Description

High-stability hollow column

Technical Field

The invention relates to the technical field of house bearing, in particular to a high-stability hollow column.

Background

In the building construction, solid post is commonly used, for example reinforced concrete post, but discover in the use that many times solid reinforced concrete post satisfies the required intensity requirement of structure far away, and the dead weight of reinforced concrete solid post is also great, gives the very big load of floor, discovers afterwards that hollow post also can satisfy the design requirement in the construction to owing to be hollow structure, the dead weight is less, and economy is pleasing to the eye, save material, therefore hollow post is the inevitable trend of development now. At present, the most common hollow column body is generally a metal or nonmetal welded pipe, a seamless pipe, a special-shaped section bar and a rotary pressing formed column body, but the hollow column body has the same defects that the hollow column body with a complex appearance cannot be realized, special equipment and a mould are needed, only an open hollow column body can be realized, and the axial direction cannot be strengthened. The hollow column knuckle boards on the market can only be spliced to be long and cannot be widened, and are horizontally spliced in the width direction, so that the stability is poor and lateral bending is easy to occur.

The Suli seeks to provide a design method of a hollow column in 'a hollow column' CN107460996A patent, the hollow column comprises a male groove and a female groove, square bumps are arranged at two ends of the male groove, a groove corresponding to the bump is arranged at one end of the female groove, a transverse flow tooth is arranged at one end of the female groove, and the square bumps of the male groove and the groove corresponding to the female groove are connected in a matched mode to form a whole, so that the hollow column is prevented from moving up and down in a staggered mode, and the stability of the column is improved. However, under the action of a large external force load, the joint of the male groove and the female groove is easy to deform and even break, and the stability of the structure is reduced. When the slenderness ratio of the hollow column is very large, the hollow column can be laterally bent under the action of external force, and the hollow column is easy to be unstably damaged. The female grooves are formed by splicing the transverse flow teeth, and the hollow column is lack of integrity, so the hollow column has defects in design. This is also a common problem with current hollow columns.

The inside equidistant three horizontal partition that sets up of hollow post of high stability, wherein both ends respectively set up a horizontal partition about the post, the centre position sets up a horizontal partition, horizontal partition thickness is the same with flute profile plank thickness, it is fixed with horizontal partition and flute profile billet with the pin, its effect is in order to improve the anti lateral deformation ability of hollow post, when the length and fineness ratio of hollow post is too big, can make hollow post produce the amount of deflection under the external load effect, the unstability condition appears even, at the inside equidistant three horizontal partition that sets up of hollow post of high stability, can increase the lateral rigidity of hollow post, resist the lateral deformation that causes under the external load effect. The length of the pin is greater than the thickness of the groove-shaped wood block, the pin is arranged at the joint of the groove-shaped wood block and the transverse partition, the groove-shaped wood block and the transverse partition are fixed, and the pin has the advantages that the structure of the pin is provided with the circular protective wall, so that creep deformation generated by the groove-shaped wood block of the hollow column under the long-term loading effect has little influence on the pin, the pin cannot be loosened, the groove-shaped wood block and the transverse partition can be fixed well, the stability of the hollow column cannot be reduced, the deformation resistance of the hollow column is improved, the length of the pin is greater than the thickness of the groove-shaped wood block, the pin is too short, the anchoring capacity of the pin can be greatly reduced under the long-term loading effect, and even the pin falls off, so that the length of the pin is greater than the thickness of the groove-shaped wood block, and the transverse partition and the groove-shaped wood block are fixed into a whole.

After adopting above-mentioned structure, four trough-shaped wood pieces are the same, and production is convenient, but assembly line batch production, and quality is easy to control and with low costs, and trough-shaped wood piece meshes the concatenation through square lug and corresponding recess between each other, so can not take place the dislocation from top to bottom between the trough-shaped wood piece. The inside equidistant three horizontal partitions that set up of hollow post of high stability can increase the lateral rigidity of hollow post, can resist lateral deformation under the exogenic load effect, prevents that unstability from appearing in hollow post from destroying. The pins are arranged at the splicing position and the transverse partition position of the groove-shaped wood block, so that the in-plane shearing deformation of the hollow column can be prevented. The length of the pin is larger than the thickness of the groove-shaped wood block, so that the hollow column can be prevented from being damaged due to falling of the pin.

In addition, the hollow column has a simple structure, can enhance the stability of the hollow column, can save materials, is energy-saving and environment-friendly due to the hollow structure, is provided with the pin at the joint of the groove-shaped wood blocks, and has a round protective wall due to the structure of the pin, so that the creep deformation generated by the groove-shaped wood blocks of the hollow column under the long-term load action has little influence on the pin, the pin cannot be loosened, the groove-shaped wood blocks and the transverse partition plate can be well fixed, the stability of the hollow column cannot be reduced, and the deformation resistance of the hollow column is enhanced.
