【Example】

Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings.

[0015] FIG. 1 is a diagram showing a wood screw according to an embodiment of the present invention.

[0016] This wood screw 20 is composed of a wood screw main body 22 and a C ring 24.

[0017] The wood screw body 22 includes a screw head 26, a threaded portion 28, a non-threaded portion 30, and a fitting groove. 32. The screw head 26 and the screw portion 28 are located at the ends of the wood screw body 22, respectively. It is formed in the part. The non-threaded portion 30 is formed between the screw head 26 and the threaded portion 28. It is supposed to be done. Moreover, this non-threaded portion 30 is at least made of wood to which it is attached. The length is longer than the thickness of the The fitting groove 32 is formed between the threaded part 28 and the non-threaded part 3. 0, and is formed in an annular shape around the outer periphery.

[0018] The C-ring 24 prevents the wood screw body 20 from falling off the wood on which it is attached. A fitting groove between the threaded portion 28 and the non-threaded portion 30 of the wood screw main body 20. 32 so that it can be fitted freely.

[0019] Next, we will show the case where this wood screw 20 is used in a ceiling suspension structure with a hollow. This will be explained with reference to FIGS. 2 to 4. Here, we will combine multiple panels and This example shows a case where a ceiling suspension structure is adopted for a house using the panel construction method that uses wood as a structural member. ing.

[0020] This ceiling suspension structure is located under a plurality of floor panels 34 that constitute the floor of the upper floor, for example, the second floor. Assemble the ceiling suspension beams 36, roof verandas 38, ceiling panels 40, etc. on the first floor to construct the ceiling of the first floor. has been completed.

[0021] The ceiling hanging beam 36 is located below the floor panel 34 and between the opposing wall panels. A plurality of them are provided in parallel at predetermined intervals so as to span over each other.

[0022] The field edge 38 is provided on the lower surface of each ceiling suspension beam 36 along the length direction of the ceiling suspension beam 36. It is now set up.

[0023] The field edge 38 also includes a plurality of wooden brackets that function as height-adjustable mounting members. It is designed to be attached to each ceiling suspension beam 36 using a cable 20, and this The field edge 38 and the ceiling suspension beam 36 are installed and integrated in advance at the factory. ing. In this case, as shown in FIG. Insert the wood screw body 22 into the hole 42, and insert the C ring 24 into the fitting groove 32 of the wood screw body 22. The threaded portion 28 is screwed into the ceiling hanging beam 36 in a state where it is fitted.

[0024] Further, the wood screws 20 are arranged at predetermined intervals, for example, at intervals of 455 to 910 mm. , and the distance l between the lower surface of the ceiling hanging beam 36 and the roof edge 38 can be adjusted by adjusting the wood screws 20. , can be adjusted. Here, at the time of shipment from the factory, the Increase the distance l between the ceiling hanging beam 36 and the field edge 38, and gradually The height is adjusted to make it smaller. In other words, in the center of the field edge 38, the weight of the ceiling It is set to be higher than both ends by an amount corresponding to the thickness and the amount of swelling.

[0025] The ceiling board 40 is designed to be attached directly to the lower surface of the roof edge 38, and By attaching the plate 40 to the lower surface of the field edge 38, the height of the lower surface of the field edge 38 can be increased. The difference automatically creates a bulge in which the center is slightly higher than the periphery. The sea urchin is turning.

[0026] Note that a heat insulating material 44 is disposed on the upper surface of the ceiling plate 40.

[0027] Next, the formation state of the ceiling will be explained.

[0028] First, the floor panel 34 that constitutes the floor of the upper floor of the house, for example, the second floor, is installed. In this case, a plurality of ceiling suspension beams 36 are arranged in parallel at predetermined intervals below the floor panel 34. Attach to.

[0029] In this case, the length of the ceiling suspension beam 36 is pre-installed on the bottom surface of the ceiling suspension beam 36 at the factory. A field edge 38 is integrated along the horizontal direction with wood screws 20, and this ceiling hanging beam 3 6, the field edge 38 will also be installed at the same time, and the field edge 38 will be installed at the same time. This will save you the trouble of attaching it.

[0030] Next, check the wood screws 20 at predetermined intervals that attach the field edge 38 to the ceiling hanging beam 36. Adjust the amount of protrusion of the field edge 38 from the lower surface of the ceiling hanging beam 36 to suit the construction site. Accordingly, adjust the height so that it is lower at both ends and slightly higher at the center.

[0031] In this case, when the screw body 22 is rotated, the non-threaded portion 30 is moved against the field edge 38. There is no change in the positional relationship between the screw body 22 and the edge 38 just by idling. , only the threaded portion 28 moves forward and backward relative to the ceiling hanging beam 36, allowing for easy and accurate height adjustment. It can be done. In addition, at the factory in advance, the central part of the field edge 38 is placed under the weight of the ceiling. The height is set higher than both ends by the amount of peeling and the amount of peeling. Adjustments can be made by making small adjustments to suit the conditions of the construction site, and the amount of peeling can be adjusted. can be easily done.

[0032] Then, ceiling panels 40 are sequentially laid on the lower surface of the roof edge 38 whose height has been adjusted as described above. If the height of the lower surface of the field edge 38 is different, the central part will automatically be different from the peripheral part. This results in the formation of a slightly high, curved ceiling.

[0033] Therefore, you can easily and reliably install the ceiling in a curved state without relying on experts. It becomes possible to form.

[0034] Also, the field edge 38 can be attached directly to the lower surface of the ceiling hanging beam 36 without using hanging trees. Therefore, the ceiling area can be made smaller by the amount of hanging trees, the ceiling can be made higher, and the interior space can be sufficiently increased. This makes it possible to secure it in minutes.

[0035] Note that the present invention is not limited to the above-mentioned embodiments, but can be applied to various modifications within the scope of the gist of the present invention. It is possible to provide

[0036] For example, in the embodiment described above, a plurality of panels are combined and each panel is formed into a structure. Although the panel construction method used as an example is shown, it is not limited to this panel construction method. It can also be adopted when building using construction methods or other various construction methods. Ru.

[0037] In addition, it is not always necessary to adjust the height of the field edge 38 at the time of shipment from the factory. Instead, the factory adjustment may be omitted, or the factory adjustment may be rough. It is also possible to stop it to the extent that it is properly adjusted.

[0038] In addition, in the above embodiment, the present invention was used for adjusting the bulge of the ceiling, but the present invention is The present invention is not limited to this, and can be used for various purposes as necessary.

[0039]
