Description

Technical Field

[0001] This invention relates to the field of civil engineering technology, specifically to a lightweight, high-strength, foldable, portable field tool shed. Background Technology

[0002] On-site tool sheds are double-layered protective sheds erected above woodworking areas, steel bar processing areas, or other locations where objects may fall or within the swing range of crane booms, to protect construction workers.

[0003] Currently, the on-site tool shed mainly uses steel pipes as the supporting frame, covered with a steel plate layer and a soft protective layer. Its erection and dismantling method is as follows: steel components are hoisted and welded on site, and dismantled by gas cutting and transported in bulk after use.

[0004] The existing tool shed has a large dismantling and assembly structure, and the dismantling and assembly methods not only increase the construction period and labor costs, but also have a high rate of dismantling losses and cumbersome on-site turnover.

[0005] Therefore, the existing tool sheds suffer from low construction efficiency due to their complex disassembly and assembly structures. It is evident that optimizing the disassembly and assembly structure of tool sheds to improve construction efficiency is a problem that needs to be solved in this field. Summary of the Invention

[0006] To address the technical problem of low construction efficiency caused by the complex assembly and disassembly structure of existing tool sheds, this solution aims to provide a foldable and portable tool shed. The tool shed has a foldable structure, which facilitates installation and disassembly. At the same time, this solution also provides a method for using the foldable and portable tool shed, which effectively overcomes the problems existing in the prior art.

[0007] To achieve the above objectives, the present invention provides a foldable portable tool shed, comprising several single-span canopy structures. Each single-span canopy structure includes a column, a canopy assembly, a pulley assembly, and a sealing plate. One end of the sealing plate is hinged to the third side of the column and can rotate back and forth relative to the column in a first direction, wherein the first rotation is an up-and-down rotation around the hinge. Adjacent sealing plates in the plurality of single-span canopy structures are detachably connected. The canopy assembly is symmetrically located on the first and second sides of the column and hinged to the column. The canopy assembly can rotate back and forth relative to the column in the first direction and can partially press against the sealing plate. Adjacent canopy assemblies in the plurality of single-span canopy structures are hinged together, and adjacent canopy assemblies can rotate relative to each other in a second direction, wherein the second rotation is a horizontal rotation around the hinge. The pulley assembly is fitted onto the end face of the second end of the column.

[0008] Furthermore, a sleeve is fitted onto the first end of the column and fixedly connected to the column. The first and second sides of the sleeve are respectively provided with a first hinge point and a second hinge point for connecting the ceiling assembly. The third side of the column is provided with a third hinge point for connecting the sealing plate.

[0009] Furthermore, the pulley assembly includes a pulley mounting base and a pulley. The pulley mounting base includes a column base steel plate and an internal steel pipe. The internal steel pipe is sleeved on the second end of the column and fixedly connected to the column. The column base steel plate is set at the bottom of the internal steel pipe to form a node structure connected to the pulley.

[0010] Furthermore, the foldable portable tool shed also includes a support component, the two ends of which are connected to the roof component and the uprights, respectively, to support the roof component.

[0011] Furthermore, the support assembly includes a first ear plate, a second ear plate, and a diagonal brace; the first ear plate is located at the bottom of the ceiling assembly and disposed on the side wall of the column, and the second ear plate is disposed at the bottom of the ceiling assembly; the two ends of the diagonal brace are detachably connected to the first ear plate and the second ear plate, respectively.

[0012] Furthermore, the canopy assembly includes three main beams, several longitudinal beams, and several top plates. The three main beams are connected to each other to form a rectangular frame. Several longitudinal beams are arranged inside the rectangular frame to form a grid structure. The grid structure is filled with top plates to form the canopy assembly.

[0013] Furthermore, a sealing strip is provided around the main beam of the canopy assembly.

[0014] To achieve the above objectives, the present invention provides a method for using a foldable portable tool shed, which is based on the above-described foldable portable tool shed configuration. The method for using the foldable portable tool shed includes operation steps in an unfolded state and a folded state.

[0015] Furthermore, the operation steps for the unfolded state include:

[0016] S1: Lay the tool shed flat and install pulleys at the bottom. After completion, stand the tool shed upright.

[0017] S2: Through the hinge structure between adjacent tool sheds, push and unfold along the longitudinal direction of the tool shed, and after fully unfolding into place, limit and fix the tool shed;

[0018] S3: Rotate the sealing plate upwards and fix the adjacent sealing plates using the locking mechanism;

[0019] S4: Use locking devices to fix the adjacent two spans of the ceiling structure, making them a whole under load;

[0020] S5: Rotate the canopy structure on both sides of the column upwards and install diagonal braces to fix the canopy structure. The tool shed is now fully unfolded.

[0021] Furthermore, the operation steps for the folded state include:

[0022] S1: Remove the diagonal bracing, rotate the ceiling structure downwards to a hanging state, and perform the first state folding of the ceiling;

[0023] S2: Unscrew the locking parts, rotate the sealing plate downwards to a hanging position, and fold the sealing plate in the first state;

[0024] S3: Unscrewing the locking parts releases the overall stress on the ceiling structure;

[0025] S4: Lay the tool shed flat and install pulleys at the bottom of the uprights;

[0026] S5: Erect the tool shed, fold the roof structure along its longitudinal direction, and fold the roof assembly into the second state. The tool shed folding is now complete.

[0027] The foldable portable tool shed and its usage method provided by the present invention form a detachable structure by detachably connecting adjacent tool sheds, which facilitates installation and disassembly and greatly improves construction efficiency. Attached Figure Description

[0041] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below with reference to specific illustrations.

[0042] In view of the technical problems of existing tool sheds, such as complicated on-site assembly and disassembly methods and high disassembly loss rate, the purpose of this invention is to provide a lightweight, high-strength, foldable, portable on-site tool shed. It can realize a foldable structure, which is convenient for on-site assembly and disassembly. Moreover, after disassembly, it can be folded and put into use for the next project, thereby improving utilization rate.

[0043] The lightweight, high-strength, foldable, portable field tool shed provided by this solution includes several single-span roof structures. These single-span roof structures can be unfolded and detachably connected by fasteners to form a prefabricated tool shed. After the fasteners are removed, the single-span roof structures can be folded and stored.

[0044] Further, see Figures 1-2 In this scheme, each single-span roof structure includes a column 100, a roof assembly 200, a pulley assembly 300, and a support assembly 400.

[0045] Furthermore, the column 100 serves as the support for the entire single-span ceiling structure, and its bottom is provided with a pulley assembly 300, which includes a pulley mounting seat 310 and a pulley 320.

[0046] The pulley mounting base 310 includes an inner steel square tube 311 and a column base steel plate 312. The inner steel square tube 311 is sleeved on the bottom end of the column 100 and fixedly connected to the column 100, which can form a protective structure for the column base of the column 100. The column base steel plate 312 is set at the bottom of the inner steel square tube 311 to form the installation node of the pulley 320.

[0047] The pulley assembly 300 is installed at the bottom of the column 100 to form the walking assembly of this tool shed, which can adjust the position of this tool shed.

[0048] The fixed connection structure between the inner steel square tube 311, the column base steel plate 312, and the pulley is not limited in this scheme. Welding is preferred in this scheme, which can ensure the stability of the fixed connection between each component and further improve the strength of this tool shed.

[0049] See Figure 3 Each column 100 is fitted with a steel sleeve 130 at its top, which can form a protective structure for the column head of the column 100. The steel sleeve 130 has a first hinge point 110 and a second hinge point 120 on both sides. The first hinge point 110 and the second hinge point 120 are respectively used for setting the canopy assembly 200. The canopy assembly 200 is hinged to the column 100, so that the canopy assembly 200 can rotate axially in the Y and Z axes relative to the two sides of the column 100 in the three-dimensional coordinate axis.

[0050] When the canopy assembly 200 rotates axially relative to both sides of the column 100, it can be folded and unfolded in the first direction relative to the column 100, realizing the unfolding and folding of the tool shed in the first state.

[0051] Further, see Figure 4 ,- Figure 5 The roof assembly 200 includes three main beams 210, several longitudinal beams 220 and several roof plates 230. The three main beams 210 are connected to each other to form a rectangular frame. Several longitudinal beams 220 are set inside the rectangular frame to form a grid structure. At the same time, the roof plates 230 are arranged in the grid structure to form the roof assembly.

[0052] The connection structure between the main beam 210, longitudinal beam 220 and top plate 230 is not limited in this scheme. For example, it can be glued or welded. The specific structure can be selected according to the actual situation.

[0053] When the canopy assembly 200 is unfolded relative to the column 100, since the canopy assembly 200 and the column 100 are hinged, a support assembly 400 is provided between the canopy assembly 200 and the column 100 to support the unfolded state of the canopy assembly 200.

[0054] See Figure 6The support component 400 is disposed opposite to both sides of the column 100 and the canopy components 200 on both sides of the column 100. The support component 400 includes a first ear plate 410, a second ear plate 420 and a diagonal brace 430.

[0055] The first ear plate 410 is located at the bottom of the canopy assembly 200 and is disposed on the side wall of the column 100. The second ear plate 420 is disposed at the bottom of the canopy assembly 200. The first ear plate 410 and the second ear plate 420 are connected by a diagonal brace 430, thereby forming a stable triangular structure with the canopy assembly 200 and the column 100, which can fix and support one end of the canopy assembly 200. When the canopy assembly 200 needs to be folded, the diagonal brace 430 can be manually removed.

[0056] A tool shed can be formed by assembling several of the above-mentioned foldable single-span canopy structures together. For example, in specific applications:

[0057] See Figure 7 When the canopy assembly 200 needs to be folded, the diagonal brace 430 is disassembled, and the canopy assemblies 200 on both sides of the column 100 are reversed downward relative to the column through the hinge structure to perform the first state of folding.

[0058] When the canopy assembly 200 needs to be unfolded, the canopy assemblies 200 on both sides of the column 100 are reversed upward along the hinge points on both sides of the column 100 until the critical value is reached. Then, diagonal braces 430 are set between the ear plates on the column 100 and the canopy assembly 200 to fix them, forming the unfolding structure of the canopy structure.

[0059] Furthermore, by setting locking members 250 between the ends of adjacent canopy components 200, the adjacent canopy components 200 can be connected, so that the two adjacent spans of canopy components 200 become a force-bearing whole, supporting each other, and completing the assembly structure of the tool shed in the unfolded state.

[0060] Also see Figure 5 Sealing strips 260 can be preferably installed on the main beams 210 of adjacent roof components 200 to ensure that the two adjacent roof components 200 fit tightly when in use, preventing rainwater from leaking between the two roof components 200.

[0061] Furthermore, the canopy components 200 in adjacent single-span structures are hinged together by setting a hinge structure, which can connect several single-span canopy structures to form an integral structure. At the same time, the adjacent canopy components 200 can be folded into a second state by the hinge structure.

[0062] For details, see Figures 8-10Adjacent single-span ceiling components 200 are connected by a hinge structure, and the two span ceiling components can rotate relative to each other in the X and Z axes, realizing relative folding and unfolding between adjacent ceiling components 200.

[0063] Furthermore, when the canopy components 200 on both sides of the column 100 are unfolded relative to each other, there will be a gap in the middle, which can easily cause rainwater leakage. Therefore, in the single-span canopy structure, a sealing plate 500 is installed between the canopy components 200 on both sides of the column 100.

[0064] Specifically, the other side of the column 100 is provided with a third hinge point 140, which is located below the first hinge point 110 and the second hinge point 120. It is used to hinge with the sealing plate 500. The sealing plate 500 can rotate relative to the column in the X and Z axes, so as to realize the folding and unfolding of the sealing plate 500 relative to the column 100.

[0065] Meanwhile, the sealing plate 500 is wider than the cross-sectional width of the column 100. The sealing plate 500 is located below the two side canopy components 200. When the two side canopy components 200 are unfolded, they can partially press on the sealing plate 500. The sealing plate 500 can fill the gap in the middle to prevent rainwater leakage.

[0066] After the canopy components 200 of two adjacent spans are assembled, the sealing plate 500 is flipped upward along the column 100 and connected to the sealing plate 500 of the canopy components 200 of the two adjacent spans through the locking member 510, thus completing the assembly of the overall tool shed; during disassembly and assembly, the locking member 510 is manually removed, and the sealing plate 500 can be flipped downward relative to the column 100 to fold the sealing plate 500.

[0067] This solution does not limit the hinge structure between the components in the entire tool shed. For example, it can be a hinge, a self-locking hinge, etc. The specific application can be determined according to the actual situation.

[0068] Meanwhile, the materials of the columns 100, the canopy components 200, the sealing plates 500, and the diagonal braces 430 are not limited in this solution. This solution preferably uses glass fiber pultrusion molding, which is a high-performance composite material GFRP. It is an inorganic non-metallic material with excellent performance, good insulation, strong heat resistance, good corrosion resistance, and high strength.

[0069] Secondly, its density is one-quarter that of steel, and its strength is about four times that of steel, making it a potential new building material that can drive the industry's green and low-carbon transformation.

[0070] Based on the lightweight, high-strength, foldable, portable field tool shed constructed using the above solution, this solution also provides methods for using the foldable, portable field tool shed, including folded and unfolded forms. The usage steps for different forms are as follows:

[0071] (1) Unfolding steps:

[0072] S1: Lay the tool shed flat and install magnetic pulleys 320 on the bottom column base steel plate 312. After completion, stand the tool shed upright.

[0073] S2: Through the hinge structure 240 between adjacent tool sheds, push along the longitudinal direction of the tool shed (first span unfolds → second span unfolds → third span unfolds), and fix it with anchor bolts after it is fully unfolded to limit the displacement of the tool shed;

[0074] S3: Rotate the sealing plate 500 upwards to 90° with the column, and fix the adjacent sealing plate 500 with bolts;

[0075] S4: Use fixed anchor plates and expansion bolts to fix the roof structure of two adjacent spans, making it a whole load-bearing structure;

[0076] S5: Rotate the canopy components 200 on both sides of the column 100 upwards to form a 90° angle with the column, and install the diagonal brace 430 to fix the canopy structure. The tool shed is now fully unfolded.

[0077] (2) Folding steps:

[0078] S1: Remove the diagonal brace 430, rotate the roof assembly 200 downwards by 90° to a hanging position, and perform the first state folding of the roof;

[0079] S2: Unscrew bolt 510, rotate sealing plate 500 downwards 90° to a hanging position, and fold sealing plate 500 in the first state;

[0080] S3: Unscrew the expansion bolts, remove the fixing anchor plates, and relieve the overall stress on the ceiling structure;

[0081] S4 The tool shed is laid flat, and magnetic pulleys 320 are installed on the steel plate 312 of the column base;

[0082] S5 Erect the tool shed and fold the canopy structure along its longitudinal direction (fold the 3rd span → fold the 2nd span → fold the 1st span), fold the canopy assembly 200 into the second state, and the tool shed is folded.

[0083] The above-described foldable portable tool shed and its usage method are described. The tool shed in this solution is a foldable structure, which can fold the canopy component into two states. When fully folded, it is small in size, easy to transport and store, and when unfolded, it can cover three-dimensional space and maintain normal working condition.

[0084] At the same time, it can improve the functionality of on-site tool sheds, reduce transport size and weight without significantly increasing costs, and facilitate transportation and storage.

[0085] Secondly, its prefabricated structure reduces installation time and disassembly labor during on-site application, saving time and labor costs.

[0086] Finally, the tower crane is used only once for installation, turnover, and dismantling, improving the utilization rate of the lifting equipment; after dismantling, it can be folded and used for the next project, improving utilization rate.

[0087] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention.
