Description

This device applies anti-corrosion coating to bolts, nuts, washers, and steel or joint auxiliary members around the washers that are arranged in a joint formed by joining steel and steel members together by bolt joining (industry) (This is called touch-up.)

By constructing a steel frame by joining steel members together with bolts and nuts and attaching a precast concrete plate to this to build a frame, or by sequentially joining steel materials by bolt joining In structures such as steel towers and bridges that are constructed while extending the structure, it is indispensable to carry out anti-corrosion painting after bolts and nuts are tightened.

Since the above rust-proof coating is applied after construction of the building at the construction site, mechanical installation such as spray coating is difficult due to restrictions on environmental issues such as air pollution. Because the nuts are dense, you have to rely on manual work with a brush. The number of joints in the structure, and hence the total number of bolts and nuts, is enormous. Conventionally, manual construction has required enormous man-hours. In addition, it is required for the operator to check the coating residue that is likely to occur on the dense bolts and nuts, etc. and repair the coating many times in order to clear the construction inspection, which is a major factor in reducing work efficiency. It has become.

Furthermore, in many cases, the rust-proof coating is a work at a high place, but the joints are difficult to maintain the work posture of the operator, for example, under the beam of a building or the bridge girder of the bridge. Since it is often arranged on a side surface or an overhanging oblique surface, painting with a brush consumes labor and inevitably lowers work efficiency. Although the idea of attaching a mark by putting a socket-like instrument on bolts and nuts has already been disclosed, it does not meet the purpose of the present invention because a method of spraying paint is used.

The problem to be solved in the present invention is to dramatically improve the work efficiency when performing touch-up as compared with conventional brushing. Moreover, it is to remarkably reduce the labor for touching up the bolts and nuts arranged at positions where it is difficult to maintain the position of the steel member's hook and the worker's working posture as viewed from the operator.

Furthermore, in order to be widely adopted in the civil engineering construction industry, construction tools that can improve work efficiency and reduce labor for such touch-up must be easy to provide in large quantities and at low cost.

According to the present invention, a handle, a saucer that is fixed to the handle and receives a rust-proof paint that hangs down during painting, and a thick-bottom cup-shaped impregnating material rises concentrically on the peripheral surface of the saucer. By using a novel touch-up construction tool including a paint-impregnated portion provided in close contact with the above, the above-described problem is solved. That is, the touch-up construction tool according to the present invention is
The main feature is that it includes a handle portion, a saucer portion, and a paint impregnated portion provided in close contact with the peripheral surface of the saucer in a concentric cylindrical shape.

According to the present invention, the cylindrical paint-impregnated portion is provided, so that the bolt-nut can be connected to the bolt even if the bolt and nut are fastened in the direction of gravity, such as up / down, left / right, front / back, or diagonal. By touching the bolts and nuts deeply until they reach the steel frame in the same direction, it can be touched up easily. Even if this reciprocating motion is repeated multiple times deeply and shallowly in the state of being covered in this way, the man-hour reduction and the labor reduction effect are remarkably large as compared with the conventional brush coating, and the work efficiency is remarkably improved.

According to the present invention, a bolt / nut arranged at the joint located on the lower surface of the steel frame with respect to the direction of gravity is provided by providing a saucer and concentrating a paint-impregnated part concentrically with the peripheral surface of the saucer. When the touch-up is performed, the dripping paint can be received by the tray portion, so that the quality of the work which is kept away from dirt and tightness is improved.

According to the present invention, joints disposed on the lower surface, outer surface, or overhanging slant surface of a building beam or bridge girder, which is difficult for the painter to maintain a working posture. When touch-up is applied, the paint loss during the work is reduced, the work discomfort is reduced, and the safety of the work is significantly improved.

The saucer part of the construction tool according to the present invention is a dish-like member having a concave part, and in general, a part of a shallow spherical surface is used for the shape, but a part of a conical surface or a spheroid surface is shallow. The top of a polygonal pyramid or the top of a quadrangular pyramid can also be used. The thickness of the tray portion may be a level that can maintain a strength that does not interfere with work.

The material of the tray portion is preferably as light as possible for the convenience of touch-up work, and is preferably low-cost in view of the fact that it is disposable after the work is finished. For example, croquetted wood, thinner-resistant synthetic resin, and the like are preferably used in consideration of incineration after disposal, but lightweight alloys such as aluminum can also be used.

The handle part according to the present invention is fixed vertically to the apex part of the convex part of the saucer part. The shape of the handle is preferably a circular tube for convenience of manufacture. However, a polygonal column shape and a square bar shape are also used for the purpose of stopping slippage due to sweat or solvent during work. The material of the handle part may be a member made of a different material as long as it can be fixed to the tray part. However, in practice, both may be integrally formed of a thinner-resistant synthetic resin by a plastic molding method. Alternatively, both may be integrally cut from the wood by locomotive processing.

The paint impregnation part according to the present invention is a member formed by forming an impregnating material into the shape of a thick-bottomed cup,
The inner diameter of the impregnated portion is determined so as to gently circumscribe the outer diameter of the bolt / nut to be touched up with the paint impregnated. The length of the impregnated part in the axial direction is such that when the work tool according to the present invention is put on the bolt and nut and the handle is pushed until the receiving part touches the tip of the bolt and nut, the steel frame around the washer is coated. It is preferable to have a length that allows a margin for the

The cup may have a cylindrical shape, but a shape having a slightly open edge in a trumpet shape is preferable because the steel frame around the washer can be easily painted. The thickness of the thick bottom may be such that when the impregnated portion is put on and pressed against a bolt / nut to be touched up, the remaining bolt portion can be wrapped after the nut is fully tightened.

When the construction tool according to the present invention is used, paint is put into a container such as a bucket, and the paint impregnation portion is immersed in the paint like a mop to contain the paint. The material of the impregnation part is a brush-like material formed by flocking the periphery of the saucer part in a circular shape, a woven fabric of natural fibers such as canvas, a nonwoven fabric of thinner-resistant synthetic resin, or a sponge-like synthetic resin high foam. preferable. However, in the case of a brush, the portion corresponding to the thick bottom of the cup needs to be supplemented with a sponge or non-woven fabric.

Examples of the synthetic resin high foam used for the touch-up construction tool according to the present invention include a crosslinked polyethylene high foam, a flexible polyurethane high foam, and the like.

FIG. 1 is a longitudinal sectional view illustrating an embodiment of a construction tool according to the present invention. A coating impregnated portion 2 in which a soft polyurethane high-foamed body is formed in a thick-bottom cup shape is closely attached to a saucer portion 3 having the shape of a spheroid surface portion so as to stand up from the saucer portion 3 with a urethane-based adhesive. is there.

In this case, the tray part 3 manufactured to various dimensions according to the size of the nut and the handle part 4 which may be of a uniform size are separately formed of hard polyurethane resin, and after the handle part 4 and the tray part 3 are bonded together The paint impregnation portion 2 is bonded to the tray portion 3.

The size of the construction tool according to the present invention is determined by the inner diameter of the paint-impregnated part, but in practice, several types of sizes are available to correspond to the sizes of bolts and nuts used in general structures. It becomes a construction tool widely used in the civil engineering construction industry. Since it is structurally simple, it is easy to manufacture and the manufacturing cost is relatively low, so it can be supplied in large quantities.

FIG. 2 shows the method of using the touch-up construction tool according to the present invention in order from left to right. The construction tool according to the present invention is easy to use as shown in the figure, and even if used by an unskilled worker, the touch-up construction can be ensured, so the reliability of construction quality control is high and neat. In spite of the increase, it is possible to deal with the labor mismatch problem with the aspect of lack of skilled workers.
