Description

Cast-in-situ stair tread arc external corner mold

Technical Field

The utility model relates to a stair mold, in particular to a cast-in-situ stair tread arc external corner mold.

Background

The design of wall details of the cast-in-situ reinforced concrete high-rise building is important in construction, and the stepping stairs are one of the parts with quality not easy to guarantee in construction; in the construction of traditional cast-in-place concrete stairway, the intersection angle of the tread and the kicking surface of the formed stairway section is 90-degree external angle, and the corner is broken due to collision when the shuttering is removed and the later construction is used. The existing advanced technology adopts the iron trowel with round corners to smear round the external corners to form circular arcs when the surface is collected after the concrete pouring of the stair is finished, but the operation mode has large workload and low efficiency, and is not beneficial to unified management of engineering.

Disclosure of Invention

In order to solve the technical problems, the technical scheme provided by the utility model is as follows: the utility model provides a cast-in-situ stair step circular arc external corner mould, includes cope match-plate pattern, lower bolster, the lower bolster joint is in cope match-plate pattern bottom and suits with the cope match-plate pattern shape, the outside extension of cope match-plate pattern other end forms first horizontal plate, be provided with the filler between first horizontal plate and the cope match-plate pattern lateral wall, the filler bottom is the arc surface of inwards sunken.

Compared with the prior art, the utility model has the advantages that: the utility model can effectively reduce damage during and after die removal by arranging the arc angle, is beneficial to protecting finished products of steps, can improve the once survival rate of external corners of cast-in-place concrete stair steps, can be directly cast and molded, avoids subsequent reprocessing, and reduces the workload.

Detailed Description

For the purpose of making the objects, technical solutions and advantages of the embodiments of the present utility model more apparent, the technical solutions of the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model, and it is apparent that the described embodiments are some embodiments of the present utility model, but not all embodiments of the present utility model. The components of the embodiments of the present utility model generally described and illustrated in the figures herein may be arranged and designed in a wide variety of different configurations.

In the description of the embodiments of the present utility model, it should be noted that, if the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. indicate an azimuth or a positional relationship based on that shown in the drawings, or an azimuth or a positional relationship in which the product of the present utility model is conventionally put when used, it is merely for convenience of describing the present utility model and simplifying the description, and it does not indicate or imply that the apparatus or element to be referred to must have a specific azimuth, be configured and operated in a specific azimuth, and thus should not be construed as limiting the present utility model. Furthermore, the terms "first," "second," "third," and the like are used merely to distinguish between descriptions and should not be construed as indicating or implying relative importance.

Furthermore, the terms "horizontal," "vertical," "overhang" and the like, if any, do not denote a requirement that the component be absolutely horizontal or overhang, but rather may be slightly inclined. As "horizontal" merely means that its direction is more horizontal than "vertical", and does not mean that the structure must be perfectly horizontal, but may be slightly inclined.

In the description of the embodiments of the present utility model, "plurality" means at least 2.

In the description of the embodiments of the present utility model, it should also be noted that, unless explicitly specified and limited otherwise, the terms "disposed," "mounted," "connected," and "connected" should be construed broadly, and may be, for example, fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; can be directly connected or indirectly connected through an intermediate medium, and can be communication between two elements. The specific meaning of the above terms in the present utility model can be understood by those of ordinary skill in the art according to the specific circumstances.

Example one (Wood form)

The cast-in-situ stair tread arc external corner mold comprises an upper mold plate 1 and a lower mold plate 2, wherein the lower mold plate 2 is clamped at the bottom of the upper mold plate 1 and is adaptive to the shape of the upper mold plate 1, the other end of the upper mold plate 1 extends outwards to form a first horizontal plate 3, a filling block 4 is arranged between the first horizontal plate 3 and the side wall of the upper mold plate 1, and the bottom of the filling block 4 is an inward concave arc surface 5; the upper template 1 comprises a second horizontal plate 101 which is positioned on the same horizontal plane with the first horizontal plate 3, and two ends of the second horizontal plate 101 are respectively provided with a first vertical plate 102, so that a buckling groove 103 is formed between the first vertical plate 102 and the second horizontal plate 101, and the lower template 2 corresponds to the buckling groove 103; the lower template 2 comprises a main template 201 inserted into the buckling groove 103, and a side module 202 is arranged on one side of the main template 201 away from the arc surface 5; the upper template 1 and the lower template 2 are made of wood.

Example two (aluminium template)

Referring to fig. 2, the upper template 1 includes a third horizontal plate 104 at the same horizontal plane as the first horizontal plate 3, and a second vertical plate 105 is downwardly disposed at one end of the third horizontal plate 104 near the first horizontal plate 3, so that an open slot is formed between the second vertical plate and the third horizontal plate 104, and the lower template 2 is an L-shaped template corresponding to the open slot; the upper template 1 and the lower template 2 are aluminum materials; the upper and lower templates 1 and 2 are bonded by wire bonding or adhesive bonding.

When the method is specifically implemented, the arc angle is arranged, so that damage during and after form removal can be effectively reduced, finished product protection of steps is facilitated, the primary survival rate of cast-in-place concrete stair step external angles can be improved, and direct casting and forming can be realized.
