Inserting connection type single-layer aluminum alloy reticulated shell connection joint
The invention discloses an inserting connection type single-layer aluminum alloy reticulated shell connection joint. The inserting connection type single-layer aluminum alloy reticulated shell connection joint comprises aluminum alloy rod pieces, an upper circular cover plate, a lower circular cover plate, a wedge block and shearing resisting connection plates; the wedge block is arranged betweenthe upper circular cover plate and the lower circular cover plate, and the center line of the wedge block in the length direction coincides with the center lines of the upper circular cover plate andthe lower circular cover plate; the wedge block is provided with T-shaped hole grooves in the radial pattern, and the shearing resisting connection plates are in a T shape; one end of each shearing resisting connection plate is provided with a wing edge small in width to be inserted into the corresponding hole groove of the wedge block; the shearing resisting connection plates and the wedge blockare connected in a mechanical engaging manner; the other ends of the shearing resisting connection plates and web plates of the aluminum alloy rod pieces are connected through stainless steel bolts; and upper and lower wing edges of the aluminum alloy rod pieces and the upper and lower circular cover plates are connected through stainless steel bolts. Due to the inserting connection type single-layer aluminum alloy reticulated shell connection joint, the bending resisting and shearing resisting bearing force of the joint is remarkably enhanced, the rigidity of the joint and the overall stability of a reticulated shell are improved, and therefore application to a single-layer aluminum alloy reticulated shell structure larger in span can be achieved.
本发明公开了一种插接式单层铝合金网壳连接节点，包括铝合金杆件、上圆形盖板、下圆形盖板、楔块和抗剪连接板；楔块竖直设在上、下圆形盖板之间，楔块沿长度方向的中心线分别与上、下圆形盖板中心线重合，楔块开设放射状的T形孔槽，抗剪连接板呈T形，抗剪连接板一端带有宽度较小的翼缘插入楔块的孔槽内，抗剪连接板与楔块通过机械咬合连接，抗剪连接板另一端与铝合金杆件的腹板通过不锈钢螺栓连接；铝合金杆件的上下翼缘分别与上、下圆形盖板用不锈钢螺栓连接，本发明显著增强了节点的抗弯和抗剪承载力，提高了节点的刚度及网壳的整体稳定性，从而可应用于更大跨度的单层铝合金网壳结构。
