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 and supports a slab panel during construction of a concrete slab of a building, wherein a fixing pin is inserted through a fixing piece connecting the slab panels on both sides of the prop head in a straight line. In addition to being provided with a ball, the length of the beam support guide can be adjusted so that the slab panel and the support guide can be smoothly supported by only the support guide without the slab panel and the support guide being fixed by the fixture, if necessary. Building slabs that enable smooth support of beams It relates to a panel beam support guide.

In general, recent building formwork is mainly composed of an assembly of panels made of metal materials such as iron or aluminum. Wall formwork is a unit formed in a rectangle with a relatively large vertical length compared to the width at intervals equal to the thickness of the wall to be constructed. It is assembled by continuously combining wall panels to cover the area of the wall, and the slab formwork is composed of rectangular unit slab panels continuous on a single plane between a supporter erected vertically from the floor and beams supported on top of the wall formwork. Arranged so as to constitute a support floor for concrete pouring.

After the wall formwork and slab formwork have been installed, concrete is poured into the formwork and the formwork is dismantled when curing is completed. In most buildings, the height between the floor and the ceiling (floor height) exceeds the worker's height Therefore, in order to dismantle the slab panel, in the process of separating and disassembling the connected and assembled panels using a ladder, the separated slab panel falls to the floor due to its own weight, and in the process, damage to the panel made of metal and safety accidents In addition to the inevitable risk, the noise and dust generated in the process of collision with the floor has acted as a factor that deteriorates the environment as well as the construction site.

As a way 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 concrete for forming walls and slabs through formwork is placed and the formwork is dismantled after curing is completed. Therefore, the slab panel support beam structure is improved so that the slab panel does not fall directly from the ceiling to the floor and is supported while descending to a height that does not require the operator 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 also, without requiring special skills in installing and dismantling the formwork, it is easily and quickly dismantled while minimizing damage to the panel. Due to the advantage of being able to promote work, the so-called "drop construction method" is named in the related industry, and as an environmentally friendly formwork construction method, construction using this method has been continuously expanding in the construction of high-rise buildings including apartments.

In accordance with the activation trend of the 'drop construction method', technology related to the method is being developed in parallel. As a few examples, Patent Registration No. 10-1127008 has one side on the slab corner bracket at the top of the wall panel. In the process of the rotatably mounted slab panel support beam descending along the tie rod, a technology is disclosed in which the slab panel also descends together, and in Patent Registration No. 10-1491074, the yoke supported by the slab panel is As it is separated, a method of dismantling the formwork is known so that the slab panel moves downward along the supporter while maintaining a horizontal state.

On the other hand, Figures 1 and 2 are an exploded perspective view and a cross-sectional view of the combined state of the building slab construction device using the drop construction method disclosed in Patent Publication No. 10-2019-0114731, respectively. As shown, the top of the supporter 102 supported from the bottom surface is connected in a straight line with the slab panel beam 101 through the fixing piece 103 so that it can be easily separated from the slab panel beam 101 when the formwork is dismantled. The prop head 104 to be is mounted together with the stop key 105, and the beam support guide 106 for guiding the support and sliding of the slab panel beam 101 is detachably mounted below it, and the slab panel and The descent by the weight of the slab panel beam 101 is configured to be stopped by the stopper 108 fixed on the supporter 102 through the waning 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 accompaniment, the beam support guide 106 has pin insertion holes 106a formed at the ends of the wings extending outward on both sides of the slab panel beam 101. Pins formed on the fixing pieces 103 located on both sides 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, fasten the pin P to have these through holes so that the slab panel beam 101, the prophead 104, and the beam support guide (106) The coupling between the members fixing them is made.

By the way, the slab panel beam 101 in a state in which the beam support guide 106 made of aluminum as the heavy material, the slab panel beam 101, and the beam support guide 106 are accurately aligned at a position away from the ground at a considerable vertical interval It is difficult to penetrate and fasten the pins (P) between the fixing pieces 103 located on both sides, and in some cases, the interference of the handle pins for transporting the slab panel beam makes it impossible to mount the beam support guide. There is a need for improvement.

In addition, depending on the work site, the existing supporter and the prop head are coupled to the top, and the slab panel beam is coupled to both sides of the prop head, and the pin is fastened through the fixing piece and the beam support guide to break the assembly method. Thus, the assembly method of combining the supporter and the beam support guide at the lower end of the prophead in a state in which the prophead using the fixture and the slab panel beam on both sides are combined in a straight line and placed over the upper ends of both side walls is It seems to be advantageous, but it is impossible without a change or improvement of the conventional beam support guide and the prophead and slab panel beam assembly structure combined therewith.

Another object of the present invention is to contact the handle pin of the slab panel beam in a state where both wings of the beam support guide are not coupled with the pin passing through the fixture, or even in a floating state without contact with any part of the beam It is to provide a slab panel beam support guide for construction to be combined with the prophead of the supporter.

Another object of the present invention is to provide a support piece having a pin hole through which a pin passing through the fixing piece passes on both wings of the beam support guide, so that the fixing of the beam support guide and the slab panel beam by the fixing piece and the pin in the conventional manner In some cases, both wings of the beam support guide are in contact with the handle pins of the slab panel beam or do not contact any part of the beam, and support the slab panel beam in a floating state. It is to provide a slab panel beam support guide for construction.

Another object of the present invention is to combine the slab panel beams on both sides of the prophead to form a straight line using a fixing piece and a pin fastened to it, regardless of the beam support guide, and place it across the top of the wall panel on both sides of the prophead. It is to provide a building slab panel beam support guide that can be assembled in a manner in which a supporter body and a detachable beam support guide are mounted at the bottom.

It is configured to prevent departure.

The wing guide is composed of a tunnel portion forming a sliding groove for 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. At this time, the vertical width of the sliding groove is formed to a size larger than the thickness of the variable wing and smaller than the thickness of the locking jaw. When the support piece installed on the upper surface of the wing guide is formed by welding, for example, the pinhole formed in the support piece is for inserting a pin passing through the slab panel beam and the fixing piece, through which the existing fixing method beam A fixed coupling is made between the support guide and the fixing piece and the slab panel beam.

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