Abstract
Provided is a manufacturing method for a formwork shear wall assembled in a modularized mode. Steel reinforcement cage wall units are arranged, and each steel reinforcement cage wall unit is fixedly connected with nets on the two sides through connecting mechanisms between the sides of a steel reinforcement cage wall and the nets so that a framework shear wall unit assembled in a modularized mode can be formed. Each connecting mechanism is a steel plate with connecting members or is a connecting block formed by welding a U-shaped connecting part to a V-shaped connecting part in a crossed mode. The formed framework shear wall units are connected through the connecting mechanisms and the nets, assembled through vertical ribs or horizontal ribs in a connected mode and then filled with concrete in a pouring mode, and therefore the formwork shear wall assembled in the modularized mode is formed. Steel reinforcement column cages and the nets can be integrally manufactured in factories, and the modularized formwork shear wall is formed; according to dimension requirements of different shear walls, the multiple modularized formwork shear walls are arranged and spliced according to a required dimension so as to form a shear wall framework, and the concrete is poured into the framework. According to the method, operation is simple, construction efficiency is improved, and the construction progress is accelerated.
Description
Technical field
The invention belongs to building engineering field, it is related to a kind of lay wire shear wall for building, particularly one kind can be by arbitrarily large
The lay wire shear wall of little module combination.
Background technology
The method of traditional construction reinforced concrete wall, is the template using face-to-face setting, the volume being defined in template
Interior cast concrete, is to be connected by connecting rod between template, connecting rod by template wall outside locking piece cross locking, concrete is poured into a mould
Afterwards, reclaim template, take out locking piece.The reinforced concrete wall that this method manufactures, plank sheathing is just washed in a pan after using several times
Eliminate, the expense using steel form is too high, and also need to correct using rear；It is half envelope that traditional method adopts " container " of template composition
Close form, bubble or air are difficult to discharge, and construction quality is difficult to be guaranteed.
With the development in epoch, building trade is also evolving, and adopts metal building in building reinforced concrete wall
Lay wire replaces conventional template to be widely used, and this architectural lay wire have passed through 4 differentiation：
Develop for the first time, patentee's Aihua YANG is in the patent No.：" 03264539.2 ", patent name：" mould is built in free removal
Net ", and the patent No.：" 200310116873.0 ", patent name：A kind of mould is disclosed in the patent of " building model net wall structural element "
Net, this lay wire, when being assembled into wall body construction, easily produces warpage and out-of-flatness it is impossible to ensure the overall construction matter of body of wall
Measure, and making assembling relies primarily on and is accomplished manually.
Develop for second：Patentee's Wang Lijiu is in the patent No.：" 02109180.3 ", patent name：" combination lacing wire building
Employ ribbed stiffener in lay wire " and fixing W-shape connects reinforcing bar, the problems such as substantially solve warpage.Be particularly well-suited to "+",
" L ", T-shape build the connectivity problem of node, but are still fixed using tapping screw so as to make in ribbed stiffener and lay wire junction
The a large amount of manpowers of standby needs；It is wayward that dowel is prepared into W-shape；Different lay wire module level directions connect more complicated.
Third time develops:Patentee's Luo dongwei is in the patent No.：" 201010153360.7 ", patent name：" expansion dragon
Skeleton component ", the patent No.：" 200520013628.1 ", patent name：" Integral expansion keel ", and the patent No.：
" 201020506823.9 ", patent name：One-time formed expanding dragon is adopted in " laterally carrying the expanding keel of connector "
Bone and the bayonet unit of fixing lay wire, it is to avoid the waste of steel, but processing get up more numerous and diverse it is impossible to batch production.
4th differentiation：Patentee's Luo dongwei is in the patent No.：" 201120546052.0 ", patent name：A kind of " c-type
Employ reinforced C-type steel material in Os Draconis " as the skeleton of architectural lay wire, the method technology is more ripe, but with lay wire
Connect the connected mode still needing nailing etc, and material therefor is expensive.
Therefore, although the metal lay wire in building concrete wall have passed through four differentiation, there are significant improvement, building gold
Belong to lay wire and still there is manufacture method complexity, the problem of processing difficulties in work progress, and, material therefor price is higher,
Efficiency of construction is relatively low, does not reach preferable construction effect in work progress.
