(5) specific embodiment
Embodiment is referring to Fig. 1, and is shown in Figure 2, and this highrise building elevator hoistways template supports special-purpose from the clamping type platform, comprises the scaffold floor 4 that places the supporting frame in the elevator hoistways and be connected in the supporting frame upper surface, it is characterized in that the structure of supporting frame is:
Following little cross bar 12 by the last little cross bar 6 of two parallel last legers 5, three levels, two parallel following legers 11, three levels joins into three-dimensional frame structure with six roots of sensation vertical rod 7, wherein three last little cross bars 6 are connected to two both ends and middle parts of going up leger 5, wherein three down little cross bar 12 be connected to the both ends and the middle parts of two following legers 11, six roots of sensation vertical rod 7 is connected with the middle part with an end of going up a leger 5 and a following leger 11 of homonymy respectively.
Other has the main stress brace 1 of two opposing parallel to fixedly connected with above-mentioned three-dimensional framework, the upper end of two main stress braces 1 and 6 liang of last little cross bars on leaning against elevator shaft hole 9 opposite elevator hoistways sidewalls are located to join node and are fixedlyed connected, fixedly connected with vertical rod 7 handing-over node places with two following leger 11 middle parts respectively in the middle part of two main stress braces 1, elevator shaft hole 9 is passed in the lower end of two main stress braces 1, be supported on the floor in 9 outsides, elevator shaft hole, be close to the main stress little cross bar 2 of 9 inner wall positions fixedly connected length in elevator shaft hole between two main stress braces 1 greater than elevator shaft hole 9 width.Be close to the Insurance riders little cross bar 3 of 9 outer wall positions fixedly connected length in elevator shaft hole between above-mentioned two main stress braces 1 greater than elevator shaft hole 9 width.
Supporting frame can adopt the steel tube fastener assembling, can also use the shaped steel welding fabrication.
For lifting by crane conveniently, be connected with suspension hook on the above-mentioned supporting frame.
Referring to Fig. 3-Fig. 5, supporting frame is installed in the elevator shaft 8, in scaffold floor 4 upper supports elevator tube mould 10 is arranged.Elevator shaft 8 wherein on a sidewall elevator shaft hole 9 is arranged.
For further strengthening the rigidity of supporting frame, can reinforce with encrypting brace or bracing piece between each rod member of above-mentioned supporting frame.For example, one or two main stress braces can be increased between above-mentioned two main stress braces, also bracing piece can be connected between two main stress braces and the two following legers.
In practice, because main stress brace 1 is main stressed member,, be beneficial to the simplification computation model so main stress brace 1 touchdown point apart from doorway cross bar horizontal range unsuitable long (≤200), when distance is short and small, when doing Force Calculation, can not considered this section.The angle of inclination of main stress brace 1 should in the light of actual conditions be set up, and convenient should guarantee to promote in the future the time.
Two main stress braces 1 in the supporting frame are mainly stressed and decompose the member of Vertical Load, excessive and elevator cylinder size changes when excessive when load, can be on demand add bar in the vertical direction of main stress brace 1, and get in touch whole with supporting frame, can reach like this increases main stress brace 1 radius of gyration, reduce the purpose of slenderness ratio, also can improve bearing capacity simultaneously.
In order to improve main stress brace 1 bearing capacity, can increase corresponding shortly tiltedly do by this node, reducing the effective span of brace, and the part Vertical Load is delivered on the shear wall.When long and short brace angle is very reasonable, these two rod members will become the axial compression rod member, thereby avoid rod member to be cut, bent.Rod member actual set up the conduction sequence unanimity of order power should be with force analysis the time, to guarantee the accuracy of computation model.The supporting frame top platform leans firmly horizontal extent planted agent and elevator shaft 8 walls, to guarantee its stability.Main stress brace 1 is the most important power of holding rod member, and is main stressed based on press-bending, should suitably encrypt brace or the method taking to dwindle calculated length is guaranteed safety and stability according to the variation of load and the standard width of a room in an old-style house size during use.For guaranteeing the stability of supporting frame, supporting frame is encorbelmented partly suitable long (≤200), if be necessary also can increase oblique waist rod member.Owing to be subjected to the restriction of gate size, must form both sides and the stressed state of encorbelmenting occur, to encorbelment when being controlled in the 300mm from present mode of occupation, structure is stable, if greater than 300mm, the method that should calculate and take to add oblique fulcrum bar separately solves.Setting up of this platform should suitably be adjusted according to each engineering site actual conditions, to guarantee its safety, stable, characteristics easily.
