Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a form support structure for a backhoe construction method having a column unit support structure,

The present invention relates to an installation structure of a formwork support frame for constructing a horizontal structure such as a beam and a slab of a building, and more particularly, to a construction method of a horizontal structure of an underground structure by a back- And a method of constructing an underground structure using the same.

There are two types of methods to construct the underground structure: a tandem approach that constructs the trench first from the lowest tier, and a second tier that builds from the first tier to the lowest tier.

Among them, the backfilling method can construct the underground structure at the same time as the ground structure can be constructed by the sand bar, and the air is greatly reduced, and the bottom structure such as the boat or slab, which is constructed by the backhoe, supports the earth retaining wall. It is possible to secure a sufficient work space and to secure ease of construction and economical efficiency by reducing the amount of material used and it is possible to implement the most safely in the downtown area because the influence on adjacent buildings can be significantly reduced compared with other methods Is a public law.

In this backfilling method, concrete is installed to construct a horizontal structure such as a slab of a ground level by installing a support material after partially excavating the ground, and after completion of curing, the support material is removed, A cave is built for. However, the method of supporting the mold by the support material can not remove the support material until the concrete is cured and the subsequent culvert process can not be performed promptly.

Various non-supportive methods have been developed for solving these problems. For example, there have been developed a method of installing a non-supporting beam of the registered patent publication No. 10-0261775 called NSTD method, There is a method of pouring rainless reinforcements.

In the method of installing the solid support of Registration No. 10-0261775, it is possible to omit installation of the support material by supporting the form support frame as a suspension member. When the curing of the one-story horizontal structure concrete is completed, The upper end is fixed and both end portions of the form support frame are suspended at the lower end of the suspension member so that the support material is not installed at the lower portion of the form support frame.

When the concrete in the horizontal structure is cured, the form support frame and the suspension material are lowered to the lower layer using a stranded wire installed in the hydraulic jack.

In the method of installing a blank supporting member of Registration No. 10-0605514, a support bracket is installed on a column, and both end portions of a form support frame are supported by supporting brackets provided on two adjacent columns, so that a support material is installed at the bottom of the form support frame . In this case, when the concrete of the horizontal structure is cured, the bracket is lowered using the suspension material installed on each support bracket, and the form support frame is lowered to the lower layer.

The above-mentioned plain concrete pavement method is advantageous in that it can advance the construction work of the subsequent process even if the curing of the horizontal structure is not performed after curing the concrete since the support material is not installed at the lower part of the pillar support frame.

Meanwhile, since the large floor area of each floor needs to be broken in a unit of a certain area, the above-mentioned conventional method of installing the non-reinforced concrete pavement is a method in which the form support frame is installed in units of spans between two adjacent pillars, The descent of the formwork support frame also has to be done in units of span between the column and the column.

1 is a plan view for explaining the disassembly of the form in units of spans in the method of placing the non-rectangular reinforcement of Registration No. 10-0605514.

For this purpose, the support brackets installed on one column are composed of two sub brackets, and these sub brackets are fixed to the columns while being coupled to each other to support the form support frame.

However, as shown in FIG. 1, in order to descend the form support frame only for an area of one span unit and dismantle the form, one sub-bracket supporting the adjacent span among the pair of sub-brackets installed on the column is fixed to the column So that it is necessary to perform a separate operation for maintaining the fixed state of the one sub-bracket.

In order to lower the form support frame to remove the form, the four sub-brackets supporting the four corners of the form support frame must be lowered together. So that it is practically not easy for all of them to have the same descending speed.

However, if there is a difference in descending speed between the sub-brackets of each of the tabs supporting the plan-shaped formwork support frame, not only deformation occurs in the form support frame, but also the yoke joints installed thereon are distorted. There is a problem that additional effort and time are required.

In addition, since the work of removing the form must be performed simultaneously with respect to the entire area of the span unit, there is a possibility that the workpiece is damaged, and the number of the downward supporting points requires a lot of holes in the slab, It has another problem.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. However, in order to obscure or obscure the technical idea of the present invention due to the detailed description of the known structure in describing the present invention, the description of the structure of the above known structure will be omitted.

3 is a plan view of the form supporting structure 10. FIG. 4 is a plan view of the form supporting structure 10 according to an embodiment of the present invention. Figure 3 is a front view of the form support structure (10).

The form supporting structure 10 of the present invention supports a concrete pouring form for constructing a horizontal structure such as a slab in a non-pouring manner when constructing an underground structure in a backward manner so that a subsequent process such as a hoisting operation can be rapidly performed 2 to 4, an integrated pillar bracket 110 installed on the pillar 30, a pillar support frame 120 supported by the integral pillar bracket 110, and a pillar bracket 110 And a support stand 130 that maintains its horizontal state while preventing sagging of the apparatus.

Unlike conventional brackets, the integral pillar bracket 110 is fixedly installed on the pillar 30 without being separated and integrated with the pillar 30. When the operation of the pillar 30 is completed, the integrated pillar bracket 110 descends to the position of the lower layer, do. That is, the integrated pillar bracket 110 of the present invention moves down the pillar 30 as a central vertical axis, and transfers the form load in each pillar 30 to the pillar 30.

The integrated pillar bracket 110 has an integral structure in which the pillar 30 is lowered with the pillar 30 as a central vertical axis. The shape of the integral pillar bracket 110 is not particularly limited as long as it has the same functions and effects. However, And includes a pair of horizontal beams 111 and a marginal rib 112 connecting both ends of the horizontal beams 111 to form a rectangular plane. For the sake of simplicity, this structure will be described as an example.

The pair of horizontal beams 111 are installed so as to be opposed to each other with respect to the column 30 so that the central portion of the entire length of the horizontal beam 111 is located at the center of the cross section of the column 30. At this time, between the horizontal beam 111 and the outer surface of the column 30, it is sufficient that the horizontal beam 111 slides on the column 30, but most preferably, the central portion is located on both outer sides of the column 30 Have interviewed so that there is no fluctuation due to separation.

However, the form support structure 10 may be easily assembled, or a predetermined space may be provided between the horizontal beam 111 and the outer surface of the column 30 so that it can be universally applied to various standard columns. In this case, it is possible to make the state in which the horizontal beam 111 and the outer surface of the column 30 are indirectly interviewed by using the movement control reinforcing plate 140, which will be described later.

The integrated pillar bracket (110) may further include a suspension support beam (113). The suspension support beam 113 serves as a fixing bracket at the lower end of the suspension member 20 so that the integrated pillar bracket 110 can be moved downward by suspension means such as a suspension member 20, And a lower portion of the pair of horizontal beams 111 are connected to each other. Of course, if the lowering of the integral column bracket 110 is performed by a method other than the suspension method, it is not necessary to construct the suspension supporting beam 113.

The support of the suspension by the suspension means has to balance the load around the column 30. The pair of suspension supports 113 are installed so as to be symmetrical with respect to the column 30.

The form support frame 120 which directly supports the dies 31 and 32 and is placed on the upper part of the integral pillar bracket 110 is fixed to the integral pillar bracket 110, And so on.

The form support frame 120 is placed at right angles to the upper surface of the horizontal beam 111 of the integral column bracket 110 and is fixed to the integral column bracket 110 so as to be integral therewith. And a main transverse rib 122 for connecting and fixing the pair of main ribs 121 to each other.

At this time, since the inner point of the skein 121 is placed and fixed on the upper surface of the horizontal beam 111, the horizontal beam 111 of the pillar bracket 110 and the skein 121 of the mine supporting frame 120 are fixed to the pillar 30 And both ends of the skein 121 have a shape protruding outward from the pillar 30. [0064] As shown in Fig.

The combined structure of the integral pillar bracket 110 and the mold support frame 120 is such that the inner point in the longitudinal direction of the form support frame 120 is located on the pillar 30, Since the mold supporting structure 10 is installed around a single pillar 30, at least four pillars are divided into a unit, so that the operation of installing and removing the formwork 5, it is possible to form a single column 30 as a center without affecting the adjacent column 30 as shown in FIG. 5, unlike the prior art, So that only the form support structure 10 of FIG.

As described above, the present invention has a structure in which both ends of the form support frame 120, more specifically both ends of the stem 121 protrude from the column 30 and are positioned between adjacent pillars 30 . At this time, the lengths of the center of the column 30 and both ends of the pitch 121 protruding therefrom may be symmetrical to each other as shown in FIG. 3, or may be asymmetric as shown in FIG. 6 . In addition, depending on the protruding length of the main beam 121, at least one of the opposite ends may be further provided with anti-twist stiffeners 123.

As shown in FIG. 6, when the protrusion length of the protrusion 121 is asymmetrical, when the downward movement of the form support structure 10 is suspended, a suspending support beam 113 is provided on the form support frame 120, It is preferable that the load is balanced with respect to all directions by being constructed to be supported at three points in a suspended manner together with two suspending support beams 113 provided symmetrically to the horizontal beams 111 of the integrated pillar bracket 110.

The suspension support beams 113 provided on the form support frame 120 are installed in such a manner that the lower portions of the pair of protrusions 121 are connected to each other at the position of the protruding portion of the protrusion 121.

Each of the form support structures 10 provided on the adjacent two columns 30 is structured so as to be capable of independently separating from each other without any special operation for mutual separation.

That is, as described above, the mold support structure 10 of the present invention is capable of independently descending only the pillar 30 regardless of the form support structure 10 of the adjacent pillar 30, . Therefore, no coupling means such as a bolt is used at all between the ends of two adjacent bosses 121 of each form support structure 10.

However, when the linearity is maintained between the respective form support frames 120 installed on the adjacent two columns 30, that is, when the respective blocks 121 maintain a straight line, the work of installing the form can be efficiently performed For this purpose, in another embodiment of the present invention, a connecting support beam 124 is provided at at least one end of both ends of the main beam 121.

7 and 8 are sectional views for explaining the shape of the connecting support beam 124 and FIG. 8 is a sectional view for explaining the shape of the connecting supporting beam 124, (121) are indirectly connected to each other to have a straight line.

The connection support beams 124 allow the main beams 121 of the adjacent form support frames 120 to be simply mounted so as to be slidable in the longitudinal direction so as to maintain a continuous straight line of the respective main beams 121, Allowing only the support structure 10 to descend.

The connection support beam 124 for this purpose is installed at the lower end of the end of the main beam 121 and a part of the connection support beam 124 protrudes outward so that the upper surface of the connection support beam 124 functions as a mounting surface for the end of the adjacent main beam 121.

At this time, a pair of guide plates 124a protruding upward can be further provided on both side surfaces of the connection support beam 124. [ This guide plate 124a allows the end of the adjacent pitch 121 to be accurately mounted on the upper surface of the connecting support beam 124. [ In addition, the guide plate 124a can have a shape that gradually widens toward the outside. This makes it possible to efficiently and easily perform an operation of mounting the end of the adjacent bobbin 121.

The integrated pillar bracket 110 integrally coupled to the form support frame 120 is fixedly supported by the support fixture 130 and transfers the upper load to the pillar 30. [ 9 is an exploded perspective view showing an embodiment of a support fixture 130 fixedly installed between the column 30 and the integral column bracket 110. As shown in FIG.

The support fixture 130 may be of a structure that can easily disassemble and efficiently transfer the load of the form support structure 10 to the column 30, but in the most preferred embodiment, as shown in FIG. 9, An upper hinge bracket 131A provided on the marginal rib 112 of the bracket 110, a lower hinge bracket 131B provided on the outer surface of the column 30, and an upper hinge bracket 131A and a lower hinge bracket 131B And a slanting bar 132 installed between the pillar 30 and the integral pillar bracket 110 to provide a brace reinforcement structure.

As shown in FIG. 6, depending on the load of the form support structure 10, the support fixture 130 may be installed on both sides of the column 30, but when the load acts largely, As shown, two columns 30 can be installed on both sides.

The upper and lower hinge brackets 131A and 131B are composed of a hinge plate 133 attached to the column 30 and the marginal rib 112 and a connecting rod 134 connected to an end of the inclined bar 132, There is no difference in that the connecting rod 134 is pinned to be rotatable with respect to each hinge plate 133. [ It is preferable that the lower hinge bracket 131B provided on the outer surface of the column 30 is formed as a pin connection structure that can easily separate the hinge plate 133 and the connecting rod 134 from each other. For example, in the case where the hinge plate 133 of the hinge bracket 131B and the connecting rod 134 are constructed of a detachable bolt fastening structure, Since the fixed state of the structure 10 is easily released, the lowering operation of the form support structure 10 is made easier.

In addition, in another embodiment of the support fixture 130, the length of the support fixture 130 is configured to be stretchable so as to have a function of correcting the horizontal state of the integral pillar bracket 110. One of the examples is that the connecting rod 134 and the end of the inclined bar 132 are connected by a screw tightening method so that the directions of fastening of the screws at the upper and lower ends of the inclined bar 132 are opposite to each other, The distance between the outer surface of the column 30 and the marginal ribs 112 and more specifically the distance between the upper hinge bracket 131A and the lower hinge bracket 131B is increased or decreased. Fig. 10 is a diagram illustrating the adjustment of the horizontal angle of the integral pillar bracket 110 by rotating the slope bar 132 in the support fixture 130 having such a structure and expanding its length.

A movement control reinforcing plate 140 may be further provided between the horizontal beam 111 of the integral column bracket 110 and the outer surface of the column 30. [

As described above, when the movable control stiffening plate 140 is formed with a predetermined gap between the horizontal beam 111 and the outer surface of the column 30, Thereby preventing the form support structure 10 provided in the frame 10 from easily moving or rotating at the set position and angle.

The movement control reinforcing plate 140 may be installed before the support fixture 130 is installed or after the support fixture 130 is installed according to the efficiency of the process or convenience of the operation.

For example, after the integrated pillar bracket 110 is lowered to the position of the lower layer by the suspension member 20 and the horizontal and the left and right angles of the integral pillar bracket 110 are adjusted in a suspended state in the suspension member 20, The integrated pillar bracket 110 is fixed to the column 30 by attaching the movement control reinforcing plate 140 between the horizontal pillar 111 of the pillar bracket 110 and the outer surface of the pillar 30, The support bracket 130 is installed between the column 30 and the integral column bracket 110 so that the integrated column bracket 110 can be fixed to the column 30 in a simple manner.

On the contrary, when the integrated pillar bracket 110 is set while the supporting pillar 130 on both sides of the pillar 30 is installed in a state in which the integrated pillar bracket 110 lowered to the position of the lower car layer is suspended by the suspension member 20 Position and angle between the horizontal pillar 111 of the integral pillar bracket 110 and the outer surface of the pillar 30 so that the integrated pillar bracket 110 adjusted by the unexpected impact does not move The movable control gusset 140 may be installed to fix the integral pillar bracket 110 to the pillar 30 as a whole.

The movement control stiffening plate 140 is fixedly attached to at least one of the outer surfaces of the horizontal beam 111 and the column 30. Together with the load acting on the form support structure 10, to provide the structural stability of the form support structure 10.

When the movement control reinforcing plate 140 is attached and fixed to the outer surfaces of the horizontal beam 111 and the column 30 together with the bolts fastened to the horizontal beam 111, So that the descending operation of the structure 10 can proceed easily.

Hereinafter, a method of constructing an underground structure in a backward manner using the dice supporting structure 10 described above will be described. A method of constructing an underground structure according to the present invention comprises the steps of: a) installing an earth retaining wall and a column (30); b) installing the form support structure (10); c) the step of installing the dies 31,32; d) casting and crushing of the concrete (C); e) lowering and reinstalling the form support structure (10); f) casting of under-floor concrete (C); g) completing each horizontal structure of the underground structure by a repetitive operation.

a) installing the retaining wall and the column (30);

After the earth retaining wall is installed on the periphery of the ground for constructing the underground structure, the column 30 for the vertical structure is installed in the ground inside the earth retaining wall.

b) installing the form support structure (10);

After the ground is pushed up to a part of the lower layer of the car, the above-described form support structure 10 is installed on the pillar 30.

In the case where the descent of the dummy supporting structure 10, which is performed after the completion of the construction work for the horizontal structure of the start layer, is planned to be carried out in a suspended manner, the suspending support beams 113 are provided on the integral column bracket 110, It is preferable to previously provide a member such as the sleeve 25 so that the fixed suspension member 20 can be positioned through the horizontal structure.

The integral pillar bracket 110 is fixed to the pillar 30 by means of a support fixture 130. The support fixture 130 can be configured to be stretchable in length, The operation of adjusting the horizontal state of the form support structure 10 by adjusting the length of the support fixture 130 during the installation work of the mold 10 can be performed together.

In addition, by providing the movement control reinforcing plate 140 between the horizontal beam 111 of the column bracket 110 and the outer surface of the column 30, the form support structure 10 can be firmly held in a fixed state . As described above, the movement control stiffening plate 140 may be installed first, and then the support staple 130 may be fixedly installed.

In addition, with respect to the form support structure 10 provided on the adjacent pillar 30, a connecting support beam 124 is provided at the lower end of the end 121, and the pillar 30 It is preferable to maintain the straightness of the continuous bobbins 121 by simply placing the ends of the bobbins 121 of the form support structure 10 provided at the ends of the bobbins 121 in a slidable manner.

This step is also performed in the lowering and reinstalling steps of the form support structure 10 described later.

c) the step of installing the formwork;

A main head formwork 31 is installed on the upper surface of the formwork support frame 120 with respect to the pillar 30 and a slab formwork 32 is installed between the main support formwork 120 and the formwork support frame 120 provided on the adjacent pillar 30 do.

The structures of the formers 31 and 32 are not particularly limited, but a deck having a reinforcing truss downward is preferably used. At this time, the main head form 31 and the slab form 32 are separated and separated from each other.

The main head form 31 separated from the slab form 32 may be fixed to be integrally formed with the form supporting frame 120. In this case, when the form supporting structure 10, which will be described later, Can be lowered together with the form support frame 120 while being naturally detached from the main head.

d) casting and crushing of the concrete (C);

A horizontal structure is constructed by simultaneously pouring the concrete (C) into the main head mold 31 and the slab mold 32. When the strength of the concrete (C) is developed to the extent that the horizontal structure can function as a stratum brace against the wall of the retaining wall due to the action of the steel film, the ground work is again carried out for the construction of the horizontal structure.

e) lowering and reinstalling the form support structure (10);

11 is a diagram illustrating the concrete structure of the concrete supporting structure 10 according to the present invention in the first stage of the concrete curing process. Reinstallation of the system.

After the curing of the concrete C is completed to such an extent that the horizontal structure of the starting layer can be self-supporting, after releasing the fixed state of the form supporting structure 10 fixed to the column 30, And re-installs it at the position below the column of the column 30. [

At this time, all the molds 31 and 32 of the horizontal structure may be removed together, but preferably only the main head mold 31 is removed in a state where the slab mold 32 is maintained, Together with the form support structure 10, as shown in Figure 11 (c).

The latter stepwise removal of the molds 31 and 32 of the horizontal structure prevents breakage of the molds 31 and 32 and at the same time as releasing the fixed state of the mold supporting structure 10 as described above, 31 are removed, the removal of the dies 31, 32 and the re-installation work on the lower layer can be performed quickly and efficiently.

The fixing state release of the form support structure 10 may be performed by a method of separating the hinge plate 133 of the lower hinge bracket 131B attached to the column 30, The bolts are loosened by a bolt-fastened structure between the connecting rods 134 so that the hinge plate 133 and the connecting rods 134 are separated as shown in FIG. 11 (b).

When the lowering of the form support structure 10 is completed, the support fixture 130 is installed in the same manner as in the step b), so that the form support structure 10 is fixed to the column 30. [

f) casting of under-floor concrete (C);

When the work for installing the horizontal structure is completed by installing the slab formwork 32 between the formwork support frame 120 provided on the adjacent pillar 30 and the concrete C is laid again on the horizontal structure, Build.

The installation of the slab formwork 32 may be accomplished in a manner that is immediately reinstated from the previous layer, but may be accomplished by using an extra slab formwork 32 prior to removal of the preceding slab formwork 32, May be shortened.

g) completing each horizontal structure of the underground structure in a repetitive operation;

The steps d) to f) are repeated to complete each horizontal structure of the underground structure.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the scope of the invention is not limited to the disclosed embodiments, but, on the contrary, It is obvious that it will be possible to carry out various modifications thereof.

For example, in the above-described embodiment, one form support structure 10 installed on one pillar 30 is independently installed and lowered, but a plurality of form support structures 10 installed in series or in parallel with each other, May be simultaneously installed and lowered.

FIG. 12 shows one example of such an arrangement, in which two formwork supporting structures 10 arranged in parallel can be lowered integrally with respect to each of the columns 30.

To this end, a connection suspension support frame 150 is further installed between the respective form support structures 10. The connecting suspension support frame 150 has a structural connecting function to allow the two formwork supporting structures 10 to be integrally installed and lowered while on the other hand, Thereby making it possible to omit the suspension supporting beams 113 installed in the structure 10. [ Of course, depending on the load size of the form support structure 10, the form support structure 10 may also be provided with a plurality of suspension supports 113 to have a plurality of suspension supports.

However, in this modification, the form supporting structure 10 is lowered independently of the pillar 30 alone regardless of the form supporting structure 10 of the adjacent pillar 30, Is not different from the form support structure (10) about the pillar (30). It is therefore intended that such modifications are within the scope of the invention as set forth in the claims.
