieving a temporary self-locking structure for the connector and the H-beam. This facilitates the subsequent use of bolts with higher connection strength to achieve a firm connection of the H-beam.

[0017] 2. The technical solution of this application, by setting the diameter of the first plug and the first locking hole to be larger, while the diameter of the second plug and the second locking hole is slightly smaller, can avoid the first plug being inserted into the second locking hole first when the H-beam is pushed in from the side, thus preventing the H-beam from being pushed in further.

[0020] Please see Figure 1-5 This utility model provides a technical solution: a modular self-locking connection structure for the assembly of H-beams, including a connector 1 and an H-beam 6. The connector 1 is H-shaped, and mounting holes 11 are evenly distributed on the surface of the connector 1. The ends of the H-beam 6 are evenly distributed with connecting holes 63 in the same manner as the mounting holes 11. When the H-beam 6 is inserted into the connector 1, the mounting holes 11 will align with the connecting holes 63. At this time, bolts 7 can be used to pass through the mounting holes 11 and the connecting holes 63 to the H-beam and the connector 1 to achieve the purpose of locking the two.

[0021] In actual operation, the H-beam 6 is inserted into the inside of the connector 1. After the bolt 7 is tightened and locked, it is necessary to maintain the alignment and support of the H-beam 6 and the connector 1, which is not conducive to the installation operation.

[0022] To solve this problem, vertical first plastic cylinder 3 and second plastic cylinder 31 are symmetrically arranged on both sides of the surface of connector 1. First plug 32 and second plug 33 are respectively placed inside the first plastic cylinder 3 and the second plastic cylinder 31. Through holes 21 are provided on the surface of connector 1 at the bottom of the first plastic cylinder 3 and the second plastic cylinder 31, and the bottom of the first plug 32 and the second plug 33 are placed in the through holes 21 opened on the upper surface of connector 1.

[0023] The H-beam 6 has a first locking hole 61 and a second locking hole 62 on both sides of its end. When the H-beam 6 is inserted into the inside of the connector 1, the first bolt 32 will be aligned with the first locking hole 61 and the second bolt 33 will be aligned with the second locking hole 62. Furthermore, plastic liners 4 are inserted into the inside of both sides of the connector 1, and the bottoms of the first bolt 32 and the second bolt 33 are supported on the surface of the plastic liners 4. When the H-beam 6 is not inserted into the inside of the connector 1, the bottoms of the first bolt 32 and the second bolt 33 are limited by the plastic liners 4 to prevent them from falling off. When the H-beam 6 is inserted into the inside of the connector 1 and pushes out the plastic liners 4, the bottoms of the first bolt 32 and the second bolt 33 are no longer limited, causing the first bolt 32 and the second bolt 33 to fall off and insert into the first locking hole 61 and the second locking hole 62 respectively, thus penetrating the H-beam 6 and achieving temporary self-locking of the H-beam 6, which facilitates the tightening of the bolt 7.

[0024] In addition, aligned limiting holes 51 are opened on the vertical surfaces of the plastic liner 4 and the connector 1. A limiting bolt 5 is also provided, which passes through the limiting hole 51 and penetrates the plastic liner 4 and the connector 1 as a locking structure to lock the plastic liner 4, preventing the plastic liner 4 from slipping off during transportation and causing the first plug 32 and the second plug 33 to fall off. The outer ring of the end of the limiting bolt 5 is fitted with a rubber ring 52, which is attached to the inner surface of the plastic liner 4 on the other side. The limiting bolt 5 will not slide out of the limiting hole 51 when it is not under tension.

[0025] When in use, the H-beam 6 needs to be pushed into the inside of the connector 1 from the side and the plastic liner 4 needs to be pushed out. When pushing, the second locking hole 62 moves to the bottom of the first plug 32 and aligns with it. If the first locking hole 61 and the second locking hole 62, the first plug 32 and the second plug 33 are the same size, the first plug 32 will fall into the second locking hole 62, so that the H-beam 6 cannot be fully pushed into place. To avoid the above situation, the diameter of the second locking hole 62 is smaller than the diameter of the first plug 32 but larger than the diameter of the second plug 33, and the diameter of the first locking hole 61 is larger than the diameter of the first plug 32. When the H-beam 6 is gradually pushed into the interior of both sides of the connector 1, the smaller diameter second locking hole 62 will move to the position below the first plastic cylinder 3 first. Since the diameter of the first plug 32 inside the first plastic cylinder 3 is larger than the inner diameter of the second locking hole 62, the first plug 32 cannot fall through the second locking hole 62 until the first locking hole 61 is aligned with the bottom of the first plastic cylinder 3 and the second locking hole 62 is aligned with the bottom of the second plastic cylinder 31, then both the first plug 32 and the second plug 33 can fall.

[0026] Finally, the surface of the connector 1 below the first plastic cylinder 3 and the second plastic cylinder 31 is provided with a screw groove 2. The first plastic cylinder 3 and the second plastic cylinder 31 are detachably connected to the surface of the connector 1 by screwing the screw into the screw groove 2. After the first plug 32 and the second plug 33 fall down, the first plastic cylinder 3 and the second plastic cylinder 31 can be rotated to remove them, so as to avoid taking up too much space.

[0027] In use, first pull the limiting bolt 5 to cause it to disengage from its outer ring, allowing the limiting bolt 5 to be removed and the locking of the plastic liners 4 on both sides to be released. The H-beams 6 on both sides can then abut against the plastic liners 4 from the side and be pushed into the interior of the H-beams 6. During this abutment, the H-beams 6 are pushed from the side closest to the first plastic cylinder 3 to the other side into the inside of the connector 1, causing the second locking hole 62 of the H-beams 6 to be pushed into the connector 1 first. Keeping the end of the H-beams 6 against the inner wall surface of the vertical portion of the connector 1, the plastic liners 4 can be gradually pushed outwards. As the H-beams 6 are pushed in, the plastic liners 4 are pushed out and no longer obstruct the bottom of the first and second bolts 32 and 33, thus releasing the smaller diameter second locking hole. The hole 62 will first move to the position below the first plastic cylinder 3. Since the diameter of the first plug 32 inside the first plastic cylinder 3 is larger than the inner diameter of the second locking hole 62, the first plug 32 cannot fall through the second locking hole 62 at this time. Until the first locking hole 61 is pushed to align with the bottom of the first plastic cylinder 3 and the second locking hole 62 is aligned with the bottom of the second plastic cylinder 31, the first plug 32 and the second plug 33 can both fall down and be inserted into the first locking hole 61 and the second locking hole 62 respectively, thus penetrating the H-beam 6 and achieving temporary self-locking of the H-beam 6. Subsequently, the bolt 7 can be used to connect the connector 1 and the H-beam 6 with the mounting hole 11 and the connecting hole 63 of the H-beam 6 to achieve a stable connection between the connector 1 and the H-beam 6 with sufficient connection strength.
