The present invention relates to a fixing device for a chassis window frame used in the factory production of precast concrete panels to which the chassis window frame is attached in advance. In the field of prefabrication of buildings, it is preferable to precast concrete wall panels pre-attached with chassis windows for high building efficiency than to install such window frames on the walls of buildings on site.

The manufacture of precast concrete panels with pre-attached window frames in this way usually places the chassis windows in contact with several abutments fixed at predetermined locations on the substrate, the base of the mold to which the concrete is to be cast. do.

Next, a holder frame is placed on the upper surface of the chassis window frame and pressed to bring the window frame into full contact with the substrate.

If the chassis window frame is not pressurized to be in sufficient contact with the substrate in the above-described conventional fixing device, concrete continuously poured into the mold is introduced into the chassis window frame from the gap between the substrate and the chassis window frame.

However, if an excessive force is applied on the chassis window frame, the wall portion of the chassis window frame arranged perpendicular to the substrate is bent inward or outward depending on the position of the holder frame with respect to the chassis window and the cross-sectional shape of the chassis window frame.

It is therefore a general object of the present invention to provide a device for securely but removably securing a chassis window frame or similar panel assembly at a location within a mold in manufacturing a concrete panel with a window frame pre-attached.

A special object of the present invention is to provide a fixing device that can prevent the concrete from entering the inside of the window frame without applying a strong pressure enough to deform the window frame.

In short, the fixture of the present invention includes a plurality of pedestals fixed at predetermined locations on a mold substrate for pouring concrete to produce precast concrete panels. A chassis window or an analog thereof pre-attached in the concrete panel is placed on the mold's substrate with the pedestals positioned inside the window frame in contact with the window frame. Bracing rods secure the window frame to each pedestal in an easily removable way. The holder frame is positioned on the chassis window frame to press the window frame in full contact with the substrate of the mold. Therefore, even if the window frame is in close contact with the substrate of the mold so as to apply a force large enough to prevent the concrete from flowing into the inside of the window frame, the window frame is fixed to the pedestal by the support bar, so that it does not bend as conventionally. Concrete panels manufactured in this way are excellent in appearance and chassis windows or the like can be easily fitted into window frames pre-attached in the panels.

The originality of the present invention and the functions, additional objects and advantages of the respective parts will be readily understood from the following detailed description with reference to the drawings.

The manufacturing of the precast concrete wall panel to which the window frame of the sliding window of the present invention is attached in advance will be described in more detail.

In Figures 1, 2 and 3, the number "10" is a mold holding the concrete 11 in the form of the required wall panel.

The mold 10 is composed of four side panels 12 arranged in a square on the substrate 13.

At a predetermined position on the substrate 13, a plurality of pedestals 14 and 14a arranged inwardly of the window frame are firmly fixed to contact the rectangular window frame of the window. The window frame is shown in Figures 2 and 3 by the garment frame 15 and the base frame 15a. The line frames of the window frames are not marked because they can be fixed in place in the same way as the clothes frame 15.

The fasteners used for the garment frame 15 are described in particular in figures 3 and 4. One or more pedestals 14 arranged inwardly of the clothes frame 15 are provided with grooves 16 vertically downward from the top of the clothes frame 15. The support rod 17 is accommodated in the groove 16, and the support rod has a screw portion 18 at one end and a neck portion 19 cut off at the adjacent portion at the other end.

The threaded portion 18 of the support rod 17 is arranged perpendicularly to the substrate 13 and through holes 20 formed in the upper wall portion 21 which are positioned horizontally when joining the finished wall panel to the building. It protrudes outward from the clothes frame 15. The cap or nut 22 has a female threaded hole for receiving the threaded portion 18 of the support membrane 17 protruding outward of the hole 20 in the upper wall portion 21. The wedge 23 is split into two branches at one end so as to be sandwiched between the pedestal 14 and the above-described neck portion of the support rod over both sides of the neck portion 19 of the support rod 17.

The clothes frame 15 of the window frame is thus fixed in position and is forced toward the pedestal 14 by the horizontal support rod 17.

On the other hand, in the case of the base 15a, it is fixed to the base 14a which supports the supporting rod 17a by the bolt 24 or similar fixture. The support rod 17a extends toward the base 15a to engage the flange 25 in the recess 25 of the support rod 17a on one of the pair of bottom rails 26, the bottom rail 26 being a window. It is formed in the longitudinal direction on the lower wall portion 27 at parallel intervals so as to be used as a chassis rail.

Next, generally a rectangular holder frame 28 is placed on the window frame. The holder frame 28 includes ear straps 29 arranged obliquely adjacent four corners thereof, and bolts 30 or similar fasteners penetrate the ear holders 29 on the substrate 13. It is inserted into a short column 31 which is firmly fixed in place. In this way, the holder frame 28 presses against the window frame and the window frame again presses against the substrate so that it is completely in contact with the substrate 13.

The above-described fixing device of the present invention fixes the window frame of the window and door in place in the mold 10 using the fixing device, and then pours the concrete 11 into the mold to fill the space defined by the window frame.

As pointed out above, the holder frame 28 for pressing the window frame has the upper and lower wall portions 21 and 27 of the garment frame 15 and the base frame 15a and the corresponding wall portions of the unshown line frame as indicated by the dotted lines in Fig. 3. Exert force to warp.

However, they do not bend because the upper and lower wall portions 21, 27, and the like are fixed to the pedestals 14 and 14a by the supporting rods 17 and 17a.

When the concrete hardens, the holder frame 28 is first removed from the window frame by loosening the bolt 30.

The support rod 17 can be removed by first removing the wedge 23 and then loosening the cap 22, while the support rod 17a can be removed simply by loosening the bolt 24.
