Abstract
The utility model provides a plug-connected gravitational self lock scaffolding, comprising a plurality of vertical bars, a plurality of wheel disks arranged on the vertical bars at intervals, a plurality of cross bars, a plurality of bolts arranged on the end of cross bars; the wedges of the bolts are inserted in openings of the wheel disks, which is characterized in that the wheel disk comprises a plurality of circular cylinders and a plurality of trapezoid inserting lugs with openings symmetrically arranged between circular cylinders; the bolt comprises a plurality of trapezoid wedges and a plurality of plugs which one side is provided with a concave platform and the other side is provided with an arc-shaped lug. The utility model can not only enlarge the contact area of the bolt and the wheel disk, improve the intensity of the wheel disk but also make the stability higher when bearing more pressure in matching connection; in addition, the utility model is an ideal, safe and reliable new type scaffolding in extensive practice range with the advantages of convenient and immediate arrangement, long durability and saving material.
Description
Technical field
The utility model relates to a kind of scaffold for building, especially a kind of easy for installation and scaffold that just can lock voluntarily by gravity.
Background technology
Scaffold is the indispensable apparatus of building trade.Usually be made of cross bar, montant, brace and fastener set thereof, it can be assembled as required at the construction field (site).At present the scaffold that uses need mostly by bolt and nut carry out fastening, inefficiency not only, and the potential safety hazard that exists is quite big is installed.In the practical application, because of the scaffold security incident that causes of collapsing takes place again and again, both incured loss through delay the construction operation time limit, the safety of the property and the person in serious threat again.For this reason, Chinese patent discloses a kind of " scaffold ", and its patent No. is 982049803, and it is that axis direction at montant is provided with the wheel button at interval, in crossbar end polarized plug is set, and the wedge-like portion of plug is inserted in the opening that wheel buckles.It is quick that it has a dismounting, and convenient transportation, component such as are difficult for losing at characteristics.But still there is a following deficiency: the one, the wheel button is the sheet material of equal thickness, not only takes material, and is easy to generate distortion under gravity; The 2nd, it only is the some contact that plug is buckled contacting of opening and montant with wheel, easily causes rocking of scaffold, thereby influences its firm performance.Therefore, be necessary prior art is improved.
Summary of the invention
The utility model is intended to overcome the deficiency of prior art, provides a kind of and can not be out of shape, can not rock, and is sturdy and durable, material-saving, the plug-in type gravity self-locking scaffold that stability is high.
The utility model is realized by following technical proposal: it comprise montant with and go up the wheel disc that is provided with at interval, cross bar with and the latch of end, the voussoir of latch inserts in the wheel disc opening, it is characterized in that wheel disc is made of cylinder and the slotting ear that is symmetricly set on the band trapezoid-shaped openings between the cylinder, latch is provided with concave station by trapezoidal voussoir and one side, and opposite side is provided with the plug formation that arc is moved close to somebody's ear.
Slotting ear outer wall between described wheel disc cylinder outer wall and the cylinder is up big and down small trapezoidal walls, so that under the situation that materials are economized most, possesses enough load bearing stengths.
Slotting ear on the described wheel disc, its opening with contacted three faces of voussoir be up big and down small trapezoidal faces, be used to increase the contact surface with voussoir, so that improve scaffold stability.
The voussoir inner face of described latch is the arc surface matched with montant, and its excess-three face is for inserting the up big and down small trapezoidal faces that the ear opening adapts with wheel disc.
The plug of described latch is positioned at the top of voussoir, and the concave station of one side is used to connect crossbar end, and the width that the arc of opposite side is moved close to somebody's ear is greater than the voussoir width, so that when contacting with montant, increases the contact area with montant, improves the stability of scaffold.
The utility model compared with prior art has following advantage and effect: because such scheme, both increased the contact area of latch and wheel disc, improved the intensity of wheel disc again, make them when connecting, the pressure that bears is big more, and stability is high more, it also has easy for installation, quick in addition, sturdy and durable, save advantages such as material, be a desirable wide new type scaffold of safe and reliable usage range in fact.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the latch structure schematic diagram of the utility model;
Fig. 3 is the wheel disc vertical view of the utility model;
Fig. 4 is the wheel disc sectional view of the utility model;
Fig. 5 is the scheme of installation of the utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further.
Among the figure, 1 is montant, 2 is cross bar, 3 is wheel disc, be disposed on vertically on the montant 1, this wheel disc is made of cylinder 31 and the slotting ear 32 that is symmetricly set between the cylinder, the outer wall 34 of cylindrical outer wall 33 and slotting ear all is made as trapezoidal walls, it is latch that three internal faces of slotting ear upper shed 35 are trapezoidal faces 36,4, is made of the voussoir 41 of bottom and the plug 44 on top, the inner face of voussoir 41 is made as the arc surface 42 that matches with montant, its excess-three face is made as trapezoidal faces 43, so as matched with three internal faces 36 of the slotting ear opening 35 of wheel disc, to increase the contact area between them, one side of plug 44 is a concave station 45, so that the end of cross bar 2 is by welding or be spirally connected and place on this concave station, opposite side moves close to somebody's ear 46 for the circular arc that connects with montant, and this width of moving close to somebody's ear is greater than the width of voussoir 41.
Claims (5)
