Abstract

PURPOSE:To continuously manufacture favorable quality reinforced foamed concrete products by a method wherein cement slurry, which is prepared by pouring a large amount of air bubbles, is placed in concrete forms and, after that, sent in a curing chamber for curing and surface-finished after curing and finally demolded. CONSTITUTION:A concrete form 12, in which cement slurry is filled, is shifted on the first line 1 in its direction of proceeding so as to level the surface of the slurry. Next, the concrete form 12, which contains the surface-treated slurry, is shifted on the first line toward its tip side so as to proceed toward the other end side of one of curing chambers 13. At the other end side of the curing chamber 13, slurry-containing concrete forms 12... are piled up in a plurality of layers so as to be enclosed under the condition that a lid 23 is seated on the uppermost layer of the concrete forms in order to keep the temperature of the slurry in the concrete form 12 at about 60 deg.C. Thus, the hydration reaction is accelerated so as to harden the slurry at its early stage. By surface-finishing the slurry again at the entering or leaving of the concrete form to or from the curing chamber 13, the high quality concrete product is obtained.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention is particularly applicable to cement slurry obtained by injecting and kneading a large amount of foam into cement mortar or cement paste, and pouring it into a formwork and curing it. The present invention relates to a continuous manufacturing system for reinforced foamed concrete products for manufacturing reinforced foamed concrete products.

[Prior art] Conventionally, for example, a large amount of foam is injected into cement mortar or cement paste, and the resulting cement slurry is poured into a formwork to produce foamed Roncrete products such as concrete plates. This is generally known.

However, there has been no continuous production system that can rapidly produce foamed concrete products such as concrete plates in large quantities and with good product quality.

[Object of the Invention] Thus, the present invention has been devised in view of the above-mentioned conventional problems, and in particular, a cement slurry produced by injecting a large amount of foam is poured into a formwork, and the cement slurry is poured into a curing chamber. To provide a manufacturing system for feeding reinforced foamed concrete products, curing them, molding them, and producing reinforced foamed concrete products continuously, rapidly, in large quantities, and while maintaining good quality of the products.

[Structure of the Invention] The continuous production system for reinforced foamed concrete products according to the present invention performs mold-setting, cleaning, and release agent application work at one end of a first line, which consists of a plurality of moving lines that advance in a predetermined direction. a step of processing anchors to be reinforced within the formwork in a second line that advances toward the first line from a direction different from the first line and intersects the first line; A process of arranging reinforcement in the formwork after assembling the anchors, a process of filling the formwork that has gone through the above process with cement (~slurry) and finishing the surface, and a process of applying the slurry filled formwork that has gone through the above process. The formwork is stacked in multiple tiers and sent into the curing chamber from one end of the curing chamber, passed through the curing chamber and moved to the other end, and the process of surface finishing again, and curing from the other end of the curing chamber. A step in which the formwork containing the slurry is sequentially taken out, placed on the first line and demolded to take out the concrete product, and the formwork after demolding is moved to the process of forming, cleaning, and applying a release agent. It is characterized by sequentially repeating the steps of:

[Embodiment of the Invention] The present invention will be described below based on an embodiment shown in the drawings.

In the drawings, reference numeral 1 designates a first line consisting of two moving conveyor lines 2.2 traveling in the same direction.

On the proximal end side of the first line 1, the conveyor lines 2.2 are divided into respective moving conveyor lines 2.2, and about four workers work on forming the formwork 12, cleaning it, and applying a release agent.

Here, the molding of the formwork 12 is carried out by first setting up four end boards 21... having a substantially rectangular shape on the outer peripheral edge of the bottom plate 20, and then forming the frame by setting up the end boards 21... of the bottom board 20 and the end boards 21... This is done by concatenating.

After the mold is assembled, the inside of the mold 12 is cleaned, and a release agent is applied to the inside of the mold 12 to facilitate demolding after filling with slurry in a later step.

Note that cleaning the inside of the formwork 12 involves blowing away dust by jetting air, and at this time, there is a risk that dust may fly around. Therefore, "cleaning" in this process
is preferably carried out in a shielded room.

A second line 3 is also provided which is installed in a different direction from the first line 1, advances toward the first line 1, and is configured to intersect with the first line 1.

On the proximal end side of this second line 3, a step of processing the anchors 4 arranged within the formwork 12 is performed.

That is, the anchors 4 are processed into a substantially grid shape on the base end side of the second line 3, and the processed anchors 4 move on the second line 3 in the direction of the intersection with the first line 1.

Then, at the intersection of the first line 1 and the second line 3, a step of arranging the anchors 4 in the formwork 12 after the mold-setting, cleaning, and release agent application operations are performed is performed.

Although not shown, the reinforcement work may be performed at a completely different location or by processing the anchors 4 in advance and bringing the anchors 4 to a position near the first line 1.

The formwork 12 on which the reinforcement work for the anchors 4 has been performed in this manner further advances in a predetermined direction of movement on the first line 1, and is moved to a certain location where the mixer device 5 is installed.

The mixer device 5 is configured as a large device with multiple stages of cement mixers installed on a pedestal 22 installed across the first line 1, and the top stage has water, cement,
Respective storage boxes 6 containing other additives
．． 7.8 is installed, and the mixture is fed from the storage box 6.7.8 into the lower first mixer 9 at a predetermined mixing ratio and kneaded for a predetermined time.

Then, a portion of the cement paste or cement 1 to mortar that has been kneaded for a predetermined time is put into either the second mixer 10 or the third mixer 11 located roughly below and kneaded again. The kneading time at this time is approximately the same as the mixing time of the first mixer 9.

In addition, when producing slurry for reinforced foamed concrete, a large amount of foam produced by a foaming device (not shown) is transferred to the second mixer 10 or the third mixer 11 during the mixing operation. It is injected into mixer 10 or third mixer 11.

The cement slurry mixed by the second mixer 10 or the third mixer 11 flows through the formwork 12 on the first line 1.
The inside is filled through an agitator.

As shown in the figure, the filling operation can be carried out by one person on each of the left and right lines on the first line 1.

The formwork 12 filled with the cement slurry moves roughly along the first line 1 in its advancing direction, and the next step, the surface treatment of the slurry filled in the formwork 12, is performed.

The surface treatment step is to flatten the surface of the slurry filled in the formwork 12, and is carried out in the movement line 2 in the first line 1.
．． 2, each of which is usually performed by a single person.

Next, the surface-treated slurry-filled formwork 12 roughly moves along the first line 1 toward its tip, and from the tip, changes its path of movement in a direction approximately perpendicular to the first line 1 (curving ) and move toward the other end of the curing chamber 13.

Then, at the other end of the curing chamber 13, the formwork 1 containing the slurry is
2... are stacked in multiple tiers (for example, about 4 tiers),
A lid 23 is placed on top of the uppermost formwork 12 to seal it.

By the way, this formwork 12 is made of a heat-insulating material, so that the temperature of the slurry inside the formwork 12 can be maintained at around 60°C, which accelerates the hydration reaction and hardens the slurry at an early stage. I can do it.

A high-quality concrete product having a predetermined strength can then be extracted.

From the other end of the curing chamber 13, the molds 12 stacked as described above slowly enter the curing chamber 13.

By the way, when entering the curing room 13 or curing room 1
If the surface is refinished when exiting from step 3, a higher quality concrete product will be obtained.

In the curing chamber 13, the molds 12 move at low speed from the other end of the curing chamber 13 to one end, and when the formwork 12 stacked in the entire longitudinal direction of the curing chamber 13 enters, the curing occurs. The leading slurry-filled formwork 12 is sent onto the first line 1 from one end of the chamber 13.

Next, when the slurry-containing formwork 12 that has left the curing chamber 13 as described above is installed on the base end side of the first line 1, it is further moved in the direction of movement of the first line 1 and is placed on the first line 1. Demoulding work is performed at predetermined locations, and the concrete product is removed.

After this demolding work is performed, the demolded formwork 12 is again subjected to mold assembly, cleaning, and release agent application work on the base end side on the first line 1, and then sent to the next process. Become.

In this way, these plural steps are repeated in sequence, and reinforced foamed concrete products of particularly good quality can be manufactured continuously, rapidly, and in large quantities.

[Effects of the Invention] Thus, the continuous production system for concrete products according to the present invention has the above configuration.

The continuous production system for concrete products according to the present invention can continuously, quickly, and in large quantities produce a production system that pours cement slurry into formwork, sends it to a curing chamber for curing, and then demolds it. Moreover, it has the excellent advantage that it can be manufactured while maintaining good quality, and that particularly reinforced foamed concrete products can be provided at low cost.
