The whole bump 6 is of a wedge-shaped structure (the upper end is small, the lower end is large), and two side surfaces, close to the vertical rod 1, of the bump 6 are concave surfaces 61 formed by inclining from outside to inside;
the boss 2 is provided with a slot 21 (the lower end opening is large, the upper end opening is small) matched with the shape of the lug 6, and two side surfaces of the slot 21 are expansion surfaces 22 formed by the inward and outward inclination of the slot 21;
the lug 6 is fixedly inserted into the slot 21, the horizontal rod can be fixedly connected with the vertical rod 1 under the action of self gravity, and the lower concave surface 61 is in contact with the expansion surface 22 to form self-locking of the horizontal rod and the vertical rod 1 in the horizontal direction.
The peripheral protection scaffold connecting structure of the embodiment further comprises a right-angle fastener 4 used at the connecting part of the horizontal rod and the vertical rod 1; the right-angle fastener 4 is fastened on the vertical rod 1, and the lower end surface of the right-angle fastener 4 is abutted against the end part of the horizontal rod (not shown in the figure). In particular, the right-angle fastener 4 (see page 2 of figure 1 of GB15831-2006 steel tube scaffold fastener) is shown.
The horizontal pole includes vertical horizontal pole 5 and horizontal pole 3, boss 2 set firmly in the tip of being connected of vertical horizontal pole 5, right angle fastener 4 set firmly in on the horizontal pole 3. In practice, the arrangement of the longitudinal horizontal rods 5 and the transverse horizontal rods 3 can be referred to in the technical safety standards of construction fastener type steel pipe scaffolds (JGJ 130-.
The peripheral protection scaffold connecting structure of the embodiment further comprises a sleeve (not shown in the figure) with an opening at one end, the boss 2 is fixed on the end face of the closed end of the sleeve, and the open end of the sleeve is connected with the connecting end of the horizontal rod through threads. When the device is implemented, the open end of the sleeve and the connecting end of the horizontal rod can be connected with the internal thread of the open end through the external thread of the connecting end; or the open end of the sleeve and the connecting end of the horizontal rod can be connected with the external thread of the open end through the internal thread of the connecting end.
The peripheral protection scaffold connecting structure of the embodiment also comprises another type of vertical rods,
the number of the convex blocks 6 on the vertical rod 1 is three, and the convex blocks are uniformly distributed within the range of 180-degree included angles in the circumferential direction (as shown in fig. 4). Such a pole is suitable for use in the transition of scaffolding.
When the peripheral protection scaffold connecting structure of the embodiment is used, the boss arranged at the end part of the longitudinal horizontal rod 5 can be quickly inserted and fixed onto the convex block 6 of the vertical rod 1. And then, after the lower end of the right-angle fastener 4 is used for pressing the longitudinal horizontal rods 5 at the two sides of the vertical rod 1, one locking bolt on the right-angle fastener 4 is screwed, and then the connection of the joint is completed. It can be seen that the application of the peripheral protection scaffold connecting structure of the embodiment can ensure that the longitudinal horizontal rods 5 and the vertical rods 1 can be reliably and fixedly connected while the scaffold can be quickly erected. Is worth popularizing in the field.
Example 2 (not shown in the figure):
the difference from the embodiment 1 is that the boss 2 is only vertically fixed on the vertical rod 1, and the convex block 6 is only vertically fixed on the horizontal rod. In this way, the aim of quickly building the scaffold can be achieved. At this time, the slot 21 on the boss 2 has a large opening at the upper end and a small opening at the lower end; the corresponding convex block 6 is a wedge-shaped structure with a large upper end and a small lower end.

Such a pole is suitable for use in the transition of scaffolding.
In addition, in the two embodiments, since the longitudinal horizontal rod 5 and the vertical rod 1 are connected through the convex block 6 and the convex block 2, the force of the longitudinal horizontal rod 5 can be directly applied to the vertical rod 1, and there is no eccentricity of the fastener-type scaffold at the connection node due to the connection by the fastener, which further results in the transmission of load and internal force by the anti-sliding force, and thus the bearing capacity is reduced. In addition, the connection quality of the connecting node of the fastener type scaffold is not influenced by the quality of the fastener and the operation of workers obviously.
In the two embodiments, the joint has reliable mechanical properties of bending resistance, shearing resistance and torsion resistance. And the axial leads of the rod pieces intersect at a point, so that the scaffold built by the rod pieces has stable and reliable structure and large bearing capacity.
The above is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, several changes and modifications can be made without departing from the technical solution, and the technical solution of the changes and modifications should be considered as falling within the protection scope of the present application.
