Abstract
The utility model discloses an orthogonal fastener of a steel pipe with double upright posts. Three cambered notches are arranged at a fastener body and are distributed on the fastener body in a cross shape, cambered pressing rings which are respectively matched with the three notches are hinged in the middle of the fastener body, one end of each pressing ring is hinged to the fastener body, and the other end of the pressing ring is connected with a bolt arranged on the fastener body by a nut. The fastener can be tightly fixed on the steel pipe of a scaffold by the blot and the nut, and consequently, the scaffold can be fastened. Because the fastener fastens the two upright posts and a transverse post of the scaffold synchronously, the loading force can be evenly distributed to the two upright posts, and the intensity and the fixedness of the scaffold are ensured, so the safety of the scaffold is increased.
Description
Technical field:
The utility model relates to a kind of scaffold clasp, and specifically a kind of two pole steel tube right-angle couplers used when building steel pipe scaffold belong to building engineering construction facility technology field.
Background technology:
Use the in short supply day by day of soil owing to build, highrise building can get more and more, continuous development along with depth of building, in the construction scaffold build highly also more and more higher, Ministry of Construction's requirement in " construction safety check criteria ", scaffolding height surpasses the outrigger of 25M and not enough 50M, should take strengthening measures such as two pole steel tubes, at present, the on-the-spot employed pair of standpipe scaffold clasp of building engineering construction adopts single right-angle coupler mostly, adopting the scaffold floor classification not simultaneously, its cross bar, vertical rod stress form difference, mode of transfer force is also different, does not really reach two even stressed load effects of vertical rod, and it is safe in utilization to influence construction scaffolding, there is potential safety hazard
The utility model content:
The utility model is for avoid above-mentioned existing in prior technology weak point, a kind of pair of pole steel tube right-angle coupler is provided, the stressed load of the scaffold that can distribute, thereby the intensity and the stability of assurance scaffold, raising safety standard effective and reasonablely.
The utility model technical solution problem adopts following technical scheme:
Two pole steel tube right-angle couplers, fastener body is provided with three circular arc recesses, three recesses are crossing distribution on fastener body, be hinged with three circular arc pressure rings that cooperate one by one with described recess at the fastener body middle part, one end of pressure ring is hinged on the fastener body, and the other end of pressure ring is connected with bolt on the fastener body by nut separately.
Design feature of the present utility model also is:
Described fastener body and pressure ring are made by cast steel.
Described pressure ring is hinged on the fastener body by rivet.
Described bolt is a T type fastening bolt, and bolt and fastener body flexibly connect.
Compared with the prior art, the beneficial effects of the utility model are embodied in:
The utility model fastener comprises fastener body and circular arc pressure ring, offer three on the fastener body and be the circular arc recess that cross is arranged, three pressure rings cooperate one by one with three recesses, one end of pressure ring is hinged on the fastener body by rivet, two pressure rings that are in the fastener body homonymy fasten two root posts of scaffold, another pressure ring fastens the cross bar of scaffold, the other end of pressure ring is connected with bolt on the fastener body by nut separately, bolt, nut can be fastened on fastener on the steel pipe of scaffold, and then scaffold is fastened.Because of fastener of the present utility model buckles two vertical rods and a cross bar of scaffold simultaneously, load forces can be uniformly distributed in two vertical rods, guaranteed the intensity and the stable degree of scaffold, the safety that has improved scaffold.

Fig. 1 is the front view of the utility model fastener.
Fig. 2 is that the A-A of Fig. 1 is to sectional view.
Fig. 3 is the user mode figure of the utility model fastener.
Fig. 4 is the user mode figure of another embodiment of the utility model fastener.
Number in the figure: 1, fastener body, 2, recess, 3, nut, 4, bolt, 5, pressure ring, 6, rivet, 7, vertical rod, 8, cross bar, 9, tubing, 10, scaffold floor, 11, bamboo pin hand sheet.
Below pass through the specific embodiment, and the utility model is described in further detail in conjunction with the accompanying drawings.
The specific embodiment:
Embodiment 1: referring to Fig. 1, Fig. 2, two pole steel tube right-angle couplers of present embodiment, fastener body 1 is provided with three circular arc recesses 2, three recesses are crossing distribution on fastener body, wherein two recesses are in the homonymy of fastener body, the plane at its recess place is parallel with fastener body, another recess is in the opposite side of fastener body, the plane at its recess place is vertical with fastener body, be hinged with three circular arc pressure rings 5 that can cooperate one by one with described recess at fastener body middle part, one end of pressure ring is hinged on the fastener body by rivet 6, and the other end of pressure ring is connected with bolt 4 on the fastener body by nut 3 separately; For the rigidity that guarantees fastener and fastener fasten the intensity of scaffold, fastener body 1 and pressure ring 5 can adopt the ZG230-450 cast steel among the GB11352 to make.
Bolt 4 can adopt T type fastening bolt, and they and fastener body 1 flexibly connects, when unclamp nut 3 with pressure ring 5 when bolt 4 is opened, bolt can rotate on fastener body 1.
Shown in Figure 3, when scaffolding erecting, column 7 adopts arranged side by side two, cross bar 8 adopts one, this kind scaffold is referred to as two pole steel tube scaffolds, when using fastener of the present utility model, fastener body 1 is placed between vertical rod 7 and the cross bar 8, plane, place two recesses parallel with fastener body fasten two vertical rods, plane, a place recess vertical with fastener body fastens cross bar, again will with three recesses separately three pressure rings of corresponding matching be fastened on respectively on two vertical rods and the cross bar, and be fastened on the bolt on the fastener body by nut one by one, so far, scaffold is just set up securely and is finished.On cross bar 8, lay some tubing 9 by rolled piece, and on tubing, lay stamped steel scaffold floor 10, just can carry out construction operation, constructor or construction material, are uniformly distributed between two root posts by the conduction of tubing 9 and cross bar 8 stamped steel scaffold floor applied force, make scaffold stressed evenly, load distribution is reasonable, has guaranteed intensity, rigidity and the stability of scaffold, the safety that has improved construction operation.
The view directions of present embodiment scaffold is that cross bar 8 is parallel to each other with the body of wall of building.
Embodiment 2: referring to Fig. 4, present embodiment is with embodiment 1, and different is, the scaffold of being built does not adopt the stamped steel scaffold floor, can adopt bamboo pin hand sheet 11, the view directions of scaffold is different from embodiment 1, and present embodiment scaffold cross bar 8 is vertical mutually with the body of wall of building.
