Description

The present invention is a suspension for construction of an outer wall panel with a hollow hole, which is used for lifting a hollow outer wall panel having hollow holes formed in the vertical direction inside and transporting the hollow outer wall panel to a predetermined mounting position in the outer wall panel installation work of a building. Regarding ingredients.

Conventionally, in the construction work of the outer wall of a building, when the outer wall panel with a hollow hole (hereinafter, simply referred to as the outer wall panel) P that has been carried to the construction site and laminated is suspended and transported to a predetermined mounting position, As shown in FIG. 17, slinging is performed by winding the outer wall panel P with a nylon sling N, and in this state, the outer wall panel P is hung by a crane or the like (not shown), transported, and mounted at a predetermined mounting position. Was there.

However, when the nylon sling N is transported by winding the body, the outer wall panel P is liable to crack when the outer wall panel P is suspended, and in that case, the outer wall panel P may fall, which is extremely dangerous. Further, in the outer wall with stones and tiles, the members to be attached may be peeled off due to the tightening of the nylon sling N, which is dangerous.
In view of such circumstances, the applicants have previously proposed a hanging tool for a hollow outer wall panel disclosed in Patent Document 1.

A direction orthogonal to the surface direction of the outer wall panel P, that is, the thickness of the outer wall panel P, is inserted into the insertion hole 102 with the bottom plate 101 integrated with the receiver 100 formed in the vicinity of the lower side of the receiver 100 protruding from the other end side opening. A support 103 having a pull-out prevention mechanism is inserted above the bottom plate 101 from the orthogonal direction, and the support 103 supports the lower end side of the outer wall panel P when the support 100 is lifted by a crane or the like of the lifting rope R. It was made to be lifted in this way.

Japanese Patent No. 3816358

Due to the structure as described above, it is safe to prevent the nylon sling N from falling due to cracking of the outer wall panel P due to the body winding and the peeling of the sticking member on the stone or tiled outer wall due to the tightening of the nylon sling N. However, it had the following new problems. That is, when the outer wall panel that has been lifted by a crane or the like and transported to a predetermined mounting position is seated above the base of the foundation or the outer wall panel located below, the support tool is sandwiched between the outer wall receiving metal fitting and the outer wall panel. , It has happened that it cannot be pulled out unless a tool such as a crowbar is used. Furthermore, there is a risk of scratching the outer wall panel by using the crowbar or pinching the hand in the outer wall panel when pulling out the crowbar. Further, in the outer wall panel having the sticking member such as stone or tile, there is a problem that the sticking member is peeled off.

The present invention has been made in view of the above problems, and the support can be easily removed without using a tool such as a crowbar, there is no risk of pinching the operator's hand, and the outer wall panel. It is an object of the present invention to provide a hanging tool for construction of an outer wall panel with a hollow hole in which the attachment member to the mounting member hardly peels off.

In order to achieve the above object, the hanger for constructing an outer wall panel with a hollow hole according to the present invention lifts the outer wall panel with a hollow hole in which the hollow hole is formed in the vertical direction and conveys it to a predetermined mounting position of the building. A hanging tool used in the case of a receiver having a U-shaped cross section that can enter and exit the hollow hole of the outer wall panel with a hollow hole and has a hanging portion for hanging a lifting rope. With the receiver inserted into the hollow hole, it can be detachably inserted from the tip side into an insertion hole formed in the vicinity of the lower end of the receiver in a plane direction orthogonal to the thickness direction of the outer wall panel with the hollow hole. A support that is longer than the width of the hollow hole that has been worn , and an operation plate that is fixed to the rear end side of the support and has side surfaces that are substantially parallel to the support at predetermined intervals. To be equipped with.

It is characterized in that the side surface portion of the operation plate is provided with a pull-out prevention mechanism for preventing the support tool from pulling out from the insertion hole.

The pull-out prevention mechanism is characterized in that it is a recess in which the outer peripheral portion of the lower end of the receiver is fitted into the side surface portion.

The operation plate is provided with an opening for a hand grip portion.

The support is what is the rear end side substantially parallel to the distal end side said side portion in L-shape, characterized in that it is fixed to the operation plate.

It is characterized in that a protruding portion for preventing hand pinching is provided on the surface of the operation plate.

The distance between the tip of the support and the side surface thereof is substantially the same as the distance between the outer peripheral edge of the insertion hole and the edge of the receiver on the operation plate side.

It is characterized in that a stepped portion for mounting the receiver on the outer wall receiving metal fitting is formed on the lower end side of the receiver on the side opposite to the operation plate.

According to the present invention, in a state where the receiver is inserted into the hollow hole, the insertion hole formed in the vicinity of the lower end of the receiver in the plane direction orthogonal to the thickness direction of the outer wall panel with the hollow hole is formed from the tip side. Since the support tool having a length longer than the width of the hollow hole that is detachably inserted supports the lower surface of the outer wall panel with the hollow hole and is lifted and conveyed by the lifting rope, the support tool is inserted into and pulled out from the insertion hole. At that time, since there is no outer wall receiving metal fitting that obstructs the moving direction of the support and the place of attachment / detachment, there is no contact and the work proceeds smoothly. This is because the length of the support is longer than the width of the hollow hole, so that the lower surface of the partition member inside the outer wall panel forming the hollow hole is supported by both ends of the support and lifted.

Further, fixed to said support rear end of, and, by having a operation plate having substantially parallel side portions opened the support by a predetermined distance, the operation plate worker by hand Since it can be operated, the work of inserting and removing the support tool into the insertion hole becomes easy. If the operation plate is formed with an opening for a hand grip portion, there is an advantage that the work efficiency is still improved.

If the distance between the tip of the support and the side surface is formed so as to be substantially the same as the distance between the outer peripheral edge of the insertion hole and the edge of the receiver on the operation plate side, the receiver can be received. Since the support tool can enter the insertion hole only at a position where the tool and the operation plate are orthogonal to each other, the operation plate can always be held at an angle that is easy to grasp.

Further, if the side surface portion of the operation plate is provided with a pull-out prevention mechanism for preventing the support tool from pulling out from the insertion hole, the risk of the outer wall panel falling from a high place during transportation can be eliminated. There are advantages that can be done. If this pull-out prevention mechanism is formed with a recess in which the outer peripheral portion of the lower end of the receiver is fitted in the side surface portion, the outer wall panel gradually moves in the vertical direction when the lifting rope is lifted by a crane or the like. When the load is applied to the support rod as the load is changed, the outer peripheral surface of the lower end of the receiver naturally enters the recess and the operation plate becomes immobile, so the support fixed to this is also immobile. You can't get out of it and you can maintain your safety.

Furthermore, in case of providing the protrusion for preventing Tabasami the surface of the operation plate, the butt out portion even when the operation plate while working with the operating plate is rotated to the receiving fixture direction and operation plate It is safe because it creates a gap between it and the side of the receiver.

By forming a stepped portion on the outer wall receiving bracket on the lower end side of the receiving tool on the opposite side to the operation plate, the weight of the outer wall panel placed in a predetermined place by the crane is received by the outer wall receiving metal fitting. Since it is deposited in the metal fittings, the support can be safely removed from the receiver.

The best embodiment of the present invention will be described below with reference to the drawings. As shown in FIG. 1, the hanger 1 for constructing an outer wall panel with a hollow hole (hereinafter, simply referred to as a hanger) 1 of the present invention has a receiver 2 and a support 3 as main components.

As shown well in FIGS. 1, 5 and 6, the receiver 2 is provided with two side plates 22 on both sides of the U-shaped cross section 21 on both sides thereof, and the support 3 is inserted in the lower portion. The insertion hole 23 is formed. The receiver 2 has a quadrangular vertical and horizontal width dimension so that it can enter and exit the vertically long hollow hole S penetrating from one end side to the other end side inside the outer wall panel P. The vertical dimension of the hollow hole S is equal to or less than the length in the thickness direction of the outer wall panel P, and the width dimension, that is, the dimension in the surface direction of the outer wall panel P orthogonal to the thickness direction is determined by the spacing distance of the partition member P1 provided in the internal space. Be done. Since this spacing distance differs for each outer wall panel P depending on the strength required for the outer wall panel P, a small-sized receiver 2 having a certain degree of versatility is suitable.

Both ends of the hanging shaft 24 are supported by the two side plates 22, and the other end of the lifting rope R is connected to the hanging shaft 24 so that one end side can be lifted freely by a crane or the like. A hooking portion 25 to which the sides are connected is formed. Further, round washers 22a are fitted on both sides of the lifting rope R to which the hanging shaft 24 is connected, and the space between the U-shaped portions 21 in the cross section is closed without any play.

If the cross-sectional shape of the support 3 is circular, the hole shape of the insertion hole 23 corresponds to the circular shape, but the hole shape of the insertion hole 23 varies depending on the cross-sectional shape of the support 3. Further, in this embodiment shown in FIG. 1, the entire receiver 2 forms a U-shaped cross section 21, but only the upper portion requiring the two side plates 22 and the lower portion does not have a U-shaped valley portion. Is more stable because the load of the outer wall panel P transmitted from the support portion 3 applied to the insertion hole 23 can be received by the entire inner surface of the insertion hole 23.

At the corner on one end side of the lower portion of the receiver 2, a step portion 26 partially cut out at a position slightly higher than the upper end of the insertion hole 23 and a step surface 26a formed by the step portion 26 are formed. Has been done.

The support tool 3 has a role of supporting the load of the outer wall panel P by inserting it through the insertion hole 23, and the cross-sectional shape thereof may be circular or another shape as shown in FIG. 1 or the like. It is good, but in the case of a circular shape, there is an advantage that it can rotate inside the insertion hole 23. The length of the support 3 is not particularly limited, but is longer than the width of the receiver 2 so as to project outward from both lateral sides of the receiver 2 and a hollow hole in the outer wall panel P. It must be longer than the distance between the two partition members P1 forming S. Further, it may be linear or the rear end side may be bent in an L shape. When it is bent, it is easy to operate it in the insertion / removal direction as a hand grip, and it is also easy to connect it to the operation plate 4.

The operation plate 4 is a plate material for facilitating the operation of the support 3, and has a side surface portion 41 that is substantially parallel to the opening direction of the insertion hole 23 and is at the same height position. The support 3 is fixed to the one side end surface 42 in the direction perpendicular to the side surface portion 41 by welding or the like. This embodiment is a case where the rear end side of the support 3 is bent into an L shape, but in the case of a linear shape, the side surface on the receiver 3 side is as in the other embodiment shown in FIG. It is fixed to the portion 41 by welding or the like. The L-shape shown in FIG. 1 has the advantage of being more stable without peeling off because a larger area of the welding fixing 43 with the operation plate 4 can be taken. Of course, the support 3 and the operation plate 4 may be integrally molded. Further, the operation plate 4 is provided with an open hand grip portion 44, whereby the operator is hung on the lifting rope R and pulls the outer wall panel P being conveyed to a desired mounting position to guide the operator. There is an advantage that accurate work can be done safely and efficiently. The raw material of the lifting rope R may be any type such as steel, synthetic resin, and plant fiber.

In order to prevent the outer wall panel P from falling from the lifting rope R by a crane or the like during transportation, the side surface portion 41 of the operation plate 4 is pulled out for the purpose of preventing the support tool 3 from coming off from the insertion hole 23. A prevention mechanism 5 is provided. The pull-out prevention mechanism 5 in this embodiment is a recess 45 formed in the side surface portion 42 of the operation plate 4, and the length of the recess 45 is slightly longer than the length of the receiver 2 in the lateral width direction. By the way, when the operation plate 4 rotates about the support shaft 3 due to the weight of the operation plate 4 during transportation, the lower end portion of the receiver 2 fits inside the recess 45, and as a result, the receiver The relative movement of the support 3 with respect to the support 3 is restricted, and the pull-out prevention mechanism 5 operates. The pull-out prevention mechanism 5 is not limited to this embodiment, and is not limited to the configuration as long as it produces substantially the same effect.

Furthermore, the distance L between the side surface portion 41 parallel to the support tool 3 is set to be substantially the same as the distance between the outer peripheral end of the insertion hole 23 and the edge of the receiver 2 on the operation plate 4 side. By doing so, the operation plate 4 prevents the support 3 from being inserted into the insertion hole 23 when it is not formed at a right angle to the receiver 2, so that the disconnection prevention mechanism 5 operates safely. Further, on the rear end side of the support 3, the distance from the side surface portion 41 is made narrower than the distance L to prevent excessive thrusting. Further, as shown in FIG. 7, a protruding portion 46 having a length longer than the thickness of a finger is provided on the surface of the operation plate 4 as needed, and the operation plate 4 is centered on the support 3 during operation. Safety measures have been taken to prevent the fingers from being pressed and injured even if the receiver rotates unexpectedly in two directions.

The use of the hanger 1 (see FIGS. 1 to 3) of the first embodiment of the embodiment of the present invention having the above configuration will be described in order. Insert the receiver 2 fixed to the tip from the opening at one end of the uppermost stage of the outer wall panel P (see FIG. 12) which is transported to the construction site and laminated to show a plurality of hollow holes S from one end. The end of the receiver 2 is pushed in until it protrudes from the other end opening (see FIG. 13). Since the inner peripheral surface of the hollow hole S is uneven, the receiver 2 may be caught in the middle of insertion and the receiver 2 may not move forward, but the lifting rope that fixes the receiver 2 at the tip at hand. By rotating R left and right, the catch can be easily eliminated. Since the round washer 22a is used, this left-right rotation can be smoothly performed with good slippage.

Then, with the operation plate 4 fixing the bent portion of the rear end portion of the support tool 3 shown in FIG. 2 with the tip protruding from the opening at the other end, the tip end portion of the support tool 3 is inserted into the insertion hole 23. Insert it all the way. At this time, when the operation plate 4 does not have a right angle with respect to the receiver 2, it cannot be inserted due to the above-mentioned reason. In this state, the side surface of the receiver 2 faces the recess 45 formed in the side surface portion 41 forming the pull-out prevention mechanism 5, and the operation plate 4 is supported by its own weight at the same time when the operator releases his / her hand from the operation plate 4. Rotating around the tool 3, the lower side surface of the receiver 2 enters between the recesses 45, and the axial movement of the support 3 with respect to the receiver 2 is prevented (see FIG. 4). Therefore, the support 3 fixed to the operation plate 4 also rotates in the insertion hole 23 of the receiving portion 2 but does not move in the axial direction, so that the support 3 does not come out of the insertion hole 23 and is safe. Is. The mechanism 5 for preventing the support tool 3 from coming out of the insertion hole 23 is not limited to this embodiment, and may be by other means. When the protrusion 46 for preventing hand pinching is provided on the surface of the operation plate 4, the protrusion 46 is formed even when the operation plate 4 rotates in the two directions of the receiver during work while holding the operation plate 4. Is safe because it creates a gap between the operation plate 4 and the side surface of the receiver 2.

By performing such attachment work of the receiver 2 to the hollow hole S on both sides of the outer wall panel P in the surface direction and attaching the receiver 2 at two places with one outer wall panel P, two pieces protruding from one end opening. Tie the tip of the lifting rope R, hook it on a hook such as a crane (not shown), and gradually lift it (see FIG. 14). As a result, the tip side of the outer wall panel P is lifted, and at the same time, the load of the outer wall panel P is transmitted from the partition member P1 to the support tool 3, and the support tool 3 is used from the two side plates 22 to the hanging shaft 24, the hanging portion 25, and for lifting. It is lifted by a crane or the like through the rope R. Further, since the operation plate 4 is rotated so as to prevent the support 3 from rotating due to its own weight so as to be in close contact with the recess 45 of the prevention mechanism 5, it can be prevented from coming out further and the safety of the work during transportation can be maintained.

Then, as shown in FIG. 15, the outer wall panel P is lifted in the vertical direction and transported to a predetermined construction position by a crane or the like. If the support 3 is a cylinder as in this embodiment, the partition member P1 of the outer wall panel P is supported only at two points of line contact, but the cross-sectional shape of the support 3 is a polygonal shape. If this is done, the contact surface will be formed, so that the friction between the partition member P1 and the contact surface will be large and the partition member P1 will be more stable. In this case, since the support 3 does not rotate in the insertion hole 23, a different type of pull-out prevention mechanism 5 is required.

When the crane is transported to a predetermined position, as shown in FIG. 10, the stepped surface 26a of the stepped portion 26 formed on the receiver 2 is the outer wall panel P whose installation has already been completed on the upper surface or the lower side of the foundation base. While operating the crane or the like so that it is placed above the outer wall receiving metal fitting G placed on the upper surface K, the operator grasps the operation plate 4 by hand and guides it while suspending it. At the time of being suspended, the load of the outer wall panel P is transferred from the support 3 to the outer wall receiving metal fitting G, so that the support 2 is free and can be easily pulled out from the insertion hole 23 in the surface direction of the outer wall panel P. .. As shown in FIG. 16, this pulling out is performed after the operator manually rotates the operation plate 4 to a position perpendicular to the receiver 2 to escape from the recess 45 and release the pull-out prevention mechanism 5. The work is easy because you only have to do it. Further, since a clearance corresponding to the height of the outer wall receiving metal fitting G is formed above the upper surface K in the pulling direction, there is no obstacle in pulling out. In FIG. 10, H is an upright maintenance tool for the outer wall panel P provided on the outer wall receiving metal fitting G, whereby the outer wall panel P is supported so as not to fall even if the hanging tool 1 is removed.

After the above work is completed, the lifting rope R is lifted by a crane or the like, and the receiver 3 of the hanging tool 1 below the hollow hole S is pulled out from the upper opening to finish the work. Such work is performed for each outer wall panel P, and the outer wall of the building is constructed in order from the bottom.

As is clear from the above description, when the hanger 1 of the present invention is used, the attachment / detachment of the receiver 2 from the support 3 on which the load of the outer wall panel P is placed can be attached / detached in the surface direction of the outer wall panel P, that is, the outer wall. Since the direction is orthogonal to the thickness direction of the panel P, there is an advantage that the difficulty and danger of work due to the use of bur, which has been possessed by the prior art, can be eliminated.

The present invention can be used extremely effectively for construction work in which an outer wall panel with a hollow hole is attached to a building, and can improve work efficiency and eliminate the risk of work. I'm sure it's an invention.
