DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure such as an entrance porch, a porch or a terrace of a house.

[0002]

2. Description of the Related Art In a residential building, a porch may be formed at an entrance or a self-service entrance, or a terrace may be formed at a site facing a garden. Since such a porch or terrace is set at a position where the top level is higher than the ground level,
It is common to construct by performing tile work while adjusting the level of the poured slab concrete.

Here, the structure and construction procedure of a general porch or terrace will be described with reference to FIG. First, a concrete table 51 (soil concrete) is made at a target position. Next, while adjusting the passage and level using a kneading mortar with the water thread provided at the end of the base 51 as a reference, block-shaped step stones 52 and curbs 53 in which tiles are previously driven are laid. After that, back mortar 54 between table 51 and curb 53
And the two are joined.

[0004] Next, a base mortar 55 is formed on a table 51 surrounded by a curb 53, and a flat plate 56 on which a tile constituting a floor portion is previously driven is laid thereon. Thereafter, jointing is performed on the joint portion of the flat plate 56, and the remaining jointing material is wiped off, thereby completing the porch and terrace construction.

[0005]

In the above conventional method,
The work of laying while adjusting the level and passing through a stone, a curb and a flat plate requires a high level of skill, and there is a problem that the finished state depends on the skill of the installer. That is, depending on the skill of the installer, a step (vertical deviation) at the joint portion of each member due to a level adjustment defect,
There is a problem that misalignment (horizontal misalignment, tile joints become inconsistent) due to inadequate street adjustment is likely to occur.

[0006] Further, the step stone and the curb are only placed on the ground mortar 57 struck on the ground around the earth concrete, and the two are not substantially connected. For this reason, when a person gets on and off the vehicle, there is a problem that a portion of the step stone, in particular, sinks, and a crack is easily formed in a joint between the step stone and the curb.

An object of the present invention is to provide a porch or terrace structure which is not affected by the skill of a builder and does not crack over time.

[0008]

According to the present invention, there is provided a porch or terrace having a floor and a step extending from an edge of the floor. In this case, the floor is supported by a steel or precast concrete foundation beam, and the back side of the step is supported by a support fitting connected to the foundation beam.

In the structure of the porch or terrace (hereinafter, typically referred to as a "porch"), the floor is supported by a foundation beam, and the steps are supported by a support fitting connected to the foundation beam. The level of the foundation beam is adjusted before and after connecting the support bracket or supporting the floor, and when attaching the floor to the foundation beam and attaching the step to the support bracket coupled to the foundation beam, There is no need to adjust the levels and streets of these components.

Therefore, a uniform and stable pouch can be constructed without being affected by the skill of the installer. In particular, because the step is supported by the support bracket,
Even when a person gets on and off the vehicle, no unequal subsidence occurs on the floor, and no crack occurs between the floor and the steps.

In the above pouch structure, it is preferable that the support fitting has a support portion for supporting a concrete formwork, and that the support fitting is buried and the back side of the step is filled with concrete. With this configuration, the step portion is supported in contact with the entire surface on the back side of the concrete, so that extremely high stability can be exhibited.

Preferably, the floor is formed of a precast concrete plate, and furthermore, the step is formed of a precast concrete plate. By making the floor part and / or the step part made of precast concrete in this way, there is no step or misalignment.

Next, the structure of the pouch according to the second embodiment will be described with reference to FIGS. In the figure, the first
The same portions and portions having the same functions as in the embodiment are denoted by the same reference numerals, and description thereof is omitted.

The structure of the porch according to the present embodiment is such that a formwork 7a is attached to a support fitting 3 fixed to a web 2c of a foundation beam 2, and the base form 7 is filled in the formwork 7a to form a support fitting. 3 is embedded in a base concrete 7.

First, the mounting structure of the beam 1 and the foundation beam 2 of the main body will be described. The beam 1 of the main body is connected to a steel pole 14 attached to a precast concrete base plate 13 whose ends have been adjusted in advance. By connecting to the steel pole 9 attached to the base plate 15 made of precast concrete, the top level and the street of each of the beams 1 and 2 are set.

The base plates 13 and 15 are arranged at the positions where the beams 1 and 2 intersect according to a pre-designed base plan, and the level and the street are guaranteed. As such a construction method, there are already two technologies developed and filed by the present applicant.

For example, in the technique of Japanese Patent Application No. Hei 7-1089, after the ground work is performed at the installation position of the base plate, a self-leveling material is cast to assure a horizontal surface, and then the hardened self-leveling material is removed. A base plate is placed on the upper surface, a steel pole is attached, the street is adjusted while moving on the self-leveling material, and a liner is interposed between the base plate and the steel pole as necessary. By adjusting the level of the upper flange of the pole, it is possible to guarantee the level of the upper flange of the steel pole.

In the technique disclosed in Japanese Patent Application No. 8-168880, a recess is provided at a position where a base plate is to be installed, and a pile is driven into the recess to ensure the level by a method such as water filling, and the fluidity is provided in the recess. It is possible to fill a plate having a hole penetrating in the thickness direction from above the sand, and to guarantee the level of the plate when the plate comes into contact with the pile.
Therefore, it is possible to guarantee the level of the base plate by placing the base plate on the plate material, and it is also possible to guarantee the level of the steel poles 14, 9 attached to the base plate. .

Therefore, any of the above techniques may be employed for adjusting the level and the street by installing the base plates 13 and 15 at predetermined positions. In the present embodiment, the latter technique is employed. The base plates 13 and 15 are mounted on independent level plates 16 respectively, and the steel poles 1 attached to the base plates 13 and 15 are provided.
4 and 9 are guaranteed at a preset level and are also guaranteed.

When the beam 1 of the main body is connected to the steel pole 14 of which the level and the street are guaranteed as described above, and the foundation beam 2 is connected to the steel pole 9, Two levels and streets are also guaranteed. Therefore, when connecting the beams 1 and 2 to the steel poles 14 and 9,
The upper flanges 1a and 2a may be aligned with the upper flanges of the respective steel poles 14 and 9 at the same level without moving the upper and lower beams 14 and 9, thereby facilitating the connection of the beams 1 and 2. It is.

On the outer surface of the leg 3c of the support fitting 3, a pair of hook-shaped locking portions 3d for attaching the mold 7a is provided.
Are formed. Further, a projection 7b that engages with the locking portion 3d is formed on the mold frame 7a. Then, after attaching the supporting metal members 3 to the web 2c of the foundation beam 2 at a predetermined pitch, the outer periphery of the base concrete 7 is defined by engaging the projections 7b of the formwork 7a with the locking portions 3d of the supporting metal members 3. I do.

The upper end of the mold 7a attached to the support fitting 3 is formed so as to be equal to the mounting piece 3b of the fitting 3. In this embodiment, the base concrete 7 is filled up to the same height as the mounting piece 3b of the support fitting 3. For this reason, the base member 6 a of the step portion 6 is substantially supported by the base concrete 7. Therefore,
It is possible to make the mounting interval of the support fitting 3 to the foundation beam 2 wider than the interval in the above-described embodiment.

After disposing the formwork 7a as described above, the space defined by the formwork 7a is filled with concrete, and the base concrete 7 is formed. After the base concrete 7 has hardened, the base member 6a of the step portion 6 is attached to the support fitting 3 and the edge members 4 and the base members 4a, 5 of the flat member 5 are attached to the foundation beam 2 as in the above-described embodiment.
a, and a porch is formed by attaching tile sheets 4b to 6b to the surfaces of the base members 4a to 6a.

In the above embodiment, the top level of the steel poles 14, 9 is guaranteed with high accuracy. For this reason,
The level of the foundation beam 2 connected to the steel poles 14, 9 is also guaranteed, and the base members 4a, 4b,
The floor level can be set only by placing the base member 5a of the flat member 5. That is, no special level adjustment is required. Therefore, since the adjacent members 4 and 5 are at the same level, the step (vertical deviation)
Is not formed. Further, the base members 4a, 5a
Even if the tile sheets 4b and 5b are adhered on site or at the factory stage, no step is formed.

Further, since bolt holes are previously formed in the upper flange 2a of the foundation beam 2 in which the horizontal position accuracy is ensured, the edge members 4 constituting the floor portion correspond to the bolt holes.
The horizontal position of each of the members 4 and 5 is set by placing the flat member 5 thereon. Therefore, it is not necessary to adjust the street in particular, and the base member 4 of each of the members 4 and 5 is not required.
There is no misalignment (horizontal misalignment) between a and 5a, and joints do not misalign even when tiles are attached at the factory stage.

Since the support 3 is attached to the foundation beam 2 whose level accuracy and horizontal position accuracy are guaranteed, the level of the mounting piece 3b is also ensured. Therefore, the level and the horizontal position are set by mounting the base member 6a of the step portion 6 on the mounting piece 3b, and no special adjustment is required. Therefore, there is no step (vertical displacement) or inclination between the base members 6a of the adjacent step portions 6, and
Even if a tile sheet is stuck on the spot or stuck at the factory stage, there is no step or misalignment.

FIG. 8 is a view for explaining the structure of the step portion 6 when the height of the porch from the ground to the floor is high. As shown in the figure, the support member 3 has mounting pieces 3b corresponding to the number of steps required for the step portion 6, and the mounting pieces 3b are connected by legs 3c. Further, all the mounting pieces 3b and a part of the leg portions 3c are connected to the mounting pieces 3a and reinforced by the reinforcing member 17 fixed by welding or the like, so that the step portion 6 is stably mounted on each mounting piece 3b. It is possible to fix it in a state where it is set.

In each of the above embodiments, the case where the foundation beam 2 is made of steel H-section steel has been described. However, in the structure of the porch of the present invention, the foundation beam 2 does not necessarily need to be made of steel. It may be made of precast concrete. As described above, when a beam made of precast concrete is used as the foundation beam 2, since the beam is produced in a factory, it is possible to guarantee high dimensional accuracy. It is possible to ensure end-level accuracy.

When a precast concrete beam is used as the foundation beam 2, a plurality of nuts are insert-molded on the side surface of the beam at a predetermined pitch in advance, and the supporting bracket 3 is attached to the nut. Is preferred. If the nut is not insert-molded, it is preferable to insert-mold a steel plate and attach the support fitting 3 using a tapping screw.

[0047]

As described in detail above, in the porch or terrace structure according to the present invention, a foundation beam is provided and a support bracket is attached to the foundation beam, so that the floor is supported by the foundation beam and the step is supported. By supporting with metal fittings, it is possible to eliminate the need for level and street adjustment of the members constituting the floor and the steps. For this reason, a porch or terrace having stable accuracy can be configured without being affected by a difference in skill, and a construction period can be shortened and construction costs can be reduced.

Since the step portion is stably supported by the support metal attached to the foundation beam, only the step portion does not sink below the floor over time. For this reason, cracks do not occur between the steps and the edges forming the floor.

When the supporting bracket is buried in the base concrete, the step portion can be substantially supported by the base concrete, and the number of mounting the supporting bracket to the foundation beam can be reduced. The stability of the part can be further improved.

When the floor portion and the step portion are formed of a precast concrete plate, there is no step or stagger between the adjacent floor portion and the step portion.
