[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a diversion type base mortar form for forming a base mortar on a foundation.

[0002]

2. Description of the Related Art In general, a conventional mortar method and a simultaneous concrete casting method shown in FIG. The mortar method, as shown in FIG.
A center mortar (commonly known as “manju”) b is laid at the center of the upper end of the rising foundation a, and a steel column d is constructed to form a base e at the lower end.
Is placed on the mortar at the center thereof, and the base is fixed by anchor bolts f implanted on the rising foundation a. Then, the mortar c under the base is injected around the mortar b at the center to cure. It is to let. In the drawing, g is the driven fixing plate, and h is the anchor bolt f.
It is an unbonded sleeve fitted to. The simultaneous concrete casting method is to simultaneously cast the equivalent of the central mortar with the cast concrete of the rising foundation, and in this case, a formwork for forming the equivalent of the central mortar by unequal angle iron or the like is used. It is used as a discarded plate by being supported by an upper portion of the anchor bolt or by a support member erected above the anchor bolt.

[0003]

However, in the mortar method, the mortars b and c are apt to peel off from the foundation a, not only to cause collapse due to insufficient strength, but also to take considerable plastering work, and the mortar requires foundation concrete m. However, there is a drawback in that a separate curing period is required, and the number of steps increases the risk. In addition, the simultaneous concrete casting method requires a formwork as a discarded plate for each piece, resulting in high costs,
Further, there are disadvantages such as insufficient fixing of the formwork, difficulty in accuracy, and troublesome mounting. The present invention seeks to eliminate these disadvantages.

[0004]

Means for Solving the Problems In order to achieve this object,
In the present invention, the frame 21 is attached to the upper end of the anchor bolt f of the foundation a.
A hanging frame 22 which is removably mounted through the hanging frame, an appropriate number of hanging bolts 3 are hung from the hanging frame, and the form main body 1 is equipped with the hanging bolts so as to be capable of level adjustment. .

[0005]

In operation, a suspension frame 22 is attached via a frame 21 to the upper end of an anchor bolt f disposed at a key point before the foundation concrete is cast.
Form body 1 suspended from the suspension frame via suspension bolts 3
Is adjusted with each hanging bolt 3. Next, the foundation concrete m is cast.
Is used as a leveler, and a foundation concrete m is cast to the lower end of the form body 1. Then, when the poured concrete loses fluidity, concrete is further poured into the form body 1 (concrete simultaneous casting method) or mortar is filled and hardened. Thereafter, the suspension frame 22 to the mold body 1 are disassembled and removed, cleaned, and diverted to another. Also, a steel column d is constructed on the center mortar or the center mortar equivalent b thus formed, and the lower end base e is placed on the center mortar or the center mortar equivalent, and The base e is fixed with the anchor bolt f implanted on the rising foundation a, and then the mortar c under the base is poured around the central mortar or the central mortar equivalent b and hardened. In addition,
The mortar c under the base may be deployed in advance.

1 to 4 show an embodiment of the present invention. In the figure, a is a rising foundation, 1 is a mold body for forming a central mortar b provided at the center of the upper end of the rising foundation, and 22 is a frame body 21 at the upper end of an anchor bolt f of the rising foundation a. The hanging frame 3 which is detachably attached to the hanging frame 3 is an appropriate number of hanging bolts hanging down from the hanging frame and hanging the form body 1. The rising foundation a is constructed by placing a discarded concrete j on the excavated ground surface i, arranging a fixing plate g thereon via an angled leg k, and erecting an appropriate number of anchor bolts f from the fixing plate. , Applying the reinforcement p as appropriate,
The foundation concrete m is cast to the upper part of the anchor bolt f. The mold body 1 is formed in a flat rectangular shape by an angle. As shown in FIGS. 3 and 4, a pair of L-shaped mold members 11 are butted against each other,
Jointed with bolts 12 so that they can be separated, and cap nuts at the four corners
13 are raised, and the lower ends of the suspension bolts 3 are screwed. The suspension frame 22 is composed of a pair of suspension angles, and is detachably mounted on a middle part of a flat frame-shaped frame 21 formed with a flat plate with a fastening hardware 23.
Through holes are drilled at the four corners of the bracket, and are detachably fitted to the anchor bolts f, and are tightened with nuts n screwed to the anchor bolts. Note that the anchor bolt f also has a frame 21 which is fastened with a nut n and buried in the foundation concrete m at the lower portion.
It is a pair with the upper frame 21. Each of the suspension bolts 3 screwed to the cap nut 13 has an upper part penetrated through a through hole formed in an appropriate place of the suspension frame 22, and is screwed with a nut 31 to be suspended from the suspension frame 22. The vertical movement can be adjusted by screwing. That is, the level of the mold body 1 can be adjusted. Of course, disassembly is also possible.

[0007]

According to the present invention, before the foundation concrete is cast, the suspension frame 22 on which the formwork body 1 is suspended via the suspension bolts 3 is attached to the upper end of the anchor bolt f. Since the assembling is extremely easy, and the level of the form body 1 is adjusted by each hanging bolt 3, the form body 1 can be firmly and precisely positioned in a fixed position, and Since the foundation concrete m can be cast to the lower end of the mold body 1 using the frame body 1 as a leveler, the casting can be easily performed, and therefore, the construction can be performed easily, reliably, quickly, and with less labor. When the fluidity of the foundation concrete m is lost, concrete is further poured into the form body 1 or mortar is filled and hardened, so that the central mortar or the central mortar phase is hardened. Object b can be provided strong and without integrally peeling, may be applied risk reduced in a short period. Further, the formwork body 1 does not need to be buried as a discarded plate, and can be disassembled and removed together with the suspension frame 22 and the suspension bolts 3 after construction, and can be diverted to another. Become.
