The specific embodiment
By reference to the accompanying drawings, preferred embodiment of the present invention is described in further details.
Openable moulding bed among the present invention referring to Fig. 1 to Fig. 3, comprises moulding bed pedestal 1 and at least two pairs of opening frames 2, is provided with 4 pairs in the present embodiment, and every pair of opening frame comprises left side opening frame 21 and the right side opening frame 22 of symmetrical configuration.
Arrangement for adjusting height 3 comprises two fixing chuck plates 31, bearing pin 32 in conjunction with Figure 11.Two fixing chuck plates 31 adopt angle steel, and parallel with middle vertical rod 13, solid welding is between upper beam 14 and cross member 11.Offer respectively some pin shaft holes 33 of vertical arrangement on the fixing chuck plate 31, bearing pin 32 two ends are inserted in the pin shaft hole 33, and setting is the level of state.Removable longeron 15 is parallel with bottom girder 12, and two ends are shelved on respectively to form on the bearing pin 32 and install.
Left side opening frame 21 is installed in respectively on the different cross member 11 with right side opening frame 22, because both symmetrical configuration are launched to describe with regard to one of them left side opening frame 21 here.
Left side opening frame 21 comprises that mainly the side rod 211 that lays respectively at both sides, cross bar 212 and a left side that is connected between the side rod 211 close up end plate 213.The bottom of side rod 211 is installed on cross member 11 by hinge, so that left side opening frame 21 can rotate around tie point.The bottom of side rod 211 and the part shape that exceeds upper beam 14 are in an angle, specifically exceed the part of upper beam 14 to moulding bed pedestal 1 interior lateral buckling, when left side opening frame 21 and right side opening frame 22 close up, form the structure of an isosceles triangle like this.Spacing between two side rods 211 diminishes from below to up gradually simultaneously, is similar to ladder.Connect a left side at the top of side rod 211 and close up end plate 213, close up end plate 223 and on right side opening frame 22, equally also be provided with the right side, after a left side closes up end plate 213 and the right side and closes up end plate 223 and fit, be connected and fixed by securing members such as bolts.
After a left side closes up end plate 213 and the right side and closes up end plate 223 and be connected and fixed, the jack 6 that is carried as 5T is installed in its bottom.
When opening, have one fixed width in order to ensure left side opening frame 21 and limit, adopt U-shaped connector 4 that left side opening frame 21 is connected with upper beam in the present embodiment and connect.The U-shaped chamber cover of U-shaped connector 4 is therein on cross bar 212, and then the peristome of U-shaped connector 4 is connected the formation rotation with a rotating shaft on the upper beam 14.When left side opening frame 21 is opened, by U-shaped connector 4 it is caught on spacingly, it is excessive to be unlikely to open degree.The opening frame 22 same modes of same principle that adopt in right side connect by U-shaped connector 4.The state of opening can be in conjunction with shown in Figure 13.
In addition, the firmness during in order to ensure left side opening frame 21 closure is equipped with stopping means 5 between left side opening frame 21 and upper beam 14.Stopping means 5 mainly comprises limiting plate 51, location-plate 52, and the bolt 53 that connects both.Limiting plate 51 is fixed on the side rod 211, and location-plate 52 is fixed on the upper beam 14 simultaneously.Limiting plate 51 and location-plate 52 all offer bolt hole, and bolt 53 passes two bolts hole limiting plate 51, location-plate 52 are realized connecting.The opening frame 22 same modes of same principle that adopt in right side connect spacing by stopping means 5.
The job practices that adopts above-mentioned openable moulding bed to carry out the triangular truss assembly unit in conjunction with Fig. 4 to Figure 10, comprises the following steps:
The first step at first can be installed moulding bed pedestal 1, left side opening frame 21 and the right side opening frame 22 of openable moulding bed according to the structure of Fig. 1 to Fig. 3, and U-shaped connector 4 and stopping means 5 are installed simultaneously, and left side opening frame and right side opening frame are open state.
Second step utilizes arrangement for adjusting height 3 to be adjusted to predetermined assembly unit height removable longeron 15, with upper chord 81 be placed on the removable longeron 15 docking finish in place, such as Fig. 4.Can limited block and cushion block be set at removable longeron 15, regulate the position of upper chord 81.
The 3rd step is good with web member 82 assembly units between the upper chord 81 on the openable moulding bed, such as Fig. 5.
The 4th step lifted lower chord 83 to the openable moulding bed, then closed up left and right sides opening frame 21,22, a left side is closed up end plate 213 and the right side close up end plate 223 and be connected and fixed.The mode of closing up can adopt wire rope in both sides left and right sides opening frame 21,22 to be drawn close to the centre, closing up end plate 213 and the right side until top left closes up and naturally closes up after end plate 223 enters the angle steel chute aloft, a left side being closed up end plate 213 and the right side closes up end plate 223 and uses bolt tightening again, prevent its slip, referring to Fig. 6, then lock stopping means 5.
The 5th step, close up end plate 213 on a left side and rightly close up end plate and hang the jack 6 that is carried as 5T for 223 times, lower chord 83 usefulness jacks 6 are mentioned, and adjust the position of lower chord 83, make its with assembly unit sampling point overlap, as shown in Figure 7.In order to prevent that lower chord 83 positions change in subsequent installation, increase the jack 6 that is hung on left side opening frame 21, the right side opening frame 22, is carried as 2T in lower chord 83 both sides, in conjunction with Figure 12.Such three tie points have been guaranteed the registration of lower chord 83.
In the 6th step, the diagonal web member 84 between assembly unit upper chord 81 and the lower chord 83 is in conjunction with Fig. 8.Can hang temporary operating platform with regard near position on both sides opening frame 2 during the chord member node installation, the assembly unit personnel are in place with lower edge web member node on operating platform, because the lower-chord panel point position is less, need the time of work high above the ground relative with the position less.
In the 7th step, after welding is finished, unclamp a left side and close up end plate 213 and the right bolt that closes up on end plate 223 and the stopping means 5, remove jack 6, open left side opening frame 21 and right side opening frame 22, as shown in Figure 9, with 7 tread flakings of triangular truss as shown in figure 10 that weld, prepare next Pin of assembly unit.
Above-described embodiment only is used for explaining inventive concept of the present invention, but not to the restriction of rights protection of the present invention, allly utilizes this design that the present invention is carried out the change of unsubstantiality, all should fall into protection scope of the present invention.
