Description

  The present invention relates to a reinforcing member that reinforces a framework of a simple greenhouse in which a large number of arched frames are erected in parallel.

As a simple greenhouse for agriculture, there is one in which a pillar is formed by inserting the pillars of an arch-shaped pipe frame in parallel to the ground at a predetermined pitch, and the outside of the framework is covered with a vinyl sheet. Such a simple greenhouse is lightweight and easy to install, dismantle, and remove, but sometimes it collapses when exposed to strong winds. In particular, the frame is weak against strong winds from the front of the skeleton (the direction passing through the arch), and when the end frame falls down, the adjacent frames may fall one after another. As a reinforcement measure, it has been proposed to connect adjacent frames using joint fittings having clamps attached to both ends, or to connect two frames by installing frames in the vertical direction inside and outside. It is also effective to attach braces like other buildings. Bracing can be exemplified by attaching clamps that grip the frame to both ends of the housing following the joint fitting (see Patent Documents 1 to 7).
Japanese Utility Model Publication No. 51-108410 Japanese Utility Model Publication No. 53-149404 Japanese Utility Model Publication No. 62-73105 Japanese Utility Model Publication No. 54-39333 Japanese Utility Model Publication No. 56-150354 Japanese Utility Model Publication No. 50-138805 Japanese Utility Model Publication No. 60-185453

  However, many arch-shaped frames are usually arranged at a pitch of about 500 mm, and in order to connect all the frames with joint brackets and braces, a large number of joint brackets and braces are required, and the mounting effort is enormous. It becomes. Of course, if a long bracing that spans multiple frames is used, the number of attachments can be reduced. However, since the conventional bracing is to attach a clamp on the extension of the axis of the frame and attach it between adjacent frames, it is not possible to install it by interfering with the straddled frame simply by increasing the length of the frame. . If you try to attach it too strongly, you must bend the housing, and the installation work is not easy.

  In view of the background art described above, an object of the present invention is to provide a simple greenhouse reinforcing member that can be easily attached.

  That is, the reinforcing member and the simple greenhouse of the present invention have the configurations described in [1] to [6] below.

A reinforcing member which is attached.

  [2] The two housings are engaged with each other in an intersecting state, and the grip centers of the two clamps on one end side of the two housings are located on the same axis, and the two clamp portions on the other end side are gripped. The reinforcing member according to claim 1, wherein an offset amount of a clamp portion in each housing is set so that the center is located on the same axis.

  [3] The reinforcement according to claim 1 or 2, wherein the clamp part is attached such that an attachment position in a length direction of the housing can be adjusted and an angle can be adjusted with respect to an axis of the housing. Element.

  [4] The reinforcing member according to any one of claims 1 to 3, wherein an offset amount of the clamp part is set by attaching the clamp part to a housing via a spacer.

  [5] The reinforcing member according to any one of claims 1 to 4, wherein an offset amount of the clamp portion is set by bending the casing.

  [6] A structure in which a large number of arch-shaped frames are erected in parallel, and a frame in which the columns of the erected frames form a side surface, and is attached to the side surface of the frame. A simple greenhouse comprising the reinforcing member described above.

  The reinforcing member according to the invention of [1] can be easily attached to the framework without interfering with the support straddled by the frame. In addition, since the casing has a length straddling at least one strut, the number of reinforcing members attached to the framework can be reduced.

  The reinforcing member according to the invention of [2] can give particularly high strength to the framework. Moreover, since the two housings do not interfere with each other, the mounting operation is simple.

  Since the reinforcing member according to the invention [3] can substantially adjust the length of the housing by adjusting the mounting position of the clamp portion, it is possible to cancel the error in the installation pitch of the columns.

  According to the reinforcing member concerning each invention of [4] [5], the offset amount of a clamp part can be set up appropriately.

  In the simple greenhouse according to the invention of [6], the side surface of the framework is reinforced by a reinforcing member.

  FIG. 1 shows an embodiment of a reinforcing member of the present invention, and FIG. 2 shows a framework of a simple greenhouse to which this reinforcing member is attached. Moreover, FIG. 3A and FIG. 3B are the principal part enlarged views which show the attachment state of a reinforcement member.

  The reinforcing member (1) shown in FIG. 1 is formed by attaching clamp portions (15a) (15b) (25a) (25b) to both ends of two skeletons (10) and (20) which are bracing and intersecting each other. is there.

  The casings (10) and (20) are each made of a metal pipe, and are engaged with each other by fastening bolts (30) and butternuts (31) at the center in the length direction. When the butternut (31) is loosened, the crossing angle (θ1) of the housings (10) and (20) can be freely adjusted, and when tightened, the angle (θ1) is fixed. Bracket portions (11a) (11b) (21a) (21b) are formed by crushing both ends of each housing (10) (20) into a flat plate shape, and in the length direction of the housing (10) (20). Long holes (12) and (22) for attaching the clamp portions (15a), (15b), (25a), and (25b) are drilled along. Further, one housing (10) is bent toward the other housing (20) in the vicinity of both bracket portions (11a) (11b), and the bracket portions (11a) (11b) are bent to the other housing ( 20) are present in the same plane as the bracket portions (21a) and (21b). The code | symbol (13) has shown the bending part of the housing (10).

  The clamp portions (15a), (15b), (25a), and (25b) each have a sandwiching portion (33) bent in a dogleg shape on the distal end side, and two sandwiching plates (35a) and (35b) arranged to face each other And bolts (36) and wing nuts (37) that are inserted into fastening holes (not shown) on the proximal end side of the clamping plates (35a) (35b) and fastened. An annular spacer (38) is welded to the base end side of one clamping plate (35b) at a position concentric with the mounting hole. Then, the spacer (38) is arranged on the side of the housing (10) (20), and the bolt (36) is clamped (15a) (15b) (25a) (25b). 35b) and the bracket portions (11a), (11b), (21a), and (21b) are sequentially inserted into the long holes (12) and (22), and the wing nut (37) is fastened. Thus, the clamp portions (15a) (15b) (25a) (25b) are attached at positions where the gripping centers of the sandwiching portions (33) (33) are offset with respect to the axis of the housing (10) (20). ing. In addition, since the two bracket portions (11a) and (21a) on one end side of the two housings (10) and (20) exist in the same plane, the two clamp portions (15a) and (25a) on one end side The gripping center exists on the same axis. Similarly, the grip centers of the two clamp portions (15b) and (25b) on the other end side are also coaxial.

  Further, when the clamp portions (15a) (15b) (25a) (25b) are attached to the housing (10) (20), the bolt (36) is slid in the long holes (12) (22). The mounting position in the length direction of the casings (10) and (20) can be adjusted by rotating the clamping plates (35a) and (35b) with respect to the bolt (36). 20), the mounting angle (θ2) with respect to the axis can be freely adjusted.

  The reinforcing member of the present invention may be composed of a single casing. The reinforcing member (2) shown in FIG. 2 includes a single casing (20) and clamp portions (25a) and (25b) attached to brackets at both ends thereof via spacers. In other words, it is composed of one casing (20) of the reinforcing member (1) and clamp portions (25a) and (25b) at both ends thereof. Since the shape of the clamp portions (25a) and (25b) and the method of attaching them to the flange (20) body are the same as those of the reinforcing member (1) described above, the description is omitted.

  As shown in FIG. 2, the framework of a simple greenhouse is an arcuate frame (40) formed by bending a metal pipe having a circular cross section, and a column (41) of the frame (40) is parallel to the ground at a predetermined pitch. Inserted, and a cross (42) is attached to the upper end of the support (41). A number of upright columns (41), (41),... Form the side surface of the framework.

  On the indoor side of each side part of the framework, first reinforcing members (1) having two housings at both ends are attached, and further, two second reinforcing members (2) having one housing between them. Is attached. Although all the frames (40) have the same shape, in the following, symbols (41a) and (41d) are attached to the struts gripped by the reinforcing members (1) and (2), and the reinforcing members (1) ( Description will be made with reference numerals (41b) and (41c) attached to the support straddled by 2).

  The casings (10) and (20) of the first reinforcing member (1) and the second reinforcing member (2) straddle two struts (41b) and (41c) in a state where they are diagonally installed as braces, The length is set such that the columns (41a) (41d) adjacent to the columns (41b) (41c) can be gripped.

  As shown in FIGS. 3A and 3B, the first reinforcing member (1) includes a clamp portion (15b) (25b) on one end side that holds the first support post (41a) and a clamp portion (15a on the other end side). ) (25a) adjusts the crossing angle (θ1) of the two housings (10) and (20) so that the fourth column (41d) is gripped. Then, the support columns (41a) and (41d) are sandwiched between the clamping portions (33) of the clamp portions (15b) (25b) and (15a) and (25a) so that the angle is 90 ° with respect to the support columns (41a) and (41d). The clamp nut (37) is tightened while adjusting the angle (θ2) of the clamp portions (15b), (25b), (15a), and (25a) to be fixed to the columns (41a) and (41c). At this time, the bolts (36) are appropriately slid in the long holes (12) (22) to adjust the positions of the clamp portions (15b) (25b) (15a) (25a). Further, if necessary, the crossing angle (θ1) of the two housings (10) and (20) may be readjusted. The length of the frame (10) (20) as the brace is the angle of intersection (θ1) of the two frames (10) (20) and the attachment of the clamps (15a) (25a) (15b) (25b) Since it can be adjusted depending on the position, the reinforcing member (1) can be attached to the frame without any trouble even if there is a slight error in the insertion pitch of the frame (40).

  The second reinforcing member (2) also straddles the two struts (41b) (41c) with the housing (20), and the first strut (41a) and the clamps (25b) (25a) at both ends. Grasp the fourth column (41d).

  The first reinforcing member (1) and the second reinforcing member (2) described above are attached to the indoor side of the side surface portion, and the clamp portions (15a) (25a) (15b) (25b) are framed by the spacer (38). (10) Since it is offset from the axis of (20), it can be easily mounted without interfering with the struts (41b) (41c) on which the housings (10) and (20) are straddled. Further, in the first reinforcing member (1), by bending one housing (10), two clamp portions (15a) (25a), (15b) (25b) on one end side and the other end side are coaxially arranged. Since the two housings (10) and (20) do not interfere with each other, the clamps (15b) of the two housings (10) and (20) can be attached to the one column (41a) and (41d) without interfering with each other. ) (25b), (15a) (25a) can be attached.

  In addition, since the individual reinforcing members (1) and (2) straddle the plurality of struts (41), the frame can be reinforced with a small number of reinforcing members, and the labor of the mounting work can be saved even when the number of reinforcing members is small. Can be planned.

  As described above, by attaching the reinforcing members (1) and (2) to the skeleton of the arched frame (40), the side surface becomes one large surface and the strength is improved. Further, the first reinforcing member (1) in which the two casings (10) and (20) intersect each other gives higher strength than the second reinforcing member (2) including the one casing (20). be able to. This reinforcement increases the strength especially against strong winds from the front (the direction of passing through the arch), and the frame (40) can be prevented from falling down like a shogi one after another.

  Further, in any of the reinforcing members (1) and (2), the clamp portions (33a) of the clamp portions (15a) (15b) (25a) (25b) are provided on the support columns (41a) (41d) outside the side surface portions. It exists only as if it is wound, and it can be said that there is almost no protrusion from the columns (41a) and (41d). For this reason, when the outside of the framework is covered with a vinyl sheet, a situation in which the reinforcing members (1) and (2) damage the vinyl sheet is avoided.

  The reinforcing member and the simple greenhouse of the present invention are not limited to the embodiment described above.

  The material of the casing is not limited to the pipe material, and may be a solid rod or a flat plate material. Moreover, it is not limited to a metal.

  The method of setting the offset amount of the clamp part is not limited to the spacer interposition or the bending of the casing in the above embodiment. As another setting method, a method of bending the proximal end side of the clamping plate of the clamp portion into an L shape can be exemplified. When a spacer is interposed, the sandwich plate and the spacer may be integrated by welding or the like as in the above embodiment, or may be used as a separate member without being joined. The merit of integrating the spacer is that the number of parts is reduced and the parts management and the taking operation are easy. On the other hand, if the spacer is a separate member, the offset amount can be changed by exchanging the spacer, so that the reinforcing member is highly versatile. In addition, when two chassis are crossed, in order to prevent both from interfering with each other and not to interfere with each other, different offset amounts will be set in each chassis. The same method may be used, or different methods may be combined. In the reinforcing member (1) of the illustrated example, one casing (10) sets an offset amount by bending the casing (10) and the spacer (38), and the other casing (20) is a spacer (38). Only set by.

  Moreover, it is preferable that a clamp part is attached so that position adjustment is possible in the length direction of a housing. When installing a framework of a simple greenhouse, an error in the insertion pitch of the frame (post) can usually occur, but if the length of the frame can be adjusted substantially depending on the mounting position of the clamp, Installation error can be canceled out. The means for adjusting the position of the clamp portion is not limited to that by sliding in the long holes (12) and (22) of the above embodiment. Further, the present invention does not exclude the case where the clamp portion is integrally attached to the housing. Moreover, the shape of the clamping part of a clamp part is not limited at all, and a semicircle can be illustrated as another shape. The pin-shaped clamping part of the example of illustration can respond | correspond to the support | pillar of a wide range of diameter rather than a semicircular thing, and its versatility is high. Of course, the clamp part is not limited to the one sandwiched between two sandwiching plates disposed opposite to each other, and may be based on another gripping method such as a tightening method.

  Moreover, in the simple greenhouse of the said embodiment, although the example which attached the cross type reinforcement member (1) or the one type reinforcement member (2) to all the support | pillars was shown, the number of attachments of a reinforcement member, a position, The combination is arbitrary. The case where the reinforcing member is attached to only a part of the side surface portion is also included in the simple greenhouse of the present invention. It goes without saying that higher strength can be imparted by using the cross-type reinforcing members (1) densely, but they may be appropriately combined depending on the required strength. Further, the shape of the frame is not limited as long as the columns are erected at a required pitch.

  Since the reinforcing member of the present invention can be attached without causing the long casing to interfere with the support, the number of reinforcing members is small, and the attaching operation is simple. Therefore, the framework of the simple greenhouse can be reinforced with a small amount of work.

It is a perspective view which shows one Embodiment of the reinforcement member of this invention. It is a perspective view which shows the state which attached the reinforcement member of this invention to the framework of the simple greenhouse. It is a principal part enlarged side view of FIG. It is a principal part expanded sectional view of FIG.
