Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is further illustrated.
As shown in Figure 1 and Figure 2, construction of lift well derrick of the present utility model, comprise knighthead 1, vertical supporting rod and construction operation platform, the bottom of described knighthead 1 is plugged in elevator door hole 18 or spliced eye reserved by the borehole wall, the top of knighthead 1 rests against on the borehole wall of side, opposite, the lower end of described vertical supporting rod is connected with knighthead 1, and the top of vertical supporting rod is provided with described construction operation platform.
This construction of lift well derrick is basic as load by the knighthead 1 that elevator door hole 18 is inserted in bottom, top leans on opposite sidewall, connect vertical supporting rod thereon, vertical supporting rod arranges construction operation platform and just can complete setting up whole derrick, according to actual conditions, also spliced eye can be reserved at the elevator shaft borehole wall, for the grafting of knighthead 1, and the size of the concrete each component of derrick can be determined according to the real size of elevator shaft.When building construction operation platform, platform can be made substantially to cover hoistway, thus improve the safety of construction.Because whole derrick leans on knighthead 1 as brace foundation, after elevator shaft one deck construction casting concrete completes, next construction layer will be hung by tower crane and install and use, and without the need to again setting up in addition.
Concrete quantity and the arrangement of knighthead 1 and vertical supporting rod can be determined according to actual conditions, and as a kind of preferred embodiment, both sides are respectively furnished with two described knightheads 1, described vertical supporting rod comprises two long support montants 3 and two short vertical supporting rods 4, described two long support montants 3 are connected to the bottom of the knighthead 1 of both sides, described two short vertical supporting rods 4 are connected to the top of the knighthead 1 of both sides, and described each long support montant 3 and each short vertical supporting rod 4 are arranged between two knightheads 1 of homonymy respectively.
Wherein both sides are respectively furnished with the stability that two knightheads 1 can ensure load, and two long two short totally four vertical supporting rods can be convenient to setting up of top construction operation platform.As shown in Figure 1, between two knightheads 1 vertical supporting rod being arranged at respectively homonymy, the stability connected can be ensured.
For ensureing stablizing of vertical supporting rod lower end and stablizing of being connected with knighthead 1 thereof, as preferred embodiment, described long support montant 3 is provided with transverse horizontal bar 5 with knighthead 1 connection and short vertical supporting rod 4 with knighthead 1 junction, described short vertical supporting rod 4 is also provided with vertical equity bar 6 with knighthead 1 connection, described vertical equity bar 6 extends and is connected with long support montant 3, described vertical equity bar 6 is also provided with transverse horizontal bar 5 with long support montant 3 connection, described each transverse horizontal bar 5 is perpendicular with knighthead 1, described vertical equity bar 6 is perpendicular with transverse horizontal bar 5.
By the reinforcement by connection of vertical equity bar 6 and transverse horizontal bar 5, thus improve the stability of support bottom.Can find out, longitudinal direction is here actual be consistent with the horizontal-extending direction of knighthead 1, horizontal then be direction perpendicular with knighthead 1 in the horizontal plane.
Equally, for ensureing that knighthead 1 bottom is stablized, not easily because of stressed occurred level Slip Deformation, as preferred embodiment, the bottom of described each knighthead 1 is connected with fixed transverse rod 2, and described fixed transverse rod 2 is connected with each knighthead 1 is vertical.
As mentioned before, the derrick provided in view of the utility model adopts the mode of lifting to shift construction, for ease of the carrying out of lifting, preferred elevator shaft adopts form of construction work from top to bottom, after transfer construction, when lower floor carries out pouring construction, attended operation is carried out, for convenience of this operation, as preferred embodiment bottom the collar tie beam need built last layer, described construction operation platform comprises upper platform and lower floor's platform, and described upper platform area is less than lower floor's platform.
Wherein, the collar tie beam that upper platform is mainly used in last layer has been built carries out construction maintenance, and lower floor's platform is mainly used in building this layer of collar tie beam.Constructor needs to shift up and down between two-layer platform, and therefore, while lower floor's platform substantially covers hoistway thus ensures safety, upper platform is smaller, so that the lifting of redundant labor transfer and derrick.
Upper and lower two-layer platform concrete structure can refer to general putting up platform, and providing a kind of preferred embodiment set up at this: described lower floor platform comprises at least two lower floor's platform cross bars 7 arranged in parallel and at least two lower floor's platform vertical poles 8 arranged in parallel, described lower floor platform cross bar 7 is perpendicular with knighthead 1, described lower floor platform vertical pole 8 is perpendicular with lower floor's platform cross bar 7, and described lower floor platform cross bar 7 and lower floor's platform vertical pole 8 are equipped with lower floor's landing slab 9; Described upper platform comprises at least two upper platform cross bars 10 arranged in parallel and at least two upper platform vertical poles 11 arranged in parallel, described upper platform cross bar 10 is perpendicular with knighthead 1, described upper platform vertical pole 11 is perpendicular with upper platform cross bar 10, and described upper platform cross bar 10 and upper platform vertical pole 11 are equipped with upper platform plate 12.That is, adopt platform bar composition platform skeleton in length and breadth, then lay landing slab thereon and can complete setting up of platform.As shown in Figure 2, wherein lower floor's platform have employed four platform vertical poles and four platform cross bars, wherein two platform vertical poles are connected with four vertical supporting rods respectively with two platform cross bars, with stabilized platform basis, and upper platform is primarily of three platform cross bars and two platform vertical pole compositions, two platform vertical poles are connected with vertical supporting rod, and three platform cross bar uniform spreadings are located on platform vertical pole, because these three platform cross bars are not directly connected with vertical supporting rod, in order to ensure stablizing in integral frame upper lateral, the reinforcing transverse bar 13 that two connect vertical supporting rods is being added especially in the bottom of upper platform.
Because derrick preferably adopts lifting form to shift, for convenience of lifting, as preferred embodiment, described lower floor platform is installed with hole for hoist, during lifting, hole for hoist is connected with lifting steel cable 14, and the suspension centre 15 of lifting steel cable is positioned on longitudinal bisector 17 of hoistway cross section, and be positioned at the vertical central point 16 of hoistway and be partial to side, knighthead 1 bottom, the distance d between suspension centre 15 and hoistway longitudinal center's point 16 is 30cm-50cm.
Reserve hole for hoist at lower floor's platform to lift to facilitate connection lifting steel cable 14, and when lifting, the selection of the suspension centre 15 of steel cable is comparatively exquisite, as depicted in figs. 1 and 2, suspension centre 15 is selected on longitudinal bisector 17, during to ensure lifting, the balance of derrick transverse direction, require that suspension centre 15 is partial to 30cm-50cm place, side, knighthead 1 bottom at the vertical central point 16 of hoistway simultaneously, so, when lifting by crane, constructor stands on derrick and the lower end of knighthead 1 can be extracted once pushing away gently, and when behind arrival precalculated position, slowly let go and knighthead 1 just can be made to insert predetermined position, so make whole lifting transfer process very convenient.
