[0002] In the construction industry, formwork support systems are crucial structures for ensuring the quality of concrete pouring and construction safety. Structural beam support systems often use circular steel pipes from scaffolding as the main support frame. However, with the increasing scale and complexity of construction projects, circular steel pipes have revealed many limitations in practical applications. Due to the cross-sectional characteristics of circular steel pipes, they are prone to local instability under stress, resulting in limited overall load-bearing capacity and making it difficult to meet the needs of large-span, medium-to-large load structures.
[0003] Therefore, there is an urgent need to design a keel reinforcement component and a beam under-support system with the component to solve the technical problems existing in the scaffolding support in the current technology. Utility Model Content

The structure is reasonable. The guard plate configured in the keel reinforcement component increases the contact area of the components, and the pad increases the friction between the components, thereby ensuring the reliability of the fixation. The main keel and the secondary keel are made of square steel pipes. Square steel pipes have a regular cross-sectional shape and a large moment of inertia, which can withstand greater loads.
[0005] To solve the above-mentioned technical problems, this utility model provides a keel reinforcement component and a beam support system having the component, which includes a lock that covers the keel to be fixed from the side; the number of the locks is a pair, which are arranged at vertical intervals.

[0007] It also includes a pair of clamps, each clamp having a pair of fixing holes arranged vertically; the clamps are fitted onto the U-bolts of the vertically spaced locks and locked in place with nuts.
[0008] In some embodiments, the length of the guard plate is greater than the arc segment of the U-bolt.
[0009] In some embodiments, the vertical height of the guard plate is 30-50mm.
[0010] In some embodiments, the pad is made of rubber and its vertical height is less than or equal to the vertical height of the guard plate.
[0011] In some embodiments, the protective pad is made of silicone rubber with a thickness of 2-3 mm.
[0012] In some embodiments, the length of the pad is less than the length of the guard plate.
[0013] In some embodiments, the keel reinforcement assembly further includes a tie plate that is obliquely connected to the U-bolts of the upper lock and the U-bolts of the lower lock.
[0014] In some embodiments, the fixing hole is an elongated hole that is arranged along the length of the clamp.
[0015] In some embodiments, the inner sidewall of the pad is provided with a plurality of protrusions, the protrusions having a circular or rectangular cross-section and being evenly distributed.
[0016] Meanwhile, this utility model also provides a beam support system, which includes a scaffold assembly, a main keel, a secondary keel, and the aforementioned keel reinforcement assembly.

The same reference numerals are used to indicate the same parts.
[0035] A schematic diagram of the keel reinforcement component 100 of this utility model is shown below. Figure 1 As shown. The keel reinforcement assembly 100 includes a lock 10 that covers the keel to be fixed from the side; the number of locks 10 is a pair, which are arranged at vertical intervals.
[0036] Furthermore, the lock 10 includes a U-bolt 11, such as Figure 2 As shown, a protective plate 12 is welded inside the U-bolt 11. The protective plate 12 is located on the opposite side of the opening of the U-bolt 11 to increase the contact area between the lock 10 and the side of the keel. A pad 13 is provided on the inner side of the protective plate 12. The pad 13 is adhered to the protective plate 12 to prevent the protective plate 12 from slipping against the keel.
[0037] It should be noted that the end of the U-bolt 11 is provided with a threaded section so as to achieve locking and fixation by means of a nut.
[0038] Figure 1 In the embodiment shown, the keel reinforcement component 100 also includes a pair of clamps 20, each clamp 20 having a pair of fixing holes 21 arranged vertically; the clamps 20 are fitted onto the U-bolts 11 of the locks 10 arranged vertically at intervals and are locked in place with nuts.
[0039] Furthermore, the fixing hole 21 is an elongated hole, which is set along the length direction of the clamp 20 to improve the convenience of installation and fixing.
[0040] In this invention, the length of the guard plate 12 is greater than the arc-shaped segment of the U-bolt 11. The length of the guard plate 12 refers to its dimension along the length direction of the U-bolt 11.
[0041] Furthermore, the vertical height of the guard plate 12 is 30-50mm. Preferably, the vertical height of the guard plate 12 is 40mm to appropriately increase the contact area between the lock 10 and the side of the keel.
[0042] Figure 1 In the illustrated embodiment, the pad 13 is made of rubber, and its vertical height is less than or equal to the vertical height of the guard plate 12. Preferably, the guard plate pad 13 is made of silicone rubber, and its thickness is 2-3 mm.
[0043] Furthermore, the length of the pad 13 is less than the length of the guard plate 12, and the pad 13 abuts against the side of the keel.
[0044] Figure 3This is a schematic diagram of a keel reinforcement component 100 provided in another embodiment of the present utility model. The keel reinforcement component 100 also includes a tie plate 30, which is obliquely connected to the U-bolt 11 of the upper lock 10 and the U-bolt 11 of the lower lock 10.
[0045] Figure 4 This is a top view of a lock provided in another embodiment of the present invention. Figure 5 yes Figure 4 A magnified view of a portion of point A in the middle.
[0046] The inner wall of the pad 13 is provided with a plurality of protrusions 13a, the protrusions 13a having a circular or rectangular cross-section and being evenly distributed. The protrusions 13a increase the surface roughness of the guard plate 13, ensuring the reliability of the lock 10 in place.
[0047] Figures 6 to 8 This is a schematic diagram of a beam support system provided in an embodiment of the present invention. The beam support system includes a scaffolding assembly 400, a main keel 200, a secondary keel 300, and the aforementioned keel reinforcement assembly 100.
[0048] Furthermore, the secondary keel 300 is arranged along the length of the beam, the main keel 200 is arranged vertically below the secondary keel 300, and the keel reinforcement component 100 is connected between the scaffolding component 400 and the main keel 200 to fix the main keel 200 to the scaffolding component 400.
[0049] The main keel 200 and secondary keel 300 are made of square steel pipes. Square steel pipes have a regular cross-sectional shape and a larger moment of inertia, which can withstand greater loads. That is, in the construction of beam structure formwork with the same cross-section, the spacing of the main keel of square steel pipes is much smaller than that of round steel pipes, and there is no need to add beam support poles under small and medium-sized structural beams, which can save installation time and material input.
[0050] The following is a brief explanation of the operation steps for the beam support system:
[0051] When using it, first mark the elevation line of the bottom formwork of the beam, calculate the position of the main keel 200 and the secondary keel 300 according to the bottom elevation of the beam, and mark them on the uprights on both sides of the beam. Put the two locking devices 10 on the uprights of the scaffolding component 400, place the main keel 20 between the two locking devices 10, put the clamp 20 on the U-shaped screw 11 and lock it with the nut to fix it, thus completing the installation of the beam support system.
[0052] Compared with the shortcomings and deficiencies of the existing technology, the keel reinforcement component and the beam support system with the component provided by this utility model have a reasonable structure. The guard plate configured in the keel reinforcement component increases the contact area of the components, and the pad increases the friction between the components, thereby ensuring the reliability of the fixation. The main keel and the secondary keel are made of square steel pipes. Square steel pipes have a regular cross-sectional shape and a large moment of inertia, which can withstand greater loads.
[0053] This utility model is not limited to the above-described embodiments. Anyone can derive other products in various forms under the guidance of this utility model. However, regardless of any changes made in its shape or structure, any technical solution that is the same as or similar to this application falls within the protection scope of this utility model.
