TH822A - Pipe shape material used to make scaffolding Assembly method And the horizontal cross beam that is assembled into the material used to make the scaffold - Google Patents

Abstract

This invention involved the tube-shaped material used to make the scaffold, the method of assembling the parts. And the horizontal transverse beams assembled in it.The materials used to make the scaffold according to the invention include The vertical part that supports the bolts, where each socket is used to attach the ends of the cross beam along the Lying on the prong support and the internally held conical pin, near the end of the pin, there is a loosely attached spike in the pin. The pin rests in a relatively horizontal position. And the top edge of the socket slightly collides with the back of the spur and causes the peg to rotate vertically.One such invention is the construction of a scaffold for the construction of a ship building or a large water tank.

Claims (2)

1. How to assemble the scaffolding using pipe-shaped materials. Which consists of vertical parts that are installed with a socket Hollow type and consists of horizontally reinforced cross beams comprising at least at the ends of both ends having a prong-shaped assembly composed of a vertical wall. It is attached to one such end perpendicular to the axis of the crossbar. And the upper horizontal wing and one lower wing and one lower wing, each consisting of a channel. The prong has a pin. The cone is fixed in it, it is fixed through a hole in the upper wing, and its body rests relatively horizontally while at rest. Where the peg consists of a pivot that is At least one overhang on the side surface of the pin, the spur is near the narrow end of the pin and The teeth are placed still within the forks. And how to do it Applied in the process of fixing the wings horizontally of the forks of the Prong with such a socket Then relative substitution Of the crossbar used to support the forks vertically relative to the said socket, which will cause the top edge of the socket to be aligned with the bottom edge of the pin to the side The back of the spur slightly and the teeth of the pin to rotate in Vertically and slides down with gravity inside the socket And fixed within the channel in the lower wing. 2. Scaffolding using a pipe-shaped material. It consists of parts. A hollow type socket fixed on the said part and the horizontal reinforced crossbeam consisting of at least one end of the horizontal cross beam. With fixed prongs Pin to any of these sockets Teeth consist of A vertical wall that is attached to at least one such end. And two horizontal wings, the upper horizontal wing consists of the upper slit and the lower horizontal wing consists of the lower slit, the forks support. A cone-shaped pin, which is pinned through a hole in the upper wing when in The position is quite horizontal and stationary. At the said pins It consists of a spur with at least one overhang on the surface. Side of the pin, near the narrow end of the pin And it also opposes the lower surface of the horizontal upper wing, and that the pins are also made up of parts for Adjust pin position While stationary, in a relatively horizontal position, so that when The aforementioned vertical wall of the forks with the said socket, the upper edge of the said socket supports the lower edge of the pivot, slightly towards the back of the spur, and keeps the stud in alignment. Set it up, and slide it down with gravity inside the socket. Said and pinned within the channel in the lower wing 3. Scaffolding as in claim 2, which the pins are assembled With the shoulder part made to fit the inner surface Of such a vertical wall And is the cause of the pin to stop by Prevent the peg from rotating. 4. Scaffolding as in claim 3, where the peg is assembled. With a square notch Which the width of it is longer than The thickness of the vertical wall of the prong and which is fixed on the upper edge Of the wall and formed the back end of the channel in the upper wing 5. Scaffolding as in claim 4 where the upper wing It consists of a right-angled portion that is sliced downward. 6. Scaffolding as in claim 5 at the lower wing of the forehead. Mentioned in front of the channel used as a passage of The peg has a bend with an upward slope that is directed upwards to make it suitable to be used to guide the pin while moving it. 7. Scaffold as in claim 6 at the narrow end of the pin. It is an overhang that is notched, an angle separated by a slope. In such a way that the front of the peg protrudes And which consists of Together with the bent part to bring down the movement of the pins 8. Scaffolding as in claim 6 that the socket consists of The front supports the arms and the two lateral faces that are quite upright. The scene with the support page thereof On the sides of the surface Connected to the aforementioned support by the shaped joints. A bend radius R in the form of R (formula) 2 is either length or equal to the thickness E of the pins. 9. Scaffolding as in claim 7 at the said socket. Consists of the surface on the side of it There is at least one hole. Hole for mounting support material that is connected to the wind 1 0. Scaffolding as in claim 9 where the holes are extended with some notches on the side 1 1. Scaffolding as in claim 9 where the peg consists of the area near the wide end. With holes or channels For the pin to be lifted from a distance 1 2. Scaffolding as in claim 2, where the rear end of The above box In the vertical wall of the prong And the center pin has one narrow end and the other wider, and that narrow end is pinned inside the top slot, and the spur is thicker than the thickness of the slot. The above and less than the thickness of the smaller opening, and the such wide end is wider than the length of the The lower opening for the peg to be confined to the forks and when in the stationary position the peg rest. Is on the top of the crossbar. And the spur will support Against the lower surface of the upper wing (12 claims, 3 faces, 13 photos).
