する。 Conventionally, as shown in Fig. 1, a concrete frame 1
When the embedded metal fitting 2 is buried in the embedded metal fitting 2 and the mounting fittings 3 and jigs for piping, air conditioning machines, other equipment, etc. are welded to the embedded metal fitting 2, the embedded metal fitting 2 expands due to the welding heat. Cracks and peeling occur in the surrounding concrete area.

係るものである。 The present invention has been proposed in order to solve these problems, and includes a structure in which a groove is provided on the surface of a concrete structure frame along the periphery of an embedded metal object buried in the frame body. The present invention relates to a mounting structure for embedded metal fittings in a concrete structure.

割れ、剥離を防止しうるものである。 In the present invention, as described above, a groove is provided on the surface of the concrete body along the periphery of the metal piece embedded in the concrete body, so the presence of the groove allows the metal piece to be buried. It can expand freely, relieves the thermal stress caused by welding, and prevents cracking and peeling of concrete.
以下本発明を図示の実施例について説明する。 The present invention will be described below with reference to the illustrated embodiments.

ト躯体１１の表面に凹溝を設けるものである。 As shown in FIGS. 2 and 3, when embedding the embedded metal fitting 12 in the concrete frame 11, a foamed polystyrene material with the same thickness as the metal fitting 12 and a width of 5 to 10 mm is placed around the buried part of the embedded metal fitting 12. 13 etc. are fixed to the formwork 14 so as not to move during concrete pouring,
After concrete placement, the styrofoam material 13
is removed and grooves are provided on the surface of the concrete body 11 along the periphery of the embedded hardware 12.
従つて前記凹溝によつて埋込金物１２は溶接時
において自由に膨脹し、溶接熱による応力が緩和

A concave groove 15 having a thickness equivalent to the thickness is bored.
