Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention is easy to construct,
Moreover, the present invention relates to providing a gate having uniform appearance and good appearance.

[0002]

2. Description of the Related Art Gates forming entrances and exits of various buildings and entrances and exits of various boundary means are, for example, those formed by applying a surface finish of lath mesh mortar to a steel structure, or those made of cast reinforced concrete. Some were constructed and others were constructed by applying a surface finish to ceramic structures with ceramic siding.

[0003]

However, in the case of a gate constructed by applying a lath net finish to the above-mentioned steel frame structure, the gate can be formed in a short construction period, but it is satisfactory. There is a problem in that the configuration of the gate with the obtained surface makeup requires a large amount of material and manpower, and the finishing material on the gate surface is vulnerable to vibration, easily cracked outside, and difficult to waterproof. There was a problem that rust generated inside oozed out and spoiled the appearance of the surface finish.

In the above-mentioned gate made of cast-in reinforced concrete, a formwork such as a temporary formwork, a shoring process, a concrete pouring process, a curing process of a cast concrete, a demolding process, etc. However, there are disadvantages such as requiring a lot of construction labor such as surface decoration treatment for the cast concrete surface to be formed, a lot of construction materials, and a long construction period for curing and the like.

Further, in the above-mentioned method using a ceramic siding material as a surface finishing material for a steel structure, it is difficult to divert a ceramic siding material used for a house to the structure of the gate. Unless a special siding material is prepared, there is a problem that it is difficult to achieve harmony with the appearance of the house, and there has been a problem that the gate constituted by using such a special siding material is expensive.

[0006] In order to solve such a problem in the conventional gate, the present invention uses a precast concrete side frame material and a precast concrete upper frame material that are formed on a previously cast and prepared foundation. It is an object of the present invention to provide a gate which is configured to have uniform quality and good appearance in a short period of time without requiring special techniques.

[0007]

According to a first aspect of the present invention, there is provided an invention having a receiving portion for receiving an anchor bolt provided on a foundation, and an anchor bolt received by the receiving portion. At least a pair of precast concrete side frame members fixed to the foundation, and both sides of the precast concrete side frame material being bridged between upper sides of the precast concrete side frame members provided on the foundation. And a precast concrete upper frame material to which the gate is fixed.

In the gate configured as described above,
A precast concrete side frame is fastened to the foundation with anchor bolts provided on the foundation, and the precast concrete side frame is fixed to the foundation so as to pass between the upper sides of the precast concrete side frame. By fixing the frame material to the precast concrete side frame material, a concrete gate having a uniform strength and a uniform appearance can be formed.

Further, in the gate having such a configuration, the surface of the configured gate is a concrete plate surface,
This concrete plate surface can be used as a gate surface, and can also be used as an underground for decorative finishing.

Next, according to a second aspect of the present invention, in order to achieve the above-mentioned object, in the first aspect of the present invention, the pre-cast concrete side frame members are attached to the foundation so that their plate faces face each other. Are provided as a pair of precast concrete side plates, and the precast concrete upper frame material is bridged between upper facing sides of both side edges of the precast concrete side plate, and both sides of the precast concrete side plate are provided. A pair of precast concrete beam plates whose parts are fastened, and attached to the precast concrete beam plate and the upper end surface of the precast concrete side plate to be fastened to the precast concrete beam plate and the precast concrete side plate. Precast concrete There as a gate, characterized in that the bets upper plate.

In the gate configured as described above,
In addition to the above features, it is possible to configure a gate having a depth width and a storage space with a lower opening on the upper side between the precast concrete beam plate and the precast concrete upper plate.

According to a third aspect of the present invention, in order to achieve the above object, in the second aspect of the present invention, the precast concrete side plate comprises a rectangular plate-shaped main body, A receiving plate portion provided between the lower end and the upper side of the side edge so as to protrude from the plate surface along both side edges on one plate surface side of the main body portion; The gate is characterized in that the receiving plate portion is provided as a mounting surface for the precast concrete beam plate.

In the gate constructed as described above,
In addition to the above features, the precast concrete beam plate can be securely and easily assembled to the precast concrete side plate and fixed.

In the gate configured as described above, the receiving plates provided on the front and rear surfaces of the configured gate provide sufficient strength to the gate and have a good appearance. It is said.

A shutter 72 which is attached in a state and is drawn out of the shutter box 71 so as to be able to be taken in and out is configured so as to openably close an opening formed between the precast concrete side frame member 1 and the precast concrete upper frame member 2 in the gate A. . In the drawing, reference numeral 73 denotes a shutter drum of the shutter 72, and reference numeral 74 denotes a driving unit thereof.

The gate A according to the above configuration is easy to construct on site, and does not require any special technique for assembling the gate A. The gate A can be configured in a short time. In addition, the gate A is configured to have various characteristics such as desired strength characteristics and appearance characteristics, and is configured as the gate A that can easily perform a makeup process on the outer surface.

[0076]

The gate according to the present invention has a receiving portion for receiving an anchor bolt provided on a foundation, and at least one pair of precast concrete fixed to the foundation with the anchor bolt received in the receiving portion. A side frame member, and a precast concrete upper frame member which is bridged between upper sides of the precast concrete side frame member provided on the foundation and has both sides fixed to the precast concrete side frame member. In this configuration, the precast concrete side frame member is fixed on the foundation with the anchor bolts provided on the foundation, and the upper side of the precast concrete side frame member fixed to the foundation is fixed. Fasten the precast concrete upper frame material to the precast concrete side frame material so as to pass over By, it has the advantage of easily forming the gate of Concrete with a uniform appearance and having a uniform intensity.

Further, in the gate having such a configuration, the surface of the configured gate is a concrete plate surface,
The concrete plate surface can be used as a gate surface, and there is an advantage that the gate surface can be conveniently used as a lower ground surface for decorative finishing.
