Description

Technical Field

[0001] This utility model relates to the field of prefabricated building technology, specifically to a prefabricated floor slab connection structure based on small-diameter soft cable rings. Background Technology

[0002] The traditional construction industry faces outdated production methods that cannot adapt to the current trend of "green" development. Prefabricated buildings meet the major needs of my country's new type of building industrialization. Prefabricated wall panels, prefabricated floor slabs, and prefabricated stair slabs are the easiest prefabricated components to assemble. Traditional prefabricated floor slabs generally use prefabricated composite slabs, and the joints are generally connected by protruding or additional steel bars.

[0003] However, this connection method has many shortcomings in practical applications. For one-way slab joint connections, the calculated thickness of the floor slab at the joint is only the cast-in-place layer, the additional reinforcement at the joint is relatively large, and cracks are prone to appear at the joint. For two-way slab joint connections, reinforcement is exposed on all four sides of the floor slab, making fabrication and transportation difficult. The required length of the reserved reinforcement and the joint width are relatively high, resulting in many construction procedures and low construction efficiency. Therefore, a structure is needed to solve the above problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a precast floor slab connection structure based on small-diameter soft cable rings, which solves the problems of difficult transportation caused by exposed reinforcement around the floor slab and low construction efficiency at the joints.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a precast floor slab connection structure based on a small-diameter soft cable ring, comprising a precast floor slab and a cable ring, wherein the cable ring is embedded in the opposite side of the precast floor slab, and the cable ring includes an embedded part located in the precast floor slab and an exposed part extending from the precast floor slab, wherein the precast floor slabs are spliced ​​together by the cable ring;

[0006] The cable loops of the adjacent precast floor slabs are overlapped in the length direction of the precast floor slabs, and at least two fixed steel bars are inserted between the exposed parts of the cable loops of the adjacent precast floor slabs in the length direction of the precast floor slabs, so as to connect the cable loops of the adjacent precast floor slabs by means of the fixed steel bars.

[0007] Positioning buckles are provided between adjacent fixed reinforcing bars to limit the spacing between the fixed reinforcing bars;

[0008] A gap for pouring concrete is formed between adjacent precast floor slabs.

[0009] Optionally, the cable rings on one side of the precast floor slab include top cable rings and bottom cable rings. The cable rings are arranged in an elongated elliptical ring shape. There are multiple top and bottom cable rings, which are arranged along the length of the precast floor slab.

[0010] Optionally, the top and bottom cable rings are arranged symmetrically in the vertical direction.

[0011] Optionally, the top and bottom cable rings are staggered in the vertical direction.

[0012] Optionally, the precast floor slab is provided with internal reinforcing bars in the direction of its internal elongation to improve the overall strength. The internal reinforcing bars include top reinforcing bars and bottom reinforcing bars.

[0013] Optionally, the precast floor slab connection structure based on small-diameter soft cable rings is characterized in that: the number of top and bottom reinforcing bars of the slab are both multiple, and the top and bottom reinforcing bars are arranged vertically and vertically.

[0014] Optionally, the top slab cable ring is fitted onto the outer surface of the top slab reinforcement, and the bottom slab cable ring is fitted onto the outer surface of the bottom slab reinforcement.

[0015] Optionally, the pre-embedded length and the extended length of the cable ring are symmetrically set.

[0016] This utility model provides a precast floor slab connection structure based on small-diameter soft cable rings, which has the following advantages: By coordinating the precast floor slab and the reinforcing steel bars inside the slab, all the reinforcing steel bars inside the slab are contained within the precast floor slab, so that no reinforcing bars are exposed around the perimeter of the precast floor slab, reducing the difficulty of pouring and making transportation simpler and more convenient. By setting flexible cable rings on both sides of the precast floor slab, when connecting adjacent precast floor slabs, the joints are connected by interlocking rings, and the joint width can be adjusted according to the actual situation to adapt to various different needs, improving the construction error tolerance rate and construction efficiency. The fixed reinforcing steel bars set in the cable rings can improve the firmness of the connection between adjacent locking rings, making the joint connection position more reliable.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0026] Please see Figures 1 to 7 This utility model provides a technical solution: a precast floor slab connection structure based on small-diameter soft cable rings, comprising a precast floor slab 1 and a cable ring, wherein the cable ring is embedded in the opposite side of the precast floor slab 1, and the cable ring includes an embedded part located in the precast floor slab 1 and an exposed part extending from the precast floor slab 1, and the precast floor slabs 1 are spliced ​​together by the cable rings.

[0027] The cable rings of adjacent precast floor slabs 1 are overlapped in the length direction of the precast floor slabs 1. At least two fixed steel bars 4 are installed between the exposed parts of the cable rings of adjacent precast floor slabs 1 along the length direction of the precast floor slabs 1, so as to connect the cable rings of adjacent precast floor slabs 1 by means of the fixed steel bars 4.

[0028] A positioning buckle 7 is provided between adjacent fixed reinforcing bars 4 to limit the spacing between the fixed reinforcing bars 4.

[0029] A gap for pouring concrete is formed between adjacent precast floor slabs 1.

[0030] The cable ring is a flexible cable made of steel strand. During installation, two precast floor slabs 1 are placed side by side. By passing the fixing steel bar 4 through the cable ring, the cable rings on the two precast floor slabs 1 are connected together, thus connecting the two precast floor slabs 1 together. After connection, concrete is poured at the splicing position to fix the two precast floor slabs 1 into a whole. The positioning buckle 7 has through holes on both sides, allowing the fixing steel bar 4 to pass through the through holes. At the same time, the positioning buckle 7 has a threaded sleeve in the middle. By rotating the threaded sleeve, the relative spacing of the through holes on both sides of the positioning buckle 7 can be adjusted to prevent the fixing steel bar 4 from slipping together during pouring. The threaded sleeve is rotatably connected to both ends of the positioning buckle 7 so that the through hole of the positioning buckle 7 can be adjusted to be on the same axis as the fixing steel bar 4.

[0031] In this embodiment, as a preferred option, the cable rings on one side of the precast floor slab 1 include a top cable ring 2 and a bottom cable ring 3. The cable rings are arranged in an elongated elliptical ring shape, and there are multiple top cable rings 2 and bottom cable rings 3, which are arranged along the length direction of the precast floor slab 1.

[0032] The cable rings are arranged in two rows, one above the other, to improve stability during connection. Also, because the cable rings are made of flexible material, the splicing spacing can be adjusted as needed.

[0033] In this embodiment, as a preferred option, the top cable ring 2 and the bottom cable ring 3 are symmetrically arranged in the vertical direction.

[0034] The top cable ring 2 and the bottom cable ring 3 are set one-to-one, which makes installation more convenient. The setting of the upper and lower cable rings can also improve the connection strength.

[0035] In this embodiment, as a preferred option, the top cable ring 2 and the bottom cable ring 3 are staggered in the vertical direction.

[0036] The staggered top cable rings 2 and bottom cable rings 3 can form a zigzag structure, reducing vertical movement of the precast floor slabs 1 on both sides.

[0037] In this embodiment, as a preferred option, the precast floor slab 1 is provided with internal reinforcing bars in the direction of its internal extension to improve the overall strength. The internal reinforcing bars include top reinforcing bars 5 and bottom reinforcing bars 6. There are multiple top reinforcing bars 5 and bottom reinforcing bars 6. The top reinforcing bars 5 and bottom reinforcing bars 6 are arranged vertically and vertically. The top slab clasp 2 is sleeved on the outer surface of the top reinforcing bar 5, and the bottom slab clasp 3 is sleeved on the outer surface of the bottom reinforcing bar 6.

[0038] The internal reinforcement bars can be arranged in a mesh pattern to further improve the strength of the precast floor slab 1 and reduce deformation during construction. The top reinforcement bar 5 cooperates with the top cable ring 2, and the bottom reinforcement bar 6 cooperates with the bottom cable ring 3. The cable rings are sleeved on the internal reinforcement bars, which provides higher strength when connecting adjacent precast floor slabs 1 to prevent the cable rings from accidentally coming out of the precast floor slab 1. Two internal reinforcement bars and a fixing reinforcement bar 4 are inserted into each cable ring. The internal reinforcement bars prevent the cable rings from coming out of the precast floor slab 1, and the fixing reinforcement bar 4 fixes the adjacent locking rings together.

[0039] In this embodiment, as a preferred option, the pre-embedded length and the extended length of the cable ring are set symmetrically.

[0040] The cable ring is partially on the outside and partially inside the precast floor slab 1. The cable ring is fixed to the inner wall of the precast floor slab 1, which improves the fixing strength and ensures the stability of the connection position.

[0041] In this invention, the working steps of the device are as follows:

[0042] 1. After hoisting the two floor slabs together, divide the four fixed steel bars 4 into two groups, pass them through the top locking ring and the bottom locking ring respectively, connect the floor slabs on both sides together, adjust the length of the positioning buckle 7, and put the positioning buckle 7 on both ends of the fixed steel bar 4 to fix the fixed steel bar 4.

[0043] 2. After connecting them together, pour concrete at the connection point. After the concrete has solidified, the adjacent precast floor slabs 1 can be fixed together.

[0044] The specific embodiments provided by this utility model have been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of this utility model. The description of the above embodiments is only for the purpose of helping to understand the method and core ideas of this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of this utility model. Therefore, the content of this specification should not be construed as a limitation of this utility model.
