Description

[0001] Height-adjustable Steel Mold [0001]

The present invention relates to a steel formwork, and more particularly, to a steel formwork capable of adjusting the height of the steel formwork by varying the height of the steel formwork according to a construction situation when the concrete runway is installed.

Automotive Guideway Transit (AGT) is a light rail that uses rubber tires as the wheels of a railway vehicle. Since the rubber wheel AGT affects ride quality depending on the condition of the concrete runway that rubber tires contact with, it requires precise construction for concrete pouring. As a method of constructing such a rubber wheel AGT, a formwork is installed on both sides of a pier and a foundation concrete on both sides of a running road, and concrete is installed and cured therein to construct a running road. At this time, the pier and foundation concrete have locally small difference in height depending on the flatness, so that the height of the road is adjusted to keep the road surface constant. In this way, in order to adjust the height of the runway to keep the runway surface constant, the height of the formwork must be adjusted corresponding to the height of the runway. Therefore, in order to control the height of the form by a conventional mold composed of a single plate, it is necessary to provide various plates depending on the height, which makes it difficult to adjust the operation and level of the plate.

In addition, since various shapes of the plates must be provided depending on the height, the kinds and quantity of the molds are increased, and the costs of material management and storage are increased. In addition, since the different mold plates must be connected according to the height of the traveling passage, the construction time due to the connection and adjustment of the mold is delayed during the mold installation, thereby decreasing the workability and work efficiency. In addition, concrete pouring is not precise, so concrete concrete surface treatment such as grinding and grinding after running concrete should be performed. As a result, the work schedule is increased and the quality of the running road may be deteriorated by the surface treatment .

On the other hand, Japanese Patent Application Laid-Open No. 10-0828078 (Patent Document 1) discloses a floor member having a flat or curved plate shape and contacting the floor; A height regulating member which is formed in a bar shape and has a plurality of vertical portions at regular intervals on the outer surface of the bottom member, the upper end of which extends to the upper side of the bottom member; The outer surface of the bottom member has an outer surface corresponding to the inner surface of the bottom member so that the outer surface of the bottom member touches the outer surface of the bottom member and the outer surface of the bottom member has an outwardly protruding portion, And a movable member having a guide hole formed therein and sliding up and down along the inner surface of the bottom member, the height of which is controlled by moving the movable member up and down according to the designed height, And Patent Document No. 10-0908266 (Patent Document 2) does not require a cantilever bracket for installing a formwork, which facilitates height adjustment when a slab camber form on the road surface of a bridge is installed It is easy to disassemble, and the structure of the multi beam for assembling the form is simplified, minimizing the number of parts required, The beam was adjusted to the desired height when adjusting the height of the inner beam, which is fastened after the operator without fixing process easily adjusted via the handle to the desired height "height for the handle is provided with die control device" is disclosed.

However, in the above-described Patent Documents 1 and 2, it is possible to adjust the height of the form by moving the sliding member moving up and down, or to easily adjust a desired height by using the handle, but the height adjusting mechanism is generally complicated, There is a problem that the operator is not easy to handle. It is also possible to adjust the height but not at the same time to perform a leveling operation on the concrete surface.

The state after the overall height of the form is adjusted (in the case of (B), the height is adjusted to the maximum). At this time, the height from the foundation concrete surface to the upper end of the vertical steel plate member 121 of the height control form 120 is 350 mm. Therefore, when the running road concrete pouring work is performed using the height control formwork 120 of the present invention, the height can be freely adjusted within a range of 0 to 130 mm. Accordingly, it is possible to fundamentally solve the problem of providing various shapes of the plate bodies according to the height in order to adjust the height of the form as in the conventional art.

In the state where the formwork 100 is installed as described above, a ready-mixer is installed in a space formed by the formwork 100 installed on both the foundation concrete floor (base floor) and the foundation concrete floor, thereby constructing the traveling road.

In the above-described series of processes, when the ready mixer is installed, the formwork 100 is subjected to side pressure of the ready mixer, so that a considerable stress is applied to the back face of the formwork (the face opposite to the face contacting the ready- However, the first and second reinforcing members 114a, 114b are provided on the mold 100 (more precisely, the stationary mold 110) of the present invention, so as to resist the stress caused by the side pressure of the ready- It is possible to prevent deformation of the back surface of the mold due to the deformation.

5 is a view illustrating a process of selecting a surface in a process of constructing a concrete runway using a height-adjustable iron formwork according to the present invention.

Referring to FIG. 5, as described above with reference to FIG. 4, the height-adjustable iron formwork 100 according to the present invention is installed on the side of a traveling road along the longitudinal direction of the concrete running road, (100) is installed, concrete is installed in a space formed by the formwork (100) provided on both the foundation concrete surface (bottom surface) and the foundation concrete surface to construct the traveling road.

In the course of the above-described series of steps, the concrete setting apparatus 500 is placed on the rail 123 for the face leveling apparatus and moved horizontally so that the surface of the poured concrete is leveled. Therefore, there is no need to perform separate grinding and polishing operations after concrete pouring work. As a result, it is possible to prevent the deterioration of the traveling path due to the work schedule delay and the surface treatment as in the prior art.

On the other hand, the face leveling device 500 has a V-shaped concave groove formed in the wheel 501 to engage with a right angle portion of the "a " -shaped angle of the rail 123 for the face leveling device, 123 so that they can be easily horizontally moved along the rails 123 for the face leveling device.

As described above, the height-adjustable iron formwork according to the present invention is composed of a fixed formwork fixed to a foundation concrete surface and a height-adjustable formwork capable of being engaged with and separated from a fixed formwork. In the height-adjustable formwork, Since the rail is installed and the height of the form can be variably controlled by the height control form according to the situation of the construction site when the concrete runway is installed, the surface of the concrete runway can be kept constant, Precise construction is possible. In addition, it is not necessary to provide a variety of plate molds according to the height of the base surface as in the prior art, and it is possible to prevent the cost increase due to the material management and storage due to the increase in the kinds and quantity of the molds.

In addition, since the surface roughing device can be operated in the field by using the rails for the surface roughing device, it is possible to immediately perform the surface roughing operation together with the concrete pouring, thereby minimizing the polishing and grinding work. As a result, it is possible to prevent the deterioration of the traveling path due to the work schedule delay and the surface treatment as in the prior art.
