Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a structure such as an entrance porch, a self-contained porch or a terrace of a house.
[0002]
[Prior art]
In residential construction, a porch may be formed at the entrance or the entrance, or a terrace may be formed at a part facing the garden. Since such a pouch or terrace is set at a position where the top level is higher than the ground level, it is generally constructed by performing tile work while adjusting the level of the placed concrete.
[0003]
Here, the structure and construction procedure of a general pouch or terrace will be described with reference to FIG. First, a concrete stand 51 (concrete concrete) is made at a target position. Next, the block-shaped step stones 52 and the curb stones 53 in which tiles are preliminarily placed are arranged while adjusting the level and the level using the kneaded mortar with the water thread provided at the end of the base 51 as a reference. Thereafter, the backfill mortar 54 is filled between the platform 51 and the curb 53 and joined together.
[0004]
Next, a base mortar 55 is formed on a table 51 surrounded by a curb 53, and a flat plate 56 into which tiles have been previously placed is placed. Thereafter, jointing is performed on the joint portion of the flat plate 56, and the remaining joint material is wiped off to complete the porch and the terrace work.
[0005]
[Problems to be solved by the invention]
In the above-mentioned conventional construction method, there is a problem that a high level of skill is required for the work of passing through steps, curbs, and flat plates while adjusting the level, and the finished state depends on the skill of the installer. That is, depending on the skill of the installer, the level difference (vertical deviation) in the joints of each member due to a level adjustment defect, or a misalignment due to a road adjustment defect (horizontal deviation, tile joints may not be aligned. ) Is likely to occur.
[0006]
Further, the stone and the curb are only placed on the ground mortar 57 struck on the ground around the soil concrete, and the two are not substantially connected. For this reason, when a person gets on and off, there is a problem that a part of the step stones sinks in particular, and a crack is easily formed at a joint between the step stones and the curbstone.
[0007]
An object of the present invention is to provide a pouch or terrace structure that does not depend on the skill of the installer and that does not crack over time.
[0008]
[Means for Solving the Problems]
In order to solve the above problems, the structure of a pouch or terrace according to the present invention is a structure of a pouch or terrace having a floor portion and a step portion extended from an edge of the floor portion, wherein the floor portion is made of steel. Alternatively, the back side of the stepped portion is supported by a support bracket that is supported by a foundation beam made of precast concrete and is coupled to the foundation beam and supports a concrete formwork, and the support bracket is embedded. The back side of the step part is filled with concrete.
[0009]
In the structure of the above porch or terrace (hereinafter referred to as “pouch”), the floor is supported by a foundation beam, and the step is supported by a support fitting coupled to the foundation beam. Before the base beam is joined to the support bracket or the floor portion is supported, both the level and the street are adjusted, and when the floor portion is attached to the foundation beam and the step portion is attached to the support fixture joined to the foundation beam, There is no need to adjust the level or street of these members.
[0010]
Furthermore, by supporting the concrete formwork by the support part provided on the support metal, and filling the back of the step part with the support metal, the back part of the step part is supported by the entire surface in contact with the concrete. Therefore, extremely high stability can be exhibited.
[0011]
For this reason, a uniform and stable pouch can be constituted without being influenced by the workman's skill. In particular, since the step portion is supported by the support bracket, even if a person gets on and off, the floor portion does not sink unevenly, and a crack does not occur between the floor portion and the step portion.
[0012]

The pouch is configured by allocating and fixing to the center 2a and fixing the stepped portion 6 extended from the edge to the support fitting 3.
[0025]
As each of the members 4 to 6, it is possible to use a mortar layer that has been preliminarily pasted with a tile and configured in a block shape. In this embodiment, the edge member 4, the flat member 5, and the step portion 6 are used. A base member 4a to 6a made of a precast concrete block having a shape and dimensions corresponding to each part, and a base member 4a having standard dimensions (for example, 300 mm × 300 mm, 600 mm × 600 mm, etc.) It is comprised by tile sheet | seat 4b-6b stuck on the surface of -6a.
[0026]
That is, the edge member 4 and the step part 6 are configured by attaching tile sheets 4b and 6b to the surface of the base members 4a and 6a made of precast concrete formed in an L shape, and the flat member 5 is formed in a plate shape. A tile sheet 5b is attached to the surface of a base member 5a made of precast concrete.
[0027]
The base members 4a and 5a constituting the floor portion are respectively formed with bolt holes 4c and 5c at the same pitch as the bolt holes 2d formed in the upper flange 2a of the base beam 2, and the base member constituting the step portion 6 is formed. Bolt holes 6c are formed in 6a at a pitch equal to the bolt holes 2d formed in the web 2c of the foundation beam 2.
[0028]
Since each of the base members 4a to 6a is manufactured at a factory stage, sufficiently high dimensional accuracy is ensured. Accordingly, when the base members 4a to 6a are attached to the base beam 2 and the support bracket 3, the level accuracy on these surfaces depends on the level accuracy of the base beam 2 and the dimensional accuracy of the base members 4a to 6a. Therefore, sufficient reliability can be obtained.
[0029]
Each of the tile sheets 4b to 6b is configured by bonding a plurality of tiles having predetermined dimensions to a sheet-like synthetic resin or rubber. The tile sheets 4b to 6b may be attached to the base members 4a to 6a at the factory stage or at the site stage. Furthermore, the tile may be directly driven into the base layer made of precast concrete at the factory stage without using the above-described sheet-like synthetic resin.
[0030]
In the present embodiment, the base member 6a of the step portion 6 is placed on the support fitting 3, the bolt 10a is screwed into the nut 11, and the member 6a is fastened to the support fitting 3, and the base member of the edge member 4 is also secured. 4a is placed on the upper flange 2a of the base beam 2 and fixed to the beam 2 with bolts 10a and nuts 10b, and one end of the base member 5a of the flat member 5 is connected to the web 1c of the beam 1 of the main body. It is possible to form the base of the pouch by placing it on the receiving angle 8 fixed to the base beam 2 and placing the other end on the foundation beam 2 and fixing it to the foundation beam 2 with bolts 10a and nuts 10b.
[0031]
As described above, the base members 4a to 6a are fixed to the base beam 2 and the support bracket 3, and then the tile sheets 4b to 6b are attached to the surfaces of the base members 4a to 6a, thereby completing the target pouch. Is possible.
[0032]
Next, a procedure for configuring the pouch according to the present embodiment will be described with reference to FIG. 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 base plate 13 made of a precast concrete whose end is adjusted in advance in both level and street, and the end of the foundation beam 2 is adjusted in advance in both level and street. By connecting to the steel pole 9 attached to the base plate 15 made of precast concrete, the top end levels and streets of the beams 1 and 2 are set.
[0033]
The base plates 13 and 15 are arranged at positions where the beams 1 and 2 cross each other according to a pre-designed foundation plan, and the level and street are guaranteed. As such a construction method, there are two techniques that have already been developed and filed by the applicant.
[0034]
For example, in the technology of Japanese Patent Application No. 7-1089, after applying ground work to the base plate installation position, a self-leveling material is placed to guarantee a horizontal surface, and then the foundation is placed on the upper surface of the cured self-leveling material. Place the plate and attach the steel pole, adjust the street while moving it on the self-leveling material, and if necessary, insert a liner between the base plate and the steel pole to It is possible to guarantee the level of the upper flange of the steel pole by adjusting the level of the flange.
[0035]
In the technique of 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 inserted into the recess to guarantee a level by a method such as water filling, and sand having good fluidity is provided in the recess. It is possible to bury a plate material having a hole penetrating in the thickness direction from above the sand and guarantee the level of the plate material when the plate material abuts against 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 and 9 attached to the base plate. .
[0036]
Accordingly, any of the above-described techniques may be employed when the base plates 13 and 15 are installed at predetermined positions and the level and street are adjusted. In this embodiment, since the latter technology is employed, the base plate 13 , 15 are mounted on independent level plates 16, and the steel poles 14, 9 attached to the base plates 13, 15 are guaranteed at a preset level and the street is also guaranteed.
[0037]
When the beam 1 of the main body is connected to the steel pole 14 whose level and street are guaranteed as described above, and the foundation beam 2 is connected to the steel pole 9, the level of these beams 1 and 2 is set. 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 are at the same level as the upper flanges of the steel poles 14 and 9 without moving the poles 14 and 9. Therefore, it is possible to easily connect the beams 1 and 2.
[0038]
The base metal 7 is fixed by fixing the support metal 3 to the web 2c of the foundation beam 2 and engaging the projection 7b of the mold 7a with the support 3d formed on the outer surface of the leg 3c of the support metal 3. The formwork 7a which prescribes | regulates the outer periphery of is attached.
[0039]
After the mold frame 7a is arranged as described above, the concrete defined in the space defined by the mold frame 7a is filled to form the base concrete 7. After the base concrete 7 is hardened, as described above, the base member 6a of the step portion 6 is attached to the support bracket 3, the edge member 4, and the base members 4a and 5a of the flat member 5 are attached to the foundation beam 2, A pouch is configured by attaching tile sheets 4b to 6b to the surfaces of the base members 4a to 6a.
[0040]
In the present embodiment, the top level of the steel poles 14 and 9 is guaranteed with high accuracy. For this reason, the level of the foundation beam 2 connected to the steel poles 14 and 9 is guaranteed, and the base member 4a of the edge member 4 and the base member 5a of the flat member 5 are simply placed, and the floor The level of the part can be set. That is, no special level adjustment is required. Accordingly, since the adjacent members 4 and 5 are at the same level, a step (vertical deviation) is not formed. Furthermore, even if the tile sheets 4b and 5b for the base members 4a and 5a are pasted in the field or at the factory stage, no step is formed.
[0041]
In addition, since the bolt holes are formed in the upper flange 2a in advance in the foundation beam 2 in which the horizontal position accuracy is ensured, the edge member 4 and the flat member 5 constituting the floor portion are mounted corresponding to the bolt holes. As a result, the horizontal positions of the members 4 and 5 are set. For this reason, it is not necessary to adjust the street specially, and the base members 4a and 5a of the members 4 and 5 are free from misunderstanding (horizontal misalignment), and even when tiles are pasted at the factory stage, Will not shift.
[0042]
Moreover, since the support metal fitting 3 is attached to the foundation beam 2 in which level accuracy and horizontal position accuracy are guaranteed, the level of the mounting piece 3b is also guaranteed. Therefore, the level and the horizontal position are set by placing the base member 6a of the step portion 6 on the placing piece 3b, and no special adjustment is required. For this reason, there is no step (vertical misalignment) or inclination between the base members 6a of the adjacent stepped portions 6, and even when a tile sheet is pasted on site or when pasting at the factory stage Even so, there will be no steps or mistakes.
[0043]
In the above embodiment, the case where the foundation beam 2 is made of steel H-shaped steel has been described. However, in the structure of the pouch of the present invention, the foundation beam 2 does not necessarily need to be made of steel, and is made of precast concrete. It may be. Thus, when a precast concrete beam is used as the foundation beam 2, it is possible to guarantee high dimensional accuracy because the beam is manufactured at the factory, and the top beam is the same as when using a steel beam. It is possible to ensure end-level accuracy.
[0044]
When a precast concrete beam is used as the foundation beam 2, it is preferable that a plurality of nuts are insert-molded in advance at a predetermined pitch on the side surface of the beam, and the support fitting 3 is attached to the nut. . When the nut is not insert-molded, it is preferable to insert-mold the steel plate and attach the support fitting 3 using a tapping screw.
[0045]
【The invention's effect】
As described above in detail, in the structure of the pouch or terrace according to the present invention, a foundation beam is provided and a support metal fitting having a support part for supporting a concrete formwork is attached to the foundation beam, and the floor part is supported by the foundation beam. At the same time, the step part is supported by a support bracket, and the support bracket is buried and the back side of the step part is filled with concrete so that the level and street adjustment of the members constituting the floor part and the step part are unnecessary. I can do it. For this reason, it is possible to configure a pouch or a terrace having stable accuracy without being affected by a difference in skill, so that the construction period can be shortened and the construction cost can be reduced.
[0046]
Since the step part is supported by the support bracket attached to the foundation beam and is substantially supported by the base concrete, it exhibits extremely high stability, and only the step part may sink below the floor over time. Absent. For this reason, a crack does not arise between the edge part which comprises a step part and a floor part.
