The utility model discloses a form that steel wood combines, effective material saving cost, convenience, reduction of erection time are demolishd in the installation, template repeatedly usable, template rigidity is good, and the installation accuracy is high, can effectively guarantee effect after the stair shaping.
Description
Technical field
The utility model belongs to field of electricity construction, especially a kind of stair tread formwork of installing middle bracing means.
Background technology
Traditional wooden form stair construction method is fixed broadstep by iron nail, iron wire etc., install, remove operation loaded down with trivial details, the number of turnover is few; Cross section size not easily ensures; Flitch, template loss are larger; Sizing punching block stair template, employing shaped steel, Plate Welding are processed into stair template, effectively can ensure the sectional dimension of stair; Need tower crane to coordinate lifting during construction, use position to have limitation; Disposable input shaped steel, steel plate amount are comparatively large, and cost is higher.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art part, the stair tread formwork of bracing means in the middle of the installation providing a kind of structure simple, reasonable in design, easy to use, reliability and durability.
The utility model solves its technical problem and takes following technical scheme to realize:
Install a stair tread formwork for middle bracing means, stair stair tread formwork comprises riser template and side stand, is fixedly mounted with multiple riser template uniformly at intervals, it is characterized in that: riser template lateral separation is uniform between the side stand of both sides; The angle steel keel that two relative spacings are arranged longitudinally are installed in the middle part of the multiple riser templates between the side stand of both sides, two angle steel keel corresponding outside the plurality of riser template are all provided with a bracing means;
Bracing means concrete structure comprises support angle bar, bracket, upper adjusting rod, nut and lower dolly bar, support angle bar contact riser template bottom, a bracket is vertically fixed with in support angle bar upper end, vertically weld in bracket upper end and be fixed with adjusting rod on, on this, adjusting rod is shaped with external screw thread, upper adjusting rod is upward through the gap between angle steel keel, and engagement is provided with nut on upper adjusting rod; A lower dolly bar is coated with in support angle bar lower, transverse.
And the installation site of corresponding riser template is all shaped with embedding slot on side stand.
And upper adjusting rod has been installed in series two nuts.
And side stand is wooden keel and shear wall keel bracket.
Advantage of the present utility model and good effect are:
1, the angle steel keel in the utility model are main stressed members of intermediate retainer, are transmitted by adjusting rod, bear the horizontal force expanded from riser template when building, and then improve formwork rigidity.
2, the utility model adopts the form that steel wood combines, and effectively saves material cost; Assembling and disassembling is convenient, the reduction of erection time; Template is reusable; Formwork rigidity is good, and installation accuracy is high, effectively can ensure the shaping rear effect of stair.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
Fig. 2 is the top view of Fig. 1;
Fig. 3 is the schematic enlarged-scale view of single bracing means.
Detailed description of the invention
Below in conjunction with accompanying drawing, also by specific embodiment, the utility model is described in further detail, and following examples are descriptive, are not determinate, can not limit protection domain of the present utility model with this.
A kind of stair tread formwork of installing middle bracing means, stair stair tread formwork comprises riser template 3 and side stand 4, side stand is wooden keel and shear wall keel bracket, two side stands tilt to be fixed on construction location, between the side stand of both sides, be fixedly mounted with multiple riser template uniformly at intervals, the plurality of riser template is used for the step side riser of the location stair when constructing.
In order to fixing riser template, on side stand, the installation site of corresponding riser template is all shaped with embedding slot.
Innovative point of the present utility model is:
In order to verticality and the rigidity of the stair template that tightens control, be described with direction shown in accompanying drawing 2, the long plate structure of riser template longitudinal direction, riser template lateral separation is uniform; Longitudinally install the angle steel keel 1 that two relative spacings are arranged in the middle part of multiple riser templates between the side stand of both sides, these two angle steel keel are provided with multiple bracing means 2 uniformly at intervals, and the plurality of bracing means is adjacent to outside a riser template respectively;
Bracing means concrete structure is see shown in accompanying drawing 3, comprise and support angle bar 24, bracket 23, upper adjusting rod 21, nut 22 and lower dolly bar 25, support angle bar contact riser template bottom, a bracket is vertically fixed with in support angle bar upper end, vertically weld in bracket upper end and be fixed with adjusting rod on, on this, adjusting rod is shaped with external screw thread, and upper adjusting rod is upward through the gap between angle steel keel, and engagement is provided with nut on upper adjusting rod; In order to strengthen two nuts that adjusting rod has been installed in series fastening force, nut and bracket clamp angle steel keel thus bracing means and angle steel keel are fixed;
Prevent distortion in order to strengthen to the support force of riser template bottom, be coated with a lower dolly bar 25 in support angle bar lower, transverse, this lower dolly bar is Φ 14 harness cord screw rod, rotates lower dolly bar and can strengthen the firm thrust of riser template.
The riser model sheetinstallat precision ± 2mm of the present embodiment.
Although disclose embodiment of the present utility model and accompanying drawing for the purpose of illustration, but it will be appreciated by those skilled in the art that: in the spirit and scope not departing from the utility model and claims, various replacement, change and amendment are all possible, therefore, scope of the present utility model is not limited to the content disclosed in embodiment and accompanying drawing.
