Description

  The present invention relates to a masonry building.

  Traditionally, masonry buildings have been used for building walls (structural walls) by stacking block materials such as bricks and concrete blocks. In Japan, where there are many earthquakes, It has been practiced to reinforce a material by providing a cavity and inserting a reinforcing bar into the cavity.

  Joint mortar is placed in the joint portion of the wall for joining the block materials. At this time, since the dried brick and concrete block have high water absorption, the moisture of the joint mortar may be absorbed and sufficient strength may not be obtained. For this reason, the work which wets a block material with water beforehand is required. Further, in order to prevent the joint mortar from being crushed by the weight of the block material, it is necessary to stack the block material after a certain time until the joint mortar is cured to some extent. In addition, it is necessary to place filling mortar in the hollow part of the block material into which the reinforcing bar is inserted in order to integrate the block material and the reinforcing bar. It is necessary to harden with.

  As such a masonry building, one described in Patent Document 1 is known. The masonry building described in Patent Literature 1 includes a wall body configured by placing concrete inside a formwork concrete block, and the girder is formed of concrete. Such a girder is formed by placing a formwork on the girder part and placing concrete. This masonry building is reinforced with steel columns and beams.

Japanese Patent Laid-Open No. 2004-316090

  In a conventional masonry building, the girder portion formed by placing concrete has a smooth finish, which is different from a masonry portion in which block materials such as concrete blocks are stacked. Therefore, there was a problem that it was not preferable in appearance design.

  This invention is made | formed in order to solve such a subject, and it aims at providing the masonry building which can improve the designability.

A masonry building according to the present invention is composed of a lower horizontal member, two vertical members erected above the lower horizontal member, and between the two vertical members on the lower horizontal member. It consists horizontal and vertical direction continuously provided a plurality of block material, a wall which encloses a longitudinal member by a plurality of block material, and an upper horizontal member which both ends are joined to the two longitudinal members of the top horizontal And a cover member fixed so as to be flush with the wall body only on the outside of the frame member, and the cover member is made of the same material as the block member.

  According to the masonry building according to the present invention, the cover material made of the same material as the block material is provided outside the upper horizontal member so as to be flush with the wall body. You can finish with the same texture. Further, since the vertical member is included in the plurality of block members, the appearance is not impaired by the exposure of the vertical member. Therefore, the designability can be improved.

Here, the cover material preferably has the same height as the block material, and the block material and the cover material are preferably arranged so that their vertical joints are staggered . According to this structure, since the height dimension of a cover material and the height dimension of a block material are arrange | equalized, the design property can be improved further.

  Further, the vertical member has a protruding piece continuous in the material axis direction, and at least one block material in contact with the vertical member is formed with a groove corresponding to the protruding piece at an end in the horizontal direction, and the protruding piece is formed in the groove. It is preferable that the two block members are fitted to each other with the vertical member interposed therebetween. According to this configuration, since the protruding piece of the vertical member is fitted into the groove of the block member, the block member can be arranged in a straight line along the vertical member, and the uprightness of the wall body is maintained. . Therefore, the designability can be improved more reliably.

  Further, the vertical member is disposed along the side end portion of one wall body at the protruding corner portion where the wall bodies are orthogonal to each other, and the side end portion of the one wall body is made of the same material as the block material. It is preferable that it is covered with a covering block material. According to this configuration, since the vertical member arranged at the protruding corner is covered and hidden by the covering block material made of the same material as the block material, the designability at the protruding corner can also be improved.

  According to the present invention, design properties can be improved.

However, in FIG. 3, in order to explain the configuration of the present embodiment, some of the block members are omitted and each component is shown in a separated state.

  As shown in FIGS. 1-3, the masonry building 1 is a two-story masonry house. The masonry building 1 is composed of a fabric foundation 2, a vertical member 5 erected above the fabric foundation 2, and a plurality of block members 3 continuously provided in the horizontal and vertical directions on the fabric foundation 2. A steel wall 6A between the first floor and the second floor, a steel bridge 6B between the second floor and the roof, a first floor 8A, a second floor 8B, and a roof floor 8C, It is configured with. The masonry building 1 is an industrialized house in which many of the members used are standardized and industrialized. The masonry building 1 has a planar module M (for example, M can be set to 455 mm). A plurality of the cores of the masonry building 1 are set at an interval that is an integral multiple of the plane module M in two orthogonal directions, and the thickness direction of the wall body 4 and the steel beams 6A and 6B (from the room to the outdoor room). The direction of the center line CL1 coincides with the core (see, for example, FIG. 2).

  The cloth foundation 2 is a reinforced concrete structure provided on the ground GD and functions as a foundation of the masonry building 1. The fabric foundation 2 has a portion embedded in the ground and a portion rising from the ground GD, and the upper end 2a of the rising portion is configured to be flat so that the first floor wall 4A is placed thereon. ing. The cloth foundation 2 is provided so as to extend in the horizontal direction along the core set in the masonry building 1, and is disposed immediately below the position where at least the first floor wall body 4A is provided. The cloth foundation 2 functions as a lower horizontal member for the first-floor wall body 4A.

The plurality of vertical members 5 are arranged apart from each other in the extending direction of the fabric foundation 2, the steel beam 6A, or the steel beam 6B. The center line of the vertical member 5 coincides with the core as described above. The vertical member 5 serves as a positioning reference when the plurality of block members 3 are stacked, and functions as a guide for the block member 3. Between the two vertical members 5 and 5 (see FIGS. 8 to 10), the block member 3 is stacked along the vertical members 5 and 5, and the block member 3 stacked along the vertical members 5 and 5 is used as a reference. By arranging the other block members 3, the accuracy of construction such as straightness and uprightness of the wall body 4 is ensured. Thus, the vertical member 5 has a function of improving workability and work accuracy. The vertical member 5 also has a function of reinforcing the wall body 4 in cooperation with the steel frame beams 6A, 6B and the like, suppressing deformation of the wall body 4 at the time of an earthquake, and improving earthquake resistance. However, since the load of the steel frame beams 6A and 6B and the block material 3 at the upper part of the steel beam beams 6A and 6B is transmitted directly to the lower block material 3 without passing through the vertical material 5, the vertical material 5 is generally used. It does not have a function of transmitting the vertical load of the pillar to the substructure.

The roof wall body 4C constitutes a parapet on the roof of the masonry building 1 and is provided above the steel frame beam 6B. The lower end 4b of the rooftop wall body 4C is placed and fixed on the steel frame beam 6B.

  The wall body 4 is constituted by a plurality of block members 3 which are connected in a horizontal direction and a vertical direction between the two vertical members 5 and 5 and joined to each other. The block members 3 adjacent in the horizontal direction and the vertical direction are joined together by an adhesive. Adjacent block members 3 are fixed by this adhesive. Even if it is thin application | coating, it is preferable to apply what has a sufficient adhesive effect and does not collapse when it receives compressive force. As the adhesive, for example, resin mortar can be applied. By using such an adhesive, it is not necessary to wait for the mortar to harden unlike the joint mortar used in the conventional masonry structure, and the labor of construction can be saved.

Not only the part that spreads out flat like the general part, but also the part where the shape changes irregularly, such as the corner of the wall, the corner of the wall, and the window frame part, etc., only the standardized block material (That is, without creating a block member having a special dimension for only a certain portion).

  For example, the wall body general part of the wall body 4 is configured by longitudinally stacking block materials 3A having a length dimension of 2M. That is, the wall body general portion of the wall body 4 is configured by stacking the block materials 3A in a staggered manner with a shift of M in length so that the upper surface 3e of the block material 3A stacked one step below can be seen. (See FIG. 3). In addition, a wall body general part is a part in which a wall body protrusion corner part, a wall body entrance corner part, and a window frame part are not formed like the area | region shown by B in FIG. 1, for example.

  Next, the arrangement of the vertical member 5 and the block member 3 will be described. FIG. 6A is a view of the arrangement of the block material in the wall body general portion as viewed from above, and FIG. 6B is a view of the arrangement of the block material in the wall body protruding corner portion as viewed from above. As shown in FIG. 6A and FIG. 6B, the longitudinal member 5 is composed of a longitudinal member 5P having a cross section of a long portion and a longitudinal member 5Q having a T portion of a cross section of the long portion. It consists of two types of steel. The vertical member 5P having a cross-shaped cross section has projecting pieces 50 and 50 that are continuous in the material axis direction and project in a direction perpendicular to the material axis direction. The vertical member 5Q having a T-shaped cross section has a protruding piece 51 that is continuous in the material axis direction and protrudes in a direction perpendicular to the material axis direction.

  As described above, the groove 3g or the groove 3h is formed in the block material 3A or the like. As shown to Fig.6 (a), a wall general part is comprised by connecting the block materials 3A and 3A continuously. The vertical member 5P is fitted in the groove 3g of one block member 3A and is fitted in the groove 3h of the other block member 3A. More specifically, the protruding piece 50 of the vertical member 5P is fitted in the deep groove 3k of the block member 3A. In other words, when the block members 3A are connected to each other, the groove 3g and the groove 3h form a cross-shaped space extending in the height direction of the block member 3A. The vertical member 5P is disposed in the cross-shaped space. The vertical member 5 </ b> P is sandwiched between the block members 3 </ b> A and 3 </ b> A and is included in the wall body 4. In this way, the vertical member 5P having a cross-shaped cross section can be used, for example, in the wall general portion.

  Moreover, as shown in FIG.6 (b), the wall body protrusion corner part is 3A of block materials, 3C of block materials orthogonal to the block material 3A, and the elongate shape affixed on the edge part of block material 3A. It is comprised with the block material 3G. The vertical member 5Q is fitted in the groove 3g of the block member 3A and is fitted in the shallow groove 3m of the block member 3G. More specifically, the protruding piece 51 of the vertical member 5Q is fitted into the deep groove 3k of the block member 3A. In other words, when the block material 3A and the block material 3G are connected in series, the groove 3g and the shallow groove 3m form a T-shaped space extending in the height direction of the block material 3A. The vertical member 5Q is disposed in the space having a T-shaped cross section. The vertical member 5Q is sandwiched between the block member 3A and the block member 3G and is included in the wall body 4. As described above, the vertical member 5Q having a T-shaped cross section can be used, for example, at a wall projecting corner.

  It can be set as appropriate to which part each vertical member 5P, 5Q is used. For example, a longitudinal member 5P having a cross-shaped cross section may be used for a corner portion or the like other than the general wall portion, or a vertical material 5Q having a T-shaped cross section may be used for the general wall portion. The vertical members 5P and 5Q may be used for any of the above-described first-floor wall body 4A, second-floor wall body 4B, and rooftop wall body 4C. In addition, the thickness of the block material is set larger than the cross-sectional dimension of the vertical member, or the corner block material is reinforced, so that the deep groove 3k is formed in the corner block material. If the above problem does not occur, a vertical member 5P having a cross-shaped cross section can be used at the corner.

  Next, the structure of the steel frame beams 6A and 6B will be described. As shown in FIGS. 2, 3, and 7, the steel frame beams 6 </ b> A and 6 </ b> B are laminated beams obtained by combining two channel steels.

As described above, the steel frame 6A is a dry upper horizontal member that is supported by the upper end 4a of the first-floor wall body 4A and whose both ends are joined to the two first-floor vertical members 5A and 5A.

  A cover member 21 is fixed to the outside of the steel frame beam 6A so as to be flush with the first floor wall body 4A and the second floor wall body 4B. The cover material 21 has a rectangular plate shape having the same height as the steel frame 6A, that is, the block material 3. The cover material 21 is made of the same material as the block material 3. The cover material 21 is fixed to a plate-like base material 22 arranged on the web of the steel bridge 6A with screws 23 or the like. The cover material 21 covers the steel beam 6A over the entire extending direction of the steel beam 6A, and its outer surface is exposed to the outside (see also FIG. 1). With this cover material 21, the entire wall surface of the building is finished with the same texture.

  A floor support member 24 for supporting the second floor 8B is fixed at a plurality of locations in the length direction (lateral direction) inside the steel beam 6A. The floor support member 24 protrudes toward the indoor side. Between the floor support member 24 and the lower end 4b of the second floor wall 4B, a long floor mounting plate 26 having a thickness equal to the flange portion of the steel frame 6A is fixed.

  The steel frame beam 6B disposed between the second-level wall body 4B and the roof wall body 4C has the same configuration as the steel frame beam 6A. In the same manner as the configuration around the steel bridge 6A described above, the cover member 21 and the like are provided outside the steel bridge 6B, and the floor support member 24 and the like are provided inside the steel bridge 6B. For the second floor wall 4B, the steel frame beam 6A functions as a lower horizontal member, and the steel frame beam 6B functions as an upper horizontal material. In addition, for the roof wall 4C, the steel frame 6B functions as a lower horizontal member.

  Next, the configuration of the floors 8A, 8B, 8C will be described. In the present embodiment, the floors 8A, 8B, 8C are each made of a panel material and are made dry. The first floor 8A is configured by arranging a plurality of panel materials. As the panel material, an ALC panel, a concrete panel, a wood panel, or the like can be applied. Each panel material of the first floor 8 </ b> A is supported by the fabric foundation 2 or a steel beam spanned over the fabric foundation 2.

The steel frame 6A is spanned over the upper ends of 5A and 5A. More specifically, the steel girder 6A is placed on the upper end 4a of the first floor wall 4A, and the first floor vertical member 5A is interposed via the gusset plates 20 fixed to both ends of the steel girder 6A. On the other hand, the steel frame 6A is bolted. Further, the longitudinal reinforcing steel bar 31 is inserted into the through hole of the steel frame beam 6A and fastened with a nut.

  Next, after providing the cover material 21, the floor support member 24, the floor mounting plate 26, etc., the second floor 8B is provided. Next, the second floor vertical members 5B and 5B are erected by bolting the base plate 5b (see FIG. 3) of the second floor vertical member 5B to the upper plate 5a of the first floor vertical member 5A. Next, the second-floor wall body 4B, the rooftop floor 8C, and the like are constructed in the same manner as the first floor between the steel frame 6A and between the second-floor vertical members 5B and 5B. Furthermore, the rooftop wall body 4C is configured in the same procedure as the first floor and the second floor.

  According to the masonry building 1 of the present embodiment described above, the cover material 21 made of the same material as the block material 3 is flush with the wall body 4 on the outside of the steel frame beams 6A and 6B. Because it is provided, the entire wall of the building is finished with the same texture. Moreover, since the vertical member 5 is enclosed by the plurality of block members 3, the appearance is not impaired by the exposure of the vertical member 5. Therefore, the designability is improved.

  Moreover, since the cover material 21 has the same height dimension as the block material 3, the height dimension of the cover material 21 and the height dimension of the block material 3 are aligned, and the design property is further improved. .

  Further, since the protruding pieces 50 and 51 of the vertical member 5 are fitted into the deep grooves 3k of the block member 3 and the two block members 3 and 3 are sandwiched between the vertical members, the blocks along the vertical member 5 are blocked. The materials 3 can be arranged in a straight line, and the uprightness of the wall body 4 is maintained. Therefore, the designability is more reliably improved.
