Background technique
Along with the quick growth of modern development and population, all kinds of engineering construction project scale expanding day, high buildings and large mansions acquisition approval and rise to improve space availability ratio, and adopt its construction height of the building of concrete structure to be limited, the portion requirements of modern social development can not be met, so existing a lot of high-rise adopts steel structure to build.
In housing beam work progress, there is multiple working surface at different floor.There is falling of fragmentary steel for preventing the operation of eminence floor and slipping of personnel is fallen, therefore need to lay safety net in every floor face.Above original girder steel, lay the mode of safety net, the safety that safety net can ensure to lay composite floor workmen is simultaneously laid in girder steel lower flange, namely hangs safety net down.Lower extension safety net needs safety net fixture to be fixed when hanging, and fixture needs the lower flange being fixed on girder steel, is hung on fixture by safety net after fixing again.With regard to present circumstances, each unit in charge of construction generally uses a kind of safety net fixture needing manually to be screwed bolt.
Hanging safety net adopts standardized safety net to link up with at present, can meet the primary demand of construction.Former safe network folder is made up of wide U-shaped clamping plate, fixing bolt.The threaded bolt hole of tool is offered in the middle of U-shaped clamping plate upper end, by fixing bolt through perforate directly twist dead on girder steel to realize the fixing of fixture, safety net then directly hangs on the bolt that exposes above U-shaped clamping plate, this safety net clamp structure simply still mounting or dismounting is comparatively loaded down with trivial details, the safety net fixture of a standard floor is according to 1500 meters, then peace is torn work operation open and twisted 3000 bolts.If therefore a Super High project, according to 80 layers of meter, only safety net fixture, need twist 240,000 times altogether, workload is huge, and due to the tightness of bolt be by manual control, have a lot of uncertain factor, Security is difficult to ensure completely, mainly there is following problem:
Dismounting complex steps when 1, using.
2, usage quantity is huge.
3, artificial temporary fixed time be difficult to the tightness ensureing each fixture, horizontal force resistant by man's activity larger.
4, work surface is in eminence, and the installation time is longer causes larger potential safety hazard.
5, non-Unitary, the easy collapsing loss of bolt.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, there is provided a kind of self-locking to pacify fast and tear positional safety clamp open, solving existing fixture peace, to tear operation open loaded down with trivial details, a difficult problem for potential safety hazard is there is during mounting fixture, avoid the problem that when artificially installing, bolton is not in place, unitary design solves the problem of the easy collapsing loss of conventional brace bolt, improves the whole efficiency of trouble free service.
The purpose of this utility model is achieved in that a kind of self-locking is pacified fast and tears positional safety clamp open, it mainly comprises locking element and two U-shaped clamping plate, described locking element is installed between the upper end of two U-shaped clamping plate by bearing pin, and it is affixed with bearing pin, the torsion spring for controlling locking element angle of swing is provided with between the two ends of described bearing pin and two U-shaped clamping plate, described locking element is made up of the special-shaped Circular Steel with certain outer spiral curvature, and offers multiple lanyard hole for hanging safety rope fag end on its surface.
Teflon gasket is installed additional at the surface of contact of described locking element and U-shaped clamping plate.
Accompany reinforcement block in the middle of two U-shaped clamping plate lower ends, the antiskid sawtooth that described reinforcement block upper end is arranged is for providing larger frictional force between fixture and edge of a wing steel plate.
Described U-shaped clamping plate and locking element are respectively arranged with the butterfly that the cooperatively interacts maximum angle of swing for limiting lock gripping members.
Compared with prior art, the utility model has following beneficial effect:
1, self-locking pacifies that to tear positional safety clamp mounting or dismounting open very convenient fast, eliminates a large amount of time of twisting bolt, has meanwhile also evaded the potential safety hazard brought in high-altitude long working, improve the efficiency of trouble free service;
2, the principle that utilizes similar steel plate to press from both sides forms self-locking effect, uses axle spring and safety net load to make fixture locking cleverly, avoids and to twist not in place and potential safety hazard that is that arrive when bolt is twisted in manual operation, it also avoid the people of fixing bolt for loss simultaneously;
3, utilize self-locking effect, greatly can increase the power of tightening, fixture quantity can be reduced further, improve efficiency of construction, reduce the operating risk of safe teams and groups simultaneously.
