Abstract
The utility model discloses square bar column top, a kind of high-altitude cutting operation safety aid, it comprises the spaced practical upper bound structure of upper and lower coaxial line and lower constraint structure, be fixedly linked by bearing bar between described practical upper bound structure and lower constraint structure, described lower constraint structure has perforate in the horizontal direction that connect lock bolt, and described practical upper bound structure and lower constraint inside configuration have the hole suitable with square steel shape to be set with.The beneficial effects of the utility model are: cutting after the vertical square steel of installation need not being removed, directly in square steel top operational, save a large amount of human input, save the duration, effectively can ensure the controllability of the square steel excised when high operation, without the potential safety hazard of falling object from high altitude, economic and practical, can repeat to be suitable for.
Description
Technical field
The utility model relates to cutting operation safety aid, and the utility model particularly relates to square bar column top, high-altitude cutting operation safety aid.
Background technology
In order to the object reaching publicity and beautify, inside some high building roofing top parapets, some copies or picture are all set, on rear side of billboard, (majority is rectangular steel tube to vertical supporting shaped steel, be called for short square steel) constructed after, consider the impact of whole structure or design alteration, all vertical square steel tops need to excise certain length, owing to being in high empty position and having constructed, vertical square steel cuts after all removing, and then reinstall and need to drop into a large amount of manpower, construction period is also longer.If directly carry out at square steel top the potential safety hazard that cutting operation exists again falling object from high altitude.
Summary of the invention
The purpose of this utility model is the deficiency overcoming prior art, provides a kind of square bar column top, high-altitude cutting operation safety aid of the potential safety hazard without falling object from high altitude.
In order to achieve the above object, the technical solution adopted in the utility model is:
Square bar column top, a kind of high-altitude of the present utility model cutting operation safety aid, it comprises the spaced practical upper bound structure of upper and lower coaxial line and lower constraint structure, be fixedly linked by bearing bar between described practical upper bound structure and lower constraint structure, described lower constraint structure has perforate in the horizontal direction that connect lock bolt, and described practical upper bound structure and lower constraint inside configuration have the hole suitable with square steel shape to be set with.
The beneficial effects of the utility model are: cutting after the vertical square steel of installation need not being removed, directly in square steel top operational, save a large amount of human input, save the duration, effectively can ensure the controllability of the square steel excised when high operation, without the potential safety hazard of falling object from high altitude, economic and practical, can repeat to be suitable for.
Accompanying drawing explanation
Fig. 1 is the front view of square bar column top, a kind of high-altitude of the present utility model cutting operation safety aid;
Fig. 2 is the top view of the structure shown in Fig. 1.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described in detail.
Square bar column top, a kind of high-altitude of the present utility model as shown in drawings cutting operation safety aid, it comprises the spaced practical upper bound structure 3 of upper and lower coaxial line and lower constraint structure 6, be fixedly linked by bearing bar 4 between described practical upper bound structure 3 and lower constraint structure 6, described lower constraint structure 6 has perforate in the horizontal direction that connect lock bolt 7, and described practical upper bound structure 3 and lower constraint structure 6 inside have the hole suitable with square steel shape to be set with.
Adopt the construction method of this device as follows:
First hoop horizontal lines is drawn at the plan cutting position 5 of vertical square steel, then this device is vertically placed, worn downwards by vertical square steel top 2, make the centre position of plan cutting position horizontal lines gap between the practical upper bound structure 3 and lower constraint structure 6 of device;
Locked by the lock bolt 7 of device lower constraint structure 6 both sides, assurance device does not loosen;
Then use cutting tool to carry out the cutting of hoop square steel along intending cutting horizontal mark line, it is inner that the square steel top 2 after cutting and separating will be limited to device practical upper bound structure 3 temporarily, can not run-off the straight fall danger;
Use handling appliance by the hole for hoist 1 that is drilled with at square steel top 2 in advance by square steel top cut-out straight up by hanging out in device practical upper bound structure 3 and being placed on appointed place;
The lock bolt 7 of whirligig lower constraint structure 6 both sides makes device lower constraint structure 6 be separated with square steel bottom reserved part 8, upwards proposes device and constructs to other scope of operation.
Claims (1)
