Description

  The present invention relates to a joint staking tool for use in sieving joints, for example, before and / or after painting of an outer wall material of a building.

  Conventionally, there is JP 2000-70835 A as a technique in such a field. As described in this publication, since ALC panels (lightweight cellular concrete wall panels) are more porous than concrete, they are superior in lightness and heat insulation properties. For example, it is widely used as a construction material for outer walls, verandas, parapet structures and the like. Conventionally, surface coating methods for ALC panels include spray coating methods using a spray gun, and ironing methods using rollers, brushes, and the like. In other words, the surface of a general ALC panel has rough and fine bubbles, and when painting, the paint is not sufficiently filled in the bubbles by ordinary spray coating (especially the undercoating stage). Problems such as defects and insufficient waterproof performance occur. Therefore, in addition to spray coating, it is common to combine roller hanging and brush ironing. Moreover, in order to improve the designability, the ALC panel is provided with a line-type decorative joint or a square-type decorative joint, and since these decorative joints are formed by cutting grooves, other decorative parts on the panel are provided. There are more bubbles than the part, and it is necessary to carefully fill the paint. The joint is concave, and it is difficult to reach the joint bottom just by rolling on the surface, and ironing with a raster brush is required. The joints do not have to have a large amount of coating, and if the amount of coating is accumulated on the joints and the coating amount becomes excessive, it tends to lead to poor appearance and cracks in the coating film. Therefore, at the joint, ironing with a brush is performed, and it is necessary to remove excess paint.

JP 2000-70835 A

  However, in particular, joints for improving the design of the ALC panel are provided at a substantially constant interval, but there are various types, and some of them are provided in combination with vertical and horizontal at a fine joint pitch. In such a panel, it takes a lot of labor and time to perform the ironing operation with one joint brush. Also, when ironing with a single joint brush, the handle tends to lie down in a direction perpendicular to the direction in which the brush is squeezed. And lack of paint tends to occur.

  SUMMARY OF THE INVENTION An object of the present invention is to provide a joint squeezing tool that improves the efficiency of squeezing joints with a brush and ensures that squeezing is performed.

And are screwed into first female screw portions 13a and 14a sandwiched between one end of the second screw portion and second male screw portions 5b and 6b formed on the other end sides of the first and second bolts 5 and 6, It consists of 2nd internal thread parts 13b and 14b which pinch | interpose the 2nd handle | pattern part 3a with the other end of the cylinder parts 11 and 12. FIG. The first and second female thread portions 13a, 13b, 14a, and 14b are called wing nuts, and can be tightened or loosened by hand without using a tool, so that workability on site is good.

  The assembly of the jointing and wiping tool 1 will be briefly described.

  Before assembling, the width L (see FIG. 3) between the first brush 2 and the second brush 3 is set between the joints 9a extending in parallel on the surface of the panel 9 as shown in FIG. Therefore, in consideration of the thicknesses of the first and second handle portions 2a and 3a, the cylindrical portions 11 and 12 having the necessary length are prepared.

  First, the bolts 5 and 6 are inserted into the tube portions 11 and 12, and the male screw portions 5a, 5b, 6a and 6b of the bolts 5 and 6 are exposed from both ends of the tube portions 11 and 12. In this state, the male screw portions 5a, 5b, 6a, 6b are inserted into the hole portions 7a, 7b, 8a, 8b of the first and second brushes 2, 3, respectively. At this time, the washers 16 and 17 are interposed between the end portions of the cylindrical portions 11 and 12 and the first and second handle portions 2a and 3a.

  Thereafter, the male screw portions 5a, 5b, 6a, 6b of the bolts 5, 6 projecting outward from the first and second handle portions 2a, 3a are connected to the female screw portions 13a, 13b, 14a via washers 18, 19. , 14b. Then, the female screw portions 13a, 13b, 14a, 14b are tightened to complete the assembly of the jointing and wiping tool 1.

  As shown in FIG. 4, the jointing and wiping tool 1 assembled in this way is put on the joints 9 a of the panel 9 by placing fingers on the cylindrical portions 11 and 12 of the first and second rod-like portions 10 and 20. The joint 9a is squeezed while moving in the direction of the arrow along the line. Thus, by using the two rod-like portions 10 and 20 extending in parallel between the first handle portion 2a and the second handle portion 3a, the two rod-like portions 10 and 20 are fingered. The jointing and wiping tool 1 can be firmly held, and the bristles 2b of the first brush 2 and the bristles 3b of the second brush 3 are adjacent to each other. Even in the state where the joint is pressed against the joint 9a at the same time, it is easy to move the arm in the traveling direction of the joint-wiping tool 1 (see the arrow in FIG. 4). As a result, the work load can be reduced and the work efficiency can be improved.

  In the ironing operation, the hair ends of the bristles 2b and 3b of the first and second brushes 2 and 3 are likely to be worn, and therefore it is necessary to replace them with new brushes. The first and second brushes 2 and 3 can be replaced only by removing the female screw portions 13a, 13b, 14a, and 14b from the fifth and sixth members.

  Furthermore, since the cylindrical portions 11 and 12 are employed, the handle portions 2a and 3a of the first and second brushes 2 and 3 can be brought into contact with both ends of the cylindrical portions 11 and 12, respectively. The parallelism between the brush 2 and the second brush 3 can be easily obtained. In addition, since the width L between the first brush 2 and the second brush 3 can be reliably determined by the length of the cylindrical portions 11 and 12, the length corresponding to the pitch P between the joints 9a. The width L between the first brush 2 and the second brush 3 can be easily changed simply by preparing the cylindrical portions 11 and 12. Further, it is only necessary to use two female screw portions 13a and 13b for one rod-shaped portion 10 and two female screw portions 14a and 14b for one rod-shaped portion 20, and assembling work. Good properties.

  The joint wiping tool 1 having such a configuration moves along the joint 9a in a state where the bristles 2b of the first brush 2 and the bristles 3b of the second brush 3 are simultaneously pressed against the adjacent joints 9a. It becomes possible to use it. As a result of enabling such ironing work, during the ironing work, the handle 2a of one brush 2 is moved in the direction of movement of the brushes 2 and 3 by the struts of the hairs 2b and 3b. The side handle 3a of the third handle 3a is prevented from falling down, and the ironing operation becomes very easy. Therefore, the efficiency of the ironing operation can be improved, and at the same time, unpainted and insufficiently painted are less likely to occur.

  In addition, since the ironing work of the joints 9a extending in parallel adjacent to each other can be performed at the same time, the working time can be shortened. In particular, in the case of ALC panel 9 coating, it is generally performed in three steps: undercoating, intermediate coating, and topcoating, but depending on the paint material and construction method, ironing is also performed in the case of intermediate coating. May be desirable. In such a case, the ironing work is increased, and therefore the use of the jointing and wiping tool 1 that can use the two brushes 2 and 3 at the same time is particularly effective.
