Description

Technical Field

[0001] This utility model relates to the field of square pile end plate technology, specifically a high-strength square pile end plate. Background Technology

[0002] The end plate of a square pile is an important component used to seal both ends of the pile body during the production of precast concrete square piles. It is usually made of steel plate. During construction, when connecting the end plates of two precast square piles at one end, welding is usually used for fixing. However, before welding, the surface of the end plate needs to be cleaned of impurities such as rust and oil. During the welding process, layer welding is required, which takes a long time for welding a single pile, affecting the overall construction progress. Moreover, the welding quality depends on the welder's skill level. If the operation is not done properly, defects such as slag inclusion, porosity, lack of fusion, undercut, and insufficient weld size can easily occur. Therefore, we propose a high-strength square pile end plate to solve the above problems. Utility Model Content

[0003] (a) Technical problems to be solved

[0004] To address the shortcomings of existing technologies, this utility model provides a high-strength square pile end plate, which solves the problems mentioned in the background section.

[0005] (II) Technical Solution

[0006] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0007] A high-strength square pile end plate includes an upper end plate and a lower end plate, the upper end plate and the lower end plate being tightly fitted together. The top of the lower end plate has four guide grooves, each of which has a spring fixed inside. One end of each spring is fixed with a lower locking block adapted to the guide groove. The bottom of the upper end plate has four upper locking blocks adapted to the guide grooves and the lower locking blocks, and the upper locking blocks are respectively engaged with the corresponding lower locking blocks.

[0008] Furthermore, the bottom of the upper end plate is provided with four recessed grooves, and the top of the lower end plate is fixed with four protrusions that are adapted to the recessed grooves.

[0009] Furthermore, the top of both the upper and lower end plates are provided with eight sets of connection holes, each set of connection holes including a bolt hole and a locking hole.

[0010] Furthermore, a central hole is provided at the center position of both the upper end plate and the lower end plate.

[0011] Furthermore, L-shaped reinforcing ribs are fixed at the top four corners of the lower end plate, and slots that match the L-shaped reinforcing ribs are provided at the four corners of the upper end plate.

[0012] Furthermore, all the springs are made of stainless steel.

[0013] (III) Beneficial Effects

[0014] Compared with the prior art, this utility model provides a high-strength square pile end plate, which has the following beneficial effects:

[0015] This utility model connects and fixes the upper and lower end plates by snap-fitting. Since the snap-fitting component is a prefabricated part, the upper and lower end plates only need to be aligned and snapped together on site to connect and fix them. This avoids the risks of electric arc radiation, high-temperature welding slag and fire caused by welding. It is especially suitable for construction in flammable and explosive environments or rainy and snowy weather, and improves the efficiency, flexibility and safety of square pile end plate connection.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example

[0023] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown in the figure, an embodiment of the present invention provides a high-strength square pile end plate, including an upper end plate 1 and a lower end plate 2. The upper end plate 1 and the lower end plate 2 are tightly fitted together. The top of the lower end plate 2 is provided with four guide grooves 3, and each guide groove 3 is fixed with a spring 4. The springs 4 are all made of stainless steel. Stainless steel springs 4 have excellent wear resistance, anti-aging properties, and corrosion resistance, and their service life is longer. One end of each spring 4 is fixed with a lower locking block 5 that matches the guide groove 3. The bottom of the upper end plate 1 is fixed with four upper locking blocks 6 that match the guide grooves 3 and the lower locking blocks 5. The upper locking blocks 6 are respectively engaged with the corresponding lower locking blocks 5. During the process of connecting two square piles, when the upper end plate 1 and the lower end plate 2 are aligned and moved downwards, the bottom end of the upper locking block 6 will enter the interior of the guide groove 3. As the upper locking block 6 moves downwards, it will squeeze the lower locking block 5 to one side. After the lower locking block 5 moves, the spring 4 will be in a compressed state. When the upper locking block 6 moves to its maximum extent, the compression on the lower locking block 5 will be released. Then, under the action of the spring 4, the lower locking block 5 can be pushed to reset. At this time, under the action of the reset lower locking block 5, the upper locking block 6 can be limited, thereby achieving the connection and fixation of the two, avoiding the reduction of construction efficiency due to welding fixation when the two are connected.

[0024] like Figure 3 and Figure 4 As shown, in some embodiments, the bottom of the upper plate 1 is provided with four recessed grooves 8, and the top of the lower plate 2 is fixed with four protrusions 9 that are adapted to the recessed grooves 8. Through the cooperation of the recessed grooves 8 and the protrusions 9, the stability of the connection between the upper plate 1 and the lower plate 2 can be improved.

[0025] like Figure 3 and Figure 4 As shown, in some embodiments, the top of both the upper end plate 1 and the lower end plate 2 are provided with eight sets of connecting holes 10. Each set of bolt holes 10 includes a connecting hole 1001 and a locking hole 1002. By using the bolt holes 1001 and locking holes 1002, the upper end plate 1 and the lower end plate 2 can be connected, and the two can be reinforced again as needed.

[0026] like Figure 1 and Figure 3 As shown, in some embodiments, a central hole 7 is provided at the center of both the upper end plate 1 and the lower end plate 2. The central hole 7 can reduce the rigid contact area at the center of the end plate, so that the stress can be evenly diffused to the periphery, avoid the failure of the square pile end plate due to local crushing in the central area, and provide a small deformation space to release the concrete shrinkage stress and reduce the risk of the end plate separating from the pile body.

[0027] like Figure 3 and Figure 4As shown, in some embodiments, L-shaped reinforcing ribs 11 are fixed at the top four corners of the lower end plate 2, and slots 12 adapted to the L-shaped reinforcing ribs 11 are opened at the four corners of the upper end plate 1. Through the cooperation of the L-shaped reinforcing ribs 11 and the slots 12, the upper end plate 1 and the lower end plate 2 can play a guiding role when connected, thereby facilitating the precise engagement of the upper locking block 6 and the lower locking block 5.

[0028] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
