備とする事に成功した。(Operation) This invention effectively utilizes the existing equipment of an immediate demolding concrete product manufacturing plant. In other words, not only the process of forming the concrete part of the target product using a formwork, but also the process of forming the buffer layer and joining it with concrete, use the same filling method and pressing means as concrete, and the above-mentioned compression forming and joining process. conduct. In other words, the elastic material that becomes the buffer layer is in the form of granules or fragments, which can flow as nodules and have a viscosity that can be compressed so that when compressed, the materials can be bonded to each other and the material and concrete. This makes it possible to apply the same filling means as conventional hardened concrete, and it also makes it possible to press the concrete in the formwork using a press for pressurizing the concrete. As a result, by simply adding a small amount of equipment to the existing equipment of the concrete product mass production factory, we were able to successfully create mass production equipment for concrete products with a buffer layer.
その製品の緩衝層は、粒か断片の集合圧着体
で、従来技術のように空隙に接着液を充填してコ
ンクリート層との接着をはかるものでないから、
一般に多孔質、透水性が保たれ、舗装板等に好適
である。 The buffer layer of this product is a compressed aggregate of particles or fragments, and unlike the conventional technology, the gap is not filled with adhesive liquid to bond it to the concrete layer.
It generally maintains porous properties and water permeability, making it suitable for paving boards, etc.

と時間で養生するのである。 The concrete with the buffer layer filled and crimped into the formwork is either immediately removed from the mold or sent together with the formwork to a curing field to harden the concrete layer, depending on the slump value of the concrete and the properties of the elastic material crimped part. The curing is performed at a temperature and time that promotes the bonding strength of the elastic material crimped portion.

える等の手段をとれば容易に脱型できる。 The adhesive force between the inner surface of the mold and the elastic material layer during immediate demolding is still weak, and even when demolding after curing, the elastic material is in the form of particles or fragments, so it does not harden like when liquid material hardens. The mold can be easily demolded by applying a demolding agent to the inner surface of the mold in advance or by applying vibration to the mold during demolding without causing any adhesion.

There is a method of reversing the formwork.

A mixer equipped with a metering and feeding device for each material for supplying buffer materials, a parent hopper and a sliding hopper for receiving the kneaded materials have been newly added to the equipment of a conventional instant demolding concrete product manufacturing factory, and concrete hardening and sliding hoppers have been newly added. We proposed a concrete product manufacturing device with a buffer layer that makes the most effective use of existing equipment by reusing or creating a new curing field that simultaneously hardens viscous liquids, etc.

We present a method to prevent the material from hardening in the parent hopper by adding and mixing these hardening agents to the buffer material just before it is introduced into the formwork. By performing the mixing in the supply path by the screw feeder of the material supply device, we have presented the simplest and most effective means of uniformly mixing the hardening agent while propelling the required amount of material just before feeding.

したものである。 In this embodiment, an instant demolding type concrete product forming apparatus using hardened concrete is used as is, and a new parent hopper 5' for buffer material G, A sliding hopper 4' is added. The press device 3 and the vibration device 2 attached to the formwork 1 are already installed, and the formwork 1 is of a type that allows concrete products to be demolded downward. The formwork bottom plate 1a is supported and driven by a lifting cylinder 7, and after filling with concrete, when the bottom plate 1a is lowered to the position indicated by the chain line in FIG. The equipment was used as is.

れゝば固まり、養生により強い結合が得られる。 To explain the process in order, first, each parent hopper 5,
Materials will be put into 5'. Ordinary hardened concrete is poured into the parent hopper 5 from the mixer 5a. The mixer 5'a, which feeds materials into the newly added parent hopper 5', mixes granular or fragmented elastic material (urethane chips), powdery granular elastic material (lime carbonate), and viscous liquid or viscous powder (urethane resin liquid).
Each metering device g, p, v is attached.
When the mixture is fed from these feeding devices into a mixer 5'a according to the composition described below and mixed, it becomes a mass with many voids and has fluidity similar to concrete, but it hardens when compressed and a strong bond is obtained by curing.
なお弾性素材はゴム、合成樹脂のいずれかにな
るが、その粒又は断片に、押付ければ接合できる
圧着性を与える手段は、加熱又は化学処理により
素材自身に粘性を与える方法と、外面に粘性被膜
を付ける方法とある。 The elastic material can be either rubber or synthetic resin, but there are two ways to give the particles or pieces the compressive properties that allow them to be joined by pressing them: one is to make the material itself viscous through heating or chemical treatment, and the other is to make the outer surface viscous. There is a method of applying a film.
いずれの方法による場合も、流動性と粘性とい

条件を課せられるが、粘性と称しても、圧縮され
た場合だけ固着する程度でよい。当初、固着力が
弱くても、その後、養生で強められゝばよいので
ある。 In either method, rather difficult conditions are imposed, such as having to appropriately combine the contradictory properties of fluidity and viscosity, but even if it is called viscosity, it only needs to be fixed when compressed. Even if the adhesion is weak at first, it can be strengthened through curing.
流動性を高めるには、素材周面に液分を多くす
るとは限らない。乾燥に近い状態で、流動中の相
互接触であは粘着せず良好な流動性を保つが、強
い圧着力で固着するようにしてもよい。 In order to increase fluidity, it is not always necessary to increase the amount of liquid on the surrounding surface of the material. In a near-dry state, when they come into contact with each other while flowing, they do not stick and maintain good fluidity, but they may be fixed by strong pressure.

で、樹脂液を増せば流動性が増し、石灰はその逆

性、圧着性を加減でき、実験的に最適配合を決め
やすい。 In the above example, a coating made of a viscous liquid (urethane resin) and inelastic powder (lime carbonate) is applied to the material.Increasing the resin liquid increases fluidity, and lime has the opposite effect, so Fluidity and compressibility can be adjusted by adjusting the distribution, making it easy to determine the optimal mixture experimentally.
さて、両側の親ホツパー5,5′にコンクリー

の構造である。 Now, after putting concrete C and buffer material G into the main hoppers 5 and 5' on both sides to create the state shown in Fig. 1, in this embodiment, first, as shown in Fig. 2, the concrete side sliding hopper 4 is placed in the formwork 1. Proceed upward. The sliding hopper 4 slides on the fixed sliding plate 9 at the height of the upper edge of the formwork 1, and during the movement, the exit of the parent hopper 5 is
This is a well-known structure that is closed by a horizontal closing plate 10 attached to the rear.

と同時に、コンクリート内部の空隙、型枠の隅々
等にコンクリートがむらなく満たされる。 FIG. 2 shows the state in which the concrete C in the sliding hopper 4 has fallen into the formwork 1 and its surface has been made almost horizontal either by the vibration device 2 alone or with the help of the press device 3. When the formwork 1 is vibrated by the vibrating device 2, the surface of the poured concrete C is leveled, and at the same time, the voids inside the concrete and every corner of the formwork are evenly filled with concrete.

りやゝ多く摺動ホツパー4′に入るようにしてい
るので、その摺動ホツパー4′を復帰させる際、
余剰分をかき取り、表面を平滑にする。 Then, when the sliding hopper 4 is returned to its original position and the sliding hopper 4' on the opposite side is advanced onto the formwork 1, the cushioning material G falls onto the concrete C in the formwork 1 as shown in FIG. Since the formwork 1 is vibrated by the , it spreads flatly and forms an elastic material layer, similar to concrete. In reality, slightly more cushioning material G than required enters the sliding hopper 4', so when returning the sliding hopper 4',
Scrape off the excess and smooth the surface.

ようにするとよい。 Then, the press device 3 is operated to press and compact both materials in the formwork 1 with the press plate 3a. During this time, it is preferable to apply vibration to the formwork 1 so that the granular or piece-like elastic materials can be assembled without any voids and the maximum crimping area can be obtained.

るとよい。 Then, when the force of the lifting cylinder 7 supporting the formwork bottom plate 1a is loosened, the concrete C layer and the cushioning material G layer integrated within the formwork 1, in other words, the product M It is sandwiched between the press plate 3a and the mold bottom plate 1a and is pushed out downward. The press plate 3a is returned upward, and the extrusion cylinder 8 transfers the product M onto the conveyor 6, which conveys the product M to a curing area. The process from demolding to curing remains the same as before. The curing conditions are determined so as to both harden the concrete and increase the joint strength of the crimped portion of the elastic material. The urethane resin liquid that makes up the elastic material coating layer in this example will harden even if left at room temperature in a curing field, but since it has thermosetting properties, it is best to cure it at a high temperature that can also be used for concrete to accelerate hardening.
こうして得られた製品Mは、ウレタンチツプ団

板になる。 The product M thus obtained is a concrete paving board with a porous buffer layer in the form of compressed and aggregated urethane chip agglomerates. This porous buffer layer becomes water permeable unless the pressing pressure is excessively high, so if the concrete that forms the main body of the paving board is made of well-known water permeable concrete, the paving board will have both buffering properties and water permeability.

もつ透水性緩衝舗装板となる。 In addition, if the concrete layer is sufficiently hardened using a press plate 3a shaped to form water guide grooves on the upper surface of the concrete filled in the formwork 1, and then an elastic material layer is built on top of it, as shown in Fig. 5. This results in a water-permeable buffer pavement board having water guide grooves 11.

する事ができる。 In the above embodiment, the hard concrete buffer material with a low moisture content was pressed, so the concrete layer and the buffer material layer could be joined relatively easily. However, if concrete with a high moisture content was poured, it would become somewhat troublesome. However, recently, water-resistant adhesives have been developed, and if used as a viscous liquid, they can generate a certain degree of bonding force even within the formwork, making it possible to create a sufficiently strong bond in a curing field.

もよい。 In addition, as a means to strengthen the bond between the concrete layer and the buffer material layer, a pressure bonding agent layer such as a polyester resin may be inserted between the two layers. This is equivalent to a primer in road paving work.
A strong joint between the two layers is created by adding a mediating agent injection step between the steps of forming the concrete or buffer material layer on the formwork described above, and providing a mediating layer of appropriate thickness between the two layers. In addition, a hydrophilic polymer may be mixed into the concrete in advance to improve adhesion.

させるようにしている。 No matter which method is used, mucus adheres to the inner surface of the formwork 1 at the portions that come into contact with the buffer material layer and the sprayed mediator, and when left to stand, this hardens. Therefore, in this embodiment, when pressing down the press plate 3a to demold the product M, the periphery of the press plate 3a scrapes off the mucus adhering to the inner surface of the form 1 and allows it to seep into the periphery of the product M. .

凹凸が種々、考えられる。 When creating slopes and grooves 11 on the upper surface of the lower concrete layer as shown in FIG. 5, it is preferable to insert a special push plate from the side under the press plate 3a. Furthermore, if the press plate 3a has a corrugated surface, the upper surface of the buffer layer is corrugated to prevent slippage, and at the same time, the upper surface of the concrete layer is also corrugated to increase the bonding area with the buffer layer and increase peeling resistance. Various effective irregularities other than waveforms can be considered.
上記実施例は、型枠1へまずコンクリートを入
れてから緩衝素材る入れたが、順序を逆にすれば
コンクリートが自重と振動とで、弾性素材の間隙
に入込みやすい。 In the above embodiment, the concrete was first poured into the formwork 1 and then the buffer material was poured, but if the order was reversed, the concrete would easily enter the gaps between the elastic materials due to its own weight and vibration.
しかし、コンクリートCを先に投入した場合の
ように、型枠1の底部に平らに緩衝素材Gを敷く
には、単に振動だけでなく、プレス板3aその他
の応援が必要になる。 However, in order to spread the cushioning material G flatly on the bottom of the formwork 1, as in the case where the concrete C is poured first, not only vibration but also support from the press plate 3a and other supports are required.
弾性素材の材質にもよるが、弾性素材だけを多

すると容易に改善される。 It depends on the material of the elastic material, but if there are problems such as a buffer layer made of porous elastic material being too soft or easily falling off when kicked by shoes,
This can be easily improved by mixing the above-mentioned powdery non-elastic material, such as lime carbonate.

層を付ける場合である。 In addition, instead of demolding the plate-shaped product to the bottom (or top) of the formwork as in the example shown in Figure 1, if the product is a block, the formwork is flipped 180 degrees and released by gravity. Make a mold. This is the case when a buffer layer is attached to the surface of the block.

The formwork support mechanism 13 is equipped with a rotating pallet support 15 for placing a surface pallet 14 and lowering it into the opening of the formwork 1, and moving it from the solid line position to the chain line position in the figure.

と同様である。 While the pallet receiver 15 is vibrated by the vibrating device 2 on the back side, the cushioning material G is evenly dropped onto the pallet 14 by the supply conveyor 16 that moves back and forth. When the filling of concrete into the formwork 1 is completed, the conveyor 16 is withdrawn, the pallet receiver 15 is rotated, the surface pallet 14 is placed face down on the upper surface of the formwork 1, and the pallet receiver 15 is immediately returned to its original position. Then, the press plate 3a is lowered, and the buffer material G is pressed and crimped onto the upper surface of the concrete C from above the surface pallet 14. After returning the press plate 3a upward, the chain wheel 12 is turned to reverse the formwork 1, and the surface pallet 15 is
The product M with the mark is dropped downward as shown by the chain line to remove it from the mold. Then, this is placed on a conveyor, sent to a curing field, and when it has properly hardened, the process of peeling off the surface pallet is the same as in the conventional method in which mortar is placed in the surface pallet.

Fig. 7 shows an example of the product, and Fig. 8 shows the main parts of the manufacturing equipment. In this embodiment, a common cushioning material G layer is pressed onto 16 paving stone blocks C. As shown in Fig. 8, a modified formwork is constructed by simply adding a common outer frame 1b for forming a layer of buffer material G common to each block to the upper surface of the formwork 1 for simultaneously molding a plurality of adjacent paving stone blocks C. It is.

成分のその後の硬化を促進する。 In the embodiment shown in FIG. 9, when a mixture of a granular or piece-like elastic material, a granular inelastic material, and a viscous liquid or viscous powder is used as the material for the buffer layer, a hardening agent for the viscous liquid or viscous powder is used. It has a device that supplies the material either by dripping or spraying onto the material just before it is placed in the mold, immediately spreads and mixes it evenly over the entire material, and then drops it into the mold. In this embodiment, the present invention is applied to the equipment shown in FIG. 1, and the only difference is that there is a material measuring chamber 19 between the buffer material G parent hopper 5' and the sliding hopper 4', and shutters above and below it. mechanism 20, 20',

These are the dropping device 24 and the like. After closing only the lower shutter 20' of the measuring chamber 19 and receiving the material G from the parent hopper 5' into the chamber, closing the upper shutter 20 and opening 20', the required amount of material G is delivered to the feeding path 22.
falls. When the screw feeder 21 is driven, the material G advances to the outlet, but when the curing agent is dripped from the dripping port 23, the screw blades spread and mix it throughout the material G, so that it slides from the outlet. When it falls into the hopper 4', it penetrates evenly and promotes the subsequent hardening of the adhesive component.

けるのもよい。 Note that this invention in which a curing agent is supplied to the buffer material immediately before it is filled into the mold, and the screw feeder performs diffusion mixing and propulsion at the same time is not limited to the method of feeding the material into the mold via a sliding hopper. It goes without saying that it may be directly poured into the formwork from the screw feeder. Furthermore, since the material is dropped continuously in small amounts from the screw feeder, it is well known that the screw feeder itself drops the material while moving the side that receives it, so that the material is piled up in one place. It is also good to avoid.
