この発明は、屋根トラスその他の大スパン鉄骨
架構の横引き工法による建方の方法に関するもの
である。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for constructing roof trusses and other large-span steel frames using the horizontal construction method.
横引き工法とは、建物の一方の妻壁部分におい
てトラス等の鉄骨架構を１ユニツト（１面のトラ

すなわち所定位置まで横引き移動し、建物全体に
架構を配置し定着させる工法である（第１〜３図
参照）。 The horizontal construction method involves assembling steel frames such as trusses unit by unit (truss on one side and connecting members in the girder direction) on one end wall of a building, and sequentially connecting the entire connected frame with concrete girder beams. This is a construction method in which the first truss is moved along the rails provided above until it reaches the other end wall, that is, it is moved laterally to a predetermined position, and the frame is placed and fixed over the entire building (1 to 3). (see figure).
そして、レール上を走行させる具体的方法とし
ては、架構支承部すなわちベースプレート部分に
車輪または滑り板を取付け、これをレールまたは
レール用Ｈ型鋼の上を走行させるのである（第
４，５図参照）。 A specific method for running on rails is to attach wheels or sliding plates to the frame support, that is, the base plate, and run them on rails or H-beams for rails (see Figures 4 and 5). .

なくとも100ｍ／ｍの高さを保つよう、レールや
レール用Ｈ形鋼を高くしている。 The problem of the present invention will be explained from its background. That is, anchor bolts for fixing the base plate of the frame are planted in the concrete girders that serve as the tracks, and the heads of the bolts usually protrude above the concrete surface. Therefore, to prevent the base plate from hitting the head of the anchor bolt during horizontal pulling, the rail and H-section steel for the rail are made high enough to maintain a height of at least 100 m/m.

点があつた。 For this reason, when the frame is jacked down after horizontal pulling is completed, jacked up temporarily, and rails and wheels have been removed, the amount of downing is 100 m/
m or more, a large number of jacks must be carried out at the same time, which has the disadvantage of requiring complicated work.
本発明は、この煩雑な作業を不要とすることに

程度の低い高さで横引きし、前記した煩雑なジヤ
ツキダウンを省略するものである。 The present invention was made for the purpose of improving the efficiency of the horizontal pulling method by eliminating the need for this complicated work, and its gist is that the anchor bolt is divided into two parts: an anchor with a cap nut and a bolt part. By embedding only the anchor, obstacles during horizontal pulling are eliminated, and by using a plate laid on the concrete surface and a sliding plate attached to the underside of the base plate instead of the rail, The horizontal pulling is carried out at a low height, and the above-mentioned complicated jacking down is omitted.

はアンカープレートである。 Hereinafter, embodiments of the present invention will be described with reference to FIGS. 6 to 8 showing the order of construction. FIG. 6 shows a state in which the rail plate 2a is placed on the concrete girder 1. This cross section is particularly of the base plate attachment part, and the anchor bolt 3
The anchor 3a, which is the lower half of the anchor 3a, is buried so that the upper part of the cap nut 3c, which is fixed to the upper part, is located on the concrete surface. Code 4 in the diagram
is the anchor plate.

す。 Next, as shown in FIG. 7, the base plate 5a
The frame 5 to which the sliding plate 6 is attached is placed on the lower surface of the frame 5, and horizontal drawing is carried out in the same manner as in FIGS. 1 to 3, that is, by the conventional method. The sliding plate 6 is suitably made of Teflon or ultra-high molecular polyethylene (trademark: Himolar), and the upper surface of the rail plate is coated with oil to prevent rust and make it easy to slide. Once the frame has been moved to a predetermined position and the horizontal pulling has been completed, it is lifted by a jack (not shown) by more than 10 m/m and the rail plate 2a and sliding plate 6 are removed. and,
Loosen the jack and lower it onto the anchor plate 4.

is fixed to the concrete girder 1.
なお、袋ナツト３ｃは、アンカー埋込部に固定

利である。 Note that the shape of the cap nut 3c does not matter as long as it is fixed to the anchor embedded part and the head bolt can be screwed into it, but it is convenient to use a long nut screwed halfway into the anchor bolt and fixed by welding or the like. .

から工費と工期の節約をすることができる利点を
有する。 As described above, the present invention eliminates obstacles during horizontal pulling by dividing the anchor bolt and attaching it, and this makes it possible to move at a low position using the rail plate and sliding plate. , there is no need to operate the jacks all at once, which has the advantage of saving construction costs and construction time.
そして、すべり板に超高分子量ポリエチレンを

る。 If ultra-high molecular weight polyethylene is used for the sliding plate, it has the advantage that it is cheaper than Teflon or the like, has good wear resistance, and has practically no difference in coefficient of friction.
