Abstract

The utility model discloses a sleeve preserving and pre-burying system belonging to the technical field of architectural construction. The sleeve preserving and pre-burying system comprises a sleeve, a handle, a closure plate, flat irons and angle steels. The handle is located at one end of the sleeve; the closure plate is located between the sleeve and the handle; and the flat irons and the angle steels are fixed on the template. The utility model has the advantages that the positioning accuracy rate is high, the fixing is firm, the position is not easy to move, the hole-maintenance and hole-opening frequency is decreased, and the rework cost is reduced; the construction is convenient and the mounting rate is high; the occupied area and the influence on the civil construction steel bars are small; the closure effect is good so that the concretes can not enter the sleeve; the material source is rich; the short steel bars are waste civil construction materials, and the angle steels and the flat irons are leftover materials in the project; when in dismantling, only the sleeve is pulled out and the cross fixing rack is dismantled, so the dismantling is convenient.

Description

Sleeve pipe set aside pre-embedded system

Technical field

The utility model belongs to technical field of building construction, is specifically related to a kind of sleeve pipe set aside pre-embedded system.

Background technology

In the structure construction stage, all kinds of piping erection does not mostly possess execution conditions, therefore just must carry out the set aside pre-embedded work of hole, sleeve pipe, and most of project casing construction methods are that iron wire is fixed colligation all around.Find that in construction this kind method has some constructional difficulties:

1), reserved location is inaccurate: iron wire to around fixedly the time, the center is looked for inaccurate, sleeve pipe put do not stay just easily flat;

2), the finished product protection difficulty: during fluid concrete, even bump easily askew, bump tiltedly and bump.

The utility model content

The utility model is in order to solve in the structure construction stage, and all kinds of piping erection does not mostly possess execution conditions, finds some constructional difficulties in construction:

2), the finished product protection difficulty: during fluid concrete, even bump easily askew, bump tiltedly and bump;

In order to overcome the above problems, the utility model has adopted a kind of sleeve pipe set aside pre-embedded system.

The utility model comprises sleeve pipe, handle, closure plate, band iron and angle steel, and described handle is positioned at an end of sleeve pipe, and described closure plate is between described sleeve pipe and handle, and described band iron and angle steel are fixed on the template.

Bolt hole is left in the centre position of described closure plate.

Described band iron and angle steel are fixed into cross, and described casing pipe sleeve is on described cross, and angle steel and band iron are fixed into round steel of the vertical welding of planar central of cross.

On the described round steel screw thread is arranged.

The nail hole is left at the two ends of described band iron and angle steel respectively.

The utlity model has following beneficial effect: there is following advantage in the sleeve pipe set aside pre-embedded system that the utility model provides:

1), the locating accuracy height, fixation is not easy the shift position, can reduce the frequency of repairing the hole, punching, and reduces rework cost;

2), easy construction, the installation effectiveness height;

3), floor space is little, and is little to the influence of civil engineering reinforcing bar;

4), plugging effect is good, do not worry that concrete enters in the sleeve pipe;

5), the material therefor source is abundant: used bar dowel can be used the civil engineering waste material, and angle steel and band iron use leftover pieces remaining in the engineering;

6), remove conveniently, only need to pull out sleeve pipe during dismounting and tear the cross fixed mount open.

Fig. 2 makes center fixation cross schematic diagram for the utility model;

Fig. 3 is the stereogram of the utility model Fig. 2;

Fig. 4 is the utility model installation schematic diagram.

Fig. 5 removes schematic diagram for the utility model.

The specific embodiment

The utility model will be further described below in conjunction with accompanying drawing.Concrete job practices is as follows:

1), make sleeve pipe: welded steel pipe or seamless steel pipe are cut into the length that we need, the handle of burn-oning in the upper end, and carry out shutoff with iron sheet or iron plate, the bolt hole of φ about 10 is stayed at the center, as shown in Figure 1, Fig. 1 cuts off in the utility model to manage schematic diagram.

2), make the center fixation cross: one section band iron and angle steel are pressed the blanking of casing inner diameter length, be vertically welded in together, at vertical angle steel and round steel that is with screw thread of band iron planar central welding, as shown in Figure 2, Fig. 2 makes center fixation cross schematic diagram for the utility model again.

3), " four nails are determined the course of events ": according to drawing or in-depth figure, the center of sleeve pipe is marked on the template, and the sleeve pipe center of circle with the center alignment tab of cross is fixed on band iron and angle steel on the template respectively with iron nail, as shown in Figure 3, Fig. 3 is the stereogram of the utility model Fig. 2.

4), sleeve pipe installs: with casing pipe sleeve on cross, first-class bolt, as shown in Figure 4, Fig. 4 is the utility model installation schematic diagram.

5), sleeve pipe is removed: when treating that civil engineering has been broken concrete, bolt is laid down, extracted sleeve pipe, pull out cross, prepare next time and use.
