Description

Description: TECHNICAL FIELD The present invention relates to an inclined surface structure such as a roof or a floor inclined in the vertical direction of a building and a method for producing the same.

[Problems to be Solved by Prior Art and Invention]

Conventionally, as a roof of a building, as shown in FIG. 9, a roof made of reinforced concrete and vertically inclined is known. Such a roof supports the temporary frame plate (2) by inclining vertically on the temporary support column (1) and forms a plane parallel to these plate surfaces above the temporary frame plate (2) to form a reinforcing bar assembly. After arranging the solid (3), concrete is placed on the temporary frame (2) to embed the rebar assembly (3), and after the concrete (8) hardens, the temporary support column (1) and the temporary frame plate It is made by removing (2).

However, in such a conventional roof, after the concrete is poured, it flows downward due to the fluidity of the fresh concrete, that is, to the eaves side, and the thickness of the concrete at the lower end of the slope is shown by the chain double-dashed line in FIG. It will thicken like this.
So, using a manual leveling tool commonly called a dragonfly, the concrete after pouring is scraped up,
Despite a great deal of work, there was a problem that the hardened concrete still had a considerably thicker lower end.

Regarding this type of roof structure, the structure described in Japanese Patent Application Laid-Open No. 57-13754879 is known. In the present invention, a square corrugated iron plate or a corrugated iron plate is attached on a concrete panel provided on a rafter, and a concrete layer is formed by pouring concrete on the foundation member formed by laying a wire mesh on the concrete layer, and further It is a double structure in which waterproof mortar is applied on top to form a mortar layer.

According to this structure, since it is a double layer, it is excellent in strength, but the concrete layer alone forms a thick raised concrete layer on the eaves side as shown in FIG. However, after all, there is a problem that an inclined surface having a substantially uniform thickness that fits the roof slope can only be formed by adding the mortar layer.

Furthermore, the synthetic floorboard described in Japanese Utility Model Publication No. 55-52974 is also known. This invention embeds a reinforcing steel material in contact with the top surface of the ribs, and layer a post-cast concrete layer on the floor slab with precast concrete ribs, which is formed by projecting a reinforced concrete shear slip prevention material from the rib top surface. In the case of forming a post-cast concrete layer, there is no problem in the case of a horizontal surface, but in the case of forming an inclined surface, the above-mentioned problem, that is, a sloping roof It was not possible to solve the drawback that a thick concrete layer was formed on the eaves side of the building.

A first object of the present invention is to solve the above-mentioned conventional problems and to eliminate or reduce the work of scraping concrete after pouring, and the hardened concrete is thick even at the lower end of the slope. To provide a uniform slope.

A second object of the present invention is to provide a method of forming an inclined surface of concrete having a uniform thickness with good workability.

Further, a third object of the present invention is to cover the concrete sloped surface having a uniform thickness with a roof plate, thereby providing a soundproofing performance,
An object is to provide a surface structure having excellent sound insulation performance and heat insulation performance.

[Means for Solving the Problems]

An inclined surface structure of a building according to a first aspect of the present invention is a surface structure in which a reinforcing bar assembly is arranged on an inclined temporary frame plate to form a concrete inclined surface having a desired thickness. The blocks for leveling and blocking the flow are arranged vertically and horizontally with an interval between them so that the lower surface of the block forms the lower surface of the surface structure, and the concrete is embedded between the reinforcing bar assembly and the block. It is configured such that the inclined plate-like body having a thickness substantially equal to the thickness of the block is formed.

A method of constructing a sloped structure structure according to a second aspect of the present invention is a method of supporting a temporary frame plate by inclining it vertically on a temporary support column and forming a plane parallel to the temporary frame plate surface above the temporary frame plate to rebar. In the method of forming a surface structure for disposing an assembly, first, a large number of leveling and flow-stopping blocks are arranged vertically and horizontally in the rebar assembly, and then these blocks are arranged. Is supported on the temporary frame plate, and then the reinforcing bar assembly and the block are embedded with concrete to form an inclined plate-like body having a thickness substantially equal to the thickness of the block. Also, the temporary frame plate will be removed.

The inclined structure for a building according to the third aspect of the present invention is a planar structure in which a plurality of blocks for leveling and preventing flow are made of reinforced concrete having anchor metal fittings in a reinforcing bar assembly having an inclination in the vertical direction. Are arranged vertically and horizontally so as to form a part of the lower surface of the, and the reinforcing bar assembly and the block are embedded in concrete to form a plate having an inclination in the up-and-down direction. The face plate support member is fixed via a fixture fixed to the anchor metal fitting, and the roof plate is fixed on the face plate support member by forming a space between the face plate support member and the concrete.

[Work]

In the first aspect of the present invention, since a number of blocks for leveling and blocking the flow are provided in the inclined reinforcing bar assembly as described above,
Since the concrete that has fluidity after pouring is prevented from flowing down at many points in the vertical direction by the block, it is less likely that the concrete will rise thickly even at the lower end of the inclined surface.

Further, since the block is supported by the rebar assembly and is hardly displaced downward even if the block receives a load to flow down the concrete, the lower end of the concrete is hardly thickened, and each part is almost equal to the thickness of the block. It is possible to form a slanted plate-shaped body having a thickness.

According to the second aspect of the present invention, in addition to the above-described action, it is possible to form an inclined surface of concrete having a uniform thickness with good workability.

According to the third aspect of the invention, in addition to the function of the first aspect of the invention, by covering the concrete sloping surface having a uniform thickness with a roof plate, a sloping surface structure excellent in soundproofing performance, soundproofing performance and heat insulating performance is obtained. be able to.

〔Example〕

 Embodiments of the present invention will be described below with reference to the drawings.

As shown in FIG. 1, a large number of temporary columns (1) are erected, and a temporary frame plate (2) made of plywood or the like is vertically supported on these columns (1) by supporting and fixing the temporary frame plate (2). The reinforcing bar assembly (3) is installed on the frame plate (2) with a vertical inclination so that a plane parallel to the plate surface of the temporary frame plate (2) is formed.

As shown in FIGS. 2 and 3, the reinforcing bar assembly (3) includes reinforcing bars (3a) along the eaves direction and reinforcing bars (3b) orthogonal to these.
And the reinforcing bars (3
c) and are fixed at appropriate intersections.

(4) is a level-fixing and flow-stop block fixed in the rebar assembly (3). This block (4) is relatively thin as shown in FIGS. 2 to 6. It is made of reinforced concrete in which reinforcing bars (5) are braided and embedded in concrete (6), and the upper part (4b) and the lower part (4c) are flanged up and down, respectively, with respect to the cylindrical body (4a). It projects to the outer peripheral side.

The outer diameter section of the lower part (4c) of the block (4) is the upper part of the block (4)
The cutout shape is symmetrical to the outer diameter cross section of (4b), and the upper portion (4b) is formed with a recessed portion (4d) whose upper surface opens. The upper part of the anchor metal fitting (7) is housed in the recess (4d), and the leg portions of the anchor metal fitting (7) are embedded in the concrete (6) of the block (4). Incidentally, the anchor metal fitting (7) is formed in a substantially C-shape having an opening at the bottom.

Prevent concrete (8) from flowing into d). still,
Although not shown, the temporary dam plate is made to rise from the lower end of the temporary frame plate (2), that is, the eaves tip end so as to prevent the concrete (8) from flowing down.

The concrete (8) immediately after being cast on the temporary frame plate (2) has fluidity, but since the block (4) supports the downflow due to the inclination of the concrete (8) at many points in the vertical direction, the concrete (8) ) Is suppressed, and the block (4) is supported by the rebar assembly (3) even if the concrete (8) is subjected to a load that tries to flow down, and the block (4) itself has a considerable weight. Since there is a relatively large frictional resistance between these and the temporary frame plate (2), even if vibration is given by a vibrator etc., not only is it not displaced downwardly of the inclination, that is, the eaves side, but also the body part Concrete is also filled in (4a) so that no gap is created.

Therefore, since the lower end of the slope of concrete (8) does not become too thick, the surface can be flattened after pouring,
Even if almost no scraping work is performed, each part hardens into a disk shape with a substantially uniform thickness. Then, after hardening the concrete (8), the temporary columns (1) and the temporary frame plate (2) are removed. By doing so, the lower surface of the block (4) becomes the same flat surface as the lower surface of the concrete (8), and forms the lower surface of the roof which is a planar structure.

After hardening the concrete (8), as shown in FIG. 3, the styrofoam (19) is broken and the hook (10) of the fixture (9) is hooked on the anchor metal fitting (7), and the hook (10) Presser plate

b) Inner layer material (15) with heat insulation and sound insulation, such as wood blanket,
(16) is laid and supported, the roof plate (17) made of a long iron plate or the like is fixed on the upper plate (13c) of the support member (13), and these are laterally roofed, and the roof plate (17) A space (18) having inner layer materials (16) and (15) is formed between the concrete and the concrete (8) in the upper and lower portions. In the present invention, the block (4) for leveling and blocking the flow is such that a part of the reinforcing bar (5) is extended to the outside of the body (4a) as shown in FIG. When the part (5a) is fixed to a part of the reinforcing bar constituting the reinforcing bar assembly by means such as welding, the displacement of the block (4) can be prevented more reliably.

In addition, the block (4) is attached to the upper part (4
The b) flange may not be provided, and a bolt (20) also serving as a differential line may be hung vertically on the lower portion (4c) as shown in FIG.

In the present invention, the fixture (9) for fixing the face plate support member (13) such as rafter to the anchor metal fitting (7) includes the hook (10), the holding plate (11), the nut (12) as in the above-mentioned embodiment. ) And wedge plate (1
The anchor metal fitting (7) may be a simple bolt without being limited to the one composed of 4), but if the anchor metal fitting (7) is a C type or an inverted groove type with an opening at the bottom as in the embodiment, the anchor metal fitting (7) It is preferable because the position of the hook (10) and the like to be hung on can be adjusted.

In the present invention, the face plate support member (13) and the roof plate (17) can be changed to appropriate roof members, and the inner layer materials (15), (16)
You can change it by omitting one.

Furthermore, the present invention is not limited to the roof as in the above-described embodiment, but can be applied to a floor having a vertical inclination in a theater, for example, and may not require a face plate when the floor is used. In such a case, the face plate and the face plate supporting member may be omitted, and the fixture and the anchor metal fitting may not be needed.

〔The invention's effect〕

As described above, according to the first aspect of the present invention, the inclined surface structure body such as the roof and the floor in which the concrete is inclined in the vertical direction is provided.
The effect of being able to easily provide to a homogenized product in which the work of scraping the concrete is reduced and the bottom end of the slope does not become thick even after the concrete is poured can be easily obtained.

Further, by attaching a vertically symmetrical flange to the shape of the block, it is possible to prevent the reinforcing bar from rising and to obtain an effect that the finish is clean.

Further, according to the second aspect of the present invention, a large number of blocks for leveling out and blocking flow are supported only on the temporary frame plate inclined in the vertical direction, and these blocks are not fixed to the temporary frame plate. In addition, since the block is arranged in the reinforcing bar assembly, the block is hardly displaced in the vertical direction of the slope when placing concrete, and therefore the block can be arranged with good workability. Moreover, the removal of the temporary frame plate after hardening the concrete is as simple as the one without using the block, and if the concrete is placed on the basis of the height of the block, the required thickness can be obtained. The effect is that the thickness of concrete can be controlled very easily.

Further, according to the third aspect of the invention, since the blocks for leveling and blocking the flow made of reinforced concrete having the anchor fittings are used, these blocks are made of the same material as the concrete to be placed and the surface is rough. The block can be reliably integrated with the cast concrete, and the anchor plate can be used to easily and firmly fix the face plate support member. Therefore, the effect that the space structure is provided above the cast concrete and the surface structure to which the roof plate is attached can be easily provided. Moreover, it is possible to obtain an effect that it is possible to provide an inclined surface structure having excellent soundproofing performance, soundproofing performance, and heat insulating performance.

Although the present invention has been described on the premise of an inclined surface, it is needless to say that the present invention can be applied to a horizontal plane structure.
