As preferably, described intervalve is rhs-structure, and described angle mould body dual-side port is provided with tube connector and is connected with intervalve.
As preferably, described absolute altitude controlling organization comprises the thread pore structure at diagonal brace middle part and is combined on the screw rod in screwed hole.
As preferably, described thread pore structure comprises the unthreaded hole at diagonal brace middle part and is welded in the nut on unthreaded hole top.
As preferably, described screw rod upper end is provided with nut, and described screw rod lower end is provided with a round steel.
As preferably, in described four intervalves, wherein a tongue and groove is respectively opened at two of any one, and described tongue and groove length is consistent with angle mould tube connector length.
The present invention also provides above-mentioned washroom to fall plate sizing formwork construction method, it is characterized in that: described formwork adopts the formwork described in claim 1 to 7 any one, and concrete construction method is:
Step 1: four angle moulds and four intervalves are enclosed to a rectangle frame;
Step 2: rectangle frame is moved into washroom in place, regulate the absolute altitude of formwork to ensure washroom thickness of slab by absolute altitude controlling organization simultaneously;
Step 3, by rectangle frame and periphery beam main tendon fix tightly and build floor concrete;
Step 4: remove formwork.
Further, washroom falls plate sizing formwork concrete construction method and comprises the steps:
Step 1: the tube connector that four angle moulds are inserted respectively at intervalve two ends makes four angle moulds and four intervalves enclose a rectangle frame;
Step 2: control the absolute altitude of formwork support member by screw in screw rod on nut, wherein round steel bottom butt floor template, the height of four angle moulds is all adjusted to corresponding absolute altitude;
Step 3, controls well after formwork axial location with galvanized wire rectangle frame and the fixation of periphery beam main tendon, then builds floor concrete;
Step 4: in the time that face is received in floor concrete initial set, the screw rod of controlling height is screwed out, mend real floating screw position concrete, the intervalve that two is provided with tongue and groove is painted in advance and is marked with mark, first prizes marked intervalve, then remove its excess-three root intervalve and four angle moulds when form removal.
The present invention's formwork support member of shaping is mainly made up of angle mould A and four square tube interlude B of four identical moulding.Angle mould A two right-angle side size unifications are decided to be 500mm, empty size-2 × 500mm in interlude B length=washroom reality.Four angle mould A and four straight square tube B enclose a rectangular elements, after waiting floor steel bar colligation to complete, this member location are fixed on to relevant position as falling plate side form.Make simple, easy construction, reuse, promote concrete floor and fall the Forming Quality at plate place.
Detailed description of the invention
Illustrate washroom of the present invention and fall the embodiment of plate sizing formwork referring to Fig. 1 to Fig. 5, comprise four angle moulds 1 and four intervalves 2, described four angle moulds and four intervalves enclose a rectangular elements, wherein, four angle moulds are arranged at respectively four jiaos of rectangle, four intervalves are arranged at respectively four limits of rectangle, are respectively equipped with the absolute altitude controlling organization of a control formwork absolute altitude on described four angle moulds.Described angle mould comprises a L shaped angle mould body 11, between described angle mould body dual-side, is provided with a diagonal brace 12, and described angle mould body and diagonal brace are rhs-structure.Described intervalve is rhs-structure, and described angle mould body dual-side port is provided with tube connector 13 and is connected with intervalve.Described absolute altitude controlling organization comprises the thread pore structure 14 at diagonal brace middle part and is combined on the screw rod 3 in screwed hole.Described thread pore structure comprises the unthreaded hole at diagonal brace middle part and is welded in the nut on unthreaded hole top.Described screw rod upper end is provided with nut 31, and described screw rod lower end is provided with a round steel 32.In described four intervalves, wherein a tongue and groove 21 is respectively opened at two of any one, and described tongue and groove length is consistent with angle mould tube connector length.
Plate sizing formwork construction method falls in above-mentioned washroom,
Step 1: four angle moulds and four intervalves are enclosed to a rectangle frame;
Step 2: rectangle frame is moved into washroom in place, regulate the absolute altitude of formwork to ensure washroom thickness of slab by absolute altitude controlling organization simultaneously;
Step 3, by rectangle frame and periphery beam main tendon fix tightly and build floor concrete;
Step 4: remove formwork.
Concrete,
Step 1: the tube connector 13 that four angle moulds 1 are inserted respectively at intervalve 2 two ends makes four angle moulds and four intervalves enclose a rectangle frame;
Step 2: control the absolute altitude of formwork support member by screw in screw rod 3 on nut, wherein the height of 4, four angle moulds of round steel 32 bottom butt floor templates is all adjusted to corresponding absolute altitude;
Step 3, controls well after formwork axial location with galvanized wire rectangle frame and the fixation of periphery beam main tendon, then builds floor concrete 5;
Step 4: in the time that face is received in floor concrete initial set, the screw rod of controlling height is screwed out, mend real floating screw position concrete, the intervalve that two is provided with tongue and groove 21 is painted in advance and is marked with mark, first prizes marked intervalve, then remove its excess-three root intervalve and four angle moulds when form removal.
