Description
Technical field
The invention belongs to underground cavern construction of concrete lining equipment technology field, be specifically related to a kind ofly can adapt to the concrete-lined steel form carrier variable camber gear of variable section cave depot that radian, span and height dimension change within the specific limits.
Background technology
Because underground cavern engineering section variation is many, have abnormally-structured section and side direction room etc., make it than general tunnel construction complexity, the steel form carrier that needs often to change different size in the time of cave depot concrete lining is to adapt to different arches, span, cave depot cross dimensions that wall is high; Simultaneously, because being subject to actual geographic environment, construction space, cave depot engineering affects, its condition of work is poor, mechanization degree is lower, labour intensity is larger, change chassis mould, the artificial formwork erection of repetitive cycling, form removal, mould carrying, formwork by multiple etc. can be to the engineering cost of the larger labour intensity of practice of construction increase and Geng Gao.Take a weight as 60T, length is as the common steel form carrier of 12m is as example, concrete lining early stage and artificial formwork erection of later stage and form removal approximately need 8 workman 10-12 days work periods altogether.
Cave depot section key dimension comprises that arch, span and wall are high.Arch refers to span and the ratio that loses height.The change of engineering hogging tip circle arc is to lose high, to encircle radius, home position change because the change of span causes on the one hand; Be the change of arch on the other hand, in engineering, common are 1/2 and 1/4 two kind of arch.At present common variable camber gear is that steel form carrier 201220247532.1 is mainly that vault circular arc is divided into three sections of circular arcs including the patent No., and by regulating three sections of circular arcs to carry out the actual vault circular arc of close approximation, error is larger.
Summary of the invention
The deficiency that the object of the invention is to overcome steel form carrier in existing cave depot construction, provides the cave depot concrete lining that a kind of efficiency of construction is higher, labour intensity is lower and error is less variable camber gear.
The technical scheme that realizes above-mentioned purpose is:
The concrete-lined variable camber gear of a kind of cave depot, comprises that triangle bearing, fixed triangle shape piece, adjustable triangular piece, gore connect bearing pin I, gore connects bearing pin II, cottor pin, gore connection leading screw, vault template assembly and side form assembly.Described triangle bearing is positioned at variable camber gear both sides, be bolted to side form assembly top and medial surface by horizontal installing plate and vertical installing plate with two groups respectively, the horizontal supporting plate of triangle bearing and bearing diagonal plate arrange two first group of through holes that axis is parallel to each other, it is parallel to each other that described fixed triangle shape piece and adjustable triangular piece all arrange three axis, with first group of second group of through hole that through hole is isometrical, described gore connect bearing pin I successively will first fixed triangle shape outside of left/right side through second group of through hole of right/left in first group of through hole on triangle bearing bearing diagonal plate and first fixed triangle shape outside of left/right side and triangle bearing hinged, order head and the tail are hinged successively in all the other fixed triangle shape pieces outside, hinged outside middle adjustable triangular piece outside and adjacent two fixed triangle shapes.Same method, fixed triangle shape piece inner side be positioned in the middle of adjustable triangular inner side by gore be connected leading screw, gore connection bearing pin II is hinged successively, and hinged with the horizontal supporting plate of both sides triangle bearing.Described cottor pin is arranged on gore and connects bearing pin I, gore connection bearing pin II end; Described vault template assembly is supported in variable camber gear outside by gore; Described side form assembly is positioned at the left/right side of variable camber gear.
This variable camber gear arranges an adjustable triangular piece in the middle of being positioned at and all the other, and several are positioned at the fixed triangle shape piece of adjustable triangular piece both sides.Within the scope of 4m-6m, be changed to example with 1/4 arch, span, described fixed triangle shape piece the first header board, the first rear plate are fixedly connected with by the first V shaped slab in the middle of being positioned at, and top arranges a first circular arc panel that fixing, radius is 2760mm with it; The first header board, the first rear plate upper outside and lower inside arrange respectively three groups of boss with holes, and through hole and second group of through hole are coaxially isometrical; Fixed triangle shape piece arranges 100mm and two series of 75mm width by the distance between the first header board, the first rear plate; Fixed triangle shape piece both upper ends thereof the second through hole cylinder axis spacing is 279mm.
Described adjustable triangular piece the second header board, the second rear plate are fixedly connected with by the second V shaped slab in the middle of being positioned at, and the distance between the second header board, the second rear distance between plates and fixed triangle shape piece the first header board, the first rear plate equates; Top arranges a second large circular arc panel such as fixing, radius and fixed triangle shape piece the first circular arc panel with it; Adjustable triangular piece both upper ends thereof is screw-nut structure, and nut is fixedly connected on the second V shaped slab two ends inwall, by regulating the screwing length of two ends leading screw and nut to realize the excursion of second group of through-bore axis spacing 271mm-381mm.
The middle steel pipe two ends that described gore connects leading screw arrange two positive and negative feed screw nuts, leading screw end arranges and first group of through hole, second group of the 3rd group of through hole that through hole is isometrical, and the 3rd group of through-bore axis spacing realizes the excursion of 250mm-310mm by adjusting screw nut screwing length.
Described gore connection bearing pin I, gore connection bearing pin II one end arrange the through hole of diameter 6mm, prevent that for installing bearing pin is from first group of through hole, second group of through hole, the 3rd group of cottor pin that through hole is deviate from.
Adopt the concrete-lined variable camber gear of a kind of cave depot that as above technical scheme provides compared with prior art, beneficial effect is:
(1) applied widely, can adapt to the adjusting of vault circular arc in different arches and span scope.In the time that the change due to span under same arch changes vault circular arc, the quantity, the position that only need increase and decrease, regulate corresponding gore to be connected leading screw with gore can be realized; In the time that 1/4 arch and 1/2 arch change, just can realize changing the quantity, the position that increase and decrease again, regulate corresponding gore to be connected leading screw with gore on corresponding triangle support base.
(2) change arc precision is high, can realize more accurately the lining cutting of cave depot concrete arch tip circle arc.Take 1/4 arch, span in 4m-6m range as example, under different spans, the worst error of actual circular arc and theoretical circular curve is only 2.285mm.
(3) labour intensity is low, change arc efficiency is high, and security performance is good.
