[0002] With the acceleration of urban construction, high-rise and super high-rise buildings are becoming increasingly common. Ordinary concrete structures can no longer meet their structural requirements, leading to a rise in buildings incorporating steel structures. For this type of structure, the traditional approach, without using profiled steel sheets, is to erect a scaffold and formwork. However, this construction method does not fully utilize the inherent load-bearing capacity of steel-structured buildings, resulting in slow construction speeds and the risk of floor slab cracking. Utility Model Content
[0003] The purpose of this utility model is to overcome the defects of the existing technology and provide a suspended combined formwork support system, which avoids the hidden danger of cracks caused by the newly poured floor slab bearing the upper construction load, and at the same time eliminates the process of scaffolding erection.
[0004] To achieve the above technical effects, this utility model provides a suspended combined formwork support system, which includes:
[0005] Structural steel beams arranged longitudinally;
[0006] Multiple hanging components are evenly arranged along the extension direction of the structural steel beam. Each hanging component includes a hanging part provided on the wing plate of the structural steel beam and two connecting parts that are vertically fixed to both ends of the hanging part and extend towards the bottom of the structural steel beam.
[0007] Multiple sets of template main keel assemblies arranged horizontally are arranged in correspondence with multiple hanging parts. Each set of template main keel assemblies includes two template main keels symmetrically arranged on both sides of the corresponding hanging part and detachably connected to the connecting part on the corresponding hanging part.
[0008] Multiple cantilever supports are provided, each corresponding to one of the multiple hanging components. The multiple cantilever supports are respectively located on the outside of the structural steel beam at the edge position. Each cantilever support includes a cantilever rod arranged laterally and detachably connected to the connecting part of the hanging component at the edge position. The cantilever rod extends outward from the structural steel beam at the edge position, and a support rod is obliquely connected between the extended end and the structural steel beam at the edge position.
[0009] Preferably, each of the connecting parts is provided with a slot for inserting and connecting the corresponding main keel of the template or the cantilever rod, and a support plate for supporting the corresponding main keel of the template or the cantilever rod is detachably installed on the connecting part below the slot.
[0010] Preferably, the connecting part is provided with threads, and a nut for detachably connecting the connecting part to the support plate is screwed onto the connecting part below the support plate, so that after the corresponding main keel of the template or the cantilever rod is inserted into the corresponding slot, the support plate supports the main keel of the template or the cantilever rod.
[0011] Preferably, it also includes a plurality of secondary template keels that are uniformly disposed longitudinally above the plurality of sets of main template keel assemblies and above the plurality of cantilever poles, and a plurality of template bodies laid on the plurality of secondary template keels.
[0012] The technical effects achieved by this utility model due to the adoption of the above technical solution are as follows:

Detailed Implementation
[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] Please see Figures 1 to 5 As shown, this utility model embodiment provides a suspended combined formwork support system, including a longitudinally arranged structural steel beam 1, multiple hanging members 2, multiple sets of formwork main keel assemblies arranged laterally, and multiple cantilever supports 7. The multiple hanging members 2 are evenly arranged along the extension direction of the structural steel beam 1. Each hanging member 2 includes a hanging part 21 disposed on the wing plate of the structural steel beam 1 and two connecting parts 22 vertically fixedly connected to both ends of the hanging part 21 and extending towards the bottom of the structural steel beam 1. Multiple sets of formwork main keel assemblies are arranged one-to-one with the multiple hanging members 2, and each set of formwork main keel assemblies... The system includes two main template keels 5 symmetrically arranged on both sides of the corresponding hanging member 2 and detachably connected to the connecting part 22 on the corresponding hanging member 2; multiple cantilever supports 7 are arranged one-to-one with multiple hanging members 2, and the multiple cantilever supports 7 are respectively arranged on the outside of the structural steel beam 1 located at the edge position. The cantilever support 7 includes a cantilever rod 71 arranged in the transverse direction and detachably connected to the connecting part 22 of the hanging member 2 located at the edge position. The cantilever rod 71 extends to the outside of the structural steel beam located at the edge position, and the extended end is obliquely connected to the structural steel beam located at the edge position by a support rod 72.
[0024] Furthermore, each connecting part 22 is provided with a slot 23 for inserting and connecting the corresponding main keel 5 of the template or the cantilever rod 71. A support plate 3 for supporting the corresponding main keel 5 of the template or the cantilever rod 71 is detachably installed on the connecting part 22 below the slot 23. Preferably, in this embodiment, the connecting part 22 is provided with threads, and a nut 4 for detachably connecting the connecting part 33 to the support plate 3 is screwed onto the connecting part 22 below the support plate 3. Thus, after the corresponding main keel 5 of the template or the cantilever rod 71 is inserted into the corresponding slot 23, the support plate 3 supports the main keel 5 of the template or the cantilever rod 71. In this embodiment, there are two nuts 4. It should be noted that in this embodiment, each hanging component 1 is made of two parallel steel bars bent into an inverted U-shape. The steel bars are HPB300 with a diameter of 16mm. A slot 23 is formed between the two steel bars for inserting and placing the main keel 5 of the template on both sides. The width of the hanging part 21 formed by the bent steel bars is greater than the width of the wing plate of the structural steel beam 1, thereby realizing the hanging on the wing plate. The support plate 3 is made of angle steel. By setting threads in the connection part 22, the height of the support plate 3 can be easily adjusted, thereby realizing the installation height of the main keel 5 of the template or the cantilever rod 71.
[0025] Please see Figure 5 As shown, in this embodiment, a connecting rod 73 is fixedly connected between the end of the cantilever rod 71 near the structural steel beam 1 and the support rod 72. The connecting rod 73 is fixedly connected to the web of the structural steel beam 1. It should be noted that in this embodiment, the cantilever rod 71 is made of No. 3 channel steel, and the support rod 72 and the connecting rod 73 are both made of angle steel. The cantilever rod 71 and the connecting rod 73, the support rod 72 and the connecting rod 73, and the structural steel beam 1 are all connected and fixed using connecting angle steel 74 and connecting screws 75.
[0026] Please see Figure 1 As shown, the hanging combined formwork support system of this utility model embodiment also includes multiple secondary formwork keels 6 that are evenly arranged longitudinally above multiple sets of main formwork keel components and multiple cantilever rods 71, and multiple formwork bodies 8 laid on the multiple secondary formwork keels 6. In this embodiment, the main formwork keel 5 is made of 10# I-beams with a laying spacing of 1000mm, the secondary formwork keels 6 are made of square steel pipes with specifications of 40mm x 40mm x 2mm (section length x width x thickness) with a laying spacing of 200mm, and the formwork body 8 is made of 15mm thick film-coated plywood.
[0027] The construction process for the suspended combined formwork support system of this utility model embodiment includes:
[0028] 1) Hanging component processing:
[0029] The mounting brackets are made of HPB300 grade round steel with a diameter of 16mm.
[0030] 2) Installation of hanging components, main formwork keel, and cantilever supports:
[0031] Precise layout is used to determine the installation positions of the hanging components. Before installation, two parallel inverted U-shaped steel bars are connected into a single unit using a support plate, washers, and nuts to form the hanging component. The hanging component is then placed according to the layout lines. This facilitates the installation of the main formwork joists. After the main formwork joists are installed, the support plates, washers, and nuts are finally installed, and the height is adjusted. The main formwork joists use 10# I-beams spaced 1000mm apart. It should be noted that cantilever supports are installed at cantilever locations.
[0032] 3) Installation of the secondary keel and the formwork body.
[0033] After the main formwork joists and cantilever supports are installed and secured, the secondary formwork joists are installed and the formwork body is laid. The secondary formwork joists are laid at 200mm intervals. The formwork body is made of 15mm thick film-coated plywood. Reinforcement binding, concrete pouring, and curing can only be carried out after the entire formwork support system is completed.
[0034] 4) Removal of the template body.
[0035] To ensure the safe removal of the formwork, first loosen the nuts to lower it by 1-2 cm; then remove the secondary formwork joists, followed by removing the formwork body attached to the top slab of the floor, then removing the main formwork joists, and finally transporting it to the floor slab using a hydraulic lifting platform.
[0036] All parts not described in this utility model are the same as or can be implemented using existing technology. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of this utility model, the scope of which is defined by the appended claims and their equivalents.
