Detailed Description
Example 1
As shown in fig. 1 to 6, the building template connecting piece comprises a vertical rod piece 1 and a horizontal rod piece 3. The two rod pieces are round steel pipes and serve as supporting frames, a slot disc 2 is fixed on the vertical rod piece 1, the slot disc 2 is a round steel piece, the slot disc 2 is sleeved and welded on the vertical rod piece, four through holes 21 are uniformly distributed in the circumferential direction of the slot disc, the through holes are square holes, and one side face of the through holes is an inclined face 22. In order to lighten dead weight, a diagonal bar plug hole 23 is arranged between two adjacent through holes of the slot disc, and the included angle between the diagonal bar plug hole and the through holes is 45 degrees.
One end of the cross rod member 3 is inserted into a positioning hole 41 at the upper end of the plug-in unit 4, and is firmly welded to form a whole, the lower end of the plug-in unit 4 is a wedge-shaped body 42 matched with the through hole, and one side of the upper part of the plug-in unit matched with the vertical rod member is an arc-shaped body 44. And a rectangular groove 43 is formed on the wedge-shaped surface of the plug-in unit, an eccentric self-locking block 5 is pivoted in the groove through a round pin, and the plug-in unit can be clamped in the through hole of the slot disc after the self-locking block 5 passes through the through hole and is provided with a saw tooth 51 for auxiliary self locking.
The installation method comprises the following steps: the plug-in 4 wedge-shaped body plug on the cross rod welding component is inserted into the disc square hole of the slot disc 2 of the vertical rod under the action of external force, the taper under the plug-in is matched with the taper on one side of the disc through hole under the action of hammer strike, and finally, the arc on the upper part of the plug-in is more and more tightly jointed with the outer surface of the vertical steel tube, so that the first self-locking is realized. After the self-locking block mechanism is added, the saw teeth and the disc in the self-locking disc are clamped by utilizing the principle that the self-locking block is drooping due to the eccentric dead weight, so that secondary self-locking is realized, and the plug can be effectively prevented from being pulled out.
When the self-locking block is disassembled, the upper right end of the self-locking block is knocked by a hammer, as shown by an arrow in fig. 1, the self-locking block is quickly returned and pulled out upwards forcefully, and the disassembly is easily realized.
Example two
As another embodiment, as shown in fig. 7 to 9, a difference from the first embodiment is that a U-shaped card 6 is horizontally inserted into the socket plate 2 at the diagonal draw bar plug hole 23, and the U-shaped card 6 is integrally formed with both ends of the diagonal draw bar. A socket 61 communicated with the inclined rod plug hole is formed in the vertical direction of the U-shaped clamp, and a wedge-shaped locking pin 62 is inserted into the socket 61, so that a transverse positioning pin 63 can be added at the bottom of the locking pin to prevent the locking pin from loosening, and the locking pin is fixed to prevent falling.
Various combinations of diagonal braces 7 attached to the U-shaped card are possible, such as the one shown in fig. 9.
Other than the technical features described in the specification, all are known to those skilled in the art.
