Abstract

Simple sheds installed on farmland and other similar areas had a problem: their outer walls would sway violently in strong winds, posing a high risk of collapse or being blown away. Furthermore, there was a lack of shed structures that allowed for changes in the outer wall configuration to accommodate seasonal thermal conditions, and that were easy to install and remove. [Solution] A prefabricated shed that can be installed adjacent to the main body of the storage shed 1 has a prefabricated roof 2 and employs a three-layer exterior wall structure consisting of an outer mesh fence 8, a curtain, and inner mesh fences 11 and 12. The outer mesh fence 8 disperses the wind, the wind pressure is released by the wind-venting flaps provided on the outer wall of the curtain, and the wind intrusion into the interior is suppressed by the inner mesh fences 11 and 12, thereby gradually reducing the wind pressure acting on the exterior wall. Furthermore, the curtain is suspended along a rail 9 provided on the top of the shed so as to be able to move freely and can be replaced with a mosquito net-like curtain or a vinyl curtain without using tools.

[0003]

[0001] The present invention relates to a prefabricated hut that can be installed adjacent to a storage body installed on farmland or the like. In particular, the present invention relates to a prefabricated hut having a wind-resistant structure with an outer wall structure that can safely be used even in a strong wind environment while having a simple assembly structure and that gradually attenuates wind pressure from the outside to the inside.

Background Art

[0002] In farmland and the like, storages for storing agricultural implements, fertilizers, and the like are widely used. In addition, for farmers to take breaks and perform light work, simple huts or tents may be installed adjacent to the storages. However, farmland is an environment where there are few surrounding buildings or windbreak structures and is easily affected by strong winds such as typhoons and seasonal winds. Therefore, in general simple tents and cloth huts, there has been a problem that the outer wall swings greatly due to the wind, which not only gives users a sense of unease but also poses risks such as collapse, scattering, and damage. <00,00010>

[0003] [[ID=,16]]In addition, when trying to ensure wind resistance by constructing the outer wall with a highly rigid plate material or the like, the wind pressure directly acts on the outer wall, easily causing a large load on the entire structure, requiring enlargement of members and strengthening of the foundation, resulting in complicated installation and construction and an increase in cost. Furthermore, there has also been a risk that the working environment in summer deteriorates due to a decrease in air permeability.

Summary of the Invention

Problems to be Solved by the Invention

[0006] The present invention (1) Exterior wall structure that can be used safely even in strong wind conditions, (2) Flexibility to change the exterior wall configuration according to the season, (3) Easy assembly for installation and removal The objective is to provide a prefabricated shed equipped with a wind-resistant structure that also incorporates the following features.

[0007] Conventional work tents and temporary shelters are lightweight and inexpensive, but in environments with few windbreaks, such as farmland, the outer walls sway violently in strong winds, posing a high risk of collapse or being blown away. Furthermore, attempting to ensure wind resistance by constructing the outer walls solely from highly rigid members results in wind pressure directly acting on the walls, placing a significant load on the entire structure. This necessitates larger members and reinforced foundations, compromising ease of installation and removal, and presenting challenges in terms of constructability and cost.

[0008] Furthermore, in order to cope with the hot summer and cold winter environments, it is desirable to change the exterior wall materials according to the season. However, conventional simple sheds were not designed with exterior wall material replacement in mind, and replacement often required work such as removing fasteners, making it difficult to carry out. As a result, there was a problem in that it was not possible to adequately provide an environment in which agricultural workers could work and rest comfortably.

[0009] In view of these problems, the present invention aims to provide a prefabricated shed that has a three-layer exterior wall structure that gradually reduces wind pressure from the outside to the inside, can be used safely even in strong winds, has an exterior wall configuration that can be flexibly changed according to the season and purpose of use, and is easy to install and remove. [Means for solving the problem]

[0010] The prefabricated shed with a wind-resistant structure according to the present invention has a prefabricated shed that can be placed adjacent to a storage shed 1, and the prefabricated shed is equipped with an outer mesh fence 8, a curtain outer wall 10, and an inner mesh fence (for example, an inner upper mesh fence 11 and an inner lower mesh fence 12), which together form a three-layer outer wall structure that gradually attenuates the wind pressure acting on the outer wall from the outside to the inside.

[0011] In the prefabricated shed equipped with the aforementioned wind-resistant structure, the curtain outer wall 10, positioned between the outer mesh fence 8 and the inner mesh fence, is suspended along a rail 9 provided on the top of the shed so as to be able to move freely and be opened and closed. This allows the user to adjust the opening amount as needed. The curtain outer wall 10 may also be structured to be locked to a locking part (e.g., a hook part) provided on the periphery of the ceiling (e.g., the opening and closing roof 2).

[0012] Preferably, the curtain exterior wall 10 is configured to be replaceable without the use of tools, allowing it to be changed from a breathable mosquito net-like curtain in summer to a heat-retaining vinyl curtain in winter. This makes it easy to adjust the thermal environment inside the shed according to the season and usage environment.

[0013] The outer mesh fence 8 is preferably constructed in such a way that it can be attached and detached without the use of tools by fastening fittings provided at its upper and lower ends. This allows for easy removal of the outer mesh fence 8 to enhance safety in the event of strong winds, typhoons, etc. Similarly, the inner mesh fence can also be constructed in such a way that it can be attached and detached without the use of tools.

[0014] In the storage shed, the inner mesh fence is divided into an upper mesh fence 11 and a lower mesh fence 12. The curtain outer wall 10 is configured to be openable and closable by moving the handle 14 of the curtain outer wall 10 in the space formed between the upper mesh fence 11 and the lower mesh fence 12. This allows for smooth opening and closing operations without interfering with the mesh fence while maintaining the three-layer outer wall structure.

[0015] The outer mesh fence 8 is not limited to being secured to the edge of the opening and closing roof 2, but may also be secured to a locking fitting provided on the outside of the roof support column 5.

[0016] The curtain exterior wall 10 is provided with a venting flap 19. The venting flap 19 is composed of multiple venting slits 20 formed at predetermined intervals, for example, in sections of approximately 30 cm x 30 cm. The edges of the flap 19 and slits 20 are preferably reinforced with reinforcing stitching or reinforcing material. Furthermore, it is preferable to provide a weight 21 on the lower edge of the venting flap 19. This allows the flap 19 to open due to wind pressure during strong winds, releasing the wind and suppressing the concentration of wind pressure, while the weight of the weight 21 makes it easier for the flap 19 to return to its closed position when the wind weakens. In addition, the flap 19 can be rolled up and temporarily secured with hook-and-loop fasteners or strings to be used as a small window.

[0017] The roof support columns 5 and fence columns 6 of the prefabricated shed are preferably erected by being inserted into conduit pipes 7 embedded in the concrete slab 4. Furthermore, in order to improve wind resistance in strong winds, the conduit pipes 7 and the roof support columns 5, or the roof support columns 5 and the roof-side mounting brackets provided on the opening / closing roof 2 side, may be fixed by inserting pins or fastening with bolts and nuts.

[0018] The retractable roof 2 preferably includes lightweight sheet material such as a honeycomb core panel. The lightweight sheet material may include, for example, hollow panels or sandwich panels made of resin or metal. Furthermore, when the retractable roof 2 is not used as a roofing material, it may be folded and stored along the outer wall of the storage shed body 1, and may function as insulation for the outer wall of the storage shed body 1. [Effects of the Invention]

[0019] According to the present invention, by adopting a three-layer exterior wall structure consisting of an outer mesh fence 8, a curtain exterior wall 10, and an inner mesh fence, the wind pressure acting on the exterior wall can be gradually dispersed and attenuated from the outside to the inside. As a result, even in strong wind environments such as farmland, the risk of collapse of the prefabricated shed, excessive shaking, and scattering of components can be reduced, improving the overall safety and stability of the shed.

[0020] Furthermore, the curtain outer wall 10 is suspended to move freely along a curtain rail 9 installed at the top of the shed, and the inner mesh fence is divided into upper and lower sections. This allows the user to grasp the handle 14 of the curtain outer wall 10 and open and close it smoothly and freely without interfering with the mesh fence. This improves operability for entry and exit, ventilation, etc.

[0021] Furthermore, by making the curtain exterior wall 10 replaceable without the use of tools—a mosquito net-like curtain with good ventilation in the summer and a vinyl curtain with good heat retention in the winter—a comfortable workspace or rest area can be easily created according to the season and environment. This contributes to improving the work efficiency and comfort of agricultural workers.

[0022] Furthermore, a cut (flap) for ventilation is formed in the curtain outer wall 10, the peripheral edge of the ventilation flap 19 is reinforced by sewing or a reinforcing material, and a weight 21 for the flap is provided at the lower part of the flap. By adopting such a configuration, the ventilation flap 19 opens during strong winds to release the wind, and the wind pressure acting on the outer wall can be reduced. Also, when the wind weakens, the ventilation flap 19 quickly restores and closes due to its own weight and the weight 21 of the flap, so the shielding property and the function of hiding the view during normal times can be maintained, and both the safety during strong winds and the outer wall function during normal times can be achieved.

[0023] Furthermore, by configuring the columns of the prefabricated shed and the fence posts to be inserted into and erected in the sheath pipes 7 embedded in the dirt floor concrete 4, it becomes possible to easily assemble them only by inserting and removing the columns during installation, and the installation and removal are also easy. Also, during strong winds or the like, by making it possible to fix the sheath pipe 7 and the column, or the column and the roof side mounting fitting (on the side of the opening and closing roof 2), by inserting a pin or fastening with bolts and nuts, it is possible to further improve the wind resistance and structural stability while maintaining the simple assembly property.

[0024] As described above, according to the present invention, by combining the three-layer outer wall structure, the flap structure, and the column fixing structure, it is possible to achieve both the safety suitable for a strong wind environment and the constructability and operability as a prefabricated shed, and greatly improve the practicality of the simple shed in the farmland.

[Modes for carrying out the invention]

[0026] Hereinafter, embodiments of the storage shed according to the present invention will be described with reference to the drawings. Note that the embodiments shown below are examples for specifically illustrating the present invention, and the present invention is not limited to these embodiments.

[0027] The storage shed according to this embodiment comprises a storage shed body 1 installed on farmland or the like, and a prefabricated shed installed adjacent to the side of the storage shed body 1. The storage shed body 1 is a general structure made of materials such as steel plates, steel, or wood, and has a storage space inside in which agricultural machinery, fertilizers, agricultural materials, etc. can be stored.

[0028] The aforementioned prefabricated shed is equipped with multiple columns and a retractable roof 2, and forms a three-layer exterior wall structure with an outer mesh fence 8, a curtain exterior wall 10, and inner mesh fences 11 and 12 arranged from the outside to the inside.

[0029] The retractable roof 2 is rotatably locked to the upper end of the side wall of the shed body 1 and is deployed as shown in Figure 1 when in use. Furthermore, after deployment, the roof support columns 5 are inserted into the conduit pipes 7 embedded in the concrete slab 4 as shown in Figure 2 and erected, and the roof support columns 5 and the retractable roof 2 are engaged with a latch-type or insert-type fixing structure as shown in Figure 3, thereby forming the roof of the shed without the use of tools. In addition, in strong winds, the fixing strength of the roof structure can be increased by fastening the connection between the conduit pipes 7 and the roof support columns 5, and between the roof support columns 5 and the retractable roof 2, with bolts and nuts.

[0030] Figure 4 shows the state in which the retractable roof 2 is supported by the roof support columns 5 and the retractable roof 2 is deployed and installed in the predetermined position.

[0031] Thus, with the conduit system, the prefabricated shed can be easily installed and removed simply by inserting and removing the roof support posts 5 and fence posts 6 into and out of the conduit pipes 7.

[0032] As shown in Figure 5, the prefabricated shed of this embodiment forms a three-layer exterior wall structure in which an outer mesh fence 8, a curtain exterior wall 10, and inner mesh fences 11 and 12 are arranged sequentially from the outside to the inside.

[0033] As shown in Figures 5 and 6, the outer mesh fence 8 is secured to the outside of the roof support column 5 via locking fittings provided on the periphery of the opening and closing roof 2, and functions as a sway stopper to suppress the swinging of the curtain outer wall 10. The outer mesh fence 8 is configured to be attachable and detachable without the use of tools by means of the locking fittings. Furthermore, in order to improve wind resistance in strong winds, the lower end of the roof support column 5 and the sheath pipe 7 into which the roof support column 5 is inserted may be configured to be fastened and secured by inserting bolts through pre-formed through holes and fastening them with nuts.

[0034] The outer mesh fence 8 is constructed as a full-coverage fence that extends from the foundation 4 to the periphery of the opening / closing roof 2 (near the roof panels).

[0035] The inner mesh fence is divided into an inner upper mesh fence 11 and an inner lower mesh fence 12, and a movable area is formed between them for gripping and moving the handle 14 of the curtain outer wall 10.

[0036] A curtain rail 9 for suspending the curtain outer wall 10 is provided circumferentially near the inner lower surface of the retractable roof 2. The curtain outer wall 10 is supported so as to be able to move freely via runners attached to the curtain rail 9 and is configured to be able to open and close along the circumferential direction.

[0037] As shown in Figure 6, a curtain rail 9 is pre-installed on the retractable roof 2, and the curtain outer wall 10 is suspended via curtain runners. Alternatively, instead of using the curtain rail 9, the curtain outer wall 10 may be directly suspended by a locking part (hook, etc.) provided on the retractable roof 2 side.

[0038] As shown in Figure 7, a locking fitting (inner upper mesh fence hook) 18 for supporting the inner upper mesh fence 11 is provided on the inside of the curtain rail 9. The inner upper mesh fence 11 is installed by hooking it onto the locking fitting 18. Since the inner upper mesh fence 11 is positioned at the upper part of the ceiling, it is less susceptible to swaying due to wind, and the required holding force can be obtained by hooking it with the locking fitting 18 alone. If necessary, fixing means such as clips, pins, or bolts may be used in combination to increase the mounting strength.

[0039] As shown in Figure 8, the inner lower mesh fence 12 is constructed by inserting fence posts 13 into conduit pipes 7 that are pre-embedded in the concrete slab 4. Furthermore, in order to improve wind resistance during strong winds, it is preferable that through holes are pre-formed in the fence posts 13 and the conduit pipes 7, and that bolts and nuts are inserted through these through holes to fasten and secure them. This prevents the posts 13 from coming loose or rotating during strong winds.

[0040] As shown in Figure 11, by dividing the inner mesh fence into an inner upper mesh fence 11 and an inner lower mesh fence 12, an operating space is formed between them that allows the handle 14 of the curtain outer wall 10 to be operated. This allows the user to smoothly open and close the curtain outer wall 10 without interfering with the inner mesh fence, while maintaining the three-layer outer wall structure (outer mesh fence 8, curtain outer wall 10, inner mesh fences 11 and 12).

[0041] The curtain exterior wall 10 is designed to be replaceable according to the season. In summer, a mosquito net-like curtain can be used to ensure ventilation and insect protection. In winter, a vinyl curtain can be used to improve wind protection and heat retention, creating a simple greenhouse-like environment inside the shed. These can be replaced without tools, as they are engaged with the curtain rail 9.

[0042] These curtains are designed to be easily attached and detached by hand from the runners, allowing for quick and easy replacement without the need for tools.

[0043] As shown in Figure 9, the curtain outer wall 10 is provided with ventilation flaps 19. For example, multiple flaps 19 measuring approximately 30 cm x 30 cm and the periphery of the slit 20 are reinforced with reinforcing stitching or reinforcing material and are provided at predetermined intervals, to which ventilation flaps 19 are attached.

[0044] A flap weight 21 is provided at the bottom of the venting flap 19, and in strong winds, the flap 19 opens due to wind pressure, allowing the wind to escape. As shown in Figure 10, the flap 19 can swing in either direction, inward or outward, of the curtain outer wall 10, and when the wind weakens, the flap 19 automatically returns to its original position due to its own weight and the action of the flap weight 21. This reduces the wind pressure acting on the entire outer wall. In addition, the venting flap 19 can be rolled up and temporarily secured with hook-and-loop fasteners or strings, allowing it to be used as a small ventilation window.

[0045] For the outer mesh fence 8, for example, commercially available mesh panels with a density of about 0.21 can be used, ensuring ventilation with a high opening ratio while effectively attenuating wind pressure acting on the outer wall.

[0046] Furthermore, the three-layer structure consisting of an outer mesh fence 8, a curtain outer wall 10, and inner mesh fences 11 and 12 allows wind to be gradually scattered and attenuated from the outside to the inside, thereby reducing the actual wind pressure acting on the entire prefabricated shed compared to a single fabric wall structure.

[0047] The retractable roof 2 is preferably constructed including lightweight sheet materials such as honeycomb core panels. This makes it possible to reduce the overall weight of the roof while ensuring sufficient bending rigidity and wind resistance.

[0048] The retractable roof 2 can be positioned and stored along the outer perimeter of the storage shed body 1 when not in use, and can also function as insulation for the outer wall of the storage shed body 1.

[0049] When in use, the pillars are inserted into the "sheath pipes" 7 to erect the structure, and after extending the retractable roof 2, the outer mesh fence 8, inner mesh fences 11 and 12, and seasonal curtains 10 are installed in order. The outer curtain wall can be attached to the retractable roof 2 using hooks instead of curtain rails.

[0050] During periods of non-use or when strong winds or typhoons are expected, the outer mesh fence 8, curtain outer wall 10, and inner mesh fences 11 and 12 can be removed, and the retractable roof 2 can be stored in the shed body 1, allowing for easy dismantling and storage of the shed structure.

[0051] The present invention is not limited to the embodiments described above, and those skilled in the art can appropriately modify the materials, dimensions, shape, etc., within the scope of the technical concept described in the claims. [Explanation of symbols]
