Composite wooden column structure

Abstract

The utility model belongs to the field of composite wooden columns, and discloses a composite wooden column structure which comprises a column core and a core sleeve. Wherein the core sleeve is tightly arranged on the outer side of the column core in a sleeving mode to provide a restraining effect. The column core adopts a construction mode that multiple layers of vertical plates are sequentially glued and stacked in the transverse direction, and all the vertical plates extend in the vertical direction to bear axial loads. In order to further enhance the lateral thrust resistance of the structure, inserting plates are arranged on the vertical plates, the extending direction of the inserting plates and the extending direction of the vertical plates are arranged in an orthogonal mode, and the inserting plates are inserted and fixed in the mode of penetrating through at least two adjacent vertical plates. The orthogonal cross construction form effectively improves the shear capacity of the composite wooden column in multiple directions, and meanwhile, the stability of the whole structure is further enhanced through the restraining effect of the core sleeve, so that the technical defect that interlayer cracking is prone to occurring when a traditional composite wooden column bears transverse thrust is overcome.

Description

Technical Field

[0001] This utility model belongs to the field of composite wood column technology, and more specifically, it relates to a composite wood column structure. Background Technology

[0002] In existing technologies, composite wood columns are widely used in building structures due to their lightweight, high strength, and environmental friendliness. However, traditional composite wood columns are typically made of multiple layers of plywood or wood materials, and their structural design is mainly optimized for axial compression or tensile loads, giving them good load-bearing capacity in a single direction. However, when the composite wood column is subjected to lateral thrust perpendicular to the plywood stacking direction, the limited bonding strength between the plywood layers makes the interlayer joints prone to cracking or peeling, leading to a decrease in overall structural stability. This problem is particularly prominent when building structures are subjected to multi-directional loads (such as earthquakes, wind loads, and other complex stress conditions), limiting the application of composite wood columns in a wider range of engineering scenarios. Furthermore, the interlayer connection methods of existing composite wood columns usually rely on the adhesive properties, and adhesives may age or weaken under long-term environmental changes or humidity influences, further exacerbating the risk of interlayer cracking. Utility Model Content

[0003] The purpose of this application is to provide a composite wood column structure to solve the technical problem that composite wood columns in the prior art are prone to cracking when subjected to lateral thrust.

[0004] To achieve the above objectives, the technical solution adopted in this application is as follows:

[0005] A composite wooden column structure is provided, including a column core and a core sleeve. The core sleeve is sleeved on the outside of the column core. The column core includes uprights and inserts. The uprights extend vertically and there are multiple uprights. The uprights are stacked sequentially in the transverse direction. The extension direction of the inserts is orthogonal to the extension direction of the uprights, and the inserts are sequentially inserted into at least two uprights.

[0006] As a further improvement to the above technical solution:

[0007] Optionally, there may be multiple insert plates, each of which is inserted into the upright plate.

[0008] Optionally, each of the insert plates is inserted into the upright plate at intervals along the vertical direction.

[0009] Optionally, the insert plate is arranged parallel to the horizontal plane.

[0010] Optionally, the insert plate is set at an angle to the horizontal plane.

[0011] Optionally, the core has a cavity extending vertically and penetrating the core, and each of the insert plates is placed in the cavity in sequence.

[0012] Optionally, the upright plate and / or insert plate are flame-retardant plates.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] The composite timber column structure provided in this application includes a column core and a core sleeve. The core sleeve is tightly fitted onto the outside of the column core to provide restraint. The column core adopts a construction method of multiple layers of vertical panels glued and stacked sequentially in the transverse direction, with each vertical panel extending vertically to bear axial loads. To further enhance the structure's resistance to lateral thrust, insert plates are provided on the vertical panels. The extension direction of these insert plates is orthogonal to the extension direction of the vertical panels, and they are fixed by inserting through at least two adjacent vertical panels. This orthogonal and intersecting construction effectively improves the shear resistance of the composite timber column in multiple directions, while the restraint effect of the core sleeve further enhances the overall structural stability, thereby improving the technical defect of traditional composite timber columns that are prone to interlayer cracking when subjected to lateral thrust.

[0029] To address the technical problem of interlayer cracking in composite wood columns under lateral thrust, such as Figures 1 to 3As shown, this application provides a composite wood column structure, specifically including a column core 1 and a core sleeve 2. The core sleeve 2 is tightly fitted onto the outside of the column core 1 to provide restraint. The column core 1 adopts a construction method of multiple layers of vertical plates 11 glued and stacked sequentially in the transverse direction, with each vertical plate 11 extending vertically to bear axial loads. To further enhance the structure's resistance to lateral thrust, insert plates 12 are provided on the vertical plates 11. The extension direction of the insert plates 12 is orthogonal to the extension direction of the vertical plates 11, and they are fixed by inserting through at least two adjacent vertical plates 11. This orthogonal cross-construction effectively improves the shear resistance of the composite wood column in multiple directions, and at the same time, the restraint effect of the core sleeve 2 further enhances the overall structural stability, thereby improving the technical defect of traditional composite wood columns that are prone to interlayer cracking when subjected to lateral thrust.

[0030] like Figures 1 to 3 As shown in a specific embodiment of this application, the composite wood column structure employs a multi-set arrangement of insert plates 12, each insert plate 12 being horizontally inserted between the upright plates 11. By setting multiple insert plates 12, the interlayer connection strength between the upright plates 11 can be enhanced, effectively preventing interlayer slippage that may occur when subjected to lateral thrust. The cross-connection of each insert plate 12 with the upright plate 11 forms a stable grid-like support structure, significantly improving the composite wood column's resistance to multi-directional thrust while maintaining its axial load-bearing capacity. By adjusting the number and spacing of the insert plates 12, the lateral stiffness and load-bearing capacity of the composite wood column can be flexibly controlled according to actual engineering requirements.

[0031] like Figures 1 to 3 As shown in a specific embodiment of this application, the insert plates 12 are inserted between the upright plates 11 in a vertically spaced arrangement. The insert plates 12 can be arranged in a single or multiple-column array, creating uniformly distributed transverse connection nodes between the upright plates 11. When multiple columns are used, the insert plates 12 in adjacent columns can be staggered vertically to enhance the overall connection between the upright plates 11. This spaced-out arrangement of the insert plates 12 not only ensures the continuity of the composite wood column under axial force but also effectively disperses the influence of transverse thrust on the interlayer bonding surface through the synergistic effect of multiple connection nodes. The number of columns and spacing of the insert plates 12 can be adjusted according to actual stress requirements to achieve optimal structural performance.

[0032] like Figure 3 As shown, in one specific embodiment of this application, the insert plate 12 is arranged parallel to the horizontal plane. This horizontal arrangement can effectively resist lateral thrust in the vertical direction. Figure 4As shown, in another specific embodiment, the insert plate 12 can be arranged at an angle to the horizontal plane, and the range of this angle can be adjusted according to the actual force requirements. The inclined insert plate 12 can not only resist the lateral thrust in the vertical direction, but also withstand the oblique force at the same time, thus forming a multi-directional force system. These two arrangements can be used alone or in combination according to the actual needs of the project. The horizontal arrangement is suitable for working conditions that mainly bear vertical thrust, while the inclined arrangement is suitable for complex force environments that need to resist multi-directional thrust at the same time. By adjusting the angle of the insert plate 12, the stress performance of the composite wood column under different working conditions can be optimized.

[0033] like Figure 5 As shown, in a specific embodiment of this application, the column core 1 is provided with a cavity extending longitudinally through the entire structure, and the extension direction of the cavity is consistent with the axial direction of the column core 1. The insert plates 12 are arranged sequentially in a stacked manner and fixed inside the cavity, forming a stable lateral support system. By providing a cavity in the column core 1, the integrity of the column core 1 can be ensured, and installation and positioning space for the insert plates 12 can be provided, effectively enhancing the structural stability of the composite wood column under multi-directional loads. By controlling the size and shape of the cavity, the arrangement density and connection effect of the insert plates 12 can be optimized, thereby adjusting the mechanical properties of the composite wood column according to actual engineering needs.

[0034] In one specific embodiment of this application, the materials for the upright plate 11 and the insert plate 12 include, but are not limited to, oriented strand board (OSB) or oriented strand board with fire retardant. When OSB is used as the substrate, its longitudinally arranged wood fiber structure effectively improves the compressive strength of the upright plate 11 under axial stress, while the transverse fiber distribution of the insert plate 12 enhances the shear resistance of the interlayer connection. When oriented strand board with fire retardant is selected, the fire safety performance of the composite wood column is further improved while maintaining the original mechanical properties. This material selection scheme ensures the mechanical strength of the structural components and meets the requirements of building fire protection codes, and can be flexibly configured according to the needs of specific application scenarios. The anisotropic characteristics of oriented strand board match the multi-directional stress characteristics of the composite wood column, achieving an optimal combination of material performance and structural function.

[0035] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
