Description
Technical field
The utility model relates to the reinforced concrete structure support system, is specially a kind of ring steel reinforced bar concrete structure inner membrance from steady support system.
Background technology
In the construction work, the high pier of bridge cast-in-place hollow, chimney stack, vertical shaft retaining wall etc. all need be used the reinforced concrete hollow structure, need stable internal mold when fluid concrete.
The internal mold of present most of similar engineering, significance level and cost depending on the inboard exposed face of circulus adopt respectively punching block or wooden model.But the stable of template mostly is vertically and horizontal struts system; Also utilize the intensity of concrete structure own, structurally the method by pre-buried suspension template.
When often constructing first floor, vertical force reaches ground by various forms, and second layer shuttering supporting is on the first floor template, after second layer concrete reaches some strength, after the dismounting first floor template, be mounted to the 3rd layer and continue construction, at this moment, all template weight are born by second layer built-in fitting.Successively construct to structural top with the method, begin to need every layer from the second layer built-in fitting is set.
The built-in fitting of circulus is actually in the hoop template and holes, insert bar dowel in the hole, bar dowel outside mounting nuts is fixed, when the concrete of cast has some strength, bar dowel also has certain stability, utilize the shear strength of bar dowel, except bearing this layer template weight, also the weight to upper former plays a supportive role before upper layer concrete does not reach some strength.
After concrete reaches intensity, because template has certain thickness in normal direction, there is certain taper in template in thickness approach, stripping is difficulty, built-in fitting stretches out the template certain-length in addition, template can only to the inside translation of level one segment distance (embedded bar length) after, could remove, often need use the instruments such as crowbar, very easily damage template; Exposed steel bar very easily makes moist and gets rusty, and need in time cut off the pre-buried bar dowel that all expose after the form removal, but directly affect concrete appearance with methods such as oxygen cutting remove.
For the ease of form removable, the boring of embedded bar all is slightly larger than bar diameter on the template, easily produces spillage during fluid concrete, reduces concrete quality and pollution structure outward appearance.
For preventing pouring concrete and the Lateral Force lower bolster displacement of vibrating, need carry out necessary support in the hollow-core construction inboard, directly affect the logistics transportation operation of vertical direction.
Summary of the invention
Easy spillage and affect the problem of vertical hauling operation when the utility model is removed difficulty, cast in order to solve existing ring steel reinforced bar concrete structure inner membrance provides a kind of ring steel reinforced bar concrete structure inner membrance from steady support system.
The utility model is to adopt following technical scheme to realize: ring steel reinforced bar concrete structure inner membrance is from steady support system, comprise some layers of annular inner membrance setting up and down, the annular inner membrance is by some membrane body in the arc to be formed by connecting, the place, slit of every internally adjacent side of membrane body be provided be positioned at its outside and with every internally membrane body catch that membrane body is fixing wherein, interior membrane body inboard all is fixed with horizontal gusset arranged in a crossed manner and vertical gusset, and interior membrane body inboard is provided with identical with its radian and is through two support bars on the vertical gusset, and an adjacent terminal bolt of two support bars is connected with positive and negative screw-thread sleeve.
Drive the support bar elongation by rotating positive and negative screw-thread sleeve, apply the outside tension force of hoop for interior membrane body, thereby be converted into annular inner membrance to concrete normal pressure, its normal pressure is offset by the concrete with some strength, improve the frictional force between annular inner membrance and the concrete, realize that hoop supports; The pouring concrete stage purpose of spillage not when simultaneously the catch that arranges of place, every internally membrane body slit realizes that annular inner membrance is flexible.
When the annular inner membrance is installed, only require that to satisfy the installation site accurate, wouldn't apply axial compression, connection between the interior membrane body adopts template to be connected and fixed card, fluid concrete and after concrete has some strength, apply axial compression by the support bar that rotates the internal membrane body of positive and negative screw-thread sleeve inboard, impel interior membrane body to be out of shape laterally, and then annular inner membrance tightly is pressed in concrete structural surface, under the effect of this pressure, improved the frictional force between annular inner membrance and the concrete structure, utilized this frictional force to bear the weight of annular inner membrance and other load, realized that support system is from steady purpose; Generally speaking, shellring shape inner membrance is installed from bottom to up and after internally the support bar of membrane body inboard applies axial compression, unclasp the axial stress of orlop annular inner membrance support bar, block-by-block unclamps interior membrane body, move on the membrane body block-by-block in should layer and be installed in shellring shape inner membrance top, cycling, when removing the superiors' annular inner membrance, after discharging the support bar circumference stress, suspend support in midair by built-in fitting temporarily, or adopt crane gear once the superiors' annular inner membrance to be extracted, overcome existing ring steel reinforced bar concrete structure inner membrance and removed difficulty, easy spillage and affect the problem of vertical hauling operation during cast.
The positive and negative screw-thread sleeve quantity of interior membrane body inboard is two, and above-below direction distributes, the two ends of each positive and negative screw-thread sleeve all are screwed with support bar, and the outer end of support bar all is fixed with diameter greater than the support termination of support bar diameter, when hollow pier (chimney) when inside is provided with closing slope, realize the change of the gradient by the length of regulating upper lower support bar, the support bar on each interior membrane body that is arranged so that of support termination can not stagger simultaneously, affects the support effect.
The utility model reasonable in design is reliable, a kind of internal mold that is the steel hoop concrete structure construction supports new system, in the tunnel ventilation To Construction of Silo, shaft sinking and two lining constructions is carried out synchronously especially, greatly shorten shaft wall open-assembly time, reduced construction risk; And do not take the vertical shaft central space, be convenient to vertical logistics corridor unimpeded, reduced cost when having shortened the duration, have advantages of be skillfully constructed, stressed clear and definite, be easy to implement, be applicable in the engineering of hollow pier, tunnel ventilation vertical shaft two linings.
