Description

TECHNICAL FIELD The present invention relates to a frame structure of columns and beams in a self-propelled multi-storey parking lot.

[Conventional technology]

Conventionally, the plane shape of the hoistway in a self-propelled multi-storey parking lot is generally divided into A, B, and C in FIG. 5, and parking zones D, E, and F are formed on the outer periphery thereof.

Looking at the divided part of A, for example, which is divided in this way, it is a trapezoid consisting of a long side G and a short side H, points I and J are at the same height, and points K and L are at the same height. Therefore, this division A
The floorboard of the car has a twisted surface. Therefore, it is difficult to form this floorboard with one precast concrete floorboard (hereinafter referred to as PC floorboard), and therefore it is generally cast with cast-in-place concrete.

Therefore, the applicant of the present invention connects a plurality of isosceles PC floor plates M as shown in FIG. 6 in order to form the hoistways A to C with the PC floor plates for the purpose of shortening the construction period. We proposed a floorboard structure in which each joint is twisted to form a hoistway (Japanese Patent Application No. 2-122553).

[Problems to be Solved by the Invention]

By the way, when the floorboard is formed of the PC floorboard as described above, the pillars and beams are arranged on the module grid line N indicated by the chain line as shown in FIG. Desirable for forming.

However, there is a restriction that the width O of the hoistway is regulated, and that the girder 1 of the hoistway is arranged on the radiation of equally divided angles at the center point P of the circular hoistway. When the girder 1 is linearly formed from the inside Q to the outside point R in the hoistway, the points Q and R deviate from the intersection of the module grid lines N as shown in FIG. The girders 2 and 3 of the belt D and the inner peripheral parking belt D ′ deviate from the module grid line N, and the inner and outer columns 4 and
4a also deviates from the intersection of the module grid lines N. Therefore, there is a problem that a uniform PC floor board that is grit-divided cannot be placed.

Therefore, the present invention is constructed with a uniform PC floor plate in which the pillars are arranged at the intersections of the module grid lines and the large beams of the parking band are arranged on the module grid lines, and the floor plate of the parking band is grit-split. The purpose is to propose a frame structure of possible columns and beams.

[Means for Solving the Problems]
