Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a support device for supporting a rising part formwork of a cloth foundation from below.

For fabric foundations, the one-piece construction method is becoming more common due to its shortened construction period and increased foundation strength.An example of this construction method is shown in Figure 8. The pace part formwork (2) (2) and the upright part formwork (3) (3) are arranged above. At this time, the formwork support device (
4). The formwork support device (4) has a pace part formwork (
2) (2) is often propped up. In addition, in order to maintain the interval between the rising part formwork (3) (3) at a predetermined width, space holders (5) are required above and below the rising part formwork (3) (3).
) is used.

In order to support the rising part formwork (3) <3) from below, conventional concrete blocks and the like have been used.

However, concrete blocks cannot be manufactured in a short time, are expensive, and are difficult to transport due to their high weight, making them difficult to handle during construction on site. However, problems were being raised in terms of price and handling.

Therefore, we have conducted various studies on the possibility of manufacturing something with the same functionality as a concrete block by pressing steel plates, and have made proposals so far and have provided some products to the world. This method of pressing steel plates can be manufactured in large numbers in a short time, is inexpensive, and - the weight per piece is about 1/1 that of concrete blocks.
It is lightweight (0~1/20) and (a) many pieces can be stacked on top of each other, so even if the warehouse area is small, it is possible to store many pieces and transport many pieces at once. In addition, it is extremely easy to handle when used on cloth foundations because it is lightweight, and after the concrete has hardened, this support device can be used as a reinforcing material in the same way as reinforcing bars. It was.

In addition, the formwork support device, which was formed by pressing a single steel plate into a nearly concave shape, also had a sharp press cut surface facing inward in the longitudinal direction, which could cause injury when handled. On both sides of the pace part, as shown in Figure 8, there is a bevel. - In the case of the cloth foundation construction method in which reinforcing steel bars (6) (6) are arranged, there are drawbacks such as the fact that this may not be possible depending on the dimensions.

Therefore, in the present invention, each member of the formwork support device is made of a combination of flat steel plates and metal bars, although they are not made of metal, which is an unprecedented structure. The grounding member and the support member are rotatably attached to the grounding member. By adopting a cylindrical structure, it solves the disadvantages of concrete blocks and has all the advantages of round steel plate support devices.
Moreover, the above-mentioned problems of the steel plate support device have been solved.

This will be explained in detail below with reference to the drawings.

The drawings are illustrative of the present invention, and include Figures 1Ii1 (a) to 4.
Figures 1(b) and 2(b) and 5(b) are perspective views of the formwork support device with the supporting members folded down.
a) and FIG. 6C&) are perspective views of the support member. FIG. 5(b) is a perspective view of the support member connection part, and FIG. 5(C)
FIG. 2 is a partial plan view of a flat steel plate showing a press cutting state of a support member. FIGS. 6(b) and 6(e) are perspective views of the rotating shaft portion of the support member. FIG. 8 is a front view showing the usage letter. FIG. 9 is a plan view showing the peripheral shape of the support member 1# constant' notch.

The formwork support device (4) of the present invention consists of a metal grounding member ω and a support member (2). As shown in FIG. 8, the grounding member is usually the part that contacts the rock (1) when the device is placed on the rock (1), and is preferably elongated. In the illustrated diagram, the grounding member (2) is entirely made of a steel plate, but it may also be formed into a rectangular shape by bending a round metal bar. Additionally, a lip may be provided on the flat steel plate for reinforcement. Characteristics of the grounding member
9) is provided. This support leg (9)
(9) is provided by cutting and raising the inside of the plate-shaped grounding member (2) in the examples shown in FIGS. 1 to 4. Well, in the example of @7WJ, both ends of the grounding member (2) are bent. Forming the support legs (9) (9) by cutting and bending them in this way is simple and desirable in manufacturing, but it is also possible to prepare the support legs as separate parts and weld them using spot welding or the like. It is also possible to provide one. The support leg (9) of the grounding member (7) is provided with a rotation hole (b) into which a rotation shaft 01 of the support member (2), which will be described later, is fitted.

On the other hand, there is a support member (8), and a formwork mounting part (2) on the left and right sides of the top surface.
(2), and in the middle of the support member (2), a rebar arrangement support part (to) which is lower than the formwork mounting part (2) is formed in a concave shape. 2) Formwork placement part (2)
) (b) is provided with an upright portion α◆ rounded to support its horizontal portion from the bottom. Below this upright portion α◆, a rotation shaft portion 00 is provided horizontally in the support leg portion (9) of the above-mentioned grounding member ψ and inserted into the rotation hole Ql, resulting in a nine structure.

Although the structure shown in Fig. 1 consists of the grounding member ψ and the support member ■, the relatively long support legs (9) are folded and the support members are folded down. When not in use, especially when being stored or loaded, it can be kept folded like this.
It is convenient because the warehouse area is small and many items can be transported at once. (a) tlj: In its folded state, step on the grounding member ψ,
When you put your hand on the support member (2) and raise it up, the support legs (9) stand up as the support member (2) rotates, and when the rotation is approximately 90@, the support member (2) stands upright,
It has a structure in which the upright part IJ4 is fitted into and fixed to a support member fixing notch provided at the upper part of the support leg part (9). In this example, since the support leg (9) is forcibly made to stand up, the support leg (9) does not run over and exerts an inward spring force. Therefore, the support member (8) is held in an upright position safely and reliably. This is because the supporting legs (9) have elasticity. In this example, the support member (2) is obtained by molding a single rod.

On the other hand, as shown in Fig. 2, when the support legs (9) are short and do not have elasticity, when the cane and support member (8) are raised, the support member (2) rotates. Enter the shaft part (11) side or inward, and insert the upright part a into the support member fixing notch (G).
→ will fit and be fixed in an upright position. In this case, Hiro 2nd
The upright portion will exert a spring force outward as shown in Figure (b). This shape also supports the supporting legs (9) in a resilient state.
Since the upright portion of the support member (2) has a width σ, the upright state of the support member (2) is firmly maintained. In the example shown in Fig. 2, both sides of the support member (8) are honed and the protruding ends σ
Q time is formed. The upright part α4 of the tab is attached to the formwork mounting part (
6) It is attached to the lower part of the middle part and has a nine-piece structure. With such a structure, the distance between the two upright formworks placed on the main part can be wide or narrow. 2) Can be used to hang the top edge. Further, it has various advantages such as being able to arrange the base reinforcing bars (6) (6) at the lower part of the protruding end Oφ.

In the previous examples, the elasticity of the support leg part <9) of the grounding member (2) or the upright part (B) of the support member (2) contributes to keeping the support member (2) upright safely and reliably. Yes, but the third
As shown in the figure, on both sides of the notch (to) at the upper end of the support leg, an already bent bent end αη and a bendable end (to) that is easy to bend are provided.゛Support member (2)
It is a good structure to reliably maintain the erected state by rotating the osm to stand up and then bending the bendable end osm.

First, in the notch provided in the upper part of the support leg main body, bendable ends (to) (to) are formed on both sides of the notch (to), and a support member abutting piece 09 is further cut and raised at the bottom thereof. The example shown in FIG. 4 is provided. As in the example shown in FIG. 3, the bendable end (end) is preferably made thinner at the base or provided with grooves, cutting lines, etc. to make it easier to bend by hand. In the example of Fig. 4, a support piece for supporting the reinforcement support part (to) of the support member (2) by cutting and raising the grounding member ψ so as to withstand the weight of the upright part formwork. has been established. This supporting piece) can be optionally provided in other examples as well when the supporting member (2) is thin and weak.

In the examples so far, the support members (!) are all metal round bars, but in addition to the tip bars, square bars, flat bars, and hollow tubes of these can also be used. In addition, as shown in FIG. 5 (1), a round bar is used for the upright portion 04, and the formwork mounting portion (
2) As shown in (C), spot weld the upright part α4Q4 to the lower part of (6) and the reinforcement support part (b) using a plate material punched out from a flat steel plate using a press. Alternatively, as shown in (b), a mounting hole may be formed by cutting out the formwork mounting portion (6), and the upright portion ◆ may be press-fitted into this or inserted and then fixed by caulking.

On the contrary, in Fig. 6 O), the formwork mounting part (b) (2) and the reinforcement support part (to) are formed with round bars, and the upright part Q4H angle-shaped plate' material is used. 9 shows an example in which a short round bar is welded to the rotating shaft part 0000. The rotation shaft member α0 is a support member (2)
It is only necessary to have a joint to rotate when raising the upright part from the horizontal direction to the vertical direction, so the lower end of the upright part α 3)
A narrow piece may be welded to the lower end of the upright portion a◆ as shown in . Even a rotating shaft portion having such a shape is sufficiently useful for rotating the support member.

' In the examples shown in Figs. 1 to 4, the support legs (9) are formed by cutting and raising the grounding member (7) inwardly. When the support leg portions are formed by cutting and raising them laterally, the support leg portions on both sides are formed more inwardly than those illustrated so far. When a support member as shown in FIG. 2 or FIG. 5(a) is attached to such a support leg,
The base reinforcing bars (6) (6) described in the explanation of FIG. 21 can be arranged on both sides.

In addition, according to the preferable shape of the periphery of the support member fixing notch Ql as shown in FIG. This shows an example in which a sliding guide part @ is provided.

In other words, as in the examples shown in FIGS. 1 and 2, the supporting legs (
9) Or, when the upright part α◆ is rotated and raised in the case where it is elastically supported by the support member (8), the upright part a◆ slides on the end face of the support leg part (9) and rises. However, if the side end surface of the color support member fixing notch Ql is a right-angled shape, the right-angled part becomes the stopper and the upright part α◆ becomes the support member fixation notch). It's not easy. therefore,
As shown in FIGS. 9(a) and 9(b), this can be achieved by providing a sliding guide part @ in which one or both end surfaces of the support member fixing notch (to) are inclined with respect to the end surface of the support leg (9). , upright part α◆
This allows for smooth sliding and fitting into the support member fixing notch.

Since the present invention has the structure as described in detail above, - a large number of units can be manufactured in a short time, and it is inexpensive and lightweight.

Since it has a folding structure, it can be stacked and stacked. Therefore, the warehouse area required for storage is small, and many items can be loaded at once during transportation, reducing transportation costs. When it is used, it can be assembled with one touch, which saves construction labor and time. It has a safe structure even though it is made of metal. It can be applied to any wide or narrow gap between the vertical formworks, and any reinforcement arrangement is possible, making it widely applicable to the diversification of foundations and cloth foundations. Furthermore, it has many advantages, such as acting as a reinforcing material after the foundation concrete hardens.
