Embodiment Construction

[0046] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0047] refer to figure 1 , shows a three-dimensional structural schematic view of the super-high and large-curvature circular spiral clear water staircase of the present invention. The super-high and large-curvature circular spiral clear-water staircase of the present invention belongs to the fair-faced concrete construction technology, wherein the spiral staircase is attached to a circular wall, and the spiral staircase, the spiral staircase handrail and the circular wall are all fair-faced concrete structures, which are formed by one-time pouring. The height of the circular wall is high, and it is a variable cross-section structure. When the circular wall formwork is supported, the arc-shaped steel frame of the circular wall formwork is supported by the tension bolts set perpendicular to the arc-shaped back-flute. The curved surface is stagg...

Abstract

The invention relates to a construction method of an ultrahigh large-curvature circular spiral as-cast-finish stair. The method includes the steps of forming an as-cast-finish concrete circular wall, erecting a spiral stair flight formwork on the inner side face of the circular wall, erecting a spiral stair railing formwork, and pouring as-cast-finish concrete in the spiral stair flight formwork and the spiral stair railing formwork to form a spiral stair flight and a spiral stair railing. The as-cast-finish circular wall is firstly formed to serve as the attachment basis of the spiral stair flight, and the difficulty for erecting the spiral stair flight formwork is lowered.

Description

technical field [0001] The invention relates to the field of building construction, in particular to a construction method for a super-high and large-curvature circular spiral clear water staircase. Background technique [0002] Fair-faced concrete, also known as decorative concrete, belongs to one-time pouring molding, without any external decoration, and directly uses the natural surface effect of cast-in-place concrete as the finish, so it is different from ordinary concrete, with smooth surface, uniform color, sharp edges and corners, and no damage And pollution, appear natural and rustic. [0003] The construction requirements of fair-faced concrete are strict. It is a one-time pouring molding structure. It has high requirements for the tightness of the supporting formwork, the flatness of the surface, the division and effect of the joints, and the effect of clear water for the joints. At present, the fair-faced concrete construction is mostly used for flat As for the ...
