Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

The foam embedded anchor box shown in the drawings 1-6 comprises a supporting block 1, wherein the supporting block 1 is made of stainless steel materials, a shell 2 is arranged on the upper surface of the supporting block 1, the supporting block 1 can be cuboid or cylindrical, as long as the supporting block 1 can support the shell 2, a scraping plate 7 is fixedly connected to the upper surface of the shell 2 through glue, a handle 8 is arranged on the surface of the scraping plate 7, the shell 2 is made of polystyrene foam, a locking bolt 9 is connected to the surface of the supporting block 1 in a threaded manner, a mounting groove is formed in the supporting block 1, a base plate 11 is arranged on the inner wall of the mounting groove, and dismounting mechanisms are arranged on the surfaces of the supporting block 1 and the shell 2;

The dismounting mechanism comprises grooves formed in the surfaces of the supporting block 1 and the shell 2, the backing plate 11 is made of elastic rubber, and grooves for the threaded reinforcing steel bars to pass through are formed in the surfaces of the supporting block 1 and the shell 2.

The diameter of recess is about to be greater than the diameter of twisted steel to guarantee that the twisted steel can get into inside casing 2, the surface of supporting shoe 1 passes through glue fixedly connected with quick detach board 3, the fixed surface of quick detach board 3 is connected with handle 10, quick detach board 3 is made by aluminum alloy material, the surface of quick detach board 3 is provided with round bar 4, the surface of round bar 4 is provided with a plurality of barb 5, because the surface of round bar 4 is provided with a plurality of barb 5, consequently when pulling quick detach board 3, the barb 5 on the round bar 4 can pull out most foam casing 2, in order to conveniently demolish casing 2.

This pre-buried anchor box of foam is through setting up casing 2, scraper blade 7, quick detach board 3 and handle 10, because casing 2 is made by the polystyrene foam, at the job site, only need just to make the anchor box to the simple cutting drilling of foam board to the anchor box quality that makes is light, when demolishing casing 2, because quick detach board 3 is fixed on casing 2 inner wall, only need the power pulling quick detach board 3 can drag down the foam casing 2 that attaches most on the concrete when demolishing, and remaining part foam casing 2, then can strike off it with scraper blade 7, and then can reach the purpose of conveniently demolishing.
