Description

Formwork device for manhole block with simple separation structure {MANHOLE BLOCK FOR MOLD DEVICE}

The present invention relates to a formwork device for a manhole block having a simple detachment structure, and more particularly, to install a pillar frame on the base panel, to install the base frame and to rotate the side wall panel on the base frame, and to the side wall panel. It relates to a formwork device for a manhole block having a simple separation structure that is easy to separate the cured concrete block from the formwork by rotating the sidewall panel by connecting the parts to the corner member, and to easily assemble again to cure the concrete block. .

In general, the formwork is a structure temporarily installed in order to make the concrete structure into a predetermined shape and dimensions, generally using a concrete formwork plywood, depending on the construction may use a hard fiber board, synthetic resin, aluminum panels, steel sheets and the like.

These formwork is composed of such a frame to squeeze the shape of the pillar, floor, wall, etc. to pour the concrete, and then pour the concrete and harden it and remove the mold. In the general floor, formwork is removed four weeks after the concrete is poured and two weeks after the roof or roof, and the formwork can be reused. In addition, the criterion for determining the formwork thickness or spacing of the reinforcement depends on the side pressure of the raw concrete acting on the formwork, which depends on the type of concrete. As a formwork, concrete plywood is used as a formwork. Depending on the construction, a hard fiber board, a synthetic resin, an aluminum panel, and a steel sheet may be used.

However, in the case of a concrete structure having a space therein, the formwork should be formed by assembling the formwork again after pouring concrete and then removing the formwork plywood placed on the inner surface of the concrete structure after the worker enters the interior. In the process of removing and assembling formwork, the fixing is delayed and productivity is lowered. In the process of removal, plywood or connecting members may fall, causing serious problems that threaten worker safety.

On the other hand, preferably, the angle panel 72 of the corner member 70 may be configured such that the width of the lower than the width of the upper. For example, as shown in FIGS. 4 and 5, the angle panel 72 may be configured in the form of a right-sided trapezoid having a lateral angle of θ1. Meanwhile, as the side angle of the angle panel 72 is composed of θ1, the side angle of the side wall panel 62 corresponding to the angle panel 72 is composed of θ2, and the sum of θ1 and θ2 is 180 °. Can be.

Subsequently, a cushion member may be further installed on an outer surface of the connection frame 32 to prevent damage due to the impact of the bent portion 621 of the side wall panel 62 being rotated.

6 and 7, the fixing bar 73 and the angle panel 72 of the corner member 70 may have predetermined angles r and s. In addition, the fastening bar 63 may be configured to have a predetermined angle with the side wall panel 62 corresponding to the angle. At this time, the size of the angle (r, s) is the amount so that the corner member 70 can be taken out in the direction of the arrow (F) after releasing the connection between the fastening bar 63 and the fixing bar 73 The fixing bar 73 on the side may have an angle to be parallel, or the distance between the fixing bar 73 on both sides toward the inner side of the formwork device 10 may have an angle. Therefore, the corner member 70 may be easily separated from the formwork device 10 after the concrete curing process.

Referring to the manufacturing process of the concrete block 100 using the formwork device 10 for the manhole block having a simple separation structure configured as described above, first, the corner member 70 in the upper edge portion of the base frame frame 50 After placing upright, the fastening bar 73 of the corner member 70 and the fastening bar 63 of the side wall panel 62 are disposed to be in contact with each other, and then the fastening hole 631 and the fastening hole 731 are connected to each other. By fastening to form the outer wall of the formwork device 10. The outer wall of the formwork device 10 is preferably made so as to prevent leakage of the concrete mortar, and if necessary, a predetermined sealing member may be provided between the members. The formwork device 10 constitutes an inner surface shape of the manhole block.

Subsequently, the outer mold 200 is inserted while covering the formwork device 10, and then concrete mortar is introduced through the inlet of the outer formwork 200 to form a space between the outer surface of the formwork device 10 and the inner surface of the outer formwork 200. After filling the mortar with concrete, it will be cured for a certain time.

Next, after curing the concrete mortar to remove the external formwork 200 and separate the corner member 70 from the side wall panel 62, the side wall panel 60 is rotated to be placed on the connecting frame (32). Then, by separating the concrete mortar from the formwork device 10, the process of manufacturing a series of concrete blocks 100 is completed.

At this time, preferably, the side wall panel 62 may be rotated by separating the corner member 70 from the side wall panel 62, thereby creating a space on the side surface, and thus, may be easily rotated. . For example, the corner member 70 is fixed to the base panel 20 below a predetermined distance before mortar of concrete, and after the curing process is completed, the corner member 70 and the side wall panel 62 are fixed. After releasing, the side wall panel 62 can be easily rotated by lowering the corner member 70.

More preferably, as shown in FIGS. 4 and 5, the angle panel 72 of the side wall panel 62 is formed in a rectangular shape having an upper width smaller than a lower width so as to have a predetermined side angle. Therefore, the side wall panel 62 can be separated more easily.

6 and 7, the fixing bar 73 and the angle panel 72 of the corner member 70 have predetermined angles r and s. As the fixed bars 73 on both sides have parallel angles, or the angle between the fixed bars 73 on both sides increases toward the inside of the formwork device 10, the concrete curing After the process, the corner member 70 may be easily separated from the formwork device 10.
