Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a frame for carrying a reinforcing wire mesh such as a metal lath or a wire lath, which is used by being embedded in a thin lightweight cellular concrete panel, in a predetermined aligned state.

[0002]

2. Description of the Related Art Conventionally, in order to simultaneously manufacture a large number of lightweight cellular concrete panels in which a reinforcing wire net is contained in one form, a predetermined number of reinforcing wire nets are set upright in one form. It was necessary to align and arrange at the intervals of. In this way, the work of arranging a large number of reinforcing wire nets in the mold is not arranged one by one, but the work efficiency is increased if a large number of reinforcing wire nets can be arranged at one time. Therefore, Japanese Patent Application Laid-Open No. 58-20810 proposes a device for arranging a large number of reinforcing wire nets at one time. In the device disclosed in Japanese Patent Laid-Open No. 58-20810, comb teeth having a tapered surface at the tip are planted side by side in parallel with each other in a frame body at a predetermined interval to form a comb tooth row. Using a reinforcing wire mesh aligning device and a reinforcing wire mesh holding device in which several rows of comb teeth are provided at desired mutual intervals,
A large number of reinforcing wire meshes are once laid by lifting the reinforcing wire meshes aligned on the reinforcing wire mesh aligning device with the reinforcing wire mesh holding device in the arrayed state and disposing the reinforcing wire mesh holding device in the formwork. It is a device that can be placed in.

[0003]

However, Japanese Unexamined Patent Application Publication No. Sho 5
The reinforcing wire mesh aligning device disclosed in Japanese Unexamined Patent Application Publication No. 8-20810 is a device that simply erects and aligns the reinforcing wire mesh at predetermined intervals, and this device grips the reinforcing wire mesh and The function to open it was not added. On the other hand, the reinforcing wire net holding device disclosed in Japanese Patent Laid-Open No. 58-20810 holds the reinforcing wire nets aligned by the reinforcing wire net aligning device, and disposes the reinforcing wire nets in the mold while holding the reinforcing wire nets. A large number of inverted U-shaped rods are used in the device, and a large number of rods are provided between the rods so that the reinforcing wire mesh can be clamped without dropping. A rod having a special shape for inserting and connecting the lower end of the rod is required, and the rod having this special shape has auxiliary means for connecting it to the main frame of the reinforcing wire mesh holding device. It is required on both ends of the rod. Further, this specially shaped rod is placed at the bottom of the mold when the reinforcing wire mesh is placed in the mold, and when the lightweight cellular concrete raw material slurry is placed in the mold and a predetermined hardness is reached, Since a large number of bar-shaped members bent in an inverted U shape are separated from the bar having the special shape and pulled up, it is necessary that the bar having the special shape has a shape that enables this separation work. It was In addition, this special shaped rod remains in the mold even after the lightweight cellular concrete raw material slurry has hardened, and after the lightweight cellular concrete raw material slurry has sufficiently hardened, the special shaped rod is collected. Then, it had to be used again in the reinforcing wire mesh holding device. As described above, there is a drawback that a rod-shaped body having a special shape necessary for the recovery work is required. As mentioned above,
The device disclosed in Japanese Patent Laid-Open No. 58-20810 uses a formwork that has been used in the related art, in which a large number of rod-shaped members bent in an inverted U shape are inserted into a bottom plate of the formwork and holes are formed for making them upright. However, there is a drawback in that a rod having a special shape and a device having a complicated structure for holding the reinforcing wire net in the mold are required. On top of that, as mentioned above,
Auxiliary means are required at both ends of the special shaped rod,
This auxiliary means also has a disadvantage that the lightweight cellular concrete raw material slurry is poured in a wasteful manner by the space because the lightweight cellular concrete raw material slurry is placed in the mold. An object of the present invention is to use a lightweight and aerated concrete raw material slurry in a mold without using a new and complicated device disclosed in Japanese Patent Laid-Open No. 58-20810 in a mold. Even if the device that is in contact with the lightweight cellular concrete raw material slurry is the same as it used to be, it is possible to arrange multiple reinforcing wire nets upright in a single formwork in an aligned state. It is to provide a reinforced wire mesh carrier frame.

[0004]

The apparatus is characterized in that a plurality of rows are provided at desired mutual intervals, and a mechanism for releasably gripping the reinforcing wire mesh inserted between the comb teeth is provided in the frame main body. In a more preferable embodiment as a mechanism for releasably gripping the reinforcing wire mesh inserted between the comb teeth planted in the frame main body, the gripping member constituting the gripping mechanism is always biased in the closing direction. The device is configured to hold the reinforcing wire mesh and has a mechanism in which the reinforcing wire mesh is released from the gripped state only when the gripping member is moved in the opening direction against the urging force thereof.

[0005]

According to the present invention, the "comb teeth of the reinforced wire mesh carrying frame in the aligned state of the present invention are erected side by side on the frame body at predetermined intervals to form comb teeth rows, and the comb teeth rows are arranged at desired mutual intervals. The "structure provided in several rows" means that when the frame main body is on the lower side and the tips of the comb teeth are on the upper side, the reinforcing wire netting is provided at predetermined intervals between the adjacent comb teeth. It plays the role of placing them upright and aligned. In addition, "a mechanism that releasably grips the reinforcing wire mesh inserted between the comb teeth"
Even when the frame body is on the upper side and the tips of the comb teeth are on the lower side, that is, when the reinforcing wire mesh is aligned and arranged on the frame body, the comb is turned upside down. It plays the role of holding the reinforcing wire mesh arranged in an aligned state between the teeth without dropping, and the reinforcing wire mesh transport frame is brought upside down on the formwork for placing the lightweight cellular concrete raw material, A mechanism that releasably grips the reinforcing wire mesh when the wire is lowered to a predetermined height in the mold, releases the gripping state of the reinforcing wire mesh, and drops the reinforcing wire mesh into the mold in the aligned state. Play a role. This is a preferred embodiment as a mechanism for releasably gripping the reinforcing wire mesh inserted between the comb teeth. "The gripping member constituting the gripping mechanism is normally biased in the closing direction to grip the reinforcing wire mesh. When the mechanism for releasing the reinforcing wire net from the gripping state is released only when the gripping member is moved in the opening direction against the urging force, the reinforcing wire mesh is not moved unless the gripping member is moved in the opening direction. It shows the effect that the reinforcing wire netting is not detached from the frame body and dropped even if it is held by the frame body and the frame is turned upside down.

That is, comb teeth are erected in parallel on the frame body at predetermined intervals to form comb teeth rows, and the comb teeth rows are provided at a desired mutual interval and are inserted between the comb teeth. It is a reinforcing wire mesh carrying frame in which a frame body is provided with a mechanism for releasably gripping the reinforcing wire mesh.

This will be described in detail with reference to FIGS. 1 and 10. The frame main body has a structure in which the vertically long boards (38) (39) and the horizontal boards (40) are assembled in a rectangular shape and has a bottom plate. Comb teeth (13) are erected at predetermined intervals P in the direction, and in the lateral direction at intervals where the wire mesh (a) can be inserted. The vertically elongated cauldron (38) has a channel-shaped cross section and forms the above-mentioned hooks (27) (28). As shown in FIGS. 3 and 4, the structure of each comb tooth is formed by obliquely forming the tip of a square pipe (41) and welding a flat steel (42) thereto.
The flat steel (42) has a triangular shape when viewed from the front and has a sharp tip. As described above, the flat rope (42) has the tapered surface (42a) formed at its tip and the tapered surface (42b) inclined rearward. The tapered surface (42a) serves as a guide for facilitating accurate insertion of the reinforcing wire mesh between the comb teeth when the comb teeth (13a) face upward.

The specific structure of the main body of the wire net gripping device (b) is shown in FIG.
As shown in FIG. 6, it consists of a rubber pad (45) provided on the rope (43) and a nail (46) provided on the rope (44), and the rope (43) (44) is a frame. It is slidably mounted between the vertical rails (38) and (39) of the main body so as to be slidable in the directions opposite to the horizontal rails (40). The rubber pad (45) and the nail (46) form a wire mesh ( It is provided at a position where both the left and right sides of a) can be gripped. In the example shown in FIG. 1, it is provided at eight locations.

Then, the rubber pad (45) of the square rope (43)
There are springs (51) (52) that constantly bias in the gripping direction to grip the wire mesh with the nail (46) of the square steel (44). This spring (51) (52) is the receiving (60) (59) of square steel (43) (44)
And the vertical bars (38) (39) of the frame (12). The shaft (61) traversing the square steel (43) (44) has the rod (53), and the pin (56) shown in FIG. 5 engaging with the slit groove (54) at the end of the rod (53) has a cylinder. It is provided on a slider (57) that operates with (58).
When the rod (53) is not pushed by the cylinder (58) (when the cylinder (58) shown by the solid line in FIG. 5 is not in operation), the rubber pad (45) of the angle rope (43) and the angle rope It is in close proximity to the nail (46) of (44). As described above, the wire net gripping device (b), which is a mechanism for releasably gripping the metal rope, is configured to be constantly held in the gripped state by the springs (51) and (52) and to be in the grip released state only while the cylinder is in operation. ing. The cylinder (58) is a grip release cylinder provided in the device (15) for pitch-moving the movable carriage (14) shown in FIG.

When the cylinder (58) operates and the slider (57) moves to the right in FIG. 5, the rod (53) rotates clockwise and the cams (47) (4) pass through the shaft (61).

And the receiver (50) is attached to the square steel (44), and the cams (47) (48) are attached to the shaft (61) 18
Since they are installed in a state of 0 ° phase shift, the receiver (49) is moved to the left and the receiver (5) against the springs (51) (52).
Move (0) to the right to separate the rubber pad (45) and the nail (46) left and right. The rubber pad (45) is square steel (43).
It straddles between (44) but is fixed only to the square steel (43). When the gripping device (b) is released from the gripping state as described above, at the wire netting insertion position, the wire meshing preparation state is prepared between the comb teeth of the transport frame (13), and the gripping device (b) grips. When the state is reached, it becomes possible to descend to a position where the inserted wire net can be held. Further, when the carrying frame (13) having the inserted wire mesh in the aligned state is carried, the gripping device (b) is in the gripping state and grips the wire mesh. When the transportation frame (13) is lowered to a predetermined height when it arrives at the formwork (36) into which the wire net should be put, for example, a device (15) for pitch-feeding the above-mentioned movable carriage (14) provided on the formwork. The holding device (b) is brought into a released state by a holding release cylinder similar to that attached to the wire box (a), and the wire net (a) can be put between the transport frame (13) and the setting rod of the form (36). As described above, when the wire mesh (a) is put into the form (36) from the carrying frame (13), there is a tapered surface (42b) behind the comb teeth (13) as shown in FIG. , The comb teeth (13) descend while guiding the set rod (35). Therefore, even if there is a slightly bent sideways set bar (35), it prevents the comb teeth (13) from being lowered, so that the wire mesh (a) is correctly straightened between the set bars (35). Can be inserted into.

The wire mesh transport frame (13) is moved by the pitch feeder (15) by the pitch of the comb teeth at the wire mesh insertion position. Repeating the above operation, after inserting the wire net for one type of wire net transport frame, the transport frame (13) becomes the gripper crane (19).
Is lifted from the moving carriage (12), the pitch feed device (15) is returned to the origin by the driving device, the next transport frame is placed on the moving carriage, and the wire netting work is performed. Further, as shown in FIG. 12, when there are two wire netting devices, the wire netting device for which the first row loading operation is completed is moved to the second row loading position by the lateral movement drive device (2),
The loading device in the third row is moved to the fourth row to perform loading, and the transport frame shown in FIG. 12 has four rows of wire nets installed in the longitudinal direction.

[0018]

According to the carrying frame of the present invention, not only can the reinforcing wire netting be arranged at predetermined intervals between the comb teeth on the frame, but also the reinforcing wire netting inserted between the comb teeth can be released. Since a mechanism for gripping is provided, it is possible to prevent the reinforcing wire mesh from falling off the transportation frame even if the transportation frame is in the inverted state, and if necessary, drop the reinforcing wire mesh from the inverted frame. Also, it is possible to transfer the reinforcing wire mesh to the formwork in an aligned state. Further, when a taper is provided on the back of the comb teeth, when the reinforcing wire net is transferred from the carrying frame of the present invention to the mold, the set bar of the frame does not hinder the descending of the comb teeth, and conversely. Since the comb teeth have a taper and play a role of guides, it is possible to align the set rods that are erected in the formwork with these comb teeth, and set the reinforcing wire mesh between the set rods of the formwork in a straight state. It has the effect of being able to. Furthermore, a preferred embodiment as a mechanism for releasably gripping the reinforcing wire mesh inserted between the comb teeth is that "the gripping member constituting the gripping mechanism is normally biased in the closing direction to grip the reinforcing wire mesh. When a mechanism is adopted that the reinforcing wire mesh is released from the gripping state only when the gripping member is moved in the opening direction against the biasing force,
As long as the gripping member is not moved in the opening direction, the reinforcing wire mesh is gripped by the frame body, and even if the frame is turned upside down, the reinforcing wire mesh does not detach from the frame body and drop, so release the grip of the reinforcing wire mesh. Only when loading the reinforcing wire mesh on the first transport frame and when transferring the reinforcing wire mesh from the last transport frame to the formwork, at other times, if the gripping state is maintained without any modification, good. Therefore, when moving or reversing the carrying frame on which the reinforcing wire net is placed, it is possible to maintain the gripped state without adding any hand. "
