Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a wall balustrade mounting structure, and more particularly to a structure for attaching a precast reinforced concrete wall balustrade to a floor plate provided with anchor means such as anchor bolts.

[0002]

[Problems to be Solved by Prior Art and Invention]

 Conventionally, for structures such as bridges, a wall balustrade made of precast reinforced concrete or the like is integrally attached to the floor plate on which anchor means such as anchor bolts are arranged so that safety of vehicles passing over the floor plate can be secured. Is configured.

By the way, as a mounting structure of a floor plate and a wall balustrade in such a structure as a bridge, for example, an anchor bolt 3 preliminarily embedded in the floor plate 1 is integrally manufactured with a wall balustrade 5. The structure in which the fixed anchor frame 7 is mounted and fixed by the bolt 9 (see FIG. 3), or the PC steel rod 11 arranged on the floor plate 1 is inserted through the insertion hole 13 provided in the wall rail 5, and then the bolt is inserted. A structure (see Fig. 4), etc., is adopted in which it is fixed and integrated by being tense at 9 points.

However, in the former structure in which the anchor bolt and the anchor frame are combined, if the number of anchors is increased in order to reduce the size of the material, the position of the anchor bolt and the anchor frame will not match, while load distribution will be possible. There were many cases and the work was often complicated. Therefore, the number of anchors tends to decrease in recent years, but if the number of anchors is reduced like this, the stress acting on one place increases, and not only the anchor bolts and bolts become larger, but also the anchor frame and this There was a problem that economic efficiency deteriorated because reinforcement around the frame was also necessary.

On the other hand, the latter applies tension to the PC steel rod and integrates the floorboard and the wall balustrade, so that not only a special tension work is required, but also a mismatch between the PC steel rod and its insertion hole is prevented. In order to do this, it is necessary not only to devise measures such as setting the length of the wall balustrade to about 2 m, but there is also the problem that the installation work is complicated and takes a long time.

[0006]

[Means for Solving the Problems]

 Therefore, in the present invention, in the structure in which the reinforced concrete wall balustrade is attached to the floor plate on which the anchor means is arranged, the bottom of the reinforced concrete wall balustrade has an open bottom, for example, a void portion set to a pull-out resistance shape such as a tapered shape. An anchor means such as an anchor bolt protruding from the floor plate is housed in this space, and the space is filled with non-shrinkable mortar to integrate the floor plate and the wall balustrade. Thus, it is intended to facilitate the work of attaching the floor plate and the wall balustrade and to obtain a structure for attaching the floor plate and the wall balustrade that has sufficient strength.

Further, in this case, if anchor bolts and the like on the main body of the wall balustrade are projected in the void provided in the wall balustrade, the floor plate and the wall balustrade of the non-shrinkable mortar filled in the void are provided. This is preferable because the integration can be performed more reliably.

[0008]

[Work]

 In the mounting structure of the wall balustrade according to the present invention, the floor plate and the wall balustrade are integrated by fixing and holding anchor means such as anchor bolts protruding from the floor plate by hardening the non-shrinkable mortar filled in the void. To do.

[0009]

【Example】

 A preferred embodiment of a wall balustrade mounting structure according to the present invention will now be described in detail with reference to the accompanying drawings.

Referring to FIG. 1, a wall balustrade mounting structure according to the present invention is provided with a void portion 24 of a predetermined shape in a bottom portion 22 of a wall balustrade 20 made of precast rebar concrete. The floor plate 26 and the wall balustrade 20 are integrated by accommodating the embedded anchoring means 28 and filling the void portion 24 with the non-shrinkable high-strength mortar 30.

That is, the bottom portion 22 of the precast reinforced concrete wall balustrade 20 has, for example, a void portion 24 whose cross-sectional shape serves as pulling resistance by embedding a winding pipe 32 having a diameter of about 280 to 300 mm. The anchor bolt 34 on the wall balustrade main body 20a side is projected in the space 24.

In addition, it is preferable that the anchor bolt 34 is wound with a spiral streak 36 as in the present embodiment, and further, the cross-sectional shape of the void portion 24 is reverse tapered so as to oppose pull-out resistance. If it is configured as a shape, it is possible to omit the embedding of the winding pipe.

Positioning bolts 38 used for setting a clearance when the wall balustrade 20 is installed on the floor board 26 are provided at four corners of the bottom 22 of the precast reinforced concrete wall balustrade 20.

On the other hand, the anchor means 28 embedded in the floor plate 26 winds the spiral streaks 36 around the anchor bolts 40, 40 arranged at a predetermined distance, and supports the anchor bolts 40, 40 between them. Although it is configured by connecting via a pressure plate 42, when the anchor means 28 is housed in the void portion 24 of the wall balustrade 20, the anchor bolt 34 is protruded from the balustrade main body 20a side and is offset by approximately 90 degrees. Place it in the specified position.

Next, the procedure of the work for attaching the wall balustrade 20 to the floor plate 26 and integrating them will be described. First, the anchor means 28 of the floor plate 26 is housed in the void portion 24 at the bottom of the wall balustrade 20. Is installed at a predetermined position on the floor plate 26. At this time, the blind nut 44 is attached to the positioning bolt 38 at the bottom of the wall balustrade 20 and the adjustment is properly performed, so that the reference plane B of the floor plate 26 and the wall can be adjusted. It is set so that a gap of, for example, about 30 mm is formed with the bottom surface of the balustrade 20.

Then, the outside of the gap between the reference surface B of the floor plate 26 and the bottom surface of the wall balustrade 20 is closed using an appropriate closing means such as an adhesive tape to leave a part of the gap, and the wall balustrade 20 is opened through the opening of the gap. The non-shrinkable high-strength mortar 30 is filled in the void 24 by a mortar injection hose inserted in the void 24, and is cured, and after the mortar is cured, the closing means may be removed.

[0017]

[Effect of the device]

 As described above, according to the wall balustrade mounting structure of the present invention, it is possible to easily perform alignment (hole matching) between the anchor means projecting from the floor plate and the void portion at the bottom of the balustrade, so that the anchor pitch can be reduced. It is possible to cope with long wall balustrade, and the integration work can be performed very easily.

Further, since the floorboard and the wall balustrade are integrated by the non-shrinkable high-strength mortar filled in the voids, stress is not concentrated only on some anchor bolts, so that the anchor means can be downsized. Therefore, it is not necessary to reinforce a large anchor frame and the surroundings of the fixing part as in the past, and special work such as PC work can be omitted, so that the installation work is easy and the strength of the floor plate and wall balustrade is sufficient. It has various advantages, such as the ability to obtain a mounting structure for, and its practical effect is extremely large.

The preferred embodiment of the wall balustrade mounting structure according to the present invention has been described above. However, the present invention is not limited to this embodiment, and the wall balustrade may be provided, for example, in a void portion of the wall balustrade. It goes without saying that various modifications can be made without departing from the spirit of the present invention, such as omitting the anchor bolts and facilitating the mounting work.
