Abstract

PROBLEM TO BE SOLVED: To provide a CLT (Cross Laminated Timber) material for enabling remarkable reduction in a labor cost and shortening of a construction period by making substrates for an upper floor and lower floor be finished simultaneously at the time of assembling a CLT which is a construction structure skeleton material, at a construction site without constructing an underfloor substrate of the upper floor and a ceiling substrate of the lower floor.SOLUTION: A CLT material 1 is used for a construction structure skeleton floor and has five layers or more and five plies or more. On the CLT material are provided through members 3 of timber etc. processed to polygons, with regular or irregular pitches.SELECTED DRAWING: Figure 3

Description

  The present invention relates to a CLT manufacturing method in which a building base material used in a wooden construction is provided with a floor base and a ceiling base and is already installed at the time of construction site delivery.

The present invention relates to a CLT building material in which a floor base and a ceiling base are applied to a building structural frame material used in a wooden building and are already provided and installed at the time of construction site delivery.

TECHNICAL FIELD The present invention relates to a construction method in which a floor structure and a ceiling floor are applied to a building structural frame material used in a wooden building and have already been installed at the time of construction site delivery.

  CLT is an abbreviation for Cross Laminated Timber, which is a thick panel in which plate-like wood layers are laminated and bonded so as to be orthogonal to each other. In conventional construction methods and framework construction methods for wooden buildings, roof materials are fired after assembling the building structural frame, and then the floor foundation, ceiling foundation, exterior and interior foundation foundations are constructed. Excessive labor was applied in the order of flooring construction, ceiling material construction, exterior material painting and interior finishing material construction. Moreover, in RC construction, after placing the frame (floor / ceiling), the ceiling of the lower floor and the floor of the upper floor are separately constructed, and then a method of constructing the floor foundation or ceiling foundation is used.

JP 2008-231702 A

  In a wooden construction site, the floor construction of the lower floor ceiling and the floor of the upper floor are performed separately in order to construct the floor foundation and ceiling foundation after the assembly of the building structural frame has been completed. ing. Similarly, the same construction is performed in the CLT structure. There was a problem that it required a labor cost and a construction period to install the foundation work. Therefore, the present inventors have developed a CLT in which the underfloor assembly and the ceiling foundation are already constructed at the time of carrying in the construction site without performing the construction for providing the floor foundation and the ceiling foundation at the construction site.

  The present invention is manufactured from wood, steel, plastic or the like processed into a square, a circle, or a polygon in dimensions of 20 mm to 180 mm in width, 20 mm to 500 mm in thickness, and 180 mm to 3 m in length. The first characteristic is that the penetrating member has been subjected to. Further, the second feature is that the CLT is processed by opening a square, round, or polygonal hole in the range of 10% to 100% of the thickness of the CLT.

  What can be used as the material of the penetrating member according to the present invention is not particularly limited, such as hardwood, conifer, laminated wood, bamboo, steel, PP, etc. Cedar or cedar laminated timber is suitable.

  The width and thickness of the penetrating member that can be used in the present invention are determined in the range of 20 mm to 180 mm in width and 20 mm to 500 mm in thickness depending on the type of floor finish material, the thickness of the interior heat insulating material, and the shape of the drain pipe and water supply pipe. The length is determined in the range of 180 mm to 3 m in the thickness of the CLT which is the casing and the ceiling height of the lower floor.

  In CLT hole spans, holes may be drilled regularly and irregularly in the CLT in 2, 3, 4, 5, 6 spans of dimensions adopted in the modular design of the structure.

  In addition, because the impact sound of the floor reverberates due to the penetrating member, a cushioning material is provided at the lower part of the penetrating member, and depending on the type of interior finish member of the ceiling, It has a built-in receptacle so that all screw bolts can be inserted.

The present invention has the following excellent effects.
(1) At the time of assembling the CLT, which is a building structural frame material at the construction site, the foundation is provided without the construction of the floor foundation and the ceiling foundation, which greatly reduces labor costs and the construction period. Shortening is possible.
(2) It is possible to reduce labor costs and facilitate construction by finishing interior materials without measuring the level at the construction site.
(3) Machining by the pre-cutting or laminating process stage, and since the substrate can be processed with high accuracy, the finish is beautiful.

BEST MODE FOR CARRYING OUT THE INVENTION

  First, as shown in FIG. 1, a 7-layer 7-ply cedar CLT material having a width W of 1000 mm and a length L of 3000 mm, a width w1: 100 mm, a length L1: 1000 mm, and L2 shown in FIGS. : 400 mm thickness w2: 40 mm cedar laminated wood penetrating members at a pitch of w1, w2, and w3 in the horizontal direction and at a pitch of L1, L2, L3, L4, L5, L6, L7, L8, and L9 in the vertical direction In addition, the CLT material previously opened to the dimension of w2 is penetrated.

  At the time of penetration as described above, the floor base and ceiling base are finished, and it is selected whether to construct the timber as shown in 6 of FIG. 3 or paste the plywood directly according to the finishing material. It is possible to select whether to construct the wood to be fielded as shown in 7 or to directly paste the board.

    Further, as shown in 8 of FIG. 4, a penetrating member 8 having a receiver 11 is used so that all screw bolts 9 corresponding to the light roof can be inserted, and a light sky clip 10 of FIG. 4 is attached and used.

  Next, as shown in FIG. 5, a cedar CLT material having a width W of 1000 mm and a length L of 3000 mm and 7 layers and 7 plies of length L1, L2, L3, L4, L5, L6, L7, L8, and L9, A CLT material is formed in advance in which holes are formed in squares, circles, and polygons at equal intervals at a pitch of horizontal w1, w2, and w3.

  The present invention is not limited to the above-described embodiment, and various applications are possible without departing from the spirit of the present invention. For example, the width of w1 and w2 in FIG. 4 is increased, and plywood can be pasted without installing wood as in 6 in FIG. 4, and steel and PP materials are attached with bolts and screws, etc. regardless of cedar. Members can be used and applied.
