Detailed Description

In order to make the technical solutions of the present invention better understood, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention.

As shown in fig. 1 to 5, a hollow core panel according to the invention, which is intended for the furniture industry, comprises a closed frame 1, a cover plate 2 at the top of the frame 1 and a bottom plate 3 at the bottom of the frame 1, wherein a support plate 4 divides the frame 1 into a plurality of reinforcement areas 5 for placing reinforcement units 6, the size of the reinforcement areas 5 being such that the actual size of the furniture can be adjusted, and in principle the larger the size of the furniture, the smaller the area of the reinforcement areas 5; the smaller the size of the furniture, the larger the area of the reinforcing area 5, the more the reinforcing unit 6 comprises a plurality of groups of reinforcing columns 61 uniformly distributed in the reinforcing area 5, and gaps 67 exist between each group of reinforcing columns 61, preferably, the spacing between the reinforcing columns 61 is 0.1-0.3 cm; preferably, at most three sets of reinforcement columns 61 are provided in each reinforcement area 5, and preferably, two sets of reinforcement columns 61 are provided in the reinforcement area 5. Since the plurality of reinforcing columns 61 having a gap are provided in the reinforcing region 5, the plurality of reinforcing columns 61 have a certain movement space in the longitudinal direction of the hollow plate.

The reinforcing columns 61 comprise reinforcing blocks 62 which are parallel to each other and the adjacent reinforcing blocks 62 are connected with each other, each reinforcing block 62 comprises a first reinforcing plate 63 and a second reinforcing plate 64 which are symmetrically arranged, two ends of each first reinforcing plate 63 are connected with two ends of each second reinforcing plate 64, the middle parts of the first reinforcing plates 63 and the middle parts of the second reinforcing plates 64 are bent outwards to form a hollow groove 66, partition plates 661 which are respectively abutted against the first reinforcing plates 63 and the second reinforcing plates 64 are arranged on the hollow grooves 66, and preferably, the partition plates 661 have elasticity. Since the partition 661 has elasticity, the plurality of reinforcing rows 61 also have a certain space in the width direction of the hollow board.

Specifically, the reinforcing columns 61 have a certain movement space in the reinforcing area 5 in both the length direction and the width direction of the hollow slab, and the movement space is embodied in such a way that when the hollow slab is installed and used, the reinforcing columns 61 can be adjusted according to the actual stress point of the hollow slab. In the daily use process of the furniture, the weight to be born by the plate is different according to the weight of the placed object or the position of the placed object, for example, one object is placed in the center of the hollow plate, the acting point of the object is in the middle of the hollow plate, and the acting points of the hollow plate are distributed around the hollow plate; for example, an article is placed on the left side of the hollow slab, the force point of the article is on the left side of the hollow slab, and the force points of the hollow slab are not uniformly distributed on the hollow slab, that is, the left side of the hollow slab close to the article is more stressed than the right side of the hollow slab, so that the left side of the hollow slab needs to be reinforced; for example, an article is placed on the right side of the hollow board, the force point of the article is on the right side of the hollow board, and the force points of the hollow board are not uniformly distributed on the hollow board, that is, the right side of the hollow board close to the article is more stressed than the left side of the hollow board, so that the right side of the hollow board needs to be reinforced; for example, two articles with different weights are placed on the left side and the right side of the hollow slab, the weight of the article on the left side is larger than that of the article on the right side, the acting point of the hollow slab is on the left side and the acting point of the hollow slab is on the left side, the pressure of the article on the hollow slab on the left side is larger than that of the article on the hollow slab on the right side, and at the moment, three stress points on the hollow slab are respectively the position where the left side of the hollow slab is close to the article, the position where the right side of the hollow slab is close to the article, and. In summary, in the use of daily furniture, the stress points of the hollow slab are not uniform due to various reasons such as the position of placing articles, the weight of placing articles, the way of placing articles and the like, or the stress points of the hollow slab are different or changed due to different times of placing articles, different habits of people placing articles and the like; however, since the reinforcing columns 61 in the hollow board have a certain space for movement in both the longitudinal direction and the width direction of the hollow board, the relative positions of the reinforcing units 6 can be changed, and therefore the reinforcing units 6 can also move relative to the reinforcing portion of the hollow board.

In order to verify the strength of the hollow core slabs of the present invention, the following were analyzed in comparison with comparative examples: comparative example 1: patent numbers: 201820820777.6 application date: 2018-05-28, patent name: a hollow core panel; comparative example 2: commercially available hollow core slabs; comparative example 3: a certain three-ply board purchased in the market; comparative example 4: a certain solid wood board purchased in the market; and the surface areas of the five types of plates are the same.
