[0008] The reinforcement structure is installed at the weld joint of the two frame bodies to improve the compressive strength of the weld joint. The reinforcement structure includes: load-bearing blocks, clamping plates, retaining strips, top covers, and retaining plates. The load-bearing blocks are clamped at the corners of the two frame bodies. The clamping plates are symmetrically fixed to the front and rear walls of the load-bearing blocks. The retaining strips are fixed to the walls of each clamping plate. The top cover slides on the top of the upper frame body. The retaining plates are symmetrically fixed to the walls of the load-bearing blocks.

[0009] In a preferred embodiment of this utility model, the load-bearing block is a right-angled triangular block, the clamping plate is an arrow-shaped plate, the clamping plate is obliquely placed on the wall of the load-bearing block, the clip is a rectangular rod, the clip is horizontal on the wall of the clamping plate, and the symmetrical clamping plate spacing can be adapted to the width of the frame.

The slot is a straight groove, and the symmetrical slots can engage with the corresponding slot strips. The adhesive groove is a triangular groove, and each adhesive groove can fit against the side wall of the corresponding clamping plate.

[0013] In a preferred embodiment of this utility model, the bottom of the load-bearing block is further provided with a reinforcing structure, which includes a screw cylinder, a screw plate and a screw rod.

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model.

[0027] like Figure 1 As shown, a keel frame reinforcement connection device includes: a frame body 20, which is a conventional keel frame. One end of the frame body 20 is welded to another identical frame body 20. The two frame bodies 20 are L-shaped. This is existing technology, so it will not be described in detail here.

[0028] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, a reinforcement structure is installed at the weld joint of the two frame bodies 20 to improve the compressive strength of the weld joint. The reinforcement structure includes: load-bearing blocks 30, clamping plates 31, retaining strips 32, top covers 33, and retaining plates 34. The load-bearing blocks 30 are clamped at the corners of the two frame bodies 20. The clamping plates 31 are symmetrically fixed to the front and rear walls of the load-bearing blocks 30. The retaining strips 32 are fixed to the walls of each clamping plate 31. The top covers 33 slide on the top of the upper frame body 20. The retaining plates 34 are symmetrically fixed to the walls of the load-bearing blocks 30.

[0029] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, the load-bearing block 30 is a right-angled triangular block, the clamping plate 31 is an arrow-shaped plate, and the clamping plate 31 is obliquely placed on the wall of the load-bearing block 30. The clamping strip 32 is a rectangular rod, and the clamping strip 32 is horizontal on the wall of the clamping plate 31. The symmetrical clamping plate 31 is spaced to fit the width of the frame 20. The top cover 33 is a rectangular plate, and the retaining plate 34 is a right-angled trapezoidal plate. The bottom of the top cover 33 can fit against the top of the frame 20 above. The reinforcement structure also includes a base plate 35, a slot 36, and a mounting groove 37. The base plate 35 is fixedly connected to the bottom of each retaining plate 34. The slot 36 is opened on the side wall of each retaining plate 34, and the mounting groove 37 is opened on the symmetrical retaining plates. The walls 34 face each other. The base plate 35 is rectangular and can fit against the wall of the frame 20 below. The slot 36 is a straight slot and the symmetrical slots 36 can engage with the corresponding slot strips 32. The groove 37 is triangular and can fit against the side wall of the corresponding clamping plate 31. The bottom of the load-bearing block 30 is also provided with a reinforcement structure, which includes a screw cylinder 38, a screw plate 39 and a screw rod 40. The screw cylinder 38 is fixedly connected to the inclined surface below the load-bearing block 30. The screw plate 39 is fixedly connected to the bottom inclined surface of each clamping plate 34. The screw rod 40 is threadedly connected to the wall of the screw plate 39.

[0030] In practical use, after the welding of the two frame bodies 20 is completed, the top and the inclined side of the load-bearing block 30 are first attached to the corners of the bottom of the two frame bodies 20 respectively, and the frame bodies 20 are attached between the symmetrical clamping plates 31. At this time, the clamping strip 32 will be in a horizontal state. Then, the bottom of the top cover 33 is attached to the top of the frame body 20 above and slides towards the clamping plate 31. After the clamping groove 36 on the wall of the clamping plate 34 is fully attached and snapped from the side wall of the clamping strip 32, the wall of the clamping plate 31 facing the groove 37 will be fully attached to the groove 37. At this time, the symmetrical clamping plates 31 will be located between the symmetrical clamping plates 34, and the top of the bottom plate 35 will contact the bottom of the clamping plate 31. The bottom plate 35 will also be attached to the wall of the frame body 20.

[0031] In summary, by setting up a reinforced structure and combining the upper and lower parts, the compressive strength of the connection between the two frame bodies 20 can be improved, while also enabling rapid assembly. The entire assembly process can be achieved by using a screwdriver to tighten the screws 40 and align the load-bearing blocks 30 and the top cover 33. Compared with the solution of welding steel plates, this reduces costs and allows for faster reinforcement and installation.

[0032] like Figure 5 As shown, the screw barrel 38 is a rod with a semi-capsule-shaped cross section, and the screw plate 39 is a semi-capsule-shaped plate. The walls of the screw barrel 38 and the screw plate 39 are provided with threaded grooves that are adapted to the screw 40. The threaded grooves on the wall of the screw barrel 38 can coincide with the threaded grooves on the wall of the screw plate 39.

[0033] In practical use, when the threaded groove on the wall of the symmetrical screw plate 39 coincides with the threaded groove on the wall of the screw barrel 38, screw the screw 40 into the coinciding threaded groove.

[0034] In summary, by setting up a reinforcing structure to simultaneously fix the positions of the top cover 33 and the load-bearing block 30 by limiting the positions of the overlapping screw cylinder 38 and screw plate 39, the disintegration of the top cover 33 and the load-bearing block 30 is prevented, thereby improving the stability of the device.

[0035] Working principle: After the welding of the two frame bodies 20 is completed, the top and side wall slopes of the load-bearing block 30 are first attached to the corners at the bottom of the two frame bodies 20, and the frame bodies 20 are attached between the symmetrical clamping plates 31. At this time, the retaining strip 32 will be in a horizontal state. Then, the slidable I-shaped plate installed on the side wall of the top cover 33 is pushed upward, and then the bottom of the top cover 33 is attached to the top of the upper frame body 20 and slid towards the clamping plate 31. The I-shaped plate slides in the rectangular groove opened in the wall of the top cover 33, and then the retaining plate 34 is clamped in the groove 36 on the wall. After the clip 32 is fully engaged with the side wall, the side of the clamp 31 facing the groove 37 will be fully engaged with the groove 37. At this time, the symmetrical clamp 31 will be located between the symmetrical clamping plates 34, and the top of the bottom plate 35 will contact the bottom of the clamp 31. The bottom plate 35 will also be engaged with the wall of the frame 20. At this time, the thread groove of the symmetrical screw plate 39 will coincide with the thread groove of the screw barrel 38. At the same time, the I-shaped plate on the side wall of the top cover 33 will slide down to be engaged with the side of the frame 20. At this time, the screw 40 can be screwed in from the overlapping thread groove.
