Column wooden wall structure

Abstract

To improve the workability of a concrete column to which a wooden wall is joined in consideration of the fact that, when a concrete column such as a reinforced concrete structure is cast-in-place, a complicated work such as temporary construction and removal of a form is generated and therefore the workability may be lowered.SOLUTION: A column wooden wall structure comprises a concrete column 10, a wall part 32, a column form part 34 filled with concrete 12 constituting the concrete column 10, and a wooden wall 30 joined to the concrete column 10. In the present column wooden wall structure, the wooden wall 30 is joined to the concrete column 10. The wooden wall 30 includes the wall part 32 and the column form part 34. The concrete column 10 is formed by filling the column form part 34 with the concrete 12 constituting the concrete column 10. Therefore, since the temporary installation and removal work of the form of the concrete column 10 is not required, the workability of the concrete column 10 is improved.SELECTED DRAWING: Figure 2

Description

[Technical field]

[0001] The present invention relates to a column-based wood wall structure. [Background technology]

[0002] Wooden walls joined to pillars are known (see, for example, Patent Documents 1 to 3). The wooden wall disclosed in Patent Document 1 is adhered to a pillar made of reinforced concrete. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2015-040402 A [Patent Document 2] JP 2019-065685 A [Patent Document 3] JP 2019-199759 A Summary of the Invention [Problem to be solved by the invention]

[0004] However, when concrete pillars of reinforced concrete construction or the like are cast in situ, complicated work such as the construction and removal of formwork is required, which may reduce workability.

[0005] In consideration of the above, the present invention aims to improve the workability of concrete pillars to which wooden walls are joined. [Means for solving the problem]

[0006] According to the first aspect The wooden-wall-column structure comprises a concrete column, a wall section, a column formwork section into which the concrete that constitutes the concrete column is filled, and a wooden wall joined to the concrete column.

[0007] First aspectAccording to the wood-wall-to-column structure, the wood wall is joined to a concrete column. The wood wall has a wall section and a column formwork section. The concrete column is formed by filling the column formwork section with concrete that constitutes the concrete column. This eliminates the need to temporarily install and remove the formwork for the concrete column, improving the workability of the concrete column.

[0008] According to the second aspect The pillar and wooden wall structure is According to the first aspect In a wooden-wall-column structure, the surface of the wall portion and the surface of the column formwork portion are flush with each other.

[0009] Second aspect According to the wooden-wall-to-column structure, the surface of the wall portion and the surface of the formwork portion for the column are flush with each other. Therefore, the present invention improves the design of the wooden wall compared to a case where there is a step between the surface of the wall portion and the surface of the formwork portion for the column.

[0010] In addition, by making the surface of the wall part and the surface of the column form part flush with each other, the shape of the concrete column is not visible in the wooden wall 30. Therefore, it is possible to present an appearance in which the concrete column does not exist.

[0011] According to the third aspect The pillar and wooden wall structure is First aspect or According to the second aspect In the wooden-wall-column structure, a recess into which the concrete is filled is formed on the inner peripheral surface of the column formwork portion.

[0012] Third aspect According to the above-mentioned wooden-wall-to-column structure, a recess is formed on the inner peripheral surface of the column formwork. The recess is filled with concrete that constitutes the concrete column. This allows shear force to be transmitted between the concrete column and the wooden wall through the concrete filled in the recess. In other words, the recess functions as a cotter.

[0013] In this way, in the present invention, by forming a recess on the inner surface of the column formwork section, the efficiency of shear force transmission between the concrete column and the wooden wall can be increased. Effect of the Invention

[0014] As described above, the wooden-wall-column structure of the present invention can improve the workability of the concrete pillar to which the wooden wall is joined. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0016] Hereinafter, a wooden-wall column structure according to one embodiment will be described with reference to the drawings.

[0017] (Column wood wall structure) 1 shows a plurality of concrete pillars 10 to which the wooden-wall-column structure according to this embodiment is applied, and a plurality of wooden walls 30. Note that the arrow X shown in each figure indicates the width direction of the wooden walls 30, and the arrow Y indicates the wall thickness direction (out-of-plane direction) of the wooden walls 30.

[0018] The multiple concrete pillars 10 are arranged at predetermined intervals in the width direction of the wooden wall 30. The multiple wooden walls 30 are stacked in a staggered pattern (checkerboard pattern) along the concrete pillars 10 to form a wall (exterior wall) of a structure (building). In addition, an opening 28 is formed between adjacent wooden walls 30 in the width direction.

[0019] (Concrete pillar) As shown in Fig. 2, the concrete pillar 10 is made of steel-reinforced concrete. The cross-sectional shape of the concrete pillar 10 is rectangular. The concrete pillar 10 has concrete 12 and an internal steel frame 14.

[0020] The concrete 12 is filled into a column form portion 34 of a wooden wall 30, which will be described later. An inner steel frame 14 and reinforcing bars (not shown) are embedded in the concrete 12. The inner steel frame 14 is formed, for example, from an H-shaped steel. Note that the inner steel frame 14 is not limited to an H-shaped steel, and may be formed from a C-shaped steel or a steel pipe, etc.

[0021] The inner steel frame 14 is provided with studs 16 for improving adhesion to the concrete 12. The studs 16 are embedded in the concrete 12. The studs 16 can be omitted.

[0022] A steel beam 20 is joined to the internal steel frame 14 via a gusset plate 22. The steel beam 20 is formed, for example, from an H-shaped steel, and is arranged along the wall thickness direction of the wooden wall 30 (the direction of the arrow Y).

[0023] (wooden wall) The wooden wall 30 is formed of, for example, CLT (Cross Laminated Timber), LVL (Laminated Veneer Lumber), laminated lumber, plywood, solid wood, etc. The wooden wall 30 has a wall section 32 and a pair of column formwork sections 34.

[0024] The wall portion 32 is formed in a rectangular wall shape and is disposed between adjacent concrete columns 10. A pair of column formwork portions 34 are provided at both ends in the width direction of the wall portion 32. The pair of column formwork portions 34 are provided along the ends in the width direction of the wall portion 32. Each column formwork portion 34 is formed in a tubular shape with a rectangular cross section that surrounds the concrete column 10.

[0025] The column formwork portion 34 has a through hole 36 extending in the vertical direction. The through hole 36 is formed in a rectangular shape. The internal steel frame 14 of the concrete column 10 is inserted into the through hole 36, and the concrete 12 is filled in the through hole 36.

[0026] Both side surfaces (wall surfaces) 32A, 32B of the wall section 32 and both side surfaces 34A, 34B of the column form section 34 are flush with each other. In other words, there is no step between both side surfaces 32A, 32B of the wall section 32 and both side surfaces 34A, 34B of the column form section 34. This prevents the column shape of the concrete column 10 from appearing in the wooden wall 30.

[0027] A slit 38 extending in the vertical direction is formed in the surface 32B on one side of the column form part 34. The slit 38 is formed over the entire axial length of the column form part 34. A gusset plate 22 for the steel beam 20 is inserted into this slit 38. As will be described later, after the gusset plate 22 is inserted, the slit 38 is filled with, for example, a sealing material (not shown) or the like.

[0028] As shown in Fig. 3, a plurality of recesses 40 are formed on the inner peripheral surface 34S of the column formwork portion 34 on the wall portion 32 side. The recesses 40 are formed at intervals in the vertical direction. By filling these recesses 40 with the concrete 12 of the concrete column 10, the efficiency of transmission of shear force between the concrete column 10 and the wooden wall 30 is improved.

[0029] The size, number and arrangement of the recesses 40 may be changed as appropriate. Also, the recesses 40 may be omitted.

[0030] (Construction method for wooden pillar wall structure) Next, an example of a construction method for the wooden-wall-pillar structure according to this embodiment will be described.

[0031] First, as shown in Figures 4 and 5, the inner steel frames 14 of the multiple concrete columns 10 are erected. At this time, the inner steel frames 14 are arranged in two horizontal directions (arrow X direction and arrow Y direction) that intersect (orthogonal to) each other.

[0032] 5, a steel beam 20 is erected on the inner steel frame 14 arranged in the direction of the arrow Y. More specifically, the end of the steel beam 20 is joined to the inner steel frame 14 via a gusset plate 22.

[0033] Next, as shown in Fig. 4, multiple wooden walls 30 are stacked in a staggered pattern so as not to reach the steel beams 20. At this time, the internal steel frame 14 is inserted into the column formwork portion 34 of each wooden wall 30, and the gusset plate 22 (see Fig. 5) is inserted into the slit 38 (see Fig. 2) formed in the column formwork portion 34. After that, the slit 38 is sealed with a sealing material (not shown) or the like.

[0034] 6, a slab 50 is constructed on the steel beams 20. Next, concrete 12 is filled (poured) into the column formwork 34 of each wooden wall 30 from above the slab 50 using a hose 52 or the like, and allowed to harden. As a result, the concrete columns 10 are formed, and the wooden walls 30 are joined to the concrete columns 10.

[0035] By repeating the above steps, a plurality of wooden walls 30 are stacked in a staggered pattern as shown in FIG.

[0036] The construction method for the concrete pillar 10 and the wooden wall 30 is not limited to the above-mentioned method, and steps may be interchanged or other steps may be added depending on the situation.

[0037] (effect) Next, the effects of this embodiment will be described.

[0038] As shown in Fig. 2, according to this embodiment, the wooden wall 30 has a wall section 32 and a pair of column formwork sections 34. The pair of column formwork sections 34 are filled with concrete 12 that constitutes the concrete column 10. In this way, the concrete column 10 is formed.

[0039] Therefore, in this embodiment, the need for temporary construction and removal of formwork for the concrete pillar 10 is eliminated, improving the workability of the concrete pillar 10.

[0040] In addition, the surfaces 32A, 32B on both sides of the wall section 32 and the surfaces 34A, 34B of the column form section 34 are flush with each other. Therefore, in this embodiment, the design of the wooden wall 30 is improved compared to a case where there is a step between the surfaces 32A, 32B of the wall section 32 and the surfaces 34A, 34B of the column form section 34.

[0041] In addition, by making the surfaces 32A, 32B of the wall portion 32 flush with the surfaces 32A, 32B of the column form portion 34, the column shape of the concrete column 10 does not appear in the wooden wall 30. Therefore, it is possible to present an appearance in which the concrete column 10 does not exist.

[0042] 3, a plurality of recesses 40 are formed on the inner peripheral surface of the column formwork portion 34. These recesses 40 are filled with the concrete 12 that constitutes the concrete column 10. As a result, shear force is transmitted between the concrete column 10 and the wooden wall 30 via the concrete 12 filled in the recesses 40. In other words, the plurality of recesses 40 function as cotters.

[0043] In this manner, in this embodiment, by forming a plurality of recesses 40 on the inner peripheral surface of the column formwork portion 34, the efficiency of transmission of shear force between the concrete column 10 and the wooden wall 30 can be increased.

[0044] (Modification) Next, a modification of the above embodiment will be described.

[0045] In the above embodiment, two concrete pillars 10 are joined to the wooden wall 30. However, for example, as in a modified example shown in Fig. 7, three concrete pillars 10 may be joined to the central wooden wall 30. In this case, the number of column formwork sections 34 (see Fig. 2) may be three depending on the number of concrete pillars 10, or two internal steel frames 14 may be inserted into one column formwork section 34 (see Fig. 2) with a wider width.

[0046] In the above embodiment, the column form portion 34 is provided at the end portion in the width direction of the wall portion 32. However, the column form portion may be provided in the middle portion of the wall portion 32 in the width direction.

[0047] Furthermore, the upper and lower ends of the wooden wall 30 may or may not coincide with the floor level of each floor.

[0048] In the above embodiment, the concrete column 10 is made of steel-reinforced concrete. However, for example, as in the modified example shown in Fig. 8, the concrete column 60 may be made of reinforced concrete. The concrete column 60 has concrete 12 and a plurality of column main bars 62 and shear reinforcement bars 64 embedded in the concrete 12.

[0049] As shown in a modified example in FIG. 9, the wooden wall 70 may be curved in plan view.

[0050] In the above embodiment, the surfaces 32A, 32B on both sides of the wall 32 and the surfaces 34A, 34B on both sides of the column form section 34 are flush with each other. However, for example, the surface 32A on one side of the wall 32 and the surface 34A on one side of the column form section 34 may be flush with each other, and a step (column-shaped) may be formed between the surface 32B on the other side of the wall 32 and the surface 34B on the other side of the column form section 34. It is also possible to form a step (column-shaped) between the surfaces 32A, 32B on both sides of the wall 32 and the surfaces 34A, 34B on both sides of the column form section 34.

[0051] In the above embodiment, the wooden walls 30 are stacked in a staggered pattern. However, the wooden walls are not limited to a staggered pattern, and may be stacked in a continuous manner in the vertical direction. The wooden walls may be installed individually without being stacked.

[0052] Although one embodiment of the present invention has been described above, the present invention is not limited to such an embodiment, and one embodiment and various modified examples may be used in appropriate combination, and it is of course possible to implement the present invention in various forms without departing from the gist of the present invention.
