Detailed description of the invention
By describing technology contents of the present invention, structural feature in detail, realized object and effect, accompanying drawing is coordinated to be explained in detail below in conjunction with embodiment.
Refer to accompanying drawing 1-accompanying drawing 6, a kind of steel and wood composite stair template is the invention provides shown in accompanying drawing, comprise stair side form 1, to mark time positioning supporting frame, to mark time side form 2 and U-shaped buckle 3, the two ends up and down of described stair side form 1 are fixed with strengthens angle steel 4, strengthen the life-span fixedly improving stair side form 1 of angle steel 4, strengthening angle steel 4 is welded on stair side form 1 in the present embodiment, certainly, strengthening angle steel when also can adopt bolt in other embodiments is fixed on stair, stair side form 1 is provided with horizontal stripe bolt hole 11, described positioning supporting frame of marking time comprises fixed head 5, template baffle plate 6 and template support plate 7, template baffle plate 6 and template support plate 7 are fixed on fixed head 5, in the present embodiment, template baffle plate and formwork-support are welded on fixed head, template support plate 7 is 90 ° with the angle of template baffle plate 6, fixed head 5 is provided with fixing bar shaped bolt hole 51, fixing bar shaped bolt hole 51 is suitable with horizontal stripe bolt hole 11, and by set bolt, fixed head 5 and check of staircase are fixed together, the mark time bottom of side form 2 is located by template support plate 7, sidepiece is located by template baffle plate 6, U-shaped buckle 3 opening down, side form 2 of marking time is fixed with template baffle plate 6.
China's house, office building, school, hospital, hall, kindergarten, factory buildings etc. are built, structure stair step height is between 120mm-175mm, and stair tread thickness according to loading conditions between 80mm-150mm, in the present embodiment, the length of steel and wood composite stair template is set to 400mm, all kinds of building can be met, the stair construction requirement of structure, the length of side form needs to arrange according to concrete installation environment, in the present embodiment, described stair side form 1 comprises multiple side form unit, side form unit is directly by being connected with connecting bolt 81 by side form connector 8, side form connector 8 is provided with perforate, side form unit connecting portion is provided with screwed hole, connecting bolt 81 makes sides adjacent form unit fix through perforate and screwed hole.
By the setting of multiple side form unit and side form connector 8, stair side form 1 is made to adopt assembly type to install, concrete, the side form unit of length such as 1800mm, 1200mm, 1200mm, 900mm, 450mm can be set, and carry out assembly according to the different length of stair, above-mentioned length be inventor in process of production, the length that the utilization rate of statistics is the highest.
In the process of side form unit assembling, when running into platform turning, can produce barbed portion, in the present embodiment, described breach adopts wooden model 9 to carry out shutoff.
In the present embodiment, described horizontal stripe bolt hole 11 is arranged on stair side form 1 uniformly and equidistantly, and this technical scheme is different from the scheme that whole stair side form 1 arranges a rectangular horizontal stripe bolt hole 11, by the setting of multistage bolt hole, strengthens the intensity of stair side form 1.
In the present embodiment, stair side form 1 surface is provided with releasing agent layer, brushing evenly, after being convenient to build, the dismounting of template.
When stairway width is greater than 1.2 meters, side form 2 amount of deflection of marking time is excessive, therefore, in the present embodiment, described in mark time that side form 2 is other is provided with batten, to marking time, side form 2 is reinforced.
Enumerate in a specific embodiment the concrete installation steps of steel and wood composite template illustrated in the present invention below:
1, side form is installed:
According to staircase design width dimensions, gangboard bed die is installed stair side form 1, adjacent side form adopts side form connector 8 fixedly to be connected by connecting bolt 81, and further, tight for ensureing to separate seam, junction adds sponge strip 82.
2, to mark time the fixing of positioning supporting frame:
According to design size will mark time install bracing frame be placed on stair side form 1, fixed head 5 and stair side form 1 are fitted, horizontal stripe bolt hole 11 is overlapping with fixing bar shaped bolt hole 51, at this moment, set bolt is adopted firmly to be fixed on stair side form 1 at attaching nut by fixed head 5 through horizontal stripe bolt hole 11 and fixing bar shaped bolt hole 51 successively, by the design modifying fixed head 5 of two bolts hole and the relative position of falling bodies side form.
3, to mark time the installation of side form 2:
Be placed on formwork-support by the side form 2 of marking time through processing, a side and template baffle plate 6 fit, and are fixed with U-shaped buckle 3.
The opening of U-shaped buckle 3 is slightly less than the thickness that side form 2 of marking time is added up with template baffle plate 6, what U-shaped buckle 3 was engaged is more firm, in this enforcement, U-shaped buckle 3 is double-U-shaped buckle 3, guarantee to be connected firmly, because the lateral pressure produced in stair gangboard, concreting of marking time is less, above-mentioned reinforcement means meets construction demand.
Namely U-shaped buckle 3 completes the installation of whole guiding principle wood combined staircase template after engaging, the positioning supporting frame of marking time of suitable quantity is set as required, check and accept achievement afterwards, and with concreting, stair concreting is cloth in the middle part of stair as far as possible, prevents Concrete contamination bolt as far as possible, reaches after form removable condition until concrete intensity, by the form removable of guiding principle wood combined staircase, specifically comprise the following steps:
1, first the set bolt of stair side form 1 with positioning supporting frame of marking time is removed.
2, adjacent stair side form 1 junction plate is removed.
3, stair side form 1 is removed
4, open U-shaped buckle 3, locating support of marking time separates with side form 2 of marking time.
Whole stair template is removed simple, and form removable process can not cause damage to concreting.
Novel stencil design, solve that stair template installs, to reinforce difficulty large, the materials'use such as template, steel nail amount is large, can not a reusable difficult problem, improve the utilization rate of material, and simplify model sheetinstallat and reinforcement process, manual operation is simple, improve efficiency of construction, save artificial more than 60%.
Do not need the consumption of steel nail, flitch, the veneer used is torn open due to peace and is not simply damaged, and reusing number of times is common more than 5 times of now propping up wooden form.In addition, adopt steel and wood composite formula stair template can obvious accelerating construction progress.
The foregoing is only embodiments of the invention; not thereby the scope of the claims of the present invention is limited; every utilize manual of the present invention and accompanying drawing content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present invention.
