Description

Technology Field

[0001] The present invention relates to a temporary soundproof house installed at a construction site, and more specifically, to a soundproof house in which a ventilation opening formed through a fixed roof is opened and closed by sliding a movable roof in a horizontal direction after the movable roof is raised in a vertical direction, and in the closed position, the movable roof is inserted into the ventilation opening to form a flat plane with the surface of the fixed roof, thereby simultaneously securing soundproofing performance and ventilation function. Background Technology

[0002] Noise and dust generated at urban construction sites are the primary cause of environmental complaints that inflict serious damage on nearby residential areas and commercial facilities. To mitigate this, temporary soundproof houses, which enclose the entire construction site with steel frames and soundproof panels, are being introduced at large-scale construction and civil engineering sites. However, due to the structural characteristics of soundproof houses that seal the interior, they inherently suffer from ventilation problems, where exhaust gases from heavy equipment such as excavators and dump trucks, airborne dust, and internal heat accumulate rapidly within the structure. Particularly during the summer, internal temperatures rise sharply, threatening worker safety and the normal operation of equipment; therefore, there is a need for the development of roof opening and closing technology that can effectively circulate internal air without compromising noise-blocking capabilities.

[0003] To meet this demand, technologies have been proposed for opening and closing a portion of the roof using a sliding method.

[0004] Korean Patent No. 10-1636658 (hereinafter referred to as Document 1) discloses a retractable roof for a livestock barn in which a plurality of openings and closing holes are formed in the fixed roof of the livestock barn, and a movable roof connected to a rail via a guide roller slides in the forward and backward directions by means of a rotating means consisting of a rotating rod and a wire to open and close the openings and closing holes. However, the technology of Document 1 was developed for the purpose of lighting and ventilation of the livestock barn and did not consider soundproofing performance at all. Furthermore, since the movable roof is structured to simply slide horizontally on the upper surface of the fixed roof, a step and gap inevitably occur between the movable roof and the openings and closing holes when closed, which has the problem of not being able to satisfy soundproofing and waterproofing functions.

[0005] Korean Registered Patent No. 10-1748343 (hereinafter referred to as Document 2) discloses a movable roof opening and closing device comprising a plurality of rails installed at an angle on the roof of an outdoor facility, a movable platform movably coupled to each rail, a connecting shaft connected in series to the drive shaft of a motor, and a lifting means in which a rope is wound around a bobbin of the connecting shaft to slide the movable platform. Although Document 2 secures the driving stability of the movable platform through a first guide roller that contacts and supports the upper inner surface of the rail and a second guide roller that is symmetrically supported on the inner side of the rail, the winding drive method using a rope and a bobbin is vulnerable to rope sagging and eccentric loads during operation, and since the movable roof has a structure that moves horizontally along the rail on an inclined surface, it has limitations in that it cannot form a plane with the fixed roof in the closed position, making it difficult to satisfy the strict soundproofing and waterproofing performance required for soundproof houses at construction sites.

[0006] Korean Registered Patent No. 10-1423309 (hereinafter referred to as Document 3) discloses an openable roof structure in which an opening is formed at the ridge of the main roof of a gable roof type, and the left and right upper auxiliary roofs are raised upward using a cylinder axis to open the ridge opening, and then rotated by a hinge to regulate the ventilation volume. However, the technology of Document 3 was developed for controlling lighting and ventilation in livestock breeding facilities, and since the auxiliary roof is a structure in which the auxiliary roof rotates open by a hinge over the slope of the main roof, there are limitations in the adhesion performance with the main roof when closed, and it is difficult to apply to large temporary structures for construction sites equipped with soundproof panels.

[0007] Korean Registered Patent No. 10-1344769 (hereinafter referred to as Document 4) discloses a soundproof tunnel-type structure installed along a railway track, wherein a plurality of movable soundproof panel sections open and close a ventilation opening formed in the upper frame of the structure by sliding symmetrically in both directions relative to the center of the ventilation opening, and the structure has an automatic sliding opening / closing soundproof member in which a drive unit consisting of a ball screw and a motor operates electrically. However, since Document 4 is a structure dedicated to soundproofing railway tracks and the movable soundproof panel sections only slide horizontally, the movable roof remains stacked on the upper frame even after sliding movement, which limits the open area and presents the problem that it is difficult to completely seal the gap between the movable panel and the ventilation opening when closed. Furthermore, it is not suitable for applications requiring large openings that allow for the loading and unloading of materials using a crane, such as soundproof houses at construction sites.

[0008] As such, conventional retractable roof technologies were primarily developed for the purposes of lighting and ventilation in livestock barns or temperature management in railway soundproof tunnels; they had the problem of failing to simultaneously satisfy the complex technical requirements demanded by soundproof houses at construction sites, such as the compatibility of noise blocking performance and ventilation functions, the formation of a completely flat plane between the movable and fixed roofs when closed, and the securing of waterproofing and airtightness performance through compression sealing.

[0014] Reference 5: Republic of Korea Registered Design No. 30-1137973 (Date of Announcement: Nov. 22, 2021) The problem to be solved

[0015] The present invention has been devised to solve the problems of the aforementioned prior art and aims to provide a soundproof house that can simultaneously secure soundproofing performance and waterproof airtightness performance. In this soundproof house installed at a construction site, a ventilation opening formed in a fixed roof is opened and closed by the movable roof sequentially performing a vertical lifting movement and a horizontal sliding movement. In the closed position, the movable roof is inserted into the interior of the ventilation opening, forms a plane flush with the surface of the fixed roof, and is pressed and adhered to the inner circumference of the ventilation opening through a sealing member.

[0016] In addition, another objective of the present invention is to provide a soundproof house capable of precisely controlling the movement position of the movable roof by adopting a rack and pinion meshing method as a sliding driving means for the movable roof, thereby eliminating rope sagging, twisting due to eccentric load, and driving noise that occurred in conventional rope and bobbin winding methods.

[0017] In addition, another objective of the present invention is to provide a soundproof house that can rapidly discharge exhaust gases and heat from heavy equipment and simultaneously be utilized as a passage for the entry and exit of materials using tower cranes, etc., by adopting a structure in which the movable roof slides horizontally after being sufficiently separated above the ventilation opening by a lifting operation, thereby allowing a large-area ventilation opening to be fully opened without interference between the surface of the fixed roof and the movable roof.

[0018] In addition, another objective of the present invention is to provide a soundproof house capable of preventing the detachment and fall-off of the movable roof and ensuring the durability of the driving device even in temporary construction site environments where strong winds or uneven loads are applied, by restraining the movable roof to move linearly only in the vertical direction through a combined structure of a guide rail and a guide shaft that guide the lifting and lowering of the movable roof. means of solving the problem

[0019] According to one aspect of the present invention for achieving the above objective, a soundproof house is provided, which is installed at a construction site, comprising: a fixed roof formed by including a soundproof panel and having one or more ventilation holes formed through it; a movable roof detachably coupled to the ventilation holes to open and close the ventilation holes; a lifting means for raising and lowering the movable roof in a vertical direction; and a sliding means for sliding the movable roof in a horizontal direction, wherein the movable roof is inserted into the interior of the ventilation holes in a closed position to form a plane identical to the outer surface of the fixed roof.

[0020] It is preferable that a sealing member be provided on at least one side of the outer surface of the movable roof or the inner surface of the ventilation opening, so that when the movable roof is in a closed position, the inner surface of the ventilation opening and the outer surface of the movable roof are compressed and sealed.

[0021] The lifting means comprises a lifting frame supporting the movable roof, a guide rail guiding the lifting frame in a vertical direction, a guide shaft coupled to move along the guide rail, and a lifting drive unit driving the guide shaft, wherein the lifting drive unit may be composed of one or more of a hydraulic actuator, a pneumatic actuator, and an electric actuator.

[0022] The above sliding means comprises a sliding rail installed horizontally on the structural frame of the soundproof house, a movable body movably coupled to the sliding rail, and a sliding drive unit for driving the movable body, wherein the sliding drive unit preferably comprises a rack gear arranged along the sliding rail, a pinion gear installed on the movable body and meshing with the rack gear, and a drive motor for rotating the pinion gear.

[0023] It is preferable that the above-mentioned movable roof operates in the order of being separated by a predetermined height or more in the vertical direction from the ventilation opening by the above-mentioned lifting means, then moving in the horizontal direction by the above-mentioned sliding means, and when returning to the above-mentioned closed position, moving to a vertically upward position of the ventilation opening by the above-mentioned sliding means, then lowering by the above-mentioned lifting means and being inserted into the ventilation opening.

[0024] A plurality of ventilation holes are formed in the fixed roof, and a movable roof corresponding to each ventilation hole may be configured to share a single sliding rail of the sliding means or to be driven individually by independent sliding rails.

[0025] It is desirable that a soundproof panel be provided on the upper surface of the above-mentioned movable roof, and that the soundproof panel be of the same specifications as the soundproof panel installed on the above-mentioned fixed roof, so that the soundproofing grade of the entire soundproof house is uniformly maintained regardless of whether it is opened or closed.

[0026] The lifting height of the movable roof by the lifting means is set to a height greater than that at which the movable roof, which moves by the sliding means, does not interfere with the upper surface of the fixed roof.

[0027] The above soundproof house may further include a sensing unit that detects one or more of the opening / closing state of the movable roof, internal air quality, internal temperature and humidity, wind speed, and wind direction, and a control unit that automatically controls the operation of the lifting means and sliding means based on the sensing signal of the sensing unit.

[0028] It is preferable that the control unit controls the lifting means and the sliding means to open the movable roof when the internal contamination concentration received from the sensing unit exceeds a set value or the internal temperature exceeds a set value, and controls the movable roof to automatically close when the wind speed received from the sensing unit exceeds a set value or rainfall is detected. Effects of the invention

[0029] The soundproof house according to the present invention adopts a structure in which a movable roof is inserted into the interior of a ventilation opening in a closed position to form a flat plane with the outer surface of a fixed roof and is pressed tightly against the inner circumference of the ventilation opening by a sealing member. This prevents any step difference or gap from occurring between the movable roof and the ventilation opening, thereby fundamentally blocking the path through which noise leaks to the outside. Accordingly, the soundproofing grade of the entire soundproof house is uniformly maintained regardless of whether the ventilation opening is open or closed, and rainwater penetration through the ventilation opening is prevented even during rainfall, ensuring rainwater blocking performance without the need for separate waterproofing treatment.

[0030] In addition, the present invention performs a two-stage opening operation in which the movable roof is vertically separated from the upper surface of the fixed roof by a lifting means and then moves horizontally by a sliding means, thereby allowing the entire area of ​​the ventilation opening to be fully opened without mechanical interference between the movable roof and the fixed roof. As a result, it can be utilized as a ventilation passage to quickly discharge exhaust gases and internal heat from heavy equipment, and can also be used as a passage for the entry and exit of materials and equipment using tower cranes, etc., thereby greatly improving work efficiency at the construction site.

[0031] Furthermore, by adopting a meshing method of a rack gear and a pinion gear as a sliding drive means, the present invention eliminates positional errors caused by rope elongation and slack that occurred in conventional rope and bobbin winding methods, thereby enabling precise control of the movable roof's movement position. Additionally, due to the meshing drive characteristics, reverse driving is suppressed even when eccentric loads or wind pressure are applied to the movable roof, preventing accidents such as the roof moving arbitrarily or falling off. Moreover, drive noise is significantly reduced compared to conventional rope methods, thereby minimizing noise complaints arising from the soundproof house itself.

[0032] In addition, by restraining the vertical movement of the lifting frame with a combined structure of a guide rail and a guide shaft, the present invention prevents the movable roof from flowing or detaching in directions other than the vertical direction, even in temporary construction site environments where strong winds or vibrations frequently occur, thereby ensuring structural safety and long-term durability of the driving device.

[0033] In addition, the present invention is equipped with a sensing unit that detects internal temperature, air quality, wind speed, wind direction, and rainfall, and a control unit that automatically controls a lifting means and a sliding means based on these, thereby optimizing ventilation performance by responding immediately to changes in the field environment and automatically closing the movable roof in the event of strong winds and rainfall, thereby reducing the burden of manual operation on field personnel and safely protecting internal equipment and workers.

[0035] Hereinafter, the configuration of a soundproof house according to a preferred embodiment of the present invention will be described in detail with reference to the attached drawings. However, the present invention is not limited to the embodiments described below, and it is understood that various modifications are possible within the scope of the technical concept of the present invention.

[0037] Referring to FIGS. 1 to 4, a soundproof house (10) according to one embodiment of the present invention comprises a house frame (20), a fixed roof (100) installed on the upper part of the house frame (20), a movable roof (200) that opens and closes a ventilation opening (110) formed in the fixed roof (100), a lifting means for raising and lowering the movable roof (200) in a vertical direction, and a sliding means for sliding the movable roof (200) in a horizontal direction.

[0038] The above soundproof house (10) is a temporary structure that surrounds a construction target area to block noise generated at a construction site, etc. from spreading to the outside. A ventilation opening (110) for ventilation and material entry / exit is formed in the roof portion, and when the ventilation opening (110) is closed, the movable roof (200) forms the same plane as the fixed roof (100), thereby simultaneously securing excellent soundproofing and waterproofing performance.

[0040] The above house frame (20) forms a structural support for the soundproof house (10) and includes a plurality of roof H-beams (21), a plurality of vertical H-beams (22), a horizontal reinforcing beam (23), a vertical reinforcing beam (24), and a reinforcing flat beam (25).

[0041] The above roof H-beams (21) extend horizontally along the left-right width direction of the soundproof house (10), and multiple of them are arranged side by side at regular intervals along the front-to-back length direction of the house. The upper surface of the roof H-beams (21) forms a triangular roof slope that slopes downward toward the front and rear sides with the ridge (30) as the center, and adjacent roof H-beams (21) are interconnected through roof H-beam connecting members (26) to secure the rigidity of the roof frame.

[0042] The vertical H-beam (22) is erected vertically from the ground and supports the lower ends of both sides of each roof H-beam (21). The horizontal reinforcing beam (23) connects adjacent vertical H-beams (22) in a horizontal direction to reinforce the lateral rigidity of the side frame, and the vertical reinforcing beam (24) is installed diagonally or vertically between the vertical H-beam (22) and the horizontal reinforcing beam (23) to distribute the load in the front-rear direction. The reinforcing flat steel (25) is attached to the joints or nodes of the frame to relieve stress concentration.

[0043] A roof vibration damping panel (27) is installed on the upper surface of the roof H-beam (21). The roof vibration damping panel (27) has a cross-section formed in a U-shape and is connected to the upper flange of the roof H-beam (21), absorbing vibrations transmitted from the roof surface to improve sound insulation performance.

[0045] The fixed roof (100) is a roof panel that is fixedly installed on the upper part of the roof H-beam (21) of the house frame (20), and forms a double-sloped roof shape that slopes downward toward the front and rear sides, respectively, centered on the ridge (30). The fixed roof (100) is formed of a composite panel material having soundproofing and waterproofing functions, and is fixedly seated on the upper surface of the roof H-beam (21) through a roof dustproof panel (27).

[0046] A ventilation opening (110) is formed through one side slope of the fixed roof (100), preferably in an area adjacent to the ridge (30). The ventilation opening (110) is a rectangular opening that penetrates the surface of the fixed roof (100) vertically and functions as a passage for ventilation inside the soundproof house (10) and for transporting materials using a crane, etc. The size of the ventilation opening (110) is formed to correspond to the external dimensions of the movable roof (200), so that when the movable roof (200) is lowered, it is inserted into the ventilation opening (110) and forms a plane identical to the surface of the fixed roof (100).

[0047] A sealing part (120) is provided on the inner edge of the ventilation opening (110). The sealing part (120) is formed from a packing material, preferably an elastic material such as rubber or silicone, and is continuously attached along the inner perimeter of the ventilation opening (110). When the movable roof (200) descends into the ventilation opening (110) and is placed in a closed position that forms the same plane as the fixed roof (100), the sealing part (120) seals the gap between the outer surface of the movable roof (200) and the inner surface of the ventilation opening (110) by a compression method, thereby blocking the infiltration of rainwater and the leakage of noise.

[0048] At the lower end of the eaves side of the fixed roof (100), that is, at the eave end where the roof slope ends downward, a rain gutter (130) is continuously installed along the front-to-back length direction of the roof. The rain gutter (130) is formed in the shape of a gutter with a semicircular or square cross section and an open top surface, and collects rainwater flowing down along the slope of the fixed roof (100) at the bottom of the roof. The rain gutter (130) is provided at each of the eave ends on both sides of the fixed roof (100) to independently collect rainwater drained from the front slope and the rear slope relative to the ridge (30).

[0049] A gutter (140) is vertically connected at a predetermined position along the length of the rainwater catcher (130), preferably near both ends. The gutter (140) is a pipe member with a circular cross-section, with its upper end connected to a drain formed on the lower surface of the rainwater catcher (130), and its lower end extending toward the ground along the outer surface of the vertical H-beam (22). The gutter (140) is fixed at regular intervals to the vertical H-beam (22) via a fixing bracket to ensure structural stability, and its lower end is guided to a drainage channel or sump on the ground to prevent rainwater from penetrating into the foundation of the soundproof house (10). The materials of the rainwater catcher (130) and the gutter (140) are formed from stainless steel or hot-dip galvanized steel with excellent corrosion resistance to ensure long-term durability in an outdoor environment.

[0051] The above-described movable roof (200) is a movable roof panel configured to enable lifting and sliding movements to open and close the ventilation opening (110). The above-described movable roof (200) has the same angle of inclination as the slope of the fixed roof (100) and is formed in a rectangular shape when viewed from a planar view. The upper surface of the above-described movable roof (200) forms a continuous plane without a step difference with the upper surface of the fixed roof (100) in the closed position, thereby forming a single smooth slope of the entire roof to ensure smooth drainage of rainwater and aesthetic appearance.

[0052] On both lower sides of the above-mentioned movable roof (200), that is, on both sides in the direction of the eaves, an operating space (210) that is open downward is formed. Each operating space (210) is a box-shaped receiving space extending downward from the lower surface of the movable roof (200), and driving components such as a lifting rail (300), roller (800), motor (700), and pinion (710), which will be described later, are received inside.

[0054] The above lifting means is configured to vertically raise the movable roof (200) from a closed position at the same height as the surface of the fixed roof (100) to a raised position protruding upward from the fixed roof (100), and comprises a pair of lifting rails (300), a guide rail (400), a guide shaft (310), and an actuator (600).

[0055] The above lifting rail (300) is a channel steel member with a cross-section formed in a U-shape and is provided on each side of the lower portion of the movable roof (200) at a distance from each other. Specifically, the lifting rail (300) is positioned in each operating space (210) formed in the direction of the eaves of the movable roof (200). Each lifting rail (300) is positioned so that the U-shaped opening faces outward in the horizontal direction and is coupled with a guide shaft (310) to be described later.

[0056] The guide rail (400) is a rod member having a hollow circular cross-section and is fixedly installed on the roof H-beam (21) of the house frame (20) in an upright position. A pair of guide shafts (310) are formed protruding from both sides of each lifting rail (300), and the guide shafts (310) are fitted into the inner circumference of the guide rail (400) and connected so as to slide in the up and down direction. As a result, the lifting rail (300) is guided only in the vertical direction along the guide rail (400), thereby preventing movement in the front, back, left, and right directions during the lifting process of the movable roof (200).

[0057] The actuator (600) is a hydraulic or electric linear drive device and is fixedly installed on the roof H-beam (21) of the house frame (20), but is fixed to a roof H-beam (21) different from the roof H-beam (21) to which the guide rail (400) is fixed. The operating rod of the actuator (600) is connected to the lifting rail (300), and when the actuator (600) extends, the lifting rail (300) rises along the guide rail (400), and in conjunction with this, the entire movable roof (200) rises vertically upward above the fixed roof (100). Conversely, when the actuator (600) retracts, the movable roof (200) descends and is inserted into the ventilation opening (110).

[0059] The above sliding means moves the movable roof (200) in a raised position along the surface of the fixed roof (100) in a horizontal direction to fully open the ventilation opening (110), and includes a rack (320, 510), a pinion (710), a motor (700), a motor case (720), a fixed rail (500), and a roller (800).

[0060] A rack (320) is formed along the length of the side of the above-mentioned lifting rail (300). The rack (320) has teeth formed continuously over a section corresponding to the entire length of the lifting rail (300), and meshes with the pinion (710) described later to form a horizontal movement force transmission path for the movable roof (200).

[0061] The fixed rail (500) is a channel steel member with a cross-section formed in a U-shape, and a pair is provided parallel to each other along the slope direction of the roof slope on the surface of the fixed roof (100). The fixed rail (500) is arranged so as to be aligned on the same axis as the lifting rail (300) when the movable roof (200) is placed in the raised position, thereby forming a path through which the roller (800) can continuously travel from the lifting rail (300) to the fixed rail (500). A rack (510) is also formed along the length direction on the side of the fixed rail (500), and the rack (510) forms a continuous toothed path with the rack (320) on the lifting rail (300) side, enabling the pinion (710) to travel without interruption along the entire section from the lifting rail (300) to the fixed rail (500).

[0062] The motor (700) is an electric motor installed inside the operating space (210) of the movable roof (200), and a pinion (710) is coupled to the output shaft. The pinion (710) is a small gear that meshes with a rack (320, 510), and converts the rotational force of the motor (700) into linear motion to move the movable roof (200) in a horizontal direction. A motor case (720) is provided on the outside of the motor (700) to protect the motor (700) from external dust and moisture.

[0063] The rollers (800) are rotatably installed in pairs within each operating space (210) of the movable roof (200). The rollers (800) are fitted into the U-shaped channel of the lifting rail (300) and roll along the inner surface of the channel, and when the movable roof (200) moves horizontally, they travel with low friction along the inside of the lifting rail (300) and the fixed rail (500) to assist in smooth sliding operation. A pair of rollers (800) are accommodated together with a motor (700) and a pinion (710) in the operating space (210) on the side where the rack (320) is formed, and a pair of rollers (800) are also accommodated in the operating space (210) on the opposite side where the rack is not formed, so that both sides of the movable roof (200) are supported in a balanced manner.

[0065] An inspection ladder (900) is installed on one side of the interior of the soundproof house (10), preferably on the wall side adjacent to the ventilation opening (110). The inspection ladder (900) is intended for a worker to safely ascend from the ground to a height near the ceiling of the soundproof house (10), that is, close to the lower surface of the fixed roof (100) and the lower surface of the movable roof (200), while visually inspecting the operating condition of the movable roof (200) or performing maintenance work.

[0066] The inspection ladder (900) has a stepped structure in which a plurality of step plates (910) are arranged in a zigzag shape in the vertical direction. Specifically, the plurality of step plates (910) are fixedly supported by a vertical H-beam (22) or a horizontal reinforcing beam (23), and adjacent upper and lower step plates (910) are arranged to be opposite each other in the horizontal direction, forming a zigzag path when viewed from the side. That is, when the lower first step plate (910) is located on the left, the upper second step plate (910) is located on the right, and then the upper third step plate (910) is located on the left, and so on, alternating and repeating to form a zigzag movement path overall. Through this zigzag arrangement, the horizontal occupied area of ​​the inspection ladder (900) is minimized, while the incline between each step plate (910) is maintained gently, enabling safe ascent and descent for the worker.

[0067] A handrail (920) is installed vertically on the outer edge of each step (910). The handrail (920) is provided on both sides or the open side of the step (910) to prevent a worker from falling, and is fixed to a vertical H-beam (22) or a horizontal reinforcing beam (23) to ensure structural stability. The uppermost step (910) of the inspection ladder (900) is positioned at a height close to the lower surface of the fixed roof (100), so that when a worker reaches the uppermost step, it is possible to access the drive unit, such as the lifting rail (300), roller (800), motor (700), and pinion (710), provided at the bottom of the movable roof (200), to perform inspection and maintenance work.

[0069] The movable roof (200) of the soundproof house (10) having the above configuration is opened in the following order.

[0070] First, in the closed state, the movable roof (200) is inserted into the interior of the ventilation opening (110) to form a plane identical to the surface of the fixed roof (100), and the gap between the ventilation opening (110) and the movable roof (200) is sealed by the sealing part (120).

[0071] When opening is required, the actuator (600) is extended, causing the lifting rail (300) to move vertically upward along the guide rail (400), and in conjunction with this, the movable roof (200) protrudes above the surface of the fixed roof (100). When the movable roof (200) reaches a predetermined height, the lifting rail (300) is aligned on the same axis as the fixed rail (500) placed on the surface of the fixed roof (100).

[0072] Afterward, when the motor (700) is activated, the pinion (710) rotates along the rack (320), and the movable roof (200) slides along the roof slope direction on the fixed roof (100). During this process, the roller (800) travels continuously along the U-shaped channel connecting the lifting rail (300) to the fixed rail (500), and the pinion (710) travels while continuously engaging with the rack (320) on the lifting rail (300) side and the rack (510) on the fixed rail (500) side. When the movable roof (200) is completely removed from the ventilation opening (110), the ventilation opening (110) is fully opened, allowing ventilation of the inside of the soundproof house (10) or the entry and exit of materials.

[0073] The closing operation is performed in the reverse order of the opening operation. That is, the motor (700) is driven in the reverse direction to return the movable roof (200) to the upper side of the ventilation opening (110), and then the actuator (600) is retracted to lower and insert the movable roof (200) into the ventilation opening (110). Once the lowering is complete, the movable roof (200) forms the same plane as the fixed roof (100) again, and the gap is sealed by the sealing part (120), thereby restoring the soundproofing and waterproofing functions.

[0075] The soundproof house (10) according to the present invention having the configuration described above achieves technical problems that could not be solved in the prior art through the following operation.

[0076] First, the soundproofing and waterproofing effects according to the sealed structure of the movable roof (200) will be explained. When the movable roof (200) is lowered into the ventilation opening (110) and placed in a closed position, the upper surface of the movable roof (200) forms a continuous flat plane with the upper surface of the fixed roof (100) without any step difference. At the same time, the sealing part (120) continuously attached to the inner edge of the ventilation opening (110) adheres to the outer surface of the movable roof (200) with a uniform compressive force over the entire perimeter. At this time, the elastic material, such as rubber or silicone, constituting the sealing part (120) is elastically deformed by the insertion force caused by the lowering of the movable roof (200), and fills even the minute gaps between the inner surface of the ventilation opening (110) and the outer surface of the movable roof (200), thereby fundamentally blocking the propagation path through which noise leaks to the outside. In conventional technology, a structure was adopted in which the movable roof simply slid horizontally on the upper surface of the fixed roof, so a step and gap inevitably occurred between the movable roof and the fixed roof in the closed position. However, the present invention fundamentally resolves this problem by adopting a structure in which the movable roof (200) is inserted into the internal space of the ventilation opening (110). In addition, since rainwater does not stagnate on the roof surface forming the same plane and flows down smoothly along the slope, rainwater infiltration through the ventilation opening (110) is prevented even without additional waterproofing treatment.

[0078] Next, the ventilation and material loading / unloading operations according to the two-stage opening operation are described. The movable roof (200) first rises vertically upward above the fixed roof (100) by means of an actuator (600), and then performs a two-stage opening operation by sliding horizontally along the surface of the fixed roof (100) by means of a motor (700) and a pinion (710). Since the movable roof (200) is completely separated from the edge of the ventilation opening (110) by the vertical rising operation of the first stage, the phenomenon of mechanical interference between the lower surface or side of the movable roof (200) and the edge of the ventilation opening (110) or the sealing part (120) of the fixed roof (100) does not occur during the horizontal sliding process of the second stage. Due to this non-interference open structure, wear and damage to the sealing part (120) are prevented, so the sealing performance is maintained for a long period even with repeated opening and closing operations. Since the entire opening area of ​​the ventilation opening (110) is completely open without any obstacles, a large-area ventilation passage is secured to quickly discharge exhaust gases, airborne dust, and internal heat from heavy equipment to the outside. In addition, when the ventilation opening (110) is in a fully open state, it can also be used as a vertical access passage for construction materials, aggregates, and heavy equipment parts using lifting equipment such as a tower crane. Therefore, efficient material input through the roof is possible without the need to open the side of the soundproof house (10) or form a separate access opening, thereby shortening the work path at the construction site and improving overall construction efficiency.

[0080] Next, the precision control operation according to the meshing drive method of the rack (320, 510) and pinion (710) is explained. The pinion (710) coupled to the output shaft of the motor (700) rotates while continuously meshing with the rack (320) on the lifting rail (300) side and the rack (510) on the fixed rail (500) side, and this rotational motion is converted into accurate linear motion through the tooth profile of the rack (320, 510), so that the horizontal movement position of the movable roof (200) is precisely controlled in proportion to the rotation angle of the pinion (710). In the rope and bobbin winding method adopted in the prior art, elongation and relaxation due to repeated use are inevitable due to the material characteristics of the rope, so an accumulated error occurs between the actual movement distance of the movable roof and the commanded movement distance; however, since the driving force is transmitted by rigid contact between metal tooth profiles in the gear meshing method of the present invention, such positional error is fundamentally eliminated. In addition, the meshing structure of the rack and pinion has a self-locking characteristic in which reverse driving is naturally suppressed by the interlocking friction of the teeth, so even if a wind pressure load or eccentric load caused by strong winds is applied to the movable roof (200), accidents such as the movable roof (200) being pushed in an unintended direction or falling off are prevented. Furthermore, since the driving noise caused by the gear meshing is significantly lower than the friction noise and impact noise generated when the rope is wound and unwound on the bobbin, the operating noise of the soundproof house (10) itself is reduced, and noise complaints regarding nearby residential areas are minimized.

[0082] Next, the lifting guidance action according to the combined structure of the guide rail (400) and the guide shaft (310) will be explained. The guide shaft (310), which is formed protruding from both sides of each lifting rail (300), is fitted into the hollow inner surface of the guide rail (400), allowing sliding only in the vertical direction, while horizontal movement is restricted by the inner surface of the guide rail (400). Due to this combined structure, movement and rotation in the forward, backward, left, and right directions during the lifting process of the movable roof (200) are completely suppressed, so the movable roof (200) moves accurately in a straight line along a set vertical path. At construction sites, various external forces such as building wind caused by high-rise structures, vibration caused by tower crane operations, and ground vibration caused by the operation of nearby heavy equipment act simultaneously. The combined structure of the guide rail (400) and the guide shaft (310) has the effect of stably maintaining the lifting trajectory of the movable roof (200) even under the harsh environmental conditions of such construction sites, thereby preventing eccentric wear of the drive device and ensuring long-term durability.

[0084] Next, the sliding assist action by the roller (800) is described. The roller (800) is rotatably installed in pairs within the operating spaces (210) on both sides of the movable roof (200), and travels while making rolling contact along the inside of the U-shaped channels of the lifting rail (300) and the fixed rail (500) during horizontal movement of the movable roof (200). Due to the rolling contact of the roller (800), the contact friction between the movable roof (200) and the rail is converted from sliding friction to rolling friction, so the driving load applied to the motor (700) is significantly reduced, making it possible to smoothly move the large-area movable roof (200) even with a small motor. In addition, since a pair of rollers (800) are balancedly arranged on each side of the movable roof (200), the self-weight and external forces acting on the movable roof (200) are distributed and supported on both sides, preventing localized wear of the rail due to uneven load.

[0086] Next, the drainage function by the rain catcher (130) and the gutter (140) will be explained. The rain catcher (130), installed at the eaves ends on both sides of the fixed roof (100), collects rainwater flowing down from the front slope and the rear slope respectively with respect to the ridge (30) and directs it to the gutter (140). The gutter (140) extends toward the ground along the outer surface of the vertical H-beam (22) to safely discharge the collected rainwater to a drainage channel or a sump on the ground. Through this independent double drainage path, rainwater is prevented from penetrating the foundation of the soundproof house (10) and weakening the ground even during rainfall, and the steel members of the house frame (20) are prevented from being continuously exposed to rainwater and corroding.

[0088] Next, the maintenance operation by the inspection ladder (900) is described. Since the multiple step plates (910) of the inspection ladder (900) form a zigzag structure in which adjacent upper and lower step plates (910) are arranged to be opposite each other in the horizontal direction, the horizontal occupied area of ​​the inspection ladder (900) on the wall surface is significantly reduced compared to a straight ladder or a spiral staircase. As a result, the workspace inside the soundproof house (10) is maximized, and the worker can safely access the height of the lower surface of the fixed roof (100), making it possible to quickly perform maintenance work on-site, such as regular inspection and parts replacement of drive components including the elevator rail (300), motor (700), pinion (710), and roller (800) under the movable roof (200). The handrail (920) provided on the outer edge of each step plate (910) prevents the worker from falling, thereby ensuring safety during high-altitude work.

[0090] As described above, the soundproof house (10) according to the present invention simultaneously implements opposite functions of same-plane closure and complete opening in a single roof structure through the insertable sealing structure of the movable roof (200), ensures safe opening and closing operation of the movable roof (200) even under harsh environmental conditions at the construction site through the meshing drive method of the rack and pinion and the combined structure of the guide rail and guide shaft, and provides a temporary soundproof house for a construction site that comprehensively satisfies soundproof performance, waterproof performance, ventilation performance, structural safety, and maintenance convenience by combining a systematic drainage structure through a rain gutter and a gutter and efficient maintenance accessibility through a zigzag inspection ladder.
