Abstract
The utility model relates to a fastening device for building construction, in particular to a safety anti-skid fastener for a steel pipe scaffold, comprising a single base plate or an upper and a lower two base plates between which an angle is formed, a cover plate of which one end is hinged with the base plate through fixing pins, fastening bolts and nuts. The safety anti-skid fastener is characterized in that the middle part of the inner circular arc face of the arched part of the cover plate is adhered with an anti-skid pad, and the connecting part of the other end of the cover plate is provided with a T-shaped opening. The utility model has simple structure, good safety and strong anti-skid ability, and the fastening bolts are not easily slid.
Description
One, technical field
The utility model relates to the fastening appliance that a kind of building operations is used, and particularly a kind of steel pipe scaffold is carried out the fastening anti-skidding fastener of steel pipe scaffold safety.
Two, background technology
In building construction process, particularly to the construction of highrise building, all adopt for easy construction scaffold erecting, the mode of support, scaffold, falsework, support, bearing frame of building construction with steel pipe etc. all adopts steel tube scaffold clasp.This fastener is by being mutually certain angle or vertical substrate up and down and constituting with the cover plate of each substrate hinge joint, and substrate and cover plate are the stiff dough driving fits through the fastening steel pipe of fastening bolt, are easy to skid and the non-skid property deficiency, and be especially easier to be like this when the steel pipe profile has variation; And the fastening bolt of the connecting portion of the cover plate of fastener and substrate is easy to slippage, loosening, particularly fastener has on distortion or its when adhering to other foreign matters, fastening bolt is not just, cause nut and the loose contact of cover plate face, Gu will there be potential safety hazard in not tight bolt slippage in use, cause safety relatively poor, there is the scaffold collapse accident to take place frequently, and causes casualties and property loss.
Three, summary of the invention
The purpose of this utility model be intended to overcome the deficiencies in the prior art provide a kind of simple in structure, safety good, skid resistance is strong, the anti-skidding fastener of the not eely steel pipe scaffold safety of bolt.
The utility model is to adopt such technical scheme to realize, the anti-skidding fastener of a kind of steel pipe scaffold safety, include single substrate or upper and lower two substrates at an angle to each other, an end through steady pin and hinged cover plate, fastening bolt, the nut of substrate, the bow type portion inner arc surface middle part that is characterized in cover plate is bonded with slipmat, and cover plate other end connecting portion is provided with T type opening.
By the fastener that the utility model provides, owing to be bonded with slipmat, with the fastening steel pipe of substrate the time, be soft driving fit therefore at the bow type portion inner arc surface middle part of cover plate, be difficult for skidding, thereby strengthened the cling property of steel pipe scaffold widely.Offer T type opening at the connecting portion of patch ends, make fastening bolt that bigger scope be arranged, even fastener slightly is out of shape or with foreign matter, bolt all can vertically correctly be fixed in the fastener by nut in all cases, thereby has eliminated the hidden danger of slippage.The wood utility model is simple in structure, safety good, skid resistance is strong, and bolt is difficult for slippage, can avoid the generation of security incident greatly.
Four, description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the cover plate schematic diagram;
Fig. 3 is that the A of Fig. 2 is to view;
Fig. 4 is the schematic diagram of a substrate.
Five, the specific embodiment
Embodiment of the present utility model is described with reference to the accompanying drawings, as Fig. 1, Fig. 2, shown in Figure 3, the anti-skidding fastener of a kind of steel pipe scaffold safety, include single substrate or upper and lower two substrates at an angle to each other 5, an end through steady pin 8 and substrate 5 hinged cover plate 3, fastening bolt 6, nut 7, the bow type portion inner arc surface middle part of described cover plate 3 is bonded with slipmat 1, and cover plate 3 other end connecting portions 4 are provided with T type opening 2.
In the embodiment shown in the accompanying drawing 1,2,3,4, the two ends of " T " of the T type opening on the connecting portion 4 upper end are arc surface.Slipmat 1 adopts vulcanized rubber mat.The arc surface of cover plate 3 and substrate 5 bow type portions is that cambered surface is connected with the right-hand member connecting portion.
