Description

Mobile Steel Formwork {MOVABLE STEEL FORM}

The present invention relates to a movable steel formwork that can be moved along the ground after the concrete pouring of the roof slab and the wall is completed, and more specifically, by allowing the steel formwork used for concrete pouring to move along the ground in various sections. It relates to a reusable movable steel formwork.

In general, in the case of installing a large apartment complex or public facilities, before constructing a building, the basement is formed to form a pipeline structure so that the pipes for transmission, water supply, and drainage can be installed.

In the construction for forming the pipeline structure, a pipeline structure is formed by forming an inner wall and an outer wall of a steel formwork by a predetermined length and then filling a concrete mixture therein.

After completing the pipeline structure, the outer wall of the formwork should be removed from the pipeline structure and then moved to the next construction section where the pipeline structure is not formed. At this time, since the outer wall of the formwork is formed in a structure in which a plurality of individual formwork is attached in the transverse direction, in order to separate the outer wall of the formwork from the pipeline structure, the assembled formwork is disassembled one by one, and a pipeline structure is used by using separate equipment such as a crane There was a problem in that the work process was very cumbersome and the risk of safety accidents could occur because it had to be moved out of the upper support beam installed in the horizontal direction at the top of the construction section and then installed again in the construction section.

Recently, a rotating steel formwork has been developed to solve the above-mentioned problems.

1 and 2 are sectional views for explaining a conventional steel formwork installed in a box structure. 1 and 2, the conventional rotary steel formwork includes an inner vertical formwork (2) and an upper slab formwork (4), a formwork support (6), an inner vertical formwork (2), and an outer vertical formwork (13). ) A plurality of tie bolts (8) connected to support, the wheel (10) disposed at the bottom of the formwork support (6), the first hinge (11) installed to facilitate the demolding of the inner vertical formwork (2) , A second hinge 12 installed to facilitate demolding of the lower vertical formwork 14. At this time, a rail is installed on the ground, and wheels 10 are placed on the rail on the rail.

In order to separate the steel formwork for the completion of such a pipeline structure, it is necessary to demold the inner molds (2, 4, 14) from the inner wall surface of the structure. For this reason, in the conventional steel formwork, the inner molds (2, 4, 14) were connected in three structural forms.

This structure form the movement of the inner vertical formwork (2) and the upper slab formwork (4) by connecting the ends of the adjacent inner vertical formwork (2) and the upper slab formwork (4) to the first hinge (11). Secured. In addition, the movements of the inner vertical formwork 2 and the lower vertical formwork 14 were also secured by connecting the ends of the inner vertical formwork 2 and the lower vertical formwork 14 with a second hinge 12. This type of structure has the advantage that the inner frame (2,4,14) is connected to the hinge (11,12) is connected, so the inner frame (2,4,14) is less shake during the detachment operation. However, this structure type has a problem in that the inner vertical formwork 2 is damaged from the sidewall of the conduit structure due to the large turning radius of the inner vertical formwork 2 by the first hinge 11. Can occur.

In addition, this structure type has a problem that the movement of the inner mold (2,4,14) is very limited because the inner vertical formwork (2) and the upper slab formwork (4) are not separated and must maintain a minimum length. .

A movable steel material including a wheel portion installed between the second jack supports and a rail portion provided on the ground and providing a movement path to the wheel portion The house offers poodle.

The movable steel formwork according to the present invention can move to a destination even with a small number of people because the external force required for movement is reduced, and noise generated during movement is reduced.

In addition, the present invention can be detached from the box structure where the roof slab formwork and the wall formwork are cured of concrete through a simple operation. Accordingly, the movable steel formwork according to the present invention can be detached from the box structure without damaging the box structure by effectively manipulating the movement of the roof slab formwork and the wall formwork.

In addition, the present invention can shorten the construction period and reduce the construction cost because there is no need to install a plurality of support bars between the outer vertical formwork and the wall formwork.

The first lower formwork 910 is first demolded to provide a function of forming a gap when the first jack support 110 descends and the first wall formwork 300 is demolded, and when the movable steel formwork is moved The wall formwork 300 is provided at the bottom of the first wall formwork 300 so as not to contact the ground to generate friction, and the first hinge at the bottom of the first wall formwork 300 to be rotated in the jack support direction. 920.

The first lower formwork 910 is expanded to maintain the same line as the first wall formwork 300 as shown in FIG. 5 when the movable steel formwork is installed in a desired place for pouring concrete.

The second lower formwork 930 is first demolded to provide a function of forming a gap when the second jack support 120 descends and the second wall formwork 400 is demolded, and when the movable steel formwork moves. The wall formwork 400 is provided at the bottom of the second wall formwork 400 so as not to contact the ground to generate frictional force. The second hinge is provided at the bottom of the second wall formwork 400 so as to be rotated in the jack support direction. 940.

The second lower formwork 930 is expanded to maintain the same line as the second wall formwork 400 as shown in FIG. 5 when the movable steel formwork is installed in a desired place for pouring concrete.

In the following, the demoulding state of the movable steel formwork of the present invention constructed as above will be described based on FIG. 5 when pouring concrete.

As illustrated in FIG. 5, first, the ends of the first and second lower dies 910 and 930 are brought closer to the die support 100 by rotating through the handle 840 of the central pipe 810 of the wall die pulling means 800. Move to detach from the side wall of the box structure.

Subsequently, the height adjustment unit jack 112 of the first jack support 110 and the height adjustment unit jack 112 of the second jack support 120 are operated to lower the roof slab formwork 200 to detach it from the slab of the box structure. At this time, the descending of the roof slab formwork 200 proceeds until the wheel 520 of the wheel part 500 installed on the height adjustment part jack 112 is seated on the rail part 600.

Finally, an external force is applied to the movable steel formwork to move the movable steel formwork along the rail part 600.

Although described above with reference to preferred embodiments of the present invention, those skilled in the art can variously modify and change the present invention without departing from the spirit and scope of the present invention as set forth in the claims below. You will understand that you can.
