[0040] Example
[0041] like Figure 1-2As shown, the embodiment of the utility model provides a lower bottom cover suitable for hard protection of cantilever scaffolding, including: a main beam 1, installed on the outer wall 2 of the building, arranged below the cantilever frame 3, serving as a gravity-bearing connection support for the lower bottom cover structure; a plurality of bottom secondary purlins 4, one end of each bottom secondary purlin 4 is connected to the main beam 1 to form a bottom frame; a side main purlin 5, arranged on the outer side of the cantilever frame 3, and connected to the other end of each bottom secondary purlin 4; a plurality of side secondary purlins 6, arranged on the outer side of the cantilever frame 3, the bottom of each side secondary purlin 6 is connected to the side main purlin 5 to form a side frame; the top of the side secondary purlin 6 is higher than the bottom surface of the cantilever frame 3, and there is a gap between the side frame and the cantilever frame 3; the outer side of the bottom surface of the bottom frame is covered with a layer of protective skin 7, the protective skin 7 is bent and extends toward the side frame, and covers the outer side of the side frame. The protective skin 7 can not only provide physical protection to prevent objects from falling, but also has the characteristics of waterproof, dustproof and wear-resistant to adapt to the outdoor environment. In the actual application process, the protective skin 7 can be customized and printed with the company's logo, slogan or promotional pattern to enhance the display of the corporate image.
[0042] Specifically, the main beam 1 is connected to the building outer wall 2, so that the building outer wall 2 can support the entire lower bottom cover structure. Therefore, the connection stability between the main beam 1 and the building outer wall 2 is critical. In the embodiment of the utility model, as a preferred embodiment, Figure 3 As shown, the main beam 1 can be connected to the building exterior wall 2 by multiple expansion screws 14. This structure is not only flexible in use and convenient for disassembly, but also ensures the stability of the connection. In the embodiment of the utility model, the main beam 1 is connected to multiple bottom secondary keels 4. The main beam 1 and each bottom secondary keel 4 are preferably arranged vertically, so that the distance between the base frame and the cantilever frame 3 formed in this way can be stably controlled, thereby improving the support uniformity of the lower bottom cover structure, thereby improving the stability of the lower bottom cover structure. The side main keels 5 are arranged opposite to the main beam 1 and are respectively connected to the two ends of the bottom secondary keels 4. The side main keels 5 serve as the base frame and the side The corner connection structure between the frames ensures that the side frames formed by multiple side secondary keels 6 are stably connected to the base frame, forming stable enclosure structure supports on the periphery of the cantilever frame 3 in two directions, and then a protective skin 7 is set on the enclosure structure, and the protective skin 7 is bent at the corner where the base frame and the side frame are connected to form an integrated seal and cover. This structure is not only strong and sturdy, but also has strong sealing properties. Since the protective skin 7 at the corner is bent and integrated, it is not easy to be lost during use, which reduces the difficulty of sealing the corner and improves the sealing of the corner, thereby reducing safety hazards during construction.
[0043] Furthermore, if Figure 4As shown, the top of each side secondary keel 6 is connected to the first upper flange keel 8, the first upper flange keel 8 is arranged in parallel with the side main keel 5, and multiple upper flange secondary keels 9 are connected to the first upper flange keel 8, and each upper flange secondary keel 9 is arranged perpendicular to the first upper flange keel 8. Specifically, the first upper flange keel 8 is arranged in parallel with the side main keel 5, which can provide additional support and enhance the lateral stability of the entire structure. The upper flange secondary keel 9 is arranged perpendicular to the first upper flange keel 8. This layout can increase the vertical support of the structure and improve the overall load-bearing capacity. It should be noted that in order to ensure that the connection between the first upper flange keel 8 and the side secondary keel 6 and the upper flange secondary keel 9 is firm and reliable, bolts, welding or special clamps can be used, which are not limited here, as long as the purpose of stable connection can be achieved. It should also be noted that the number of side secondary keels 6 and upper flange secondary keels 9 is not limited here, and can be set according to actual conditions, as long as the purpose of sufficient support stability can be achieved. More preferably, each upper flange secondary keel 9 is connected to the second upper flange keel 10 , and the second upper flange keel 10 and the first upper flange keel 8 are respectively arranged at two ends of each upper flange secondary keel 9 and are arranged parallel to each other.
[0044] In order to further improve the firmness and stability of the entire lower bottom cover structure, the lower bottom cover of the embodiment of the utility model also includes a hanger mechanism, which includes a first hanger 11 and a second hanger 12 which are perpendicular to each other. One end of the first hanger 11 is connected to the first upper flange keel 8, and the other end is connected to the side main keel 5. The first hanger 11 is arranged in parallel with each side secondary keel 6; one end of the second hanger 12 is connected to the first hanger 11, and the other end is connected to the cantilever frame 3. Specifically, the vertical arrangement of the first hanger 11 and the second hanger 12 provides a stable support point for the entire cantilever scaffolding, which helps to improve the stability of the overall structure. The first hanger 11 is arranged in parallel with the side secondary keel 6, which helps to evenly distribute the load and reduce local stress concentration. The second hanger 12 connects the first hanger 11 and the cantilever frame 3, which can further disperse the load of the lower bottom cover structure and distribute it to the cantilever frame 3, further improving the stability of the structure. The design of the hanger mechanism should be convenient for construction personnel to quickly install and disassemble, reducing construction time and cost.
[0045] As a preferred embodiment of the utility model, the hanger mechanism also includes a third hanger 13, one end of the third hanger 13 is connected to the second hanger 12, and the other end is connected to the second upper flange keel 10; the third hanger 13 is arranged vertically with the second hanger 12, and the third hanger 13 contacts the outer side of the cantilever frame 3. The third hanger 13 is arranged vertically with the second hanger 12, providing an additional support point, which helps to disperse the load of the cantilever frame 3 and improve the stability of the overall structure. The third hanger 13 contacts the outer side of the cantilever frame 3 to ensure the stability and friction of the contact point. Preferably, the main beam 1 is arranged in parallel with the side main keel 5, because the parallel arrangement of the main beam 1 and the side main keel 5 helps to more evenly distribute the load on the cantilever frame 3 and reduce local stress concentration. At the same time, it can provide better lateral stability and reduce structural deformation caused by wind or other external factors. The parallel arrangement simplifies the installation process because the construction personnel can install the main beam 1 and the side main keel 5 in a straight line. More preferably, each bottom secondary purlin 4 is arranged in parallel and at equal intervals. Of course, in other embodiments, each bottom secondary purlin 4 can be arranged as a cross structure, which is not limited here. Returning to the embodiment of the utility model, the parallel arrangement of the bottom secondary purlins 4 helps to evenly distribute the load on the cantilever frame 3 and avoid local overload caused by uneven load. The parallel arrangement of the bottom secondary purlins 4 simplifies the installation process, and construction workers can quickly install them in a straight line, thereby improving construction efficiency.
[0046] For example, the back cover provided by the embodiment of the utility model adopts primary and secondary keels to be fixed to the cantilever frame 3 and the outer side of the building outer wall 2, and an L-shaped galvanized iron sheet sprayed with corporate culture propaganda is installed on the bottom frame and the side frame, and the back cover frame structure is arranged along the building outer wall 2. Specifically, Figure 1-Figure 4 As shown, the bottom secondary keel 4, the side main keel 5, the main beam 1, the side secondary keel 6, the first upper flange keel 8, the second upper flange keel 10, the side secondary keel 6, etc. provided in the embodiment of the utility model are all rectangular square tubes, and are 30mmx30mmx1.0mm rectangular tubes, and the bottom frame structure presents an L-shaped structure. The lower cantilever length of the L bottom frame structure is 1.5 meters, the vertical height is 0.5 meters, and the upper flange width is 0.25mm. After the cantilever main beam 1 of the cantilever frame 3 is installed, the upper frame and hard protection are laid, and then the construction of the L-shaped frame structure of the lower bottom of the utility model embodiment is started. It should be noted that the L-shaped frame structure here is composed of a base frame and a side frame. A horizontal line is popped up along the bottom opening 200mm away from the cantilever frame 3. More specifically, the main beam 1 is arranged along the exterior wall 2 of the building, and the keel adopts a model of @500mm expansion bolts are used to fix the expansion bolts and the main beam 1 is connected by welding. After the main beam 1 along the building outer wall 2 is constructed, the bottom secondary keel 4 and the side main keel are constructed. The side main keel includes the side main keel 5, the first upper flange keel 8 and the second upper flange keel 10. The side main keel is made of steel bar. The galvanized round steel is used to fix the T-type hanger, and the steel bar hanger is connected to the cantilever frame 3 by single-sided welding. The welding length is greater than or equal to 200mm. One end of the T-type hanger is firmly welded to the cantilever frame 3, and at the same time, it is respectively connected to the side main keel 5 of the lower bottom surface and the first upper flange keel 8 and the second upper flange keel 10 of the bottom cover facade. All welding connection points are sprayed with silver powder anti-rust paint after acceptance.
[0047] After the main keel construction on the side is completed, the bottom secondary keel 4 is constructed. The bottom secondary keel 4 is made of the same material as the main keel on the side. The bottom secondary keel 4 uses a 30x30x1.0 rectangular tube with a model of @500mm. The main and secondary keels form a stable rectangular frame unit. The bottom keel of the stable rectangular frame system bears its own load and the weight of the galvanized iron sheet panel.
[0048] The side secondary keel 6 is constructed. The side secondary keel 6 uses a 30x30x1.0 rectangular tube with a model of @1000mm and is welded to the two main keels on the side to form a rectangular frame unit. The width of the upper flange of the bottom cover is 250mm. One end of the upper flange 250mm long rectangular tube is welded to the T-type hanger and the other end is welded to the side main keel 5 rectangular tube, with a spacing of 1000mm. A 30x30x1.0 rectangular tube is set along the outside of the building to form a rectangular frame unit with a width of 250mm. It forms an overall stable frame with the side rectangular unit.
[0049] Check whether the steel bar hanger and all the welding points of the primary and secondary keels are firmly welded, and repair the loose parts with anti-rust paint. After the inspection is completed, the L-shaped galvanized iron sheet is constructed at the bottom. The iron sheet is folded into an L shape in advance by a plate rolling machine, and advertisements and promotional slogans, corporate logos, etc. are sprayed on it according to the requirements of the corporate visual identification system. Rivets are used to fix the iron sheet and the keel. The above structure.
