BACKGROUND OF THE INVENTION
In the construction of joint seal materials, gap fillers, and crack fillers used for civil engineering or construction work, the present invention does not contaminate workers' hands when constructing a fluid material before curing. In addition, it provides an economical and simple construction tool that is easy to dispose of, can reduce construction materials, and does not use a large-scale machine, that is, can contribute to reducing CO ₂ generation, which is an environmental problem. Is.
[0002]
[Prior art]
In civil engineering work and building construction work, there are many works for joint sealing, gap filling, and crack filling. There are various types of joint seals. For example, wide concrete pavement joints such as airfields, harbors, and roads, joints of waterways, reservoir joints, seawalls such as seawalls, breakwaters, and concrete secondary products such as box culverts. There are joints for three-dimensional concrete structures such as joints, and joints for waterproofing inside and outside buildings and houses.
Crack filling is observed in asphalt pavement, concrete pavement, concrete structures and the like.
[0003]
As a joint sealing method, joints such as concrete pavements with a large area are long and horizontal joints, and therefore, a fluid sealing material is injected using a special machine. In this type of machine, a large-scale machine having a storage part for a sealing material, a pump capable of adjusting the flow rate, and power for moving the pump is used.
These machines have the capacity of a daily work amount of, for example, 2000 to 3000 m or more. On the other hand, if there is only a slight extension of joints, it is suitable for such machines that cannot be easily carried. Absent.
[0004]
In joints with three-dimensional structures, fluid seal materials cannot seal joints that are vertical or inclined, so they are not fluid and use non-sagging seals. . As a construction tool for these sealing materials, there is a so-called caulking gun in which a nozzle is attached to the tip of a cylindrical sealing material container, and a material is pushed out from the opposite side by pulling a trigger. This caulking gun is prepared with a one-component type or a two-component mixed type sealing material that mixes the main agent and curing agent in advance, and is used after opening the lid of the gun and sealing the sealing material in the cylindrical container of this gun. are doing. In addition, there is also a type in which a one-pack type sealing material is wrapped in a soft resin film into a cylindrical shape, and one end is broken and put into a bag as it is in a cylindrical container of a caulking gun. Furthermore, instead of this caulking gun, a sealing material is sealed in a disposable cylindrical container in advance, a sealing film and a nozzle are attached to one side, and the other side can slide by hitting an extrusion plate. In some cases, a so-called cartridge with a bottom plate is used and this is applied with a dedicated cartridge gun. These caulking guns and cartridge guns have a simple structure, are inexpensive, and are suitable for small quantities. However, these instruments have no fluidity and are limited to sealing materials that are free of fluid, and the present situation is that there is no such simple instrument in fluidly sealing materials (self-leveling type).
[0005]
For large cracks, cracks are filled mainly by heating and melting rubber asphalt. A machine for this purpose is equipped with a kettle capable of melting the material, a burner for keeping warm, a fuel gas, and the like, and only a large amount of material can be melted at one time, and the machine itself becomes a large scale. In addition, since a large amount of fuel is consumed, a large amount of CO ₂ must be generated at the construction site, which causes environmental problems.
Moreover, since it must be heated and used each time, it takes time and at the same time costs and is not suitable for slight construction. Also, the room temperature type was very time-consuming because there was only a construction method in which about 300 ml of a bottle gun type filler in a cylindrical plastic container was stirred each time and filled manually.
[0006]
There are also one-liquid type and two-liquid types of fluid sealing materials, which are contained in sealed cans and plastic containers. The two-liquid type is used after mixing and stirring two liquids in advance. In order to install these materials to a certain distance without using a large-scale machine, crush the upper edge of the tin can and pour it into a beak, and then pour the sealing material into the joint, or use a caulking gun. Is applied, and the sealing material is poured into this and injected into the joint, which is extremely primitive.
[0007]
[Problems to be solved by the invention]
The present invention provides an economical simple sealing device that can easily and efficiently apply such a fluid sealing material.
In other words, there was no simple sealing device suitable for the construction of a relatively medium-sized construction that cannot be used with a large-scale construction, rather than a large-scale construction that uses a large-scale machine. . Moreover, there was no suitable apparatus which can inject | pour freely into the small crack among the cracks which generate | occur | produced in the target object. For this purpose, tin cans are used separately from the product containers, or caulking guns are applied, which increases the number of cans discarded after use, or requires cleaning of dirty equipment with a solvent. At the same time, it was necessary to dispose of the solvent.
In addition, the sealing material is put in a can or a plastic container that cannot be crushed, and it is necessary to discard these containers after use. Therefore, the need to reduce these wastes was also pressing.
Also, if there is only a small amount of material, it is convenient to carry and carry, but the quantity that can be installed at one time is very small, and it takes time and labor, and the work efficiency is reduced. As the amount of waste increased, the amount of waste also increased, and the disposal of containers was of course necessary.
[0008]
[Means for Solving the Problems]
The present invention relates to a plastic container for filling construction material such as a fluid sealing material or an adhesive, and a container that can be detachably attached to the container. The present invention relates to a simple construction tool for gap filling and crack filling, characterized by comprising an air type pump capable of discharging the construction material inside and controlling the air pressure.
[0009]
DETAILED DESCRIPTION OF THE INVENTION
In the present invention, in order to solve the conventional problems, first, the sealing material is sealed in a plastic container such as polyethylene (PE) or polypropylene (PP). This plastic container is a soft film container such as PE or PP, or a soft molded container, and is supplied in a special case or supplied as it is, and after use it is reduced in volume by crushing etc. And The special case may be made of plastic or the like, or may be disposable as a simple case such as a cardboard case, and the amount of waste can be reduced in terms of volume and weight as compared to conventional containers such as cans.
[0010]
However, the plastic container (hereinafter referred to as “poly container”) is made of soft plastic that can be easily crushed after use, and therefore cannot withstand high pressure. Usually, in order to discharge a material by air (air) pressure, it is necessary to use a very strong dedicated container. Therefore, the machine becomes large and inconvenient to carry.
In the present invention, a box-shaped holder is used, and a plastic container is loaded in the box-shaped holder so as to be able to withstand the air pressure by the air pump.
The shape of the holder is usually a rectangular box shape, but is not necessarily limited thereto, and may be an upright cylindrical shape.
[0011]
When the container is made of a soft plastic film, the plastic container is easily deformed and stored in the holder, so that the shape of the holder loading chamber can be rectangular or cylindrical. But you can. In order to load the poly container with the sealing material into the holder together with the dedicated case, the shape of the loading chamber may be a shape corresponding to the case. The holding tool may be opened and closed at the upper surface corresponding to the lid. However, in order to load a heavy plastic container with a sealing material, it is advantageous to open and close the side of the holding tool.
A notch is provided on the upper surface of the holder so that the opening of the plastic container protrudes and is held on the upper surface. The opening of the plastic container is held by the notch and is coupled to the air pump via a connecting member.
Therefore, even when the plastic container is made of a plastic film, the opening at the top of the container has a thick cylindrical shape so that it can be held by the notch in the upper surface of the holder, and the opening end projects into a flange shape. Good.
The cut portion provided on the upper surface portion of the holder may be circular or square as long as the opening of the plastic container can be held out, but preferably the upper surface portion of the holder is a slightly inclined surface, and the upper surface portion of the holder If the cut portion is U-shaped with the lower part opened from the side edge to the center, the opening of the poly container can be slid from the U-shaped open mouth of the cut portion toward the center of the upper surface of the holder. This is advantageous because it can be fixed.
[0012]
In the present invention, it is possible to prevent the plastic container from being excessively expanded by the air pressure fed into the container by the holder, and at the same time, prevent the wet sealant from being scattered. In addition, the air pump is provided with a pressure gauge, an air regulator, an air vent cock, and the like to control the pressure in the plastic container and the discharge amount of the sealing material.
The construction tool of the present invention can be a device that can be moved by placing each member such as a plastic container, a holding tool, an air pump on a carriage, and a necessary member for a hanging belt or a belt attached to a waist. It can also be held by an installation worker and operated.
Hereinafter, the present invention will be described with reference to the drawings, but the present invention is not limited to these examples.
[0013]
FIG. 1 is a block diagram showing an example of a simple construction tool according to the present invention. In the figure, 1 is a plastic container filled with a sealing material, 2 is a box-shaped holder, and 4 is an air pump.
The figure shows a state before the plastic container 1 is loaded into the holder 2. The plastic container 1 is inserted from the opening on the side surface of the holder 2, and the opening of the container 1 is inserted into the U-shaped cut 21 and fixed. As shown in the drawing, the upper surface portion 22 of the holder 2 is inclined so as to rise in the insertion direction of the container 1, and the mouth of the container 1 and the connecting member 3 are joined by simply pushing the container 1. The lower part of the air pump 4 is inserted into the container 1.
[0014]
An air compressor 8 is connected to the air pump 4 via a tube 5, an air regulator 6, and a pressure gauge 7, and a battery or a generator 9 that can drive the air compressor 8 is connected to this. Further, a discharge nozzle 13 is provided on the other tube of the air pump 4 via a discharge tube 11 and a flow rate adjusting valve 12.
The internal pressure of the container 1 is adjusted by the air regulator 6 so that the internal pressure during the operation can be managed by the pressure gauge 7 so that the internal pressure does not rise above a certain level. did. In addition, the container 1 was prevented from being excessively expanded due to pressure in the box-shaped holder 2.
Moreover, the air type pump 4 used APP-1 made from an aqua system which can discharge a material also at low pressure. The air pump 4 has an air vent cock, from which air can be extracted and can be interrupted before bursting, and at the same time can be used for cleaning.
[0015]
The cap part (opening part) of the container 1 is attached with a normal cap at the time of product shipment. When this is used, the cap can be connected to the air pump 4 simply by removing the cap, removing the inner plug and pushing it in. Replace with the connecting member 3 of the mold.
The container 1 is housed in a metal or resin box-shaped holder 2 together with the special case, and the opening is sandwiched and fixed in a cut portion 21 of the box-shaped holder 2. After the air pump 4 is coupled to the container 1 in this manner, the air compressor 8 is operated to press-fit air into the container 1, and the sealing material is discharged from the discharge nozzle 13 via the discharge tube 11 and the flow rate adjustment valve 12. Discharge to fill the sealing material.
[0016]
FIG. 2 shows another embodiment of the present invention in which the above-mentioned set of devices such as the holder 2, the air pump 4, the air compressor 8, the battery or the generator 9 is mounted on a carriage 10 with an adjuster. An operator moves the carriage to a required location by hand or the like.
FIG. 3 shows another embodiment in which the above-mentioned set of devices is attached to the hanging belt 14 and the waist belt 15 so that it can be easily attached to an operator and carried. In FIG. 2 and FIG. 3, the same components as those in FIG.
[0017]
When the simple construction tool of the present invention is used, it can be used as it is if the material in the container 1 is a one-component type. However, in the case of a two-component type, a separately prepared curing agent is used as the main agent in the container 1. Since it can be mixed by moving the sealing material inside as if it is put inside and shaking the container 1 by hand, it can also be used for a two-component type.
If the cap of the container 1 is replaced with the connecting member 3, it can be connected to the container 1 simply by pushing in the air pump 3, and then the connected compressor 8 is driven by a battery or a generator 9, and air is supplied to the container 1. I will send it.
Next, if the flow control valve 12 of the discharge tube 11 is opened after the internal pressure of the container 1 is increased, the sealing material is discharged from the discharge nozzle 13 in a constant amount, thereby sealing joints and cracks.
[0018]
The simple construction tool of the present invention uses simple power, is simple and lightweight, is easy to carry, and is safe because it can be operated at low pressure. Moreover, the quantity which can be constructed at once can be increased remarkably by changing the capacity of the container 1.
In the above description, a battery or a generator is used as a power source. However, when there is a normal power source such as an outlet near the construction tool, it is needless to say that these may be used.
[0019]
【The invention's effect】
Using the sealing device of the present invention, the filling construction time and construction quantity for pavement cracks were investigated. As the sealing device of the present invention, a tube 11 having an inner volume of 3000 ml, a pressure adjusted by an air regulator 6 of 0.03 MPa, an inner diameter of 12 mm, and a nozzle 13 were used. With this simple sealing device, a two-component liquid sealing material is applied to a joint with a width of 3 mm and a depth of 30 mm, and with a bottle gun type crack filler (360 ml, 8 pieces). The time and construction quantity were examined. The result is a table. 1.
[0020]

As described above, although the sealing device of the present invention is a simple and lightweight device, the construction time is fast and the work of mixing the filler is completed at once, and the operation is easy.
