Description

[Detailed description of the invention] This invention is based on a method that, when simultaneously forming the upper floor part and the beam part of a concrete building, locks the upper edge of the temporary side plate of the temporary frame that forms the beam part. A beam for concrete construction work that can support construction beams on which temporary floor boards are placed to form slab surfaces, and can also clamp and fix temporary side boards at a fixed width to prevent them from expanding. This relates to a receiver.

When forming ceilings or floors above floors in the construction of concrete buildings, the temporary floorboards on which concrete is poured are usually constructed by laying panels, etc., but these temporary floorboards are supported by joists and This construction beam was supported by supports. However, using such conventional construction methods requires a large amount of support, and the space formed under the construction beams must also be extremely small. It was also one of the causes of problems.

To solve these problems with conventional construction methods, when simultaneously forming the upper floor part and the beam part of a concrete building, the temporary side plate of the temporary frame that is framed to form the beam part is used. It has been proposed that a receiving metal fitting for a construction beam is fixed to the upper edge and that both ends of the construction beam are supported by this receiving metal fitting. However, when supporting construction beams using these brackets, the temporary side panels of the temporary frame can be used with temporary floor boards that make up the floor part of the upper floor, joists, thick hikiki, construction beams, and even poured concrete. Since the loads such as If you use a side plate, this will expand,
Furthermore, there was a risk that the temporary frame itself would be destroyed.

In view of these problems, this invention was designed to support construction beams even if the strength of the temporary frame itself is on the same level as before, and is well adapted to the size of the temporary frame. It was devised to provide a holder that can be held securely.
It is fixed to one side of the opening of the holding body formed in the shape of a letter.
Each of the hanging plates in this holding body part has a receiving body formed by providing a wedge hole and a supporting piece having an opening in the vertical direction, and a receiving body formed by providing a wedge hole and a support piece having an opening in the vertical direction, and 1 is a fixing device body formed by installing a wing setting piece in advance with a wedge hole that communicates with the cylinder body, and providing support pieces having openings in the vertical direction on both sides of the cylinder body. A support formed by connecting a pair of support rods with a connecting piece can be inserted into each support piece for the receiver body, and can be vertically hung and connected by inserting it into each support piece and supporting the fixture body. The reason is that

An embodiment of this invention will be described below based on the drawings.

That is, the receiver according to this invention includes a receiver body 1, a fixture body 2, a support body 3, and wedges 4, 5 and pins 6 used as means for fixing these members.
It is composed of.

The receiver main body 1 has a locking piece 7 hanging downward on the upper part, and has reinforcing pieces 8 on both sides that are folded back toward the back, and has a hanging part 9 that has a substantially 7-shaped side surface.
and a holder part 10 which is integrally fixed to the hanging part 9 by being held by the reinforcing piece 8. This holding body part 10 has a substantially inverted U-shape in longitudinal section, and one opening side of both hanging plates 11 of the holding body part 10, which is closer to the hanging part 9, is provided with a wedge 4 to be driven. It has a wedge hole 12 formed corresponding to the longitudinal cross-sectional shape, so that the wedge 4 can be inserted and locked freely. According to the illustrated example, since the vertical cross-sectional shape of the wedge 4 is approximately an inverted L-shape, the wedge hole 12 is also formed in a shape corresponding to this. Both hanging plates 11 of the holding body part 10
Support pieces 13 each having a substantially U-shape are attached to the other side of the opening, with an opening 14 positioned in the vertical direction.

The fixing device main body 2 has a cylindrical body 15 having a substantially square-shaped longitudinal section.
A wing setting piece 16 is provided upright in the cylindrical direction on the upper surface of the cylindrical body 15, and an opening 14 is provided at the ends of both side surfaces of the cylindrical body 15 in the same manner as the support pieces 13 of the receiver main body 1. A wedge hole 18 for driving a wedge 5 is integrally formed in the wing setting piece 16 and a part of the cylinder body 15 adjacent thereto. . The wing setting piece 16 has an abutting edge 19 that is directly above the opening side edge of the cylindrical body 15 and an end edge thereof, and a pin 6.
It has a locking hole 23 through which it is inserted and locked.

The support body 3, which is vertically suspended between the receiver body 1 and the fixture body 2, is composed of a pair of support rods 20 and a connecting piece 21 that connects the support rods 20 to each other, and the cross-sectional shape of the support rods 20 is as follows. The support rods 20 are connected to each other by interposing connection pieces 21 at appropriate positions on the outer sides of the support rods 20 by locating the opening sides on opposite sides. The connecting pieces 21 are arranged at appropriate intervals between the supporting rods 20, that is, the spacing is such that the pair of supporting rods 20 can be slid freely through each supporting piece 13 of the receiver main body 1 and each supporting piece 17 of the fixture main body 2. can be formed and supports 2
0 may be used as long as they can be fixedly connected to each other.
In addition, a plurality of pin insertion holes 22 are provided in the lower portions of the opposing surfaces of the support rods 20 in the vertical direction so that the pin 6 can be inserted therethrough, with their positional relationship matching. .

Note that the wedge 4 driven into the fixture body 1 to support and fix the construction beam B is connected to, for example, a hanging part 9 at an appropriate position via a chain or the like, and is connected to the pin 6 used in the fixture body 2. The wedge 5 can also be connected, for example, to a suitable position on the wing piece 16 via a chain or the like.

The use of this will now be described with reference to FIGS. 2 and 3.

Of the temporary frame body 30 consisting of a temporary bottom plate 31 and a temporary side plate 32, which are framed to form a beam by pouring concrete C, the support body 1 is hung at an appropriate position on the upper edge of the temporary side plate 32. It is locked through the locking piece 7 of 9.
After that, the end of the construction beam B is inserted into the holding body part 10 of the receiver body 1, and the wedge 4 is driven through the wedge hole 12 to support and fix it. The other end of B is similarly fixed to another receiver main body 1. On the other hand, the fixing device main body 2 is externally fitted to the large tension member 34 that cross-supports the temporary bottom plate 31 of the temporary frame body 30 via the thick end member 33, and the respective supporting pieces The respective support rods 20 of the support body 3 are vertically mounted via 13 and 17 to connect them to each other. This support body 3 is positioned at an appropriate length corresponding to the vertical width of the temporary frame body 30, and is secured to the cylindrical body 15 of the fixture body 2 by fixing it with a pin 6 through the locking hole 23 of the wing installation piece 16. It is pivotally supported in such a way that it cannot be removed.
The fixing device body 2 is forcibly moved along the fitted large tension member 34 to the temporary frame 30, so that the support body 3 and the abutment edge 19 of the wing installation piece 16 in the vertical frame state are connected to each other. 35 which is suspended horizontally on the temporary side board 32
By driving the wedge 5 into the wedge hole 16 to maintain this pressure contact state, the fixture main body 2 is securely fixed to the large pull member 34, and the support S pressed from below To support. Temporary side plate 3
The support 3 is in pressure contact with 2 through the support 35.
Since the support rods 20 constituting this have a U-shaped cross section and have high strength, they can resist the load on the temporary side plates 32 and prevent them from expanding.
In addition, since the pair of support rods 20 are fixed by the connecting pieces 21, the work of vertically mounting the support body 3 on the support body 1 and the fixture body 2 can be done in one go. Pin insertion hole 22 between rods 20
and the wing installation piece 1 interposed between this pair of support rods 20.
Since its position can be easily matched with the locking hole 23 in 6, the pin 6 can be inserted very easily, which greatly contributes to improving work efficiency. The above is carried out in exactly the same way for the temporary side plate 32 on the opposite side of the temporary frame body 30, and the crossbar on the construction beam B is prevented from expanding in the temporary frame body 30. Temporary floor plates P are laid out on the slab surface 36, and concrete C can be placed on the slab surface and inside the temporary frame body 30 to form a concrete floor and a concrete beam at the same time.

As mentioned above, according to this invention, the upper floor part and the beam part can be formed at the same time using an extremely small number of supports and without particularly strengthening the strength of the temporary frame itself for forming the beam part. In addition, it can be flexibly adapted to the required height of the beam to be formed, and it is easy to assemble and remove, which greatly contributes to improving work efficiency in construction work. It is possible to achieve extremely excellent practical effects such as.
