Description

Spacer device for securing spacing between pipes of concrete slab layer and construction method of floor structure applying the same}

The present invention relates to members/equipment applied to buildings and methods related thereto, and more specifically, to mechanisms/devices applied to building floor structures and construction methods related thereto.

Noise and vibration transmitted from the upper floor to the lower floor in apartment structures such as buildings or apartments have been raised as a socially important problem, and the biggest problem among these is that the shock to the floor plate of the upper floor is transmitted through the ceiling of the lower floor. It can be said to be an impact sound. Floor impact sounds can be divided into light impact sounds generated by relatively light and hard impacts, and heavy impact sounds generated by relatively heavy and soft impacts. In other words, it can be divided into a light impact sound made up of high-frequency sounds caused by the falling of a small object, and a heavy impact sound made up of low-frequency sounds caused by the falling of a heavy object, an adult walking, or a child running. You can.

As a measure to reduce inter-floor noise, recently buildings or apartments are installing sound-absorbing or cushioning materials on the concrete slab layer to attenuate impact noise during the construction process. However, there are limitations and difficulties in reducing noise from various types of impact sounds using only existing sound-absorbing materials and cushioning materials.

There may be a variety of factors that increase inter-floor noise in buildings, and among them may include non-uniformity of concrete thickness and cross-sectional loss in the concrete slab layer. Multiple pipes may be buried within the concrete slab layer for purposes such as electricity, communication, water supply, and domestic hot water. As pipes buried within the concrete slab layer are located in the shortest distance between rooms before concrete pouring, areas where multiple pipes overlap on the same vertical line occur. In areas where multiple pipes overlap on the same vertical line, the amount of concrete thickness may be less than in other areas, and sound insulation performance may deteriorate in these areas, as well as structural rigidity.

Figure 1 is a photographic image illustrating the installation of a plurality of pipes to be buried in the concrete slab layer during construction of the existing concrete slab layer. The pipes are for purposes such as electricity, communication, water supply, and hot water supply, and may be flexible pipes. Figure 2 exemplarily shows a portion where triple overlap occurs among a plurality of pipes buried in the existing concrete slab layer, and shows a cross section taken along line A-A' in Figure 1. In the area where the triple overlap chip occurs, the concrete cross-sectional loss (loss in the vertical unit plane) may be approximately 21 to 30%, which causes problems such as deterioration of sound insulation performance and deterioration of the rigidity of the structure.

The technical problem to be achieved by the present invention is to secure the horizontal spacing of a plurality of pipes installed in the concrete slab layer in the construction of a concrete slab layer, thereby minimizing the overlap of the plurality of pipes and ensuring uniformity of the amount of concrete. The aim is to provide a spacer device that can improve performance and suppress cross-sectional loss, reduce inter-floor noise, and improve the rigidity of the structure.

In addition, the technical problem to be achieved by the present invention is to provide a method of constructing a building floor structure using the above-described spacer device.

A plurality of separation areas are defined between and around them, at least some of the plurality of pipes are inserted into at least some of the plurality of separation areas, and at least two of the plurality of pipes are defined by the plurality of second members. A spacer device for securing a gap between pipes in a concrete slab layer, which secures a gap in the horizontal direction, is provided.

The first member may be an upper plate portion, and the plurality of second members may be downwardly extending portions extending downward from the lower surface of the upper plate portion.

When one of the two second members is called a 2-1 member and the other is called a 2-2 member, the gap between the 2-1 member and the 2-2 member is the 2-1 member. It may be shorter than the gap between a member and one end of the first member adjacent thereto and the gap between the second-second member and the other end of the first member adjacent thereto.

The plurality of second members may have a cylindrical, square, or triangular pillar shape.

The first member may include at least one through hole formed in the thickness direction, and the concrete of the concrete slab layer may be inserted into the at least one through hole.

At least a portion of the first and second members may be made of plastic.

At least a portion of the first and second members may be made of metal.

The spacer device may have a fastening member-free configuration that does not require a separate fastening member for fastening to the pipe.

According to other embodiments of the present invention, using the above-described spacer device, widening the horizontal distance between at least two of the plurality of pipes installed on the foundation surface for concrete slab layer construction; and pouring concrete on the foundation surface to form a concrete slab layer. A construction method of a building floor structure is provided, including a step.

The step of widening the horizontal distance between at least two of the plurality of pipes using the spacer device includes moving the spacer device laterally with respect to the pipes to separate the plurality of pipes defined by the plurality of second members.

According to embodiments of the present invention, during the construction of a concrete slab layer, the horizontal spacing of a plurality of pipes installed in the concrete slab layer is easily secured, thereby minimizing the vertical overlap of the plurality of pipes. A spacer device that can be implemented can be implemented. By using the spacer device according to the embodiments, the amount of concrete filling and its uniformity within the concrete slab layer can be improved and cross-sectional loss can be suppressed. As a result, inter-floor noise is reduced and the rigidity of the structure is improved. You can get the effect.

In addition, the spacer device according to embodiments of the present invention may have a relatively simple structure and may not require a separate fastening process using bolts or nuts, so there is an advantage that construction using it is very simple.

Figure 3 is a perspective view showing a spacer device 100 for securing the gap between pipes in a concrete slab layer, according to an embodiment of the present invention.

Referring to FIG. 3, the spacer device 100 for securing the gap between pipes of a concrete slab layer according to an embodiment of the present invention is a spacer device 100 that is installed in a plurality of pipes (not shown) in the concrete slab layer during construction of the concrete slab layer. It is a device (instrument or structure) to widen the gap in the horizontal direction.

The spacer device 100 includes a first member 10 extending in a first direction and a plurality of second members extending from the first surface of the first member 10 in a second direction different from the first direction. (20) may be included. The plurality of second members 20 may be arranged to be spaced apart from each other in the first direction. The first direction may be, for example, the X-axis direction. The first member 10 may have a shape extending in the X-axis direction. The first member 10 may have a ‘length’ in the X-axis direction and a ‘width’ in the Y-axis direction. The length may be greater than the width. Meanwhile, the second direction may be perpendicular to the first direction. For example, the second direction may be the Z-axis direction. The second member 20 may have a shape extending downward from the lower surface of the first member 10 in the drawing. At this time, the second member 20 can be said to have a length along the Z-axis direction. The plurality of second members 20 may be arranged to be spaced apart from each other in the X-axis direction. The first member 10 may be referred to as the 'first part' of the spacer device 100, and the second member 20 may be referred to as the 'second part' of the spacer device 100.

A plurality of separation areas may be defined between and around (on both sides) the plurality of second members 20 . At least some of the plurality of pipes installed in the concrete slab layer may be inserted into at least some of the plurality of separation areas. Accordingly, the distance between at least two of the plurality of pipes in the horizontal direction can be secured by the plurality of second members 20. This will be described in more detail later with reference to FIGS. 6, 7, 9, and 10. Here, the plurality of pipes are buried in the concrete slab layer, and may be pipes for, for example, electricity, communication, water supply, hot water supply, etc. The plurality of pipes may be flexible pipes. For example, the plurality of pipes may be corrugated pipes made of plastic.

According to one embodiment, the first member 10 may have an elongated plate structure. The first member 10 may be an upper plate. The plurality of second members 20 may be downwardly extending portions extending downward from the lower surface of the upper plate portion (i.e., 10). The plurality of second members 20 may be disposed on the central portion of the lower surface of the first member 10 along the Y-axis direction or on a portion adjacent thereto. The plurality of second members 20 may have the shape of, for example, a cylinder, a square pillar, or a triangular pillar. Figure 3 shows a case where the plurality of second members 20 have a cylindrical shape. When the second member 20 has a cylindrical shape, the second member 20 occupies a relatively small volume and can effectively perform the function of separating pipes from each other without disturbing the flatness of the concrete. Additionally, in this regard, dimensions such as width (diameter) and length of the second member 20 may be determined appropriately.

According to one embodiment, two second members 20 may be disposed on the first surface (lower surface in the drawing) of the first member 10 to be spaced apart from each other. When two second members 20 are disposed on the first surface (lower surface in the drawing) of the first member 10, the spacer device 100 can have a relatively simple structure and small size, and installation/construction is easy. It can have the advantage of being easy. However, depending on need, the number of second members 20 may be three or four or more.

When two second members 20 are disposed on the first surface (lower surface in the drawing) of the first member 10, one of the two second members 20 is called a 2-1 member 20a. It can be done, and the other one can be called the 2-2 member 20b. At this time, the gap (minimum gap) d1 between the 2-1 member 20a and the 2-2 member 20b is between the 2-1 member 20a and one end of the adjacent first member 10. may be shorter than the interval (minimum interval) d2 and the interval (minimum interval) d3 between the 2-2 member 20b and the other end of the adjacent first member 10. In other words, d1 may be smaller than d2 and d3, respectively. Additionally, d2 and d3 may be the same or similar. In this case, when spacing a plurality of pipes using the spacer device 100, it may be easier to hold the plurality of pipes more stably with the spacer device 100. However, the length conditions of d1, d2, and d3 are not limited to the above and may vary. In some cases, d1, d2, and d3 may have the same or similar lengths.

According to one embodiment, at least a portion of the first and second members 10 and 20 may be formed of plastic. Both the first and second members 20 may be formed of plastic. The first and second members 20 may have relatively strong strength and some degree of flexibility. When the first and second members 20 are mainly formed of plastic, manufacturing of the spacer device 100 may be easy and manufacturing costs may be lowered. However, the materials of the first and second members 10 and 20 are not limited to plastic and may include other materials. For example, in another embodiment, at least a portion of the first and second members 10 and 20 may be formed of metal. At this time, both the first and second members 20 may be formed of a metal material. When the first and second members 20 are mainly formed of metal, the spacer device 100 may have excellent strength and durability.

According to one embodiment, the spacer device 100 may have a fastening member-free configuration that does not require a separate fastening member for fastening to the pipe. Therefore, a separate fastening process using bolts or nuts, etc. may not be performed to secure the spacer device 100 and the pipe. By using the overall structure and design of the spacer device 100, the repulsive force of flexible pipes is used, a part of the spacer device 100 is placed between the pipe and surrounding structures (reinforcement bars, etc.), or a part of the spacer device 100 is placed between the pipe and the spacer device 100. ), the pipe can be made to hang on the spacer device 100 by placing surrounding structures (rebar, etc.) between parts of the spacer device 100. Therefore, the spacer device 100 can have a relatively simple structure and can have the advantage of being very easy to install/construct. After construction of the spacer device 100, concrete is poured so that internal structures (e.g., pipes, spacer devices, reinforcing bars) can be firmly fixed by the cohesive force of the concrete. However, if necessary, it is possible to separately provide the spacer device 100 with a predetermined fastening member (fastening structure) for coupling/fastening to the pipe.

Figure 4 is a perspective view illustrating the dimensions that each part of the spacer device 100 according to an embodiment of the present invention may have.

Referring to FIG. 4, the gap (minimum gap) d1 between the 2-1 member 20a and the 2-2 member 20b is the distance between the 2-1 member 20a and the first member 10 adjacent thereto. ) may be shorter than the interval (minimum interval) (d2) between one end of the 2-2 member (20b) and the other end of the first member (10) adjacent thereto (minimum interval) (d3). In other words, d1 may be smaller than d2 and d3, respectively. Additionally, d2 and d3 may be the same or similar. Additionally, the length of the first member 10 in the X-axis direction may be relatively larger than the length of the second member 20 in the Z-axis direction. Meanwhile, as a non-limiting example, each pipe (not shown) subject to spacing may have a diameter of about 28 mm. The dimensions of each part of the spacer device 100 shown in FIG. 4 are merely examples and may vary depending on the case.

Figure 5 is a perspective view showing a spacer device 110 for securing the gap between pipes in a concrete slab layer according to another embodiment of the present invention.

Referring to FIG. 5, the spacer device 110 according to the present embodiment includes a first member 10 extending in a first direction and a first surface (e.g., lower surface in the drawing) of the first member 10. may include a plurality of second members 21 extending in a second direction different from the first direction. The plurality of second members 21 may have a square pillar shape. When two second members 21 are disposed on the first surface (e.g., lower surface in the drawing) of the first member 10, one of the two second members 21 is called the 2-1 member 21a. ) and the other one can be called the 2-2 member (21b). In the spacer device 110 of FIG. 5 , the remaining configuration except for the shape of the second member 21 may be the same or similar to the spacer device 100 described in FIG. 3 .

FIG. 6 is a diagram illustrating a method of securing horizontal spacing between a plurality of pipes 50 installed on a concrete slab layer using a spacer device 100 according to an embodiment of the present invention.

The left drawing of FIG. 6 corresponds to a case in which the spacer device 100 is not used, and shows a case in which a concrete slab layer 1000 is formed with a plurality of pipes 50 arranged to overlap in the vertical direction. In this case, the three pipes 50 may be arranged to overlap in the vertical direction.

The drawing on the right side of FIG. 6 corresponds to the case where the spacer device 100 is used. In the spacer device 100, a plurality of separation areas may be defined between and around (on both sides) the plurality of second members 20. At least some of the plurality of pipes 50 installed in the concrete slab layer may be inserted into at least some of the plurality of separation areas. For example, at least two pipes 50 may be respectively inserted into at least two separate regions. Accordingly, the horizontal distance between at least two of the plurality of pipes 50 can be secured by the plurality of second members 20 . Through this, the overlap of the pipes 50 in the vertical direction can be minimized. For example, the overlap of the three pipes 50 can be made to be two or less overlaps, and the maximum number of overlaps can be made to be two or less. Reference number 70 represents reinforcing bars installed around the spacer device 100. The positions of the reinforcing bars 70 are exemplary and may vary. Using the repulsive force of the flexible pipes 50, placing a part of the spacer device 100 between the pipe 50 and the reinforcing bar 70, or between the pipe 50 and a part of the spacer device 100 By arranging the reinforcing bar 70, the pipe 50 can be made to hang on the spacer device 100 even without a separate fastening member.

After construction of the spacer device 100, concrete can be poured to form a concrete slab layer, and internal structures (e.g., pipes, spacer devices, reinforcing bars) can be firmly fixed by the cohesion of the concrete.

Figure 7 illustrates a case in which the horizontal spacing between a plurality of pipes 50 is secured using the spacer device 100 according to an embodiment of the present invention, and then concrete is poured to form a concrete slab layer 1100. It is a cross-sectional view showing it overall and partially.

Referring to FIG. 7, by using the spacer device 100 according to an embodiment of the present invention, it is possible to secure a gap in the horizontal direction of at least two of the plurality of pipes 50, and the vertical direction of the pipes 50 Overlap can be minimized. For example, the overlap of the three pipes 50 can be made to be two or less overlaps, and the maximum number of overlaps can be made to be two or less.

In the case of Figure 2 described above, the concrete cross-sectional loss (loss in the vertical unit plane) may occur by approximately 21 to 30% in the area where the triple chip of the pipe occurs, resulting in a decrease in sound insulation performance and a decrease in the rigidity of the structure. Problems arise.

However, according to an embodiment of the present invention, as shown in FIG. 7, the vertical overlap of the pipes 50 can be minimized, and the cross-sectional loss is about 20% or less (for example, about 14 It can be reduced to about ∼20%). Therefore, by using the spacer device according to the embodiments, the amount of concrete filling and its uniformity within the concrete slab layer can be improved, and as a result, the effect of reducing inter-floor noise and improving the rigidity of the structure can be obtained. .

Figure 8 is a perspective view showing a spacer device 120 for securing the gap between pipes in a concrete slab layer according to another embodiment of the present invention.

Referring to FIG. 8, the spacer device 120 according to the present embodiment includes a first member 11 extending in a first direction and a first surface (e.g., lower surface in the drawing) of the first member 11. may include a plurality of second members 20 extending in a second direction different from the first direction. Here, the first member 11 may include at least one through hole H1 formed in its thickness direction. For example, a plurality of through holes H1 spaced apart from each other may be formed in the first member 11 . When viewed from above, each second member 20 may be disposed between two through holes H1. In the spacer device 120 of FIG. 8 , the remaining configuration, except that the through hole H1 is formed in the first member 11, may be the same or similar to the spacer device 100 described in FIG. 3 .

In the structure of FIG. 8, the concrete of the concrete slab layer may be inserted into the through hole H1. Therefore, since the concrete is connected in the vertical direction through the through hole H1, the bonding area of the concrete increases and the amount of sanding increases, thereby improving the cohesion and adhesion strength. The number, size, and arrangement of the through holes H1 shown in FIG. 8 are exemplary and may vary depending on the case.

The construction method of a building floor structure according to an embodiment of the present invention includes the steps of using the above-described spacer device to widen the horizontal gap between at least two of a plurality of pipes installed on the foundation surface for constructing a concrete slab layer; It may include forming a concrete slab layer by pouring concrete on the foundation surface. The step of widening the horizontal distance between at least two of the plurality of pipes using the spacer device is to move the spacer device laterally with respect to the pipes to separate the plurality of pipes defined by the plurality of second members. It may include inserting at least some of the plurality of pipes into at least a portion of the area and rotating the spacer device. Once the concrete slab layer is formed, a buffer layer, a lightweight cellular concrete layer, and a finishing mortar layer can be further sequentially formed thereon. In some cases, a sound-absorbing material layer (sound-insulating material layer) may be further formed between the cushioning material layer and the lightweight foam concrete layer.

Then, the spacer device 100 can be rotated so that the first member 10 is disposed upward. Through this, the plurality of pipes 50 that initially overlapped in the vertical direction can be spaced apart in the horizontal direction. The positions of the spacer device 100 and the pipes 50 can be fixed using the repulsive force of the plurality of pipes 50 or the reinforcing bars 70 installed around the spacer device 100.

In Figure 9, one of the plurality of pipes 50 is disposed between the 2-1 member 20a and the 2-2 member 20b, and the other is disposed outside the 2-1 member 20a. Although the case has been described, the construction method of the spacer device 100 may vary in various ways.

A spacer device that can minimize overlap can be implemented. By using the spacer device according to the embodiments, the amount of concrete filling and its uniformity within the concrete slab layer can be improved and cross-sectional loss can be suppressed. As a result, inter-floor noise is reduced and the rigidity of the structure is improved. You can get the effect.
