PC wallboard moulds with window opening module
Technical field
The invention belongs to building product technical field, and in particular to a kind of PC wallboard moulds with window opening module.
Background technology
In recent years, as economic development, building trade are increasingly paid attention to energy resource consumption, environmental pollution.In building field The architecture construction of traditional reinforced concrete structure, often using based on situ wet operation, this mode of construction will not only consume largely Timber does end template and backing material, and energy consumption is big, low construction efficiency, the engineering time is long, produces noise and dust, while right Surrounding environment has larger pollution.Therefore, in recent years, building field starts to introduce the concept of modularized house.Modularized house is not Be same as traditional building construction, many structures of usual modularized house as used in being built house precast beam, precast wall body, Precast stair etc., it can shift to an earlier date and be machined in plant produced line.In use, directly above-mentioned prefabricated components are transported to job site It is cast-in-place that assembly is carried out afterwards, finally connects into building.Modularized house possesses environmental protection, the pollution for reducing site operation, construction effect The characteristics of rate is high, can be one of preferred embodiment of house construction of modernization in the construction compared with completion house in casual labourer's phase.
In foregoing every prefabricated components, precast wall body is essential critical component.Tradition is carrying out dry wall When system is made, all using the first wiretie skeleton directly in internal lobe wall mould, then the mode that later stage cement pours.Aforesaid operations Mode has problems in that:First, due to when each precast wall body manufactures, being required for making steel in internal lobe wall mould Tendons skeleton so that the producing efficiency of precast wall body is relatively low.Second, the current more structure using sandwich heat preservation wallboard of PC walls, The both sides of siphonal lobe wallboard in the interlayer structure and top dimension all exceed internal lobe wallboard 5-30cm, and should be needed beyond part exposed Insulation material.All it is each internal lobe wall side for first taking composition internal lobe wall mould apart when tradition carries out the form removal operation of internal lobe wall mould Mould, then each internal lobe wall side mould is directly subjected to horizontal direction dragging along basal plane.Above-mentioned forceps horizontal pulling action, can cause internal lobe wall side Mould directly scrapes above-mentioned insulation material, or even can scrape damage the above-mentioned of siphonal lobe wallboard and exceed part, causes the quality of precast wall body to lack Fall into.Third, prefabricated panel is not only in itself a monoblock plate body, often it is required for being reserved for the external part placement such as pipeline thereon Groove or circular hole.When carrying out precast wall body making habitually in the past, all directly the built-in fittings such as pipe are banded on framework of steel reinforcement, or will be pre- Embedded part is positioned over after basal plane axially to be penetrated bolt and is fastened at the screwed hole reserved on basal plane again, corresponding to be obtained after form removal Pipe hole or the corresponding tank circuit.However, under active force caused by pouring, vibrate and harden in cement, built-in fitting often occurs Displacement situation, cause the groove after final molding or circular hole displacement problem occur.Finally, the precast wall body with window opening is public The complex component of the production method recognized.Window opening module traditional at present is all directly correspond to window shape to be formed one Body mould, such as when window opening is cuboid, window opening module is integrally " mouth " word frame like structure, by that analogy.Above-mentioned construction Window opening module have problems in that:After window opening module is put into the die cavity of internal lobe wall mould, the laying of framework of steel reinforcement and water Mud pours to be carried out in the space between window opening module and internal lobe wall mould.After the completion of hardening of cement and need to carry out window opening During the dismounting of module, must just vertical lifting machine be relied on to extract window opening module along vertical.Because window opening outward appearance is usual Possess substantial amounts of turning (also known as inner corner trim), cause during vertical lifting because window opening module and cement pull with stress concentration effect and Cause window opening turning damaged, the final outward appearance for causing precast wall body produces defect.Once the above-mentioned open defect of generation, can only just lead to Later phase reparing process is repaired, and virtually also increases the cost of manufacture of precast wall body.In addition, window opening is simultaneously at present Not exclusively simple smooth hole body, by taking rectangle window opening as an example, needed thereon along the drip for needing setting groove-like, lower edge Rectangular-shaped with inclined plane of arrangement returns water slope.Obvious, such as use integral hoisting technique, the vertical lifting side of window opening module To just with return water slope and drip position produce interference, this be also why at present most of assembled architecture components without Method realizes the main reason for said structure.

The beneficial effects of the present invention are:
1), the present invention solves traditional direct carries out framework of steel reinforcement and ties up etc. to grasp caused by operation in mould cavity Make the defects of efficiency is low, the internal lobe wall side mould of U-shaped locating slot is carried by the use to look for another way, first by U-shaped locating slot To avoid out the path that falls into of the end reinforcing bar of framework of steel reinforcement, then the affixed property of Qian He between spacer and U-shaped locating slot come it is true Protect and affixed effect is positioned to the end one by one of above-mentioned end reinforcing bar, and then realize that the preprocessing of whole framework of steel reinforcement and later stage are whole Body acts the function of hanging in mould.Because framework of steel reinforcement is without the scene processing in mold cavity again, therefore can be more with pre-production Framework of steel reinforcement, it is necessary to when carry out the later stage again and integrally enter modulo operation, the producing efficiency of precast wall body obviously can obtain greatly Lifting.
In addition, it is contemplated that many precast wall bodies are all necessarily equipped with window opening at present, and therefore, the present invention also enters to window opening module Corresponding structure of having gone is improved.In above-mentioned, present invention employs knockdown window opening modular construction, by by window opening module with lead Vertical plane is blocked, so as to obtain each submodule structure.When needed, the split of each submodule is passed through, you can easily combination is formed Required window opening module.What is more important, the upper edge for the window opening being parallel to each other for returning water slope and drip is arranged for needs With lower edge, only blocked once by vertical truncation surface, in other words, during each form removal, return the die cavity of water slope and drip always most Horizontal dismountable is carried out again afterwards, to ensure to return the Forming Quality of water slope and drip.And for without drip and returning the window opening on water slope Left side wall and right side wall, then blocked by straight flange truncation surface even more more twice.When needed, by first along vertical to and Dismantle straight flange submodule, so as to reserve the activity space of angle Terminals Die horizontally;One of angle Terminals Die is carried out afterwards again along lead The horizontal of truncation surface of hanging down pulls away inner corner trim to sliding movement, and then by angle Terminals Die horizontal direction.Due to aforesaid operations, can effectively keep away Exempt from the concrete disrepair phenomenon of internal corner part at window opening, reduce and even remove later stage rehabilitation cost from.Meanwhile and due to above-mentioned angle end Submodule pull away action be it is parallel return water slope and the projection direction of drip, therefore can also realize and water slope is returned at window opening and is dripped The one-shot forming effect of groove.
For the mould of internal lobe wall side, it has been designed to special cantilever design by the present invention.With it is common constitutionally stable Cubic cylindricality side mould is different, the internal lobe wall side mould of the triangle of cantilevered construction, and it inherently exists when individually placed unstable Property.During actual use, four internal lobe wall side moulds are abut against each other so as to form quadro frame shape with cantilever-shaped triangular prism shape construction Internal lobe wall mould, now due to the affixed property and the supportive of levelling bolt between each internal lobe wall side mould, be able to ensure whole The stability and reliability of mould work.When needing form removal, affixed cooperation and the phase of four internal lobe wall side intermodes are first removed Fastening member is answered, turns levelling bolt afterwards.The suspension end of the level board of internal lobe wall side mould is gently beaten from top to bottom, and this is interior Ye Qiang sides mould can produce upset because of the unstability of self structure and along direction is beaten, and overturning pivot is the bottom of vertical plate. When producing above-mentioned rotary movement, the top of the vertical plate of internal lobe wall side mould can gradually reduce, and now carry out withdrawing pattern operation again, interior The top of the vertical plate of Ye Qiang sides mould would not scratch directly over siphonal lobe wall part, also just be not present so-called siphonal lobe wall at protect The Structural Faults situation at the positions such as warm layer, the Forming Quality of siphonal lobe wall can be effectively ensured.
The occasion of preserved pipeline hole arrangement is carried out in precast wall body for some needs, the present invention is individually designed reserved Pipe-line system.The system is included in reserve on basal plane and portalled, and positioning plectane is fixed at the hole, so as to realize positioning plectane Positioning it is affixed.Afterwards, pipe sleeve is inserted in positioning plectane, and pressing plate is shelved above pipe sleeve.Pressure is fastened by trip bolt Plate and positioning plectane, so as to realize from top to bottom substrate hold-down function of the pressing plate to pipe sleeve.Now, the axial displacement of pipe sleeve is by pressing plate And basal plane is limited, the radial action of pipe sleeve is then positioned plectane or even the pressing plate of ladder shaft-like is constrained, therefore anyway By external force, pipe sleeve acts all without extra deflection is produced, and this make it that the preserved pipeline hole site of final molding is extremely accurate, Customer requirement can effectively be met.
2), on the cross section of internal lobe wall side mould, the horizontal of level board is more than the vertical of vertical plate to highly to length.Change Yan Zhi, when level board, vertical plate and the triangle gusset for forming internal lobe wall side mould are collectively forming triangular shape cross section, internal lobe wall side The center of gravity of mould should be more biased towards the cantilever end of level board.So, in form removal, only need less power that internal lobe wall side mould can be achieved Rapid turnover, operating efficiency obviously can obtain further lifting.
3), in fact, when carrying out the fixed operation of spacer, should follow:Prefabricated matching internal lobe wall mold cavity Framework of steel reinforcement;Framework of steel reinforcement is moved into the die cavity of internal lobe wall mould;By the positioning arc groove of each spacer being caught in correspondingly one by one Framework of steel reinforcement end reinforcing bar on;After spacer is caught in, by spacer along end reinforcing bar bearing of trend and to U-shaped fixed Position groove direction is slided, until spacer enters U-shaped locating slot vallecular cavity., can be by many when spacer enters in U-shaped locating slot Mode carries out both fastenings:Both such as directly fastened by reserved bolt, or even entered by the mode such as being bonded or welding Both are affixed etc. for row, need to only ensure that spacer can not relatively U-shaped locating slot generation when carrying out cement and pouring, vibrate and harden Sliding movement, so that it is guaranteed that pouring the high-quality of rear pre-formed cavity.Present invention preferably employs matching somebody with somebody for fin and locating rod Structure is closed, seam fiting effect from inside to outside is on the one hand realized with fin;On the other hand then with locating rod and locating ring Coordinate and to tense spacer in outside, so as to together realize that the two-way clamping to spacer fastens purpose with fin.And why It is to be unlikely to be single use because of spacer using locating rod and outside built-in structure of the locating ring as spacer, and it is past Arranged more than ten or even tens toward on an internal lobe wall side mould;As a result of positioning ring design, a locating rod is with regard to energy Also cross several even all of locating rings, using upper obviously extremely efficient and convenient, location efficiency is high.
4), the further preferred scheme as such scheme, window opening module of the invention are actually with drip and returned Along being broadside using left side wall and right side wall as the rectangular frame structure of long side where water slope, the structure is also the tradition of window opening Shape.Constructed by the way that straight flange submodule is designed as into isosceles trapezoid, in form removal, directly by straight flange submodule vertical, extraction is upwards Can.The architectural feature of the isosceles trapezoidal structure of straight flange submodule and the trapezoidal base of straight flange submodule upward, can effectively be lifted The efficiency and convenience of whole form removal operation.It is preferred that it is 80 ° that the broadside of vertical truncation surface and window opening module, which forms angle, should Angle can be more convenient the stripping operation of straight flange submodule relative angle Terminals Die, and it is apparently more convenient to operate.
5), because the lateral wall of window opening module is die cavity face, in other words, the rigidity of increase window opening module itself is such as wanted, Ensure that window opening module can resist the power that cement is poured and bestowed when hardening, now for reinforcement window opening module stiffness by itself The components such as supporting plate should be arranged at the madial wall of window opening module.It is preferred that each submodule for forming window opening module is both designed as Box like structure, now cassette bottom is to form the part in above-mentioned die cavity face, and box wall is then formed for being fitted to each other or coordinating basal plane Mating surface, to ensure the reliability of overall work.
6), extremely heavy in view of window opening module weight, even if being split as some submodules, each submodule also still possesses certain matter Amount, along with form removal, window opening module again can by the power for the corresponding submodule extraction of obstruction bestowed after hardening of cement, therefore, It is of the invention especially to arrange auxiliary withdrawing pattern component.During actual use, dismantle what straight flange submodule was engaged with angle terminal intermode first Bolt, withdrawing pattern screw is turned afterwards, using top lift of the withdrawing pattern screw with respect to basal plane, so as to which straight flange submodule vertical be lifted off to ground Basal plane, it is finally reached the auxiliary withdrawing pattern effect for straight flange submodule.
7), levelling bolt, the function of support internal lobe wall side mould is on the one hand played, on the other hand, also functioned to certain internal The levelling function of Ye Qiang sides mould, to ensure the vertical in internal lobe wall die cavity face.And housing screw, then it is used to ensure internal lobe wall side mould With respect to the abutting of basal plane, not dry cement is avoided to produce seepage shape along the gap of internal lobe wall side mould and basal plane under pressure Condition, to lift the reliability of precast wall body casting process, and effectively ensure the Forming Quality of precast wall body, reduce the later stage repair into This.
