Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a formwork assembly method for pouring concrete.

In conventional formwork construction methods of this type, panel formwork is first assembled by connecting them to each other, and then end pieces are attached to reinforce such formwork, but according to this method, The formwork must be connected together, which is not only cumbersome and time-consuming, but the accuracy of the formwork connection affects the overall accuracy, and therefore the process and
The drawback is that construction management must be strictly controlled, resulting in extremely high construction costs. The present invention solves these conventional drawbacks, and enables simple work with high accuracy.
This was done with the aim of providing a new formwork assembly method that can be carried out at low cost.

Hereinafter, the construction method of the present invention will be explained based on an illustrated embodiment. As shown in FIG.
(1)-1, is the support, and these corner thickets (1)<
1), ,, a predetermined number of horizontal thickets (2) (2) ,,
, and connect horizontal and vertical tongue buckle type places (3) (3) between each corner to form a frame type frame (4). As shown in FIG. 4, a bolt (5) is provided protruding from the lower end of each corner end (1), and level adjustment is performed by adjusting this bolt (5). Figure 2 shows an example of how to connect these end pieces (1), (2) and the place (3). A U-shaped connecting fitting (6) facing outward is fixed, and this connecting fitting (6)
A pin hole (force (7)) is formed in each of the upper and lower pieces.

On the other hand, the horizontal end (2) has a pin hole (7) at its end.
) A pin hole (8) corresponding to (7) is formed, and this end is inserted between the upper and lower pieces of the U-shaped connecting fitting (6),
'' Insert the pin (9) from above into each of the pin holes (7) and (8) to connect the horizontal end (2). Furthermore, at the upper and lower ends of the corner thicket (1), L-shaped connecting fittings (
10) is fixed, and the connecting hole (
11) to connect place (3). In addition,
Instead of such a tongue buckle type place (:3),
A square moon-shaped place may be installed between the horizontal end pieces (1) (1) of each corner. =F, l'r, this does not preclude the installation of all the vertical end pieces in the middle between each corner end piece (1) (1).

Now, after forming the frame (4) as described above, an inner formwork (12) is placed on the outside of this frame (4) as shown in Fig. 3.
Install the fire. Figure 5 shows how to install these inner formworks (12). First, the horizontal end (2) has a number of connections penetrating inside and outside at predetermined intervals in the longitudinal direction. A hole (13) is formed, and correspondingly, a connecting hole (14) is also formed in the inner formwork (12), and these connecting holes (13×14.) are adapted to each other to The formwork (12) is brought into contact with the outer surface of the horizontal edge (2). (15
) is a separator having a male thread (16) formed at its end; (17) is a form tie having a female thread (18) formed at one end; 12) into the connection holes (13) and (14) from the outside, and insert the female screw (18) side end of the form tie (17) into the connection hole (13) from the inside of the horizontal end (2). The female screw (18) is screwed into the male screw (16) of the separator (15) and tightened. (19) is a washer inserted into the other end of the form tie (17), and (20) is a bolt-shaped head similarly provided at the inner end of the form tie (17).

After installing the inner formwork (12) as described above, the sixth
As shown in the figure and FIG. 7, attach the outer formwork (21).

Figure 7 shows how to install it, and the outer end of the separator (15) is connected to the connecting hole (21) of the outer formwork (21).
2), and screw the U-shaped hardware (23) from the outside to fix the outer formwork (21). (24) is this U-shaped hardware (23)--, the fitted outer horizontal edge,
Historically, a wedge-shaped fixture (25) is driven into the upper and lower pieces of the U-shaped hardware (23) on the outside of the horizontal end piece (24), thereby fixing the horizontal end piece (24). Ru.

In addition, in Fig. 6, (26) is the inner and outer formwork ((3
).

12) (21) Satsushi-1 (27) (2)
7) is this satsushi (26) and each formwork (]-2) (2
1) is an inner and outer support frame that holds the sash (26). In addition, as shown in Figure 6, the skeleton (
4) A horizontal end piece (2) separate from the frame (4) is attached to the inside of the inner formwork (12) that protrudes upward. Figure 7 shows the state of concrete (30) being placed.

Finally, as shown in FIGS. 7 and 8, a slab river bed (28) is constructed on the horizontal end (2) of the inner step, and a slab panel (29) is laid on its upper surface.

According to the present invention as described above, unlike the conventional construction method in which the formwork is first connected to each other and then reinforced with shafts, there is no need to connect the formworks together, and moreover, even the inner shafts can be raised accurately. Once this is done, all that is left to do is to attach the formwork using the connection holes made in the inner edge, and a highly accurate product can be obtained.Therefore, there is no need for detailed process control like in the past. , which has the effect of being able to be constructed in a short period of time at low cost. In addition, in conventional assembly methods, if dust or other debris adheres to the connecting end of each formwork, this will affect accuracy and require early replacement, but with the present invention, such debris can be removed in advance. Anticipate other adhesion and concre between each formwork! J
If -1- is installed with enough room to prevent leakage, it can be used repeatedly over a long period of time, which is advantageous in terms of monthly interest costs.
