Description

TECHNICAL FIELD The present invention relates to a rectangular parallelepiped unit for a house, which has improved workability during assembly and improved strength after assembly.

[Conventional technology]

This type of housing rectangular unit is a unit made by dividing each room of the house, and each unit is assembled in advance on a factory production line and then transported to the construction site to assemble the units to create a single house. Is completed.

As shown in FIG. 7, generally, this type of housing rectangular parallelepiped unit 1 is composed of a ceiling panel 3, a floor panel 5, a pair of gable panels 7, and the like.

The ceiling panel 3 and the floor panel 5 each have a beam 10 (chamber) having a U-shaped cross section on both side edges in the longitudinal direction.
A gypsum board, a wood-based particle board, a heat insulating material, or the like is fixed so as to close the gap between the beam 10 and the beam 10 to form a single panel.

On the other hand, the gable panel 7 has a pair of square pipe-shaped columns 18 arranged at a predetermined interval, and both columns are connected and integrated by a pair of beams 20.

Then, the ceiling panel 3, the floor panel 5, and the wife panel 7
Beams of the ceiling panel 3 and the floor panel 5 at the time of joining with
This is done by bolting both longitudinal end portions of 10 and the pillar 18 of the end panel 7.

That is, as shown in FIG. 8 and FIG. 9, a plate-shaped iron inner plate 9 having a bolt hole 9A penetrating in the thickness direction is welded and fixed to the inner surface of the column 18.
18 and the beam 10 have a bolt hole 11A penetrating in the thickness direction, and are abutted via a plate-shaped iron end plate 11 which is welded and fixed to the end face of the beam 10 in advance, and the inner plate 9 and the end are connected. The pillar 18 is fastened by fastening the plate 11 with bolts 30.
And the beam 10 are joined and integrated.

In order for the housing rectangular parallelepiped unit 1 assembled in this manner to have an accurate rectangular parallelepiped shape, the beam 10 and the pillar 18 are required.
It is necessary that the and are abutted vertically, in which case the strength of the assembled unit is at its best.

[Problems to be Solved by the Invention]

By the way, it is technically difficult and takes a lot of time to form the beam 10 so that the side surface of the column 18 and the longitudinal direction of the beam 10 are perpendicular to each other. In other words, when welding the end plate 11 to the end surface of the beam 10, the end surface of the beam 10 is
It is necessary to make an exact right angle with respect to the longitudinal axis of the cutting and to cut it. The longer the length of the beam 10, the more difficult it is to obtain good accuracy, and this right angle is also large in terms of cost. It will be a burden.

Therefore, when the end surface of the beam 10 is brought into contact with the column 18, the longitudinal direction of the beam 10 and the longitudinal direction of the column 18 are not always orthogonal to each other in many cases.

Therefore, when the end plate 11 and the pillar 18 are forcibly brought into contact with each other, an unreasonable force may be applied to other portions such as the beam 10, and one end surface of the beam 10 is closely attached to the pillar 18. Then, the other end face may not be brought into close contact with the column 18, which may cause inconvenience.

As a result, the standing rectangular parallelepiped unit 1 for housing may not hold the rectangular parallelepiped shape accurately, and unreasonable force is applied to the beams 10 and the pillars 18, so that the strength of the entire unit 1 is in the best condition. It may disappear.

Also, as can be understood from FIG. 8, the end plate
Two of the bolt holes 11A provided in 11 are located on the rear side of the beam 10, so that the gypsum board or particle board fixed to the ceiling panel 3 and the floor panel 5 is a pillar 18
The beam cannot be fully stretched before installation on the beam 10
Only after the fixing of the board to the pillar 18, that is, after the tightening of the bolt is completed, the board can be finally fixed to the panels 3 and 10.
Therefore, the degree of completion of the panels 3 and 10 in the panel manufacturing line is low, and the number of man-hours in the assembly line is correspondingly increased, resulting in a decrease in overall work efficiency.

An object of the present invention is to provide both ends in the longitudinal direction of the beam 10 and the column.
(EN) It is intended to provide a rectangular parallelepiped unit for a house, which can easily come into vertical contact with 18 side surfaces.

And fixed with bolts or the like.

〔Example〕

Hereinafter, preferred embodiments of a rectangular parallelepiped unit for a house according to the present invention will be described with reference to the drawings.

FIG. 1 shows a housing rectangular parallelepiped unit (hereinafter simply referred to as a unit) 1 according to the present invention.

In the figure, the unit 1 includes a plate-like ceiling panel 3 and a plate-like floor panel 5 disposed at a position separated from the ceiling panel 3 by a predetermined distance so as to face the ceiling panel 3, and the ceiling panel 3 and the floor panel 5. And a pair of gable panels 7 and 7 joined to and integrated with.

The ceiling panel 3 has beams 2 and 2 having a substantially U-shaped cross section, which are arranged to face each other along both side edges in the longitudinal direction, and a predetermined space is provided between the beams 2 and 2 along the longitudinal direction of the ceiling panel 3. A plurality of steel rims 4, 4 ... Are arranged side by side at intervals.

Both longitudinal end faces of each field edge 4 are fixed by welding to opposite side faces of both beams 2, 2.

Further, in each opening 4A between the adjacent field edges 4, 4, ..., Gypsum board 6 that closes the opening 4A, and rock wool 8 as a sound insulating / heat insulating material that is placed on the upper surface of the gypsum board 6
Are arranged respectively. Furthermore, an X-shaped brace 8A is provided as needed.

The floor panel 5 has beams 10, 1 with a substantially U-shaped cross section on both side edges in the longitudinal direction.
0, and in the longitudinal direction of the floor panel 5, both beams 10,
A plurality of steel joists 12, 12 ... for connecting the 10 are arranged side by side. Both end faces of each joist 12 are fixed to opposite side faces of both beams 10, 10 by welding.

Particle boards 14 are laid on both upper and lower sides of the floor panel 5 in the thickness direction.
A foamed heat insulating material 16 is interposed therebetween, so that the floor panel 5 is a substantially plate-shaped body.

The gable panel 7 is a beam 2 having a substantially U-shaped cross section between the end portions of the pair of prisms 18, 18 arranged at a predetermined interval, which are opposed to each other.
It is formed into a rectangular shape by connecting by 0 and 20 by welding. At this time, since the lengths of the beams 20, 20 are short, the accuracy of the squareness with respect to the longitudinal axis of the beams at the time of cutting the end face is not so required, and direct welding does not cause any problem.

In addition, for example, a partition panel 22 or the like can be attached to the opening portion of the wife panel 7 if necessary.

The ceiling panel 3, the floor panel 5, and the end panel 7 are configured as described above, and the unit 1 is assembled by joining all these panels.

The joining of the panels is performed by bolting the longitudinal ends of the beams 2, 2, 10, 10 of the ceiling panel 3 and the floor panel 5 to the columns 18 of the gable panel 7.

Here, FIG. 2 shows an exploded perspective view of the connection structure at the joint between the beam 10 and the pillar 18, and FIG. 3 shows a sectional view showing the connection structure.

As can be seen from FIG. 3, the inner surface of the pillar 18 is
Similar to the conventional example shown in the figure, a plate-shaped inner plate 9 having four bolt holes 9A formed therein is fixed by welding.
It is positioned so as to face the formation position of 18A.

And, as can be seen from FIGS. 2 and 3,
At both ends of the beam 10, plate-like end plates 11 are partly protruded from the ends of the beam 10 and fixed by welding. As will be understood from FIG. 4, in each end plate 11, the end face of the beam 10 is not perpendicular to the longitudinal direction of the beam 10, for example, one end face is offset by α and the other end face is offset by β. In this case, the end plate 11 is positioned and fixed at a right angle with respect to the longitudinal axis of the beam 10 by using a jig or the like, so that the end face of the beam 10 (end face of the end plate 11) and the pillar 18 are fixed. Can be exactly orthogonal to the longitudinal direction. In addition, the length l in the longitudinal direction of the beam 10 is accurately and easily maintained corresponding to the distance between the gable panels 7, 7.

Therefore, the entire end surfaces of the beam 10 are in close contact with the column 18.

A bolt hole 11A is formed through the end plate 11 at a position corresponding to the bolt hole 18A. Further, four hollow rectangular parallelepiped box-shaped nut holders 13 are fixed to the inner plate 9 by welding in correspondence with the positions where the bolt holes 9A are formed, and the high torque nuts 15 are loosened in the nut holders 13. Has been inserted. The nut 15 has a rectangular parallelepiped shape slightly smaller than the inner peripheral shape of the nut holder 13 so that the nut 15 is just stored in the box-shaped nut holder 13 and is prevented from rotating.

Therefore, from the beam 10 side, insert the high torque bolt 17 into the bolt hole 11
The beam 10 and the column 18 can be firmly joined by being inserted into A, 18A and 9A and screwed and fastened with the high torque nut 15.

Further, in this embodiment, as can be understood from FIGS. 5 and 6, a reinforcing piece 19 for connecting the end plate 11 and the end face on the opening side of the beam 10 is fixed by welding if necessary.

As a result, the beam 10 and the pillar 18 are more firmly joined to each other, and as a result, the strength of the assembled unit 1 is greater.

In addition, the connection of the beam 2 and the pillar 18 in the ceiling panel 3,
Since the bonding is performed in the same manner as the beam 10 and the pillar 18, the description thereof will be omitted.

As described above, in this embodiment, the end plate
Both end surfaces of the beam 2 and the beam 10 are properly brought into close contact with one side surface of the pillar 18 of the gable panel 7 via 11.

As a result, the beam 2 and the like can be easily positioned during assembly,
Assembly work efficiency is improved.

Further, the assembled unit 1 has a substantially accurate rectangular parallelepiped shape, and therefore the strength of the unit 1 is extremely excellent.

Furthermore, the end plate 11 has the beams 2, 10 as in the conventional example.
Since it is not welded to the end faces of the beams 2 and 10, it is not necessary to consider the squareness of the end faces when cutting the end faces of the beams 2 and 10. Can be significantly reduced. In addition, the end plate 11 includes the beams 2,
Since it is located inside the column 10 and the column 18, when the end plate 11 is welded and fixed to the beam 2 or the beam 10, no trace of welding remains on the outer surface of the unit 1. There is no need for work such as smoothing.

As a result, the assembly workability and productivity of the unit 1 are further improved.

Further, since the end plate 11 is configured to be fixed inside the beams 2 and 10, the bolt holes 11A are located on the open side of the U-shaped beams 2 and 10 as can be understood from FIG. are doing. Therefore, even if the gypsum board 6 is stretched over the ceiling panel 3 and the particle board 14 is stretched over the floor panel 5, the beams 3, 10 of the panels 3, 5 are not fixed to the pillars 18 at all. Does not mean As a result, each panel manufacturing line
Since 3 and 5 can be completed, it is possible to improve the work efficiency of the entire production line and reduce costs.

In the housing rectangular parallelepiped unit according to the present invention, the configuration of each part is not limited to the above-mentioned embodiment, and other configurations may be adopted.

For example, the end plate 11 does not necessarily have to protrude from the end faces of the beams 2 and 10, and at least the end plate 11
The outer end surfaces of the beams 2 and 10 may be flush with or project from both end surfaces in the longitudinal direction of the beams 2 and 10, and the point is that the attachment of the beams 2 and 10 to the column 18 is restricted by the end surfaces of the end plates 11. It can be done as follows.

Then, the nut holder 13 is not always necessary, and it is also preferable to fix the nut 15 and the bolt 17 using a tool such as a box spanner, and in a state where the nut 15 is fixed to the inner surface of the column 18 by welding or the like. A configuration in which the bolt 17 is screwed is also suitable.

Furthermore, the beams 2 and 10 are not limited to channels having a substantially U-shaped cross section, and other cross-sectional shapes such as C channels can be used.

[Effects of the Invention] As can be understood from the above description, in the rectangular parallelepiped unit for a house according to the present invention, the beam and the prism are contacted via the end plates positioned and fixed inside both ends in the longitudinal direction of the beam. Contacted. Therefore, the longitudinal direction of the beam and the longitudinal direction of the prism are substantially exactly orthogonal to each other, and as a result, the assembled rectangular parallelepiped unit for housing has a more accurate rectangular parallelepiped shape and has the best strength after assembly. The effect is that it can be put into a state.

For the present invention, the IPC is changed to "E04B 1/24, E04B 1/5
4, E04B 1/58 ”, the keyword is“ column, beam, joint, end,
When a so-called Patrice search was performed for "end plate" and the like, no "residential rectangular parallelepiped unit" like the present invention was found, and the novelty of the present invention in the relevant field was clarified.
