Description

  The present invention relates to a hut structure in a house with a gable roof and a house that employs the shed structure.

  Conventionally, by securing the ceiling height of the attic space, in order to effectively use the attic space, a plurality of auxiliary pillars are installed on a pair of eaves beams arranged in parallel to each other. There has been proposed a roof structure in which a horizontal member is stretched over an auxiliary column and a gradient beam is joined to the horizontal member (see Patent Document 1 and Patent Document 2).

  By configuring in this way, compared to the case where the gradient beam is directly joined to the beam, the height of the auxiliary column and horizontal member can be increased, and the height of the gradient beam and the roof base can be increased. Since the back ceiling height can be ensured, a hut space with a large volume can be obtained.

  However, the above-mentioned roof structure has a plurality of auxiliary pillars standing on the eaves girder, and further crosses the horizontal member. Therefore, compared to a structure in which a gradient beam is simply joined to the eaves girder, The number increased, and there was a problem that the construction man-hour increased.

  In addition, in the above-mentioned roof structure, the eaves girder beam is the same as the normal roof structure, so it is necessary to displace the horizontal position of the expressed roof beam and the expressed gradient beam, for example, in the case of providing an atrium. There was a possibility that the design of the atrium portion could be miscellaneous.

  Furthermore, since the height of the lower surface of the eaves girder is substantially the same as the height of the lower surface of the roof beam, it is difficult to provide a long opening in the height direction.

  Therefore, the present invention is a hut assembly structure that can secure a sufficient ceiling height on the back of the hut without increasing the number of parts and the number of construction man-hours, and can improve the design in the case of providing an atrium. An object of the present invention is to provide a roof structure and a house that can be provided with a long opening in the height direction on the lower floor.

The shed structure according to claim 1 is a shed structure with a gable roof having a living space at the back of the shed, and an eaves girder that receives rafters on the eaves side, and a shed beam whose end is fixed to the eaves girder When, and a slope beam whose ends are fixed to the eaves digit the eaves digit lower surface rather higher than the lower surface of the tie beam, and the upper surface of the eaves digits than the upper surface of the tie beam It is constructed so as to be high , and a floor surface is provided on the shed beam, and the eaves girder has a beam bar capable of joining the shed beam and the gradient beam at the same position in the horizontal direction, On the side surface of the eaves girder, the first beam receiver and the second beam receiver are fixed in the same position in the horizontal direction, and the gradient beam is joined to the first beam receiver. The shed beam is joined to the second beam receiver .

  According to the shed structure of claim 1, the eaves girder has a beam that can join the shed beam and the gradient beam at the same position in the horizontal direction. Since the shed beam and the gradient beam can be joined with the required strength without shifting the position in the horizontal direction, the design of the blow-by portion can be improved. Moreover, since the eaves-girder is constructed so that the lower surface of the eaves girder is higher than the lower surface of the shed beam, the design freedom in the height direction of the opening on the lower floor of the shed can be increased. The eaves girder has a beam lower surface that is higher than the lower surface of the shed beam and has a beam that can join the shed beam and the gradient beam at the same position in the horizontal direction, so that only the shed beam can be bonded. Compared with conventional eaves girders with beams, the upper surface of eaves can be positioned higher, and the hanging lumber fixed to the upper surface of eaves can be made higher than before, so the number of parts and construction Without increasing the number of man-hours, the height of the roof can be increased, and a sufficient ceiling height can be secured in the back of the hut.

As shown in FIG. 2, the eaves girder 7 is a square bar having a vertical height, that is, a beam length L ₁ of 450 mm and a width L ₂ of 120 mm on the fore edge surface. The length of the eaves girder 7 is such a length that both ends of the eaves girder 7 can be fixed between through pillars erected at both ends of the eaves of the house 2, and is not particularly limited. is there. A first beam receiver 15 for the horizontal shed beam 12 and a second beam receiver 16 for the gradient beam 13 are fixed to the eaves beam 7 by bolts 17 and nuts 18. Since the first beam receiver 15 and the second beam receiver 16 are known beam receivers, a detailed description thereof is omitted. However, the first beam receiver 15 and the second beam receiver 16 are fixed to the eaves girder 7 with bolt holes (not shown). It consists of pieces 19a, 19b and two protruding pieces 20a, 20b protruding from both sides of the fixed pieces 19a, 19b toward the shed beam 12 or the gradient beam 13, and the drift pin 22 is provided above the protruding pieces 20a, 20b.

In this hollow portion, the shed beam 12 and the gradient beam 13 become visible beams that can be seen from the first floor. ing.

Thus, by beam depth L ₁ of pole plate 7 is 450 mm, fixed side by side vertically at the same position as the first beam hangers object 15 and a second beam hangers object 16 in the horizontal direction to pole plate 7 Therefore, it is possible to join the roof beam 12 and the gradient beam 13 with the required strength without shifting the horizontal position of the roof beam 12 and the gradient beam 13 in the atrium that penetrates from the first floor to the back of the cabin 4. Therefore, it is possible to improve the design of the blow-by portion.

  When the roof beam 12 is fixed to the eaves girder 7, as shown in FIGS. 3A and 3B, first, the roof beam 12 is moved to a crane or the like without the drift pin 22 inserted into the drift hole 24a. Then, the vertical groove formed on the facet of the shed beam 12 passes through the protruding piece 20b of the second beam receiver 16. Then, after passing through the second beam receiver 16, the drift pin 22 is inserted into the upper drift hole 24 a provided on the side surface of the cabin beam 12, and the protruding piece 20 a of the first beam receiver 15 is inserted. The drift pin 22 is locked in the locking groove 21 provided in the upper part. Next, the drift pin 22 is inserted into the insertion hole 23 provided in the lower drift hole 24 a of the roof beam 12 and the protruding piece 20 a of the first beam receiver 15, and the roof beam 12 is fixed to the eaves beam 7. When the gradient beam 13 is further fixed to the eaves girder 7, the drift pin 22 is inserted into the upper drift hole 24b provided on the side surface of the gradient beam 13, as shown in FIGS.

  When the roof beam 12 is fixed to the eaves beam 7, the lower surface of the roof beam 12 is disposed at a position 120 mm lower than the lower surface of the eaves beam 7. Further, the upper surface of the roof beam 12 is disposed at a position lower by 300 mm than the upper surface of the eaves girder 7. Below the shed beam 12 is a first-floor structural frame. The structure of the first-floor structure is well known in the art and will not be described here. However, since the roof beam 12 can be installed at a conventional height, the first-floor column 6 below the beam 12 and the like. Conventional structural bodies and outer wall materials can be used as they are.

In this way, the eaves girder 7 according to the shed structure 1 of the present embodiment has the beam eaves L _{1 of} 450 mm, and is a eave girder 7 having a larger beam eaves than in the prior art, so FIG. As shown in FIG. 4, the height of the upper surface of the eaves beam 7 is 300 mm higher than the upper surface of the roof beam 12 (L ₃ ). Also, as shown in FIG. 4 (b), the conventional eaves girder 7 'is a fit for bringing the rafters 14 into contact with the upper surface of the eaves beam 7 and the upper surface of the roof beam 12, so that the upper surface of the eaves beam 7 is It was disposed 90 mm lower than the upper surface of the shed beam 12 (L ₄ ). Therefore, the upper surface of the eaves 7 according to the roof structure 1 of the present embodiment is 390 mm higher than the conventional eaves 7 ′. And since the rafter 14 is fixed to the upper surface of the eaves girder 7, the roof structure 1 of this embodiment can make the whole roof 390 mm high, without changing a roof gradient. Since the height of the floor surface 25 in the living space 3 of the shed 4 is defined by the height of the shed beam 12 functioning as a floor beam, the ceiling height of the living space 3 of the shed 4 is the conventional hut. It is 390 mm higher than that of the assembly structure 1.

  In addition, although the height of the upper surface of the eaves girder 7 is 300 mm higher than the upper surface of the roof beam 12 in this embodiment, it is not limited to this. What is necessary is just to become 125 mm or more higher than the upper surface.

Therefore, since the average ceiling height of the living space 3 in the shed 4 can be increased, for example, even if the house 2 has a frontage of about 9 m, the average ceiling height of the living space 3 in the shed 4 is increased. 2.1 meters or more can be secured and it can be used as a living room. Further, as shown in FIG. 5 (a), the lower surface of the eaves girder 7 is 120 mm higher than the lower surface of the roof beam 12, so that the upper end of the sash 26 is close to the lower end of the eaves girder 7 on the first floor. By arranging in such a manner, an opening having a high height can be provided on the outer wall surface of the first floor, which is the lower floor of the hut 4, and the house 2 with a feeling of opening can be obtained. Moreover, since the Sei Ryo L ₁ of the pole plate 7 is larger, it is possible to bear a larger weighting, the width of the opening can be increased. FIG. 5B shows a lower floor opening in the conventional roof structure 1, and the lower surface of the eaves girder 7 ′ is lower than the lower surface of the eaves beam 7 according to the roof structure 1 of the present embodiment. Since it is low, the upper end of the opening is lowered.

Thus, the entire roof is raised by the large eaves girder 7 with the beam stake L ₁ , so that it is not necessary to use extra steps and parts such as installing auxiliary columns on the upper surface of the eaves girder 7. By the street process, it can be set as the hut assembly structure 1 which has the living space 3 of the hut back 4 with high ceiling height.

  Further, as described above, since the height of the upper surface of the eaves girder 7 is increased by 390 mm, the entire roof is increased by 390 mm, so that the living space 3 of the cabin back 4 is shown in FIG. As long as it is inside the area R that is 1.5 meters indoors from the eaves outer wall, a ceiling height of 2.1 meters or more should be secured no matter where the living space 3 is provided. Can do. Therefore, the room of the hut back 4 can be designed freely in the region R.

  Further, the wife side shed beam 12, that is, the upper surface of the timber beam is also provided at the same height as the upper surface of the other shed beam 12, so that it is lower than the floor surface 25 of the living space 3, and the shed on the wife side. The opening part opened from the floor 25 of the living space 3 of 4 can be provided, for example, a flat balcony can be provided in the outdoor side. That is, in order to increase the ceiling height of the living space 3 on the back of the hut 4, the upper surface of the eaves girder 7 is provided high, while the upper surface of the shed beam 12 is provided low, and the opening opened from the floor 25 to the wife side. Therefore, the air volume of the living space 3 of the shed 4 can be increased, and the living space 3 of the shed 4 having a large opening can be provided.

  Needless to say, the embodiment of the present invention is not limited to the above-described embodiment, and can be appropriately changed without departing from the scope of the idea of the present invention.

  The roof structure 1 and the house 2 according to the present invention can be suitably used mainly as the roof structure 1 and the house 2 of a one-story house.
