Description

Gangboard stand of scaffold and its dust-proof life net combined apparatus

The utility model relates to the scaffold of building.

Built a house in the past and all set up scaffold usually with bamboo or iron pipe, pedestal all be by vertical supporting rod, main beam bar, side crossbeam bar letter is tight or spiral shell forms the frame type pedestal admittedly, with the pedestal is that several rows of the installation from level to level in unit forms scaffold, on pedestal, place the rectangle pedal, pedal does not generally tighten up, what have also is that unidirectional upper shield fastens, thereby often cause crank when trampling, be skewed easily, though be erected with Air Filter in the scaffold outside, but Air Filter also just buckles with simple iron wire, and then Air Filter can't prevent accident effectively.This class scaffold is running into high wind when raining heavyly, waves easily and blows down, and pedal skids easily, when the workman constructs, cause unnecessary contingency easily, and building when construction, usually because of the difference that shares out the work, construction each floor face of being everlasting is constructed simultaneously, and often has between pedal and the pedestal than large space, so constructor's thing that drops because of carelessness often takes place upstairs, and make the lower floor constructor be subjected to unexpected injury, though what have is covered with bamboo raft, the rainy day also slips easily, and safety is relatively poor.This scaffold installation and dismounting are all inconvenient, insecure construction speed and the safety of influencing.

The purpose of this utility model is outside the deficiency at above scaffold, plan is improved on the basis of original scaffold and is perfect, a kind of scaffold running-board bracket and dustproof life net composite set thereof are provided, mainly be to be shaped on forwards, backwards on the perpendicular steel pipe or protruding cover button is prolonged in the interior outside supporting, be mounted to the frame type pedestal in order to socket main beam steel pipe and side crossbeam steel pipe, and between the perpendicular steel pipe of support, intertie is installed, with the pedestal is the several rows of socket installation mutually from level to level in unit, running-board bracket is packed on the side crossbeam steel pipe of pedestal, the life net of will preventing dust then one end cover Guan County is contained on the hook in the running-board bracket outside, other end cover Guan County is contained on the hook of the pedestal outside or intertie, or on the hook of main beam steel pipe, reaching scaffold installs, dismounting is quick, firmly, safety, can prevent during construction that construction material is (as stone, mince etc.), instrument drops and pounds and hurts sb.'s feelings, the constructor can not slip, and has improved safety.

Realization of the present utility model is a kind of scaffold running-board bracket of design and dustproof life net composite set thereof, and it is made up of pedestal, running-board bracket, dustproof life net.

The appropriate position is shaped on forwards, backwards or protruding cover button is prolonged in the interior outside on the perpendicular steel pipe of the support of pedestal, socket is equipped with main beam steel pipe, side crossbeam steel pipe respectively on the cover button, on the main beam steel pipe, be shaped on some hooks, can between the perpendicular steel pipe of support, intertie be installed, being shaped on hook in the intertie bottom, is that the unit makes the several rows of interlocking installation mutually from level to level of scaffold with this pedestal.

The rectangle running-board bracket is installed in the pedestal, be shaped on and the corresponding arc notch of side crossbeam steel pipe in the side, front and back end of running-board bracket, cooperate its side weldering to be shaped on ㄇ type conjugant simultaneously, and adopt rivet to be fixed on the side crossbeam steel pipe, be shaped on some hooks in the running-board bracket outside, locate to be equipped with grillage in the inboard of running-board bracket (near wall) again.

Dustproof life net is mounted on and supports between the perpendicular steel pipe, on dustproof life net, be shaped on respectively and arrange, arrange down hanging hole and some gravity vents in some, row's hanging hole in the dustproof life net is passed and is fixed on the hook of main beam steel pipe inboard, to arrange down again on the hook that hanging hole is fixed in the running-board bracket outside, make in the space of dustproof life net between the main beam steel pipe and the running-board bracket outside and be a wooden dipper shape, and arrange therein, arrange down and install one deck safe life-saving net between the hanging hole additional, also can before dustproof life net, add again simultaneously and mount canvas.

Also the life net one end cover that prevents dust can be hung on the hook in the running-board bracket outside, the other end is hitched on the hook that is packed in intertie or on the hook of main beam steel pipe.
