Description

[Detailed Description of the Invention] The invention relates to an improvement of a concrete floor construction method.

The present invention was made in Patent Application No. 1A70g in 1930 (Japanese Patent Application No. 5T-TRQTSS) in 1932, and brought great benefits to the construction of concrete floors.
This is a further improvement of i.

Embodiments of the invention will be described with reference to the drawings.

In the figure, +11 is the formwork of the first embodiment, and the formwork (1

31 is formed.

Fold the connecting piece (6) down on one side parallel to the reinforcing lip (51) as shown in the figure. At the stop part, the end of the bottom surface (4) of the reinforcing lip is crushed using a press machine, and its tip (8) is superimposed on the back surface of the horizontal plate (2). Rear side (9) The slope starting from (
An inclined side (111) having the same inclination as 10+ is formed.In addition, in addition to forming the hooks at both ends of the formwork, as shown in Figure 6, if the formwork has a long overall length, It is also possible to form a concave part az approximately in the shape of a dome in the central part.As shown in Figures 8 and 6, it is placed and bridged to connect adjacent formworks. The piece (6) is fitted into the gap between the outermost reinforcing lip (5) and a number of formworks are laid, and if necessary, reinforcement is applied between the formwork and the steel beam (7) or the recessed part (121). The tip of the lip (51) where the end of the bottom surface (4) is crushed (the intermediate peaceful part a41 between 81 and (8) (or the intermediate flat part between reinforcing lips (5) and (5)) The required width @ [or d] and the required length Ll (or Sn) for the shoulder section (141)
A rectangular notch o9 (or notch window Q51)' is bored.

In Figure 3, (1) is the formwork of the second embodiment, with both 1 extending downward on the lower surface side of the approximately rectangular horizontal plate (2).

) is a notch, and both ends of the connection piece (61) are connected to the hook part (
f) and the slope (8') by cutting the joints into equal lengths. It is convenient to simply form the hooks at both ends of the formwork, but as shown in Figure 9', if the formwork has a long overall length, a concave part (1) of approximately the same shape as described above may be formed in the center. It is also possible to form

As shown in Figures 8 and 9, formwork (1 pith hanging part (7
) or recessed part (1dw), and place it directly on the top surface of the steel beam (support) and fix it by spot welding, etc., as necessary.

The formwork of the present invention is used to partially form a step (191).
Place the fully formed formwork (11?) on the horizontal plate (21) and crush it to make it horizontal with the horizontal plate (2), and pour concrete (Ln) on the top surface of the formwork. to form a floor slab with a flat surface.

It is necessary to crush the intermediate peace part al (or the intermediate flat part aj" between the reinforcing lip (5) and the bacterium) for crushing. As mentioned above, when constructing a concrete floor, Latch part (71
(Due to the presence of the notch (151 (151) or recess (121) or (9) cutout window (151 (151) drilled near 7i), between the formwork 1) The upper part and the lower part of the concrete are continuous, and 2
Latching part (71 (71 (straddle, concave part (121 or α0)
) The width of the notch (151 (151) was calculated in consideration of the width of the soil surface of the steel beam (5) to be installed.

The width of the cutout window a4 ai' shall be determined. For this purpose, the dimensions of the notch (151 (15j width width () DC) or 5 notch window (151 (151 @0 width) are as follows: 71 (q'+ o g vr + cn'r

) It is also possible for the p to become large.

In the present invention, as described above, the required number of reinforcing ribs (51+51... , are parallel to each other and bent, and at the apex of the triangular reinforcing lip (5), the tops of the both side walls (31 (31) contact each other to form a closed apex portion (131). In the concrete floor construction method that uses all of the formwork, the bottom edge of the reinforcing lip (5) was crushed with seven shakers, and the edge of the topmost surface (4) was crushed. Either make a full cutout α5) of the required width and length in the middle peaceful part between the tip and the top part, or connect both ends of the formwork +11 to the surface of the horizontal plate (2) and the reinforcing lip. (5) The intermediate peaceful part (141) of the notch a of the required width and required length between the bottom surface of the bottom surface and the part where the insides of both sides were crushed by pressing with a press machine from both sides. ; is used for concrete floor construction by drilling
Formwork (11<11+
Since the hanging part (71) is made of concrete that is placed horizontally on the beam, it is possible to significantly increase the reinforcement of the concrete floor and to improve the efficiency of concrete floor construction. It has the effect of λ.
