Description

  The present invention belongs to a technical field of providing a ventilation function to a one-way void slab employed in a slab of a building, and a slab exhaust structure and a slab supply structure using a one-way void slab having a ventilation function.

Since the void slab is a slab frame that does not require a small beam, it is widely used in recent slab construction methods. In addition, in order to improve the view by attaching a large sash, the structure is such that a large beam on the balcony or shared corridor side is put out on the outside of the balcony or shared corridor, or a flat beam with a beam equivalent to the thickness of the void slab is used. It has been developed and various ideas have been made to provide a comfortable living space. When a void slab is used in such a frame, it is common to pass the void between the earthquake resistant walls near the center of the slab, and pass the void between the previous void and the large beam near the balcony or the common corridor. . This method is called a two-way void slab slab.In this case, since a small void opening is arranged toward the balcony or the common corridor, and a ventilation facility such as a duct can be substituted with the void slab void, the following solution of the present invention There are no issues.
On the other hand, recently, in order to improve not only the living space but also the productivity at the time of construction, a frame structure different from a wall type structure that does not require a beam or a column itself has been implemented. Although the structure is composed only of a shear wall and a void slab, all voids of the void slab are passed between the shear walls in such a frame. This method is called a one-way void slab.
In the case of a one-way void slab, there is no void toward the balcony or the common corridor, so ventilation equipment such as ducts cannot be substituted with void slab voids. Therefore, in spite of the absence of pillars and beams, it is necessary to take measures to lower the beam shape and ceiling for covering the ventilation equipment in whole or in part so that the ventilation equipment can be accommodated, or to expose the ventilation equipment. There was a problem that the living performance secured by the housing was ruined by the ventilation equipment.

Conventionally, the idea of utilizing voids of a void slab for a ventilation facility function has already been proposed and known as several inventions.
For example, the invention “void slab having equipment function” disclosed in the following Patent Document 1 is based on the idea of using each hollow part of the void slab as an air conditioner, a ventilation duct, an electric pipe, or a wiring space. A structure is provided in which a through-hole is formed toward the lower surface or the upper surface of the slab, and this through-hole is used as an air outlet or a suction port. However, nothing is disclosed about the examination or solution when the above-described void formation direction and the ventilation duct installation direction are different.
The invention disclosed in Patent Document 2 “High-rise buildings with atriums” is formed by forming the floor of each residential layer of a high-rise building with a void slab, and ventilating the hollow portion from the balcony side to the inner corridor side. Provides a configuration that ensures ventilation performance. Therefore, it is a precondition that the hollow part of the void slab is formed in the long side direction, that is, in the direction orthogonal to the frontage direction of the building.

The invention “ventilation duct system” disclosed in Patent Document 3 is configured so that an exhaust intake port formed in a ceiling slab, a hollow duct formed from there to a balcony slab, and the hollow duct communicated with a lower surface of the balcony slab. The structure provided with the exhaust port formed in FIG. However, the ceiling slab has a structure including the “beam 14 facing outside” at the boundary portion with the balcony slab, and cannot be said to be a flat slab structure type.
The invention “thermal storage air conditioning system using void slab” disclosed in Patent Document 4 is configured such that each void of the void slab is partitioned in the longitudinal direction by a plate material and communicated at one end, and further connected to an air conditioner. The configuration used for switching is shown in FIG. Therefore, nothing is disclosed about the examination or solution when the void direction in the void slab is different from the installation direction of the ventilation duct.

The invention “Void Slab Utilizing Air Conditioning System” disclosed in Patent Document 5 below proposes an air conditioning system that uses a void slab as a duct communicating with a room in a building that employs a void slab. A blowout port is provided as a blowout duct, and the other ducts have a configuration in which an air suction port is provided as an air suction duct in a lower floor room.
Therefore, nothing is disclosed or even a problem regarding the examination and solution when the void formation direction in the void slab is different from the installation direction of the ventilation duct.

JP-A-6-313342 Japanese Patent Laid-Open No. 6-299710 Japanese Patent Laid-Open No. 10-122625 Japanese Patent Laid-Open No. 10-220813 JP-A-2-251027

  As often described above, several proposals have been made regarding buildings that employ void slabs or ventilation duct systems that use voids of void slabs. However, as the structure of the void slab, it is a building of the structure type that cannot adopt the two-way void slab, and under the conditions other than adopting the one-way void slab, as described above, it was directed to the balcony side or the common corridor. Because there are no voids, ducts and other ventilation equipment cannot be substituted with void slab voids.

Therefore, generally, as illustrated in FIG. 11A, a ventilation duct d is disposed under the ceiling of the one-way void slab b, and the outer end of the duct is, for example, on the balcony side window as illustrated in FIG. 11B. The work which attaches and supports the beam type e or the ceiling board f which conceals the beam type e or the ventilation duct d toward the window surface from the room like FIG. 11C is performed. As a result, the view from the outside through the window on the balcony is obstructed. Moreover, if the ceiling board f is attached as shown in FIGS. 11A and 11C, the effective ceiling height is lowered, which causes a serious problem that the view is hindered and the feeling of opening is impaired.
However, there is no conventional technology that focuses on the above-mentioned problems and proposes solutions.
Of course, in order to arrange the ventilation duct under the ceiling, it is inevitable that the duct installation work and construction costs for that purpose will be generated and become expensive.

The next object of the present invention is to eliminate the necessity of installing a ventilation duct on the lower surface of the slab (or the lower surface of the ceiling) by adopting the unidirectional void slab having the above ventilation function in a flat slab structure building. The installation work and its construction costs are made useless, and there is no need to form a beam type that covers the ventilation duct or to install a ceiling plate, so that the effective height of the ceiling surface can be made flat and the balcony side window surface can be formed. The object is to provide a slab exhaust structure or a slab air supply structure that can be designed and constructed with a full sash with a wide view and visibility, and that exhibits the original features of a flat slab structure building.
A further object of the present invention is to eliminate the need to remove or newly install ventilation ducts during renovation (repair or renovation), and to eliminate the construction costs, and to select the connection position of ventilation devices relatively freely.

In addition, according to the above-described slab exhaust structure or slab air supply structure of the present invention, the work for removing or newly installing the ventilation duct and the construction cost at the time of renovation and the like are unnecessary, and the connection position of the ventilation ducts is determined. You can choose relatively freely. Further, when changing the layout of the ventilation system after occupying the building, for example, the position of the ventilation short pipe 4 is selected, and the route of the ventilation airflow can be changed freely by operating the on-off valve 5 accordingly. There is convenience.

A ventilation void tube 3 communicating with the void 2 is disposed in a one-way void slab 1 in which a plurality of voids 2 arranged in parallel are formed. The ventilation void tube 3 or the void 2 opens at the upper surface or the lower surface of the slab 1. Connect the short pipe 4 for ventilation. Further, an open / close valve 5 for setting the route of the air flow for ventilation is installed in the void tube 3 and the void 2 to constitute the one-way void slab 1 having a ventilation function.
The one-way void slab 1 having the ventilation function is implemented as a cast-in-place concrete slab or a precast concrete slab.
The exhaust gallery 6 or the exhaust device 60 is attached to the end of the void tube 3 for ventilation of the void slab 1 in the building constructed using the one-way void slab 1 having the ventilation function.

And ventilation equipment is attached to the short pipe 4 for ventilation of the important point, and the lid | cover 8 is attached to the other short pipe 4 for ventilation, and it closes. Furthermore, the slab exhaust structure or the slab air supply structure is configured by adjusting each on-off valve 5 so as to generate an exhaust flow or a supply air flow in the room through the ventilation equipment to form an exhaust or supply route.

Next, the present invention will be described based on the illustrated embodiment.
First, FIG. 1 and FIG. 2 show the Example of the standard structure of the one way void slab 1 which has the ventilation function based on this invention.
In the case of the present embodiment, a plurality of voids 2 parallel to the short side direction of the slab are formed, and the long side direction of the one-way void slab 1 intersects and communicates with the void 2 in the short side direction. A void tube 3 is arranged. Further, a ventilation short tube 4 that opens toward the lower surface (or the upper surface; the same shall apply hereinafter) of the slab is connected to the required points of the ventilation void tube 3 and the voids 2 arranged in parallel in the short side direction. In addition, a plurality of on-off valves 5 for setting the route of the air flow for ventilation are installed at the necessary places of the void tube 3 for ventilation and the void 2 parallel to the short side direction. That is, in this one-way void slab 1, as an example, a pipe system as shown in FIG. 3 is integrally embedded in the slab concrete. Incidentally, reference numeral 2a in FIG. 3 is a pipe that forms the void 2 parallel to the short side direction, 3a is a pipe that forms the ventilation void tube 3, and 4a is a pipe that forms the ventilation short tube 4. For example, thin steel pipes or aluminum pipes are used. Reference numeral 8 denotes a lid for closing the opening of the ventilation short pipe 4.
In the case of the illustrated embodiment, the void 2, the ventilation void tube 3, and the ventilation short tube 4 are shown as circular, but this is not restrictive. It is also possible to use a square tube, an elliptical tube, or an oval tube whose corners are R-processed.

More specifically, the configuration of the embodiment of FIG. 1 will be described.
Two ventilation void tubes 3 arranged in the long side direction of the slab are arranged so as to intersect and communicate with the left and right ends of the voids 2 in the short side direction, and also intersect with each of the voids 2 in the center position of the slab. A total of three are installed in a communication configuration.
In FIG. 1, the position of the ventilation short tube 4 that opens on the lower surface of the slab is indicated by a white circle 4 at the intersection point where the long-side ventilation void tube 3 and the short-side direction void 2 intersect. Show. However, if necessary, it can be carried out with a configuration and arrangement connected to the necessary locations of the ventilation void tube 3 and the voids 2.
An example of use of the ventilation short pipe 4 is shown in FIG. As an example, an exhaust louver 6 is attached to the opening of the ventilation short tube 4 connected to the left end position exposed to the outside of the ventilation void tube 3 to form an exhaust opening. Conversely, a ventilation fan duct 7 of a kitchen or a unit bath (UB) is connected to the opening of the ventilation short pipe 4 located on the right side of FIG. Then, a lid 8 is attached to the opening of the short ventilation pipe 4 that is not used at an intermediate position between the two, so that a series of ventilation (exhaust or air supply) routes are set in the left-right direction.
As another embodiment, FIG. 6 shows an example in which the range hood 10 is connected to the ventilation short pipe 4 that opens in the ceiling of the kitchen. FIG. 7 shows an embodiment in which the duct of the bath ventilation fan 11 is connected and exhausted. As shown in FIG. 6 or FIG. 7, the place where the range hood 10 and the ventilation fan 11 for the bath are installed in a suspended state under the ceiling is, for example, adjacent to the partition wall between the rooms, considering the indoor view and appearance. It is desirable that the design and construction be installed at a position as far as possible from the balcony side window surface, such as facing the built-in storage section and being provided integrally with the storage section.
Further, as shown by a dotted line 30 in FIG. 2 or FIG. 8, the ventilation void tube 3 is installed in a configuration that penetrates the slab and opens at the end face of the slab, and makes the ventilation flow (exhaust) in the horizontal direction. It is also preferable to carry out the structure in which the gas is discharged.

Next, in the embodiment of FIG. 1, a representative example of the installation position of the on-off valve 5 for setting the route of the air flow for ventilation is shown with a circle in the circle. In the embodiment of FIG. 1, the on-off valve 5 is shown only for the purpose of closing the airflow flowing through the ventilation void tube 3 and the voids 2. There are also many on-off valves 5 that allow the airflow flowing through the ventilation void tube 3 and the voids 2... To flow in a fully open state, but the illustration of them is merely omitted. In short, it is implemented based on the idea that the required number of airflows for ventilation in the future are installed in the necessary number at the position (appropriate place) that will be necessary.
As a specific configuration of the on-off valve 5, various structures and types of valves can be implemented, and typical examples are shown in FIGS.
The balloon type opening / closing valve 5 in FIG. 5A is inserted into the air flow cavity of the ventilation void tube 3 or the void 2 through the short ventilation tube 4 while the spherical valve body 51 such as a stretchable balloon or a soccer ball is deflated. An air cylinder (not shown) is used, and air is blown and inflated from the vent valve port 50 so as to be strongly pressed against the inner wall surface of the cavity, and the airflow cavity is closed by positioning with the frictional force. The processing for increasing the positioning frictional force is also performed as necessary. On the contrary, the spherical valve body 51 is taken out through the ventilation short pipe 4 by drawing air from the vent valve port 50 and deflating the spherical valve body 51, and the air flow cavity is fully opened.
The screw type on-off valve 5 shown in FIG. 5B has a thread 53 formed in advance on the inner wall of the air flow cavity of the ventilation void tube 3 or the void 2, and has a disk shape with an outer diameter and a thickness that can be screwed into the thread 53. The valve body 52 having a half-folded structure by a 180 degree rotatable hinge is inserted into the air flow cavity of the ventilating void tube 3 or the void 2 through the short ventilating pipe 4 in a folded state, and is formed into a disk shape. The air flow cavity is closed by being screwed into the screw thread 53 on the inner wall of the air flow cavity while rotating using the handle 52a. In this case, the stability of the unfolded state is maintained by setting the side receiving the wind pressure of the airflow as the hinge stop side. When the valve body 52 is no longer needed, the valve body 52 is reversely operated to be removed from the screw thread 53, folded in a folded state, taken out through the ventilation short tube 4, and the airflow cavity is fully opened.
The rotary on-off valve 5 shown in FIG. 5C has a valve body 54 that rotates horizontally around an upper and lower vertical shaft 55 supported on the inner wall of the air flow cavity of the void tube 3 or 2 for ventilation. It is the structure which installs by the disk structure of the same shape as the cross section of this air flow cavity, positions the valve body 54 in a cross direction, and makes an air flow cavity fully closed. The air flow cavity can be fully opened by rotating the valve body 54 by 90 degrees and positioning it in the direction parallel to the air flow.
The undulating on-off valve 5 shown in FIG. 5D has a disc shape having an outer diameter substantially equal to the inner diameter of the ventilation void tube 3 or the void 2, and a valve body 56 attached to the inner wall of the airflow cavity by a hinge 57 so as to be able to undulate. It is the structure which closes the air flow cavity of the void tube 3 for ventilation, or the void 2 by standing and positioning to the attitude | position to cross. On the contrary, the air flow cavity can be fully opened by using the handle 59 and horizontally positioning the valve body 56 with the stopper 58 as shown by the dotted line.

The unidirectional void slab 1 having a ventilation function according to the present invention can be implemented in any configuration as a cast-in-place concrete slab or a precast concrete slab. Regardless of the configuration, a method of manufacturing the one-way void slab 1 having the ventilation function is preferably a method in which a pipe system as illustrated in FIG. 3 is manufactured in advance and is driven into concrete. To be implemented. In FIG. 3, reference numeral 2a is a pipe that forms a void 2 parallel to the short side of the slab, 3a is a pipe that forms a ventilation void tube 3, reference numeral 4a is a ventilation short pipe tube, and 8 is a ventilation short pipe. A lid for closing the tube 4 is shown.
Incidentally, as illustrated in FIG. 4, the pipe system having the above-described configuration is disposed in the slab form together with the slab rebars 12, and concrete is placed and cured to produce the unidirectional void slab 1 having a ventilation function. The

Next, FIG. 8 shows that the unidirectional void slab 1 having the ventilation function configured as described above is employed in a slab of a flat slab structure building, an exhaust route is formed in the upper slab, and the lower unidirectional void slab 1 is supplied to the slab. 1 schematically illustrates an embodiment of an indoor ventilation system that forms an air route. The code | symbol 21 in a figure shows the sliding door of the balcony side window surface, and 22 has shown the outer wall of the common corridor side.
In the upper unidirectional void slab 1, an exhaust device 60 is connected downward to a ventilation short tube 4 positioned at the left end (outer end) of a ventilation void tube 3 used for exhaust, and the ventilation void tube 3. An exhaust flow route is formed by using a ventilation short pipe 4 connected to an exhaust system centering on the top and opening to the ceiling surface as an exhaust port.
The ventilation void tube 3 in the lower one-way void slab 1 is used for supplying air. An air supply duct 70 is connected to the ventilation short tube 4 at the right end of the ventilation void tube 3 and is connected to an air supply system centered on the ventilation void tube 3 to open to the floor surface. 4 is used as an air supply port, and the air supply route of FIG. 8 is formed.
Note that the ventilation void tube 3 in the unidirectional void slab 1 in FIG. 8 is configured to penetrate horizontally to the left end of the slab 1 as illustrated by the dotted line 30, and the exhaust gas is horizontally installed without attaching the exhaust device 60. As already described, it can be implemented with a configuration that flows to the left in the direction.

Further, an embodiment of setting an exhaust route and an air supply route for the one-way void slab 1 having a ventilation function according to the present invention will be described first based on a plan view of FIG.
In the case of the unidirectional void slab 1 shown in FIG. 1, two void tubes 3 and 3 for ventilation arranged vertically at both ends of the voids 2 parallel to the short side direction of the slab communicate with the voids 2. Has been. In addition, one ventilation void tube 3 is vertically arranged at the center of the voids 2 parallel to each other in the short side direction. As an embodiment of the exhaust system in the one-way void slab 1 having the above-described configuration, reference symbols (i), (b), and (c) denote ventilation (exhaust) equipment such as the range hood 10 shown in FIG. 6 or the bath ventilation fan 11 shown in FIG. The position where the apparatus is connected to the short pipe 4 for ventilation is shown. Moreover, the code | symbol D has pointed out the exhaust open place (short pipe 4 for ventilation) which attached the gallery 6 shown, for example in FIG. Thus, (i), (b), (c), and (d) show examples of a kind of collective exhaust route.
1 represents the connection position of the ventilation equipment, and the symbol F represents the exhaust opening location. Similarly, the symbol “G” in FIG. 1 indicates the connection position of the ventilation equipment, and the symbol “H” indicates the exhaust opening location. In any case, the connection state (exhaust route) relating to the void 2 parallel to the short side direction of the unidirectional void slab 1, the vertical ventilation void tube 3 communicating with the void 2, and the position of the short ventilation tube 4 connected thereto. Are effectively combined.

Next, FIGS. 9A and 9B also show an example in which an exhaust route and an air supply route are set for the one-way void slab 1 having the ventilation function of the present invention as a plan layout view. However, in the unidirectional void slab 1 having the ventilation function shown in FIG. 9A, two ventilation void tubes 3 and 3 are vertically arranged at both ends of the voids 2 parallel to the short side direction of the slab, and One ventilation void tube 3 is also intermittently disposed in the center of the void 2 in the vertical direction. However, the mode in which each of the void tubes for ventilation 3 communicates with the voids 2... Arranged in parallel in the short side direction is configured to be greatly different from that in FIG. The differences will be described below.
First, in the unidirectional void slab 1 having the ventilation function shown in FIG. 9A, the voids 2 parallel to the short side direction of the slab have a total of eight voids 2 counted from the lower side in the long side direction of the slab. It is divided into three groups: “Group I” including “Group II” including only one middle void 2 and “Group III” including eight voids 2 on the upper side. Each of the voids 2 in the “Groups I and III” includes a total of three ventilation voids including two ventilation void tubes 3 disposed at both ends and one ventilation void tube 3 disposed in the center. Each of the void tubes 3 communicates in common. However, one void 2 of “Group II” is not communicated with any ventilation void tube 3.

Since the one-way void slab 1 having a ventilation function shown in FIG. 9A has the above-described configuration, first, as for the configuration of the ventilation route, the symbols a and b belonging to “Group III” are a toilet or kitchen (UB) that emits an odor. The ventilation equipment apparatus connected with the short pipe 4 for ventilation located in the place which excludes the odor of is shown. A symbol C indicates a place where the odor is released. In other words, Route I, B, and Ha form an odor exhaust route based on the independently configured “Group III”.
The other symbols “D” and “H” belonging to “Group I” indicate ventilation equipment connected to the ventilation short pipe 4 located in a place where indoor ventilation is required. Show.
That is, since the two types of exhaust are performed in different systems, the grouping of the voids 2 arranged in parallel in the short side direction of the slab works effectively.

  Next, the unidirectional void slab 1 having the ventilation function shown in FIG. 9B has two ventilation voids in the long side direction (vertically) along both ends of the voids 2 parallel to the short side direction of the slab. Tubes 3 and 3 are arranged. However, unlike the embodiment of FIG. 1, the ventilation void tube is not disposed in the center of the void 2. Then, the ends of the voids 2 parallel to the short side direction are, for example, clear from the variable side in order of the respective voids 2 in FIG. 9B. Although it communicates with and communicates with the void tube 3 for ventilation, the right end does not reach the position of the right void tube and is in a dead end state. Next, when looking at the next higher void 2, the right end intersects and communicates with the right ventilation void tube 3, but the left end of the void 2 reaches the position of the left ventilation void tube 3. First, it is stopped at the front position and is not connected. Further, the same configuration is repeated for each of the upper voids 2, and each of the voids 2 in the short side direction is configured to communicate with the left and right ventilation void tubes 3 and 3 alternately in a zigzag arrangement. .

  Since the one-way void slab 1 having the ventilation function shown in FIG. 9B has the above-described configuration, the configuration of the ventilation route shown in FIG. 9B is the odor of the toilet or kitchen (UB) that emits an odor. The ventilation equipment apparatus connected with the short pipe 4 for ventilation located in the place which excludes is shown. A symbol C indicates a place where the odor is released. On the other hand, the symbols D, E, H, G indicate ventilation equipment connected to the ventilation short pipe 4 located in a place where indoor ventilation is required. The symbol H indicates the exhaust opening location. That is, each of the voids 2 in the short side direction is configured to communicate with the left and right ventilation void tubes 3 and 3 alternately in a zigzag-like arrangement, thereby opening the odor release route and the indoor ventilation route. Are formed efficiently.

In short, the unidirectional void slab 1 having the ventilation function shown in FIG. 1 and FIGS. 9A and 9B includes a void 2, a ventilation void tube 3, a ventilation short tube 4, and an opening / closing in parallel in the short side direction built in the concrete. Each individual ventilation route can be freely set at any time according to the difference in the configuration of the pipe system comprising the valve 5.
Of course, because it is a void slab with a built-in pipe system in the concrete, it is not necessary to install a ventilation duct separately, and it is necessary to set and change the ventilation route not only at the time of construction but also after renovation, renewal, etc. It is possible to change the ventilation equipment and to set the route by the on-off valve 5 easily, including changing or updating the ventilation route.
