Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates mainly to a formwork member for forming a decorative pattern on a wall surface of a concrete railing.

[0002]

2. Description of the Related Art When a decorative pattern such as a slit-shaped continuous pattern is provided on a concrete wall surface, for example, a wall surface of a concrete railing, the inner surface of a form body of the wall surface is generally processed. However, processing the formwork body is costly, and as a result, the construction cost tends to be high.

[0003] In some designs, it is difficult to process the frame body. For example, there are cases where the thickness is extremely thin or the width is narrow. In order to apply a decorative pattern, which is difficult to form on the mold body, to a wall surface, a mold member for forming a decorative pattern having a shape corresponding thereto is used.

A mold member for forming a decorative pattern is formed of a material such as PVC, for example, in the case of a slit-shaped decorative pattern, to have a sectional shape and length corresponding to the slit, and is fixed to the inner surface of the form body at a predetermined pitch. Being used.

[0005]

However, since the conventional frame member for forming a decorative pattern is formed of PVC, it is difficult to handle the narrow and thin case as described above. Fixing work becomes troublesome.

Further, when the nail is nailed during fixing to the formwork body, the head of the nail is exposed and the decorative pattern cannot be finished finely. Although it may be fixed to the mold body using a double-sided tape, it is easy to peel off and is not practical.

Further, materials cannot be used because they cannot be used repeatedly.

SUMMARY OF THE INVENTION In view of the above-mentioned problems of the prior art, an object of the present invention is to provide a concrete wall surface decorative pattern that can be easily fixed to a formwork body, has a good decorative pattern finish, and can be used repeatedly. An object of the present invention is to provide a forming frame member.

[0009]

SUMMARY OF THE INVENTION The present invention is characterized in that the following objects are provided in order to achieve the above object. That is, this form member is a form member for forming a decorative pattern which is detachably fixed to the inner surface of the form body of a concrete wall surface such as a concrete railing. A core is embedded inside the main body for forming the decorative pattern along the length direction thereof, and a mounting rod is fixed to the core so as to extend rearward of the main body. The mounting rod has a distal end protruding from a mounting hole provided in the form body to the outer surface of the form body, and is detachably fixed to the form body by a fixing member.

The main body is preferably formed of a hard urethane material. The core material is preferably a hard plate material extending along the length direction of the main body. Furthermore, the mounting rod is
A male screw is preferably formed on the outer periphery of the distal end portion, and a nut serving as a fixing member is screwed to the male screw to fix the present form member to the form body in a detachable manner. It is desirable that the mounting rods protrude from the rear surfaces of both ends of the main body, and are also provided at the intermediate portion in the longitudinal direction as necessary.

[0011]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below in detail based on illustrated embodiments. 1 to 3 are a plan view, a side view, and an enlarged perspective view of one end of a frame member for forming a decorative pattern according to an embodiment of the present invention.

This form member 1 is for forming a slit pattern which is long and thin in the vertical direction on the wall surface of the railing. The main body 2 has a substantially trapezoidal cross section, is long and thin in the vertical direction, and has a thick upper end. The lower end is formed to be thin. By the way, the main body is 20 mm in width and 430 mm in length in this embodiment,
The thickness is set to 10 mm at the upper end and 2 mm at the lower end. The main body 2 is formed of a hard urethane material, and a core material 3 is embedded therein along the length direction (FIG. 3).
reference). The core 3 is made of a thin metal plate.
For the main body 2 having the above dimensions, for example, a 0.5 mm thick plate material is used as the core material.

At both ends and substantially in the middle of the core member 3, a mounting rod 4 is provided so as to protrude rearward of the main body 2. These mounting rods 4 have their base ends welded to the back surface of the core member 3 and have external threads 4a formed on the outer periphery. Numeral 5 is a nut screwed onto the male screw 4a of the mounting rod 4 for detachably fixing the form member 1 to the form body 6 (see FIGS. 6 and 7).

The state of use of the mold member will be described. FIG.
When constructing a bridge railing 7 for a bridge shown in FIG. 1, usually, a base portion 7a including a pavement portion is formed on a road surface portion 8 using a predetermined formwork 9, and then the formwork is formed on the base portion 7a. 9 to form a railing wall 7b (see FIG. 6). The formwork 9 forming the railing wall portion 7b is a general formwork body 6 including a weir plate 6a, vertical and horizontal flaps (pipe material) 6b, 6c for holding the same from outside, a foam tie (registered trademark) 6d, and the like. Is provided.

The formwork member 1 according to the present invention comprises a railing wall 7b.
Is fixed in advance or on site to a formwork body 6 (the formwork body on the left side in FIG. 6) located on the road surface side. Specifically, the mounting rod 4 of the form member 1 is inserted into a through hole 10 (see FIG. 5) formed at a predetermined position of the dam plate 6a of the form body 6, that is, at a position where the slit pattern is formed. The tip of the mounting rod 4 protruding from the back surface of the weir plate 6a is tightened with the nut 5 (see FIG. 5). As a result, the form member 1 is fixed to the inner surface of the weir plate of the form body 6 at a predetermined pitch in an orderly and firm manner. At the time of the fixing work, the main body 2 of the form member 1 has a rigid core material 3 embedded therein, so that it is easier to handle than the conventional one.

The dam plate 6a to which the form member 1 is attached is mounted together with the other components of the form 9 in the same manner as in the prior art with reference to FIGS.
It is assembled as shown in. In both drawings, reference numeral 6e in the drawings is a separator. After that, concrete will be put into the formwork, and reinforcing bars will be installed inside if necessary.
After the concrete is solidified and dried, it is released and the railing wall 7b
A decorative pattern 11 having a concave slit shape is formed. Since the foreign matter such as a nail head does not appear on the outer surface of the main body of the formwork member 1, the concave pattern has a beautiful appearance.

By loosening the nut 5 on the outer surface of the weir plate, each mold member 1 is detached from the weir plate 6a. Therefore, the mold member 1 can be reused at different sites.

It is to be noted that, in the case of the railing on which the concave decorative pattern of the present invention is formed, for example, by arranging lighting devices at desired intervals on the upper surface of the railing, the landscape is improved due to the shadow at night.

The present invention can be similarly applied to a concrete wall surface other than the railing wall surface. In the above-described embodiment, the shape of the main body of the mold member is formed in an elongated strip shape. However, the present invention is not limited to the outer shape and the cross-sectional shape. The mounting rod is provided at an appropriate position so as not to cause a shift in the frame member in the frame body. Various other specific configurations can be adopted as long as the mounting rod fixing means is detachable.

[0020]

As described above, according to the present invention, since the core material is embedded in the main body of the form member for forming the decorative pattern along the length direction, the fixing operation to the form body is performed. Can be handled easily.

Further, according to the present invention, since the mounting rod protruding from the back of the main body is detachably mounted on the mold body via the fixing member, this kind of form member is attached to the form body. Not only can it be firmly fixed, it can be used repeatedly, and the decorative pattern can be finished well.
