Abstract

(57) [Summary] [Purpose] It is possible to reliably prevent the sill from floating (warping) or twisting even when a force due to drying or the like acts on the sill when the sill is attached to the concrete floor. [Structure] A plurality of wooden blocks are fixed to a concrete floor via hole-in anchors, and a sill is placed on these wooden blocks, and the recess formed on the back side is fitted with the upper end of the wooden block. And the both are bonded with the adhesive applied to the inner surface of the recess.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a sill mounting structure for a concrete floor.

[0002]

[Prior Art]

 FIG. 4 shows a conventional sill mounting structure for a concrete floor. As shown in the figure, conventionally, a plurality of wood pieces b, which are adjusted to a desired plate thickness so as to correct the unevenness and inclination of the concrete floor a, are attached to the concrete floor a with an adhesive c and are concrete. They were fixed with nails d, and a sill f was attached and fixed to the upper surface of these wood pieces b with an adhesive e.

However, in the above-mentioned conventional example, since the concrete floor a and the piece of wood b are adhered, the adhesive force at this portion is weak, and the fixing force by the concrete nail d is extremely small, so that the sill may be dried. Due to the action of force, the adhesive surface between the concrete floor a and the piece of wood b was easily peeled off, and the sill floated (warpage) or twisted, which required reworking in many cases.

[0004]

[Problems to be solved by the device]

 In view of the above conventional drawbacks, the present invention provides a robust sill mounting structure capable of reliably preventing the sill from floating (warping) or twisting even when a force due to drying or the like acts on the sill. .

[0005]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, in the present invention, a plurality of wooden blocks arranged at appropriate intervals on a concrete floor are fixed through hole-in anchors, and the wooden blocks are placed on the wooden block and on the back side. A sill formed with a recess corresponding to the block is laid with the recess fitted to the upper end of the wooden block, and the two are bonded together. The wooden block may be a block obtained by cutting a lumber or the like into a required size, or may be a block obtained by hardening wood chips with an adhesive.

[0006]

[Action]

 According to the above configuration, since the wooden block is fixed to the concrete floor via the hole-in anchor, the wooden block is reliably fixed to the concrete floor. In other words, if concrete and wood blocks are fixed together with an adhesive, different materials are bonded together, so the adhesive strength is rather weak, and the concrete floor must be thoroughly cleaned prior to bonding. Otherwise, poor cleaning will immediately cause poor adhesion, but when using a hole-in anchor, there is no such concern.

The wooden block and the sill are adhered with an adhesive, but since they are made of the same material, the bonding strength is high, and moreover, since the concave portion on the back surface of the sill is fitted to the upper end of the wooden block, There is no risk that the sill will be displaced in the horizontal direction with respect to the wooden block, and the bottom surface and side surfaces of the recess (the upper surface and the side surface of the wooden block) will become the adhesive surfaces, so that a large adhesive area can be secured. A large adhesive strength can be secured, and there is no risk that the sill will be displaced vertically with respect to the wooden block.

【Example】

 As shown in FIGS. 1 to 3, a plurality of wood blocks 2 are arranged on a concrete floor 1 at appropriate intervals (for example, 900 mm pitch) and fixed to hole-in anchors 3. The wood block 2 is formed by cutting square timber, and has dimensions of 50 mm in length and width and about 30 mm in height (the height is set according to the levelness of the concrete floor 1). . Reference numeral 3a is a cylindrical hole-in anchor main body, and 3B is a shaft body with a head of the hole-in anchor that is inserted into the main body 3a to be expanded and deformed.

On the other hand, on the back surface of the sill (which is made of wood) 4, a plurality of concave portions 5 ... Corresponding to the wooden blocks 2 are previously formed. Then, with the adhesive 6 applied to the bottom surface and the side surface of the concave portion 5 (or the upper surface and the side surface of the wooden block 2), the sill 4 is placed on the wooden block 2, and the concave portion 5 is the wooden block. It is laid in a state of being fitted to the upper ends of 2 ..., and the both 4, 2 ...

According to the above configuration, the wooden blocks 2 are fixed to the concrete floor 1 via the hole-in anchors 3, so that the wooden blocks 2 are reliably fixed to the concrete floor 1.

The wooden blocks 2 and the sill 4 are adhered to each other with an adhesive 6, but since they are made of the same material (made of wood), the adhesive strength is high, and the recesses 5 on the back surface of the sill 4 are made of a wooden block. Since the sill 4 is fitted to the upper ends of the wooden blocks 2, there is no risk of the sill 4 being displaced in the horizontal direction with respect to the wooden blocks 2, and the bottom and side surfaces of the concave portions 5 (the upper surface of the wooden blocks). Since the side surface) is the adhesive surface, the adhesive area is large and a large adhesive strength can be secured. Therefore, even if a force for deforming the sill 4 is applied due to drying of the sill 4, the sill 4 can be securely attached, and floating (warping) or twisting of the sill 4 can be prevented.

In the illustrated embodiment, the adhesive 7 is also used to fix the wooden block 2 and the concrete floor 1, but the adhesive 7 can be omitted. 8 in the figure indicates a tatami mat.

[0013]

[Effect of the device]

 As described above, according to the present invention, the sill can be securely attached, and even if a force due to drying or the like acts on the sill, the sill can be surely prevented from floating (warping) or twisting. .
