2. Description of the Related Art Recently, Japanese Patent Application No. 6-5141 proposed by the applicant of the present invention has been proposed in order to improve sound insulation performance and heat insulation performance.
There is a concrete composition described in No. As shown in FIG. 8, this concrete structure is constructed by sequentially stacking a lightweight cellular concrete panel 5 and a waterproof material 6 on a reinforced concrete 2 having a slope, and as shown in detail in FIG. It is constructed by using the separator 1 with a support plate and the slicing bolt 14. As a construction state thereof, the lightweight cellular concrete panel 5 in which the plurality of nuts 3 with washers are embedded is positioned at a predetermined interval on the inclined form frame 11, and the separator 1 with the support plate 1 is placed.
The male screw 9a at one end of the supporting rod 9 is screwed into the nut 3 with washer, while the male screw 9b at the other end is inserted into the mold 11, and the lightweight cellular concrete panel 5 is supported by using the mold 11 as a base. ing.

As for the supporting state, the tip of the support rod 9 is located substantially in the middle of the nut 3 with washer, and the tip of the male screw 9b at the other end of the support rod 9 is projected from the back surface of the form frame 11, The support plate 10 on the male screw 9a side at one end is in contact with the back surface of the lightweight cellular concrete panel 5, and the support plate 10 of the male screw 9b at the other end is in contact with the surface of the mold 11. According to this state, the lightweight cellular concrete panel 5 is supported while securing a space for forming the reinforced concrete 2 between the lightweight cellular concrete panel 5 and the formwork 11.

Further, in order to support the loaded weight when the reinforced concrete 2 is formed, a nut 3 with a washer embedded in a lightweight cellular concrete panel 5 is screwed with a slicing bolt 14 from the washer 7 side, ALC plate home ties 12 and form home ties 13 connected to various building materials are respectively screwed to the ends of the cutting bolt 14 and the male screw 9b at the other end of the support rod 9. In that state, the reinforced concrete 2 is formed between the lightweight cellular concrete panel 5 and the form 11. By doing so, the formed reinforced concrete 2 and the lightweight cellular concrete panel 5 are prevented from being easily separated from each other by screwing the nut 3 with the washer and the separator 1 with the support plate.

[0005]

However, in the above-mentioned prior art, the male screw 9a3 at one end of the support rod 9 of the separator 1 with a support plate is slightly screwed into the nut 3 with a washer embedded in the lightweight cellular concrete panel 5. However, in that state, there is a drawback that the nut 3 with a washer easily comes off from the lightweight cellular concrete panel 5, and the lightweight cellular concrete panel 5 is separated from the reinforced concrete 2 to construct a stable concrete structure A of a building. The problem arises that you cannot do it.

In order to sufficiently screw the male screw 9a at one end of the support rod 9 of the separator 1 with a support plate into the nut 3 with a washer embedded in the lightweight cellular concrete panel 5, the nut portion 8 of the nut 3 with a washer is used. There is also a problem that the cost becomes high because it is necessary to lengthen.

Further, the support rod 9 of the separator 1 with the support plate
Since the male screw 9a at one end does not protrude from the lightweight cellular concrete panel 5, it may be tilted in the countersink hole of the lightweight cellular concrete panel 5, and there is a problem that it is difficult to screw the nut 3 with washer on the construction.

Furthermore, when constructing the concrete structure A of the building, the slicing bolts 14 are required in addition to the separator 1 with the supporting plate, so that there is a problem that the number of parts is increased.

According to the present invention, the lightweight cellular concrete panel can be arranged on the reinforced concrete without separating, and the separator with the supporting plate and the slicing bolt are integrally formed and screwed directly to the home tie. An object of the present invention is to provide a concrete component of a building that can be combined, and a separator with a support plate used in the concrete component.

[0010]

[Means for Solving the Problems] Means for achieving the above-mentioned object is to provide an end portion of a separator with a support plate in which a portion including a support plate for preventing slippage is embedded inside the reinforced concrete on the surface of the reinforced concrete. In a concrete structure of a building in which a lightweight cellular concrete panel locked with is disposed, the lightweight cellular concrete panel and the reinforced concrete are fixed to each other with a locking portion at a protruding portion that is previously inserted into the lightweight cellular concrete panel. It is constructed by fixing the members and the concrete forming the reinforced concrete by hardening.

Further, in a separator with a support plate in which a support plate is attached to the outer peripheral surface near the thread cutting end of the male screw formed on both ends of the support rod, the outer peripheral surface of the male screw at least at one end of the support rod is substantially at the middle portion. There is a cutout groove that can be cut off.

Further, a protrusion is attached to the outer peripheral surface of the support rod in the vicinity of a substantially middle portion thereof.

By the above means, the lightweight cellular concrete panel and the reinforced concrete are not easily separated because they are locked at the end of the separator with the support plate in which the part including the support plate for preventing slippage is embedded in the reinforced concrete. Becomes And, in that state, the locking portion of the protruding portion of the fixing member previously inserted into the lightweight cellular concrete panel,
Since it is embedded in the reinforced concrete and exerts a locking action, it is more firmly fixed.

Further, since the outer peripheral surface of the approximately middle portion of the male screw at least one end of the support rod is provided with a notch groove,
Cover the tip of the male screw with a cutting pipe, etc.
By repeating turning and the like, the approximately middle portion of the male screw can be cut, and a part from the approximately middle portion of the male screw to the tip portion can be cut off.

Thus, the separator with a support plate capable of cutting the male screw at least at one end of the support rod is suitable for use in constructing a concrete structure such as a roof base, a floor base, and inner and outer walls, First, as a method of using the separator with a support plate, insert a male screw at the other end of the support rod into the formwork so that it stands upright, and at a predetermined interval from the surface of the formwork, a plurality of nuts with washers are embedded. Is
In addition, the lightweight cellular concrete panel in which the fixing member having the locking portion at the protruding portion is inserted in the thickness direction is positioned, and the male screw at one end of the support rod is screwed into the nut with washer. To use. In this case,
A part of the male screw from the notch groove provided in the male screw at one end of the support rod to the tip portion is projected from the surface of the lightweight cellular concrete panel.

Then, the home tie for ALC plate and the home tie for formwork, which are respectively connected to the building material, are screwed into a part of the projected male screw and the male screw at the other end, respectively, so that the loaded weight of the reinforced concrete is supported. Place concrete between the lightweight cellular concrete panel and the formwork.
Next, the ALC plate home tie and the formwork home tie are sequentially removed, and then a cutting pipe is put on the tip of the male screw protruding from the surface of the lightweight cellular concrete panel to right, left, up, down, or the like. Repeat several times to cut the notched groove of the male screw, and cut off a part of the male screw from the notched groove to the tip. Then, a waterproof material is laid on the surface of the lightweight cellular concrete panel which is flush with no protrusions to carry out waterproof treatment, thereby constructing a concrete structure of a building.

In this case, if a protrusion is attached to the outer peripheral surface of the support rod of the separator with the support plate in the vicinity of the substantially middle portion, the protrusion is locked in the reinforced concrete. The fall prevention of the separator with the support plate is enhanced.

Further, the separator 1 with a supporting plate is
As shown in FIG. 2, male screws 9a and 9b are formed at both ends of the rod-shaped support rod 9, and the male screw 9a at one end is formed.
A notched groove 9c is provided on the outer peripheral surface of substantially the middle part of the above, and a circular support plate 10 is attached to the outer peripheral surfaces near the thread cutting ends of the male screw 9a at one end and the male screw 9b at the other end. It is a thing. The separator 1 with a supporting plate shown in FIG. 1 is formed by cutting a notch groove 9c provided in the male screw 9a at one end of the supporting rod 9 shown in FIG. Is removed. The support plate-equipped separator 1 configured in this way is
Support rod 9 is inserted through the thickness direction of reinforced concrete 2
Of the male screws 9a and 9b formed at both ends of each of them protrude outside the reinforced concrete 2, and the male screw 9a at one end of the male screws 9a and 9b is screwed to the nut portion 8 of the nut 10 with washer embedded in the upper surface of the lightweight cellular concrete panel 5. Has become. A pair of support plates 10 are attached to the outer peripheral surfaces near the threaded ends of the male screws 9a and 9b on both ends of the support rod 9 of the separator with a support plate 9 to hold the reinforced concrete 2 therebetween.

Since the supporting rod 9 of the separator 1 with the supporting plate is immersed in the reinforced concrete 2, it is preferable that the supporting rod 9 is formed of a member having excellent corrosion resistance. Further, although the support rod 9 has a round cross-sectional shape in the drawing, it is not particularly limited to that shape. Furthermore, the concrete structure A of the building may use the separator 1 with a support plate that has been conventionally used.

By being constructed in this manner, the concrete structure A of the building has a nut 3 with a washer embedded in the upper surface of the lightweight cellular concrete panel 5 and a separator 1 with a support plate that is inserted through the reinforced concrete 2. By the connection, the lightweight cellular concrete panel 5 and the reinforced concrete 2 are not easily separated from each other. In that state, since the locking portion 4a of the protruding portion of the fixing member 4 which is previously inserted into the lightweight cellular concrete panel 5 is embedded in the reinforced concrete 2 to exert the locking action, it is more firmly fixed. Has become.

As a method of constructing a concrete structure A of a building using the separator 1 with a support plate constructed as described above, for example, as shown in FIG. 3, a plurality of nuts 3 with washers are embedded. The lightweight cellular concrete panel 5 is placed at a predetermined distance from the surface of the formwork 11 that is inclined in one direction, and in that state, the separator 1 with a support plate is placed.
The male screw 9b at one end of the support rod 9 is screwed into the nut 3 with washer, while the male screw 9b at the other end of the support rod 9 is inserted into the insertion hole 11a of the mold 11, and the mold 11a is used as a base for lightweight. Support the cellular concrete panel 5. At this time,
The pair of support plates 10 are surely brought into contact with the lightweight cellular concrete panel 5 and the formwork 11. Further, the attached state of the separator 1 with a support plate is preferably such that the support rod 9 stands upright with respect to the lightweight cellular concrete panel 5 and the formwork 11. Furthermore, the washer nut 3 is optimally attached to at least four corners of the surface of the lightweight cellular concrete panel 5, but it is best to set the number of attachments and the attachment positions according to the construction conditions. Good.

The length from the cutout groove 9c of the male screw 9a at one end of the support rod 9 to the support plate 10 is preferably equivalent to the thickness of the lightweight cellular concrete panel 5. By doing so, the lightweight cellular concrete panel 5 can be stably and reliably supported, and the nut 3 with washer does not easily come out from the lightweight cellular concrete panel 5. Moreover, it is preferable to set the attachment distance between the pair of support plates 10 of the support rods 9 so as to correspond to the concrete thickness, and the reinforced concrete 2 can be formed with an arbitrary thickness. The shape of the pair of support plates 10 is not particularly limited.

With the separator 1 with a support plate supporting the lightweight cellular concrete panel 5 and the formwork 11, a notch provided in the male screw 9a at one end of the support rod 9 protruding from the surface of the lightweight cellular concrete panel 5. AL, which is connected to various building materials, on a part from the groove 9c to the tip and on the male screw 9b at the other end protruding from the mold 11 respectively.
The C-plate home tie 12 and the formwork home tie 13 are screwed together so that the loaded weight when the reinforced concrete 2 is formed can be held. Next, in that state, ready-mixed concrete is poured between the lightweight cellular concrete panel 5 and the formwork 11 and cured to form the reinforced concrete 2.

After that, the home tie 12 for ALC plate and the home tie 13 for formwork are removed, and a part of the male screw 9 from the notch groove 9c to the tip is covered with a cutting pipe (not shown) or the like. To do. Then, the cutting pipe is repeatedly left and right, up and down, swiveled, etc. to cut the cutout groove 9c provided in the male screw 9a at one end of the support rod 9, and the cutout groove 9c from one end of the support rod 9 to the tip portion is cut. Male screw 9
Is cut off to make the surface of the lightweight cellular concrete panel 5 flush. Then, a waterproof material 6 is laid on the flush surface of the lightweight cellular concrete panel 5 for waterproofing, and the formwork 11 is unframed to construct the concrete structure A of the building. Also, the male screw 9b at the other end of the support rod 9 protruding from the back surface of the reinforced concrete 2
May be excised if unnecessary.

When arranging the lightweight cellular concrete panel 5 on the surface of the reinforced concrete 2, the lightweight cellular concrete panel 5 is preliminarily separated from the reinforced concrete 2 so that the lightweight cellular concrete panel 5 is not easily separated from the reinforced concrete 2. First, a plurality of fixing members 4 such as tapping screws each having a locking portion 4a on the protruding portion are screwed in the thickness direction so as to be projected from the back surface of the lightweight cellular concrete panel 5. By doing so, when the reinforced concrete 2 is formed in the space between the lightweight cellular concrete panel 5 and the formwork 11, the locking portion 4a of the fixing member 4 such as a tapping screw is screwed with the reinforced concrete 2 to have a locking action. As a result, the lightweight cellular concrete panel 5 is not easily separated from the reinforced concrete 2.

As shown in FIG. 4, the separator 1 with a supporting plate may be provided with projections 9d having various shapes on the outer peripheral surface of the supporting rod 9 immersed in the reinforced concrete 2 at a predetermined position. Good. By doing so, the separator with a support plate 1 becomes more difficult to come off than the reinforced concrete 2, and the lightweight cellular concrete panel 5 and the reinforced concrete 2 are more firmly fixed.

Further, the fixing member 4 has a locking portion 4a at the protruding portion.
In addition to the screw shown in FIG. 1, a fixing member 4 having a substantially L-shaped locking portion 4a having a rectangular tip as shown in FIG. 5 may be used as shown in FIG. The fixing member 4 may have a locking portion 4a having a substantially T-shaped tip, and further has a locking portion 4a having a spherical shape formed at or near the tip as shown in FIG. The fixing member 4 may be used. In particular, the fixing member 4 does not easily come off,
In addition, the shape of the fixing member 4 may be any one as long as the lightweight cellular concrete panel 5 and the reinforced concrete 2 do not separate from each other, provided with a locking portion 4a that exerts a catching action at a predetermined position of the fixing member 4. Is not limited to what is illustrated.

When the concrete structure A constructed in this way is used as a roof base, a lightweight cellular concrete panel 5 that has been subjected to waterproofing is used as a base plate, and the surface thereof is made of metal such as Japanese-style roofing or roofing tile roofing. The roof structure of the building may be completed by applying Western-style roofing using planks and slate.

When the floor base is to be used, the lightweight cellular concrete panel 5 that has been subjected to waterproofing is used as a floor board, and the surface thereof is indirectly connected via a base material or directly without using the base material. The interior treatment may be performed by applying a floor covering such as a decorative plate, tiles, carpet, and tatami mat. It is also possible to apply the structure to a movie theater, a theater, etc. by making the floor plate inclined, and to construct a floor base of a building in which the floor plate is horizontal with the ground.

When it is used as a wall base, the lightweight cellular concrete panel 5 that has been subjected to waterproofing is used as an outer wall plate or an inner wall plate, and the surface thereof is indirectly connected via a base material, or no base material is used. The interior / exterior treatment may be performed by directly applying interior / exterior material such as inner / outer wall panels, wallpaper, and tiles.

[0033]

In the concrete construction of the building according to claim 1, the reinforced concrete and the lightweight cellular concrete panel subjected to the waterproof treatment are connected to the separator with the support plate and the nut with the washer, and to the protruding portion. Since it is securely attached by the fixing member having the stop portion, it is not easily displaced and separated, and it is possible to construct a concrete concrete structure of a stable building.

In the separator with a supporting plate according to the second aspect, the lightweight cellular concrete panel and the formwork can be reliably supported in a stable state, and at the same time from the notch groove at one end of the supporting rod to the tip end. Since a part of the male screw can be easily and quickly cut off, the surface of the lightweight cellular concrete panel can be quickly brought into a flush state, and a waterproof material can be easily laid and waterproofed. And
Cost can be reduced because it is not necessary to lengthen the female thread of the washer nut in order to sufficiently screw the male thread at one end of the support rod of the separator with a support plate into the nut with washer embedded in the lightweight cellular concrete panel. . Also, since the male screw at one end of the support rod of the separator with a support plate easily projects from the lightweight cellular concrete panel, it is possible to screw the nut with washer without tilting in the countersink hole of the lightweight cellular concrete panel. It becomes easier. Further, since it is not necessary to use the cut bolts, the number of parts can be reduced.

The separator with a support plate according to claim 3 has the same effect as that of the separator with a support plate according to claim 2, and in addition, the protrusions of the support rod are embedded and locked in the reinforced concrete. In this state, the effect of preventing the separator with the support plate from falling out of the reinforced concrete can be further enhanced.
