Description

{TENSION REINFORCED DECK SLAB STRUCTURE} Composite deck slab structure for civil engineering and construction purpose which is easy to fabricate camber using synthetic material and synthetic material connected with shift part.

The present invention relates to a tensile-reinforced steel composite deck slab structure, and more particularly, to a tensile reinforced steel composite deck slab structure that increases the rigidity of a bottom section slab and a connection slab formed on both sides of the alternation section, and a tensile stiffener that supports the slabs by a tensile force. And a composite deck slab structure, which is compositely connected to an alternate portion pile foundation which can prevent a flexural deformation of a floor slab, and which is easy to manufacture a camber using a reinforcing material.

Generally, a deck slab structure of a raymen structure (bridges, buildings, etc.) is composed of a slab, a wall and a foundation, and the fulcrum portion where the slab and the wall are connected to each other is a raymen bridge of a reinforced concrete material connected by a rigid body. As a result of increasing the cross section to resist the load acting on the structure itself, the increase of the dead load, the reduction of the space of the bridge, and the increase of the cross section increase due to the increase of the dead load In general, slab-type structures are used only for short bridges (roughly within 18 meters of bridge), and general structures using girders or boxes that are generally applied for long bridges are used, There are many limitations in applying structures to the field. Has emerged.

In addition, although the raymen structure is advantageous in that it can be constructed economically because of its simple structure, it is relatively simple in construction, and in order to resist the load acting on the structure itself, the cross section of the slab or the like is increased In particular, there is a problem in that the strength of the cross section is increased and the force is not distributed smoothly. In general, the rheme structure can not be used only for the short structure.

And it is necessary to reduce the bending moment of the continuous slab and to take measures to reinforce the end and center tensile force at the place where the long span is needed.

According to this necessity, Patent Document 1 (Patent Registration No. 10-0989313) by the present applicant is available.

[ Wow; A lower stiffening plate 160 forming a bottom of the steel composite slab 150; And a reinforcing member for supporting the lower reinforcing plate 160.

Here, the tensile reinforcement 170 may be applied. The tensile reinforcement 170 is embedded in the steel composite slab 150 and reinforces the steel composite slab 150 through a tensile force. The tensile reinforcement 170 may be installed on the upper surface of the lower reinforcement plate 160, So that the floor slab 130 can be prevented from sagging. The tensile stiffener 170 may be integrally installed over the connecting slab 140 -the bottom slab 130-the connecting slab 140 as a whole and may include a section of the connecting slab 140-the bottom slab 130, (130) -connecting slab (140).

Alternatively, as shown in FIG. 2A, the tensile reinforcement 170 may be configured such that the portions of the shift portions 110 and 120 are installed higher than other portions (fixing ends) through the direction changing member 180. That is, the direction changing material 180 is installed at a position higher than the bottom portion of the bottom slab 130 and the connecting slab 140 at the upper portion of the shift portions 110 and 120 so that the tensile stiffener 170 can be moved The bottom slab 130 and the connecting slab 140 are downwardly sloped about the ash 180 and fixed to effectively prevent deflection of the bottom slab 130 due to the tensile force. At this time, the tensile stiffener 170 may be installed at each of the alternating portions 110 and 120, or may be installed at various positions along the wiring direction from the connecting slab 140 to the connecting slab 140 at the other side .

FIG. 2B shows an example in which a girder-type stiffener 600 (specifically described below) is applied to the bottom of the bottom slab 130, and the alternating portions 110 and 120 and the bottom slab 130 are installed through the anchor bars. The girder-type stiffener 600 is fixed to the bottom surface of the lower stiffener 160 by welding or the like to reinforce the bottom slab 130, and it is possible to use an I beam, an H beam, an angle, a tensile material, or the like.

FIG. 1 can be applied when the ground is short, and FIGS. 2A and 2B can be applied when the ground is long.

The alternating sections 110 and 120 are built up with a certain distance from each other and are embedded in the ground so that a part thereof protrudes to the ground and support the steel composite slab 150 at the bottom. And concrete wall portions 112 and 122 laid in the pile portions 111 and 121, respectively. Although the alternate portion 110 is shown as applied with the PHC file and the alternate portion 120 is shown as applied with a steel pipe file in the drawing, it is to be appreciated that the alternate portion is not necessarily shown as such, FIG.

3 and 4, the file portions 111 and 121 of the PHC file are reinforcing means provided in the concrete piles 111a and 121a and the concrete piles 111a and 121a, respectively, which are hollow, and the reinforcing beams 111b and 121b (For example, H beam), reinforcing beams 111b and 121b, and concrete that is inserted into the studs 111c and 121c, the bending reinforcing bars 111d and 121d, and the concrete piles 111a and 121a.

The studs 111c and 121c and the bending reinforcing bars 111d and 121d may be alternately arranged repeatedly in the longitudinal direction on the reinforcing beams 111b and 121b and the bending reinforcing bars 111d and 121d may be arranged alternately 111b and 121b and the studs 111c and 121c may be provided in multiple stages on both sides of the connection between the reinforcing beams 111b and 121b.

The reinforcement means may be formed entirely inside the concrete piles 111a and 121a but may be installed only in a part of the concrete piles 111a and 121a because it can be sufficiently reinforced even if it is installed only in a portion subjected to a large load, The concrete piles 111a and 121a can be installed by horses or the like and the reinforcing means can be installed inside the concrete piles 111a and 121a. Alternatively, after the reinforcing means is installed in the concrete piles 111a and 121a (in a condition where the concrete is not laid), the concrete piles 111a and 121a can be installed by hovering.

After the pile sections 111 and 121 are installed, the pile sections and the head part of the pile sections 111 and 121 can be augmented to be combined with the concrete wall sections 112 and 122.

Anchor means or the like embedded in the concrete wall portions 112 and 122 are connected to the upper portions of the pile portions 111 and 121 to increase the composition of the pile portions 111 and 121 and the concrete wall portions 112 and 122.

As shown in FIG. 5, the anchor means may be, for example, an H-beam anchor bar 113 or 123 in order to facilitate binding with the file units 111 and 121 using a PHC file.

The above-described studs and reinforcing bars can be applied to the anchor bars 113 and 123 as well.

The anchor bars 113 and 123 are connected to the reinforcing beams 111b and 121b embedded in the concrete piles 111a and 121a through the connecting members 114 and 124. [ As shown in the drawing, the coupling members 114 and 124 have grooves that enclose the reinforcing beams 111b and 121b and the anchor bars 113 and 123. Two connecting beams 114 and 124 are disposed symmetrically with respect to the reinforcing beams 111b and 121b and the anchor bars 113 and 123 It can be installed with bolting together.

The anchor bars 113 and 123 have a function of composing the pile portions 111 and 121 and the concrete wall portions 112 and 122 as well as a function of firmly combining the alternating portions 110 and 120 and the bottom slab 130 integrally, The anchor bars 113 and 123 are embedded in the concrete wall portions 112 and 122 so as to penetrate the concave portions or the convex portions of the lower reinforcing plate 160 and are fixed to the lower reinforcing plate 160. The fixing of the anchor bars 113 and 123 and the lower reinforcing plate 160 is performed by fixing a pair of fixed angles 118 and 128 welded and fixed on the lower reinforcing plate 160 and welded to the anchor bars 113 and 123 Lt; / RTI >

It is preferable that two or more anchor bars 113 and 123 are provided on the concrete wall portions 112 and 122. The anchor bars 118 and 128 may be fixed to the anchor bars 113 and 123 without fixing the anchor bars 113 and 123 to the lower reinforcement plate 160, The anchor bars 113 and 123 and the lower reinforcing plate 160 can be further strengthened in that they can be fixed together.

The anchor bars are not limited to the above-described structures, and anchor rods that are embedded in the concrete wall portions 112 and 122 alone without being connected to the pile portions 111 and 121 are also possible.

The tensile reinforcement member 170 is connected to the pile portions 111 and 121 and integrated with the steel composite slab 150 to serve as an anchor bar bearing the force transmitted in the throttle direction.

The tensile reinforcement 170 can be made of steel bars, steel rods, or stranded wires, and can be selected according to the structural stability depending on the structure.

When the tensile stiffener 170 is installed through the direction changing material 180, as shown in Fig. 7, the direction changing material 180 is applied.

The direction changing member 180 is firmly fixed to the shift portions 110 and 120 while smoothly switching the wiring direction of the tensile stiffener 170. For example, the tensile stiffener 170 may be formed in a circular shape, The wiring grooves 181 are provided so as not to be stably inserted.

A plurality of reinforcing bars 115 and 125 may be installed to set the direction changing material 180 at a position higher than the bottom of the bottom slab 130 and the connecting slab 140. [ The reinforcing bars 115 and 125 may be bent, for example, in a "U" shape so that both ends are fixed to the pile portions 111 and 121 while wrapping the direction changing material 180.

The concrete wall portions 112 and 122 are formed by putting the concrete in the periphery of the pile portions 111 and 121 using the pile portions 111 and 121 as core materials.

For example, there is a method of forming a hole for the construction of the concrete wall portions 112 and 122 in the ground, providing the pile portions 111 and 121 in the lower ground of the hole by hammers, etc., and placing the concrete to form the concrete wall portions 112 and 122 The alternating portions 110 and 120 can be constructed.

On the other hand, when the alternation height is large and alternation conduction is anticipated, the rear portions of the shift portions 110 and 120 are back-filled during the process of constructing the shift portions 110 and 120, and the shift portions 110 and 120 are pushed forward It is not possible to firmly back-fill the rear portions of the shift portions 110 and 120. This causes voids in the rear of the shift portions 110 and 120, which may result in the loss of the ground, and as a result, 9 and 10, in order to solve this problem, it is possible to prevent the conduction of the conduction parts 110 and 120 and the collapse of the structure. In order to solve this problem, in the bottom part of the alternation parts 110 and 120, i.e., the concrete wall parts 112 and 122, (116, 126) are formed. The conduction preventing portions 116 and 126 protrude toward the ground at the bottom of the concrete wall portions 112 and 122. The conduction preventing portions 116 and 126 prevent conduction of the alternating portions 110 and 120 as backfilling is performed at the upper portion.

In order to prevent the movement of the shift portions 110 and 120 and the bottom slab 130, an activity prevention wall 141 for supporting the side surfaces of the shift portions 110 and 120 is provided on the lower surface of the connection slab 140, 600 may be provided with an activity-preventing key 630 for supporting the sides of the shift portions 110, 120 to help prevent the turnover of the shift portion. The activity-preventing key 630 is not limited to being formed only on the girder-type stiffener 600, but may also be formed on the bottom of the lower stiffener 160 without the girder-type stiffener 600.

Wings 117 and 127 may be formed on the left and right sides of the shift portions 110 and 120, respectively. The wing walls 117 and 127 are integrally formed so as to be arranged at right and left sides of the left and right sides of the concrete wall portions 112 and 122 to exert a compressive force against the earth pressure.

It is preferable that the wing walls 117 and 127 are integrally formed with the underside of the conduction preventing portions 116 and 126.

The wing walls 117 and 127 are reinforced concrete structures and can be integrally combined with the connecting slabs 140 in addition to being connected to the alternating sections 110 and 120 and are supported in the form of anchor bars to maximize the rigidity of the structure The connecting reinforcing bars 117a and 127a (the connecting reinforcing bars are laid in such a manner that a part thereof is projected outside the wing walls 117 and 127 as reinforcing bars to be laid in the wing walls 117 and 127, 127 and the connecting slab 140 by inserting the connecting slabs 140 so that the connecting reinforcing bars 117a and 127a are embedded in the connecting slabs 140 140) are integrally synthesized.

The steel composite slab 150 functions as a continuous beam shape in which the bottom slab 130 and the connecting slab 140 function as a continuous beam with respect to the alternating portions 110 and 120 located at the inner bottom from both ends, And a cantilever structure supported on the ground with reference to the sections 110 and 120.

When the steel composite slab 150 is installed to be supported on the alternating portions 110 and 120 in such a continuous beam shape, the longitudinal bending moment (-M1) acting on the steel composite slab 150 acts on the right side portions of the conventional structure And the bending moment of the continuous slab is relatively reduced when the steel composite continuous slab structure according to the present invention is applied to the present invention. In addition to the effect that the bending moment of the continuous slab is relatively reduced, The reinforcement of the tensile force (bending moment) makes it possible to construct a more stable and economical structure.

The lower reinforcing plate 160 also functions as a reinforcing member for increasing the sectional rigidity of the steel composite slab 150 and a function of the mold of the bottom slab 130.

The lower reinforcement plate 160 can have various shapes such as a concave-convex section, a horizontal section without concavity and convexity, or an arch-shaped section. In the case of the concave-convex section, the flexural rigidity can be increased. It is possible to effectively transfer to the units 110 and 120 and enhance aesthetics.

As shown in FIG. 10A, the lower reinforcing plate 160 may be shifted by shifting both sides of the lower reinforcing plate 160 by placing the lower reinforcing plate 160 on the alternating portions 110 and 120 at the construction site, The upper and lower reinforcing plates 160 and 160 are welded to each other so that the upper and lower reinforcing plates 160 and 160 are welded to each other. So that the lower reinforcing plate 160 with the line load can be installed. After the lower reinforcing plate 160 is bent in a convex shape upward, the reinforcing plate 160 is fixed to the lower reinforcing plate 160. That is, the stiffener will be cut in advance to match the curvature of the lower stiffening plate 160.

Alternatively, as shown in FIG. 10B, a downward load may be applied to the left and right sides of the longitudinal reinforcing plate 160 at the center of the plant to curvature, and the curvature of the curved lower reinforcing plate 160 It is also possible to fix the pre-cut stiffener to give the pre-load.

The lower reinforcing plate 160 is fixed to the alternating portions 110 and 120 on both sides in the longitudinal direction (for example, fixed by anchor means by the above-described method).

Since the lower reinforcing plate 160 having such a structure has a flexural rigidity because of the concavo-convex structure, the structure of the lower reinforcing plate 160 makes it difficult to cover the load of the bottom slab 130, and thus uses a stiffener.

11A and 11B) vertically installed on the recess 161 or the convex portion 162 of the lower stiffening plate 160. The reinforcing plate 160 is supported on the concave or convex portion of the lower stiffening plate 160, (FIGS. 12A and 12B) and a reinforcing beam of an I-shaped cross section (FIGS. 13A and 13B) are used, and any one or two or more of them can be used in combination.

11A and 11B, the reinforcing plate 200 is erected at right angles to the recess of the lower reinforcing plate 160 and the bottom of the reinforcing plate 200 is fixed to the lower reinforcing plate 160 by welding or the like, Thereby preventing warpage deformation.

The reinforcing plate 200 has a hole or shear through which the plate member or the shear connection reinforcing bar 131 having the height up to the bottom of the shear connecting reinforcing bars 131 buried in the bottom slab 130 and the upper portion of the lower reinforcing plate 160, It may be a plate having a groove opened upward so that the connecting reinforcing bar 131 is fitted from above. When the reinforcing plate 200 and the shear connection reinforcing bars 131 are connected to each other as described above, the reinforcing plate 200 can be integrated with the concrete portions of the shear connecting reinforcing bars 131 and the bottom slab 130 There are features.

The reinforcing plate 200 may also have an L-shaped cross-section in which a horizontal portion is provided in which the reinforcing plate 200 is in surface contact with the concave portion of the lower reinforcing plate 160 in order to increase rigidity and increase adhesion.

12A and 12B, the reinforcing angle 300 of the T-shaped section is formed on the bottom portion of the concave portion of the lower stiffening plate 160 and is fixed to the vertical portion 310 and the vertical portion 310 And a horizontal portion 320 formed at a right angle to the upper portion.

The vertical portion 310 of the reinforcing angle 300 of the T-shaped section may be formed with a hole for receiving the shear connection reinforcing bars 131.

As shown in FIGS. 13A and 13B, the reinforcing beam 400 of the I-shaped cross section is formed by a beam (H beam, I beam or the like) having an I-shaped cross section on the basis of a state where the reinforcing beam 400 is installed on the concave portion of the lower reinforcing plate 160, And is fixed to the concave portion of the lower reinforcing plate 160 by welding or the like.

Although not shown in the drawing, a beam 400 having an I-shaped cross section may be formed with a hole through which the shear connection reinforcing bars 131 are inserted and received.

Although the reinforcing member 200 (the reinforcing plate 200, the reinforcing angle 300 of the T-shaped section and the reinforcing beam 400 of the I-shaped section) is shown only in the recess of the lower reinforcing plate 160, It can be applied to both the lumbar part and the convex part, and it can also be applied to the bottom part of the lumbar part as a girder type. 14A and 14B, the girder-type stiffener 600 is installed on the bottom of the lower stiffening plate 160 and is provided on the lower surface of the lower stiffening plate 160 (Fig. 14A) And a bottom portion 620 formed at a right angle to the bottom of the vertical portion 610 and supported on the upper surface of the shift portions 110 and 120. The vertical portions 610 and the bottom portions 620, According to the girder-type stiffener 600, since void spaces are formed between the lower reinforcing plate 160 and the alternating portions 110 and 120, the concrete should be laid through the cover plate or the like after the closing.

14C to 14E, when the girder-type stiffener 600 is installed under the lower stiffener 160, the girder stiffener 600 is fixed to the alternating portion (welding, bolting, etc.) 600 can be fixed without changing its position, and the hinge portion can be constructed so that the girder-type stiffener 600 can be naturally mounted to the bolting and welding positions.

The hinge portion includes a hinge protrusion 113a having a semicircular cross section and provided at an upper portion of the anchor bar 113 and a semicircular hinge protrusion 113a disposed at a bottom portion 620 of the girder stiffener 600 so as not to protrude to the bottom of the bottom portion 620. [ And a hinge groove 621 formed in a cross section and into which the hinge protrusion 113a is inserted.

The hinge protrusions 113a and the hinge grooves 621 are formed by curved plates of two semicircular sections formed by cutting steel pipes. Of course, any one of the hinge protrusions 113a is required to be inserted into the hinge grooves 621 to change the curvature by bending.

A fixing plate for fixing the hinge protrusion 113a may be formed on the upper portion of the anchor bar 113. The fixing plate may be a bolt hole so as to be bolted to the girder-type stiffener 600 together with the fixing of the hinge protrusion 113a.

In the right-angled part with the hinge part of this structure, only the post-synthesis load and the vehicle live load are loaded, and a small amount of reinforcing bar and a little concrete are required in the right corner.

The anchor bar connecting plate 113b can be applied to facilitate the installation of the anchor bar 113 in the portion where the girder-type reinforcement 600 is not connected and to facilitate the position determination.

The anchor bar connecting plate 113b has a hole of a size that allows the anchor bar 113 to pass therethrough and can be fixed to the anchor bar 113 through the fixed angle 118. [

15A and 15B are views showing another configuration of the lower reinforcing plate and the reinforcing member. The lower reinforcing plate 160 has a structure in which a recess 163 and a horizontal portion 164 of a semicircular section are alternately repeatedly formed, And a supporting stiffener 500 formed at a lower portion of the concave portion 163 of the stator.

The concave portion 163 and the horizontal portion 164 of the semicircular section of the lower reinforcing plate 160 are preferably formed together with a stud to be combined with the concrete portion.

The supporting stiffener 500 increases the rigidity of the lower stiffening plate 160 and supports the lower stiffening plate 160 while being supported by the ground. The supporting stiffener 500 includes a pair of legs 163 supported by a recess 163 having a semi- And a horizontal bottom portion 520 connected to the bottoms of the legs 510 and the legs 510.

The backing stiffener 500 is not limited to being applied to recesses of a semicircular section and is also applicable to recesses of other types of sections.

The stiffener (the reinforcing plate 200, the reinforcing angle 300 of the T-shaped section and the reinforcing beam 400 of the I-shaped section) described above can be integrally formed with the concrete portion of the bottom slab 130, .

Although the lower reinforcing plate 160 and the stiffener are described as being single pieces, the lower reinforcing plate 160 and the stiffener may have a single structure.

For example, as shown in FIGS. 16A and 16B, the lower reinforcing plate 160 is a combination of the bottom portion 165 and the reinforcing portion 166, and the bottom portion 165 and the reinforcing portion 166 are alternately repeated Lt; / RTI >

The bottom portion 165 may be a flat single-sided cross-section, or may be a channel having vertical portions 165a on both sides, as shown in the figure.

For example, the reinforcing portion 166 is a beam of an I-shaped cross section and is welded and fixed while the horizontal portion thereof is placed on the vertical portion 165a of the bottom portion 165. [

That is, the reinforcing portion 166 may have any shape as long as it has a connecting portion 166a connected to the bottom portion 165 and a vertical reinforcing portion 166b for preventing warpage.
