Description

The present invention relates to a structural slit member disposed along the side edge of a wall frame of a structure such as a building, and a method of constructing a wall frame adjacent to a column frame using the structural slit member.

As disclosed in Patent Documents 1 and 2, it is known that structural slits are provided for the purpose of cutting the edges between columns and beams and walls of reinforced concrete buildings, and the slits are used to cut the edges of the walls and columns of reinforced concrete buildings. It plays a role in preventing brittle fracture.

Structural slits were included as an earthquake-resistant design method in the 1981 Building Standards Act's New Earthquake Resistance Standards, and are widely used mainly in reinforced concrete condominiums. General structural slits are difficult to maintain and fix in shape only up to a certain height (for example, about 1.0m-1.5m) against the lateral pressure of the concrete, and a construction method that involves pouring concrete one after another on both sides of the structural slit is difficult. It has been adopted.

However, if the structural slit is improperly installed or the construction is not properly managed during concrete pouring, the structural slit may become bent or misaligned, which may require correction after construction.

Therefore, the present invention provides a structural slit member that can reduce the burden of construction management during concrete pouring and also prevent bending or misalignment of the structural slit, and a wall frame adjacent to a column frame using the structural slit member. The purpose is to provide a method for constructing.

In order to achieve the above object, a structural slit member of the present invention is a structural slit member for arranging a structural slit along a side edge of a wall body of a structure, the structural slit member being arranged at a side edge of the wall body. a strip-shaped structural slit; a truss portion formed in an elongated shape by a substrate and truss bars on the inside of the wall body along the structural slit; and an intermediate portion passed through a through hole of the structural slit. A fixing means for connecting the supporting member is provided.

Here, the fixing means is a fixing device disposed on an extension line of the through hole of the structural slit, and a plurality of the fixing devices are attached at intervals in the longitudinal direction of the truss part. be able to. Furthermore, the fixing device may be configured to be attached across the upper end reinforcement and the lower end reinforcement of the truss muscle. Further, the substrate may be a steel plate.

Further, the invention of a method for constructing a wall skeleton is a method for constructing a wall skeleton adjacent to a column skeleton using any of the structural slit members described above, wherein the structural slit member is placed at a position that is a boundary with the column skeleton. a step of connecting an intermediate support inserted from the column frame side to the fixing means; and a step of connecting the formwork of the wall frame in which the truss portion is arranged and reinforced. The method is characterized by comprising a step of continuously filling the inside with concrete up to the height of the wall structure.

Yet another invention of a method for constructing a wall frame is a method for constructing a wall frame adjacent to a column frame using any of the above-mentioned structural slit members, wherein the structural slit member is attached to the reinforcement of the column frame. a step of lifting the pillar unit and arranging it so that the structural slit member is located on the side edge of the wall body; and a step of continuously filling the inside of the formwork of the wall structure with concrete up to the height of the wall structure.

The structural slit member of the present invention configured as described above includes a truss portion formed in an elongated shape by the substrate and truss muscles arranged along the structural slit, and an intermediate support member passed through the through hole of the structural slit. and fixing means for connection.

In other words, the truss part added to increase the rigidity of the structural slit can be supported by an intermediate support member connected to the fixing means from the outside of the wall structure, and can also be supported by the wall structure that is later filled through the truss bars. Can be integrated with concrete.

For this reason, it can withstand large lateral pressures of concrete, and it is possible to place concrete at a higher height at once, thereby reducing the burden of construction management during concrete pouring. Furthermore, since the structural slit is supported by the highly rigid truss portion, it is possible to prevent bending or misalignment.

In particular, if multiple fixing devices are installed at intervals in the longitudinal direction of the truss, the structural slits placed on the side edges of the wall structure may be biased in the height direction. It can be supported without any need for support.

Furthermore, if the fixing device is installed across the top and bottom reinforcements of the truss, it is possible to prevent the fixing device from rotating around the top reinforcement, etc. Connection work becomes easier to carry out.

Furthermore, by using a highly rigid steel plate as the substrate of the truss part, deformation of the structural slit that is superimposed on the steel plate can be further suppressed, so that the effect of preventing the structural slit from bending or shifting can be enhanced.

In addition, in the invention of a method for constructing a wall skeleton, after arranging the structural slit members and connecting the intermediate support inserted from the column skeleton side to the fixing means, concrete is continuously poured up to the height of the wall skeleton. Fill.

In this way, by using a structural slit member in which the highly rigid truss part is supported by intermediate supports, the height of the wall structure can be built with one concrete pouring, so The burden of construction management can be reduced.

Furthermore, if a column unit with structural slit members is manufactured by arranging reinforcement in the column frame during ground assembly, etc., construction efficiency will be improved, making it possible to construct column frames and wall frames more efficiently. You will be able to do this.

Embodiments of the present invention will be described below with reference to the drawings.
FIG. 1 is a diagram illustrating a process of constructing a column frame 11 of a building 1 serving as a structure and a wall frame 12 adjacent thereto using the structural slit member 2 of this embodiment. Moreover, FIG. 2 is an explanatory diagram showing a schematic configuration of the wall frame 12 and column frame 11 of the building 1 in which the structural slit 3 is arranged.

Structural slits are placed at the boundaries between columns and walls, as shown in Figure 2, in order to prevent brittle fractures such as shear failures of columns and beams of buildings 1 such as buildings and apartment complexes when a large earthquake occurs. be done. The illustrated structural slit 3 is a member that cuts the edge between the column frame 11 and the wall frame 12, and is sometimes called a vertical slit, vertical slit, seismic slit, etc.

The structural slit 3 is arranged at the side edge 12 a of the wall frame 12 that forms the boundary with the column frame 11 . The wall body 12 is a frame body called a so-called miscellaneous wall, such as a wing wall, a waist wall, a hanging wall, etc., which is different from the main structural members. On the other hand, a structural slit arranged for the purpose of cutting the edge between the beam frame 13 and the wall frame 12 is called a horizontal slit 15 (see FIG. 2).

As shown in FIGS. 3 and 6, the structural slit member 2 of this embodiment includes a band-shaped structural slit 3, a truss portion 4 formed in an elongated shape along the structural slit 3, and a truss portion 4. It is equipped with a fixture 6 which serves as a fixing means to be attached to.

The structural slit 3 is a rectangular plate-shaped member made of a material such as styrofoam, urethane foam, polystyrene foam, or phenol foam. The structural slit 3 is formed in an elongated shape with a length comparable to the height of the wall skeleton 12.

As shown in FIG. 8, the structural slit 3 has a width narrower than the wall thickness (approximately 150 mm to 230 mm) of the wall body 12, and frame members 32 are attached to both edges of the wall body 12 in the wall thickness direction. It will be done. The edge of the structural slit 3 is fitted into one groove of the frame material 32, which has grooves formed on both sides, and a rectangular parallelepiped joint bar 33 fixed to the wall formwork 72 is fitted into the other groove. It will be done.

As shown in FIG. 8, a partition formed by the above-mentioned structural slit 3, frame material 32, and joint bar 33 is arranged at the boundary between the pair of wall forms 72, 72 and the column frame 11. The flow of concrete filled to construct the wall frame 12 and column frame 11 is dammed by this partition.

The truss portion 4 is formed in a long shape inside the wall frame 12 along the longitudinal direction (vertical direction) of the structural slit 3 . The truss section 4 of this embodiment is formed of a substrate 41 and a truss muscle 42, as shown in FIG.

The substrate 41 is a band-shaped member that is brought into close contact with one surface of the structural slit 3, and is formed of a deck plate, a corrugated plate, or the like. The substrate 41 has a width and length comparable to the width and length of the structural slit 3, and is connected to the truss part 4 by bonding the substrate 41 to one surface of the structural slit 3 with adhesive, screws, double-sided tape, etc. The structural slit 3 can be treated as one unit.

On the other hand, the truss muscle 42 is formed into an isosceles triangular shape in plan view by an upper end reinforcement 421, a lower end reinforcement 422, and a wave-shaped lattice reinforcement 423 that connects them (see FIG. 8). The truss muscle 42 has various forms, and the upper end reinforcement 421 is placed near the apex of the isosceles triangle, but the position of the lower end reinforcement 422 and the shape of the lattice muscle 423 may vary. Things can be used.

In short, the truss section 4 is formed into a highly rigid elongated member by a substrate 41 and a truss muscle 42 whose base portion of an isosceles triangle in plan view (see FIG. 8) is joined to one surface of the substrate 41. Bye. For example, the truss section 4 made of a substrate 41 made of a thin galvanized steel plate and truss bars 42 made of a combination of small-diameter reinforcing bars (421, 422, 423) has high rigidity and is lightweight. Therefore, it is easy to handle.

Here, as shown in FIG. 8, one wall surface of the wall frame 12 is defined as a first wall surface 121, and the other wall surface facing it is defined as a second wall surface 122. The truss portion 4 is arranged inside the wall frame 12 between the first wall surface 121 and the second wall surface 122. The truss portion 4 and the wall skeleton 12 are integrated by filling the periphery of the truss reinforcement 42 with concrete poured on-site to form the wall skeleton 12.

Further, as shown in FIG. 3, a fixture 6 is attached to the truss portion 4, which serves as a means for fixing the intermediate support member 61. As shown in FIG. 6, a through hole 31 is bored at a position of the structural slit 3 and the substrate 41 facing the fixture 6. That is, the fixture 6 of the intermediate support member 61 is arranged on the extension line of the structural slit 3 and the through hole 31 of the substrate 41.

FIG. 4 is a perspective view illustrating an example of the configuration of the fixture 6. This fixture 6 is provided with two clamping parts 62 through which the upper end reinforcement 421 and the lower end reinforcement 422 of the truss reinforcement 42 are passed. As shown in FIG. 3, the upper end reinforcement 421 and the lower end reinforcement 422 are passed through the inner space of the holding portion 62 which is U-shaped in plan view.

On the open side of the holding portion 62, a stopper 621 is formed of a resin material such as rubber to allow the upper end reinforcement 421 and the lower end reinforcement 422 to be fitted and to prevent them from coming off or shifting.

A hanging piece 63 is extended from each of the two holding parts 62, and an intermediate support member is installed in the space between the arched ceiling formed by the hanging piece 63 and the fixing screw 64 spanned below. 61 is inserted.

The fixing screw 64 has one end fixed to the clamping part 62 and the other end protruding from the hanging piece 63, and is inserted by tightening the nut 641 screwed into the protruding end of the fixing screw 64. The intermediate support 61 can be fixed.

As shown in FIG. 3, the fixture 6 is attached across the upper end reinforcement 421 and the lower end reinforcement 422 of the truss reinforcement 42, so that it can be prevented from rotating around the upper end reinforcement 421 and the lower end reinforcement 422. Further, the intermediate support member 61 passed through the two hanging pieces 63 is horizontally extended toward the inside of the wall frame 12.

The fixture 6 serving as the fixing means is not limited to the form shown in FIG. 4, and FIG. 5 shows the configuration of another fixture 6A. The fixture 6A shown in FIG. 5 has the same holding part 62 and stopper 621 as the fixture 6 shown in FIG. 4, but differs in the way the intermediate support member 61 is connected.

An overhanging piece 65 is extended from the two holding parts 62 of the fixture 6A so as to be parallel to the substrate 41, and the intermediate support member 61 is inserted into the hole of the overhanging piece 65. A fixing nut 66 is placed in the hole of the overhanging piece 65, and by tightening the fixing nut 66, the inserted intermediate support member 61 can be fixed. The intermediate support member 61 supported by the two overhang pieces 65 is horizontally extended toward the inside of the wall frame 12 .

As can be seen from the position of the intermediate support member 61 shown in FIG. 6, a plurality of fixtures 6 are attached at intervals in the longitudinal direction of the truss portion 4. For example, the fixtures 6 are attached to the truss portion 4 at intervals of about 200 mm to 400 mm in the vertical direction.

An end of an intermediate support member 61 inserted from the column frame body 11 side is connected to the fixture 6, and the structural slit member 2 can be supported by this intermediate support member 61. The intermediate support member 61 can be formed of a bar-shaped material such as a reinforcing bar, a separator, or a full screw. Further, the intermediate support member 61 is not limited to being formed from one rod-shaped material, but may be formed by combining a plurality of rod-shaped materials, such as having a joint in the middle.

It is preferable that the fixtures 6 are arranged closer together in the lower part of the structural slit member 2 where the lateral pressure of the concrete is greater than in the upper part. For example, FIG. 6 shows an example in which the lower part of the structural slit member 2 has an arrangement interval of 200 mm, and the arrangement interval from the middle part to the upper part is 400 mm.

The structural slit member 2 of this embodiment is connected to the column frame 11 by the intermediate support member 61 passed through the fixture 6. In the conventional earthquake-resistant structure with structural slits, it was necessary to place steady rest bars to prevent the walls that border the columns from falling over, but the wall frame 12 is connected to the column frame 11 through the intermediate support 61. By using the structural slit member 2 of this embodiment, the intermediate support member 61 can have the function of a steady rest.

Next, a method of constructing the wall frame 12 adjacent to the column frame 11 using the structural slit member 2 of this embodiment will be described. In this embodiment, a case will be described in which a wall frame 12 is constructed adjacent to a column frame 11, as shown in FIG. 1 or FIG.

In the column reinforcement 111 of the column frame 11, band reinforcing bars serving as shear reinforcing bars are arranged so as to surround the outside of the main reinforcing bars extending in the vertical direction. In addition, intermediate band reinforcing bars serving as shear reinforcing bars are spanned so as to partition the inner space of the band reinforcing bars, which are approximately rectangular in plan view (see FIGS. 1 and 7).

Before installing the structural slit member 2 in a predetermined position, a wall formwork 72 forming one wall surface of the wall frame 12 is assembled. For example, the wall formwork 72 in the upper part of the drawing, which is continuous with the column formwork 71 shown in FIG. 1, is installed first. The formwork (71, 72) is formed by shoring 7, sheathing boards, separators 52, etc., which are assembled using single pipes, crosspieces, and the like.

Then, the column reinforcement 111 is assembled inside the column form 71, and the wall reinforcement 123 is assembled inside the wall form 72. Furthermore, structural slit members 2 are installed on both side edges of the wall reinforcement 123.

Here, there are two methods for arranging the structural slit member 2. The first method is to first arrange the structural slit member 2 at a position that will be the boundary with the column frame 11, and then assemble the wall reinforcement 123.

A second method is to assemble the column unit 20 as shown in FIG. 7 by assembling the column. For example, the column reinforcement 111 is assembled in a work yard. The column reinforcement 111 can be assembled efficiently if the ground assembly can be constructed in a large space such as a work yard.

Then, structural slit members 2 are attached to the positions of the column reinforcements 111 assembled into the ground and at the boundaries with the wall body 12, respectively. The column unit 20 manufactured in this way (the structural slit member 2 in the case of the first method described above) is lifted up by a hoist, crane, etc., and installed at a predetermined position. The structural slit member 2 whose rigidity is increased by the truss part 4 is lightweight, so there is little increase in weight even when it is attached to the column reinforcement 111, and it is lifted and installed together with the column reinforcement 111 as a column unit 20 with a crane or the like. be able to.

The wall reinforcement 123 is placed through the horizontal slit 15 on the floor surface formed on the beam frame 13 of the lower floor. That is, the wall frame 12 and the floor surface are separated by the horizontal slit 15 (see FIG. 2).

As shown in FIG. 1, the structural slit member 2 placed at the boundary with the column frame 11 is inserted from the column reinforcement 111 side through the through hole 31 (see FIG. 6) to the wall frame 12 side. One end of the intermediate support member 61 that protrudes is connected to the fixture 6.

In the building 1 shown in FIG. 1, the other end of the intermediate support member 61 is also connected to the fixture 6 of the structural slit member 2 for the wall frame 12 constructed on the opposite side with the column frame 11 in between. In short, the interval between the structural slit members 2, 2 on both sides of the column frame 11 is maintained by the intermediate support member 61.

On the other hand, in the building 1A shown in FIG. 9, the wall frame 12 is provided only in one direction with respect to the column frame 11, so the other end of the intermediate support member 61, whose one end is connected to the fixture 6, is connected to the column frame 11. It will be fixed to the shoring 7 that supports the frame 71.

After the column reinforcement 111 and wall reinforcement 123 are assembled in this way, the remaining column forms 71 and wall forms 72 are installed. Here, the wall forms 72, 72 are connected by a separator 52, as shown in FIGS. 1 and 9. In this way, it is ready to be filled with cast-in-place concrete.

Here, with reference to FIG. 10, the order of placing concrete for columns, walls, and beams in the conventional building a1 will be explained. In this building a1, a structural slit a2 is interposed between the pillar and the walls on both sides.

First, concrete is poured at the bottom of the column. Since concrete is a fluid when filled, a lateral pressure corresponding to the pouring height acts on the structural slit a2, as illustrated as a partial image in the center of the left wall in FIG. 10.

Since the structural slit a2 itself is a plate material with low rigidity formed from polystyrene foam or the like, there is a possibility that it will bend or shift if large lateral pressure from concrete is applied to it. Therefore, first, concrete is poured to about 1/3 of the height of the pillar.

Next, fill the lower parts of the walls on the left and right sides of the pillars with concrete to the same height. Concrete is then placed between the columns and the left and right walls, and then concrete is placed at the tops of the columns and the left and right walls. The final step is to pour concrete for the beams, and the concrete pouring process involves 10 steps.

In contrast, the structural slit member 2 of this embodiment includes a highly rigid truss section 4, and the truss section 4 is supported by an intermediate support member 61 connected from the column frame 11 side. .

The intermediate support member 61 will be inserted into the through hole 31 shown in FIG. The structural slit member 2 can be supported.

Therefore, as shown in FIG. 2, the concrete for the column frame 11 can be continuously poured at one time up to about 2.5 m. Further, the wall bodies 12 on the left and right sides of the column body 11 can also be continuously filled with concrete up to the height of the wall body 12.

Finally, concrete for the beam frame 13 will be placed, and the concrete placing process will only require four steps. In short, compared to the conventional concrete pouring process, six steps can be reduced.

Next, the effects of the structural slit member 2 of this embodiment and the method of constructing the wall frame 12 adjacent to the column frame 11 using the structural slit member 2 will be described.

The structural slit member 2 of this embodiment configured in this way has a truss portion 4 formed in an elongated shape by a substrate 41 and a truss muscle 42 arranged along the structural slit 3, and A fixing member 6 for an intermediate support member 61 is provided on an extension line of the hole 31.

That is, the truss portion 4 added to the structural slit 3 to increase rigidity can be supported by the intermediate support member 61 connected to the fixture 6 from the outside of the wall skeleton 12, and can also be supported laterally via the truss muscle 42. It can be integrated with the concrete of the wall frame 12 that is filled with the concrete.

If concrete can withstand large lateral pressure in this way, it will be possible to continuously pour concrete to a height exceeding 1.5m at a time, reducing the burden of construction management during concrete pouring. be able to reduce it.

Further, since the structural slit 3 is supported by the highly rigid truss portion 4, bending or displacement can be prevented. In particular, if a plurality of fixing devices 6 of the intermediate support member 61 are attached at intervals in the longitudinal direction of the truss portion 4, the structural slit 3 disposed on the side edge 12a of the wall skeleton 12 can be fixed in the height direction. can be supported without bias.

Furthermore, if the fixture 6 is installed across the upper end reinforcement 421 and the lower end reinforcement 422 of the truss reinforcement 42, it is possible to prevent the fixture 6 from rotating around the upper end reinforcement 421 or the like. Therefore, the work of connecting the intermediate support member 61 becomes easier.

In addition, in the method for constructing a wall frame according to the present embodiment, after arranging the lightweight and easy-to-handle structural slit member 2 and connecting the end of the intermediate support member 61 inserted from the column frame 11 side to the fixture 6, , the concrete is continuously filled up to the height of the wall frame 12.

In this way, by using the structural slit member 2 in which the lightweight and highly rigid truss part 4 is supported by the intermediate support member 61, the height of the wall frame 12 can be constructed with one concrete pouring. , it is possible to reduce the burden of construction management during concrete pouring.

Furthermore, if the column unit 20 to which the structural slit member 2 is attached is manufactured by reinforcing the column frame 11 during ground assembly or the like, the workability is improved compared to working in a narrow space with formwork close together. Therefore, the column frame 11 and wall frame 12 can be constructed more efficiently.

Hereinafter, structural slit members 2A and 2B of an embodiment other than the structural slit member 2 of the embodiment described above will be described with reference to FIGS. 11 and 12. Note that parts that are the same or equivalent to those described in the above embodiment will be described using the same terms or the same symbols.

FIG. 11 is an enlarged perspective view illustrating the configuration of the structural slit member 2A of the first embodiment. The first structural slit member 2A of Example 1 includes a band-shaped structural slit 3, a truss portion 4A formed in a long shape along the structural slit 3, and a fixture 6 attached to the truss portion 4A. It is equipped with Here, the fixture 6 serving as a means for fixing the intermediate support member 61 may be the fixture 6A (see FIG. 5) described in the previous embodiment.

The truss portion 4A of the structural slit member 2A is formed of a steel plate 43 serving as a substrate and a truss bar 42. The steel plate 43 is a strip-shaped steel material that is brought into close contact with one surface of the structural slit 3, and its rigidity can be adjusted according to its thickness.

The width and length of the steel plate 43 are comparable to the width and length of the structural slit 3, and the frame members 32 are fitted into the edges on both sides of the overlapping structural slit 3 and the steel plate 43, respectively. The structural slit 3 and the steel plate 43 can also be joined using adhesive, screws, double-sided tape, or the like. Then, the truss reinforcement 42 is joined to the surface of the steel plate 43 exposed on the wall frame 12 side.

On the other hand, FIG. 12 is an enlarged perspective view illustrating the configuration of another structural slit member 2B of the first embodiment. The second structural slit member 2B of Example 1 includes a band-shaped structural slit 3, a truss portion 4B formed in a long shape along the structural slit 3, and a fixture 6A attached to the truss portion 4B. It is equipped with Here, the fixture 6A serving as a means for fixing the intermediate support member 61 may be the fixture 6 (see FIG. 4) described in the above embodiment.

The truss portion 4B of the structural slit member 2B is formed by a steel plate 44 serving as a substrate and a truss bar 42. The steel plate 44 is a strip-shaped steel material that is brought into close contact with one surface of the structural slit 3, and its rigidity can be adjusted according to its thickness.

The length of the steel plate 44 is approximately the same as the length of the structural slit 3, but the width is narrower than the width of the structural slit 3, and has a width that fits between the frame members 32, 32 fitted on both ends of the structural slit 3. It is formed.

By bonding the overlapping steel plate 44 to one surface of the structural slit 3 using adhesive, screws, double-sided tape, or the like, the truss portion 4B and the structural slit 3 can be handled as one unit. Then, the truss reinforcement 42 is joined to the surface of the steel plate 44 exposed on the wall frame 12 side.

In the structural slit members 2A and 2B of the first embodiment configured as described above, the substrates of the truss part 4 are made of highly rigid steel plates 43 and 44, so that the structural slit 3 overlapped with the steel plates 43 and 44 can be prevented from deformation. Since this can be further suppressed, the effect of preventing the structural slit 3 from bending or shifting can be enhanced.

Note that other configurations and effects are substantially the same as those of the embodiment described above, so explanations thereof will be omitted.

The embodiments and examples of the present invention have been described above in detail with reference to the drawings, but the specific configuration is not limited to these embodiments or examples, and may be modified without departing from the gist of the present invention. Modifications in design are included in the invention.
