The present invention relates to a formwork for installing milestones or signs, and more particularly, to a prefabricated formwork made of concrete.

In general, the formwork is a hypothesis that maintains a predetermined shape and dimensions during the curing of the concrete, to prevent the leakage of moisture until the concrete is hardened and to protect it from the influence of the outside air, and is a construction that is dismantled after the concrete is cured.

As such formwork, concrete formwork plywood is used. Depending on the construction, hard fiber board, synthetic resin, aluminum panel, steel sheet, etc. may be used.

The formwork requirements should not have sufficient strength and deformation to withstand various external forces (concrete load and dynamic load) and ensure precision and water solubility that shape and dimensions can be maintained accurately. In addition, the material cost is low, it is economical due to repeated use, it is easy to process, assemble and dismantle, and it is light to be easy to transport, handle and load, and the material should be easy to clean and repair.

Types of formwork by material include wood formwork, plywood formwork, metal panels such as steel panels and aluminum panels, and aluminum formwork. Forms of formwork include general formwork, euro form, sliding foam, vertical formwork, There are table formwork, tunnel formwork, waffle formwork and traveling formwork.

In assembling the formwork such as the Euroform, a large number of manpower and materials are required, the construction process of the formwork is complicated and takes a long period of construction, the gap between the assembly parts, when the concrete is leaked or poured concrete Formwork has often been destroyed by pressure.

Figure 1 shows the installation structure of a general milestone.

Referring to the drawings, the support pillar 10 of the milestone 20 is a trench in the sidewalk 60 is installed on the edge of the road 70, form the form to fit the concrete lower layer 40 after pouring concrete After curing and hardening, after curing by forming the upper concrete layer 50 in the same manner, after removing the formwork, it is installed in a manner to fill the soil back to the dug, a milestone fixed to the upper concrete layer 50 The support column 10 is reinforced through the reinforcing means 30 such as a bolt to be stably supported.

That is, in general, a method for installing a milestone or a sign is a trench for embedding a lower portion of the support pillar 10, forming a form into the pit by the trench, and placing concrete inside the formwork. Step, curing the pour concrete, step of removing the formwork attached to the outside of the cured concrete, backfilling step of refilling soil in the outer space of the formwork and finishing reinforcement step.

However, the existing construction method requires a work space necessary for the worker to assemble the formwork, so that the excavation area must be relatively large, so that the ground is weakened even by refilling it, and when installing milestones, etc. It can not be attached to the edge of the road. Therefore, there is a problem that the milestones are installed away from the road and eventually weaken visibility by increasing the angle of incidence.

 In addition, the frame of the conventional Eurofoam type formwork extends a ridge protruding from the edge of the frame to form a fastening groove to which the flat tie bar can be fastened, thereby forming a recess along the entire edge of the frame. . When the formwork is arranged in series and fastened, the recesses of the frame of one formwork and the recesses of the frame of another formwork are in contact with each other to form a rectangular space when viewed from the cross section. Uncured concrete penetrates into the space and hardens. In addition, the unhardened concrete penetrates and hardens into the space formed by the recessed portion through the gap between two adjacent fastening grooves. Particularly, in the case of forming the bottom surface of the building structure, more uncured concrete penetrates into the recess through gaps formed by two fastening grooves adjacent to each other, and thus, more concrete is hardened and fixed there.

In addition, as an example of a conventional euroform type formwork, it has been disclosed as a Euroform type formwork having a reinforcing structure in Korean Patent Publication No. 2004-13614.

The disclosed Euroform formwork is composed of a frame that forms a quadrangular overall and an angle for partitioning and supporting the inside of the frame at appropriate intervals, and is coupled to the front of the frame part supporting the plate to directly receive a load of unhardened concrete. Made of ash board.

However, the above-described invention also discloses a flow-form-type formwork capable of preventing bending and breakage of the plate, but is not a structure capable of solving the above problem.

Therefore, there is a need for concrete formwork and its installation method for fixed installation of a milestone or signage in a new way that can solve the above problems.
