[0002] In bridge construction, steel pipe scaffolding is a common support system suitable for various construction scenarios such as cast-in-place beam construction, pier construction, and steel box girder hoisting. It has the advantages of high load-bearing capacity, good stability, and flexible erection. A typical scaffolding system generally includes a pre-set base and columns welded to the pre-set base.

[0003] The inventors discovered that the current practice of directly welding the column to the pre-reserved base has problems such as stress concentration in the bracket, inability to adjust, and inconvenience in disassembly and assembly, resulting in low applicability and low construction efficiency of the bracket. Utility Model Content

[0004] The purpose of this invention is to provide a bracket and support system that can improve the current brackets' low applicability and low construction efficiency.

[0005] The embodiments of this utility model can be implemented as follows:

[0008] An adjustable hinge support is provided on the preset base and snapped into the receiving space; the column is connected to the adjustable hinge support.

[0009] A connector is provided at the top of the column to support the structure to be supported.

[0010] In an optional embodiment, the preset base is configured as a combination of a precast concrete foundation and pre-embedded anchor bolts, and a supporting steel plate is provided on the preset base. The supporting baffle and the adjustable hinge support are disposed on the supporting steel plate.

[0011] In an optional embodiment, the side of the support baffle facing the receiving space is covered with a layer of high-damping material.

[0012] In an optional embodiment, the adjustable hinge support is capable of swinging within a range of ±1.5° relative to the vertical direction.

Detailed Implementation

[0029] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0030] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0031] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0032] In the description of this utility model, it should be noted that if terms such as "upper," "lower," "inner," or "outer" are used to indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship that the utility model product is usually placed in during use, they are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0033] Furthermore, the terms "first" and "second" are used only to distinguish descriptions and should not be interpreted as indicating or implying relative importance.

[0034] It should be noted that, where there is no conflict, the features in the embodiments of this utility model can be combined with each other.

[0035] In bridge construction, steel pipe scaffolding is a common support system, suitable for various construction scenarios such as cast-in-place beam construction, pier construction, and steel box girder hoisting. Especially during the hoisting construction of large steel box girder bridges, temporary scaffolding is needed to support each sub-block and segment, which are then installed and welded together using lifting equipment to finally complete the entire steel box girder construction process.

[0036] Currently, conventional brackets generally include a pre-set base and a column welded to the pre-set base. However, if the column is directly welded to the pre-set base, it will cause stress concentration at the connection between the column and the pre-set base, and the column cannot be adjusted or is inconvenient to disassemble and assemble.

[0037] To address the aforementioned technical problems, this utility model provides a bracket and support system to improve the stress concentration at the connection between the column and base of current brackets, as well as the inability to adjust the column and the inconvenience of assembly and disassembly. The overall structure, working principle, and technical effects of the bracket and support system provided by this utility model are described in detail below through embodiments and accompanying drawings.

[0038] Please refer to Figure 1 and Figure 2 On the one hand, this utility model provides a support system that can be applied to various construction scenarios such as cast-in-place beam construction, bridge pier construction, and steel box girder hoisting construction, in order to support and reinforce cast-in-place beams and steel box girders awaiting support structures, thereby facilitating construction.

[0039] This utility model provides a support system comprising a plurality of supports 100. In this embodiment, to connect the supports 100 in the support system, multiple connecting rods 200 are detachably installed between adjacent supports 100. The connecting rods 200 are made of No. 18 channel steel, and the channel steel is detachably connected to the supports 100 by high-strength bolts. In some alternative embodiments, the connecting rods 200 may also be telescopic steel beams, with hydraulic locking devices at both ends to enhance the overall rigidity of the support system.

[0040] Furthermore, in order to improve the overall structural stability of the support system, multiple diagonal braces 300 are installed between adjacent supports 100. The two ends of the diagonal braces 300 are connected to the ends of two adjacent connecting rods 200, so that the diagonal braces 300 and the connecting rods 200 form multiple triangular frame support and reinforcement structures between adjacent supports 100, thereby improving the overall structural stability of the support system.

[0041] It is understood that the number of supports 100 in the support system can be adaptively selected according to the actual working conditions and load. Commonly used support systems may include two supports 100, three supports 100, or four supports 100. In other embodiments, the support system may also be configured to include other numbers of supports 100 depending on the working conditions.

[0042] Please refer to Figure 3 To facilitate the disassembly and installation of the support system, in this embodiment, the diagonal brace 300 includes an adjustable rod 310 and a helical adjustment section 320. One end of the adjustable rod 310 is hollow and has an internal thread. The surface of the helical adjustment section 320 has a thread that matches the adjustable rod 310, so the thread of the helical adjustment section 320 passes through the adjustable rod 310. By adjusting the length of the helical adjustment section 320 within the adjustable rod 310, the length of the diagonal brace 300 can be adjusted, thereby adapting to support systems of different specifications and improving applicability. In some alternative embodiments, the diagonal brace 300 can also adopt a structure with a telescopic rod, such as a telescopic hydraulic cylinder or a telescopic pneumatic cylinder, to provide stable support while facilitating the adjustment of the length of the diagonal brace 300.

[0043] On the other hand, please refer to Figures 4-6 This utility model provides a bracket 100, which is applied to the aforementioned support system. Several brackets 100 are connected to form a support system to provide support and reinforcement for cast-in-place beams, steel box girders, and other structures requiring support. The bracket 100 provided by this utility model has the advantages of avoiding stress concentration, adjustable angle, and easy assembly and disassembly.

[0044] Please refer to Figure 4 and Figure 5 The support 100 provided by this utility model includes a pre-set base 110 and a column 120. The pre-set base 110 adopts a combination of precast concrete bearing and pre-embedded anchors. Under the premise of meeting the foundation bearing capacity requirements, the overall height of the pre-set base 110 can also be dynamically adjusted according to the spatial height. The support 100 also includes a support baffle 130, an adjustable hinge support 140, and a connector 150. A support steel plate 111 is detachably installed on the top of the pre-set base 110. Multiple support baffles 130 are spaced apart on the support steel plate 111, and the multiple support baffles 130 together form an accommodating space. In this embodiment, four support baffles 130 are equally spaced. The adjustable hinge support 140 is installed on the support steel plate 111 and is located within the accommodating space formed by the multiple support baffles 130. The lower end of the column 120 is connected to the adjustable hinge support 140. The connector 150 is installed on the top of the column 120 and is used to abut against the structure to be supported.

[0045] By setting multiple support baffles 130 on the base and setting adjustable hinge supports 140 between the multiple support baffles 130, the column 120 is connected to the adjustable hinge supports 140, so that the column 120 is inserted into the receiving space between the multiple baffles. By adjusting the angle of the adjustable hinge supports 140, the tilt angle of the column 120 can be adjusted. Compared with the traditional design where the column 120 is directly welded to the base, the bracket 100 provided by this utility model is easy to install and disassemble, and the angle of the column 120 is adjustable, which improves the applicability and construction efficiency of the bracket 100.

[0046] It is understood that the support 100 provided by this utility model can be applied to different working conditions. In this embodiment, the structure to be supported that abuts against the connector 150 can be a cast-in-place beam or steel box girder in bridge construction, a beam or slab or formwork in building construction, a heavy decorative component in interior decoration, or a large equipment in industrial equipment maintenance. Therefore, the support 100 provided by this utility model can be widely used in application scenarios that require temporary support structures.

[0047] Please refer to Figure 5 In this embodiment, the angle of the adjustable hinge support 140 can be adjusted. The adjustable hinge support 140 can swing within a range of ±1.5° off the vertical direction, thereby adjusting the tilt angle of the column 120 and achieving the effect of facilitating the adjustment of the tilt angle of the column 120. The adjustable hinge support 140 adopts an existing hinge support structure, and the adjustment of the angle of the adjustable hinge support 140 is achieved through its internal structure.

[0048] Please refer to Figure 5 In this embodiment, a high-damping material layer 160 is provided on the side of the multiple support baffles 130 facing the accommodating space. In this embodiment, the high-damping material layer 160 is a rubber pad layer. By providing the high-damping material layer 160 between the support baffles 130 and the columns 120, the high-damping material layer 160 can provide corresponding deformation compensation when the steel structure undergoes elastic deformation, the base undergoes settlement deformation, or the columns 120 and support baffles 130 undergo stress deformation during construction, so as to avoid stress concentration in the support 100 and affect its service life.

[0049] Please refer to Figure 6In some optional embodiments, the connector 150 includes an adjustable section 151, a telescopic member 152, and an abutment plate 153. The adjustable section 151 is movably disposed at the end of the column 120 along its length. The telescopic member 152 is disposed at the end of the adjustable section 151, and the abutment plate 153 is disposed at the end of the telescopic member 152 away from the column 120. The adjustable section 151 is used to adjust the length of the column 120 over a wide range. The telescopic member 152 is a hydraulic cylinder used to fine-tune the length of the column 120 so that the abutment plate 153 can tightly abut against the structure to be supported, ensuring good support for the column 120. In this embodiment, the abutment plate 153 is a 12mm steel plate, and a high-damping material layer 160 is also covered on the side of the abutment plate 153 away from the column 120.

[0050] It is understandable that by setting a high-damping material layer 160 on the support baffle 130 and the abutment plate 153, the collision vibration between steel structures can be reduced, thereby reducing construction noise to a certain extent.

[0051] Please refer to Figure 2 and Figure 4 The column 120 includes multiple sequentially connected connecting segments, which are detachably connected to each other. In this embodiment, a pin-type quick-connect structure is used between adjacent connecting segments, along with anti-loosening nuts and elastic washers, to achieve rapid assembly of the column 120.

[0052] In summary, the implementation principle of the bracket and support system provided by this utility model is as follows: multiple support baffles 130 are set on the base, and adjustable hinge supports 140 are set between the multiple support baffles 130. The column 120 is connected to the adjustable hinge supports 140, so that the column 120 is inserted into the receiving space between the multiple baffles. The tilt angle of the column 120 can be adjusted by adjusting the angle of the adjustable hinge supports 140. Compared with the traditional design where the column 120 is directly welded to the base, the bracket 100 provided by this utility model is easy to install and disassemble, and the angle of the column 120 is adjustable, which improves the applicability and construction efficiency of the bracket 100.

[0053] The above description is only a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
