Description

Technical Field

[0001] This application relates to the technical field of building construction connections, and in particular to a device for rapid construction connection of anchor bolts of different specifications to support steel frames. Background Technology

[0002] Currently, underground engineering construction has always been an important component in the field of engineering construction. Projects such as mine roadways and tunnels have a crucial impact on resource development and transportation construction. With the continuous development of underground engineering, the requirements for the stability and construction efficiency of support structures are also increasing. A reasonable support structure can ensure the safety of underground engineering, reduce the occurrence of accidents such as collapses, and improve the safety of construction and the service life of the project. In the entire underground engineering system, the connection between anchor bolts and support steel frames is a key link in the support structure. The stability of the connection and the convenience of construction are directly related to the performance of the entire support system.

[0003] In previous underground engineering construction, some traditional connection methods were usually used to connect anchor bolts to support steel frames such as U-shaped steel and I-beams: one common practice is to use welding to directly weld the anchor bolts to the support steel frames, which can ensure the strength of the connection to a certain extent; another method is to use simple bolt connections to fix the anchor bolts and support steel frames with bolts; in addition, some simple clamp devices are used to achieve the connection between the two, and these clamp devices connect the anchor bolts and support steel frames by clamping.

[0004] However, the existing connection methods have obvious drawbacks: traditional connection methods are difficult to achieve rapid construction connection between anchor bolts of different specifications and support steel frames. When faced with anchor bolts of various specifications, a lot of time and effort is required to adjust the connection method, resulting in low construction efficiency and failing to meet the needs of rapid construction in modern underground engineering. Utility Model Content

[0005] In order to overcome the above problems, this application provides a device for rapid construction connection of anchor bolts of different specifications and support steel frames.

[0006] This application provides a rapid construction connection device for anchor bolts of different specifications and support steel frames, which adopts the following technical solution: A rapid construction connection device for anchor bolts of different specifications and support steel frames includes a support steel frame and an outer frame. The outer frame is vertically arranged and fixedly connected to the support steel frame. A clamping device is provided on the outer frame. Two sets of clamping devices are provided and are symmetrically arranged along the horizontal axis of the outer frame. The clamping device includes a clamping plate, a drive rod, and a mounting base. The mounting base is detachably connected to the outer frame. The clamping plate is fixedly connected to the drive rod. The drive rod passes through the mounting base. The mounting base is provided with a drive component for threaded connection with the drive rod.

[0007] By adopting the above technical solution, the outer frame and the support steel frame are fixedly connected to provide load-bearing and positioning functions. The two sets of symmetrically arranged clamping devices can stably clamp the anchor bolts. The mounting base and the outer frame are detachably connected to facilitate the installation and replacement of the device. The drive component and the drive rod are threadedly connected. By rotating the drive component, the drive rod can be moved, which in turn moves the clamping plate to achieve rapid clamping of anchor bolts of different specifications, thereby realizing the rapid construction connection of anchor bolts of different specifications to the support steel frame.

[0008] Optionally, the outer frame is provided with horizontal sliding holes at both the top and bottom, and multiple mounting holes are provided at intervals on both sides of the sliding holes. Two mounting plates are symmetrically fixed on the mounting base, and bolts are provided on the mounting plates. The bolts pass through the mounting holes and are detachably connected to the outer frame.

[0009] By adopting the above technical solution, the outer frame is fixedly connected to the support steel, which can play a role in bearing and positioning; the two sets of symmetrically arranged clamping devices can clamp the anchor rod more stably; the outer frame is opened with sliding holes and mounting holes on both sides, and the mounting seat is detachably connected to the outer frame through mounting plate and bolts, which makes it easy to adjust the position of the mounting seat according to the actual situation, and realize the rapid construction connection of anchor rods of different specifications to the support steel frame.

[0010] Optionally, the driving component is rotatably connected to the mounting base, and the rotation axis of the driving component is in the vertical direction. A threaded block is fixed inside the driving component, and the threaded block is threadedly connected to the driving rod. A slider for guiding and limiting the driving rod is provided inside the mounting base.

[0011] By adopting the above technical solution, the driving component can rotate flexibly. By utilizing the threaded engagement between the threaded block and the driving rod, the rotation of the driving component can be converted into the linear motion of the driving rod. At the same time, the slider guides and limits the driving rod, making the movement of the driving rod more stable. This allows the clamping device to perform clamping operations on the anchor rod more accurately and stably, thereby improving the working reliability of the connecting device.

[0012] Optionally, the mounting base has a slide rail, the slider is fixed on the drive rod, and the slider slides vertically within the slide rail.

[0013] By adopting the above technical solution, a slide rail is opened in the mounting base, and the slider is fixed on the drive rod and made to slide vertically in the slide rail. This can guide and limit the drive rod, ensuring that the drive rod moves stably in the vertical direction. In turn, the clamping plate can accurately clamp the tail of the anchor bolt, realizing the rapid construction connection between anchor bolts of different specifications and the support steel frame.

[0014] Optionally, the depth of the slide gradually decreases from top to bottom along the vertical direction.

[0015] By adopting the above technical solution, the drive rod can be gradually restricted by the shallowing of the slide during the sliding process, which enhances the guiding and limiting effect of the drive rod, thereby improving the clamping stability and accuracy of the anchor rod by the clamping plate, so as to better realize the rapid construction connection of anchor rods of different specifications with the support steel frame.

[0016] Optionally, the width of the mounting base on the side closer to the outer frame is greater than the width on the side farther from the outer frame.

[0017] By adopting the above technical solution, the mounting base forms a stable support structure, which enhances the stability of the connection between the mounting base and the outer frame, thereby improving the stability and reliability of the entire connection device.

[0018] Optionally, the driving component has a movable cavity, and a limiting plate is fixed on the driving rod. The limiting plate slides vertically within the movable cavity.

[0019] By adopting the above technical solution, the movable cavity and the limiting plate can effectively limit the drive rod during vertical sliding, preventing the drive rod from deviating or shaking during movement, ensuring the stability and reliability of the clamping device, and thus facilitating the rapid construction connection of anchor rods of different specifications with the support steel frame.

[0020] Optionally, a spring is provided on the limiting plate, with one end of the spring fixed to the limiting plate and the other end fixed to the mounting base.

[0021] By adopting the above technical solution, the spring can provide buffering and elastic reset during the movement of the drive rod, enhance the stability and reliability of the connection device, and facilitate the rapid construction connection of anchor rods of different specifications with the support steel frame.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. The outer frame is fixedly connected to the support steel frame and is equipped with two sets of symmetrical clamping devices, which can be used for quick construction connection of anchor bolts of different specifications to the support steel frame; 2. The mounting base is detachably connected to the outer frame, which facilitates adjustment and replacement according to different construction conditions, improving construction flexibility; 3. The drive component is threadedly connected to the drive rod, which can easily drive the clamping plate, realize the quick clamping of the anchor rod, and improve construction efficiency.

[0025] The following is in conjunction with the appendix Figures 1-3 This application will be described in further detail.

[0026] This application discloses a device for rapid construction connection of anchor bolts of different specifications and support steel frames.

[0027] refer to Figure 1 A rapid construction connection device for anchor bolts of different specifications and support steel frames includes a support guard 1, which is vertically set. A connecting plate is welded and fixed on the side flange of the support guard 1. An outer frame 2 is set on the connecting plate. The outer frame 2 is detachably connected to the connecting plate by bolts. The outer frame 2 is vertically set. Two sets of clamping devices 3 are symmetrically set on the upper and lower sides of the outer frame 2 along the horizontal axis.

[0028] refer to Figure 2 The outer frame 2 has a rectangular frame structure, and sliding holes 21 are provided at the top and bottom respectively. The sliding holes 21 are horizontally set, and multiple mounting holes are provided on both sides of the sliding holes 21 along their own length direction. The mounting base 33 has a frustum-shaped design, which can increase the stability of the connection and reduce stress concentration.

[0029] refer to Figure 1 The clamping device 3 includes a clamping plate 31, a drive rod 32, and a mounting base 33. Mounting plates 331 are symmetrically fixed on both sides of the mounting base 33. Mounting bolts are provided on the mounting plates 331 and pass through the mounting holes, so that the mounting base 33 can be detachably connected to the outer frame 2. The clamping plate 31 is arc-shaped and is fixedly connected to the drive rod 32. A drive component 4 is provided on the mounting base 33. The drive rod 32 passes through the mounting base 33 and the drive component 4. The two drive rods 32 and the clamping plate 31 move in directions that are closer to or further away from each other.

[0030] refer to Figure 2 and Figure 3 The driving component 4 is rotatably connected to the mounting base 33, and the rotation axis of the driving component 4 is vertical. The overall cross-section of the driving component 4 is T-shaped, and a threaded block 41 is fixed inside. A movable cavity 42 is opened below the threaded block 41. The threaded block 41 is threadedly connected to the driving rod 32. A slide rail 332 is vertically opened inside the mounting base 33. A slider 321 is fixed on the side wall of the driving rod 32. The slider 321 slides vertically in the slide rail 332, and the depth of the slide rail 332 gradually decreases from top to bottom. When the driving component 4 is rotated, the threaded block 41 and the driving rod 32 move threadedly. Under the limiting and guiding action of the slider 321, the driving rod 32 moves vertically. During the process of the clamping plate 31 gradually clamping, the slider 321 gradually abuts against the inner wall of the slide rail 332, which helps to increase the stability of the clamping plate 31 and the driving rod 32 and improve the clamping effect.

[0031] refer to Figure 2 and Figure 3 A limiting plate 5 is coaxially fixed on the drive rod 32. The limiting plate 5 slides vertically within the movable cavity 42. A spring 6 is provided on the limiting plate 5. One end of the spring 6 is fixed to the limiting plate 5, and the other end is fixed to the mounting base 33. As the clamping plate 31 gradually clamps, the limiting plate 5 moves toward the outer frame 2, gradually compressing the spring 6 until it moves to the maximum range of the movable cavity 42, which is the maximum range that the clamping plate 31 can move. The limitation of the movable cavity 42 can provide a certain range for the movement of the clamping plate 31 and the drive rod 32, preventing the clamping force of the clamping plate 31 from being too large and causing damage to the clamped object. During this process, the spring 6 continuously provides vibration damping and buffering.

[0032] The implementation principle of a rapid construction connection device for anchor bolts of different specifications and support steel frames in this application embodiment is as follows: In actual construction, the outer frame 2 is first fixed on the flange of the support steel frame to achieve load bearing and positioning. Then, according to the specifications of the anchor bolt, the position of the mounting seat 33 on the outer frame 2 is adjusted by bolts. Next, the driving component 4 is rotated. Since the threaded block 41 inside the driving component 4 is threadedly connected to the driving rod 32, the driving rod 32 will move up and down along the slide rail 332 under the guide limit of the slider 321, thereby driving the clamping plate 31 to move and achieve clamping of the anchor bolt. The setting of the spring 6 and the limiting plate 5 ensures the stability and safety of the movement of the driving rod 32. This connection device can quickly adapt to anchor bolts of different specifications, greatly improves construction efficiency, and has obvious advantages compared with traditional connection methods.

[0033] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
