Description

[Detailed Description of the Invention] The present invention relates to a connecting device for panels, etc., and particularly to a connecting device used when connecting two concrete panels etc. that have been fixed in advance.

In civil engineering, construction work, etc., there are cases where a plurality of concrete panels must be formed separately and these panels must be connected.

In such a case, as shown in Figure 1, bury a pair of screws N and N' for attaching the connecting device described later in the opposing surfaces of the panels P and P' that are to be connected to each other. , the panels P and P' are connected by attaching a connecting device using these paired screws N and N'.

Note that A is a steel bar for an anchor for fixing screws N and N'.

However, as shown in Fig. 2, the conventional connecting device has screws N,
The connecting bolts N and 1' are screwed to N', and the washer 2 and nut 3 are screwed to the ends of these connecting bolts 1 and 1'. The panels P and P' are connected by screwing the female screw cup 4 into the nut 3.

Therefore, as shown in Fig. 2, the positions of the screws N and N' match, and the axes C1 and C7 of the connecting poles H and 1' screwed together.
If '' is in a straight line, the female screw cup 4 can be screwed onto the nut 3, but the positions of the screws N and N' do not match, and the shaft center of the connecting pole (1.1') C7,C
If 7' are shifted from each other, there is a drawback that the female screw cup 4 cannot be screwed into the nut 3, that is, the panels P and P' cannot be connected.

The present invention eliminates these drawbacks and allows the panels P and P' to be reliably connected even when the axes C1 and Cl' of the screws N and N' to the connecting poles H and 1' are misaligned. This was done to provide a connection device.

Next, an embodiment of the present invention will be described based on the drawings from FIG. 3 onwards.

11.11' is a pair of connecting bolts having heads 11a, 11a'.

These connecting bolts 11° 11' have heads 11a, 11
The diameter d1 of a' is 26 mm, the shaft part 11 b, 11
The diameter d2 of b' is 18 mm, the length l of one connecting bolt 11 is 85 mm, and the length l of the other connecting bolt 11 is 1.
The shaft portion 11 b is formed to have a size of approximately 15 mm.
The tips can be screwed into screws N and N' of panels P and P', respectively.

Reference numeral 12 denotes an axial hole provided in the end plate 12a so that the axes C1 and C7' of the connecting bolts 11 and 11' are shifted from each other, and the heads 11a and 11a' are brought into contact with each other. 12b, and the other connecting bolt 11'
It is a screw cup to which these connection bolts 11 and 11' can be attached with the tips of the screws protruding from the open end side.

The screw cup 12 has an outer diameter d1 of 45 mm and an inner diameter d2 of 3 mm.
5 mm, length l is 70 mm, wall thickness t of end plate 12a
is formed to have a size of approximately 12 mm, and a thread groove 12C is cut over approximately 25 mm on the open end side of the inner circumferential surface.

In addition, the shaft hole 12b has a diameter d3 of about 19 mm,
The center C13 is located at a position eccentrically outward by about 5 mm from the axis Cl of the screw cup 12.
As shown in FIG. 3, the allowable eccentricity e of the connecting bolts 11 and 11' within the screw cup 12 can be set at a maximum of 10 mm.

13 is screwed onto the open end side of the screw cup 12, and a connecting bolt 11.11 is inserted between its tip and the end face plate 12a.
This is a fixing cap that clamps and fixes the heads 11a and 11a' of the '.

The fixed cap 13 has a thread groove 13 screwed into the screw cup 12 on one end side of a cylindrical body with an outer diameter d1 of 36 mm, an inner diameter d2 of 29 mm, and a length l of about 3.7 mm.
A is provided in a protruding manner, and a hexagonal flange portion 13b having a maximum diameter of about 53 mm is provided at the other end.

Note that 14 is the tip of the screw cup 12 and securely tighten the connecting bolt 1.
1' is an eccentric washer interposed between the head 11a' and the screw cup 12 in order to suppress the head 11a'.

The washer 14 has a diameter d1 of 35 mm and a wall thickness t of 12 mm.
A shaft hole 14a having a diameter d2 is provided at a position eccentric about 5 mm outward from the center C.

Next, we will discuss how to use it.

First, one of the connecting bolts 11 is inserted into the screw cup 12, and the shaft portion 11b is pulled out from the shaft hole 12b.

Then, the tip of the shaft portion 11b is screwed into the screw N of one panel P.

At the same time, an eccentric washer 14 and a fixing cap 13 are attached to the shaft rod portion 11b' of the other connecting bolt 11', and the shaft rod portion 1
Screw the tip of 1b' into the screw N' of the other panel P',
After that, the screw cup 12 and the fixed cap 13 may be screwed together, even if the axis Cl of the connecting bolts 11 and 11' is
Even if Cl′ is shifted, the shift is lQm
If the deviation is within m, the deviation is absorbed by the screw cup 12 and the fixing cap 13, and the panels P and P' can be firmly connected.

In the embodiment shown in the drawings, the shaft hole 12b of the end plate 12a is made eccentric in order to increase the eccentricity tolerance e of the connecting bolts 11 and 11'.
does not necessarily have to be eccentric.

As explained above, the present invention has two heads 11 a and 11 a'.
A pair of connecting poles) 11.11' and these connecting poles) 11.11' and the head 11 with the axes of
a, 11a' and one connecting bolt 11
The screw cup 12 is designed to be able to be attached with the tip of the connecting bolt 11' protruding from the shaft hole 12b provided in the end face plate 12a, and the tip of the other connecting bolt 11' protruding from the open end side. A connecting bolt 11. is screwed into the open end side and is connected between the tip thereof and the end face plate 12a.
11', and a fixing cap 13 that clamps and fixes the heads 11a, 11a' of the panels 11', and screws N, N' provided on the panels P, P'. The position of the connecting port H that was screwed to this does not match.
, 1', even if the axes C1 and C7' are slightly shifted from each other,
This has the effect of absorbing the deviation and ensuring reliable connection.
