DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a panel mounting structure, and more particularly to a panel mounting structure for mounting a PC panel on a mounting base.

[0002]

2. Description of the Related Art In so-called crossover bridges crossing a strait, a sea route, etc., a suspension bridge structure capable of widening a span is often used. Anchorages that support the force play an important role as structural elements of the suspension bridge.

[0003] Such an anchorage is, as it were, a huge concrete block. In many cases, a PC (precast concrete) panel is used as a form for concrete casting.

[0004] The PC panel needs to be reduced in size to a predetermined size or less in order to prevent cracking due to a rise in temperature of the mass concrete for the convenience of manufacturing or transportation, and on the other hand, in the field, the use of a crane is required. It is desirable to be able to build in as few times as possible in terms of frequency or relation to other processes.

[0005] Therefore, in the PC panel mounting work, for example, a PC panel of about 3 m in width and about 1.5 m in height is once assembled on the ground, for example, as a set of four PCs via a predetermined assembling steel material. Generally, the panels are sequentially built at predetermined installation positions by a crane.

[0006] Hereinafter, the steel material for assembling the built large panel is connected to a mounting base provided at the installation position via predetermined bolts, and the large panel is fixed to the mounting base.

[0007]

Here, a predetermined hole is provided in each of the assembling steel material and the mounting base, and the above-mentioned bolts are inserted into these holes for fastening. If the installation accuracy is poor, the holes on the mounting base side will be displaced from the predetermined positions, and as a result, the large panel cannot be installed at the designed position.

In such a situation, in order to ensure the installation accuracy of the large panel, it is necessary to enlarge the hole of the mounting base or the steel material for assembling, or to newly drill another hole on the spot. Panel installation work was extremely time-consuming and complicated.

Further, since the conventional PC panel is mounted on the previously installed PC panel to support its own weight, it is impossible to secure a joint with the lower PC panel. , It cannot absorb the expansion due to the temperature rise of the mass concrete and the shear deformation at the time of the earthquake.
The panel could be damaged.

The present invention has been made in consideration of the above circumstances, and has as its object to provide a panel mounting structure that can easily mount a predetermined panel on a mounting base with high accuracy.

It is another object of the present invention to provide a panel mounting structure capable of securing a predetermined clearance between upper and lower panels.

[0012]

To achieve the above object, a panel mounting structure according to the present invention, as described in claim 1, connects a panel-side connecting member provided on the back surface of the panel via a predetermined connecting bolt. In a panel mounting structure configured to be connected to a mounting pedestal-side connecting member provided on a mounting gantry, the panel-side connecting member is provided with a groove-shaped opening through which the connecting bolt can be inserted and extending in a predetermined direction, and The gantry-side connecting member is provided with a groove-shaped opening through which the connecting bolt can be inserted and extending in a direction substantially perpendicular to the direction.

[0013] In the panel mounting structure of the present invention, the groove-shaped opening of claim 1 may be formed by substantially connecting two steel materials having a box-shaped cross section.
They are arranged in parallel and formed as spaces between the steel materials. Further, in the panel mounting structure of the present invention, the groove-shaped opening of claim 1 is formed as a space between the two channel steels by arranging the two channel steels substantially in parallel.

Further, the panel mounting structure of the present invention is described in claim 4.
As described above, a predetermined height adjustment mechanism is provided on at least one of the top part and the bottom part of the panel-side connecting member.

[0015]

In the panel mounting structure of the present invention, both the panel-side connecting member and the mounting base-side connecting member are provided with groove-shaped openings through which connecting bolts can be inserted, and the two groove-shaped openings are orthogonal to each other. Therefore, when the panel is erected near the mounting base, a space is formed through the panel-side connecting member and the mounting base-side connecting member at a position where the two groove-shaped openings intersect.

When the panel is fixed to the mounting base, a connecting bolt may be inserted into the space, and then the inserted connecting bolt may be fixed to the panel-side connecting member and the mounting base-side connecting member, respectively.

In this configuration, even if there is an error in the installation accuracy of the mounting base, the above-mentioned intersection must be formed at the intersection of the groove-shaped opening of the panel-side connecting member and the groove-shaped opening of the mounting base-side connecting member. A space is formed, and a space for inserting the connecting bolt is always secured.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the panel mounting structure of the present invention will be described below with reference to the accompanying drawings.

FIG. 1A shows a panel mounting structure according to the present embodiment in a vertical section, and FIG.
(a) is a horizontal cross-section along the line AA.

As can be seen from these figures, the panel mounting structure of the present embodiment is such that a large panel 1 is mounted on a mounting base 2, and the large panel 1 is a PC (precast concrete) panel 3 as a panel. (For example, about 3 m in width and 1.5 m in height) are assembled on the ground in advance, and the mounting base 2 is installed at a predetermined concrete casting position.

FIG. 2 is a rear view of the entire large panel 1 as viewed from the right side of FIG.

As can be clearly understood from FIGS. 1 and 2, the large panel 1 is provided with bolts 4 provided on the back of the PC panel 3.
Are fastened to steel members 5 arranged at predetermined intervals in the horizontal direction, whereby four PC panels 3 are integrally assembled.

A panel-side connecting member is formed on the back surface of the steel material 5 by vertically arranging two sets of channel steels 6 at predetermined intervals at a predetermined interval. Is formed with a groove-shaped opening 7 extending in the vertical direction.

FIG. 3 is a rear view of the mounting base 2 as viewed from the right side of FIG. In addition, the mounting base 2 is configured as a part of the truss structure, and FIG. 3 partially shows a range equivalent to the large panel 3.

As can be clearly seen from FIGS. 1 and 3, on the front surface of the truss member 12 of the mounting base 2, two sets of channel steels 11 are horizontally arranged at a predetermined interval as a set of two channel steels 11. A side connecting member is formed, and a groove-like opening 13 extending in the horizontal direction is formed between the channel steels 11.

In the panel mounting structure of this embodiment, the connecting bolt 21 is inserted into the groove-shaped opening 7 formed between the channel steel members 6 and fastened with the washer 22 and the nut 23. The large-sized panel 1 is connected to the mounting base 2 via the connection bolts 21 by inserting the above-described connection bolts 21 into the groove-shaped openings 13 formed therein and fastening them with the washers 24 and the nuts 25. .

The washer 22 is of a size capable of firmly sandwiching the two channel steels 6 from both sides. Similarly, the washer 24 is of a size capable of firmly sandwiching the two channel steels 11 from both sides. It is better to use one.

As can be seen from FIG. 1, a height adjusting mechanism 31 is provided at the top of the channel steel 6 which is a panel-side connecting member.

In the height adjusting mechanism 31, the nut 32 is double-fitted on the bolt 33 and screwed into the top of the channel steel 6. The head of the bolt 33 supports the large panel 1 on the upper side. The depth can be adjusted.

In the panel mounting structure of this embodiment, the groove-shaped opening 7 through which the connecting bolt 21 can be inserted into both the channel steel 6 as the panel-side connecting member and the channel steel 11 as the mounting base-side connecting member. A groove-shaped opening 13 is provided, and the two groove-shaped openings 7 and 13 are orthogonal to each other.

Therefore, when the large panel 1 is built near the mounting base 2, a space where the connecting bolts can penetrate is formed at the intersection of the two groove-shaped openings 7, 13 when viewed from the rear. You.

The connecting bolt 21 is inserted into the space,
Next, the inserted connecting bolt 21 is fixed to the channel steel 6 and the channel steel 11 using washers 22, 24 and nuts 23, 25, respectively, and the large panel 1 is attached to the mounting base 2.

FIGS. 4A and 4B are rear views of the large panel 1 and the mounting frame 2 when the large panel 1 is mounted on the mounting frame 2 using the connecting bolts 21. FIG. .

Here, even if there is an error in the installation accuracy of the mounting base 2, the above-mentioned space is always formed at the intersection of the groove-shaped opening 7 and the groove-shaped opening 13, and the connecting bolt 21 is inserted therethrough. Space is always reserved.

FIG. 5A shows the mounting position of the connecting bolt 21 when the channel steel 11 of the mounting base 2 is installed at the designed position. FIG. 5B shows the mounting position of the connecting bolt 21. Channel steel 11
Indicates the mounting position of the connecting bolt 21 when it is set to be shifted downward by L1 and rightward by L2 from the design position as indicated by an arrow.

As can be seen from the figure, the mounting position of the connecting bolt 21 is shifted downward from the normal position by L1 in relation to the channel steel 6, and is shifted to the normal position in relation to the channel steel 11. Is shifted to the left from the position by L2.

The adjustment of the panel installation position along the normal direction of the PC panel (the left-right direction in FIG. 1) is performed by connecting bolts 2
The position of the nut 23 or the nut 25 with respect to 1 may be appropriately adjusted.

FIG. 6 is a vertical cross-sectional view showing a state in which two large panels are arranged vertically and attached to the mounting base 2. In addition, for the components related to the upper large panel, a
, And parts related to the lower large panel are distinguished by adding b.

As shown in the figure, when the large panel 1a and the large panel 1b are arranged up and down, both large panels are attached to the mounting base 2 as described above, and when the large panel 1a is erected, the grooves are formed. The bottom of the steel 6a is placed on the height adjusting mechanism 31b provided on the top of the large panel 1b that has been built in advance, and the weight is transmitted to the large panel 1b below via the height adjusting mechanism 31b.

Here, a predetermined clearance d is formed between the PC panel 3a and the PC panel 3b by appropriately adjusting the height adjusting mechanism 31b, and a predetermined joint width is secured if necessary.

After the installation of the large-sized panels has been completed for a predetermined number of steps, concrete placement is sequentially performed.

As described above, in the panel mounting structure of the present embodiment, the groove-shaped openings through which the connecting bolts can be inserted are arranged orthogonal to each other in both the panel-side connecting member and the mounting base-side connecting member. Even if the installation accuracy of the mounting base is poor, a space where the connecting bolt can always penetrate is formed at the place where the two groove-shaped openings intersect.

Therefore, regardless of the accuracy of the mounting base,
The large panel and the mounting base can be securely and easily attached to each other, and it is not necessary to provide a new hole as in the related art.

Accordingly, the construction period of the large panel installation work is shortened and the construction cost is reduced.

Further, in the panel mounting structure of the present embodiment, since the groove-shaped opening is formed by using two channel steels having substantially the same dimensions and the connecting bolt is inserted, the channel steel is formed by the two washers. Can be transmitted evenly to the two channel steels when sandwiching and tightening from both sides.

In the panel mounting structure of this embodiment, the height adjustment mechanism is provided on the panel-side connecting member, so that the upper and lower PCs are connected.
A predetermined clearance can be formed between the panels to secure a space for providing joints.

Therefore, when installing a large panel, it is possible to secure a predetermined panel installation accuracy by absorbing a manufacturing error or an assembly error of the PC panel, and to reduce the temperature of the internal concrete after the concrete is poured. It is possible to prevent the PC panel from cracking by absorbing the accompanying expansion and to prevent the panel from being damaged by the earthquake by absorbing the shear deformation at the time of the earthquake.

In this embodiment, the PC panel is assembled into a large panel in advance, and this is mounted on the mounting base. However, a panel-side connecting member is provided for each PC panel, and these are individually mounted on the mounting base. You may make it attach to.

Although the present embodiment has been described with reference to an example using a PC panel, the present invention can be applied to a case where a panel made of another material such as a steel panel is used.

Further, in this embodiment, the groove-shaped opening for inserting the connecting bolt is formed by arranging two channel steels substantially in parallel, but the structure for forming the groove-shaped opening is optional. Yes, for example, steel materials having a box-shaped cross section may be arranged side by side.

[0051]

As described above, according to the panel mounting structure of the present invention, a predetermined panel can be mounted on the mounting frame with high accuracy even if the mounting accuracy of the mounting frame is poor.
