Description

Technical Field

[0001] This invention relates to the field of bulletproof structures, specifically to a foldable constraint structure for bulletproof structures and a bulletproof structure. Background Technology

[0002] The construction of critical protective facilities is becoming increasingly sophisticated. Some facilities employ yaw structures and high-strength materials for bulletproofing, which, while providing significant protection, are also very expensive. Steel-confined concrete is another practical bulletproofing technology with advantages such as high load-bearing capacity, good ductility, and convenient construction. It has been widely used in bridge pier construction, mine reinforcement, and other fields. By using the clamping effect of the steel pipe wrapped around the concrete, it puts the concrete in a triaxial stress state, limiting concrete cracking. At the same time, the filling and supporting effect of the concrete limits the internal buckling deformation of the steel pipe, thus exhibiting excellent ballistic resistance.

[0003] The process of steel-tube confined concrete includes the cutting, bending, and welding of raw materials, as well as the pouring of concrete. However, due to the limitations of transportation, the steel pipes in existing steel-tube confined concrete structures can only be produced as semi-finished products in the factory (completing the cutting, bending, and welding processes of limited dimensions). On the construction site, secondary welding is still required (welding the walls of the semi-finished steel pipes together) before pouring concrete. It is evident that existing steel-tube confined concrete structures have the disadvantages of being inconvenient to transport and difficult to modularize and mass-produce.

[0004] Therefore, there is a need for a foldable constraint structure for bulletproof structures that is easy to transport and can be modularly mass-produced. Summary of the Invention

[0005] The purpose of this invention is to provide a foldable constraint structure for bulletproof structures that is easy to transport and can be modularly mass-produced.

[0006] To achieve the above objectives, the present invention provides a foldable constraint structure for a bulletproof structure. The constraint structure includes a constraint component, a connecting component, and a limiting component. The constraint component and the connecting component are deformably connected to form a plurality of constraint units capable of deforming between an unfolded state and a folded state. Each constraint unit is provided with a filling cavity for filling material, the shape of which corresponds to the shape of the constraint unit. The limiting component is used to detachably connect the constraint component and / or the connecting component. When the limiting component connects the constraint component and / or the connecting component, the shapes of the constraint component and the connecting component are limited, and the constraint unit is limited to the unfolded state. When the limiting component is separated from the constraint component and / or the connecting component, the shapes of the constraint component and the connecting component can change, and the constraint unit can deform between the unfolded state and the folded state.

[0007] Furthermore, in the unfolded state, both the constraint unit and the filling cavity are regular prisms.

[0008] Furthermore, the constraint component includes a plurality of first constraint members, and the connection component includes a plurality of first connectors. The plurality of first constraint members and the plurality of first connectors are deformably connected together to form a plurality of constraint units.

[0009] Furthermore, the first constraint member includes a first body and first connecting structures respectively disposed at both ends of the first body. The first connecting structure is provided with a pivot connecting hole. The first connector includes a plurality of second connecting structures and a plurality of pivot shafts respectively connected to the plurality of second connecting structures. The pivot shafts are pivotable relative to each other and pass through the pivot connecting holes one by one.

[0010] Furthermore, the constraint assembly also includes a plurality of second constraint members, the plurality of first constraint members, the plurality of second constraint members and the plurality of first connectors can be deformably connected to form a plurality of constraint units, and the second connection structure is provided with a first connection portion for connecting with the second constraint members.

[0011] Furthermore, the limiting component includes a limiting member and a plurality of first snap-fit ​​structures disposed on the limiting member, and the second connecting structure is provided with a second snap-fit ​​structure corresponding to the first snap-fit ​​structure.

[0012] Furthermore, the second connecting structure is provided with a plurality of mounting holes for fastening a plurality of the pivot shafts in a one-to-one correspondence, and the plurality of pivot shafts pass through the plurality of mounting holes in a one-to-one correspondence and are fastened to the second connecting structure.

[0013] Furthermore, the constraint structure also includes a first constraint limiting member and a second constraint limiting member. One end of the first constraint limiting member is used to detachably connect to the first snap-fit ​​structure, and the other end of the first constraint limiting member is pivotable relative to and connected to the pivot shaft in a one-to-one correspondence. Both ends of the second constraint limiting member are pivotable relative to and connected to the respective pivot shafts of the two first connecting members in a one-to-one correspondence.

[0014] Furthermore, the first connector includes a plurality of second connecting structures and a plurality of pivot shafts that are respectively parallel to each other and fastened to the plurality of second connecting structures. The plurality of second connecting structures are evenly spaced along the axial direction of the pivot shafts, and the first connecting structure is evenly spaced with a plurality of clearance grooves for accommodating the plurality of second connecting structures.

[0015] Furthermore, the present invention also provides a bullet shielding structure, the bullet shielding structure comprising the folded constraint structure for bullet shielding described in the present invention and filler filling the plurality of filling cavities in the constraint structure.

[0016] The foldable constraint structure for bulletproof structures of the present invention includes a constraint component, a connecting component, and a limiting component. The constraint component and the connecting component are deformably connected as a single unit to form multiple constraint units capable of deforming between an unfolded state and a folded state. Each constraint unit is provided with a filling cavity for filling material, the shape of which corresponds to the shape of the constraint unit. The limiting component is used to detachably connect the constraint component and / or the connecting component. When the limiting component is connected to the constraint component and / or the connecting component, the shapes of the constraint component and the connecting component are limited, and the constraint unit is limited to an unfolded state. When the limiting component is separated from the constraint component and / or the connecting component, the shapes of the constraint component and the connecting component can change, and the constraint unit can deform between an unfolded state and a folded state. Therefore, the foldable constraint structure for bulletproof structures of the present invention can be modularly mass-produced in a factory, with constraint components, connecting components, and limiting components manufactured as a single unit. The constraint components and connecting components are then assembled into a single unit. The limiting component, along with the assembled constraint components and connecting components in a folded state, are transported to the construction site. At the construction site, the assembled constraint components and connecting components are unfolded so that the constraint units are in an unfolded state. Subsequently, the limiting component is connected to the constraint components and / or connecting components to limit the constraint units to an unfolded state. Finally, filler is filled into the multiple filling cavities of the constraint structure. It can be seen that the foldable constraint structure for bulletproof structures of the present invention has the advantages of easy transportation and modular mass production.

[0017] The bullet shielding structure of the present invention, since it includes the folded constraint structure of the present invention for bullet shielding structure, also has the above-mentioned advantages of the constraint structure of the present invention.

[0045] The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0046] This invention provides a foldable constraint structure for bulletproof structures, specifically, as follows: Figures 1 to 7As shown, the constraint structure includes a constraint component, a connecting component, and a limiting component. The constraint component and the connecting component are deformably connected to form multiple constraint units that can deform between an unfolded state and a folded state. Each constraint unit is provided with a filling cavity 1 for filling filler. The shape of the filling cavity 1 corresponds to the shape of the constraint unit. The limiting component is used to detachably connect the constraint component and / or the connecting component. When the limiting component connects the constraint component and / or the connecting component, the shapes of the constraint component and the connecting component are limited, and the constraint unit is limited to the unfolded state. When the limiting component is separated from the constraint component and / or the connecting component, the shapes of the constraint component and the connecting component can change, and the constraint unit can deform between the unfolded state and the folded state.

[0047] The foldable constraint structure for bulletproof structures of the present invention includes a constraint component, a connecting component, and a limiting component. The constraint component and the connecting component are deformably connected as a single unit to form multiple constraint units capable of deforming between an unfolded state and a folded state. Each constraint unit is provided with a filling cavity 1 for filling filler, the shape of which corresponds to the shape of the constraint unit. The limiting component is used to detachably connect the constraint component and / or the connecting component. When the limiting component is connected to the constraint component and / or the connecting component, the shapes of the constraint component and the connecting component are limited, and the constraint unit is limited to an unfolded state. When the limiting component is separated from the constraint component and / or the connecting component, the shapes of the constraint component and the connecting component can change, and the constraint unit can deform between an unfolded state and a folded state. Therefore, the foldable constraint structure for bulletproof structures of the present invention can be modularly mass-produced in a factory, and the constraint component, connecting component, and limiting component can be manufactured in large quantities. The binding assembly and connecting assembly are assembled into one unit. Then, the limiting assembly, the binding assembly and connecting assembly assembled into one unit with the binding unit in a folded state, are transported to the construction site. At the construction site, the binding assembly and connecting assembly are unfolded so that the binding unit is in an unfolded state. Subsequently, the limiting assembly is connected to the binding assembly and / or connecting assembly to limit the binding unit to an unfolded state. Finally, filler is filled into the multiple filling cavities 1 of the binding structure. It can be seen that the folding binding structure for bulletproof structures of the present invention has the following advantages: 1. It is easy to transport and can be assembled on site. The assembly is convenient and efficient. 2. When some parts of the structure are damaged, they can be replaced modularly, which is conducive to rapid repair and cost saving. 3. It can be mass-produced modularly. 4. It reduces the amount of material used (the welding parts of adjacent steel pipes in existing steel pipe-confined concrete overlap, so the binding structure of the present invention uses more material than that of the present invention), thus reducing costs.

[0048] It should be noted that the specific structural forms of the aforementioned constraint components, connecting components, limiting components, constraint units, and filling cavity 1, as well as the specific materials used to manufacture the constraint components, connecting components, and limiting components, can all be set as needed, and these all fall within the scope of the technical concept of this invention. The specific forms of the above features will be illustrated below by way of specific embodiments.

[0049] In the folding constraint structure for bulletproof structures of the present invention, preferably, in the unfolded state, both the constraint unit and the filling cavity 1 are regular prisms (e.g., regular triangular prisms, such as...). Figure 11 and 12 (e.g., regular square prism, regular hexagonal prism, etc.) to improve the structural strength of the folding constraint structure for bulletproof structures of the present invention in the unfolded state.

[0050] In the aforementioned folded constraint structure used for bulletproof structures, specifically, as follows: Figure 2 and 3 As shown, the constraint assembly includes multiple first constraint members 2, and the connection assembly includes multiple first connectors 3. The multiple first constraint members 2 and the multiple first connectors 3 are deformably connected to form a single unit and a plurality of constraint units. More specifically, the first constraint member 2 includes a first body 21 (e.g., a plate-like structure made of metal or composite material) and first connecting structures 22 respectively disposed at both ends of the first body 21. The first connecting structure 22 is provided with a pivoting connection hole penetrating itself. The first connector 3 includes multiple second connecting structures 31 and multiple pivot shafts 32 respectively connected to the multiple second connecting structures 31. The pivot shafts 32 are pivotable relative to each other and pass through the pivoting connection holes one by one. Thus, by connecting the first body 21, the first connecting structure 22, the multiple second connecting structures 31 and the multiple pivot shafts 32 into a single unit, a plurality of constraint units that can deform between an unfolded state and a folded state are realized.

[0051] In the aforementioned folded constraint structure used for bulletproof structures, more specifically, as follows: Figures 2 to 4 As shown, the constraint assembly also includes multiple second constraint members 4 (e.g., plate-like structures made of metal or composite materials). Multiple first constraint members 2, multiple second constraint members 4, and multiple first connecting members 3 are deformably connected together to form multiple constraint units. The second connecting structure 31 is provided with a first connecting portion 311 for fastening to the second constraint members 4. More specifically, the first connecting portion 311 is a groove, and the second constraint members 4 are welded to the first connecting portion 311.

[0052] In the aforementioned folded constraint structure used for bulletproof structures, more specifically, as follows: Figure 2 , Figure 3 and Figure 5As shown, the limiting component includes multiple limiting members 5 (e.g., plate-like structures made of metal or composite materials) and multiple first snap-fit ​​structures 6 disposed on the limiting members 5. The second connecting structure 31 is provided with a second snap-fit ​​structure 312 corresponding to the first snap-fit ​​structure 6, thereby limiting the constraint unit to an unfolded state by snap-fitting the first snap-fit ​​structure 6 and the second snap-fit ​​structure 312. More specifically, the first snap-fit ​​structure 6 is a snap-fit ​​protrusion or a snap-fit ​​groove, and the second snap-fit ​​structure 312 is a snap-fit ​​groove or a snap-fit ​​protrusion.

[0053] In the aforementioned folded constraint structure used for bulletproof structures, more specifically, as follows: Figure 4 and Figure 5 As shown, the second connecting structure 31 is provided with a plurality of mounting holes 313 for fastening a plurality of pivot shafts 32 in a one-to-one correspondence. The plurality of pivot shafts 32 pass through the plurality of mounting holes 313 in a one-to-one correspondence and are fastened to the second connecting structure 31. The first connecting part 311, the second snap-fit ​​structure 312 and the plurality of mounting holes 313 are evenly distributed on the second connecting structure 31.

[0054] It should be noted that the specific shapes of the constraint unit and the filling cavity 1 in the unfolded state depend on the number and size of the first constraint member 2 and the first connecting member 3 included in a constraint unit, the number of mounting holes 313 provided on the second connecting structure 31, and the number of pivot shafts 32 included in the first connecting member 3. For example, when both the constraint unit and the filling cavity 1 in the unfolded state are regular hexagonal prisms, the constraint unit is composed of six first constraint members 2 and six first connecting members 3 connected sequentially, the second connecting structure 31 is provided with three mounting holes 313, and the first connecting member 3 includes three pivot shafts 32. The second embodiment of the present invention described later belongs to the above situation.

[0055] In this invention Figures 1 to 7 In the first embodiment, both the constraint unit and the filling cavity 1 are regular hexagonal prisms in the unfolded state. Since the second connecting structure 31 is fastened to the second constraint member 4 through the first connecting part 311, the first connecting member 3 only includes two pivot shafts 32. The second connecting structure 31 is provided with only two mounting holes 313 and one first connecting part 311 or one second snap-fit ​​structure 312. The constraint unit is composed of four first constraint members 2, two second constraint members 4 and six first connecting members 3 connected in sequence. Among them, one of the first connecting part 311 and the second snap-fit ​​structure 312 and the multiple mounting holes 313 are evenly distributed on the second connecting structure 31.

[0056] In the aforementioned folded constraint structure used for bulletproof structures, more specifically, as follows: Figure 2 , Figure 3 and Figure 6 and Figure 7As shown, the constraint structure also includes a first constraint limiting member 7 and a second constraint limiting member 8. One end of the first constraint limiting member 7 is detachably connected to the first snap-fit ​​structure 6, and the other end of the first constraint limiting member 7 is pivotally connected to the pivot shaft 32. Both ends of the second constraint limiting member 8 are pivotally connected to the pivot shaft 32 of the two first connecting members 3, respectively. Thus, the folding constraint structure for bulletproof structures of the present invention can be completely constrained by the limiting member 5, the second snap-fit ​​structure 312, the first constraint limiting member 7, and the second constraint limiting member 8, preventing it from deforming. More specifically, as... Figure 6 As shown, the first constraint member 7 includes a second body 71 (e.g., a plate-like structure made of metal or composite material), a third snap-fit ​​structure 72 disposed at one end of the second body 71, and a third connecting structure 73 disposed at the other end of the second body 71. The third connecting structure 73 is provided with a pivoting connection hole penetrating itself. The third snap-fit ​​structure 72 is used to detachably snap-fit ​​the first snap-fit ​​structure 6. The third connecting structure 73 is pivotable relative to and correspondingly connected to the pivot shaft 32. Figure 7 As shown, the second constraint member 8 includes a third body 81 (e.g., a plate-like structure made of metal or composite material) and a fourth connecting structure 82 respectively disposed at both ends of the third body 81. The fourth connecting structure 82 is provided with a pivoting connecting hole that passes through itself. The fourth connecting structure 82 can pivot relative to each other and is connected to the pivot shaft 32 of each of the two first connecting members 3 in a one-to-one correspondence.

[0057] In the above-mentioned folding constraint structure for bulletproof structure, more specifically, the first connector 3 includes a plurality of second connecting structures 31 and a plurality of pivot shafts 32 that are respectively parallel to each other and fastened to the plurality of second connecting structures 31. The plurality of second connecting structures 31 are evenly spaced along the axial direction of the pivot shafts 32. The first connecting structure 22, the third connecting structure 73 and the fourth connecting structure 82 are evenly spaced with a plurality of clearance grooves for accommodating the plurality of second connecting structures 31.

[0058] It should be noted that the specific structural form of the folding constraint structure for bulletproof structures of the present invention is not limited to the above specific forms. The following will use the second embodiment as an example to illustrate the specific form of the present invention.

[0059] like Figures 8 to 10As shown, the foldable constraint structure for bulletproof structures of the present invention includes a constraint component, a connecting component, and a limiting component. The constraint component and the connecting component are deformably connected to form a plurality of constraint units that can deform between an unfolded state and a folded state. Each constraint unit is provided with a filling cavity 1 for filling filler. The shape of the filling cavity 1 corresponds to the shape of the constraint unit. The limiting component is used to detachably connect the constraint component and / or the connecting component. When the limiting component connects the constraint component and / or the connecting component, the shapes of the constraint component and the connecting component are limited, and the constraint unit is limited to the unfolded state. When the limiting component is separated from the constraint component and / or the connecting component, the shapes of the constraint component and the connecting component can change, and the constraint unit can deform between the unfolded state and the folded state.

[0060] The foldable constraint structure for bulletproof structures of the present invention includes a constraint component, a connecting component, and a limiting component. The constraint component and the connecting component are deformably connected as a single unit to form multiple constraint units capable of deforming between an unfolded state and a folded state. Each constraint unit is provided with a filling cavity 1 for filling filler, the shape of which corresponds to the shape of the constraint unit. The limiting component is used to detachably connect the constraint component and / or the connecting component. When the limiting component is connected to the constraint component and / or the connecting component, the shapes of the constraint component and the connecting component are limited, and the constraint unit is limited to an unfolded state. When the limiting component is separated from the constraint component and / or the connecting component, the shapes of the constraint component and the connecting component can change, and the constraint unit can deform between an unfolded state and a folded state. Therefore, the foldable constraint structure for bulletproof structures of the present invention can be modularly mass-produced in a factory, and the constraint component, connecting component, and limiting component can be manufactured in a large quantity. The components and connecting components are assembled into one unit. Then, the limiting component, the constraint component and the connecting component assembled into one unit with the constraint unit in a folded state are transported to the construction site. Next, at the construction site, the assembled constraint component and connecting component are unfolded so that the constraint unit is in an unfolded state. Then, the limiting component is connected to the constraint component and / or the connecting component to limit the constraint unit to an unfolded state. Finally, the filler is filled into the multiple filling cavities 1 of the constraint structure. It can be seen that the folded constraint structure for bulletproof structures of the present invention has the following advantages: 1. It is easy to transport and can be assembled on site. The assembly is convenient and efficient. 2. When some parts of the structure are damaged, they can be replaced modularly, which is conducive to rapid repair and cost saving. 3. It can be mass-produced modularly. 4. It reduces the amount of material used (the welding parts of adjacent steel pipes in existing steel pipe confined concrete overlap, so the constraint structure of the present invention uses more material than that of the present invention), thus reducing costs.

[0061] It should be noted that the specific structural forms of the aforementioned constraint components, connecting components, limiting components, constraint units, and filling cavity 1, as well as the specific materials used to manufacture the constraint components, connecting components, and limiting components, can all be set as needed, and these all fall within the scope of the technical concept of this invention. The specific forms of the above features will be illustrated below by way of specific embodiments.

[0062] In the folding constraint structure for bulletproof structures of the present invention, preferably, in the unfolded state, both the constraint unit and the filling cavity 1 are regular prisms (e.g., regular triangular prisms, such as...). Figure 11 and 12 (e.g., regular square prism, regular hexagonal prism, etc.) to improve the structural strength of the folding constraint structure for bulletproof structures of the present invention in the unfolded state.

[0063] In the aforementioned folded constraint structure used for bulletproof structures, specifically, as follows: Figure 9 As shown, the constraint assembly includes multiple first constraint members 2, and the connection assembly includes multiple first connectors 3. The multiple first constraint members 2 and the multiple first connectors 3 are deformably connected to form a single unit and a plurality of constraint units. More specifically, the first constraint member 2 includes a first body 21 (e.g., a plate-like structure made of metal or composite material) and first connecting structures 22 respectively disposed at both ends of the first body 21. The first connecting structure 22 is provided with a pivoting connection hole penetrating itself. The first connector 3 includes multiple second connecting structures 31 and multiple pivot shafts 32 respectively connected to the multiple second connecting structures 31. The pivot shafts 32 are pivotable relative to each other and pass through the pivoting connection holes one by one. Thus, by connecting the first body 21, the first connecting structure 22, the multiple second connecting structures 31 and the multiple pivot shafts 32 into a single unit, a plurality of constraint units that can deform between an unfolded state and a folded state are realized.

[0064] In the aforementioned folded constraint structure used for bulletproof structures, more specifically, as follows: Figure 9 and Figure 10 As shown, the limiting component includes multiple limiting members 5 and multiple first snap-fit ​​structures 6 disposed on the limiting members 5. The first body 21 is provided with a fourth snap-fit ​​structure 23 corresponding to the first snap-fit ​​structure 6, thereby limiting the constraint unit to an unfolded state by snap-fitting the first snap-fit ​​structure 6 and the fourth snap-fit ​​structure 23. More specifically, the limiting member 5 is formed to limit the first constraint member 2 and the first connecting member 3 around the part where the multiple first constraint members 2 are pivotally connected by the first connecting member 3. The first snap-fit ​​structure 6 is a snap-fit ​​protrusion or a snap-fit ​​groove, and the fourth snap-fit ​​structure 23 is a snap-fit ​​groove or a snap-fit ​​protrusion.

[0065] In the aforementioned folded constraint structure used for bulletproof structures, more specifically, as follows: Figure 10As shown, the second connecting structure 31 is provided with a plurality of mounting holes 313 for fastening a plurality of pivot shafts 32 in a one-to-one correspondence. The plurality of pivot shafts 32 pass through the plurality of mounting holes 313 in a one-to-one correspondence and are fastened to the second connecting structure 31. The plurality of mounting holes 313 are evenly distributed on the second connecting structure 31.

[0066] In the above-mentioned folding constraint structure for bulletproof structure, more specifically, the first connector 3 includes a plurality of second connecting structures 31 and a plurality of pivot shafts 32 that are respectively parallel to each other and fastened to the plurality of second connecting structures 31. The plurality of second connecting structures 31 are evenly spaced along the axial direction of the pivot shafts 32. The first connecting structure 22 is evenly spaced with a plurality of clearance grooves for accommodating the plurality of second connecting structures 31.

[0067] It should be noted that the specific structural form or shape and size of the first constraint member 2, the first connector 3, the second constraint member 4, the limiting member 5, the first constraint limiting member 7 and the second constraint limiting member 8, as well as the specific materials used to manufacture the first constraint member 2, the first connector 3, the second constraint member 4, the limiting member 5, the first constraint limiting member 7 and the second constraint limiting member 8, can all be set as needed, and these all fall within the scope of the technical concept of the present invention.
