Description

Technical Field

[0001] This application belongs to the field of corridor structure technology, specifically relating to a temporary enclosed truss corridor structure. Background Technology

[0002] A truss corridor is a long, narrow passageway that uses a truss structure as its main support. It is typically used to span buildings with large spans or to house equipment located between two buildings.

[0003] Based on user requirements, some truss corridors need to be fitted with cover plates on the outside to enhance internal airtightness and prevent external dust and impurities from entering. In existing technology, the cover plates are installed sequentially along the length of the truss corridor using a bolt and nut structure, and four cover plates need to be installed at each point in the truss corridor to ensure that the top, bottom, and sides of the truss corridor are all covered.

[0004] The inventors discovered that existing enclosed truss corridor structures require a long time to install the cover plates during installation, and a long time to remove the cover plates when they are no longer needed, which cannot meet users' needs for temporary closure of truss corridors. Utility Model Content

[0005] This application provides a temporary enclosed truss corridor structure, which aims to use detachable components to enclose the truss corridor, so as to facilitate disassembly and installation, thereby improving the efficiency of truss corridor structure installation and adjustment.

[0006] To achieve the above objectives, the technical solution adopted in this application is as follows:

[0007] A temporary enclosed truss corridor structure is provided, comprising multiple sets of prefabricated components arranged along a predetermined direction between two buildings. Each set of prefabricated components has a docking frame coaxially disposed at both ends. The prefabricated components at the ends are connected to the buildings through the docking frames, and adjacent sets of prefabricated components are connected through two docking frames. Each set of prefabricated components further includes:

[0008] Multiple enclosed strips are set between the corresponding two docking frames and are spaced apart along the circumference of the assembled body;

[0009] Each of the closed strips is connected to two docking frames at both ends. Two adjacent closed strips along the circumference of the assembly body are connected by a separable connection structure to form a cylindrical structure that closes the outer circumference of the assembly body.

[0010] In one possible implementation, the separable connection structure includes:

[0011] The Velcro hook face is provided on the side of one of the said closure strips; and

[0012] The hook and loop face is located on the side of another closed band and is used to engage with the hook and loop face to connect the sides of the two closed bands.

[0013] In one possible implementation, the thickness of the closed strip alternately increases and decreases along its length to form a plurality of alternating thick and thin portions;

[0014] Both the hook and loop face of the hook and loop face are located on the thick part.

[0015] In one possible implementation, the side of the closure strip has an outwardly curved bend, and two adjacent closure strips along the circumference of the assembly are connected by the two bends.

[0016] Both the hook and loop face of the hook and loop face are located on the inner side of the bent portion.

[0017] In one possible implementation, the docking frame has a reserved hole that extends through the axial direction of the assembled body;

[0018] A positioning screw is provided between two adjacent assembly parts; the positioning screw is adapted to be inserted into two pre-reserved holes that are interconnected, and its two ends extend to both sides of the two mating frames respectively;

[0019] Both ends of the positioning screw are threaded with locking nuts; each locking nut is used to engage with the outer surface of the docking frame on the same side to connect the two docking frames and restrict the relative movement of the two docking frames.

[0020] In one possible implementation, the inner side of the docking frame has four inner pillars; the four inner pillars are respectively connected to the four corners of the docking frame, and each inner pillar is used to insert into the inner side of the assembly body and abut against the inner side of the assembly body.

[0021] In one possible implementation, the assembly body has four reinforcing ribs on its inner side;

[0022] The four reinforcing ribs are respectively fixedly connected to the four corners of the assembly; each reinforcing rib has a snap-fit ​​groove on the side facing the central axis of the assembly, and the outer side of the inner support column has a protruding ridge suitable for embedding into the snap-fit ​​groove.

[0023] In one possible implementation, slots are provided at the ends of the assembled body, and the docking frame has reinforcing posts suitable for insertion into the slots.

[0024] In one possible implementation, there are four reinforcing columns spaced apart circumferentially along the docking frame; an adhesive strip is provided between two adjacent reinforcing columns along the docking frame, the adhesive strip being disposed on the end face of the docking frame and used to adhere to the end face of the assembled body.

[0025] In one possible implementation, each group of the assembled body corresponds to four enclosing bands, and the four enclosing bands are respectively arranged around the perimeter of the assembled body.

[0026] In this embodiment, multiple sets of assembled components form a truss corridor connecting two buildings; and the assembled components and buildings, as well as adjacent sets of assembled components, are connected by docking frames to replace the original direct contact and connection method, thereby improving the stability of the connection relationship.

[0027] When it is necessary to enclose the outer perimeter of the truss corridor, multiple enclosure strips are sequentially installed around the docking frame. Each time they are installed, adjacent enclosure strips are connected by a detachable connecting structure to ultimately form a cylindrical structure around the outer perimeter of the enclosed assembly. When it is necessary to unenclose the outer perimeter of the truss corridor, removing any set of detachable connecting structures will allow the cylindrical structure to open, thus enabling it to detach from the assembly and eliminating the need to operate on the other enclosure strips.

[0028] The temporary enclosed truss corridor structure provided in this embodiment, compared with the prior art, enables rapid closure and unclosure of the truss corridor, improving the efficiency of truss corridor installation and adjustment. Attached Figure Description

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0047] Please refer to the following: Figures 1 to 12 The temporary enclosed truss corridor structure provided in this application will now be described. The temporary enclosed truss corridor structure proposed in this application includes multiple sets of assembled bodies 1.

[0048] Multiple sets of assembly 1 are arranged between two buildings along a preset direction. Each set of assembly 1 uses a truss section made of I-beams and steel pipes. The structure formed by the combination of multiple sets of assembly 1 can connect the two buildings so that equipment such as belt conveyors can be placed in it.

[0049] Each assembly 1 has a docking frame 2 coaxially arranged at both ends. The internal space of the docking frame 2 is connected to the internal cavity of the assembly 1 to avoid interfering with the placement of the equipment. During actual installation, the assembly 1 located at the end is connected to the building through the docking frame 2 at the end away from the adjacent assembly 1. Two adjacent assemblies 1 are connected by a detachable connection combination of the two docking frames 2.

[0050] In this embodiment, each assembly body 1 also includes multiple enclosed strips 3; the multiple enclosed strips 3 are all arranged between two corresponding docking frames 2 and are spaced apart along the circumference of the assembly body 1.

[0051] When adjacent assembly bodies 1 are combined by two docking frames 2, both ends of each closed strip 3 are connected to the two docking frames 2 respectively. The two adjacent closed strips 3 along the circumference of the assembly body 1 are connected by a separable connection structure 4 to form a cylindrical structure on the outer circumference of the closed assembly body 1.

[0052] In this embodiment, multiple sets of assembled bodies 1 form a truss corridor connecting two buildings; and the assembled bodies 1 and the buildings, as well as the two adjacent sets of assembled bodies 1, are connected by docking frames 2, which replaces the original direct contact and connection method and improves the stability of the connection relationship.

[0053] When it is necessary to close the perimeter of the truss corridor, multiple closing strips 3 are sequentially arranged around the docking frame 2. Each time they are arranged, adjacent closing strips 3 are connected by a detachable connecting structure 4 to ultimately form a cylindrical structure around the perimeter of the closed assembly 1. When it is necessary to unclose the perimeter of the truss corridor, removing any set of detachable connecting structures 4 will allow the cylindrical structure to open, thus enabling it to detach from the assembly 1 and eliminating the need to operate on the other closing strips 3.

[0054] The temporary enclosed truss corridor structure provided in this embodiment, compared with the prior art, enables rapid closure and unclosure of the truss corridor, improving the efficiency of truss corridor installation and adjustment.

[0055] In some embodiments, such as Figure 12 As shown, the detachable connection structure 4 includes a hook and loop fastener face 41 and a loop and loop fastener face 42.

[0056] The Velcro hook face 41 is set on the side of one of the closed bands 3.

[0057] The hook and loop face 42 is disposed on the side of another closed band 3 and is used to engage with the hook and loop face 41 to connect the sides of the two closed bands 3.

[0058] It should be noted that, in order to avoid the hook and loop fastener face 41 and hook and loop fastener face 42 being externally located, which would cause the combined structure to be affected by external factors and shorten its service life, a recessed groove is provided on the sealing strip 3, and the corresponding hook and loop fastener face 41 or hook and loop fastener face 42 is set in the recessed groove so that after the two are attached, the hook and loop fastener face 41 and hook and loop fastener face 42 are located between the two sealing strips 3.

[0059] In some embodiments, such as Figures 10 to 12 As shown, the thickness of the sealing strip 3 alternately increases and decreases along its length direction to form multiple thick and thin sections that are alternately arranged.

[0060] Among them, the hook and loop face 41 and the loop and loop face 42 are both provided on the thick part; that is to say, the aforementioned separable connection structure 4 has multiple sets, and the multiple sets of separable connection structures 4 are provided one-to-one on multiple thick parts.

[0061] By adopting the above technical solution, firstly, the combined structure of the thick and thin sections enables a lightweight design for the closed strip 3. Secondly, since the thicker areas typically have more material deposited and stronger structural rigidity, they can provide a larger bonding area and supporting substrate for the hook and loop sections 41 and 42, preventing deformation or tearing of the base layer during repeated opening and closing. Furthermore, the thicker section can better disperse the shear or peeling forces (especially under dynamic loads) on the separable connection structure 4, reducing the risk of separation.

[0062] In some embodiments, such as Figure 11 and Figure 12 As shown, the side of the closed strip 3 has an outwardly curved bend 31, and two adjacent closed strips 3 along the circumference of the assembly body 1 are connected by two bends 31.

[0063] In this embodiment, both the hook and loop face 41 and the loop face 42 are provided on the inner side of the bend 31 to widen the hook and loop face 41 and ensure the strength and stability of the bonding structure.

[0064] In some embodiments, such as Figure 4 and Figure 5 As shown, the docking frame 2 has a reserved hole 21 that runs through the axial direction of the assembly body 1; in this embodiment, there are four reserved holes 21 on the docking frame 2, which are located at the four corners of the docking frame 2 respectively.

[0065] There are positioning screws 5 between two adjacent assembly bodies 1; in this embodiment, there are four positioning screws 5 between two adjacent assembly bodies 1, and they are inserted into four reserved holes 21 in a corresponding manner. Specifically, they are inserted into four sets of reserved holes 21, and each set of reserved holes 21 includes two reserved holes 21 that are coaxially connected (located on two docking frames 2 respectively).

[0066] The positioning screw 5 is adapted to be inserted into two interconnected pre-drilled holes 21, and after it is inserted into the two interconnected pre-drilled holes 21, both ends of the positioning screw 5 can extend to the two sides of the two mating frames 2 respectively.

[0067] Both ends of the positioning screw 5 are threaded with locking nuts 51; in actual use, each locking nut 51 is used to contact the outer surface of the docking frame 2 on the same side to connect the two docking frames 2 and restrict the relative movement of the two docking frames 2.

[0068] In some embodiments, such as Figure 6 and Figure 7 As shown, the inner side of the docking frame 2 has four inner support columns 22; the four inner support columns 22 are respectively connected to the four corners of the docking frame 2. Each inner support column 22 is used to insert into the inner side of the assembly body 1 and abut against the inner side of the assembly body 1, thereby improving the combined strength of the assembly body 1 and the docking frame 2, and thus improving the overall strength of the truss corridor.

[0069] In some embodiments, such as Figure 3 , Figure 8 and Figure 9 As shown, each assembly 1 has four reinforcing ribs 6 on its inner side.

[0070] Four reinforcing ribs 6 are fixedly connected to the four corners of the assembly body 1. Each reinforcing rib 6 has a snap-fit ​​groove 61 on the side facing the central axis of the assembly body 1. Specifically, the reinforcing rib 6 is an angle steel, and its two ends are aligned with the two ends of the assembly body 1, with the concave surface of the angle steel forming the snap-fit ​​groove 61. Based on this, the outer surface of the inner support column 22 has a protruding rib 221 suitable for embedding into the snap-fit ​​groove 61. Through the cooperation of the protruding rib 221 and the snap-fit ​​groove 61, the assembly body 1 and the docking frame 2 can be easily aligned.

[0071] In some embodiments, such as Figure 1 , Figure 4 and Figure 8 As shown, slots 11 are provided at the ends of the assembled body 1, and reinforcing columns 23 suitable for insertion into the slots 11 are provided on the docking frame 2. By inserting the reinforcing columns 23 into the slots 11, the combined strength of the assembled body 1 and the docking frame 2 can be improved, thereby improving the overall strength of the truss corridor.

[0072] In some embodiments, such as Figure 1 , Figure 4 and Figure 8 As shown, there are four reinforcing columns 23, which are spaced apart circumferentially along the docking frame 2; correspondingly, there are also four slots 11, located at corresponding positions on the end face of the assembly body 1. In this embodiment, the corner ends of the assembly body 1 adopt a steel pipe structure, with the inside of the steel pipe being hollow, to form slots 11 into which the reinforcing columns 23 can be inserted.

[0073] An adhesive tape 24 is provided between two adjacent reinforcing columns 23 along the docking frame 2. The adhesive tape 24 is provided on the end face of the docking frame 2 and is used to adhere to the end face of the assembly body 1, thereby completing the initial fixation of the assembly body 1 and the docking frame 2, so as to facilitate subsequent welding and fixation.

[0074] By adopting the above technical solution, the structural design of the four reinforcing columns 23 can avoid stress concentration, thereby improving the stability of the combined structure of the assembly 1 and the docking frame 2.

[0075] In some embodiments, such as Figure 1 and Figure 10 As shown, each assembly 1 corresponds to four closed bands 3. The four closed bands 3 are respectively set around the assembly 1 to form a square structure that fits the assembly 1. On the one hand, this avoids the rotation of the combined structure relative to the assembly 1, and on the other hand, it ensures the lightweight of the overall structure.

[0076] The above content is only a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
