[0053] One of the core concepts of this utility model embodiment is to disclose a photovoltaic system that can be installed on the building keel 300 of a building. The photovoltaic system may include a photovoltaic module 200 and a mounting component 100. The mounting component 100 is connected between the photovoltaic module 200 and the building keel 300. As shown in Figures 1 to 3, the photovoltaic module 200 includes a frame 210, which has a frame body 212 and a rib 211 protruding from one side of the frame body 212 along a first direction. The mounting component 100 includes a first mounting member 110, which has a first mounting part 111 and a second mounting part 112 connected to each other.

The limiting plate 131 includes a first end and a second end opposite to each other along the second direction. The side of the first end away from the mounting plate 132 abuts against the side of the frame 212 away from the rib 211, and the second end protrudes from the mounting plate 132 and is engaged with the second mounting part 112; the second fastener 140 is fastened to the mounting plate 132 and the building keel 300 respectively.
[0054] In this embodiment of the invention, the first fastener 120 is fastened to the first mounting part 111 and the protruding rib 211 of the frame 210, respectively, thereby achieving the installation and fixation between the first mounting part 110 and the photovoltaic module 200. The second fastener 140 is fastened to the mounting plate 132 and the building keel 300, respectively, thereby achieving the installation and fixation between the second mounting part and the building. The second end of the limiting plate 131 can be engaged with the second mounting part 112 to achieve the installation and fixation between the first mounting part 110 and the second mounting part 130. This allows the photovoltaic module 200 to be installed on the building using the mounting assembly 100. The mounting assembly 100 can meet the installation requirements of the photovoltaic module 200 in different installation scenarios without requiring modification of the frame 210 of the photovoltaic module 200 or the addition of special connection holes according to the installation scenario. This reduces the waste of production resources and material resources, and improves construction efficiency.
[0055] The mounting component 100 described in this embodiment can be installed and fixed to both the photovoltaic module 200 and the building, thereby enabling the photovoltaic module 200 to be transferred to the building. Specifically, the building includes a building frame 300, and the mounting component 100 can be installed and fixed to the building via the building frame 300.
[0056] Specifically, as shown in Figure 1, the first direction S1 is the horizontal direction, and the second direction S2 is the vertical direction.
[0057] Specifically, the photovoltaic module 200 may include a laminate 220 and a frame 210. The laminate 220 can be made by connecting solar cells, encapsulation materials, and a glass cover into a whole through a lamination process. The laminate 220 is used to convert solar energy into electrical energy. The frame 210 may include a frame body 212 and a rib 211 protruding from one side of the frame body 212 along a first direction. The frame body 212 has a connecting groove that can engage with the edge of the laminate 220 to protect the edge of the laminate 220 and prevent problems such as breakage or cracking of the edge of the laminate 220. As shown in Figures 2 and 3, the rib 211 can be arranged opposite to and spaced apart from the laminate 220. The frame 210 has a frame A side 210a, a frame B side 210b, and a frame C side 210c.
[0058] Specifically, the mounting component 100 includes a first fastener 120 and a second fastener 140, both of which can be fastening bolts.
[0059] Furthermore, the first mounting part 111 of the first mounting component 110 can be assembled and snapped with the protruding rib 211 of the frame 210, and the first fastener 120 is fastened to the first mounting part 111 and the protruding rib 211 of the frame 210 respectively, so as to realize the installation and fixation between the first mounting component 110 and the photovoltaic module 200.
[0060] Specifically, the mounting plate 132 of the second mounting component 130 can be assembled with the building keel 300, and the second fastener 140 is connected to the mounting plate 132 and the building keel 300 respectively, so as to realize the installation and fixation between the second mounting component 130 and the building keel 300.
[0061] Specifically, the first mounting part 111 is engaged with the protruding rib 211, the second mounting part 112 is located below the frame 212, and the first end of the limiting plate 131 can abut against the side of the frame 212 away from the protruding rib 211. In this way, with the cooperation of the first mounting part 110 and the second mounting part 130, the frame 210 can be limited, which is beneficial to improving the reliability and stability of the frame 210 installation and fixation.
[0062] Furthermore, the second mounting part 112 can be engaged with the limiting plate 131 of the second mounting component 130, which helps to ensure the reliability and stability of the assembly between the first mounting component 110 and the second mounting component 130, thereby enabling the photovoltaic module 200 to be installed on the building through the mounting component 100.
[0063] Specifically, the limiting plate 131 can be arranged at an angle to the mounting plate 132, and the angle can be 90 degrees or close to 90 degrees, etc., which is not specifically limited in this embodiment of the present invention. The limiting plate 131 and the mounting plate 132 can be integrally formed to improve the structural stability of the second mounting member 130. In some optional embodiments, the limiting plate 131 and the mounting plate 132 can also be spliced and fixed.
[0064] In this embodiment of the utility model, for photovoltaic modules 200 of the same type, the frame 210 has the same structure and can be installed on the building by the mounting component 100. The mounting component 100 can be directly compatible with the same model of photovoltaic module 200 in various installation scenarios.
[0065] In some alternative embodiments, the first mounting part 111 includes a mounting plate 1111 and a fastening plate 1112. One end of the mounting plate 1111 is connected to the fastening plate 1112, and the other end of the mounting plate 1111 is connected to the second mounting part 112. The mounting plate 1111 and the fastening plate 1112 are arranged opposite to each other and spaced apart. A slot 1113 is formed between the mounting plate 1111 and the fastening plate 1112. The opening of the slot 1113 is opposite to the first end, and the slot 1113 is used to engage the protruding rib.
[0066] In this embodiment of the invention, the protruding rib can be pre-installed via the slot 1113 and then fastened using the first fastener 120, which improves the convenience and reliability of installing the photovoltaic module 200 and the first mounting part 110. Furthermore, the slot 1113's opening is opposite to the first end of the limiting plate 131, facilitating the first end's contact with the side of the frame 212 away from the protruding rib 211. This allows the limiting plate 131 to limit the frame 210, reducing the wind direction that could cause the frame 210 to detach, thereby improving the convenience of installing and fixing the photovoltaic module 200. Simultaneously, it ensures that the installation of the first mounting part 111 and the protruding rib 211, and the installation of the second mounting part 112 and the limiting plate 131, do not interfere with each other.
[0067] Specifically, the protruding rib 211 of the frame 210 can be inserted into the slot 1113, the C-side 210c of the frame can abut against the side of the mounting plate 1111 facing the fastening plate 1112, and the mounting plate 1111 can also support the frame 210. The first end of the limiting plate 131 can abut against the B-side 210b of the frame to limit the protruding rib 211 in the slot 1113.
[0068] In some optional embodiments, as shown in FIG5, the first mounting part 111 further includes an adapter plate 1114. The mounting plate 1111, the adapter plate 1114 and the fastening plate 1112 are connected in sequence. The adapter plate 1114 intersects with the mounting plate 1111 and the fastening plate 1112 respectively. The mounting plate 1111 and the fastening plate 1112 are connected through the adapter plate 1114.
[0069] In this embodiment of the utility model, the mounting plate 1111 and the fastening plate 1112 can be connected as one piece by the adapter plate 1114, so that the first mounting part 111 can be a one-piece molded structure, which is beneficial to ensuring the structural stability of the first mounting part 111.
[0070] In some alternative embodiments, a first snap-fit member 1115 is provided on the assembly plate 1111, and a second snap-fit member 1116 is provided on the fastening plate 1112, and the first snap-fit member 1115 and the second snap-fit member 1116 are snapped together.
[0071] In this embodiment of the utility model, the assembly plate 1111 and the fastening plate 1112 can be fastened together by a snap-fit component to ensure the reliability of the connection between the assembly plate 1111 and the fastening plate 1112, thereby ensuring the stability of the frame 210 by the snap-fit slot 1113.
[0072] In some alternative embodiments, the first snap-fit member 1115 includes a first protrusion, a vertical portion, and a horizontal portion. The first protrusion and the vertical portion are connected to the side of the mounting plate 1111 facing the fastening plate 1112. The first protrusion and the vertical portion are arranged opposite to each other and spaced apart along a first direction. The horizontal portion is connected to the end of the vertical portion away from the mounting plate 1111. The horizontal portion extends along the first direction and is opposite to and spaced apart from the mounting plate 1111 along a second direction. At the same time, the horizontal portion and the first protrusion are spaced apart along the second direction. The second snap-fit member 1116 includes a second protrusion. The second protrusion is connected to the side of the fastening plate 1112 facing the mounting plate 1111. The second protrusion is snapped between the first protrusion and the vertical portion, and the side of the fastening plate 1112 away from the mounting plate 1111 abuts against the horizontal portion.
[0073] In this embodiment, the first protrusion and the vertical portion can limit the first protrusion from the first direction, and the horizontal portion and the mounting plate 1111 can limit the first protrusion from the second direction, thereby achieving the snap-fit stability of the first snap-fit member 1115 and the second snap-fit member 1116.
[0074] Specifically, the mounting plate 1111 may also be provided with a groove opposite to the second protrusion, with at least a portion of the second protrusion embedded in the groove. This can further improve the stability of the engagement between the first snap-fit member 1115 and the second snap-fit member 1116, as shown in Figures 4 and 7. The first snap-fit member 1115 is a C-shaped snap-fit, and the second snap-fit member 1116 is a U-shaped snap-fit. Alternatively, the first snap-fit member 1115 can be a C-shaped snap-fit, and the second snap-fit member 1116 can be an L-shaped snap-fit. In this embodiment, since the horizontal part and the nut of the first fastener 120 are located on different sides, interference between the horizontal part and the nut of the first fastener 120 can be avoided.
[0075] In some other embodiments, the shapes of the first snap-fit member 1115 and the second snap-fit member 1116 can be interchanged, that is, the first snap-fit member 1115 is a U-shaped snap-fit and the second snap-fit member 1116 is a C-shaped snap-fit. Alternatively, the first snap-fit member 1115 can be an L-shaped snap-fit and the second snap-fit member 1116 can be a C-shaped snap-fit, so that the first snap-fit member 1115 and the second snap-fit member 1116 are correspondingly set and structurally compatible.
[0076] In some alternative embodiments, as shown in FIG6, the assembly plate 1111 includes a reinforcing part 11111 and a non-reinforcing part, the thickness ratio of the reinforcing part 11111 to the non-reinforcing part is X, 1 < X ≤ 5; a first fastener 120 is sequentially inserted through the reinforcing part 11111, the rib 211 and the fastening plate 1112 along the second direction, the first fastener 120 is threadedly connected to the fastening plate 1112, and the nut of the first fastener 120 is located on the side of the assembly plate 1111 away from the fastening plate 1112.
[0077] In this embodiment, the reinforcing part 11111 is thicker and has stronger structural strength. The mounting plate 1111 can be fastened to the first fastener 120 via the reinforcing part 11111, effectively ensuring the reliability and firmness of the fastening fit between the mounting plate 1111 and the first fastener 120. The first fastener 120 is threadedly connected to the snap-fit plate 1112, and the nut of the first fastener 120 is located on the side of the mounting plate 1111 away from the snap-fit plate 1112, facilitating tightening of the first fastener 120 and achieving locking between the first fastener 120 and the limiting plate 131, thus ensuring the reliability of the fastening connection between the first mounting part 111 and the frame 210.
[0078] Specifically, the thickness of the reinforcing part 11111 is greater than the thickness of the non-reinforcing part. This can be achieved by locally thickening the mounting plate 1111 to enhance the reliability of the fastening fit between the mounting plate 1111 and the first fastener 120. The thickness ratio of the reinforcing part 11111 to the non-reinforcing part is X, where 1 < X ≤ 5. For example, the value of X can be 1.1, 1.2, 1.4, 1.6, 1.8, 2, 2.2, 2.4, 2.6, 2.8, 3, 3.2, 3.4, 3.6, 3.8, 4, 4.2, 4.4, 4.6, 4.8, or 5, etc.

[0080] In this embodiment of the present invention, the nut of the first fastener 120 is located on the side of the mounting plate 1111 away from the fastening plate 1112, which facilitates the observation of the alignment of the first through hole and the first threaded hole, and thus facilitates the use of the first fastener 120 for fastening.
[0081] Specifically, the rib 211 may have a first mounting hole, which may be a through hole or a threaded hole, and may be a round hole or an elongated hole. During installation, the rib 211 may be first secured in the slot 1113, and then the first fastener 120 may be passed through the first through hole and the first mounting hole in sequence, and then screwed into the first threaded hole.

[0085] Specifically, a second mounting hole can be provided on the building keel 300. During installation, the second through hole, the second mounting hole and the second threaded hole can be aligned first, and then the second fastener 140 can be passed through the second through hole and the second mounting hole in sequence, and then screwed into the second threaded hole.
[0086] In some alternative embodiments, the second mounting part 112 includes a clamping plate 1121, one end of which is connected to the first mounting part 111, and the other end of which is provided with a boss 1122. The boss 1122 protrudes from the side of the clamping plate 1121 facing the frame 212 and is engaged with the second end; the side of the clamping plate 1121 away from the frame 212 can abut against the building keel 300.
[0087] In this embodiment of the utility model, one side of the limiting plate 131 is engaged with the boss 1122, and the other side can abut against the side of the frame 212 away from the rib 211. In this way, while ensuring reliable assembly between the second mounting part 130 and the first mounting part 110, the limiting plate 131 can also limit the frame 210, thereby improving the reliability of the frame 210 installation and fixation.
[0088] Specifically, the side of the clamping plate 1121 facing away from the frame 212 abuts against the building keel 300, which facilitates the pre-installation of the second mounting piece 130 to the building keel 300 through the first mounting piece 110, and then fastening it with the second fastener 140, which can improve the convenience of installing and fixing the mounting plate 132 and the building keel 300.
[0089] Specifically, the second end of the limiting plate 131 can be engaged with the boss 1122. The limiting plate 131 can be engaged inside the boss 1122, and the boss 1122 can be engaged inside the limiting plate 131. The limiting plate 131 and the boss 1122 can restrain each other.
[0090] Specifically, the boss 1122 protrudes from the clamping plate 1121 in the second direction by a height of h1. If h1 is too small, it is easy to fail to hold the limiting plate 131, causing the second mounting member 130 to detach from the first mounting member 110. Therefore, in this embodiment of the utility model, h1 is controlled to be ≥1mm so that the boss 1122 has a certain height so as to effectively hold the limiting plate 131.
[0091] In some optional embodiments, 1mm≤h1≤20mm can control the protrusion height of the boss 1122 to not be too large, so as to avoid interfering with the installation fit between the limiting plate 131 and the first mounting part 111.
[0092] For example, the height h1 of the boss 1122 protruding from the clamping plate 1121 in the second direction can be 1mm, 5mm, 8mm, 10mm, 12mm, 15mm, 18mm, 20mm, etc.
[0093] Optionally, the second end protrudes from one side of the mounting plate 132 along the second direction, which can effectively ensure the reliability of the snap-fit between the limiting plate 131 and the boss 1122. The height of the second end protruding from the mounting plate 132 along the second direction is h2. If h2 differs too much from h1, it is easy for the boss 1122 to fail to hold the limiting plate 131, causing the second mounting part 130 to detach from the first mounting part 110. Therefore, in this embodiment of the present invention, 0≤h2-h1≤5mm is controlled to avoid the boss 1122 and the limiting plate 131 from detaching from each other, and to ensure the reliability of the assembly between the first mounting part 110 and the second mounting part 130.
[0094] For example, h2-h1 can be equal to 0, 0.8mm, 1.2mm, 2mm, 3mm, 4.2mm, 5mm, etc.
[0095] Specifically, the clamping plate 1121 can be arranged parallel to or nearly parallel to the assembly plate 1111.
[0096] In some alternative embodiments, the clamping plate 1121 can be flush with the assembly plate 1111, so that the clamping plate 1121 and the assembly plate 1111 can be on the same plane. The first fastener 120 can be a countersunk bolt, or the building keel 300 can be provided with a relief portion to avoid the nut of the first fastener 120.
[0097] In some alternative embodiments, the first mounting member 110 further includes a first connecting plate 113, one end of which is connected to the first mounting part 111, and the other end of which is connected to the clamping plate 1121; the first connecting plate 113 intersects with the clamping plate 1121, and at least a portion of the first connecting plate 113 is disposed opposite to the boss 1122.
[0098] In this embodiment of the utility model, the first connecting plate 113 intersects with the clamping plate 1121 and is at least partially opposite to the boss 1122. Thus, under the action of the first connecting plate 113, there can be a height difference between the first mounting part 111 and the clamping plate 1121, which facilitates the first fastener 120 to avoid installation space and improves the convenience of fastening the first fastener 120 to the first mounting part 111.
[0099] Specifically, as shown in Figure 1, the side of the clamping plate 1121 away from the boss 1122 abuts against the building keel 300. By setting the first connecting plate 113, a height difference is formed between the first mounting part 111 and the clamping plate 1121, which facilitates avoiding the first fastener 120.
[0100] Specifically, the first connecting plate 113 can be perpendicular to the clamping plate 1121, or the included angle between the first connecting plate 113 and the clamping plate 1121 can be an obtuse angle or an acute angle, etc., and this embodiment of the present invention does not make specific limitations on this.
[0101] Specifically, when the first connecting plate 113 is perpendicular to the clamping plate 1121, the height of the first connecting plate 113 in the second direction determines the height of the installation space in the second direction. Taking the first connecting plate 113 being perpendicular to the clamping plate 1121 as an example, the height range of the first connecting plate 113 in the second direction can be 0-60mm. For example, when the height of the first connecting plate 113 in the second direction is 0, the clamping plate 1121 and the assembly plate 1111 are located on the same plane. When the height of the first connecting plate 113 in the second direction is 10mm, 15mm, 22mm, 30mm, 50mm, or 60mm, the assembly plate 1111 can be higher than the clamping plate 1121.
[0102] Specifically, the height of the first connecting plate 113 in the second direction can be adaptively adjusted according to factors such as the installation space requirements of the first fastener 120, the installation distance required between the photovoltaic module 200 and the building keel 300, or the stress range borne by the rib 211 of the frame 210. In this embodiment of the present invention, no specific limitation is made in this regard.
[0103] Optionally, as shown in FIG8, the distance between the end of the first mounting part 111 facing the limiting plate 131 and the boss 1122 in the first direction is a, the thickness of the limiting plate 131 is b, and the distance between the side of the frame 212 away from the rib 211 and the boss 1122 in the first direction is c, c≤a, which can avoid the first mounting part 111 interfering with the limiting plate limiting the frame 212.
[0104] Optionally, 0.5mm≤cb≤5mm can improve the reliability of the second end of the limiting plate 131 being inserted into the inner side of the boss 1122, thereby improving the reliability of the assembly between the first mounting member 110 and the second mounting member 130.
[0105] For example, cb can be equal to 0.5mm, 0.6mm, 1.8mm, 2.4mm, 3mm, 4mm, 4.8mm or 5mm, etc.
[0106] In some optional embodiments, as shown in FIG8, the first mounting component 110 further includes a second connecting plate 114. The second connecting plate 114 is connected to the connection between the mounting plate 1111 and the first connecting plate 113 and is flush with the mounting plate 1111. The second connecting plate 114 is disposed opposite to the clamping plate 1121. The second connecting plate 114 and the boss 1122 are respectively located on opposite sides of the limiting plate 131. The second connecting plate 114 is used to support the bottom of the frame 210 to improve the reliability of the frame 210 installation and fixation.
[0107] Specifically, the distance between the end of the second connecting plate 114 away from the mounting plate 1111 and the boss 1122 in the first direction is 'a'. Since a ≤ c, during installation, the end of the second connecting plate 114 away from the mounting plate 1111 does not exceed the B-side 210b of the frame, so as to effectively ensure that the limiting plate 131 can abut against the B-side 210b of the frame, so that the limiting plate 131 can play a limiting role on the frame 210.
[0108] Optionally, the portion of the first end that abuts against the side of the frame 212 away from the rib 211 has a height of h3 in the second direction. In this way, when installing the photovoltaic module 200, the first end of the limiting plate 131 can abut against the side B 210b of the frame 210 to limit the frame 210 and enhance the reliability of the installation and fixing of the photovoltaic module 200.
[0109] Specifically, when h3 is less than 3mm, the height of the first end limiting the frame 212 is too small, which is not conducive to the limiting plate 131 limiting the frame 210. When h3 is greater than 30mm, the height of the first end limiting the frame 212 is too large, making it easy for the limiting plate 131 to exceed the height of the frame 212, causing the limiting plate 131 to protrude from the A-side 210a of the frame, which can easily affect the aesthetics of the photovoltaic module 200. Therefore, in this embodiment of the present invention, by controlling 3mm≤h3≤30mm, both the limiting function of the limiting plate 131 on the frame 210 and the aesthetics of the photovoltaic module 200 can be achieved.
[0110] For example, h3 can be 3mm, 8mm, 10mm, 13mm, 20mm, 25mm, 26mm, or 30mm, etc.
[0111] In some alternative embodiments, as shown in FIG9, a stacking groove 11211 is provided on the side of the clamping plate 1121 away from the boss 1122. In this way, when the photovoltaic modules 200 are stacked, the top of the frame 210 of the lower photovoltaic module 200 can be embedded in the stacking groove 11211 of the clamping plate 1121 to which the upper photovoltaic module 200 is connected.
[0112] Specifically, the first mounting component 110 and the photovoltaic module 200 can be installed and fixed as a whole using the first fastener. The whole assembly is then stacked and transported to the building site, and then the whole assembly is installed and fixed to the building keel 300 using the second mounting component 130. As shown in Figure 9, during stacking, the top of the frame 210 in the lower assembly can be embedded in the stacking groove 11211 of the clamping plate 1121 in the upper assembly, that is, the frame A side 210a of the frame 210 in the lower assembly can abut against the bottom of the stacking groove 11211 in the upper assembly.
[0113] In other cases, the photovoltaic modules and the mounting components can be transported to the building site separately. Then, the first mounting component and the photovoltaic module are assembled into a whole using the first fastener. The whole assembly is then placed on the building keel, and the second mounting component is used to install and fix it to the first mounting component. Finally, the second fastener is used to secure the mounting plate and the building keel.
[0114] Specifically, the stacking groove 11211 can be formed by a plane. For example, the stacking groove 11211 can be an L-shaped groove, a U-shaped groove, or a rectangular groove. The stacking groove 11211 can also be formed by a curved surface, so that the stacking groove 11211 can be an arc-shaped groove.
[0115] In some alternative embodiments, the second mounting member 130 includes two limiting plates 131, which are symmetrically arranged on opposite sides of the mounting plate 132 in the second direction; the number of first mounting members 110 includes two, which are symmetrically arranged on opposite sides of the mounting plate 132 in the second direction, and the first mounting members 110 cooperate with the limiting plates 131 adjacent to them.
[0116] In this embodiment of the utility model, two first mounting members 110 can be installed and fixed to the frame 210 of two adjacent photovoltaic modules 200 respectively. Then, the two limiting plates 131 of a second mounting member 130 can be installed and fixed to the two first mounting members 110 respectively. In this way, two adjacent photovoltaic modules 200 can be installed and fixed to the building keel 300 at the same time through the mounting assembly 100, which can save installation parts and reduce costs.
[0117] Specifically, the two limiting plates 131 and the mounting plate 132 can be enclosed to form a U-shaped space, which can be used to accommodate the nut of the second fastener 140.
[0118] Specifically, as shown in Figure 10, two adjacent photovoltaic modules 200 can be installed and fixed using at least two mounting components 100. Further, as shown in Figure 11, sealant 400 can be filled into the gap between the frame B-side 210b of two adjacent photovoltaic modules 200, or foam rods and sealant 400 can be filled into the gap between the frame B-side 210b of two adjacent photovoltaic modules 200 to further enhance the reliability and stability of installing the photovoltaic modules 200 onto the building keel 300.
[0119] Optionally, the width L of the second mounting component 130 can be between 19mm and 50mm, specifically 19mm, 22mm, 25mm, 30mm, 40mm, 45mm, or 50mm, etc.
[0120] Specifically, the width L of the second mounting member 130 is the vertical distance between the outer edges of the two limiting plates 131. Since the limiting plate 131 abuts against the B-side 210b of the frame 210, the width L of the second mounting member 130 is the same as the gap size between the B-side 210b of the frames of two adjacent photovoltaic modules 200.
[0121] The mounting assembly described in this embodiment of the present invention has at least the following advantages:
[0122] In this embodiment of the invention, the first fastener is securely connected to both the first mounting portion and the frame, thereby securing the first mounting component to the photovoltaic module. The second fastener is securely connected to both the mounting plate and the building keel, thereby securing the second mounting component to the building. The second end of the limiting plate can engage with the second mounting portion, securing the first and second mounting components. This allows the photovoltaic module to be installed onto the building using the mounting assembly, which can meet the installation requirements of the photovoltaic module in different installation scenarios without requiring modifications to the frame of the photovoltaic module or the addition of dedicated connection holes, thus reducing waste of production resources and material consumption, and improving construction efficiency.
