The specific embodiment
Below in conjunction with drawings and Examples, the specific embodiment of the present utility model is described in further detail.Following examples are used to illustrate the utility model, but are not used for limiting scope of the present utility model.
As depicted in figs. 1 and 2, the utility model vertical transfer hinge system of being used for rib structure comprises support leg 2, hinge 3, free bearing 4, padlock 5 and block 6.Support leg 2 is the syndeton of rib structure and hinge 3, by support leg 2 rib structure is bearing on the hinge 3; Hinge 3 is placed in the free bearing 4, the revolving member of hinge 3 during as vertical transfer; Free bearing 4 is fixed on the abut 1; Padlock 5 latches on the hinge 3, and padlock 5 inside have and the adaptive groove of hinge 3 external surfaces, and its bottom is fixed on the abut 1; Block 6 is arranged on an end of hinge 3, and is fixed on the abut 1.
Particularly, the axis normal of hinge 3 is in the vertical transfer plane at vertical transfer hinge system place, promptly perpendicular to the vertical facade of circuit, to guarantee carrying out smoothly of vertical transfer.Hinge 3 can be set to the cylindrical steel tubular structure, closed at both ends, and inner fill concrete is to strengthen its rigidity.
General single abut arch rib steel structure generally is divided into inside and outside two when vertical transfer is constructed, in the support leg of interior outer plate arch rib is arranged on separately in the plane of outer plate arch rib, the support leg upper extreme point of interior outer plate arch rib is in arch rib plane internal coordinate unanimity, lower extreme point then is the intersection point of arch rib plane, the interior outside and vertical transfer hinge line, and this line of 2 is the axis direction of support leg.For parallel rib structure, the support leg structure of interior outer plate arch rib is in full accord, and for hand basket type rib structure, the interior outer plate rib structure except that the support leg is in full accord, so just facilitates and simplifies the prefabricated and pre-assembly location of factory greatly.Only need during installation can make parallel arch rib tilt to be supported on the horizontal hinge shaft with angle, realize the hand basket arch structure by length according to side stay leg inside and outside the shape adjustments of pre-assembly.Thus, rib structure, support leg 2 and hinge 3 link into an integrated entity the revolving member during as vertical transfer.
Wherein, support leg 2 adopts the steel box structure, and the one end can be connected with rib structure by welding or bolt mode, and the other end is welded on the hinge 3.Particularly, many group support legs 2 can be set in the above according to the length of hinge 3, support leg 2 can be set to V-arrangement, with the supporting arch rib structure.
As shown in Figure 3 and Figure 4, free bearing 4 is a steel work, mainly is made of semi arch plate 7, base plate 8 and base plate 9, and hinge 3 is placed in the semi arch plate 7, hinge 3 can slide in semi arch plate 7, the frictional resistance of filling greasing substance when reducing to relatively rotate between hinge 3 and the semi arch plate 7.Base plate 8 is vertically installed between semi arch plate 7 and the base plate 9, and semi arch plate 7 is bearing on the base plate 9, and base plate 9 is fixed on the abut 1 by bottom surface welding anchor bar 11 and installation stone bolt 10.Base plate 9 is provided with certain inclination angle with horizontal plane, and the resultant direction that makes each state in the whole vertical transfer process and free bearing 4 vertical line sail angles front and back are about equally.
Padlock 5 fastens hinge 3, directly is anchored on the abut 1, skids off to prevent that hinge 3 meets accident in the vertical transfer process, strengthens the safety of vertical transfer.As shown in Figure 5 and Figure 6, the contact surface of padlock 5 and hinge 3 is set to the shape of hinge 3 suitable, and padlock 5 directly is anchored on the abut 1 by stone bolt 10.In actual application, a plurality of padlocks 5 can be set in the above according to the length of hinge 3.Block 6 adopts concrete component, be arranged on hinge 3 one ends, be fixed on the abut 1, lateral force that the opposing rib structure transmits and the lateral displacement that limits hinge 3, block 6 is provided with hinge 3 one end in contact faces and contacts steel plate 12, the frictional force of filling greasing substance when reducing to rotate, contact steel plate 12 is fixed in the block 6 by the anchor bar at the steel plate back side.
In the present embodiment, hinge 3 is consolidated with rib structure by support leg 2, is positioned in the free bearing 4, and free bearing 4 is fixed on the concrete surface of abut 1, realizes the vertical transfer of whole rib structure by the slip of hinge 3 in free bearing 4.Free bearing 4 is as the important primary structure member of vertical transfer, by the anchor bar 11 of base plate 9 welding and pre-buried stone bolt 10 and firm the combining of abut concrete, can well bear stressed in the vertical transfer process.In addition, the lateral force of bearing rib structure at free bearing 4 arranged outside blocks 6, and at the block 6 and the contact surface of hinge 3 stainless steel is set and contacts steel plate 12 and reduce friction makes free bearing 4 only bear power in the vertical transfer plane, effectively guarantees the safety of free bearing structure.And be arranged on hinge 3 outer padlocks 5 and directly be anchored on the abut 1, to increase the safety of structure by stone bolt.
The vertical transfer hinge system that is used for rib structure that the utility model provides, simple structure, power transmission is clear and definite, safe and reliable, both be applicable to parallel rib structure, also be applicable to hand basket type rib structure, vertical transfer to arch rib has extensive applicability, can effectively satisfy the requirement of arch rib vertical transfer construction to the vertical transfer hinge, make the vertical transfer process safer, reliable, facilitation is played in the further application on arch rib construction method to the vertical transfer method.
The above only is a preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model know-why; can also make some improvement and replacement, these improvement and replacement also should be considered as protection domain of the present utility model.
