Abstract
The utility model discloses a coal mine underground convenient-installation steel bar mesh for supporting and relates to the field of coal mine underground supporting devices. The coal mine underground convenient-installation steel bar mesh for supporting is applied to solve such problems as labor and time wasting of the current coal mine underground steel bar mesh for supporting during installation, etc. The coal mine underground convenient-installation steel bar mesh for supporting is provided with longitudinal steel bars and horizontal steel bars; the number of the longitudinal steel bars is equal to the number of the horizontal steel bars; moreover, the longitudinal steel bars and the horizontal steel bars are vertically welded in equal distances; the end pats of the longitudinal steel bars at the same side are provided with hooks with the same direction; and the distance from the top part of the hook to the neighboring horizontal steel bar is equal to the distance between every two neighboring horizontal steel bars. The coal mine underground convenient-installation steel bar mesh for supporting has a simple structure and is convenient to install.
Description
Technical field
The utility model relates to a kind of supporting installation in underground mining of coal mine, particularly relates to the supporting of being convenient to install under a kind of coal mine and uses reinforced mesh.
Background technology
At present supporting mainly is the many orthogonal welding of reinforcing bar or with the be formed by connecting net structure of box-shaped of fixation with steel wire with reinforced mesh under the coal mine; But when running into the work plane that carries out supporting under the coal mine and be vertical or top then reinforced mesh need splice one by one and fix; Surpass the further beyond doubt labor intensity of operating personnel that increases under the atmospheric working environment at coal mine deep well, also have a strong impact on the manufacturing schedule under the coal mine on the other hand.
The utility model content
The purpose of the utility model is in order to overcome deficiency of the prior art, provides the supporting of being convenient to install under a kind of coal mine simple in structure and easy for installation to use reinforced mesh.
For realizing above-mentioned purpose, the utility model provides the supporting of being convenient to install under a kind of coal mine to be provided with longitudinal bar and cross reinforcement with reinforced mesh, and longitudinal bar equates with the radical of cross reinforcement and equidistant vertical welding mutually; The end of the same side of longitudinal bar is provided with the identical hook of direction, and the top of hook equals the distance between each adjacent cross reinforcement to the distance of adjacent cross reinforcement.
The radical of said longitudinal bar is 11, and the radical of said cross reinforcement is 11.
The utility model beneficial effect is: the supporting of being convenient to install under the coal mine of the utility model is end reinforced owing to being provided with hook with reinforced mesh one side; This makes to the coal mine gradient work plane mounting reinforcing steel bars net the sheet big or top that has a down dip very laborsaving; Directly be connected with a last reinforced mesh and need reinforced mesh do not fixed on mining face under mine with linking up with; Reduce labor intensity of operating personnel, also improved production efficiency under the coal mine.
Supporting below in conjunction with being convenient to install under the coal mine of accompanying drawing to the utility model is described further with reinforced mesh.
Description of drawings
Fig. 1 is embodiment one perspective view of the utility model;
Fig. 2 is embodiment two perspective view of the utility model.
Among the figure: 1, longitudinal bar, 2, cross reinforcement, 3, hook.
The specific embodiment
Embodiment one is as shown in Figure 1, and the supporting of being convenient to install under the coal mine of present embodiment is provided with longitudinal bar 1 and cross reinforcement 2 with reinforced mesh, and longitudinal bar 1 equates with the radical of cross reinforcement 2 and equidistant vertical welding mutually; The end of the same side of longitudinal bar 1 is provided with the identical hook of direction 3, and the top of hook 3 equals the distance of 2 of each adjacent cross reinforcements to the distance of adjacent cross reinforcement 2.The radical of longitudinal bar 1 is 11, and the radical of cross reinforcement 2 is 11.
Embodiment two is as shown in Figure 2; The supporting of being convenient to install under the coal mine of present embodiment is provided with hook 3 with 7 at the middle part in the longitudinal bar 1 of reinforced mesh; Two longitudinal bars 1 of each of both sides totally four hook is not set, the supporting of being convenient to install under the coal mine of present embodiment with other of reinforced mesh be provided with embodiment together.
Can be directly when coal mine has a down dip the work plane mounting reinforcing steel bars net sheet at the big or top of gradient with the hook on the reinforced mesh 3 with on cross reinforcement 2 on reinforced mesh articulate, realize fixing of reinforced mesh, time saving and energy saving.
Claims (2)
1. reinforced mesh is used in the supporting of being convenient to install under the coal mine, it is characterized in that the supporting of being convenient to install under the said coal mine is provided with longitudinal bar and cross reinforcement with reinforced mesh, and longitudinal bar equates with the radical of cross reinforcement and equidistant vertical welding mutually; The end of the same side of longitudinal bar is provided with the identical hook of direction, and the top of hook equals the distance between each adjacent cross reinforcement to the distance of adjacent cross reinforcement.
2. reinforced mesh is used in the supporting of being convenient to install under the coal mine according to claim 1, it is characterized in that, the radical of said longitudinal bar is 11, and the radical of said cross reinforcement is 11.
