Abstract

(57) [Summary] (Modified) Generally, reinforced concrete structures are vertical, horizontal, and parallel raising methods. Therefore, when a horizontal force such as an earthquake is applied,
This device, in which the power of beams and columns is large, has a column arrangement and a beam erection direction in a crossed structure, forming a triangular group that is also the basis of the structure. [Purpose] Plan to reduce the construction cost. The physical space is the same as that of the vertical and horizontal bridges, and it is used as a co-help point for adjacent parts to avoid partial size. [Structure] The means of construction is not different from ordinary reinforced concrete structures. This will shorten the construction period.

Description

[Detailed description of the device] [Field of use of the device] Reinforced concrete structure that has a required flat space regardless of the pillar shape like the foreground of the field. It is possible to install it, put a fluid mixed with aggregate, cement, water, etc. in the temporary frame, and remove the temporary frame after the concrete has hardened. Therefore, the construction period becomes longer. [Problems to be solved by the invention] The seismic force and wind pressure applied to a building are to be concentrated on the floor. Therefore, bending moment stress occurs in vertical and horizontal vertical and parallel bridges. When the arrangement of legs is crossed as shown in [Fig. 1], each beam has only axial force and four-sided wall frame. When reaching the bridge, the stress of beams and columns becomes even and small. [Operation] The floor slab eliminates the temporary frame by placing the primary concrete, and the secondary concrete becomes integral with the adjacent part due to the extra length of the reinforcing bar (4). [Effect of the invention] Reduction of temporary frame cost, reduction of the amount of rebar and flat bar arrangement, shortening of construction period, beautiful composition

[Brief description of drawings]

FIG. 1 is a plan view showing a floor slab, a beam, and a column of a reinforced concrete structure. A is a floor slab, B is a beam, and C is a middle column.

FIG. 2 is a plan view showing the bar arrangement of the floor slab (A), is the main rebar 2 of the upper string, is the main rebar 3 of the lower string, and is the web rebar connecting the intersection of (1) and the intersection of (2). 4 is the extra length of the rebar. Extra length rebar to be integrated with the adjacent version.

[Fig. 3] Partial cross-sectional view showing the arrangement of floor slabs. Hardening of a us-beam below the primary concrete. Excluding as a temporary frame. Excluding secondary concrete. Full-thickness concrete placement. Preventing buckling of reinforcing bars.

FIG. 4 is a cross-sectional view showing the connection between the rack (B) and the floor slab A.

Claims (1)

[Scope of utility model registration request] 1. As shown in FIG. 1 [FIG. 1], the pillar shape of the middle part of the building is made ◇ shape, and as shown in [FIG. 1], the beams erected on each pillar are cross-shaped. Arrangement 3, as shown in [Fig. 1], each floor slab is almost rectangular 4, and as shown in [Fig. 2], the main muscles of the floor slab are vertical and horizontal, and the intersections of the upper chord and lower chords are diamond-shaped. The floor is constructed by arranging so that it becomes the center point of the concrete, and the concrete structure of the reinforcing bar composed of the reinforcing bars formed by connecting the upper and lower intersections and the web bars to each other.
