Description
Technical field
What the present invention relates to is a kind of double-deck comb shape template system and mounting method, is specifically effectively to solve while being provided with the construction of beard reinforced concrete prefabricated board that side spillage is serious, template peace is torn the extremely problem of inconvenience open.Belong to the realm of building construction.
Background technology
Steel-mixed combined beam structure is more and more applied in building and the bridge field of China, this wherein the form of structure of concrete prefabricated board+steel case beam because construction method is simple, be most widely used.Precast concrete plate thickness is generally all less than 60cm, some concrete prefabricated board cross sections adopt variable cross-section form, for guaranteeing precast plate quality of connection each other when mounted, concrete slab is equipped with beard reinforcing bar (beard reinforcing bar is formed by the main muscle extension of upper and lower two-layer reinforced mesh), and rebar spacing is comparatively intensive, the upper and lower two-layer beard reinforcing bar having is the loop configuration of sealing, and so the side template form of structure of concrete prefabricated board just seems particularly important.In prior art, be provided with beard reinforced concrete prefabricated board side form structure and mainly contain following three kinds of methods:
Method one; side template is divided into three parts: lower side template (being bottom layer of the reinforcing steel protective layer template), upper side template (being top layer reinforcement cover template), middle side template (being the template between upper and lower two-layer reinforced mesh), separately adopt flitch or steel pipe that side template is supported, fixed.The method formwork structure is simple and easy, processing is simple, but because template piecemeal is more, support fixing comparatively trouble, prefabricated concrete slab side is linear poor, the concrete prefabricated board that loop configuration or the cross section that is simultaneously sealing for beard reinforcing bar is variable cross-section form, wherein side template cannot normally be removed.
Method two, side template is by side template (being the above segment template of bottom layer of the reinforcing steel), leakage stopping block (for filling in the strip crevice of stifled comb shape template between upper and lower two-layer reinforcing bar) on lower side template (being bottom layer of the reinforcing steel protective layer template), comb shape.It can adapt to all types concrete prefabricated board side template construction compared with method one, but because adopting leakage stopping block by seam leak stopping, and so at the bottom of efficiency of construction, labour intensity is large, plugging effect is poor, and prefabricated concrete slab side is linear poor, and precision is lower.
Method three, side template adopts fast-easy closing-up net to make, this kind of template installation and easy, but employing fast easy-to-closing in net stencil, allow exfiltrating part mortar, on-the-spot civilized construction like this will be difficult to meet the industrialized requirement of Modern Construction Technology, and fast-easy closing-up net rigidity is poor, make prefabricated concrete slab side linear poor, precision is lower.
Summary of the invention
What the present invention proposed is a kind of double-deck comb shape template system and mounting method, and its object is intended to overcome the existing above-mentioned defect of prior art, effectively leak stopping, globality better, pacify tear open easy, and can the high bridge deck of prefabricated degree of precision.
The technical scheme that the present invention takes is: it is characterized in that comprising lower side template, outer comb shape template, internal layer comb shape template, fixed support, wherein descend side template to be positioned at the below of internal layer comb shape template, outer comb shape template, take bottom layer of the reinforcing steel as boundary; Outer comb shape template is supported on lower side template, and is fixed by fixed support and A screw rod, B screw rod; Internal layer comb-shaped mould board is positioned at top layer reinforcing bar; Described fixed support is arranged between beard reinforcing bar; Described outer comb shape template is comprised of panel, vertical strength plate and horizontal strength plate, wherein on panel, has the vertical notch corresponding with beard reinforcing bar, and the length of vertical strength plate is longer than panel, so that prop up the panel of lower side template while installing, thus realize spacing; Vertical strength plate and screw rod corresponding position arrange energetically plate; In described internal layer comb shape template, have the vertical notch corresponding with outer comb shape template; Described fixed support is comprised of cross bar, montant and brace, wherein on cross bar, montant, has circular hole, and correspondence arranges A nut, B nut, in the lower end of montant and brace, is provided with connection otic placode, and cross bar below is provided with limiting plate; The short diameter that is doubled in beard reinforcing bar of vertical notch length of the more outer comb shape template of vertical notch length of described internal layer comb shape template; Described internal layer comb shape template transverse notch length is greater than described outer comb shape template vertical slot mouth width, is less than the level interval of outer comb shape template vertical slot mouth.
Beneficial effect of the present invention is: double-deck comb shape template system, and its simple installation is basic forming after installation, without mode transfer; Good integrity, prefabricated concrete slab corner angle are clearly demarcated, precision is high; Internal layer comb shape template and outer comb shape template are complementary, efficiently solve while being provided with the construction of beard reinforced concrete prefabricated board that side spillage is serious, template peace is torn the extremely problem of inconvenience open, make quick construction, on-the-spot civilization, clean and tidy.
