Description

Technical Field

[0001] The invention relates to a cabinet combining steel and solid wood, which is connected by mortise and tenon joints. Background Art

[0002] Museums such as the Forbidden City preserve valuable cultural relics and handicrafts, and there are clear earthquake-resistant requirements for the shelves or cabinets used to display these cultural relics and handicrafts to prevent them from being damaged by vibration or being smashed by collapsed buildings during earthquakes. Therefore, they are generally made of metals such as steel.

[0003] However, whether it is a cultural relic or a handicraft, in addition to its high value, it usually also has artistic and cultural attributes. Therefore, the preservation unit hopes that the cabinets for preserving such cultural relics and handicrafts are artistic or follow Chinese traditional culture. The hard and cold characteristics of metal are difficult to meet the requirements of relevant units and personnel for proper storage.

[0004] Relevant experts have proposed using traditional Chinese solid wood furniture to give it the connotation of Chinese civilization. However, solid wood furniture is difficult to meet earthquake resistance requirements.

[0005] In view of this, the present invention is proposed. Summary of the Invention

[0006] The purpose of the present invention is to provide a mortise and tenon joint cabinet combining steel and solid wood, so as to combine the advantages of steel and solid wood furniture and meet the needs of institutions such as museums.

[0007] The mortise and tenon joint cabinet combining steel and solid wood of the present invention comprises a steel rack, a solid wood cabinet body covering the outer side of the steel rack and the steel rack inside, and the solid wood cabinet body and the steel rack are connected together through a mortise and tenon structure.

[0008] The mortise and tenon structure includes dovetail mortises on a solid wood cabinet body and dovetail tenons on a steel storage rack, wherein the dovetail tenons are inserted into the mortises of the solid wood cabinet body.

[0009] In order to facilitate installation, the dovetail mortise on the solid wood cabinet body adopts a vertical long groove with a dovetail-shaped horizontal cross-section, and the width of the lower end of the long groove is not less than the maximum width of the dovetail tenon to form an insertion port.

[0010] The dovetail joint is a steel dovetail block welded on the side of the steel storage rack.

[0011] The dovetail tenon is a dovetail head screw that is threadedly mounted on the side of the steel storage rack.

[0012] The mortise holes can be arranged on the mountain boards on both sides of the solid wood cabinet body, and are preferably arranged on the columns at the four corners of the solid wood cabinet body.

[0013] The steel storage rack is provided with a push-pull type storage shelf via a slide rail.

[0014] Preferably, the horizontal width of the lower end of the mortise is not less than the maximum width of the dovetail tenon.

[0015] The present invention's mortise and tenon-jointed steel and solid wood cabinet features a solid wood cabinet body to meet aesthetic requirements. The traditional mortise and tenon structure and craftsmanship of the solid wood cabinet body, incorporating traditional cultural elements, can also be carved or hollowed out. The interior steel shelves meet the seismic requirements of cultural relic preservation. The solid wood cabinet body and steel shelves are connected by the mortise and tenon structure, forming a single unit. This further enhances the connection strength of the solid wood cabinet body, prevents deformation of the solid wood cabinet body, and strengthens the overall seismic performance.

[0025] The present invention will be further described below with reference to the accompanying drawings and specific embodiments to facilitate understanding of the present invention.

[0026] Example 1

[0027] like Figure 1 、 2 Figures 4 and 5 are schematic diagrams of the present invention's mortise-and-tenon-jointed steel and wood cabinet. The interior features a steel shelf for storing artifacts and providing compressive and seismic resistance. A solid wood cabinet body covers the steel shelf, enclosing the steel shelf within. To enhance compressive and seismic resistance, both the steel shelf and the solid wood cabinet body rest directly on the ground via their own legs. This means the solid wood cabinet body lacks a bottom plate, and the bottom of the steel shelf is not supported by the solid wood cabinet body. This is crucial for enhancing the compressive and seismic resistance of the entire combined cabinet.

[0028] The solid wood cabinet body consists of four corner columns 10, two double-leaf cabinet doors (can be opened 180 degrees) 13 installed on the front through four pairs of hinges 12, and a frame structure formed by vertical beams 14 and a "cross"-shaped horizontal beam on both sides, as well as the upper and lower horizontal beams and the front and rear columns 10 through mortise and tenon structures. In the middle, there are side panels 11 inserted into the slots of the frame structure through the four sides to form the two sides of the solid wood cabinet body. Figure 4 As shown, there is a back panel inserted into the slot formed by the solid wood frame to form the back of the solid wood cabinet, and a top panel on the top. Figure 4 and Figure 5 As shown, mortises are machined on the side panels on both sides, and the horizontal cross-section of the mortises is as follows: Figure 4 The dovetail shape is shown, as Figure 5 The horizontal width of the lower end of the mortise is slightly larger than the maximum width of the dovetail tenon, so that the dovetail tenon 27 on the steel shelf can be inserted into the mortise from this end, and the insertion becomes tighter and tighter.

[0029] like Figure 3 As shown, the steel storage rack is composed of stainless steel vertical square tubes 21 and horizontal square tubes 20 welded together into a cubic frame. A fixed horizontal shelf 22 is located in the center, along with sliding shelves 23 mounted on rails 26. The sliding shelves 23 are used to store large and heavy artifacts. The shelves 23 are double-layered and can be pulled out, with the top shelf removed for easy access. The lower portion is formed by four vertical square tubes 21 at the corners, forming the legs that rest on the ground. Four dovetail vertebrae 27 are welded to each side of the vertical square tubes 21 on each side of the steel storage rack.

[0030] A front baffle 24 and a handle 25 are provided at the front of the push-pull shelf 23. The front baffle 24 prevents the cultural relics thereon from falling during the pushing and pulling process, and the handle 25 facilitates manual picking operation.

[0031] like Figure 4As shown, the dovetail tenon 27 of the steel shelf is embedded in the mortise of the dovetail structure in the side panels 11 on both sides of the solid wood cabinet body, and the two sides of the solid wood cabinet are embedded in the two sides of the steel shelf. The steel shelf with good strength and non-deformation properties is used to pull the side panels on both sides of the solid wood cabinet body inward, thereby realizing the assembly and connection of the solid wood cabinet and the steel shelf.

[0032] use Figure 5 The beneficial effects of the mortise and tenon structure shown are: (1) it is easy to install, and the four mortise and tenon holes on the side panels 11 on both sides of the solid wood cabinet assembled by the mortise and tenon structure are as follows: Figure 8 As shown, align the dovetail tenon 27 with the maximum width position of the lower end of the mortise, and at the same time assemble the top and bottom horizontal crossbeams and the back panel of the solid wood cabinet together through the mortise and tenon structure and slots, and then press the side mountain down to Figure 9 As shown, install the side panels of the solid wood cabinet to the sides of the steel rack until the lower part of the side panel reaches the ground. Install the side panels on both sides of the solid wood cabinet to the sides of the steel rack, and then install the cabinet doors on the top and front of the solid wood cabinet. This not only assembles the solid wood cabinet body and the steel rack together, but also covers the steel rack with the solid wood cabinet. (2) The solid wood cabinet and the steel rack stand on the ground with their own legs. The weight of the solid wood cabinet body is not on the steel rack, nor is the weight of the steel rack on the solid wood cabinet body. The two cannot move relative to each other in the horizontal direction, but they can move relative to each other up and down to a certain extent. This is very beneficial for resisting compressive damage during earthquakes and damage caused by ground cracking, swaying, and wave-like deformation.

[0033] The mortise and tenon joint cabinet combining steel and solid wood in this embodiment was subjected to a simulated earthquake resistance test on a vibration test bench. A set of typical natural earthquake accelerations were used to record the dual components X (east-west) and Y (north-south), with specific waveforms being the Wenchuan Wolong wave and the Taft wave. A set of artificially synthesized accelerations was also used to record the dual components X (east-west) and Y (north-south), with specific spectrum and amplitude requirements: PGA: 0.1g, 0.2g, 0.3g, 0.4g, 0.62g; frequency bandwidth: 0.1-40Hz. A standard three-axis accelerometer was used, and one three-axis accelerometer was arranged on the vibration table surface and the mortise and tenon connection cabinet combining steel and solid wood. The seismic test results are as follows: under three waveforms of seismic motion input vibration (peak acceleration of 0.1g, 0.2g, 0.3g, 0.4g, and 0.62g (a rare earthquake of magnitude 9)), the overall appearance of the mortise and tenon connection cabinet combining steel and solid wood was complete, with no deformation or damage to the cabinet doors, side panels, and top panels, the ground connection was normal, and the internal frame, partitions, and shelves were intact and without deformation, meeting the requirements for seismic protection.

[0034] The solid wood cabinet can utilize traditional solid wood furniture craftsmanship, such as rosewood and carved designs. This aesthetically pleasing design also incorporates Chinese cultural elements, fitting the Chinese aesthetic of Chinese cultural relics. However, solid wood is particularly susceptible to deformation during long-term storage, which can cause the mortise and tenon joints in the cabinet to loosen. The steel rack of the present invention not only resists pressure, protecting cultural relics, but also tightens the solid wood cabinet to resist deformation. Furthermore, the solid wood cabinet provides primary compressive strength and protects the steel rack and the cultural relics it contains.

[0035] Example 2

[0036] like Figure 6 As shown, in the mortise and tenon connection cabinet combining steel and solid wood in this embodiment, the dovetail tenons 27 on the steel storage rack are located on the vertical square tubes 21 at the four corners, and the corresponding mortises are located on the columns 10 at the four corners of the solid wood cabinet body. That is, the steel storage rack connects the four main load-bearing columns 10 of the solid wood cabinet body together through dovetail tenons. Not only is the overall structural property better than that of Example 1, but also because the thickness of the column is greater than the thickness of the side mountain board, it is conducive to increasing the size of the mortise and dovetail tenon and ensuring the connection strength. Therefore, its seismic performance is better, and the mortise and tenon structure of the solid wood cabinet itself is less likely to loosen and deform.

[0037] The dovetail joint used in this embodiment is not welded to the vertical square tube 21, but is Figure 7 As shown, dovetail tenons 27 are dovetail screws threadedly mounted on the side of the steel rack. To further secure the connection, metal, engineering plastic, or solid wood modules 28 with threaded holes are inserted into the vertical steel tubes 21. Compared to the welding method in Example 1, the dovetail tenons can be installed with greater precision due to the use of machining rather than welding.
