Abstract
The utility model provides a slot type stair timber formwork, belonging to a formwork used for stair construction. The Slot type stair timber formwork comprises a bottom formwork, a pair of side formworks and a plurality of step baffle plates. The slot type stair timber formwork is characterized in that each side formwork consists of an outer side formwork and an inner side formwork in an overlapping and splicing way; a plurality of slots are formed in each inner side formwork; the height and the width of each slot are the same with the height and the thickness of each step baffle plate respectively; a space between each two adjacent slots is equal to the step width of a stair; a pair of the side formworks is symmetrically arranged on two sides of the bottom formwork; and two ends of each step baffle plate are connected with a pair of the side formworks in an insertion way through the slots. With the adoption of the slot type stair timber formwork, each side formwork consists of the outer side formwork and the inner side formwork in the overlapping and splicing way, so that the structure strength is greater and greater side pressure during the construction process can be born; due to the adoption of insertion connection between the step baffle plate and the side formworks, not only is the operation simpler than the traditional iron wire binding way, but also the damage to the formwork is difficultly caused during the removal; and therefore, the turnover times of the whole stair timber formwork are increased and the cost is further saved.
Description
Technical field
The utility model belongs to the template of using in the stair construction, refers to particularly a kind of insertion slot type stair wooden form.
Background technology
The wooden form that uses in the construction of tradition stair all adopts the thick template of 18mm, and its reinforcement measure adopts the iron wire colligation to reinforce usually.Yet, in the job site before the stair pouring concrete, stair template is in vacant state, very power is large in side pressure during pouring concrete, add trampling of operating personnel in the work progress, often occur so run the phenomenons such as mould, displacement, not only affected the concrete presentation quality of stair, and the number of turnover of stair template is few, expense is high.
The utility model content
Technical problem to be solved in the utility model just provides a kind of insertion slot type stair wooden form, and its structural strength is large, use safety, and the number of turnover is many, cost saving.
For solving the problems of the technologies described above, a kind of insertion slot type stair wooden form that the utility model provides comprises soffit formwork, a pair of side template and some baffle plates of marking time, and its special feature is: described side template is made of outboard template and inner side template lap splice; Have some slots on the described inner side template, height and the thickness with the baffle plate of marking time is identical respectively with width for the height of slot, and the spacing of adjacent slot equals the tread run of stair; A pair of side template is symmetricly set in the soffit formwork both sides, pegs graft by slot and a pair of side template in the two ends of the baffle plate of respectively marking time.
Further, described soffit formwork, outboard template and inner side template are respectively the thick wooden plywood of 15 ~ 20mm.
Further, the described baffle plate of marking time is the thick deal board of 30 ~ 40mm.
Compared with prior art, the beneficial effects of the utility model are: side template is made of outboard template and inner side template lap splice, and its structural strength is larger, can bear larger lateral pressure in the work progress; Mark time between baffle plate and the side template and to adopt the mode of pegging graft, not only more traditional iron wire colligation mode operates simplyr, and is difficult for template is caused damage when removing, and makes the number of turnover of whole stair wooden form more, and then provides cost savings.

Fig. 2 is the structural representation of side template among Fig. 1.
Fig. 3 is the structural representation of inner side template among Fig. 2.
Among the figure: 1-soffit formwork, 2-side template (wherein: 2.1-outboard template, 2.2-inner side template, 2.3-slot), the 3-baffle plate of marking time.
The specific embodiment
Below in conjunction with accompanying drawing and a case history specific embodiment of the present utility model is described in further detail.
As shown in Figure 1 to Figure 3, a kind of insertion slot type stair wooden form of the present utility model comprises soffit formwork 1, a pair of side template 2 and some baffle plates 3 of marking time.Soffit formwork 1 adopts the thick two-sided phenolic aldehyde waterproof wooden plywood of 18mm to make, side template 2 is made of outboard template 2.1 and inner side template 2.2 lap splices, outboard template 2.1 and inner side template 2.2 also are the thick two-sided phenolic aldehyde waterproof wooden plywood of 18mm, 3 on the baffle plate of marking time is made by the thick deal board of 30mm, to guarantee its strength and stiffness.Wherein, have on the inner side template 2.2 and the identical slot 2.3 of baffle plate 3 quantity of marking time, the height of slot 2.3 is identical with the height of the baffle plate 3 of marking time, width be 30mm, with mark time the consistency of thickness of baffle plate 3.After whole stair wooden form was set up, a pair of side template 2 was symmetricly set in the both sides on the soffit formwork 1, pegged graft by slot 2.3 and a pair of side template 2 in the two ends of the baffle plate 3 of respectively marking time.
Insertion slot type stair wooden form of the present utility model is applicable to common straight shape cast-in-place concrete structure slabtype stairway construction, and stair bench width is not more than 1.5m.The process of utilizing this stair wooden form to carry out certain stair construction is roughly:
1.1) according to design drawing, soffit formwork 1, side template 2 and the baffle plate 3 of marking time carried out size setting-out and processing;
1.2) set up steel pipe scaffold, guarantee its rigidity, strength and stability, the process of setting up satisfies the scaffold building code requirement;
1.3) laying soffit formwork 1.Soffit formwork 1 adopts and the China fir a tree, used in making timber for boats of a 50mm * 100mm is set as keel along the every interval 20cm of soffit formwork 1 width;
1.4) installation side template 2.A pair of side template 2 is arranged symmetrically with, and guarantees that two inner side template 2.2 are relative.After 2 of side templates are located on the soffit formwork 1, nail on three wooden a tree, used in making timber for boats with the bench equal length at three positions, upper, middle and lower of a pair of side template 2, with control stair bench size suitable for reading.The keel of side template 2 adopt the China fir a tree, used in making timber for boats of two 50mm * 100mm, are installed in respectively the suitable for reading and end opening of side template;
1.5) installation " ［ " shape clamp.Adopt reinforcement fabrication " ［ " shape clamp is clipped in side template 2 both sides according to one meter one spacing, strengthens fixing between soffit formwork 1 and the side template 2.
1.6) baffle plate 3 of marking time is installed.After side template 2 installs and fixes, coat the wooden form special separating agent in the wiping groove 2.3 of side template 2, insert in corresponding two slots 2.3 at the two ends of the baffle plate 3 of then directly will marking time, and the baffle plate 3 of marking time after guaranteeing to insert is tight with side template 2 combinations;
1.7) bracing reinforcement.Scaffold support system is reinforced, measured simultaneously the absolute altitude of 1 of soffit formwork and baffle plate 3 end faces of marking time, under the prerequisite that guarantees the staircase structure absolute altitude, reinforce the stair template support system, with the rigidity that satisfies scaffold, the requirement of strength and stability.
After the stair casting and constructing was finished, the process of the dismounting of the utility model template was roughly:
2.1) above-mentioned " ［ " shape clamp of dismounting;
