Detailed Description
The present utility model will be described in further detail with reference to the drawings and examples, in order to make the objects, technical solutions and advantages of the present utility model more apparent. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the utility model.
Referring to fig. 1-2, an embodiment of the present utility model provides a post-cast construction structure for a floor slab, which includes a beam structure 1, pipe members 2, and reinforcing steel bars 3. The number of the pipe fittings 2 is a plurality of pipe fittings 2 are distributed at intervals along the length direction of the beam structure 1 (the whole number of the pipe fittings 2 distributed on the beam structure 1 is not completely drawn in the figure), the central line of the pipe fittings 2 is perpendicular to the length direction of the beam structure 1 and buried in the beam structure 1, at least one end of each pipe fitting 2 extends to the surface of the beam structure 1, namely, the pipe fittings 2 can penetrate the beam structure 1 on one side or penetrate the beam structure 1 on two sides, specifically, when the beam structure 1 is positioned around the building structure, the pipe fittings 2 penetrate the beam structure 1 on one side, when the beam structure 1 is positioned in the middle of the building structure, the pipe fittings 2 penetrate the beam structure 1 on two sides, and the reinforcing steel bars 3 penetrate the pipe fittings 2 after the beam structure 1 is finished and before pouring of the floor slab 10.
The beam structure 1 is provided with the installation space for the steel bars 3 by adopting the mode of embedding the pipe fittings 2, after beam pouring is completed, channels through which the steel bars 3 can penetrate are formed in the pipe fittings 2, and before floor 10 pouring is carried out, the steel bars 3 are respectively penetrated with a plurality of pipe fittings 2 so that the floor 10 can be subjected to pouring construction operation.
According to the floor post-pouring construction structure provided by the embodiment of the utility model, before the beam structure 1 is poured, the steel bars 3 are not needed to be embedded, so that potential safety hazards caused by the fact that the steel bars 3 are exposed outside are avoided, or the steel bars 3 are bent by avoiding the installation of a beam template before the beam structure 1 is constructed, or before the floor 10 is poured, the concrete layer of the beam structure 1 is not damaged by the implantation of the steel bars 3, so that the quality is unreliable, the operation is simple, and the safety and the reliability are realized.
Further, the distance between two adjacent pipe fittings 2 is 200mm. So can reasonable lay pipe fitting 2 quantity, both avoided pipe fitting 2 quantity too much to lead to producing the extravagant cost of material and increased, still avoided pipe fitting 2 quantity too little to lead to floor 10 to pour the poor problem of back intensity.
Further, the minimum diameter of the pipe fitting 2 for the steel bar 3 to penetrate is at least 2mm larger than the diameter of the steel bar 3. So, can smoothly pass through when guaranteeing that reinforcing bar 3 wears to establish pipe fitting 2 to improve installation effectiveness. The minimum diameter of penetration refers to the minimum diameter that needs to be met when the inside of the pipe fitting 2 is not a regular smooth plane, so as to ensure that the steel bar 3 can penetrate the pipe fitting 2.
Further, when only one end of the pipe fitting 2 extends to the surface of the beam structure 1, the inner wall of the pipe fitting 2 and the steel bars 3 are prefilled by the bar planting glue. Therefore, when the pipe fitting 2 penetrates through the beam structure 1 on one side, the inside of the gap of the pipe fitting 2 is prefilled by the planted bar glue, so that reliable connection between the steel bar 3 and the pipe fitting 2 is ensured, and the steel bar 3 is prevented from falling off from the pipe fitting 2.
When needing to be described, when the pipe fitting 2 penetrates the beam structure 1 from two sides, the beam structure 1 is positioned in the middle of the building structure, when the steel bar 3 penetrates the pipe fitting 2, two ends of the steel bar 3 also need to penetrate the single-side penetrating pipe fitting 2 positioned on the beam structure 1 around the building structure, so that the gap in the pipe fitting 2 of the beam structure 1 from two sides does not need to be pre-buried and fixed by the bar planting glue, and the construction efficiency is improved.
Further, the inner wall surface of the pipe member 2 has a height difference in the length direction thereof. The height difference refers to that the inside of the pipe fitting 2 is not in a regular smooth plane structure, but the inner wall is arranged in an irregular structure, so that when the gap of the pipe fitting 2 is embedded by the bar planting glue, the filling area of the bar planting glue can be increased, and an irregular shape can be generated after the bar planting glue is solidified, thereby improving the connection stability of the steel bar 3 and the pipe fitting 2.
In particular, the tube 2 may be a bellows. Therefore, after the bar planting glue is filled, the connection stability of the steel bar 3 and the pipe fitting 2 can be improved.
Furthermore, the diameter of the middle part of the tube 2 can be larger than the diameters of the two ends of the tube 2. In addition, a plurality of protrusions and/or a plurality of depressions may be provided on the inner wall of the pipe 2 along the length direction thereof. Therefore, by adopting the scheme, the connection stability of the steel bar 3 and the pipe fitting 2 can be improved after the reinforced plastic glue is filled.
The foregoing description of the preferred embodiments of the utility model is not intended to be limiting, but rather is intended to cover all modifications, equivalents, and alternatives falling within the spirit and principles of the utility model.
