[Detailed description of the invention] The present invention relates to a formwork mounting embedding device used to support the formwork for floor-forming to the wall of the building when constructing a concrete building. be.

Conventionally, this type of embedded device has been used in which a nail is integrally attached vertically to the corner of the embedded device, which is provided with a screw tube that penetrates in the horizontal direction. The tool is sealed to the formwork for floor construction, and the end of the support rod is screwed together, and the support rod is fixed to the formwork for side wall construction, then concrete is poured, and after the concrete hardens, the mold is When the frame is removed, the embedded tool is buried with the nail protruding from the concrete wall surface. Therefore, not only is it necessary to cut and remove the nail from the protruding base, but the cut end surface of the nail exposed on the concrete wall surface is There were drawbacks such as rusting and staining the surrounding area.

The present invention is intended to improve these problems, and its specific configuration will be explained based on the illustrated embodiment.
In Fig. 6, the main body of the implant is made of 1& synthetic resin, and includes a substrate portion 1a that is approximately square in shape when viewed from above, and a block portion that is integrally bulged upward from the base portion 1a and also exhibits an approximately parallelogram shape when viewed from above. 1b, and the block portion 1b extends along the diagonal direction of the substrate portion 1a.

Therefore, the upper surface of the corner position of the substrate portion 1a facing on the virtual diagonal line intersecting the extending direction is exposed as a flat surface having a substantially right triangular shape in plan view.

Reference numeral 2 denotes a horizontal horizontal hole opened through the center of the block portion 1b, parallel to the short side of the parallelogram, into which the support rod is received.

Then, in order to screw into the support rod, the horizontal horizontal hole 2
A screw tube 3 is embedded and integrated inside.

Reference numeral 4 denotes a peripheral wall protruding from the four edges of the lower surface of the substrate portion 1a, and the inside surrounded by this wall is recessed into a substantially square shape in plan view as a groove 5 for fitting a mounting plate, which will be described later.・
Ru.

Reference numeral 6.6 denotes a pair of sleeve fitting holes which are bored deep enough to penetrate from the corner position of the base plate part 1a to the continuous block part 1b directly above it, and the so-called entrance part thereof has the square shape. It opens at the corner position of the groove 5.

γ is a substantially square mounting plate that is fitted from below into the groove 5 of the substrate portion 1a, and is also molded from synthetic resin, with the fitting holes 6, Corresponding to 6, a pair of sleeves 8, 8 that can be inserted and removed from this,
It is bulged out upwards.

9.9 is a pair of nails which are penetrated and fixed in advance into the sleeves 8, 8 from above, and their heads 9a.

When the sleeves 9a are locked to the upper end surfaces of the sleeves 8, 8 and cannot be dropped, their sharp tips are exposed downward.

To explain how to use the embedding device constructed as above, first, the sleeve 8, which is protruded from the mounting plate 7, is inserted into the fitting holes 6, 6, which are bored at both corners of the bottom surface of the main body 10 of the embedding device 10, and the base plate 1a. At the same time, the mounting plate T, in which the nails 9, 9 are self-retained in advance, is inserted into the concave groove 5 on the lower surface of the base plate portion 1a.
The mounting plate 7 and the embedded tool main body 1
and assemble.

Next, a formwork a is assembled to form a concrete floor.
Nails 9, 9 protruding from the lower surface of the mounting plate T at predetermined locations,
The upper surface of the block portion 1b of the main body 1 of the embedding device is hammered into place to bring the lower surface of the mounting plate 7 into close contact with the upper surface of the formwork a.

At this time, the upper surface of the block part 1b is hit with a hammer or the like, and the mounting plate 7 and the fitting hole 6 in close contact with the base plate part 1a are
The signal is transmitted to the nail 9 through the sleeve 8 fitted to the nail 90.
Driving can be performed smoothly and reliably.

After installing an appropriate number of embeddings at predetermined locations on the formwork a, one end of the support rod is fitted into the screw tube 3 provided in the block part 1b of the embedding main body 1, and the other end is attached to the concrete. It is inserted into the sidewall construction formwork C and fixed with appropriate members such as nuts to support the floor construction formwork A in a horizontal state.

Next, concrete is poured to construct the floor d, and after curing the concrete, when the formwork a is dismantled, the mounting plate 7 attached to the formwork a is removed integrally with the formwork a, and is buried. Only the main body 1 remains buried in the concrete wall.

In the above embodiment, the mounting plate T is fitted into the peripheral wall provided on the lower surface of the substrate main body 10 to prevent concrete from adhering to the close contact area between the base plate 1a and the mounting plate 7 due to the peripheral wall 4. However, in the present invention, the mounting plate 7 can be removed from the embedding main body 1 when the formwork is dismantled without providing such a peripheral wall 4.

As described above, in the formwork mounting embedding device according to the present invention, the groove 5 for fitting the mounting plate is provided in the substantially square substrate portion 1a of the main body 1 of the embedding device made of resin. 1
The block portion 1b, which is integrally bulged upward at both ends of the arrow A, is formed into a substantially parallelogram shape extending along the diagonal direction of the substrate portion 1a when viewed from above, and the short side of the parallelogram shape is located at the center of the block portion 1b. A horizontal horizontal hole 2 parallel to the base plate 1a is opened through the horizontal hole 2, and a support rod receiver is inserted into the horizontal hole 2, and a threaded cylinder 3 for screwing is embedded and integrated. A plurality of sleeve fitting holes 6, 6 are formed with a depth such that the sleeves 8, 8 can be inserted into and removed from the fitting holes 6, 6, and a plurality of sleeves 8, 8 are press-fitted into the fitting holes 6, 6 so as to be removable.
A substantially square synthetic resin mounting plate 70 is fitted from below into the groove 5 of a, and is integrally bulged upward at the corner position, and nails 9, By penetrating the nails 9 so that they cannot fall, the plurality of nails 9, 9 can be assembled and set on the implant main body 1 at once via the common mounting plate 7 with the sleeves 8, 8, and the mold can be removed during disassembly. Since it is set so that it can be attached to the frame a side at the same time, the conventional problem mentioned at the beginning is solved, and there is no need to cut two nails protruding from the concrete wall after dismantling formwork a. At the same time, you can work safely and there is no need to worry about rust.

In particular, in the case of the present invention, the sleeves 8, 8 through which the plurality of nails 9, 9 pass are not independent of each other, but are integrally bulged from the corner positions of the mounting plate T, and are common to the plurality of sleeves 8, 8. The implant main body 1 is self-retained together with the mounting plate 7 and has a recessed groove 5 for fitting the common mounting plate 7.
Since the plurality of nails 9 are formed on the substrate portion 1a of
, 9 can be efficiently assembled and set into the embedded device main body 1 all at once, and the effect becomes more pronounced as the number of nails 9, 9 increases.
The assembled and fitted state is also extremely stable as a whole due to the interposition of the mounting plate 7.

In addition, the plurality of nails 9, 9 are integrally self-held by the mounting plate 1 with a large surface area, and the mounting plate 7 comes into close contact with the formwork a under a dog contact pressure. Even when the formwork a is dismantled after concrete is poured and cured, the plurality of nails 9, 9 will surely adhere to the formwork a side, and there is no risk that each of them will remain on the concrete wall side. .

Even when the nails 9, 9 are removed from the formwork a, the work can be efficiently completed at once via the mounting plate 7.

Further, the fitting holes 6, 6 of the sleeves 8, 8 are bored deep enough to enter the block part 1b from the base plate 1a of the implant main body 1,
The hammering force applied from above to b is completely transmitted to the plurality of nails 9°9 press-fitted into the fitting holes 6, 6, and the swelling of the block portion 1b causes the concrete wall surface to It is also possible to increase the force of fixing the rod to itself and the force of resisting the tension of the support rod.

In other words, when concrete is poured in the installed state shown in Fig. 4, the support rods will receive tensile force along the longitudinal direction in the direction in which the side wall construction formwork C exists. A horizontal horizontal hole 2 for receiving the support rod is formed in a rigid block portion 1b protruding from the base plate portion 1a.
The block portion 1b is formed as a substantially parallelogram extending in the diagonal direction of the substrate portion 1a, and the horizontal hole 2 is arranged parallel to the short side of the block portion 1b. The long hypotenuse forming the parallelogram acts to disperse and weaken the tensile force of the support rod, and in addition, a plurality of grooves 5 are formed in the groove 5 of the base plate 1a which is continuously integrated with the block portion 1b. Since the common mounting plate 7 is fitted to the nails 9, 9, the embedded fixture main body 1 can be buried in a stable state without being affected by any adverse effects from concrete pouring, that is, without causing distortion or deformation. It is possible to do so.

As a result, during disassembly, both the mounting plate 7 with sleeves 8 and 8 and its main body 1 can be removed reliably and smoothly, and can be attached to the formwork a side.
