Abstract
The utility model discloses a construction tool for stair step exposed corners and water retaining lines. The construction tool comprises a top plate (1) and a side plate (2), wherein the side plate (2) is fixedly connected to one side of the top plate (1); a through groove (4) is formed on the bottom surface of the top plate (1); the through groove (4) clings to the side plate (2) and is in parallel with the side plate (2). With use of the construction tool disclosed by the utility model, the water retaining lines and the stair exposed corners can be directly constructed on a stair step building surface layer by using cement mortars; the construction tool is simple in process and convenient to construct; additionally, finished water retaining lines and stair exposed corners are reliable in quality, and also artistic and elegant.
Description
Technical field
The utility model relates to a kind of stair step external corner and dash line construction tool, belongs to concrete staircase construction tool technical field.
Background technology
Along with the raising of people's quality of the life, the requirement of the security performance of the aesthetic measure of people to residence match facility and use is also more and more higher.Therefore, mark time external corner and dash line requirement reliable in quality and elegant in appearance of civilian construction building.Traditional method is to adopt first hem strip to make dash line at stair step external corner edge again, the method is time-consuming taking a lot of work not only, and the cost dropping into is also large, more cause the waste of hem strip material, and the construction of dash line and the external corner side letter out of marking time will carry out step by step, directly cause the increase of labour and cost.In order to overcome above-mentioned deficiency, at present, adopt ceramic tile to be attached to more and on limit, concrete building ladder rung side, make stair step external corner and dash line.But adopt the shortcoming of ceramic tile as follows: first, buy ceramic tile and need disposable a large amount of inputs, construction cost is high, does not meet energy-conservation requirement; In addition, ceramic tile veneer trouble, construction quality is difficult to ensure, and easily produce loose or dislocation, the phenomenon such as break, impact is used function, easily causes potential safety hazard.
Summary of the invention
The purpose of this utility model is: a kind of simple in structure, easy construction is provided, and can directly in the time of the building coats construction of stair step, synchronously makes the construction tool of stair step external corner and dash line, to overcome the deficiencies in the prior art.
The utility model is to form like this: a kind of stair step external corner and dash line construction tool, comprise top board and side plate, and side plate is fixedly connected on top board one side, is provided with a groove in the bottom surface of top board, and this groove is close to side plate and parallel with side plate.
Described top board and side plate adopt A3 steel to do, and side plate is vertically welded in top board one side.
On described top board, be welded with handle.
The gate that described handle adopts A20 round steel or square tube to be bent into, handle is welded on top board central authorities perpendicular to side plate direction.
Compared with prior art, the utility model has the advantage of: adopt the utility model directly to smooth out with the fingers dash line and stair external corner in stair step building coats cement mortar, operation is simple, easy construction, and finished product dash line and stair external corner reliable in quality and elegant in appearance, both reduced construction cost, improve again construction efficiency, avoid potential safety hazard simultaneously, reached the requirements such as energy-conserving and environment-protective.

Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is described in further detail.
Embodiment of the present utility model: referring to Fig. 1, a kind of stair step external corner of the present utility model and dash line construction tool, comprise top board 1 and side plate 2, and side plate 2 is fixedly connected on top board 1 one sides, be provided with a groove 4 in the bottom surface of top board 1, this groove 4 is close to side plate 2 and parallel with side plate 2.Described groove 4 groove widths are 50mm, and groove depth D is 10mm, and the outer back gauge top board of groove 4 lateral surface C is 20mm.Described top board 1 and side plate 2 adopt A3 steel to do, and side plate 2 is vertically welded in top board 1 one sides.Wherein top board 1 is consistent with the length of side plate 2, and length L is 100mm, and the width W of top board 1 is 80mm, and side plate 2 height H are 70mm; The thickness B of side plate is 10mm, and the thickness A of top board is 30mm.On described top board 1, be welded with handle 3, described handle 3 adopts the A20 round steel of 10mm or the gate that 10 × 10 × 2mm square tube is bent into, and handle 3 is welded on top board 1 central authorities perpendicular to side plate direction.
Construction sequence of the present utility model is as follows:
Step 1, according to designing requirement, stair step height and width are carried out to bracing wire and find size accurately, guarantee that stair step size meets design and code requirement.Adopt the dry cement mortar that match ratio is 1: 2 to carry out stair step surface construction.Lay cement mortar along the length direction of marking time, lay height a little more than given size line, and strike off with floating rule, after surface layer moisture is slightly dry, polish with wood float.
Step 2, polish after, use immediately the cement mortar uniform spreading that mixes up match ratio on stair step railing limit, lay height and must not be less than 15mm, referring to Fig. 2 and Fig. 3, adopt instrument of the present utility model repeatedly to drag back and forth mark time external corner 5 and dash line 6 are smoothed out with the fingers to line for the first time, when operation, need prepare that clear water cleans instrument and wetting.Smooth straight for ensureing dash line 6, while smoothing out with the fingers line, instrument two ends are concordant with the portion of playing of marking time all the time, and above-mentioned construction is mainly to carry slurry as chief commander mark time external corner 5 and 6 moulding of dash line.
Before step 3, cement mortar initial set, carry out second time press polish, the object of press polish is that whole marking time received to optical pressure in fact, must not leak pressure, repairs for mark time external corner 5 and dash line 6 edge corner angle burrs, scarce limit simultaneously.
Step 4, before cement mortar final set, use instrument of the present utility model to carry out last press polish finishing, when operation, need firmly smear pressure, during second time press polish, stay smear line, pore is floating, make to mark time external corner 5 and dash line 6 are straight, smooth, hard.
Step 5, intensity for ensureing to mark time after perception and the moulding of external corner 5 and dash line 6, the maintenance of sprinkling water in second day after the surface construction of marking time completes, curing time is no less than 7 days.
By above improvement make to mark time external corner 5 and dash line 6 lines straight, smooth, firm, attractive in appearance, greatly improve construction effect, reduced construction cost, provided quality goods or brilliant and created good condition for engineering, in the practicality in later stage, reduce and reprocessed, avoided the generation of contingency simultaneously.
