Narrow long plane concrete honeycomb type space lattice box type structure and manufacturing method

[0027] Example 1

[0028] Such as Figure 1 to Figure 5 As shown, the narrow and long plane concrete honeycomb space grid box structure includes a multi-layer, long-span, narrow and long plane concrete honeycomb hollow sandwich slab floor and concrete grid frame columns. The long sides Lx and The Ly supports on the side of the span are rigidly connected with the surrounding concrete grid frame columns to form a spatial grid box system; among them, each layer of large-span narrow-long plane concrete honeycomb hollow sandwich slab floor cover is divided into upper chord layer and lower chord layer The lower chord layer is composed of lower chord beams to form a plurality of regular hexagonal honeycomb grids, the long side Lx of the narrow and long plane is a multiple of the side length b of the honeycomb grid, and b+2b=3b from the left and right ends Arrange to the center of the long side, and the span side Ly of the narrow and long plane is a multiple of the honeycomb grid height 2h, that is, the increase or decrease size of the long side Lx should be a multiple of 3b, and the span side Ly increases or decreases the size Should be a multiple of 2h, the upper chord layer is composed of upper chord beams that form the same regular hexagonal grid and cast-in-place reinforced concrete floor slabs on the upper surface of the upper chord beam. The upper chord beams and the lower chord beams form multiple regular hexagonal honeycomb meshes that are the same up and down The vertical member shear key is rigidly connected with the intersection of the upper and lower chord hexagons, and the upper chord layer, the lower chord layer and the shear key form a space sandwich panel; the honeycomb grid hollow beam of the floor is clamped in the floor plane It is distributed in three directions at an angle of 60°, and is rigidly connected with the long side Lx and the span side Ly of the grid frame structure to form a lateral force-resistant structure, forming a new structural system with extremely high lateral stiffness; the concrete grid frame includes supports distributed on supports A plurality of uprights at a location and a plurality of beams connecting adjacent uprights, the beams include a main beam at the floor, a first beam at the window top lintel, and a second beam at the window sill.

[0029] The floor has a long-span, narrow and long shape, the aspect ratio is Lx/Ly>1.5, Ly≥34m, the floor’s Lx=m×b, Ly=n×2h.

[0030] The span side supports of the slab are set at the bisecting point every 2h of the span side, the long side supports are set at the alternately arranged points from the left and right ends to the center at intervals of b and 2b, and the columns are set on the honeycomb hollow sandwich panel The position of the floor support, the angle between the honeycomb grid hollow beam of the floor and the support side is 60°.

[0031] Example 2

[0032] Such as figure 2 As shown, when the honeycomb grid side length b=2m and the honeycomb grid height 2h=2×bsin60°=2×1.732m=3.464m, the floor Lx=m×b=2×(5×3b)+ b=31b=62m, Ly=n×2h=12×2×1.732m=41.568m, the floor area is about 2577m 2. The number of supports=2×5×2×2+2×11+4=66, and the number of columns is also 66.

[0033] Example 3

[0034] When the honeycomb grid side length b=2m, the honeycomb grid height 2h=2×1.732m=3.464m, m=31, n=10, the floor Lx=m×b=2×(5×3b)+ b=31b=62m, Ly=n×2h=10×2×1.732m=34.64m, the floor area is about 2148m 2. The number of supports=2×5×2×2+2×9+4=62, and the number of columns is also 62.

[0035] The ratio of the long side (Lx) to the span side (Ly), Lx/Ly=1.5~2, if the span Ly=36m, the long side Lx=54~72m, and the building area of ​​each floor is 1944m 2 ~2592m 2 between.
