[0002] Formwork support is a temporary support structure set up during the construction process to ensure the concrete pouring and structural stability. It is mainly used for cast-in-place concrete roof slabs, wall panels, columns, beams, etc. It helps to ensure the shape and size of the concrete structure and improve construction efficiency and quality. When supporting the top slab, it is necessary to use the main and secondary keels to reinforce the top slab in an alternating manner, and then use vertical poles and jacking supports to support the keels.

[0003] However, in the process of implementing relevant technical solutions, it was found that at least the following technical problems exist: when using top supports to support the keels, there is often an offset between the overlap position of the main keels and the connection between the top supports of the support system, causing the front and rear main keels and the support system to be offset, resulting in deviations in the force applied to the formwork support system, affecting the support effect on the formwork. Utility Model Content

[0004] The present application solves the problem of easy deviation at the keel overlap in the prior art by providing a main keel connection and fixing device suitable for a formwork support system, thereby achieving the effect of limiting the keel overlap.

[0006] Furthermore, the limit assembly includes: two threaded rods, which are respectively threadedly connected to the middle part of one side of the two side panels; a knob, which is fixedly provided with one end of the threaded rod away from the middle part of the bottom plate; and a clamping plate, which is rotatably connected to one end of the threaded rod, and one side of the clamping plate is in contact with the main keel.

[0007] Furthermore, limiting rods are fixedly provided at both ends of the clamping plate away from the middle portion of the bottom plate, and the two limiting rods are interlaced and connected with the side plates.

[0008] Furthermore, a scale plate is fixedly arranged on the limit rod.

[0010] The technical solution provided by this application has at least the following technical effects or advantages:

[0011] By fixing the Japanese-shaped side plates and reinforcing ribs in the middle of the top support, the two sections of the main purlins can be aligned at the reinforcing ribs. The clamping plates on both sides are moved toward the main purlin by rotating the threaded rod, and the main purlins of different sizes can be limited. By observing the scales on the limiting rods on both sides, it can be ensured that the two sections of the main purlins are in the middle position of the reinforcing ribs, thereby preventing deviations at the overlaps of the main purlins and improving the stability of the formwork support.

DETAILED DESCRIPTION

[0016] The embodiment of the present application discloses a main keel connection and fixing device suitable for a formwork support system, wherein the rotation of a threaded rod 61 drives two clamping plates 63 to clamp and limit the main keel 30, and the scale displayed on the scale plate 65 on the limit rod 64 determines that the two main keels 30 are both located in the middle between the two side plates 50, so that the two sections of the main keel 30 can be aligned together on the top support 10, preventing the overlap of the main keel 30 from being offset, thereby improving the stability of the formwork support.

[0017] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

The reinforcing rib 80 and the two side plates 50 are in the shape of a Chinese character 'Ri'. Both sides of the reinforcing rib 80 are provided with main keels 30. Both of the two main keels 30 are arranged between the two side plates 50. Both ends of the two side plates 50 are provided with limiting components 60 for fixing the two main keels 30. By inserting the main keels 30 between the two side plates 50, the two sections of the main keels 30 are aligned between the two side plates 50, preventing the overlapping position of the two sections of the main keels 30 from shifting, so that the force on the top of the jack 10 and the vertical rod 20 will not deviate, and improving the stability of supporting the formwork.

[0019] Please refer to Figure 1 , Figure 2 and Figure 3 , a fixing component 70 is arranged on the top of the reinforcing rib 80. A threaded groove 90 is opened in the middle of the top of the jack 10. The fixing component 70 includes a bolt 71 and a gasket 72. The bolt 71 is movably connected to the inside of the reinforcing rib 80. Through holes are opened in the middle of the bottom plate 40 and the reinforcing rib 80. The bolt 71 is arranged inside the through hole, and the bottom of the bolt 71 is threadedly connected to the threaded groove 90. The gasket 72 is arranged on the outside of the bolt 71, and the gasket 72 is in contact connection with the top of the reinforcing rib 80. The gasket 72 can increase the bearing area of the bolt 71 on the surface of the reinforcing rib 80 and can also prevent the bolt 71 from loosening. By screwing the bolt 71 into the inside of the threaded groove 90, the reinforcing rib 80 can be installed on the jack 10. The reinforcing rib 80 is located in the middle position of the jack 10, so that the main keels 30 on both sides of the reinforcing rib 80 are aligned in the middle position of the jack 10. The overlapping part of the two main keels 30 is located in the middle of the jack 10, so that the jack 10 can stably support the two main keels 30, preventing the force on the jack 10 from deviating and affecting the stability of the formwork support.

The clamping plate 63 is rotatably connected to one end of the threaded rod 61, and one side of the clamping plate 63 is in contact with the main keel 30. The two limiting rods 64 are respectively fixedly provided at the two ends of the side of the clamping plate 63 away from the middle of the bottom plate 40. The two limiting rods 64 are interlaced with the side panels 50. The scale plate 65 is provided on the limiting rods 64. Through the interlaced connection between the two limiting rods 64 and the side panels 50, The clamping plate 63 will not rotate with the threaded rod 61, and the movement of the clamping plate 63 is limited, so that the rotation of the knob 62 and the threaded rod 61 can drive the clamping plate 63 to move toward the main keel 30. The clamping plates 63 on both sides can limit the main keel 30, and main keels 30 of different sizes can be fixed between the two side panels 50, thereby improving the applicability of the fixing device. By observing the scale of the scale plate 65 on the limiting rod 64, the main keel 30 can be fixed in the middle position between the two side panels 50, so that the two sections of the main keel 30 can be aligned in the middle of the reinforcing rib 80, thereby preventing the two sections of the main keel 30 from offsetting, thereby improving the stability of the formwork support.
