Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for manufacturing a UT thermal mold material, and more particularly, to an outdoor member and an indoor F1411 member made of gold metal material. This invention relates to a method for connecting heat insulating shapes into one body using a heat insulating connector.

Conventionally, the manufacturing method of this glazed Machi-netsu-type drama was, for example,
7-447'? As described in Japanese Patent Application No. 1, it is produced according to the one-song order shown in FIG. 1 (α) to 0].

That is, as shown in FIG. 1 (cLJ), the outdoor side member 1 and the indoor side member 2 are arranged facing each other, and are connected by a pair of connecting members 3.4 to form a sealed hollow chamber 5 inside. At the same time, each connecting member 3.4 is extruded into a single hollow molded member Af, in which the box-shaped groove 6.7 is completely formed.
As shown in FIG. 1 (cl V !-As shown, a special-shaped thermal plug body jQ is fully press-fitted, with its distal end protruding like an anchor and its proximal end entirely T-shaped.
As shown in FIG. 1 (d+), a heat insulating material 11 is filled into the box-shaped groove 6 in which the insulation cutting part 9 is closed by the base body 1o, and when the heat insulating material 11 is hardened, the other A cutter 8 is attached to the bottom wall of the box-shaped groove 7 as shown in FIG. 1 (=).
The insulation cutting section 12 is opened, and at the same time, this first
As shown in Figures (7) and 5), after closing with a specially shaped blocking body 8, a heat insulating material 11 is filled and hardened to form a heat insulating connection body portion of the heat insulating shape material.

However, the conventional method of manufacturing a heat insulating profile as described above requires the use of a cutter 8 for opening a seven-T thermal cutting section 9.12 in the bottom wall of the box-shaped groove and a heat insulating material 11 to the box-shaped grooves 6, 7. Since the injection port of is provided on the same side and the cutter 8 is placed above, it is not desirable from a safety point of view. It is difficult to carry out sufficient prevention and elimination processes, and there are disadvantages such as deterioration of the working environment and molding of poor-quality insulating joints due to the inclusion of chips, adhesion, etc.On the other hand, the above-mentioned It may be possible to overcome this problem by making the cutter cover, chip removal device, etc. entirely special, but this would not only be expensive but also require more handling, maintenance, and maintenance of the equipment.
Inspection becomes troublesome and the Komagata method is not preferred.

In addition, in order to easily insert the heat insulating base body into the heat insulating cutting part and prevent it from falling off, the tip of the heat insulating base body is made to protrude like an anchor, and the base end
(Since it is a special T-shaped piece and is press-fitted to the insulation cutting part even if it is just 1, the insulation blocking body is only 1% of that.
Not only is the cost high due to the special cross-sectional shape, but also how to store it so that it does not twist in the current state, and how to press fit it into the frozen insulation cutting section so that it does not fall over. In addition, there are difficulties in how to press the sharp insulation strips without getting caught, and how fast to push them, and products manufactured by this method are not suitable for insulation use due to the shape and cost of the insulation base. Since the width of the cut portion cannot be made very wide, the heat bridge phenomenon is likely to occur due to the freezing of condensation.

Furthermore, this glaze F! The manufacturing method of JT thermal mold material is %
There is also a conventional method as described in Japanese Patent No. 140843/1983. That is, 21-metre metal profiles spaced apart from each other are connected together by a transition strip at the lower end to form an upwardly directed groove, and an insulating material is poured into the groove. After solidification, the bridging strip material was removed, and a separating strip material was blown between the 21 upper crosspiece profile materials separated and stacked at a distance from each other to form an upward clear sound. There are methods in which insulating material is poured into the port and solidified, but in the former of these, the cut surface due to the removal of the bridging strip is exposed on the outer surface, resulting in 1. Intrusibility and appearance are affected, and most of them are not only used for protection, cosmetic treatment, etc., but also for injection of insulating material if the height of the hollow space of the profile material is large. In addition, it can only be used for those where the insulating core material is located in the vertical range, and the insulating core material is, for example,
It cannot be applied if the degree direction has changed, or if the position is shifted in a step-like manner even if it is located above or below, and the applicable range is narrow. In addition, in the latter case, since the two upper profile members are separated, the number of parts increases, making it inconvenient to store and transport. This requires a temporary fixing frame material for placing the device in place, which has the disadvantage of making the device complicated and expensive.

The present invention has been developed in response to the above-mentioned prior art, and is made of a metal material and connects the outdoor side member 21 and the indoor side member 22 to the outdoor side j member 2I and the indoor @j member 22. A first groove 26 is connected by a connecting member 23.24 on the inner side of the outer surface, and forms an outward opening at the connecting member 23.24. and h 2 n'
The opening of the first groove part 26 of the first groove part 26 of the molded material B, Il-, ', ノ), which has a part of 27-metal metal, is turned completely upward and the first groove part 2 is turned completely upward.
A heat insulating material is injected and filled from above into 6 and hardened to form a first heat insulating body part, and the connecting member is cut from the bottom with a cutter or the like to form a heat insulating cut part, and this is made in the entire longitudinal direction. By inverting the shaft so that the opening of the second groove faces upward, and placing a heat insulating band-like member on the pair of inward locking pieces of the second groove, the entire bottom wall of the second groove can be closed. The disadvantages of the prior art described above are solved by forming the second heat insulating coupling body part by injecting and filling the heat insulating material from above and curing the heat insulating material.

The first feature of the present invention is that the outdoor side member is removed and the entire indoor side member is connected by a connecting member on the inner side of the outer surface thereof, and an outward opening is formed with the connecting member inward. With the opening of the first groove facing upward, a heat insulating material is injected and filled into the first groove from above and cured to completely form the first heat insulating connecting body.
By including the step of inverting the molded material around its longitudinal axis so that the opening of the second groove faces upward after cutting the molded material from l, it is possible to insert not only the first groove into which the insulation material is injected but also the second groove. Always place the VT near the insulation inlet.
Thermal material is injected and filled, and as a result, the hollow space of the heat insulating mold member has a large height, or an overhang between one heat insulating link body part and the other heat insulating link body part.
There are overhanging pieces, etc., and the cross-sectional shape of the shape material is irregular, such as those in which a plurality of heat-insulating connecting body parts are turned 90 degrees from each other, or those in which the shapes are staggered vertically. Also, it is possible to easily and reliably perform the injection and filling of the insulation system, and to make the cutting surface by cutting the connecting member at a position it1: isolated from the outer surface on the edge side of the insulation connecting body part, and to This is because it eliminates the need for troublesome post-treatments to protect the surface, such as corrosion prevention and cosmetic treatments on the cut surface.

Furthermore, the second feature of the present invention is that, by injecting and filling the first groove with a heat insulating material from above and curing it, the connecting member is removed from the entire bottom side, so that the connecting member can be removed in multiple places within the action range of the cutting tool. The purpose of this method is to make it possible to cut out the heat-insulating molded material in one go, thereby increasing the efficiency of manufacturing the heat-insulating molded material.

The present invention has fully developed the manufacturing method of such a heat insulating molded material, and the outdoor 0111 is made from a single gold PA molded material which is connected and integrally formed by an outdoor side member, an indoor side member, and all or a plurality of connecting members. The member and the indoor member are formed by filling and hardening molten heat insulating material and are connected by a plurality of heat insulating connecting body parts spaced apart from each other, and the surface can be easily and reliably assembled, and the machines and equipment used are simple. Moreover, it does not become large in size, and it has a wide range of applications, such as it can be applied to complex shapes such as those in which multiple connecting body parts are deviated by 90 degrees or steps in the hollow part, etc. Would you like to provide a complete manufacturing method for heat-insulating moldings that eliminates troublesome post-processing? It is a self-confessed thing.

As mentioned above, the method for manufacturing the heat insulating molded material according to the present invention can be applied to both the outdoor side member and the indoor side member. The first groove of the molded members connected by the connecting member on the inside of the outer surface faces upward, and the insulation material is applied from above to the first groove. After filling and hardening to form a first heat-insulating connecting body portion and cutting out the connecting member from the lower side, the molding material is turned around its longitudinal axis so that the opening of the second groove portion is fully directed upward. By having this, not only the first g part into which the heat insulating material is injected but also the second groove part can be always positioned close to the insulating material injection port before the insulating material is injected and filled.
The height of the hollow space of the heat insulating mold is large, or the cross-sectional shape of the mold is complicated because there is an overhang, an overhanging piece, etc. between one heat insulating connector and the other heat insulating connector,
For example, even if multiple insulating connectors are oriented 90 degrees from each other or are staggered vertically, filling and filling the insulation material can be done easily and reliably. In addition, the cut surface caused by cutting off the connecting member is isolated from the outer surface by the shell 1111 of the heat-insulating connector part ((()), and troublesome post-processing to protect the cut surface, such as removing the cut surface. There is no need to apply corrosion prevention or cosmetic treatments.

Furthermore, after injecting and filling the first groove from above with a heat insulating material and curing it, the connection member is removed. By cutting from the bottom, even if the connecting member is broken within the action range of the cutting tool, it can be removed all at once, making it possible to manufacture the heat insulating material with high efficiency.
