JPH0715939U - Wooden formwork for the relief of concrete - Google Patents

Abstract

(57) [Summary] [Purpose] To provide a wooden formwork for concrete relief that beautifully finishes the relief of concrete walls on the side of buildings and roads, does not require peeling work after formwork removal, and can be used repeatedly. That is. [Construction] A concrete characterized in that an adhesive 2 is applied to the superposed surfaces of a plurality of plate materials 1 to form a laminated plate 3 by press working, and an arbitrary tapering pattern 4 tapering outward is engraved. It is a wooden formwork for relief of.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a relief formed on a slope of a building or concrete beside a road.

[0002]

[Prior art]

 Conventionally, styrofoam and urethane rubber have been used as a mold for relief in order to form a relief on the wall of a building or concrete on the side of a road.

[0003]

[Problems to be solved by the device]

 However, in a mold using styrofoam, styrofoam that has not been peeled off adheres to the entire surface of the relief of the formed concrete, and a great deal of labor and chemicals such as thinner must be used to remove it. There wasn't. Also, with a mold made of urethane rubber, although the concrete formed can be easily peeled off from the entire relief surface, it is not possible to use it repeatedly after repeated breakage of the urethane rubber mold. There was a problem that it was not suitable and lacked in durability. In addition, when using styrofoam or urethane rubber, the original wooden mold and mold were required, so a great deal of labor, labor cost, and manufacturing cost were required to form the relief. Furthermore, there is a risk of destroying the natural environment with agents such as thinner.

[0004]

[Means for Solving the Problems]

 In view of the above problems, the present invention provides the following formwork. That is, the adhesive 2 is applied to the superposed surfaces of a plurality of plate materials 1 and is formed into a laminated plate 3 by pressing, and an arbitrary taper pattern 4 having an outward taper is engraved on the concrete. It is a wooden formwork for relief.

[0005]

[Action]

 In order to use the wooden formwork for concrete relief according to the present invention, a foundation wall and an optional unevenness pattern 4 are provided on a building or a roadside slope where a concrete relief is to be formed. If concrete is poured between the wooden formwork and the concrete is dried and then peeled off by removing the wooden formwork, the desired beautiful concrete relief 6 can be obtained on the slopes of buildings and roadsides. It is what is formed.

[0006]

【Example】

 In the figure, reference numeral 1 denotes a plate material having a water-based vinyl urethane adhesive 2 applied to the superposed surfaces thereof, which is pressed by a press or the like to form a laminated plate 3. Reference numeral 4 in the figure is an arbitrary uneven pattern carved and carved on the surface of the laminated plate 3 by an NC router or the like, and is directed outward in order to smoothly separate from the relief 6 formed on the concrete wall surface 5. Taper is attached. Incidentally, even if a solid plate material is used in place of the laminated plate 3, it is possible to obtain a wooden form which can similarly form a desired relief 6 of concrete.

[0007]

[Effect of device]

 Since the present invention is constructed as described above, it has the following excellent features. That is, since the formwork can be peeled off smoothly from the entire surface of the formed concrete relief, the concrete relief can be finished beautifully without any special finishing work, and the formwork collapses and the details collapse. There is no need to use it repeatedly, and it is economical because it uses an inexpensive laminated plate instead of an expensive flat plate material. Since it is possible to directly use a wooden plate engraved with an arbitrary uneven pattern as a formwork, it is possible to save useless labor and to complete the production cost at low cost. Furthermore, since thinners and other chemicals used for the relief surface removal work are unnecessary, it is very useful for protecting the natural environment.
