Description
Technical field
The utility model relates to building operations field of reinforcement, specifically a kind of cast-in-situ stair formwork reinforcement structure.
Background technology
The traditional method of cast-in-situ stair formwork reinforcement is generally adopt the instruments such as wood support, iron wire to reinforce kickplate, and on-the-spot formwork is inconvenient, makes verticality planeness all be difficult to reach requirement.Meanwhile, traditional stair formwork erecting mode is due to level and the single structure stress of vertical supporting point is poor, poor stability, globality are poor, and in construction, distortion is large.And be closed flat in process marking time, to mark time surface contact for the support bar of reinforcing template and iron wire and concrete, be closed flat trowel and cannot stretch into and be closed flat inconvenience.
By above-mentioned, the traditional approach analytic induction that stair template is reinforced is summed up: reinforcing mode is improper, formwork poor stability, formwork way be closed flat operating space not, be affect the shaping principal element of stair outward appearance.
Summary of the invention
For solving the problems of the technologies described above, the utility model provides a kind of cast-in-situ stair formwork reinforcement structure, improve the drawback of traditional cast-in-situ stair template-setup, utilize novel cast-in-situ stair shuttering fastening member, its structure is very simple, there is constructing operation convenient, saving of work and time, shaping perception is good, and cost is low, repeatedly can have enough to meet the need use, save the advantages such as engineering cost.
The technical scheme that the utility model adopts is:
A kind of cast-in-situ stair formwork reinforcement structure, comprise the longitudinal fixed bar be in tilted layout along building body step surface, described longitudinal fixed bar is at least two, the longitudinal fixed bar of each root is fixed with multiple girth member by cruciform fastening for falsework from top to bottom, equidistantly, girth member props up riser template, and the riser template on same step surface is at least pushed against by two girth members.
Described longitudinal fixed bar is two, two mutual horizontal arrangement of longitudinal fixed bar, is separately positioned on two longitudinal fixed bars, two girth members be positioned on same step surface, jointly props up riser template, be fixed riser template.
Described girth member is bending type short steel pipes.This bending type short steel pipes described two sections of waste and old steel-pipe weldings form, and its angle α is 150 °, its outer brush skin of paint.The epimere steel pipe of described bending type short steel pipes is fixedly mounted by cruciform fastening for falsework and longitudinal fixed bar, and the hypomere steel pipe of bending type short steel pipes perpendicular to facade of marking time, and props up riser template.
Described longitudinal fixed bar both ends connect horizontal fixed bar respectively, and horizontal fixed bar is anchored in vertical rod.
A kind of cast-in-situ stair formwork reinforcement of the utility model structure, technique effect is as follows:
1), girth member is bending type short steel pipes, and this bending type short steel pipes two sections of waste and old steel-pipe weldings form, and turn waste into wealth, and makes simple.Bending type short steel pipes outer brush skin of paint, plays and prevents action of rust, simultaneously also eye-catching by paint marks, prompting constructor.
2), longitudinal fixed bar both ends connect horizontal fixed bar respectively, and horizontal fixed bar is anchored at vertical rod, guarantee that it forms the strong entirety of rigid, strengthen its steadiness.
3), the utility model under the prerequisite not increasing difficulty of construction and cost, solve reinforcing mode improper, formwork poor stability, formwork way and be closed flat the inadequate disadvantage in operating space.
4), the utility model mainly utilizes " the bending type short steel pipes " of processing and fabricating to reinforce playing facade template, strengthens the steadiness of template, improves formwork way, makes tread be closed flat operation to be improved.Ensure after form removal that stair step perception is effective, turnover rate is high, can be used for dissimilar stair tread formwork strengthening construction.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is bending type short steel pipes structural representation of the present utility model.
Wherein: the longitudinal fixed bar of 1-, 2-fastener, 3-girth member, 4-riser template, the horizontal fixed bar of 5-, 6-vertical rod, 7-gangboard, 8-side template.
Detailed description of the invention
As Fig. 1, as indicated with 2, a kind of cast-in-situ stair formwork reinforcement structure, comprises the longitudinal fixed bar 1 be in tilted layout along building body step surface, and described longitudinal fixed bar 1 is at least two, the present embodiment preferably two, and two longitudinal fixed bars 1 are arranged in both sides, stair face.Fastener 2 is the long common cruciform fastening for falsework in building site preferably.
The longitudinal fixed bar 1 of each root is fixed with multiple girth member 3 by cruciform fastening for falsework 2 from top to bottom, equidistantly, and girth member 3 props up riser template 4.Owing to being two longitudinal fixed bars 1, the riser template on same step surface 4 is pushed against by two girth members 3.Two mutual horizontal arrangement of longitudinal fixed bar, are positioned on building body step surface in skewed.Like this, be separately positioned on two longitudinal fixed bars, two girth members 3 be positioned on same step surface, jointly prop up a riser template 4 and riser template 4 is fixed, and in length and breadth to straight, fastening.
Described girth member 3 is bending type short steel pipes.This bending type short steel pipes described two sections of waste and old steel-pipe weldings form, and its angle α is 150 °, its outer brush skin of paint.
Making step:
(1) selection: the thick waste and old steel pipe of Ф 48*3.5mm, often saves length at more than 150mm;
(2) make processing: shown in Fig. 2, weld with two joint 150mm length steel pipes, in welding process, two joint short steel pipes are cut into groove, and after making welding fabrication, steel pipe interior angle becomes 150 ° of angles, weld seam requirement is full and polish smooth, brushing paint.
The epimere steel pipe 3.1 of bending type short steel pipes is fixedly mounted by cruciform fastening for falsework and longitudinal fixed bar 1, and the hypomere steel pipe 3.2 of bending type short steel pipes perpendicular to step surface, and props up riser template 4.
Two longitudinal fixed bar 1 both ends add two horizontal fixed bars, 5, two horizontal fixed bars 5 respectively and are anchored in four vertical rods 6 of formwork bracing system.
Points for attention:
During formwork erection, receiving riser template 4 upper and lower end of surface layer should maintain an equal level, and in the process of receipts face, is closed flat trowel and will stretches in template lower port, guarantee form removal rear tread pattern smooth straight, effect is attractive in appearance.
Comprehensive benefit analysis:
1, reduce artificial secondary repair stair step surface, every # stair be 3 work day × 250 yuan/work day=750 yuan;
2, increase construction efficiency, every # stair be 3 work day × 250 yuan/work day=750 yuan;
3, less template loss, every # stair are about 200 yuan;
4, increase girth member 3 to make processing charges and be: every # stair about 0.5 work day × 250 yuan/work day=125 yuan, its girth member 3 be batch machining, can turnover rate high, stair amount is more, and its actual cost is lower afterwards in amortization, and every # stair are about about 50 yuan.
Comprehensive every # stair are cost-saving about 1650 yuan.
