Slab panel beam support guide for construction {GUIDE FOR SUPPORTING SLAB PANNEL BEAM OF BUILDING CONSTRUCTION}

The present invention relates to a beam support guide that is slidably mounted on a supporter to support a slab panel during the construction of a concrete slab of a building, and allows the length of the beam support guide to be adjusted so that the position or presence of the handle pin of the slab panel beam can be adjusted. Regardless, it relates to a slab panel beam support guide for construction so that the support and guide of the slab panel beam can be made smoothly.

In general, recent building formwork is mainly composed of a panel assembly made of a metal material such as iron or aluminum, and the wall formwork is a unit formed in a rectangular shape with an upper and lower length relatively large compared to the width with an interval equal to the thickness of the wall to be constructed. It is assembled by successively joining wall panels to cover the area of the wall, and the slab formwork is a rectangular unit slab panel continuous on a single plane between a supporter erected vertically from the floor and beams supported on the top of the wall formwork. It is arranged so that it constitutes a supporting floor surface for pouring concrete.

When the wall formwork and slab formwork are installed, the concrete is poured into the formwork and the formwork is dismantled when curing is completed. Therefore, in order to dismantle the slab panel, the separated slab panel falls to the floor by its own weight in the process of separating and dismantling the connected and assembled panel using a ladder, and in the process, damage to the panel made of metal and safety accidents Of course, due to the noise and dust generated in the process of collision with the floor surface, it has acted as a factor deteriorating not only the construction site but also the surrounding environment.

As a measure to solve the above problems raised in the formwork construction method applied in the existing building construction, Korean Patent Registration No. 10-0484512 discloses that the formwork is dismantled after the concrete pouring and curing for forming walls and slabs through the formwork is completed. Therefore, the beam structure for supporting the slab panel was improved so that the slab panel does not fall directly from the ceiling to the floor and is supported in a lowered state so that the operator does not need to use a ladder, so that the operator can directly lift the panel to the floor. A new method of constructing a formwork for slab construction has been disclosed.

The formwork for slab construction of the above patent solves all the problems pointed out in the existing formwork at once, and it can be easily and quickly dismantled without requiring special skill to install and dismantle the formwork while minimizing damage to the panel. Due to the advantage of being able to promote work, the so-called "drop construction method" in the related industry has been continuously expanded as an eco-friendly formwork construction method, which is used in the construction of high-rise buildings including apartments.

According to the trend of activation of the 'drop construction method', the technology related to the same method is also developed in parallel. A technology is disclosed in which a slab panel support beam mounted rotatably descends along a tie rod, and a slab panel also descends together. A method of dismantling the formwork is known so that the slab panel moves downward along the supporter while maintaining the horizontal state by separating it.

On the other hand, Figures 1 and 2 will be respectively an exploded perspective view and a cross-sectional view of the combined state of the building slab construction apparatus using the drop construction method disclosed in Laid-Open Patent Publication No. 10-2019-0114731. As shown, at the top of the supporter 102 supported from the bottom to be easily separated from the slab panel beam 101 when the formwork is dismantled, it is connected in a straight line with the slab panel beam 101 through the fixing piece 103 The prop head 104 is mounted with a stop key 105, and below it, a beam support guide 106 that guides the support and sliding of the slab panel beam 101 is detachably mounted, and the slab panel and The descent of the slab panel beam 101 by its own weight is configured to be stopped by a stopper 108 fixed on the supporter 102 through the stiffening member 107 provided in the beam support guide 106 . Unexplained symbols P and S are pins and springs, respectively.

In the slab construction device of the drop accomplice, the beam support guide 106 uses the pin insertion holes 106a formed at the wing ends extending outward from both sides of the slab panel beam 101. The pins formed in the fixing pieces 103 located on both sides of the slab panel beam 101. In a state in which the insertion hole and the pinhole formed in the slab panel beam 101 are accurately aligned to form a straight line, the pin P is fastened to have these through-holes, and the slab panel beam 101, the prop head 104, and the beam support guide The coupling between the members fixing between (106) is made.

By the way, in a state in which the beam support guide 106 made of aluminum as the heavy object, the slab panel beam 101, and the beam support guide 106 are accurately aligned at a considerable vertical distance from the ground, the slab panel beam 101 is The work of penetrating and fastening the pin P between the fixing pieces 103 located on both sides is difficult, and in some cases, the interference of the handle pin for transporting the slab panel beam makes it impossible to mount the beam support guide. There is a need for improvement.

The present invention is to solve the problems of the prior art, so that the wing length of the beam support guide can be adjusted so that the support and sliding guide for the slab panel beam can be made regardless of the position or presence of the handle pin formation of the slab panel beam. It is an object of the invention to provide a slab panel beam support guide for construction.

Another object of the present invention is that the wings of both sides of the beam support guide are in contact with the handle pins of the slab panel beam in a state in which they are not coupled with the pins passing through the fixing piece, or in a floating state without contacting any part of the beam. It is to provide a slab panel beam support guide for construction to be combined with the prop head of the supporter.

It is to provide a slab panel beam support guide for construction that can be mounted on the outer peripheral surface of the supporter under the prophead regardless of the pin.

The above and other objects of the present invention are coupled in a straight line on both sides of a prop head coupled to the upper end of a supporter erected vertically from the floor to guide the downward sliding of the slab panel beam supporting the slab panel. In the guide, the beam support guide comprises a pair of guide bodies formed symmetrically to each other and mounted on the outer circumferential surface of the supporter, wherein each guide body includes a mounting body mounted on the outer periphery of the supporter, and upward from the mounting body. A vertical connection portion that extends, a horizontal extension portion extending outward in the horizontal direction from the upper end of the vertical connection portion, a variable wing that is slidable along the upper surface of the horizontal extension portion and has an upwardly curved outer end, and the variable wing separates from the horizontal extension portion It is achieved by a slab panel beam support guide for construction, including a wing guide to slide in a non-doing state.

The pair of guide bodies are, for example, a detachable guide structure in which one side of the mounting body is hinged and the other side is mounted on the outer periphery of the supporter by fastening of a fastener. The part is equipped with a resilient member that is elastically installed by a spring, so that the supporter and the beam support guide are in elastic contact. The resilient member includes a friction member head making frictional contact with the outer circumferential surface of the supporter by the elastic force of the spring, and a fixing rod extending from the friction member head and fixed to the reinforcing member seating portion with the spring interposed therebetween.

Next, the variable wing slidably along the upper surface of the horizontal extension portion of the guide body is preferably formed to have approximately the same width as the horizontal extension portion, and a locking jaw is formed at the inner end so that the locking jaw is caught on the wing guide, so that the variable wing is formed. configured to prevent escape.

The wing guide consists of a tunnel portion forming a sliding groove for the passage of the variable wing between the upper surface of the horizontal extension portion and a fixing portion fixed to the bottom surface of the horizontal extension portion by welding or the like. In this case, the upper and lower widths of the sliding grooves are larger than the thickness of the variable wings and smaller than the thickness of the locking jaws.

On the other hand, all members constituting the slab panel beam support guide of the present invention are preferably formed of aluminum.

According to the present invention, as the wing length of the beam support guide can be adjusted, the support and sliding guide for the slab panel beam can be made regardless of the position or presence of the handle pin formation of the slab panel beam. There is an advantage that slab construction of the drop method can be performed by using various existing slab panel beams with different positions as they are.

In addition, in the present invention, both sides of the variable wings of the beam support guide are in contact with the handle pins of the slab panel beam in a state in which they are not engaged with the pins passing through the fixed piece, or in a floating state without contacting any part of the beam. By combining with the prop head of can be done easily.

First, Figure 3 is an exploded perspective view of a slab panel construction apparatus including a beam support guide of an embodiment of the present invention, Figure 4 is a perspective view of a beam support guide according to an embodiment of the present invention.

As shown in Figure 1, the beam support guide 10 according to the present invention is fixed pieces 30 on both sides of the prop head 21 coupled to the top of the support 20 like the conventional slab construction apparatus for the drop method. and the slab panel beam 30, which is connected in a straight line through the fixing pin P, is slidably mounted on the outer periphery of the support 20 under the slab panel beam, and is separated from the prop head 21 after curing of the slab concrete is completed ( 40) and the slab panel supported thereon (not shown) is configured to be gradually descended along the support 20 in a state of being supported.

The beam support guide 10 is made by combining a pair of guide bodies 10A and 10B formed symmetrically to each other, wherein each guide body 10A, 10B is a mounting body portion mounted on the outer periphery of the supporter 20 . (11), a vertical connection portion 12 extending upwardly from the mounting body portion 11, a horizontal extension portion 13 extending outward in the horizontal direction from the upper end of the vertical connection portion, and along an upper surface of the horizontal extension portion It is slidable and consists of a variable wing 14 having an upwardly curved outer end and a wing guide 15 for guiding the variable wing in a state that does not deviate from the horizontal extension 13 .

The pair of guide bodies 10A and 10B has a structure in which one side of the mounting body 11 is hinged and the other side is mounted on the outer periphery of the supporter 20 by fastening the fastening piece 16, at this time The arming member seating part 17) formed between the mounting body 11 and the outer circumferential surface of the supporter 20) is equipped with a stiffening member 18 that is resiliently installed by a spring (S), and the supporter 20 and the beam support guide (10) remains in elastic contact. The stiffening member 18 extends from the friction member head 18a making frictional contact with the outer circumferential surface of the supporter by the elastic force of the spring S and the friction member head with the spring interposed therebetween. It is configured to include a fixed rod (18b) located on.

Next, the variable wing 14 sliding along the upper surface of the horizontal extension portion 13 of the guide body 10A, 10B is formed to have substantially the same width as the horizontal extension portion, and a locking protrusion 14a is formed on the upper surface of the inner end portion. As a result, the locking jaw is caught on the wing guide 15 so as to prevent separation of the variable wing 14 and limit the variable length.

The wing guide 15 is a fixed part fixed to the lower surface of the horizontal extension part by welding or the like and a tunnel part 15b having a sliding groove 15a for passage of the variable wing between the upper surface of the horizontal extension part 13 and the lower surface of the horizontal extension part. (15c) is included. In the drawings, unexplained reference numeral 22 is a stop key, reference numeral 23 is a stopper, and reference numeral 41 is a handle pin.

On the other hand, Figure 5 is a cross-sectional view of the coupled state of the device of Figure 3, based on this, looking at the coupled state of the drop method slab construction apparatus using the beam support guide 10 of the present invention is as follows.

Typically, the slab panel beam and the prophead are connected and fixed by a pair of fixing pieces commonly fastened to the prophead, the slab panel beam, and the beam support guide.

However, there are cases where the handle pin 41 is formed on the slab panel beam, and the handle pin 41 causes interference, making it impossible to mount the beam support guide. Just supposing this case, the beam support guide 10 of the present invention avoids the interference of the handle pin 41 through the length adjustment of the variable wing 14, and as shown in FIG. 5, the fixing piece 30 and the pin (P) ) to couple the beam support guide 10 to the prop head 21 and the slab panel beam 40 on both sides thereof. At this time, the pin insertion holes on both sides of the fixing piece 30 and the corresponding pinholes of the slab panel beam 40 are formed at appropriate positions in consideration of the above circumstances.

That is, in the present invention, regardless of the position where the handle pin 41 is formed on the existing slab panel beam 40, the beam support guide is mounted through the length adjustment of the variable wing 14 of the beam support guide 10. to make it run smoothly.

Next, Figure 6 is a cross-sectional view of the state in which the prophead and the beam are separated in the apparatus of Figure 5. After curing of the slab concrete is completed, the dismantling process of the slab construction apparatus by the drop method using the apparatus of the present invention is as follows same.

First, the slab panel beam 40 is separated from the prophead 21 , and the separation between these two members is achieved by removing the pin P inserted into the central pinhole of the fixing piece 30 .

As such, at the moment when the slab panel beam 40 is separated from the prophead 21, the slab panel assembly starts to descend on the supporter 20 by its own weight. In the state in which the stop key 22 is mounted, the lowering of the slab panel assembly is started by applying a blow to the stop key so that the prop head 21 moves from the small diameter part to the large diameter part of the stop key.

As shown in FIG. 6, the descent of the slab panel assembly is performed in a state in which the slab panel beam 40 is supported by the fixing piece 30 and the beam guide 10, and is in elastic contact with the outer circumferential surface of the supporter 20. It descends gradually while avoiding a sudden drop by the frictional force applied from the member 18, and this descent proceeds stably while the wide flat slab panel assembly is in a horizontal state without tilting to either side or disturbing the assembly state. do.

The lowering of the slab panel assembly is stopped as the bottom surface of the beam support guide 10 comes into contact with the stopper 23 on the supporter 10 . At this time, the operator removes the coupling pin between the slab panels without using a separate ladder to separate the slab panel and put it down on the floor.
