Detailed Description
The present invention will be further explained with reference to the accompanying drawings.
The utility model provides a construction elevator instrument formula safety device, includes scaffold frame and a plurality of protection network, the protection network includes the frame 1 of rectangle, is equipped with two criss-cross bracing 2 in the frame 1, and the both ends of bracing 2 are connected with the apex angle of frame 1 respectively, and the surface of frame 1 is equipped with steel mesh piece 3, and one side of the steel pipe 4 of scaffold frame is equipped with connecting rod 5, and the one end and the scaffold connection of connecting rod 5, the other end are equipped with H shaped steel 6, are connected with the one end of protection network respectively in two upper and lower recesses of H shaped steel 6.
The protective net comprises a middle protective net positioned between elevator doors of the elevator, side protective nets positioned on two sides of the elevator doors and an upper protective net positioned above the elevator doors.
The thickness of the steel mesh 3 is 3 mm.
The aperture of the steel mesh 3 is 5 mm.
And a steel wire with a fixing function is arranged between the protective net and the scaffold.
The method comprises the steps of firstly welding square pipes of 30 x 3mm into square pipes of a square shape with a mouth and a middle diagonal brace to form a frame, welding a steel mesh piece with the thickness of 3mm and the aperture of 5mm with the square pipe frame, fixing an H-shaped steel connecting piece at the corresponding position of a steel pipe scaffold, and finally firmly fixing the whole tool type safety protection mesh piece with the steel pipe scaffold (the safety protection mesh piece is divided into three specifications of the upper part, the middle part and the side surface of an elevator door opening).
The method comprises the following specific steps:
firstly, welding square tubes into a square shape, and performing cross welding on the square tubes inside the square tubes to form a frame;
and then the steel mesh sheet and the square tube frame are welded (the blanking size of the square tube and the steel mesh sheet body is based on the size of the on-site construction elevator protection frame), so that a safety protection mesh sheet is formed.
Before the net sheets are installed, short steel pipes are welded on a scaffold body of a construction elevator scaffold, one end of each short steel pipe is fixed with the scaffold body, H-shaped steel is welded at the end part of the other end of each short steel pipe, an upper safety protection net and a lower safety protection net are embedded into grooves of the H-shaped steel, and the H-shaped steel is used as supporting points and separating points of each safety net, so that the safety protection nets are effectively fixed;
and the 22# iron wire is used for firmly binding the protective net sheets with the steel pipe scaffold body, the installation sequence is sequentially carried out from bottom to top, and the synchronization with the engineering is kept. The construction elevator is installed according to the sizes of the construction elevator outer frame and the opening of the elevator, the installation sequence is consistent with the erection sequence of the construction elevator scaffold body from low to high, the construction elevator is installed according to the specific size of the steel pipe scaffold body in a slicing mode, and except that the positions of two construction elevator doors are not installed, other positions are all installed (the front and the side of the scaffold are installed).
Before the installation of the net sheets, the H-shaped steel connecting pieces are fixed at corresponding positions on the outer protective frame of the construction elevator. H-shaped steel connecting pieces are arranged on the upper portion, the lower portion and the two sides of the construction elevator door opening and used for fixing the safety net piece and the construction elevator door frame. A connecting piece (a connecting piece formed by welding H-shaped steel and a short steel pipe) is arranged between every two pieces of safety protection nets and is fixed on the outer protection steel pipe scaffold to form a whole with the scaffold body.
During installation, the safety protection net piece is installed from bottom to top and is divided into a front safety protection net piece and a side safety protection net piece, wherein the front safety protection net piece is divided into a middle net piece (a middle safety protection net is arranged between two construction elevator doors), side net pieces (side net pieces are arranged on two sides of the construction elevator doors) and an upper net piece (an upper safety protection net piece is arranged on the upper portion of the construction elevator doors). Utilize 22# iron wire firmly with safety protection net and steel pipe scaffold ligature, and every safety protection ligature fixed point is no less than 5 (four angles and central point all will ligature one).
When the construction elevator is dismantled, the construction elevator is dismantled according to the principle of 'taking before dismantling, taking after dismantling before dismantling, from top to bottom', so that the safety protection net is dismantled before the platform and the steel pipe scaffold are dismantled, the platform and the steel pipe scaffold are dismantled layer by layer in sequence, and the platform and the steel pipe scaffold are stacked orderly according to specification and size so as to be convenient to transport to other projects for use.
