Technical Field

The utility model relates to the technical field of building construction, in particular to a diagonal bracing structure of a staircase frame.

Background Art

The stair frame refers to a frame structure built at the same time as the stairs, which plays a load-bearing and fixing role, making the stairs stable and safe. The stair frame is generally composed of beams, columns, plates, etc., among which the beam bears the main weight and load, and is also the key component of the stair load-bearing. It supports the stair surface and handrails, and bears the weight of people and the impact force when walking on the stairs. When processing the stairs, a diagonal brace structure is required to provide auxiliary support for the stair frame.

In the prior art, the Chinese patent stair inclined board support structure with announcement number CN212671187U adopts the scheme of "including a first top stopper, a second top stopper and a movable groove; the first top stopper presses against the bottom surface of the stair inclined board to lift the stair inclined board; the inclined surface of the second top stopper presses against the side of the first top stopper facing away from the stair inclined board; the second top stopper is placed in the movable groove, the second top stopper moves in the movable groove in a direction close to the stair inclined board, the second top stopper tightly presses against the first top stopper, the first top stopper tightly presses against the stair inclined board; the bottom surface of the movable groove is fixedly connected to a support column", which is used to support the stair inclined board to a certain height. The application of this technical scheme can realize the simple operation of supporting the stair inclined board.

As shown in Figures 1-5, the embodiment of the utility model provides a diagonal bracing structure of a staircase frame, including a base 1, a plurality of hydraulic cylinders 2 are fixedly connected to the top of the base 1, a mounting plate 3 is fixedly connected to the output ends of the plurality of hydraulic cylinders 2, a mounting frame 4 is fixedly connected to the top of the mounting plate 3, a support plate 5 is rotatably matched with the top of the mounting frame 4, a plurality of mounting grooves 6 are opened on the top of the support plate 5, a damper 7 is installed at the bottom of the inner wall of the mounting groove 6, a compression spring 8 is sleeved on the damper 7, and a top plate 9 is fixedly connected to the output ends of the plurality of dampers 7;

A strip groove 10 is provided at the top of the mounting plate 3, and a driving mechanism 11 is arranged inside the strip groove 10. The driving mechanism 11 includes an adjusting screw 111 rotatably engaged with one side of the inner wall of the strip groove 10, a driving block 112 threadedly engaged with the adjusting screw 111, a knob 113 fixedly connected to the other end of the adjusting screw 111, and a movable plate 114 installed between the driving block 112 and the support plate 5.

The two ends of the compression spring 8 are fixedly connected to the top plate 9 and the mounting groove 6 respectively, and the top of the top plate 9 is fixedly connected with a rubber pad 12 .

The compression spring 8 is mainly used to increase the connection effect between the top plate 9 and the stair frame, thereby increasing the supporting effect on the stair frame. The rubber pad 12 can increase the friction between the top plate 9 and the stair frame to prevent sliding.

The knob 113 is located on one side of the mounting plate 3 , and two ends of the movable plate 114 are rotatably matched with the driving block 112 and the supporting plate 5 , respectively.

By turning the knob 113, the staff can drive the adjusting screw 111 to rotate, thereby driving the driving block 112. Under the transmission of the movable plate 114, the support plate 5 can be rotated on the mounting frame 4, so that the angle of the top plate 9 is rotated, which is convenient for supporting the stair frame.

A storage groove 13 is provided at the bottom of the base 1, and a threaded rod 14 is rotatably engaged with the upper side of the inner wall of the storage groove 13, and a driving plate 15 is threadedly engaged with the threaded rod 14. The bottom of the driving plate 15 is fixedly connected to two connecting plates 16, and the bottom of the two connecting plates 16 is fixedly connected to an anti-skid plate 17, and the bottom of the anti-skid plate 17 is fixedly connected to an anti-slip pad 18.

The staff rotates the threaded rod 14 to drive the driving plate 15 to move, and under the connection of the connecting plate 16, drives the anti-skid plate 17 to move downward. When the anti-skid plate 17 moves downward and contacts the ground, the anti-skid pad 18 provided at the bottom of the anti-skid plate 17 prevents the equipment from sliding during use, thereby improving the supporting effect on the stair frame.

A turntable 19 is fixedly connected to the upper end of the threaded rod 14 , and the turntable 19 is located above the base 1 .

The setting of the turntable 19 is mainly used to drive the threaded rod 14 to improve the convenience of using the equipment.

Two limit rods 20 are fixedly connected to the upper side of the inner wall of the storage groove 13 , and the two limit rods 20 are slidably matched with the driving plate 15 .

The setting of the limiting rod 20 can limit the movement of the driving plate 15 when the rotating turntable 19 drives the threaded rod 14 to rotate, thereby preventing the driving plate 15 from rotating and increasing the stability of the movement of the driving plate 15.

A plurality of universal wheels 21 are fixedly connected to the bottom of the base 1 , a fixing plate 22 is mounted on one side of the base 1 , and a handle 23 is fixedly mounted on one side of the fixing plate 22 .

The arrangement of the universal wheels 21 makes the device easy to move, and the combination of the fixing plate 22 and the handle 23 makes it easy for the staff to control the device, thereby increasing the comfort of use.

When the diagonal bracing structure of a staircase frame of the utility model is used, the handle 23 is held by hand, and the device is moved under the action of the bottom universal wheel 21 under the transmission of the fixed plate 22. When the device moves to the desired position, the turntable 19 is rotated, and the rotation of the turntable 19 drives the threaded rod 14 to rotate, and the rotation of the threaded rod 14 drives the driving plate 15 to move. The driving plate 15 moves under the connection of the connecting plate 16, so that the anti-skid plate 17 moves downward and contacts the ground. When the anti-skid plate 17 contacts the ground, the stability of the device is increased;

Turn the knob 113, and the knob 113 drives the adjusting screw 111 to rotate. The adjusting screw 111 rotates to make the driving block 112 slide in the strip groove 10. The movement of the driving block 112 is driven by the movable plate 114, so that the support plate 5 rotates on the mounting frame 4, so that the angle of the support plate 5 is consistent with the inclination angle between the stair frames. Under the action of the hydraulic cylinder 2, the mounting plate 3 drives the support plate 5 to move upward. When the top plate 9 contacts the stair frame, it continues to apply pressure upward, so that the top plate 9 is forced to squeeze the damper 7, so that the compression spring 8 on the outside of the damper 7 is forced to shrink. Under the reaction of the compression spring 8, the top plate 9 and the stair frame are more closely fitted, thereby improving the supporting effect on the stair frame.

The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model.
