Description

Construction method of reinforced concrete structure using triangular stud frame

The present invention relates to a construction method of a reinforced concrete structure using a triangular stud frame that can be easily and conveniently constructed without installing a copper bar.

Reinforced concrete construction method, commonly called RC (Reinforced Concrete) structure, is one of the most commonly encountered construction methods. , mainly applied to wall structures such as high-rise apartment houses.

The construction of such a reinforced concrete structure proceeds in the process of completely hardening the concrete after the formwork is installed, the concrete is poured, and the concrete is cured for a certain period of time.

At this time, the formwork is firmly supported by using the dongbari, and when curing is completed, it is removed together with the dongbari.

Therefore, the conventional construction of a reinforced concrete structure cannot avoid the inconvenience of having to install and remove a number of formwork and copper bars one by one, and accordingly, the construction period is lengthened.

In particular, in the construction of conventional reinforced concrete structures, when large space structures such as distribution warehouses are constructed, the height of the floor is high, making it difficult to install the formwork and pillars, and the risk of safety accidents increases. As it increases, the problem arises that the construction cost is greatly increased accordingly.

As shown, the construction of the reinforced concrete structure using the triangular stud frame of the present invention is performed on the floor surface A step of vertically installing a triangular stud frame (S1), a step of constructing a reinforced concrete wall using the triangular stud frame (S2), and a step of installing a noise prevention structure between floors crossing the opposite reinforced concrete wall ( S3), and constructing a deck plate for a slab on the upper portion of the interlayer noise prevention structure (S4), and constructing a reinforced concrete slab using the deck plate for the slab (S5).

Hereinafter, the construction method of the reinforced concrete structure using the triangular stud frame of the present invention will be described in detail.

2 is a view sequentially showing the process of constructing a reinforced concrete wall surface according to the construction method of a reinforced concrete structure using a triangular stud frame according to the present invention, and FIG. 3 is a cross-sectional view taken along the line III-III in FIG. 4 is an exploded perspective view of FIG. 3 , and as shown, first, a triangular stud frame 100 is vertically installed at regular intervals on the floor surface. (S1)

The triangular stud frame 100 applied at this time is the first stud body 110 and the second stud body 120, and the connection bracket 130 for mutually coupling the first stud body 110 and the second stud body 120 to each other. ) can be composed of

The first stud body 110 includes a first plane 111 facing the interior, a pair of first inclined surfaces 112 adjacent to the left and right ends of the first plane 111, and each first A first connecting portion 113 formed of a pair of parallel flanges extending from the end of the inclined surface 112 to the outside is provided.

In addition, the second stud body 120 includes a second plane 121 facing the outdoor side, a pair of second inclined surfaces 122 adjacent to the left and right ends of the second plane 121, and an indoor space. A second connection portion 123 formed of a pair of side-by-side flanges extending to protrude to the side is provided.

The first stud body 110 and the second stud body 120 configured in this way can be molded and manufactured to form a triangular shape as a whole through bending processing such as bending and roll forming of a zinc steel sheet, respectively.

Meanwhile, at least one or more strength reinforcement beads 114 and 124 may be formed on the first stud body 110 and the second stud body 120 .

The strength reinforcement beads 114 and 124 are the first stud body 110 and the second stud body due to the compressive and torsional loads in the vertical direction acting on the first stud body 110 and the second stud body 120 . (120) to prevent the decrease in strength.

The connection bracket 130 is composed of a flat plate made of a steel material, and both ends are respectively inserted between the first connection parts 113 and the second connection parts 123, and fastening means such as screws, bolts, nuts, or rivets. is firmly fixed through

Meanwhile, the first stud body 110 may include a first rail portion 115 formed in the vertical direction at the center of the first plane 111 .

A first fixing member 150 capable of fixing the composite panel A for a wall is coupled to the first rail part 115 .

In this case, the first fixing member 150 includes a coupling bolt 151 fitted with a head portion to the first rail portion 115 so that the screw portion protrudes, and a first adjacent first fixing member 150 fitted into the screw portion of the coupling bolt 151 . A horizontal connection bar 152 connecting the first plane 111 of the stud body 110 and the screw portion of the coupling bolt 151 are fastened to the first horizontal connection bar 152 and the coupling bolt 151 It may be composed of a nut 153 fixed to the plane 111 .

It goes without saying that through-holes 152a should be formed at both ends of the horizontal connecting bar 152 so that the screw part of the coupling bolt 151 can pass therethrough.

The first fixing member 150 configured in this way inserts the coupling bolt 151 into the rail unit 140 , and then inserts the through-holes 152a formed at both ends of the horizontal connection bar 152 into the threaded portion of the coupling bolt 151 . After inserting the nut 153 to the screw portion, it is possible to easily fix the horizontal connecting bar 152 to the first plane 111 in such a way that it is firmly tightened.

On the other hand, the same rail unit 240 as the above-described rail unit 140 may be formed in the second stud body 120 as well, and a second adjacent second stud unit 150 is used in the same manner as the above-described first fixing member 150 . The stud body 120 may be connected to each other.

The triangular stud frame 100 configured in this way has a higher compressive strength in the cross-sectional structure than the "C"-shaped cross-section, so it can be applied to the frame of a multi-story structure that receives a relatively high vertical load or the frame of a structure with a high floor height. .

When the triangular stud frame 100 as described above is installed vertically on the floor surface at regular intervals, the reinforced concrete wall surface (W) is constructed without using a formwork panel or a copper bar supporting it using the triangular stud frame 100 (S2)

The reinforced concrete wall (W) using the triangular stud frame 100 is constructed in the following way.

First, reinforcement (not shown) is reinforced between the facing triangular stud frames 100 . At this time, the communication and electricity related cables (C) are installed between the triangular stud frames 100 and then discharged to the upper end of the triangular stud frame 100 . Then, using the first fixing member 150 on the inner side and the outer side of the triangular stud frame 100 facing the wall composite panel (A) is installed.

The composite panel for wall (A) is a panel in which a metal material such as aluminum is used as a surface material and an interior material having excellent thermal insulation and waterproof properties is disposed and adhered therein. Since it is commonly used in the market, a detailed description thereof will be omitted.

Such wall composite panels (A) are installed in such a way that the interior materials are inserted into the inner side of the triangular stud frame 100 so that the surface material is flush with the inner and outer surfaces of the triangular stud frame 100 .

In consideration of the cross-sectional shape of the triangular stud frame 100, the composite panel A for the wall has an inverted trapezoidal cross-section, and due to this cross-sectional shape, it does not deviate from the triangular stud frame 100 without a separate fixing member.

In addition, since the horizontal connection bar 152 supports the outer surface of the composite panel A for the wall, the composite panel A for the wall can maintain a stable installation state, When the composite panel (A) is fixed to the horizontal connection bar (152), the composite panel (A) for the wall is not at all concerned about being separated from the triangular stud frame (100).

Therefore, since screw holes are not formed in the first stud body 110 and the second stud body 120, the first stud body 110 and the second stud body are caused by the installation of the composite panel A for the wall. (120) no decrease in strength.

In this way, since the composite panel (A) for the wall is directly and firmly fixed to the inner and outer surfaces of the triangular stud frame 100 through the first fixing member 150, a separate supporting member such as a formwork or a copper bar is required. not required

Therefore, when installing the composite panel (A) for the wall, it is not necessary to bring in and install a separate support member such as a formwork or a copper bar to the workplace, thereby greatly improving workability and cost, and greatly shortening the construction period. Not only can it be done, but it can also greatly reduce the risk of safety accidents.

When the installation of the composite panel (A) for the wall is completed, concrete is poured between the composite panel (A) for the wall and cured for a predetermined time.

This completes the construction of the reinforced concrete wall (W).

5 is a view showing a state in which a reinforced concrete slab is constructed according to the construction method of a reinforced concrete structure using a triangular stud frame according to the present invention, and FIG. 6 is a cross-sectional view of FIG. 5, as shown, a reinforced concrete wall surface ( When the construction of W) is completed, the inter-floor noise prevention structure 200 is installed on the upper part of the facing reinforced concrete wall (W). (S3)

The inter-floor noise prevention structure 200 includes a plurality of upper support bars 210 having both ends fixed to the opposing reinforced concrete wall W, and each upper support in a state where both ends are fixed to the opposing reinforced concrete wall W. The vibration damping pipe 220 installed in the vertical lower part of the bar 210, the upper connecting member 230 vertically connecting the upper support bar 210 and the vibration damping pipe 220, and the neighboring vibration damping pipe ( 220) to the left and right, and both ends on the opposite reinforced concrete wall (W) so as to be arranged in a triangular shape around the vibration damping tube 220 together with the upper support bar 210 and the upper support bar 210 This is fixed and the lower support bar 250 to which the ceiling finishing member (B) is fixed to the bottom surface, the lower connection member 260 for connecting the vibration damping tube 220 and the lower support bar 250 by the shortest distance, and each lower branch It may be composed of a connecting bar 270 attached to the upper end of the jiba 250 and the lower end of each upper support bar 210 to connect the lower support bar 250 and the upper support bar 210 in a triangular shape.

In this case, the connecting bar 270 includes a first connecting bar 271 connecting the lower supporting bars 250 and the upper supporting bar 210 and the lower supporting bar 250 together with the first connecting bar 271 . It may be composed of a pair of left and right second connection bars 272 connecting the two in a triangular shape.

Through the connection bar 270, the upper support bar 210 and the lower support bar 250 can achieve a solid ceiling structure while greatly improving structural safety.

In the interlayer noise prevention structure 200 having such a configuration, the upper support bar 210 and the lower support bar 250 are installed after the vibration damping tube 220 and the vibration damping tube connecting member 240 are installed first. Then, the installation of the upper connecting member 230, the lower connecting member 260, and the connecting bar 270 is completed in this order.

When the installation of the inter-floor noise prevention structure 200 is completed, the deck plate 300 for the slab is installed on the upper support bar 210. (S4)

Since the installation of the deck plate 300 for the slab is a state in which the upper support bar 210 is firmly fixed to the reinforced concrete wall W, there is no need to install a separate support member such as a dongbari on the floor surface.

Therefore, when the deck plate 300 for the slab is installed, the inconvenience and effort of bringing in and installing a separate support member such as a formwork panel or a copper bar to the workplace is not followed, which greatly improves workability and cost, and greatly reduces the construction period. Not only can it be shortened, but the risk of safety accidents can be greatly reduced.

On the other hand, the deck plate 300 for the slab is fixed to the upper end of the interlayer noise prevention structure 200 and may be composed of a plurality of steel plates 310 continuously connected through a lock shim 311, each steel plate 310 . A second rail portion 312 is formed on the second rail portion 312, and a second fixing member 320 capable of fixing a raceway (R) or ceiling facilities such as a sprinkler or a gas alarm. can be inserted and combined.

Since the steel plates 310 are connected through the lock shim 311, the tensile force is greatly improved and it is possible to stably withstand the load of the concrete poured from the top.

In addition, between the deck plate 300 for the slab and the upper end of the upper support bar 210, a vibration-proof member 330 capable of absorbing the vibration transmitted to the upper support bar 210 when an impact occurs from the upper layer is preferably installed. .

In this case, in the center of the upper surface 101 of the upper support bar 210, an insertion groove 211 into which the insertion protrusion 111 of the vibration-proof member 330 is fitted, and the insertion groove 211 downward toward the bottom. An extended space portion 211a may be provided.

Therefore, the impact generated in the reinforced concrete slab (S) of the upper layer is transferred to the vibration-proof member 330 and then converted into an impact sound using the air of the space portion 211a as a medium, and this impact sound is generated within the space portion 211a. As it is diffusely reflected, most of it is canceled and is not transmitted to the lower layer.

In this way, when the installation of the deck plate 300 for the slab is completed, the reinforced concrete slab ( S) is completed. (S6)

If necessary, a floor cushioning material is laid on the reinforced concrete slab (S), lightweight foam concrete is poured on the floor cushioning material, and after a curing process for a certain period of time, hot water/heating pipes are installed on the upper part of the lightweight foam concrete at regular intervals. The process of curing by pouring and curing the finishing mortar may be further performed.

After that, the second fixing member 320 is fitted and coupled to the second rail part 312 , and then various firefighting facilities installed on the raceway R and the ceiling using the second fixing member 320 (not shown). to install Various communication and power cables (C) drawn from the reinforced concrete wall (W) are wired to the raceway (R).

And, when the ceiling finishing member (B) is fixed to the bottom surface of the lower support bar (250) and the reinforced concrete wall surface (W) is finished with interior materials and wallpaper, etc., construction of a reinforced concrete structure using the triangular stud frame 100 of the present invention This is done.

If it is desired to construct a multi-layer reinforced concrete structure, the above-described process may be repeated with the constructed reinforced concrete slab (S) as the floor surface.

In this case, when constructing the deck plate 300 for the slab, various communication and power cables C drawn from the reinforced concrete wall W are deployed to the upper portion of the deck plate 300 for the slab. Although not shown, a cable passage hole is additionally formed in the deck plate 300 for the slab.

In this way, various communication and power cables (C) in the lower layer are exposed from the bottom surface of the reinforced concrete slab (S) that has been constructed, and in this way, various communication and power cables (C) are easily deployed from the lower layer to the upper layer. can

The reinforced concrete structure using the triangular stud frame 100 of the present invention constructed as described above has a characteristic in which the impact sound generated from the reinforced concrete slab S of the upper floor is reduced due to the noise prevention structure 200 between floors.

That is, when the impact (F) is generated in the reinforced concrete slab (S) of the upper layer, the impact (F) passes through the vibration-proof member 330 through the reinforced concrete slab (S) to the upper support bar ( It is transmitted to the vibration damping pipe 220 installed closest to the point of impact through the 210 and the upper connection member 230 .

As a result, the vibration damping tube 220 receives an impact in the form of a pressing force from the upper portion, and moves down minutely due to the impact.

When the corresponding vibration damping tube 220 moves downward, the neighboring vibration damping tubes 220 are given an upward force through the vibration damping tube connecting member 240 , and this upward force is applied to the corresponding vibration damping tube 220 . ) to reduce the descending force.

On the other hand, the lowered vibration damping tube 220 is moved upward, and in this process, the neighboring vibration damping tubes 220 are given a downward force through the vibration damping tube connecting member 240, and this downward force is The lifting force of the vibration damping tube 220 is reduced.

At this time, the lower connection members 260 help the vibration damping tubes 220 to stably vibrate up and down while holding the lower portions of the vibration damping tubes 220 with uniform force from both sides.

As such, the vibration damping tube 220 and the neighboring vibration damping tube 220, which received an impact from the reinforced concrete slab (S) of the upper floor, vibrate in opposite directions to each other, and the impact transmitted from the reinforced concrete slab (S) of the upper floor is attenuated.

On the other hand, when prestress is introduced into the vibration damping tube 220 in the circumferential direction, the vibration damping tube connecting member 240 is given a tensile force, so that the ascending and descending force for the vibration damping tube 220 is effectively reduced. will lose

Here, when the vibration damping tube connecting member 240 is connected to the vibration damping tube 220 with different connection parts in the upper and lower directions according to the prestress introduction direction of the vibration damping tube 220, neighboring vibration dampening By promoting the generation of a moment of resistance in the tube 220, the reduction of the ascending force and the descending force for the vibration damping tube 220 is more effectively made.

On the other hand, the impact from the reinforced concrete slab (S) of the upper layer that is not completely attenuated by the vibration damping pipes 220 is converted into an impact sound using air as a medium, and this impact sound is the reinforced concrete slab (S) and the ceiling finishing member (B) Most of them are canceled as they are diffusely reflected in the space between them.

Therefore, in the lower floor, the impact sound generated in the upper floor is not transmitted, so that it is possible to maintain a quiet indoor environment.

As such, although the preferred embodiment of the present invention has been described above with reference to the drawings, the present invention is not limited to the above-described embodiment, and a person of ordinary skill in the art to which the present invention pertains can modify it without departing from the spirit of the present invention.
