[0041] The utility model is further described in detail below with reference to the accompanying drawings and specific implementation methods:

[0042] Example 1. This example aims to provide an F-type high-strength concrete pad, which is mainly used to ensure the thickness of the concrete protective layer. In view of the problems that the existing concrete pads have low strength, are easy to break, have a large demand for pads, and cannot guarantee the thickness of the upper concrete and the thickness of the plate, this example provides an F-type high-strength concrete pad.

[0043] like Figure 1-3 As shown in the figure, an F-type high-strength concrete pad includes: a main support platform, a side support platform and a fastening nut 14; the main support platform includes a main connection part 1 and a main hanging part; the main connection part 1 and the main hanging part are connected by an integrated molding; the main connection part 1 is a regular quadrangular prism structure, and a vertical slot 4 is opened on the front side, rear side and right side of the main connection part 1, and the slot 4 is a dovetail groove; a threaded head is arranged on the top of the main connection part 1, and the threaded head 5 is pre-buried in the top of the main connection part 1 when casting the pad.

[0044] The main hanging part includes a main upper hanging platform 2 and a main lower hanging platform 3. The main upper hanging platform 2 is provided with a main upper clamping groove 10, and the main lower hanging platform 2 is provided with a main lower clamping groove 11. The main upper clamping groove 10 and the main lower clamping groove 11 are arc grooves, and the arc center axes are parallel; the main upper clamping groove 10 and the main lower clamping groove 11 can both clamp a steel bar, and the main upper hanging platform 2 and the main lower hanging platform 3 are fixed at intervals on the left side of the main connecting part 1. When prefabricating the main supporting platform, the distance between the two steel bars can be changed by changing the positions of the main upper hanging platform 2 and the main lower hanging platform 3 on the main connecting part 1. At the same time, the distance from the upper end face of the main upper hanging platform 2 to the upper end face of the main connecting part 1 is the thickness of the upper skin concrete, and the distance from the upper end face of the main lower hanging platform 3 to the lower end face of the main connecting part 1 is the thickness of the lower skin concrete.

[0045] The side support platform includes a secondary connection part 6 and a secondary hanging part; the secondary connection part 6 is also a regular quadrangular prism structure, the secondary connection part 6 and the secondary hanging part are integrally formed and connected, and a plug 9 adapted to the slot 4 is arranged on the right side of the secondary connection part 6; the secondary hanging part includes a secondary upper hanging platform 7 and a secondary lower hanging platform 8, the secondary upper hanging platform 7 and the secondary lower hanging platform 8 are respectively arranged on the left side of the secondary connection part 6 at intervals, a secondary upper clamping groove 12 is opened on the secondary upper hanging platform 7, and a secondary lower clamping groove 13 is opened on the secondary lower hanging platform 8, the secondary upper clamping groove 12 and the secondary lower clamping groove 13 are arc grooves, and the arc center axis Parallel; the secondary upper clamping groove 12 and the secondary lower clamping groove 13 can both clamp one steel bar. When prefabricating the side support platform, the height of the secondary upper hanging platform 7 and the secondary lower hanging platform 8 can be arranged according to the height of the main upper hanging platform 2 and the main lower hanging platform 3 of the main support platform to ensure that the steel bars in the main upper clamping groove 10 will not affect the steel bars in the secondary upper clamping groove 12; at the same time, ensure that the steel bars in the main lower clamping groove 11 will not affect the steel bars in the secondary lower clamping groove 13, for example, make the main upper clamping groove 10 higher than the secondary upper clamping groove 12, and the main lower clamping groove 11 higher than the secondary lower clamping groove 13.

[0046] A side support platform is inserted into one side of the main support platform to form an angle support pad, and the fixing nut 14 is threadedly connected to the threaded head 5 so that the fixing nut 14 is mortgaged on the side support platform. The fixing nut 14 can prevent the side support platform from being squeezed out of the slot 4 due to the impact of concrete, thereby ensuring the strength of the support.

[0050] like Figure 5-6As shown in the figure, in this embodiment, a side support platform is respectively inserted into the three slots 4 of the main support platform to form a surface support pad. The surface support pad has a main upper clamping slot 10, a main lower clamping slot 11, three secondary upper clamping slots 12 and three secondary lower clamping slots 13, which can support eight steel bars at one time, greatly reducing the number of pads used and saving costs.

[0051] In order to ensure that the fixing nut 14 can better limit the side support platform, the upper end surface of the main support platform is lower than the upper end surface of the side support platform. When the fixing nut 14 is screwed downward, all the force can be applied to the side support platform, so that the pad as a whole can be more stable, ensuring the supporting effect on the steel bars.
