DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments of the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0032] The terms "first", "second", and "third" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the technical features indicated. Thus, a feature defined as "first", "second", and "third" may explicitly or implicitly include one or more of the features.

[0033] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0034] like Figure 1-9 As shown, the first embodiment of the present application provides a beam structure 100, which can be installed on an assembled house 200 and serve as the beam of the assembled house 200. The beam structure 100 includes at least two parts 1 that cooperate with each other along the longitudinal direction of the beam structure 100, that is, it includes two first parts 11, and zero, one or more second parts 12 located between the two first parts 11. Each part 1 is formed by extending along the longitudinal direction. Two adjacent parts 1 are connected to each other by the buckling structures 2 on each part. Each first part 11 has a buckling structure 2, and each second part 12 has two buckling structures 2 arranged opposite to each other.

[0035] Each body 1 in the beam structure 100 can be made by hollow blow molding, and the interior is hollow and the structure is light. Compared with the sheet structure formed by injection molding, the beam structure formed by blow molding has higher strength and better intensity.

[0036] like Figure 3-6 As shown, the snap-fit ​​structure 2 is a special-shaped structure, including a groove portion 201 recessed into the body 1, and a protrusion 202 adjacent to the groove portion 201; wherein the protrusion 202 of one body 1 can be inserted into the groove portion 201 of an adjacent body, so that the adjacent bodies are staggered with each other in the horizontal direction (roughly perpendicular to the longitudinal direction) to achieve preliminary snap-fit.

[0037] like Figure 4 and Figure 5 As shown, the groove portion 201 forms a longitudinally long and narrow insertion groove 203 inwardly; the protrusion 202 forms a longitudinally long and narrow fin 204 outwardly; the fin 204 of one body 1 is inserted into the insertion groove 203 of the adjacent body to achieve further matching between the groove portion 201 and the protrusion 202. The size of the insertion groove 203 is much smaller than the groove portion 201, less than 1 / 5, 1 / 10, etc. The narrow and long in this embodiment means that the thickness of the fin 204 is much lower than its length and width, for example, less than 1 / 5, 1 / 8, 1 / 10, etc. of the length, and less than 1 / 4, 1 / 5, etc. of the width.

[0038] In one embodiment, the fin 204 of one body 1 can be inserted into the insertion groove 203 of the adjacent body with interference fit, so as to achieve a tight fit between the groove portion 201 and the protrusion portion 202, which can provide good support for the overall stability of the beam structure 100. Figure 3 and Figure 5 As shown, the inner walls on both sides of the insertion groove 203 respectively form a concave concave belt 205 with an arc-shaped cross section extending in the longitudinal direction; the outer walls on both sides of the fin 204 respectively form a convex convex belt 206 with an arc-shaped cross section extending in the longitudinal direction; the fin 204 of one body 1 is inserted into the insertion groove 203 of the adjacent body, so that the convex belt 206 is located in the concave belt 205, so as to achieve a tight fit and locking engagement between the groove part 201 and the convex part 202, which can provide good support for the overall stability of the beam structure 100. Among them, the convex belt 206 can be arranged roughly close to the middle of the outer wall of the fin 204 and away from its edge, so that the edge of the fin 204 can play a role in guiding the fin 204 into the insertion groove 203. Since the cross-sections of the recessed band 205 and the raised band 206 are both arc-shaped, a smooth transition can be achieved between the inner wall of the insertion slot 203 and the outer wall of the fin 204 respectively; it is convenient for transitional insertion during insertion and transitional removal during removal.

[0039] The insertion groove 203 is formed at the bottom and side of the groove portion 201, and the depth H1 of the insertion groove 203 is greater than 30% of the thickness H2 of the body where the groove portion 203 is located, and less than 50% of the thickness H2 of the body where the groove portion 203 is located. Figure 3 As shown, while ensuring the insertion depth, the strength of the body 1 itself can be well maintained, especially for the hollow blow-molded beam structure. Controlling this parameter can better control the stability and safety of the beam structure 100.

[0040] The groove portion 201 has a first end and a second end opposite to each other, and the protrusion portion 202 also has a first end and a second end opposite to each other; in order to further strengthen the matching relationship between the components, as shown in FIG. Figure 5 As shown, the groove portion 201 extends toward the protrusion 202 near the bottom, and a recessed groove 207 recessed toward the protrusion 202 is formed between the first end of the groove portion 201 and the first end of the protrusion 202, and an extension head 208 protruding toward the groove portion 201 from the outside, and the recessed groove 207 and the extension head 208 roughly form a hook-shaped structure; wherein, the extension head 208 of one body 1 can be inserted into the recessed groove 207 of the adjacent body, at this time, the second end of the groove portion 201 and the second end of the protrusion 202 are close together and mutually abut against each other, so as to realize the hooking of the groove portion 201 and the protrusion 202. In addition, in order to facilitate mutual insertion, the extension head 208 is provided with an inclined surface 209, which is open outward. This embodiment can use the characteristics of plastic elastic deformation to form interference fit in multiple directions in three-dimensional space, forming a stable locking structure; so that the adjacent bodies 1 are further interlaced in the horizontal direction, so as to better realize the fit between the bodies 1.

[0041] like Figure 1 , 2, 3 and 6, the side of the beam structure 100 close to the roof is the upper side, and the side away from the roof is the lower side. The upper surface 3 and the lower surface 4 of the beam structure 100 respectively form inwardly concave support bodies 5; the two support bodies 5 arranged opposite to each other on the upper surface 3 and the lower surface 4 can contact each other to provide internal support for the beam structure 100. The support body 5 can be formed on the upper surface and the lower surface of each body 1 (for example, the first body and the second body), and can also be formed on the upper surface and the lower surface of a part of the body 1 (part of the first body and / or part of the second body).

[0042] In one embodiment, the upper surface 3 of the beam structure 100 is formed with a water channel 6 extending in the longitudinal direction. Specifically, two sides of the upper surface of each body 1 are respectively formed with two raised banks 7 in the longitudinal direction, and the water channel 6 is formed between the two opposite banks 7. The water channel 6 can drain the rainwater collected on the roof 201 to both ends. The upper surface 3 of the beam structure 100 can also be provided with a through hole 501 to connect the water channel 6 and the hollow interior of the body 1. Figure 5As shown, when the support body 5 is located at the water passage 6, a through hole 501 can be opened on the wall of the support body 5 to guide at least a portion of the rainwater into the hollow body 1. This arrangement not only allows the water passage 6 to store and drain water, but also the support body 5 and the hollow body 1 can store and drain water, which increases the speed of drainage and effectively prevents excessive accumulation of rainwater.

[0043] like Figure 4 As shown, the upper surface of the beam structure 100 is also provided with a positioning structure 8 and a mounting structure 9 for mounting the roof 201. Specifically, the upper surface of at least a part of the body has a positioning structure 8 with holes, which is used for positioning with the roof 201 and assisting the installation of the roof. The upper surface of at least a part of the body also has a raised first mounting portion and a recessed second mounting portion, which are used to connect with the roof as the mounting structure 9. When the recessed second mounting portion is located on the bank 7, it lowers the bank 7. At this time, the bank 7 can be sealed by complementing with the mounting structure of the roof 201, so that the bank 7 becomes an integral blocking structure to prevent rainwater from overflowing from both sides.

[0044] Each first piece 11 in the body 1 has a first end and a second end opposite to each other, wherein the first end of the first piece 11 has the buckling structure 2 described in any of the above embodiments, and the second end of the first piece 11 is connected to the assembled house 200. Specifically, the second end of the first piece 11 can be provided with a protruding ball head 111 and a recessed ball socket 112, respectively, which can respectively achieve interference fit with the ball socket and the ball head on the assembled house 200, so that the beam structure 100 is installed on the assembled house 200.

[0045] Each second piece 12 in the body 1 has two opposite ends, wherein each end has the buckling structure 2 described in any of the above embodiments. In one embodiment, the second piece 12 is a symmetrical body, and either end can be matched with the first piece 11.

[0046] The beam structure 100 is configured as follows: when there is no second member 2, the buckling structures 2 of the two first members 11 buckle with each other to form the beam structure 100. When there is one second member 2, the second member 2 is located between the two first members 11; the buckling structures 2 at both ends of the second member 2 buckle with the buckling structures 2 of the two first members 11 to form the beam structure 100. When there are multiple second members 2, the buckling structures 2 of the multiple second members 2 buckle with each other, and the buckling structures 2 of the two second members 2 located at both ends buckle with the buckling structures 2 of the two first members 11 to form the beam structure 100; wherein the second member 2 is located between the two first members 11. By selecting different numbers of second members 2, the beam structure 100 can be extended to meet the requirements of different lengths.

[0047] The second embodiment of the present application provides an assembled house 200, which has the beam structure 100 described in any of the above embodiments. Both ends of the beam structure 100 are installed on the assembled house 200; and the roof 201 of the assembled house 200 is mounted on the beam structure 100.

[0048] like Figure 1 As shown (the roof 201 is indicated by a dotted line), the assembled house 200 has two adjacent rooms 202, and the roof 201 thereon is M-shaped; the middle part of the roof 201 is mounted on the beam structure 100, so as to support the roof 201 and collect rainwater from the roof 201. When the assembled house 200 is expanded left and right, the beam structure 100 is used between the adjacent rooms 202, which can well reduce the installation difficulty of the assembled house 200 and meet the requirements for lightweight assembled houses.

[0049] Finally, it should be noted that: the various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.

[0050] The above implementation modes are only used to illustrate the technical solution of the present application rather than to limit it. Although the present application has been described in detail with reference to the preferred implementation modes, ordinary technicians in the relevant field should understand that the specific implementation modes of the present application can still be modified or some technical features can be replaced by equivalents without departing from the spirit of the technical solution of the present application, which should be included in the scope of the technical solution requested for protection in the present application.
