Description

Technical Field

[0001] This utility model relates to the field of bridge construction technology, specifically to a Bailey beam support mechanism. Background Technology

[0002] In the construction of cast-in-place beams for bridges at height, it is generally necessary to erect full-span scaffolding or ground-mounted steel pipe column scaffolding as a construction platform, depending on the height, location, and span of the pier. Existing construction platforms are usually connected using Bailey bridges to ensure that the stability and strength of the construction platform meet the construction requirements. For Bailey bridges located on curved sections, it is not easy for the vertical members of the Bailey bridge to be exactly located at the support points of the bridge bearings. Custom-made Bailey bridges or structural reinforcement of the Bailey bridges are required. However, custom-made Bailey bridges are expensive. If structural reinforcement of the Bailey bridges is used, due to the uneven curve angle of the Bailey bridges, it is not easy to determine the corresponding support point positions of the bridge bearings on the Bailey bridges in advance. Therefore, it is not possible to reinforce in advance, and high-altitude operations are required, which poses construction risks such as falling objects from heights. Furthermore, using fully welded or bolted connections to connect the reinforcement structure to the Bailey bridges can easily damage the Bailey bridges themselves, affecting the recycling and reuse of the Bailey bridges. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of existing technologies, such as the difficulty in aligning the vertical members of existing Bailey beams with the support points of bridge bearings, the high cost and risk of existing structural reinforcement measures, and the susceptibility to damage to Bailey beams. This invention provides a Bailey beam support mechanism.

[0004] This utility model provides a Bailey beam support mechanism, comprising: A truss structure, wherein the top of the truss structure can abut against the bottom surface of the upper chord of the Bailey beam and the bottom of the truss structure can abut against the top surface of the lower chord of the Bailey beam; The clamping mechanism includes a U-bolt and a connecting plate. The connecting plate has mounting holes adapted to the U-bolt, and the U-bolt is equipped with a locking nut. The U-bolt can clamp and connect the truss structure and the Bailey beam.

[0005] Preferably, the truss structure includes horizontal bracing members and at least three vertical bracing members. The horizontal bracing members are parallel to and abut against the bottom surface of the upper chord of the Bailey beam. One end of each vertical bracing member is connected to the bottom of the horizontal bracing member, and the other end abuts against the top surface of the lower chord of the Bailey beam. The horizontal bracing members can disperse the vertical support force, avoiding stress concentration that could cause structural deformation. The multiple vertical bracing members ensure that the middle vertical bracing member, after aligning with the support point of the bridge bearing, has additional vertical bracing members on both sides for auxiliary support, thereby improving the strengthening effect.

[0006] Preferably, a diagonal brace is provided between at least two adjacent vertical support members, and the U-bolt can securely connect the vertical support member and the diagonal brace. By providing diagonal braces, the structural strength of the truss structure can be further improved, thereby increasing its supporting strength.

[0007] Preferably, the diagonal brace connects the bottom surface of the horizontal brace and the side wall of the vertical brace to form a multi-point connected truss structure.

[0008] Preferably, the intersection of at least one of the diagonal bracing members and the vertical bracing member is located above the support point of the bridge bearing. This ensures that a reinforcing member with vertical support capability exists above the support point of the bridge bearing, thereby improving the overall support effect.

[0009] Preferably, the horizontal bracing member includes a steel profile member, and the vertical bracing member and the diagonal bracing member include steel profile members or steel pipes.

[0010] Preferably, the vertical support member is welded to the top surface of the lower chord of the Bailey beam. This improves connection stability and completely prevents the support structure from loosening during use.

[0011] Preferably, the mounting hole includes a strip-shaped hole. This allows the support structure to be appropriately positioned to ensure structural reinforcement above the support point of the bridge bearing.

[0012] Preferably, the system further includes several binding members for binding the vertical support members and the Bailey beam. By providing binding members, the stability of the support structure can be further improved.

[0013] Preferably, the binding element comprises iron wire.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model provides a Bailey beam support mechanism, which supports the Bailey beam through a truss structure, thereby improving the structural strength of the Bailey beam during use; 2. This utility model provides a Bailey beam support mechanism, which connects the truss structure and the Bailey beam through a clamping mechanism. It can achieve initial connection between the truss structure and the Bailey beam on the ground, and quick locking after a small range of position adjustment after the Bailey beam is set in place. 3. This utility model provides a Bailey beam support mechanism that is easy to install, has low risk, and can avoid damage to the Bailey beam. Attached Figure Description

[0022] The present invention will be further described in detail below with reference to specific embodiments. However, it should not be construed as limiting the scope of the present invention to the following embodiments; all technologies implemented based on the content of the present invention fall within the scope of the present invention.

[0023] Unless otherwise specified, the terms "upper," "lower," "left," "right," "center," "inner," and "outer" used in the description of specific embodiments of this utility model to indicate orientation or positional relationships are based on the orientation or positional relationships shown in the accompanying drawings, or the orientation or positional relationship in which the utility model product / equipment / device is usually placed during use. These terms are merely for the purpose of facilitating the description of the utility model solution or simplifying the description in specific embodiments, and for enabling those skilled in the art to quickly understand the solution, and do not indicate or imply that a specific device / component / element must have a specific orientation, or be constructed and operated in a specific positional relationship. Therefore, they should not be construed as limitations on this utility model.

[0024] Furthermore, the use of terms such as "horizontal," "vertical," "suspended," "parallel," and "coaxial" does not imply that the corresponding device / component / element must be absolutely horizontal, vertical, suspended, parallel, or coaxial. Slight tilt or deviation is permissible, as long as it does not affect the normal function of the relevant component. For example, "horizontal" simply means that its direction is more horizontal relative to "vertical," not that the structure must be perfectly horizontal; a slight tilt is acceptable. "Coaxial" means that two components are arranged as coaxially as possible, allowing them to move coaxially or approximately coaxially when their relative positions change. Alternatively, it can be simplified to mean that the corresponding device / component / element, when arranged in "horizontal," "vertical," "suspended," "parallel," or "coaxial" directions, can have an error / deviation of ±10% relative to the corresponding direction, more preferably within ±8%, more preferably within ±6%, more preferably within ±5%, and more preferably within ±4%. For example, the deviation in the "coaxial" direction is controlled within 0.2-1mm, preferably within 0.2-0.5mm. As long as the corresponding device / component / element is within the error / deviation range, it can still achieve its function in the present invention.

[0025] Furthermore, the use of terms such as "first," "second," and "third" in terminology is merely for distinguishing descriptions of identical or similar components and should not be interpreted as emphasizing or implying the relative importance of a particular component.

[0026] Furthermore, in the description of the embodiments of this utility model, "several", "multiple", and "several" represent at least two. The number can be any number, such as two, three, four, five, six, seven, eight, or nine, and can even exceed nine.

[0027] Furthermore, in the description of the technical solution of this utility model, unless otherwise explicitly specified / limited / restricted, the terms "set up," "install," "connect," "link," "provided with," "laid out," and "arranged" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to common connection methods in the art, such as welding, riveting, bolting, and threaded connections. Such connections can be mechanical, electrical, or communication connections; they can be direct connections or indirect connections through an intermediate medium; and they can refer to the internal communication between two components.

[0028] Example 1 like Figures 2-3 As shown, a Bailey beam support mechanism includes a truss structure and a clamping mechanism. The truss structure includes one horizontal brace 4, three vertical braces 5, and one diagonal brace 6.

[0029] The horizontal bracing member 4 is used to abut against the bottom surface of the upper chord member 1001 of the Bailey beam 100 in parallel, so as to disperse the vertical force of the support structure on the Bailey beam 100, avoid stress concentration, and improve the stability of the support structure.

[0030] The vertical bracing member 5 is used to provide vertical support. The top of the vertical bracing member 5 is welded to the bottom of the horizontal bracing member 4, and the bottom can abut against the top surface of the lower chord member 1002 of the Bailey beam 100.

[0031] The clamping mechanism is used to hold and fix the truss structure to the Bailey beam 100, so as to realize the rapid and non-destructive installation of the truss structure on the Bailey beam 100.

[0032] The diagonal bracing member 6 is used to strengthen the structure between two adjacent vertical bracing members 5 and to effectively distribute the vertical force on the Bailey beam 100.

[0033] In an optional embodiment, the clamping mechanism includes a U-bolt and a connecting plate 2. The connecting plate 2 is provided with mounting holes 21 that are adapted to the U-bolt. The U-bolt is equipped with a locking nut 3. The U-bolt can hold the connecting truss structure and Bailey beam 100.

[0034] When using, such as Figure 4 As shown, the U-bolts can be clamped at appropriate positions on the vertical support member 5 and the Bailey beam 100, and fixed by locking the nut 3. This allows for preliminary fixing of the support structure on the Bailey beam 100 on the ground in advance. After the Bailey beam 100 is installed in place, a small range of positional adjustments are made before locking, which can reduce the installation risk of adding the support structure at high altitude.

[0035] In an optional embodiment, the U-bolt can simultaneously hold the vertical support member 5 and the diagonal support member 6, and the connecting plate 2 is attached to one side of the vertical support member 5 and the diagonal support member 6, which can achieve a stable connection between the support structure and the Bailey beam 100.

[0036] In an optional embodiment, the vertical support member 5 can be spot-welded to the top surface of the lower chord member 1002 of the Bailey beam 100 to improve the stability of the support.

[0037] In an optional embodiment, the diagonal brace 6 connects the bottom surface of the horizontal brace 4 and the side wall of the vertical brace 5. In use, four support nodes are formed on the bottom surface of the horizontal brace 4 and three support nodes are formed on the top surface of the lower chord 1002 of the Bailey beam 100. This allows the vertical force on the Bailey beam 100 to be transmitted along the diagonal brace 6 to the horizontal brace 4 for dispersion, avoiding stress concentration and improving structural stability.

[0038] In optional implementations, such as Figures 5-6As shown, the intersection of the diagonal brace 6 and the vertical brace 5 is located above the support point 200 of the bridge bearing. The intersection can be aligned with the support point 200 of the bridge bearing by adjusting the position of the support structure along the transverse direction of the Bailey beam 100. This allows for the direct vertical transmission of the relevant vertical forces between the bridge bearing and the Bailey beam 100, improving the supporting and strengthening effect of the support structure on the Bailey beam 100.

[0039] In an optional embodiment, the horizontal bracing member 4 can be a steel member made of channel steel, I-beam, or angle steel, and the vertical bracing member 5 and the diagonal bracing member 6 can be steel members or steel pipes.

[0040] In an optional embodiment, the mounting hole 21 can be a strip hole, and the long axis of the strip hole can be set laterally parallel to the length direction of the cross brace 4, so that the clamping range of the clamping mechanism is wider. After the support structure is set, the position of the support structure in the lateral direction of the Bailey beam 100 can be adjusted within a certain range according to the actual situation, so as to ensure that the support structure can effectively support the support point 200 of the bridge bearing.

[0041] In an optional embodiment, the long axis of the mounting hole 21 may also have a certain width to expand the movable range of the connecting plate 2 relative to the Bailey beam 100, thereby realizing the position adjustment range of the support structure relative to the Bailey beam 100.

[0042] In one or more implementations, such as Figure 2 , Figure 3 As shown, several binding members 7 can also be set. The binding members 7 are used to bind the vertical support members 5 and the Bailey beam 100 to ensure the connection stability between the support structure and the Bailey beam 100 before and after locking, avoid the risk of the support structure falling off, and ensure construction safety.

[0043] In an optional embodiment, the binding element 7 can be iron wire, which can be easily installed and removed, enabling rapid connection between the support structure and the Bailey beam 100.

[0044] In an optional implementation, the binding members 7 can be arranged in multiple ways according to the actual situation.

[0045] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
