The present invention relates to a kind of safety protection equipment used for surrounding a building or a site, and more specifically relates to a kind of fence column and a kind of fence system.
A fence system used for surrounding a building or a site is usually formed by connecting a fencing net and a fence column. A common fence column is shown for example in FIG. 1 of European granted patent EP1564351B1. This kind of fence column comprises a hollow post with a rectangular cross section, a cover plate covering one side of the hollow post and a tightening member for fixing the fencing net between the cover plate and the hollow post. The tightening member is fixed to the hollow post after passing through the cover plate and a hole on the fencing net. A fence system using this kind of structure is susceptible to damage because the fencing net is just loosely fixed due to only a few fixing points on which the fencing net is positioned, connected and fixed via the tightening member alone. In FIG. 2 of EP1564351B1, another fence column is disclosed. According to the disclosure, tightening members are used for positioning, connecting and fixing the fencing net to the post, but this kind of structure still cannot solve the problems of insufficient fixing points for the fencing net and susceptibility to damage. In some fence systems especially those requiring better defense against damage, anti-theft bolts are usually required, but anti-theft bolts are more expensive. Production cost of the fence system will also significantly increase if the quantity of the fixing points is increased by providing more tightening members.

2. Hook shaped protrusions are provided on the first positioning members or on the second positioning members so that the assembly of the cover plate and the column can resist and defend against disassembly and damage.
3. The fence column has an opening, thereby saving manufacturing material and at the same time saving welding procedure and lowering the production cost.
The present invention will be described further in detail below with reference to the accompanying drawings. In the present description, “front” refers to an upward pointing direction in
With reference to
Each of the fence columns 100 comprises a vertically extending first main body 110 and a second main body 120 fixedly connected with the first main body 110; a connecting surface 112 is provided on one side of the first main body 110 where the first main body 110 is connected with the second main body 120; the first main body 110 can have different structures, for example a vertically extending hollow post as shown in
If the first main body 110 is a hollow post, there can also be an opening at the perimeter of the first main body 110 as shown in
The second main body 120 can be a sheet like cover plate as shown in
The net 200 can be a welded mesh, a woven mesh, a rollable mesh, a Dutch wire mesh or a metal lath etc; alternatively, the net 200 can also be a panel, or a flat structure formed by combining multiple panel units, strip units or post units, or a flat structure formed by combining meshed metal and panel units, strip units or post units; preferably, the net 200 is a Dutch wire mesh.
As shown in
Preferably, the multiple first positioning members 114 are divided into two columns and each column of the first positioning members is arranged vertically on the connecting surface 112 of the first main body 110; the multiple second positioning members 121 are also divided into two columns and each column of the second positioning members 121 is arranged vertically on the second main body 120; a column of the first positioning members on the left side of the first main body and a corresponding column of the second positioning members on the second main body are used for positioning a net at the left side, another column of the first positioning members on the right side of the first main body and a corresponding column of the second positioning members on the second main body are used for positioning another net at the right side, as shown in
Preferably, the multiple first positioning members 114 are divided into two columns and arranged near to the edges of the connecting surface, and the multiple second positioning members 121 are divided into two columns and arranged near to the edges of the second main body 120; if the first main body 110 is a post having an opening, as shown in
In the present embodiment, the first positioning members 114 are holes, while the second positioning members 121 are protrusions; alternatively, the first positioning members 114 are protrusions and the second positioning members 121 are holes; meshes 201 are present on the net 200; when the second main body 120 is fixed to the first main body 110, the protrusions pass through the meshes of the net 200 and insert into the holes and are therefore fixed in position; in other embodiments, both the first positioning members and the second positioning members are hook shaped, when the first main body 110 is fixed with the second main body 120, the first positioning members and the second positioning members are hooked together; preferably, the first positioning members 114 are holes, and the second positioning members 121 are hook shaped protrusions; the hook shaped protrusions first extend horizontally along a direction perpendicular to the vertical direction from a side surface of the second main body 120, and then bend towards the vertical direction to form blocking portions which prevent the second main body 120 from separating from the first main body 110; the multiple second positioning members 121 bend upwardly or downwardly along the same direction; when the second positioning members 121 are inserted into the first positioning members 114, the second main body 120 can be hooked onto the first main body 110.
The ends of the hook shaped protrusions can also extend horizontally; the ends of the protrusions of one column of the second positioning members 121 extend leftward and the ends of the protrusions of another column of the second positioning members 121 extend rightward; the hook shaped protrusions can be formed by bending by means of a tool during the process of installation; during installation of the second main body 120, the second positioning members 121 not yet bent and deformed can first be inserted into the first positioning members 114, and then the two columns of second positioning members 121 are being bent to the left and right sides respectively at an inner side of the first main body 110 by means of a tool so that the second positioning members 121 can hook onto the first main body 110.
The fence columns are generally made of metal material which has a certain flexibility to deform; specifically, the first main body 110 and the second main body 120 may achieve flexible deformation by providing flexible deformable portions horizontally or vertically deformable. In the present embodiment, the base portion 111 of the first main body 110 has an opening; therefore when horizontal compression or tension force is applied to the base portion 111, the base portion 111 can be compressed or tensioned horizontally, thereby changing the linear distance between the two columns of first positioning members 114; the curved rib portion 124 provided on the second main body 120 can provide a certain extent of flexibility to the second main body 120; therefore installation tools can be used for flexible deformation of the first main body 110 to bring the two columns of first positioning members 114 close to each other during installation, and the second positioning members 121 are manipulated to pass through the two columns of first positioning members 114; after installation and removal of external force, the first main body 110 deforms to regain its original shape so that the two columns of second positioning members 121 are tensioned and inwardly hook on two sides of the connecting surface; the same principle applies to installation by deforming the second main body 120. In
The flexible deformation can occur horizontally or vertically. When the second main body is horizontally tensioned on the first main body, the second main body can be outwardly tensioned on the first main body or inwardly pressed on the first main body, whereas “outwardly” herein means the directions from the center of the opening of the first main body towards the left and right sides of the first main body with reference to
As shown in
Preferably, the first positioning members 114 are integrally formed on the connecting surface 112, and the second positioning members 121 are integrally formed on the second main body 120. The protrusions are formed by bending and stamping the connecting surface 112 or the second main body 120. There is no specific requirement concerning the sequential order of bending procedure and stamping procedure.
Preferably, the distance between any two meshes 201 adjacent to each other vertically on the net 200 is the same; the distance between any two first positioning members 114 vertically adjacent to each other or the distance between any two second positioning members 121 vertically adjacent to each other is multiple integer of the distance between any two meshes 201 vertically adjacent to each other, so as to ensure that the all the first positioning members or all the second positioning members can pass through the meshes 201.
Apart from the self-connection as mentioned above, the first main body 110 and the second main body 120 can also be fixed by welding, or connected via a tightening member 300.
As shown in
Alternatively as shown in
Specifically, one end of the tightening member 300 passes through an installation hole 122 on the second main body 120 and then fixes with the connecting surface 112 of the first main body 110, as shown in
