INSERT SECURING PIECE USED IN THE CONSTRUCTION OF NUCLEAR POWER STATIONS

Abstract

 The insert securing piece used in the construction of nuclear power stations of the present invention comprises: a close fitting part which has the shape of a plate curved at both ends, has the same length as the width of the insert and is formed so as to be parallel with the insert in such a way as to closely fit the upper part of the insert; curved parts at both ends of the close fitting part, which have a length that is the same as the thickness of the insert and are formed so as to curve in such a way as to cover both the left and the right end of the insert; and securing parts at both ends of the curved parts, which securing parts have a length and are formed so as to be parallel with the close fitting part in such a way as to firmly secure the insert to a frame; and the close fitting part is also formed with a protrusion formed so as to protrude along the length in such a way that the close fitting part firmly establishes close fit against the upper part of the insert while the close fitting part is prevented from bending or deforming and becoming damaged during securing by means of the securing part.

Description

Cross-reference to related application

[0001] This application claims the benefit of Korean Patent Application No.20-2010-0008552, filed on August 17, 2010 in the Korean Intellectual Property Office, the disclosure of which is incorporated herein by reference.

Technical Field

[0002] The present invention relates to an insert securing piece used for construction of a nuclear power station, and more particularly, to an insert securing piece for securing an insert inserted into a mold when constructing a nuclear power station, integrally formed with a building after the mold is removed, and for installing a structure.

Background Art

[0003] In general, at a construction site, in order to bury an insert into concrete, through a process of firmly securing the insert to the inside of a concrete pouring mold, pouring and curing concrete to the insert, and separating an insert securing piece together with the mold, the insert is buried into the concrete.

[0004] However, when constructing a nuclear power station, in view of a characteristic of the nuclear power station, structures having a heavy weight are integrally formed with a building.

[0005] Therefore, an insert securing piece used in a general construction site does not firmly secure an insert used for construction of a nuclear power station to a mold and thus there are problems that insert securing pieces much more than those used in a general construction site are installed or a separate reinforcing work is necessary.

Technical Problem

[0006] The present invention is made to overcome the above mentioned problems, and it is an object of the present invention to provide an insert securing piece in which a close fitting part is bent or deformed to be prevented from being damaged and firmly close contacts with an upper portion of the insert, and the insert securing piece used for construction of a nuclear power station, when securing an insert of a heavy weight used only upon constructing the nuclear power station to a mold, as the insert securing piece includes the close fitting part having a convex portion.

[0007] It is another object of the present invention to provide an insert securing piece used for construction of a nuclear power station that minimizes a clearance of an insert by enclosing both ends of the insert with curved parts.

Technical Solution

[0008] To achieve the above objects, there is provided an insert securing piece used when constructing a nuclear power station and having a plate shape in which both ends are bent, the insert securing piece including: a close fitting part having the same length as a width of the insert and formed parallel to the insert to close contact with an upper portion of the insert; curved parts bent with the same length as a thickness of the insert at both ends of the close fitting part to enclose both ends of the left and the right of the insert; and securing parts having a length at both ends of the curved parts and formed parallel to the close fitting part to firmly secure the insert to the mold, wherein the close fitting part includes a convex portion convexly formed in a length direction to prevent the close fitting part from being damaged by bending or deformation when securing with the securing parts and firmly close contacts with an upper portion of the insert.

[0009] Further, the securing parts include a plurality of securing holes penetrated with separated by a gap from each other and securing pins inserted into the securing holes to be secured to the mold.

Advantageous effects

[0010] According to the present invention, as an insert securing piece includes a close fitting part having a convex portion, when securing an insert of a heavy weight used only upon constructing a nuclear power station to a mold, the close fitting part is bent or deformed to be prevented from being damaged and firmly close contacts with an upper portion of the insert.

[0011] Further, by enclosing both ends of the insert with curved parts, a clearance of the insert is minimized.

Best modes for carrying out the invention

[0020] Hereinafter, an exemplary embodiment of the present invention will be described in detail with reference to the accompanying drawings.

[0021] FIG. 1 is a perspective view illustrating an insert securing piece used for construction of a nuclear power station according to the present invention, FIG. 2 is a cross-sectional view illustrating the insert securing piece used for construction of the nuclear power station of the present invention taken along line A-A of FIG. 1, and FIG. 3 is a perspective view illustrating a use state of an insert securing piece used for construction of a nuclear power station of the present invention.

[0022] As shown in the drawings, an insert securing piece 10 having a plate shape in which both ends are bent and used for constructing a nuclear power station according to the present invention firmly secures an insert 5 inserted into a mold 1 when constructing a nuclear power station and integrally formed with a building after the mold 1 is removed to install a structure, and includes a close fitting part 11, curved parts 13, securing parts 15, and a convex portion 17.

[0023] The close fitting part 11 has a plate shape, has the same length as a width of the insert, and is formed parallel to the insert 5 to close contact with an upper portion of the insert 5.

[0024] In this case, the close fitting part 11 changes a length according to a width of the insert 5.

[0025] The curved parts 13 is bent with the same length as a thickness of the insert 5 at both ends of the close fitting part 11 to enclose both ends of the left and the right of the insert 5.

[0026] In this case, the curved parts 13 change a length according to a thickness of the insert 5.

[0027] The securing parts 15 have a length at both ends of the curved parts 13 and is formed parallel to the close fitting part 11 to firmly secure the insert 5 to the mold.

[0028] The securing parts 15 include a plurality of securing holes 15a penetrated with separated by a gap from each other and securing pins 15b inserted into the securing holes 15a to be secured to the mold 1.

[0029] In this case, the securing holes 15a and the securing pins 15b of the securing parts 15 are secured to the mold 1, are poured with concrete together with the insert 5, and are buried, unlike a general construction site.

[0030] In such a structure, the close fitting part 11 has a convex portion 17 convexly formed in a length direction.

[0031] When the close fitting part 11 is secured to the mold 1 using the securing parts 15, the close fitting part 11is bent or deformed to be prevented from being damaged, and the convex portion 17 enables the close fitting part 11 to firmly close contact with an upper portion of the insert 5.

[0032] In this way, according to the present invention, as a close fitting part having a convex portion is provided, when securing an insert of a heavy weight used only when constructing a nuclear power station to a mold, the close fitting part is bent or deformed to be prevented from being damaged and firmly close contacts with an upper portion of the insert.

Industrial Applicability
