Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a device for supporting a concrete formwork in a double-sided form.

When constructing a concrete foundation, place the moon formwork that matches the side shape of the Funkri-1 foundation facing each other, and place concrete between the formwork. By the way, it is necessary to support the formwork when pouring the Funkri-1, and various supporting devices have been used in the past. However, the conventional support 4
-4 There is no equipment that can easily hold the formwork, and it is difficult to support the formwork at the desired height or horizontally.A1
It is 1. Therefore, in order to accurately construct a concrete foundation, the ground must be leveled to k, 'ilE (4+'), which has the disadvantage that the leveling work is time-consuming.

The purpose of the present invention is to eliminate one of the drawbacks of 11. The formwork was supported by adding 1111 adjustment points to adjust the position in the 7FJJ direction, and holding the 7runs provided on the outside surface of the formwork by the recording arms I and I. A supporting device for concrete formwork is characterized by:

Hereinafter, one embodiment of the present invention will be described with reference to the drawings. Figure 1 shows the state of concrete 1))1'', and Figure 2 shows the state after the old concrete was placed. As shown in Fig. 2, the concrete 1/foundation 10 to be constructed has an upright part] 1
and a footing part 12 extending laterally from the lower part of the upright part 11.

As shown in FIG. 1, the lunar steel formworks 20 are arranged so as to face each other. Each (51) frame 20 stands upright on the side surface of the upright portion 11 by λ.
1, an overhanging part 22 that cuts on two sides of the two-part footing part 12, and a hanging part 23 that corresponds to the side surface of the footing part 12. The standing wall portion 21 has a plate shape, and has a plurality of vertical flanges 2.・1 and horizontal 7 runno 25
are arranged in a grid pattern. The overhanging part 22 and the hanging part 23 are formed into a continuous plate, and are connected to the lower edge of the two-part standing wall part 21. Overhang part 22
A hole 2G is formed in a portion near the upstanding wall portion 21 of.

A plurality of supports 3 ( ) are arranged along the longitudinal direction of the formwork 20 . The strut 3 is formed by welding a lower pipe 31 and a rat rod 32 having a male threaded portion 32a on the outer circumferential surface.
3 has been inserted. The upper pipe 33 is provided with two horizontally extending arm abutments 35 and 36. Arm shrine 35
, 36 is the distance between the 2
It is equal to the interval of 25.25 l'1lI7 runno. Each arm portion 4=435, 36 is a protrusion 35a that projects upward.

It has 3Ga. In addition, an adjustment part 34 having a screw head (2 has a threaded part 341 on the inner peripheral surface) is screwed together, and the lower end of the -L two-part pipe 33 is supported by this adjustment member 3...1. There is. As will be described later, the upper pipe 33 is moved downward by the rotation of the barrel adjusting portion 34, and the arm portions 35 and 36 are also moved downwards accordingly. That is, the male threaded portion 32a of the screw rod 32, the adjustment portion 443ll, and the J two-part pipe 33 constitute an adjustment mechanism for adjusting the −L lower position of the arm portions 35, 36. In addition, a handle 31a is provided at the upper part of the lower pipe 31, and a handle 34a is provided at the adjustment part shrine 34.

The formwork 20 is supported by two-part struts 30.

That is, the branch office 30 is inserted through the hole 26 of the overhang 22 and erected on the leveled ground 10 via the support stand 41.

In this upright state, the support column 30 is placed outside the standing wall portion 21 of the formwork 20. Then, the two sides 7 of the standing wall portion 21
The run 25 rests on the arm members 35 and 36, thereby securing 1.
The support 11i is supported by the dead weight of the formwork 20 or the branch 30.
Ru. In addition, the protrusions 35a and 3 of the first part 35 and 36 are
By inserting Cia into the holes 25a, 25a of the horizontal 7 run holes 25.25, rotation of the upper pipe 33 is prohibited, and the state of support of the formwork 0 by the arm shaft 35.3 G is ensured. held. In the two-part support state, hold the handle 31a with one hand to prevent rotation of the lower pipe 31, and hold the handle 3'la with the other hand to move the adjustment part 34.
By turning the arm*IS through part of the pipe 33

is adjusted horizontally.

The formwork 20 has a support part Jr45t which can be expanded and contracted.
+ provides lateral support. The support shrine 50 is
A support rod 51 and a threaded rod 5 screwed onto the end of the support rod S1.
2, and holding the handle 53, the tensioning rod 5
By turning 2, you can adjust the expansion and contraction. One end of the supporting part shrine 50 is connected to a fixed part 55 buried in the ground by a connecting mechanism 54 so as to be able to freely rotate from side to side. By connecting the pond end of the support shrine 5 () to the horizontal 7-run no. Supported or given. Ren+1111+Mechanism 5
(3 has a bottle 57 and a long bottle 5), and by inserting the bottle 58 into the hole 57at of the plate t57 and the hole 25a of the horizontal run 25, it can be inserted into the formwork 20. The supporting part shrines 5 ( ) are connected. Since the bottles 58 are inserted into the holes 25 a of the two horizontal 7-run holes 25 , a stable connected state can be obtained.

The sides II' between the formwork 20 are closed by a two-part end plate 61 and a lower end plate (not shown). Also, formwork 2
A holding fitting 62 is hung on the second part of () to prevent the formwork 20 from spreading during concrete pouring and to maintain a constant distance between the formworks 20. Reinforcing iron 1li7i63 is installed between the formworks 20.

After the formwork support work described in "-", concrete is poured from "-1 part 1" between the formworks 20 and hardened, thereby forming a concrete structure having an upright part 11 and a footing part 12.
IJ118 foundation 10 is constructed. After concrete pouring 2
〜; (After time has passed, in other words, the initial hardening of the concrete has begun.) Around the point 30 is removed. To be more specific, by turning the adjustment member 4, the L pipe 33 moves downward, and the arm shafts 35 and 3 G
Move away from the side 7 runno 25.25 of the formwork 2 (), and move the protrusion 3
5a, 3Ga and hole 25a.

The state of engagement with 25a is also divided by 11. Next, by turning the two-part pipe 3: (, the arm parts 35 and 36 are
Run') 25, 25 is moved in the opposite direction, and in this state the support column 30 is pulled out. Lower pipe 31 of strut 30
It is either buried in the concrete or the concrete has not yet hardened, so it can be removed by pulling it out. In addition,
By surface-treating the lower pipe 31 by painting or the like, adhesion of concrete to 11j can be prevented. As mentioned above, before the concrete 1 hardens, the support of the formwork 20 by the branch office 30 is reduced by 1η, but the shape of the concrete is changed because a certain period of time has passed after pouring and the concrete has become smaller in flow 1. It won't collapse. At the same time as the above-mentioned pulling out of the branch 30, the bottle 58 is pulled out through the hole in the horizontal 7-run no. 25, and the support part 4'45o or the formwork 20 is removed.

After the concrete 1 has hardened, the formwork 20. The end plate 61 is peeled off from the concrete foundation 10.

It should be noted that the present invention is not limited to the two-part embodiment and can be modified in various ways. For example, without connecting the end of the support part +Jr 5 t) to the formwork 20, as shown in FIG.
May be connected to 0. Branch 30 arm depth 75° 761 soil, - - Hole 25 of formwork 20 horizontal 7 runs 25.25 on the side
It has a protrusion 75a to be inserted into the hole 75a and 25a, and a hole 751++761 on the side of the pond. A pin 58 of a structure 56 is inserted into the holes 75b and 76b to connect the support member 5(). In addition. In FIG. 1, the parts 4 and 4 corresponding to the embodiment described in nII are designated by the same numbers 1 and 1, and detailed explanation thereof will be omitted.

As explained above, in the present invention, the formwork can be supported at a desired height and horizontally by opening the arm shrines provided on the supports vertically. Concrete foundations can be constructed accurately without performing precise ground leveling work.In addition, the (?4 precepts) of formwork support equipment are easy.
