Abstract

PURPOSE:To smoothen the fitting of cut beam, etc., to waling by a method in which a receiver having a porjected circular peripheral face is rotatably coupled with a coupler having a curved face fittable with the receiver and both the receiver and the coupler are fixed at any position. CONSTITUTION:Since the peripheral face 11a of a receiver 11 is slidably contacted with the circular face 12a of a coupler 12, the angle of a cut beam 2 to a waling 1 can be freely set up. Accordingly, the receiver 11 and the coupler 12 are clamped by using a clamping metal 14 consisting of a forked body 14a and paired left and right-handed clamping bolts 14b, being held at a necessary angle. In this case, both the receiver and the coupler 11 and 12 can be fixed by putting the body 14a between the faces of both the receiver and the coupler 11 and 12 and then screwing the clamping bolts into them.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is a flexible piece that can be used as a part of a retaining material used when constructing reinforcing bars or underground structures of steel-framed buildings, or as a part of shoring that supports concrete formwork, etc. It is related to.

First of all, talking about the heaping material, when it comes to the heaping, it is necessary to securely fasten it with the sillage, the sill straddling the sill, and the flint to enhance the fulcrum effect. However, as is well known in recent years, it is difficult to obtain all the land, so building sites are rarely rectangular, and often include diagonal areas, as shown in Figure 1. If the strait 1) and the strut (2) are perpendicular to each other, it is not so troublesome to install them, but if the strait 1) is diagonal to the strut, the second to
As shown in Figure 4-1, the installation work is troublesome and takes a long time, and improvements have been desired. In other words, select a bracket (3) that matches the set angle for the illumination, or manufacture a new one, and then remove it.
After that, cut the beam (2) or fire it (5).
After installation, concrete (6) was placed on the end face to secure it in place. Also, as shown in Figure 4, it has recovered! ■)
After attaching the joint plate (7) with bolts, it is processed on site to a shape that matches all the set angles of the H-beam steel.
In addition, a receiver made by welding an end brake) (4a)
4) There are cases where the entire assembly is made and then welded to the above-mentioned joining plate, and in each case, the installation must be done in accordance with the situation at the site, which is extremely tedious and time-consuming. Moreover, the construction required a long period of time. This also applies to the case where the diagonal beam (8) is attached, as shown in FIG. 5, and the same custom-made hardware (9) as described above is required.

The present invention is mainly concerned with the complete construction of a flexible piece that can overcome the above-mentioned points in the construction of piles, but this flexible piece can also be used as a flexible piece for general shoring work as described later. This point is also included in the scope of the present invention, since it is also possible to use it.

The present invention will now be described in detail based on the illustrated embodiments. As shown in FIGS. ) and a concave curved surface (12a) that fits the receiving member.
), and an end plate (12b) for connecting to the strut (2) or the flint (5) is attached to the end face of the engaging member.

Note that the joint plate 00) has a bolt hole (10
a,) are drilled, and bolt holes (12Q) are similarly provided in the end plate on the side of the force engaging member. Further, a reinforcing plate 03 is provided on both the receiving member 01) and the engaging member α2).
) can be attached.

The receiving member circle and the engaging member (12+ are used in combination as shown in FIG. 9, and the peripheral surface (lla) of the receiving member
and the arcuate curved surface (12a) of the engaging member 02) are brought into contact with each other, and then both are fixed with the fastening fittings shown in FIGS. 10 and 11. In other words, since the contact surfaces of the receiving member and the engaging member are engaging surfaces that can be slid against each other, as shown in FIG. ) (Moshikake Hiuchi (5)) angle is
You can set this freely. Therefore, after holding this angle at the required angle, the fastening fitting is tightened using the receiving member (11), the engaging member 02, and the entire fastening fitting side.The main body (14a) has a bifurcated shape. and a pair of left and right tightening poles) (
14b), so by inserting the main body (14a) into the abutting surfaces of both members Uυ (12) and screwing in the tightening bolt, the two are tightly fixed. After doing this, the end plate (12b) on the retaining member α is matched with the strut (2) or the flint (5), and both are tightened with bolts (QS). The assembly is as shown in Figures 20 and 21. According to the present invention, the complicated work of producing custom-made receiving pieces by on-site processing and pouring concrete, which were previously required, is completely eliminated. Since it is possible to omit this, it contributes to labor saving and at the same time shortens the construction period.

FIG. 12 uses the same members as shown in FIGS. 6 to 11,
This figure shows the case of attaching a diagonal beam (8) in pile-stopping work, and differs from the previous embodiment only in that the direction of the arc-shaped curved surface (lla) on the receiving member aυ is rounded when viewed from the side. be. In other respects, the structure is the same as that of the previous embodiment, so the same reference numerals are used to denote each member. As described above, the direction of the circular arc surface of the receiving member in the present invention can be freely set, and this also applies to each of the embodiments described below.

The embodiment shown in FIGS. 13 and 14 is an example in which it is not necessary to use the fastening metal fittings shown in the previous embodiment. That is, in this case, on the side of the engagement member, locking plates α7) (17) are welded to both the upper and lower surfaces of the concave portion 0Q formed inside the arcuate curved surface (12a), and these locking plates The receiving member 01), which is attached to the upright side, is completely fitted between the plates and fixed. In this way, it is not necessary to use the above-mentioned tightening metal fitting θ, but it goes without saying that this metal fitting (14) may also be used for tightening. Incidentally, in Figures 15 and 16, the locking plate is attached to the side of the receiving member, but no locking plate is attached to the corresponding engaging member side, and the locking plate is simply shown on the right side of Figure 8. This is a case where the configuration is similar to that. The reference numeral 0 barrel indicates a locking plate on the receiving member side, and the retaining member α may be fitted between the locking plates disposed above and below (see FIG. 16).

Next, the embodiment shown in FIGS. 17 to 19 will be described.

The one shown in the same figure has elongated holes as shown in FIG. (11
After drilling and aligning the elongated holes with and in the vertical positional relationship, insert a concave-convex washer (20
a) This is an example in which (20b) is applied and both are tightened and fixed with bolts and nuts (21). Even when this is done, both the receiving member and the engaging member are connected to the receiving ring (
11d) can be slid relative to each other with the center as the axis, so the angle of the strut, flint or diagonal beam can be set arbitrarily, and even when both are slid, the elongated hole Ql allows It is possible to conclude both.

To illustrate the case in which actual pile-stopping work is carried out using each of the above-mentioned members, it is shown in Figures 20 and 21. It can be done extremely smoothly.

By the way, since the flexible piece of the present invention has the above-described configuration and effects, it can also be used as it is as a universal joint in general shoring. The universal joint J used for general shoring is shown in Figure 22, and as an example, as shown in Figure 23, it is used for shoring to support concrete formwork during bridge pier construction. In some cases, it is used where the supported member is oblique or curved. As is clear from Figure 22, this joint supports the load with the pin P in the center, so it cannot withstand large loads, and in order to increase the fulcrum effect, it is necessary to prevent rotation. However, if the flexible piece of the present invention is used in place of the universal joint J in this part (see Figure 24), This has a revolutionary effect in that all of these inconveniences are eliminated and the purpose can be achieved much more cheaply than using a universal joint.
