Detailed Description of the Invention

[0001]

The present invention relates to a suitable building board with the outer wall of a building, in particular, it relates to a production equipment of the building board having improved water resistance function of the back surface.

[0002]

2. Description of the Related Art Conventionally, at the beginning of a building board coating process, back sealer coating is applied to the back surface of the board of the building board in order to impart some waterproofness. The coating amount in that case is about 45 to 55 g / m ² in the wet state, and the thickness of the sealer coating film after drying is about 10 to ²⁰ μm. Since the sealer is adhered to the back surface of the plate, the film thickness is reduced by the amount of the sealer impregnated inside the porous plate. The term "sealer" as used herein refers to a paint that is used to fill the pores of the porous, highly absorbable surface to be painted, and normally a colorless and transparent acrylic urethane-based paint is often used. .

[0003]

By the way, although the back surface of the cement substrate (which is a plate in a state before coating) manufactured in the substrate manufacturing line is formed to be substantially flat, the whole substrate is It is difficult to say that the density of the plate in the thickness direction is not always uniform, because there are fine irregularities and a large number of voids. Therefore, in terms of the sealer permeability in the back sealer application process in the continuous coating process of the building board,
Inevitably, the problem of partial coating unevenness is unavoidable, and in such a case, the desired waterproof effect cannot be sufficiently exerted.

On the other hand, increasing the coating amount of the sealer on the back surface of the building board, which is not directly visible in normal use, causes a large increase in product cost. Absent. Originally, unlike the coating layer on the surface, the function that the sealer layer should exhibit is that it is not the part that is directly exposed to rainwater, so it is sufficient if the sealer layer can exhibit a certain degree of waterproofness as the back surface of the substrate. The current situation is that painting is done. Therefore, little attention is paid to other physical properties such as scratch strength, and the film is not strong in terms of strength.

Due to this, there is a sufficient risk that scratches will occur during distribution or at the construction site, and if scratches occur once,
Penetration of water from that part is inevitable. In some cases, some kind of shock may cause a fatal defect such as a loss of the real part. In view of such a current situation, the present applicant has previously applied for “building board and its manufacturing apparatus” in which a plastic substrate is lined with a cement substrate material (Japanese Patent Application No. 11-185410).

However, the following problems still remain in the invention of this application. That is, as shown in FIG. 2A, in the construction method in which the nail 5 (or screw) is driven in from the surface of the building board 201 to be fastened, the nail 5 is in a state of protruding from the back surface of the building board 201. The vicinity of the portion 206 is in a cracked state, and the cement substrate 202 is broken. Therefore, rainwater that has entered the back surface of the building board 201 from the nailed portion of the nail 5 (that is, a slight gap between the nail or the screw and the board) is applied when the conventional sealer layer 204 is applied or when the plastic sheet lining is previously proposed. However, it cannot be avoided that the cement substrate 202 goes around to the back surface.

In view of the above problems, the present invention eliminates the back sealer application and the subsequent drying step, and effectively exerts the waterproof function of the sealer layer conventionally formed on the back surface of a building board. a is, and to provide a manufacturing <br/> ZoSo location of the building board can be satisfactorily protect the back surface of even the nailing Incidentally building board.

BEST MODE FOR CARRYING OUT THE INVENTION Preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Figure 1
FIG. 3 is a diagram showing a partial cross-sectional structure of a building board according to an embodiment of the present invention. The building board 1 has a structure in which a surface coating layer 3 is provided on the front surface of a cement substrate 2 and a back surface is lined with a foamed plastic, preferably a polyethylene (PE) foamed layer 4. The cement substrate 2 is formed by pressing and curing a raw material mat formed by forming or extruding a raw material slurry on a porous support.
The raw material slurry is, for example, Portland cement, or blast furnace cement in which blast furnace slag is mixed in Portland cement, fly ash cement in which fly ash is mixed, volcanic ash, silica fume, silica cement in which silica materials such as clay are mixed, alumina cement, blast furnace slag. Cement-based inorganic hydraulic materials such as wood powder, wood wool, wood chips,
Wood fiber, wood pulp, softwood pulp, hardwood pulp,
Wood fiber bundle, waste paper pulp, hemp fiber, bacus, chaff,
Wood reinforcing materials such as rice straw and bamboo fiber, and if desired, aggregates such as perlite, silas balloons, expanded shale, expanded clay, calcined diatomaceous earth, fly ash, coal husks, foam concrete crushed materials and alkali silicates. A curing accelerator such as a metal salt,
A wax, wax, paraffin, surfactant, silicone or other waterproofing agent or water repellent is dispersed in water to obtain a solid content of usually 5 to 2.
It is adjusted to about 0% by weight.

For the PE foam layer 4, a resin foamed by a normal pressure foaming method is preferably used. Linear polyethylene is preferable because it has excellent chemical resistance. Non-crosslinked ones are preferable because they can be regenerated. By adjusting the material density, a wide range of PE foam layers 4 from soft types to semi-hard types can be manufactured. In addition, by adjusting the kneading amount of the foaming agent,
The E foam layer 4 can be molded. The thickness of the PE foam layer 4 is
0.5-3.0 mm is suitable. When the thickness is less than 0.5 mm, a problem occurs in strength, and the waterproof property cannot be sufficiently exerted. Conversely, 3.
If the thickness exceeds 0 mm, the building board as a whole will be unnecessarily bulky and the commercial value will decrease.

The normal pressure foaming method is, for example, an extruder in which a foaming olefin resin composition such as polyethylene or polypropylene is mixed with a pyrolytic foaming agent such as azodicarbonamide in advance at a temperature at which the foaming agent does not decompose. Melt kneading with a roll or a roll, and the kneaded product is preformed into an appropriate shape such as a sheet by extrusion molding, press molding, or other appropriate means, and the preformed product is introduced into a heating chamber to decompose the foaming agent. It is a method of foaming the resin under normal pressure by heating above.

Besides, known foaming methods such as an extrusion foaming method and a pressure foaming method can be applied. The extrusion foaming method is, for example, melt-kneading a resin composition for foaming with an extruder, and an expanding liquid type foaming agent such as dichlorotetrafluoroethane from a foaming agent inlet provided in the kneading section of the extruder. Alternatively, an inert gas type foaming agent such as carbon dioxide gas is pressed into the molten resin, or a mixture of the above foaming resin composition and a pyrolytic foaming agent such as azodicarbonamide is melted in an extruder. It is a method of kneading and extruding this from an extrusion die while foaming it into an appropriate shape.

In the pressure-foaming method, for example, a foaming resin composition is melt-kneaded by an extruder or a roll, and the kneaded material is preliminarily formed into a sheet or other appropriate shape by extrusion molding, press molding or other appropriate means. After molding, the preform is placed in a pressure chamber such as an autoclave and heated under pressure, and an expansive liquid foaming agent such as dichlorotetrafluoroethane or an inert gas foaming agent such as carbon dioxide is added to the preform. This is a method in which the surface is impregnated and then the pressure in the pressure chamber is released to cause foaming. Further, the foaming agent used in each foaming method is not particularly limited, low-boiling organic solvent,
Intumescent liquid type foaming agent such as swelling agent, inert gas type foaming agent,
Any foaming agent such as a pyrolytic foaming agent can be used.

FIG. 2 is a diagram for explaining a cracking condition on the back surface of the building board in the case of nailing. As described above, in the case of applying the conventional sealer layer 204 shown in FIG. 2 (a) or the previously proposed plastic sheet lining, rainwater that has entered the back surface of the building board 201 must flow to the back surface of the cement substrate 202. Can't be avoided. However, as shown in FIG. 2B, in the case of the present invention, cracks and chips on the back surface of the building board 1 are prevented.

FIG. 3 is a flow chart for explaining the PE foam layer backing process of the building board manufacturing apparatus of this embodiment.
The process within the broken line is the process according to the present invention and is inserted into the conventional process. A drying process after clear coating of an ordinary building board manufacturing apparatus (step S10)
1) receiving the supply of the plate a to be processed (step S10)
2) The base fabric 11 (described later) coated with the unfoamed foamed plastic is supplied (step S10).
3) By heating the base cloth 11, the foamed plastic is heated, melted and foamed (step S104), and the base cloth 11 and the plate a are laminated (step S1).
05), rapid cooling (step S106), and the processed plate a
Is carried out (step S107), and then the cooling (step S10), which is a normal process of the building board manufacturing apparatus, is performed again.
8) Then, the excess foamed plastic protruding from the contour boundary of the plate a is cut or trimmed (step S109), the inspection plate (step S110) and shipping (step S111) are performed.

FIG. 4 is a top view showing the construction of the building board manufacturing apparatus of this embodiment, and FIG. 5 is a side view thereof. The work plate a is designed to be carried on a predetermined carrying path by a carriage cart CC (described in detail from FIG. 8 onward).
In FIG. 4, the position where the plate a to be processed moves is indicated by a chain double-dashed line. The special laminated sheet wound in a roll shape (hereinafter referred to as the base fabric 11, specifically, shown in FIG. 6) is
After being fed from the base cloth roll 12, the front rotary roller 1
The pin tenter 16 driven by the roller 3 and the rear rotary roller 14 is run by being pinned by the pin pressing roll 15 and wound on the residual cloth roll 17. First, the base cloth 1
When 1 passes through the far-infrared heating zone ZA, the far-infrared heater 18 receives a non-contact heat treatment from above. Here, for example, by heating the base cloth 11 at 175 ° C. for 10 seconds, the P on the base cloth 11 is reduced.
The E coating portion 32 is heated from room temperature (30 ° C.) to 165 ° C. As the temperature rises, the PE coating portion 32 on the base fabric 11 undergoes a state change of softening → melting. Then, in the molten state, it moves to the subsequent laminating zone ZB.

A plate supply zone ZC is provided on the side of the laminating zone ZB, and the plate a that has exited the dryer after clear coating is a carriage cart CC to be described later.
It is brought in with it set to. From the plate position (1) to the plate position (2), the laminating process of placing the plate a to be processed on the base fabric 11 is performed. In the laminating process, in general, it is easier to support the to-be-processed plate a, the laminating process itself is easier, and the device configuration is often simpler when the back side of the to-be-processed plate a is processed upward. However, for example, when using a transport roller, there is a risk that the plate surface will be damaged (desperate in the case of a work plate a with severe irregularities), and from the dryer, Since it usually comes out with the plate surface facing up, here, the laminating process is performed with the plate surface facing up.

In this laminating process, the laminating process is performed by placing the back surface of the plate a to be processed on the PE coating portion 32 which is already in a foamed state. At the same time, the back surface of the base fabric 11 hung on the pin tenter 16 is The heating is performed by the heat roll 19, and the PE coating portion 32 is controlled so that the temperature rises from 165 ° C. to 185 ° C., for example. The temperature rising curve at this time is determined by actually performing a test, but at first, the temperature is gradually raised to gradually start foaming. Then, at the position immediately before reaching the bonding position, the temperature is raised so that the degree of foaming is about 60%,
The degree of foaming is controlled with the lapse of time, such as reaching 80% at the bonding position and reaching 100% immediately after that, and the temperature rise curve is determined in consideration of the traveling speed of the pin tenter 16. After the lamination, the thickness of the PE coating portion 32 in the foamed state is adjusted to a desired value by the clearance adjusting roll 20, and cold air is applied from the cold air supply duct 21 toward the back surface of the base cloth 11 hung on the pin tenter 16 so as to be provided on both sides. The first-stage cooling process is performed by exhausting the exhaust from the exhaust duct 22. For example, the PE coating portion 32 is 185 ° C. →
Control is performed so that the temperature drops to 140 ° C.

Subsequently, the work plate a exiting the laminating zone ZB (at that time, the work plate a is placed on the PE coating portion 32 on the long continuous base cloth 11).
Is transported to the subsequent cooling zone ZD in that state, where the front and back surfaces of the plate a to be processed are cooled, and, for example, 140
Control is performed so that the temperature drops from ℃ to 70 ℃. Then, at the plate position (3), the pin tenter 1
The base cloth 11 is separated from the base material 6, and the plate a having the PE foam layer 4 formed on the back surface is separated from the base cloth 11.

In this case, the base cloth 11 is pushed up by the pin removing roll 24 whose position is adjusted by the adjuster 23, so that the base cloth 11 is prevented from winding around the pin tenter 16. At the same time, the processing blade a having the PE foam layer 4 attached to the back is separated from the base cloth 11 by the separate blade 25 (see FIG. 7). Further, the remaining base cloth 11 from which the PE foam layer 4 has been separated is wound around the residual cloth roll 17.

The laminated plate a, which has been conveyed to the plate position (4), is removed from the carriage cart CC there, placed on the lower conveying roller 26, and cooled in the cooling zone Z.
It is carried out from D. Here, the upper surface position of the transport roller 26 is set to be lower than the base fabric surface position transported by the pin tenter 16. In the cooling zone ZD, the upper cold air supply duct 27 and the lower cold air supply duct 28 positively blow the cooling air to the front and back surfaces of the plate a to be processed, and the air after the blowing is provided on both sides. The exhaust duct 29 is used to collect the exhaust gas. Carriage cart CC is in the cart return zone ZE
To the start position in the plate supply zone ZC.

FIG. 6 is a view for explaining the base cloth 11. This base cloth 11 is, for example, a rectangular shape with an area of a little protruding from the back surface of the plate a to be processed, on the surface of a long heat-resistant recycled PET (polyethylene terephthalate) nonwoven fabric (or woven cloth) 31. Unfoamed PE coating part 32
Of the PE foam layer 4 of the building board 1 when the surface of the base cloth 11 is thinly coated with a heat-resistant release agent that does not hinder the coating.
The detaching operation of the recycled PET non-woven fabric 31 from can be performed more smoothly. The distance between the PE coating portions 32 on the base fabric 11 is determined according to the processing speed. For example, when the plate position (2) in FIG. The position of the coating portion 32 is set such that it is at the plate position (0) in front of the far infrared heating zone ZA.

FIG. 7 is a view showing a state in which the plate a to be processed and the remaining base cloth 11 are separated from the pin tenter 16. Base cloth 11
A separate blade 25 having an appropriately rounded R is abutted against the boundary between the base fabric 11 and the PE foam layer 4 at an adjustable angle so as not to break, and the two are separated.

FIG. 14 shows the PE coating portion 32 (◆
And a carriage cart CC (represented by ⋄) that conveys the plate a to be laminated on the back surface thereof. The horizontal axis shows the running road of "◆", and "◇" joins from the joining point y. (0) indicates the plate position (0) shown in FIG. 4, and at the detection point x, it is detected by a color mark sensor or the like that the front end of “♦” has passed. In order to laminate the PE-coated portion 32 and the plate a to be processed, it is necessary that both of them travel at substantially the same position and at the same speed during lamination. However, while "◆" is traveling at a constant speed on the base fabric 11, "◇" starts direct traveling for laminating from the confluence point y, so "◇" comes with "◆". It is necessary to start running at the previous timing.

FIG. 15 is a diagram for explaining the speeds of "◆" and "◇". Time is plotted on the horizontal axis, and both speeds are plotted on the vertical axis. "◆" runs at a constant speed v1 (the running speed of the pin tenter 16), while "◇" increases the speed smoothly from the initial speed 0 to speed v1,
After that, it is shown that the vehicle runs at a constant speed. Since the travel distance until the two speeds match is the time integration of the speeds, in the case shown in the figure, "◆" travels almost twice as long. Therefore, this distance difference v1 × t1 (sec)
"◆" is detected at the position x corresponding to
If "◇" is started from the starting position (1) and accelerated at the timing when "◆" is detected, when the speed of "◇" matches the speed of "◆", both will be in the same position. You will be traveling at speed. After that, when “◆ 2” passes the detection position x t2 seconds after the detection of “◆ 1”, the cart 2 “◇ 2” is similarly departed from the departure position (1) at the detection time. I shall. As a result, the preceding cart and the succeeding cart are controlled so that an inter-vehicle distance equivalent to elapse of t2 seconds is ensured at the time each of which passes the departure position (1).

As described above, as long as the pin tenter is operated at a constant speed and "◆" is coated on the base cloth at a predetermined interval, the above-described transport / travel control can be performed for the cart. Thus, the laminating process can be smoothly performed. The starting position (1), the length of each part of the transport path, and the like are set to an optimum length within an allowable adjustment range in the timing operation with the pin tenter 16 in the transport operation of the cart.

16 and 17 are views for explaining the operation of the hanging hand 48 during the laminating process. While the carriage cart CC travels from the plate position (1) to the plate position (2) shown in FIG. 4, the front and rear ends P and Q of the front and rear ends of the plate a to be processed are shown in FIG. The rack gear 54 is used to control the lengths of the rack gears 54 so that each of them can be drawn. By controlling in this manner, the upper surface of the base fabric 11 running below the plate a to be processed is approached while gradually decreasing the inclination angle. Then, at the plate position (2), the back surface of the plate a to be processed is completely landed on the PE coating portion 32. So-called work plate a
The soft landing on the PE-coated portion 32 will be realized, and reliable lamination can be performed without entraining air as much as possible.

The operation of the lifting hand 48 (lowering operation and lifting return operation) is performed by operating the rack gear 54 attached to the upper portion of the pipe of the lifting hand 48, and the driving is performed by the stepping shown in FIGS. 9 and 10. The motor 55 is used, and its rotation speed and rotation direction are controlled according to a pulse conversion program created based on the locus curve shown in FIG.

Each carriage cart CC to be used is given an ID number and is registered in the main controller 100 in advance. The main controller 100 wirelessly manages the operation status of each carriage cart CC. Specifically, according to the detection information of the PE coating portion 32 by the color mark sensor 105, the carriage cart CC at the starting position (1) is instructed to start. If each carriage cart CC wirelessly informs the main controller 100 that it has arrived at the four corners of the cart transport path, for example, all the carriage carts CC will be displayed in the main controller 100 as time passes. Since it is possible to roughly know which position on the cart transport path, this can be converted into display information and displayed and displayed on the display 108, and an abnormal situation can be found.

See), and stop the system.

A problem that a plurality of carriage carts CC arrive at two or more (four if there are many) corners at the same time and wireless communication from each cart controller 110 to the main controller 100 is solved is solved. Therefore, in the present embodiment, the main controller 100 calls each cart controller 110 at a predetermined polling speed to make an inquiry about each arrival time at each corner section. In response to the inquiry, in each cart controller 110, if there is uncontacted arrival information, “own ID number”, “arrival time at the last passed corner”, and “its corner number” To the main controller 100 as a response message.

Further, in the main controller 100, when there is a contact message about arrival at the corner section directly from one of the cart controllers 110, during the inquiry by polling,
The contact message shall be accepted as interrupt input data. In this case, each cart controller 11
As a contact message from 0, "own ID number"
"The arrival time of the corner that arrived" and "the corner number".

When the message from the carriage cart CC includes the measurement data of the elapsed time from the arrival time of each corner portion, it becomes possible to grasp the approximate current position of each cart on the transportation / traveling path. The response message and the contact message are distinguished by, for example, flagging the former message data. If it is a response message, the check in step S59 is "whether or not the corner section contacted as the previously passed corner section has arrived according to the movement schedule table" and the contact message. If it is, it is checked "whether the contacted corner section has arrived according to the movement schedule table". Specifically, regarding the arrival time you contacted,
For the scheduled arrival time shown in the movement schedule table,
If the range allowed for system operation is OK, the scheduled arrival time close to the contacted arrival time in the column of the corresponding corner number that was contacted in the movement schedule table is searched, and the planned arrival ID number is notified. It is to be checked whether or not it matches the received ID number.

If they do not match, it means that the carriage cart CC that has contacted or responded to the inquiry is not transported / run according to the movement schedule table. System stop processing "is executed. In the system stop process, each cart controller 110 is instructed to execute the system stop process by wireless communication by broadcast communication. Also,
Emergency stop is applied to other drive systems. After that, the system stop processing on the software is executed.

FIG. 24 shows step S51 of this embodiment.
It is a figure which shows the example of the movement schedule table created by (refer FIG. 23). As described above, each ID number for each corner and the estimated arrival time of each carriage cart CC are recorded. The present invention is not limited to the above embodiment.

As described above, according to the present invention, (1). Since water absorption from the back surface of the building board is effectively prevented,
The dimensional change of the whole plate is reduced. (2). Since the invasion of CO ₂ from the back surface of the building board is considerably prevented, carbonation and neutralization of the cement board are prevented. (3). As water is prevented from absorbing water from the backside of the building board, chlorine ions will not flow out from the inside, so when it is fastened to a steel frame foundation, oxidation of iron (generation of rust) is prevented. . (4) .Compared to the case of applying a sealer, the film strength (tear strength,
Since it has a high burst strength, etc., it suppresses the occurrence of scratches, cracks and chips (especially the actual part).

(5). Since the back sealer coating step and the subsequent dry operation step are eliminated, the energy cost can be greatly reduced and the total coating cost can be greatly reduced. (6). The construction method of fastening the building board to the steel frame foundation prevents squeaking noise of the building board. (7). In the construction method in which nails (or screws) are driven in from the surface of the building board to fasten it, the elastic layer of the closed cells protects the vicinity of the protruding portion of the nail, so rainwater is blocked to some extent. It becomes possible. As a result, it is possible to prevent rainwater from flowing around to the back surface of the plate much more effectively. (8). By forming the foam layer on the back surface, a certain degree of shock absorption is exhibited, and the phenomenon of fine cracking even when an external force is applied is considerably alleviated.
