Description

Technical Field

[0001] The present invention relates to the technical field of building design and construction, and in particular to a non-destructive disassembly integrated lightweight exterior wall and an installation method thereof. Background Art

[0002] With the rapid development of prefabricated steel structures, systematic research into technologies aimed at improving their functionality and sustainable performance is ongoing. The exterior envelope (exterior walls, roofs, doors, windows) and its connections to the main steel structure significantly impact a building's seismic, wind, fire, waterproofing, sound, and thermal performance. The exterior wall is the most crucial component of the exterior envelope.

[0003] Steel supports are not part of the exterior wall structure; they are part of the main structure. While steel frame-support systems are common, exterior walls that effectively adapt to them are rare. Existing exterior walls, when confronted with steel supports, are essentially fragmented, requiring complex construction and manufacturing processes, resulting in a waste of labor.

[0004] In actual construction projects, the performance index requirements for building exterior walls will vary depending on the usage scenarios. For example, in high-altitude mountainous areas, winter snow sports events and other environments, the exterior walls are required to meet the needs of user comfort in low-temperature environments, be able to be quickly erected in high-altitude, windy mountainous areas, and be able to be disassembled without loss and reused in other places. In other words, comprehensive requirements are put forward for the thermal performance, safety, wind resistance and other properties of the exterior walls and the rapid installation and non-destructive disassembly of their connection nodes.

[0005] At present, the exterior wall products that are widely used in prefabricated steel structure buildings on the market include prefabricated wall panels, on-site assembled composite wall panels, building curtain walls, etc. Among them, typical representative products of prefabricated wall panels include autoclaved aerated concrete panels, precast concrete exterior wall panels, etc.

[0006] Among the common exterior wall panel products mentioned above, prefabricated wall panels generally have a large deadweight, making them inconvenient to transport and install in environments with poor infrastructure conditions such as mountainous areas, and they cannot be disassembled and reused without damage; most composite wall panels assembled on-site require wet operations on-site or have special requirements for on-site construction machinery and personnel, making construction difficult in high-altitude and cold environments; building curtain walls have high economic costs, limited scope of application, and complex on-site construction, making them unsuitable for large-scale promotion in prefabricated steel structure buildings.

[0007] In summary, in order to enhance the adaptability of prefabricated steel structure buildings in various climatic environments, expand their scope of application, and realize the tiered recycling of resource materials throughout the life cycle of the building, it is necessary to develop an exterior wall product that has a high degree of factory assembly, a light weight, can be disassembled without damage, and can adapt to various environments while meeting the basic performance index requirements.

[0008] It is also necessary to consider whether the exterior wall can form a stable support with the prefabricated steel structure. Summary of the Invention

[0052] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings, wherein the accompanying drawings constitute a part of the present invention and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not used to limit the scope of the present invention.

[0053] Combine Figures 1 to 6 In a more specific embodiment, the exterior wall and installation method of the present invention are described, wherein the inside and outside are consistent with the directions of indoor and outdoor. The following is a detailed description:

[0054] The non-destructively disassembled integrated lightweight exterior wall of the present invention can be used to directly connect with the steel beams and steel columns 16 of the main body of the building structure at the construction site, and can adapt to the installation and construction of building structures in various environments.

[0055] As attached Figures 1 to 4 As shown, the integrated lightweight exterior wall consists of 7 layers, from the exterior to the interior:

[0056] The first layer is constructed as an exterior wall decorative panel 1.

[0057] The exterior wall decorative panel 1 can be a cement fiber decorative panel, a silicate cover board, an ALC board with a decorative surface, etc. In this embodiment, the cement fiber decorative panel is preferably used.

[0058] The second layer is constructed as a connecting plate 2 .

[0059] The connecting plate 2 can be made of wood board, wood-plastic board, or other materials. The connecting plate 2 forms a frame structure, and several horizontal and vertical keels can be added to increase structural rigidity and strength, serving as a connection and as a thermal bridge. In this embodiment, the connecting plate 2 is preferably made of wood board, and vertical keels are used in the frame structure to reduce overall weight and increase strength. In this embodiment, wood board is the preferred material, and wood-plastic board is preferred.

[0060] The third layer is a waterproof and breathable membrane 3.

[0061] The waterproof breathable membrane 3 is installed close to the exposed side of the connecting plate 2 to form the outer structural layer. The waterproof breathable membrane is a new type of polymer waterproof material. The construction of the waterproof breathable membrane meets the following requirements:

[0062] (1) The surface of the base layer should be clean and firm, without any sharp protrusions;

[0063] (2) The laying should start from the bottom side of the exterior wall, and be laid horizontally from bottom to top along the building facade, and overlap along the direction of water flow;

[0064] (3) The horizontal overlap width of the waterproof breathable membrane shall not be less than 100mm, and the longitudinal overlap width shall not be less than 140mm. The longitudinal overlap seams of two adjacent membranes shall be staggered with a spacing of not less than 500mm. The overlap seams shall be covered and sealed with sealing tape;

[0065] (4) The waterproof breathable membrane should be fixed as it is laid. A small piece of sealing adhesive tape should be pasted on the fixed part in advance. The waterproof breathable membrane should be fixed on the base layer with a plastic anchor bolt with a plastic gasket. There should be no less than 3 fixing points per square meter.

[0066] (5) The waterproof breathable membrane laid in the window hole or other opening is cut into an "I" shape and fixed to the inside of the opening with sealing tape; the connection with the door and window frame is fully sealed with matching sealing tape, and the four corners are sealed with sealing materials;

[0067] (6) Use sealing tape to seal the surrounding areas of the connectors that penetrate the waterproof and breathable membrane.

[0068] The 4th layer is constructed of a metal frame.

[0069] The metal frame includes a metal frame keel 4, several cross-bracing keels 5, and several inner frame keels 6. The metal frame keel 4 is a C-shaped channel steel with bolt holes 10 reserved on all four sides and bolt installation holes 11 reserved on both sides. It is used to connect the integrated lightweight exterior wall to the steel beams and steel columns 16 of the main building structure of the prefabricated steel structure via bolts 13.

[0070] The insulation board 7 is firmly embedded in each frame grid of the metal frame keel 4 in blocks.

[0071] Preferably, the metal frame keel 4 and the indoor keel frame 9 are reinforced at corresponding positions, which are respectively a first double-embracing C-shaped keel and a second double-embracing C-shaped keel made by relatively fixing two C-shaped channel steels. Figure 5 As shown in the figure, the first double-clad C-shaped keel, like the internal keel 6, is spliced ​​to the horizontal keel 5 inside the metal frame keel 4 using self-tapping screws. It is then set through to become the vertical keel of the metal frame keel 4 and connected to the upper and lower frames of the metal frame keel 4 using self-tapping screws. The second double-clad C-shaped keel is fixed to the upper and lower frames of the indoor keel frame 9 using self-tapping screws.

[0072] The first double-arm C-shaped keel and the second double-arm C-shaped keel serve as reinforcing keels, which increase the rigidity and strength of the entire integrated lightweight exterior wall. They are optional structures of the integrated lightweight exterior wall and are only used in parts of the wall panel where there are special force requirements. C-shaped channel steel is used, and the cross-sectional size is smaller than the C-shaped channel steel cross-sectional size of the metal frame keel 4 and the cross-bracing keel 5, so that they can be embedded in the metal frame without structural interference with the waterproof and breathable membrane 3 and the anti-radiation membrane 8 at both ends of the metal frame.

[0073] Optionally, in this embodiment, the inner keel 6 of the frame is made of a wooden keel or a wood-plastic keel, preferably a wooden keel.

[0074] Optionally, in this embodiment, a reserved groove 17 is integrally provided at one end surface of the metal frame, and an oblique support unit 18 is placed in the reserved groove 17 .

[0075] The fifth layer is constructed as a heat-insulating board 7 .

[0076] The insulation board 7 can be made of rock wool or the like, and is determined according to the actual grid size of the horizontal and vertical keels in the metal frame, filled into the empty space, and installed with an interference fit.

[0077] The sixth layer is constructed as a radiation protection film 8 .

[0078] The radiation protection film 8 can be attached to the inner side of the metal frame keel 4 using a special adhesive.

[0079] The seventh layer is constructed as an indoor keel frame 9.

[0080] The indoor keel frame 9 is a frame-and-keel structure, and can be a metal keel, a light steel keel, or a wood-plastic keel. This embodiment prefers a frame structure with only a single vertical keel, again for the purpose of both strengthening and reducing overall weight. This embodiment prefers using a wood-plastic keel. To enhance the strength of the indoor keel frame 9, indoor vertical keels 91 are installed within it. These can be single or multiple.

[0081] In this embodiment, the interior of the structural layers of the integrated lightweight exterior wall of the 7-layer structure and the structural layers are fixed together by self-tapping screws.

[0082] Construction in cold regions requires better thermal insulation. In the 7th layer of the indoor keel frame 9, the insulation board 7 is firmly embedded in each frame grid. Figure 8 shown.

[0083] Whether the exterior wall can form a stable support with the assembled steel structure is also a problem that needs to be considered and solved in the present invention.

[0084] Optionally, a reserved groove 17 is provided on the metal frame, and an oblique support unit 18 is placed in the reserved groove 17 and fixed or plugged into the metal frame to form a steel frame-support system, such as Figure 9 The purpose of providing the oblique support unit 18 is to form an integrated support system with the frame structure of steel beams and steel columns, thereby enhancing the overall strength of the prefabricated steel structure building.

[0085] Specifically, the technical solution of the steel frame-support system of the present invention is:

[0086] Two symmetrically intersecting through-reserved slots 17 are provided at one flat end of the metal frame structure. The reserved slots 17 extend through the metal frame keel 4 and the inner frame keel 6 and / or cross-bracing keel 5 disposed therein. If the metal frame keel 4 also includes a double-hugging C-shaped keel for reinforcement, the reserved slots 17 extend through the double-hugging C-shaped keel.

[0087] Optionally, the oblique support unit 18 is fixed to a metal frame, such as Figures 11-12 shown.

[0088] Specifically, the diagonal support unit 18 includes a first fixed diagonal support 20 and a second fixed diagonal support 21, which intersect inside the metal frame, with their ends extending out of the metal frame keel 4 and fixed to the metal frame keel 4 at the reserved groove 17 of the metal frame keel 4;

[0089] The extended ends of the first fixed oblique support 20 and the second fixed oblique support 21 are fitted into the steel column oblique support reserved groove 19 on the steel column 16 and are detachably fixed to the steel column 16 via anti-pullout connectors;

[0090] The first fixed oblique support 20 has a first fixed slot 201, and the second fixed oblique support 21 has a second fixed slot 211, wherein the first fixed slot 201 and the second fixed slot 211 have a matching card and structure. Specifically, the two are groove structures that match each other to ensure that after the first fixed oblique support 20 and the second fixed oblique support 21 are carded, the oblique support unit 18 is a structural member with consistent thickness.

[0091] Preferably, a cylindrical body is provided on the bottom surface of the first fixing notch 201, and a corresponding cylindrical hole is provided on the bottom surface of the second fixing notch 211. The two are clearance-matched to allow for adjustment of the angle between the first fixed diagonal support 20 and the second fixed diagonal support 21 to accommodate different metal frames and the steel structure frames to which they are mounted. In this case, the width of the first fixing notch 201 and the second fixing notch 211 should be equal to the width of each of the two support plates.

[0092] Preferably, a triangular prism is provided on the bottom surface of the first fixed slot 201, and correspondingly, a matching triangular prism is provided on the bottom surface of the second fixed slot 211, and the two are clearance-matched so that the first fixed oblique support 20 and the second fixed oblique support 21 can be positioned, and the contact area is increased, which is beneficial to enhancing the strength of the oblique support unit 18 itself.

[0093] When manufacturing a non-destructive, integrated lightweight exterior wall, the steps involved in fixing the diagonal support units 18 to the metal frame should be considered simultaneously with the manufacturing of the metal frame. The steps for fixing the diagonal support units 18 to the non-destructive, integrated lightweight exterior wall are as follows:

[0094] According to the steel frame structure, the reserved slot 17 and the steel column oblique support reserved slot 19 are designed;

[0095] A reserved groove 17 is provided for each relevant part (including the metal frame keel 4, the frame inner keel 6, and optionally, the cross bracing keel 5 and the double-hugging C-shaped keel); a steel column oblique support reserved groove 19 is provided on the steel column 16;

[0096] Making a metal frame except for the diagonal support unit 18;

[0097] Place the first fixed diagonal support 20 in a reserved groove 17 and fix both ends to the metal frame keel 4;

[0098] Place the second fixed diagonal support 21 in another reserved groove 17, and at the same time cross-place it with the first fixed diagonal support 20 through the engagement of the first fixed slot 201 and the second fixed slot 211. Optionally, fix them at the intersection; fix both ends of the second fixed diagonal support 21 to the metal frame keel 4.

[0099] Preferably, the oblique support unit 18 is movably connected to the metal frame, such as Figure 13 As shown. The oblique support unit 18 includes a first plug-in oblique support 22 and a second plug-in oblique support that can be limitedly inserted and removed in the reserved groove 17 of the metal frame; wherein, the second plug-in oblique support includes a second plug-in 1 support 23 and a second plug-in 2 support 24, which are arranged in a straight line due to the reserved groove 17, the first fixed oblique support 22 and their own limitation, forming a second plug-in oblique support. Specifically, a first plug-in slot 221 is provided in the middle of the first plug-in oblique support 22, specifically an open slot; on both sides of the first plug-in slot 221, a first plug-in slot adjustment unit 2211 is provided, specifically two concave arc surfaces located at the position where the second plug-in oblique support passes; correspondingly, the plugged-in ends of the second plug-in 1 support 23 and the second plug-in 2 support are respectively provided with a step structure to form their own installation slots, namely the second plug-in oblique support 1 slot 231 on the second plug-in 1 support 23, and the second plug-in oblique support 2 slot 241 on the second plug-in 1 support 24.

[0100] An inner arc surface and a matching outer arc surface are respectively provided at the upper steps of the two notches, serving as the second plug 1 supporting upper adjustment unit 233 and the second plug 2 supporting lower adjustment unit 243 .

[0101] Convex arc surfaces are respectively provided at the lower steps of the two slots as the second plug 1 support lower adjustment unit 232 and the second plug 2 support lower adjustment unit 242, which cooperate with the concave arc surfaces of the first plug slot adjustment unit 2211 from both sides.

[0102] The upper arcuate surface contact allows for slight adjustment of the positional relationship between the second plug-in support 1 23 and the second plug-in support 2 24 during installation, allowing for a straight line structure to form the second plug-in diagonal support. The lower arcuate surface contact allows for a certain range of adjustment of the angle between the second plug-in diagonal support 23 and the second plug-in support 24 and the first plug-in diagonal support 22 to accommodate steel frame structures of varying sizes. This double-layered arcuate surface design allows for these two position adjustments to occur independently of each other.

[0103] The steps for manufacturing the oblique support unit 18 that can be plugged and installed into the integrated lightweight exterior wall without damage and disassembly are as follows:

[0104] According to the design dimensions, make the first plug-in oblique support 22, the second plug-in 1 support 23 and the second plug-in 2 support 24;

[0105] A reserved groove 17 is provided for each relevant part (including the metal frame keel 4, the frame inner keel 6, and optionally, the cross bracing keel 5 and the double-hugging C-shaped keel); a steel column oblique support reserved groove 19 is provided on the steel column 16;

[0106] After the production of the integrated lightweight exterior wall is completed, first insert the first plug-in diagonal support 22 into the first reserved groove 17 from the first side of the integrated lightweight exterior wall, and the extended length of the end meets the relevant requirements;

[0107] The second plug-in 1 support 23 and the second plug-in 2 support 24 are respectively inserted into the second reserved groove 17 from the upper portion of the second side surface and the lower portion of the first side surface of the integrated lightweight exterior wall.

[0108] Regardless of which type of non-destructive integrated lightweight exterior wall is being fabricated and installed, the remaining steps for fabricating the integrated lightweight exterior wall remain unchanged. During installation, the extended ends of the diagonal bracing units 18 are first inserted into the steel column diagonal bracing slots 19 of the steel columns 16 and secured to form a compatible steel frame-support system.

[0109] Specifically, in this embodiment, when manufacturing the diagonal support unit 18, the horizontal bracing keel 5 within the metal frame keel 4 is eliminated, and the internal frame keel 6 is a single keel. Pre-set grooves 17 are provided on the metal frame keel 4 and the internal frame keel 6. Correspondingly, corresponding steel column diagonal support pre-set grooves 19 are pre-set on the steel column 16.

[0110] When installing the integrated lightweight exterior wall of the present invention, the protruding end of the diagonal support unit 18 placed in the reserved groove 17 can be pushed into the corresponding diagonal support reserved groove on the steel column 16. Through the anti-pullout connector and the steel column 16, the support of the integrated lightweight exterior wall and the frame support composed of steel beams and steel columns form a compatible steel frame-support system.

[0111] When the oblique support unit 18 is provided, the position of the oblique support unit 18 in the metal frame keel 4 avoids adding a double-embracing C-shaped keel 12. This is conducive to convenient processing of the reserved groove 17.

[0112] The internal structure of the integrated lightweight exterior wall only needs to match the form and depth of the grooves on the metal frame keel 4 and its internal structure, as well as the steel column 16 with the diagonal support unit 18.

[0113] Figure 10 A schematic diagram illustrates an integrated exterior wall panel structure with a steel frame-support system. As can be seen, reserved slots 17 are provided in the metal frame keels 4 and the inner frame keels 6, providing the necessary support. The diagonal bracing units 18, exposed from the integrated exterior wall panel, can be inserted into the reserved slots 19 for steel column diagonal bracing on the steel columns 16 and secured to them using pull-out connectors. Figure 10The insulation board 7 shown in the figure is a whole, cut insulation board selected according to the design drawing, which can be embedded in the metal frame keel 4 as a whole, avoiding the problem that the structure of the insulation board installed on the metal frame keel 4 is too scattered due to the coexistence of the inclined support unit 18 and the keel 6 in the frame, and the production of discrete insulation panels is too complicated.

[0114] Figure 9 and Figure 10 In the technical solution, the inclined support unit 18 does not need to be welded and fixed integrally with the steel beam and steel column 16. It only needs to be fastened with a pull-out connector when the integrated lightweight exterior wall that is non-destructively disassembled is installed integrally to the assembled steel structure, ensuring that the present invention can still be non-destructively disassembled under the steel frame-support system structure.

[0115] Since the non-destructive disassembly integrated lightweight exterior wall of the present invention is produced in parts, only a part is made into a wall with installable diagonal supports. The installation angle and size of the diagonal supports are kept uniform in the metal frame keel 4 integral component, the steel column 16 and the diagonal support unit 18.

[0116] The integrated lightweight exterior wall of the present invention can be produced in a chain factory. The structural layers are fast and efficient connected by self-tapping screws during assembly construction. The lightweight exterior wall is lightweight and is connected to the main structure of the building via bolts 13. This allows for rapid assembly and non-destructive disassembly at the construction site, reducing resource consumption during construction and use. The wall can be widely used in the construction of prefabricated steel structures, and is particularly suitable for the rapid construction of emergency rooms.

[0117] The following matters need to be explained during the design, production and installation of integrated lightweight exterior walls:

[0118] 1) The metal frame keel 4 in the metal frame of the integrated lightweight exterior wall structure is the key part for connecting the integrated lightweight exterior wall with the steel beams and steel columns 16 of the steel structure building body. The connection method is bolt connection 13, which can achieve rapid installation and non-destructive disassembly, and can be reused in different locations. Bolt holes are reserved at the corresponding positions on the metal frame keel, and operation holes for bolts 13 are reserved when necessary;

[0119] 2) The specifications and dimensions of the wall panels can be flexibly determined within a reasonable size range according to the size of the functional space;

[0120] 3) When the wall panels need to be reinforced due to functional requirements, C-type double-clamp keels (channel steel is recommended, and its specifications are determined by structural force calculations) can be used for local reinforcement at the corresponding locations;

[0121] 4) When there is a need to arrange doors, windows, and structural lateral force resisting components, the wall panels shall be reinforced with holes in accordance with the specifications;

[0122] 5) If Figure 7As shown, at the external corners, internal corners, and horizontal connection nodes of the wall panels, silicone glue 15 and polyethylene round rods 14 are used for waterproofing;

[0123] 6) If a steel frame-support system is to be formed by integrating a lightweight exterior wall with a steel frame structure, and diagonal bracing units 18 are required, avoid using both the horizontal bracing purlin 5 and the double-hugging C-shaped purlin 12 in the same location. Furthermore, since the diagonal bracing units 18 have a certain thickness, simply cross-connecting them with two diagonal bracing units 18 to form a steel column 16 is sufficient. Specifically, the thickness of the opposing surfaces at the intersection of the two diagonal bracing units 18 can be halved, so that the two diagonal bracing units 18 operate in the same plane.

[0124] The integrated lightweight exterior wall of the present invention has a reasonable design and is easy to manufacture and install. Figures 6-8 , the steps are as follows (the following steps take into account the installation of the optional double-hugging C-shaped keel 12 and the diagonal support unit 18):

[0125] S1: Component-based production of integrated lightweight exterior walls that can be disassembled without damage;

[0126] In order from the outside to the inside of the wall, the exterior wall panel 1, the connecting plate 2, the waterproof breathable membrane (3), the metal frame keel 4, the frame inner keel 6 and / or the cross-bracing keel 5, the insulation board 7, the radiation-proof membrane 8, and the interior keel frame 9 are fixed or filled in sequence; the specific steps are as follows:

[0127] Step 1) The connecting plate 2 is fixed to the exterior wall decorative panel 1 by self-tapping screws;

[0128] Step 2) Install a waterproof and breathable membrane 3 close to the exposed side of the connecting plate 2 to form an outer structural layer;

[0129] Step 3) Assemble the metal frame keel 4, the cross bracing keel 5, and the inner frame keel 6 to form an integral frame. Optionally, the double-hook C-shaped keel 12 may be fixed to the inner frame keel 6 and the metal frame keel 4. Alternatively, the diagonal support unit 18 may be fixed to the metal frame keel 4. It is important to avoid using these two options simultaneously.

[0130] Self-tapping screws are used for installation. In this embodiment, channel steel is preferably used for the metal frame keel 4, the cross-bracing keel 5 (and the double-hugging C-shaped keel 12). Its dimensions are determined by structural force calculations and the dimensions of the assembled steel structure frame. Blockboard or wood-plastic board is optional for the frame keel 6, with blockboard being preferred. Pull-out connectors are used to secure the diagonal support units 18 to the steel columns.

[0131] Step 4) Fill the insulation board 7 into the overall frame in step 3. It is recommended to use rock wool insulation material for the insulation board 7;

[0132] Step 5) Fix the outer structural layer in step 2 to the overall frame in step 3, with the waterproof and breathable membrane side close to the overall frame;

[0133] Step 6) Use a special adhesive to lay the radiation protection film 8 on the inner side of the structure completed in step 5;

[0134] Step 7) Use self-tapping screws to fix the double-hugging C-shaped keel 12 to the indoor keel frame 9 at the position of the double-hugging C-shaped keel 12 corresponding to step 3; or fix the diagonal support unit 18 to the indoor keel frame 9, and then fix the indoor keel frame 9 to the metal frame keel 4, the frame inner keel 6, and the radiation protection film 8 to form the final integral exterior wall;

[0135] S2: Push the non-destructively disassembled integrated lightweight exterior wall into the steel frame structure and secure it. Specifically, bolts 13 are used to secure the integrated lightweight exterior wall to the steel beams of the main building structure. Bolts 13 are then used to secure the integrated lightweight exterior wall to the steel columns 16 of the main building structure through the bolt installation holes 11.

[0136] S3: Continuously assemble the integrated lightweight exterior walls to complete the wall assembly of the main building structure;

[0137] S4: Fill the gaps around the integrated lightweight exterior walls with polyethylene rods 14, and then fill with silicone glue 15;

[0138] The method may further include the following steps: S5: removing the silicone adhesive 15 and the polyethylene round rod 14, removing the bolts 13, and removing the integrated lightweight exterior wall;

[0139] S6: Dismantle the integrated lightweight exterior walls of the individual units one by one and use them at a different location.

[0140] Furthermore, in practical applications, the integrated lightweight exterior walls of this invention are typically designed and installed in collaboration with various disciplines. Specifically, the wall design incorporates collaboration with the electromechanical engineering disciplines, meeting the current and future requirements for fully integrated design across all disciplines. Specifically, during design and fabrication, the interior panels are installed and secured to the interior keel frame only after the various equipment and piping systems have been laid within the wall, completing the entire wall assembly.

[0141] This method of laying pipelines inside walls is currently found in building partition walls, but is rarely seen in exterior walls. Other exterior walls are generally grooved on-site, which requires a lot of on-site work and increases the construction period and manpower.

[0142] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by any technician familiar with this technical field within the technical scope disclosed by the present invention should be covered by the scope of protection of the present invention.
