It should be understood that the embodiments of this specification and the specific features in the embodiments are detailed descriptions of the technical solutions of the embodiments of this specification, rather than limitations on the technical solutions of this specification.

Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that the process, method, article or equipment including a series of elements includes not only those elements, but also includes other elements not explicitly listed, or also includes elements inherent to such process, method, article or equipment.

The term "more than two" includes two or more than two situations.

[0030] The following is based on the attached Figure 1-2 The floor slab trench structure 10 and the construction method thereof according to the embodiment of the present application are described.

[0031] like Figure 1As shown, the floor slab trench structure 10 according to the embodiment of the present application includes: a plurality of structural beams, a first steel truss floor deck 1 and a second steel truss floor deck 2.

[0032] A plurality of structural beams are arranged at intervals, the first steel truss floor deck 1 and the second steel truss floor deck 2 are both connected to the structural beams, and the first steel truss floor deck 1 and the second steel truss floor deck 2 are spaced apart and arranged opposite to each other; wherein a pipe trench 4 is defined between two adjacent structural beams, the first steel truss floor deck 1 and the second steel truss floor deck 2. The pipe trench 4 includes a groove for laying pipes.

[0033] Therefore, the pipe trench 4 can be defined by using two adjacent structural beams, the first steel truss floor deck 1 and the second steel truss floor deck 2. In this way, the first steel truss floor deck 1 replaces the bottom plate of the pipe trench 4, thereby eliminating the need to adopt a hanging formwork construction plan, which is beneficial to improving construction efficiency and reducing safety hazards.

[0034] For example, the first steel truss floor deck 1 and the second steel truss floor deck 2 can be arranged relative to each other in the height direction, and concrete can be poured on the first steel truss floor deck 1 so that a steel truss floor deck and its floor distribution bars and additional connecting steel bars and concrete form a first steel truss concrete floor 11, and concrete can also be poured on the second steel truss floor deck 2 so that the second steel truss floor deck 2 and its floor distribution bars and additional connecting steel bars and concrete form a second steel truss concrete floor 21, and the second steel truss concrete floor 21 is provided with a building surface layer 23 on the side away from the first steel truss floor deck 1.

[0035] For example Figure 1 As shown, the second steel truss floor deck 2 is located above the first steel truss floor deck 1, and a plurality of structural beams are connected between the first steel truss floor deck 1 and the second steel truss floor deck 2 to support the second steel truss floor deck 2. The structural beams may be connected to the first steel truss floor deck 1 and / or the second steel truss floor deck 2 via bolts 8.

[0036] Among them, a plurality of structural beams can be arranged at intervals along the length direction and / or width direction of the second steel bar truss floor deck 2, so that a pipe trench 4 is defined between two adjacent structural beams, the first steel bar truss floor deck 1 and the second steel bar truss floor deck 2. In this way, the design of the pipe trench 4 does not need to adopt a construction scheme of a hanging formwork, which is conducive to improving construction efficiency and reducing safety hazards.

[0037] According to the floor slab trench structure 10 of the embodiment of the present application, the first steel truss floor deck 1 and the second steel truss floor deck 2 are arranged opposite to each other; the structural beam is connected between the first steel truss floor deck 1 and the second steel truss floor deck 2, and a plurality of structural beams are arranged at intervals; wherein, a trench 4 is defined between two adjacent structural beams, the first steel truss floor deck 1 and the second steel truss floor deck 2, so that the first steel truss floor deck 1 can be used to replace the bottom plate of the trench 4, thereby eliminating the need to adopt a hanging formwork construction scheme, which is beneficial to improving construction efficiency and reducing safety hazards.

[0038] In some embodiments, Figure 1 As shown, the structural beam includes an I-beam 3 , and the first steel bar truss floor deck 1 is connected to the lower wing plates 31 of two adjacent I-beams 3 on one side facing the upper wing plates 32 .

[0039] Therefore, the lower wing plate 31 of the I-beam 3 can support the first steel truss floor deck 1 to enhance the structural stability of the first steel truss floor deck 1 and reduce the difficulty of connecting the first steel truss floor deck 1 with the I-beam 3.

[0040] In some embodiments, Figure 1 As shown, the floor trench structure 10 further includes a casting 5 , which is located in the trench 4 and connected to the web 33 of the I-beam 3 , and the side of the casting 5 facing away from the web 33 forms a side wall of the trench 4 .

[0041] It is understandable that the casting 5 can be formed by casting concrete on site, and thus, the casting 5 can be used to form the side wall of the trench 4, so that the side wall of the trench 4 is relatively flat, which is conducive to reducing the difficulty of routing the pipeline and can play a certain sealing role on the trench 4.

[0042] In some embodiments, the difference between the minimum distance from the casting 5 to the web 33 and the maximum distance from the upper wing 32 to the web 33 is greater than or equal to 50 mm. Figure 1 As shown, the difference between the minimum distance between the casting 5 and the web 33 and the maximum distance between the upper wing plate 32 and the web 33 is L, and L≥50mm. For example, L=50mm, or L=52mm, or L=55mm, or L=56mm, or L=60mm, that is, the value of L meets the above value range, so that the wall thickness of the side wall of the pipe trench 4 can be guaranteed to be within a reasonable range, avoiding damage caused by too small wall thickness of the side wall of the pipe trench 4.

[0043] In some embodiments, Figure 1As shown, the floor slab trench structure 10 further includes: an electromechanical bracket 6 and a first mounting member 61, the electromechanical bracket 6 is used to fix the electromechanical equipment, the first mounting member 61 is located in the trench 4, and the first mounting member 61 is provided on the first steel truss floor deck 1 and / or the second steel truss floor deck 2, and the electromechanical bracket 6 is connected to the first mounting member 61. Thus, the electromechanical bracket 6 can be fixed in the trench 4 by the first mounting member 61, so as to reduce the difficulty of setting the electromechanical bracket 6.

[0044] In some implementations, the first mounting member 61 may be pre-buried on the surface of the first steel bar truss floor deck 1 facing the pipe trench 4 (eg, Figure 1 The upper surface of the first steel truss floor deck 1 in the embodiment of the present invention), and / or the first mounting member 61 can be pre-buried in the surface of the second steel truss floor deck 2 facing the pipe trench 4 (such as Figure 1 In this way, the first mounting member 61 is provided in a pre-embedded manner to reduce the difficulty of providing the first mounting member 61, and the electromechanical support 6 can be directly fixed to the first mounting member 61, thereby reducing the difficulty of providing the electromechanical support 6.

[0045] In some embodiments, Figure 1 As shown, the floor slab trench structure 10 further includes a cover plate 7 , the second steel truss floor deck 2 is provided with an opening 201 , the opening 201 is communicated with the trench 4 , and the cover plate 7 is connected to the second steel truss floor deck 2 and is used to block the opening 201 .

[0046] Therefore, by setting the opening 201, it is convenient to inspect the pipeline in the trench 4 through the opening 201, which is helpful to reduce the difficulty of pipeline inspection, and by setting the cover plate 7, the cover plate 7 can be movably connected to the second steel truss floor deck 2, so that the opening 201 can be opened or closed through the cover plate 7.

[0047] In some embodiments, Figure 1 As shown, the floor slab trench structure 10 further includes: a second mounting member 71, the second mounting member 71 is arranged on the second steel bar truss floor deck 2, and the cover plate 7 is connected to the second mounting member 71. Therefore, the cover plate 7 can be fixed to the second steel bar truss floor deck 2 by the second mounting member 71, so as to reduce the difficulty of setting the cover plate 7.

[0048] In some implementations, the second mounting member 71 may be pre-buried on the surface of the second steel bar truss floor deck 2 facing the pipe trench 4 (eg, Figure 1 In this way, the second mounting member 71 is arranged in a pre-embedded manner to reduce the difficulty of setting the second mounting member 71, and the cover plate 7 can be directly fixed to the second mounting member 71, thereby reducing the difficulty of setting the cover plate 7.

[0049] In some embodiments, Figure 1 As shown, the second steel bar truss floor deck 2 is provided with a return eave 22 at one end facing the opening 201, and the second mounting member 71 is provided at the return eave 22. For example, the second mounting member 71 can be pre-buried in the return eave 22, thereby providing a mounting platform for the second mounting member 71 by providing the return eave 22, thereby reducing the difficulty of installing the second mounting member 71.

[0050] In some embodiments, Figure 1 As shown, the second steel truss floor deck 2 is connected to the side of the upper wing plate 32 of the I-beam 3 that is away from the lower wing plate 31. Therefore, the upper wing plate 32 of the I-beam 3 can be used to support the second steel truss floor deck 2, and it is convenient to use the bolts 8 to achieve the connection between the upper wing plate 32 and the second steel truss floor deck 2.

[0056] Therefore, the pipe trench 4 can be defined by two adjacent structural beams, the first steel truss floor deck 1 and the second steel truss floor deck 2. In this way, the first steel truss floor deck 1 can be used to replace the bottom plate of the pipe trench 4, thereby eliminating the need to adopt a hanging formwork construction plan, which is beneficial to improving construction efficiency and reducing safety hazards.
