Detailed Description
The present invention will be described in detail with reference to the accompanying drawings:
as shown in fig. 1-5: the novel multilayer logistics warehouse structure for the areas with medium and high intensity comprises a frame structure 1 and a plurality of K-shaped reinforcing units 2 connected to the frame structure 1;
the frame structure 1 comprises a plurality of frame columns 1-1 and a plurality of frame beams 1-2, the frame columns 1-1 are distributed and fixed in a rectangular array, adjacent frame columns 1-1 in any row or column are connected through the frame beams 1-2, the frame beams 1-2 are arranged at the elevation of a floor, and the frame columns 1-1 and the frame beams 1-2 are rigidly connected at nodes;
the K-shaped reinforcing unit comprises a horizontal rod 2-1 and a V-shaped inclined strut 2-2; the horizontal rod 2-1 is positioned below the frame beam 1-2, and the distance from the two ends of the horizontal rod 2-1 to the two ends of the frame beam 1-2 is not less than 1/3 of the height of the floor where the horizontal rod 2-1 is positioned; two ends of the horizontal rod 2-1 are rigidly connected with the frame column 1-1; the lower ends of the V-shaped inclined struts 2-2 are converged and fixed in the middle of the horizontal rod 2-1, and the two ends of the upper parts of the V-shaped inclined struts 2-2 are converged and fixed with the nodes of the frame columns 1-1 and the frame beams 1-2;
the K-shaped reinforcement unit 2 is arranged at the periphery of the fire compartment in the frame structure 1. According to the distribution mode of the K-type reinforcement unit 2 in the fire-protection subarea, the following two embodiments can be divided:
example 1
The K-shaped reinforcement units 2 are arranged continuously in the fire compartment (see fig. 3).
Example 2
The K-shaped reinforcing units 2 are arranged at intervals in the fire-proof subarea. The arrangement of the spaces can be divided into a plurality of cases.
In the fire-protection partition, there may be an area where the K-type reinforcing elements are not distributed between two K-type reinforcing elements (see fig. 4).
Or an area without K-type reinforcing units between the two groups of K-type reinforcing units; the number of each group of K-shaped reinforcing units in the two groups of K-shaped reinforcing units is two, and the corresponding region without the K-shaped reinforcing units is two spans (see fig. 8, 11 and 14).
The K-shaped reinforcing units 2 are made of reinforced concrete, so that the K-shaped reinforcing units and the frame structure 1 can be synchronously poured or prefabricated and assembled;
of course, the material of the K-shaped reinforcing unit 2 is a metal material; and after the frame structure 1 is built, the integral hoisting is combined with the frame structure 1. The V-shaped inclined strut 2-2 is made of high-ductility materials, and the V-shaped inclined strut 2-2 is used as an energy dissipation component to improve the ductility of the main body bearing structure under medium and large earthquakes. The metal material mainly refers to steel, aluminum profile and the like, and the high-ductility material can be a buckling restrained brace and the like.
In order to explain the performance of the utility model, the utility model arranges the following three schemes according to the type of the frame structure,
wherein, scheme A is a conventional frame structure (as shown in figures 6, 9 and 12); the scheme B is a frame structure with K-shaped reinforcing units continuously distributed (as shown in figures 7, 10 and 13); the scheme C is a frame structure in which K-type reinforcing units are arranged at intervals (see fig. 8, 11 and 14), and it should be noted that the interval arrangement in the scheme C is the second structure mentioned in example 2.
For comparison, 3 building structures with identical geometric dimensions and loading conditions in the above three schemes are calculated at the same time. The calculation result shows that the maximum vertex displacement of the scheme B is only 17% of that of the scheme A, the maximum vertex displacement of the scheme C is only 26% of that of the scheme A, and the K-type reinforcing unit 2 has a remarkable reinforcing effect. Under the same deformation requirement, the section size of the beam column of the frame structure can be reduced while the K-shaped reinforcing unit 2 is added.
In addition, the addition of the K-shaped reinforcing unit 2 enables the bending moment distribution of the structure to be more uniform, and the bending moment at the node is obviously reduced. A large amount of deformation energy is absorbed by the K-shaped reinforcing unit 2 in an axial stress mode, and the overall performance of the structure under medium and large earthquakes can be guaranteed.
