[0069] The sequence of steps b21 and b22 is not distinguished, and the sequence is determined according to the non-interference in the installation process and high efficiency, which is not described herein again.

[0070] In this embodiment, in step a1, the scanning is completed by using a laser scanning device, a 3D laser scanning device has the functions of three-dimensional scanning and quickly acquiring parameters, and provides accurate theoretical guidance for the later construction;

[0071] The additional purlins include support purlins 2 for supporting the daylighting panels and raised purlins 3 for forming a layered and stacked arrangement of adjacent daylighting panels in the weft direction; the support purlins 2 are longitudinally arranged and at least two, even more, are arranged corresponding to one daylighting panel in the weft direction to ensure the stability of the support; the raised purlins 3 are arranged at the position close to the end (the lowest end) of the daylighting panel in the longitudinal direction, are raised relative to the support purlins 2 of the next level of daylighting panels in the weft direction, and are generally arranged near the joint between the adjacent daylighting panels in the longitudinal direction, and the length of 100 mm across the joint can ensure that the overall weight of the additional purlins is not excessively increased; of course, the raised purlins 3 can also be longitudinally arranged (such as Figure 2 The support purlins 2 are longitudinally arranged and at least two, even more, are arranged corresponding to one daylighting panel in the weft direction to ensure the stability of the support; the raised purlins 3 are arranged at the position close to the end (the lowest end) of the daylighting panel in the longitudinal direction, are raised relative to the support purlins 2 of the next level of daylighting panels in the weft direction, and are generally arranged near the joint between the adjacent daylighting panels in the longitudinal direction, and the length of 100 mm across the joint can ensure that the overall weight of the additional purlins is not excessively increased; of course, the raised purlins 3 can also be longitudinally arranged (such as

[0072] The support purlins 2 are longitudinally arranged and at least two, even more, are arranged corresponding to one daylighting panel in the weft direction to ensure the stability of the support; the raised purlins 3 are arranged at the position close to the end (the lowest end) of the daylighting panel in the longitudinal direction, are raised relative to the support purlins 2 of the next level of daylighting panels in the weft direction, and are generally arranged near the joint between the adjacent daylighting panels in the longitudinal direction, and the length of 100 mm across the joint can ensure that the overall weight of the additional purlins is not excessively increased; of course, the raised purlins 3 can also be longitudinally arranged (such as

[0073] In step a32, the light collecting plate is divided into several areas symmetrically to both sides with the spherical meridional center as the axis of symmetry, each area is equipped with a certain number of non-standard light collecting plates and a certain number of standard light collecting plates to adapt to the shape of the non-closed curved steel shed; in actual construction, the areas are symmetrically divided left and right, and the width of each area is controlled at 15m, each area is controlled by two non-standard light collecting plates and multiple (a variable) standard light collecting plates, and the separation line between the areas is determined as the center line of the non-standard light collecting plate; the center line a of the non-standard light collecting plate is used as the reference control line of each area to arrange the number of standard light collecting plates, the length of the standard light collecting plate is the maximum length (in the latitudinal direction) that can be reached by the existing manufacturing method and transportation capacity, according to the remaining size of each area after the standard plate is installed, the non-standard light collecting plate is formed by cutting the standard light collecting plate on site, generally only one side is cut, the other side is the same as the standard light collecting plate, which is beneficial to splicing and fixing with the standard light collecting plate; in construction, the cross section of the cut light collecting plate (hollow plate in this embodiment) needs to be treated, such as sealing the edge with aluminum foil tape and other sealing materials;

[0074] That is, in step b22, the light collecting plate is installed according to the model of step a32 in the meridional direction, the standard connecting device 6 is used to seal and splice between adjacent standard light collecting plates 4, and the non-standard connecting device 7 is used to seal and splice between adjacent non-standard light collecting plates; of course, since the non-standard light collecting plate 5 is obtained by cutting one long side of the standard light collecting plate, the other long side is the same as the standard light collecting plate, therefore, the standard connecting device 6 is used to seal and splice between the standard light collecting plate and the adjacent non-standard light collecting plate, which will not be described here; the standard connecting device 6 and the non-standard connecting device 7 refer to mechanical structures that can horizontally seal and connect standard light collecting plates and non-standard light collecting plates, such as the usual upper and lower sealing and pressing structures, which will not be described here.

[0075] In this embodiment, the standard connecting device 6 includes a standard base 601 and a standard pressing component 602. The standard base 601 is fixed to an additional purlin (which may be a supporting purlin 2 or a raising purlin 3, depending on the installation position), and is fixedly connected upwards to the standard pressing component 602 to press and seal two adjacent standard daylighting panels 4 in the warp direction. Since the standard daylighting panels are spliced ​​together in the warp (lateral) direction, the standard base 601 and the standard pressing component 602 should be strip-shaped structures in the weft direction, and their lengths should correspond to the warp lengths of the standard daylighting panels 4 (where the standard base 601 is the standard pressing component 602). The base 601 can be segmented along its length, for example, each additional purlin corresponds to one segment, which can reduce weight and save materials. However, a continuous setting corresponding to the standard lighting panel facilitates installation and alignment. This embodiment adopts a continuous setting. The standard pressing component 602 and the standard base 601 are located above and below the standard lighting panel 4 respectively and form a sealed pressing. That is, the standard pressing component 602 and the standard base 601 overlap and press the adjacent standard lighting panels 4 in the radial direction to complete the splicing of the adjacent standard lighting panels in the radial direction. This can be achieved by using a mechanical structure that can form a pressing and seal.

[0076] In the embodiment, the standard lighting panel 4 comprises a panel body and a bent edge 401 bent upward on both sides in the transverse direction; the cross section of the standard base 601 is approximately an I-shaped base, the upper flange 6011 of the I-shaped base is pressed on the bent edge 401 of the adjacent standard lighting panel 4 in the longitudinal direction, and the lower flange 6013 of the I-shaped base is fixed to the corresponding additional purlin (which can be the supporting purlin 2 or the elevated purlin 3, and the corresponding connection is selected according to the installation position), as shown in the drawings, the web 6012 of the I-shaped base penetrates upward between the bent edges of the two adjacent standard lighting panels 4 in the longitudinal direction, and the upper flange 6011 is pressed on the corresponding bent edge 401 on both sides in the transverse direction, forming a completed pressing structure, which has good integrity and is beneficial to improve the connection strength of the lighting panel; approximately I-shaped means that the cross section is approximately I-shaped, which can be a symmetrical I-shaped structure or an asymmetrical I-shaped structure, and details are not described herein; the standard pressing member cover is fixedly connected to the upper flange 6011 of the I-shaped base, and the transverse two sides of the standard pressing member 602 form downward standard pressing member side portions 6021, thereby forming two standard pressing member side portions 6021 on both sides in the transverse direction, as shown in the drawings, the two standard pressing member side portions 6021 are integrally formed on the transverse two ends of the standard pressing member and extend downward, straddling the two sides of the web 6012 of the I-shaped base; the lower end of each of the two standard pressing member side portions 6021 forms a foot portion, which forms an inward extending portion 6022 extending inward and an outward extending portion 6023 extending outward, where inward and outward refer to inward and outward in the transverse direction of the standard pressing member, inward refers to the direction of the web of the I-shaped base, and outward refers to the direction away from the web of the I-shaped base, and details are not described herein; the inward extending portion 6022 is pressed on the root outer side 4011 of the corresponding bent edge 401 of the standard lighting panel 4, as shown in the drawings, the root outer side 4011 (referring to the transverse outer side, which is consistent with the aforementioned inward and outward directions) of the bent edge 401 of the standard lighting panel 4 is a smooth transition curved surface, and the end of the inward extending portion 6022 also forms a pressing curved surface, after the standard pressing member 602 is fixed to the I-shaped base, the inward extending portion 6022 is pressed on the root outer side 4011 of the bent edge 401, which ensures the pressing strength and prolongs the overall service life;

[0077] In order to ensure that the pressing does not form uneven stress, a flexible layer 607 is provided between the inner extension 6022 and the root outer side 4011, and a sealing material such as aluminum foil tape is generally used during construction, which can ensure the pressing strength while avoiding the problem of cracking, and also ensures the sealing effect and compaction effect; as shown in the figure, an integral aluminum foil tape is horizontally arranged on the folded edge 401 of two adjacent standard lighting panels 4 in the warp direction and extends to the root outer side 4011 of the edge, which has good integrity and has a pulling and fixing effect on the adjacent standard lighting panel, which is beneficial to improve the overall strength; the outer extension 6023 is sealed and installed with a standard sealing strip 606 which is in close contact with the standard lighting panel 4, as shown in the figure, the outer extension 6023 is provided with a standard sealing groove in the longitudinal direction, the standard sealing groove is a tapered opening groove, the standard sealing strip 606 is made of a material with a certain elasticity (such as the ternary ethylene-propylene sealing rubber strip used in this embodiment), the upper part is provided with an expansion head 6061 which is embedded in the standard sealing groove through the expansion head 6061, and the lower part is a sealing lip, the sealing lip includes an inclined bar 6062 extending outward and downward and a protruding sealing part 6063 located inward of the inclined bar and protruding downward, the protruding sealing part 6063 has a downward arc surface which is in elastic contact with the surface of the standard lighting panel 4, forming a double sealing, the inclined bar faces the direction of incoming water and has a self-tight sealing effect under the pressure of water, combined with the elastic contact sealing arc surface, further ensuring the sealing effect; as shown in the figure, the upper part of the inclined bar 6062 extends upward to form a cover bar which closes the outer end of the outer extension 6023, avoiding water entering the standard sealing groove; the protruding sealing part 6063 is a hollow structure, which has better elastic contact sealing performance while saving production materials;

[0078] In order to ensure the aesthetic appearance and the sealing property of the top part, a strip-shaped buckle 603 is further buckled on the upper part of the standard pressing member 602, as shown in the figure, the transverse sides of the strip-shaped buckle 603 are smoothly bent downward and form inward protrusions, the transverse sides of the standard pressing member near the top part are provided with grooves, and the protrusions are embedded in the grooves with a certain pre-tightening force, so that the strip-shaped buckle is buckled on the standard pressing member.

[0079] In this embodiment, the root of the folded edge 401 of the standard lighting panel 4 is provided with a concave groove-shaped surface with smooth transition, and the end of the inner side extension 6022 is provided with a smooth curved surface which is adapted to the concave groove-shaped surface and is pressed together; as described above, the end of the inner side extension is provided with a curved surface structure which is adapted to the concave groove-shaped surface, so as to increase the pressing contact area and ensure the pressing strength; as shown in the drawings, the end of the inner side extension is integrally formed with an arc-shaped plate-shaped pressing head 60221, and the pressing curved surface is formed on the convex arc surface of the arc-shaped plate-shaped pressing head 60221. The transverse width of the arc-shaped plate-shaped pressing head is greater than the connection between the inner side extension 6022 and the arc-shaped plate-shaped pressing head 60221, so that the transverse sides of the arc-shaped plate-shaped pressing head have a certain deformation ability when the arc-shaped plate-shaped pressing head is pressed towards the root of the folded edge, thereby having good adaptability and being beneficial to ensuring the stability of the pressing.

[0080] The edge 6021 of the standard pressing member 602 and the top are fixed by the reinforcing rib plate 6024 which is integrally formed with the edge 6021 and the top. As shown in the drawings, the reinforcing rib plate 6024 and the edge 6021 and the top of the standard pressing member 602 form a strip-shaped cavity. The reinforcing rib plate itself has a good reinforcing effect, and the structure of the strip-shaped cavity greatly increases the effect of the standard pressing member resisting bending moment, thereby improving the overall connection and pressing strength and ensuring the connection strength and sealing effect of the standard lighting panel.

[0081] The upper flange 6011 of the I-shaped base 601 is connected to the web 6012 of the I-shaped base 601 through the expansion part 60121. The two sides of the expansion part 60121 are respectively abutted against the folded edges 401 of the adjacent standard lighting panels 4. As shown in the drawings, the folded edges 401 are provided with recesses which are adapted to the expansion part. The adaptation refers to the shape adaptation, which will not be described herein. The expansion part is a hollow tubular structure. As shown in the drawings, the cross section of the expansion part 60121 of this embodiment is rectangular, and the web 6012 of the I-shaped base is expanded transversely at the position close to the upper flange 6011 and integrally formed with the upper flange (of course, other shapes such as inverted triangular shape are also possible). The hollow tubular structure is beneficial to improving the ability of the web to resist bending moment without increasing the overall weight. As shown in the drawings, the standard pressing member 602 is fixedly connected to the upper flange 6011 of the I-shaped base by the screw 604. Due to the existence of the expansion part, the bending resistance of the upper flange 6011 is greatly increased, thereby ensuring the connection strength of the standard pressing member and the I-shaped base.

[0082] The upper surface of the lower flange 6013 of the I-shaped base is flat for supporting the standard lighting panel 4. One side of the lower flange 6013 is formed with a lower concave mounting groove 60131. The mounting groove 60131 is provided with a mounting screw 605 for fixing the lower flange 6013 to the additional purlin. The mounting groove 60131 is arranged to allow the mounting screw to be embedded in the mounting groove 60131, so as not to affect the flatness of the upper surface of the lower flange 6013, and to facilitate the support of the standard lighting panel 4. As shown in the drawings, the bottom of the lower flange 6013 is formed with a lengthwise buffer through groove 60132. The buffer through groove 60132 is arranged to avoid the mounting groove. The buffer through groove is a rectangular groove with a rectangular cross section. Since one side (bounded by the web) of the lower flange 6013 of the I-shaped base is fixed to the additional purlin, and the other side is directly placed on the additional purlin, the overall deformation adaptability of the I-shaped base is improved. In addition, the buffer through groove 60132 improves the buffer capacity of the support structure and further improves the deformation adaptability. The support structure has strong adaptability to the deformation of the standard lighting panel 4, and has good overall performance with the lighting panel and the additional purlin. Therefore, the lighting panel has high stability and long service life.

[0083] In the embodiment, the non-standard connecting device 7 includes a non-standard base 701 and a non-standard pressing member 702. The non-standard base 701 is fixed to the additional purlin (which can be a support purlin or a raised purlin according to different positions), and is fixedly connected to the non-standard pressing member 702 upward to press and seal the two non-standard lighting panels 5 adjacent in the warp direction. Since the non-standard lighting panels 5 adjacent in the warp direction are spliced, the non-standard base 701 and the non-standard pressing member 702 should be strip structures in the weft direction, and the length corresponds to the length of the non-standard lighting panel in the warp direction. The non-standard pressing member 702 and the non-standard base 701 are located above and below the non-standard lighting panel 5 respectively and form a sealed press. That is, the non-standard pressing member and the non-standard base are overlapped and pressed in the warp direction to splice the non-standard lighting panels adjacent in the warp direction. Any mechanical structure that can form a press and can be sealed can be used.

[0084] In this embodiment, the connecting part between adjacent non-standard lighting panels 5 is a flat plate structure; the cross section of the non-standard base 701 is a T-shaped base with inverted T shape, the wing plate 7011 of the T-shaped base is fixed to the additional purlin, and the non-standard lighting panel 5 is supported downward on the wing plate 7011 of the T-shaped base 701; the non-standard pressing member 702 is fixed and connected downward on the web of the T-shaped base across two adjacent non-standard lighting panels 5, and the transverse two ends respectively form downward non-standard pressing member bending parts 7021, and the lower ends of the two non-standard pressing member bending parts 7021 are respectively sealed and installed with non-standard pressing member sealing strips 707 which are in close contact with the non-standard lighting panel; as shown in the figure, the lower ends of the two bending parts 7021 of the non-standard pressing member 702 are provided with non-standard pressing member sealing grooves along the longitudinal direction, the non-standard pressing member sealing grooves are necked opening grooves, the non-standard pressing member sealing strips are made of a material with certain elasticity (such as the EPDM sealing strip in this embodiment), the upper part is provided with an expansion head and is fitted in the non-standard sealing groove through the expansion head, and the lower part is a sealing lip, the sealing lip includes an inclined bar extending outward and downward and a convex sealing part with a downward protrusion inside the inclined bar, the structure is the same as the standard sealing strip, and the specific structure is referred to the description of the standard sealing strip in the above embodiment, and will not be repeated here. Figure 9 The convex sealing part has a downward arc surface which is in elastic contact with the surface of the non-standard lighting panel 5, forming double sealing, the inclined bar faces the direction of incoming water and has a self-tight sealing effect under the pressure of water, and in combination with the sealing arc surface in elastic contact, the sealing effect is further ensured; as shown in the figure, the upper part of the inclined bar extends upward to form a cover strip which closes the outside of the bending part 7021, avoiding water entering the standard sealing groove, and the convex sealing part is a hollow structure, which has better elastic contact sealing performance while saving material for manufacturing;

[0085] As shown in the figure, the transverse two ends of the wing plate 7011 of the T-shaped base respectively form T-shaped base bending parts 70111 which extend upward, and the upper end of the T-shaped base bending part 70111 is provided with a T-shaped base sealing groove along the longitudinal direction, the T-shaped base sealing groove is a necked opening groove, the necked opening groove is provided with a T-shaped base sealing strip, the structure of the T-shaped base sealing strip is the same as that of the non-standard pressing member sealing strip, and the installation direction is opposite; the expansion head is fitted downward in the T-shaped base sealing groove, and the sealing lip holds the corresponding non-standard lighting panel upward, since the T-shaped base sealing strip is made of a material with certain elasticity (such as the EPDM sealing strip in this embodiment), it not only can hold the non-standard lighting panel, but also has certain buffering effect and deformation adaptation ability, thereby prolonging the service life of the whole lighting panel;

[0086] The non-standard connecting device 7 further comprises a C-shaped right-angle non-standard buckle strip 708 buckled to the inner end of the non-standard light panel 5 through a sealing gasket 709. As shown in the figure, the cross section of the C-shaped right-angle non-standard buckle strip 708 is rectangular with one side open, and the C-shaped right-angle non-standard buckle strip is buckled to the inner end (the end corresponding to the adjacent non-standard light panel) of the non-standard light panel 5 through the opening. The inner surface of the C-shaped right-angle non-standard buckle strip 708 is provided with the sealing gasket 709. The sealing gasket of the embodiment is an aluminum foil tape. During construction, the entire aluminum foil tape can be pasted on the inner end of the non-standard light panel and the upper and lower surfaces close to the inner end, and then the C-shaped right-angle non-standard buckle strip 708 is buckled. A certain buckling pre-tightening force can be set between the two wings of the C-shaped right-angle non-standard buckle strip to ensure the buckling strength. A plurality of buckle teeth 7081 (long strip buckle teeth with arc-shaped cross section, of course, they can also be triangular and should be inclined inward to ensure the buckling strength) are processed on the inner surfaces of the two wings. The inner surface of the web is processed with sealing teeth. After buckling, the strip-shaped buckle teeth and the sealing teeth are pressed against the sealing gasket and make the sealing gasket deform, which is used to increase the buckling strength and sealing performance, and is beneficial to protect the end of the non-standard light panel and improve its service life, which will not be described here.

[0087] The C-shaped right-angle non-standard buckle strip 708 extends upward to form a pressure bearing rib 7082 close to the web thereof. The non-standard compression piece 702 downwardly forms a pressure rib 7022, and the non-standard compression piece 702 is fixedly connected to the T-shaped base. The pressure rib 7022 tightly presses the pressure bearing rib 7082 and applies a transverse outward force to the pressure bearing rib 7082. As shown in the figure, the pressure bearing rib 7082 is integrally formed along the length direction of the C-shaped right-angle non-standard buckle strip 708, and the pressure rib is integrally formed along the length direction of the non-standard compression piece. The pressure rib 7022 is located on the inner side of the pressure bearing rib, and the side of the pressure bearing rib 7082 close to the pressure rib 7022 (the inner side of the pressure rib) is processed into an inclined surface. Similarly, the pressure rib is also processed with an inclined surface corresponding to the inclined surface of the pressure bearing rib. When the non-standard compression piece is fixed downwardly on the T-shaped base, the pressure rib 7022 acts on the pressure bearing rib 7082 through the inclined surface to form a downward and downward buckling direction component force (outward) of the C-shaped right-angle non-standard buckle strip 708, so as to further increase the buckling strength and sealing effect of the C-shaped right-angle non-standard buckle strip 708. In particular, the setting of the pressure bearing rib raises the end edge of the non-standard light panel, so that rainwater, cleaning water and the like cannot pass over the pressure bearing rib even after the sealing strip fails, thereby ensuring the sealing and water blocking effect of the non-standard light panel after installation. At the same time, the setting of the pressure rib and the pressure bearing rib also increases the bending resistance of the non-standard compression piece 702 and the C-shaped right-angle non-standard buckle strip 708, thereby ensuring the integrity and strength of the non-standard light panel installation.

[0088] The web 7012 of the T-shaped base is pressed against the lower end of the web of the C-shaped right-angle non-standard buckle strip 708 and exerts a transverse outward force; as shown in the figure, the web 7012 of the T-shaped base expands to the transverse two sides, and the two side surfaces form inclined surfaces which abut against the positions of the bottom corner of the web of the corresponding C-shaped right-angle non-standard buckle strip 708, and exert upward and clamping direction components, and the pressing ribs of the non-standard pressing piece increase the clamping force from the upper and lower directions, so as to ensure the clamping force and sealing performance of the C-shaped right-angle non-standard buckle strip 708 and the non-standard daylighting panel 5, thereby ensuring the integrity of the daylighting panel system; as shown in the figure, the web 7012 of the T-shaped base expands to the transverse two sides to form a hollow structure, which has strong bending resistance and is beneficial to reducing the weight of the component; in this embodiment, the non-standard pressing piece is fixed on the web 7012 of the T-shaped base by screws, which is convenient for construction; in order to ensure the aesthetic appearance and a certain sealing performance at the top, a strip-shaped non-standard buckle cover 703 is further buckled at the upper part of the non-standard pressing piece; as shown in the figure, the transverse two sides of the strip-shaped non-standard buckle cover 703 are smoothly bent downward and form inward protrusions, recesses are arranged at the positions close to the top of the transverse two sides of the non-standard pressing piece 702, the protrusions are embedded in the recesses with a certain pre-tightening force, so that the strip-shaped non-standard buckle cover is buckled on the non-standard pressing piece; as shown in the figure, the end part in the length direction (the end part of the T-shaped base, the non-standard pressing piece and the strip-shaped non-standard buckle cover 703) needs to be buckled with an end cover to ensure sealing while ensuring the appearance; for specific structures, refer to Figure 13 The end cover 608 buckled at the end part of the middle standard connecting device 6 will not be described here.
