Description

Technology Field

[0001] The present invention relates to an infill box for modular construction equipped with a heating-integrated floor for reducing inter-floor noise and a method for manufacturing the same. More specifically, the invention relates to an infill box for modular construction equipped with a heating-integrated floor for reducing inter-floor noise and a method for manufacturing the same, wherein a plurality of shock-absorbing frames are installed on the bottom portion of an infill frame forming the frame of the infill box to form a grid-shaped installation space, and support panels, insulation panels, pipe installation blocks, and finishing panels are installed inside and above the installation space to form a dry heating floor structure and an inter-floor noise reduction structure. Background Technology

[0002] With the implementation of the Serious Accidents Punishment Act, there is a rising demand for technologies aimed at preventing on-site accidents by minimizing on-site work and shortening construction periods in domestic construction sites. Additionally, due to the rapid rise in on-site labor costs, efforts are being made to reduce overall labor costs by increasing the proportion of production carried out in factories rather than on-site.

[0003] Accordingly, the need for developing off-site construction technologies as part of smart construction technology is being emphasized at construction sites, and modular construction is recognized as a technological alternative capable of resolving various problems occurring at domestic construction sites.

[0004] Generally, modular construction involves manufacturing each part of a building as a module in a factory, transporting the manufactured modules to the site, and assembling them there to construct the building in a short period of time. While this method has the advantage of reducing on-site work and shortening the construction period, existing modular construction methods have limitations, such as being steel-based and, above all, having construction costs that are more than 150% higher than those of the existing RC method in terms of economic efficiency.

[0005] Recently, construction methods are being attempted both domestically and internationally to replace expensive steel by stacking precast unit modules to form the framework of a building and finishing the interior and exterior on-site, but the proportion of pre-fabrication (prefab) is only about 50%.

[0006] Meanwhile, a PC modular that significantly increases the prefabrication rate and minimizes on-site work is disclosed in the applicant's prior registered patent, Korean Patent No. 10-2149248 (registered on August 24, 2020, hereinafter referred to as the 'prior art document'), and the PC modular structure according to the prior art document includes a PC module (10) and a 3D infill box (20) as shown in FIG. 1.

[0007] The above PC module (10) serves as the frame of a building and includes a bottom portion (11) and a pair of first side portions (12) formed integrally and upright on both sides of the bottom portion (11), and an insertion portion (13) into which a 3D infill box (20) is inserted is formed between the pair of first side portions (12). Such a PC module (10) is extended in one direction and is formed to have an open U-shape at both ends in the longitudinal direction without separate beams.

[0008] The above 3D infill box (20) serves as an interior finishing material and is formed in the shape of a box including a front part (21), a rear part (22), a pair of second side parts (23), and a top part (24), and is installed in the insertion part (130) of the PC module (10) to form a PC module together with the PC module (10).

[0009] The PC modular of the prior art literature described above can be made lighter by reducing its own weight through the use of a three-sided PC module (10), and the construction of the building can be increased by bringing the PC module (10) and 3D infill box (20) manufactured in the factory to the site and assembling them.

[0010] Meanwhile, wet heating or dry heating may be applied to the above 3D infill box (20), but in the case of wet heating, which involves installing insulation and heating pipes and then finishing with cement, there is a disadvantage that the weight of the 3D infill box (20) increases significantly, so it is preferable to apply prefabricated dry heating.

[0011] However, in order to apply prefabricated dry heating to the above 3D infill box (20), a floor frame must be installed on the bottom of the 3D infill box (20), and an insulation panel, a heating panel, and a finishing panel must be installed on the floor frame, which has the disadvantage that the thickness of the bottom part of the 3D infill box (20) becomes considerably thick.

[0012] In this way, when a 3D infill box (20) with a thickened floor section due to the introduction of a prefabricated dry heating system is inserted into a PC module (10), the floor section thickness of the 3D infill box (20) and the thickness of the heating system are added to the slab thickness of the PC module (10), resulting in a lower overall floor height and reduced space utilization, and there is a problem of reduced economic efficiency due to increased material costs.

[0013] Furthermore, although not shown in FIG. 1, steel spacers are generally installed along the longitudinal direction of the slab of the PC module (10), and a 3D infill box (20) is mounted on top of the spacers. Accordingly, a triple stacked structure of spacers, infill boxes, and floor frames is formed, which further increases the amount of steel used and causes a problem of reduced space utilization.

Specific details for implementing the invention

[0033] In the following, preferred embodiments of the present invention will be described in detail based on the details illustrated in the drawings; however, specific descriptions of related known functions or configurations are omitted if it is determined that such descriptions may unnecessarily obscure the essence of the present invention.

[0034] An infill box (100) for modular construction equipped with a heating integrated floor for reducing inter-floor noise according to one embodiment of the present invention is inserted and installed in the insertion space (210) of a box-shaped PC module (200) as shown in FIG. 2 and is used to construct a modular building, wherein a plurality of side wall sections (102) are integrally provided around the perimeter of the floor section (101), and the upper ends of the side wall sections (102) are connected to each other by a ceiling section (103).

[0035] In this way, the side wall (102) of the infill box (100), which is formed by integrating the bottom part (101), a plurality of side wall parts (102), and the ceiling part (103), can be fitted with a window or door or closed off with a wall. Of course, a window or door can also be installed in the side wall part (102) and the ceiling part (103) in correspondence with the PC module (200).

[0036] Meanwhile, an infill box (100) according to one embodiment of the present invention includes an infill frame (110) made of steel so that a dry heating floor structure and an inter-floor noise reduction structure can be integrally formed in the floor portion (101). As shown in FIGS. 2 and 3, the infill frame (110) includes a plurality of outer frames (111) assembled in a box shape to form the floor portion (101), side wall portion (102), and ceiling portion (103) of the infill box (100), and a plurality of shock-absorbing frames (120) installed to form a plurality of installation spaces (IS) inside the outer frames (111) forming the floor portion (101).

[0037] An outer wall panel (112) may be installed on the outer side of the outer frame (111) forming the side wall portion (102) and the ceiling portion (103) to close it, and an opening frame may be installed in the frame space portion (FS) provided between the outer frame (111) and the outer wall panel (112) to form various facilities for electricity, ventilation, cooling, etc., as well as windows or doors, and a foam insulation material may be sprayed into the frame space portion (FS) to provide insulation, and a finishing panel (113) may be installed on the inner side to provide finishing.

[0038] Meanwhile, the shock-absorbing frame (120) is installed in a cross-sectional manner on the inner side of the outer frame (111) forming the bottom part (101) of the infill box (100) to form a plurality of installation spaces (IS) in a grid shape, and as shown in FIG. 4, a support panel (130) and an insulation panel (140) are installed in a stacked manner in each of the plurality of installation spaces (IS), and a pipe installation block (150) that supports a heating pipe (160) and a finishing panel (170) are installed in a stacked manner on the upper part of the shock-absorbing frame (120), so that the dry heating floor structure and the inter-floor noise reduction structure can be integrally provided in the infill frame (110).

[0039] The shock-absorbing frame (120), which is installed on the inner side of the outer frame (111) to form part of the dry heating floor structure and the inter-floor noise reduction structure as shown in FIGS. 4 and 5, includes a fastening part (121), a pair of panel guide parts (122), a pair of seating parts (123), a pair of gap forming parts (124), and a pair of support parts (125) so as to stably support the support panel (130), the insulation panel (140), and the pipe installation block (150) to absorb shock and reduce noise, and a damping chamber (126) for shock absorption and noise reduction is formed inside.

[0040] More specifically, the fastening part (121) is formed on the upper end of the shock-absorbing frame (120) to support the bottom surface of the pipe installation block (150) from below, and the pipe installation block (150) placed on the upper end of the fastening part (121) is fastened with a screw and fixed to the fastening part (121).

[0041] The above pair of panel guide sections (122) are formed by bending both ends of the fastening section (121) vertically downward so as to guide the support panel (130) and the insulation panel (140) to the correct position, facing the sides of the support panel (130) and the insulation panel (140). The above pair of seating sections (123) are formed by bending the lower ends of each panel guide section (122) horizontally outward so that the end of the support panel (130) can be seated and supported. The above pair of gap forming sections (124) are formed by bending the outer ends of each seating section (123) vertically downward so that the air gap (AG), which will be described later, can be formed at a sufficient height.

[0042] Additionally, the upper end of each spacing member (124) is bent inward so as to close the internal space formed by the fastening member (121), the pair of panel guide members (122), the pair of seating members (123), and the pair of spacing members (124), and to be supported by the anti-vibration pad (180).

[0043] The shock-absorbing frame (120) formed in this manner has a damping chamber (126) formed inside, which is closed by a fastening part (121), a panel guide part (122), a seating part (123), a spacing part (124), and a support part (125), and is installed so as to intersect each other in longitudinal and transverse directions to form a plurality of grid-shaped installation spaces (IS) on the inner side of the outer frame (111).

[0044] At this time, a vibration damping pad (180) is installed on the bottom surface of the intersection where the shock-absorbing frames (120) intersect each other, and the vibration damping pad (180) is interposed between the shock-absorbing frames (120) and the slab of the PC module (200) to mitigate the shock transmitted from the shock-absorbing frames (120) and transmit it to the PC module (200), thereby reducing the floor impact sound transmitted to the slab of the PC module (200). In addition, the inner end of the support portion (125) is bent upward to form a reinforcing piece (128) that protrudes upward from inside the damping chamber (126), thereby increasing the cross-sectional force of the shock-absorbing frames (120) to secure rigidity and prevent deformation due to load. In particular, the reinforcing member (128) is implemented using roll forming of steel, so that horizontal forces transmitted from the load are mutually offset by the reinforcing member (128), thereby enabling more stable support.

[0045] Thus, according to the present invention, a single shock-absorbing frame (120) can primarily form the skeleton of an infill box (100), and secondarily function as a spacer between the infill box (100) and the slab of a PC module (200). Furthermore, since it functions as a shock-absorbing member constituting a dry heating system, a single shock-absorbing frame (120) can replace all the functions that were individually formed in conventional infill fixes. This prevents the overall floor height from being lowered, thereby increasing space utilization. Additionally, by minimizing the installation of additional frames, the amount of metal used is reduced, making it economical and lightweight.

[0046] Meanwhile, a plurality of sound-absorbing holes (127) are formed in the panel guide portion (122) to induce noise of a specific frequency to flow into the damping chamber (126), and depending on the size of the suction hole (127), the noise of a specific frequency flowing into the damping chamber (126) is reflected multiple times inside the chamber (126) and simultaneously absorbed and canceled out by the air, so that inter-floor noise can be reduced more effectively.

[0047] At this time, mineral wool or glass wool is inserted into the interior of the shock-absorbing frame (120) so as to be guided by a reinforcing piece (128) to improve thermal insulation performance and to more effectively absorb noise introduced through the suction hole (127).

[0048] The above support panel (130) closes the bottom of each installation space (IS) and is positioned inside the installation space (IS) to form an air gap (AG) by being spaced apart from the slab of the PC module (200), and its end is seated on the seating portion (123) of the shock-absorbing frame (120) and is fixed to the shock-absorbing frame (120) by screw fastening.

[0049] Meanwhile, a support panel (130) installed in an installation space (IS) formed between the outer frame (111) and the shock-absorbing frame (120) may have a portion of which is seated on an angle bracket (AB) installed on the outer frame (111) and may be fixed to the angle bracket (AB) by screw fastening.

[0050] OSB (Oriented Strand Board) plywood can be used as such a support panel (130) so that the increase in weight of the infill box (100) can be minimized.

[0051] The insulation panel (140) is installed in each installation space (IS) so as to be stacked on top of the support panel (130), and an expanded polystyrene insulation panel or a compressed polystyrene insulation panel may be used as the insulation panel (140).

[0052] Meanwhile, it is preferable that the height (H) of the panel stack formed inside the installation space (IS) by stacking the support panel (130) and the insulation panel (140) is formed to be the same as the height of the panel guide part (122).

[0053] As shown in FIGS. 6 and 7, the pipe installation block (150) is made of a synthetic resin block having a plurality of fixing protrusions (151) formed protruding from the upper surface to fix the heating pipe (160), and a plurality of pipe installation blocks (150) modularized in the same form are combined and installed to form a pipe support layer on the upper surface of the insulation panel (140). In addition to the part where the heating pipe (160) is installed, an air layer is formed by the plurality of fixing protrusions (151) in the pipe installation block (150), so the thermal insulation performance and shock absorption performance can be further improved.

[0054] In addition, a heat conduction plate (190) made of a metal with high thermal conductivity may be installed on the upper part of the pipe support layer formed by combining the plurality of pipe installation blocks (150) to diffuse heat emitted from the heating pipe (160) to the surroundings.

[0055] The heating pipe (160) is inserted and fixed between the connecting protrusions (151) formed in the pipe installation block (150), and is laid so that heating water can circulate throughout the bottom portion (101) of the infill box (100). At this time, a fitting groove is integrally formed in the heat conduction plate (190) for the heating pipe (160) to be seated, so that it can be inserted between the connecting protrusions (151) together with the heating pipe (160).

[0056] The above finishing panel (170) is installed on the upper part of the pipe installation block (150) to form a floor finishing layer on the upper part of the pipe support layer as shown in FIG. 4. For this finishing panel (170), a magnesium board with high thermal conductivity, excellent heat storage performance, and high strength may be used.

[0057] Meanwhile, a method for manufacturing an infill box (100) for modular construction according to one embodiment of the present invention is to manufacture an infill box (100) for modular construction equipped with a floor integrated for inter-floor noise reduction and heating configured as above, and includes an infill frame forming step (S100), an exterior wall panel installation step (S200), a utility installation step (S300), an insulation foaming step (S400), and an interior finishing step (S500), as shown in FIG. 8.

[0058] The above infill frame forming step (S100) is a process for manufacturing an infill frame (110) that forms the framework of the bottom part (101), side wall part (102), and ceiling part (103) of the infill box (100). As shown in FIG. 3, a plurality of outer frames (111) made of square tubes are combined in a box shape to form a structure having a three-dimensional shape of a cuboid, and a plurality of shock-absorbing frames (120) are intersected on the inside of the outer frames (111) combined to form the bottom part (101) so that a plurality of installation spaces (IS) are formed, thereby manufacturing an infill frame (110) in which a plurality of installation spaces (IS) are provided in a grid shape on the bottom part.

[0059] The above-mentioned outer wall panel installation step (S200) is a process of installing an outer wall panel (112) on the outside of an outer frame (111) that forms a side wall portion (102) and a ceiling portion (103). The outer wall panel (112) may be made of steel plate and may be fixed to the outer frame (111) by welding or bolting.

[0060] Meanwhile, the space between adjacent exterior wall panels (112) can be taped to improve airtightness.

[0061] The above utility installation step (S300) is a process of installing various equipment and an opening frame in a frame space (FS) provided between an outer frame (111) and an outer wall panel (112) that form a side wall section (102) and a ceiling section (103). The various equipment may include wires for supplying electricity, pipes for ventilation and cooling, etc., and the opening frame may include a frame for installing windows or doors.
