Problems solved by technology

[0007] In view of the problems that the existing mechanical properties of the beam and column ends are damaged when the existing bamboo-wood structure beam and column connectors are anchored, it is not easy to disassemble and recycle later, the local stress is too concentrated, and the height and span of the bamboo-wood structure are restricted. The invention provides an assembled bamboo-wood beam column and its connectors, a disassembly method and a bamboo-wood structure node

Embodiment 1

[0058] Such as figure 1 with figure 2 As shown, the beam-column connector of the present invention includes a central piece 1, a column end piece 2 and a connecting piece 7, the column end piece 2 is nested in the central piece 1, and the central piece 1 and the column end piece 2 are fixed by the connecting piece 7 . The beam-column connector of the embodiment of the present invention is introduced in detail below: the center piece 1 includes a center piece casing 11, a center piece base plate 12, a center piece upper fin 13 and a center piece lower fin 14, and the center piece casing 11 is arranged on Above the centerpiece substrate 12, the cross-sectional shape of the centerpiece casing 11 is not limited to figure 1 The rectangle shown in , can also be circular, elliptical, polygonal or other irregular shapes, but no matter how the cross-sectional shape of the center piece casing 11 changes, as long as it can ensure that it is consistent with the column end pieces desc...

Embodiment 2

[0067] On the basis of Embodiment 1, the cross-section of the center piece casing 11 is still rectangular, and the difference with Embodiment 1 is that the four sides of the center piece casing 11 are not all provided with a The upper fins 13 of the center piece are assembled, but only a set of upper fins 13 of the center piece are respectively arranged on the two opposite sides. The center piece 1 designed in this way is more suitable for the outermost layer of the bamboo-wood structure node; , only the upper fins 13 of the center piece are provided on the two adjacent side surfaces of the center piece casing 11, and the center piece 1 designed in this way is more suitable for the edge of the bamboo-wood structure node. Flexible adjustment of the setting position of the fins 13 on the center piece can reduce the processing cost of the center piece 1 and further reduce the construction cost.

Embodiment 3

[0069] On the basis of Embodiment 1, the difference from Embodiment 1 is that the connecting hole 6 is a rectangular through hole with a square cross section, and a groove is arranged on each side of the inner wall of the rectangular through hole. The grooves are arranged and distributed along the circumferential direction of the rectangular through hole, and extend toward the axial direction of the rectangular through hole. In order to make the connection and fixation of the connecting piece 7 better, the connecting piece 7 is now a cross section that matches the rectangular through hole It is a rectangular rod, and each side of the rectangular rod is correspondingly provided with a protrusion matching the groove.

Abstract

The invention discloses a bamboo-wood assembled beam column and its connector, a disassembly method and a bamboo-wood structure node, belonging to the field of bamboo-wood structure connectors. The beam-column connector includes a center piece, a column end piece and a connector, and the center The piece includes the center piece body, the center piece base plate, the center piece upper fin and the center piece lower fin; the column end piece includes the column end piece inlay, the column end piece base plate and the column end piece fin, and the column end piece inlay set Under the base plate of the column end piece, and the inlay of the column end piece is matched with the cover of the center piece; the fins of the column end piece are arranged above the base plate of the column end piece; , The lower fins of the center piece and the fins of the column end pieces are provided with connecting holes, and the connecting holes and the connecting pieces are matched to make the beam-column structural members precisely integrate the force, and reduce the impact of the deformation of the upper part of the bamboo-wood structure on the lower structure. impact, thereby improving the overall structural performance of the house.

Description

technical field [0001] The invention belongs to the field of bamboo-wood structure connectors, and in particular relates to an assembled bamboo-wood beam and column and its connectors, a disassembly method and a bamboo-wood structure node. Background technique [0002] At present, the connecting parts of bamboo and wood structures include nails, bolts, tooth plates, split rings, shear plates, hooks, etc. These connecting parts need to destroy the structure of bamboo and wood itself when used, thus affecting the mechanics of bamboo and wood building structures performance, reducing the stability of the bamboo-wood structure. In addition, these connectors cannot be disassembled and reused, which will cause a lot of waste for the bamboo-wood structure buildings that are only temporarily used and need to be modified later. [0003] The publication number is CN106320535A, and the publication date is January 11, 2017. The Chinese invention patent discloses a beam-column connector,...
