Abstract

The utility model discloses a cross bar joint for a daisy fastening type scaffold, which is provided with a base, wherein one side of the base extends, forming two tong rams; the other side of the base extends, forming a plug. A daisy-shaped buckle disc plane leading-in channel is formed between the two tong rams, and each of the tong rams is provided with a slot bore for a bolt to insert. The maximal span of the two tong rams is 70 millimeters. The distance between the plane of the other side of the base and the vertical center surface of a connection structure of a daisy fastening type is 72.5 millimeters. Through adopting the structure, the utility model causes a cross bar plug to be convenient for the connection between the daisy-shaped buckle disc and the bolt, and an interpenetration self-locking mechanism is safer, which is more favorable for the production, the transportation, the field installation and the disassembly of a daisy fastening type scaffold.

Description

Chrysanthemum button scaffold cross bar joint

Technical field

The utility model relates to scaffold member, is specifically related to a kind of chrysanthemum button scaffold cross bar joint.

Background technology

Chrysanthemum button scaffold is the upgraded product of bowl fastening type scaffold, the template that is applicable to highrise building, common building, overpass bridge, bridge, tunnel supports and effluxes grid, also be applicable to span frame and indoor and outdoor decoration engineering, adopted by vast building unit.As shown in Figure 1 and Figure 2, the agent structure of this chrysanthemum button scaffold is that the cosmos button dish 1 that will have four cross bar lockholes 11 and four diagonal member lockholes 12 is welded in the vertical rod 4, cross bar 5 two ends welding cross bar plug 2.And the structure of above-mentioned cross bar plug 2 such as Fig. 3, Fig. 4 and shown in Figure 5, it has a pedestal 21, pedestal one side extend two tong arms 22 and pedestal opposite side extend one with affixed plug 23, two tong arms 22 of cross bar between form and offer the slotted eye 25 that inserts for latch on cosmos button dish introduction channel 24 and each tong arm.During installation, earlier the dish introduction channel 24 of buckleing on the cross bar plug 2 is aimed at cosmos and buckled cross bar lockhole 11 positions on the dish 1 and push cosmos and buckle dish 1 plane and cause the tong arm distal side and hold out against vertical rod 4 and end, with hand latch 3 is inserted lockhole and the slotted eye on another tong arm of plug passes through the slotted eye on plug one tong arm then, strike tightly with hand hammer more just cross bar and vertical rod to be connected together securely.

The scaffold of said structure has following characteristics: 1, multi-functional: according to concrete construction requirement, modulus can be formed and be the construction equipment of the multiple function such as single, double-pole scaffold, bracing frame, bracing frame, support column, material hoisting frame of the multiple group of frame size of 0.6m and load, and arrangement of curves can be done; 2, effect height: piece together the speed of tearing open fast 0.5 times than bowl fastening type scaffold; 3, lightly easy: the bowl button vertical rod of chrysanthemum button vertical rod weight ratio equal length specification reduces 6-9%; 4, supporting capacity is big: the chrysanthemum dish is buckled dish and is had shearing resistance reliably axially, and various center line of the bar meets at a bit, connects cross bar quantity and has more 1 times than a bowl snapping head, and monolithic stability intensity is improved 20% by bowl button and scaffold; 5, safe and reliable: adopt independent chock to intert self-locking mechanism, because interlocking and action of gravity, even latch is not struck tightly, the cross bar plug also can't be deviate from; 6, comprehensive benefit is good: the no scattered member of easily losing, and loss is low, and transportation and management are convenient in the later stage less investment.

Summary of the invention

The purpose of this utility model is the practical situations in conjunction with existing chrysanthemum button scaffold, a kind of chrysanthemum button scaffold cross bar plug is provided, some dimensional standardization that it makes the cross bar plug, install at manufacturing, transportation and the scene that is more conducive to chrysanthemum button scaffold, dismounting.

The technical solution of the utility model is as follows: chrysanthemum button scaffold cross bar joint, one pedestal is arranged, pedestal one side extends two tong arms and the pedestal opposite side extends a plug, forms between two tong arms and offers the slotted eye that inserts for latch on cosmos button dish plane introduction channel and each tong arm; The maximum span of described two tong arms is 70 millimeters, and the distance that reaches the vertical central plane of pedestal opposite side plane of living in and chrysanthemum button syndeton is 72.5 millimeters.

The lateral surface that the confession latch of each tong arm inserts is made up of the inclined-plane that the plane and of setting straggly about in the of two is connected between two planes, and the width on last plane is 14.6 millimeters, and the projection width on inclined-plane is 9 millimeters, and the width of lower plane is 21.1 millimeters.

The distal side of each tong arm forms a boss, and the end face of this boss is the length and the wide cambered surface that is 16 millimeters of a plane of projection, and this cambered surface radius is 14.721 millimeters.

The utility model makes the cross bar plug be convenient to buckle being connected between dish and the latch with cosmos by adopting said structure, makes interspersed self-locking mechanism safer, is more conducive to manufacturing, transportation and on-the-spot installation, the dismounting of chrysanthemum button scaffold.
