Description

  The present invention relates to a non-structural wall such as a vertical wall or a sleeve wall, and more specifically to a non-structural non-structural wall that does not use concrete and a method for constructing the same.

  In a reinforced concrete building structure, a non-structural wall (or a non-bearing wall) such as a vertical wall or a sleeve wall may be constructed for the purpose of ensuring comfort and partitioning the space. This non-structural wall is composed of rebar and concrete, but as its name suggests, it is not a structure that actively resists external forces during an earthquake.

  However, external forces during earthquakes also act on unstructured walls. If a load exceeding the proof strength of the non-structural wall is applied, the concrete will crack, resulting in a significant loss of appearance as a living space. The tensile strength of general concrete is about 1/10 of the compressive strength, and once a tensile force is applied, cracking occurs relatively easily.

  FIG. 10 is a model diagram for explaining that oblique tension cracking occurs when an external force is applied to a conventional vertical wall. The structure in this figure is a ramen structure in which an upper beam BU and a lower beam BL are provided between a left column PL and a right column PR, and a vertical wall is constructed between the upper beam BU and the lower beam BL. When an external force during an earthquake acts on such a ramen structure, the external force during an earthquake also acts on a vertical wall restrained by the upper beam BU and the lower beam BL. In this case, the vertical wall that should be a non-structural wall forms a compression bundle associated with the arch mechanism (the so-called tension mechanism), and as a result of trying to resist the external force at the time of the earthquake, the oblique tension cracking occurs.

  Although the cracks in the non-structural wall have little structural influence on the building structure itself, as described above, the appearance of the living space is significantly impaired. Conventionally, the crack of the non-structural wall has been regarded as a problem, and various improvement techniques have been proposed so far. For example, Patent Document 1 proposes a technique in which a reinforcing material is additionally disposed on a reinforcing bar of a concrete non-structural wall. Specifically, in addition to normal reinforcement (so-called vertical and horizontal bars), a reinforcing material is arranged in an X shape, and this reinforcing material is fixed to a member such as an upper beam or a lower beam.

JP 2013-147905 A

  The technique proposed in Patent Document 1 can expect seismic strength despite the fact that it is an unstructured wall, because the reinforcing material arranged in an X-shape works effectively against the earthquake load. It is a technology that has the effect of being able to. However, it is not a technology that can solve the problem of suppressing cracks in concrete.

  As described above, since the tensile strength is extremely small compared to the compressive strength, the concrete is very easily cracked. Furthermore, when a wall-like concrete structure is used, the moment of inertia of the cross section increases, and accordingly, the bending rigidity represented by the product of the cross section of the secondary moment and the elastic modulus also increases, and as a result, a large load is borne. become. Usually, a concrete wall has a thin member thickness and a small tensile strength, so that a crack is easily generated when a large load is applied. Such a crack generation mechanism cannot be prevented by a reinforcing material arranged in an X shape. For example, even if an X-shaped reinforcing material is arranged in the structure of FIG. 10, a large compressive force acts on the concrete having the arch mechanism, and a crack is generated in a direction perpendicular to the compressive force direction.

  The object of the present invention is to solve the problems of the prior art, that is, non-concrete non-structure that does not cause cracking even when external force acts during an earthquake, that is, does not impair the appearance. It is to provide a wall and a method for constructing this unstructured wall.

  The present invention has been made by paying attention to the point that the non-structural wall is made of non-concrete, and that the wall member constituting the non-structural wall uses a material having a smaller elastic modulus than concrete. It was based on an unprecedented idea.

  The non-concrete non-structural wall of the present invention is a non-concrete non-structural wall provided with structural bars and plate-like wall members. This wall member is formed of a material different from concrete and having a smaller elastic modulus than concrete. The structural bar is composed of a rod-like or plate-like shaft member, and the two shaft members intersect each other. And it has the structure where the structural reinforcement was built in the wall member.

  The non-structural non-structural wall of the present invention may include a wall member having a smaller strength difference than the compressive strength and tensile strength difference of the concrete.

  The non-concrete non-structural wall of the present invention may be provided with a wall member formed of a wooden material or a laminated material of a wood veneer.

  The non-structural wall construction method of the present invention includes a wall member formed of two plate members made of a material different from concrete and having a smaller elastic coefficient than concrete, and two rod-like or plate-like shaft members. Is a method of installing a non-concrete non-structural wall having structural bars crossing each other on a structure, and includes a fixing tool installation process, a structural reinforcement installation process, and a wall body installation process. In the fixing tool installation process, the fixing tool is installed in the structure, and in the structural reinforcement installation process, the structural reinforcement is installed by fixing the shaft member to the fixing tool. In the wall body installation step, the two wall members constituting the wall member are arranged and fixed so as to sandwich the structural reinforcement, thereby constructing a “wall body” composed of the structural reinforcement and the wall member. Note that one or both plate members constituting the wall member are provided with a housing groove for housing the structural reinforcement.

  In the non-structural wall construction method of the present invention, in the structural reinforcement installation step, the structural member is fixed by fixing the shaft member to which the first plate member is attached among the two plate members constituting the wall member to the fixing tool. It can also be set as the method of installing. In this case, in the wall body installation step, the wall member is constructed by fixing the second plate member constituting the wall member to the first plate member so as to sandwich the structural reinforcement.

  The non-structural wall construction method of the present invention may be a method of installing a wall body in which a wall member and a structural bar are integrated so as to incorporate a structural bar. In this case, in the wall body installation step, the structural bars partially protruding from the wall member are fixed to the fixing tool.

  The non-structural wall construction method of the present invention can be a method further comprising a stuffing step. In this case, the non-structural wall is disposed between the upper beam and the lower beam so that a gap is provided between the upper beam and the wall member and between the lower beam and the wall member. In the space filling step, the space between the upper beam and the wall member and the space between the lower beam and the wall member are filled with the space filling material.

The non-concrete non-structural wall and the non-structural wall construction method of the present invention have the following effects.
(1) It is a structure provided with energy absorption capability higher than that of a conventional non-structural wall by arranging structural bars in which two shaft members intersect each other.
(2) Since the wall member covering the structural reinforcement has a smaller elastic coefficient than concrete, it does not bear a load as compared with a conventional non-structural wall made of concrete, so that the occurrence of cracks and damage can be significantly suppressed.
(3) Since the structural reinforcement is buckled and reinforced by the wall member, it can effectively resist the compressive force in addition to the tensile force.
(4) By making the wall member a wooden material (or a laminated material of woody single plates), it is possible to provide an excellent appearance as a living space.
(5) Since the yield strength and fracture strength of the structural reinforcement can be clearly grasped and designed easily, the structural reinforcement can be positively employed as an earthquake-resistant member when planning.

  An example of an embodiment of a non-structural wall and a non-structural wall construction method of the present invention will be described with reference to the drawings.

1. FIG. 1 is a front view showing a non-structural wall 100 of the present invention, in which (a) shows a non-structural wall 100 as a vertical wall, and (b) shows a non-structural wall 100 as a sleeve wall. . As shown in this figure, the non-structural wall 100 of the present invention is composed of a wall member 110 and a structural bar 120, and the wall member 110 is composed of two plate members. It consists of two shaft members 121 having an extremely long length, and a reinforcing bar, a steel plate or the like is used. For example, the non-structural wall 100 of the present invention is constructed between the upper beam BU and the lower beam BL provided between the existing left column PL and right column PR. In this figure, for the sake of convenience, the structural reinforcement 120 is drawn so that it can be seen. However, the structural reinforcement 120 is actually built in the wall member 110.

  FIG. 2 is a flowchart showing the flow of main steps of the present invention. The overall outline of the present invention will be described with reference to this flowchart. First, a fixing tool for fixing the structural muscle 120 is installed on a structure (for example, a beam) (Step 10). As described above, the structural bar 120 is composed of the shaft member 121, and the fixing member such as a hole anchor fixes the shaft member 121. When the fixing tool is installed, the structural muscle 120 is fixed to the fixing tool (Step 20). Then, the two plate members 111 are arranged so as to sandwich the structural reinforcement 120 from both sides (front and back), and the wall member 110 is formed by bonding (or joining) these plate members 111. As a result, the wall member is formed. A “wall” composed of 110 and the structural muscle 120 is constructed (Step 30). 3A and 3B are explanatory views showing two plate members 111 arranged so as to sandwich the structural reinforcement 120 from both sides. FIG. 3A is a front view showing each component before arrangement, and FIG. It is a side view which shows the condition which arrange | positions.

  As described above, instead of the method of carrying the wall member 110 and the structural reinforcement 120 as separate members and installing them separately, the “ready-made wall” in which the wall member 110 and the structural reinforcement 120 are integrated in advance is carried in. It is also possible to adopt the method of installing as it is. In this case, first, a wall body is manufactured at a factory or the like (Step 40), and the ready-made wall body is carried into a construction site and installed at a predetermined position (Step 50).

  When the wall body installation step (Step 30) or the ready-made wall body installation step (Step 50) is completed, the final thinning is performed (Step 60). For example, when a wall is installed between the existing upper beam BU and the lower beam BL, a gap may be provided vertically (that is, between the wall and the upper and lower beams). Filling this gap with a filling material such as concrete or mortar is the filling process (Step 60).

  Hereinafter, each main element constituting the non-structural wall and the non-structural wall construction method of the present invention will be described in detail.

2. Non-structural wall (wall member)
As described above, the wall member 110 is constituted by the two plate members 111. The plate member 111 is made of a material that is not made of concrete, such as a wood board or a plywood (a laminated material of wood single plates). In addition to the wooden plate material 111 such as a wooden plate or a plywood, a plate made of FRP (Fiber Reinforced Plastics), a glass plate, a gypsum board, a synthetic resin plate, or the like can be used as the plate member 111. However, the plate member 111 is formed of a material having an elastic coefficient smaller than that of concrete.

  The concrete wall has a second moment of inertia Ic that increases in proportion to the cube of the length of the wall. Along with this, the bending rigidity represented by the product of the cross-sectional secondary moment Ic and the elastic modulus Ec also increases, and as a result, the concrete wall bears a large load, causing cracks and the like. Therefore, in the present invention, the plate material 111 made of a material having a bending rigidity smaller than that of the concrete wall is used. The plate material 111 having a bending rigidity smaller than that of the concrete wall has a smaller load load than that of the concrete wall, and deformation such as cracks is less likely to occur.

  In order to make the bending rigidity smaller than that of the concrete wall, either the cross-sectional secondary moment I or the elastic modulus E may be made small. Regarding the cross-sectional shape, since there are various conditions for each site where the non-structural wall 100 is constructed, it may be difficult to reduce the cross-sectional secondary moment I. Therefore, in the present invention, the elastic modulus E is reduced. Here, the elastic modulus refers to a static elastic modulus obtained from a stress-strain curve due to static loading.

  Moreover, concrete has a characteristic that the tensile strength is remarkably smaller than the compressive strength (about 1/10), and cracking easily occurs when a tensile force is applied. Therefore, it is also effective that the plate member 111 of the present invention is made of a material in which the difference between the tensile strength and the compressive strength (hereinafter referred to as “strength difference”) is smaller than that of the concrete. If the material is not much different from concrete in compressive strength, the tensile strength is greater than that of concrete, and the plate member 111 is less likely to be cracked regardless of which compressive force or tensile force is applied. Furthermore, if the plate member 111 is made of a material having a specific gravity smaller than that of concrete, the workability is improved, and an earthquake load that increases in accordance with its own weight is reduced.

(Structural muscle)
As described above, the structural reinforcement 120 is constituted by the two shaft members 121. As a result of reducing the bending rigidity of the wall member 110 (plate material 111), the load load is reduced, and the structural reinforcement 120 necessarily bears a large load. Therefore, the shaft member 121 is made of a steel material having a large tensile strength and compressive strength, for example, a reinforcing bar, a narrow flat bar, or an angle steel. Of course, as long as the shaft member 121 is a material having both high tensile strength and compressive strength, not only steel but also other materials can be used.

  The two shaft members 121 are arranged so as to cross each other. Specifically, two shaft members 121 are placed in substantially the same plane (for example, a vertical plane), and are arranged in an X shape. And the structural reinforcement 120 which consists of these two shaft members 121 is arrange | positioned so that it may be pinched | interposed into the two board members 111 from the front and back. The two plate members 111 are bonded and fixed by applying an adhesive, or bonded and fixed by screws or bolts, or integrated by various methods. On the other hand, the structural reinforcement 120 and the plate member 111 can be fixed by bonding or the like, or need not be subjected to special fixing processing. Since the structural reinforcement 120 is buckled and stiffened by being sandwiched between the two plate members 111, in addition to the function as a tensile material, it can also function as a compression material that absorbs energy by axial yielding. Note that both ends of the two shaft members 121 are fixed to a structural member such as a new (or existing) beam.

3. Non-structural wall construction method The method of constructing the non-structural wall 100 of the present invention into a concrete beam or the like can be broadly classified into three, and further divided into four examples including the case of a steel beam. A structural wall construction method will be described.

(First example)
The first example is a method for constructing the non-structural wall 100 according to the present invention between a concrete upper beam BU and a concrete lower beam BL. The wall member 110 and the structural bar 120 are separated from each other. It is a method of carrying in as a member and installing each separately.

  First, the fixing device installation step (Step 10: FIG. 2) and the structural reinforcement installation step (Step 20: FIG. 2) will be described. FIG. 4 is an explanatory view showing a procedure for fixing the shaft member 121 divided into two vertically to the fixing device 130 installed on the upper beam BU and the lower beam BL, and (a) is a divided upper portion of the first shaft member. 121B shows a state where 121U is fixed to the fixing tool 130, (b) shows a state where the divided lower part 121L of the first shaft member is fixed to the fixing tool 130, and (c) shows a divided upper part 121U of the first shaft member. The state which connected the division | segmentation lower part 121L is shown, (d) shows the state in which the 1st shaft member 121 and the 2nd shaft member 121 were installed.

  As shown in FIG. 4, the shaft member 121 is divided into an upper part and a lower part, and is fixed separately. For convenience, one of the divided shaft members 121 is referred to as a divided upper portion 121U and the other is referred to as a divided lower portion 121L. First, “post-installed anchors” such as hole anchors are embedded and installed as fixing tools 130 at two locations of the upper beam BU and two locations of the lower beam BL. Then, as shown in FIG. 4A, the divided upper part 121U of the first shaft member 121 is fixed to the fixing tool 130 of the upper beam BU. At this time, if a part of the divided upper part 121U is threaded and the fixing device 130 is also threaded, it can be easily connected and fixed.

  When the divided upper portion 121U of the first shaft member 121 is fixed, as shown in FIG. 4B, the divided lower portion 121L of the first shaft member 121 is fixed to the fixing tool 130 of the lower beam BL. And as shown in FIG.4 (c), the connection tool 122 (for example, coupler) attached to the end of the division | segmentation upper part 121U is moved below, and the division | segmentation upper part 121U and the division | segmentation lower part 121L are connected. Also in this case, if a part of the divided upper part 121U and the divided lower part 121L are processed with screws and the connector 122 is also processed with screws, it can be easily connected and fixed. Moreover, when a shaft member is a reinforcing bar, a commercially available reinforcing bar joint can also be used. When the first shaft member 121 can be installed, the second shaft member 121 is installed in the same procedure, and the structural bar 120 is installed on the structure. In addition, as shown in FIG.4 (d), the arrangement position of the coupling tool 122 shall be the position away from the position where both the 1st shaft member 121 and the 2nd shaft member 121 cross | intersect.

  Incidentally, as a method of fixing the shaft member 121 to the fixing tool 130, the method shown in FIG. 5 can be adopted in addition to the method shown in FIG. FIG. 5 is an explanatory view showing a procedure for fixing the shaft member 121 to the tip muscle 121A fixed to the fixing tool 130 in advance, and (a) shows a state in which the tip muscle 121A is fixed to the fixing tool 130. (B) shows a state in which the first shaft member 121 is disposed near the tip muscle 121A, and (c) shows a state in which the first shaft member 121 and the tip muscle 121A are connected.

  FIG. 4 shows an example in which the divided upper part 121U (the divided lower part 121L) of the shaft member 121 carried in is fixed after the fixing tool 130 is embedded and installed. On the other hand, in FIG. 5, the tip muscle 121 </ b> A is fixed at the same time that the fixing tool 130 is embedded and installed. At this time, if a part of the tip muscle 121A and the fixing tool 130 are threaded, they can be easily connected and fixed. Then, the carried shaft member 121 and the tip muscle 121A are connected. Specifically, the connecting member 122 attached to one end of the shaft member 121 is moved upward to connect the shaft member 121 and the tip muscle 121A. Also in this case, if the shaft member 121 and a part of the tip muscle 121A are threaded and the connector 122 is also threaded, it can be easily connected and fixed.

  If the shaft member 121 can be installed on the upper beam BU and the lower beam BL, then the wall member 110 is constructed. FIG. 6 is an explanatory view showing a procedure for constructing the wall member 110 which is a separate member from the structural reinforcement 120, (a) shows a state in which the shaft member 121 is installed on the upper beam BU and the lower beam BL, (B) shows the state which arrange | positions the back plate member 111, (c) shows the state which arrange | positions the front plate member 111, (d) shows the state which filled the padding material 140. FIG.

  As shown in FIG. 6, with the shaft member 121 installed on the upper beam BU and the lower beam BL, the back plate member 111 of the two plate members 111 constituting the wall member 110 is arranged at a predetermined position. To do. The plate member 111 on the back surface may be provided with a groove-shaped space (hereinafter referred to as “accommodating groove 112”) in which the two shaft members 121 can be accommodated. By housing the two shaft members 121 in the housing groove 112, the volume of the shaft member 121 does not expand even if the two plate members 111 are bonded together, and the appearance is not impaired. Of course, instead of (or in addition to) the plate member 111 on the back surface, the receiving groove 112 may be provided in the plate member 111 on the front surface.

  With the back plate member 111 arranged at a predetermined position, the front plate member 111 is also arranged at a predetermined position, that is, bonded (joined) with the structural reinforcement 120 sandwiched therebetween, and the two plate members 111 are bonded together. Then, the wall member 110 is formed (Step 30: FIG. 2). When the wall body consisting of the wall member 110 and the structural reinforcement 120 can be installed, the gap 140 provided between the upper beam BU and the lower beam BL is filled with a filler 140 such as concrete or mortar (Step 60: FIG. 2). All steps are completed.

(Second example)
The second example is a method of constructing the non-structural wall 100 of the present invention between a concrete upper beam BU and a concrete lower beam BL, and carries “semi-finished product” after that. This is a method of installing the remaining loaded plate member 111. Here, the semi-finished product is obtained by integrating one plate member 111 of the two plate members 111 constituting the wall member 110 and the two shaft members 121 combined in an X shape.

  FIG. 7 is an explanatory view showing a procedure for constructing the wall member 110 by installing the remaining plate member 111 after installing the semi-finished product. FIG. 7A shows the fixing tool 130 and the tip muscle 121A with the upper beam BU. (B) shows a state where the semi-finished product is arranged at a predetermined position, (c) shows a state where the remaining plate member 111 is arranged, and (d) shows a clogging. A state in which the material 140 is filled is shown. As shown in this figure, as in the first example, the fixing device 130 is first installed (Step 10: FIG. 2). In this case, as shown in FIG. 5, it is preferable to adopt a method in which the tip muscle 121 </ b> A is fixed to the fixing tool 130 in advance.

  While the fixing tool 130 is installed, a semi-finished product is manufactured at a yard near the factory or the site. In the semi-finished product, as shown in FIG. 7B, the tips of the two shaft members 121 protrude from the plate member 111. Further, a connecting tool 122 is attached to the protruding portion. And the shaft member 121 and the tip muscle 121A are connected using this connecting tool 122. The plate member 111 constituting the semi-finished product may be provided with an accommodation groove 112 that can accommodate the shaft member 121 and the connector 122.

  When the semi-finished product can be installed, the remaining plate members 111 are arranged at predetermined positions as in the first example, that is, bonded (joined) with the structural reinforcement 120 sandwiched therebetween, and the two plate members 111 are bonded together. Then, the wall member 110 is formed (Step 30: FIG. 2). When the wall body consisting of the wall member 110 and the structural reinforcement 120 can be installed, the gap 140 provided between the upper beam BU and the lower beam BL is filled with a filler 140 such as concrete or mortar (Step 60: FIG. 2). All steps are completed.

(Third example)
A third example is a method for constructing the non-structural wall 100 of the present invention between a concrete upper beam BU and a concrete lower beam BL, in which the wall member 110 and the structural bar 120 are integrated. This is a method of carrying in a ready-made “off-the-shelf wall” and installing it as it is.

  As in the first example, the fixing tool 130 is first installed (Step 10: FIG. 2). In this case as well, as in the second example, the method shown in FIG. While the fixing device 130 is installed, a wall body is manufactured in a yard near the factory or the site (Step 40: FIG. 2). In this ready-made wall body, the tips of the two shaft members 121 protrude from the plate member 111 as in the semi-finished product of the second example, and a connecting tool 122 is attached to the protruding portion. Then, using this connector 122, the shaft member 121 and the tip muscle 121A are connected to each other, and an existing wall body is installed (Step 50: FIG. 2). One (or both) plate members 111 constituting the wall member 110 may be provided with an accommodation groove 112 that can accommodate the shaft member 121 and the connector 122.

  When the ready-made wall can be installed, as in the first example, the gap provided between the upper beam BU and the lower beam BL is filled with a filler 140 such as concrete or mortar (Step 60: FIG. 2). All steps are completed.

(Fourth example)
A fourth example is a method of constructing the non-structural wall 100 of the present invention between a steel-structured upper beam BU and a steel-structured lower beam BL, and a fixing tool 130 different from the above examples. Is characterized by its use. FIG. 8 is an explanatory view showing a fixing tool 130 used for a steel beam. FIG. 8A is a front view showing the fixing tool 130 attached to the upper beam BU and the lower beam BL, and FIG. It is a fragmentary sectional view which shows the fixing tool 130 attached to the beam BU.

  The upper beam BU and the lower beam BL shown in FIG. 8 use H-shaped steel, and a steel fixing tool 130 is welded and fixed to two locations of the upper beam BU and two locations of the lower beam BL. The fixing tool 130 is a so-called gusset plate, and is formed of a thin steel plate as can be seen from FIG.

  FIG. 9 is an explanatory view showing a procedure for constructing the non-structural wall 100 on a steel beam, wherein (a) shows a state in which the shaft member 121 is installed on the steel upper beam BU and the lower beam BL, (B) shows the state which arrange | positions the back plate member 111, (c) shows the state which arrange | positions the front plate member 111, (d) shows the state which filled the padding material 140. FIG. As shown in this figure, first, the fixing tool 130 (gusset plate) is welded and fixed to the upper beam BU and the lower beam BL (Step 10: FIG. 2).

  Next, the shaft member 121 made of flat steel is fixed to the fixing tool 130 (Step 20: FIG. 2). In this case, the attachment plate 123 and the fixing tool 130 which are bolted to the tip of the shaft member 121 are bolted. The attachment plates 123 are attached as a set of two sheets at one location, and the fixing tool 130 is sandwiched and fixed between the two attachment plates 123. Of the two plate members 111 constituting the wall member 110, the back plate member 111 is arranged at a predetermined position, and the front plate member 111 is also arranged at a predetermined position, that is, with the structural reinforcement 120 sandwiched therebetween. The wall member 110 is formed by bonding (bonding) and bonding the two plate members 111 together (Step 30: FIG. 2). When the wall body consisting of the wall member 110 and the structural reinforcement 120 can be installed, the gap 140 provided between the upper beam BU and the lower beam BL is filled with a filler 140 such as concrete or mortar (Step 60: FIG. 2). All steps are completed. One (or both) of the two plate members 111 may be provided with an accommodation groove 112 that can accommodate the two shaft members 121.

  Here, as a method of constructing the non-structural wall 100 on the steel beam, the case where the wall member 110 and the structural bar 120 are separate members (that is, the same case as in the first example) has been described. Similarly to the example, a construction method using a semi-finished product can be used, and similarly to the third example, a construction method using a ready-made wall can be used.

  The non-structural non-structural wall and the non-structural wall construction method of the present invention can be used in a variety of buildings such as a production facility such as a factory, a warehouse, and a gymnasium, in addition to a detached house and an apartment house.
