DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a beam forming apparatus for use in the construction of a beam with a wall in which a concrete beam is connected to the upper end of a concrete wall. Related to improvement of receiving brackets.

[0002]

2. Description of the Related Art Conventionally, when constructing a beam with a wall, a measure has been taken to support a beam form using a pipe support together with auxiliary materials such as a joist and a pulling bar.

[0003] That is, there are two types of construction of a beam with a wall: a case where the wall and the beam are integrally constructed, and a case where the wall is first constructed and then the beam is continuously connected. Even in the case of, in general, the wall body is built using a wall formwork device, a wall formwork device including a vertical end and a lateral end as an auxiliary material and a fixture, The beam is said to be built using a beam form device including a beam form, joists and sculptures as auxiliary materials, fixtures and pipe supports as supports, and the like.

[0004] Therefore, regarding the preservation (curing) of the formwork after the concrete is cast, generally, the wall formwork device is dismantled after the lapse of the curing period of the wall, irrespective of the curing period of the beam, that is, the wall mold is dismantled. The removal of the frame becomes possible, and the wall form can be reused.

[0005]

However, when the beam form is narrow and the wall form and the beam form are intricate while being close to each other, only the wall form is used. In some cases, dismantling and removal may not be possible prior to the beam formwork device.

That is, when building a beam with a wall, the beam form device is built after the wall form device is built. If the support is not removed, the wall form device may not be able to be removed. In this case, the inconvenience that the wall form device cannot be reused in the wall form device is brought.

Further, in order to avoid the above-mentioned inconvenience, there is a case where the pipe support is arranged and used so-called diagonally so that the pipe support does not interfere with the already built wall formwork device. In this case, the pipe support does not function sufficiently mechanically as a predetermined support, or the pipe support falls down on the way due to an insufficient anchoring structure around the underbody or head, or
There is a danger that it may be inconvenient, for example, because it may hinder the work in the surrounding area.

The present invention has been made in view of the above circumstances, and has as its object to form a formwork apparatus which is most suitable for use in building a walled beam having a beam body at an upper end. Is to provide a beam receiving bracket.

[0009]

Means for Solving the Problems To achieve the above-mentioned object, the structure of the present invention is applied to a vertical member which is adjacent to a wall form from which the wall is formed and an upper end portion of the vertical member. A cross member whose base end portion is integrally formed and whose upper end surface faces the beam bottom, an upper end portion is connected to a distal end portion of the cross member, and a lower end portion is connected to a lower end portion of the vertical member. And a beam receiving bracket comprising: a beam receiving bracket having an upper end portion rotatably connected to a distal end portion of a cross member, while a lower end portion is separable from a lower end portion of a vertical member. The connecting portion is connected to the upper end of the vertical member or the horizontal member, and the engaging portion is formed so as to be separably engaged with a mounting portion detachably mounted on the upper end of the wall formwork. A large support is provided at the upper end of the cross member to enable height adjustment, and the vertical member is fixed to the wall by a suitable fixing device. It is an formed by Uni formed.

[0010] Preferably, the fixing tool is a foam tie for forming a wall form by screwing over a wall form to a separator embedded in the wall, and a wall on which a vertical member is provided adjacently. It is assumed that the formwork is made small enough to be adjacent to the vertical members and to be a minimum required size.

[0011]

Therefore, the mounting bracket is hung so as to be hooked on the upper end of the wall form, and the locking section is locked to the mounting section, so that the beam receiving bracket is attached to the outer surface of the wall form. This makes it possible to temporarily set the device in the adjacent state.

Then, for example, a form tie as a fixing tool is screwed into a tip of a separator embedded in a wall projecting toward the vertical member through the wall form, and the vertical member is crimped to the wall form. Can be installed next to the vehicle.

When the wall form is formed from this state, the lower end of the cross member is separated from the lower end of the vertical member, so that the lower part of the horizontal member is open, and the pipe having a thicker horizontal end is used. Facilitates the installation work.

When the beam form is formed, the large form provided on the upper end side of the cross member is adjusted with fine adjustment so that the beam form can be formed.

Further, concrete is poured into the wall formwork and the beam formwork, respectively, and in the case of the wall formwork in which the concrete has solidified and the curing has been completed, the beam receiving bracket is removed from the wall formwork. It is possible to continue curing the beam without removing it.

When the wall form w adjacent to the beam receiving bracket B is formed into a small panel as described above (see an imaginary line diagram in FIG. 2), the beam receiving bracket B is provided. With the bracket B left adjacent to the small panelized wall form w, only the other fixed wall form w is attached to the wall W
The beam receiving bracket B can be reused by being detached from the main body, and there is an advantage that it is not necessary to tamper with the beam receiving bracket B during the curing period of the beam T.

Further, when the beam receiving bracket B itself is to be removed, the washer 43 is lowered by screwing the bolt 42 of the large receiving member 4 disposed on the cross member 2, so that a so-called loose state is obtained. At this time, the pulling t1 and the joist t2 are removed to secure a space where the beam receiving bracket B can be lifted.

After that, the beam receiving bracket B is lifted, and the locking portion 7 is separated from the mounting portion 6 constituting the support portion 5, so that the beam receiving bracket B is moved from its mounting position. Removal is possible.

When the beam form t is detached from the bottom surface of the beam T, the mounting portion 6 forming the support portion 5 can be removed, and the beam receiving bracket B can be reused together with the beam receiving bracket B. Become.

In the above description, the case where the beam with wall has the narrow beam T is described as an example. According to the structure of the present invention, the beam T has a normal width. Of course, even if it is set to have, it can be used.

Further, according to the configuration of the present invention, the beam receiving bracket B can be used as a so-called floor receiving bracket when a floor is connected to the upper end of the wall W.
