Supporting device for construction of steel-concrete composite beam

Abstract

This application relates to the field of steel-concrete composite beam construction technology, and discloses a support device for steel-concrete composite beam construction, including a first C-shaped plate, a second C-shaped plate, a first hydraulic cylinder, a first clamping block, a second clamping block, a first guide rail slider pair, insert plates, baffles, tension springs, and support components. In use, extending the moving end of the first hydraulic cylinder causes the first clamping block to gradually approach the second clamping block, simultaneously moving the baffles on both sides. At this time, the inclined surfaces on both sides gradually push the insert plates away from each other until they are inserted into the first and second through holes on both sides, respectively, thus limiting the movement of the first and second C-shaped plates. Retracting the moving end of the hydraulic cylinder causes the first clamping block to gradually move away from the second clamping block, simultaneously resetting the baffles on both sides. At this time, under the tension of the tension spring, the insert plates on both sides approach each other until they are removed from the first and second through holes on both sides, respectively, allowing the first and second C-shaped plates to be disassembled.

[0002] A related technology (publication number: CN219386017U) discloses a construction support device for a steel-concrete composite beam, including a first clamp and a second clamp. The first clamp and the second clamp are detachably connected to the top of the bridge pier column via bolts. A first support steel section is connected to the end of the first clamp away from the second clamp, and a movable and adjustable first adjustment structure is connected to the top of the first support steel section. A second support steel section is connected to the end of the second clamp away from the first clamp, and a movable and adjustable second adjustment structure is connected to the top of the second support steel section. The first and second adjustment structures are used to support and place the steel-concrete composite beam and to adjust the position of the steel-concrete composite beam.

[0003] In the process of implementing the technical solution disclosed herein, at least the following problems were found in the related technologies:

[0004] The steel-concrete composite beam construction support device is fixed to the bridge pier column using a first and second clamp. Then, a first and second adjusting structure are used to adjust the position of the steel-concrete composite beam placed on it to facilitate subsequent construction. However, bolts and nuts are required when the first and second clamps tighten around the bridge pier column. Furthermore, these bolts and nuts need to be removed after construction is completed. Therefore, the operation is relatively cumbersome.

Utility Model Content

[0006] To provide a basic understanding of some aspects of the disclosed technical solutions, a brief summary is given below. This summary is not a general commentary, nor is it intended to identify key / important components or describe the scope of protection of these technical solutions, but rather serves as a prelude to the detailed explanations that follow.

[0009] Optionally, the first C-shaped plate further includes: sliding grooves, respectively located on opposite sides of opposite side walls of the first C-shaped plate, and opposite side walls of the second C-shaped plate are respectively inserted into the sliding grooves on both sides.

[0010] Optionally, the support further includes: a second hydraulic cylinder, which is installed on the opposite sides of the opposite side walls of the second C-shaped plate along the height direction of the rectangular frame; a support plate, which is installed on the moving ends of the second hydraulic cylinders on both sides; a third hydraulic cylinder, which is installed on the top surface of the support plate on both sides along the width direction of the rectangular frame; and a support block, which is installed on the moving ends of the third hydraulic cylinders on both sides.

[0011] Optionally, it further includes: a second guide rail slider pair, which is installed between the second C-shaped plate and the two side support plates along the height direction of the rectangular frame.

[0012] Optionally, it also includes: a third guide rail slider pair, which is installed between the support blocks on both sides and the support plates on both sides along the width direction of the rectangular frame.

[0013] Optionally, it also includes: a first support, which is respectively installed between the second hydraulic cylinder and the second C-shaped plate on both sides.

[0014] Optionally, it also includes: a second support, which is respectively installed between the third hydraulic cylinders on both sides and the support plates on both sides.

[0015] Optionally, it also includes: cam bearings, respectively mounted on the insert plates on both sides and respectively abutting against the inclined surfaces on both sides.

[0016] Optionally, it further includes: a third support, installed on the outer wall of the first C-shaped plate, and located between the baffles on both sides and the first hydraulic cylinder; and a fourth guide rail slider pair, installed along the length of the rectangular frame between the third support on both sides and the baffles on both sides.

[0017] The technical solution disclosed herein provides a support device for the construction of steel-concrete composite beams, which can achieve the following technical effects:

[0018] This disclosure provides a support device for the construction of steel-concrete composite beams, comprising a first C-shaped plate, a second C-shaped plate, a first hydraulic cylinder, a first clamping block, a second clamping block, a first guide rail slider pair, insert plates, baffles, tension springs, and support components. The first C-shaped plate includes first through holes located on its opposite side walls. The first C-shaped plate supports related components of the installation device, and the two first through holes allow the insert plates to pass through. The second C-shaped plate includes second through holes located on its opposite side walls. The second C-shaped plate also supports related components of the installation device, and the two second through holes also allow the insert plates to pass through. After the second C-shaped plate and the first C-shaped plate enclose a rectangular frame, the two second through holes are opposite to the two first through holes, allowing the insert plates to pass through both the two first and two second through holes simultaneously, thus providing a limiting function. The first hydraulic cylinder is installed along the length of the rectangular frame on the first C-shaped plate, located between the opposite side walls of the first C-shaped plate, and provides driving force to achieve linear movement. The first clamping block is installed on the moving end of the first hydraulic cylinder and located inside the first C-shaped plate. Driven by the first hydraulic cylinder, it moves to abut against one side of the pier column. The second clamping block is installed on the inner wall of the second C-shaped plate, opposite to the first clamping block, and abuts against the other side of the pier column. A first guide rail slider pair is installed along the width of the rectangular frame on the inner wall of the first C-shaped plate and located on both sides of the first hydraulic cylinder. Both first guide rail slider pairs together provide guidance and support. Insert plates are respectively installed on the moving ends of the two first guide rail slider pairs and can slide along the width of the rectangular frame under the guidance and support of the two first guide rail slider pairs. Baffles are connected to the first clamping block and are located between the two insert plates and the first hydraulic cylinder, both passing through the first C-shaped plate. The opposite sides of both baffles include inclined surfaces, which are used to push the two insert plates to move. A tension spring is installed between the two insert plates to provide tension, causing the two insert plates to tend to move towards each other. The support members are respectively installed on the opposite sides of the two side walls of the second C-shaped plate, and are used to support the steel-concrete composite beam and drive the steel-concrete composite beam to move along the height and width of the rectangular frame.

[0019] This disclosure provides a support device for constructing a steel-concrete composite beam. After a first and second C-shaped plate surround a bridge pier column to form a rectangular frame, the moving end of a first hydraulic cylinder extends, causing a first clamping block to gradually approach the second clamping block. Simultaneously, this moves the side baffles. At this point, the inclined surfaces on both sides gradually push the side inserts away from each other until they are inserted into the first and second through holes on both sides, respectively, thus limiting the position of the first and second C-shaped plates. Finally, the first and second clamping blocks together clamp the bridge pier column. The steel-concrete composite beam can then be placed on the support and moved along the height and width of the rectangular frame under the action of the support to adjust its position for subsequent construction. After construction is completed, the moving end of the hydraulic cylinder retracts, causing the first clamping block to gradually move away from the second clamping block to release the bridge pier column. Simultaneously, the side baffles return to their original positions. At this point, under the tension of the spring, the two insert plates move closer together until they are removed from the first and second through holes on both sides, respectively, allowing the first and second C-shaped plates to be disassembled. Therefore, it offers advantages in both installation and disassembly. Furthermore, due to the large contact area between the insert plates and the first and second C-shaped plates, it can withstand greater forces. Simultaneously, the design of using the first and second C-shaped plates to support the relevant components of the installation device balances the weight of the two parts of the device, facilitating the enclosure of the bridge pier and the formation of a rectangular frame.

[0037] Combination Figures 1 to 5As shown, this embodiment of the present disclosure provides a support device for the construction of a steel-concrete composite beam, including a first C-shaped plate 1, a second C-shaped plate 2, a first hydraulic cylinder 3, a first clamping block 4, a second clamping block 5, a first guide rail slider pair 6, insert plates 7, baffles 8, tension springs 9, and support members. The first C-shaped plate 1 includes first through holes located on its opposite side walls. The first C-shaped plate 1 is used to support related components of the installation device, and the two side through holes are respectively used for the insertion plates 7 to pass through. The second C-shaped plate 2 includes second through holes located on its opposite side walls. The second C-shaped plate 2 is also used to support related components of the installation device, and the two side second through holes are also respectively used for the insertion plates 7 to pass through. After the second C-shaped plate 2 and the first C-shaped plate 1 enclose a rectangular frame, the two side second through holes are respectively opposite to the two side first through holes, so that the two side insert plates 7 can simultaneously pass through the two side first through holes and the two side second through holes, thereby playing a limiting role. The first hydraulic cylinder 3 is installed along the length of the rectangular frame on the first C-shaped plate 1, located between the opposite side walls of the first C-shaped plate 1, to provide driving force for linear movement. The first clamping block 4 is installed at the moving end of the first hydraulic cylinder 3, located inside the first C-shaped plate 1, and moves under the drive of the first hydraulic cylinder 3 to abut against one side of the pier column. The second clamping block 5 is installed on the inner wall of the second C-shaped plate 2, opposite to the first clamping block 4, and abuts against the other side of the pier column. The first guide rail slider pair 6 is installed along the width of the rectangular frame on the inner wall of the first C-shaped plate 1, located on both sides of the first hydraulic cylinder 3; the two first guide rail slider pairs 6 together provide guidance and support. Insert plates 7 are respectively installed at the moving ends of the two first guide rail slider pairs 6, and can slide along the width of the rectangular frame under the guidance and support of the two first guide rail slider pairs 6. Baffles 8 are connected to the first clamping block 4 and are located between the two side inserts 7 and the first hydraulic cylinder 3, respectively, and both pass through the first C-shaped plate 1. The opposite sides of both side baffles 8 include inclined surfaces, which are used to push the two side inserts 7 to move. Tension springs 9 are installed between the two side inserts 7 to provide tension, so that the two side inserts 7 tend to move towards each other. Support members are installed on the opposite side walls of the second C-shaped plate 2, respectively, to support the steel-concrete composite beam and drive the steel-concrete composite beam to move along the height and width directions of the rectangular frame.

[0038] This embodiment of the invention provides a support device for the construction of a steel-concrete composite beam. After a first C-shaped plate 1 and a second C-shaped plate 2 surround a bridge pier column and form a rectangular frame, the moving end of a first hydraulic cylinder 3 extends, causing a first clamping block 4 to gradually approach a second clamping block 5. Simultaneously, this moves the side baffles 8. At this point, the inclined surfaces on both sides gradually push the side inserts 7 away from each other until they are inserted into the first and second through holes on both sides, respectively, thus limiting the position of the first C-shaped plate 1 and the second C-shaped plate 2. Finally, the first clamping block 4 and the second clamping block 5 together clamp the bridge pier column. The steel-concrete composite beam can then be placed on the support and moved along the height and width of the rectangular frame under the action of the support to adjust its position for subsequent construction. After construction is completed, the moving end of the hydraulic cylinder retracts, causing the first clamping block 4 to gradually move away from the second clamping block 5 to release the bridge pier column. Simultaneously, the side baffles 8 return to their original position. At this point, under the tension of the tension spring 9, the two insert plates 7 move closer together until they are removed from the first and second through holes on both sides, respectively, allowing the first C-shaped plate 1 and the second C-shaped plate 2 to be disassembled. Therefore, it has advantages in both installation and disassembly directions. Furthermore, because the contact area between the insert plate 7 and the first C-shaped plate 1 and the second C-shaped plate 2 is large, it can withstand greater forces. Simultaneously, the design of using the first C-shaped plate 1 and the second C-shaped plate 2 to support the relevant components of the installation device balances the weight of the two parts of the device, facilitating the enclosure of the bridge pier column and the formation of a rectangular frame.

[0039] Optionally, combined Figure 4 and Figure 5 As shown, the first C-shaped plate 1 also includes sliding grooves. The sliding grooves are located on opposite sides of the opposite side walls of the first C-shaped plate 1, and the opposite side walls of the second C-shaped plate 2 are respectively inserted into the sliding grooves on both sides.

[0040] In this embodiment of the present disclosure, the side grooves are used to limit the insertion of the second C-shaped plate 2 into the first C-shaped plate 1.

[0041] Optionally, combined Figure 1 and Figure 4 As shown, the support structure also includes a second hydraulic cylinder 10, a support plate 11, a third hydraulic cylinder 12, and a support block 13. The second hydraulic cylinders 10 are mounted on opposite sides of the opposite side walls of the second U-shaped plate 2 along the height direction of the rectangular frame, and are used to provide driving force to achieve linear movement. The support plates 11 are mounted on the moving ends of the second hydraulic cylinders 10 on both sides, and move along the height direction of the rectangular frame under the drive of the second hydraulic cylinders 10. The third hydraulic cylinders 12 are mounted on the top surfaces of the support plates 11 on both sides along the width direction of the rectangular frame, and are used to provide driving force to achieve linear movement. The support blocks 13 are mounted on the moving ends of the third hydraulic cylinders 12 on both sides, and move along the width direction of the rectangular frame under the drive of the third hydraulic cylinders 12.

[0042] In this embodiment, by simultaneously controlling the moving ends of the two second hydraulic cylinders 10 to move in the same direction, the two support plates 11 can rise or fall simultaneously, ultimately driving the two support blocks 13 to rise or fall simultaneously. By simultaneously controlling the moving ends of the two second hydraulic cylinders 10 to move in the same direction, the two second support blocks 13 can move back and forth simultaneously. Therefore, by coordinating the work of the two first hydraulic cylinders 3 and the two second hydraulic cylinders 10, the function of moving the steel-concrete composite beam along the height and width directions of the rectangular frame can be achieved.

[0043] Optionally, combined Figure 1 , Figure 3 and Figure 4 As shown, it also includes a second guide rail slider pair 14. The second guide rail slider pair 14 is installed between the second C-shaped plate 2 and the two side support plates 11 along the height direction of the rectangular frame.

[0044] In this embodiment, the two second guide rail slider pairs 14 are used to serve as guide supports to improve the stability of the two support plates 11 when they move and reduce the radial force on the moving ends of the two second hydraulic cylinders 10.

[0045] Optionally, combined Figure 1 , Figure 3 and Figure 4 As shown, it also includes a third guide rail slider assembly 15. The third guide rail slider assembly 15 is installed between the two side support blocks 13 and the two side support plates 11 along the width direction of the rectangular frame.

[0046] In this embodiment, the two third guide rail slider pairs 15 are used to serve as guide supports to improve the stability of the two support plates 11 when they move and reduce the radial force on the moving ends of the two third hydraulic cylinders 12.

[0047] Optionally, combined Figure 1 , Figure 3 and Figure 4 As shown, it also includes a first support 16. The first support 16 is respectively installed between the second hydraulic cylinders 10 on both sides and the second C-shaped plate 2.

[0048] In this embodiment of the present disclosure, the first support 16 is respectively installed on the opposite sides of the opposite side walls of the first C-shaped plate 1, and is used to support the installation of the second hydraulic cylinders 10 on both sides, so as to facilitate the installation or removal of the second hydraulic cylinders 10 on both sides.

[0049] Optionally, combined Figure 4 As shown, it also includes a second support 17. The second support 17 is respectively installed between the third hydraulic cylinders 12 on both sides and the support plates 11 on both sides.

[0050] In this embodiment, the second support 17 is installed on the two side support plates 11 respectively, and is used to support the installation of the two side third hydraulic cylinders 12, so as to facilitate the installation or disassembly of the two side third hydraulic cylinders 12.

[0051] Optionally, combined Figure 1 and Figure 2 As shown, it also includes cam bearings 18. The cam bearings 18 are respectively mounted on the two side plates 7 and abut against the two side inclined surfaces.

[0052] In this embodiment, both cam bearings 18 are used to reduce friction so that the side inserts 7 can move along with the side baffles 8.

[0053] Optionally, combined Figure 1 and Figure 2 As shown, it also includes a third support 19 and a fourth guide rail slider pair 20. The third support 19 is installed on the outer wall of the first C-shaped plate 1 and is located between the two side baffles 8 and the first hydraulic cylinder 3. The fourth guide rail slider pair 20 is installed along the length of the rectangular frame between the two third supports 19 and the two side baffles 8.

[0054] In this embodiment, the third supports 19 on both sides are used to support the installation of the fourth guide rail slider pairs 20 on both sides. The fourth guide rail slider pairs 20 on both sides serve as guide supports to improve the stability of the side baffles 8 when they move and reduce the radial force on the moving end of the first hydraulic cylinder 3.
