Abstract
The utility model provides a ladder type column which is composed of at least two ladder type blocks and a screw bolt sleeve, wherein slots are arranged on the inclined plane of the upper and the lower ladder type blocks in a direction from an upper bottom to a lower bottom, and the screw bolt sleeves are arranged in slots contiguous to the upper and the lower ladder type blocks. The incipient and terminational supporting force strength of the column is strong, the structure is stable and safe, the manufacture is simple, the cost is low, and the ladder type column can be recovered and be repeatedly used. The installation and operation of the ladder type column are convenient, the utility model is suitable for supporting and protecting a mine, and can be widely used for supporting and protecting engineering, such as buildings, bridges, tunnels, etc.
Description
Technical field
The utility model relates to a kind of Ladder type column.
Background technology
The roadway support system of no ore pillar adopts shape to make organ timbering or the frame case is built into pack wall by laying bricks or stones with the accelerated cement mortar.Since pack wall just, whole support degree is little, is difficult to bear the power of adopting from powerful pressure of top board and ore body, it is badly damaged that supporting frame and tunnel are caused, its maintenance capacity is big, and increases many hidden dangers, influence normal operation, difficult popularization.
The supporting system of stoping operation face adopts round log or metal or heavy hydraulic pillar.The round log column strength is little, and waste is big.Metal or heavy hydraulic pillar body weight are difficult to use to high dipping ore bed, and the cost height.
Summary of the invention
The purpose of this utility model is the problem that exists at the support technology of the tunnel pillar of above-mentioned no ore pillar and stoping operation face, provide a kind of just, whole support degree is strong, structure is firm, high safety can reclaim and reusable Ladder type column.
Ladder type column of the present utility model is combined by at least two upper and lower adjacent trapezoid blocks and screw rod cover.The inclined-plane of upper and lower trapezoid block is respectively arranged with groove by upper base to the direction of going to the bottom, and is provided with the screw rod cover in the adjacent trenches between the upper and lower trapezoid block.
Ladder type column of the present utility model is first, whole support degree is strong, and structure is firm, and is safe and reliable, easily makes, and cost is low, can reclaim and reuse.Its installation, easy to use is not only applicable to mine support, can also be widely used in the supporting of engineerings such as building, bridge, tunnel.
Description of drawings
Fig. 1 is the elevational view of the utility model Ladder type column;
Fig. 2 is the facade view of Fig. 1.
The specific embodiment
Below in conjunction with above-mentioned accompanying drawing example Ladder type column of the present utility model is described in further detail.
The example of Ladder type column of the present utility model comprises upper trapezoid piece 1, screw rod cover 2, lower trapezoid piece 3, groove 4.Upper trapezoid piece 1 is respectively arranged with groove 4 with the inclined-plane of lower trapezoid piece 3 by upper base to the direction of going to the bottom, upper trapezoid piece 1, lower trapezoid piece 3 are right-angled trapezium, its upper base is the square of 0.4m * 0.4m, going to the bottom is the rectangle of 0.6m * 0.4m, and the length of the Ladder type column after the assembling * wide * height is the cuboid of 1m * 0.4m * 1m.Be provided with screw rod cover 2 between upper trapezoid piece 1 and the lower trapezoid piece 3 in the adjacent grooves 4, screw rod cover 2 is made of screw rod, baffle plate, nut, packing ring.
When Ladder type column of the present utility model is assembled, upper trapezoid piece 1, lower trapezoid piece 3 are put in supporting place accordingly, again assembling is prepended to the nut turn in the direction of the clock on the screw rod cover 2 in the groove 4, under the ramp effect of upper trapezoid piece 1, lower trapezoid piece 3, ore body roof can be withstood.When Ladder type column of the present utility model is reclaimed in the need dismounting, the nut on the screw rod cover 2 by turn counterclockwise, is imposed on certain external force again, under the ramp effect of upper trapezoid piece 1, lower trapezoid piece 3, its reduced height can unload.
Claims (1)
1, a kind of Ladder type column that is provided with two trapezoid blocks compositions at least, the inclined-plane that it is characterized in that upper trapezoid piece (1), lower trapezoid piece (3) is respectively arranged with groove (4) by upper base to the direction of going to the bottom, and is provided with screw rod cover (2) in the adjacent grooves (4) between upper trapezoid piece (1) and the lower trapezoid piece (3).
