Detailed description of the invention
As shown in Figure 1, 2, 3, the present invention includes the elongated bar in an ear seat fixed link 1, two centres 2, regulating rod 3 and three groups of detouchable joints 4 of coaxial setting.
The first otic placode 1-1 is fixedly connected with in ear seat fixed link 1 one end; At the other end of ear seat fixed link 1, two groups of horizontal pin-and-hole 1-2 are set along the length direction of ear seat fixed link 1.
The two ends of each elongated bar 2 in centre arrange two groups of horizontal pin-and-hole 2-1 respectively at length direction.
Regulating rod 3 comprises quarter butt 3-1, the second otic placode 3-2, connecting screw rod 3-3, the first nut (thread rotary orientation: left) 3-4 and the second nut (thread rotary orientation: a right) 3-5.One end of quarter butt 3-1 is fixedly connected with the first nut 3-4, one end of second otic placode 3-2 is fixedly connected with the second nut 3-5, the two ends of connecting screw rod 3-3 arrange left and right screw thread respectively, and the two ends of connecting screw rod 3-3 screw respectively on the first nut 3-4 and the second nut 3-5.Loosening in order to prevent from being threaded, the connecting screw rod 3-3 of the present invention also outside the first nut 3-4 and the second nut 3-5 is threaded respectively two fastening screw nut 3-7 and 3-8.The other end of quarter butt 3-1, two groups of pin-and-hole 3-6 are set along the length direction of quarter butt 3-1.
Rectangle is respectively with the cross-sectional plane of the quarter butt 3-1 of upper ear seat fixed link 1, middle elongated bar 2 and regulating rod 3.
The cylindrical shell of each group of detouchable joint 4 to be cross sections be rectangle, at the two ends of cylindrical shell, arranges horizontal pin-and-hole 4-1 and 4-2 of at least two groups along barrel lenght direction.As shown in Figure 2.
Ear seat fixed link 1, middle elongated bar 2 and quarter butt 3-1 order arrangement successively, and adjacent between be coaxially nested with by three groups of detouchable joints 4, by the pin-and-hole central alignment on the pin-and-hole on each and detouchable joint 4, then penetrate connecting pin 5 and connect (see Fig. 1, Fig. 5).
The present invention can realize regulating rod 3 by detouchable joint 4 and bearing pin 5 and directly be connected (see Fig. 4) with ear seat fixed link 1, also can connect, change the elongated bar 2(in centre of different length between see Fig. 1).Can random length be combined into, reach the adjustment of large scale attached wall strut.And by the left and right threaded engagement annexation of connecting screw rod and the first nut, the second nut, the fine setting of attached wall strut in length can also be reached.Like this, just make the present invention adapt to and meet the demand of use.The present invention is applicable to each building site and uses (without the need to for specializing in or change a social system in a certain building site), is applicable to Multiple Type tower machine and uses (without the need to specializing in for certain type tower machine or change a social system).Greatly can save material, also the adjustment at convenient construction scene.
Using method: by the tower machine attached wall requirement of engineering that will use tower machine modularized combination type attached wall strut, determine the overall length of each attached wall strut, then the ear seat fixed link 1 of different length, middle 1 ~ 2, elongated bar is selected, regulating rod 1 adds detachable connector 2 ~ 3 and is coaxially nested with assembling, by the pin-and-hole on rod member and the pin-and-hole central alignment on joint, with bearing pin, they being fixedly connected with can (see Fig. 1).
Shorter attached wall strut directly can add detachable connector 1 with 1 ear seat fixed link and 1 regulating rod and coaxially be nested with assembling, and by the pin-and-hole on rod member and the pin-and-hole central alignment on joint, same bearing pin is fixedly connected with them and gets final product (see Fig. 4).
Because regulating rod is fine-tuning, pre-determined attached wall strut overall length will always in the adjustable length range of the attached wall strut combined.
During attached wall, insert pinned connection by behind the earhole alignment hole center on the earhole on the first otic placode of each attached wall strut single-piece assembled and the attached wall frame on tower machine fuselage, the earhole on the second otic placode of each single-piece and the pre-buried ear seat (with otic placode and lug plate holes) be embedded on building also use pinned connection after the central alignment of hole.The squareness of the tower machine after attached wall can also be adjusted by finely tuning.As shown in Figure 5.
