Abstract
Description
Technical Field
[0001] This utility model relates to the field of flange plate support technology, specifically an adjustable flange plate integral support. Background Technology
[0002] Flange plate supports are temporary support components in steel structure engineering. They are mainly used for positioning and fixing the flange plates of H-beams, I-beams, or box girders during welding, assembly, or hoisting. They are made of angle steel, channel steel, etc., welded into triangular or L-shaped supports and directly fixed to the web plate or working platform. They are widely used in various construction and other industries.
[0003] Upon investigation, a Chinese utility model patent discloses a support for the flange plate of a cast-in-place box girder (publication number: CN213772991U), which includes several arc-shaped frame units. Adjacent arc-shaped frame units are connected by crossbeams. Each arc-shaped frame unit includes an upper chord and a lower chord. An arc-shaped rod is provided at the right end of the upper chord, and the arc-shaped rod is connected to the lower chord through a connecting rod.
[0004] In the aforementioned patent, although compared with existing technologies, the formwork support includes several arc-shaped frame units, which are integrated and reusable, the flange plate support is reasonably designed, and the flange plate line is easy to control; uprights and diagonal braces are provided between the upper and lower chords to enhance the support strength of the formwork support; the arc-shaped frame units are made of common materials and have simple structures, making them easy to manufacture, some problems still exist. For example, the angle of the support cannot be adjusted according to the different angles of the web of the specific cast-in-place box girder, resulting in the need to process multiple models of flange plate supports due to the variable angle of the web of the cast-in-place beam, thus wasting manpower and resources, greatly increasing material consumption, and indirectly reducing the project progress.
[0005] Therefore, this utility model provides an adjustable flange plate integral bracket to solve the above problems. Utility Model Content
[0006] This utility model provides an adjustable flange plate integral bracket, which aims to solve the problems mentioned in the background art.
[0007] To achieve the above objectives, this utility model provides the following technical solution: an adjustable flange plate integral support, including a lower chord, a vertical support rod fixedly connected to the top of the lower chord, an upper chord fixedly connected to the top of the vertical support rod, a web plate diagonal brace rotatably connected to one side inside the lower chord, adjustable bolts provided at the connection points between the web plate diagonal brace and the upper chord, bolt sleeves threaded onto the outer surface of the adjustable bolts, a web plate diagonal brace provided on the outer wall of the lower chord, a movable hinge connecting the top of the web plate diagonal brace to the outer wall of the web plate diagonal brace, a movable fastener movably connected to the bottom of the web plate diagonal brace to the outer wall of the lower chord, and an adjustment mechanism provided at the bottom of the lower chord.
[0008] As a preferred technical solution of this application, the adjustment mechanism includes a contact base disposed below the lower chord, and a support leg is fixedly connected to the bottom of the contact base.
[0009] As a preferred technical solution of this application, a connecting rod is slidably connected inside the contact base, and one end of the connecting rod near the contact base is fixedly connected to the bottom of the contact base.
[0010] As a preferred technical solution of this application, the top of the contact base is fixedly connected to a first spring on the outer ring of the connecting rod, and the end of the first spring away from the contact base is fixedly connected to the bottom of the lower chord rod.
[0011] As a preferred technical solution of this application, the top of the lower chord is slidably connected to a plug block, and the outer wall of the contact base is provided with a plurality of plug holes for the plug block to be inserted.
[0012] As a preferred technical solution of this application, a second spring is fixedly connected to the inner wall of the plug block, and the end of the second spring away from the plug block is fixedly connected to the top of the lower chord.
[0013] 1. This utility model, through the setting of a lower chord, vertical support rod, upper chord, web diagonal rod, adjustable bolt, bolt sleeve, web diagonal brace, movable hinge, and movable fastener, allows for flexible adjustment of the web diagonal rod's inclination angle by adjusting the cooperation of the adjustable bolt and bolt sleeve when the angle needs to be adjusted. This adapts to the angle requirements of different cast-in-place box girder webs, making the entire support system more closely aligned with actual construction requirements. This design not only reduces the need to customize multiple models of supports due to angle mismatch but also significantly reduces material waste, improves construction efficiency, and ensures project quality and progress.
[0014] 2. This utility model, through the setting of the connecting rod and the first spring, allows for flexible adjustment of the height of structures such as the lower chord when adjustment is required. Specifically, when the plug-in block disengages from the corresponding insertion hole, the lower chord loses all restrictions, allowing it to move upward using the elastic force of the connecting rod and the first spring. When the lower chord and other structures rise to a suitable height, one hand holds the lower chord while the other releases the plug-in block, allowing the plug-in block to engage with the corresponding insertion hole using the elastic force of the second spring, thus fixing the current position of the lower chord and ensuring the safety and accuracy of the construction process.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] This utility model provides an adjustable flange plate integral support, such as Figure 1-5As shown, the integral support of the flange plate includes a lower chord 1, a vertical support rod 2 fixedly connected to the top of the lower chord 1, an upper chord 3 fixedly connected to the top of the vertical support rod 2, a web plate diagonal rod 4 rotatably connected to one side inside the lower chord 1, adjustable bolts 5 are provided at the connection between the web plate diagonal rod 4 and the upper chord 3, and bolt sleeves 6 are threadedly connected to the outer surface of the adjustable bolts 5. A web plate diagonal brace 7 is provided on the outer wall of the lower chord 1, a movable hinge 8 is hinged to the top of the web plate diagonal brace 7 and the outer wall of the web plate diagonal rod 4, and a movable fastener 9 is movably connected to the bottom of the web plate diagonal brace 7 and the outer wall of the lower chord 1. An adjustment mechanism is provided at the bottom of the lower chord 1.
[0024] Specifically, when it is necessary to adjust the angle of the web plate diagonal brace 4 to meet different angles of the web of the cast-in-place box girder, the adjustable bolt 5 and the bolt sleeve 6 are used to move the adjustable bolt 5 within the bolt sleeve 6, thereby driving the web plate diagonal brace 4 to adjust its angle around the rotational connection point with the lower chord 1. During the adjustment process, the movable hinge 8 can flexibly adapt to the relative position changes between the web plate diagonal brace 7 and the web plate diagonal brace 4, ensuring the stability of the entire structure. At the same time, the movable fastener 9 can fine-tune the position of the web plate diagonal brace 7 according to actual needs to further enhance the overall adaptability of the support and fix the web plate diagonal brace 4 at the required angle, ensuring the reliability and safety of the support during construction.
[0025] The adjustment mechanism includes a contact base 10 located below the lower chord 1, and a support leg 11 is fixedly connected to the bottom of the contact base 10.
[0026] A connecting rod 12 is slidably connected inside the contact base 10, and one end of the connecting rod 12 near the contact base 10 is fixedly connected to the bottom of the contact base 10.
[0027] The top of the contact base 10 is fixedly connected to the outer ring of the connecting rod 12 with a first spring 13. The end of the first spring 13 away from the contact base 10 is fixedly connected to the bottom of the lower chord rod 1.
[0028] The top of the lower chord 1 is slidably connected to a plug block 14, and the outer wall of the contact base 10 is provided with multiple insertion holes 16 for the plug block 14 to be inserted.
[0029] A second spring 15 is fixedly connected to the inner wall of the plug block 14, and the end of the second spring 15 away from the plug block 14 is fixedly connected to the top of the lower chord 1.
[0030] Specifically, when the height of structures such as the lower chord 1, upper chord 3, and web plate diagonal brace 4 needs to be adjusted, the operator can first pull the plug block 14 to disengage it from the plug hole 16 on the contact base 10, thereby releasing the restriction on the lower chord 1. At this time, the first spring 13 will push the lower chord 1 upward due to its elastic force until the desired height is reached. During the adjustment process, the contact base 10 remains stable through the support leg 11, and the sliding design of the connecting rod 12 inside the contact base 10 ensures the flexibility and stability of the entire structure. After the height adjustment is completed, the plug block 14 is released, and the elastic force of the second spring 15 will push it back in. The lower chord 1 is fixed in position by inserting it into the corresponding hole 16 on the contact base 10. This adjustment method is not only easy to operate, but also effectively ensures the stability and safety of the overall bracket during use. The connecting rod 12 provides a guide for the movement of the lower chord 1, preventing instability caused by the lower chord 1 relying solely on the support of the first spring 13. At the same time, the design of the connecting rod 12 also enhances the coordination of the overall structure, ensuring that the lower chord 1 remains horizontal during movement. This guiding mechanism effectively avoids positional deviation caused by external interference, further improving the accuracy and reliability of the lower chord 1 and other structures during height adjustment.
[0031] Working principle:
[0032] When the angle of the web diagonal brace needs to be adjusted according to different angles of the web of the box girder, the inclination angle of the web diagonal brace can be flexibly changed by adjusting the fit between the adjustable bolts and the bolt sleeve to adapt to different construction requirements. During the adjustment process, the movable hinged support can provide flexible rotational support to ensure that the web diagonal brace remains stable when the angle changes. At the same time, the design of the movable fastener further enhances the reliability of the structure, so that the web diagonal brace can be firmly fixed after the set angle, avoiding displacement due to external forces. This design not only improves the applicability of the support, but also significantly improves construction efficiency and safety.
[0033] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
