Description

Technical Field

[0001] The utility model belongs to the technical field of square pile connectors, and in particular relates to a square pile connection structure without an end plate. Background Art

[0002] The full name of prestressed pile is reinforced concrete prestressed pipe pile. It is prefabricated in a prefabricated component processing plant, maintained, and after reaching the designed strength, it is transported to the construction site, driven into the soil by a pile driver, and then the cap beam (slab) foundation is poured on the top of the pile. There are various types of prestressed piles. From the shape, there are round piles with a round cross-section and square piles with a square cross-section. From the structural point of view, there are also prestressed piles with end plates and prestressed piles without end plates. Prestressed piles with end plates can be connected to prestressed piles using the connection holes on the end plates to form prestressed piles with longer lengths to meet the needs of the design requirements of the construction site. This type of prestressed pile with end plates is expensive. Prestressed piles without end plates are low in cost, but when you want to connect the prestressed piles in sequence, you need to use connectors to connect them. The existing square piles without end plates have a complex connection structure, especially the limited operating space required to operate tools to turn bolts, nuts, etc., which is very inconvenient to operate, and the connector has low structural strength and poor shear resistance.
