Description

Technical Field

[0001] The utility model relates to the technical field of building demolition, in particular to a supporting frame for building demolition. Background Art

[0002] The building demolition methods are divided into mechanical demolition, blasting demolition and support frame demolition. Among them, the support frame demolition mainly adopts the manual demolition method, which is operated by workers and has the characteristics of high flexibility and wide application range. After the support frame is installed on the side of the building demolition, the staff will remove the load-bearing columns in sequence, and the stress point of the building will tilt to one side, so that the demolished building will be subjected to unilateral stress after contacting the support frame, so that the support frame will break or even overturn. In view of this, a support frame for building demolition is proposed. Utility Model Content

[0003] In order to solve at least one of the above-mentioned technical shortcomings, the utility model provides a support frame for building demolition, including a bottom frame, to which a plug rod is connected, a side convex plate is inserted on one side of the plug rod, and a pressure relief plate is arranged on the side convex plate, and a top frame is arranged above the connecting column.

[0004] Furthermore, a protruding upper convex plate is provided above the pressure reducing plate, a side plug hole is provided on the other side of the upper convex plate, a rod hole is provided in the middle of the pressure reducing plate, a rectangular groove is provided in the middle of the side convex plate, a connecting shaft is provided in the rectangular groove, and the connecting shaft is plugged into the side plug hole.

[0005] Furthermore, a top spring is arranged on the inner side of the bottom frame, and an output end of the top spring is connected to one side of the bottom of the pressure reducing plate.

[0006] Furthermore, the included angle between the top spring and the pressure reducing plate is 60°.

[0007] Furthermore, through holes with threaded threads are arranged on the four corners of the bottom frame, and the through holes are threadedly connected to the insertion rods. There are four insertion rods, and matching external insertion columns are arranged on the outer sides of the two insertion rods.

[0008] Furthermore, discs are provided at the top and bottom of the external plug-in column, and the top frame fits the disc at the top of the external plug-in column, and a fixed disc for limiting the position is also provided at the top of the plug-in rod.

[0009] Beneficial effect: the bottom frame is set next to the building that needs to be demolished, and the load-bearing columns of the building close to the side of the pressure relief plate are demolished. The center of gravity of the building tilts to one side and then contacts the upper convex plate above the pressure relief plate. The upper convex plate begins to rotate on the connecting shaft under the center force of the building, and the pressure relief plate rotates upward, driving the top spring on the inner side of the bottom frame outward, so that the tilting force on the upper convex plate is shared by the top spring, and at the same time, the ground rod connected to the rod hole on the other side of the upper convex plate is plugged into the ground to further share the center of gravity on the pressure relief plate to prevent the support frame from tipping over.
