Description

(54) BILL DETAIL

one

The invention relates to the construction and can be used as embedded parts of columns, beams, wall panels and other concrete and reinforced concrete building structures.

A known embedded part is made 5 in the form of a plate, to which a pipe is welded to the end with coaxial holes 1 made in its walls.

The disadvantage of this embedded part is high metal intensity.

Closest to the invention is an inset piece, including a plate and anchor rods welded to it under a flux layer or contact relief welding 2.

The disadvantage of this detail also lies in the high metal intensity.

The purpose of the invention is to reduce the metal consumption of the embedded part.

The goal is achieved by the fact that in the inset, which includes a steel plate 20 and anchor rods welded to it from the ends of reinforcing steel, plastic Tjina, there is a spherical protrusion at the welding points of each rod, while around the base of the rod there is a rim of weld metal.

FIG. 1 shows the proposed mortgage detail, a general view; On Phi 2 and 3 - options for welding the rod to the plate.

The embedded part is made of plate 1 and anchor rods 2, which are connected to the plate by submerged arc welding. As a result, a hard section is created at the welding site, in which the protrusion 3 in the upper or lower part is fused completely with the rim of the directional metal 4, which creates more favorable conditions for the joint operation of the plate and the anchors. All this allows to reduce the thickness of the plate.

It is also possible to weld with the penetration of a spherical protrusion (Fig. 1) and filling the cavity with the molten metal.

In the embedded part (Fig. 2), welding is performed along the cavity, and in the part (Fig. 3), an inclined arrangement of the anchor rods is shown.

Claims (2)

Claim A embedded part, including a steel plate and butt welded reinforcing steel anchor rods, characterized in that, in order to reduce the metal consumption, the plate has spherical protrusions in the places of welding of each rod, while a corolla made of metal deposited during welding is formed around the base of the rod. 5 Sources of information taken into account in the examination 1.
