Description

Detailed Description of the Invention (a) Industrial Application Field The present invention relates to a basic concrete form in which a base concrete form and a foundation concrete form are sequentially assembled, and the base concrete and foundation concrete are poured one after another. Regarding the assembly method.

(B) Prior art Conventional, foundation concrete) 177 As a pouring method, base concrete is poured into the formwork, and after it hardens, the foundation formwork is assembled on the hardened base concrete, and concrete is poured into the formwork. There was a method of pouring fresh concrete into the concrete, and a method of assembling the base concrete formwork and the foundation formwork, and then pouring fresh concrete into the base portion and the foundation portion one after another and curing them as one body.

(c) Problems to be solved by the invention Among the above-mentioned known directions, the former is undesirable because the layers of base concrete and foundation concrete separate, and the latter is undesirable because the foundation concrete is poured while the base concrete is hardening. The base concrete and foundation concrete can be integrally formed.

However, the latter method of assembling formwork involves assembling a base concrete formwork within the root cutting groove, and piling up concrete in a chevron shape at appropriate intervals in the length direction in the middle of the width of this base concrete formwork. The supports called "horses" were pushed in and aligned straight and horizontally, and after the concrete had hardened, the foundation formwork was assembled on the supports, so many piles of concrete were removed. The construction work and the work of inserting supports and adjusting their positions and heights are troublesome, and the foundation formwork cannot be assembled until after the concrete has hardened, so the work time is extremely long. There were some problems.

(d) Means for solving the problem The present invention assembles a base concrete frame in the root cutting groove,
The opposing side frames of the base concrete are connected at multiple points using a connecting support frame that has downward retaining portions at both ends and has a concave portion slightly wider than the mounting interval of the foundation formwork on the upper surface of the intermediate portion, and
The base forms on both sides are fitted into the recesses of the connecting support frames, and the locking steps of the spacing holders are engaged with the lower flanges of the base forms to prevent them from falling off, thereby regulating the lower spacing. , by fitting a spacing retainer to the upper part of the foundation formwork to regulate the upper interval, the connecting support frame serves as a support means for the foundation formwork while regulating the interval between the base concrete forms, and the connection A pair of receiving grooves in the center of the support frame gently regulates and supports the lower position of the foundation formwork, while allowing movement in the width direction to adjust the position of the foundation formwork, supporting the foundation formwork in space. The above-mentioned problem has been solved by making it possible to reliably regulate the distance between the lower parts even when the space is in a closed state.

(e) Putting stones and gravel into the bottom of the root cutting groove and compacting it;
Assemble the base formwork directly or after driving a steel plate on top of it, fit the connecting support frame to the left and right frame plates at an appropriate interval, and then fit the base formwork into the receiving groove of the connecting support frame. The lower part of the connector is fitted and erected, and the lower part interval is regulated while adjusting the position by engaging the locking stepped part of the link, and the interval regulating tool is fitted to the upper part.

In this state, fresh concrete is allowed to flow into the base formwork and foundation formwork.

(f) Example An example of the present invention will be explained with reference to the drawings. The root is cut in accordance with the usual method, and after it is compacted by laying stone and gravel, reinforcing bars are driven directly on top of it, or without being driven in. After placing the reinforcement, set the side frame 1.φ (combine appropriate lengths, for example, 1818 mm and 1363.5 mm depending on the shape and scale of the foundation) and the inner and outer corner frames 8, 12.φ. Arrange them in the position of the adjacent side frames 1.
They are connected by inserting the U-shaped connecting fittings 7 into the holes 4 drilled in the ends of the flanges 3 and the long holes 6 of the side plates 5, and connect them to the foundation. At the corner, the end of the inner side frame 1 is overlapped with the inside of the inner corner frame 8 forming an inverted letter shape, and the above-mentioned U is formed between the hole 11 of the flange 10 of the inner corner frame 8 and the hole 4 of the side frame. The connection is made by inserting the letter-shaped connecting fittings 7, 7 through them.

Also on the outside of the outer corner frame 12, the ends of the side frames 1 located on the outside are overlapped with each other, and a U-shaped connecting fitting 7 is formed in the same manner as the inner corner frame 8.
, 7 are inserted and connected to complete the base formwork assembly.

The connecting support frame 13 is fitted onto the outside of the side frame 1.1 of the base formwork assembled as described above to regulate the interval therebetween.
As shown in Fig. 11, one side of the horizontal part is bent upward and the other side is bent downward, respectively, to form a Z-shape or the like, and the side frame 1 is formed at the lower part near both ends of the hanging part. An engaging portion 13a consisting of a groove into which a plurality of The engaging parts 13a, 13a of the connection support frame 13 are spaced at an appropriate distance, for example, 1818 mm.
It engages with the left and right side frames 1, 1 from above at an interval of , as shown in FIG. 12.

After that, the basic formwork 15 having flanges on the upper and lower sides is
are fitted into two rows of recesses 16 of the connection support frame 13, and their lower portions are connected by spacer retainers 17.

This spacing holder 17 is the one shown in FIG. 13, or any other modification, and has both ends on one side of the plate 18 and is offset toward the center by the same width as the flange of the base formwork 15. At the same time, a locking step portion 21.21 is bored inside the lower part of the standing portions 20.20 at both ends, and the portion is curved or gently curved upward between the pair of standing portions 20.22 on both sides. It is bent, and the outer upper part of the intermediate upright part 22.22 is cut out diagonally, so that the base formwork 15.
When assembling φ, first, the outer edge of the flange is engaged with the locking step portion 21, and the inner edge is attached to the upright portion 22.2.
2, the other side slides down along the inclined surface 22a of the standing portion 22.22 while pushing the curved portion or bent portion downward, and as a result, the standing portion 20 forming the set .22.

Further, a known spacer retainer 23 (see FIG. 14) having two pairs of locking pieces on the outside of the upper part of the opposing base forms 15 and 15 is engaged and connected.

At this time, the base concrete is to be buried at the time of completion, and while the side frames 1 do not have any support even if they are slightly deviated from the normal installation position, the foundation concrete needs to be installed at a predetermined position.

Therefore, accurate positioning of the base formwork is omitted, saving labor.

Then, the basic formwork 15... is fitted into the recess 16... of the connection support frame 13...
3..., the connected foundation formwork 15... is not necessarily in a straight line, and there are some parts that are slightly shifted left and right, but the width of the recess 16... at the top of the connecting support frame 13... As mentioned above, the foundation formwork 15.15 is slightly wider than the set width, so the foundation formwork 15, 15 is connected to the recess 16...
Alignment can be achieved by adjusting the position by moving left and right while being fitted and supported.

In addition, although there may be some height difference between the side frames 1 and 1 that face each other on the left and right, the distance between the side frames 1 and 1 is approximately three times the width of the foundation, so the foundation form 15.15 The difference in height will be small, and the top surface of the foundation will be leveled with mortar, so there will be no practical support.

Once the formwork has been assembled in this way, pour ready-mixed concrete into the base formwork, and when it has hardened to a certain degree, even if the ready-mixed concrete is poured between the base formwork 15. Once the condition is reached that it will not flow out, pour ready-mixed concrete between the foundation formwork 15.15. After curing, remove the base formwork 15 and the connecting support frame 13.
By bending the hanging part of the outer end (the outer part of the engaging part 13a) in a direction parallel to the foundation with an appropriate rear part and removing the U-shaped connecting fitting 7..., the side frame 1φ can be easily removed. be able to.

In addition, the corners of the foundation are connected to the ends of the foundation formwork using the already proposed inner corner frame and outer corner frame.
