Description

Warehouse building and method for manufacturing the same

[0001] The present invention relates to a warehouse building and a method for manufacturing the same.

[0002] Typically, various food products, such as fruits, vegetables, meat, and seafood, are stored in cold storage facilities equipped with refrigeration or freezing facilities to maintain freshness throughout distribution. These cold storage facilities require insulation on the floors and walls, as the interior temperature must be maintained below a certain level (e.g., below 15°C).

[0003] Traditionally, insulation structures for cold storage warehouses were constructed by spraying urethane foam on-site. This spray-on method, however, resulted in low compressive strength, making them prone to damage or collapse under the weight of the numerous items placed inside the warehouse and the rack structures they were loaded with. This, in turn, led to cracking and floor collapse in the finishing materials (e.g., unreinforced concrete) placed on top of the insulation structures.

[0004] An object of the embodiments of the present disclosure is to solve at least some of the problems of the prior art, and to provide a warehouse building having an insulation layer having greater resistance to loads applied by rack assemblies and cargo disposed inside the warehouse building.

[0005] Additionally, it is an object of the embodiments of the present disclosure to provide a warehouse building having an insulation layer that can ensure ease of construction, shortened construction time, and consistency in quality.

[0006] The technical problems of the present disclosure are not limited to the technical problems mentioned above, and other technical problems not mentioned will be clearly understood by those skilled in the art from the description below.

[0007] In order to achieve the above object, in embodiments, a warehouse building is provided, including a base including a base support layer and an insulation layer disposed on an upper side of the base support layer; and a rack assembly disposed on an upper side of the base and configured to allow cargo to be loaded, wherein the rack assembly includes a post frame installed on the base; and a deck frame connected to the post frame and on which cargo is loaded, wherein the insulation layer of the base includes a first insulation part disposed on a lower side of the post frame; and a second insulation part wrapping a side of the first insulation part, wherein the compressive strength of the first insulation part is higher than the compressive strength of the second insulation part.

[0008] In embodiments, the insulation layer may include a plate-shaped insulation board that is fixed to the sub-base and forms a first insulation portion; and a foam insulation material that wraps around the side of the insulation board and forms a second insulation portion.

[0009] In embodiments, the insulation board may be a high-strength urethane board, and the foam insulation may be a urethane foam that is applied to the upper surface of the base support layer and then cured.

[0011] In embodiments, a bonding member may further be included to secure the first insulation to the base support layer.

[0012] In embodiments, the bonding member may include a bonding body portion inserted into the base support layer through the first insulation portion; and a bonding flange portion disposed at an end of the bonding body portion and seated on an upper surface of the first insulation portion.

[0013] In embodiments, a hollow portion open to the upper side is formed in the center of the joint body portion, and the hollow portion can be filled with urethane foam.

[0014] In embodiments, the base further comprises a flat layer comprising concrete covering the insulation layer, and the post frame can be supported on the flat layer.

[0015] In embodiments, the base further includes a reinforcing member disposed between the first insulation member and the post frame to distribute the load applied by the post frame, and the flat layer can be formed to surround the reinforcing member.

[0016] In embodiments, the reinforcing member may have a reinforcing bar mesh structure formed by intersecting multiple reinforcing bars.

[0017] In embodiments, the warehouse building further includes a plurality of warehouse columns that impart structural rigidity to the warehouse building in the height direction, and the post frame can be disposed between the plurality of warehouse columns.

[0018] In embodiments, a method for manufacturing a warehouse building having a rack assembly installed, the method comprising: a foundation construction step of forming a foundation support layer; an insulation construction step of forming an insulation layer on an upper side of the foundation support layer; a leveling step of forming a leveling layer on an upper side of the insulation layer; and a rack installation step of installing a post frame on an upper side of the leveling layer, wherein the insulation construction step includes a first insulation construction step of forming a first insulation part in a first area of ​​an upper surface of the foundation support layer where a post frame is installed; and a second insulation construction step of forming a second insulation part in a second area of ​​an upper surface of the foundation support layer, the remaining area excluding the first area, wherein a compressive strength of the first insulation part is higher than a compressive strength of the second insulation part.

[0019] In the embodiments, in the first insulation construction step, a plate-shaped insulation board may be installed on the upper surface of the foundation support layer to form a first insulation section, and in the second insulation construction step, a foam-type insulation material may be applied to a second area and then cured to form a second insulation section.

[0020] In embodiments, the side of the insulation board is configured to be inclined to form an acute angle with respect to the lower surface of the insulation board, and in the second insulation construction step, a foam type insulation material can be applied to cover the entire side of the insulation board.

[0037] Hereinafter, a warehouse building (10) according to embodiments will be described with reference to the attached drawings.

[0038] FIG. 1 is an exemplary perspective view of a warehouse building (10) according to one embodiment.

[0039] FIG. 2 is an exemplary perspective view of the interior of a warehouse building (10) according to one embodiment.

[0040] Referring to FIGS. 1 and 2, a warehouse building (10) may include a base (100) forming the floor of the warehouse building (10), a warehouse pillar (200) positioned on the upper side of the base (100) to provide structural rigidity in the height direction (e.g., Z-axis direction) to the warehouse building (10), and an outer wall (300) connected to the base (100) and enclosing an internal space (loading space) of the warehouse.

[0041] In embodiments, the warehouse building (10) may be a low-temperature warehouse capable of storing cargo (P) in a frozen or refrigerated state. In this case, to enhance the insulation effect of the warehouse building (10), an insulation layer made of an insulation material with very low thermal conductivity may be arranged on the base portion (100) and the outer wall portion (300). For example, the base portion (100) and the outer wall portion (300) of the warehouse building (10) may be formed by laminating a concrete support layer with high structural rigidity and an insulation layer made of an insulation material with excellent insulation performance.

[0042] The insulating material forming the insulation layer of the warehouse building (10) may be urethane, expanded polystyrene, glass fiber, etc. However, the insulating material forming the insulation layer of the warehouse building (10) is not limited to the above-described materials, and various building insulating materials including thermosetting resins with excellent heat resistance and durability may be combined and applied.

[0043] In order to utilize the loading space of a warehouse building (10) more efficiently, a rack assembly (400) may be installed inside the warehouse building (10). For example, referring to FIG. 2, the rack assembly (400) may be installed on the upper part of the base (100) of the warehouse building (10) and may be structured to be capable of loading a plurality of cargoes (P).

[0044] In embodiments, the rack assembly (400) may be a so-called mezzanine rack, which divides a single floor of a warehouse building (10) into multiple tiers and is configured to allow each tier to be utilized individually. In such a mezzanine rack, each tier can be utilized as a loading space for loading a plurality of cargo (P) and cargo pallets, or as a user work space. Accordingly, the upper and lower spaces of the warehouse building (10) can be utilized as effectively as possible, thereby increasing space utilization and volume ratio.

[0045] Referring to FIG. 2, the rack assembly (400) may include a plurality of deck frames (420) forming each stage on which cargo (P) can be loaded, and a plurality of post frames (410) installed on the base (100) of the warehouse building (10) and supporting the deck frames (420).

[0046] The post frame (410) may be a steel structure extending in the height direction of the warehouse building (10) from the base (100). However, the material of the post frame (410) is not limited to that described above, and may be made of any material that has sufficient rigidity to withstand the load of a plurality of cargoes (P).

[0047] The deck frame (420) is connected to the post frame (410) and may be configured to allow a plurality of cargoes (P) to be loaded. The deck frame (420) may be a steel flat plate structure extending in a direction parallel to the base (100). However, the material of the deck frame (420) is not limited to that described above, and may be made of any material that has sufficient rigidity to withstand the load of a plurality of cargoes (P).

[0048] The load of the cargo (P) loaded on the rack assembly (400) is transferred to the base (100) through the post frame (410). As a large number of cargoes (P) are loaded on the rack assembly (400), a very high load may be concentrated on a local area of ​​the base (100) where the post frame (410) is installed. In order to prevent cracks or sagging in the insulation layer of the base (100) of the warehouse building (10) due to such concentrated load, the warehouse building (10) according to the embodiments may include an insulation layer with reinforced compressive strength in a portion corresponding to the position where the post frame (410) is installed.

[0049] Hereinafter, the insulation layer of the warehouse building (10) according to the embodiments will be described in more detail with reference to FIGS. 3 to 7.

[0050] FIG. 3 is an exemplary cross-sectional view of the interior of a warehouse building (10) according to one embodiment.

[0051] Figure 4 is an enlarged view of part A of Figure 3.

[0052] FIG. 5 is a plan view showing a portion of a base (100) of a warehouse building (10) according to one embodiment.

[0053] Figure 6 is an exemplary perspective view of a first insulation portion (121) forming part of an insulation layer (120).

[0054] Figure 7 is a reference drawing for explaining a reinforcing member installed at the bottom of a post frame (410).

[0055] The warehouse building (10) described in FIGS. 3 to 7 corresponds to the warehouse building (10) described in FIGS. 1 and 2, so any duplicate description may be omitted.

[0056] In embodiments, the rack assembly (400) may be installed on the base (100) of the warehouse building (10). For example, referring to FIG. 3, a plurality of warehouse pillars (200) are installed on the base (100) of the warehouse building (10), and the post frames (410) of the rack assembly (400) may be installed parallel to the warehouse pillars (200). One or more post frames (410) may be installed between two neighboring warehouse pillars (200). However, the specific arrangement position of the post frames (410) is not limited thereto, and may be installed at various positions on the base (100) that do not interfere with the warehouse pillars (200) according to the needs of the user.

[0057] In embodiments, the base (100) may be formed by stacking a base support layer (110), an insulation layer (120), and a flat layer (130). For example, referring to FIG. 4, an insulation layer (120) made of an insulation material may be placed on top of the base support layer (110), and a flat layer (130) forming the floor surface of the warehouse building (10) may be placed on top of the insulation layer (120). However, the structure of the base (100) is not limited to that shown in the drawing, and some layers may be omitted or other layers may be added as needed. For example, in order to secure higher insulation properties, an insulation reinforcement layer (not shown) may be additionally placed on the lower portion of the base support layer (110) of the base (100). In this case, the insulation reinforcement layer (not shown) may be formed of the same material as the insulation layer (120) placed on top of the base support layer (110). Alternatively, each layer of the base (100) may have a structure in which it is divided into sub-layers with different materials or functions.

[0058] The foundation support layer (110) may correspond to a foundation base poured on the upper side of the ground on which the warehouse building (10) is constructed. The foundation support layer (110) may be made of a reinforced concrete structure manufactured using a PC (Precast Concrete) or RC (Reinforced Concrete) method, but the material and construction method are not limited thereto.

[0059] An insulating layer (120) may be formed on the upper side of the foundation support layer (110). The insulating layer (120) may serve to block heat exchange between the inside and outside of the warehouse building (10). To this end, the insulating layer (120) may be formed of an insulating material with low thermal conductivity.

[0060] The flat layer (130) is placed on top of the foundation support layer (110) and the insulation layer (120) and forms a flat floor surface of the warehouse building (10). The flat layer (130) may have a plain concrete structure that is not reinforced with steel or steel fiber or has a minimal reinforcing ratio.

[0061] In embodiments, the insulation layer (120) of the base (100) may have a reinforced structure so as to more effectively withstand the load of the rack assembly (400) and the loaded cargo. For example, a portion of the insulation layer (120) of the base (100) corresponding to an area where the load is concentrated by the rack assembly (400) may be configured to have a relatively higher compressive strength than other portions of the insulation layer (120). Here, the 'compressive strength' may mean the maximum compressive stress that a material can withstand without being destroyed.

[0062] Referring to FIG. 4, the insulation layer (120) of the base (100) may include a first insulation portion (121) having a relatively high compressive strength and a second insulation portion (122) having a lower compressive strength than the first insulation portion (121).

[0063] The first insulation member (121) may be placed at a location where a high load is applied by the rack assembly (400). For example, as illustrated in FIG. 4, the first insulation member (121) may be placed vertically below the post frame (410) of the rack assembly (400).

[0064] The second insulation part (122) may be formed in the remaining area of ​​the insulation layer (120) except for the area where the first insulation part (121) is disposed. For example, referring to FIGS. 4 and 5 together, the first insulation part (121) may be disposed in the first area (S1), which is the area corresponding to the portion of the insulation layer (120) where the post frame (410) is installed, and the second insulation part (122) may be disposed in the second area (S2), which is the remaining area excluding the first area (S1). The second insulation part (122) is configured to completely surround the side surface (121a) of the first insulation part (121) along the edge of the first insulation part (121), so that a continuous insulation layer (120) in which the first insulation part (121) and the second insulation part (122) are connected to each other may be formed.

[0065] The warehouse building (10) according to the embodiments can effectively increase the structural rigidity of the insulation layer (120) by arranging a first insulation part (121) having a relatively high compressive strength in a local area where a high load is applied through a post frame (410) in the base part (100).

[0066] In the embodiments, the first insulation portion (121) may be formed of a plate-shaped insulation board, and the second insulation portion (122) may be formed of a foam insulation material applied around the insulation board. In this case, the insulation board is configured to have a higher compressive strength than the foam insulation material, and may be manufactured in advance at a location other than the construction site of the warehouse building (10), and the foam insulation material may be manufactured by a construction worker's spraying process at the construction site of the warehouse building (10).

[0067] For example, the insulation board forming the first insulation section (121) may be a high-strength urethane board, and the foam insulation forming the second insulation section (122) may be a urethane foam that is applied to the upper side of the base support layer (110) and then cured. In this case, the compressive strength of the high-strength urethane board forming the first insulation section (121) may be 40 N / cm. 2and the thermal conductivity may be 0.019 W / (m·K) or less. However, the compressive strength and thermal conductivity of the high-strength urethane board forming the first insulation portion (121) are not limited to the above-described values, and may be appropriately changed in response to the insulation performance and structural rigidity required for the insulation layer (120) of the warehouse building (10).

[0068] Unlike foam insulation that is sprayed and installed at the installation site of the warehouse building (10), the insulation board can be manufactured in advance at a location other than the installation site of the warehouse building (10), so that it can be transported to the construction site of the warehouse building (10) in a finished product state and installed immediately, thereby shortening the overall air of the warehouse building (10).

[0069] In addition, in the case of foam insulation, it may be difficult to maintain quality consistency due to the skill of the on-site construction worker performing the spraying work or the surrounding environment of the construction site, but since insulation boards can be manufactured in advance at a consistent quality in the factory, it is more advantageous to maintain quality consistency of the first insulation part.

[0070] In particular, in the case of foam insulation materials that are spray-applied, since the presence of defects or flaws can be confirmed after the insulation layer (120) is completed, repair or re-construction is difficult, and there was a concern that the entire construction period would be delayed due to re-construction. However, in the case of insulation boards supplied in a finished product state, the presence or absence of product defects can be confirmed in advance before the insulation layer (120) is constructed, so construction efficiency can be increased.

[0071] However, high-quality insulation boards with high compressive strength may be relatively more expensive to manufacture than foam insulation manufactured by spraying. Therefore, the warehouse assembly according to the embodiments applies insulation boards with high compressive strength locally only to the portion where the load of the rack assembly (400) and the loaded cargo is concentrated {for example, the first region (S1) of FIG. 5}, and applies foam insulation to the remaining portion {for example, the second region (S2) of FIG. 5}, thereby implementing an insulation layer (120) that maximizes ease of construction, structural rigidity, and insulation while minimizing cost increase.

[0072] However, unlike the above, the insulation layer (120) of the warehouse building (10) according to the embodiments may be entirely composed of insulation boards. For example, the insulation layer (120) may be formed by arranging a plurality of insulation boards side by side on the upper surface of the foundation support layer (110). If necessary, it is also possible to form the first insulation part (121) with a first insulation board having a relatively high compressive strength, and to form the second insulation part (122) with a second insulation board having a lower compressive strength than the first insulation board.

[0073] Since the insulation layer (120) includes two distinct components, i.e., a first insulation portion (121) and a second insulation portion (122), it is necessary to prevent the occurrence of a heat bridge phenomenon in which heat leaks through the gap between the first insulation portion (121) and the second insulation portion (122).

[0074] To this end, in embodiments, the side surface (121a) of the first insulating portion (121) may be provided with an inclined structure. For example, referring to FIG. 4, the side surface (121a) of the insulating board forming the first insulating portion (121) may be configured as an inclined surface that is inclined to form an acute angle with respect to the lower surface (121b) of the insulating board. In this case, the angle between the side surface (121a) of the insulating board and the lower surface (121b) of the insulating board may be approximately 30 to 45 degrees, but the specific value is not limited thereto.

[0075] The second insulation portion (122) can surround and cover the side surface (121a) of the first insulation portion (121). Accordingly, the side surface (121a) of the first insulation portion (121) can overlap the second insulation portion (122) in a direction perpendicular to the lower surface (121b) of the first insulation portion (121) or in the height direction of the warehouse building (e.g., the Z-axis direction). By configuring the side surface (121a) of the first insulation portion (121) as a sloped surface covered by the second insulation portion (122) in this way, the occurrence of a thermal bridge phenomenon along the gap formed at the boundary between the first insulation portion (121) and the second insulation portion (122) can be suppressed as much as possible.

[0076] In addition, as the side surface (121a) of the first insulation part (121) is configured as an inclined surface, the contact area with the second insulation part (122) increases, so that the adhesiveness between the first insulation part (121) and the second insulation part (122) can also be increased.

[0077] Although not shown in the drawing, in order to further increase the contact area between the first insulation portion (121) and the second insulation portion (122), at least a portion of the side surface (121a) of the first insulation portion (121) may include a step structure, a rough structure, or a curved surface.

[0078] Alternatively, unlike that shown in FIG. 4, the side surface (121a) of the first insulating portion (121) may be configured as an inclined surface that forms an obtuse angle with respect to the lower surface (121b) of the first insulating portion (121).

[0079] In embodiments, the insulation layer (120) can be constructed by bonding the first insulation part (121) to the base support layer (110) and then forming the second insulation part (122) around the first insulation part (121).

[0080] For example, referring to FIG. 5, the insulation can be constructed by first aligning the first insulation part (121) in the first area (S1) where the post frame (410) is to be installed, then joining it to the foundation support layer (110), and then forming the second insulation part (122) in the second area (S2) on the upper surface of the foundation support layer (110).

[0081] In embodiments, the warehouse building (10) may further include a connecting member (140) that connects the first insulation member (121) to the foundation support layer (110). For example, referring to FIG. 6, the connecting member (140) may be provided in the form of a bolt, nail, or fastener that penetrates the first insulation member (121) and is inserted into the foundation support layer (110).

[0082] In embodiments, the joining member (140) may include a joining body portion (141) inserted into the base support layer (110) through the first insulation portion (121), and a joining flange portion (142) disposed at an end of the joining body portion (141) and hooked onto the upper surface of the first insulation portion (121).

[0083] When a hollow portion (143) is formed in the joining body portion (141) of the joining member (140), an insulating material may be filled in the hollow portion (143) to prevent a thermal bridge phenomenon from occurring through the joining member (140). For example, after the first insulating portion (121) is firmly fixed to the base support layer (110) through the joining member (140), in the process of forming the second insulating portion (122), a foam insulating material may be filled in the hollow portion (143) of the joining member (140) to fill the hollow portion (143) with the insulating material. Accordingly, the first insulating portion (121) can be stably and tightly joined to the upper surface of the base support layer (110) through the joining member (140), while also preventing a thermal bridge phenomenon from occurring in the joining member (140).

[0084] However, the structure of the bonding member (140) is not limited to that described above, and can be implemented with any structure as long as it can stably fix the first insulation part (121) to the upper side of the base support layer (110). Alternatively, without such a bonding member (140), the first insulation part (121) may be fixed to the upper side of the base support layer (110) using an adhesive material.

[0085] In order for the insulation layer (120) to more effectively withstand the load applied by the rack assembly (400), the warehouse assembly according to the embodiments may further include a reinforcing member (150) disposed on the upper side of the first insulation portion (121) to distribute the load applied by the post frame (410).

[0086] For example, referring to FIGS. 4 and 7 together, the reinforcing member (150) is a structure placed between the post frame (410) and the first insulation member (121), and can be configured so that the load applied by the post frame (410) is evenly distributed over the entire area of ​​the first insulation member (121).

[0087] In embodiments, the reinforcing member (150) may be provided as a reinforcing bar mesh structure formed by intersecting multiple reinforcing bars. This reinforcing bar mesh structure may be configured to cover the upper surface of the first insulation portion (121), thereby allowing the load applied by the post frame (410) to be evenly distributed across the upper surface of the first insulation portion (121).

[0088] The reinforcing member (150) can be placed inside the flattening layer (130). For example, after constructing the reinforcing member (150) on the upper side of the first insulation part (121), concrete can be poured to construct the flattening layer (130). (In FIG. 10, the spacer installed to support the reinforcing member (150) before concrete pouring is omitted from the illustration.) Accordingly, the flattening layer (130) can be formed on the upper side of the insulation layer (120) while wrapping around the reinforcing member (150).

[0089] In this way, the reinforcing member (150) placed inside the flat layer (130) prevents the load of the first insulation part (121) rack assembly (400) from being concentrated on a specific area of ​​the base (100), thereby enabling the flat layer (130) and the insulation layer (120) to more effectively withstand the load of the rack assembly (400).

[0090] Hereinafter, with reference to FIGS. 8 to 12, the construction sequence of the base (100) and rack assembly (400) of the warehouse building (10) according to the embodiments will be described.

[0091] FIGS. 8 to 12 are cross-sectional views illustrating the construction sequence of the base (100) and rack assembly (400) of a warehouse building according to one embodiment.

[0092] The warehouse building described in FIGS. 8 to 12 corresponds to the warehouse building (10) described in FIGS. 1 to 7, so any duplicate description may be omitted.

[0093] In embodiments, the base (100) of the warehouse building (10) may include a foundation construction step of forming a foundation support layer (110), an insulation construction step of forming an insulation layer (120) on the upper side of the foundation support layer (110), a leveling step of forming a leveling layer (130) on the upper side of the insulation layer (120), and a rack installation step of installing the post frame (410) on the upper side of the leveling layer (130).

[0094] In the basic construction stage, the foundation support layer (110) can be formed by leveling the site using construction equipment, etc. at the location where the warehouse building (10) is to be constructed, then pouring concrete to a predetermined thickness and allowing it to cure. However, the material forming the foundation support layer (110) is not limited to concrete, and any material that can be used as the foundation base of the building can be applied without limitation.

[0095] In the insulation construction step, an insulation layer (120) can be constructed on the upper side of the foundation support layer (110). The insulation construction step may include a first insulation construction step of forming a first insulation part (121) in an area where a relatively high compressive strength is required in the insulation layer (120) {for example, the first area (S1) illustrated in FIG. 5}, and a second insulation construction step of forming a second insulation part (122) in an area other than the area where the first insulation part (121) is arranged {for example, the second area (S2) illustrated in FIG. 5}.

[0096] Referring to Fig. 8, in the first insulation construction stage, the first insulation part (121) may be placed on the upper surface of the foundation support layer (110). The position where the first insulation part (121) is placed may correspond to the position where the post frame (410) of the rack assembly (400) is to be installed in the future.

[0097] In the first insulation construction stage, the first insulation part (121) can be joined to the upper surface of the foundation support layer (110) via a joining member (140). For example, the first insulation part (121) can be formed by inserting a fastener-type joining member (140) into the insulation board while the high-strength urethane board is positioned on the upper surface of the foundation support layer (110). If the joining member (140) is used in this way, the first insulation part (121) can be stably and tightly fixed to the upper surface of the foundation support layer (110) even when the flatness of the upper surface of the foundation support layer (110) is not good.

[0098] Referring to Fig. 9, in the second insulation construction stage, a second insulation part (122) is formed in the remaining area excluding the area where the first insulation part (121) is placed.

[0099] The second insulation portion (122) can be formed by manufacturing a foam insulation material through spraying. For example, the second insulation portion (122) can be formed by applying urethane foam to a predetermined height around the first insulation material and then curing it.

[0100] The second insulation part (122) may be formed to wrap around and cover the side surface (121a) of the first insulation part (121). In this case, the side surface (121a) of the first insulation part (121) may be configured to be inclined with respect to the upper surface of the base support layer (110), thereby increasing the contact area between the second insulation part (122) and the first insulation part (121), thereby improving the bonding strength between them. In addition, by forming the side surface (121a) of the first insulation part (121) to be inclined and the second insulation part (122) covering it, the thermal bridge phenomenon can be prevented from occurring in the gap between the first insulation part (121) and the second insulation part (122).

[0101] Meanwhile, during the process of constructing the second insulation part (122), the hollow portion (e.g., 143 in FIG. 6) of the connecting member (140) connected to the first insulation part (121) can also be filled with foam insulation. Accordingly, the thermal bridge phenomenon can be prevented from occurring through the connecting member (140).

[0102] In the leveling stage, a leveling layer (130) can be formed on top of the insulation layer (120). The leveling layer (130) can be formed by pouring concrete and can have a plain concrete structure that is not reinforced with steel or steel fibers or has a minimal reinforcing ratio.

[0103] The leveling step may include a first leveling step of installing a reinforcing member (150) on the upper side of the first insulation member (121) and a second leveling step of forming a leveling layer (130) by pouring concrete.

[0104] For example, referring to Fig. 10, a reinforcing member (150) may be installed on the upper side of the first insulation part (121) in the first flattening step. The reinforcing member (150) may be provided in a reinforcing bar mesh structure formed by intersecting multiple reinforcing bars and may be fixed to the upper side of the first insulation part (121). The reinforcing member (150) may play a role in evenly distributing the load applied by the post frame (410) over the entire area of ​​the first insulation part (121).

[0105] Referring to Fig. 11, in the second leveling step, concrete is poured on top of the insulation layer (120) to form a leveling layer (130) having a flat upper surface. The concrete forming the leveling layer (130) can surround the reinforcing member (150) during the pouring process, and thus the reinforcing member (150) can be firmly fixed to the interior of the leveling layer (130).

[0106] Referring to Fig. 12, in the rack installation step, a post frame (410) of a rack assembly (e.g., 400 of Figs. 2 and 3) may be installed on the upper surface of the flat layer (130). For example, the post frame (410) of the rack assembly (400) may be installed at a position corresponding to the first insulation portion (121) on the upper surface of the flat layer (130), and the rack assembly (400) may be installed by mutually assembling the post frame (410) and the deck frame (e.g., 420 of Figs. 2 and 3). By installing the post frame (410) on the upper side of the first insulation portion (121) having high compressive strength in this way, it is possible to prevent the insulation layer (120) from sinking due to the load of the rack assembly (400) and the loaded cargo.

[0107] In particular, unlike a foundation support layer (110) or a flat layer (130) that can be formed of concrete, etc., an insulation layer (120) including an insulation material is relatively more likely to be deformed or damaged by the load of the rack assembly (400). However, the warehouse building (10) according to the embodiments can significantly increase the load-resisting capacity of the insulation layer (120) by arranging an insulation board having a high compressive strength at the bottom of the post frame (410) where the load of the rack assembly (400) is concentrated.

[0108] In addition, since the insulation layer (120) can better withstand the concentrated load of the rack assembly (400), the number of post frames (410) constituting the rack assembly (400) can be reduced, thereby securing a wider user work space. Accordingly, not only user work efficiency can be increased, but also loading efficiency can be increased.

[0109] While various embodiments of the present invention have been described in detail above, the scope of the present invention is not limited thereto, and it will be apparent to those skilled in the art that various modifications and variations are possible without departing from the technical spirit of the present invention as set forth in the claims. Furthermore, the embodiments described above may be implemented by deleting some components, and the embodiments may be implemented in combination with each other.
