Description

[Detailed description of the invention] This invention is a heat insulating frame that constitutes window frames, shoji frames, and other architectural components, and is a heat insulating frame material in which indoor and outdoor members are joined by narrowing the heat insulating material. Regarding equipment.

As shown in FIG. 1, the heat insulating frame material consists of an indoor member 2 and an outdoor member 3 made of extruded aluminum alloy members that are connected in parallel with each other with a space through a connecting member 1 that is removed later. It is obtained by injecting and hardening a heat insulating material 4 such as urethane resin into the space between the materials 2 and 3, and then removing the connecting member.

Conventionally, the method generally adopted for injecting the heat insulating material 4 is a very basic method in which the mold is propped up, the lower end of the space is sealed, and the heat insulating material, which hardens after filling, is filled from the upper end. It was hot.
With this method, if you try to inject under pressure, air will be drawn in, forming large bubbles or unfilled areas inside, resulting in a large number of defective products, so you have no choice but to rely on gravity filling due to its own weight. However, since careful attention must be paid to prevent air bubbles from entering, there is a serious drawback that the filling time becomes long. Furthermore, since the air in the space must be released from the same port as the filling port, the size of the filling cross-sectional area is naturally limited and cannot be applied to thin shapes, resulting in extremely low efficiency.

This invention was made in order to solve the above-mentioned conventional drawbacks, and the purpose is to provide a heat insulating frame material manufacturing device that can reliably fill the heat insulating material regardless of the thickness of the mold material and can significantly shorten the filling time. The feature is that a heat insulating frame material is manufactured by filling a molded material with a heat insulating material filling space inside the pre-prepared interior material, outdoor material, and a connecting member that connects these two components with a heat insulating material. and an inclined pedestal on which the mold is placed, and an inlet for filling the heat insulating material, which is fixed to the lower part of the trestle and supports the lower end of the mold, and communicates with the heat insulating material filling space. a fixing plate; a lid plate that can be operated to freely open and close the injection port of the fixing plate; and a cover plate that is slidably provided on the top of the pedestal to close and support the upper end of the mold material, and the air is communicated with the heat insulating material filling space. The apparatus also includes a movable plate having an overflow port for discharging the heat insulating material, and an adjustment mechanism that can adjust the sliding movement of the movable plate.

In this invention, the "connecting member" refers to a peelable wall that is connected to the upper and lower walls of the interior and exterior materials with a thin wall as a boundary and can be peeled off from the thin wall, or a peelable wall that is continuously formed with a normal wall thickness and that is subsequently planed. The indoor member and the outdoor member may be separated by cutting with a board or the like, or the connecting member may be formed from an extruded material separate from the indoor member and the outdoor member, and the upper and lower walls of these two members may be attached with adhesive, etc. Also includes those bridged by

In addition, "thermal insulation material" is a foamable or non-foamable synthetic resin or synthetic rubber such as urethane resin or vinyl chloride resin, which is a liquid, bead-like, or powdery fluid when filled, and which undergoes a chemical reaction after filling. It also refers to a material that hardens upon cooling to room temperature, has low thermal conductivity, and engages or adheres to and joins indoor and outdoor materials.

Embodiments of this invention will be described in detail below with reference to FIGS. 2 to 10.

2A and 2B are a plan view and a front view schematically showing the device according to this invention, in which 5 is a mold material, 6 is a pedestal, 7 is a fixed plate, 8 is a cover plate, 9 is a movable plate, and 10 is an adjustment plate. Mechanism 11 is a nozzle of a heat insulating material filling device. The pedestal 6 is arranged so that it can be tilted freely from 0 to 5 degrees to 20 degrees, and as shown in FIGS. 3 and 4, two long square members 12, 12 are arranged in parallel, and It is constructed by nailing together a plurality of intersecting cross members 13, which are spliced to a desired length using appropriate reinforcing materials 14. Horizontal member 13... On top, four inverted trapezoidal rails 15 made of, for example, Bakelite with good sliding are installed at equal intervals in parallel with the square member 12 and at a predetermined length, and four rails 15 are installed at a predetermined length at the same time. It is now possible to fill with insulation material. As shown in FIG. 5, the fixing plate 7 is a metal L made of a vertical closing part 16 and a horizontal mounting part 17 with respect to the frame, which is larger than the cross-sectional area of the heat insulating material filling space of the mold material 5.
The shape member is bolted 18 to the rail 15 or cross member 13 on the lower side of the pedestal 6, and closes and supports the lower end of the shape member 5 at the closing portion 7. An inlet 19 for filling the heat insulating material, which communicates with the heat insulating material filling space, is formed approximately in the center of the closing portion 16 by removably fitting a nipple 20 made of stainless steel. This nipple 20 is provided to facilitate fitting of the nozzle 11 of a filling device (not shown), to eliminate leakage of the heat insulating material, and to facilitate injection. The cover plate 8 has one end pivotally attached to the front surface of the closing portion 16 of the fixed plate 7 with a bolt 21, and a lever 22 provided at the other end.
2, the injection port 19 is rotated about the pivot point, and the injection port 19 can be opened and closed in an overlapping manner. This cover plate 8 only needs to open the injection port 19 when injecting the heat insulating material 4 and close it after filling.
The structure is not limited to the above structure, and for example, a plug may be fitted in a detachable manner. A silicone rubber sheet 23 is interposed between the injection port 19 and the lid plate 8 in order to improve airtightness and releasability of the heat insulating material and the lid plate 8, and a fixing plate 7 is placed in contact with the lower end of the mold material 5. Similarly, a silicone rubber sheet 24 is interposed between the back surface of the closing portion 16 and the silicone rubber sheet 24 to improve mold release and prevent liquid leakage.

Although the fixed plate 7 was fixed with bolts 18,
It may be possible to slide this along the rail 15, and in this case, once the position is determined, it is necessary to fix it by appropriate means. The movable plate 9 is an upright closing plate 25 larger than the cross-sectional area of the insulation material filling space of the mold material 5.
and an engagement plate 26 connected to the adjustment mechanism 10 described later.
It is an aluminum metal frame-like body connected in parallel with long bolts 27, and the lower sides of both plates are connected to the rail 1.
An inverted trapezoidal recessed part (not shown) is formed to fit with the mounting plate 5, and the plate is slidably attached to the upper part of the frame with the closing plate 25 side facing the fixed plate side. At approximately the center of the closing plate 25, an overflow port 28 for discharging heat insulating material and air that communicates with the heat insulating material filling space is formed by removably fitting a nipple 29 made of stainless steel.
A nipple 29 protruding from the back surface of the closing plate 25 is connected to a transparent pipe 30 leading to a receiving tank (not shown) for storing excess heat insulating material. This prevents the upper end of the mold from being contaminated by the heat insulating material. The reason why the pipe is made transparent is so that the filling level can be visually judged, and the reason why the movable plate 9 is made into a frame-like body is to make it easy to attach and detach the disposable transparent pipe 30. A silicone rubber sheet 31 is interposed on the front surface of the closing plate 25 to improve mold release from the heat insulating material 4 and to prevent liquid leakage. The adjustment mechanism 10 includes a base 32 that can slide on the rail 15 and is bolted in an appropriate position.
and a support cylinder 33 that is attached to the base 32 and has a thread groove carved inside, and is screwed into the thread groove of the support cylinder 33,
A screw rod 3 having one end loosely fitted into the engagement plate 26 of the movable plate 9 so as not to come off, and a handle 34 provided at the other end.
5, and by rotating the handle 34, the movable plate 9 can be adjusted and fixed so as to be movable forward and backward.

Next, the operation of the above structure will be described. The long shape material 5 prepared in advance has its lower end in contact with the back of the fixed plate 7, and its upper end in contact with the closing plate 25 of the movable plate 9, which is moved forward and backward by the operation of the handle 34. It is held down and clamped and supported at the desired inclination. In this case, if the pedestal is tiltable, it is tilted only when filling with the heat-insulating filler. Next, the nozzle 11 of the filling device (not shown) is inserted into the injection port 19 exposed by opening the cover plate 8.
A known compounded liquid 36 which becomes polyurethane through a pressure reaction is press-fitted from the lower end of the mold material 5. For this reason, it is even better to use a filling device that has a variable discharge rate so that filling can be completed within a certain period of time (of course, taking the curing time into consideration) regardless of the length of the mold material 5 and the filling volume. Effective. Inlet 19
As shown in FIG. 7, the injected liquid mixture 36 begins to fill the heat insulating material filling space A upwardly from below, and the corresponding amount of air escapes from the overflow port 28. Here, if the length of the mold material 5 is long, if the slope is large, the discharge pressure of the filling device must be increased, resulting in a heavy load, so it is preferable that the slope is not too large. When the heat insulating material filling space A is completely filled to the upper side, excess liquid mixture 36 escapes from the overflow port 28 in place of air, and this can be confirmed through the transparent pipe 30. After checking, stop the injection, remove the nozzle 11, and remove the lid plate 8.
to seal the injection port 19. After the curing time has elapsed, the handle 34 is rotated to move the movable plate 9 backward, releasing it from the fixed plate 7, and removing the profile 5. In this way, four heat insulating material-filled mold members are obtained. In the final step, the connecting members 1, 1 connecting the indoor and external members 2, 3 are removed by peeling or cutting, and the heat insulating frame material is completed. In addition, transparent pipe 3
0 is disposable, and nipples 20 and 29 are reused after removing the hardened heat insulating material. Figure 8 shows another example in which an unfilled space B exists in the middle of the heat insulating frame material, but this would consume a large amount of heat insulating material if the entire space filled with heat insulating material was filled, and especially expensive urethane resin etc. This was developed to solve the problem of the extremely high cost when used, and the long time it takes to fill and harden a heat insulating material such as urethane resin, which reduces work efficiency. In order to manufacture such a heat insulating frame material, a core 38 of a dough material is placed in the space B of the pre-prepared mold material 37 over the entire length of the mold material 37 using a hollow aluminum alloy extruded mold material with a rectangular cross section as shown in FIG. Insert as shown, thereby inserting core 38
Closed filling spaces C and C remain above and below. As in the previous embodiment, the upper and lower ends of the profile 38 are closed and supported by a fixed plate and a movable plate, but the fixed plate 39 and the movable plate 41 have filling spaces C and C, respectively.
The difference is that two inlets 41 and two overflow ports 42 are provided corresponding to the two. Note that the core 38 is pulled out after being filled and hardened with the heat insulating material, but since it is made of dough and can be easily released from the mold, it can be removed extremely easily by pressing from one side.

When there are two or more injection ports like this, two or more nozzles must be prepared, which makes the filling device bulky and cannot be used efficiently. In order to solve this problem, it is conceivable to branch one nozzle into two or more. However, if the pipes are branched, the respective discharge pressures and discharge amounts will be different, which will actually cause problems, which is not preferable. The method shown in FIG. 10 solves this problem. That is, in the case shown in Figure A, there is only one injection port 43, and instead, the core 44 is made somewhat shorter than the mold material, the lower end of the core is closed, and it is floated away from the fixing plate 45 to form a small chamber 46. . The heat insulating material injected in this way is placed in this small chamber 4.
6, the flow will be divided into the upper and lower filling spaces, so
The discharge pressure and discharge amount in each filled space can be made uniform. The lower end of the core 44 is closed as shown in FIG. It is the same even if formed.

On the other hand, the overflow opening 50 of the movable plate 49 at the upper end of the shape is 2
If there are more than two chambers, the workability will be poor, but this can be reduced to one chamber by applying the structure of the small chamber at the lower end as shown in FIG. However, in this case, the number of working means for removing the core increases, but if a molded heat-retaining material, such as wood, is used instead of the reused core, it can be left inside the mold material, making it unnecessary to remove the core, making it more convenient. good.

As mentioned above, this idea tilts the mold material,
Since the heat insulating material is injected from the lower end, it is possible to perform reliable filling without entrainment of air, and the filling speed can be significantly increased compared to the conventional method. Therefore, the cross-sectional area of the filling space is not affected by the size difference or the length of the profile, and there is a remarkable effect that the working time can be significantly shortened.

Furthermore, this invention is equipped with a transparent pipe that is connected to the overflow port of the movable plate and guides the overflowing insulation material to the storage tank, so that the full state of insulation material in the insulation filling space can be prevented from flowing out into the transparent pipe. Since the amount of insulation material filled can be checked accurately and reliably, problems caused by overfilling or underfilling the insulation material can be resolved, and overflowing insulation material is guided to the storage tank. There is no contamination of the surrounding area, and overall productivity is improved.
