Description

Multifunctional bowl button steel pipe scaffold

The utility model relates to the steel pipe scaffold of the realm of building construction, particularly a kind of multifunctional bowl button steel pipe scaffold.

Existing bowl fastening type steel pipe scaffold, owing to can only connect 4 cross bars or brace simultaneously on each bowl snapping head, brace can not be arranged on the node sometimes owing to this restriction.In addition, existing bowl fastening type steel pipe scaffold can only be made the lateral plane diagonal brace, can not make space or horizontal plane diagonal brace, thereby causes the poor stability of scaffold, even distortion is collapsed.Bracing frame as the Fig. 9 in the application number 86201080U patent specification is a geometrically unstable system, under the effect of horizontal force with easy deformation even collapse.The cross bar of this scaffold can not be regulated vertical pole ' s span arbitrarily owing to be normalization simultaneously.In addition, when this bowl fastening type scaffold and other steel pipe scaffold interconnected, its spacing was not necessarily determined, therefore brings certain trouble to construction.

The purpose of this utility model provides and a kind ofly can make adjustable tie-rod both can make adjustable brace, also can make adjustable cross bar, both adjustable length simultaneously, and adjustable angle again can strengthen the resistance to overturning of scaffold, guarantees the steel pipe scaffold of construction safety.

The purpose of this utility model is achieved by the following scheme: the adjustable tie-rod of this scaffold comprises sleeve pipe, telescoping tube, and sleeve pipe one end is provided with gripping sleeve, and telescoping tube inserts sleeve pipe and fixes by gripping sleeve.The end of sleeve pipe and telescoping tube is flat-shaped, with center rivet itself and fastener is fused, simultaneously still can center rivet between sleeve pipe, telescoping tube and the fastener to be that pivot is relative rotate.The locking device of said gripping sleeve and fastener can be a bolt type, also can be Wedge-type.

The special-purpose cross bar of formwork of the present utility model is at the two ends of shaped steel or light-gauge steel section the cross bar joint to be set to form, and can replace former cross bar and wooden frame.

Inter cross bar of the present utility model two ends are connected to the n shaped steel plate, wherein have the n shaped steel plate of an end to have breach, can guarantee that when scaffold vertically is provided with Inter cross bar Inter cross bar needn't interlock and set up, and can be arranged to straight line.

The utility model compared with prior art has reasonable in designly, easy to operate, meets the actual requirement of construction, can improve the total bearing capacity of scaffold, guarantees construction safety.In addition, the utility model is designed to adjustable tie-rod both can adjust length, can adjust angle again, can bear the active force that stretches and compress.Simultaneously both adjustable brace can be made, adjustable cross bar can be made again.During as adjustable brace, it can be connected in the scaffold rod member at any time, finishes horizontal plane diagonal brace or space diagonal brace.During as adjustable cross bar, it can regulate vertical pole ' s span arbitrarily, and bowl fastening type steel pipe scaffold and other common steel tube scaffold are interconnected.Thereby remedied deficiency of the prior art, strengthened the resistance to overturning of scaffold.

Below in conjunction with accompanying drawing the utility model is illustrated.

Embodiment: as Fig. 1 to Fig. 9, the utility model is made of a plurality of unit constructions, by vertical rod 1, cross bar 2, adjustable tie-rod 3, adjustable seats 4, the special-purpose cross bar 5 of formwork, attached members such as Inter cross bar 6 and scaffold floor, protective screening, railing, pitman are formed jointly respectively for it.Wherein the adjustable tie-rod 3 shown in Fig. 3,4 comprises sleeve pipe 3-2, telescoping tube 3-4, and sleeve pipe 3-2 one end is provided with gripping sleeve 3-3, and telescoping tube 3-4 inserts in the sleeve pipe 3-2, is fixedly clamped by gripping sleeve 3-3 after adjusting length.The end of sleeve pipe 3-2 and telescoping tube 3-4 is flat-shaped, can be convenient to rivet 3-5 and fastener 3-1 fuses, simultaneously still can center rivet 3-5 between sleeve pipe 3-2, telescoping tube 3-4 and the fastener 3-1 to be that pivot is relative rotate, to satisfy the requirement of installation different angles.During installation, fastener 3-1 can be locked on vertical rod 1 or the cross bar 2, the locking device of gripping sleeve and fastener can be a bolt type, as shown in Figure 3, also can be Wedge-type, as shown in Figure 4.When this locking device adopts bolt type, then tighten the nut 3-6 on the fastener 3-1, the fastener fastening is good with length adjustment then, tighten the bolt 3-6 on the gripping sleeve 3-3, with gripping sleeve telescoping tube 3-4 is clamped and get final product (see figure 3).When locking device adopts Wedge-type, then hammer the voussoir on the clasp into shape, with the fastener fastening, adjust length, hammer grips the voussoir 3-6 that tightly puts, and with gripping sleeve telescoping tube 3-4 is clamped and gets final product (see figure 4).This is adjustable, and tie-rod 3 promptly can be adjusted its length, can adjust angle again, can bear the active force of Compression and Expansion.Simultaneously can make adjustable brace or adjustable cross bar.As adjustable brace, it can be connected in the scaffold rod member at any time, can make plane diagonal brace or space diagonal brace, as Fig. 7, shown in Figure 8.As adjustable cross bar, it can regulate the spacing of vertical rod 1 arbitrarily, and bowl fastening type steel pipe scaffold and other steel pipe scaffold are interconnected, as shown in Figure 2.Thereby remedied the deficiency of existing bowl fastening type steel pipe scaffold.

As shown in Figure 9: the special-purpose cross bar 5 of formwork can be given full play to down the bearing capacity of bowl button, provides a kind of simple and efficient and economic important component for the template in the building operations supports.Special-purpose cross bar 5 usefulness shaped steel of this formwork or light-gauge steel section constitute, and the two ends of shaped steel 5-2 are provided with cross bar joint 5-1 becomes the special-purpose cross bar 5 of formwork.This cross bar can replace former cross bar 2 and wooden frame, and a thing dual-purpose and bearing capacity are big, as shown in Figure 1.

In the building operations of southern area, the common practice is that scaffold floor is erected on vertical cross bar, so Inter cross bar need vertically be set.These Inter cross bar 6 two ends are provided with the n shaped steel plate, wherein have the n shaped steel plate of an end to have breach, can allow the n shaped steel plate of another Inter cross bar 6 inject this breach, make Inter cross bar 6 be straight line when vertically setting up, shown in Fig. 5,6.Like this, scaffold floor just can be set up on the center line of Inter cross bar, makes this scaffold floor stressed even and firm, guarantees construction safety.
