Description
Technical field
The present invention relates to the construction method of precast reinforced skeleton of sets of brackets on top of the columns of the construction method of a kind of building in the style of the ancients sets of brackets on top of the columns building operations accessory and building in the style of the ancients sets of brackets on top of the columns, particularly building in the style of the ancients band steel plate built-in fitting and preparation method thereof and building in the style of the ancients steel concrete sets of brackets on top of the columns.
Background technology
Flourish along with Tourism in China, building in the style of the ancients is built one after another in various places, and traditional wooden structures sets of brackets on top of the columns more and more can not meet the requirement of building practical and durability, so modern imitations building sets of brackets on top of the columns multi-form be greatly reinforced concrete structure; And sets of brackets on top of the columns girder construction of encorbelmenting is the form the most often adopted; Sets of brackets on top of the columns beam of encorbelmenting utilizes beam main tendon to anchor into the mode of main muscle tension+concrete anti-compression inside frame column, and the load in the deadweight of sets of brackets on top of the columns, the Large-area load of roofing and other directions is passed to frame construction; From anchor structure to beam-ends direction, utilize the method for the reduction sets of brackets on top of the columns beam section area, under ensureing the prerequisite of Cantilever Beams root effective cross-sectional area, reduce the deadweight of beam.
Traditional steel concrete sets of brackets on top of the columns construction is all that operation is with the form of main structure construction in work high above the ground: build enough large working platform; Lay bed die → assembling reinforcement → welding built-in fitting → installation side form → concreting, because sets of brackets on top of the columns girder construction of encorbelmenting needs the reduction sets of brackets on top of the columns beam section area; Thus, the manufacturing process operation of its sets of brackets on top of the columns beam steel cage is loaded down with trivial details, long construction period, and need to build on enough large operation platform in high-altitude to carry out, the scope of operation is limited to, and assembled operational danger is large, and the welding of built-in fitting and installation quality are difficult to ensure, sets of brackets on top of the columns scale error is comparatively large, and the spark simultaneously carrying out built-in fitting welding in high-altitude brings larger potential safety hazard to the construction of most of building in the style of the ancients for wooden structures.
Summary of the invention
The object of the present invention is to provide
oneplant the construction method of precast reinforced skeleton of sets of brackets on top of the columns of the building in the style of the ancients of isolating construction and preparation method thereof and building in the style of the ancients steel concrete sets of brackets on top of the columns; The method moves the making of the sets of brackets on top of the columns cage of reinforcement of building in the style of the ancients to ground from high-altitude, solves in the construction of traditional steel concrete sets of brackets on top of the columns, and the sets of brackets on top of the columns cage of reinforcement of building in the style of the ancients is with the weak point of main structure construction existing for the form of work high above the ground.
The technical scheme solved the problem is: a kind of precast reinforced skeleton of sets of brackets on top of the columns of building in the style of the ancients, comprise for fixing with support main steel bar stress, built-in fitting system for being connected with wooden construction after concreting is shaping, the main stress system of formation sets of brackets on top of the columns, for bearing and transmitting the sets of brackets on top of the columns skeleton reinforcing steel bar system of load; Coordinate cage of reinforcement, support whole sets of brackets on top of the columns shape and bear the sets of brackets on top of the columns stirrup of shearing force and torsional moment; Described built-in fitting system, sets of brackets on top of the columns skeleton reinforcing steel bar system and sets of brackets on top of the columns stirrup form one and pass through and reduce the whole reinforcement cage of section area for time;
