Technical Field

[0001] This utility model relates to the field of main beam installation technology, and in particular to an inner-lined main beam connection mechanism. Background Technology

[0002] An internally lined main girder connection mechanism is an engineering construction used to enhance the stability and load-bearing capacity of a main girder structure. This connection mechanism is commonly used in bridges, buildings, or other large structures to ensure a secure connection between the main girder and other structural components. Below are some key characteristics and considerations for internally lined main girder connection mechanisms. The specific design and application of internally lined main girder connection mechanisms will vary depending on the specific needs of the project and environmental conditions. Engineers will conduct detailed structural analysis and design based on these factors to ensure the stability and safety of the entire structure.

[0003] However, during the implementation of the above technical solution, at least the following technical problems were discovered:

[0004] 1. The inner lining connection mechanism should be easy to inspect and maintain regularly to ensure the long-term stability and safety of the structure. In structures such as bridges, the inner lining main beam connection mechanism should have good waterproof performance to prevent water intrusion and structural damage.

[0005] 2. The on-site installation of the main beam connection mechanism is difficult to control and needs to be controlled during the design phase. Therefore, we propose an inner-lined main beam connection mechanism. Utility Model Content

[0007] To address the shortcomings of existing technologies, this utility model provides an inner-lined main beam connection mechanism, solving the technical problems of docking accuracy and stability.

[0008] (II) Technical Solution

[0009] To achieve the above objectives, this utility model provides the following technical solution:

[0010] An internally lined main beam connection mechanism includes a first structural block and a second structural block, with a docking compartment provided in the middle of the first and second structural blocks. The main beam is fixedly installed in the first and second structural blocks via slots and locked in place by locking bolts.

[0011] In addition, two sets of transverse connecting blocks are provided between the first structural block and the second structural block. The first structural block and the second structural block are fixed and locked by passing locking pins through the transverse connecting blocks, so as to fix and snap the two sets of main beams.

[0012] Preferably, push rods are provided on the sides of the first and second structural blocks. The push rods are used to install and connect the first and second structural blocks, which facilitates horizontal advancement. In addition, the push rods can be connected to external mechanical advancement equipment by bolts to assist in horizontal advancement.

[0013] Preferably, the first structural block is provided with an upper protective sleeve at the upward position and a lower protective sleeve at the downward position, and the locking bolt is an inwardly tapered guide plate with an opening facing downward, which diverts and discharges rainwater from the surface of the first structural block.

[0014] Preferably, a cover plate is provided at the upper opening of the upper protective sleeve to seal the upper protective sleeve. The upper protective sleeve has a buckle at the joint to facilitate the detachable installation of the cover plate. The cover plate is an arc-shaped plate with a central protrusion to facilitate the drainage of water flow from above. This comprehensively achieves rust prevention and protection for the locking bolts. Combined with the use of highly rust-resistant stainless steel material, the stability of the locking mechanism is further improved.

[0015] Preferably, the internal structures of the first structural block and the second structural block are the same. The following description will take the first structural block as an example. The first structural block is provided with a main beam positioning groove, and a stepped groove is provided at the bottom of the main beam positioning groove to control the end shape of the main beam.

[0016] Preferably, the main beam positioning groove has a tapered structure on its side, which can provide some guidance for the installation of the main beam and improve the ease of installation.

[0017] Preferably, the horizontal docking block consists of two sets of positioning blocks arranged horizontally on opposite sides of the first and second structural blocks, while the vertical docking block consists of two sets of positioning blocks arranged vertically on opposite sides of the first and second structural blocks, thereby comprehensively achieving adjustment of the point position accuracy in both the horizontal and vertical directions.

[0018] Preferably, the horizontal docking block is provided with a docking positioning groove at the corresponding position, so that the horizontal docking block and the vertical docking block are inserted into the position to cooperate and better control the installation accuracy.

[0019] (III) Beneficial Effects

[0020] 1. The first structural block is equipped with an upper protective sleeve at the upward position and a lower protective sleeve at the downward position. The locking bolt is an inwardly tapered guide plate with an opening facing downward, which diverts rainwater from the surface of the first structural block. The upper protective sleeve has a buckle at the joint, which facilitates the detachable installation of the cover plate. The cover plate is an arc-shaped plate with a central protrusion, which facilitates the drainage of water from above. This comprehensive system provides rust protection for the locking bolt. Combined with the use of highly rust-resistant stainless steel, the stability of the locking mechanism is further improved.

[0021] 2. The accuracy of the docking position of the two sets of main beams also needs to be achieved through the structural design of the horizontal docking blocks and the vertical docking blocks. The horizontal docking blocks are two sets of positioning blocks set horizontally on the opposite side of the first and second structural blocks. The vertical docking blocks are two sets of positioning blocks set vertically on the opposite side of the first and second structural blocks. This combination allows for the adjustment of the point position accuracy in both the horizontal and vertical directions.

[0028] This application provides an internally lined main beam connection mechanism to solve the problem of installation accuracy control in the prior art. The transverse docking block consists of two groups of positioning blocks arranged horizontally on opposite sides of the first and second structural blocks. The vertical docking block consists of two groups of positioning blocks arranged vertically on opposite sides of the first and second structural blocks. This mechanism comprehensively achieves the adjustment of point position accuracy in both the horizontal and vertical directions.

[0029] Example 1

[0030] The technical solution in this application embodiment is to solve the above-mentioned problem of installation accuracy control, and the overall idea is as follows:

[0031] To address the problems existing in the prior art, this utility model provides an inner-lined main beam connection mechanism, including...

[0032] A first structural block 1 and a second structural block 2 are provided with a docking compartment in the middle of the first structural block 1 and the second structural block 2. The main beam is fixedly installed in the first structural block 1 and the second structural block 2 through a slot and locked in place by locking bolts 7.

[0033] In addition, two sets of transverse connecting blocks 3 are provided between the first structural block 1 and the second structural block 2. The first structural block 1 and the second structural block 2 are fixed and locked by passing the locking pins 5 through the transverse connecting blocks 3, so as to achieve the fixation and snap-fit ​​of the two sets of main beams.

[0034] Push rods 6 are provided on the sides of the first structural block 1 and the second structural block 2. The push rods 6 are used to install and connect the first structural block 1 and the second structural block 2, which facilitates horizontal advancement. In addition, the push rods 6 can be connected to external mechanical advancement equipment by bolts to assist in horizontal advancement.

[0035] The installation and use of the main beam requires a long period of time for initial fixing. Subsequent use may lead to structural failure due to moisture intrusion and damage. The first structural block 1 is equipped with an upper protective sleeve 8 at the upward position and a lower protective sleeve 11 at the downward position. The locking bolt 7 is an inwardly tapering guide plate with a downward opening, which diverts rainwater from the surface of the first structural block 1.

[0036] In addition, a cover plate 12 is provided at the upper opening of the upper protective sleeve 8 to seal the upper protective sleeve 8. The upper protective sleeve 8 has a buckle at the joint to facilitate the detachable installation of the cover plate 12. The cover plate 12 is an arc-shaped plate with a central protrusion to facilitate the drainage of water flow from above. This comprehensively achieves rust prevention and protection for the locking bolt 7. Combined with the use of highly rust-resistant stainless steel material, the stability of the locking mechanism is further improved.

[0037] The installation of the main beams requires not only ensuring the stability of the connection, but also the precision of the docking between the two sets of main beams. Precision control involves the installation depth of the main beams and the positional accuracy of the multiple docking positions.

[0038] The installation depth of the main beam is controlled by the depth to which the main beam is inserted into the first structural block 1 and the second structural block 2. The internal structures of the two sets of first structural blocks 1 and second structural blocks 2 are the same. The following description takes the first structural block 1 as an example. The first structural block 1 is provided with a main beam positioning groove 9. The bottom of the main beam positioning groove 9 is provided with a stepped groove to control the end shape of the main beam. In addition, the side of the main beam positioning groove 9 is provided with a tapered structure, which can provide a certain guidance for the installation of the main beam and improve the convenience of installation.

[0039] The accuracy of the docking position of the two sets of main beams also needs to be achieved through the structural design of the horizontal docking block 3 and the vertical docking block 4. The horizontal docking block 3 consists of two sets of positioning blocks arranged horizontally on the opposite sides of the first structural block 1 and the second structural block 2. The vertical docking block 4 consists of two sets of positioning blocks arranged vertically on the opposite sides of the first structural block 1 and the second structural block 2. This combination enables the adjustment of the point position accuracy in both the horizontal and vertical directions. The horizontal docking block 3 is provided with a docking positioning groove 10, which allows the horizontal docking block 3 and the vertical docking block 4 to be inserted into the correct positions for better control of the installation accuracy.

[0040] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
