Description

Technical Field

[0001] The utility model belongs to the technical field of construction, and in particular relates to an assembled floor structure. Background Art

[0002] Steel structure floors are prefabricated in factories and then installed at construction sites. Currently, common steel structure floors are usually prepared by combining steel plates with concrete.

[0003] In the prior art, when multiple floor slabs are spliced ​​and installed, the side seams between the slabs are in the form of V-shaped, U-shaped and groove (double-tooth) shapes. Figure 8 This splicing method is simple, and concrete is used for filling after splicing. However, there are no anchors at the splicing points, which results in insufficient strength at the splicing points, and the splicing points are prone to cracking and are not stable and reliable enough.

[0004] In addition, this splicing method cannot fine-tune the spacing between adjacent floor slabs according to actual conditions, and sometimes causes gaps between the edge of the floor slab and the edge of the frame after splicing. When the gap is within 120mm, only concrete needs to be poured, but when the gap is too large, workers need to install steel bars and cement to repair the gap. Jiangsu Feifan Heavy Industry Co., Ltd. has disclosed an assembled steel structure floor with application number 202223446256.4. Although this solution is more stable than V-shaped, U-shaped and groove (double-tooth) shaped assembly methods, how to adjust the assembly spacing between floor slabs according to actual conditions is still a technical problem that needs to be solved. Utility Model Content

[0005] The utility model aims to solve the technical problems existing in the assembly of the assembled floor structure in the prior art and provides an assembled floor structure.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A prefabricated floor structure includes a floor body, wherein the top and bottom surfaces of one side of the floor body are provided with a plurality of installation grooves at intervals, a connecting rod is rotatably installed in the installation groove, and a positioning shaft is provided at one end of the connecting rod away from the installation groove, and the top and bottom surfaces of the other side of the floor body are provided with a plurality of connecting grooves compatible with the connecting rod, and each connecting groove is provided with a plurality of positioning grooves compatible with the positioning shaft at intervals, a groove is provided in the middle of the side end of the floor body close to the positioning groove, an extrusion plate is movably provided in the groove, an extrusion spring is installed between the extrusion plate and the groove wall of the groove, and a clamping plate compatible with the groove is prefabricated in the middle of the side end of the floor body close to the connecting rod, and when the positioning shaft is clamped in any positioning groove, the extrusion spring is in a compressed state.

[0008] Furthermore, both sides of each installation groove are provided with limiting grooves, and a rotating shaft is rotatably installed at one end of the connecting rod away from the positioning shaft, and the rotating shaft is installed in the limiting groove.

[0009] Furthermore, a plurality of guide grooves are provided on the extrusion plate, and guide rods matched with the guide grooves are provided on the clamping plate.

[0010] Furthermore, the cross section of each positioning groove is an L-shaped groove.

[0011] Furthermore, a reinforcing strip is provided on the floor slab body, and the reinforcing strip is connected to the floor slab body by positioning bolts.

[0012] Furthermore, the opening of the guide groove is an expansion opening.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] The splicing method of the utility model is stable and reliable. When splicing two adjacent floor slabs, the clamping plate of one floor slab body is clamped into the groove of the other floor slab body, and the positioning axis of the connecting rod on one floor slab body is clamped into the positioning groove on the other floor slab body. Under the action of the extrusion spring and the extrusion plate, the distance that the clamping plate extends into the groove can be adjusted, and the positioning axis is clamped with different positioning grooves at the same time. After clamping, under the action of the spring force of the extrusion spring, the connecting rod is tightened to ensure that the positioning axis will not move, so that the floor slab bodies are stably connected, and according to actual operations, the distance between adjacent floor slab bodies can be fine-tuned, and the distance between the floor slab body at the edge and the frame is controlled between 120mm, so that the layout of the floor slab is more reasonable.

[0015] The utility model arranges positioning grooves on both sides of the installation groove to ensure that the connecting rod can rotate in the installation groove, and can ensure that the connecting rod can be pressed into the installation groove and the connecting groove during connection.

[0016] When assembling the floor slab, the utility model can pre-connect the guide groove on the extrusion plate with the guide rod on the clamping plate, and set the end of the guide groove to expand outward, so as to facilitate the alignment and clamping of the two and facilitate subsequent assembly and connection.

[0017] The cross section of the positioning groove of the utility model is set to be an L-shaped groove. When the positioning shaft on the connecting rod is inserted into the positioning groove, one of the floor boards is finely adjusted outward so that the positioning shaft is inserted into the lower part of the L-shaped groove. In addition, the spring force of the extrusion spring increases the connection stability. BRIEF DESCRIPTION OF THE DRAWINGS
