Description

Technical Field

[0001] This utility model relates to a prefabricated structure, particularly a T-shaped prefabricated module, a transport body, and a bridge. Background Technology

[0002] Modular structures, due to their high efficiency and flexibility, have been widely used in industrial and infrastructure construction, such as buildings and bridges. However, most existing modular structures cannot be folded, and their design makes them unsuitable for transport in container form.

[0003] There are also existing structures that use T-shaped prefabricated modules for assembly, which usually include two panels and a longitudinal beam located between the two. The two panels are respectively connected to the upper two sides of the longitudinal beam by hinges to facilitate folding and unfolding. However, this structure has the following defects: (1) When the panel is hinged to the longitudinal beam, the bending moment cannot be effectively transmitted at the hinge node, and the panel and the longitudinal beam are difficult to cooperate in bearing the force, resulting in a reduction in the overall stiffness of the structure; (2) There will be a large gap at the hinge of the panel and the longitudinal beam, resulting in poor sealing and poor waterproof and dustproof effect. Utility Model Content

[0004] The purpose of this utility model is to overcome the above-mentioned shortcomings of the prior art and provide a T-shaped prefabricated module, a transport body, and a bridge with good rigidity, good sealing performance, and high transportation efficiency.

[0005] The technical solution of this utility model is: One type of T-shaped prefabricated module of this utility model includes a first plate, a second plate, and a longitudinal beam disposed between the two; the first plate is fixedly connected to the longitudinal beam, and the second plate is hinged to the longitudinal beam; and when the second plate is flipped to a position perpendicular to the longitudinal beam, the second plate is detachably and fixedly connected to the longitudinal beam by a first locking member.

[0006] Furthermore, when the second plate is flipped to a position perpendicular to the longitudinal beam, the second plate is detachably and fixedly connected to the first plate by the second locking member.

[0007] Furthermore, the top surface of the longitudinal beam is provided with a connecting plate, which extends toward the second plate to form an extension; the extension is provided with a plurality of first connecting holes spaced apart along the length of the longitudinal beam; the second plate is provided with corresponding second connecting holes that match the first connecting holes; the longitudinal beam is fixedly connected to the second plate by the first locking member passing through the first connecting holes and the second connecting holes.

[0008] Furthermore, both the first and second locking components are bolt sets; the second plate is connected to a threaded sleeve at the second connecting hole, and the longitudinal beam is threadedly connected to the threaded sleeve of the second plate by the bolts of the bolt set passing through the corresponding first and second connecting holes.

[0009] Furthermore, the second plate is connected to the longitudinal beam via a hinge group; the hinge group consists of multiple hinges, which are arranged intermittently and / or continuously along the hinge axis between the second plate and the longitudinal beam.

[0010] Furthermore, the hinge includes a first bushing, a second bushing, and a pin; the first bushing extends along one side of the upper part of the longitudinal beam, and at least one second bushing is arranged on the second plate corresponding to the hinge point with the longitudinal beam; the second bushing is connected to the first bushing, and the pin passes through the shaft hole of the first bushing and the second bushing to achieve hinge connection, and the end of the pin is provided with a limiting structure to prevent it from falling out.

[0011] Furthermore, the first plate, the second plate, and the longitudinal beam are all core plate structures with a sandwich layer; the first plate is welded to the longitudinal beam; the second plate can rotate around the hinge point between a first position and a second position; when in the first position, the second plate is parallel to the longitudinal beam; when in the second position, the second plate is perpendicular to the longitudinal beam.

[0012] One type of transport body according to this utility model is characterized by including the aforementioned T-shaped prefabricated modules; the number of T-shaped prefabricated modules is two sets; during transportation, the two sets of T-shaped prefabricated modules are combined to form a box structure; the first plate of one T-shaped prefabricated module serves as one side wall of the box, and the second plate is turned down 90° to a position parallel to the longitudinal beam to form a double-layer structure, serving as the top plate of the box; the first plate of the other T-shaped prefabricated module serves as the other side wall of the box, and the second plate is turned down 90° to a position parallel to the longitudinal beam to form a double-layer structure, serving as the bottom plate of the box; thereby forming a transport body that conforms to the dimensions of a container.

[0013] One type of bridge according to this utility model has a superstructure composed of multiple T-shaped prefabricated modules as described above.

[0014] Furthermore, connecting rod groups are provided between the longitudinal beams of adjacent T-shaped prefabricated modules, and strut groups are provided between the longitudinal beams of the T-shaped prefabricated modules located at the edge of the bridge and the outermost slab.

[0015] The beneficial effects of this utility model are: (1) By adding a first locking member to the connection between the second plate and the longitudinal beam, the T-shaped prefabricated module can meet the rigid force and greatly improve the connection strength. On the other hand, compared with only setting the hinge group, the connection through the first locking member can ensure that the second plate can be flipped up to be perpendicular to the longitudinal beam and achieve seamless docking. (2) By folding and assembling two sets of T-shaped prefabricated modules to form a transport body that conforms to the size of a container, it is equivalent to the transport body itself forming a container structure, thus eliminating the need for additional containers, greatly reducing transportation costs. Moreover, each set of T-shaped prefabricated modules only needs to be folded on one side, not both sides, which greatly simplifies the connection structure and makes operation easier. (3) By setting up a linkage group, the connection strength between adjacent T-shaped prefabricated modules can be improved, and the materials used can be reduced, the cost reduced, and the weight reduced; (4) By splicing together several standardized T-shaped prefabricated modules to form the main structure of the bridge superstructure, the transportation efficiency and assembly speed can be greatly improved, and the maintenance and dismantling of the bridge can be more flexible, reducing the difficulty of traditional bridge demolition and lowering the later maintenance cost.

Detailed Implementation

[0018] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0019] Example 1

[0020] like Figures 1-3As shown: A T-shaped prefabricated module includes a first plate 1, a second plate 2, and a longitudinal beam 3 located between the two, which are connected to form a T-shaped cross-section structure. The first plate 1 and the second plate 2 are spliced ​​together along the length direction. The first plate 1 is fixedly connected to the longitudinal beam 3, and the second plate 2 is hinged to the longitudinal beam 3. When the second plate 2 is flipped to a position perpendicular to the longitudinal beam 3, the second plate 2 is detachably and fixedly connected to the longitudinal beam 3 by a first locking member 4.

[0021] Specifically, the first plate 1, the second plate 2, and the longitudinal beam 3 are preferably core plates 5, which are preferably made of steel, such as stainless steel or carbon steel. The core plate includes an upper panel 51, a lower panel 52, a sandwich layer 53 disposed between the two, and a frame 54 disposed around the sandwich layer. The sandwich layer 53 can be a hollow tube array, a honeycomb layer, or a corrugated layer, etc. In this embodiment, the sandwich layer 53 is preferably a hollow tube array.

[0022] In this embodiment, the first plate 1 is welded and fixed to the longitudinal beam 2. For example, the top surface of the core plate frame 54 of the longitudinal beam is welded to the lower part of the core plate frame of the first plate 1, and the upper part of the outer side surface of the core plate frame of the longitudinal beam 3 is welded to the bottom surface of the first plate 1.

[0023] In this embodiment, the second plate 2 is hinged to the longitudinal beam 3 and can be rotated within a 90° range around the hinge point. The hinge point is positioned such that the second plate 2 can rotate between a first position and a second position around the hinge point; when in the first position, the second plate 2 is parallel to and in contact with the longitudinal beam 3; when in the second position, the second plate 2 is perpendicular to the longitudinal beam 3 and can be locked to the longitudinal beam 3 by the first locking member 4, and also locked to the first plate 1 by the second locking member 6. By rotating the second plate 2 to the first position, the entire T-shaped prefabricated module can be folded, and it can be combined with other T-shaped prefabricated modules to form a box structure, meeting container transportation standards; by rotating the second plate 2 to the second position, the original T-shaped structure can be restored, facilitating assembly with other T-shaped prefabricated modules to form building structures such as bridges and factories.

[0024] In this embodiment, the top surface of the longitudinal beam 3 is provided with a connecting plate 31, which extends toward the second plate 2 to form an extension 311. The extension 311 has a plurality of first connecting holes spaced apart along the length of the longitudinal beam. The second plate 2 has corresponding second connecting holes that match the first connecting holes. A threaded sleeve 21 is welded to the second plate 2 at the second connecting hole. The longitudinal beam 3 is threadedly connected to the second plate 2 by a first locking member 4 passing through the first connecting hole, the second connecting hole, and the threaded sleeve 21, thereby fixing the longitudinal beam 3 to the second plate 2. Preferably, the first locking member 4 is a bolt group. A threaded sleeve 21 is welded to the inner surface of the lower panel 52 of the core plate of the second plate 2 at a position corresponding to each second connecting hole. Each bolt of the bolt group passes through the corresponding first connecting hole, the second connecting hole, and the threaded sleeve 21 of the second plate 2 for threaded connection.

[0025] It is understood that the connecting plate 31 can be directly connected to the outer surface of the frame of the longitudinal beam core plate, or it can be directly formed from the frame of the core plate, that is, the outer surface of the frame extends outward to form the extension portion 311. In this embodiment, the connecting plate 31 is preferably formed directly from the frame 54 of the core plate.

[0026] like Figure 4 As shown: In this embodiment, the second plate 2 and the longitudinal beam 3 are connected by a hinge group; the hinge group consists of multiple sets of hinges 7, which are arranged at intervals along the hinge axis of the second plate 2 and the longitudinal beam 3. Each set of hinges 7 includes a first bushing 71, a second bushing 72, and a pin 73; the first bushing 71 extends along one side of the upper part of the longitudinal beam 3 through a hinge plate 75, specifically extending along the outside of the extension 311 of the connecting plate; the bottom surface of the second plate 2 is welded with two spaced second bushings 72 at the hinge point with the longitudinal beam 3, and the first bushing 71 can extend to the space between the two second bushings 72 to mate with them, and a plastic gasket 74 is provided between adjacent bushings; wherein the first bushing 71 is a long bushing, and the two second bushings 72 are short bushings; after mating, the pin 73 passes through the short bushing, the plastic gasket, the long bushing, the plastic gasket, and another short bushing in sequence to achieve hinge, and the end of the pin 73 is provided with a limiting structure to prevent it from falling out.

[0027] In this embodiment, the side where the first plate 1 and the second plate 2 are connected is provided with an upwardly extending connecting portion 55. Multiple threaded holes are spaced apart along the length direction on the connecting portion 55. The second locking member 6 is a bolt group, through which the first plate 1 and the second plate 2 are connected and fixed. The connecting portion 55 can be formed by extending an extension plate upward from the side frame 54 of the core plate, or by bending a bent plate upward along the length direction from the side of the top panel of the core plate.

[0028] In this embodiment, the longitudinal beam 3 is provided with a longitudinal beam end flange 32 on the end face where it connects with the longitudinal beams of other T-shaped prefabricated modules. The longitudinal beam end flange 32 is welded to the end face of the longitudinal beam 3 and extends out on both sides and the bottom. The extended parts are provided with connection holes to facilitate the connection between adjacent longitudinal beams 3. Similarly, the first plate 1 and the second plate 2 are also provided with flange plates 11 on the end face and side face where they connect with other T-shaped prefabricated modules.

[0029] In this embodiment, the entire T-shaped prefabricated module is prefabricated in the factory. Once transported to the site, it can be connected and assembled with other T-shaped prefabricated modules or other components. The structure is simple and greatly improves assembly efficiency.

[0030] In summary, this embodiment adds bolt connections to the hinged connection between the second plate and the longitudinal beam. On the one hand, this enables the T-shaped prefabricated module to meet the rigidity requirements and greatly improves the connection strength. On the other hand, compared with only setting the hinge group, the bolt connection can ensure seamless docking when the second plate is flipped up to be perpendicular to the longitudinal beam.

[0031] Example 2

[0032] This embodiment is based on Comparative Document 1, which sets up two sets of T-shaped prefabricated modules to form a box structure, creating the main transport body 8, as detailed below. Figure 5 As shown.

[0033] During transportation, the first plate 1 of one T-shaped prefabricated module serves as one side wall of the container, and the second plate 2 of the same module is folded down 90° to a position parallel to the longitudinal beam 3 (i.e., at the first position), so that the longitudinal beam 3 and the second plate 2 are stacked to form a double-layer structure, which serves as the top plate of the container; the first plate of the other T-shaped prefabricated module serves as the other side wall of the container, and the second plate of the same module is folded down 90° to a position parallel to the longitudinal beam to form a double-layer structure, which serves as the bottom plate of the container. Then, corner fittings are installed at the upper and lower four corners of the main body of the transport, thereby forming a transport body 8 that conforms to the dimensions of a container.

[0034] During on-site construction, the two sets of T-shaped prefabricated modules transported to the site are disassembled, and the second plate 2 is flipped upward to a position perpendicular to the longitudinal beam 3 (i.e., at the second position). Then, it is locked to the longitudinal beam 3 by the first locking member 4 (i.e., bolt group) and locked to the first plate 1 by the second locking member 6 (i.e. bolt group), thereby restoring the original T-shaped prefabricated module structure.

[0035] This embodiment assembles two sets of T-shaped prefabricated modules into a transport body that conforms to the dimensions of a shipping container. This is equivalent to the transport body itself forming a container structure, thus eliminating the need for additional containers and greatly reducing transportation costs. Furthermore, each set of T-shaped prefabricated modules only needs to be folded on one side, not both sides, which greatly simplifies the connection structure and makes operation easier. Moreover, assembling two sets of large T-shaped prefabricated modules greatly improves transportation efficiency, and the folding and unfolding operations are convenient, saving time and effort.

[0036] Example 3

[0037] like Figure 6 As shown: A bridge, the superstructure 9 of which is composed of multiple T-shaped prefabricated modules as described in Example 1.

[0038] The sides and ends of the first plate 1 and the second plate 2 of each T-shaped prefabricated module are spliced ​​together by each flange plate 11. The longitudinal beams 3 of each T-shaped prefabricated module are connected by longitudinal beam end flanges 32. After splicing, the upper main structure 9 of the bridge is formed, and the first plate 1 and the second plate 2 form the road slab of the bridge.

[0039] In this embodiment, a linkage group is provided between the longitudinal beams of adjacent T-shaped prefabricated modules. That is, several linkages 91 are provided between the longitudinal beams of each adjacent T-shaped prefabricated module. The linkages 91 are connected to the lower middle or lower part of the adjacent longitudinal beam 3, and the linkages 91 are arranged at intervals along the length of the longitudinal beam 3. By setting the linkage group, the connection strength between adjacent T-shaped prefabricated modules can be improved, while reducing material usage, lowering costs, and reducing weight.

[0040] In addition, a strut group, consisting of multiple struts 92, is provided between the longitudinal beam 3 of the T-shaped prefabricated module located at the edge of the bridge and the outer slab to improve the support strength.

[0041] This embodiment uses several standardized T-shaped prefabricated modules to form the main superstructure of the bridge, which can greatly improve transportation efficiency and assembly speed, and make the bridge maintenance and dismantling more flexible, reducing the difficulties of traditional bridge demolition and lowering the later maintenance costs.

[0042] Furthermore, the term "connection" should be interpreted broadly, for example, it can include fixed connections, detachable connections, or integral connections; it can include direct connections or indirect connections through an intermediate medium, and it can also include 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.

[0043] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature.
