The present invention relates to a mounting base for fixing a hollow foam to a T-shaped deck plate for constructing a hollow slab, and more particularly, to a mounting base for fixing a hollow foam such as a branch pipe to an exact position And the like.

The longevity of a building has been affected more by the problem of the uniformity of the space which can not cope with the change of the life pattern according to the flow of the times along with the aging of the interior and exterior materials rather than the structural problem of the frame.

So far, it has been common to reconstruct the entire structure despite the sufficient lifetime of the frame, and this unreasonable reconstruction has caused another problem such as environmental pollution due to waste of resources and mass release of construction waste materials.

In order to solve these problems, recently, the cases of remodeling the buildings are increasing. Various efforts are being made to increase the lifespan of the buildings such as the policy support of the national government. It is to span the space so that space can be changed into various forms.

 That is, the space having the long span can be variously configured as a non-bearing wall such as a partition, so that it can cope with a change in the life pattern.

A variety of methods for long spaning of buildings have been studied. Among them, a method of increasing the rigidity while lightening the slabs has attracted considerable attention. For example, there is a hollow slab structure shown in FIG.

In the hollow slab, a hollow is formed at the central portion of the end face of the slab by using a light-weight molded body in the T-shaped deck plate so that the I-shaped cross-section has a continuous shape so that the flexural rigidity is increased but the weight is greatly reduced.

More specifically, FIG. 1 is a lightweight molding material assembly for fixedly mounting on a T-shaped deck plate and a lightweight slab structure using the same, which is disclosed in Registration No. 10-1176551 published on July 23, 2012 A plurality of T-shaped decks D are formed by fixing a plurality of T-shaped ribs D1 separated by a vertical portion D11 and a horizontal portion D12 to a T-shaped deck plate D protruding upward in a plurality of rows. (10) having a wide upper body (11) and a lower body (12), the body (10) being divided into two parts by forming a cut surface (14) A narrow support base 12 extending integrally from a lower portion of the upper main body 11, a fixing groove 13 formed on a bonding surface between the upper main body 11 and the support base 12, (15) formed on the cut surface (14), and two The horizontal portion D12 of the T-shaped rib D1 of the T-shaped deck plate D is inserted into the fixing groove 13 while the main body 10 is arranged facing the concave / .

The lightweight slab structure according to the prior art has a beneficial effect in that the lightweight molding material can be easily assembled to the T-shaped deck plate while reducing the number of parts. However, since the horizontal portion of the T- Since the fixing grooves 13 of the lightweight molding material into which the protrusions D12 are inserted are formed only on the joining surfaces of the upper main body 11 and the support base 12, This is because it is difficult to secure a space with respect to the lower end of the slab cross section, which makes it difficult to reinforce the bending stress caused by the reinforced concrete.

In addition, in the state where the two main bodies 10 are engaged only by the uneven portions 15, it can be easily separated by carelessness of the operator or by the concrete insertion pressure, so that there is a troublesome operation to install the anchor 30 , There is a problem in that the material and the shape of the lightweight molding material are limited.

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.

FIG. 2 is a perspective view showing a state where a mounting base according to an embodiment of the present invention is installed on a deck plate, FIG. 3 is a perspective view showing a hollow foam mounting structure of the present invention in which a hollow foam is fixed to the mounting base, Is a perspective view showing the whole mounting structure of an embodiment in which the hollow foam is fixed to a deck plate for fixing the hollow foam.

The hollow foam mounting structure of the deck plate of the present invention for constructing a hollow slab having a hollow portion inside a cross section includes a deck plate 100 forming a lower surface of the slab as shown in FIG. 3, And a mounting table 200 for fixing the hollow foam 300 to the deck plate 100. As shown in FIG.

The deck plate 100 can improve the workability by omitting the work of installing and disassembling the formwork, and can be used not only as a function of a conventional deck plate designed as a structural member, but also as a deck plate, And serves as a means of a fixing bracket that allows the mounting table 200 to be fixed simply.

The deck plate 100 according to the present invention includes a lower plate 110 which functions as a mold and copes with deflection acting on the slab if necessary, and a lower plate 110 which protrudes upward from the lower plate 110, A rib 120 which reinforces the flexural strength of the deck plate 100 and the slab concrete C is formed at the upper end of the rib 120 so as to have a T shape together with the rib 120, A T-shaped deck plate composed of an upper flange 130 which is tightly pressed so as to be able to be fixed to the deck plate 100 is used.

The mounting base 200 of the present invention for fixing the hollow foam 300 to the deck plate 100 in a fixed position is fixed to the deck plate 100 by the elastic force of the upper flange 130, The lower flange 130 and the upper flange 130 of the deck plate 100 while being pressed against each other by the elastic force of the upper flange 130.

As shown in FIG. 4, the mounting table 200 includes a plurality of support angles 210 formed vertically and a horizontal table 220 horizontally formed at an upper end of the support angle 210.

The support angle 210 is formed in such a manner that the lower end thereof abuts on the lower plate 110 of the deck plate 100 and supports the hollow foam 300 from the deck plate 100 while supporting a pressing force by the elastic force of the upper flange 130, And the reinforcing rods of the reinforcing bars 500 and the casting space of the concrete C are formed in the lower portion.

The horizontal bar 220 positioned at the upper end of the support angle 210 provides a means for fixing the hollow foam 300 and directly receiving the elastic force of the upper flange 130, And is fixed to the deck plate 100 together with the angle 210 so that the hollow foam 300 can be accurately positioned at a planned place.

The horizontal base 220 for the deck plate 100 includes a mounting surface 221 at a central portion where the hollow foam 300 is positioned and a lower surface 220 disposed at both ends of the mounting surface 221, And a fitting pressure receiving surface 222 for receiving the pressing force of the upper flange 130.

5 illustrates a process of fixing the mounting table 200 configured as described above to the deck plate 100. As shown in FIG.

The mounting table 200 of the present invention including the supporting angle 210 and the horizontal table 220 can be easily inserted between the lower plate 110 of the deck plate 100 and the upper flange 130 by the operator Even non-skilled workers can work easily.

5, the worker mounts the mounting table 200 on two adjacent upper flanges (not shown) with the lower end of the supporting angle 210 being in close contact with the lower plate 110 of the deck plate 100 (Refer to FIG. 5 (b)) while being rotated (see FIG. 5 (a)) by inserting the upper flange 130 in the longitudinal direction of the rib 120 (See Fig. 5 (c)), the fixed installation work of the mounting table 200 with respect to the deck plate 100 is simply completed.

The configuration in which the mounting table 200 is fixed in the state of being fitted to the lower surface of the upper flange 130 is the same as the configuration of the hollow foam 300 placed on the mounting table 200 using fixing means such as a band 400, This makes it possible to completely block the floatation of concrete by buoyancy.

The upper flange 130 may press the fitting pressure receiving surface 222 of the mounting table 200 or at least the fitting hydraulic pressure surface 222 may be positioned on the upper side of the upper flange 130, It is preferable to prevent the mounting table 200 from being easily moved or rotated by the concrete C poured during the process of inadvertent impact of the operator or pouring of the concrete C by being in close contact with the lower surface of the flange 130.

The distance h1 from the lower end of the support angle 210 to the upper surface of the horizontal support 220 and more specifically from the lower end of the support angle 210 to the upper surface of the engagement pressure receiving surface 222, Is equal to or larger than the distance (h2) from the upper surface of the lower plate (110) to the lower surface of the upper flange (130).

However, even if the distance h1 from the lower end of the support angle 210 to the upper surface of the horizontal table 220 is larger than the distance h2 between the lower plate 110 of the deck plate and the upper flange 130, The upper flange 130 should not be plastically deformed during the installation process of the upper flange 130.

The horizontal strip 220 is preferably configured so that the diagonal length d1 on the plane is equal to or smaller than the shortest length d2 between the inner surfaces of the adjacent ribs 120 of the deck plate 100. [

When the diagonal length d1 of the horizontal base 220 is larger than the shortest length d2 between the inner surfaces of the adjacent ribs 120, The hollow foam 300 may be installed incorrectly or unstably.

Therefore, in the present invention, the diagonal length d1 of the horizontal bar 220 is set to be smaller than or at least equal to the shortest length d2 between the inner surfaces of the ribs 120 of the deck plate 100. [

However, even if the diagonal length d1 of the horizontal bands 220 is shorter than the shortest length d2 between the inner surfaces of the ribs 120, the horizontal length l1 of the horizontal bands 220 is equal to the length of the upper flanges 130 ) Should be longer than the shortest length (l2) between each end.

Since the mounting table 200 is fixed to the deck plate 100 by being rotated between the lower plate 110 and the upper flange 130 of the deck plate 100, The base 220 may further include a rotation guide means.

6 is a perspective view of a mounting table 200 showing an embodiment of the present invention including the rotation guide means.

The rotation guide means is formed by slanting a surface 222a at both ends of the horizontal table 220. More specifically, the surface of the horizontal table 220 is symmetrical with respect to one of the edges of the horizontal table 220, And a downward sloping surface 222a is formed on a pair of corners which are formed by the above-described method.

At this time, the outermost end of the inclined surface 222a is located below the lower surface of the upper flange 130 when the mounting table 200 is placed on the lower plate 110 of the deck plate 100, When the mounting table 200 is rotated as described above, it is preferable that the clamping pressure receiving surface is brought into contact with the lower surface of the upper flange 130 so that an elastic force is generated in the upper flange 130.

When the mounting table 200 is fixed to the deck plate 100, the hollow form 300 is placed and fixed to the mounting surface 221 of the horizontal table 220. At this time, a mounting groove 221a may be further provided at the center of the mounting surface 221 so that the hollow foam 300 may be placed in the correct position of the horizontal table 220.

The fixing groove 221a not only facilitates a fixing work such as a banding for fixing the hollow foam 300 to the horizontal stand 220 but also facilitates fixing the hollow foam 300 to the horizontal stand 220 Thereby preventing movement.

The horizontal base 220 may further include fixing protrusions 223 on both end sides of the mounting surface 221 in addition to the mounting groove 221a. The fixing protrusion 223 facilitates installation of fixing means such as a band 400 for fixing the hollow foam 300 to the horizontal base 220.

The hollow foam 300, which is integrally fixed to the mounting base 200 through the fixing means, is lightweight and may be any shape as long as the shape thereof is not easily deformed by the concrete C. Preferably, It is preferable to use a paper tube.

In addition, the hollow foam 300 may have the same shape, but may have a variable shape depending on its position, so that the hollow foam 300 may have a cross-sectional shape corresponding to a stress acting on the slab. Unlike the prior art shown in FIG. 1, the hollow shape of the cross section can be easily realized by fixing and fixing the hollow foam 300 via the mounting table 200.

The supporting angle 210 of the mounting table 200 can be used to place the reinforcing bars 500 and the concrete C between the lower plate 110 of the deck plate 100 and the hollow foam 300 To form a space.

Therefore, the supporting angle 210 may further include a reinforcing bar 211 for facilitating the work of reinforcing bars 500.

8 and 9 show a mounting table 200 of each embodiment in which the reinforcing bars 211 are installed.

The reinforcing bars 211 may be connected to the supporting angles 210 and the supporting angles 210 as shown in FIG. 8. At this time, the reinforcing bars 211 may be formed as shown in FIG. 8 (a) The support angle 210 may be formed integrally with the support angle 210 from the manufacturing stage and the support angle 210 may be formed in the support angle 210 as shown in FIG. So that the reinforcing bars 211 can be detached and attached to the supporting angles 210 as needed.

The reinforcing bars 211 may be formed so as to protrude from the supporting angle 210 located at the outermost periphery toward the ribs 120 of the deck plate 100 as shown in FIG. 9 (a).

The structure of the reinforcing bars 211 protruding from the supporting angle 210 toward the rib 120 of the deck plate 100 is such that the reinforcing bars 500 to be routed as shown in Figure 9 (b) The reinforcing bars 500 can be placed in advance on the upper surface of the lower plate 110 of the deck plate 100 prior to the fixing operation of the mounting table 200,

The reinforcing bars 211a may be further provided with the reinforcing bars 211a. The reinforcing bars 212a allow the operator to visually recognize the position where the reinforcing bars are to be laid so that the precise laying work can be performed more easily .

10 is a cross-sectional view showing a state in which the reinforcing bars 500 are disposed under the hollow foam 300 and the lower end of the end face of the slab is reinforced. As described above, according to the present invention, reinforcement reinforcement of the hollow slab to the lower portion of the hollow foam 300 can be more easily performed, thereby minimizing the thickness of the slab cross-section, thereby making it possible to construct a hollow slab having an efficient 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. It is therefore intended that such modifications are within the scope of the invention as set forth in the claims.
