Abstract

PURPOSE: To enable it to construct a lightweight and economical parking lot's drop preventing wall without using any scaffold by setting up a reinforcing bar and a form on the inside of a prestressed concrete panel secured to a girder as an outer wall and placing concrete thereinto. CONSTITUTION: A prestressed concrete panel 3 is secured tight to a pair of brackets 2 and 2 clamped to a girder 1 so as to cover a lower part of this girder 1 by means of clamping means (bolt and nut) 4. Next, a reinforcing bar 5 is set up in a spot where concrete is placed after being connected to a projecting end 6a of another reinforcing bar 6 of the PC panel 3, and further, a deck plate 8 is laid down in accord with a top face of the girder 1, and the concrete is placed, thereby constructing a floor 7. After floor concrete is hardened, the projecting end 17 of the reinforcing bar 16 of the PC panel is connected to the reinforcing bar 5, and then a form 13 is set up on the inside of the PC panel 3 via a separator 13, and concrete is placed in space between another form 11 and the PC panel 3. In this connection, the PC panel 3 is left behind intact as an outer wall.

However, the construction of the conventional fall prevention wall as described above has the following drawbacks. In constructing the fall prevention wall 21, a scaffold for installing the formwork has to be assembled outside the building, which increases the number of work steps. A concrete pouring seam 24 remains on the boundary of the fall prevention wall 21 of the floor 20, and the treatment is required thereafter. A large amount of concrete is required to construct the sag wall 22, which causes a cost increase. The load of the sag wall 22 is applied to the girder 23, and the girder 23 needs to be enlarged. In view of such a point, the present invention is to provide a fall prevention wall construction method for a multi-storey parking lot that solves the above-mentioned conventional drawbacks.

In order to solve the above problems, the present invention provides a precast concrete panel erected on the girder so that the girder is covered from the outside by a lower part of the precast concrete panel, and the precast concrete panel is molded. It is characterized by constructing a fall prevention wall by placing concrete as a frame.

According to the present invention, since the precast concrete panel erected on the girder is used as a formwork when constructing the fall prevention wall, it is not necessary to install a scaffold outside the building and the concrete pouring is performed. There is no need to remove the formwork after installation. Also, the concrete pour seams are covered with precast concrete panels, eliminating the need for post-treatment.

Embodiments of the present invention will be described below with reference to the drawings. First, as shown in FIG. 1, a precast concrete panel (hereinafter referred to as a PC panel) 3 is vertically fixed to a pair of upper and lower brackets 2 and 2 fixed to a girder 1 by using a fixing means 4.

As the fixing means 4, conventionally known means can be adopted. For example, screw connection with a bolt and a nut can be mentioned. At this time, it is desirable that the brackets 2 and 2 be provided with slots in the vertical direction so that the mounting position of the PC panel 3 can be adjusted. Also, the bracket 2,
The mounting direction of the bolts and nuts on the PC panel 3 is not limited to the direction orthogonal to the PC panel 3 as shown in FIG.
Also, by fixing a bracket (not shown),
You may make it screw in a parallel direction. Since the PC panel 3 is not only located on the outer surface of the fall prevention wall but also serves as the outer wall of the structure, the girder 1 can be attached to the PC panel 3, that is, the girder 1 is below the PC panel 3 from the outside. Cover and install at the top as the height of the fall prevention wall to be built.

Next, the reinforcing bars 5 are arranged at the places where concrete should be poured. At this time, the protruding end 6a of the PC panel 3 on the rear surface side of the reinforcing bar 6 is connected to the arranged reinforcing bar 5. When the work of arranging is completed, concrete is poured to construct the floor 7. Reference numeral 8 in the figure denotes a deck plate that receives concrete at that time.

After the concrete forming the floor 7 is solidified, as shown in FIG. 2, the form 11 is installed inside the PC panel 3 with a constant space. This interval is set to the thickness of the fall prevention wall to be built. Also, this formwork 1
1 is installed using a conventionally known means. An example thereof is shown in FIGS. 2 and 3. FIG. 2 shows an example in which the separator 13 is interposed between the mold 11 and the insert 12 for the separator, which is embedded in the PC panel 3 in advance, and fixed by the wing nut 14. FIG. It is an example in which the tubular body 18 arranged by the foam tie 15 instead of 14 is fastened and fixed. There is also a method of attaching with a foam washer using a pad washer. The arranged reinforcing bar 5 is located between the mold 11 and the PC panel 3 thus installed.

Next, concrete is placed between the formwork 11 and the PC panel 3 to construct the fall prevention wall 9. FIG. 4 shows an enlarged view of this state. By the way, the PC panel 3 is provided with a reinforcing bar 16 as shown in FIGS. The method of arranging the reinforcing bar 16 is not particularly limited, but a part of the reinforcing bar 16 is provided with the protrusion 17 on the back surface. For example, the lower end muscle 16a, the lattice muscle 16b, the top muscle 16c, and the like are formed, and the protrusion 17 is formed by the lattice muscle 16b and the top muscle 16c. This reinforcement 16
May be connected to the reinforcing bar 5 at the protruding portion 17. Therefore, when the concrete is poured, as shown in FIG. 4, the projecting portions 17 of the reinforcing bars 16 are embedded in the poured concrete and integrated. Then, when the poured concrete is solidified, the mold 11 is removed to form the fall prevention wall. FIG. 1 shows the completed fall prevention wall as a whole, and FIG. 5 shows an enlarged part thereof.

However, the mold located on the outer surface side is a PC
Since the panel 3 is used, it can be attached and fixed to the girder 1 by the fixing means 4. Therefore, it is not necessary to build a scaffold and the mounting is easy, so that the workability is remarkably improved and it is economically advantageous. In addition, since the PC panel 3 is left as an outer wall after the concrete is placed, it is not necessary to remove it. Furthermore, since the PC panel 3 serves as an outer wall, the multi-story parking lot can be beautifully laid out without applying subsequent makeup.

As described above in detail, according to the present invention, the following effects can be obtained. Since the PC panel can be used as a formwork when building a fall prevention wall, there is no need to install a scaffold outside the building,
Work man-hours are reduced. The concrete seams that occur at the boundary between the floor and the fall prevention wall are covered by the PC panel, eliminating the need for post-treatment. Since the sauce wall is composed of PC panels, the amount of concrete placed is small and economical. The weight of the sag wall is reduced, and the girder can be downsized.
