Abstract

(57) [Summary] [Objective] The present invention aims to provide a beam-receiver-free piece that facilitates spatially free joining. [Structure] The beam-removable piece of the present invention is characterized by using a pair of cylindrical pins.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a beam receiving piece that can be spatially freely joined when an abdomen and a girder or the like are diagonally joined in a mountain retaining method.

[0002]

[Prior art]

 In recent construction work for underground structures, the reverse construction method has been adopted in place of the conventional excavation method, and this construction method constructs structures sequentially from the upper basement floor to the lower basement floor while excavating the underground. After constructing the slabs and beams on the upper basement floor, it will be necessary to excavate for the lower basement floors, and it will not be possible to place cut beams on the Yamadome wall. Since it becomes necessary to support the mountain retaining wall diagonally as shown in Fig. 5, there is a demand for the development of a beam-receiver-free piece that spatially and freely joins uprising beams and the like.

[0003]

[Problems to be solved by the device]

 An object of the present invention is to provide a beam-removable piece that solves the above conventional problems and facilitates spatially free joining.

[0004]

[Means for Solving the Problems]

 In order to achieve the above object, the present invention comprises an upper member having a pin, a lower member having another pin arranged at right angles to the pin, and a recess into which the pair of pins are slidably fitted. It proposes a beam-removable piece consisting of the intermediate member of 1.

[0005]

【Example】

 A beam receiving universal piece of the present invention will be described below with reference to an embodiment shown in the drawings. 1 to 3 show a beam receiving free piece of the present invention, which has an upper member (1) having a cylindrical pin (1b) fixed to a main body (1a).

Next, a lower member (3) to which a cylindrical pin (3b) is fixed is provided on the main body (3a). The pin (1b) of the upper member (1) and the pin (3b) of the lower member (3) are arranged at right angles to each other.

The upper and lower pins (1b) and (3b) are slidably contacted with the intermediate member (2). That is, the pin (1b) of the upper member (1) is slidably fitted in the recess (2b) on the upper surface of the main body (2a) of the intermediate member (2).

On the other hand, the pin (3b) of the lower member (3) is slidably fitted in the recess (2c) in the lower surface of the main body (2a) of the intermediate member (2). That is, the upper and lower recesses (2b) and (2c) of the intermediate member (2) are perpendicular to each other.

The pins (1b) and (3b) are fixed by bolts (9), but it is the contact surfaces of the pins (1b) (3b) and the recesses (2b) (2c) that receive the compressive force. The operation of the beam receiving piece of the present invention shown in the above embodiment is as follows.

That is, the upper member (1) is butted against, for example, the abdomen, while the lower member (3) is butted against, for example, a small beam. When they are spatially inclined, the upper member (1) rotates on the pin (1b) and the lower member (3) rotates on the pin (3b).

Since the pair of pins (1b) and (3b) are arranged at right angles, the upper member (1) and the lower member (3) can be spatially inclined arbitrarily.

[0012]

[Effect of device]

 The embodiment of the beam receiving free piece of the present invention is as described above, and its effects are listed below. (1) Since the beam-receiver-free piece of the present invention uses a pair of cylindrical pins, it is easier to manufacture than a ball. (2) Since the beam-receiving piece of the present invention uses a pair of cylindrical pins, the size can be easily changed according to stress.
