It is characterized by that on the upper plate a top window is cut, said top window can be used for making concrete construction operation in the lower cavity of said upper plate, in the top window position is set a movable window-contracting component capable of contracting window size, so that said form member can be used for in-situ casting reinforced concrete or prestressed reinforced concrete hollow floor, roof, wall body, foundation bedplate and open-web bridge, etc.
Description
(1) technical field
The present invention relates to a kind of shuttering member.
(2) background technology
The most of precast hollow slab that adopts of the building of brick mix structure and frame construction is as floor structure at present, this floor structure has advantages such as speed of application is fast, cost is low, but owing to firmly do not link between adjacent two precast hollow slabs, only use cement mortar blind, thereby not only globality is poor, be unfavorable for antidetonation, and phenomenons such as slit cracking, infiltration often occur, put to no little inconvenience and psychological pressure to resident family.In order to address the above problem, a lot of building have adopted the method for Cast-in-place concrete floor (hollow, solid).Though the Cast-in-place concrete floor has solved antidetonation and problems of crack, when construction, to use a large amount of templates, like this, not only increased expense, and the speed of application that slowed down, prolonged the duration.The patent No. is ZL00203695.9's " combination concrete hidden rib floor structure " utility model patent, it is made up of prefabricated plate, formwork, dark rib, upper plate, each prefabricated plate is horizontal positioned at interval, on prefabricated plate, be fixed with formwork, formwork comprises upper plate and side plate on every side, be provided with dark rib between contiguous prefabricated thin plate or the formwork, upper plate covers on the formwork, and connect as one with dark rib, this kind floor structure no longer needs to use in a large number template, accelerate speed of application, shortened the duration, thereby reduced cost.But, the lower shoe of this floor structure is a prefabricated plate, has the amalgamation seam each other, and globality is poor, if lower shoe adopts the cast-in-situ reinforced concrete plate, though good integrity, the problem that does not exist amalgamation to stitch, construction is inconvenient, the Cast-in-place concrete leakiness, be prone to problems such as voids and pits, therefore, develop a kind of novel shuttering member for being badly in need of.
(3) summary of the invention
The object of the present invention is to provide a kind of shuttering member, be applied to cast-in-situ concrete hollow floor after, can significantly improve the overall performance of superstructure, guarantee construction quality, and easy construction, construction cost are low.
Solution of the present invention is on the basis of existing technology, comprise upper plate, sidewall on every side, upper plate, sidewall surrounds uncovered basin-shaped component on every side, it is characterized in that having on the upper plate of described basin-shaped component one and carry out the skylight of concrete construction operation at the cavity of resorption of upper plate, there is the activity of the dwindling window size window member that contracts at the position, skylight.Like this, when the position, skylight has the activity of dwindling window size to contract window member, the end in skylight opens and seals all very flexible, help reducing the difficulty that shuttering member practices, thereby reached purpose of the present invention, the hollow building cover, roof system, body of wall, sole plate and the hollow bridges that are applicable to cast-in-situ reinforced concrete or prestressed reinforced concrete are used, and are particularly useful for hollow arch without beam and use.
Another solution of the present invention is on the basis of existing technology, comprise upper plate, sidewall on every side, upper plate, sidewall surrounds uncovered basin-shaped component on every side, it is characterized in that having a skylight of carrying out the concrete construction operation at the cavity of resorption of upper plate on the upper plate of described basin-shaped component, the position, skylight is provided with the blocking device of sealing skylight opening, has to connect on the skylight skylight connecting elements of Cast-in-place concrete under the Cast-in-place concrete and skylight.Like this, when the upper plate on the open shell is at least one removable cover, described shuttering member is applied in the process of In-situ cast concrete board, can pour into a mould the Cast-in-place concrete thin plate that Cast-in-place concrete forms the shuttering member bottom down to shuttering member by the skylight, thereby it is more convenient to construct, and guaranteed the pouring quality of Cast-in-place concrete thin plate, make it not be prone to voids and pits, after having watered, with the skylight sealing, build the Cast-in-place concrete between the shuttering member and top again, concrete can not enter in the cavity of shuttering member again, thereby guaranteed the pouring quality of In-situ cast concrete board, can not reduce the hollow rate of In-situ cast concrete board, help reducing construction cost, simultaneously, connecting elements has been reinforced the structure force transfer system of In-situ cast concrete board, make its weak part obtain reinforcement, thereby make that the In-situ cast concrete board structural performance is more even, thereby reached purpose of the present invention, be applicable to the hollow building cover of cast-in-situ reinforced concrete or prestressed reinforced concrete, roof system, body of wall, sole plate and hollow bridges are used, and are particularly useful for hollow arch without beam and use.
Another solution of the present invention is on the basis of existing technology, comprise upper plate, sidewall on every side, upper plate, sidewall surrounds uncovered basin-shaped component on every side, it is characterized in that having a skylight of carrying out the concrete construction operation at the cavity of resorption of upper plate on the upper plate of described basin-shaped component, at least one lightweight core is arranged in the skylight opening, and the lightweight core stretches into below the limit, skylight.Like this, when having a cavity of resorption on the upper plate of basin-shaped component when carrying out the skylight of concrete construction operation at upper plate, described shuttering member is applied in the process of In-situ cast concrete board, can pour into a mould the Cast-in-place concrete thin plate that Cast-in-place concrete forms the shuttering member bottom down to shuttering member by the skylight, thereby it is more convenient to construct, and guaranteed the pouring quality of Cast-in-place concrete thin plate, make it not be prone to voids and pits, after having watered, with the skylight sealing, build the Cast-in-place concrete between the shuttering member and top again, concrete can not enter in the cavity of shuttering member again, thereby guaranteed the pouring quality of In-situ cast concrete board, can not reduce the hollow rate of In-situ cast concrete board, help reducing construction cost, simultaneously, the lightweight core is with the skylight opening complete closed, make it in the process of practicing, Cast-in-place concrete can not pour in the shuttering member from skylight opening, thereby has reached purpose of the present invention, be applicable to the hollow building cover of cast-in-situ reinforced concrete or prestressed reinforced concrete, roof system, body of wall, sole plate and hollow bridges are used, and are particularly useful for hollow arch without beam and use.
Feature of the present invention is that also the described window member that contracts has scuttle.Like this, when the window member that contracts has scuttle, can very easily preheating embedding line be mounted in the shuttering member, and not need to punch, reduce the loss of shuttering member, save cost by scuttle.
Feature of the present invention is that also the described window member that contracts has the tubulose hole.Like this, when the window member that contracts has the tubulose hole, can very easily preheating embedding line be mounted in the shuttering member, and not need to punch, reduce the loss of shuttering member, save cost by scuttle.
