Description
Technical field
The invention belongs to construction engineering technical field, be specifically related to the extensible canopy of elevator shaft class bobbin type cast-in-place shear wall construction template platform.
Background technology
In building operations, often run into the bobbin type cast-in-place shear wall of various shape and different cross section size, as elevator shaft class bobbin type cast-in-place shear wall, need at bobbin inside overlap joint template platform during installation form, more common method adopts steel pipe, fastener, plank etc. to overlap, this traditional bridging method, consumptive material is many, time-consuming, and the cast-in-place shear wall of difformity and sectional dimension needs the overlap joint component of different size and quantity, not only cost is high, and workload is large, and the simple platform built exists very large potential safety hazard.
Summary of the invention
Technical problem to be solved by this invention is: solve above-mentioned prior art Problems existing, and a kind of hoistway formwork platform extensible canopy is provided, be applied to hoistway formwork platform, the length of beam can not only be regulated arbitrarily within the specific limits, adapt to the bobbin type cast-in-place shear wall construction of difformity and sectional dimension, and can promote in elevator shaft, every layer of strong fix pin, maneuverability, improve building operations efficiency, reduce cost of manufacture, use manpower and material resources sparingly, and reusable, safety factor is high.
The technical solution used in the present invention is:
A kind of hoistway formwork platform extensible canopy, comprises clamped beam, regulates beam and be arranged on the self-return ratchet regulating beam one end; Described clamped beam is welded by channel-section steel and i iron, by two channel-section steels, interval, centre Plate Welding are formed by connecting described adjustment beam back-to-back, the i iron of clamped beam one end is sleeved between two channel-section steels of adjustment beam, lower lock block one is welded on and regulates bottom beam, upper holder block one is locked at bolt assembly and regulates back portion, upper holder block dual-purpose bolt assembly is locked at the i iron top of clamped beam, and lower lock block dual-purpose bolt assembly is locked at bottom the i iron of clamped beam; Described self-return ratchet comprises riser and is arranged on balancing weight and the roller at riser two ends respectively, is connected in the middle part of riser by Assembly of pin with the adjustment beam of extensible canopy end.
In technique scheme, the i iron of described clamped beam is welded with deep floor.
In technique scheme, described self-return ratchet is four, lays respectively at the two ends of two extensible canopies.
In technique scheme, described balancing weight is provided with screwed hole, and adjusting bolt is arranged in the screwed hole of balancing weight.
In technique scheme, described riser is provided with sole bottom roller one end.
In technique scheme, described riser is made up of two block plates, is connected with stiffener between two block plates.
Unclamp the bolt assembly of upper holder block one and upper holder block two, regulate beam can move along the i iron of clamped beam, thus regulate the length of extensible canopy, after being adjusted to Len req, the bolt assembly of locking upper holder block one and upper holder block two.Then according to the bobbin type cast-in-place shear wall of different cross sectional shapes and sectional dimension, select different length and the wooden H-beam of quantity and the plank of different size and quantity, be joined with bolts on extensible canopy, be overlapped to form a safe and reliable hoistway formwork platform.
Hoistway formwork platform extensible canopy of the present invention, structure is simple, and cost of manufacture is low, can regulate arbitrarily the length of beam within the specific limits, easy to adjust, and can reuse, for building template platform, make template platform size adjustable, adapt to different cross section size bobbin type cast-in-place shear wall template construction, processing ease, safe and reliable, greatly save manpower and materials.Particularly the present invention to install a kind of reusable at extensible canopy two ends, promotes and can stablize the self-return ratchet of pin, for template platform, solves the promoting of template platform dexterously, pin problem.This self-return ratchet, and can be rotated within the scope of certain angle around bearing pin by the extensible canopy two ends of pinned connection at template platform by riser, and in a free state, self-return ratchet, under the effect of balancing weight, turns clockwise around bearing pin.Suitable adjusting bolt, when adjusting bolt lower end contacts with the location-plate on template platform extensible canopy, self-return ratchet is the level of state.
During building operations, template platform is carried by crane gear on the whole, self-return ratchet is rotated counterclockwise adduction around bearing pin, the roller of riser one end rolls along bobbin inwall, and when reaching the pre-buried cover on second layer bobbin inwall body of wall, self-return ratchet is under the effect of balancing weight, automatically turn clockwise return, horizontal, self-return ratchet one end falls in pre-buried cover, makes template platform firmly be overlapped in second layer bobbin; Be promoted to third layer again after the second layer completes, so analogize, a set of equipment can complete the construction of entire building elevator shaft class bobbin type cast-in-place shear wall.
The present invention can realize the adjustment of template platform planar dimension size, adapt to the needs that different size size elevator shaft class bobbin type cast-in-place shear wall builds template platform, template platform can be realized again in the pre-buried cover of bobbin type cast-in-place shear wall, accurately automatically locate pin, two kinds of functions are integrated in one, improve the technical performance of equipment, very big raising building operations efficiency, and reusable, safe and reliable.
