[0025] The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments. It should be noted that the embodiments of the present invention and the features in the embodiments can be combined with each other without conflict. For the convenience of description, if the words "upper", "lower", "left" and "right" appear in the following, they only indicate that the upper, lower, left and right directions are consistent with the drawings themselves, and do not limit the structure.

[0026] like Figure 1 , Figure 2As shown, a copper bar embedded concrete equipment foundation provided in this embodiment includes a main body 1, a bottom layer 3 coated on the outer surface of the main body 1 and a plaster layer 4 coated on the outer surface of the bottom layer 3, the bottom of the main body 1 has a first corner 11, the top of the main body 1 has a second corner 12, copper bars 2 are embedded at the first corner 11 and the second corner 12, the copper bars 2 are attached to the plaster layer 4, and the outer surface of the plaster layer 4 is provided with a finishing layer 5 flush with the copper bars 2.

[0027] In one embodiment, the body 1 is cylindrical, the bottom of the body 1 has a first corner 11, the top of the body 1 has a second corner 12, and the first corner 11 and the second corner 12 are both embedded with copper bars 2.

[0028] In another embodiment, the body 1 is a square column. In addition to the first corners 11 and the second corners 12 described above, a third corner 13 is provided between the vertical side walls of the square column, and the copper bar 2 is embedded in the third corner 13 .

[0029] The copper strip 2 is L-shaped with a corner, which is adapted to the corresponding corner. The copper strip 2 is attached to the plaster layer 4, and the outer surface of the plaster layer 4 is provided with a plaster layer 5 flush with the copper strip 2. The outer surface of the plaster layer 5 and the copper strip 2 is provided with a cement layer.

[0030] The present invention also provides a construction method for the above-mentioned copper strip embedded concrete equipment foundation, including the following steps: concrete foundation construction → cleaning the base layer (keeping it clean) → slurry throwing with glue and cement slurry → two layers of cement mortar (cement: sand: water = 1:2.5:0.4) → copper strip corner protection installation → surface polishing 2 to 3 times (after initial setting and before final setting) → brushing 1 mm pure cement slurry on the surface.

[0031] The specific steps include:

[0032] 1) pouring concrete to form a body 1 of the foundation;

[0033] 2) After the construction of the main body 1 is completed, the surface of the equipment foundation is cleaned and roughened to ensure that there is no water accumulation, slag accumulation or debris on the surface, and finally the bottom layer 3 is formed;

[0034] 3) Construction of plaster layer 4, glue cement slurry slurry: layered construction cement mortar painting construction, cement mortar ratio: cement: sand: water = 1:2.5:0.4, make ash cakes before painting (ash cakes are cement blocks used to control the building elevation and the flatness and verticality of the wall when plasterers paint or pouring the floor), make plastering thickness at each point according to the foundation conditions to control the ash cakes, and make vertical ribs according to the ash cakes. When decorating the building, the wall plastering area is large. Before plastering, use mortar to make small ash cakes (also called dotting) on ​​the wall at a certain interval, and then continue to use mortar to make one or several ash bars (generally the interval is not more than 1.5m) along the vertical and horizontal directions of the small ash cakes to control the plastering thickness and flatness. The top surface of the main body 1 of the equipment foundation is sloped as required (slopeing refers to building a certain gentle slope in the designed drainage direction to guide the rainwater on the roof in an organized manner to the rainwater drainage system of the building and the city. This method of forming the roof slope is called building slope, material slope or pad slope), with a smooth slope and no water accumulation; if the equipment foundation has an arc, ensure that the plastering thickness of each plane within the arc range is consistent. Cement mortar is constructed in two layers to prevent cracking caused by excessive thickness in one construction. When constructing each layer of plastering, use a wooden trowel to fully compact, rub and flatten the mortar;

[0035] 4) The copper strip 2 is embedded in each corner of the body 1. The end cut of the copper strip 2 should be flat, the copper strip 2 should be installed firmly and straight, the splicing should be tight, and the arc part should be bent before embedding;

[0036] 5) Construction of the surface layer 5, the surface mortar is applied and compacted with a wooden trowel, and then a special mold is used to shape and trim the surface and finish the surface. After the surface mortar is cured, the surface should be flat and without indentations, the corners should be square and straight, and the arcs should be consistent. After the painting is completed, watering or covering should be carried out in time for maintenance;

[0037] 6) After the surface layer is constructed and finished, pour 1mm pure cement slurry and protect the finished product of the clear water surface. Cover it with film, woven cloth or building blanket to prevent permanent defects caused by pollution, scratches and damage.

[0038] The above descriptions are merely embodiments of the present invention and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
