Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a flower box attached to a required opening such as a window of a building.

[0002]

2. Description of the Related Art A so-called flower box is used for the purpose of making it possible to plant various pots by using the openings on the second floor and above of the building, prevent people from falling, and enhance the design effect of the building. , Various designs are offered. Further, in recent years, it has been increasingly used as a storage space for articles, for example, for storing an outdoor unit of an air conditioner device.

A relatively large number of such flower boxes made of concrete, which are excellent in terms of material quality, are also provided.

[0004]

A concrete flower box conventionally provided in a so-called industrial production house is provided as a separate member from the building body, for example, by attaching a steel frame framework to the building frame, and the A precast concrete panel (PC panel) that forms each of the front wall, side wall, bottom wall, etc. is attached to the corresponding surface and the gap between the panels is closed with a caulking agent, etc. Target.

This is because if the required contour of the flower box is molded integrally with concrete, the weight becomes considerable.
One of the reasons is that it causes a problem in safety in construction work.

However, in the field assembly work using the PC panel, in addition to the problem of quality variation as compared with the integral molding, it is necessary to solve such problems that the proportion of relatively small articles is time-consuming in terms of work. Met.

The present invention is intended to be provided in view of the above conventional problems. INDUSTRIAL APPLICABILITY The present invention utilizes the fact that the lightweight cellular concrete obtained by so-called autoclave treatment is smaller than the specific gravity of the PC panel by a factor of a few or more, so that a flower box can be formed by integral molding and mass production can be performed with uniform quality. The purpose is to obtain a flower box that is easy to construct.

[0008]

In order to achieve the above-mentioned object, the flower box according to the present invention comprises a reinforcing bar material in which a nut for mounting to a building frame is arranged so as to open on the inner surface of the wall. As the core material, at least the upper surface and the back surface are opened, and the front wall and the side wall with an appropriate three-dimensional pattern on the outer surface, the calcareous raw material and the siliceous raw material as the main raw materials, to which water, an admixture, etc. are added, and further in advance. The concrete slurry is formed by pouring a concrete slurry in which bubbles are generated into a mold, and is integrally molded with lightweight cellular concrete obtained by an autoclave treatment after demolding.

Such a flower box has a substantially L-shaped form panel in a side view in which a mold member having an appropriate three-dimensional shape is attached to the surface to form an outer surface of the front wall and an outer surface of the bottom surface of the flower box. A mold member with an appropriate three-dimensional pattern on the surface is pasted to form a side wall outer surface of the flower box and a form panel forming the outer surface of the flower box. A formwork panel formed by forming an appropriate convex portion to form an open rear inner surface of the flower box and holding the reinforcing bar at an appropriate interval is used for the outer surface of the side wall on the opening face of the assembled formwork. A hollow part in which the reinforcing bar is located is formed in the middle of the inside by assembling with the mold panel leaving an opening for the side wall thickness to be obtained, and then the hollow part is lightened from the opening. Aerated concrete slurry And pouring, and subsequently demolded be produced by performing the autoclave treatment.

In this case, the nut provided on the reinforcing bar so as to open inside the front wall and inside the side wall of the flower box is separated from the mold surface when the reinforcing bar is set in the hollow portion of the mold. It will be used for screwing the fixing bolt for positioning and holding, and also for screwing the bracket mounting bolt when mounting the flower box to the building body.

[0011]

In the flower box, the front wall and the side wall are integrally formed of lightweight cellular concrete having a very small specific gravity, so that the work of attaching to the building frame can be performed safely and easily. Further, since the flower box main body is completed in advance, quality such as shape and size is uniform, and labor saving at the construction site can be achieved, which contributes to quick construction.

Fig. 3 is a perspective view showing the structure of the reinforcing bar to be installed, Fig. 3 is a perspective view of a form showing a state in which a lightweight cellular concrete slurry is placed, Fig. 4 is a sectional view taken along the line XX in Fig. 3, and Fig. 5 is a diagram. 4 is a cross-sectional view taken along the line Y-Y in FIG. 4, FIG. 6 is an external perspective view of the flower box, and FIG.

In FIGS. 1 and 3 to 5, the mold frame 1 forms a substantially rectangular parallelepiped when the assembly is completed, so that the mold frame panel 2 (2) is formed.
a, 2b), 3, 4, and 5.

The formwork panels 2a and 2b form the outer surface of the front wall 21 and the outer surface of the bottom surface 24 of the flower box 20 (see FIG. 6) to be obtained. In this embodiment, they are separated during normal use. Since it is not necessary, it can be separated by tightening bolts, but it is practically integrated. This formwork panel 2 has a substantially L-shape when viewed from the side, and the length (left and right in the drawing of FIG. 5) corresponds to the length of the flower box 20, and the width of one formwork panel 2a (in the drawing of FIG. 4). The horizontal direction) corresponds to the height of the flower box 20, and the width of the other mold panel 2b (vertical direction in the drawing of FIG. 4) corresponds to the depth of the flower box 20.

A mold member 2c having an appropriate three-dimensional pattern (generally brick-like in the illustrated example) is attached to the inner side surfaces of the mold frame panels 2a and 2b. The mold member 2c has a moldability,
It is manufactured by using a material satisfying necessary conditions such as durability and hardness, for example, a urethane material.

The formwork panels 3 and 3 are the flower box 2
Forming the outer surface of the side wall 22 of 0, the formwork panel 2
It is designed to be separably assembled on both sides with bolts. This formwork panel 3 has dimensions corresponding to the above height and depth of the flower box 20, and on the inner side surface thereof,
The same mold member 3a as the mold frame panel 2 is attached.

The formwork panel 4 forms the outer surface of the upper surface 23 of the flower box 20. The formwork panel 2a,
It is designed to be separably attached to one side of No. 3 with a bolt or the like. The formwork panel 4 has dimensions corresponding to the length and depth of the flower box 20, and the inner side surface of the formwork panel 4 is the same as that of the panel material on which the mold member as described above is not attached. This is because a plank (not shown) is planned to be attached to the upper surface 23 of the flower box 20, and when the desired pattern is to be applied without attaching the plank, the other formwork described above is used. A mold member may be attached similarly to the panel.

The formwork panel 5 forms an inner rear surface 25 of the flower box 20. For ease of use, one side of the formwork panel 2b is rotatably attached by a hinge 6 to the formwork panel 2b. There is. Then, a locking piece 7 for locking the formwork panel 4 when required is projected on the other side.
In the case of the illustrated example, a bar member 7a is provided on the back surface for convenience of opening and closing a mold panel, which will be described later, and the hinge 6 portion and the locking piece 7 portion are integrated.

The panel length is the flower box 20.
The thickness of both side walls 22, 22 is shortened. That is, the lightweight cellular concrete slurry LC can be poured from the side wall corresponding portion opened at the time of assembly. Therefore, the assembled formwork 1 is arranged in a posture with the formwork panel 2a as the bottom surface.

This formwork panel 5 is the other formwork panel 2,
After assembling 3, 4, the so-called lid is assembled on the opening surface. Then, the front wall 21 of the flower box 20 is fixed between the formwork panels 2a, 3 and 3 by fixing with an appropriate clamp tool.
A hollow portion 8 corresponding to the thickness of the side wall 22 is formed. In the formwork panel 5, if the hinge 6 can be inserted and removed freely,
After assembling another form panel, the hinge 6 portion can be shifted and placed on the opening surface, and then the hinge pin can be slid so as to be engaged and assembled.

A mold member 5a made of the same material as other mold panels is attached to the inner surface of the mold panel 5, and a required convex portion is formed so as to form the back open inner surface 25 of the flower box 20 as a space. 5b is formed. Since the inner surface 25 of the flower box 20 is generally formed flat without any particular pattern, the mold member 5a is not always necessary, and the main body of the mold frame panel 5 is formed into the convex shape. It is also possible to form the part 5b by molding.

Further, the formwork panel 5 has insertion holes (not shown) for fixing bolts (not shown) which penetrate the inside and outside of the panel surface to support the bar arrangement material 10 shown in FIG. 2 when necessary. )
Is provided at a position where it is screwed into a nut of the reinforcing bar 10 described later.

FIG. 2 shows the reinforcing bar 10 arranged inside the flower box 20. The bar arrangement material 10 is formed by appropriately combining the angle material 10a and the connecting material 10b into a shape including the front wall 21 and the side wall 22 of the flower box 20, and functions as a reinforcing core material of the flower box 20. Therefore, in terms of configuration, so-called mesh streaks may be used in addition to the above angle members, and an appropriate configuration may be adopted depending on design strength and the like.

On the inner surface of the bar arrangement member 10 corresponding to both sides of the front wall 21 of the flower box 20 and the inner surface of the side wall 22,
Nuts 11, 11, 12, and 12 are provided on each. The nut 11 is oriented from the front wall to the outside of the back,
The nuts 12 are arranged so as to face each other. In the example shown in the figure, two of them are arranged in each of the above four places. Two nuts 13 and 13 are arranged on the upper surface side of the bar arrangement member 10 at positions corresponding to both corners of the flower box 20 so as to face upward.

The nuts 11, 12 and 13 are set to heights such that they open on the wall surface when the flower box 20 is molded. In other words, the concrete covering thickness of the reinforcing bar material 10 and the heights of the nuts 11, 12, and 13 are set to be substantially the same.

The nuts 11 and 12 are used not only for screwing the bolts for fixing the bracket at the time of mounting on the building frame, which will be described later, but also for screwing the fixing bolts for the form panel 5 described above. Therefore, they are arranged so as to be aligned with the positions of the fixing bolt insertion mounting holes. Further, the nut 13 is used not only as a nut for attaching an additional member such as a cover for makeup, but also as a nut for screwing a hook member of a lifting device such as a crane in a work of attaching to a building frame described later. I am trying to do it.

In the flower box 20 shown in FIG. 6, the reinforcing material 10 is held on the formwork panel 5 via fixing bolts.
The lightweight cellular concrete slurry LC is cast into the formwork 1 constructed by assembling the formwork panels 2, 3, 4, 5 and arranging the reinforcing material 10 in the hollow portion 8 formed inside, and then removing it. It is obtained by molding and further autoclaving.

In demolding, first, the mold frame panel 4 is separated, and the mold frame panel 5 is rotated around the hinge 6 as a shaft to separate it.
Next, the side wall mold panels 3 and 3 are separated, and the mold panel 4 side is inverted so that the mold panel 3 is separated from the molded flower box. If a mold release agent is applied to the surface of each mold panel, the above separation can be performed more smoothly.

In the above lightweight cellular concrete, the calcareous raw material and the siliceous raw material are used as main raw materials, water, an admixture, etc. are added thereto, and bubbles are also generated in advance by a surfactant or the like, and then the concrete is cast into a mold. Then, it is primarily cured and molded, and is obtained by stabilizing physical properties and the like by steam curing (autoclave) under high temperature and high pressure, and its specific composition and the like are known.

Some lightweight cellular concrete can be obtained by foaming in a mold using metal powder as a foaming agent. However, in a three-dimensional object such as the flower box 20 of the present invention, a deep part is formed due to pressure. Therefore, it is not possible to use because there are quality problems such as the generation of required foam being disturbed and the density of the foam being varied.

The flower box 20 obtained by the manufacturing method of the present invention is attached to the skeleton A of the building B by means of a bracket 30 as shown in FIG.

The skeleton A is a pillar or a beam of the building B, or an arm member provided on the pillar, the beam or the like (the example of the figure shows the tip end surface of the arm member having a bolt hole). Bracket 30
Is pre-attached to the nuts 11 and 12 opening inside the front wall 21 and the side wall 22 of the flower box 20 with attachment bolts (not shown). The flower box 20 is hoisted by a hoisting device such as a crane using the nut 13 opened on the upper surface 23, and the bracket 30 is brought into contact with the skeleton A. Next, the bracket 30 and the skeleton A are fixed with bolts or welded if necessary.
Then, from the upper surface 23 side of the flower box 20, the shelf plate 31 is attached to the inner space portion, and if necessary, the bottom plate 32 is attached. The shelf plate and the bottom plate may be fixed to the upper surface and the lower surface of the bracket 30 with appropriate bolts using the bracket 30.
