[0015] The technical solution of the utility model is described in detail below with reference to the accompanying drawings, but the protection scope of the utility model is not limited to the embodiments.
[0016] Reference Figures 1 to 4The utility model discloses a grounding flat iron used for the foundation of plain concrete equipment, which ensures that the pre-buried grounding flat iron is formed together with the plain concrete at one time, is firm and not easy to be damaged, and the finished end plate mold used for top fixing can be reused to reduce the cost, and specifically comprises an end plate 1, the end plate 1 is provided with a fixing hole 2 and an iron hole 3 which are open at both ends, the specification of the end plate 1 is a galvanized end plate of 140*140*10mm, the end plate 1 is provided with four holes, two of which are fixing holes 2, and the other two are iron holes 3, the specifications of the four holes are all elliptical holes with a length of 50mm and a diameter of 12, wherein the end plate 1 is fixed to the plain concrete template 4 by passing bolts through the fixing holes 2, and the end plate 1 partially extends out of the plain concrete template 4, so that the iron hole 3 can be passed through by the grounding flat iron 5 And it is connected and fixed to the ground. A clamping plate 6 is arranged on both sides of the iron hole 3 on the upper surface of the end plate 1. The width between the two clamping plates 6 is equal to the thickness of the grounding flat iron 5, so that the two clamping plates 6 clamp the grounding flat iron 5. The specification of the clamping plate 6 is a galvanized flat iron of 40mm long and 25*4mm. The clamping plate 6 is welded and fixed on the end plate 1. The clamping plate 6 and the end plate 1 form an end plate mold for installing the grounding flat iron 5. The width of the gap between the two clamping plates 6 is 5mm. A tripod 7 is arranged between the bottom of the grounding flat iron 5 and the ground. The bottom of the grounding flat iron 5 is fixed to the tripod 7 by welding. The tripod 7 includes 3 galvanized round steels with a length of 300mm and φ10. The three galvanized round steels are welded into a three-dimensional triangular structure. The mutually welded parts of the round steels are 100mm each and the curved parts are 100mm.
[0017] The utility model utilizes the principle of a stable three-dimensional triangular structure to use 10# galvanized round steel to fix the vertical embedded grounding flat iron 5 at the bottom, and at the same time uses an end plate 1 commonly used for rooting a bracket to cooperate with two sections of cut and polished 25*4mm flat iron clamping plates 6 to make an end plate mold that can be repeatedly used to fix the vertical grounding flat iron 5 at the top.
[0018] The process of the utility model method is as follows: first, take a 140*140*10 galvanized finished end plate 1 which is commonly used for rooting the bracket, and there are 4 φ12 oval holes (50mm long) on it, and then cut two 140mm long 25*4mm galvanized flat irons, weld them on both sides of the φ12 oval holes as the clamping plate 6, leaving a position for the embedded grounding flat iron 5 to pass through (about 5mm wide) and touch up the paint, then use the end plate mold to fix the upper part of the grounding flat iron 5, and lock the two sides of the end plate 1 on the plain concrete template 4 with bolts, and then cut 3 300mm long (adjusted according to the plain concrete height) 10# round steel strips arc welded into a three-dimensional triangular structure as a tripod 7 and welded to the vertical grounding flat iron 5 as the overall bottom support structure while removing the tumor and touch up the paint, finally after the concrete is poured and solidified, remove the end plate mold and reuse it next time, so far the reinforcement method of the plain concrete foundation embedded grounding flat iron 5 has completed a complete set of construction process flow.
[0019] The utility model can well prevent the grounding flat iron 5 from being completely buried in the poured concrete, and increases the overall firmness between the grounding flat iron 5 and the foundation.
