Detailed description of the invention
Below in conjunction with accompanying drawing, the invention will be further described.
Embodiment one
With reference to shown in Fig. 1, the present invention provides a kind of steel pipe scaffold dish to buckle, and described dish buckles 1 for cross block, and dish is buckled the external diameter of the circular hole 2 that 1 center is provided with through, the diameter of circular hole 2 and vertical rod 8 and matched.Dish is buckled four over-hang part ends of 1 and is respectively equipped with a jack run through 3, is often provided with a socket 4 for the vertical brace (not shown) of grafting run through between adjacent two jacks 3.
During use, generally cross bar (not shown) being connected with plug-in unit (not shown), plug-in unit is up big and down small wedge shape, inserts in jack, can form self-locking structure.Because in use, the power that cross bar bears is mostly downward, when such as people or weight are pressed downward against, scaffold to bear downward load, therefore the plug-in unit of wedge shape can be more slotting more tight, get loose without top-down, simultaneously because cross bar is clipped in the middle of two vertical rods 8, without left and right play, therefore two-way self-locking structure, safety and stability are formed.During use, four cross bars of grafting and four vertical braces simultaneously can be buckled on 1 at dish, four cross bars 90 ° each other, four vertical braces also each other 90 °, between adjacent cross bar and vertical brace 45 ° each other, each rod axis intersects at a bit, whole axially loadeds, without additional stress, mechanical property is good, connects reliable.
Embodiment two
With reference to shown in Fig. 2, in the present invention, jack 3 one end extends to corresponding circular hole 2 edge and overlaps with circular hole 2, circular hole 2 is made to form the notched annular of non-tight, during use, wedge insert is plugged in jack 3, can effectively reduce the gap between vertical rod 8 and cross bar so that the connection of vertical rod 8 and cross bar is more stable, effectively prevent displacement.This it be designed to significantly alleviate dish and buckle the weight of 1, and structure is simpler, stable performance, energy-conserving and environment-protective.
Embodiment three
With reference to shown in Fig. 3, the upper and lower of circular hole 2 of the present invention is provided with the crimp rings 5 for crimp with vertical rod 8, and described crimp rings 5 is annular, coaxial with circular hole 2 and internal diameter is equal.
Traditional steel pipe scaffold manufacture method adopts welding manner mostly, this mode needs solder, solvent and abluent etc., complicated operation, contaminated environment, power consumption is big, corrosivity is strong, and after life-time service, pad is probably due to oxidation reaction occurs damaged or bursts apart, affect the service life of scaffold, threaten the life and health of workmen.Crimp and connect also known as pressure, it is simply that at normal temperatures, make a kind of metal and the metalwork generation plastic deformation being connected form integrated a kind of method of attachment of metal structure with cold weld instrument or equipment.It is characterized in: (1) is without solder, solvent and abluent etc., easy to operate；(2) corrosion-free, without heat affecting, free from environmental pollution；(3) it is suitable for the steel pipe support of various sizes, there is good mechanical property；(4) crimping can realize air-tightness connection and have good environmental suitability.Welding manner is changed into crimping mode, is that scaffold makes the significant innovation in field and tremendous breakthrough.For a long time, crimping mode fails to introduce scaffold always and makes field, traces it to its cause, and is do not have suitable parts to be suitable for crimping.The upper and lower of circular hole 2 of the present invention is provided with the crimp rings 5 for crimping with vertical rod 8, and described crimp rings 5 is in annular, coaxial with circular hole 2 and internal diameter is equal, by crimp rings 5, dish is buckled 1 and crimps with vertical rod 8 and be connected.It is connected with vertical rod 8 crimping by crimp rings 5, replaces the mode of welding with crimping so that difficulty of processing is greatly reduced, working (machining) efficiency is significantly improved.The present invention does not need welding equipment, it is not required that electrode wire and welding gas, and production process can be saved more than 70% electricity and carbon emission amount is greatly decreased.
Embodiment four
With reference to shown in Fig. 4, the circumference of described crimp rings 5 is uniformly arranged opening 6.Be conducive to making crimp rings 5 and the convenient laminating of vertical rod 8 at the circumferentially disposed opening of crimp rings 56, strengthen the stability of crimping.
Embodiment five
With reference to shown in Fig. 5, the upper and lower of described circular hole 2 is uniformly distributed the crimp block 7 of protrusion.During use, crimp block 7 being crimped with vertical rod 8, owing to leaving gap between adjacent crimp block 7, can effectively promote dish to buckle the laminating of 1 and vertical rod 8, dish buckles 1 can be closely coupled with vertical rod 8.Meanwhile, crimp block 7 processes simplicity, it is possible to decrease cost of manufacture.
With reference to shown in Fig. 1-Fig. 6, as further preferred embodiment, the edge that described dish buckles 1 is curved.Dish is buckled the edge designs camber of 1, it is possible to significantly alleviate dish and buckle the weight of 1, and structure is simpler, stable performance, energy-conserving and environment-protective.It is standard crux compared to conventional roulette button, the combination that curved edge can place another root vertical rod or another root vertical rod and dish is buckled, save space, stacking convenience.
The above is only the preferred embodiment of the present invention, and protection scope of the present invention is not limited merely to above-described embodiment, and all technical schemes belonged under thinking of the present invention belong to protection scope of the present invention.It should be pointed out that, for those skilled in the art, some improvements and modifications without departing from the principles of the present invention, these improvements and modifications also should be regarded as protection scope of the present invention.
