Therefore, a feature defined as "first," "second," or "third" may explicitly or implicitly include one or more of that feature.
[0033] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.
[0034] like Figure 1-9 As shown, a first embodiment of this application provides a beam structure 100, which can be installed on a prefabricated house 200 as a roof beam. The beam structure 100 includes at least two components 1 that cooperate with each other along the longitudinal direction of the beam structure 100, namely, two first components 11 and zero or more second components 12 located between the two first components 11. Each component 1 extends longitudinally. Adjacent components 1 are connected to each other by fastening structures 2 on each component. Each first component 11 has one fastening structure 2, and each second component 12 has two oppositely arranged fastening structures 2.
[0035] Each component 1 in the beam structure 100 can be individually manufactured using a hollow blow molding process, resulting in a hollow interior and lightweight structure. Compared to injection-molded sheet structures, blow-molded beam structures exhibit higher strength and better rigidity.
[0036] like Figure 3-6 As shown, the fastening structure 2 is an irregular structure, including a recessed part 201 that is recessed into the body 1, and a protrusion 202 adjacent to the recessed part 201; wherein, the protrusion 202 of one body 1 can be inserted into the recessed part 201 of the adjacent body, so that the adjacent bodies are intersected in the transverse direction (approximately perpendicular to the longitudinal direction) to achieve preliminary fastening.
[0037] like Figure 4 and Figure 5 As shown, the groove portion 201 forms a longitudinally elongated insertion groove 203 inward; the protrusion portion 202 forms a longitudinally elongated fin 204 outward; by inserting the fin 204 of one component 1 into the insertion groove 203 of an adjacent component, further cooperation between the groove portion 201 and the protrusion portion 202 is achieved. The size of the insertion groove 203 is much smaller than that of the groove portion 201, less than 1 / 5, 1 / 10, etc. In this embodiment, "elongated" refers to the fact that the thickness of the fin 204 is much less than its length and width, for example, less than 1 / 5, 1 / 8, 1 / 10 of its length, etc., and less than 1 / 4, 1 / 5, etc. of its width.
[0038] In one embodiment, the fin 204 of one component 1 can be interference-fitted into the insertion groove 203 of an adjacent component to achieve a tight fit between the groove 201 and the protrusion 202, providing excellent support for the overall stability of the beam structure 100. In another embodiment, such as Figure 3 and Figure 5 As shown, the inner walls of the insertion groove 203 on both sides form recessed bands 205 with an arc-shaped cross-section extending longitudinally; the outer walls of the fin 204 on both sides form raised bands 206 with an arc-shaped cross-section extending longitudinally. When a fin 204 of a component 1 is inserted into the insertion groove 203 of an adjacent component, the raised bands 206 are located in the recessed bands 205, so as to achieve a tight fit and locking between the recessed portion 201 and the raised portion 202, which can provide good support for the overall stability of the beam structure 100. The raised bands 206 can be positioned approximately 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 guide it into the insertion groove 203. Since the cross-sections of the recessed band 205 and the raised band 206 are both arc-shaped, they can achieve a smooth transition on the inner wall of the insertion groove 203 and the outer wall of the fin 204, respectively; this facilitates smooth insertion during insertion and smooth removal during disassembly.
[0039] The insertion groove 203 is formed at the bottom and side of the recessed portion 201. The depth H1 of the insertion groove 203 is greater than 30% of the thickness H2 of the component at the location of the recessed portion 203, and less than 50% of the thickness H2 of the component at the location of the recessed portion 203. Figure 3 As shown, this ensures that the strength of the component 1 itself can be well maintained while ensuring the insertion depth. In particular, for hollow blow-molded beam structures, controlling this parameter can better control the stability and safety of the beam structure 100.
[0040] The recessed portion 201 has opposing first ends and second ends, and the protruding portion 202 also has opposing first ends and second ends; in order to further strengthen the fitting relationship between the parts, such as Figure 5 As shown, the groove 201 extends towards the protrusion 202 near its bottom. A recessed groove 207 is formed between the first end of the groove 201 and the first end of the protrusion 202, recessed inward towards the protrusion 202, and an extension head 208 protrudes outward towards the groove 201. The recessed groove 207 and the extension head 208 roughly form a hook-like structure. The extension head 208 of one component 1 can engage with the recessed groove 207 of an adjacent component. At this time, the second end of the groove 201 and the second end of the protrusion 202 are close together, abutting against each other, thus achieving the connection between the groove 201 and the protrusion 202. Furthermore, to facilitate engagement, the extension head 208 is provided with an inclined surface 209, opening outward. This embodiment utilizes the elastic deformation characteristics of plastic to form an interference fit in multiple directions within three-dimensional space, creating a stable locking structure; allowing adjacent components 1 to further intersect laterally, thus better achieving the fit between components 1.
[0041] like Figure 1 As shown in Figures 2, 3, and 6, the side of the beam structure 100 closest to the roof is designated as the upper part, and the side furthest from the roof is designated as the lower part. The upper surface 3 and lower surface 4 of the beam structure 100 each form an inwardly recessed support 5. The two supports 5, positioned opposite each other on the upper surface 3 and lower surface 4, can contact each other, providing internal support for the beam structure 100. The support 5 can be formed on the upper and lower surfaces of individual components 1 (e.g., the first and second components), or on the upper and lower surfaces of some components 1 (partial first component and / or partial second component).
[0042] In one embodiment, the upper surface 3 of the beam structure 100 has a longitudinally extending water passage 6. Specifically, two protruding banks 7 are formed on both sides of the upper surface of each component 1 along the longitudinal direction, and the water passage 6 is formed between the two opposing banks 7. This water passage 6 can drain rainwater collected on the roof 201 to both ends. The upper surface 3 of the beam structure 100 may also have through holes 501 to connect the water passage 6 and the hollow interior of the component 1. Figure 5As shown, when the support 5 is located at the water passage 6, a through hole 501 can be formed on the wall of the support 5 to guide at least a portion of the rainwater into the hollow component 1. This arrangement not only allows the water passage 6 to store and drain water, but also allows the support 5 and the hollow component 1 to store and drain water, increasing the drainage speed and effectively preventing excessive rainwater accumulation.
[0043] like Figure 4 As shown, the upper surface of the beam structure 100 is also provided with a positioning structure 8 and an installation structure 9 for installing the roof 201. Specifically, at least a portion of the component has a perforated positioning structure 8 on its upper surface for positioning with the roof 201, assisting in the installation of the roof. At least a portion of the component also has a protruding first mounting portion and a recessed second mounting portion on its upper surface for connecting with the roof, serving as the installation structure 9. When the recessed second mounting portion is located on the bank 7, it lowers the bank 7. At this time, it can be complementary with the installation structure of the roof 201 to seal the bank 7, making the bank 7 a whole barrier structure to prevent rainwater from overflowing from both sides.
[0044] Each first piece 11 in component 1 has a first end and a second end, wherein the first end of the first piece 11 has the fastening structure 2 described in any of the preceding embodiments, and the second end of the first piece 11 is connected to the assembly room 200. Specifically, the second end of the first piece 11 may be provided with a protruding ball head 111 and a recessed ball socket 112, which can respectively achieve an interference fit with the ball socket and ball head on the assembly room 200, thereby installing the beam structure 100 onto the assembly room 200.
[0045] Each of the second pieces 12 in the body 1 has two opposing ends, each end having a fastening structure 2 as described in any of the preceding embodiments. In one embodiment, the second piece 12 is symmetrical, and either end can engage with the first piece 11.
[0046] The beam structure 100 is configured such that, when there is no second piece 2, the fastening structures 2 of the two first pieces 11 are fastened together to form the beam structure 100. When there is one second piece 2, the second piece 2 is located between the two first pieces 11; the fastening structures 2 at both ends of the second piece 2 are fastened together with the fastening structures 2 of the two first pieces 11 respectively to form the beam structure 100. When there are multiple second pieces 2, the fastening structures 2 of the multiple second pieces 2 are fastened together, and the fastening structures 2 of the two second pieces 2 located at both ends are fastened together with the fastening structures 2 of the two first pieces 11 respectively to form the beam structure 100; wherein, each second piece 2 is located between the two first pieces 11. By selecting different numbers of second pieces 2, the beam structure 100 can be extended to accommodate different length requirements.
[0047] The second embodiment of this application provides a prefabricated house 200, which has a beam structure 100 as described in any of the preceding embodiments. Both ends of the beam structure 100 are installed on the prefabricated house 200; the roof 201 of the prefabricated house 200 is mounted on the beam structure 100.
[0048] like Figure 1 As shown (roof 201 indicated by dashed lines), the prefabricated house 200 has two adjacent rooms 202, with an M-shaped roof 201. The middle of the roof 201 is supported by a beam structure 100, which supports the roof 201 and collects rainwater from it. When expanding the prefabricated house 200 to the left or right, the beam structure 100 is used between the adjacent rooms 202, which can effectively reduce the installation difficulty of the prefabricated house 200 and meet the requirements for lightweight prefabricated houses.
[0049] Finally, it should be noted that the various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.
[0050] The above embodiments are only used to illustrate the technical solutions of this application and not to limit them; although this application has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications can still be made to the specific embodiments of this application or equivalent substitutions can be made to some technical features without departing from the spirit of the technical solutions of this application, and all such modifications should be covered within the scope of the technical solutions claimed in this application.
