Description

Technical Field

[0001] This utility model belongs to the field of damper technology and provides a device for adjusting the pre-reserved reinforcement in wet joints. Background Technology

[0002] With the development of construction technology, reinforced concrete structures have become the main structural form for buildings, bridges, and water conservancy projects. Because the main structural units are typically large in plan size, it is difficult to pour concrete in one go; therefore, construction joints are required in sections during construction. Taking bridges as an example, during the beam and slab erection stage, splicing reinforcement is usually reserved at the construction joints to facilitate the connection of adjacent beams and slabs.

[0003] However, in actual construction, problems such as inaccurate beam and slab placement and inadequate control of bridge deck cross slope sometimes occur, leading to misalignment of the embedded reinforcement bars in the wet joints during lap splicing. If timely adjustments to the embedded reinforcement bars are not taken, subsequent quality issues such as bridge deck cracking may arise. Therefore, it is necessary to straighten or raise the reserved reinforcement bars in the connection area before construction. However, due to the generally large quantity and high strength of the reinforcement bars, adjustment is challenging, thus affecting the quality and schedule of subsequent processes. To solve this problem, this invention proposes a wet joint embedded reinforcement bar adjustment device. This device can effectively and quickly adjust the embedded reinforcement bars, thereby ensuring construction quality, reducing the incidence of subsequent problems, and improving construction efficiency. Utility Model Content

[0004] In view of this, the purpose of this utility model is to provide a wet joint pre-reserved reinforcement adjustment device to solve the current problem of inaccurate position of wet joint pre-reserved reinforcement, while improving construction efficiency, saving costs, and making wet joint construction more standardized and regulated.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] This utility model provides a wet joint pre-reserved reinforcement adjustment device, including a traveling wheel, a telescopic rod, a support leg, and a pry bar. The lower end of the telescopic rod is connected to the traveling wheel via a pivot, and the upper end of the telescopic rod is equipped with a pry bar. The support leg and the pry bar are hinged to the telescopic rod near the pivot and on the opposite side of the traveling wheel. The pry bar has a W-shaped hook at its front end facing away from the telescopic rod, and a pin is provided on the pry bar. The telescopic rod has a pin hole that matches the pin. Through the reasonable configuration of these components, this wet joint pre-reserved reinforcement adjustment device can provide a flexible adjustment scheme on the construction site, achieving precise control of the wet joint pre-reserved reinforcement, ensuring its accurate position, thereby improving construction quality and reducing the incidence of subsequent problems. The design of this device also helps to improve construction efficiency, reduce labor costs, and make wet joint construction more standardized and regulated.

[0007] Optionally, the telescopic rod is equipped with a sleeve, at least one end of which is provided with a detachably connected auxiliary grip. The sleeve serves as a mounting base for the auxiliary grip, allowing for its removal and installation, and facilitating adjustment as needed.

[0008] Optionally, the support legs are equipped with U-shaped plates at their bottom ends facing away from the telescopic rod. The U-shaped plate design increases the ground contact area of ​​the support legs, thus providing better support. This helps to effectively distribute the applied force during adjustment, reducing the risk of excessive local stress and improving the overall structural stability.

[0009] The beneficial effects of this utility model are: the wet joint pre-reserved reinforcement adjustment device of this utility model has a simple structure, can be obtained by self-processing, and is easy to operate and reusable, effectively solving the problem of uneven height of wet joints between two adjacent beams.

[0010] Other advantages, objectives, and features of this invention will be set forth in part in the description which follows, and in part will be apparent to those skilled in the art from the following examination and study, or may be learned from practice of this invention. The objectives and other advantages of this invention can be realized and obtained through the following description. Attached Figure Description

[0015] The present invention will be further described below with reference to specific embodiments. The accompanying drawings are for illustrative purposes only, representing schematic diagrams rather than actual physical objects, and should not be construed as limiting the scope of this patent. To better illustrate the embodiments of the present invention, some components in the drawings may be omitted, enlarged, or reduced, and do not represent the actual dimensions of the product. It is understandable to those skilled in the art that some well-known structures and their descriptions may be omitted in the drawings.

[0016] like Figure 1-2 As shown, the wet joint pre-reserved reinforcement adjustment device mentioned in this utility model includes a traveling wheel 1, a telescopic rod 2, a support leg 6, and a pry bar 8. The telescopic rod 2 serves as the main supporting component of the device, with its lower end connected to the traveling wheel 1 via a rotating shaft 12. The length of the telescopic rod 2 is adjustable to accommodate construction needs at different heights. The traveling wheel 1 is located at the bottom of the device, providing support and mobility for flexible movement on the construction site. A pry bar 3 is provided at the upper end of the telescopic rod 2, providing a downward pressure point so that the applied force can be effectively transmitted to the wet joint pre-reserved reinforcement. The telescopic rod 2 has a pry bar 8 near the rotating shaft 12. The device is hinged to a support leg 6 and a pry bar 8 on the opposite side of the traveling wheel 1. The support leg 6 provides a fulcrum for the device, ensuring its stability during force application. The pry bar 8 has a W-shaped hook 9 at its front end away from the telescopic rod 2. The hook 9 is sized to meet the spacing of the reserved steel bars of two adjacent wet joints, allowing simultaneous adjustment of the reserved steel bars of two wet joints. The pry bar 8 is equipped with a pin 10 to lock the position of the pry bar 8 relative to the telescopic rod 2, ensuring that the pry bar 8 will not move during adjustment. The telescopic rod 2 is equipped with a pin hole 11 that matches the pin 10, allowing the operator to quickly fix or loosen the pry bar by inserting and pulling out the pin 10.

[0017] In this embodiment, the telescopic rod 2 is provided with a plug 5, and at least one end of the plug 5 is provided with an auxiliary grip 4 that is detachably connected. The auxiliary grip 4 is provided on the telescopic rod 2 to cooperate with the pry bar 3 on the telescopic rod 2, and to be operated by one worker with both hands or by two people. The auxiliary grip 4 is installed on the left and right sides of the telescopic rod 2 using a pin 10. This means that the operator can flexibly switch the grip method of the left and right hands according to their own habits and needs, thereby improving the comfort and efficiency of operation. In addition, the auxiliary grip 4 can also serve to support the pry bar 8 after the pin 10 is pulled out relative to the pin hole 11 and the pry bar 8 is rotated upward.

[0018] In this embodiment, the support leg 6 is provided with a U-shaped plate 7 at the bottom end away from the telescopic rod 2. The U-shaped plate 7 not only increases the force-bearing area of ​​the support leg 6 to better serve as a fulcrum, but also has a groove in the middle so that it can be locked onto the pry bar 8 placed on the auxiliary handle 4 after rotating with the pry bar 8, thus achieving a folding effect and facilitating the movement of the travel wheel 1.

[0019] Before using this device to adjust the pre-reserved reinforcement bars in wet joints, construction personnel need to first determine the specific location and height of the bars to be adjusted. According to design requirements, the adjustment device should be placed in the corresponding construction area for subsequent operations. This movement can be achieved via the travel wheels, allowing construction personnel to easily move the device to the target position. Once the device reaches the designated position, the support leg is rotated and contacts the ground. The U-shaped plate increases the support area, providing stable support. When the support leg is on the ground, the travel wheel is lifted off the ground and is not under stress during the prying process. At this time, the support leg ensures that the device will not tip over or slip when force is applied. Counterweights or other heavy objects can be used to press down on the U-shaped plate to improve its fulcrum stability. Then, the construction personnel choose whether to hold the auxiliary handle and apply downward pressure using the pry handle. As the pry handle 3 is pressed down, the telescopic rod drives the pry bar to rotate at the hinge of the support leg. The W-shaped hook of the pry bar can hold the pre-reserved reinforcement bar. Using the lever principle of the pry bar, the construction personnel can easily adjust the height and position of the pre-reserved reinforcement bar. As needed, the above steps can be repeated to adjust the position of other pre-reserved reinforcement bars at wet joints. If the device needs to be moved to another location for storage after adjustment, the construction worker can pull out the pin of the pry bar and rotate it upwards to rest it on the auxiliary handle. The corresponding support leg will also rotate with the pry bar and be held in place on the pry bar by the slotted U-shaped plate, thereby achieving the folding of the pry bar and support leg, and then moving it by the running wheels. This design not only facilitates the movement of the entire assembly but also protects the pry bar from damage.

[0020] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of this technical solution, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
