Description

[Detailed Description of the Invention] [Industrial application] The present invention relates to a form guide device in an assembly mechanism of a two-part form, and in particular, an upper and lower form for molding concrete columns. The present invention relates to a form guide device in the assembly mechanism.

[Prior Art] Conventionally, when assembling a formwork for concrete pillar molding, first, the lower formwork is placed at a predetermined position with a lower formwork hacker provided on an I-beam of a crane. The upper mold is suspended and lowered by a hacker of the upper mold so as to be brought into contact with the joint surface of the lower mold, and workers are arranged on both sides in the longitudinal direction of the mold. An operator signaled the crane operator to pull out the joint bolt of the upper formwork, insert a Shino into this, and pass it through the nut hole of the lower formwork to join the upper and lower formwork.

[Problems to be solved by the invention] Assembling of the above-mentioned conventional formwork is done by hand by a signal between an operator and a crane operator, which is extremely dangerous in terms of work. After joining the upper and lower molds, a concrete mold release agent is applied, but if the joint is not perfect, the mold release agent scatters from the gap and deteriorates the surrounding environment. Occurs. Therefore, there is a technical problem to be solved in order to surely and smoothly perform the work of aligning the upper and lower molds with each other without manpower required for the work of aligning the upper and lower molds. , It aims at solving the said subject.

[Means for Solving the Problems] The present invention has been proposed in order to achieve the above-mentioned object. Brackets are provided on both sides of a base frame of a crane or the like, and a link mechanism is provided above and below an outer portion of the bracket. The mold guide pieces are provided so as to face each other, and the air cylinder is interposed between an inner middle portion of the mold guide piece and an air cylinder mounting piece fixed to the base frame. An object of the present invention is to provide a form guide device in an assembly mechanism of a two-part form.

[Operation] In this invention, the base frame is, for example, an I-beam of a crane, brackets are provided on both sides of the I-beam, and
Formwork guide pieces are vertically provided facing the upper and lower outer surfaces of the bracket via a link mechanism. Further, since the air cylinder is interposed between the substantially middle portion of the mold guide piece and the air cylinder mounting piece fixed to the I-beam, the upper mold is held by the upper mold hacker while holding the tire portion. It is hung, and then the mold guide pieces are brought into contact with both side surfaces of the end face of the mating portion of the upper mold and lowered. Then, when the both side surfaces of the mating portion are brought into contact with each other by the mold frame guide pieces, by operating the air cylinder, the mold is guided through the link mechanism that vertically extends the mold guide. Since the distance between the frame guide pieces can be freely adjusted, the corresponding contact operation can be performed very easily. In this way, the upper formwork suspended by the upper formwork hacker and descending reaches the upper face of the lower formwork which is previously fixed with the mating portion as the upper face. At this time, the mold guide pieces, which are in contact with both side surfaces of the mating portion of the upper mold, slide against the side surfaces of the mating portion of the lower mold to come into contact with each other. In that case, the mold guide pieces will join the upper and lower molds in an orderly manner. Thus, the work of assembling the upper and lower molds can be done very easily and reliably without any danger.

[Embodiment] An embodiment of the present invention will be described below in detail with reference to the attached drawings. For the sake of convenience of description, the configurations and operations that are conventionally known will be described at the same time. In FIG. 3, (1) is the I-beam of the crane. Upper frame hackers (2) (2) ... Are attached to the I-beam (1) at a predetermined interval. Further, a required number of the upper mold hackers (2) (2) ... Abut on the upper surfaces of the tire portions (4) (4) ...
(2) Restricting pieces (2a), (2a), which restrict the descending position of (2), are provided. This upper formwork hacker (2) (2) ... is the upper formwork
(3) Tire part (4) (4) ...
a) (4a) ... is hooked to suspend the upper formwork (3). Further, (3a) is a lower mold, and the lower mold (3a) is attached to the lower mold hacker (5) provided on the I-beam.
The collar portion (6a) forming the mating surface of (a) is hooked and placed at a predetermined position such as a trolley (T). Therefore, the upper mold (3) is also provided with a flange (6a) to be brought into contact with the flange (6a) of the lower mold (3a). Furthermore, after the upper and lower flanges (6) (6a) are joined together, bolt holes (not shown) that are respectively opened in the flanges (6) (6a) of the husband etc. A bolt (not shown) is inserted into and fastened to form a concrete pillar formwork.

Then, brackets (7) and (7) are fixedly installed on both sides of the I-beam (1). Then, one ends of the parallel link pieces (8), (8), (8), (8) are pivotally attached to the upper and lower ends of the brackets (7), (7), respectively.
In addition, the parallel link pieces (8), (8), (8), (8) are vertically pivoted at the upper and lower parts of the formwork guide pieces (9), (9), which are to be hung vertically. To wear. Furthermore, this formwork guide piece (9) (9)
Are extended downward, and taper surfaces (9a) (9a) are provided at the lower ends thereof, which are obliquely outwardly inclined. Also, mounting pieces (11) (11) (11) (11) (11) (11) of the air cylinders (10) (10) fixedly provided on the inner side of the substantially middle portion of the mold guide pieces (9) (9) and the lower portion of the I-beam (1). )
The tip ends of the air cylinders (10) (10) are pivotally mounted and interposed therebetween. Incidentally, in detail, this air cylinder (1
One end of 0) (10) is pivotally attached to the mounting pieces (11) (11) (11),
And the piston (10a) (10a) of the air cylinder (10) (10)
The I-beam by pivotally attaching the tip of the to the formwork guide pieces (9) (9)
The distance between the mold guide pieces (9) and (9) centering around (1) is adjusted by the protrusion and retraction of the pistons (10a) and (10a) of the air cylinders (10) and (10). Further, the lower portion of the air cylinder (10) (10) mounting portion of the mold frame guide pieces (9) (9) is extended downward as described above, but the length thereof is the upper mold frame ( It only needs to be able to hold 3). Further, the formwork guide piece (9) described above.
The distance between (9) is adjusted according to the size of the upper and lower molds (3) and (3a), but the upper mold hacker (2) (2) ... (4) When the projecting edges (4a) (4a) of the ends of (4) (4) are clamped and hung, the upper mold is held at the lower inner part of the mold guide pieces (9) (9). The frame (3) is embraced, and the taper surfaces (9a) (9a) of the frame guide pieces (9) (9) are attached to the outer surface of the flange (6) of the upper mold (3). When the perpendicular surface of the portion directly above the abutment contacts, the upper formwork (3) is lowered onto the upper surface of the lower formwork (3a). At this time, as described above, the lower mold (3a) is placed in a horizontal state with the flange portion (6a) being the upper surface. Therefore, the upper formwork (3) that should be brought into contact with the collar part (6a) of the lower formwork (3a) also has the flange part (6) on the lower surface and descends in a horizontal state. As a matter of course, it is joined to the flange portion (6a) of the lower mold (3a).

Thus, when the upper formwork (3) is lowered by suspending the upper formwork hackers (2) (2) ... and reaches the upper surface of the collar part (6a) of the lower formwork (3a), The taper surfaces (9a) (9a) at the lower end of the mold guide pieces (9) (9) holding the upper mold (3) from the outer surface are
Since it comes in contact with the outer surface of the collar portion (6a) of (3a) and descends, it comes into contact with the portion directly above the tapered surfaces (9a), (9a). Upper formwork
The collar part (6) of (3) is in contact with the lower mold part (3a) in conformity with the collar part (6a). After that, the mold release agent is applied to the inside of the formwork and the flanges (6) and (6a) are bolted, but the work of aligning the upper and lower formwork (3) and (3a) is the operation of the crane. This can be done by only the person concerned, eliminating the conventional danger and preventing the release agent from scattering from the joint.

It should be noted that the present invention should not be limited to the above embodiment,
Various modifications can be made without departing from the spirit of the invention, and it goes without saying that the invention covers the modifications.

[Effects of the Invention] As described in detail in the above-described one embodiment, the invention is such that the frame guide pieces are vertically erected vertically on both sides of a base frame of a crane or the like by a link mechanism, and Since the air cylinders are respectively installed in the intermediate portions, the form guide pieces can be adjusted vertically while maintaining the parallel state.
Can be adapted to each size of formwork. Therefore, the lower formwork is
The upper mold is suspended from the upper surface of the lower mold by being placed in a predetermined position, and the upper mold is lowered, but the flanges on both sides of the upper mold are used as mold guide pieces. It descends while being held. Then, when it reaches the flange of the lower mold, the tapered surface of the mold guide piece comes into contact with the outer surface of the flange of the lower mold and descends, and the perpendicular portion of the mold guide piece. The collar portion of the lower formwork comes into the inner surface of the, so that the collar portion of the upper formwork and the flange portion of the lower formwork automatically coincide with each other.

Therefore, in order to make the collars of the upper and lower molds coincide with each other as in the conventional case, it is not necessary for the crane operator to make an adjustment by sending a signal to the operators at the stationary parts at both ends of the lower mold. This eliminates the risk and ensures that the seams of the upper and lower molds match, so there is no chance that the concrete mold release agent applied to the inner surface of the mold will scatter outside and pollute the surrounding environment. Of. In this way, the work environment and workability are improved, and the work of aligning the upper and lower molds can be performed quickly and reliably.
