The utility model discloses a metal oil drum with a pressure-resistant structure, which comprises a drum body and an outer convex ring, the outer convex ring is arranged on the outer wall of the drum body, a drum top and a drum bottom are respectively and fixedly arranged on the top surface and the bottom surface of the drum body, a middle column is arranged in the drum body, a top plate and a bottom plate are welded on the top surface of the middle column, and the bottom plate is welded on the bottom surface of the middle column. The surface of the middle column is fixedly connected with inner ribs through supporting rods. The utility model has the beneficial effects that the middle column, the supporting rods and the inner ribs are integrated, the top surface and the bottom surface of the middle column are fixedly connected with the top plate and the bottom plate respectively to play a central supporting role and improve the vertical compression resistance of the barrel body, the middle column is fixedly connected with the inner ribs through the supporting rods, and the inner ribs abut against the inner wall of the barrel body to play a lateral supporting role, so that the vertical compression resistance of the barrel body is improved. The lateral pressure resistance of the barrel body is improved, the pressure resistance of the barrel body is improved in all directions, the use stability is improved, meanwhile, after the barrel body is scrapped, a worker can open the barrel top or the barrel bottom and take out the top plate, the bottom plate, the middle column and the inner ribs for repeated use, and material waste is reduced.

The utility model provides a size's table case support structure of adjustable, including middle column and the side column of setting in the both sides of middle column, be provided with the moving mechanism for the side of auxiliary side column to the side of moving away or close to middle column between middle column and side column, be provided with first moving plate on the middle column, there is moving device for the first moving plate of auxiliary first moving plate along the height direction of middle column moves between middle column and first moving plate, moving device includes the screw rod of fixing in one side of middle column and the nut of fixing in one side of first moving plate, screw rod passes through nut and is connected with the nut screw thread, the top fixed setting of screw rod has the rotation block of driving screw rod rotation, this table case support structure can accurately adjust the distance between side column and middle column, thereby improve the stability that support table case supports.

This utility model relates to the field of support and hanger technology, specifically a prefabricated support and hanger. It includes at least three vertically parallel support columns, each comprising two side columns on either side and several middle columns between the two side columns. Each side column has an inward-facing "L"-shaped connector detachably mounted on it, and each middle column has two outward-facing "L"-shaped connectors detachably mounted on it. The "L"-shaped connectors are vertically adjustable. A crossbeam is provided between each pair of adjacent support columns, resting between the two "L"-shaped connectors. The bottom of the crossbeam is fixedly connected to the "L"-shaped connectors by bolts. This structure distributes the supporting force of the crossbeam to the "L"-shaped connectors on both sides, effectively allowing the "L"-shaped connectors to support the crossbeam. This method is more stable, has a higher safety factor, and does not involve the interlocking of teeth, thus lowering installation requirements.

The application discloses a through-type anchor rod supporting system for a cow nose roadway and a supporting method thereof, and aims at the problem that a middle column wall in the cow nose roadway is discontinuous in stress and prone to local instability, the application proposes that a plurality of hollow grouting anchor rods are arranged horizontally and penetratingly along the thickness direction of the middle column wall, and the two ends of the anchor rods extend to the spaces of the two side roadways; a tray, a fastening nut and a connecting component interface are installed at the ends, and the ends of the upper and lower adjacent anchor rods are rigidly connected through long straight connecting rods to form a spatial truss type connecting network; and a grouting and reinforcing assembly is used for grouting into the hollow cavities of the anchor rods and the surrounding rock cracks to form a grouting and reinforcing area. Finally, the through-type grouting anchor rod, the spatial connecting assembly and the reinforced middle column wall jointly form a spatial closed whole cooperative bearing structure. The application changes the traditional point-like isolated anchoring into three-dimensional spatial net-like bearing, actively pre-tightens and transmits stress to deep surrounding rock, effectively inhibits early deformation and damage of the surrounding rock, is convenient to construct and is economical and practical.
