[Technical field to which the invention belongs]

 The present invention relates to an apparatus for applying a liquid waterproofing agent by pressure-feeding a liquid waterproofing agent to a nozzle via a hose and spraying the liquid waterproofing agent toward an object to be sprayed.

[0002]

[Prior art]

 A method of spraying a liquid waterproofing agent to form a waterproof coating on the surface of a sprayed object such as a floor, a wall, a roof of a building, or the like, for waterproofing is often used. As a device for spraying liquid waterproofing agent, the liquid waterproofing agent in the tank carried into the desired location on the site is sucked out by a suction pump, sent to the spray gun through the hose, and held by the operator. The spray gun is generally sprayed from the spray gun to be operated. The hose part connecting the suction pump and the spray gun has a sufficient length and flexibility to enable the worker to work on site while moving as needed. In addition, the hose section is provided with an anticorrosion for protecting the hose so that it is not dragged on the work surface of the site by the movement of the worker or the swing of the spray gun, or is damaged when hitting the corner of an obstacle. Generally, the tape is wound. FIG. 4 is a cross-sectional view showing a conventional hose part structure. In FIG. 4, the hose portion H has a structure in which an insulating film F is interposed on the outside of the hose body 7, and an anticorrosion tape C is wound thereon and adhered and fixed.

[0003]

[Problems to be solved by the invention]

 However, in order to replace the anticorrosion tape, which has become severely damaged by dragging on the work surface at the site, the above anticorrosion tape must be peeled off from the outside of the hose body, which extends for several tens of meters. The troublesome work of re-applying a new anticorrosion tape must be performed. Although an insulating film is interposed between the hose body and the anticorrosion tape to make it easier to remove the anticorrosion tape, it takes time and effort to remove them all from the tens of meters of the hose body. There was a need for the development of appropriate technologies to improve efficiency.

The present invention has been made in view of the above circumstances, and has a cover for appropriately protecting a hose body to which a liquid waterproofing agent is pumped, and facilitates replacement of the cover. It is an object of the present invention to provide a construction device for a liquid waterproofing agent that can be used.

[0005]

[Means for Solving the Problems]

 The invention according to claim 1 is an apparatus for applying a liquid waterproofing agent, in which a liquid waterproofing agent is pressure-fed to a nozzle through a hose portion and sprayed toward a spraying target object, wherein the hose portion is A hose body to which the liquid waterproofing agent is fed under pressure, and an opening / closing part provided in a cylindrical shape outside the hose body so as to surround the hose body and extending along the longitudinal direction of the hose body. And a restraining member which is provided in a cylindrical shape so as to house the hose protection cover outside the hose protection cover and restrains the hose protection cover to prevent the opening / closing portion from being opened. It is characterized by comprising.

[0006] With such a configuration, the hose protection cover protects the hose body. When the hose protection cover is opened at the opening / closing section in the longitudinal direction, the hose protection cover is detachably attached to the hose body, and replacement work is possible. A restraint that restrains the hose protection cover from outside will prevent the hose protection cover from opening. That is, when spraying a liquid waterproofing agent using a spray gun, the hose is dragged by the movement of the worker holding the spray gun, the swing of the spray gun, etc., and the force such as bending and pulling is repeatedly applied to the hose. However, the binding member restrains the hose protection cover to prevent the opening / closing portion from being opened. This prevents the hose protective cover from being detached from the hose body and water from entering into the hose protective cover.

According to a second aspect of the present invention, there is provided an apparatus for applying a liquid waterproofing agent according to the first aspect, wherein the restraining member is made of a synthetic resin fiber that is knitted and knitted.

With such a configuration, the restraining member has flexibility and elasticity, so that the work of storing the hose protective cover becomes easy. Further, it is more preferable that the restraining member made of synthetic resin fiber has low contact resistance. According to such a configuration, the frictional resistance of the hose portion on a work surface such as a building roof is reduced, and the The parts are easy to slide, and the movement of workers is also easy.

According to a third aspect of the present invention, there is provided the construction apparatus for a liquid waterproofing agent according to the second aspect, wherein the restraining member cross-knits fibers arranged obliquely in a longitudinal direction of the hose portion. It is characterized in that it is formed in such a manner that it can expand and contract in the longitudinal direction of the hose part.

[0010] According to this invention, when the restraining member is elongated in the longitudinal direction by the pulling force, the dimension in the cross section direction is reduced, and as a result, the hose protection cover is tightened by the restraining member. This effectively prevents the opening and closing portion of the hose protection cover from being opened. For example, when the hose portion is dragged on a work surface such as a building roof, the restraint may be partially stretched due to contact resistance with the work surface. In this case, since the cross-sectional dimension of the stretched portion of the restraining material is reduced and the hose protective cover is tightened, opening of the opening / closing portion is prevented. Also, while the restraining material is dragged in a portion of the hose portion routed on the work surface in contact with the work surface, the restraint material is lifted in a portion where the spray gun held by the worker stands up and the like. Since it is pulled in the longitudinal direction, the cross-sectional dimension is reduced, and the hose protective cover is tightened. Therefore, even though the part raised up to the spray gun is a place where deformation due to bending force is repeatedly applied, opening of the opening and closing part is effectively prevented by tightening the hose protective cover with the restraining material. Is done.

[0011]

[Embodiment of the invention]

 Hereinafter, a construction apparatus for a liquid waterproofing agent according to an embodiment of the present invention will be described with reference to the drawings.

FIG. 1 is a view showing an apparatus S for applying a liquid waterproofing agent according to the present invention (hereinafter also referred to as a waterproofing apparatus), and FIG. Is shown.

The waterproof construction apparatus S shown in FIG. 1 is placed on the roof of a building T which is a site for waterproof construction, for example. The waterproofing construction device S includes, for example, storage tanks 1 for storing two types of liquid waterproofing agents A and B (for example, one is a main agent containing an isocyanate component and the other is a curing agent containing a polyol component) which cures when mixed. , 2, suction pumps 3, 4 for sucking each of these two types of liquid waterproofing agents A, B from storage tanks 1, 2 via hose section H, and liquid waterproofing agents A, B are mixed and ejected. Spray gun G.

As shown in FIG. 2, the hose portion H includes hose bodies 5 and 6 for transporting the waterproofing agent to which the liquid waterproofing agents A and B are respectively fed under pressure, and a tube so as to enclose the hose bodies 5 and 6. A hose protection cover 10 provided on the side and provided with an opening / closing portion 8 extending along the longitudinal direction of the hose bodies 5 and 6, and the hose protection cover 10 is housed outside the hose protection cover 10. And a restraining member 20 for restraining the hose protection cover 10 to prevent the opening / closing portion 8 from opening.

The hose protective cover 10 is formed of a material having flexibility and surface smoothness (for example, vinyl chloride), and has a strip-like sheet-like shape when opened. Zippers 11, 11 are provided on both sides in the longitudinal direction of the band shape, the both sides are fitted so as to wrap the hose bodies 5, 6 so as to form a tube, and the zippers 11, 11 are further closed. The opening / closing part 8 is formed by this.

The constraining member 20 is formed by interweaving fibers that spirally turn in opposite directions. At first glance, it is as if fibers arranged obliquely in the longitudinal direction are interwoven. It is configured. The fibers constituting the restraining member 20 include, for example, synthetic resin materials such as plastic, carbon Keppler vinyl chloride, vinyl chloride with cotton calico, vinyl chloride containing polyester, and glass fibers.

In the waterproof construction apparatus S shown in FIGS. 1 and 2, even if the hose portion H is dragged with the progress of the waterproof construction work, the hose protection cover 10 is connected to the hose so that the hose bodies 5 and 6 are not damaged. Protect the body 5,6.

A restraining member 20 for restraining the hose protection cover 10 from the outside prevents the hose protection cover 10 from being opened. That is, in the spraying of the liquid waterproofing agent using the spray gun G, the hose H is dragged, bent, pulled, or the like by the movement of the worker M holding the spray gun G or the swing of the spray gun G. Although the force repeatedly acts on the hose portion H, the hose protecting cover 10 is restrained by the restraining member 20 to prevent the opening / closing portion 8 from being opened. Thus, detachment of the hose protection cover 10 from the hose bodies 5, 6 and ingress of water into the hose protection cover 10 are prevented.

Further, when the hose portion H is dragged on the work surface O such as the roof of the building T, the restraining member 20 is partially stretched due to the contact resistance between the hose H and the work surface O. Is reduced and the hose protection cover 10 is tightened, so that the opening and closing portion 8 is prevented from being opened.

In the hose portion H routed on the work surface O, the restraining member 20 is dragged at a portion P in contact with the work surface O, while the spray gun G which the worker M holds is started up. Since the restraining member 20 is pulled in the longitudinal direction at the portion Q and the like, the cross-sectional dimension is reduced, and the hose protective cover 10 is tightened. Therefore, the opening Q of the opening / closing section 8 can be opened by tightening the hose protection cover 10 with the restraint member 20 even though the portion Q that has been raised up to the spray gun G is a place where deformation due to bending force is repeatedly applied. Effectively prevented.

In addition, the frictional resistance of the hose portion H on the work surface O, such as the rooftop of the building T, is reduced by using the restraint member 20, and the hose portion H slides easily on the work surface O. The movement of the worker M is also facilitated. Not only the frictional resistance between the work surface O and the restraining member 20 but also the frictional resistance between the hose protective cover 10 and the restraining member 20 is small. This is because the hose protective cover 10 has surface smoothness and the restraining member 20 is a synthetic resin fiber, so that the contact area with the hose protective cover 10 is small. In this manner, the movement of the hose portion H accompanying the spraying operation is facilitated, and the force applied to the opening / closing portion 8 is reduced, so that the opening is prevented.

When the hose protective cover 10 and the restraint member 20 are damaged due to long-term use, replacement work is performed as follows. First, the restraining member 20 is removed from the hose protection cover 10. Next, the hose protection cover 10 is opened at the opening / closing section 8 in the longitudinal direction by removing the zippers 11, 11. Remove the hose protection cover 10 from the hose bodies 5 and 6, and replace it with a new unused hose protection cover 10 prepared separately. The new hose protection cover 10 is attached by tightening the zippers 11, 11 at the opening / closing section 8 after being formed into a tubular shape so as to enclose the hose bodies 5, 6. Finally, the separately prepared new restraint member 20 before use is put on the newly attached hose protection cover 10, and the operation is completed.

Here, the work of removing and covering the restraining member 20 on the hose protection cover 10 is performed promptly because the friction between the hose protection cover 10 and the restraining member 20 is small. The work of attaching and detaching the hoses to and from the hose bodies 5 and 6 can be easily performed by opening and closing the zippers 11 and 11.

According to the waterproof construction apparatus S shown in FIGS. 1 and 2, the hose protection covers 10 can protect the hose bodies 5 and 6, and at the same time, when replacing the hose protection covers 10, the zippers 11 and 11 can be used. The opening / closing unit 8 can be opened and closed by an operation of removing and tightening 11, and the hose protection cover 10 can be easily attached to and detached from the hose bodies 5 and 6. Further, since the zippers 11 and 11 are used, the waterproof property can be easily realized in a place where there is a puddle or the like.

Since the outer side of the hose protection cover 10 is restrained by the restraint member 8, it is possible to prevent the zippers 11, 11 from opening even if a force is applied to the opening / closing portion 8 during operation. Further, since the fibers arranged obliquely in the longitudinal direction are cross-knitted, the portion of the hose H to which the force is easily applied is tightened, and the opening and closing portion 8 can be prevented from being opened. In addition, the structure in which the synthetic resin fibers are mixed and knitted allows the restraining member 20 to be easily attached to and detached from the hose protection cover 10.

In the above embodiment, the zippers 11, 11 are provided in the opening / closing section 8, but a configuration in which a hook-and-loop fastener is provided instead of the zipper may be used. If the hose protective cover 10 is not required to be watertight, a hook or the like may be used instead of the zipper or the cotton fastener. In short, it is only necessary to provide an opening and closing means that can be easily attached and detached. Further, the number of hose bodies stored in the hose protection cover 10 is not limited to two, but may be any number, and an electrical cable or the like may be used instead of the hose.

In addition, in the above embodiment, an example in which the roof of the building T is waterproofed has been described. However, it goes without saying that the place where the waterproofing is performed is not limited to the roof.
