Description

Technical Field

[0001] The utility model belongs to the technical field of prefabricated cabins, and in particular relates to a truss for a prefabricated cabin and a prefabricated cabin. Background Art

[0002] At present, there are various ways to segment prefabricated cabin-type substations, and the span of cabin segments varies. When the span is large, the bending strength of the cabin segmented beams is insufficient, which limits the segmentation of the cabin. To solve this problem, two methods are often used, namely, adding support under the spliced ​​beams or strengthening the spliced ​​beam structure. Figure 6 As shown, in method 1, the support columns and support walls are welded and fixed under the spliced ​​beams. The positions of the support walls and support columns occupy the space inside the cabin, affecting the placement of the electrical equipment inside the prefabricated cabin, and the support columns or support walls cannot be removed later, affecting the appearance; Figure 7 As shown, the second method is to process the spliced ​​beams into a truss welded with profiles. The structure is surrounded by rectangular tubes to form a rectangle, and vertical rectangular tubes and oblique rectangular tubes are welded alternately inside the rectangle. The processing process of this structure is difficult, and the cutting of the profiles requires corner cutting. During welding, the space at the overlap position of some profiles is too small to be welded. The overall material is heavy, and the material cost and labor cost are high.

[0003] Therefore, it is a technical problem to be solved urgently to develop a truss for prefabricated cabins and a prefabricated cabin that can have high structural strength under the conditions of light overall truss weight, low material cost, and low processing difficulty, and can also ensure sufficient bending strength when the span of the cabin section is large without the need for additional support.

In order to simplify the disclosure of the present invention, the components and settings of specific examples are described below. Of course, they are only examples, and the purpose is not to limit the present invention. In addition, the present invention may repeat reference numbers and / or reference letters in different examples, and such repetition is for the purpose of simplification and clarity, and does not itself indicate the relationship between the various embodiments and / or settings discussed.

[0048] In some embodiments of the present application, a prefabricated cabin is provided, which is formed by splicing a plurality of prefabricated cabin boxes 100.

[0049] Due to the different lengths of the prefabricated cabin boxes, such as Figures 1 to 5 As shown, for a prefabricated cabin box 100 with a longer length, a prefabricated cabin truss 200 with higher bending strength is required. The prefabricated cabin truss 200 is connected to the prefabricated cabin box 100 to ensure the structural strength of the prefabricated cabin box 100. In the case of no need to set a vertical support column under the prefabricated cabin truss 200, the bending strength of the prefabricated cabin box 100 can still be ensured.

[0050] Specifically, the prefabricated cabin box body 100 includes two prefabricated cabin trusses 200 , and the two prefabricated cabin trusses 200 are respectively arranged on both sides of the prefabricated cabin box body 100 .

[0051] In some embodiments of the present application, Figure 1 , Figure 3 As shown, the truss for the prefabricated cabin includes an upper support portion 300, a lower support portion 400, a vertical support portion 500, a corrugated connection portion 600 and a splicing connection portion.

[0052] The upper support portion 300 extends in a horizontal direction.

[0053] The lower support portion 400 is extended and disposed below the upper support portion 300 along the extension direction of the upper support portion 300 .

[0054] Specifically, the upper support portion 300 and the lower support portion 400 are arranged in parallel.

[0055] A plurality of vertical support parts 500 are connected between the upper support part 300 and the lower support part 400. The plurality of vertical support parts 500 are disposed between the upper support part 300 and the lower support part 400 at intervals.

[0056] A corrugated connection portion 600 is further extended to a region formed between the upper support portion 300 and the lower support portion 400 .

[0057] like Figure 2 , Figure 4As shown, the corrugated connection portion 600 is connected between two adjacent vertical support portions 500 .

[0058] Since the plurality of corrugated connection parts 600 extend in the direction of the upper support part 300 and the lower support part 400, the overall length of the plurality of corrugated connection parts 600 is relatively long, which plays a key role in the bending strength of the prefabricated cabin truss 200. The corrugated connection parts 600 can adopt corrugated connection plates.

[0059] In order to ensure sufficient bending strength, the distance between adjacent wave crests of the corrugated connecting portion 600 is not greater than 300 mm.

[0060] The height of the crest is 30 mm to 40 mm.

[0061] The height of the trough is 30 mm to 40 mm.

[0062] In order to reduce the overall weight of the prefabricated cabin truss 200 , the thickness of the corrugated connection part 600 is limited to 0.8 mm to 1.5 mm.

[0063] In some embodiments of the present application, the upper support portion 300 may adopt a square tube structure.

[0064] The lower support portion 400 may also adopt a square tube structure.

[0065] The vertical support portion 500 may also adopt a square tube structure.

[0066] In order to facilitate the connection between two adjacent prefabricated cabin boxes 100 , a splicing connection portion is provided on the upper support portion 300 or the lower support portion 400 .

[0067] In some embodiments of the present application, there are multiple splicing connection parts, and the multiple splicing connection parts are arranged at intervals on the upper support part 300, or on the lower support part 400.

[0068] Specifically, the splicing connection portion is a third reserved connection hole 710 that passes through the upper support portion 300 or the lower support portion 400 .

[0069] In this embodiment, the third reserved connection hole 710 is opened on the upper support portion 300 .

[0070] Specifically, the third reserved connection hole 710 is arranged to penetrate the upper support portion 300 along the horizontal direction.

[0071] The fastener passes through the third reserved connection hole 710 to achieve the connection between two adjacent prefabricated cabin boxes 100.

[0072] In order to facilitate the wiring between two adjacent prefabricated cabin boxes 100, a wiring passage 800 is formed on the prefabricated cabin truss.

[0073] In some embodiments of the present application, since the combined force and torque at the end of the prefabricated cabin truss 200 are relatively small, the wiring passage 800 is formed between the end of the upper support portion 300 and the end of the lower support portion 400 .

[0074] In order to ensure the structural strength of the wiring passage 800 , vertical support portions 500 are provided on both sides of the wiring passage 800 .

[0075] That is, no corrugated connection portion 600 is provided between two adjacent vertical support portions 500 at the end, and the space formed thereby is the wiring passage 800 .

[0076] In some embodiments of the present application, Figure 5 As shown, in the prefabricated cabin body 100 , two prefabricated cabin trusses 200 are arranged oppositely on both sides of the prefabricated cabin body 100 .

[0077] A plurality of detachable center beams 910 are connected between the two prefabricated cabin trusses 200 .

[0078] In order to realize the quick connection between the detachable middle support beam 910 and the prefabricated cabin truss 200, a plurality of first reserved connection holes 310 are opened on one side of the upper support part 300. The fasteners pass through the first reserved connection holes 310 to realize the connection between the upper support part 300 and the detachable middle support beam 910, thereby realizing the convenient and detachable connection between the prefabricated cabin truss 200 and the detachable middle support beam 910.

[0079] During transportation, the prefabricated cabin box 100 will be subjected to forces such as bumps and collisions. In order to reduce the deformation of the prefabricated cabin box 100, a number of inclined detachable diagonal braces 920 are temporarily connected between the upper and lower ends of the prefabricated cabin box 100. At this time, the upper ends of the detachable diagonal braces 920 are detachably connected to the prefabricated cabin truss 200.

[0080] In some embodiments of the present application, a plurality of second reserved connection holes 410 are provided on the lower surface of the lower support portion 400. The fasteners pass through the second reserved connection holes 410 and are connected to the detachable diagonal brace 920, thereby achieving a detachable connection between the detachable diagonal brace 920 and the lower support portion 400.

[0081] In some embodiments of the present application, due to the different lengths of the prefabricated cabin box 100 and the length of the prefabricated cabin box 100 is a standard value, they are all arranged in series. In order to improve the versatility of the prefabricated cabin trusses 200 and realize the pre-production of the prefabricated cabin trusses 200, multiple prefabricated cabin trusses 200 are designed to be equal in length according to the series length of the prefabricated cabin box 100.

[0082] According to the length of the prefabricated cabin box body 100, a prefabricated cabin truss 200 of equal length is directly selected.

[0083] At the same time, the prefabricated cabin truss 200 can be designed in a standardized and modular manner.

[0084] In the description of the above embodiments, specific features, structures, materials or characteristics may be combined in a suitable manner in any one or more embodiments or examples.

[0085] The above is only a specific implementation method of the utility model, but the protection scope of the utility model is not limited to this. Any changes or substitutions that can be easily thought of by any technician familiar with the technical field within the technical scope disclosed by the utility model should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
