Embodiment 1

[0079] Such as Figure 1-Figure 3 As shown, the present embodiment discloses a reinforced end plate. The end plate 1 is in the shape of an outer circle and an inner circle as a whole, that is, the overall shape of the end plate 1 is circular in a front view. In this embodiment, the end plate 1 may also be polygonal and solid as a whole.

[0080] The plate body of the end plate 1 is provided with a welding surface 12 and 12 anchor holes 11 passing through the plate body. The welding surface 12 is arranged on the outside of the end plate 1 and is arc-shaped. The anchor hole 11 includes a tension screw hole 111 and The steel bar anchor hole 112 and the tension screw hole 111 are arranged on the outside of the steel bar anchor hole 112, and the inner wall of the tension screw hole 111 is provided with a tension thread. The centerline of the tension screw hole 111 coincides with the centerline of the steel bar anchor hole 112 . The tensioning screw hole 111 and the steel bar anch...

Embodiment 2

[0087] Such as Figure 4 As shown, this embodiment discloses a reinforced end plate, wherein the end of the steel anchor hole 112 near the inner side of the end plate (ie, the bottom of the small mouth of the steel anchor hole 112) is provided with a bevel 15; the end plate is in contact with the concrete. The cross-section of the end plate is larger than the cross-sectional area of ​​the other side of the end plate, so that the end of the end plate close to the concrete forms a clamping platform 14. The rest of the technical features are the same as those in Embodiment 1, and will not be repeated here.

[0088] The oblique angle in this embodiment refers to the oblique angle in the cross-sectional view. In the actual structure, this position is presented as a trumpet-shaped channel with a small top and a large bottom. The bevel 15 is set at the small mouth of the reinforcement anchor hole 112, which can play a guiding role when the reinforcement is threaded, so as to facilit...

Embodiment 3

[0090] Such as Figure 5 As shown, this embodiment discloses a reinforced end plate, wherein the anchor hole 11 of the end plate 1 is provided with a boss 16, and the boss 16 protrudes toward the end of the end plate 1 close to the concrete. The rest of the technical features are the same as those in Embodiment 1, and will not be repeated here.

[0091] Specifically, the boss 16 is located on the inner side of the end plate, the centerline of which coincides with the centerline of the anchor hole 11 , and the boss 16 partially surrounds the reinforcement anchorage hole 112 . The height of the reinforcement anchor hole 112 is greater than the thickness of the boss 16 , and the transverse dimension of the boss 16 is greater than the transverse dimension of the tension screw hole 111 . The shape of the boss 16 is not limited to a cylinder or a cuboid. In this embodiment, the boss 16 is cylindrical. By setting the boss on the side of the end plate 1 close to the concrete, on the...

Abstract

The invention relates to an enhanced end plate. A plurality of anchoring holes penetrating through a plate body are formed in the plate body of the end plate; the anchoring holes comprise tensioning screw holes and steel bar anchoring holes, the tensioning screw holes are formed in the outer sides of the steel bar anchoring holes, and the center lines of the tensioning screw holes coincide with the center lines of the steel bar anchoring holes. The invention further relates to an enhanced precast pile. According to the end plate, existing paddle-tumbles or rib grooves formed in an end plate are abandoned, the tensioning screw holes and the steel bar anchoring holes are formed in the same axis, and thus the contact area between a steel bar upset head and an anchoring plate is expanded, and the anchoring performance of a steel bar and the anchoring plate is effectively improved; and according to the precast pile, mechanical connection between the steel bar and the anchoring plate is achieved through the end plate, the steel bar and the like, the pile has the characteristics of being simple in structure, high in pulling resistance and horizontal bearing capacity, excellent in performance of the end plates at the two ends of the pile, low in manufacturing cost, high in construction efficiency and the like, and the requirements for economical efficiency and safety in the production process can be met.

Description

technical field [0001] The invention relates to the field of prefabricated component production, in particular to a reinforced end plate and a prefabricated pile. Background technique [0002] With the improvement of the importance of modern buildings and the continuous increase of building height, higher requirements are placed on the bearing capacity of the foundation. The natural foundation can no longer bear the load from the upper building, and concrete piles are used to make The foundation piles of the foundation are formed by pressing the piles into the ground with a pile driver to allow the upper part of the foundation piles to carry the building. [0003] In the technical scheme of Chinese patent CN202023189U and title "a hollow square pile of foundation concrete", the two ends of the pile are provided with metal end plates connected with the reinforcement cage, and the metal end plates are provided with threading holes and tension holes, and the threading holes are...
