Abstract

The utility model relates to a stereo combined scaffold. Upright posts and cross bars are fixed into N-shaped frame structure units with stairway foot steps; each unit is arranged around a house at a certain interval; two adjacent units are detachably fixed on the upright posts by cross supporting rods; a foot board is arranged above the two adjacent units; ends of the upright posts are provided with demountable joint structures to conveniently stack from the up and the down sides and joint from the left and the right sides each unit to form the whole body of the scaffold. The utility model is a structure array pattern which is convenient for assembling, disassembling, packing and long distance conveying, has sufficient rigidity and stability, can conspicuously improve the efficiency of forming a scaffold, save material and reduce the construction cost.

Description

Stereo combined scaffold

The utility model relates to a kind of building operations scaffold.

Traditional scaffold is to tie up with mao bamboon or steel pipe, or connects by bolt, union, makes that to set up the scaffold man-hours requirement big, and the desired structure material is many, and required connector is many, cause to account for the stockyard phenomenon more, and loss greatly, energy waste, be not easy to dismounting again.

The purpose of this utility model is to overcome the defective of prior art, and a kind of three-dimensional combined scaffold of being convenient to dismounting, saving of labor, material-saving is provided, to reduce loss, energy conservation.

The utility model is achieved by the following scheme: it is fixed into by vertical rod, cross bar contains the shape frame construction unit that stair are stepped on shelves, each unit with a determining deviation be arranged in build a house around, between adjacent Unit two by removable being fixed in the vertical rod of strut of intersecting; Foot pedal is shelved on top, Unit two; The end of vertical rod has the releasable connection structure of each upper and lower stack in unit.

This scaffold utilization has been shaped On shape frame construction unit is undertaken by connected mode, following stack, a left side, a left side also connects the scaffold that forms around the house all around, for the high-rise operation of construction worker, it is a kind of installation, raise, dismounting is all very convenient, be convenient to the to case structural group combination pattern of long-distance carrying, has enough rigidity and stability, the defective of having avoided traditional scaffold expense of taking a lot of work to expect, can make and set up scaffold efficient and significantly improve, save structural meterials, can save for 80% dismounting man-hour, reduce half manpower, the weight ratio steel pipe scaffold is light by 30%, greatly reduce construction costs, can be applicable to the indoor and outdoor body of wall and whitewash, the facility maintenance, the installation of industrial equipment, work high above the ground such as maintenance.

Describe in further detail by above-mentioned accompanying drawing embodiment.

Three-dimensional combined scaffold (referring to Fig. 1-8) is fixed into by vertical rod (4), cross bar (5) welding of different size length and contains the shape frame construction unit that stair are stepped on shelves (3), vertical rod, cross bar adopt 2 millimeters thick steel plates to strike out " ∪ " shape (Fig. 5), curved fitting in the opening part to gain in strength and rigidity

The shape structure is equivalent to door, walking when working for people, 1.8 meters of overall heights, 1.1 meters of overall widths.

Each unit with 1.8 meters spacings be arranged in wait to build a house around (Fig. 2), strut (2) by the steel pipe system of intersecting between adjacent Unit two is fixed in the vertical rod (4), detachably, this syndeton (Fig. 3) is promptly welded pin junction plate (6) in two places up and down in vertical rod, pin (7) welds one with junction plate again, fixture block (9) is equipped with in the end of pin, hinged by pin (8), but require the fixture block can not be greater than pin, be advisable with equal diameter, generally one of fluting is cut flatly on pin or fixture block, and opens oblong slots on fixture block, and flat department and groove are equipped with fixture block can be gone up, under pull 90 °.The top of adjacent struts (2) strikes out the through hole that the reprocessing of flat department shape is slightly larger than pin, and strut just can be set on the pin to be blocked by fixture block is fixed (Fig. 3 is inserted in state for strut, and imaginary line is a strut kayser state).

Foot pedal (1) is shelved on top, Unit two, and the foot pedal ligation that available plank or bamboo chip are compiled is on vertical rod or cross bar, and the increase safety is gone along with sb. to guard him in setting.

Since this scaffold can upper and lower stack to adapt to highrise building needs, therefore the upper and lower end of every vertical rod all is preset with syndeton (Fig. 4), it is required to do each unit stack, detachably.Promptly be welded to connect piece (10), be fastenedly connected, be about to upper and lower two vertical rods and be fixed as one by bolt, nut at the both ends of vertical rod.

Vertical rod contacts an end with ground can be provided with raising device (Fig. 6), and the utilization of this device is welded on the contiguous block (10) of pole tip, loads onto bolt, and inside and outside tight by the nut assembly, this device generally is useful in inner wall render, can raise 30 centimeters.

Vertical rod contacts an end with ground also can be provided with extension fixture (Fig. 7-8), this device comprises the hound (11) that is fixed in the porthole, its top connects high piece (12), be fastenedly connected by bolt, nut and the contiguous block (10) that is welded on pole tip, this device generally is useful in building below three layers.
