[0027] Next, refer to Figures 1-6 To illustrate the formwork support device of an embodiment of the present invention. In an embodiment of the present invention, the formwork support device includes: a reinforcement device, wherein the reinforcement device includes a steel section in a reinforced concrete member, a sleeve screw, and a fixed formwork, wherein the sleeve screw includes a sleeve, a threaded steel bar, and a connecting screw, the sleeve screws are symmetrically arranged on both sides of the steel section, and the connecting screw of the sleeve screw is fixed to the fixed formwork, wherein the sleeve includes a first sleeve and a second sleeve, one end of the threaded steel bar is connected to the first sleeve, and the other end of the threaded steel bar is connected to the connecting screw through the second sleeve.

[0028] Figure 1 This is a schematic elevation view of a steel flange plate reinforced with a sleeve screw according to an embodiment of the present invention. Figure 1As shown, the formwork support device of an embodiment of the present invention includes a reinforcement device, which includes a steel section, a sleeve screw, and a fixed formwork in a reinforced concrete component. The sleeve screw includes a sleeve, a threaded steel bar 11, and a connecting screw 1, wherein the sleeve includes a first sleeve 4 and a second sleeve 5. One end of the threaded steel bar 11 can be connected to the first sleeve 4, and the other end of the threaded steel bar 11 can be connected to the connecting screw 1 through the second sleeve 5. The sleeve screws are symmetrically arranged on both sides of the steel section. The connecting screw 1 of the sleeve screw is fixed to the fixed formwork. For example, the connecting screw 1 can be a high-strength screw specially used for formwork reinforcement. The size of the first sleeve 4 can be equal to half the size of the second sleeve 5. That is, for a unified sleeve model, the second sleeve 5 is a whole sleeve, while the first sleeve 4 is half a sleeve. In the present invention, the threaded steel bar 11 is not completely covered by the sleeve. The sleeve includes a first sleeve 4 and a second sleeve 5.

[0029] Specifically, in Figure 1 In the reinforced concrete component, there are steel sections in the reinforced concrete component and concrete structure 2 in the reinforced concrete component. In the present invention, the reinforcement device includes steel sections in the reinforced concrete component, threaded steel bars 11, a first sleeve 4, a second sleeve 5, a connecting screw 1 and a fixed formwork. The steel sections include a web 3-1 and a flange plate 3-2, and the web 3-1 is welded to the flange plates 3-2 at both ends to form an H-shaped steel. The fixed formwork includes a panel 6, a secondary keel 7 and a main keel 8, and the fixed formwork can be, for example, a steel formwork. The connecting screw 1 can be, for example, a high-strength screw specially used for formwork reinforcement. The first sleeve 4 (half a sleeve), the second sleeve 5 (the entire sleeve), the threaded steel bars 11 and the connecting screw 1 constitute the four parts of the aforementioned sleeve screw, and the specifications of these parts can be selected according to the formwork design results and kept consistent.

[0030] In the present invention, the first sleeve of the sleeve screw is symmetrically welded to the steel section. Furthermore, the first sleeve is symmetrically welded to the flange of the steel section. One end of the threaded rebar is connected to the flange via the first sleeve, while the other end is connected to one end of the connecting screw via the second sleeve. The outer end of the connecting screw is secured to the formwork via a nut and a washer. Specifically, the sleeve screws are symmetrically arranged on either side of the steel section, and the connecting screw 1 of the sleeve screw is secured to the formwork. Furthermore, the first sleeve 4 (half sleeve) is symmetrically welded to the flange 3-2 of the steel section, threading the ends of the rebar to form the threaded rebar 11. For example, one end of the threaded rebar 11 can be connected to the flange 3-2 of the steel section in a reinforced concrete structure via the first sleeve 4 (half sleeve), while the other end can be connected to one end of the connecting screw 1 (e.g., a high-strength screw specifically designed for formwork reinforcement) via the second sleeve 5 (full sleeve), which is tightly attached to the inner surface of the formwork panel. The outer end of the connecting screw 1 can be fixed to the main keel 8 of the forming template through a nut 10 and a washer 9, for example.

[0031] In the embodiment of the present invention, the threaded steel bars that form the sleeve screw are cut to the designed dimensions (threaded steel bar length = distance from the steel section to the reinforced concrete member surface - 0.5 × length of the second sleeve 5). Both ends of the steel bars are threaded, for example, with straight threads. One end of the threaded steel bar 11 is oiled for protection, while the other end is reserved for installation of the second sleeve 5. Thus, the formwork reinforcement is completed by the straight-threaded first sleeve, the straight-threaded second sleeve 5, the threaded steel bar 11, and the connecting screw 1.

[0032] Figure 2 This is a cross-sectional view of a steel section according to an embodiment of the present utility model. Figure 2 As shown, the steel in the steel-concrete structure is usually H-shaped steel. The H-shaped steel of the embodiment of the utility model can include a web 3-1 and flange plates 3-2, wherein the flange plates 3-2 are located on both sides of the web 3-1, and the H-shaped steel is welded by the web 3-1 and the flange plates 3-2 on both sides.

[0033] In the present invention, there are two ways to connect the sleeve screw of the embodiment of the present invention and the steel section of the embodiment of the present invention, that is, the first sleeve 4 can be symmetrically welded on the flange plate 3-2 or the web 3-1 of the steel section.

[0034] Next, taking the welding of the first sleeve 4 on the flange plate 3-2 of the section steel as an example, in order to avoid repetition, the figure does not show the welding of the first sleeve 4 on the web plate 3-1 of the section steel. Figure 3 It is a schematic diagram of the connection between the steel flange plate and the first sleeve according to an embodiment of the present utility model.

[0035] like Figure 3As shown, a first sleeve 4, or half a sleeve, is welded to the flange plate 3-2 of the steel section. Specifically, the present invention determines the specifications of the connecting screws, threaded steel bars, and sleeves, as well as the exact position of each connecting screw, based on the formwork support force calculation and dimensional drawings, and explains the position of the connecting screws to the steel section processing factory. When the steel section is processed in the factory, half of the sleeve 4 is welded to the flange plates 3-2 on both sides of the H-shaped steel according to the designed position. In the present invention, the connecting screws can be high-strength screws specially used for formwork reinforcement.

[0036] Figure 4 Schematic diagram of the steel flange plate connected to the threaded steel bar and the second sleeve according to the embodiment of the present invention. Figure 4 As shown, threaded steel bars 11 and a second sleeve 5 (i.e., the entire sleeve) are screwed onto the steel flange plate of the embodiment of the present invention. Specifically, after the steel bars are tied around the steel-concrete component, the first sleeve 4 on the steel flange plate 3-2 is connected to the threaded steel bars 11 (i.e., the threaded steel bars). Rebars are also arranged around the steel section, including vertical main bars 21, transverse main bars 22, and stirrups 23. If these steel bars around the steel section conflict with the position of the threaded steel bars 11, the steel bars need to be slightly moved to make room for the sleeve bar 11. The threaded steel bars 11 are then connected and tightened to the welded first sleeve 4 on the steel flange plate 3-2 using a special wrench. Simultaneously, the position of the threaded steel bars 11 is appropriately adjusted, and the second sleeve 5 at the other end of the threaded steel bars 11 is tightened, leaving half of the thread open for later use.

[0037] Next, Figure 5 This is a schematic diagram of the utility model using sleeve screws to reinforce the template on the steel flange plate. Figure 5 In the reinforced concrete component, there are steel sections in the reinforced concrete component and concrete structure 2 in the reinforced concrete component. In the present invention, the reinforcement device includes steel sections in the reinforced concrete component, threaded steel bars 11, a first sleeve 4, a second sleeve 5, a connecting screw 1 and a fixed formwork. The steel sections include a web 3-1 and a flange plate 3-2, and the web 3-1 is welded to the flange plates 3-2 at both ends to form an H-shaped steel. The fixed formwork includes a panel 6, a secondary keel 7 and a main keel 8, and the fixed formwork can be, for example, a steel formwork. The connecting screw 1 can be, for example, a high-strength screw specially used for formwork reinforcement. The first sleeve 4 (half a sleeve), the second sleeve 5 (the entire sleeve), the threaded steel bars 11 and the connecting screw 1 constitute the four parts of the aforementioned sleeve screw, and the specifications of these parts can be selected according to the formwork design results and kept consistent.

[0038] In the present invention, the first sleeve of the sleeve screw is symmetrically welded to the flange of the steel section. One end of the threaded rebar is connected to the flange via the first sleeve, while the other end of the threaded rebar is connected to one end of the connecting screw via the second sleeve. The outer end of the connecting screw is secured to the formwork via a nut and a washer. Specifically, the sleeve screws are symmetrically arranged on either side of the steel section, and the connecting screw 1 of the sleeve screw is secured to the formwork. Furthermore, the first sleeve 4 (half sleeve) is symmetrically welded to the steel section flange 3-2, threading the ends of the rebar to form the threaded rebar 11. For example, one end of the threaded rebar 11 can be connected to the steel section flange 3-2 in a reinforced concrete structure via the half sleeve, while the other end of the threaded rebar 11 can be connected to one end of the connecting screw 1 via the second sleeve 5, which is tightly attached to the inner surface of the formwork panel. The outer end of the connecting screw 1 (a high-strength screw specially designed for formwork reinforcement) can be secured to the main keel 8 of the formwork via a nut 10 and a washer 9, for example. When the first sleeve in the sleeve screw is symmetrically welded to the web of the steel section, one end of the threaded steel bar is connected to the web through the first sleeve, and the other end of the threaded steel bar is connected to one end of the connecting screw through the second sleeve, which is not shown in the figure.

[0039] In the embodiment of the present invention, the threaded steel bars that form the sleeve screw are cut to the designed dimensions (threaded steel bar length = distance from the steel section to the reinforced concrete member surface - 0.5 × length of the second sleeve). Both ends of the steel bars are threaded, for example, with straight threads. After threading, one end of the threaded steel bar 11 is oiled for protection, while the other end is reserved for installation of the second sleeve 5. Thus, the formwork reinforcement is completed by the straight-threaded first sleeve, the straight-threaded second sleeve 5, the threaded steel bar 11, and the connecting screw 1.

[0040] exist Figure 5 In addition to the aforementioned formwork support devices (corresponding to the aforementioned steel sections), the formwork is typically reinforced with tension bolts 12 outside the steel sections. These are secured to the main keel 8 of the shaped formwork using, for example, nuts 14 and pads 13. Furthermore, PVC sleeves 15 are used outside the tension bolts 12 to prevent adhesion between the tension bolts 12 and the concrete 2 during concrete pouring, making it easier to remove the tension bolts 12 from the concrete 2 for reuse.

[0041] Figure 6 This is a schematic plan view of the steel flange plate reinforced with sleeve screws after demoulding. Figure 6As shown, the use of sleeve screws to reinforce the formwork on the steel flange after formwork removal clearly demonstrates the significant advancements of this embodiment over the prior art. Specifically, after the concrete strength meets the formwork removal requirements, the high-strength screws specifically designed to reinforce the outer section of the formwork (i.e., the aforementioned connecting screws 1) are first unscrewed from the second sleeve 5, and then the finalized formwork is removed. However, after the finalized formwork is removed, the flange and web of the steel section remain in the concrete 2. The threaded rebar 11 on both sides of the steel section, the first sleeve 4 (half sleeve), and the second sleeve 5 (full sleeve) can also remain in the concrete, providing continued support and increasing construction safety. Furthermore, the connecting screws and finalized formwork can be reused, saving costs and avoiding the need to re-prepare equipment, resulting in excellent economic value. Furthermore, outside the steel section, the tie screws and PVC sleeve 15 remain in the concrete 2. Furthermore, after the formwork is completely removed, the second sleeve 5 can be filled with, for example, cement mortar to effectively seal the area.

[0042] Through the embodiments of the present invention, the present invention can effectively avoid the technical problem of opening holes in steel sections, while increasing the supporting strength of the formwork, enhancing the seismic resistance, and increasing the flexibility and convenience of construction, with unexpected technical effects.

[0043] The above specific embodiments do not limit the scope of protection of this utility model. Those skilled in the art will understand that various modifications, combinations, sub-combinations, and substitutions may occur depending on design requirements and other factors. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model shall be included in the scope of protection of this utility model.
