HIB beam structure with connecting part reinforcing device for making long span mold beam

The present invention relates to an H-beam structure having a connection reinforcing device for manufacturing a long-span mold, and more particularly, to a H-beam reinforcing device for manufacturing a long-span mold, Lt; RTI ID = 0.0 > beam < / RTI >

Generally, in the case of a subway construction, it is usually difficult to exceed the interval of the intermediate file by 7.0m when the interval of the intermediate file is adjusted to the traffic processing plan. Therefore, the stress of the mold beam, which can be spaced at least 10m inevitably, The installation interval of the intermediate file is narrowed due to the inability to utilize it, and the construction space becomes narrow.

In order to solve the above-described problem, a fixing base 14 is formed on the lower part of the mold support 12, and a gap between the mold plate 28 and the steel plate 30 and the high- (32), the interval between the intermediate files can be increased, and the amount of use of the intermediate files can be reduced. However, in order to avoid interference between the bolt head and the flat plate 34 when the high tension bolt 32 is connected, there is a disadvantage in that the flat plate 34 having the recessed portion 36 is separately required.

Also, considering the uncertainty of securing precise quality control and the influence of vibration load transferred from the laminating board and the horseshoe, the jointing work of the mold beam (H. beam) is a very poor working condition for the field workers. Unlike the result of numerical analysis, the reliability of the connection part may decrease the reliability of maintaining the safety. Therefore, we propose a new technique reinforcement method as reinforcement method due to uncertainty of construction quality and influence of vibration load.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings. However, the scope of the present invention should be understood from the description of the claims. Further, the description of known technology which obscures the gist of the present invention is omitted.

The present invention is summarized as follows.

That is, in an H beam structure in which two or more H Beams 100 are interconnected,

The H Beam (100)

An end portion of the H. beam 100 and a reinforcing angle 140 below the upper flange 110,

The reinforcing angle (140)

An H-beam joining portion 141 in which two longitudinally parallel corners of the H-beam 100 are bonded to the upper flange 110 and the web 120, respectively,

A reinforcing angle inner space 144 formed by joining the reinforcing angle 140 with the upper flange 110 and the web 120,

A reinforcing angle joint 142 is formed at the joint where each reinforcing angle 140 abuts when the two H-beams 100 are connected

Wherein the at least two HIBs 100 are formed so as to be aligned with each other in the longitudinal direction so that the reinforcing angles 140 of the respective HIB beam ends are adjacently joined to each other

To an H-beam structure having a connecting portion reinforcing device for manufacturing a long span mold beam.

FIG. 4 is a schematic view showing the construction of a conventional retaining structure in which an intermediate file is installed, FIG. 5 is a perspective view of an improved retaining structure in which an intermediate file is excluded, Effect can be confirmed. The intermediate file 200 is for supporting a lower mold beam (H. beam) connection which forms a temporary driveway. That is, when a general HI beam 101 having no reinforcing angle 140 is used as a mold beam, stress is exerted on the connection between the two mold halves 101a and 101b due to vibrations and loads caused by passenger vehicles The intermediate file 200 needs to be installed since it can not be maintained with a general coupling construction.

However, if the connection between the two mold halves 100a and 100b is reinforced as shown in FIG. 5, it is possible to support only the temporary base 300 without installing the intermediate file 200. Therefore, the interval between the intermediate files can be increased, It is possible to reduce the net construction cost naturally and it is advantageous to use the working space of the temporary sectional plane more efficiently because of the reduction of the intermediate file.

The above effect is disclosed in Patent No. 10-1058784.

FIG. 3 is a detailed view (a) of a mold connection method of the present invention taking into consideration the traffic process according to the registration number 10-1058784, a side detail view (b) showing a state in which a flat plate is installed on a mold beam, It is connection method (c) for use.

The method of connecting the mold to the temporary mold considering the traffic treatment according to the patented invention includes the steps of installing the mold support (I), forming the hypothetical foundation (II), installing the mold (III); The method of excluding the intermediate file is proposed by sequentially performing the step of connecting the mold beam (IV) and the step of installing the block board (V).

That is, as shown in FIG. 3 (a), a temporary foundation 14 is formed on the lower part of the mold support 12, and the intermediate part of the mold beam 28 is connected to the steel plate 30 and the high tension bolt 32, The interval between the files can be increased, and the usage of the intermediate file can be reduced.

However, as shown in FIG. 3 (b), there is a disadvantage in that a separate plate 34 is required in order to avoid interference between the bolt head and the flat plate 34 when the high tension bolt 32 is connected.

Since the base plate is a temporary product and is intended for temporary use for a short period of time, a conventional large-sized base plate is used. Therefore, additional production of the base plate with the groove 36 results in a time-consuming and economical loss. In addition, there is a problem that it is difficult to reuse the base plate on which the recessed trench 36 is formed, other than the above-mentioned applications.

However, as shown in FIG. 3 (c), when the upper region is welded only, the stress is lowered. Therefore, various measures such as safety, ease of installation and quality are required.

FIG. 1 is a perspective view of an H-beam connector according to an embodiment of the present invention, FIG. 2 is a sectional view of FIG. 1, and FIG. 9 (a) is a perspective view of a H Beam 100 provided with a reinforcing angle 140. In Fig. 9 (b), a connection example of the HR beam can be confirmed.

1 and 2, according to the present invention, the reinforcement angle 140 is further formed in the H Beam composed of the upper flange 110, the lower flange 130 and the web 120 to reinforce the stress of the mold connecting portion Suggest ways to do it.

The HIB beam 100 having the reinforcing angle 140 formed thereon is brought into contact with each other in the longitudinal direction so that the reinforcing angle 140 of each H-beam beam end portion is parallel to the longitudinal direction of the H- They are combined in the neighborhood.

The reinforcing angle 140 is formed at the end of the HI beam 100 and below the upper flange 110. A design change such as being formed on one end or both ends of the HUB 100 in accordance with the required specifications, on the end face or both sides of the web 120, or from one end to the other end of the HUB 100 This is possible.

In this embodiment, as shown in FIG. 9, when four sides of the web 120 and both sides of the HR beam 100, i.e., the HR beam 100, are viewed from the top, four reinforcing angles 140 are provided As a reference.

FIG. 10 is a view showing the structure of the reinforcing angle in an exploded view of the HR beam. FIG.

The reinforcing angle 140 is formed by the H-beam joining portion 141 and the reinforcing angle joining portion 142.

The H Beam joining portion 141 is a portion where two corners of the longitudinally parallel reinforcing angle 140 of the H Beam 100 are joined to the upper flange 110 and the web 120, It is difficult to secure quality due to uncertain conditions in welding, so it is desirable to construct the plant by factory welding (shop welding) (s1 step).

The welding length calculation formula for securing the safety during construction by fillet welding is as follows. The reference dimension (unit: mm) of this embodiment is H-beam width 300 x height 900, L-shaped steel width 120 x height 120 x thickness 8. In this case, the welding length is designed within the range of 440 to 500 mm.

The reinforcing angle 140 is joined to the upper flange 110 to share the impact due to the up-and-down vibration and is bonded to the web 120 to disperse the impact into the web 120, ) In the direction of the arrow. Accordingly, as shown in the cross-sectional view of FIG. 2, the reinforcing angle 140 is an angle shape bent from the upper flange 110 to the web 120. The reinforcing angle 140 preferably has an L-shaped cross section and an angular shape in terms of workability and safety Do.

The reinforcing angle joint 142 is formed at the joint where each reinforcing angle 140 abuts when the two H-beams 100 are connected. That is, referring to FIGS. 1 and 9 (b), when the two H. beams 100a and 100b provided with the reinforcing angle 140 are laterally connected, the reinforcing angles 140a and 140b The cross section is the reinforcing angle joint 142.

The H-beam connection work performed at the construction site includes welding the reinforcing angle joint 142 (step s2). That is, the reinforcement angle joint 142 is field welded, and the scallop 143 may be formed to perform V-groove welding as shown in FIG.

The inner angle of the reinforcing angle space 144 formed by joining the reinforcing angle 140 to the upper flange 110 and the web 120 may be filled with the angle inner filler 150 as described later. 10, the other end of the reinforcing angle joint portion 142 is formed so as not to flow down to the opposite end of the reinforcing angle 140, that is, the opposite end of the reinforcing angle joint portion 142, So as to separate the reinforcing-angle inner space 144 from each other.

The angle filling material 150 is inserted into the reinforcing angle inner space 144 by the reinforcing angle 140 so as to primarily reinforce the connecting portion by the reinforcing angle 140, 150 are hardened, stress can be borne. This method can also prepare for cases in which the structural safety due to welding defects in step s2 can not be secured.

The step of filling (filling) the inner filler 150 is performed after the field welding step s2 of the reinforcing angle joint part 142 is performed. 11, a filler input port 111 is formed so as to penetrate from the upper side of the upper flange 110 to the lower reinforcing angle internal space 144, and the inside of the reinforcing angle interior space 144 through the filler input port 111 The filler 150 is charged (step s3).

The inner filler 150 is hardened and solidified after a predetermined period of time in a liquid state that can be introduced into the filler inlet 111, and examples thereof include concrete. It is desirable to use non-shrinkage concrete in order to prevent deformation due to shrinkage particularly when it hardens.

FIG. 7 is a graph showing a stress test result of the H Beam connection portion provided with the reinforcing angle, and FIG. 8 is a graph of a stress examination result of the H Beam connection portion filled with concrete in the reinforcing angle inner space. In FIGS. 7 and 8, the stress load state by the reinforcing angle 140 and the stress load state by the inner filler 150 that is concrete can be confirmed.

The main features of the present invention described above are based on a connection structure in which a joint plate 160 is attached to the web 120 and the lower flange 130 and fastened by the high tension bolt 170 as shown in FIGS. . Which will not be described in detail. However, the web 120 or the seam iron plate 160 and the high tension bolt 170 of the lower flange 130 may be omitted according to the required specifications.

The present invention has the following effects.

By reinforcing the stress of the mold connecting part by providing the connecting part reinforcement angle weldable at the site, it is possible to reduce the material cost and the construction cost by eliminating the intermediate pile construction, and it is advantageous in shortening the construction period and improving the construction efficiency.
