The supporting formwork formwork frame is fixed on the steel beam support. The steel beam support includes a supporting cross section which is perpendicular to the extension direction of the steel beam and is arranged on the upper surface of the steel beam, a supporting vertical section which is fixed on the lower surface of the supporting cross section and whose side is in contact with the upper flange and the lower flange of the steel beam at the same time, and a supporting oblique section which is obliquely connected between the supporting cross section and the supporting vertical section. The special-shaped limiting component includes two first limiting components arranged between the supporting vertical section and the upper flange of the steel beam and between the supporting vertical section and the lower flange of the steel beam, and a second limiting component arranged between the supporting cross section and the upper flange of the steel beam, to provide a stable fulcrum for the formwork frame, thereby avoiding the waste of material and labor costs caused by the full-hall erection of the beam formwork formwork frame with the ground as the fulcrum.

[0029] The present application is further described in detail below in conjunction with the accompanying drawings. It is necessary to point out here that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technical personnel in this field can make some non-essential improvements and adjustments to the present application based on the above application content. Example

[0030] The present invention discloses a steel beam support system of a formwork support frame and a construction method thereof. Figure 1As shown, the steel beam support system of the formwork frame includes an I-beam 1, a vertical support steel plate 2 is provided on one side of the I-beam 1 and along its own longitudinal direction, a transverse support steel plate 3 is fixedly installed on the top of the vertical support steel plate 2, the vertical support steel plate 2 and the transverse support steel plate 3 are vertically arranged and fixedly connected by an oblique support steel plate 4, the vertical support steel plate 2, the transverse support steel plate 3 and the oblique support steel plate 4 support a support structure with a right-angled triangle structure in cross section, and the triangle is a stable geometric shape; the sides of the triangle can effectively transfer the force to each corner point when subjected to force, therefore, the support structure formed by the right-angled triangle can effectively resist external force; the oblique support steel plate 4 plays a key role in transmitting and distributing the force, and its design can effectively transfer or guide the load, for example, when subjected to lateral force, the force can be transferred to the vertical support through the oblique support and then to the foundation.

[0031] like Figure 1 As shown, the right-angled triangle support structure has good stability; by dividing the support into vertical, lateral and oblique directions, it can effectively resist loads in different directions, thereby improving the overall bearing capacity; the setting of the oblique support steel plate 4 increases the structure's ability to resist lateral displacement, especially when encountering lateral loads or wind loads, the overall stiffness can be increased.

[0032] like Figure 1 As shown, the support structure is symmetrically arranged about the central axis of the I-beam 1 , and is used to play a supporting role on both sides of the I-beam 1 .

[0033] like Figure 1 As shown, the vertical support steel plate 2, the transverse support steel plate 3 and the oblique support steel plate 4 are welded into one body. Welding makes the support structure form a whole, which can greatly improve the rigidity and stability of the whole structure and reduce the deformation under the action of load. The enhanced overall rigidity helps to resist external forces more effectively, especially when subjected to impact loads or wind loads.

[0034] like Figure 1 As shown, the transverse supporting steel plate 3 is provided with a first extension portion 5 extending along its own transverse direction. The first extension portions 5 of the transverse supporting steel plates 3 on the two supporting structures respectively span the tops of both sides of the I-beam 1 and form a snap-in groove 6 at the joint. The first extension portion 5 of the transverse supporting steel plate 3 is designed to span both sides of the I-beam 1, which can effectively provide lateral stability and avoid excessive deformation of the structure under lateral loads; the snap-in groove 6 formed at the joint can provide a stable installation position for the positioning steel plate 7; a positioning steel plate 7 is provided inside the snap-in groove 6, and an anchor nail 8 is provided inside the positioning steel plate 7. The anchor nail 8 inside the positioning steel plate 7 is used to firmly lock the supporting steel plate on the top of the I-beam 1 to achieve a strong connection.

[0035] like Figure 1 As shown, the first extension portion 5 of the transverse support steel plate 3 on the two support structures is fixed to the top of the I-beam beam 1 by positioning the steel plate 7 and the anchor 8; the use of the anchor 8 provides additional strength for the connection, which can effectively resist pull-out and shearing under the action of external force, thereby ensuring the safety and stability of the transverse support structure.

[0036] like Figure 1 As shown, the design of a cross-over I-beam 1 increases the stability of the structure, and can effectively resist lateral or lateral external loads, such as lateral forces caused by wind, earthquakes, etc.; through the snap-in groove 6 and anchor nail 8 system, the construction process can be simplified, and the lateral support steel plate 3 can be quickly positioned and fixed, saving installation time and labor costs.

[0037] like Figure 1 and Figure 2 As shown, the transverse support steel plates 3 on the two supporting structures form a steel beam support on the top of the I-beam 1; this structure can effectively disperse and transfer the load applied to the formwork and enhance the overall bearing capacity. At least two limiting steel bars 9 are arranged on the top of the steel beam support, and the limiting steel bars 9 match the steel pipes 10 used for erecting the formwork; the limiting steel bars 9 are arranged on the top of the steel beam support to play a limiting and guiding role to ensure that the position of the formwork is correct and meets the design requirements when it is erected; the setting of the limiting steel bars 9 can prevent the formwork from shifting or tilting during the load application process; after the steel pipes 10 are inserted into the limiting steel bars 9, a stable support grid can be formed to ensure that the load on the formwork is evenly distributed; through precise matching, the steel pipes 10 and the limiting steel bars 9 can effectively limit the movement of the formwork and maintain the stability of the formwork.

[0038] like Figure 1 and Figure 2 As shown, the steel beam support structure can improve the overall stability of the formwork support system and ensure that the formwork will not be deformed or collapsed due to load during the construction process; by using the combination design of limiting steel bars 9 and steel pipes 10, construction workers can set up the formwork relatively easily, reducing the complex operations caused by unstable formwork and improving construction efficiency.

[0039] like Figure 1 and Figure 2As shown, a lateral protection block 11 is arranged on the top of the steel beam support, and the lateral protection block 11 is located on the outside of the limiting steel bar 9, and the lateral protection block 11 is arranged at equal angles around the central axis of the limiting steel bar 9. The lateral protection block 11 is located on the outside of the limiting steel bar 9, and its main purpose is to provide additional protection and support effects; this design can effectively prevent the lateral displacement of the formwork and related components, and at the same time provide support and guidance for the erected steel pipe 10; the lateral protection block 11 is arranged at equal angles around the central axis of the limiting steel bar 9, which can ensure that each protection block is evenly distributed around; this symmetrical structure helps to balance the load, reduce local stress concentration, and improve overall stability; the placement space formed between the inner surface of the lateral protection block 11 and the outer ring surface of the limiting steel bar 9 matches the wall thickness of the steel pipe 10, and this design ensures that the steel pipe 10 can be smoothly inserted into the protection block; this cooperation is not only convenient for installation, but also ensures a firm connection between components and reduces relative movement during construction.

[0040] like Figure 1 and Figure 2 As shown, the lateral protection blocks 11 provide additional support, which can effectively prevent the template from lateral displacement during construction, improve construction safety, and reduce potential accident risks; this structural design helps to evenly distribute the load, reduce excessive pressure on a single component, and thus extend the service life of the template and support structure.

[0041] like Figure 1 and Figure 2 As shown, a first reinforcing member 12 is arranged between the bottom surface of the upper flange of the I-beam 1 and the vertical supporting steel plate 2, and a second reinforcing member 13 is arranged between the top surface of the lower flange of the I-beam 1 and the vertical supporting steel plate 2. The first reinforcing member 12 and the second reinforcing member 13 are respectively fixedly connected to the I-beam 1 and the vertical supporting steel plate 2 by screws. The first reinforcing member 12 is arranged between the bottom surface of the upper flange of the I-beam 1 and the vertical supporting steel plate 2 to enhance the connection strength and stability of the overall structure; the second reinforcing member 13 is located between the top surface of the lower flange of the I-beam 1 and the vertical supporting steel plate 2. It plays the same role between the top surface of the lower flange of the I-beam 1 and the vertical supporting steel plate 2; by arranging a reinforcement between the I-beam 1 and the supporting steel plate and fixing them with screws, a more stable connection can be formed between the two parts; the screw connection provides strong pull-out resistance and shear resistance, and improves the overall bearing capacity of the connection; the reinforcement can effectively disperse the load applied to the vertical supporting steel plate 2, so that the load is more evenly transferred to the I-beam 1, reducing the local stress concentration phenomenon and improving the durability of the structure.

[0042] like Figure 1 and Figure 2As shown, the first reinforcement 12 and the second reinforcement 13 have the same structure, and the first reinforcement 12 and the second reinforcement 13 are used to connect and reinforce the I-beam 1 and the vertical support steel plate 2; specifically, the first reinforcement 12 includes a transverse support member 1201 and a longitudinal support member 1202, and the transverse support member 1201 and the longitudinal support member 1202 are vertically arranged, and the transverse support member 1201 and the longitudinal support member 1202 are respectively fixedly connected to the I-beam 1 and the vertical support steel plate 2, and the transverse support member 1201 and the longitudinal support member 1202 are fixedly connected via the diagonal support member 1203.

[0043] like Figure 1 and Figure 2 As shown, the first reinforcement member 12 is composed of a transverse support member 1201, a longitudinal support member 1202 and an oblique support member 1203; the transverse support member 1201 and the longitudinal support member 1202 are vertically arranged to form a stable frame structure; the oblique support member 1203 provides additional support, thereby enhancing the overall rigidity and stability of the connection part; the transverse support member 1201 and the longitudinal support member 1202 are fixedly connected to the I-beam 1 and the vertical support steel plate 2 respectively, which can effectively disperse the external force applied to the connection part; the oblique support member 1203 can guide the stress to be transmitted in a more optimal manner, reduce local force concentration and improve the bearing capacity; by adding the oblique support member 1203, the structure can better resist deformation and damage when subjected to shear force and compression force; these supports work together to keep the connection point stable when subjected to forces in multiple directions.

[0044] like Figure 1 and Figure 2 As shown, a fixing block 14 is provided on the longitudinal support member 1202, and a notch 15 is provided inside the fixing block 14. The notch 15 of the fixing block 14 of the first reinforcement 12 and the notch 15 of the fixing block 14 of the second reinforcement 13 are connected by a deformable flexible steel plate 16. The flexible steel plate 16 is in an arc-shaped structure in a natural state. By means of an adjustment component 17 arranged on the flexible steel plate 16, the arc of the flexible steel plate 16 is deformed, thereby increasing the length of the flexible steel plate 16 in the longitudinal direction, and then generating a longitudinal force between the first reinforcement 12 and the second reinforcement 13. The generation of this force can effectively resist the load of the steel beam formwork on the I-beam 1; it can help optimize the stress distribution, so that the force on the I-beam 1 and its connection parts is more uniform, reducing local stress concentration, thereby reducing the risk of material fatigue or damage.

[0045] like Figure 1 and Figure 2As shown, the middle section of the flexible steel plate 16 is smaller than the cross-sectional area of ​​its upper and lower ends. When the flexible steel plate 16 is subjected to external force, a certain stress concentration will be formed at the position with a smaller middle section, causing the material in this part to be more easily bent and deformed when subjected to force; this design allows the force to be evenly distributed to the larger cross-sections at the upper and lower ends, thereby effectively managing and controlling the behavior of the material during the force process; the small middle cross-sectional design increases the flexibility of the material, making it easier to bend or deform, while the larger cross-sectional areas at the upper and lower ends provide the necessary rigidity; this combination allows the flexible steel plate 16 to effectively resist external loads under small deformations while maintaining structural stability; this structural design allows the flexible steel plate 16 to effectively deform when subjected to instantaneous or dynamic loads, adapt to load changes, and thereby reduce the risk of material fatigue.

[0046] like Figure 2 and Figure 3 As shown, specifically, the adjustment component 17 includes an adjustment rod 1701, a threaded hole 1702 arranged in the vertical supporting steel plate 2 and a through hole arranged in the middle of the flexible steel plate 16, the adjustment rod 1701 is provided with a smooth portion and a threaded portion 1704 matching the threaded hole 1702, the smooth portion of the adjustment rod 1701 passes through the through hole and is fixedly connected with a stopper 1705, the cross-sectional size of the stopper 1705 is larger than the cross-sectional size of the through hole, and a threaded wrench 1703 is threadedly connected to the threaded portion 1704 of the adjustment rod 1701.

[0047] like Figure 2 and Figure 3 As shown, the smooth portion of the adjusting rod 1701 can freely pass through the through hole of the flexible steel plate 16, while the threaded portion 1704 can be threadedly connected to the threaded hole 1702 in the vertical supporting steel plate 2; when the threaded wrench 1703 is rotated, the engagement of the thread will cause the adjusting rod 1701 to be horizontally displaced. When the adjusting rod 1701 is displaced, the adjusting rod 1701 moves laterally with the block 1705 until the flexible steel plate 16 is guided to deform. This method uses the threaded wrench 1703 for adjustment, which is simple to operate and does not require complicated tools or equipment. It can be completed by manual rotation; this can improve convenience and efficiency during use.

[0048] The construction method of the steel beam support system of the formwork support frame includes the following construction steps: S1: According to the size of the I-beam 1 and the length of the concrete beam, an appropriate number of supporting structures with a right-angled triangle structure are welded on the ground; S2: hoist the welded support structure onto the I-beam 1 below the concrete beam, so that the first extension 5 on the transverse support steel plate 3 is erected on the upper surface of the I-beam 1, and two support structures are installed symmetrically about the center line of the I-beam 1; S3: Cover the positioning steel plate 7 in the clamping groove 6 of the first extension part 5 of the transverse support steel plate 3 on the two support structures, and fix the first extension part 5 of the transverse support steel plate 3 on the two support structures to the top of the I-beam 1 through the anchor nail 8 to form a steel beam support; S4: The first reinforcement member 12 and the second reinforcement member 13 are used to stably fix the I-beam beam 1 and the vertical support steel plate 2 together through screws; S5: welding the limiting steel bars 9 and the lateral protection blocks 11 on the steel beam support according to the position of the formwork support frame, and then inserting the lower end of the steel pipe 10 used for setting up the formwork between the limiting steel bars 9 and the lateral protection blocks 11; S6: Turn the threaded wrench 1703 so that the adjusting rod 1701 pulls the flexible steel plate 16 to deform, and the flexible steel plate 16 generates a longitudinal force between the first reinforcement member 12 and the second reinforcement member 13; S7: Finally, the formwork for the concrete beam is erected at the position of the limiting steel bar 9, and the construction of the steel beam support system of the formwork frame is completed.

[0049] Working principle: During the construction process, according to the specifications of the I-beam 1 and the length of the concrete beam, the construction workers need to weld an appropriate number of right-angled triangle support structures on the ground. Then the welded support structure is hoisted under the I-beam 1, ensuring that the first extension 5 of the support structure is erected on the upper surface of the I-beam 1 and installed symmetrically about the center line of the I-beam 1. This provides balance and stability for the overall structure.

[0050] The positioning steel plate 7 is covered in the clamping groove 6 of the transverse supporting steel plates 3 of the two supporting structures, and is fixed to the top of the I-beam 1 using anchor nails 8. In this way, a stable steel beam support is formed, and the bearing capacity of the supporting structure is enhanced.

[0051] The first reinforcement 12 and the second reinforcement 13 are then used to stably fix the I-beam 1 and the longitudinal support steel plate together through screws. Then, the limiting steel bars 9 and the lateral protection blocks 11 are welded on the steel beam support according to the position of the formwork frame. These limiting steel bars 9 and protection blocks provide space limitation and lateral support during the formwork process, ensuring the accurate position of the formwork frame.

[0052] By adjusting the threaded wrench 1703, the adjusting rod 1701 pulls the flexible steel plate 16 to deform, thereby generating a longitudinal force between the first reinforcement member 12 and the second reinforcement member 13. This step is used to fine-tune the support structure to adapt to different construction requirements and loading conditions.

[0053] Finally, the formwork of the concrete beam is erected at the position of the limit steel bar 9, and the steel beam support system of the formwork support frame is completed. This step ensures that there is sufficient support during the concrete pouring process to prevent the formwork from deformation or displacement.

[0054] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
