Description

  The present invention relates to a mold for forming a concrete product having a groove-like recess on a side surface.

  Conventionally, a mold for molding a concrete product with uneven side surfaces has a horizontal guide attached to the lower part of the side frame, and this horizontal guide is supported by a roller that is pivotally attached to the base 1 so that the side frame can be used when assembling. Uses technology to move the abutment to the surface plate side, move the side frame away from the surface plate when releasing the mold, and clean the molding surface of the side frame or apply a release agent. ing. (For example, see Patent Document 1)

However, as described above, when the product is an H-shaped sheet pile that requires a groove-shaped recess on the side surface only by separating the side frame from the surface plate during mold separation, the upper half side of the molding surface of the side frame is a cleaning or peeling material. The lower half is in a state where the lower half has to be cleaned and the release material must be applied by hand, and even if it takes a lot of work, cleaning and application are likely to be incomplete. By moving the side frame to another work place and facing downward so that the molding surface faces the operator, complete molding surface cleaning and release agent application can be performed. However, it takes a considerable amount of time to move and return the side frame, and there is a problem that it is necessary to secure a device to be moved and a place for the side frame.

A molding space 5 as shown in FIG. 1 is formed by the end frames 4 and 4 arranged so as to be closed, and concrete is cast into the molding space 5 as shown in FIG.

  When the product 6 is an H-shaped sheet pile as shown in FIGS. 1 and 8, the side frames 3 and 3 form groove-like recesses 7 and 7 as shown in FIG. 8 on both sides of the product 6. From this, it is formed into a groove shape that fits into the recesses 7 and 7 so that there are spaces 8 and 8 inside, and edges 9 and 9 are provided above and below the openings of the spaces 8 and 8, respectively. Reinforcing frames 10 and 10 are provided outside the edges 9 and 9. The side frames 3 and 3 are divided and formed in, for example, one section 3m along the section line E1 shown in FIG. 5 so that movement and change of posture can be performed individually or in conjunction.

  1 to 4, reference numerals 11 and 11 denote support arms that support the side frames 3 and 3. The support arms 11, 11 are inserted into the spaces 8, 8 of the side frames 3, 3 from the opening side so that the tip reaches the middle of the spaces 8, 8, and the pivots 12, 12 extending in the longitudinal direction at the tip. Attaching portions 13 and 13 that are attached to the advancing / retreating platform, which will be described later, are continuously provided on the lower side.

  In the figure, reference numerals 14 and 14 denote reinforcing ribs attached at predetermined intervals in the spaces 8 and 8 of the side frames 3 and 3. The reinforcing ribs 14 and 14 are attached to the bearings 15 and 15 as pivot centers at positions shifted from the center of gravity of the side frames 3 and 3 as shown in FIGS. By fitting the pivots 12 and 12 supported by the support arms 11 and 11, the side frames 3 and 3 are rotated around the pivots 12 and 12, and the horizontal molding posture shown in FIG. The downward preparation posture shown in Fig. 2 can be taken.

  In this figure, reference numerals 16 and 16 indicate the state in which the side frames 3 and 3 are prevented from rotating when the measurement frames 3 and 3 take the mold assembly posture or the preparation posture by the rotation about the pivots 12 and 12, respectively. The stop member to be held in When the side frames 3 and 3 take the assembling posture using the U-shaped members as shown in FIGS. 1 to 3, 6 and 7, the restraining members 16 and 16 are illustrated with the lower end on the back side. 1. When contacting the front ends of the support arms 11, 11 as shown in FIG. 2 and taking a preparation posture, go to the reinforcing ribs 14, 14 so that the entire back surface rides on the upper surface of the support arms 11, 11 as shown in FIG. It is fixed.

In the figure, reference numerals 17 and 17 denote a moving base that is attached to and supported by the support arms 11 and 11. The movable bases 17 and 17 fix the mounting portions 13 and 13 of the support arms 11 and 11 to the upper side of the outer ends, and a pair of wheels 18 and 18 are attached to the side surfaces at appropriate intervals. The guide 19 extended from the said base part 1 to the preparation position side of the side frames 3 and 3.
, 19 to roll. Accordingly, the movable bases 17 and 17 can be easily moved forward and backward by the rolling of the wheels 18 and 18 so that the side frames 3 and 3 can be positioned at the mold assembly position and the preparation position.

  In FIG. 8, reference numerals 20 and 20 denote joint notches formed alternately at the left end and the right end of the product 5. The joint notches 20 and 20 are configured so that when the products 6 are joined in parallel, as shown in a part in the circle of FIG. By inserting L-shaped metal fittings 21 and 21 conforming to the shape of the joint notches 20 and 20, prevention of damage at the time of joining or the like is achieved.

  The L-shaped metal fittings 21 and 21 are supported by the joining notch forming portions 22 and 22 provided in the side frame 3 so as not to be displaced or detached when the product is molded. When detaching 3 and 3, it must be easily detached from the joint notch forming portions 22 and 22. For this reason, the L-shaped metal fittings 21 and 21 are attached by attaching the L-shaped metal fittings 21 to the bonding notch forming portion 22 provided on the side frame 3 as shown in FIG. The deformed leg pin 24 shown in FIG. 5 or the split pin 25 shown in the circle of FIG. 5 is inserted into the through hole 23 formed in the forming portion 22 so that the product is detached when the product is removed.

  1-4, FIG. 6, and FIG. 7, the code | symbols 26 and 26 show the junction part at the time of forming the side frames 3 and 3 into 2 parts vertically. The joints 26 and 26 are formed at the groove bottom portions of the side frames 3 and 3 so as to be parallel to the longitudinal axis, and a spacer 26 having a different height is sandwiched between the joints 26 and 26. Thus, by joining the joints 26 and 26 with the bolts 28, several types of side frames 3 and 3 having different heights in the same side frames 3 and 3 can be obtained. When the height of the side frame 3 is changed in this way, the height of the wife frame 4 must be changed accordingly, but the height of the side frame 3 set by the spacer 26 is the maximum of the side frame 3. If it is placed according to the dimensions, it is not necessary to change the wife frame 4, which is convenient.

  1 to 3, 6, and 7, reference numerals 29 and 29 denote operation fittings for moving the measurement frames 3 and 3 with a crane or the like. The operation fittings 29 and 29 are formed in a U-shape, and the lower pieces 29 a and 29 a are attached across the reinforcing member 9 and the side frame 3, and the upper pieces 29 b and 29 b are extended to above the center portion of the side frame 3. The hole 30, 30 is opened at the tip. Then, by hanging a hook (not shown) attached to a lame rope such as a crane to the holes 30 and 30 and coasting in a direction approaching or separating from the bottom board 2, the advancing and retreating movement of the measurement frames 3 and 3 and the mold assembly are performed. The conversion between the posture and the preparation posture is performed.

  6 and 7, reference numeral 31 indicates an operation grip for moving the measurement frame 3 manually. Since this operation grip 31 is attached to the reinforcing rib 13 attached to the measurement frame 3 with the attachment material 32 and exists in the opening of the side frame 3, the side handle 3 approaches the bottom panel 2 with this operation grip 31. It can be moved in the direction or away.

  As shown in FIG. 1, the molding form A of the concrete product having the above configuration moves the side frames 3 and 3 to the bottom plate 2 side in the horizontal orientation, and the lower reinforcing material 9 contacts the side surface of the bottom plate 2. In this state, if the mold assembly is formed in which both ends of the side frames 3 and 3 are closed by the end frames 4 and 4 as shown in FIG. 5, a molding space 5 as shown in FIG. Is formed. Therefore, when concrete is placed in the forming space 5, a product 6 as shown in FIG. 2 is formed.

  When the product 6 formed as described above can be demolded by hardening of the concrete, the side frame 3 and the side 3 are unfastened, and the crane of a lame line such as a crane not shown in the drawing is attached to the operation fitting 29. If it is hung and made to coast toward the preparation position of the side frames 3 and 3, the moving stand 17 will move by rolling of the wheel 18, and the side frame 3 will be located in a preparation position as shown in FIG.

  When the side frame 3 is positioned at the preparation position, when the operation fitting 29 is further pulled in the direction of an arrow or the direction, the side frame 3 is turned around the pivot 12 so that the opening is directed downward. When this is done, the restraining member 16 rides on the upper surface of the support arm 11 as shown in FIG. 4 and holds the side frame 3 in this state so that the preparation posture is taken.

  As described above, when the side frame 3 takes the preparation posture, all the molding surfaces of the side frame 3 face the operator, and the bearing 15 of the pivot 12 provided on the side frame 3 is on the side. If it is shifted below the center of gravity of the frame 3, the space between the side frame 3 and the product can be widened, and the work within this space can be performed. Accordingly, it is easy to clean the molding surface of the side frame 3 and to apply the release medicine without any unevenness, and to the joint notch 21 provided in the side frame 3 as shown in FIG. Alternatively, the work of attaching the L-shaped bracket 21 with the split pin 25 or the like can be easily and reliably performed.

  When the preparation of the side frame 3 is completed as described above, the side frame 3 is centered on the pivot 12 when a hole of a lame rope such as a crane not shown in the drawing is put in the hole 30 of the operation fitting 29 and pulled upward. At the same time, the restraining member 16 engages with the front end surface of the support arm 11 to stop the rotation and holds the mold assembly posture. Therefore, if the operation fitting 29 is swung toward the mold assembly position in this state, the side frame 3 reaches the mold assembly position as shown in FIG. Therefore, if both ends are closed with the end frame 4, the mold A having the molding space 5 can be easily formed.

  In addition, when it is necessary to change the height of the side frame 3, the mold A of the present invention separates the joint portions 26 and 26 and has a dimension shown in FIG. 7 between the joint portions 26 and 26. If the spacers 27 or the spacers 27 having the dimensions shown in FIG. 8 are sandwiched between the joints 26 and 26 and the bolts 27, the height of the same side frame 3 varies as shown in FIG. 7 and FIG. Various types of side frames 3 can be obtained.

  The molding form of the concrete product according to the present invention is suitable for manufacturing an H-shaped concrete sheet pile that performs revetment, earth retaining, and the like.
