Description

Technical Field

[0001] The utility model relates to the field of building construction, and particularly relates to a construction structure for a precast joint of a floor bin division joint for floor bin division. Background Art

[0002] At present, for large workshop floors, in order to prevent cracks from appearing during later use, multiple expansion joints (or expansion joints, bin division joints) are designed on the floor. The most traditional floor construction is mainly integral concrete pouring. After pouring, cutting is carried out to divide the whole floor into multiple floor blocks, and a bin division joint is formed between each floor block. Since this bin division joint is formed by cutting later, the strength of the floor block at the bin division joint is very low, and the edge of the floor block is easy to be damaged.

[0003] To overcome the problem of low strength of the floor block at the bin division joint, the skip bin pouring method is currently adopted, that is, each floor block is poured separately one by one. When pouring each floor block, a wire mesh is surrounded around the floor block, and concrete is poured within the area surrounded by the wire mesh (see the prior patent CN 114135077A - Invention Title: A Floor Construction Method with a Concrete Superstructure Reset Cutting and Bin Division Strip-Free Structure). Although this method solves the problem of the edge strength of the floor block to a certain extent, with the increase of the service life, the wire mesh will still be peeled off from the floor block, and finally the edge of the floor block will still be damaged after being rolled.

[0004] Therefore, in summary, there is a problem that the edge of the floor block is easy to be damaged in the pouring of large-area floors at present. Content of the Utility Model

[0005] The technical problem to be solved by the utility model is: to overcome the deficiencies of the prior art, provide a construction structure for a precast joint of a floor bin division joint for floor bin division, and solve the problem that the edge of the floor block is easy to be damaged in the pouring of large-area floors at present.

[0035] Now, the present utility model will be further described with reference to the accompanying drawings. These drawings are all simplified schematic diagrams, which only illustrate the basic structure of the present utility model in a schematic way, so they only show the components related to the present utility model.

[0036] As Figures 1 to 4 shown, a construction structure for precast joints 6 in floor bin division includes a pair of bin division templates 2, which are distributed left and right, and a bin division joint 6 is formed between the two bin division templates 2;

[0037] A pair of precast support components 3 are respectively located in the left and right floor pouring areas. The lower end of the precast support component 3 is fixedly connected to the base layer 1, and the bin division template 2 is fixedly connected to the precast support component 3 so that the bin division template 2 is arranged vertically;

[0038] Multiple steel reinforcement cages 5 are distributed in the left and right floor pouring areas. The lower end of the steel reinforcement cage 5 is fixedly connected to the base layer 1, and the side end of the steel reinforcement cage 5 is fixedly connected to the precast support component 3;

[0039] The load transfer bar 41 has its right end extending into the pouring block of the right-side floor slab and is adapted to be fixedly connected to the floor slab block 7 poured on the right side. Its left end passes through the two bulkhead forms 2 and extends into the pouring block of the left-side floor slab. A sleeve 42 is provided in the pouring block of the left-side floor slab, and the sleeve 42 is fixed in the floor slab block 7 poured on the left side. The left end of the load transfer bar 41 is inserted into the sleeve 42.

[0040] The caulking member 61 is arranged in the bulkhead joint 6 to fill the bulkhead joint 6.

[0041] Specifically, as an alternative implementation manner in this embodiment, as Figure 1 shown, the precast support assembly 3 includes

[0042] The embedded support rod 31 has its lower end inserted into the base layer 1 and is vertically arranged on the base layer 1.

[0043] At least one connecting rod 32, one end of which is welded to the bulkhead form 2 and the other end of which is welded to the embedded support rod 31.

[0044] The connecting plate 33, one end of which is welded to the bulkhead form 2 and the other end of which is penetrated by the embedded support rod 31. A locking nut 34 is connected to the embedded support rod 31, and the locking nut 34 locks the connecting plate 33 downward.

[0045] The number of the connecting rods 32 is determined according to the height of the bulkhead form 2. If the bulkhead form 2 is relatively high, two connecting rods 32 and one connecting plate 33 need to be configured.

[0046] Both the connecting rod 32 and the connecting plate 33 are welded to the bulkhead form 2.

[0047] By fixedly connecting the embedded support rod 31 to the base layer 1, the bulkhead form 2 can be vertically placed on the base layer 1 through the connecting plate 33 and the connecting rod 32, so as to form a stable bulkhead joint 6 between the left and right bulkhead forms 2.

[0048] Specifically, as an alternative implementation manner in this embodiment, as Figures 1 to 4 shown, the bulkhead form 2 is made of flat steel, and a rod hole 21 for the load transfer bar 41 to pass through is formed in the flat steel.

[0049] Each bulkhead form 2 includes at least one flat steel, and each flat steel includes at least one connecting rod 32 connected to the embedded support rod 31.

[0050] In this embodiment, each bulkhead form 2 includes two flat steels. The upper flat steel includes one connecting rod 32 and one connecting plate 33, and the lower flat steel includes one connecting rod 32 and one rod hole 21.

[0051] Specifically, as an alternative implementation manner in this embodiment, as Figure 4As shown, the caulking member 61 includes a foam strip and caulking glue; the caulking glue is located above the foam strip.

[0052] The foam strip and caulking glue are installed after the casting is completed and the partition joint 6 is cleaned by blowing air.

[0053] Specifically, as an alternative implementation in this embodiment, as Figure 3 Figure 4 As shown, the steel reinforcement cage 5 includes multiple horizontal steel bars and vertical steel bars. The horizontal steel bars and vertical steel bars are tied with steel wires to form a rectangular three-dimensional structure framework. Among them, the lower ends of the vertical steel bars are inserted into the base layer 1.

[0054] The steel reinforcement cage 5 is relatively common in the construction field and will not be elaborated here.

[0055] The construction method of pouring the floor slab using the precast joint partition joint 6 construction structure for the floor slab partition of the present utility model is as follows:

[0056] First, the left and right partition formworks 2 are respectively fixed by the precast support assembly 3, so that a stable partition joint 6 is formed between the left and right partition formworks 2;

[0057] Then the workers tie the steel reinforcement cage 5 within the floor slab pouring area;

[0058] First, pour the floor slab block 7 within the right floor slab pouring area. The right end of the dowel bar 41 is poured into the floor slab block 7. After the right floor slab block 7 solidifies, start pouring the left floor slab block 7. Before pouring the left floor slab block 7, install a sleeve 42 on the dowel bar 41, and then wrap a plastic film on the sleeve 42. The plastic film mainly prevents concrete from entering the sleeve 42, and then pour the left floor slab block 7. After the left floor slab block 7 solidifies, the sleeve 42 is fixed together with the left floor slab block 7. The right floor slab block 7 can achieve relative movement relative to the left floor slab block 7 through the axial movement between the dowel bar 41 and the sleeve 42. The dowel bar 41 cannot make radial movement within the sleeve 42, thereby restricting the movement of the left floor slab block 7 relative to the right floor slab block 7 in the radial direction of the dowel bar 41. That is, adjacent floor slab blocks 7 can only move in the left-right width direction of the partition joint 6 by relying on the dowel bar 41, and cannot move in the front-back direction, ensuring the structural stability between adjacent floor slab blocks 7 in the entire large-area floor slab.

[0059] Since flat steel is provided at the edge of each floor slab block 7, and the partition joint 6 is formed with adjacent flat steel through the flat steel, the structural stability of the partition joint 6 is ensured; secondly, the flat steel is fixed to the edge of the floor slab block 7 by the precast support assembly 3, so that the flat steel can be more stably arranged at the floor edge, avoiding the flat steel peeling off from the edge of the floor slab block 7, improving the adhesion of the flat steel on the floor slab block, and ensuring the structural stability of the entire floor slab block 7.

[0060] Inspired by the above ideal embodiments of the present utility model, through the above description, relevant staff can completely make various changes and modifications without departing from the technical idea of this utility model. The technical scope of this utility model is not limited to the content in the specification, and its technical scope must be determined according to the scope of the claims.
