Description

Technical Field

[0001] This utility model relates to the field of square pile end plate technology, specifically to an end plate structure for a concrete pull-out resistant square pile. Background Technology

[0002] Concrete tension square piles are a special type of pile foundation structure, mainly used to resist upward tensile forces to ensure that buildings or structures will not float or shift under certain conditions due to external forces. This type of pile is widely used in scenarios that require overcoming buoyancy, such as underground garages, caisson foundations, and bridge anchorages. When connecting two square piles, end plates are required. Generally, the two end plates are connected by welding or bolting, which is quite cumbersome. Therefore, we propose an end plate structure for concrete tension square piles to solve the above problems. Utility Model Content

Hollow corner blocks are fixed at the top four corners of the upper end plate and the bottom four corners of the lower end plate. Each hollow corner block has a fixing hole on one side wall, and anti-disengagement positioning components are inserted into two corresponding fixing holes.

[0008] Furthermore, the anti-detachment positioning component consists of a connecting plate and two anti-detachment blocks. One end of each anti-detachment block is fixedly connected to the connecting plate, and the other end of each anti-detachment block is respectively limited and locked inside the corresponding fixing hole.

[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 discloses an end plate structure for a concrete pull-out square pile, including an upper end plate 1 and a lower end plate 2. Both the lower edge of the upper end plate 1 and the upper edge of the lower end plate 2 are provided with weld overlay chamfers 9. Through these weld overlay chamfers 9, when the connected upper end plate 1 and lower end plate 2 need to be fixed by welding, the welding material can fill the interior of the weld overlay chamfers 9. The top of the upper end plate 1 has four positioning holes 3, and the top of the lower end plate 2 is fixed with four positioning pins 4 that are compatible with the positioning holes 3. The positioning pins 4 are tightly inserted into the corresponding positioning holes 3. Hollow corner blocks are fixed at the top four corners of the upper end plate 1 and the bottom four corners of the lower end plate 2. 5. Each side wall of the hollow corner block 5 is provided with a fixing hole 6. A corresponding anti-detachment positioning component 7 is inserted into the two fixing holes 6. In the process of using this concrete pull-out square pile end plate structure, the upper end plate 1 and the lower end plate 2 are fixed to the square pile respectively. When connecting and fixing the two, the upper end plate 1 and the lower end plate 2 can be inserted. At this time, the positioning hole 3 and the positioning clip 4 are used to enable the two to play a pre-positioning role when connecting. After the two are pre-positioned and connected, the corresponding hollow corner blocks 5 at the upper and lower positions can be connected and fixed by the anti-detachment positioning component 7. When the anti-detachment positioning components 7 at the four corner positions are installed, the fixed connection of the upper end plate 1 and the lower end plate 2 can be completed.

[0024] like Figure 1 and Figure 4 As shown, in some embodiments, the anti-detachment positioning component 7 consists of a connecting plate 701 and two anti-detachment blocks 702. A reinforcing strip 703 is fixed to one side wall of the connecting plate 701. The surface of the reinforcing strip 703 is provided with an arc-shaped groove 704. The reinforcing strip 703 enhances the deformation resistance of the connecting plate 701, preventing deformation caused by striking the connecting plate 701 during installation. The arc-shaped groove 704 allows the reinforcing strip 703 to better resist bending deformation. One end of each anti-detachment block 702 is fixedly connected to the connecting plate 701, and the other end of each anti-detachment block 702 is respectively limited and engaged inside the corresponding fixing hole 6. After the upper end plate 1 and the lower end plate 2 are connected and fixed, the two anti-detachment blocks 702 on the connecting plate 701 can be positioned at the two corresponding fixing holes 6. Then, the anti-detachment blocks 702 can be hammered into the inside of the fixing holes 6. Since the anti-detachment blocks 702 have an adjustment groove, they will be squeezed when they enter the inside of the fixing holes 6, and then they can pass through the fixing holes 6. After passing through the fixing holes 6, they will be released from the squeezing restriction, and then the anti-detachment blocks 702 will reset. Since its surface is provided with a limiting boss structure, the anti-detachment blocks 702 can play an anti-detachment role when they are locked inside the fixing holes 6.

[0025] like Figure 2 and Figure 3As shown, in some embodiments, the top of the lower end plate 2 is fixed with an auxiliary retaining ring 8 that is adapted to the upper end plate 1. By using the auxiliary retaining ring 8, the upper end plate 1 and the lower end plate 2 can be connected to further limit the lateral movement of the two.

[0026] like Figure 1 As shown, in some embodiments, an adhesive layer 10 is provided between the upper end plate 1 and the lower end plate 2. When the upper end plate 1 and the lower end plate 2 are connected, the adhesive layer 10 helps to connect the two more tightly into a whole, further enhancing the stability of the connection.

[0027] 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.
