Description

Technology Field

[0001] The present invention relates to a modular building structure that allows multiple modules to be connected vertically or horizontally to assemble it into various functions and forms, such as classrooms or houses. In particular, it relates to a seismic-resistant modular building structure that is easy to assemble and disassemble, which enhances seismic performance, facilitates assembly and disassembly, and allows modules to be added or removed as needed, thereby enabling utilization in various forms and uses. Background Technology

[0002] Generally, as construction technology and building material-related technologies advance, buildings of various functions and forms are being constructed. While these buildings are typically built by laying bricks, erecting a frame and laying bricks between the frames, or forming walls, the recent development of diverse building materials with excellent waterproofing and soundproofing effects has led to the frequent construction of prefabricated buildings that are easy to install and have short construction periods.

[0003] At this time, regarding the technology for architectural structures such as modular houses or warehouses constructed in various forms by connecting multiple modules horizontally or vertically, the following are:

[0004] Korean Patent Registration No. 10-1471039 (registered on December 3, 2014, hereinafter referred to as 'Document 1') "Container-type prefabricated modular house" is disclosed,

[0005] Literature 1 describes a technology for a container prefabricated modular house in which a house is constructed by connecting two or more containers, and not only can a connection wing be formed at the connection part of the two containers to prevent leakage between the two containers, but a guide groove and a guide protrusion are also formed on the connection wing to allow the two containers to be easily aligned when assembled, thereby preventing rainwater from leaking into the connection part between the two containers of a house made by connecting two or more containers.

[0006] As another technology, Korean Patent Registration No. 10-2172044 (registered on October 26, 2020, hereinafter referred to as 'Document 2') “Modular booth using modular construction method and method for manufacturing the same” is presented,

[0007] Document 2 comprises a module assembly formed by assembling multiple architectural modules that provide a space for accommodating medical staff and patients, and having an entrance provided for the entry and exit of said medical staff and said patients; and an anteroom provided within said module assembly to allow entry and exit from said entrance; The technology relates to a modular booth using a modular construction method and a method for manufacturing the same, comprising: an isolation room that is provided to be accessible through the anteroom and has a toilet; wherein doors for access are installed in the anteroom and the isolation room, respectively, and the anteroom and the isolation room are airtightly sealed to enable negative pressure isolation through the supply and exhaust of air, thereby facilitating construction and installation, allowing it to be used as a public facility such as a conference room, public relations room, or lounge in normal times, and enabling rapid conversion into a screening clinic or negative pressure isolation room in emergencies such as the spread of infectious diseases, thereby increasing the utilization of the building structure in normal times and enabling rapid testing or accommodation of patients with infectious diseases such as COVID-19 in emergencies, thereby suppressing the spread of infectious diseases such as COVID-19 and enabling an efficient response to confirmed cases of infectious diseases.

[0008] Another technology is disclosed in Korean Patent Registration No. 10-2447901 (registered September 22, 2022, hereinafter referred to as 'Document 3'), titled "Connection System and Connection Method for Prefabricated Volumetric Building Modules."

[0009] Literature 3 describes a connection system and method for prefabricated volumetric building modules having a connection mechanism for fixing to other similar modules, comprising a self-supporting structure and pairs of corner castings placed at least at the corners of the structure, and during building construction, the modules are assembled and fixed together using connecting rods and interlocking plates to provide vertical fixation between vertical adjacent modules and horizontal fixation between horizontal adjacent modules.

[0010] In this context, Reference 1 states that additional reinforcement may be required to ensure structural stability when stacking containers, Reference 2 states that errors in module joints may lead to quality degradation and require precise design and construction techniques to resolve this, and Reference 3 states that although the modular system can be disassembled and reassembled, structural damage may occur during the repetitive assembly process. Furthermore, References 1 to 3 lack a seismic structure, which poses a problem that safety accidents may occur in the event of a disaster such as an earthquake. Prior art literature

Specific details for implementing the invention

[0025] Preferred embodiments of the present invention will be described in detail below with reference to the attached drawings.

[0026] Prior to this, terms and words used in this specification and claims should not be interpreted as being limited to their ordinary or dictionary meanings, but should be interpreted in a meaning and concept consistent with the technical spirit of the invention, based on the principle that the inventor can appropriately define the concept of the terms to best describe his invention. Accordingly, the embodiments described in this specification and the configurations illustrated in the drawings are merely one preferred embodiment of the invention and do not represent all of the technical spirit of the invention; therefore, it should be understood that various equivalents and modifications capable of replacing them may exist at the time of filing this application.

[0027] Based on Figure 4, the direction is specified as the housing side being lower or downward, and the post side being upper or upward.

[0028] As illustrated in FIGS. 1 to 10, the seismic-resistant modular building structure that is easy to assemble and disassemble according to the present invention is,

[0029] It is largely composed of a building module (10), a connector (20), and a snapping unit (30).

[0030] If we look at each component,

[0031] The above architectural module (10) is

[0032] As illustrated in FIGS. 1 to 3,

[0033] It consists of a rectangular enclosure structure with an internal space for accommodating users.

[0034] Multiple horizontal and vertical frames are interconnected to form a frame, and various types of auxiliary frames are connected between the frames of this frame to design and manufacture door frames for doors, window frames for windows, spaces for system air conditioners, spaces for floor boiler piping, spaces for ceiling wiring, etc.

[0035] Ultimately, the above-mentioned architectural module (10) is based on a square enclosure structure frame and can be modified to have various functions and shapes suitable for use (e.g., classroom, warehouse, house, etc.).

[0036] The above connector (20)

[0037] As illustrated in FIGS. 1 to 3, FIGS. 7 and FIGS. 8,

[0038] It is composed of a cylindrical structure placed in the lower four corner areas of the above-mentioned architectural module (10).

[0039] Although the connector (20) of this structure is placed in the lower four corner areas of the building module (10), depending on the size of the building module (10), a number of additional connectors may be placed in the intermediate area connecting the front and rear corner areas, or a number of additional connectors may be placed in the intermediate area connecting the left and right corner areas.

[0040] The above snapping unit (30) is

[0041] As illustrated in FIGS. 4 to 10,

[0042] A housing (31) positioned in the upper four corner areas of the above-mentioned architectural module (10) and having a rectangular space (311) into which the connector (20) enters, and

[0043] n springs (32, wherein n is an integer greater than or equal to 2) for setting the correct position while pressing and fixing the connector (20) that has entered the housing (31)

[0044] It consists of including

[0045] At this time, as shown in FIGS. 4 to 7, the snapping unit (30) is further provided with four posts (33) that are positioned to be erected in the inner corner area of ​​the space portion (311) in the housing (31) and have circular insert grooves (331) formed on each of their facing surfaces, and four holding pins (34) that are inserted into the insert grooves (331) of each post (33) to interconnect two adjacent posts (33), thereby forming a square when viewed from above.

[0046] And it is preferable that the integer n representing the quantity of the above spring (32) is 4.

[0047] Eventually, as shown in Fig. 7, the spring (32) is inserted in a horizontal position into each of the four holding pins (34), and the connector (20) that has entered the space (311) of the housing (31) is assembled by pushing the four springs (32) and elastically deforming them.

[0048] At this time, as shown in FIG. 8, a tread portion (21) is formed at the end of the connector (20), which is recessed along the outer surface and forms a U-shape when viewed from the side, and is supported by the undeformed spring (32).

[0049] The term 'non-deformation' above means a state in which the spring (32) is elastically deformed by the connector (20) and then restored to its original shape upon contact with the tread portion (21).

[0050] Accordingly, when the connector (20) enters the space (311) of the housing (31) while the spring (32) is inserted in a horizontal position on the four holding pins (34), elastic deformation occurs, and in this process, the spring (32) effectively supports the connector (20) and exerts a strong holding force, thereby preventing the connector (20) from shaking or falling off.

[0051] Furthermore, by utilizing the elastic deformation characteristics of the spring (32), it serves to absorb external shocks or vibrations. In other words, it provides stability so that the connector (20) does not shake or move in the external environment, thereby improving the overall durability of the modular building structure.

[0052] In addition, since the spring (32) is inserted into the holding pin (34) while lying down, a snapping process is performed in which the connector (20) is naturally pushed in and engaged when entering the space (311), and during this process, the spring (32) is deformed, making assembly easier and reducing damage to parts during repeated assembly and disassembly processes.

[0053] In addition, since a tread portion (21) supported by an undeformed spring (32) is formed at the end of the connector (20), the connector (20) can be pressed and fixed in an accurate position through a structure that is recessed along the outer surface.

[0054] Meanwhile, as shown in FIG. 8, a guide (22) is formed at the end of the connector (20) to guide initial entry when entering the space (311) of the housing (31).

[0055] At this time, the guide (22) helps the connector (20) to be aligned in the correct direction during the initial insertion stage, thereby preventing unnecessary friction or force from being applied, which can improve the stability of the assembly process.

[0056] Furthermore, the guide (22) provides a natural guiding effect when the connector (20) is inserted into the space (311) of the housing (31), thereby minimizing damage and increasing durability during repeated connection and disconnection.

[0057] In addition, since the guide (22) guides the correct path during initial entry, the connector (20) can be accurately positioned at the desired location, allowing for stable assembly.

[0058] Meanwhile, as shown in FIG. 7, the spring (32) fitted into the holding pin (34) has a width (W) that is smaller than the length (L) of the holding pin (34) exposed to the outside, so a gap (S) is formed between the two adjacent posts (33) and the spring (32) fitted into the holding pin (34).

[0059] At this time, since the width (W) of the spring (32) is smaller than the length (L) of the holding pin (34), a clearance space (S) is formed between it and the adjacent post (33), and the spring (32) can undergo elastic deformation without interference when the connector (20) enters.

[0060] Furthermore, the above-mentioned gap (S) allows the spring (32) to move freely and absorb vibrations when an external shock is applied, thereby reducing the accumulation of fatigue in the spring (32).

[0061] In addition, since the spring (32) is mounted while maintaining an appropriate distance from the holding pin (34), replacement of parts during maintenance becomes easy, and precise position adjustment is possible.

[0062] In addition, when the part expands or contracts due to temperature changes, the gap (S) acts as a buffer to minimize structural deformation, thereby ensuring long-term stability for the snapping unit (30).

[0063] Meanwhile, as shown in FIG. 9, the snapping unit (30) is further provided with a stopper (35) that supports the area in contact with the inner wall of the space portion (311) of the housing (31) from the spring (32) by being formed to protrude from each face facing each post (33) and placed in the spaced space (S).

[0064] At this time, the stopper (35) placed in the gap space (S) controls the movement of the spring (32) to prevent unnecessary deformation or displacement. In other words, the stopper (35) supports the opposite area, that is, the area in contact with the inner wall of the space (311) of the housing (31), rather than the adjacent area where the connector (20) is elastically deformed when the spring (32) enters. This allows the elastic deformation of the spring (32) to continue while the opposite area is stably supported, thereby enabling the spring (32) to elastically deform without movement along the length direction of the holding pin (34) and support the connector (20).

[0065] Furthermore, the stopper (35) helps the spring (32) to be accurately positioned at the intended location, and the connection of the connector (20) can be made more secure.

[0066] Meanwhile, as shown in FIG. 10, the snapping unit (30) is further provided with four supports (36) that are positioned in the upper inner corner area of ​​the space (311) of the housing (31) and support the upper end of each post (33).

[0067] At this time, each of the above supports (36) may be formed individually and joined to the top of the housing (31) by means of bolting, etc., or each of the above supports (36) may be formed integrally within a hollow square plate and joined to the top of the housing (31) by means of bolting, etc.

[0068] Therefore, the support (36) supports the top of the post (33), thereby increasing the rigidity of the overall structure, and through this, the connector (20) and the housing (31) can be stably combined without deformation or shaking during assembly.

[0069] Furthermore, by placing the support (36) in the inner corner area of ​​the space (311) of the housing (31), internal stress is distributed, long-term durability is improved, and deformation or damage can be minimized even when external force is applied.

[0070] In addition, the support (36) acts as a structural buffer between the housing (31) and the post (33), protecting against external vibrations or shocks, thereby maintaining connection stability and preventing performance degradation even with repeated use.

[0071] In addition, as the upper part of the post (33) is supported by the support (36), the assembly position is maintained more precisely, and thereby the connector (20) can be joined at the correct position.

[0072] Ultimately, the additional placement of the above support (36) serves to increase the strength of the overall structure and minimize problems that may occur during assembly and use.

[0073] In describing the present invention above, the focus has been on a "seismic-resistant modular building structure that is easy to assemble and disassemble" having a specific shape and structure with reference to the attached drawings; however, the present invention is capable of various modifications and changes by those skilled in the art, and such modifications and changes should be interpreted as falling within the scope of protection of the present invention.
