Abstract

The utility model discloses a floor slab provided with flat pipes. The floor slab comprises a prefabricated layer and a cast-in-place layer; a truss with a part extending out relative to the upper surface of the prefabricated layer is pre-embedded in the prefabricated layer, and the extending part of the truss is positioned in the cast-in-place layer; the prefabricated layer with be equipped with flat pipe between the main muscle of truss, the height of flat pipe cross section is 10-15 mm, and the width of this flat pipe cross section is greater than its height. The utility model solves the problem that the steel content and the thickness of the floor slab are increased due to the existing round pipe, and saves the cost.

Description

Floor with flat pipe

Technical Field

The utility model belongs to the field of building industrialization, and particularly relates to a floor slab provided with flat pipes.

Background

At domestic current assembled, the pre-buried water and electricity spool of floor all need expose the truss part at the superimposed sheet and pass, and current water and electricity spool all is the pipe, and the truss installation has the error to lead to the spool to pass very hardly slightly, needs the manual work to prize the truss, and for satisfying the poling needs, the height of truss is generally higher, highly needs 20mm at least of the relative superimposed layer stretching out, and then leads to floor steel content and floor thickness to increase.

SUMMERY OF THE UTILITY MODEL

The utility model aims to provide a floor with flat pipes, which aims to solve the technical problem that the steel content and the thickness of the floor are increased due to round pipes.

In order to achieve the purpose, the specific technical scheme of the utility model is as follows:

a floor with flat tubes comprises a prefabricated layer and a cast-in-place layer; a truss with a part extending out relative to the upper surface of the prefabricated layer is pre-embedded in the prefabricated layer, and the extending part of the truss is positioned in the cast-in-place layer; the prefabricated layer with be equipped with flat pipe between the main muscle of truss, the height of flat pipe cross section is 10-15 mm, the width of flat pipe cross section is greater than its height.

Therefore, the utility model adopts the flat pipe to replace the round pipe, designs the corresponding size, and under the condition of meeting the area, the height of the cross section of the flat pipe is 5-10mm lower than that of the cross section of the round pipe used at present, thereby solving the problem of increased steel content caused by the increase of the truss height due to the meeting of truss pipe penetration, and also solving the problem of thickened floor slab caused by the increase of the truss height due to the meeting of truss pipe penetration.

Preferably, the width of the cross section of the flat tube is 20-30 mm.

Preferably, the flat tube is a hollow rectangular tube.

The utility model has the following advantages:

1. the water and electricity conduit can freely penetrate through the truss;

2. the thickness of a cast-in-place layer is reduced, and the self weight of the floor slab is further reduced;

3. the net height of the floor is increased;

4. the steel content of the laminated slab is reduced;

5. the cost of the floor slab is saved.

Drawings

Fig. 1 is a schematic cross-sectional view of a floor slab with flat tubes according to the present invention.

The notation in the figure is:

1. a truss; 2. a cast-in-place layer; 3. flat tubes; 4. prefabricating a layer; 5. and (5) main ribs.

Detailed Description

For a better understanding of the objects, structure and function of the utility model, reference should be made to the following detailed description taken in conjunction with the accompanying drawings.

As shown in fig. 1, the floor slab with flat tubes disclosed in this embodiment includes a prefabricated layer 4 and a cast-in-place layer 2. Truss 1 with part extending out relative to the upper surface of the prefabricated layer is pre-embedded in the prefabricated layer 4, and the extending part of the truss 1 is positioned in the cast-in-place layer 2. Flat tubes 3 are arranged between the prefabricated layer 4 and the main ribs 5 of the truss 1, the height of the cross section of each flat tube 3 is 10-15 mm, the width of the cross section of each flat tube 3 is larger than the height of the cross section of each flat tube 3, and generally speaking, the width of the cross section of each flat tube 3 is 20-30 mm.

In addition, flat pipe 3 is the hollow rectangular pipe, can avoid rocking when cast-in-place. If necessary, the flat tubes 3 can also be fixed to the truss 1 by means of binding or other means.

This embodiment becomes flat pipe by traditional pipe through the water and electricity spool with pre-buried in the floor for pre-buried water and electricity spool can be light pass the truss, has reduced the height of truss, thereby reaches the thickness that reduces cast-in-place layer 2, has alleviateed the floor dead weight, has reduced superimposed sheet steel content, thereby reaches the purpose of sparingly building cost.

It is to be understood that the present invention has been described in terms of the preferred embodiment, and that various changes, modifications, and equivalents may be made to these features and embodiments by those skilled in the art without departing from the spirit and scope of the utility model. In addition, many modifications may be made to adapt a particular situation or material to the teachings of the utility model without departing from the essential scope thereof. Therefore, it is intended that the utility model not be limited to the particular embodiment disclosed, but that the utility model will include all embodiments falling within the scope of the appended claims.
