Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a method of constructing a concrete structure,

More particularly, the present invention relates to an apparatus and method for maintaining spacing of molds using a small number of parts, as well as facilitating installation and dismounting work, and effectively preventing water from leaking out of the installation space And a method of constructing a concrete structure using the apparatus.

Generally, the most common method of forming various pillars, walls, and the like in construction of civil engineering structures and the like is a method of curing after injecting the concrete into a frame that is constantly woven so as to have a predetermined shape, It takes about two days to remove the mold when it forms a retaining wall.

In this way, the formwork, which is designed to place concrete between a pair of inner and outer panels, must maintain a constant gap between the inner and outer panels until the completion of curing so as not to deviate from the designed dimensions. It is a form spacing maintenance device.

Accordingly, the mold space maintaining device basically has a function of preventing the panels from spreading beyond a predetermined interval when the concrete is laid on the inner and outer sides, that is, fixed on the inner and outer sides, that is, the gantry and the euro foam. .

A conventional apparatus for spacing a concrete pouring formwork related to such a technique is disclosed in Korean Utility Model Registration No. 326109, and its construction is fixed through a first formwork (for example, a gantry) and a second formwork Shaped member having a circular cross-section so as not to spread out beyond a predetermined distance between the first and second molds when pouring, so as to appropriately secure the concrete pouring space between the first and second molds according to the design And has a sufficient length, and at one end, a securing tie is formed through which a securing slot for inserting a fixture is inserted.

A threaded portion is formed at one end of the separator, and a cut groove is formed in the vicinity of the other end where the fixing slot is formed, so that it can be cut after the concrete is poured.

Further, a bolt having a screw thread, a washer, a bracket, a spring, and a hexagon head connut are inserted and inserted into a vertical plate in an integrated assembly form.

However, the above-mentioned die spacing maintenance apparatus is constituted by bolts, connuts, septa, and fasteners, and manufacturing cost is high due to the manufacture of each single item, and each single item must be stored in a disassembled state or stored in combination, .

In addition, since the adjustment of the length of the bolt and the septa for holding the gap is usually performed only on the side of the bolt, the length adjustment operation is very inconvenient, and there is a disadvantage in that the twisting and separation occur between the materials.

In order to solve such a problem, there is an apparatus for maintaining spacing of a concrete form using an integral body bolt registered by the present applicant as a utility model (Patent Document 1, Registration No. 20-0437568).

As shown in FIG. 1, Patent Document 1 discloses a space holding device for holding a space between first and second dies formed by joining a plurality of long joists and a yoke on an outer surface, Which is screwed to both sides of the screw rod 1 and is supported on the yoke of the first and second molds 2 and 3 through the nuts 6 and 7, And a washer interposed between the first and second main body bolts and the first and second main bodies. The first and second main body bolts (4, 5) The straight portions 4b and 5b extending in the rear of the cone nut portions 4a and 5a and the straight portions 4b and 5b are formed in the middle of the conical nut portions 4a and 5a, (4b, 5b), a second support portion which is formed so as to have a larger diameter than the straight portions (4b, 5b) at the ends of the straight portions (4b, 5b) On And a wrench portion which is rotated by the tool and rotates the cone nut portions (4a, 5a) to adjust the length of the gap maintaining device, the washer being opened toward the lower portion, and the first and second body bolts And a head portion formed at an upper end of the vertical plate.

Patent Document 2 (Japanese Patent Application No. 10-1320699) discloses a screw threading machine having a threaded rod formed on an outer circumferential surface thereof, a threaded rod fixed to both sides of the threaded rod, supported by a stiffener provided outside the first and second formworks, First and second body bolts, first and second support plates for supporting the first and second body bolts on a stiffener provided on the outside of the first and second molds, And a first and a second fastening nuts for supporting the first and second body bolts to the first and second workpieces through a support plate, wherein the first and second body bolts include first and second body bolts A first and a second connuts respectively formed at opposite ends of the first and second body parts and screwed to the screw threads, and a second cone part having a larger cross-sectional area than the first and second body parts, A first and a second support portions formed in an outer peripheral portion of the first and second body portions, Wherein the first and second support plates include first and second support plate bodies supported by a reinforcing member provided outside the first and second molds, Wherein the first and second screw portions of the first and second main body bolts are formed in the central portion of the main body and the first and second wedge grooves of the tapered section are supported by the first and second support portions in a wedge- The first and second bolts are fastened to the first and second support plates in a wedge-like manner by fastening the first and second fastening nuts, thereby maintaining the gap between the first and second dies.

Since both the screw rods and the two body bolts and the nuts are essential components, the installation and disassembly operations are very cumbersome and complicated, and the bolts of the body are inserted into the molds through the inserted plates (plywood etc.) That is, since the fastening position of the body bolt and the screw rod is a narrow space inside the formwork, it is very difficult to install and the air becomes long.

Also, since the body bolt is embedded in the concrete, there is a problem that the body bolt is not easy to disassemble.

In addition, the mold has a fastening hole for receiving the body bolt. Since the cone nut portion of the body bolt has a large size, a part where moisture can leak becomes large, and it is very difficult to secure the water tightness.

≪ Example 1 >

As shown in FIGS. 2 and 3, the mold space maintaining apparatus according to the present embodiment is installed between the first and second molds 2 and 3, 3 which are joined to the circumferential portion of the spacing rod 10 and are in close contact with the fastening holes 2a and 3a of the first and second formwork 2 and 3 to be waterproof, 20, and fastening bolt rods 30 as fastening means fastened to both sides in the longitudinal direction of the gap retaining rods 10, respectively.

The gap holding rods 10 are formed on both sides of the rod body 11 in the longitudinal direction of the rod body 11 and are provided with a threaded portion 12 as a coupling portion to which the fastening bolt rod 30 is detachably fastened, (13) formed adjacent to the screw portion (12) at both sides in the longitudinal direction of the threaded portion (11) and spaced apart from each other by a certain distance inwardly, and fractured by an external force.

For example, the rod body 11 may have a circular cross section as a whole and may have a circular cross section on both sides in the longitudinal direction for the formation of the thread portion 12 and a cross section other than a circular cross section. Further, the rod body 11 is not limited to a circular shape but may be square (triangular or rectangular) or more.

The threaded portion 12 is machined on the outer circumferential surface of the portion protruding from the first and second molds 2 and 3 at the rod body 11 to fasten the fastening bolt rod 30, Since the assembly of the rods 30 is performed in a wide area outside the first and second formworks 2 and 3, the installation of the first and second formworks 2 and 3 and the maintenance work of the gap are very easy.

The threaded portion 12 is fastened to the fastening bolt 30 to be supported by the first and second formwork 2 and 3, and thus includes threads other than threads.
