The present invention relates to a gangform for the construction of open structures, and more particularly to a gangform for the construction of open structures to prevent the fall of the gangform used when constructing the walls of open structures such as balconies, railings and the like. will be.

In general, to construct high-rise buildings, such as apartments and buildings, large formwork made of steel, that is, gang forms are used. The gang forms are steel forms installed on the outside, cages on which work spaces are installed, and inner gang forms on the outer walls. It is used to construct walls using a number of parts such as tie bolts for fixing the outer steel form and john bolts for fixing the gang form. As such, a plurality of gangforms are used to construct the outer wall of the entire building, and one gangform is a large structure having a weight of about 3 to 4 tons and having a height of about 9 m. These gangforms are pulled up to the upper floor using tower cranes.The hooks of the tower cranes are connected to the lifting rings of the gangforms, then the dismantling bolts at the bottom of the gangforms are dismantled and pulled up to fix the lower part of the gangforms with the anchor bolts. Construction of the outer wall is repeated.

In this process, the lifting bolts are often dismantled due to the operator's mistake before the hook of the tower crane to the lifting ring of the gang form in the process of raising the gang form to the upper floor. It is true.

In addition, when the hook of the tower crane is connected to the lifting ring of the gang form, the lifting process may also impact other adjacent gang forms under the influence of wind, and may damage the fall bolt of the gang form that is impacted. There are also various types of accidents, such as accidents that occur.

This quotation is to prevent the fall of the gang form, even if the gang form is removed from the concrete due to the operator's arbitrary dismantling of the lower part of the gang form or breakage of the fixing bolt. Even if the lifting ring is damaged, there is an effect of preventing the fall of the gangform, but this is to prevent the fall of the gangform only after the completion of the construction and curing of the structure below the stopper (30), below the stopper (30) If the lower part of the anchor bolt fixing the gangform 1 before the construction and curing of the structure is broken, or if the worker's fault or the anchor bolt is broken, the gangform 1, which is a heavy object, is dropped and the seating part 20 ) Is hit by the already cured structure of the lower floor, and after falling, it continues to fall and cause damage to people and property. .

The purpose of the present invention is to solve the problems as described above,

When the construction gangform is raised to construct the open structure, the gang form for the open structure construction is formed so that the interlocking portion is automatically protruded from the middle part of the gang form corresponding to the cured lower layer to form a support structure that is caught on the balcony or the railing. It is to offer.

The present invention is fixed to a number of frames in front, rear and left and right to solve these problems, and to secure the working space by fixing the support and the mesh on the side and bottom of these frames, and fastened to the balcony of the structure In the known gangform consisting of a plurality of bounce bolts and the base support base,

Vertical bars fixed in conjunction with the vertical frame of the gangform for construction of open structures with balconies or balustrades, hangers that protrude at an acute angle to the vertical bars and span the jaws of the balconies or balustrades, and one end of the hangers is at the top of the vertical bars. Rotating shaft to be coupled to the rotating shaft, springs to be coupled to the rotating shaft to be automatically projected by the resilience, and vertical to ensure that the interlocking latch is balanced without losing power It is provided with a horizontal bar fixed between the bar and the locking bar, and a limit bar and an end plate for restricting the locking bar from protruding at an appropriate interval.

Accordingly, the present invention prevents the fall of the gang form even if the gang foam is removed from the concrete due to breakage of the slab buried in the lower part of the gang form or breakage of the retaining bolt by the worker. In addition to reducing human and property damage, it is also effective in eradicating industrial accidents at economic cost.

The first embodiment of the gangform for construction of open structures of the present invention is described in detail with reference to FIGS. 3 and 4 as follows.

As shown here, by installing the support and the footrest 113 on the side and bottom of the plurality of horizontal or vertical frame 103 and the vertical frame 103 to provide a working space 114, fastening to the balcony of the structure In the well-known gangform 102 composed of a plurality of bounce bolts 112, etc., by the spring 108 in the middle of the vertical frame 103, which is a portion that is in contact with the structure, such as a balcony or handrail of the cured lower floor of the structure It has been provided with a latching section 104 that elastically protrudes forward, a vertical bar 101 and a horizontal bar 106 integrally connected with the latching section 104.

Accordingly, the other end of the horizontal bar 106 in the present invention is connected to the lower end of the locking section 104, and the vertical bar 101, the locking section 104, and the horizontal bar 106 form a triangle as a whole. The bar 106 is inclined by slightly heightening the height of the vertical bar 101 side rather than the interlocking 104 side, so that the gang form 102 and the balcony are secured by the interlocking 104 in a more stable state when the gang foam 102 falls. And handrails to be supported.

In addition, the rotating shaft 107 for allowing the locking rod 104 and the horizontal bar 106 to be integrally coupled so that the fixed vertical bar 101 is coupled with the vertical frame 103 of the gang form 102 to be rotated. And, one end is supported on the vertical frame 103, the other end is supported on the rotating shaft 107, the other end is a spring 108 for supporting the locking interval 104 so that the locking interval 104 can protrude by itself by elasticity ) Is provided. In addition, the end bar 109 is to be caught in the vertical bar 103 to the rear of the vertical frame 103 to limit the locking bar 104 is not protruded more than necessary while rotating the vertical bar (101).

Referring to the operating state according to the first embodiment of the present invention as follows. In high-rise buildings such as apartments, the horizontal bar 106 with the hanging rail 104 protruding above the balustrade or balustrade completed in the open spaces such as balconies and balustrades is located, and then the gangfoam in the process of constructing the wall surface. Concrete is poured into the space formed using the 100 and the internal formwork, and when curing is completed, the upper end of the gang form is hooked to the hook of the tower crane, and then the dismantling bolt 112 installed at the lower part is dismantled and the hook of the tower crane is lifted. The gangform is to be lifted to the upper layer, and in this process, the bracket 100 passes between the cured walls together with the gang foam 102 as shown in FIG. 5.

That is, in the present invention, the interlocking protrusion 104 that protrudes with the elasticity of the spring 108 comes into contact with the structure, and the gangform 102 continues to rise in this state, as shown in FIG. 5, as shown in FIG. 5. Overcoming the elasticity of the coupled spring 108 and pivoting about the pivot shaft 107, the locking section 104, the horizontal bar 106, the vertical bar 101 is retracted to the rear, thereby the bracket 100 is It can pass through the walls of the structure without difficulty. In this way, when passing through the wall, the latch 104, the horizontal bar 106, the vertical bar 101 is projected again as shown in Figure 4 by the elasticity of the spring 108, so that the horizontal bar 106 of the structure It will be located above the railing. In this state, the fixing bolt 112 is fixed, and concrete is placed in a space formed by applying a formwork to the inside as described above, and curing is completed. In the above-described process, the mounting bolt 112 and the coupling 116 are connected. When the slab of the anchor bolt 117 that is fastened and buried by) is broken or the anchor bolt 112 is broken, or when the anchor bolt 112 is dismantled before hanging the crane again to lift the gang form to the upper layer, etc. When this occurs, the gang foam 102 is separated from the construction wall to fall to the ground, in the present invention, in this case, the horizontal bar 106 falls and caught on the construction 105 constructed as a balcony or railing, and further falls Not doing so will prevent serious life and property damage.

In other words, in the present invention, the horizontal bar 106 is about 10 cm above the construction 105, and when the drop situation falls only about 10 cm, it is caught by the construction 105 immediately. It was.

 In such a state, the entire gangform 102 is supported by the supporting section 115 below the gangform 102 together with the horizontal bar 106, thereby preventing the gangform from falling down in a stable state.

 In addition, where there is a height of the construction 105 in an open space such as a railing, as shown in FIG. 7 according to the second embodiment of the present invention, at the lower end of the interlocking 104 of the bracket 100 It can be carried out in the form having a vertical locking step 110 formed.

Accordingly, the vertical locking jaw 110 vertically installed at the lower portion of the locking section 104 is positioned above the construction 105, and in this state, as described above, the gangform 102 is moved to the position bolt 112. Fixed and performs a series of operations for the construction of the wall on the upper floor, even if the situation that the gang foam 102 falls in this process, the vertical locking jaw 110 is caught on the construction 105 so that the gang foam does not escape Since the fall of the 102 is prevented, safety construction becomes possible.

In addition, another third embodiment of the present invention is shown in FIG.

As seen therein, the bracket 100 of the present invention manages the height of the ceiling or floor of a building to be constructed by a plurality of the gang foam 102 and the bracket 100 installed to construct a single floor. In order to provide a height adjustment bolt 111 at the lower end of the vertical bar (101).

That is, according to the third embodiment of the present invention, this is to manage the height of the floors of the building to be installed by installing the gang foam 102, the lower floor when forming the floor by pouring concrete in the construction of high-rise building If an error occurs due to mismanagement of the floor height from the floor to the floor of the upper floor, the height of the building will not be constant as it goes to the upper floor, and the height of the whole building will be greatly increased when the error is accumulated and reaches the top floor. It is going to escape. In order to prevent this from happening so that the interlayer height is constant, the left and right heights of the gangform will be enabled by adjusting the height adjusting bolts 111 on one side of the horizontal bar 106 of the bracket 100. This is to turn the height adjustment bolt 111 for each bracket 100 in the state that is installed in the gang foam (102) by placing a constant distance between the bottom of the bolt 111 and the bottom or railings of the structure each floor As the height of the floor becomes horizontal as a whole, it is possible to make all the heights constant by applying the same height while moving to the upper floor.

In this way, the present invention is a whole construction process, such as the breakage of the slab embedded with the anchor bolt fixing the gangform lower part, or the operator dismantles the anterior bolt before the gangform is hooked to the hook of the tower crane, or the anterior bolt is broken. The gangform can be prevented from falling and falling from the wall of the open structure throughout, preventing valuable loss of life and property, while the bracket for this structure is simple and low in manufacturing cost, so it is widely available. There is a useful effect to be done.
