Problems solved by technology

In areas with high seismic fortification requirements, the building foundation not only meets the requirements of vertical compressive load, but also meets the requirements of seismic fortification, which requires the piles in the building foundation to meet the requirements of vertical compression and earthquake resistance at the same time. The poured circular concrete prefabricated piles have been calculated and designed. Although they can be satisfied at the same time, the pouring on site will cause great pollution to the environment, and the construction period is long and the cost is high. The factory prefabricated prestressed high-strength concrete centrifugal piles have h

Example Embodiment

[0011] The detailed structure of the present invention will be further described below in conjunction with the drawings and specific embodiments.

[0012] Such as figure 1 , figure 2 As shown, an elliptical prefabricated column includes a column body 2 and a lifting plate 1 fixed on the upper end of the column body 2. The upper end of the lifting plate 1 is provided with a lifting ring 11, and the lifting plate 1 and a steel frame provided inside the column 2 Connected, the cross section of the cylinder 2 is elliptical.

[0013] The steel frame includes pre-stressed steel bars 32 and non-pre-stressed steel bars 34. The pre-stressed steel bars 32 are connected into one body through an outer steel frame cage 31, and the non-prestressed steel bars 34 are connected into one body through an inner steel frame cage 33. The pre-stressed steel bars 32 The upper end of the is connected with the lifting plate 1.

[0014] The outer steel frame cage 31 and the inner steel frame cage 33 are con...

Abstract

The invention discloses an oval building prefabricated column. The oval building prefabricated column comprises a column body (2) and a hoisting plate (1) fixed to the upper end of the column body (2). A hoisting ring (11) is arranged at the upper end of the hoisting plate (1). The hoisting plate (1) is connected with a reinforcement cage arranged in the column body (2). The cross section of the column body (2) is oval. The reinforcement cage comprises prestressing tendons (32) and non-prestressing tendons (34). The prestressing tendons (32) are connected into a whole through an outer reinforcement cage (31). The non-prestressing tendons (34) are connected into a whole through an inner reinforcement cage (33). The upper ends of the prestressing tendons (32) are connected with the hoisting plate (1). The oval building prefabricated column has the beneficial effects that the horizontal bearing capacity, the bending resistance and the deformation performance of the column body are improved, and ductility is improved to a great extent.

Description

technical field [0001] The invention relates to a pile material for construction, in particular to an elliptical building prefabricated column. Background technique [0002] With the increasing importance of modern buildings and the continuous increase of building heights, higher requirements are placed on the performance of building foundations. In areas with high seismic fortification requirements, the building foundation not only meets the requirements of vertical compressive load, but also meets the requirements of seismic fortification, which requires the piles in the building foundation to meet the requirements of vertical compression and earthquake resistance at the same time. The poured circular concrete prefabricated piles have been calculated and designed. Although they can be satisfied at the same time, the pouring on site will cause great pollution to the environment, and the construction period is long and the cost is high. The factory prefabricated prestressed ...
