Description

Technical Field

In the actual use process of the cantilever beam structure, it often has to bear various concentrated loads, distributed loads, bending moments and torques, and large stresses and deformations may occur at any point of the beam, thus causing the cantilever beam structure to be damaged or fail. When the load is relatively large, a fulcrum needs to be added under the free end of a common cantilever beam with a span exceeding 5 meters to increase the load-bearing capacity of the cantilever beam. Adding a fulcrum is time-consuming and laborious, and the ground space of some sites is limited and does not allow adding a fulcrum.

A plurality of connecting cross rods 13 and connecting diagonal rods 14 are arranged between two adjacent vertical columns 11, so that the four columns form a stable support system.

[0035] In this embodiment, one end of the support beam 2 is detachably clamped on the vertical column 11 of the four-corner column 1 close to the support beam 2 through an outrigger connector 4, and the other end projects outwards from the four-corner column 1; the outrigger connector 4 includes a beam connecting plate 41 fixedly connected to the end of the support beam 2, one end of the beam connecting plate 41 is provided with a connecting vertical plate 42 perpendicular to the beam connecting plate 41, and two wedge mechanisms 43 for clamping on the chrysanthemum buckles 12 of the vertical column 11 are arranged on one side of the connecting vertical plate 42 close to the vertical column 11. The wedge mechanism 43 adopts a design of a movable bolt. During assembly, first pull up the bolt to make the chrysanthemum buckle 12 on the vertical column 11 embed into the wedge mechanism 43, and then put down the bolt to make it pass through the clamping interface 121 of the chrysanthemum buckle 12. When it is necessary to adjust the height of the support beam 2, only need to clamp the wedge mechanism 43 of the outrigger connector 4 on the chrysanthemum buckle 12 at the corresponding height of the vertical column 11, and at the same time adjust the connection position between the support twin diagonal rods 3 and the support beam 2, and the operation is simple and fast.

[0036] In order to adjust the connection position between the supporting double diagonal rods 3 and the supporting cross beam 2 so that a triangular structure is always formed among the supporting double diagonal rods 3, the supporting cross beam 2 and the four-corner columns 1, a plurality of adjustable holes 21 are provided on both side surfaces of the supporting cross beam 2, and a plurality of cross beam adapters 5 detachably installed on the adjustable holes 21.
