[0001] DESCRIPTION [0002] LINEAR CONTROL AND FIXING DIVICE OF GIRDER [0003]

The present invention relates to a linear adjustment and fixing device for a girder, and more particularly, to a design and construction method of a key segment in order to serialize a girder in a bridge constructed by FCM (Free Cantilever Method) To a linear adjustment and fixing device for a girder which is capable of linear adjustment and fixing such that the linearity of the girder is matched.

Generally, a bridge is a structure that traverses a river or the like, and is composed of a bridge pier foundation, a pier bridge, and a girder installed on the pier bridge head, and there are a bridge, a railway bridge, a bridge bridge and the like.

These bridges consist of a number of bridge piers that are spaced at regular intervals from each other, and girders that are sequentially constructed from any bridge pier according to the alternation and construction procedure.

The FCM (Free Cantilever Method) method uses special equipment to make the girders constructed at each bridge pier in order to be balanced with each other in left, right, and bottom and form a span, This is the method to complete the upper girder.

In this case, it is common that the girders are linearly matched at a position connecting the girders by a single girder. However, there is a problem that the linearity of the connection portions is not coincident due to a construction error or the like.

Therefore, in order to solve the above-mentioned problem, conventionally, in order to solve the above-mentioned problem, about four concrete blocks are manufactured at the construction site, then two concrete blocks are installed on the upper surface of one of the girders, And then fix it on the upper surface of the girder with vertical steel rods. Two tensile materials were horizontally inserted into the concrete block in the X - shape horizontally on the large crack block, and then tensioned at the tensile fixture to adjust the two girders facing each other to have a linear shape.

However, in the case of the conventional concrete block, when the tensile fixation of the X-shaped tensile material due to the manufacturing error in the real production, the installation error of the block facing the diagonal line, and the deviation angle occurring in the correction process of the girder, There is a problem in that the bent tensile material is broken and the reuse is impossible and the concrete process is complicated and the concrete waste is discharged after the use such as the inconvenience of the excessive use of the weight

In addition, the upper brace is installed in the girder wall, and it is very difficult to install due to the interference with the existing reinforced bar during the installation, and the high strength mortar should be filled so that the end of the brace receives the uniform distribution load with the segments. In addition, when concrete is poured, even if pores are formed at the bottom of the braces, measures can not be taken and they are buried in concrete spheres and can not be reused.

The bottom brace is also located between the inner and outer weights of the girder so that both ends of the lower brace are filled with high strength mortar so that both ends receive uniformly distributed load. Curing time is required until the design strength is reached, Dismantle after cutting. Therefore, there is a problem that an expensive product is produced and used after one-time commercial use

Hereinafter, for convenience of description, the girder positioned on the right side of FIG. 1 is referred to as a first girder G1, and the girder positioned on the right side thereof is referred to as a second girder G2.

The saddle portion 10 serves as a base on which the linear regulating portion 20 and the control portion 30 for aligning the linearity of the first girder G1 and the second girder G2 are provided. G1 and the second girder G2.

At this time, the saddle portions 10 fixed to the upper surfaces of the first girder G1 and the second girder G2 are spaced apart from each other and positioned on the same line.

The saddle portion 10 includes a plurality of ribs 12 crosswise formed in the longitudinal direction and the transverse direction within a housing 11 of a rectangular box shape whose upper surface is opened.

A plurality of divided spaces are formed in the saddle portion 10 due to the ribs 12. The operator can move the saddle portion 10 through the partitioned space without depending on the position of the tandem to be installed later, The saddle portion 10 can be easily fixed to the upper surface of the first girder G1 and the second girder G2 through the fixing member 50. [

In addition, since the rib 12 increases the rigidity of the saddle portion 10, the saddle portion 10 is not warped or deformed in the course of aligning the linearity of the first girder G1 and the second girder G2 .

The fixing member 40 is in the form of a circular bar having a predetermined length and diameter, and a spiral is formed on the outer circumference.

On the surfaces of the saddle portions 10 facing each other, the hinge pieces 13 spaced in the upward and downward directions are formed.

Since the hinge piece 13 is formed in a spaced-apart form, a receiving space for receiving a part of the control unit 30, which will be described later, is formed therebetween.

The combination of the saddle portion 10 and the control portion 30 via the hinge piece 13 will be described in detail below.

The saddle portion 10 described above is provided with a pair of upper struts 60 for preventing sagging of the first girder G1 and the second girder G2.

The upper brace 60 includes an upper brace member 61, a first bracket 62, a fixing unit 63, and a connection unit 64.

As shown in FIG. 1, the upper strut member 61 is provided between the saddle portion 10 fixed to the first girder G1 and the saddle portion 10 fixed to the second girder G2. As shown in Fig.

At this time, the upper strut member 61 is formed of a material having superior rigidity so as to stably support the load of the first girder G1 and the second girder G2 to prevent sagging, and has a constant length and thickness Shaped bar or polygonal bar shape.

The first fastening portions 611 are protruded from the central portions of both side surfaces of the upper strut member 61.

The first fastening part 611 is for integrally fastening the upper supporting part 61 to the fixing part 63 and is formed in the form of a bolt having a predetermined length and diameter and formed with a spiral on the outer peripheral edge.

Therefore, the entire outer surface of each of the hatches and the upper braces is not flat, and an inclined or curved portion is formed intermittently.

When the both ends of the conventional upper brace are brought into contact with the hammers, there is a problem that an empty space is generated between them. To solve this problem, the non-shrinkage mortar must be cured in the empty space. There is an increasing problem.

However, since the second receiving portion 632 and the first receiving groove 62a applied to the linear adjusting and fixing device 1 for a girder according to the present invention are formed to have a size and a curve corresponding to each other, The portion 632 is formed in such a manner that when the first receiving groove 62a is received in the first receiving groove 62a, a portion of the first receiving groove 62a is completely separated from the inner surface of the first receiving groove 62a. In addition, since the inner wall surface of the first receiving groove 62a serves as a supporting jaw for supporting the second receiving portion 632, the second receiving portion 632 is completely prevented from being drawn out, The upper brace 60 can be securely coupled to the saddle portion 10 in a completely close contact state without being poured and cured.

At this time, the first girder G1 and the second girder G2 can be formed in the form of a segment, and a plurality of first girders G1 are successively installed from one pier to another opposite pier, The second girders G2 can be sequentially installed from the other piers toward the bridge piers at which the first girder G1 is constructed.

Here, the construction method of the piers and girders is generally the same as that used in the construction of bridges or railways, and therefore, a detailed description thereof will be omitted.

Subsequently, as shown in FIG. 8, the second girder G2 may not be perfectly horizontal with respect to the first girder G1, and may be installed in a tilted form in one direction.

In this case, the angle of the second girder G2 is adjusted through the tension fixing unit 31 fixed to the saddle portion 10a fixed to the upper surface of the first girder G1, It is possible to achieve a perfect linearity.

Concretely, the hose of the hydraulic pressure supply part 314 is connected to the hole 311c of the first housing 311 fixed to the saddle part 10a, and the hose of the hydraulic pressure supply part 314 is connected to the access hole 3131a of the main body 3131, The rod 3132 is moved in a direction to be drawn out from the inside of the main body 3131 to tension the linear regulating portion 20. [

When a tensile force is generated in the linear regulating portion 20 located on the saddle portion 10a as described above, the saddle portion 10b positioned on the diagonal line and the saddle portion 10b of the entire portion of the second girder G2, The portion to which the fixing portion 10b is fixed is pulled together.

Therefore, the operator adjusts the amount of hydraulic pressure supplied to the main body 3131 through the hydraulic pressure supply unit 314 to adjust the tensile force applied to the linear regulator 20 so that the first girder G1 and the second girder G2 ) Can be made perfectly linear.

When the linear regulator 20 is tensioned, the first tension guide 312 is also moved to be spaced apart from the end surface of the first space 311a, so that the operator can rotate the first tension guide 312 So that the linear regulating portion 20 is not pulled back toward the saddle portion 10b by being received and supported in the fixing groove 311d.

Although not shown in the figure, when the second girder G2 is opposite to the first girder G1 in the form of being opposite to the first girder G1, the first girder G1 is fixed to the saddle portion 10c A tensile force is generated in the linear regulating portion 20 through the tension fixing portion 31 so that the saddle portion 10d located on the diagonal line and the saddle portion 10d of the whole portion of the second girder G2 are fixed So that the first girder G1 and the second girder G2 can be linearly formed.

Further, since the linear adjustment and fixing device 1 for a girder according to the present invention has a structure in which the control portion 30 is rotatably coupled to the saddle portion 10, the linearity between the girders G1 and G2 is excessively shifted, The saddle portion 10 is separated from the girders G1 and G2 and then the saddle portion 10 is changed to change the position or angle of the linear adjustment portion 20 The position and angle of the linear regulating portion 20 can be easily adjusted by only rotating the tension fixing portion 31 and the fixed fixing portion 32 while the saddle portion 10 is fixed in place It is possible to remarkably shorten the working time for adjusting the linearity of the girder and to provide an effect that the work can be carried out very conveniently.

The present invention has been described above with reference to the embodiments shown in the drawings. However, the present invention is not limited thereto, and various modifications or other embodiments falling within the scope of the present invention are possible by those skilled in the art.
