Description

[Technical Field]

[0001] The present invention relates to the technical field of a support structure for an upper frame that is provided on the upper end edge of a vertical support column to form a partition that divides an indoor space or a wall surface of a prefabricated building. [Background technology]

[0002] Generally, when erecting partitions to separate indoor spaces or structures such as prefabricated buildings, an upper frame is attached and supported between the upper edges of adjacent vertical posts on the left and right.In this case, the support structure for the upper frame is an attachment structure in which the upper frame is fitted externally to the upper edges of the vertical posts.One type of attachment structure is where the upper frame is arranged above the vertical posts, giving the upper frame a continuous appearance from left to right, and another type is where the upper frame is arranged on the left and right sides of the vertical posts, giving the upper frame an appearance divided into left and right parts by the vertical posts. When adopting the latter appearance, there are some that use a so-called "internal fascia" specification in which a groove is formed in the upper edge of the vertical support and the upper frame is fitted into the groove (see, for example, Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2002-138606 Summary of the Invention [Problem to be solved by the invention]

[0004] In order to assemble the upper frame according to the above-mentioned inner fascia specifications, it is necessary to form a groove in the upper edge of the vertical support to fit and support the upper frame. However, if the vertical support is hollow and tubular, forming the groove requires cutting the upper edge of the vertical support vertically to form a pair of groove side edges, and cutting horizontally to form the groove bottom. However, cutting the groove bottom cannot be done simply by cutting from the upper edge of the vertical support, as is the case with groove side edges, and requires special skilled work, which results in poor workability. When such cutting work is carried out at an actual construction site, one approach is to cut a pair of groove side edges, and then repeatedly bend the inner (tip) ends of the cut groove side edges to cause metal fatigue and then separate them, thereby easily forming a recessed groove. However, in this case, problems arise such as the cut edges becoming uneven due to metal fatigue, resulting in a poor appearance, and gaps forming between the inserted upper frame, and these are issues that the present invention aims to solve. [Means for solving the problem]

[0008] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. In the drawings, reference numeral 1 denotes a prefabricated building, which is configured with a wall portion 2 surrounding the building on all four sides and a roof portion 3 placed on the upper edge of the wall portion 2. The wall section 2 is composed of vertical posts (vertical frames) 4 erected on the floor surface F, wall panel bodies (which may have windows or may be door bodies) 5 interposed between adjacent vertical posts 4, and an upper frame 6 attached to and supported by the upper edge of the vertical posts 4 to form a four-sided frame on the ceiling side. On the other hand, the roof section 3 is composed of a ceiling rail 7 fastened to the upper surface of the upper frame 6, a rib material 7a arranged between the middle parts of the front and rear or left and right upper frames 6, and a roof panel body 8 fitted into a U-shaped fitting groove provided in the ceiling rail 7 and the rib material 7a. From here on, we will provide a detailed description of the configuration for assembling and supporting the upper frame 6 to the upper edge of the vertical support 4 in which the present invention is implemented.As all other configurations are conventional, detailed explanations will be omitted unless otherwise specified.

[0009] The vertical support 4 has a rectangular cylindrical shape and is configured with support surface portions 4a that form the surfaces of all four sides of the vertical support 4, and support corner portions 4c that are formed by extending in a "←" shape radially outward from each right-angle corner end portion 4b of the support surface portion 4a. The support corner portions 4c are formed to protrude from the support surface portion 4a, so that the support surface portions 4a are configured to be recessed (groove-shaped) into corner piece portions 4d that are bent at right angles at the tip ends of the support corner portions 4c, and the wall portion 2 is configured by fitting the wall panel body 5 between the recessed corner piece portions 4d of adjacent support corner portions 4c.

[0010] Reference numeral 9 denotes a cap material provided to attach and support the upper frame 6 to the upper edge of the vertical support 4, and is formed using a polymer resin material such as polystyrene, polypropylene, or polyvinyl chloride. The lower half 9a of the cap material 9 is rectangular cylindrical in shape and is configured to be inserted and removed freely from above into the upper edge of the support surface portion 4a. In contrast, the upper half 9b of the cap material 9 is formed in approximately the same shape as the outer shape of the vertical support 4 so that it can be engaged by being placed on the upper edge of the vertical support 4 from above, with the thickness of the lower half 9a added to the wall thickness (the inner cylindrical surfaces of the upper and lower halves 9a and 9b being flush), and is provided with cap surface portions 9c and 9d and a cap corner portion 9e. Incidentally, the upper half portion 9b of the cap material is engaged with the vertical support 4 in such a manner that the outer shapes of the cap surface portions 9c, 9d and cap corner portions 9e are substantially the same as the outer shape of the vertical support 4, allowing the entire circumference to rest on them. Specifically, the cap surface portions 9c, 9d are thicker in a stepped manner than the cap lower half portion 9a, and the cap corner portion 9e has a right-angled corner piece 9h formed thereon that is the same shape as the corner piece 4d formed by bending at a right angle on the support corner portion 4c, allowing the cap material to be placed on the support corner portion 4c in an engaged manner. However, the present invention is not limited to such an engaging type of mounting, but may be configured so that the mounting is on either the cap surface portion 9c, 9d, or the cap corner portion 9e, or even so that a locking protrusion or the like is provided on a portion of these portions to lock onto the upper edge of the vertical support 4.

[0011] The cap materials 9 are prepared as follows: a straight-line cap material 9S into which the upper frame 6 is inserted in a straight line, and a right-angle cap material 9R into which the upper frame 6 is inserted in a right-angle manner.These cap materials 9S and 9R basically have the same structure except for the location where the groove 9f described below is formed.Therefore, the structure of the straight-line cap material 9 (9S) will be described in detail below, and the structure of the right-angle cap material 9R will be described in detail by referring to the description of the straight-line cap material 9S, with the same reference symbols used unless otherwise required.

[0012] As described above, the straight-line cap material 9 (9S) has cap surface portions 9c, 9d and a cap corner portion 9e formed on the upper half portion 9b, and the pair of cap surface portions 9c that face each other in a straight line (left and right or front and back) so that the straight-line upper frame 6 can be fitted into has a notch on the upper half side, and a groove 9f is formed so that the upper frame 6 can be fitted into the inner capping specification described above, thereby forming a groove piece portion in which the groove 9f is formed. In contrast, the upper edge portions of the cap corner portions 9e on both sides sandwiching the cap surface portion 9d in the portion where the groove 9f is not formed, in other words, the portion where the upper frame 6 is not fitted, are connected via the connecting rod portion 9g, and the upper edge portion of the cap surface portion 9d in the portion where the upper frame 6 is not fitted is configured to reach the connecting rod portion 9g. By connecting the upper edge portions of the cap corner portions 9e together by the connecting rod portion 9g in this way, the cap material 9 is reinforced in the portion where the groove 9f is not formed by the cap corner portions 9e and the connecting rod portion 9g as a U-shaped aggregate structure.

[0013] On the other hand, the upper frame 6 is U-shaped (it goes without saying that it can be U-shaped or U-shaped, such as a U-shaped one with a lower surface, as long as it is a shape that can implement the present invention), and has an upper frame upper surface portion 6a and a pair of upper frame surface portions 6b hanging down from both end edges of the upper frame upper surface portion 6a.When the upper frame 6 is fitted into the groove 9f, the upper frame upper surface portion 6a is flush with the upper surface portion of the connecting rod portion 9g or protrudes slightly upward, so as to serve as a reference surface for assembling the ceiling rail 7 and rib material 7a that constitute the roof portion 3.

[0014] Furthermore, the cap surface portion 9d in the area where the recessed groove 9f is not formed extends to the connecting rod portion 9g as described above, and is configured to cover the area surrounded by the cap corner portion 9e and the connecting rod portion 9g without any gaps. The cap surface portion 9d abuts or closely faces the upper frame surface portion 6b of the upper frame 6 when it is fitted into the recessed groove 6f, and by fastening the upper frame surface portion 6b thereto via screws (bolts) 10 threaded into the cap surface portion 9d, the upper frame 6 is fastened integrally to the cap material 9, and the cap surface portion 9d thereby constitutes a fastening piece for fastening the upper frame surface portion 6b. Incidentally, in this embodiment, the cap material surface portion 9d, which serves as the fastening piece, is tall enough to reach the connecting rod portion 9g, but this is not necessary, and it is of course acceptable for there to be a gap (space) between it and the connecting rod portion 9g as long as it is capable of fastening the upper frame surface portion 6b. Furthermore, as described above, the cap material 9 and the upper frame 6 are integrated by fastening the cap surface portion 9d and the upper frame surface portion 6b together with screws 10, but as shown in Figure 4, it is also possible to fasten the lower half portion 9a of the cap material and the support surface portion 4a together with screws 10.In this case, although it does not result in an integrated structure including the upper frame 6 as described above, it is possible to integrate the cap material 9 and the vertical support 4, thereby increasing strength. In the above embodiment, the screws 10 are fastened only on one side (the front side) of the front and back sides, but it goes without saying that the screws 10 may be fastened from both the front and back sides.

[0015] Furthermore, in this embodiment, a batten 11 that can be detachably engaged with the edge of the post corner 4c is attached to the post surface 4a of the portion where the upper frame 6 of the vertical post 4 is not installed, and the post surface 4a of that portion is covered by the batten 11. For this reason, a locking piece 4e is provided at the tip edge of the corner piece 4d of the post corner 4c, for locking with a locking claw 11a provided on the batten 11. The batten 11 is arranged with a gap between it and the pillar surface plate 4a that it covers, but the batten 11 extends upward from the upper edge of the vertical pillar 4 and reaches the connecting rod portion 9g, and the locking protrusion 9i provided on the cap corner portion 9e is configured to engage with the locking claw 11a of the batten 11.As a result, the batten 11 covers the cap surface portion 9d, which is the fastening piece portion mentioned above, with a gap in the same state as the pillar surface portion 4a, so that the fastening screw 10 is not visible. In this embodiment, the cap material 9 is configured to be attached to the vertical support 4 by fitting the lower half 9a thereto, but it may also be configured to fasten the cap lower half 9a with a screw threaded into the support surface portion 4a, in which case the screw will be covered by the batten 11, just like the screw 10 threaded into the cap surface portion 9d.

[0016] The upper frame 6 can then be fitted into the groove 9f formed in the cap material 9 fitted into the upper edge of the vertical support 4, thereby enabling the installation of an inner fascia specification for the upper frame 6. As mentioned above, straight-line cap material 9S and right-angle cap material 9R are available as cap materials 9. The straight-line cap material 9S has a pair of linearly opposing cap surface portions 9c which serve as groove pieces, forming a groove 9f. By fitting the upper frame 6 into this groove 9f, the straight-line upper frame 6 is supported in a fitted state in the groove 9f arranged above the vertical support 4. In contrast, the right-angle cap material 9R has a groove 9f formed by the adjacent cap surface portions 9c, which become groove pieces via the cap corner portions 9e.The upper frame 6, which is bent at a right angle and arranged, is fitted into this groove 9f by, for example, butting together the tip edges cut at 45 degrees, so that the upper frame 6, bent at a right angle, is supported in a fitted and fitted state in the groove 9f arranged above the vertical support 4.

[0017] In this embodiment configured as described above, when the upper frame 6 is supported on the upper edge of the vertical support 4, which has a rectangular hollow cylindrical shape, in a state in which it forms an internal fascia, the cap material 9 is attached by fitting its lower half 9a into the upper edge of the vertical support 4. However, by fitting the upper frame 6 into the groove 9f formed in the upper half 9b of the cap material 9, the upper frame 6 can be fitted and supported by the vertical support 4 in an internal fascia manner. This eliminates the need for the conventional work of cutting out a groove on the upper edge of the vertical support 4, and also eliminates the need for work by an experienced worker. This allows the upper frame 6 to be assembled easily and reliably even on site, improving workability. Furthermore, in this case, the cap material 9 is attached to the vertical support by fitting the lower half 9a into the upper edge of the vertical support 4 so that it can be inserted and removed freely, and then engaging the lower edge of the upper half 9b with the upper edge of the vertical support 4, so that the cap material 9 can be easily attached to the vertical support 4, improving workability.

[0018] Furthermore, the upper half 9b of the cap material 9 is provided with a groove piece portion in which a groove 9f is formed for fitting and installing the upper frame 6, and a fastening piece portion for fastening the upper frame surface portion 6b of the upper frame 6 fitted into the groove 9f via a screw 10, as cap surface portions 9c and 9d.As a result, the upper frame 6 can be securely fitted and attached to the cap material 9, and the fitted upper frame and cap material 9 can be securely integrated, thereby increasing strength. Moreover, in this case, the vertical support 4 is composed of support corner portions 4c at the four corners and support surface portions 4a between adjacent support corner portions 4c, and the upper half portion 9b of the cap material 9 is composed of cap corner portions 9e that are placed in an engaging manner on the upper edge portion of the support corner portion 4c, and cap surface portions 9c, 9d between adjacent cap corner portions 9e, and of the cap surface portions 9c, 9d, the cap surface portion 9c at the portion where the groove 9f is formed and the upper frame 6 is incorporated serves as a groove piece portion, and the cap surface portion 9d at the portion where the upper frame is not incorporated serves as a fastening piece portion for fastening the upper frame surface portion 6b of the upper frame 6 that is fitted into the groove 9f via a screw 10, resulting in a simplified and consolidated structure of the cap material 9.

[0019] Furthermore, the upper edge portions of the cap corner portions 9e that sandwich the cap surface portion 9d that constitutes the fastening piece are connected via connecting rod portions 9g, so that these cap corner portions 9e and connecting rod portions 9g function as U-shaped aggregates, thereby reinforcing the cap material 9.Furthermore, the connecting rod portions 9g cover the cap surface portion 9d that constitutes the fastening piece from above, so that the cap surface portion 9d does not become flat and cannot be seen from above, thereby improving the appearance. Furthermore, the appearance of the vertical support 4 is improved by covering the support surface portion 4a of the vertical support 4 in the area where the upper frame 6 is not installed with a batten 11.The batten 11 has an upper edge portion extending above the support surface portion 4a and covering the cap surface portion 9d which constitutes the fastening piece portion, so that the fastening screws 10 are covered, thereby improving the appearance while fastening with the screws 10. Furthermore, although the batten 11 is provided with a gap between it and the support surface portion 4a and the cap surface portion 9d, the gap between the batten 11 and the cap surface portion 9d is covered from above by the connecting rod portion 9g and is not visible, thereby improving the appearance.

[0020] The cap material 9 configured in this manner includes a straight-line cap material 9S in which both linearly opposing cap surface portions 9c are configured as groove pieces and the upper frame is fitted in a straight line, and a right-angle cap material 9R in which a pair of cap surface portions 9c adjacent at right angles to each other through a cap corner portion 9e are configured as groove pieces and a pair of cap surface portions 9d arranged at right angles to each other through a cap corner portion 9e arranged diagonally from the cap corner portion 9e are configured as fastening pieces, and an upper frame 6 whose butting tip edges are cut at 45 degrees is fitted in at a right angle, thereby improving convenience.This can be used when assembling an upper frame 6 to something whose wall portion 2 is configured at a right angle, such as a prefabricated building 1. [Industrial Applicability]

[0021] The present invention can be used as a support structure for an upper frame that is attached to the upper edge of a vertical support column to form a partition that separates an indoor space or a wall surface of a prefabricated building. [Explanation of symbols]
