Technical Field

[0001] The utility model belongs to the technical field of wood structure buildings, and in particular relates to a lattice column top connection structure. Background Art

[0002] In the context of "double carbon", as energy-saving and environmentally friendly green buildings, wooden structures are increasingly used. However, due to the size of the logs themselves, the cross-sectional size of the wood used for wooden structures is also limited. The production and manufacturing of wood with small cross-sectional sizes is relatively easy and has a higher utilization rate of logs. How to use small cross-sectional wood more widely and flexibly is a problem that exists today.

[0003] Different sizes of wooden structures require different cross-sections of wood. At present, wooden structures are mainly made of wood of the required size. The utilization rate of wood with smaller cross-sections is low, resulting in a waste of resources. Utility Model Content

[0004] The utility model aims to provide a lattice column top connection structure to solve the problem of low utilization rate of wood with smaller cross-sections, which leads to waste of resources.

[0005] To achieve the above-mentioned object, the utility model provides the following technical solutions: a lattice column top connection structure, comprising a central column and a metal connecting piece, wherein the metal connecting pieces are four, the four metal connecting pieces are all fixedly connected to the outer wall of the central column, and are symmetrically arranged in pairs with respect to the central column, the central column is provided with a top cover, and the metal connecting piece is fixedly connected to the top cover;

[0006] The metal connecting piece is symmetrically bent 90 degrees to one side with the middle as a fixed point to form a "C" shape. The "C"-shaped port of the metal connecting piece is fixedly connected to the outer wall of the center column. The top cover is fixedly installed at the axis of the center column and vertically connected to it. The side adjacent to the "C"-shaped port of the metal connecting piece is fixedly connected to the top cover.

[0007] Preferably, the central column is a rectangular hollow tube.

[0008] Preferably, threaded holes are provided on the outer walls on opposite sides of the metal connecting piece.

[0009] The technical effects and advantages of the utility model are as follows: the wooden columns are fixed respectively by two adjacent metal connecting pieces, so that four small-section wooden columns are connected as a whole and used as a large-section wooden column, so as to improve the utilization rate of small-section wood, facilitate the related application and design of small-area wood, and connect multiple small-section woods into a larger-section wood through the metal connecting piece and the central column, which does not affect the actual use, improves the utilization rate of wood and reduces waste.
