Description

Technical Field

[0001] This utility model relates to the field of steel pipe arch rib installation technology, and in particular to a clamp-type support platform for steel pipe arch rib installation. Background Technology

[0002] In highway bridge engineering, especially in the construction of steel-concrete composite arch bridges, choosing a suitable method for lifting and installing steel arch ribs is a key challenge that needs to be addressed in many arch bridge construction projects. Limited lifting space, complex lifting conditions, difficulties in cost control, cumbersome installation procedures, and other factors contribute to the difficulty in lifting steel arch ribs, posing a significant challenge for arch bridge builders. A suitable arch rib clamping platform can increase the efficiency and accuracy of arch rib installation.

[0003] Currently, in the field of arch bridge construction, the main methods for adjusting and fixing the arch ribs include using wedge blocks or hanging guy ropes on the arch ribs to adjust and fix the arch ribs linearly. These methods can effectively complete the installation of the arch ribs during the installation process. However, these methods take a lot of time to adjust the linearity of the arch ribs and the fixing measures are cumbersome. At the same time, the welding of the wedge blocks to the arch ribs during fixing can damage the arch ribs themselves, resulting in a long time for later repairs. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology, which uses wedge blocks to linearly adjust and fix the arch ribs, resulting in long adjustment time and complicated fixing measures. This invention provides a steel pipe arch rib mounting clamp-type support platform.

[0005] This utility model provides a steel pipe arch rib mounting clamp-type support platform, including...

[0006] The clamp top cover includes a first arc-shaped bonding plate with its inner arc facing downwards, and the first arc-shaped bonding plate can bond to the upper surface of the steel pipe arch rib.

[0007] The clamp base is located below the clamp top cover. The clamp base includes a second arc-shaped bonding plate with its inner arc surface facing upward. The second arc-shaped bonding plate can bond to the lower surface of the steel pipe arch rib. The first arc-shaped bonding plate and the second arc-shaped bonding plate are detachably connected.

[0008] A clamp base beam is connected to the bottom of the clamp base and is used to support the clamp base.

It is detachably connected by a first arc-shaped fitting plate and a second arc-shaped fitting plate to achieve installation and clamp fixation. Supported by the clamp bottom beam, it can adapt to the linearity of the steel pipe arch rib, thereby achieving linear adjustment during installation. It takes less time, and the detachable connection makes installation and fixation simple. It does not require welding to the steel pipe arch rib, avoiding damage to the steel pipe arch rib during later disassembly, and thus eliminating the need for subsequent repair of the outer surface quality of the steel pipe arch rib.

[0012] Preferably, the clamp top cover further includes an arc-shaped stiffening plate, which is transversely arranged on the outer side of the outer arc surface of the first arc-shaped bonding plate along the steel pipe arch rib.

[0013] The curved stiffening plate can provide lateral reinforcement to the first curved bonding plate, thereby improving the fixing strength.

[0014] Preferably, the clamp top cover further includes a radial stiffening plate, which is connected at the angle between the top of the arc-shaped stiffening plate and the first arc-shaped bonding plate, thereby improving the connection strength between the arc-shaped stiffening plate and the first arc-shaped bonding plate and forming axial reinforcement of the steel pipe arch rib.

[0015] Preferably, the clamp base further includes a base plate and a vertical support plate. The base plate is connected to the top surface of the clamp bottom beam and is located below the second arc-shaped bonding plate. The vertical support plate vertically connects the base plate and the outer arc surface of the second arc-shaped bonding plate.

[0016] The clamp base uses a base plate and a vertical support plate to support the second arc-shaped bonding plate. While ensuring the support strength, the structure is simple, easy to process, and can reduce weight, making it more convenient for installation and construction.

[0017] Preferably, the clamp top cover further includes a first end plate, which is horizontally connected to the included angle between the ends of the arc-shaped stiffening plate and the first arc-shaped bonding plate, and the first end plate is provided with vertical upper bolt holes;

[0018] The clamp base also includes a second end plate, which is horizontally connected to the included angle between the ends of the vertical support plate and the second arc-shaped bonding plate. The second end plate is provided with a lower bolt hole corresponding to the upper bolt hole.

[0019] The first end plate and the second end plate are connected by high-strength bolts passing through the upper bolt hole and the corresponding lower bolt hole.

[0020] By horizontally connecting the first end plate at the angle between the ends of the arc-shaped stiffening plate and the first arc-shaped bonding plate, and horizontally connecting the second end plate at the angle between the ends of the vertical support plate and the second arc-shaped bonding plate, the first end plate and the second end plate are connected by high-strength bolts passing through the upper bolt holes and the corresponding lower bolt holes, thereby achieving a detachable connection between the first arc-shaped bonding plate and the second arc-shaped bonding plate, fixing the steel pipe arch rib, ensuring the linearity of the steel pipe arch rib, this connection method has high strength and is easy to assemble and disassemble.

[0021] Preferably, the clamp base further includes a vertical stiffening plate, and the second arc-shaped bonding plate, the vertical support plate and the base plate are connected by the vertical stiffening plate, which can achieve axial reinforcement of the steel pipe arch rib.

[0022] Preferably, the second end plate, the vertical support plate, and the base plate are connected by the vertical stiffening plate, which can strengthen the second end plate and improve the connection stability between the first end plate and the second end plate.

[0023] Preferably, the clamp bottom beam is arranged transversely along the steel pipe arch rib to facilitate connection with the base plate.

[0024] Preferably, the bottom beam of the clamp is an I-beam steel beam, which has high strength and good support performance.

The first arc-shaped fitting plate and the second arc-shaped fitting plate are detachably connected to achieve installation and clamp fixation. With the support of the clamp bottom beam, it can adapt to the linearity of the steel pipe arch rib, thereby realizing linear adjustment during the installation of the steel pipe arch rib. It takes less time, and the installation and fixation can be carried out by detachable connection.

[0038] Example 1

[0039] like Figures 1-2 As shown, a steel pipe arch rib mounting clamp type support platform includes a clamp top cover 21, a clamp base 22, and a clamp bottom beam 23.

[0040] like Figure 3 As shown, the clamp top cover 21 includes a first arc-shaped bonding plate 210, the inner arc surface of the first arc-shaped bonding plate 210 is downward, and the first arc-shaped bonding plate 210 can bond to the upper surface of the steel pipe arch rib 1.

[0041] like Figure 3As shown, the clamp base 22 is located below the clamp top cover 21. The clamp base 22 includes a second arc-shaped bonding plate 220, with the inner arc surface of the second arc-shaped bonding plate 220 facing upward. The second arc-shaped bonding plate 220 can fit the lower surface of the steel pipe arch rib 1. The first arc-shaped bonding plate 210 and the second arc-shaped bonding plate 220 are detachably connected.

[0042] The clamp base beam 23 is connected to the bottom of the clamp base 22, and the clamp base beam 23 is used to support the clamp base 22.

[0043] like Figure 1 As shown, the clamp top cover 21 also includes an arc-shaped stiffening plate 211, a radial stiffening plate 212, and a first end plate 214.

[0044] The arc-shaped stiffening plate 211 is arranged laterally along the outer side of the outer arc surface of the first arc-shaped bonding plate 210 along the steel pipe arch rib 1. The arc-shaped stiffening plate 211 can laterally strengthen the first arc-shaped bonding plate 210 and improve its fixing strength.

[0045] The radial stiffening plate 212 is connected at the angle between the top of the arc stiffening plate 211 and the first arc bonding plate 210, which can improve the connection strength between the arc stiffening plate 211 and the first arc bonding plate 210, and can form axial reinforcement of the steel pipe arch rib 1.

[0046] The first end plate 214 is horizontally connected to the end angle of the arc-shaped stiffening plate 211 and the first arc-shaped bonding plate 210, and the first end plate 214 is provided with a vertical upper bolt hole 25.

[0047] The clamp base 22 also includes a base plate 221, a vertical stiffening plate 222, a vertical support plate 223, and a second end plate 224.

[0048] The base plate 221 is connected to the top surface of the clamping bottom beam 23, which is arranged laterally along the steel pipe arch rib 1 for easy connection with the base plate 221. The clamping bottom beam 23 is an I-beam steel beam with high strength and good support performance. The base plate 221 is located below the second arc-shaped bonding plate 220, and the vertical support plate 223 vertically connects the base plate 221 and the outer arc surface of the second arc-shaped bonding plate 220. The clamping base 22 uses the base plate 221 and the vertical support plate 223 to support the second arc-shaped bonding plate 220. While ensuring support strength, the structure is simple, easy to process, and can reduce weight, making it more convenient for installation and construction. The second arc-shaped bonding plate 220, the vertical support plate 223, and the base plate 221 are connected by the vertical stiffening plate 222, which can achieve axial reinforcement of the steel pipe arch rib.

[0049] The second end plate 224 is horizontally connected to the included angle between the ends of the vertical support plate 223 and the second arc-shaped bonding plate 220. The second end plate 224 is provided with a lower bolt hole 26 corresponding to the upper bolt hole 25. The first end plate 214 and the second end plate 224 are connected by a high-strength bolt 24 passing through the upper bolt hole 25 and the corresponding lower bolt hole 26. By horizontally connecting the first end plate 214 at the included angle between the ends of the arc-shaped stiffening plate 211 and the first arc-shaped bonding plate 210, and horizontally connecting the second end plate 224 at the included angle between the ends of the vertical support plate 223 and the second arc-shaped bonding plate 220, the first end plate 214 and the second end plate 224 are connected by a high-strength bolt 24 passing through the upper bolt hole 25 and the corresponding lower bolt hole 26, thereby realizing a detachable connection between the first arc-shaped bonding plate 210 and the second arc-shaped bonding plate 220, fixing the steel pipe arch rib, ensuring the linearity of the steel pipe arch rib, and this connection method has high strength and is easy to disassemble and assemble.

[0050] The second end plate 224, the vertical support plate 223 and the base plate 221 are connected by the vertical stiffening plate 222, which can strengthen the second end plate 224 and improve the connection stability between the first end plate 214 and the second end plate 224.

[0051] In a preferred embodiment, the inner arc surfaces of the first arc-shaped bonding plate 210 and the second arc-shaped bonding plate 220 can form a vertical elliptical cross-section. That is, as... Figure 1 and Figure 3 As shown, the ellipse formed by the inner arcs of the first arc-shaped bonding plate 210 and the second arc-shaped bonding plate 220 does not correspond to the cross-section of the steel pipe arch rib, but rather to the vertical cross-section of the steel pipe arch rib; as Figure 2 and Figure 4 As shown, the bottom beam 23 of the clamp is set horizontally, and the steel pipe arch rib is set inclined. The axial direction of the steel pipe arch rib is set at an angle β with the horizontal direction. Correspondingly, the left and right directions of the inner arc surfaces of the first arc-shaped bonding plate 210 and the second arc-shaped bonding plate 220 are also set at an angle β with the horizontal direction. However, the left and right sides of the first arc-shaped bonding plate 210 and the left and right sides of the second arc-shaped bonding plate 220 are vertically aligned, that is, they are not aligned radially along the steel pipe arch rib. This arrangement allows the clamp top cover 21 and the clamp base 22 to be detachably connected to form a vertical force-bearing structure with better force-bearing capacity.

[0052] In this embodiment, the clamp top cover 21 and clamp base 22 need to be processed according to the arch rib inclination angle β of the steel pipe arch rib 1 at each clamp position. The clamp base 22 and clamp top cover 21 should be able to fit tightly against the arch rib, so that the steel pipe arch rib 1 is limited by the clamp, thereby achieving the arch rib inclination angle of the steel pipe arch rib 1 as required by the design.

[0053] Using the steel pipe arch rib installation clamp-type support platform described in this embodiment, by processing the clamp-type support platform to conform to the arch rib shape, first install the clamp bottom beam 23 onto the assembly bracket of the steel pipe arch rib 1. During installation, it is necessary to adjust the clamp elevation of the clamp bottom beam 23 according to the elevation position of the steel pipe arch rib 1 by measurement and layout (i.e., Figure 3 (Height in the Z direction), then the clamp mileage of the clamp base 22 (i.e. Figure 4 The position in the Y direction) and the clamp misalignment (i.e. Figure 3 After the position in the X direction is measured and laid out, it is welded to the bottom beam 23 of the clamp. After the steel pipe arch rib 1 is hoisted to the clamp base 22, the clamp top cover 21 is put on. The clamp top cover 21 is adjusted so that the upper bolt hole 25 and the lower bolt hole 26 are aligned. After alignment, the high-strength bolt 24 is passed through the upper bolt hole 25 and the lower bolt hole 26 and then tightened. This completes the installation and fixing of the arch rib. The spatial position of the steel pipe arch rib is restricted by the clamp to achieve the arch rib line shape required by the design. After the clamp top cover is fixed with high-strength bolts, it can also meet the requirements for fixing the steel pipe arch rib. Thus, the purpose of quickly installing and adjusting the position of the arch rib and quickly fixing the arch rib is achieved. At the same time, the clamp fixing does not cause damage to the steel pipe arch rib due to the welding limit of the welding plate.

[0054] The steel pipe arch rib installation clamp-type support platform described in this embodiment uses the inner arc surface of the clamp top cover 21 to adhere downwards to the upper surface of the steel pipe arch rib 1, and the inner arc surface of the clamp base 22 to adhere upwards to the lower surface of the steel pipe arch rib 1. The first arc-shaped fitting plate 210 and the second arc-shaped fitting plate 220 are detachably connected to achieve installation and clamp fixation. Supported by the clamp bottom beam 23, it can adapt to the linearity of the steel pipe arch rib 1, thereby achieving linear adjustment during installation. This reduces the time required and solves the problem of cumbersome and time-consuming steel pipe arch rib position adjustment processes in most current steel pipe arch rib installations. Furthermore, the detachable connection method simplifies installation and fixation, and eliminates the need for welding to the steel pipe arch rib 1, avoiding damage to the steel pipe arch rib 1 during later disassembly. This also eliminates the need for subsequent repairs to the outer surface quality of the steel pipe arch rib 1, solving problems such as long operation time and damage to the arch rib itself due to welding limiting plates during the fixing of the arch rib after adjustment.

[0055] 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.
