[0002] During the construction of the overall concrete floor, the concrete changes over time, the hydration reaction continues to deepen, the plasticity decreases while the compressive strength continues to increase. In this process, the concrete floor slab will be affected by internal and external forces such as hydration thermal stress, temperature and humidity stress, gravity, and friction at the bottom of the slab, causing expansion, contraction, and deformation, and then forming various cracks of varying widths and directions, hollows, misalignment, and other defects.

[0003] In order to solve the above defects, in the prior art, prestressed tendons are usually arranged in the concrete floor slab, and after the concrete strength reaches the design requirements, the prestressed tendons are tensioned to apply prestressed pressure to the concrete. When the area of ​​the concrete floor is large, the floor is usually divided into blocks, and post-cast strips are left between adjacent slabs; after the prestressed tendons of the adjacent slabs are all tensioned, micro-expansive concrete with a higher grade than the original structure is used to construct the post-cast strips.

[0004] However, the above method has the following problems: (1) Before the construction of the post-cast joint, the concrete pouring of the adjacent slabs must be completed and the prestressed tendons must be tensioned. This will result in a longer interval and a longer construction period; (2) During the construction of the post-cast joint, the process of cleaning and roughening the structural surface on both sides of the post-cast joint is complicated and there is a risk of leakage.

DETAILED DESCRIPTION

[0026] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0027] like Figure 1-Figure 6 As shown, the present embodiment discloses a tensioning and anchoring structure for an integral seamless floor, including a tensioning end 1, the tensioning end 1 being connected to one end of an anchor cable 3 in a first plate 2; an anchoring end 4 being connected to one end of an anchor cable 3 in a second plate 5, the second plate 5 being arranged adjacent to the first plate 2, and the anchoring end 4 being arranged correspondingly on a side close to the tensioning end 1; a connector 6 being arranged between the tensioning end 1 and the anchoring end 4, and two ends of the connector 6 being respectively connected to the tensioning end 1 and the anchoring end 4.

[0028] In this embodiment, after the concrete pouring of the first plate 2 is completed and the concrete strength reaches the design requirements, the anchor cable 3 in the first plate 2 is tensioned through the tensioning end 1; after the tensioning of the anchor cable 3 in the first plate 2 is completed, the anchor end 4 is connected to the tensioning end 1 through the connector 6, and the tensioning end 1 is connected to the anchor cable 3 in the second plate 5, and then the concrete of the second plate 5 is poured. The anchor end 4 in the second plate 5 is connected to the tensioning end 1 in the first plate 2 through the connector 6, so that during the pouring of concrete for the second plate 5, the position of the anchor end 4 does not tilt or move.

[0029] By adopting this solution, the connector 6 is set, so that the joint between the first plate 2 and the second plate 5 will not separate and become larger due to the shrinkage displacement of the concrete, thereby restraining the cracking of the concrete; through the setting of the above-mentioned structure, when the present invention is carrying out large-area integral concrete seamless floor construction, it is no longer necessary to leave a post-cast strip between adjacent plates, which can not only shorten the construction period, but also avoid the leakage risks caused by cleaning and roughening the post-cast strip.

[0030] According to a further optimized solution, the anchor cable 3 is movably inserted into the protective cover 7 , and an adhesive body is provided between the protective cover 7 and the anchor cable 3 .

[0031] Specifically, the anchor cable 3 is a steel anchor cable, the protective cover 7 is a PE material, and the adhesive is set to be a thermosetting type, which is a prior art. When the concrete pouring of the first plate 2 and the second plate 5 is completed, as the temperature in the concrete changes, the adhesive can firmly bond the anchor cable 3 and the protective cover 7.

[0032] It should be noted that in the traditional post-tensioning construction, the anchor cable 3 is usually set in the galvanized corrugated pipe channel. After the anchor cable 3 is tensioned, high-strength cement slurry needs to be used for high-pressure grouting into the corrugated pipe channel. Not only does it require more construction procedures, but it also consumes more materials.

[0033] By adopting this solution, after the anchor cable 3 is tensioned, it is no longer necessary to perform high-pressure grouting into the protective sleeve 7, which optimizes the traditional post-tensioning construction process, simplifies the construction process, shortens the construction period, and reduces the construction cost.

[0034] A further optimized solution is that the tensioning end 1 includes a first spiral rib 101 sleeved on the outer periphery of the protective sleeve 7, one end of the first spiral rib 101 is connected to the anchor seat 102, a first anchor plate 103 is fitted in the anchor seat 102, a first anchor ring 104 is detachably connected to the first anchor plate 103, one end of the anchor cable 3 in the first plate 2 passes through the anchor seat 102, the first anchor plate 103, and the first anchor ring 104 in sequence, and the first anchor ring 104 and the anchor cable 3 are clamped and fixed by a first clamp 105.

[0035] In this embodiment, the anchor seat 102 is made of PE material. Figure 4 As shown, nuts 1022 are fixed in the protrusions 1021 on both sides of the top of the anchor seat 102, and the nuts 1022 are used to connect with the connector 6; a connecting plate 1023 is fixed on the outer wall of the left protrusion 1021, and a through hole 1024 is provided on the top of the connecting plate 1023; by inserting one end of the first spiral rib 101 into the through hole 1024, the connection between the first spiral rib 101 and the anchor seat 102 can be achieved.

[0036] like Figure 2 , Figure 3As shown, the first anchor plate 103 is an oblong steel forged anchor plate, and the first anchor ring 104 and the first anchor plate 103 are detachably connected by threads. The first anchor plate 103, the first anchor ring 104 and the first clip 105 are all made of steel; the first clip 105 consists of two halves, which can be inserted between the first anchor ring 104 and the anchor cable 3.

[0037] Further optimization scheme, such as Figure 2 As shown, the anchoring end 4 includes a second anchor plate 401, to which a second anchor ring 402 is detachably connected, one end of the anchor cable 3 in the second plate 5 passes through the second anchor plate 401 and the second anchor ring 402 in sequence, and the second anchor ring 402 and the anchor cable 3 are clamped and fixed by a second clip.

[0038] In this embodiment, the second anchor plate 401, the second anchor ring 402, and the second clamp are respectively the same as the first anchor plate 103, the first anchor ring 104, and the first clamp 105.

[0039] Further optimization scheme, such as Figure 2 As shown, the connector 6 includes a bolt 601, the screw end of the bolt 601 passes through the second anchor plate 401 and the first anchor plate 103 in sequence, and is threadedly connected to the anchor seat 102; a spring 602 is arranged between the second anchor plate 401 and the first anchor plate 103, the spring 602 is sleeved on the screw of the bolt 601, and the two ends of the spring 602 are respectively against the second anchor plate 401 and the first anchor plate 103.

[0040] In this embodiment, two bolts 601 and two springs 602 are respectively provided, and the screw end of the bolt 601 is threadedly connected to the nut 1022 in the anchor seat 102. The second anchor plate 401 is connected and positioned by the provided bolts 601 and springs 602.

[0041] It is worth noting that when the length of the anchor cable 3 in the first plate 2 exceeds 80 meters, the anchor cable 3 is tensioned by two ends, that is, both ends of the anchor cable 3 are provided with tensioning ends 1; when the length of the anchor cable 3 in the first plate 2 does not exceed 80 meters, the anchor cable 3 is tensioned by one direction;

[0042] When one-way tensioning is adopted, a fixed end 8 for fixing the end of the anchor cable 3 is provided on the side of the anchor cable 3 away from the tensioning end 1; Figure 5 , Figure 6As shown, the fixed end 8 includes a second spiral rib 801, which is sleeved on the outer periphery of the protective sleeve 7 on the side away from the tensioning end 1, and the second spiral rib 801 is connected and fixed to the pad 802. An extrusion sleeve 803 is fixed in the mounting hole 8021 in the middle of the pad 802 by welding, and one end of the anchor cable 3 is inserted into the extrusion sleeve 803 and fixedly connected thereto. Specifically, the pad 802 is set to be made of cast steel, and both sides of the pad 802 are provided with tying holes 8022. After the tying wire is inserted into the tying hole 8022, the second spiral rib 801 is tied and fixed; the extrusion sleeve 803 is made of steel.

[0043] It should be noted that the fixed end 8, the anchoring end 4 and the tensioning end 1 are all buried in the concrete of the floor.

[0044] The embodiments described above are only descriptions of the preferred modes of the present invention, and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary technicians in this field should all fall within the protection scope determined by the claims of the present invention.
