Description

Technical Field

[0001] The invention relates to the technical field of yurt construction, in particular to an assembled mortise and tenon type yurt. Background Art

[0002] The yurt is a house built by nomadic people living on the prairie in the process of fighting and blending with the natural environment. In order to adapt to animal husbandry production and nomadic life, the construction and relocation of the yurt are very convenient. The lower part of the yurt is a thick cylindrical shape, and the upper part is a cone shape. The main frame of the traditional yurt includes Taonao, Uni, Khana and door; Taonao in the main frame of the yurt is equivalent to a skylight, located at the top of the yurt, and has the functions of ventilation, lighting and smoke exhaust; Uni is composed of multiple Uni poles to form an umbrella-shaped structure, supporting Taonao upward and relying on Khana downward; Khana is equivalent to a wall, which is a mesh curtain wall supporting the entire yurt. Because Khana is in a mesh shape, the Khana wall can be retracted and the height of the wall can be adjusted according to different needs. When building a yurt in the summer and autumn when there is more rain, Khana is generally built higher, so that the space inside the yurt is larger, which can avoid moisture gathering. The umbrella-shaped Uni on the top of the yurt is also built higher to increase the slope to ensure that water can be discharged quickly when it rains. When building a yurt in the winter and spring when there is strong wind and sand and the temperature drops sharply, the Khanaza is low and the space inside is small, which can maintain the internal temperature and reduce wind resistance, thereby enhancing its stability.

[0003] The main frame of the traditional yurt, including the pottery, uni, khana and door, are all made of wood, and the mortise and tenon structure is a very unique connection method in traditional woodworking buildings. It has a long history and embodies rich cultural connotations and wisdom. The connection method of the mortise and tenon structure is semi-rigid and has certain tensile, compressive, bending and torsion resistance. Therefore, it is suitable for the connection of the main structure of the yurt, which can further enhance the tensile and compressive resistance of the yurt, improve stability, and is easy to build, which is suitable for the needs of nomadic peoples for convenient construction.

[0004] In the current prior art, the mortise and tenon structure has been widely used in the construction of yurts. For example, the connection of the main frame of the yurt in the authorized patents with publication number CN109372285B and publication number CN212926464U both adopts an assembled mortise and tenon structure. In the mortise and tenon structures disclosed in the above two authorized patents and other conventional mortise and tenon structures in the prior art, the protruding tenon and the recessed mortise need to be precisely connected, so the relative positions of the two are fixed. In the actual construction of traditional yurts, due to the above reasons, the slope of the unipole needs to be adjusted according to the climatic conditions of different seasons. Therefore, the relative position of the connection between the unipole and the Khana also needs to be adaptively adjusted as the slope of the unipole changes. If the conventional mortise and tenon structure is adopted at the connection between the unipole and the Khana, it cannot meet the demand for adjusting the slope of the unipole well. Summary of the invention

[0005] The purpose of the present invention is to overcome the problems in the prior art and to provide a mortise and tenon assembled yurt. The connection between the uni pole and the hana of the mortise and tenon assembled yurt of the present invention adopts a new mortise and tenon structure, which can meet the assembly requirements of adjusting the slope of the uni pole according to the climatic conditions of different seasons.

[0010] As a preferred embodiment, the end of the unni rod connected to the ceramic brain is also connected to a connecting rod, and a third connecting ear and a fourth connecting ear are provided on the ceramic brain. The third connecting ear and the fourth connecting ear are also provided with mortise holes with the same structure as the first connecting ear and the second connecting ear. The third connecting ear is fixed on the ceramic brain, and the fourth connecting ear is slidably connected to the ceramic brain along the surface of the ceramic brain so that the fourth connecting ear is close to or away from the third connecting ear.

[0011] As a preferred embodiment, a first wedge-shaped tenon is provided on the fourth connecting ear, and a first wedge-shaped groove matching the first wedge-shaped tenon is provided on the side close to the first connecting ear and the second connecting ear, and the width of the first wedge-shaped groove gradually decreases toward the side close to the third connecting ear.

[0012] As a preferred embodiment, the unini rods connected to the ceramic brain are divided into odd-numbered unini rods and even-numbered unini rods according to their positions on the circumference of the ceramic brain, and the positions of the fourth connecting ears corresponding to the odd-numbered unini rods and the even-numbered unini rods are opposite.

[0013] As a preferred embodiment, a sleeve is provided on one side of the first connecting ear and the second connecting ear close to the Hana head, and the sleeve is sleeved on the Hana head.

[0014] As a preferred embodiment, the diameters of two adjacent Hana heads gradually increase from the top ends of the two adjacent Hana heads downwards.

[0015] As a preferred embodiment, the connecting rod is detachably connected to the end of the unni rod.

[0016] As a preferred embodiment, the connecting rod is an arc-shaped rod along the circumferential direction of the Hana.

[0041] The present embodiment provides a mortise and tenon-jointed yurt, including a traditional yurt skeleton structure. The traditional yurt skeleton structure is as follows: Figure 1 As shown, Figure 2In the skeleton structure of the embodiment shown, a connecting rod 300 is provided at the end where the unni rod 100 and the hana 200 are connected. The connecting rod 300 and the unni rod 100 can be detachably connected or integrally connected. The connecting rod 300 is a horizontal rod or an arc rod along the circumference of the hana 200; Figure 4 and Figure 5 As shown, two adjacent Hana heads 201 at the top of the Hana 200 are respectively provided with two relatively arranged first connecting ears 400 and second connecting ears 500, and the first connecting ears 400 and the second connecting ears 500 are slidably matched with each Hana head 201 along the vertical direction. The specific method of sliding match can be to set through holes on the first connecting ears 400 and the second connecting ears 500, and the Hana heads 201 are inserted into the through holes to achieve up and down sliding match, or other sliding match methods in the prior art, which are not specifically limited here; in this embodiment, the first connecting ears 400, the second connecting ears 500 and the connecting rod 300 are all wooden structures; and as a preferred method, the first connecting ears 400, the second connecting ears 500 and the connecting rod 300 are all made of the same wooden material as the Unni rod 100.

[0042] In this embodiment, both ends of the connecting rod 300 are connected to the first connecting ear 400 and the second connecting ear 500 through the mortise and tenon structure designed in this embodiment; the mortise and tenon structure designed in this embodiment includes: a tenon 600 and a mortise eye 700, such as Figure 6 As shown, the tenon 600 is located at the center of the end section of the connecting rod 300, and the tenon 600 includes a cylindrical tenon 601 as a main body and a thickness gradient portion 602 located on the outer side wall of the cylindrical tenon 601; the thickness gradient portion 602 has an arc surface 6021 that smoothly transitions with the cylindrical tenon 601, and the distance between the arc surface 6021 and the center line of the cylindrical tenon 601 gradually increases from the starting point of the arc surface 6021 to the end point of the arc surface 6021. The longitudinal cross-sectional view of the tenon 600 is as shown in FIG. Figure 7 The mortise eye 700 of this embodiment is disposed on the first connecting ear 400 and the second connecting ear 500, as shown Figure 8 The mortise 700 shown has a first recessed portion 701 that cooperates with the cylindrical tenon 601, and a second recessed portion 702 that cooperates with the thickness gradient portion 602, and the arc length of the arc-shaped inner wall of the second recessed portion 702 is greater than the arc length of the arc-shaped surface 6021, and allows the thickness gradient portion 602 to slide along the second recessed portion 702 for a certain distance and then tightly cooperate with the first recessed portion 701.

[0043] In the newly designed mortise and tenon structure of this embodiment, Fig. 9As shown, the cylindrical tenon 601 of the tenon 600 can enter the first recessed portion 701, and the thickness gradient portion 602 can enter the second recessed portion 702; during assembly, the first connecting ear 400 and the second connecting ear 500 are respectively installed on the two adjacent Hana heads 201 that need to connect the Uni rod 100; the single rod in the traditional Hana 200 is generally cylindrical with a diameter of about 3cm-5cm, and the Hana head 201 connecting the first connecting ear 400 and the second connecting ear 500 is an independent section of the rod body, and the two adjacent Hana heads 201 form a V-shaped structure. Since the first connecting ear 400 and the second connecting ear 500 are in sliding cooperation with the Hana head 201 forming the V-shaped structure, the first connecting ear 400 and the second connecting ear 500 can both move up and down synchronously along the rod body of the Hana head 201. When the connecting ear 400 and the second connecting ear 500 move upward, the distance between the first connecting ear 400 and the second connecting ear 500 gradually increases. When the first connecting ear 400 and the second connecting ear 500 move downward, the distance between the first connecting ear 400 and the second connecting ear 500 gradually decreases. As a preferred method, the first connecting ear 400 and the second connecting ear 500 may not be detached after being assembled to the corresponding Hana head 201 for the first time, so as to facilitate direct assembly next time; and the specific length of the connecting rod 300 in this embodiment can be designed according to requirements, but at least the overall length of the connecting rod 300 and the tenons 600 at both ends thereof should be less than the distance between the top ends of the two adjacent Hana heads 201, so that the connecting rod 300 can be located in the V-shaped structure formed by the two adjacent Hana heads 201 after assembly.

[0044] During assembly, first build the Hana 200, connect the first connecting ear 400 and the second connecting ear 500 to the corresponding Hana head 201 respectively; then rotate the unipole 100 and the pottery brain 10. In this embodiment, the rotation connection method of the unipole 100 and the pottery brain 10 can adopt any one of the existing technologies. The purpose of rotating the unipole 100 and the pottery brain 10 in this embodiment is to facilitate the angle adjustment of the unipole 100; if the connecting rod 300 and the unipole 100 adopt a detachable connection method, the connecting rod 300 and the unipole 100 are connected as one; after the previous basic work is completed, preliminarily locate the height of the pottery brain 10, and connect the first connecting ear 400 and the second connecting ear 500 Adjust to the top of the two Hana heads 201 so that the distance between the first connecting ear 400 and the second connecting ear 500 is larger so as to facilitate placing the tenons 600 at both ends of the connecting rod 300 in the mortises 700 designed on the first connecting ear 400 and the second connecting ear 500 respectively. After the tenon 600 enters the mortise 700, by moving the first connecting ear 400 and the second connecting ear 500 downward, as the distance between the first connecting ear 400 and the second connecting ear 500 decreases, the tenon 600 completely enters the mortise 700, completing the preliminary connection between the unni rod 100 and the Hana head 201, and then adjust the height of the pottery brain 10 according to the slope requirements, so that the tenon 600 can rotate a certain range in the mortise 700, such as Fig.10 As shown, the tenon 600 and the mortise 700 can reach a tight fit state after rotation. In this embodiment, when the height of the Hana 200 is constant, the tenon 600 is rotated within the mortise 700 to achieve the adjustment of the slope of the Uni rod 100 within a certain range.

[0045] In this embodiment, a connecting rod 300 is designed at the end of the original unini rod 100, and two opposite first connecting ears 400 and second connecting ears 500 are respectively designed on two adjacent Hana heads 201 connected to the same unini rod 100, and both ends of the connecting rod 300 are connected to the first connecting ear 400 and the second connecting ear 500 by a new mortise and tenon structure. The tenon 600 in the newly designed mortise and tenon structure of this embodiment can have a certain rotational travel in the mortise eye 700, thereby satisfying the slope adjustment of the unini rod 100 within a certain range.

[0046] At the same time, this embodiment also makes full use of the V-shaped structure formed by two adjacent Hana heads 201, and connects the first connecting ear 400 and the second connecting ear 500 with the two Hana heads 201 that form the V-shaped structure. The first connecting ear 400 and the second connecting ear 500 have a certain amount of up and down sliding in the V-shaped structure to achieve adjustment of the height of the Uni rod 100 and the ground, thereby achieving slope adjustment of the Uni rod 100.

[0047] In addition, since the size and height of the internal space of the yurt need to be adjusted according to seasonal climate conditions, the traditional Hana 200 can generally be adjusted in height, so that the distance between adjacent Hana heads 201 can be changed according to the height adjustment of the Hana 200. In this embodiment, the sliding fit between the first connecting ear 400 and the second connecting ear 500 and the Hana head 201 can adapt to the position change, and at the same time, the uni rod 100 and the pottery brain 10 and the Hana head 201 are still rotationally matched, and the slope adjustment of the uni rod 100 can still be satisfied. Therefore, the above structural design of this embodiment can meet the slope adjustment of the uni rod 100 at different heights of the Hana 200, and it is very practical.

[0048] Secondly, after the two ends of the connecting rod 300 in this embodiment are bidirectionally constrained by the first connecting ear 400 and the second connecting ear 500, the stability of the overall skeleton structure can be guaranteed. In the actual construction process, the tenon 600 and the mortise 700 can be in a completely tight fit relationship after assembly, or can be in a state of active fit with a certain range of rotation. When the tenon 600 and the mortise 700 are in a tight fit state after assembly, the internal space of the overall yurt main frame is fixed and has good stability; when the tenon 600 and the mortise 700 are in a state of active fit with a certain range of rotation after assembly, more internal space can be provided in the initial assembly state. When encountering a large wind load or top load, the uni rod 100 can be rotated downward to adjust the slope to better resist the wind load and load.

[0049] When the yurt built in this embodiment needs to be dismantled, one person can hold the pottery brain 10 first, and the other person can move the first connecting ear 400 and the second connecting ear 500 upward until the pottery brain 10 is continuously raised with the upward movement of the first connecting ear 400 and the second connecting ear 500, and then rotate the unni rod 100 to make the tenon 600 and the mortise 700 rotate in the opposite direction. Fig. 9 In the illustrated state, the two can be separated, and the other end of the unni rod 100 can be removed at the same time to complete the removal of the entire skeleton to facilitate loading and transportation.

[0050] As a preferred embodiment, since when the tenon 600 and the mortise 700 are in a non-tight fit state after assembly, the connection between the unni rod 100 and the hana 200 only relies on the first connecting ear 400 and the second connecting ear 500 to constrain the connecting rod 300 from two opposite sides, in order to further improve the connection reliability between the first connecting ear 400 and the second connecting ear 500 and the connecting rod 300 and thus improve the connection reliability between the unni rod 100 and the hana 200, the tenon 600 of this embodiment also includes a conical portion 603 connected to the cylindrical tenon 601, as shown Fig.11As shown, the center line of the cone portion 603 coincides with the center line of the cylindrical tenon 601, and the diameter of the cone portion 603 gradually increases from the end away from the cylindrical tenon 601 to the end close to the cylindrical tenon 601. The mortise 700 is provided with a third recessed portion 703 corresponding to the cone portion 603. More specifically, the third recessed portion 703 is also a cone channel structure, and the size of the cone portion 603 can satisfy the requirement of smoothly passing through the first recessed portion 701 and the second recessed portion 702 to enter the third recessed portion 703. In this embodiment, when assembling the tenon 600 and the mortise 700, the cylindrical tenon 601 is still aligned with the first recessed portion 701, and the thickness gradient portion 602 is aligned with the second recessed portion 702. In the process of pushing the tenon 600 into the mortise 700, the diameter of the cone portion 603 in this embodiment gradually increases from the end away from the cylindrical tenon 601 to the end close to the cylindrical tenon 601. Therefore, as the first connecting ear 400 and the second connecting ear 500 move from top to bottom, the distance between the first connecting ear 400 and the second connecting ear 500 decreases, so the third recessed portion 703 will gradually enter a tight fit state with the cone portion 603, and then the Unni rod 100 is adjusted to make the cylindrical tenon 601 and the thickness gradient portion 602 rotate as a whole, so that the overall structure formed by the cylindrical tenon 601 and the thickness gradient portion 602 gradually tends to be tight fit with the first recessed portion 701 and the second recessed portion 702.

[0051] In this embodiment, even after the assembly is completed, the overall structure formed by the cylindrical tenon 601 and the thickness gradient portion 602 is not in a completely tight fit with the first recessed portion 701 and the second recessed portion 702, because the first connecting ear 400 and the second connecting ear 500 limit the connecting rod 300 on both sides, and at the same time, the tight fit between the conical portion 603 and the third recessed portion 703 realizes the rotation of the unipole 100 with the connecting rod 300 as the fulcrum, further improving the connection reliability between the unipole 100 and the hana 200, and achieving the purpose of not affecting the stability of the overall yurt structure on the basis of meeting the slope adjustment requirements of the unipole 100.

[0052] In this embodiment, the connection method of the unni rod 100 and the hana head 201 is also applicable to the connection of the unni rod 100 and the pottery brain 10, so as another preferred method of this embodiment, Fig.12 and Fig.14As shown, the ceramic head 10 is provided with a third connecting ear 800 and a fourth connecting ear 900. As a more preferred embodiment, the third connecting ear 800 and the fourth connecting ear 900 are arranged on the bottom surface of the ceramic head 10 to avoid that when the slope of the unini rod 100 is adjusted, the top surface of the ceramic head 10 restricts the up and down rotation of the unini rod 100 with the connection point between the unini rod 100 and the ceramic head 10 as the fulcrum. The third connecting ear 800 and the fourth connecting ear 900 are also provided with a mortise 700 with the same structure as the first connecting ear 400 and the second connecting ear 500. The third connecting ear 800 is fixed on the ceramic head 10, and the fourth connecting ear 900 is slidably connected to the ceramic head 10 to make the fourth connecting ear 900 approach or move away from the third connecting ear 800. In order to facilitate the assembly of the connecting rod 300 connected to the ceramic brain 10 in this embodiment, the third connecting ear 800 and the fourth connecting ear 900 are adaptively designed at the bottom of the ceramic brain 10, and one of them is in a sliding fit relationship with the bottom surface of the ceramic brain 10, so that the adjustment of the spacing between the third connecting ear 800 and the fourth connecting ear 900 can be achieved, and the connecting rod 300 can be clamped from both sides of the connecting rod 300 to achieve the assembly of the tenon 600 on the connecting rod 300 and the mortise 700 on the third connecting ear 800 and the fourth connecting ear 900. The specific structure of the tenon 600 and the mortise 700 in this embodiment is the same as the structure of the tenon 600 at both ends of the connecting rod 300 at the end of the uni rod 100 disclosed in the above embodiment, and the specific structure of the mortise 700 is the same as the structure of the mortise 700 on the first connecting ear 400 and the second connecting ear 500. The third connecting ear 800 and the fourth connecting ear 900 in this embodiment can be a block structure or a main structure.

[0053] As a preferred embodiment, in order to enable the fourth connecting ear 900 to be in a limited position during the movement toward the third connecting ear 800, the fourth connecting ear 900 in this embodiment is provided with a first wedge-shaped tenon 901, and the width of the first wedge-shaped tenon 901 gradually decreases from the end away from the third connecting ear 800 to the end close to the third connecting ear 800, such as Fig.14 As shown, the bottom surface near the ceramic brain 10 is provided with a first wedge-shaped groove 902 matching the first wedge-shaped tenon 901, and the width of the first wedge-shaped groove 902 gradually decreases toward the side close to the third connecting ear 800, so that when the fourth connecting ear 900 moves toward the third connecting ear 800, the first wedge-shaped tenon 901 is tightly fitted with the first wedge-shaped groove 902.

[0054] As a preferred method, Figure 3As shown, the unini rods 100 connected to the pottery brain 10 are divided into odd unini rods 101 and even unini rods 102 according to their positions on the circumference of the pottery brain 10, and the positions of the fourth connecting ears 900 corresponding to the odd unini rods 101 and the even unini rods 102 are opposite. In this embodiment, the directions in which the adjacent odd unini rods 101 and even unini rods 102 are released from the pottery brain 10 are opposite, which can avoid the possibility that the odd unini rods 101 and the even unini rods 102 are released from the pottery brain 10 at the same time after being subjected to external forces in the same direction, resulting in affecting the stability of the entire yurt main frame.

[0055] As another preferred embodiment, the first connecting ear 400 and the second connecting ear 500 are both provided with a sleeve 401 on one side close to the Hana head 201, and the sleeve 401 is sleeved on the Hana head 201. In this embodiment, the sleeve 401 that can be sleeved on the Hana head 201 is designed on the connecting ear to achieve the connection between the Hana head 201 and the first connecting ear 400, and between the Hana head 201 and the second connecting ear 500. As a more preferred manner, the diameters of two adjacent Hana heads 201 gradually increase from the top ends of the two adjacent Hana heads 201 downwards, so as the sleeve 401 continues to move downward, the fit between the Hana heads 201 and the sleeve 401 becomes tighter and tighter. As a further preferred manner, in this embodiment, after the sleeve 401 and the Hana head 201 are fully tightly fitted, the position of the bottom of the sleeve 401 is still higher than the hinge point of the two adjacent Hana heads 201, which can avoid the external force applied to the Hana head 201 by the sleeve 401 on the two adjacent Hana heads 201 being concentrated on the intersection, resulting in excessive stress at the intersection, affecting the overall stability of the Hana.

[0056] As another alternative, the first connecting ear 400 and the second connecting ear 500 of this embodiment, the side close to the Hana head 201 are all inclined surfaces inclined from top to bottom toward the center of the first connecting ear 400 and the second connecting ear 500, and a second wedge-shaped tenon is provided along the inclined surface from top to bottom, and the side of the Hana head 201 close to the first connecting ear 400 and the second connecting ear 500 is provided with a second wedge-shaped groove matching the second wedge-shaped tenon, and as a more preferred mode, the width of the second wedge-shaped groove gradually decreases from top to bottom. In this embodiment, the inclined surface design of the first connecting ear 400 and the second connecting ear 500 can match the V-shaped structure of the Hana head 201 on both sides, and the width of the second wedge-shaped groove is gradually reduced from top to bottom, which will also make the second wedge-shaped tenon move downward to the narrowed width portion, and the cooperation with the second wedge-shaped groove will change from free sliding to tight fit.

[0057] As a more preferred embodiment, the second wedge-shaped tenon is located in the middle of the inclined surface, and the second wedge-shaped groove is located in the middle of the Hana head 201, so as to achieve balanced force transmission between the Hana head 201 and the first connecting ear 400 and the second connecting ear 500, so as to facilitate the balanced transmission of the force of the unni rod 100 to the Hana 200 and evenly disperse it through the mesh structure of the Hana 200, thereby improving the ability and stability of the overall main frame of the yurt to resist external forces.

[0058] As a preferred method, in order to facilitate the replacement of the connecting rod 300, the connecting rod 300 of this embodiment is detachably connected to the end of the unni rod 100, which can be specifically adopted as follows: Fig.15 The conventional mortise and tenon structure used to connect the two rod bodies in the prior art shown or other methods used to connect the two rods can be used as long as the connection reliability of the connecting rod 300 and the unirod 100 can be met.

[0059] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
