Description

Technical Field

[0001] This utility model relates to a reinforcing connector for Bailey panels. Background Technology

[0002] In modern engineering and construction, Bailey panels, as a key prefabricated component, are widely used in the construction of bridges, towers, and large scaffolding structures. Their unique triangular truss structure gives Bailey panels advantages such as light weight, high load-bearing capacity, and ease of assembly and disassembly, enabling them to quickly meet the needs of construction sites for temporary support and load-bearing structures. However, with the continuous expansion of project scale and increasingly stringent construction requirements, Bailey panels face some pressing problems in practical applications.

[0003] Traditional Bailey bridge panel connections primarily rely on basic methods such as pin joints and bolt connections. While these methods can meet the assembly requirements of Bailey bridge panels to a certain extent, they are prone to loosening under heavy loads, posing serious safety hazards. Furthermore, the connections have poor stability, making it difficult to effectively control the relative displacement between Bailey bridge panels, which affects the accuracy and reliability of the entire structure, reducing construction quality and service life. In addition, traditional connectors are complex to operate, requiring various tools for installation and disassembly, which is time-consuming and labor-intensive, making it difficult to meet the requirements of rapid construction and increasing construction costs and timelines.

[0004] Therefore, a reinforcing connector for Bailey panels is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide a reinforcing connector for Bailey panels to solve the problems mentioned in the background art, such as the tendency for traditional Bailey panel connections to become loose and the poor stability of the connection.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a reinforcing connector for Bailey panels, comprising two sets of Bailey panels, wherein the two sets of Bailey panels are connected by a connecting component.

[0007] Both sides of the Bailey sheet are provided with inner grooves for connecting components to pass through.

[0008] The connecting component connects the two sets of Bailey plates through the inner groove.

[0009] Preferably, the connecting assembly includes a connecting bolt rod passing through the two sets of inner grooves, with a hexagonal bolt provided on the outer periphery of the connecting bolt rod, and two sets of fixing plates provided at the distance between the hexagonal bolt and the side wall of the connecting bolt rod.

[0010] Preferably, the angle between the two sets of fixed support plates and the connecting bolts is 45 degrees, and the width of the fixed support plate matches the groove of the Bailey plate side wall so that the fixed support plate abuts against the Bailey plate side wall.

[0011] Preferably, the connecting bolt has an external thread on the outer periphery of the hexagonal bolt side, so that the connecting bolt can rotate relative to the hexagonal bolt through the external thread.

[0012] Preferably, a positioning groove is provided at the inner groove, and a positioning support plate is provided inside the positioning groove. The positioning support plate is connected to the Bailey sheet by fixing bolts.

[0013] The inner side of the positioning support plate is provided with an arc-shaped groove that mates with the connecting bolt, so that the positioning support plate can be connected to the outer periphery of the connecting bolt through the positioning groove.

[0014] Preferably, one side of the positioning support plate is provided with a hook hole for hooking the hook rod, so that the hook rod can hook the positioning support plate away from the positioning groove through the hook hole.

[0015] Preferably, a bolt plate is provided on the side of the connecting bolt rod away from the external thread, and a tight spring is provided on the outer periphery of the connecting bolt rod, with the tight spring located between the bolt plate and the positioning support plate.

[0016] Preferably, the outer diameter of the connecting bolt is smaller than the inner diameter of the inner groove, so that the connecting bolt is connected between the two sets of Bailey plates through the inner groove.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] This utility model generates preload through a tight spring and a fixed support plate, which effectively prevents the connecting bolt from loosening during use, enhances the reliability of the connection, adapts to complex working conditions such as heavy loads, and ensures engineering safety.

[0019] The fixed support plate is in close contact with the side wall of the Bailey panel, generating sufficient friction and support force to effectively control the relative displacement between the Bailey panels, improve the accuracy and reliability of the entire structure, and extend its service life.

[0020] During installation, no complicated tools are required. The hexagonal bolts can be moved linearly along the connecting bolt rod by rotating the bolt plate to complete the initial fixation. During disassembly, after releasing the fixing bolts, the positioning support plate can be moved with a hook rod to loosen the hexagonal bolts and pull out the connecting bolt rod. The whole process is simple and quick, saving time and labor costs and meeting the requirements of rapid construction.

[0021] The tight spring design not only provides preload but also mitigates shocks and vibrations experienced by the connector during use, reducing wear and tear and extending its service life.

[0022] The easy installation and disassembly of the connectors make the assembly and disassembly of Bailey panels more flexible, allowing for quick structural adjustments according to actual construction needs, improving construction efficiency, and better adapting to dynamic changes at the construction site.

[0030] To address the problems of loose connections and poor stability in traditional Bailey bridge panel connections, this invention provides a reinforcing connector for Bailey bridge panels. The technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this invention, not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0031] Please see Figure 1-6This utility model provides a reinforcing connector for Bailey bridge sections, comprising two sets of Bailey bridge sections 1, which are connected by a connecting assembly 2. The connecting assembly 2 includes a connecting bolt 201 passing through the two sets of inner grooves 101. A hexagonal bolt 202 is provided on the outer periphery of the connecting bolt 201. Two sets of fixing plates 203 are provided at a distance of 45 degrees from the sidewall of the connecting bolt 201. The width of the fixing plates 203 and the connecting bolts form a 45-degree angle, and the width of the fixing plates 203 matches the groove on the sidewall of the Bailey bridge section 1, so that the fixing plates 203 abut against the sidewall of the Bailey bridge section 1. An external thread 2011 is provided on the outer periphery of the connecting bolt 201 on the side of the hexagonal bolt 202, allowing the connecting bolt to rotate relative to the hexagonal bolt 202 through the external thread 2011. A positioning groove 102 is provided at the inner groove 101, and a positioning support plate 204 is provided inside the positioning groove 102. The positioning support plate 204 is connected to the Bailey plate 1 by fixing bolts. An arc-shaped groove 2041 is provided on the inner side of the positioning support plate 204 to cooperate with the connecting rod 201, so that the positioning support plate 204 is connected to the outer periphery of the connecting rod 201 through the positioning groove 102. A hook hole 2042 is provided on one side of the positioning support plate 204 for hooking the hook rod, so that the hook rod can hook the positioning support plate 204 away from the positioning groove 102 through the hook hole 2042. A bolt plate 205 is provided on the side of the connecting rod 201 away from the external thread 2011, and a tight spring 206 is provided on the outer periphery of the connecting rod 201, and the tight spring 206 is located between the bolt plate 205 and the positioning support plate 204.

[0032] Both sides of the Bailey plate 1 are provided with inner grooves 101 for the connecting component 2 to pass through. The outer diameter of the connecting rod 201 is smaller than the inner diameter of the inner groove 101, so that the connecting rod 201 passes through the inner groove 101 and connects between the two sets of Bailey plates 1.

[0033] The connecting component 2 connects the two sets of Bailey sheets 1 through the inner groove 101.

[0034] The working principle of the Bailey plate reinforcement connector provided by this utility model is as follows: two sets of Bailey plates 1 are placed side by side, and the tight spring 206 is sleeved on the outer periphery of the connecting bolt 201 and moved towards the bolt plate 205 until it moves to the position of the bolt plate 205.

[0035] Pick up the connecting rod 201 from the connecting assembly 2 and align it with the entrance of the inner groove 101 of the Bailey plate 1. Smoothly insert the connecting rod 201 along the direction of the inner groove 101, with both ends of the connecting rod 201 located on both sides of the inner groove 101 of the two sets of Bailey plates 1.

[0036] Pick up the positioning support plate 204 and align its inner arc-shaped groove 2041 with the portion of the connecting bolt 201 located inside the Bailey bridge section 1. Then, smoothly press the positioning support plate 204 into the positioning groove 102 until it is fully embedded and tightly fitted with the Bailey bridge section 1. To ensure the secure installation of the positioning support plate 204, it can be further secured to the Bailey bridge section 1 using fixing bolts. The fixing bolts pass through the bolt holes on the positioning support plate 204 and are screwed into the pre-set threaded holes in the Bailey bridge section 1, thereby firmly fixing the positioning support plate 204 in the positioning groove 102 of the Bailey bridge section 1.

[0037] Install the hex bolt 202 onto one end of the connecting rod 201. Hold the hex bolt 202 and rotate the bolt plate 205 of the connecting rod 201. The bolt plate 205 drives the connecting rod 201 to rotate. The connecting rod 201 drives the hex bolt 202 to move linearly along the connecting rod 201 through the external thread 2011, so that it screws in along the external thread 2011 on the outer periphery of the connecting rod 201.

[0038] As the hex bolt 202 is screwed in, it will cause the two sets of fixed support plates 203 to gradually move closer to the side wall of the Bailey bridge 1. Since the angle between the fixed support plate 203 and the connecting bolt is 45 degrees, and the width of the fixed support plate 203 matches the groove of the side wall of the Bailey bridge 1, when the hex bolt 202 is screwed in to a certain extent, the fixed support plate 203 will tightly abut against the side wall of the Bailey bridge 1.

[0039] At this point, continue rotating the bolt plate 205 to control the hexagonal bolt 202 to continue moving, so as to ensure that sufficient friction and support force are generated between the fixed support plate 203 and the side wall of the Bailey plate 1, thereby initially fixing the two sets of Bailey plates 1 together.

[0040] As the bolt plate 205 rotates, it moves toward the tightening spring 206, compressing the tightening spring 206. The tightening spring 206 generates a corresponding force, causing the connecting bolt 201 to generate a preload during use, thus preventing the connecting bolt 201 from loosening during use.

[0041] When it is necessary to disassemble the Bailey panel 1 reinforcement connector, first release the fixing bolts securing the positioning support plate 204. Then, use a hook rod through the hook hole 2042 on one side of the positioning support plate 204 to hook the positioning support plate 204 away from the positioning groove 102. After the hook rod is inserted into the hook hole 2042, use appropriate pulling and prying force to disengage the positioning support plate 204 from the positioning groove 102. At this time, the tension spring 206 elastically elongates through the inner groove 101, releasing the preload on the connecting bolt 201. Next, loosen the hexagonal bolt 202 to unscrew it from the connecting bolt 201. Finally, pull the connecting bolt 201 out of the inner groove 101 of the Bailey panel 1, completing the entire disassembly process of the connector. The entire disassembly process is simple and quick, requiring no complicated tools, greatly improving construction efficiency.

[0042] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
