Description

本発明は鋼製デッキ用取り付け治具、特に、鋼製のデッキプレート(以下、単に「鋼製デッキ」と称す)に鉄筋トラスを取り付けるための鋼製デッキ用取り付け治具に関する。   The present invention relates to a steel deck mounting jig, and more particularly to a steel deck mounting jig for mounting a reinforcing bar truss to a steel deck plate (hereinafter simply referred to as a “steel deck”).

従来、コンクリートスラブは、一般的には鋼板を波形状に成形した鋼製デッキにコンクリートが打設されるものであって、コンクリート中には補強ないし補剛のための鉄筋が配設されている。すなわち、コンクリートスラブは構造物の一方の梁と他方の梁との間に設置されるものであって、一方の梁から他方の梁に向かう方向を「スパン方向」と称すると、鋼製デッキには、スパン方向の山状部分とスパン方向の谷状部分(溝状部分)とが、スパン方向に直角な方向で交互に形成され、谷状部分の底が狭くなった略コ字状の波形を呈し、一方、鉄筋は谷状部分にスパン方向と平行に配設されている。
そして、鉄筋を鋼製デッキから浮かせて配設するためのスペーサの配設を省略して、鉄筋の配設を容易にする目的で、予め所定位置に鉄筋が固定されている鉄筋配設体を鋼製デッキに取り付ける発明が開示されている(例えば、特許文献1参照)。
Conventionally, concrete slabs are generally made by placing concrete on a steel deck formed by corrugating a steel plate, and reinforcing bars are provided in the concrete for reinforcement or stiffening. . That is, the concrete slab is installed between one beam and the other beam of the structure, and the direction from one beam to the other beam is called the “span direction”. Is a substantially U-shaped waveform in which the ridges in the span direction and the valleys (grooves) in the span direction are alternately formed in a direction perpendicular to the span direction, and the bottom of the valley is narrowed On the other hand, the reinforcing bars are arranged in the valley portion in parallel with the span direction.
Then, for the purpose of facilitating the arrangement of the reinforcing bar by omitting the arrangement of the spacer for floating the reinforcing bar from the steel deck, a reinforcing bar arrangement body in which the reinforcing bar is fixed in advance at a predetermined position is provided. An invention for attaching to a steel deck is disclosed (for example, see Patent Document 1).

実開平5−42432号公報(第4−6頁、図1)Japanese Utility Model Publication No. 5-42432 (page 4-6, FIG. 1)

特許文献1に開示された考案は、鋼製デッキが、山状部分の山頂面と谷状部分の谷底面とが平行(正確には、それぞれの面の凹凸部を除く平坦面同士が平行)で、山頂面と谷底面とを結ぶ傾斜面の谷底面に近い位置に、スパン方向の凹条が形成されている。また、主筋配設体(鉄筋配設体)は、一対のラチス状屈曲鉄筋(ジグザグに折り曲げられている)のそれぞれの全ての上端が上端筋に接合され、一対のラチス状屈曲鉄筋のそれぞれの下部に下端筋を配設したうえで、そのラチス状屈曲鉄筋のそれぞれの下端が、互いに離れる方向に折り曲げられて支承部が形成されている。   In the idea disclosed in Patent Document 1, the steel deck is such that the top surface of the mountain-shaped portion is parallel to the bottom surface of the valley-shaped portion (exactly, the flat surfaces except the uneven portions of each surface are parallel to each other). Thus, a ridge in the span direction is formed at a position close to the valley bottom surface of the inclined surface connecting the mountain top surface and the valley bottom surface. In addition, the main bar arrangement body (rebar arrangement body) is formed by joining all upper ends of a pair of lattice-shaped bending reinforcing bars (bent in a zigzag manner) to the upper end bars, After the lower end bars are disposed at the lower part, the lower ends of the lattice-shaped bending reinforcing bars are bent in directions away from each other to form support parts.

そして、主筋配設体の支承部の先端が鋼製デッキの凹条に係止するものであるところ、主筋配設体は線材によって形成され、製作誤差がある。そこで、かかる係止を容易にするために、支承部の先端の凹部への係止量(侵入深さに相当する)を小さくすると、係止が不安点になって、支承部の先端が凹部から離脱することになり、反対に、係止を確実にするために、支承部の先端の凹部への係止量(侵入深さに相当する)を大きくすると、係止させることが困難あるいは不能になるという問題があった。   And when the front-end | tip of the support part of a main reinforcement arrangement | positioning body latches to the concave strip of a steel deck, a main reinforcement arrangement | positioning body is formed with a wire, and there exists a manufacturing error. Therefore, in order to facilitate such locking, if the locking amount (corresponding to the depth of penetration) of the tip of the support portion into the recess is reduced, the locking becomes an uneasy point, and the tip of the support portion becomes the recess. On the contrary, in order to secure the locking, if the locking amount (corresponding to the penetration depth) of the tip of the support portion to the recess is increased, it is difficult or impossible to lock. There was a problem of becoming.

本発明は、前記問題を解決するものであって、鋼製デッキへの主筋配設体(鉄筋トラスに同じ)の取り付けを容易かつ確実にする鋼製デッキ用取り付け治具を提供することを目的とする。   The present invention solves the above-described problems, and an object of the present invention is to provide a steel deck mounting jig that facilitates and ensures the mounting of a main bar arrangement body (same as a reinforcing bar truss) to a steel deck.

本発明に係る鋼製デッキ用取り付け治具は、以下の効果を奏する。
(i)治具係止部と治具脚部とを有するため、鉄筋トラス(特許文献1に記載された主筋配設体に相当する)に製作誤差がある場合でも、治具係止部によって鉄筋トラスは鋼製デッキ用取り付け治具に係止し、また、治具脚部によって鋼製デッキ用取り付け治具は鋼製デッキ(鋼製デッキに相当する)に取り付けられるから、鉄筋トラスを鋼製デッキに対して所定の位置に容易かつ確実に取り付けることができる。
また、治具天面部と治具側面部とから形成された治具本体部と、治具側面部に連続した治具脚部とを有し、治具係止部が、治具切欠、側面上突起および側面下突起を具備する簡素な形状であるため、製作が容易で、製造コストが安価になる(例えば、板材を機械加工またはブランキングした後、曲げ加工する等)。
The steel deck mounting jig according to the present invention has the following effects.
(I) Since it has a jig locking part and a jig leg part, even if there is a manufacturing error in the reinforcing bar truss (corresponding to the main bar arrangement body described in Patent Document 1), the jig locking part The rebar truss is locked to the steel deck mounting jig, and the steel deck mounting jig is attached to the steel deck (corresponding to a steel deck) by the jig legs. It can be easily and reliably attached to a predetermined position with respect to the made deck.
Also, it has a jig main body formed from a jig top surface and a jig side surface, and a jig leg continuous to the jig side surface, and the jig locking portion is a jig notch, side surface Since it is a simple shape having an upper protrusion and a lower side protrusion, manufacturing is easy and manufacturing cost is low (for example, a plate material is machined or blanked and then bent).

(ii)また、治具脚部が治具本体部とは別部材によって形成されているから、製造方法(加工方法や材料選択等)の自由度が増し、製造コストがさらに安価になる。
(iii)また、治具天面部および治具側面部から形成された治具本体部と、治具側面部に連続した治具脚部とを有し、治具係止部が、治具切欠、側面上突起および側面下突起によって形成された簡素な形状であるため、製作が容易で、製造コストが安価になる(例えば、板材を機械加工またはブランキングした後、曲げ加工する等)。
(Ii) Further, since the jig leg is formed by a member different from the jig main body, the degree of freedom in the manufacturing method (processing method, material selection, etc.) is increased, and the manufacturing cost is further reduced.
(Iii) Moreover, it has the jig | tool main-body part formed from the jig | tool top surface part and the jig | tool side surface part, and the jig | limb leg part which followed the jig | tool side surface part, Since it is a simple shape formed by the upper side protrusion and the lower side protrusion, the manufacturing is easy and the manufacturing cost is low (for example, the plate material is machined or blanked and then bent).

(iv)また、治具係止部が、主筋トラスの一部が侵入する治具凹部を具備するため、製作が容易で、製造コストが安価になる(例えば、押し出し加工した後、機械加工する等)。
(v)さらに、治具係止部が、治具切欠と治具凹部とを具備するから、製作が容易で、製造コストが安価になる(例えば、押し出し加工した後、機械加工したり、単純形状の型によって鋳造したり等)。
(Iv) Further, since the jig locking portion has a jig recess into which a part of the main truss enters, the manufacturing is easy and the manufacturing cost is low (for example, after the extrusion processing, the machining is performed. etc).
(V) Furthermore, since the jig locking part includes a jig notch and a jig recess, the manufacture is easy and the manufacturing cost is low (for example, after extrusion, machining or simple Cast by shape mold).

(vi)さらに、治具脚部が、治具先端縁と治具逃げ縁とを具備するため、治具逃げ縁によって鋼製デッキ用取り付け治具の鋼製デッキへの取り付けが容易になり、治具先端縁によって鋼製デッキ用取り付け治具の鋼製デッキへの取り付けが確実になる。
(vii)そして、治具逃げ縁同士の距離が、鋼製デッキに形成された突条のうち対向する突条の先端同士の距離よりも短いため、治具逃げ縁を当該突条の先端と平行にすれば、治具先端部を鋼製デッキの谷底面に容易に押し当てることができ、治具先端縁同士の距離が、鋼製デッキに形成された凹溝のうち対向する凹溝の奥同士の距離よりも長いため、治具先端部を鋼製デッキの谷底面に押し当てながら、谷底面の法線を回転中心として回転するだけで、鋼製デッキ用取り付け治具を鋼製デッキに確実に取り付けることができる。
(ix)また、鉄筋トラスは、線材によって形成され、一対のラチス材と、一対の上弦材と、一対の下弦材とを具備するため、鉄筋トラスに製作誤差がある場合でも、下弦材は弾性変形して鋼製デッキ用取り付け治具に確実に係止する。
(Vi) Furthermore, since the jig leg has a jig tip edge and a jig escape edge, the jig escape edge facilitates the attachment of the steel deck mounting jig to the steel deck, The attachment of the steel deck mounting jig to the steel deck is ensured by the jig leading edge.
(Vii) Since the distance between the jig escape edges is shorter than the distance between the tips of the opposing ridges formed on the steel deck, the jig escape edge is defined as the tip of the ridge. If parallel, the tip of the jig can be easily pressed against the bottom surface of the trough of the steel deck, and the distance between the jig tip edges of the concave grooves formed on the steel deck is Because it is longer than the distance between the back, the steel deck mounting jig can be mounted on the steel deck simply by rotating the jig bottom against the bottom of the trough of the steel deck and rotating around the normal of the bottom of the trough. Can be securely attached.
(Ix) In addition, since the reinforcing bar truss is formed of a wire rod and includes a pair of lattice materials, a pair of upper chord members, and a pair of lower chord members, the lower chord member is elastic even if there is a manufacturing error in the reinforcing bar truss. Deforms and securely locks onto the steel deck mounting jig.

(取り付け治具の鋼製デッキへの設置要領)
図7の(a)において、取り付け治具20の治具逃げ縁29a、29bが、鋼製デッキ10の突条17b、17cの先端と平行になった状態で、取り付け治具20の治具脚部27a、27bを、鋼製デッキ10の谷底面14bに押し付ける。すなわち、治具逃げ縁29aと治具逃げ縁29bとの距離l(エル)が、突条17bと突条17cとの距離Mよりも小さくなっている(l<M)から、治具逃げ縁29a、29bは突条17b、17cの先端に干渉することはない。
(How to install the mounting jig on the steel deck)
7 (a), the jig legs of the mounting jig 20 with the jig relief edges 29a, 29b of the mounting jig 20 parallel to the tips of the protrusions 17b, 17c of the steel deck 10. The parts 27 a and 27 b are pressed against the bottom surface 14 b of the steel deck 10. That is, since the distance l (el) between the jig escape edge 29a and the jig escape edge 29b is smaller than the distance M between the protrusion 17b and the protrusion 17c (l <M), the jig escape edge 29a and 29b do not interfere with the tips of the protrusions 17b and 17c.

図7の(b)において、治具脚部27a、27bを鋼製デッキ10の谷底面14bに押し付けたまま、取り付け治具20を、谷底面14bの法線を回転中心にして回転する。この取り付け治具20の治具逃げ縁29a、29bの位置関係により、この場合はこの様な回転方向になる(治具逃げ縁29a、29bを反対位置に形成した場合には、前記とは逆回転となる)。
そうすると、取り付け治具20の治具先端縁28a、28bは、それぞれ凹溝18b、18c内に侵入し、凹溝18b、18cによって、治具脚部27aと治具脚部27b(治具先端縁28aと治具先端縁28bに同じ)とが互いに近づく方向に把持され、かつ、突条17b、17c(正確には、凹溝18b、18cを形成する突条17b、17cの下側の面)によって下方に押し付けられる。
すなわち、取り付け治具20の回転初期は、治具先端縁28aと治具逃げ縁29aとの交差部(角部)、および治具先端縁28bと治具逃げ縁29bとの交差部(角部)が、それぞれ凹溝18bおよび凹溝18cに強く当接(摺動)して、治具側面部23a、23bを弾性変形させ、さらに、取り付け治具20の回転が進んだところで、治具先端縁28a、28bと凹溝18b、18cとが平行になる。
In FIG. 7B, the mounting jig 20 is rotated around the normal line of the valley bottom surface 14 b while the jig legs 27 a and 27 b are pressed against the valley bottom surface 14 b of the steel deck 10. Due to the positional relationship between the jig relief edges 29a and 29b of the mounting jig 20, the rotation direction is in this case (if the jig relief edges 29a and 29b are formed at the opposite positions, the opposite is the case above). Rotation).
Then, the jig leading edges 28a and 28b of the mounting jig 20 enter the concave grooves 18b and 18c, respectively, and the jig leg 27a and the jig leg 27b (the jig leading edge 27c are formed by the concave grooves 18b and 18c. 28a and the jig tip edge 28b) are gripped in a direction approaching each other, and the ridges 17b and 17c (more precisely, the lower surfaces of the ridges 17b and 17c forming the concave grooves 18b and 18c) Is pushed downward.
That is, at the initial stage of rotation of the mounting jig 20, the intersection (corner part) between the jig tip edge 28a and the jig relief edge 29a, and the intersection part (corner part) between the jig tip edge 28b and the jig relief edge 29b. ) Strongly contact (slide) the concave groove 18b and the concave groove 18c, respectively, to elastically deform the jig side surface portions 23a, 23b, and when the rotation of the mounting jig 20 proceeds, The edges 28a, 28b and the grooves 18b, 18c are parallel to each other.

このとき、治具先端縁28aと治具先端縁28bとの距離L(図1の(b)参照)が、凹溝18bの奥(凹溝18bを形成する突条17bの下面と谷底面14bとが交差する部分に相当する)と凹溝18cの奥(凹溝18cを形成する突条17cの下面と谷底面14bとが交差する部分に相当する)との距離Nよりも長くなっている(L>N)から、治具側面部23a、23bの弾性変形量は減少するものの、依然、弾性変形した状態であるから、前記のように、取り付け治具20の治具先端縁28a、28bは、凹溝18b、18cによって把持される。
したがって、取り付け治具20は、簡単な操作によって、鋼製デッキ10と確実に当接し、互いに力を受け渡すことができる状態になっている。
At this time, the distance L (see FIG. 1B) between the jig tip edge 28a and the jig tip edge 28b is the depth of the groove 18b (the lower surface of the protrusion 17b forming the groove 18b and the valley bottom surface 14b). And a depth N of the groove 18c (corresponding to a portion where the lower surface of the protrusion 17c forming the groove 18c and the valley bottom surface 14b intersect) is longer than a distance N. From (L> N), the amount of elastic deformation of the jig side surface portions 23a, 23b is reduced, but is still elastically deformed, and as described above, the jig tip edges 28a, 28b of the mounting jig 20 are. Is held by the grooves 18b and 18c.
Therefore, the mounting jig 20 is in a state in which it can be surely brought into contact with the steel deck 10 by a simple operation and can pass the force to each other.

(鉄筋トラスの取り付け治具への取り付け要領)

そうすると、下弦材60aは側面上突起24aの下側縁と側面下突起26aの上側縁との間に侵入して、治具側面部23aに当接し、下弦材60bは側面上突起24bの下側縁と側面下突起26bの上側縁との間に侵入して、治具側面部23bに当接する。すなわち、下弦材60a、60bは弾性変形した状態で、治具側面部23a、23bを互いに近づく方向に把持している。
したがって、鉄筋トラス30は、簡単な操作によって、取り付け治具20と確実に当接し、鋼製デッキ10との間で互いに力を受け渡すことができる状態になっている。
(How to attach the rebar truss to the mounting jig)
In FIG. 8, a reinforcing bar truss 30 is attached to an attachment jig 20 installed on a steel deck 10 (not shown).
That is, the lower chord material 60a and the lower chord material 60b of the reinforcing bar truss 30 are separated from each other to increase the distance between them (enlarging the substantially V-shaped opening angle). The lower chord material 60b is disposed between the upper edge of the side lower protrusion 26a, and the lower chord material 60b is disposed between the lower edge of the side upper protrusion 24b and the upper edge of the side lower protrusion 26b, and then the lower chord material 60a and the lower chord material 60b. Is removed and elastically restored to narrow the distance between them.
Then, the lower chord material 60a enters between the lower side edge of the side surface upper protrusion 24a and the upper edge of the side surface lower protrusion 26a and comes into contact with the jig side surface portion 23a, and the lower chord material 60b is below the side surface upper protrusion 24b. It penetrates between the edge and the upper edge of the side lower projection 26b, and comes into contact with the jig side surface portion 23b. That is, the lower chord members 60a and 60b are gripped in the direction in which the jig side surfaces 23a and 23b approach each other while being elastically deformed.
Therefore, the rebar truss 30 is in a state in which it can be surely brought into contact with the mounting jig 20 by a simple operation and can exchange a force with the steel deck 10.
