Description

[Detailed explanation of the idea] [Industrial application field] The present invention relates to a mounting structure for building members.

[Conventional technology]

When attaching this type of construction member to a mounting bracket that is fixed to the ground, a lip engagement groove is formed in the member, and a fixing bolt with a substantially rectangular head is inserted through the elongated hole in the bracket. into the lip engagement groove, then rotate the bolt around its axis so that the long axis of the bolt head is perpendicular to the longitudinal direction of the lip engagement groove, and then screw the nut onto the leg of the bolt. It is conventionally known to engage the head of the bolt in the lip by pulling the bolt toward the bracket.

In this type of structure, the lip constituting the lip engaging groove is in direct contact with the bracket,
A shallow groove according to the present invention, which will be described in detail later, is not formed.

[Problem that the invention attempts to solve]

However, when installing architectural components,
It is often necessary to adjust the mounting position on site. For this purpose, the bracket is usually provided with a long hole for the bolt to pass through. When forming this elongated hole, if you form an elongated hole with a width larger than the long axis length of the bolt head, the long axis direction of the bolt head can be aligned with the longitudinal direction of the opening of the lip engagement groove, and the lip can be removed as is. A bolt head can be inserted into the engagement groove.

However, this requires a large washer for the nut, and furthermore, due to the dimensions of the bracket, it may not be possible to form such a large elongated hole. In this case, the bolt head cannot be inserted into the lip engagement groove.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a construction member mounting structure in which a bolt can be easily inserted into a lip engagement groove.

[Means for solving problems]

The present invention for solving the above-mentioned problems includes: a mounting bracket; a construction member in which the bracket has a longitudinally extending lip engagement groove that is open on the side thereof;
and a bolt having a substantially rectangular head for attaching and fixing the construction member to the bracket, and the bracket has a long hole extending in a direction perpendicular to the lip engagement groove through which the bolt head can be inserted. the opening width of the lip engaging groove is larger than the short axis length of the bolt head and smaller than the long axis length, and a surface portion on the side of the bracket of the construction member includes:
A shallow groove having a depth greater than the wall thickness of the bolt head and a width greater than the maximum length of the bolt head is formed to run longitudinally and communicate with the lip engagement groove. be.

[Effect]

In the present invention, a shallow groove 13 is formed. As a result, after the bolt head 51 is inserted through the elongated hole 41a, the bolt head 51 can be freely rotated within the shallow groove 13, and when the bolt head 51 is rotated, the long axis of the head 51 is aligned with the lip engagement groove 11. Along the longitudinal direction of the opening, the head 51
can be inserted into the lip engaging groove 11. In this insertion work, the current bolt head 51 is inserted into the bracket 4.
Even if it is invisible due to the presence of 1, it can be easily performed.

〔Example〕

The present invention will be explained below by taking as an example the case of a vault-like structure shown in the drawings.

This example is an example of a truncated cylindrical vault roof as shown in FIG. 2, in which the first vault X can be moved to cover the second vault Y.
In both vaults X and Y, there is a vertical support frame 1 having a substantially arc shape (actually a polygon as described later), a horizontal support frame 2 arranged horizontally perpendicularly to the vertical support frame 1, and each support frame 1,
The main components include a surface plate 3 made of a glass plate or the like surrounded by and held by a frame 2, an arc-shaped main steel frame 4 holding each of the support frames 1 and 2, and a horizontally arranged rim steel frame 5.

The vertical support frame 1 supports the lower surface of the surface plate 3, and includes a support member 10 that is bent downward into a polygonal shape (the manner of this bending will be described later), and a support member 10 that is located above the support member 10 and extends along its longitudinal direction. Presser plate 2 that holds down the top surface of face plate 3
Consists of 0.

The surface plate 3 is held by a receiving member 10 and a presser plate 20 via packings 30 and 31. Further, the holding plate 20 is integrally connected to the receiving member 10 by a connecting tool 32 and a screw 33.

On the other hand, a cross-shaped bracket B is arranged at the intersection of the vertical support frame 1 and the horizontal support frame 2. This bracket B is fixed in advance to the main steel frame 4 by welding or the like. The bracket BB includes a first bracket 41 for fixing the vertical support frame 1, and a second bracket 42 for holding the horizontal support frame 2 orthogonal to the first bracket 41 in a cross shape.

Now, focusing on how to attach the vertical support frame 1 to the first bracket 41, as shown most clearly in FIG. A bolt 50 is prepared.

On the other hand, the vertical support frame 1 is fixed to the bracket 41 with bolts 50 via the support member 10 thereof. For this purpose, a lip engaging groove 11 is formed in the lower extending portion of the receiving member 10 in a longitudinal manner and opens on the side of the bracket 41. Moreover, in the bracket 41,
A long hole 41 for inserting the bolt 50 is formed along a direction perpendicular to the longitudinal direction of the lip engaging groove 11 (in the vertical direction in the drawing). The width of the elongated hole 41a is smaller than the short axis length l and the long axis length L of the bolt head 51, and the length is sufficiently larger than the long axis length L of the bolt head 51. Therefore, with the long axis of the bolt head 51 aligned with the elongated hole 41a, there is enough room to insert the bolt 50 through the elongated hole 41a while adjusting the position by moving it up and down.

On the other hand, the lip 1 constituting the lip engagement groove 11
The opening width l' of bolts 2 and 12 is larger than the short axis length l of the bolt head and smaller than the long axis length L. Furthermore, the surface of the receiving member 10 next to the bracket 41 has a depth d greater than the wall thickness t of the bolt head 51, and a width L' of the maximum length of the bolt head 51 (in the illustrated example, the diagonal apex is A shallow groove 13, which is larger than the lip engagement length), is formed to run longitudinally and communicate with the lip engagement groove 11.

60 is a washer, 61 is a washer, and 63 is a nut. In addition, on the surface of the support member 10 next to the bracket 41, on both sides of the bracket 41, and on the surface of the washer 60 next to the bracket 41, in order to prevent displacement in the vertical direction when they are brought into close contact with each other,
Concavities and convexities are formed along the lateral direction.

The vertical support frame 1, in other words, the support member 10 is attached to the bracket 41 by the following procedure. That is, as shown in FIG. 4, the bolt head 51 is inserted into the long hole 41a while aligning the long axes thereof, and is housed in the shallow groove 13 (). Then,
The bolt 50 is rotated 90 degrees around its axis, and the long axis of the bolt head 51 is aligned with the longitudinal direction of the opening of the lip engagement groove 11 (as shown by the imaginary line in FIG. 4). Thereafter, the bolt 50 is pushed in and its head 51 is inserted into the lip engagement groove 11 (). Next, rotate the bolt 50 90 degrees around the axis (). After that, the washer 60 and washer 61 are fitted to the foot of the bolt 50, and the nut 62 is screwed together.
Proceed to screw the bolt head 51 into the bracket 4.
1, and then rip the bolt head 51.
2 and 12 (). This completes the installation.

In the above example, the bolt head 51 may have an approximately rectangular shape, such as an ellipse in length. In addition, as shown in the illustrated example, if the shape of the bolt head 51 is made into a parallelogram and the distance between the diagonal vertices is made slightly larger than the inner width of the lip engagement groove 11, it is possible to When rotated once, the corner portion hits the inner surface of the groove inner wall of the lip engaging groove 11 and stops there, making it easy to position the bolt head 51.

As mentioned above, due to the presence of the shallow groove 13, the long axis of the bolt head 51 is aligned with the elongated hole 41 in the bracket 41.
Even if the bolt head 51 cannot be inserted into the elongated hole 41a unless it is aligned in the longitudinal direction of a, the bolt head 51 can be easily inserted into the lip engagement groove 11. This effect occurs when the receiving material 10 is already fixed to another bracket and the receiving material 10 cannot be moved, or when the receiving material 10 is fixed to other brackets at both ends and the receiving material 10 is fixed to the middle bracket between them. This becomes noticeable when it is fixed.

Note that FIG. 1 also shows the mounting structure of the horizontal support frame 2 according to the present invention. 50' is a bolt, 42
a' is a long hole, 60' is a washer, and 62' is a nut.

[Effect of idea]

As described above, according to the present invention, the head of the bolt can be inserted into the lip engagement groove very easily.
