Description

Technical Field

[0001] The present application relates to the field of building material accessories, and in particular to an end plate structure with a firm connection. Background Art

[0002] The head plate is a disc-shaped part, often used in pairs, and is set at the end of the concrete pipe pile to connect and fix two concrete pipe piles. In the existing pile connection process, it is necessary to keep the axis of the new pile section consistent with the original pile section, and the dirt, oil stains, rust, etc. on the welding surface of the two end plates must be cleaned in advance before welding and connecting the piles. The pipe pile welding construction requires multiple experienced welders with professional welder certificates to carry out the work in accordance with the requirements of technical regulations. The welding procedure of the entire pile connection process is complicated and cumbersome, and requires high labor and time costs, which affects the efficiency of pile connection. Therefore, there are many end plate structures on the market that use mechanical connection instead of welding.

[0003] Announcement No. CN215367237U discloses a flange bolt-locked end plate, which has a larger outer diameter than an ordinary end plate, and is provided with a number of corresponding through holes (or U-shaped through holes) along the edges of its outer edge. During construction, an appropriate number of high-strength bolts and nuts made of the same steel are arranged. During pile connection construction, the through holes on the outer edges of the upper and lower pile end plates are aligned and overlapped, or a number of positioning pins are used to guide the upper and lower piles to align and overlap, and the upper and lower pile end plates are locked and connected along the outer sides with a number of high-strength bolts and nuts to complete the pile connection. This replaces the process of welding the upper and lower end plates by ordinary welding. The bolt connection construction operation is simple, convenient, efficient, fast, low-cost and reliable.

[0004] However, there are some defects in the above scheme: the above scheme requires multiple bolts for installation and connection, and relies on bolts to ensure the connection strength, which wastes time in installation, and multiple bolts need to be carefully stored. If the bolts are accidentally lost, it will undoubtedly increase the cost. Utility Model Content

[0033] See also Figure 1 , 2 , 3 and 4, the lower end plate assembly 200 includes a lower connecting plate 210, a block 220 and a threaded rod 230, the lower connecting plate 210 is provided with a connecting groove 211, the block 220 is slidably set in the connecting groove 211, the threaded rod 230 of the lower connecting plate 210 passes through the connecting groove 211, and the block 220 is threadedly sleeved on one end of the threaded rod 230, the block 220 is inserted into the outer side of the extension ring plate 120, and the upper connecting plate 110 and the lower connecting plate 210 are both provided with steel bar holes 240.

[0034] In this embodiment, the connecting groove 211 includes a receiving groove 2111 and a through hole 2112, and the threaded rod 230 is rotatably set in the receiving groove 2111 and the through hole 2112. The block 220 and the receiving groove 2111 are adapted to each other. The receiving groove 2111 and the through hole 2112 are set to accommodate and install the threaded rod 230.

[0035] In this embodiment, the threaded rod 230 includes a threaded head 231 and a rotating rod 232. The threaded head 231 is located in the accommodating groove 2111, and the rotating rod 232 rotates through the through hole 2112. By setting the threaded head 231 and the rotating rod 232, the rotating rod 232 drives the threaded head 231 to rotate, and the threaded head 231 rotates in the accommodating groove 2111.

[0036] In a specific implementation, the clamping block 220 is provided with a thread groove 221 , and the thread head 231 is threadedly connected to the thread groove 221 . The thread head 231 and the clamping block 220 are threadedly connected by providing the thread groove 221 for threaded connection.

[0037] It should be noted that a positioning block 213 is provided on the top of the lower connecting plate 210, and a positioning groove 112 is provided on the bottom of the upper connecting plate 110.
