[0023] Please refer to Figures 1-3 , the present utility model provides a technical solution:

[0024] An adjustable support device for the cage of the collar beam, comprising a steel base 1 and a screw rod column 2. The steel base 1 includes a thin steel plate 101 and connecting ear plates 102. The connecting ear plates 102 are welded at the front end, rear end, and the centers on both sides of the thin steel plate 101. A screw rod column 2 is welded at the center of the top of the thin steel plate 101. Two first disk buckle connectors 4 are sleeved on the surface of the screw rod column 2. Nuts 3 are respectively arranged at the top and bottom of the two first disk buckle connectors 4, and the four nuts 3 are sleeved on the screw rod column 2.

[0025] A second disk buckle connector 5 is arranged on the inner side of the outer surface of the first disk buckle connector 4. The first disk buckle connector 4 and the second disk buckle connector 5 are fixed by a disk buckle pin 7. There are two screw rod columns 2. A cross brace steel pipe 6 is arranged between the two second disk buckle connectors 5 on the same horizontal plane. The two second disk buckle connectors 5 and the cross brace steel pipe 6 are combined into a transverse support structure, and the two transverse support structures support the reinforcement cage 8.

[0026] Further, holes 401 are opened on the outer sides of the top and bottom of the first disk buckle connector 4, and the screw rod column 2 is arranged inside the holes 401.

[0027] Further, hole grooves 402 are arranged at the top and bottom of the first disk buckle connector 4. A groove is opened in the middle of the outer side of the second disk buckle connector 5. The first disk buckle connector 4 is arranged at the groove. Fixing grooves are opened through at the top and bottom of the groove of the second disk buckle connector 5 and corresponding to the hole grooves 402.

[0028] Furthermore, the hole groove 402 and the fixing groove are connected by a button-and-plug nail 7.

[0029] Specifically, the screw rod column 2 can be made of screw rods of different lengths used for building scaffolding, and its size can be selected according to the need to support the steel reinforcement cage. Figure 1 As shown, it is 1500 mm.

[0030] The bottom surface size of the thin steel plate is generally selected as 50 mm × 1000 mm, and the thickness ranges from the thinnest to the thickest, from 5 mm to 15 mm, as Figure 3 shown. The connection method with the screw rod column 2 is welding.

[0031] The transverse support structure formed by the second button-and-plug connection member 5 and the cross brace steel pipe 6 can generally be made of materials for scaffolding, or other steel pipes can be welded to the button-and-plug connection member 5.

[0032] It can be seen from this that the structure of the present utility model is simple, convenient for installation and adjustment, and convenient for obtaining materials for production.

[0033] Furthermore, a fixing cone 9 is arranged inside the connecting ear plate 102. The bottom of the fixing cone 9 is located in the soil, and the bottom of the thin steel plate 101 is in contact with the top of the mud surface. From this, it can be obtained that when supporting the vertical support structure, the thin steel plate 101 of the steel base 1 is placed into the mud surface, and then a fixing cone 9 with a matching diameter is inserted into the opening of the connecting ear plate 102, so that the steel base 1 can be better fixed and fixed into the soil, which is beneficial for support.

[0034] Working principle:

[0035] Step S1: Stand the vertical support structure formed by combining two screw rod columns 2 and the steel base 1 on both sides of the steel reinforcement cage 8 to be supported.

[0036] Step S2: Use the nut 3 to adjust the two first button-and-plug connection members 4 on the screw rod column 2 to an appropriate height and angle.

[0037] Step S3: Connect and fix the transverse support structure formed by combining the second button-and-plug connection member 5 and the cross brace steel pipe 6 with the vertical support structures on both sides into a whole with button-and-plug nails 7.

[0038] Step S4: Use a wrench to adjust the height of the nut 3 so that the transverse support structure is tightly connected to the steel reinforcement cage 8 to be supported.

[0039] Step S5: Tighten the upper nuts of each first button-and-plug connection member 4 to fix the position of the first button-and-plug connection member 4.

[0040] The specific adjustment means in step S4 are as follows: First, loosen the upper nuts 3 of each first disk buckle connecting member 4, and then use tools such as a wrench to drive the first disk buckle connecting member 4 by turning the lower nut of the first disk buckle connecting member 4 to lift the transverse support structure or bring it into close contact with the steel reinforcement cage 8, so that the steel reinforcement cage 8 is maintained at a predetermined position.

[0041] An adjustable support device for the steel reinforcement cage of a collar beam according to the present invention can adjust the height of the transverse support structure, is applicable to foundation pits and steel reinforcement cages 8 of different sizes and depths, and provides uniform and stable support, effectively preventing the vertical deformation of the steel reinforcement cage 8 before pouring.
