Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a precast concrete panel manufacturing method,

The present invention relates to a method of manufacturing a precast concrete panel and a shim block, which is a fixture for fixing and fixing the door frame to the inner space of the door frame for installation on the door frame.

When constructing a building using a precast concrete panel (hereinafter referred to as "panel") as a wall, a door frame must be installed on such a wall when such a wall is provided with a door. Thus, Japanese Patent No. 10-1376407 discloses a panel body having an opening formed therein for inserting and fixing the window frame; A joint protrusion formed on the upper end of the body so as to be protruded and embedded with a plurality of reinforcing bar sleeves; A joint groove formed in the lower end of the body so as to be recessed and protruded in a plurality of vertical reinforcing bars; A plurality of reinforcing bars for slab joining protruding from an upper end of a rear surface of the body so as to be joined to a reinforcing bar to be joined to the field striking concrete slab; And a plurality of wall joining reinforcing bars projecting laterally from both sides of the body or from both sides of the body to the rear of the body to increase the joining force between the body and the concrete slab.

 However, such a wall has a drawback that the effect of insulation is small, and a styrofoam plate for insulation is installed inside the wall. However, when the styrofoam is installed inside the wall, it is not easy to fix the door frame to the inner circumferential surface of the space of the wall for installing the door frame.

Thus, in a conventional utility model registration No. 20-0478749, styrofoam, which is a heat insulating material, is inserted in the middle of a panel at the time of manufacturing the panel, and a door fastener for fixing the door frame to the styrofoam panel end portion on the inner circumferential surface side Wherein the frame fastener comprises a body of a rectangular parallelepiped shape made of plastic;

A plurality of fixing pins protruding from a lower portion of the body;

Wherein the panel is formed by inserting concrete into both sides of the styrofoam by inserting the fixing member into the end of the styrofoam in the door frame direction, The fixing frame is fixed to the styrofoam so that the door frame can be fixed to the styrofoam while the panel is placed on the styrofoam. However, since such a fastener is installed on the edge of the styrofoam with a shallow thickness, the degree of engagement is low, so that there is a large risk that the reinforcing bars will be dislocated in the concrete pouring process, In particular, such a fixture is provided in the fixture 400, as shown in FIG. 3 of the Utility Model Registration No. 20-0478749, in particular, The styrofoam panel 110 is dislocated by the force of the screw or the force of the hammer and the styrofoam panel 110 is pushed inward to be caught in the fixture 400 220) is not appropriate.

Further, in the above-mentioned Utility Model Registration No. 20-0478749, when the fixing pin is molded from the injection mold for molding, the fixing pin must be injected in the longitudinal direction of the fixing pin so that the fixing pin having a long length at the time of injection is bent There is a drawback that the fixture can not maintain the correct position when the fixture is put on the styrofoam.

Accordingly, it is an object of the present invention to provide a panel assembly for a panel, which can prevent the fixture, which is stuck to the styrofoam panel, from escaping out of the panel, A method of manufacturing a panel in which a styrofoam is broken by the force of a hammer applied to the nail and is prevented from being pushed inward, and a fixture used in the method are to be provided. Further, the present invention is intended to solve the problem that the fixing pin is not bent when injecting the fixing member, so that the fixing member does not deviate from the correct position when the fixing member is put on the styrofoam.
