Abstract
The utility model discloses a slip-form support bar connector applied to supporting of coal mine underground roadways. The principle of bolt connection is utilized to facilitate connection of the steel tubular support bars, thereby increasing the construction efficiency. The slip-form support bar connector comprises a steel tubular support bar I and a steel tubular support bar II, the connection-required end portions of the steel tubular support bar I and the steel tubular support bar II are respectively provided with a hole (3), a bolt cap (1) and a bolt shank (2) which are respectively welded on the steel tubular support bar I and the steel tubular support bar II through the holes (3). The finished bolt and the bolt cap are welded respectively in the two steel tubular support bars in the utility model, and the bolt is tightened by using a pipe wrench to clamp the two steel tubular support bars in connection, thereby the slip-form support bar connector is convenient, speedy and labor-saving, and facilitates standardized construction.
Description
Technical field
The utility model relates to and is applied under the coal mine a kind of sliding formwork support bar joint in the roadway support operation.
Background technology
In the sliding shuttering construction technology that roadway support is operated under coal mine, steel pipe support bar joint generally adopts welding point or interpolation steel pipe joggle, these two kinds of technology job site welding job amounts are big, and jack needs the special messenger to nurse during by joint, prevents that top steel pipe support bar from coming off.
Summary of the invention
The utility model provides a kind of sliding formwork support bar joint, utilizes the Bolt Connection principle, and it is convenient that support bar is connected, and improves efficiency of construction.
In order to achieve the above object, the utility model adopts following technical scheme: include steel pipe support bar I and steel pipe support bar II, the end that need connect at steel pipe support bar I and steel pipe support bar II is respectively equipped with the hole, and nuts and shank of bolt are connected on steel pipe support bar I and the steel pipe support bar II by eyelet welding respectively.
The utility model is difference welding finished product bolt, nut in two steel pipe support bars, clamps two steel pipe support bars with pipe wrench during connection bolt is tightened, and is convenient and swift, saved manpower, is convenient to standardized construction.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in detail:
As shown be an embodiment of the present utility model, in steel pipe support bar I and the close mutually both ends perforate 3 respectively of steel pipe support bar II, nuts 1 is welded on the steel pipe support bar I by hole 3, shank of bolt 2 is welded on the steel pipe support bar II by hole 3, clamp two steel pipe support bars with pipe wrench respectively during use, shank of bolt 2 is screwed into nuts 1, tightens, two steel pipe support bars are connected as a single entity.
