Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a concrete foundation formwork method and an assembling rebar used in the method.

[0002]

2. Description of the Related Art Conventionally, as shown in FIGS. 12 to 14, the following basic formwork method has been generally used as a basic formwork method for a wooden building. That is,
In this method, a splitter stone 101 is compacted using a rammer on the ground, which is a root excavated in advance, and a discarded concrete 102 is cast on the compacted stone 101. Then, the width reinforcements 106, 106 are arranged at regular intervals on the upper surface of the discarded concrete 102 via the spacer 104, and then the cloth reinforcements 108, 108 are bound so as to be orthogonal to the width reinforcement 106, and assembled in a lattice. Installed and basic reinforcement 110
Place. The width reinforcement 106 at the center of the basic reinforcement 110
The vertical bars 112, 112 are bundled and erected in the direction perpendicular to the base reinforcing bar 110 at the intersections 109, 109 between the reinforcing bars 108 and the reinforcing bars 108 so that the vertical bars 112, 112 are perpendicular to the vertical bars 112, 112. The horizontal bars 114 are tied horizontally to arrange the assembly reinforcing bars 116 (see FIG. 12). This rebar 1
16 and the footing 12 of the cloth foundation 120
A pair of inner base formwork 130 and outer base formwork 131 for casting the two parts are erected so as to oppose each other so as to surround the assembled reinforcing bar 116, and a separator 132, a horizontal flutter 134, and a foam tie are formed. (Registered trademark) 136 to secure the concrete placing space for the footing 122 by tightening and fixing so as not to spread outward or fall inward.
The footing 122 is formed by casting concrete (see FIG. 13). Then, after the concrete casting of the footing 122 is completed, the inner foundation formwork 130 and the outer foundation formwork 131 are disassembled, and the above-described footing 122 is removed.
In the same manner as in the formwork assembly, the foundation formwork 140, 141 of the underground beam upper portion 124 of the cloth foundation 120 is erected, tightly fixed, and concrete is cast, and the underground beam upper portion 1 of the fabric foundation 120 is mounted.
The fabric foundation 120 is constructed by forming 24 (see FIG. 14).

[0003] Incidentally, such a series of basic formwork works are classified into work by a civil engineer and work by a formwork carpenter and a reinforcing steelwork, and both require skilled skills. In other words, each requires a special technique, civil engineering work such as root cutting, ramming and the like is performed by civil engineering workers, formwork is performed by formwork,
Actually, each of them is performed by a different skilled worker, such as rebar construction work such as rebar construction work. So, for example,
It is difficult for formworkers to carry out rebar work, and in the construction industry where the number of skilled workers is decreasing these days, these workers are scarce at the site, and when necessary, In many cases, there is no professional worker on site, and work cannot be performed by a substitute worker. As a result, there has been a problem that the construction period is delayed.

For this reason, recently, as shown in FIG. 15, a base reinforcing bar 210 assembled by welding a width bar 206 and a cloth bar 208 in a grid pattern, and a vertical bar 212 and a horizontal bar 214 by welding. It is composed of the rising bars 211 assembled, and rises at intersections 209 and 209 between the width bars 206 and the cloth bars 208 at the center of the base reinforcing bars 210 so as to be able to stand vertically in relation to the base reinforcing bars 210. Reinforcing bar 211 to basic reinforcing bar 210
A so-called assembled basic reinforcing bar 200 connected by a clip member 213 provided with a spring material is used. That is, if this assembled basic reinforcing bar 200 is used, the folded up basic reinforcing bar 200 is disposed on the upper surface of the discarded concrete 102 at the site, and then the rising bars 211 are simply erected in the vertical direction with respect to the basic reinforcing bar 210. Since assembly rebars can be constructed, it has attracted attention because foundation formwork can be carried out only by unskilled formwork.

On the other hand, when such a cloth foundation is constructed,
In a cold region, the ground may freeze more than 80 cm in the winter, and the freezing of the ground raises the cloth foundation imbalancedly, causing the design strength of the building to be out of order or causing breakage. Therefore, when a foundation for a house is constructed in a cold region, as shown in FIG. 16, a driving foundation form in which the foundation form itself is made of a synthetic resin such as a resin foam having heat insulating properties is used. I have.

[0006]

By the way, as shown in FIG. 16, a pair of inner foundation forms 4 is used in a driving foundation form made of synthetic resin having heat insulation as described above.
The concrete foundation space 401 is formed by arranging the outer foundation formwork 401 and the outer foundation formwork 401 at a fixed interval with a separator 432 therebetween. However, in this case, the low temperature of the outside air is transmitted to the concrete portion of the cloth foundation or the inside of the building through the separator 432, the horizontal flap, the foam tie 436, and the like, so that the heat insulating property cannot be maintained.

For this reason, as shown in FIG. 17, recently, a driving-type inner base formwork 301 and an outer base formwork 3 made of a synthetic resin foam for setting a cloth base.
A fabric base is cast by using a driving-type base frame member 300 including a base member 02 and a separator 303 integrally formed between the two forms to separate the two forms 301 and 302 by a predetermined distance. ing.

However, in the basic form member 300 as shown in FIG. 15, the vertical streaks and the horizontal streaks must be assembled by sewing the gap 304 of the separator 303.
It was a very complicated task. Therefore, in order to save labor in assembling the rebar using the basic form member 300,
Although it is conceivable to use the assembled basic reinforcing bar 200 as shown in FIG. 15, in this case, if the foundation formwork is to be performed, the folded assembled basic reinforcing bar 200 is placed on the upper surface of the discarded concrete 102 at the site. And riser 2
11 is erected in the vertical direction with respect to the base rebar 210, and when the base form member 300 is to be discarded from above and is to be erected on the concrete 102, the separator 303 can be used as the horizontal bar 214 of the assembled base rebar 200. To become
It was impossible to use the conventional assembled base reinforcing bar 200 for the base form member 300.

In view of the above situation, the present invention provides a foundation comprising an outer foundation form, an inner foundation form, and a separator disposed between the two forms to separate the two forms by a certain distance. Formwork members are erected to surround the assembling base rebar,
Basic formwork method that can easily and securely place the basic formwork members in the specified position without forming the concrete placing space between the formwork and holding the assembly base rebar without any trouble. , And an assembling base reinforcing bar therefor.

[0010]

[0012] In the foundation form method using the assembled basic reinforcing bar, the mounting position of the horizontal reinforcing bar is set in a state where the vertical reinforcing bar is erected in the vertical direction with respect to the basic reinforcing bar.
Since it is installed so as to be located above the upper end position of the footing and below the lowermost separator position of the base form member, the base form is bent so as to surround the assembled base reinforcing bar. When the member is disposed on the concrete discarded from above, the separator does not get stuck on the horizontal streaks of the rising bars of the assembling base rebar. Therefore, since the foundation form member can be easily and erected at a predetermined position on the concrete by discarding the foundation form member from above, a concrete casting space can be reliably formed, and concrete can be cast to construct a cloth foundation. it can.

Further, according to the foundation formwork method of the present invention, in the above-mentioned foundation formwork method, the horizontal bars of the rising bars of the assembled base bars are omitted, and only the vertical bars are connected to the base bars so as to be erected.

And an assembling basic reinforcing bar.

Further, the foundation formwork method of the present invention comprises a base reinforcing bar assembled in a lattice shape with a width bar and a reinforcing bar, and a vertical bar mounting portion provided at a connecting position of the width bar and the reinforcing bar. While arranging the assembling foundation rebar constructed on discarded concrete,
A vertical bar is attached to the vertical bar mounting member of the basic reinforcing bar to form a reinforcing bar, and the outer and inner base frames and the inner and lower base frames are separated from each other by a certain distance to separate the both frames. A base form member consisting of a separator and a separator disposed on the base foundation member is erected so as to surround the assembled base reinforcing bar, and then a concrete foundation is cast between the form forms to construct a cloth base. This is the basic formwork method.

Further, the assembled basic reinforcing bar of the present invention comprises a basic reinforcing bar assembled in a lattice shape with a width reinforcing bar and a reinforcing bar, and a vertical bar mounting portion provided at a connecting position of the width reinforcing bar and the reinforcing bar. This is the basic rebar to be assembled.

In the foundation form method using these assembled foundation rebars, since there is no horizontal streak constituting a rising streak, the foundation form member is discarded from above so as to surround the assembled foundation rebar and is placed on concrete. When arranging, the separator does not come into contact with the rising bars of the assembling base rebar at all. Therefore, the foundation form member can be discarded from above and more easily and easily erected at a predetermined position on the concrete, so that the concrete placing space can be reliably formed, and the cloth foundation is constructed by placing concrete. Can be.

In the assembled basic reinforcing bar 10 of this embodiment, the third
In the embodiment shown in FIG.
The vertical bar mounting portion 30 is inserted vertically into the base reinforcing bar 13 and fixed upright, and the rising bar 18 is inserted in the vertical direction with respect to the base reinforcing bar 13 at the intersection 14 between the 11 and the central reinforcing bar 12B. And a vertical streak mounting portion 30 formed of an annular member having a hole 32 for inserting and fixing it vertically. In the present embodiment, the vertical streak mounting portion 30 made of another member is used. However, it is also possible to form a hole by bending a width streak or a cloth streak, for example. Further, a foundation form method for constructing a fabric foundation using the assembled foundation rebar of the present invention configured as described above is basically the same as that of the third embodiment, and will not be described.

In the above-described embodiment, the integrated foundation frame member 300 corresponding to the footing portion of the cloth foundation and the upper part of the underground beam is used. However, a synthetic resin for casting the footing portion of the cloth foundation is used. After the footing of the cloth foundation is cast using the driving-type footing inner base formwork and the footing outer base formwork made of foam, the inner base formwork and the outer foundation made of synthetic resin foam are placed above the footing. The upper part of the underground beam of the cloth foundation is driven by using a driving type base frame member composed of a mold and a separator integrally formed between the two forms to separate the two forms from each other. It is also possible.

[0039]

The foundation formwork method according to the present invention and the assembling foundation reinforcing bar for the same are arranged such that the horizontal streaks of the rising bars of the assembling foundation rebar are located above the upper end position of the footing in the upright state, and that Since the base reinforcing bar assembled so as to be located below the lowermost separator position was used,
When laying the foundation form member above the concrete to form a concrete placing space so as to deflect the assembling base rebar, the separator does not stick to the horizontal streaks of the rising bars of the assembling base rebar. Since it can be easily and erected at a predetermined position on the discarded concrete, a concrete casting space can be simply and reliably formed, and concrete can be cast to construct a cloth foundation.

Further, the foundation formwork method of the present invention and the assembling foundation reinforcing bar for the same are omitted from the horizontal streaks of the rising bars of the assembling foundation reinforcing bar, and only the vertical bars are connected to the foundation reinforcing bar so as to be able to be erected. Since the reinforcing bars are used, there are no horizontal bars constituting the rising bars, so when the base form member is disposed above the concrete so as to deflect the assembled reinforcing bars, when the separator is mounted on the concrete, There is no stuck in the muscle. Therefore, the foundation form member can be discarded from above and more easily and easily erected at a predetermined position on the concrete, so that the concrete placing space can be reliably formed, and the cloth foundation is constructed by placing concrete. Can be.

Accordingly, the assembled reinforcing bar can be constructed simply by arranging the rising reinforcing bar in the vertical direction with respect to the basic reinforcing bar after disposing the folded basic reinforcing bar on the upper surface of the discarded concrete at the site. The foundation formwork can be performed only by unskilled formworkers.

Further, the width-base formwork method and the assembling base reinforcement therefor include a base reinforcement assembled in a lattice shape with the width reinforcement and the reinforcement, and a vertical reinforcement provided at a connecting position of the width reinforcement and the reinforcement. Since the vertical bars are attached to the vertical bar mounting section and the reinforcing bars for the foundation are constructed by using the assembled basic reinforcing bar composed of the mounting section, in this case also, there is no horizontal bar, so the base form member is When placed on concrete that is discarded from above, the separator does not come into contact with the rising bars of the assembling base rebar at all.

Therefore, after arranging the base reinforcing bars assembled in a grid pattern with the width bars and the cloth bars on the upper surface of the discarded concrete at the site, the vertical bars constituting the rising bars are mounted on the vertical bar mounting portion. Since the assembling rebar can be constructed simply by erected in the vertical direction with respect to the foundation rebar, foundation formwork can be performed only by a formwork unskilled as a rebar.

As described above, in a series of foundation form work, the form work and the reinforcing work can be simultaneously and easily performed without the need for skilled and special skills such as form carpenters and reinforcing bars. This is an extremely excellent invention which does not cause problems such as delaying the construction period even in the construction industry where the number of skilled workers is decreasing in recent years.
