Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention has a ratio Ea / Eb of 1.8 or more between the axial rigidity Ea of a column and the axial rigidity Eb of a vertical frame material of a large wall panel. By the following, the house of the frame construction method, the house of the panel construction method,
The present invention relates to a house construction structure in which members can be integrated by using it in a house of a frame or panel construction method.

[Conventional technology]

Conventionally, there are a frame construction method and a panel construction method as a construction method for constructing a prefabricated house in which construction members are produced in advance in a house, particularly a factory.

The frame construction method means, for example, in the case of a two-story building, as shown in FIG. 25, floor beams b and roof beams c that form a gap between through columns a.
After assembling the frame structure d by using, etc., the wall panels e ... Are attached to the frame structure d. In the house of the frame construction method, the pillars a, the beams b, c, etc. are members made of steel, and since the frame structure d has high strength and excellent rigidity, it is attached to the frame structure d. The wall panel e generally does not need to withstand strength, and therefore, in order to reduce the weight and improve the handleability such as construction, for example, a frame made of a combination of wooden frame members is used, and its width is It is formed as a small wall panel having a width of about 1 to 3 times that of the reference module M.

The frame structure d itself of this frame construction method is also roughly classified into a frame structure and a pin structure.

As shown in Fig. 27, the ramen structure means pillars a and beams b.
In this structure, it is necessary to increase the rigidity in the axial direction of the column a, while the beam b is to be rigidly joined. The axial rigidity of is characterized by being relatively small.

As shown in FIG. 28, the pin structure means that the pillars a and the beams b are joined by pins, and the horizontal force is reinforced by the braces f diagonally laid on the vertical and horizontal planes. Since the horizontal force can be carried by the brace f, the rigidity of the column a in the axial direction can be reduced.

On the vertical wall surface, the brace f is formed as a load bearing panel g in which the brace f is incorporated into the wall panel e, and is rigidly joined to the beams b, c, the foundation h, etc., as shown in FIG. The load-bearing panel g is also used for the frame structure d of the rigid frame structure to reinforce the frame structure d and also help to reduce the cost as a whole.

On the other hand, in the panel construction method, as shown in FIG. 26, the house is assembled by connecting the wall panels e with the connecting fittings i. In addition, in this panel construction method, the downstairs wall panel e1
Are reinforced by placing a floor beam b in the shape of a barrel and a roof beam c on the wall panel e2 on the upper floor.

Further, in this panel construction method, since it is premised that no columns are used, the wall panel e uses a frame in which a steel frame member is arranged in a rectangular shape, and a vertical axial force is exerted by the vertical frame member. That is, the axial force is borne. Regarding horizontal force,
In addition to the stress-skin construction method in which the face materials attached to the front and back of the frame are used for supporting, there is also a method using a wall panel incorporating a brace f shown by a broken line. Although the panel by this stress skin method is easy to manufacture, it is restricted by the position and size of the opening provided in the wall panel e.

Although this panel construction method can make the assembly extremely efficient and can reduce the construction cost, since the weight of the wall panel is large, the machine assembly construction using a crane or the like is a prerequisite. On the other hand, in this construction method, since it is premised on the machine assembly work, the wall panel e is three times as large as the reference module M.
A large wall panel with an extremely wide width of about 6 times is adopted.

Therefore, in the frame construction method, no machine assembly work is required, and in contrast to the site conditions not being required, the panel construction method requires the use of cranes, etc. There are also differences such as the ease of addition and the difficulty of extension and renovation with the panel construction method.

Conventionally, the above-mentioned frame construction method and panel construction method have been systematized as independent series, respectively, and it is not intended to use a building member of a house of each construction method for one house to form a composite house.

As a result, the building members of the house in each part, including the balcony and veranda in the frame construction method, and the building members of the house in the panel construction method lack commonality, and it is necessary to design and produce them separately. It takes time for logistics, inventory management, etc.
It will be inferior in productivity.

In each construction method, when adopting a heavy roof different from the standard, a wall panel such as a heavy concrete panel on the upper floor, according to the request of the construction owner, and also in a house constructed in a snowy area, etc., Reinforcement construction with different contents is required for each construction method, such as when a load larger than the standard load is applied, making a series of operations such as design and construction complicated.

 There are issues to be solved.

Therefore, by integrating the beams, columns, connecting fittings, etc. in the frame construction method and panel construction method, the so-called frame construction method,
We have devised a panel construction method, a framework that arranges columns between large-scale wall panels, and a house construction structure that enables building a panel construction method.

[Problems to be Solved by the Invention]

However, at this time, it is premised that the panel construction house and the frame construction house constructed by using the integrated members are substantially equal in strength.

The present invention, by using a fixed ratio of rigidity in the axial direction for the pillar and the vertical frame material of the large-sized wall panel,
The purpose is to balance the strength of the house of the frame construction method and to provide the house construction structure that can build the house of the frame and panel construction method which is excellent in the strength.

[Means for solving the problem]

The present invention uses a large wall panel having a wide frame made of steel and a vertical column, in which vertical frame members for axial load are laid across both ends of a horizontal upper frame member and a lower frame member, The house construction structure has a ratio Ea / Eb between the axial rigidity Ea of the pillar and the axial rigidity Eb of the vertical frame member of 1.8 or more and 6 or less.

[Action]

The ratio Ea / Eb of the axial rigidity Ea of the pillar and the axial rigidity Eb of the vertical frame member of the large wall panel is set to 1.8 or more and 6 or less.
As a result, for example, the total axial rigidity (2 × Eb) of two adjacent vertical frame members of large-sized wall panels built side by side by the panel construction method and the axial rigidity of the column of the rigid frame structure in the frame construction method. The ratio Ea / 2 · Eb with Ea can be 0.9 or more and 3 or less. Therefore, when a house of the frame construction method and the panel construction method is constructed using the large wall panel having this vertical frame material and the pillar, the strength balance in the house of both construction methods can be substantially matched and the frame construction method can be used. Even if the panel construction method is partially used for the house, or conversely, the frame construction method is partially used for the panel construction house, the strength balance of the entire house can be maintained.

When the ratio Ea / Eb is larger than 6, the rigidity of the column in the axial direction becomes excessively higher than the rigidity of the vertical frame member in the axial direction, which impairs the strength balance of the frame construction method and the panel construction method. When columns are partially provided between adjacent vertical frame members of juxtaposed large wall panels in the panel construction method, the total axial rigidity (2 × Eb) of these two vertical frame members and the column axis Rigidity (Ea) and total rigidity (2 × Eb + Ea), and ratio of axial rigidity (2 × Eb) (2 × Eb) of the part that does not have a column, that is, the portion that bears the axial force with only two vertical frame members ( 2 x Eb + Ea) / (2
XEb) is larger than 4, so the strength balance between the total axial rigidity (2 × Eb + Ea) of the part where the column is provided and the total axial rigidity (2 × Eb) of the part where the column is not provided is matched. Therefore, the integration of members including columns and vertical frame members cannot be achieved. Therefore, by setting the ratio Ea / Eb to 6 or less, the strength balance of the entire house can be maintained by suppressing the axial rigidity ratio to 4 or less, even if columns are partially used in the panel construction method, for example. .

On the contrary, if the ratio Ea / Eb is smaller than 1.8, the ratio Ea / 2 · between the total axial rigidity (2 × Eb) of the two adjacent vertical frame members and the axial rigidity Ea of the column Eb is smaller than 0.9, and the axial rigidity of the house of the frame construction method is too small compared to the house of the panel construction method, so the strength balance in the houses of both construction methods cannot be substantially matched. When pillars are placed between the large wall panels in, the ratio (Ea + 2 × Eb) /
Since (2 × Eb) becomes smaller than 1.9, it is impossible to construct a house with a frame and panel construction method that has approximately twice the axial rigidity by providing columns.

As described above, the panel construction method, the frame construction method, or the building construction member of the house in which the panel construction method and the frame construction method are combined can be made common and integrated, and the labor for designing, manufacturing, etc. can be largely omitted, and The productivity of house construction can be improved by enabling the systemization and compounding of.

The axial rigidity is defined as the product EA of the Young's modulus E and the cross-sectional area A, as is well known.

The load-bearing panel PF is a beam 4 using the joint fittings 5 and 5 described above.
Further, both ends thereof can be connected by bolts, and can be fixed to the foundation D and the mounting piece 47A at the upper end of the floor beam 4a by the mounting holes provided in the leg pieces 26.

The pillar 3 includes a through pillar 3A shown in FIG. 18 (a) for forming a multi-storey house, and a first floor pillar 3B shown in FIG. 18 (b) for forming a single-story building.

The through pillar 3A has horizontal fixing plates 32, 32 at the upper and lower ends of a base 31 made of a square steel pipe having a length from the upper surface of the foundation D to the upper end of the roof beam 4B and having the same outer peripheral surface as the base piece 61 of the connecting fitting 6. It is provided.

Further, the pillar 3A has holes 32 provided in the upper and lower fixing plates 32.

Has been drilled. As described above, the pillar 3A has the same panel mounting portion J as the panel mounting portion J of the connecting fitting 6 by providing the hole portion 31a aligned with the mounting hole 29a of the large wall panel PL. It can be used by arranging it in the gap K by replacing it with the connecting fitting 6.

In the case of a one-story building, the first-floor pillar 3B is a wall panel below
Since the roof beam 4B is directly placed on the upper end of PS, the height is set to reach the upper end of the roof beam 4B, and the panel mounting portion J is similarly formed.

 Further, the pillar 3 may include a tube pillar 3C shown in FIG.

The tube column 3C has the same structure as the through column 3A except that the height thereof is almost the same as that of the large-sized wall panel PL, and the notch holes 33, 33 are provided on the upper and lower sides of the substrate 31, and at the upper end of the substrate 31. Fixed plate
32 is provided with a hole 32a, and the base 31 is provided with a panel mounting part J having a hole 31a which can be aligned with a mounting hole 29a provided on the side end surface of the large wall panel PL.

Are used on the upper floor and the pipe pillar 3C is used on the lower floor, and the pipe pillar 3C is used on the upper and lower floors in FIG. 14, are shown in comparison with each other. Thus, it is obvious that the strength of the portion can be improved by arranging the tube columns 3C on the lower floor, for example.

[Explanation of column strength]

In this way, the pillar 3 is shared by the house HB of the frame construction method and the house H of the frame and panel construction method.

On the other hand, it is necessary that the building HA of the panel construction method using the connecting fittings 6 and the frame construction method HB using the columns 3 have substantially the same building rigidity.

Therefore, as shown in FIG. 19 (a), when the large wall panels PL, PL are juxtaposed with a gap K in the panel construction method, a panel construction method obtained by the vertical frame members 21c, 21c sandwiching the gap K In order to make the rigidity of the house HA in the axial direction substantially equal to the rigidity of the pillar 3 in the axial assembly method shown in FIG. 19 (b), the rigidity of the pillar 3 in the axial direction Ea,
The ratio Ea / Eb of the vertical frame member 21c to the axial rigidity Eb is set to 1.8 or more and 6 or less. As a result, even when the large wall panels PLB and PLB having the framework pLB without the diagonal members 24 are juxtaposed, the total axial rigidity (2 × Eb) of the two vertical frame members 21c and 21c, The ratio of the axial rigidity Ea of one pillar 3 to 0.
By setting it to 9 or more and 3 or less, it is possible to almost balance,
The pillar 3 can be shared even when the building members of the house of each construction method are mixed. Further, even if the panel construction method is partially adopted in the house of the frame construction method and conversely, the frame construction method is partially adopted in the house of the panel construction method, the strength balance of the whole house can be maintained.

The ratio Ea / Eb is preferably 2 or more and 4 or less. In order to improve the axial rigidity Ea of the pillar 3,
It is preferable to increase the plate thickness of the pillar 3 or arrange an appropriate stay (not shown) inside.

When the ratio Ea / Eb exceeds 6, the pillar 3 has an excessive quality, and when it is smaller than 1.8, the building rigidity of the house HB of the frame construction method is reduced as compared with the house HA of the panel construction method.
In the house HB of the frame construction method, the ratio Ea / Eb is 1.8 or more and 2 by appropriately dispersing the load bearing panels PF.
It is possible to set the range to the following, and it is possible to equalize the building rigidity of houses.

[Common height]

Further, in the house H of the frame and panel construction method, it is possible to mix the large wall panel PL and the small wall panel PS, and in order to facilitate the extension and remodeling, as shown in FIGS. The height H1 between the floor beam 4A and the lower surface of the floor beam 4A and the height H2 between the upper surface of the floor beam 4A and the lower surface of the roof beam 4B are the same when the large wall panel PL and the small wall panel PS are used. And As shown in FIG. 21 and FIG. 23, the mounting bracket 13 for mounting the floor panel PL is fixed to the upper surface Db of the foundation D. Therefore, the height H1 is equal to the plate thickness H3 of the mounting bracket 13. , Set higher than the height H2. As a result, it is possible to use a large-sized wall panel PL with the same size on the lower floor and the upper floor, and also to use a small-sized wall panel.
PS can be installed in common.

[Summary and other examples]

Thus, the vertical rigidity ratio Ea / of the pillars used for the houses HA and HB of the panel construction method and the frame construction method and the vertical frame member 21c of the large wall panel PL
By setting Eb in the above range, it is possible to construct the homes HA and HB of the panel construction method and the frame construction method with balanced strength. In addition, the framework in which the pillars 3 are arranged between the large-sized wall panels PL, the house of the panel construction method has a significantly improved strength and can withstand a large load.

Furthermore, as shown in FIG. 4, it is possible to mix the pillar, the large wall panel PL, and the small wall panel PS integrated as described above in the same floor portion.

In the house H shown in FIG. 4, a bulging portion Ha having a plurality of wall panels P inclined in a V-shape is protruded from the house main body Hb. In addition, a flat building portion Hc is formed in the house body Hb.

In the lower part of the house Hb, on the right side of the figure is the above-mentioned pipe pillar.
An outer wall is formed by arranging a large wall panel PL having a beam 4A and an upper surface between 3C. Further, as shown on the left side of the figure, the outer wall is formed by arranging the small wall panels PS, PS between the frame structures F in which the roof beams 4B are bridged over the upper ends of the through columns 3A, 3A, as shown on the left side of the figure. To be done. In addition, the one-story building Hc is a pillar
Frame structure F consisting of 3B and roof beams 4B, small wall panel PS ...
Are arranged.

In the interior of the house, load-bearing panels PF are used.

The bulging portions Ha are formed by using the large-sized wall panel PL3, the small-sized wall panels PS1, PS2, and are inclined in a dogleg shape and are juxtaposed with a gap N between the bent portions. , Connect using the connecting fittings for diagonal connection,
Further, the connecting beams 4a, 4b, 4c are connected.

As described above, the house building structure of the present invention can build a house H having a frame structure and a panel construction method that are matched in strength. Therefore, when the house shown in FIG. 1 is formed by using the pillars 3, the beams 4, and the large-sized wall panel PL, and when other building members are used, the large-sized wall panel in each part of the first floor shown in FIG. 4 is used. It is also possible to build a house that mixes PL and small wall panel PS.

Further, it is possible to construct a house as shown in Table 1 which is properly used according to the purpose.

In Table 1, “Large pa” indicates the large wall panel PL, and “Small pa” indicates the small wall panel PS. Furthermore, "there is a pillar on the 1st floor" and "having a pillar on the 2nd floor" means that the pipe pillar 4C is used in the lower floor and the upper floor. Further, "through pillar" means that a through pillar 4A extending from the lower floor to the upper floor is used. The first
The second row from the top of the table shows the types of wall panels used on the first floor, and the second row from the left shows the types of wall panels used on the second floor.

Therefore, in Table 1, (i) shows the through pillar 3A. In addition to using the large wall panel PL on the upper and lower floors,
It means a house H of the framework and panel construction method shown in FIG. Further, for example, (a) in Table 1 means the case shown in FIG. 14 in which the pipe columns 4C are used for the first and second floors and the large wall panel PL is used for the upper and lower floors, and ( b)-
1 to (k) show the same contents.

As described above, it is possible to construct these types of houses by using the integrated building members for the house.

In Table 1, the structure (a) is used for a three-story building, such as a snowy area where large axial forces act on both the lower and upper floors, when the roof weight is large, and when there are three stories. Since a large-sized wall panel is used, the machine assembly work is premised, as is the case with other large-sized wall panels.

The structure of (b) -1 is a case where a large axial force acts on the lower floors, but a large axial force does not act on the upper floors such as using a lightweight roofing material. Used when needed.

The structure of (b) -2 can be suitably used when it is necessary to renovate the lower floor.

The structure (c) has the structure shown in FIG. 13, and can be adopted when the axial force acting on the lower floors is large and the load on the upper floors is small.

The structure of (d) can be suitably used when the expansion and renovation of the first floor is required.

The structure of (f) is suitable when the axial force of the upper floor is large and is suitable for the extension and renovation of the upper floor.

The structure (g) means the panel construction method shown in FIG.

The structure of (h) can improve the flexibility of the construction by connecting the upper floor and the lower floor with the pipe pillar 4C, and can be used when the axial force is small.

As described above, the structure of (i) is the house H shown in FIG.
And can carry the greatest axial force.

The structure of (j) -1 can be used when it is necessary to renovate the upper floors.

(J) -2 can be used when it is necessary to renovate the lower floors.

The structure of (k) is a house of the frame construction method shown in FIG. 3, and can be used when it is necessary to add or renovate both the upper floor and the lower floor, or when it is difficult to construct the machine.

〔The invention's effect〕

The ratio Ea / Eb between the axial rigidity Ea of the pillar and the axial rigidity Eb of the vertical frame member of the large wall panel is set to 1.8 or more and 6 or less. Therefore, the total axial rigidity (2 x Eb) of two adjacent vertical frame members of a large wall panel juxtaposed in a panel construction house.
And the axial rigidity Ea of the column in the house of the frame construction method
Ea / (2 × Eb) can be 0.9 or more and 3 or less,
While the strength balance of the houses of both construction methods can be roughly matched,
It is possible to partially adopt the panel construction method in the house of the frame construction method and conversely to partially adopt the frame construction method in the house of the panel construction method without impairing the strength balance.
Also, by providing a pillar between the large wall panels, the total axial rigidity (Ea + 2 x Eb) should be 1.9 to 4 times the total axial rigidity (2 x Eb) of only two vertical frame members. Can
The strength of the house that uses both the frame and panel construction methods can be increased.

In this way, it becomes possible to standardize and integrate building construction members such as a frame construction method, a panel construction method, a mixture of both construction methods, or a house that uses both construction methods, and the labor of designing, manufacturing, etc. can be greatly omitted. By enabling the systematization and compounding of members, the productivity of house construction can be increased.
