Description
Technical field
The invention belongs to a kind of architectural furniture and job practices, especially relate to a kind of elevator shaft road junction bulk type iron railings and job practices.
Background technology
Existing commonly used elevator shaft road junction protective equipment often adopts fixedly iron railings or set up the steel pipe guardrail of welding; Instruments carryings such as the whole carrying of the former iron railings difficulty is fragile greatly, welding machine are time-consuming, the waste of embedded iron parts immobilization material is big, the fixing destructible shear wall concrete structure and the insecure potential safety hazard that exists of newly building of expansion bolt; The latter protects imprecision and is prone to and is destroyed, and has potential safety hazard.
Summary of the invention
The purpose of this invention is to provide a kind of elevator shaft road junction bulk type iron railings and job practices that is used for security protection, each member can be made convenient transportation in factory's batch machining; Adopt the sleeve spanner to install, safe and reliable, mounting or dismounting are simple; No consumption is used in turnover; Effectively reduce construction cost, the shear wall concrete finished product that helps newly building protection is applicable to the shear wall elevator shaft road junction of different in width and faces the hole, limit.
The objective of the invention is to realize like this; A kind of elevator shaft road junction bulk type iron railings, be characterized in this elevator shaft road junction bulk type iron railings security protection facility mainly by along elevator shaft road junction metope from bottom to top horizontal arrangement bottom girder, baffle plate, two crossbeams, capping beams, in the middle of crossbeam, pass and insert respectively up and down the column evenly arranged by a determining deviation along metope in back timber and the bottom girder circular hole the circular hole and on the baffle plate in the pipe, pass shear wall pre-embedded bolt hole be fixed on the set bolt at crossbeam two ends, vertically pass back timber and top cross beam about each one vertically add fixing bolt and form.Bottom girder is made by square steel, and circular hole is bored along a determining deviation in its end face middle part, so that column inserts.Baffle plate is welded by steel pipe and band steel, and this steel pipe is evenly arranged by a determining deviation, so that column inserts.Crossbeam is made by square steel, and its end face and bottom surface middle part symmetry and evenly bore circular hole by a determining deviation is so that column inserts; Have circular hole on the crossbeam top and bottom between this external the right and left circular hole, above circular hole less penetrate so that add fixing bolt; Following circular hole is bigger, is convenient to nut and sleeve spanner and stretches into and reinforce operation, symmetry and have slotted hole by certain spacing before and after the crossbeam facade; Front slotted hole width is bigger; Nut is satisfied in this hole and the sleeve spanner stretches into operation, and back slotted hole width is less, and this hole satisfies that set bolt penetrates and the fixed by nut crossbeam; Per two adjacent oval distance between borehole are 1/4 of slotted hole length, from the shear wall concrete, carry out the set bolt installation in the different spacing pre-embedded bolt hole to satisfy.Capping beam is made by square steel, and circular hole is bored along a determining deviation in its middle part, bottom surface, so that column inserts; Have circular hole on the crossbeam top and bottom between this external the right and left circular hole, below circular hole less penetrate so that add fixing bolt; Top circular hole is bigger, is convenient to nut and gets into reinforcing.Column is made by round steel.Add fixing bolt and make with full silk screw rod, tighten reinforcing with each nut up and down, the upper cap nut after the reinforcing is in the capping beam square steel, and following nut effectively prevents artificially to become flexible dismounting with common spanner in the crossbeam square steel.Set bolt is a gib headed bolt, reinforces with penetrating in the pre-embedded bolt hole and in the crossbeam slotted hole from shear wall, and it is fixing in crossbeam, to adopt the sleeve spanner to tighten with nut.
Elevator shaft of the present invention road junction bulk type iron railings job practices is: and shear wall formwork dismounting-crossbeam installation-bottom girder puts-and baffle plate puts-installation-reinforcing of column installation-capping beam.Shear wall formwork is removed: during dismounting shear wall formwork is added fixing bolt and extract out, reserve shear wall formwork and reinforce the pre-embedded bolt hole, and iron railings installation position metope and earth material are cleaned out; Crossbeam is installed: formwork reinforcement pre-embedded bolt hole penetrates from the shear wall back side set bolt; Adjusting position, the crossbeam left and right sides selects slotted hole to entangle anchor stud head to make the two ends extension elongation about equally; Fastening the hold-doun nut installation in the crossbeam slotted hole nut with the sleeve spanner, consistency from top to bottom all alignd its each circular hole of crossbeam up and down when two crossbeams were installed up and down on same vertical line; Bottom girder is put: bottom girder is put along the wall limit on the terrace of position placed in the middle, elevator shaft road junction, and the bottom girder end face is opened one of circular hole and is faced up; Baffle plate is put: baffle plate is erected be superimposed upon on the bottom girder, baffle plane is close to the left and right sides, elevator shaft road junction shear wall metope, the steel pipe on the baffle plate in the outside and the socket of each steel pipe all aim at the circular hole at bottom girder top; Column is installed: from two crossbeam top and bottom circular holes, insert the steel pipe socket that passes in the baffle plate to column downwards by root and inject in the bottom girder tip circle hole; Capping beam is installed: capping beam is lifted each circular hole alignment post top of its bottom is pressed down again, each column top is all anchored in the capping beam circular hole; Reinforce: according to distance between capping beam and crossbeam; The nut that full silk is added the fixing bolt top is screwed to earlier and adds appropriate location, fixing bolt stage casing; To add fixing bolt again inserts from the circular hole of capping beam top and makes this nut in capping beam; Add the fixing bolt lower end in putting in crossbeam end face circular hole, will add fixing bolt lower end snail cap with the sleeve spanner again and put in and tighten reinforcing in the crossbeam.
Elevator shaft road junction bulk type iron railings and job practices that the present invention proposes, each member can be made convenient transportation in factory's batch machining; Adopt the sleeve spanner to install, safe and reliable, mounting or dismounting are simple; No consumption is used in turnover; Effectively reduce construction cost, the shear wall concrete finished product that helps newly building protection is applicable to the shear wall elevator shaft road junction of different in width and faces the hole, limit.
