Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and more specifically, to a height-adjustable cap beam reinforcement fabrication platform. Background Technology

[0002] In bridge construction, the cap beam is a crucial component connecting the piers to the superstructure, and the dimensional accuracy and overall stability of its steel reinforcement cage are paramount. Currently, during the on-site fabrication of the cap beam steel reinforcement cage, simple support frames, wooden blocks, or temporary welded supports are commonly used. These traditional support methods have significant shortcomings: their support height is fixed, making them inflexible and unable to adapt to the construction needs of cap beam steel reinforcement cages of different sizes, resulting in poor versatility. Therefore, there is an urgent need for a specialized support platform that can flexibly adjust its height. Utility Model Content

[0004] The objective of this utility model is achieved through the following technical solution: A height-adjustable cap beam reinforcement fabrication platform includes a base and at least two sets of height adjustment mechanisms spaced apart on the base. The execution end of any of the height adjustment mechanisms is provided with a support crossbar, and the support surface of any of the support crossbars is coplanar with the horizontal plane.

[0005] Furthermore, in this utility model, the middle part of any of the above-mentioned support crossbars is connected to the execution end of the corresponding height adjustment mechanism; both ends of any of the above-mentioned support crossbars are provided with telescopic rods, the end of any of the above-mentioned telescopic rods away from the support crossbars is connected to the base, and the extension and retraction direction of any of the above-mentioned telescopic rods is parallel to the vertical direction.

[0014] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0015] Example 1 Please see Figure 1 and Figure 2 This embodiment provides a technical solution: A height-adjustable rebar fabrication platform for cap beams includes a base 101 and at least two sets of height adjustment mechanisms spaced apart on the base 101. Each height adjustment mechanism has a supporting crossbar 201 mounted at its actuating end, and the supporting surface of each crossbar 201 is coplanar with the horizontal plane. In this embodiment, the base 101 consists of two parallel I-beams connected by several connecting rods. In other embodiments of this invention, the number of supporting crossbars 201 can be increased according to the length of the rebar cage. If the number of supporting crossbars 201 needs to be increased, the number of height adjustment mechanisms also increases accordingly.

[0016] In this embodiment, the middle part of any support crossbar 201 is connected to the execution end of the corresponding height adjustment mechanism. To further improve the stability of the support, a telescopic rod 301 is installed at both ends of any support crossbar 201 in this embodiment. The end of the telescopic rod 301 away from the support crossbar 201 is connected to the base 101, and the extension and retraction direction of the telescopic rod 301 is parallel to the vertical direction.

[0017] Specifically, in this embodiment, the height adjustment mechanism is a hydraulic rod 401 installed on the base 101. The central axis of the hydraulic rod 401 is parallel to the vertical direction, and the free end of the piston rod of the hydraulic rod 401 is connected to the support crossbar 201.

[0018] By controlling the extension and retraction of the hydraulic rod 401, the vertical height of the support crossbar 201 can be controlled, allowing the platform to flexibly adapt to the construction needs of steel reinforcement cages for cap beams of different sizes.

[0019] Example 2 Please see Figure 2The difference between this embodiment and Embodiment 1 is that the height adjustment mechanism in this embodiment is manually adjustable. In this embodiment, the height adjustment mechanism consists of a support tube 501 connected to the base 101 at its bottom, a threaded sleeve 502 rotatably mounted at the top of the support tube 501 (the threaded sleeve 502 is rotatably connected to the support tube 501 via a bearing), and a screw 503 threadedly connected to the threaded sleeve 502. The central axis of the screw 503 and the central axis of the threaded sleeve 502 are both collinear with the central axis of the support tube 501, and the central axis of the support tube 501 is parallel to the vertical direction. The end of the screw 503 away from the threaded sleeve 502 is rotatably connected to the support crossbar 201. To facilitate the rotation of the threaded sleeve 502, a handle (not shown in the figure) is also provided on the threaded sleeve 502 in this embodiment. Thus, when it is necessary to adjust the height of the support crossbar 201 in the vertical direction, rotating the threaded sleeve 502 will move the support crossbar 201 in the vertical direction, allowing this platform to flexibly adapt to the construction needs of different sized cap beam reinforcement cages.

[0020] After the height of the support crossbar 201 is adjusted to the correct position, in order to prevent the threaded sleeve 502 from rotating accidentally and causing displacement of the support crossbar 201 in the vertical direction, a locking screw 601 with one end abutting against the threaded sleeve 502 is also threaded onto the support tube 501 in this embodiment. One end of the locking screw 601 passes through the support tube 501 and extends into the interior of the support tube 501. When the corresponding end of the locking screw 601 abuts against the corresponding part of the threaded sleeve 502 where no bearing is installed, the threaded sleeve 502 cannot rotate around its own central axis.

[0021] Example 3 Please see Figure 3 and Figure 4 The difference between this embodiment and the above embodiments is that the height adjustment mechanism in this embodiment is manually adjusted. In this embodiment, any height adjustment mechanism consists of a vertical tube 701 mounted on the base 101, a rack 702 slidably connected to the vertical tube 701, a rotating shaft 703 rotatably mounted on the vertical tube 701, a gear 704 fixedly mounted on the rotating shaft 703, and a one-way locking mechanism mounted on the vertical tube 701. The gear 704 meshes with the rack 702. The central axis of the vertical tube 701, the central axis of the rack 702, and the sliding direction of the rack 702 are all parallel to the vertical direction. The end of the rack 702 away from the base 101 is connected to the support crossbar 201. The one-way locking mechanism allows the gear 704 to rotate forward but not backward. When the gear 704 rotates forward, it causes the rack 702 to move upward in the vertical direction.

[0022] Specifically, refer to Figure 4In this embodiment, the one-way locking mechanism includes a ratchet 801 fixedly mounted on a rotating shaft 703, a pawl 802 rotatably mounted on a vertical tube 701 at one end, and a spring 803 connected to the vertical tube 701 at one end. The free end of the spring 803 is connected to the pawl 802. The installation method and size of the spring 803 must ensure that the pawl 802 is always engaged with the ratchet 801.

[0023] When the vertical height of the support crossbar 201 needs to be adjusted, the gear 704 is rotated in its rotatable direction, causing the rack 702 to move upwards in the vertical direction, thus changing the vertical position of the support crossbar 201. Once the vertical position of the support crossbar 201 is adjusted, the rack 702 cannot move downwards in the vertical direction due to the one-way locking mechanism. If it is necessary to move the rack 702 downwards in the vertical direction, the pawl 802 can be disengaged from the ratchet 801, allowing the rack 702 to move downwards within the vertical tube 701.

It should be understood that this utility model is not limited to the forms disclosed herein and should not be construed as excluding other embodiments. It can be used in various other combinations, modifications, and environments, and can be altered within the scope of the concept described herein through the above teachings or related technologies or knowledge.
