Abstract
The utility model discloses a casing pipe used for a pipeline prepared hole, which is convenient to demould and plug. The casing pipe used for the pipeline prepared hole is characterized by comprising a cone cylinder (1) provided with a handle (6), wherein the cone cylinder (1) is provided with a positioning device. The casing pipe used for the pipeline prepared hole has the advantages of simple structure and low cost and is convenient to demould. The operation of demoulding can be carried out after concrete is solidified, no footprints are left on a floor, and repeated labor of trowelmen is avoided. Because the casing pipe is tapered, lateral reinforcing steel bars do not need to be added during plugging, and cement blocks can not fall.
Description
Technical field
The utility model relates to a kind of building operations mould, and specifically a kind of pipeline preformed hole is used sleeve pipe.
Background technology
In the building operations, need pipeline preformed hole holes such as supplying drainage, Gas Pipe usually.The most frequently used method has two kinds: a kind of sleeve pipe that is processed into by steel pipe that is to use; Sleeve pipe is provided with handle and pricks silk, earlier with nailing on four location nails on the masterplate, is wrapped in four location and nails on sleeve pipe is fixed on the masterplate pricking silk again during installation; Do not only expense material like this, use also inconvenient.Because sleeve pipe is a cylindrical drum, therefore, before concrete setting, just must take out sleeve pipe, like untimely taking-up; To be difficult to after the concrete setting take out again, if but before concrete does not solidify, get, can stay many footmarks to appearance unavoidably; Make bricklayer's smooth footmark of recruitment again, cause the duplication of labour, because sleeve pipe is not provided with cover plate; Concrete is easy to get in the sleeve pipe, often needs the workman that concrete is drawn out, and has increased working strength of workers.And, because pipeline is vertical with reserving hole, also need add the problem that transverse reinforcement prevents that cement block from dropping during shutoff, not only take material, operation is also inconvenient; Two kinds are to use the foam block by the adhesive tape wrapping, and foam block is provided with pricks silk, locate nail on four on the masterplate for nail earlier during installation; Be wrapped in four location and nail on foam block is fixed on the masterplate pricking silk again, foam block can not completely take out after concrete setting usually, can't recycle; Not environmental protection, and must batter down foam soon the cleaning hole before the piping erection; Foam in small, broken bits is wind blown completely all to be to influence construction environment.
Summary of the invention
The purpose of the utility model provide a kind of demoulding, shutoff easily pipeline preformed hole use sleeve pipe.
The utility model is to adopt following technical scheme to realize its goal of the invention, and a kind of pipeline preformed hole is used sleeve pipe, and it comprises the awl tube that handle is installed, and the awl tube is provided with positioner.
The positioner of the utility model comprises the base plate that is installed in the awl tube bottom, and base plate is provided with locating hole.
The utility model falls in the awl tube for preventing concrete, and said awl tube top is provided with the cover plate that is used to cover the awl tube.
The described awl tube of the utility model is a plastic material.
Because adopt technique scheme, the utility model has been realized goal of the invention preferably, it is simple in structure; Cost is low, is convenient in demoulding, and can wait until the demoulding after the concrete setting; Flooring can not stay footmark, avoids bricklayer's duplication of labour, because sleeve pipe is a conical design; Therefore, need not to increase transverse reinforcement during shutoff, cement block can not drop yet.
Description of drawings
Fig. 1 is the structural representation of the utility model.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described further.
Can be known that by Fig. 1 a kind of pipeline preformed hole is used sleeve pipe, it comprises the awl tube 1 that handle 6 is installed, and awl tube 1 is provided with positioner.
The positioner of the utility model comprises the base plate 2 that is installed in awl tube 1 bottom, and base plate 2 is provided with locating hole 3.
The utility model falls in the awl tube 1 for preventing concrete, and said awl tube 1 top is provided with the cover plate 5 that is used to cover awl tube 1.
The described awl tube 1 of the utility model is a plastic material.
Make the step of pipeline preformed hole through the utility model:
⑴ install: at first, on the pairing template in the position of need preformed hole, hole, then screw 4 is installed in the locating hole 3 on the awl tube 1, and last, screw 4 is installed in awl tube 1 is fixed on the template;
⑵ cast: fluid concrete on template, owing to be stamped cover plate 5 on the awl tube 1, therefore, in the process of cast, concrete can not fall in the awl tube 1;
⑶ the demoulding: 6 will bore tube and 1 from concrete, take out through shaking hands, and because awl tube 1 is the taper setting, therefore, take out after can waiting until concrete setting again, flooring can not stay footmark, avoids bricklayer's duplication of labour;
Because therefore the awl tube 1 of the utility model, need not to increase transverse reinforcement for the taper setting during shutoff in the end, cement block can not drop yet.
