Description

この発明は、鉛直方向の支柱と水平方向の梁とを連結する構造物用ブラケットに関する。   The present invention relates to a structural bracket for connecting a vertical column and a horizontal beam.

鉛直方向の支柱と水平方向の梁とを組んでガレージ、バルコニー、ベランダ、ステージ、作業台などの構造物を構築する場合、従来は、支柱にブラケットを溶接で固着し、そのブラケットと梁とをボルト、ナット等の連結具で連結する方法が広く採用されていた。   When constructing structures such as garages, balconies, verandas, stages, work benches, etc. by assembling vertical columns and horizontal beams, conventionally, brackets are fixed to the columns by welding, and the brackets and beams are connected to each other. A method of connecting with connecting tools such as bolts and nuts has been widely adopted.

また、土木の分野では、支保工や仮設足場等の仮設構造物を構築する場合に、予め所定の高さに受け金具が固着された支柱を用い、梁の端部に一体化された係止金具と前記受け金具とを係止させることにより、支柱と梁とを連結することが行われている(例えば特許文献1、2)。

In addition, a plurality of holding pieces (or fixed pieces) are arranged so as to surround the periphery of the support column, and the holding pieces are connected to each other by a connecting tool such as a bolt or a nut, and the holding pieces and the beam are connected by a connecting tool. By doing so, a technique for connecting the column and the beam is known (for example, Patent Documents 3 and 4).
Japanese Patent Laid-Open No. 2000-319987 JP 2003-311412 A

支柱にブラケットを溶接で固着する従来の方法は、現場での構築作業に先立つ溶接等の前工程が必要であるとともに、溶接による熱で支柱が劣化、変質する可能性があるという問題がある。また、特許文献1、2に記載の技術は、あくまでも仮設構造物用の技術であり、耐久性が求められる構造物には適せず、しかも支柱に対して梁を連結する高さが決まっているため、ガレージ、バルコニー等の場合には設置状況が異なる個々のケースに対応できないという問題がある。さらに、特許文献3、4に記載の技術は、支柱の周囲を囲むように配置した複数の挟持片(又は固定片)を適正位置に保ったまま互いに固着しなければならないという難しさと、支柱に固着された挟持片と梁とを該梁を適正高さに保ったまま連結具で連結しなければならないという難しさとがあるので、これらの作業を一人で行うのは非常に困難であり、作業効率が悪いという問題がある。   The conventional method of fixing the bracket to the support by welding requires a pre-process such as welding prior to the construction work on site, and there is a problem that the support may be deteriorated and deteriorated due to heat generated by welding. In addition, the techniques described in Patent Documents 1 and 2 are only for temporary structures, and are not suitable for structures that require durability, and the height at which the beam is connected to the column is determined. Therefore, in the case of garages, balconies, etc., there is a problem that it is not possible to deal with individual cases with different installation conditions. Furthermore, the techniques described in Patent Documents 3 and 4 have a difficulty in that a plurality of holding pieces (or fixed pieces) arranged so as to surround the support column must be fixed to each other while being held in an appropriate position. Since it is difficult to connect the fixed clamping piece and the beam with a connecting tool while maintaining the beam at an appropriate height, it is very difficult to perform these operations alone. There is a problem of inefficiency.

本発明は、上記従来技術の問題点を解決し、鉛直方向の支柱に対して水平方向の梁を任意の高さに容易に連結することのできる構造物用ブラケットを提供することを課題としている。   This invention solves the problem of the said prior art, and makes it a subject to provide the bracket for structures which can connect a horizontal beam to arbitrary height easily with respect to a vertical support | pillar. .

A lower bracket in which a connecting tool insertion hole for inserting a connecting tool for connecting the beam mounting portion and the lower parallel portion of the beam is formed in the part, and a support post insertion hole through which the support post is inserted, The column insertion hole is an incomplete hole partially communicating with the outside. An expansion / contraction tool insertion hole for inserting an expansion / contraction tool for expanding / contracting the post insertion hole by changing the interval between the both side portions is formed on the side portion, and an upper parallel portion of the beam is provided at a location different from the communication location. A beam mounting portion is provided, and a connecting tool insertion hole is formed in the beam mounting portion for inserting a connecting tool for connecting the beam mounting portion and the upper parallel portion of the beam. It is characterized by a pair with the bracket.

支柱挿通穴に支柱が挿通された下ブラケット及び上ブラケットを支柱に対して適正高さに位置させ、上下両ブラケットの拡縮具挿通穴に挿通した拡縮具により上下両ブラケットの支柱挿通穴の内径をそれぞれ調節して当該上下両ブラケットを支柱に固着する。そして、平行部分が上下に位置するように配置されたH鋼製の梁の下側平行部分を下ブラケットの梁載置部の上に載置し、該下ブラケットの連結具挿通穴に挿通した連結具により下ブラケットと梁の下側平行部分とを連結するとともに、前記梁の上側平行部分を上ブラケットの梁載置部の上に載置し、該上ブラケットの連結具挿通穴に挿通した連結具により上ブラケットと梁の上側平行部分とを連結する。   Position the lower bracket and upper bracket with the struts inserted into the strut insertion holes at appropriate heights with respect to the struts, and adjust the inner diameter of the strut insertion holes of the upper and lower brackets with the expansion / contraction tools inserted into the expansion / reduction tool insertion holes of the upper and lower brackets. Adjust the upper and lower brackets to the support. Then, the lower parallel part of the H steel beam arranged so that the parallel part is positioned up and down was placed on the beam placing part of the lower bracket, and inserted into the connector insertion hole of the lower bracket. The lower bracket and the lower parallel portion of the beam are connected by a connector, and the upper parallel portion of the beam is placed on the beam mounting portion of the upper bracket, and is inserted into the connector insertion hole of the upper bracket. The upper bracket and the upper parallel part of the beam are connected by a connector.

さらに、請求項3に記載の構造物用ブラケットは、請求項1又は2の内容に加えて、常態では支柱挿通穴の内径が支柱の外径よりも若干小さく、拡縮具挿通穴に挿通した拡縮具により支柱挿通穴を広げた状態で当該支柱挿通穴に支柱を挿通し、拡縮具を拡縮具挿通穴から抜いて支柱挿通穴を縮径させることにより、支柱挿通穴の内周面を支柱の外面に密着させて支柱に固着するようにした。   Furthermore, in addition to the contents of claim 1 or 2, the structural bracket according to claim 3 is an expansion / reduction that is normally inserted into the expansion / reduction tool insertion hole because the inner diameter of the column insertion hole is slightly smaller than the outer diameter of the column. Insert the strut into the strut insertion hole in a state where the strut insertion hole is widened by the tool, remove the expansion / contraction tool from the expansion / contraction tool insertion hole, and reduce the diameter of the strut insertion hole, so that the inner peripheral surface of the strut insertion hole is It was made to adhere to the outer surface and stick to the support.

請求項1乃至3に記載の発明による構造物用ブラケットは、支柱の任意の位置に固着させることが可能であるので、構造物の形態や設置状況に応じて梁の高さを任意に決めることができ、また、切り欠き部及び拡縮具で支柱挿通穴の内径を調節して当該ブラケットを支柱に固着するとともに、梁載置部の上に梁を載置した状態で当該ブラケットと梁とを連結する構成であるので、支柱と梁とを確実かつ容易に連結させることができ、さらに、溶接を行わないので、溶接による支柱や梁の劣化、変質を防ぐことができる。   Since the structural bracket according to the first to third aspects of the present invention can be fixed to an arbitrary position of the support column, the height of the beam is arbitrarily determined according to the form of the structure and the installation situation. The bracket is fixed to the column by adjusting the inner diameter of the column insertion hole with the notch and the expansion / contraction tool, and the bracket and the beam are mounted with the beam mounted on the beam mounting unit. Since it is the structure which connects, a support | pillar and a beam can be connected reliably and easily, and also, since welding is not performed, deterioration and quality change of a support | pillar and a beam by welding can be prevented.

特に、請求項2に記載の発明による構造物用ブラケットは、H鋼製の梁を支柱に連結するのに好適で、平行部分が上下に位置するように配置したH鋼製の梁の下側平行部分と下ブラケットと連結するとともに、該梁の上側平行部分と上ブラケットとを連結した構造は、堅牢かつ強固である。   In particular, the structural bracket according to the second aspect of the present invention is suitable for connecting an H-steel beam to a support column, and the lower side of the H-steel beam arranged so that parallel portions are positioned vertically. The structure in which the parallel portion and the lower bracket are connected and the upper parallel portion of the beam and the upper bracket are connected is robust and strong.

さらに、請求項3に記載の構成とすれば、予め拡縮具挿通穴に拡縮具を挿通して支柱挿通穴を広げた状態にしておくことにより、当該支柱挿通穴に支柱を挿通し、拡縮具を拡縮具挿通穴から抜くだけで、ブラケットを支柱に固着させることができるので、構造物の組立現場での作業が簡略化できるととともに、下ブラケット1及び上ブラケット11が常態で支柱41に固着しているので、その固着状態が安定するという効果を奏する。   Furthermore, if it is set as the structure of Claim 3, the expansion / contraction tool is inserted in the said column insertion hole by inserting the expansion / contraction tool in the expansion / contraction tool insertion hole beforehand, and making it the state which expanded the column insertion hole, Since the bracket can be fixed to the column by simply removing the expansion / contraction tool from the insertion hole, the work at the assembly site of the structure can be simplified, and the lower bracket 1 and the upper bracket 11 are fixed to the column 41 in a normal state. As a result, the fixed state is stabilized.

下ブラケットと上ブラケットとで一組とする。梁材として軽量H鋼等を使用する。下ブラケット及び上ブラケットを支柱の適正高さに固着し、平行部分が上下に位置するように配置した梁の下側平行部分を下ブラケットの梁載置部の上に載置して両者を連結するとともに、該梁の上側平行部分を上ブラケットの梁載置部の上に載置して両者を連結する。下ブラケットの梁載置部の下方に、該下ブラケットと一体に支柱の外面に当接する下支えプレートを設ける。   One set consists of a lower bracket and an upper bracket. Lightweight H steel or the like is used as the beam material. The lower bracket and the upper bracket are fixed to the appropriate height of the column, and the lower parallel part of the beam, which is arranged so that the parallel part is positioned vertically, is placed on the beam mounting part of the lower bracket and connected together. At the same time, the upper parallel portion of the beam is placed on the beam placement portion of the upper bracket to couple them together. A lower support plate is provided below the beam mounting portion of the lower bracket so as to be in contact with the outer surface of the column integrally with the lower bracket.

図1及び図2は下ブラケットを、図3及び図4は上ブラケットをそれぞれ表しており、構造物用ブラケットは、これら上下両ブラケット1,11で一組となっている。上下両ブラケット1,11は、安価で強度が高い普通鋼(例えばSS400)で成形するのが好適である。   1 and 2 show the lower bracket, and FIGS. 3 and 4 show the upper bracket. The upper and lower brackets 1 and 11 are a set of the structural brackets. The upper and lower brackets 1 and 11 are preferably formed of ordinary steel (for example, SS400) that is inexpensive and has high strength.

下ブラケット1は、支柱の外径よりも若干内径が小さい上下に貫通する支柱挿通穴2を備えている。例えば、支柱の外径が141mmである場合、支柱挿通穴2の内径は140mm程度とする。この支柱挿通穴2は、一部が外部と連通した不完全な穴である。支柱挿通穴2の内周面の適所には、該支柱挿通穴の外側構成部分を撓ませて支柱挿通穴2を拡縮させやすいように切り欠き部2a,2aが形成されている。   The lower bracket 1 includes a column insertion hole 2 penetrating in the vertical direction having an inner diameter slightly smaller than the outer diameter of the column. For example, when the outer diameter of the column is 141 mm, the inner diameter of the column insertion hole 2 is about 140 mm. This column insertion hole 2 is an incomplete hole partially communicating with the outside. Cutout portions 2a and 2a are formed at appropriate positions on the inner peripheral surface of the column insertion hole 2 so as to easily expand and contract the column insertion hole 2 by bending the outer component portion of the column insertion hole.

支柱挿通穴2の連通箇所の両側部はブロック状の拡縮具装着部3A,3Bとなっており、その拡縮具装着部3A,3Bに水平方向に貫通する拡縮具挿通穴4A,4Bが形成されている。一方の拡縮具挿通穴4Aには、後述する六角穴付き螺子31が螺合する雌ねじ4aが螺刻されている。また、他方の拡縮具挿通穴4Bの外端部には、六角穴付き螺子31の頭部が嵌合する凹部4bが形成されている。   Both side portions of the communicating portion of the support column insertion hole 2 are block-shaped expansion / contraction device mounting portions 3A and 3B, and expansion / contraction device insertion holes 4A and 4B penetrating in the horizontal direction are formed in the expansion / contraction device mounting portions 3A and 3B. ing. One expansion / contraction tool insertion hole 4A is threaded with a female screw 4a into which a hexagon socket head screw 31 described later is screwed. Moreover, the recessed part 4b with which the head of the hexagon socket head screw 31 fits is formed in the outer end part of the other expansion / contraction tool insertion hole 4B.

支柱挿通穴2を挟んで前記連通箇所と反対側は、比較的広い水平面を有する梁載置部5になっている。この梁載置部5には、互いに平行な2本の線条L1,L2に沿って2箇所ずつ計4箇所に連結具挿通穴6,…が形成されている。各連結具挿通穴6,…は線条L1,L2の方向に長い長穴になっている。   On the opposite side of the communicating portion across the support insertion hole 2 is a beam placing portion 5 having a relatively wide horizontal plane. The beam placing portion 5 is formed with connecting tool insertion holes 6,... At four places, two places along each of the two parallel strips L1, L2. Each connecting tool insertion hole 6,... Is a long hole extending in the direction of the filaments L1, L2.

梁載置部5の中央下面には、垂面7aが支柱挿通穴2の内周面から下方へ鉛直方向に延びるように、略直角三角形の下支えプレート7が溶接により固着されている。この下支えプレート7には、筋交い取付用の円形穴7bが形成されている。   A substantially right-angled triangular support plate 7 is fixed to the lower surface of the center of the beam placing portion 5 by welding so that the vertical surface 7a extends vertically downward from the inner peripheral surface of the column insertion hole 2. The lower support plate 7 is formed with a circular hole 7b for bracing attachment.

上ブラケット11は、下ブラケット1と同様に、一部が外部と連通した不完全な穴である支柱挿通穴12(支柱挿通穴2と同径)を備え、連通箇所の両側部に位置するブロック状の拡縮具装着部13A,13Bに水平方向に貫通する拡縮具挿通穴14A,14Bが形成されている。一方の拡縮具挿通穴14Aには雌ねじ14aが螺刻され、他方の拡縮具挿通穴14Bには凹部14bが形成されている。なお、上ブラケット11は、下ブラケット1よりも上下の厚みが薄いので、下ブラケット1の切り欠き部2a,2aに相当するものが形成されていない。   Similar to the lower bracket 1, the upper bracket 11 has a column insertion hole 12 (the same diameter as the column insertion hole 2) that is an incomplete hole partially communicating with the outside, and is a block located on both sides of the communication point Expansion / retraction tool insertion holes 14A and 14B penetrating in the horizontal direction are formed in the expansion / contraction tool mounting portions 13A and 13B. One expansion / contraction tool insertion hole 14A is threaded with a female screw 14a, and the other expansion / contraction tool insertion hole 14B is formed with a recess 14b. Since the upper bracket 11 is thinner than the lower bracket 1 in thickness, the upper bracket 11 is not formed corresponding to the notches 2a and 2a of the lower bracket 1.

支柱挿通穴12を挟んで前記連通箇所と反対側は、梁載置部5よりも狭い梁載置部15になっている。この梁載置部15には、下ブラケット1の内側の線条L1に沿って形成された連結具挿通穴6,6に対応する位置に、連結具挿通穴16,16が形成されている。この連結具挿通穴16も、連結具挿通穴6と同様な長穴である。   A beam mounting portion 15 narrower than the beam mounting portion 5 is formed on the side opposite to the communication portion with the column insertion hole 12 interposed therebetween. In the beam mounting portion 15, connecting tool insertion holes 16, 16 are formed at positions corresponding to the connecting tool insertion holes 6, 6 formed along the line L 1 inside the lower bracket 1. The connector insertion hole 16 is also a long hole similar to the connector insertion hole 6.

下ブラケット1及び上ブラケット11を支柱に固着するための締付具として、図5に示す六角穴付き螺子31が使用される。また、下ブラケット1及び上ブラケット11と梁とを連結するための連結具として、ボルト32及びナット33が使用される(図7に図示)。六角穴付き螺子31及びボルト32は、下ブラケット1及び上ブラケット11よりも高強度の素材、例えばクロム−モリブデン鋼のものを使用するのが好ましい。   A hexagon socket screw 31 shown in FIG. 5 is used as a fastener for fixing the lower bracket 1 and the upper bracket 11 to the column. Moreover, the bolt 32 and the nut 33 are used as a connection tool for connecting the lower bracket 1 and the upper bracket 11 and the beam (shown in FIG. 7). The hexagon socket head screw 31 and the bolt 32 are preferably made of a material having higher strength than the lower bracket 1 and the upper bracket 11, for example, chromium-molybdenum steel.

以下、上記下ブラケット1及び上ブラケット11を用いて、円筒状の支柱41に軽量H鋼製の梁42を組み付ける方法について説明する(図7参照)。支柱41としては、構造用鋼管が好適である。この支柱41の外周面所定高さの位置には、予めダボ43,…を100mm程度の間隔で溶接しておく。また、梁用の軽量H鋼としては、下ブラケット1及び上ブラケット11と同じ普通鋼が好適である。図6に示すように、梁42の平行部分の一方42aには下ブラケットの連結具挿通穴6,…に対応する連結具挿通穴44,…を、他方42bには上ブラケットの連結具挿通穴16,…に対応する連結具挿通穴45,…をそれぞれ穿設しておく。   Hereinafter, a method of assembling a lightweight H-steel beam 42 to the cylindrical column 41 using the lower bracket 1 and the upper bracket 11 will be described (see FIG. 7). As the support column 41, a structural steel pipe is suitable. The dowels 43,... Are welded in advance at a predetermined height of the outer peripheral surface of the support column 41 at intervals of about 100 mm. Further, as the light H steel for the beam, the same ordinary steel as the lower bracket 1 and the upper bracket 11 is suitable. As shown in FIG. 6, one of the parallel portions 42a of the beam 42 has a connector insertion hole 44 corresponding to the connector insertion hole 6, ... of the lower bracket, and the other 42b has a connector insertion hole of the upper bracket. ,... Corresponding to the connector insertion holes 45,.

支柱挿通穴2に支柱41を挿通させた下ブラケット1を、上記ダボ43,…に下面が当接する位置にセットする。そして、拡縮具挿通穴4B側から六角穴付き螺子31を挿入して拡縮具挿通穴4Aに螺合させ、これを六角レンチ等により締め付けて、拡縮具装着部3A,3Bを互いに接近させ支柱挿通穴2を縮径させることにより、下ブラケット1を支柱41に固着する。六角穴付き螺子31の頭部31aは凹部4bに隠れるので、邪魔にならない。同様に、支柱挿通穴12に支柱41を挿通させた上ブラケット11を、支柱41の下ブラケット11よりも所定高さだけ高い位置に固着する。   The lower bracket 1 in which the column 41 is inserted into the column insertion hole 2 is set at a position where the lower surface contacts the dowels 43. Then, the hexagon socket head screw 31 is inserted from the expansion / contraction tool insertion hole 4B side, and is screwed into the expansion / contraction tool insertion hole 4A. The lower bracket 1 is fixed to the support column 41 by reducing the diameter of the hole 2. Since the head portion 31a of the hexagon socket head screw 31 is hidden in the recess 4b, it does not get in the way. Similarly, the upper bracket 11 in which the column 41 is inserted into the column insertion hole 12 is fixed to a position higher than the lower bracket 11 of the column 41 by a predetermined height.

次いで、平行部分42aが下側、平行部分42bが上側になるように配置した梁42を、平行部分42aが下ブラケット1の梁載置部5の上に載置され、平行部分42bが上ブラケット11の梁載置部15の上に載置されるようにセットする。そして、連結具挿通穴6,…,44,…に挿通したボルト32及びこれに螺着したナット33等により、下ブラケット1と梁42とを連結するとともに、連結具挿通穴16,…,45,…に挿通したボルト32及びこれに螺着したナット33等により、上ブラケット11と梁42とを連結する。下ブラケット1及び上ブラケット11の連結具挿通穴6,16は長穴であるので、梁42の連結具挿通穴44,45の加工精度に多少難があっても、ボルト32を無理なく連結具挿通穴6,44に挿通させることができる。さらに、必要に応じて、図示しない筋交いの端部を、下ブラケット1の円形穴7bに引っ掛けて取り付ける。   Next, the beam 42 arranged so that the parallel part 42a is on the lower side and the parallel part 42b is on the upper side is placed on the beam placing part 5 of the lower bracket 1, and the parallel part 42b is the upper bracket. 11 so as to be placed on the 11 beam placing portions 15. Then, the lower bracket 1 and the beam 42 are connected by the bolt 32 inserted through the connecting tool insertion holes 6,..., 44,. ,... Are connected to the upper bracket 11 and the beam 42 by a bolt 32 inserted through the nut, a nut 33 screwed on the bolt 32, and the like. Since the connector insertion holes 6 and 16 of the lower bracket 1 and the upper bracket 11 are long holes, the bolt 32 can be connected without difficulty even if the processing accuracy of the connector insertion holes 44 and 45 of the beam 42 is somewhat difficult. The insertion holes 6 and 44 can be inserted. Furthermore, if necessary, a brace end (not shown) is attached to the circular hole 7b of the lower bracket 1 by hooking.

このようにして得られる支柱41と梁42との連結構造は、下ブラケット1及び上ブラケット11がそれぞれ個別に支柱41に固着されるとともに、下支えプレート7の垂面7aが支柱41の外面に当接して梁42の重量を支えることにより、支柱41に梁42が確実に組み付けられる。支柱41、梁42及び上下両ブラケット1,11はいずれも鋼鉄製であるため、強固な構造が得られ、しかも比較的安価に構築することができる。また、この支柱41と梁42との連結構造は、締付具31及び連結具32,33だけで構築され、基本的には溶接を行わないので、溶接の技術を会得していない作業者でも簡単に構築することができるとともに、溶接による支柱41や梁42の劣化、変質が生じないという大きな利点がある。さらに、解体後、各部材を再利用することも可能である。   The connecting structure of the support column 41 and the beam 42 obtained in this way is such that the lower bracket 1 and the upper bracket 11 are individually fixed to the support column 41, and the vertical surface 7a of the lower support plate 7 contacts the outer surface of the support column 41. By supporting the weight of the beam 42 in contact therewith, the beam 42 is securely assembled to the support column 41. Since the column 41, the beam 42, and the upper and lower brackets 1 and 11 are all made of steel, a strong structure can be obtained and the structure can be constructed at a relatively low cost. In addition, since the connection structure of the support column 41 and the beam 42 is constructed only by the fastening tool 31 and the connection tools 32 and 33 and basically does not perform welding, an operator who does not know the welding technique. However, there is a great advantage that it can be easily constructed and the column 41 and the beam 42 are not deteriorated or altered by welding. Furthermore, each member can be reused after dismantling.

梁がH鋼でない(例えばL型鋼)場合、下ブラケット1だけを使用して、支柱に梁を組み付けるようにしてもよい。   When the beam is not H steel (for example, L-shaped steel), only the lower bracket 1 may be used to assemble the beam to the support column.

下ブラケット1及び上ブラケット11の常態における支柱挿通穴2,12の内径を支柱41の外径よりも若干小さく成形する。例えば、支柱の外径が140mmである場合、支柱挿通穴2,12の内径を139.5mm程度とする。   The inner diameters of the column insertion holes 2 and 12 in the normal state of the lower bracket 1 and the upper bracket 11 are formed slightly smaller than the outer diameter of the column 41. For example, when the outer diameter of the column is 140 mm, the inner diameter of the column insertion holes 2 and 12 is set to about 139.5 mm.

この下ブラケット1及び上ブラケット11を支柱41に固着させるに際しては、予め拡縮具挿通穴4A,4B,14A,14Bに拡縮具31,31を挿通して、支柱挿通穴2,12の内径を支柱41の外径よりも広げておき、その広げた支柱挿通穴2,12に支柱41を挿通し、然る後、拡縮具挿通穴4A,4B,14A,14Bから拡縮具31,31を抜き取って、支柱挿通穴2,12を縮径させる。この方法であると、下ブラケット1及び上ブラケット11が常態で支柱41に固着しているので、その固着状態が安定するとともに、構造物の組立現場での作業工程が少なくてすみ、組立作業が簡略化できる。   When the lower bracket 1 and the upper bracket 11 are fixed to the column 41, the expansion / contraction tools 31 and 31 are inserted into the expansion / contraction tool insertion holes 4A, 4B, 14A and 14B in advance, and the inner diameter of the column insertion holes 2 and 12 is set to the column. 41, the support post 41 is inserted into the extended post insertion holes 2 and 12, and then the expansion / contraction tools 31 and 31 are removed from the expansion / contraction tool insertion holes 4A, 4B, 14A and 14B. The diameter of the column insertion holes 2 and 12 is reduced. With this method, the lower bracket 1 and the upper bracket 11 are normally fixed to the support column 41, so that the fixed state is stabilized and the number of work steps at the assembly site of the structure can be reduced, and the assembly work can be performed. It can be simplified.

本発明の構造物用ブラケットを使用した支柱と梁との連結構造は、ガレージ、バルコニー、ベランダ、ステージ、作業台などの構造物に適用できる他、既設の建物の補強にも適用できる。図8はその例で、建物50の骨格材に固定した延長梁42(A)を外壁よりも外方に突出させて設け、この延長梁42(A)と地面に立設した支柱41とを構造物用ブラケット1,11で連結し、さらに隣接する支柱41,41同士に間に架け渡した補強梁42(B)42と各支柱41とを構造物用ブラケット1,11で連結している。   The connection structure between the column and the beam using the structural bracket of the present invention can be applied to a structure such as a garage, a balcony, a veranda, a stage, and a work table, and can also be applied to reinforcement of an existing building. FIG. 8 shows an example in which an extension beam 42 (A) fixed to the frame material of the building 50 is provided so as to protrude outward from the outer wall, and the extension beam 42 (A) and a column 41 standing on the ground are provided. The structural brackets 1 and 11 are connected to each other, and the reinforcing beams 42 (B) 42 bridged between the adjacent support columns 41 and 41 and the respective support columns 41 are connected to each other with the structural brackets 1 and 11. .

また、1つの支柱挿通穴と複数の梁載置部とを備えた構造物用ブラケット60,61とすれば、1個の構造物用ブラケットで、1本の支柱41に複数本の梁42を組み付けることができる(図9参照)。さらに、上記構造物用ブラケット60,61と、梁同士を連結するブラケット62とを併用することにより、図9に示すような構造物を効率的に組み立てることができる。   In addition, if the structure brackets 60 and 61 are provided with one pillar insertion hole and a plurality of beam placement portions, one structure bracket is used to attach a plurality of beams 42 to one pillar 41. It can be assembled (see FIG. 9). Furthermore, by using the brackets for structures 60 and 61 and the bracket 62 for connecting the beams together, a structure as shown in FIG. 9 can be efficiently assembled.
