Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a building material such as a wall panel in which a panel frame and a face material are adhered by adhesiveness of urethane foam as a heat insulating material, and a heat insulating material which is also used as a formwork of a cloth base. The present invention relates to an apparatus, a jig, and a method for foam molding.

2. Description of the Related Art As a building member used for buildings having high heat insulation and high airtightness suitable for houses in cold regions, etc., the present applicant has proposed a wall panel and a heat insulation base using polyurethane as a heat insulating material as follows. . The wall panel integrates a panel frame and a face material by utilizing the adhesiveness of hard urethane foam used as a heat insulating material. Polyurethane is foamed by placing panel components such as a panel frame, a face material, and a base bar in a predetermined arrangement in a jig serving as a mold, and injecting polyurethane in this state. According to this, the step of attaching the face material, the base material, and the like with screws or nails becomes unnecessary, and productivity is greatly improved. Further, urethane foam has excellent heat insulating properties as compared with foamed styrene or the like used as a heat insulating material for ordinary houses. In the heat insulating foundation, the base formwork is made of urethane foam, and after the foundation concrete is cast, the base formwork made of urethane foam is left as it is as a heat insulating material of the foundation.
According to this, the demolding process is not required, and the on-site construction is simplified. In addition, it becomes the basis excellent in heat insulation.

[0003]

However, a facility for efficiently mass-producing a wall panel and a base form using such urethane foam has not been developed. As a foaming agent for hard urethane, fluorocarbon or a substitute material thereof is generally used, but any of these is not preferable from the viewpoint of the environment and flammability. Therefore, it is preferable to use water-foamed polyurethane for building members. As a general system for injecting such water-blown polyurethane, there are an open injection method and a closed injection method. The open injection method is a method of injecting while moving the nozzle, and it is possible to form a complicated shape, but in the case of a large-sized building member such as a wall panel or a foundation form, the moving distance of the nozzle becomes long. Therefore, it takes a long time for injection, and the apparatus becomes large, which is not preferable.

The closed injection method is a method in which an injection hole is provided in a sealed jig and an injection is performed by inserting a nozzle, and is suitable for a product having a simple shape. When the closed injection method is applied to the manufacture of wall panels, a multistage press method in which the stacked panels are fixed by a press and injected and a method in which a jig is continuously conveyed on a conveyor are considered. This multi-stage press system requires relatively simple equipment, but it is difficult to control the temperature of foam molding and the like, there is a problem in quality control, and it is necessary to load and unload panels, and it is difficult to improve productivity. In consideration of these, it was considered preferable to use a continuous conveying method by the closed injection method. However, in order to realize the foaming apparatus, the jig and the forming method of the continuous conveying method, a limited floor in the factory was used. In order to be able to mass-produce with good productivity in terms of area, it is necessary to develop a specific configuration.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and is capable of mass-producing building members using urethane foam with high productivity and easily controlling the quality of the building members.
The purpose is to provide jigs and methods.

[0006]

SUMMARY OF THE INVENTION A foam molding apparatus for building members according to the present invention comprises a plurality of jigs for forming foam by internally foaming polyurethane into building members, and these jigs are arranged in a column and conveyed. A preheating furnace and a heat retaining furnace each having a possible transfer device therein and arranged in parallel with each other; a preparation table provided in front of an entrance of the preheating furnace to prepare the jig in a predetermined state; and the preheating furnace. And an injection portion provided between the outlet of the heat insulation furnace and the inlet of the heat retaining furnace, for injecting water-foamed polyurethane into the jig. The building member referred to here is a component of the building, such as a wall panel or a heat insulating material also serving as a foundation form. The jig may be for injecting urethane into the entire internal space, or may be for inserting a building component such as a panel frame into the internal space and injecting urethane into the interior.

According to this foam molding apparatus, a jig is prepared in a closed state or the like on a preparation table and is sent to a preheating furnace. If it is necessary to put the building component material in the jig, it can be performed on this preparation table. The jig sent to the preheating furnace and the building member components inside the jig are heated to a predetermined temperature while being sent through the preheating furnace by the transfer device, and urethane is injected by the injection unit at the place where the preheating furnace exits. . Due to this injection, the polyurethane foams in the jig or in the constituent material of the building member therein, and hardens while the jig passes through the heat retaining furnace. In this way, the foaming of the building member is performed while continuously transporting the plurality of jigs. Therefore, a large number of building members can be mass-produced efficiently. In this case, since the jig is transported in the preheating furnace and the preheating furnace to perform preheating and heat preservation, it is easy to control the temperature of the jig and the building member components before urethane injection and to manage the heat preservation after the pouring. And foam molding of high quality building members. For example, in a case where the building member constituent material is put into a jig and foam-formed, the building member constituent material and the urethane foam can be securely bonded.

[0008] In the foam molding apparatus having this configuration, any one of the plurality of jigs may be a jig for a wall panel. This jig for a wall panel has a jig body with an open top for accommodating the panel frame and the surface materials on both sides in a laid state, and a jig lid for covering the top opening of the jig main body. With the jig for a wall panel having this configuration, the panel frame and the surface materials on both sides are placed in a predetermined arrangement in the jig, and the urethane is injected, so that the adhesiveness of the urethane foam is applied to the panel frame and the surface. It is possible to produce wall panels in which the materials are fixed to one another.

Further, any one of the plurality of jigs may be a jig for forming a base heat insulating material which also serves as a base formwork.
This foundation jig has a jig main body and a jig lid that can be divided from each other. By using this jig for foundation, a basic heat insulating material as a building member can be manufactured continuously by this foam molding apparatus. These wall panel jigs and foundation jigs may be used in combination. In this case, a preparation table for a wall panel jig and a preparation table for a foundation jig are juxtaposed as the preparation table. In addition, a transfer table for feeding a jig between the ends of the two transfer apparatuses is provided. Thereby, both the wall panel and the basic heat insulating material can be continuously foam-molded using the same foam molding apparatus.

[0010] In the foam molding apparatus having this configuration, it is preferable that a jig lid attaching / detaching apparatus that lifts the jig lids of the wall panel jig and the foundation jig is provided above the transfer conveyor. By providing the jig lid attaching / detaching apparatus in this manner, when preparing for demolding and loading of a panel frame for manufacturing the next wall panel, etc. on the preparation table, the jig body is opened and the preparation table is opened. And the jig lid can be stored for good workability. Also, the work of attaching and detaching the jig lid to and from the jig main body can be efficiently performed. It is desirable that the jig bodies of the wall panel jig and the foundation jig have a planar shape having substantially the same size as each other. In this case, the basic heat insulating material is generally smaller than the wall panel, but in this case, the jig body of the basic heat insulating material is provided with a transfer base portion to be equal in size to the wall panel jig. In this way, by equalizing the size of the wall panel jig and the foundation jig, accurate conveyance can be performed to both jigs by using the same conveyance device in each furnace or outside the furnace. For example, even when a guide member or the like is provided so as not to be displaced with respect to the injection portion or the like, the common guide member can guide the jig for the wall panel and the jig for the foundation.

A wall panel jig according to the present invention is a foam molding wall panel jig which can be conveyed on a conveying apparatus, and has an upper surface opening for laying down and accommodating a panel frame of a wall panel and surface materials on both sides. And a jig lid for covering the upper surface opening of the jig main body. The jig main body has side frames on four sides on a bottom plate, two adjacent side frames serve as reference members for arranging a panel frame, and the remaining two side frames can be opened outward. The jig lid is provided with a fluid pressure type clamp device coupled to the jig body, and a fluid path for supplying the working fluid of the clamp device is provided with a coupling for closing the flow path in a detached state. In this way, by setting the jig body to be open on two sides and the two sides serving as a positioning reference, the work of disposing the panel frame or the like in the jig can be easily and accurately performed. In addition, the demolding operation after foam molding can be easily performed. Further, by providing the coupling, the clamp device can be operated by a fluid supply device or the like provided at a fixed position in the jig circulation path, and the clamped state can be maintained during conveyance.

[0012] The foam molding method of a building member according to the present invention is a foam molding method using a foam molding apparatus in which a preparation table for the wall panel jig and a preparation table for the foundation jig are juxtaposed. The wall panel jig and the foundation jig are carried into the preheating furnace substantially alternately. According to this method, the jig for the foundation
While attaching the jig lid to the jig body and preparing to carry it into the preheating furnace, for the wall panel jig, it is possible to put the panel frame etc. into the jig body on the preparation table. . In addition, while preparing to carry the jig for the wall panel into the preheating furnace, preparation work such as demolding can be performed on the preparation table of the jig for the foundation. Therefore, it is possible to carry in and out the furnace while minimizing the dead time. When a general two-story house is considered, the number of wall panels and basic heat insulating materials required for one building substantially matches the number that can be produced by alternately molding in this way.
