Description

Technical Field

[0001] The utility model relates to the technical field of concrete slabs, in particular to a recycled concrete slab. Background Art

[0002] Recycled concrete refers to the new concrete made by crushing, cleaning, grading, mixing abandoned concrete blocks with grading in a certain proportion, partially or completely replacing natural aggregates such as sand and gravel, and then adding cement, water, etc. Floor slabs generally refer to precast slabs, which are the floor slabs used in early 20th century buildings, that is, the modules or plates used in the project. Because the concrete precast parts are produced and processed in the precast yard and directly transported to the construction site for installation, they are called precast slabs.

[0003] For example, the patent with publication number CN204418224U discloses a recycled concrete cover plate, which includes a plate-like body and a reinforcing frame embedded in the plate-like body. The two sides of the reinforcing frame are symmetrically provided with a hook extending from the upper surface of the plate-like body, and a receiving recess is provided on one side of the hook, which can be folded into the upper surface of the plate-like body when the hook is not in use and is flush with the upper surface. The device is convenient for moving the concrete plate by providing a hook, but when the concrete plate is used, the hook will remain in the concrete plate forever, resulting in a waste of the hook, and when two concrete plates are spliced, there may be a certain gap between the two concrete plates, which is more troublesome to handle.

[0004] To this end, the utility model provides a recycled concrete slab. Utility Model Content

[0005] In view of the deficiencies in the prior art, the purpose of the utility model is to provide a recycled concrete slab to solve the problems raised in the above-mentioned background technology.

[0007] Furthermore, the plate body, the upper side plate and the lower side plate are an integral structure.

[0008] Furthermore, a plurality of grooves are provided in the upper side plate, the grooves are connected with the first through grooves, and the grooves correspond to the limiting bolts.

[0009] Furthermore, a first thread groove is provided in the insert rod, and the first thread groove corresponds to the limiting bolt.

[0010] Furthermore, the reinforcement frame includes a plurality of transverse reinforcement ribs and a plurality of vertical reinforcement ribs, and the vertical reinforcement ribs are fixedly connected to the transverse reinforcement ribs.

[0012] Furthermore, screw rods are installed at both ends of the handle, and the screw rods correspond to the second thread grooves.

[0013] Furthermore, the screw rod is rotatably connected to the handle.

[0014] Beneficial effects of the utility model: The utility model is a recycled concrete board, comprising a board body, a reinforcement frame, a handle, an upper side board, and a lower side board.

[0015] A reinforcing frame is installed in the plate body, and a handle is installed on the plate body. The plate body can be moved by the handle, and the handle can be removed and reused. Upper side panels and lower side panels are installed on both sides of the plate body. The gap can be compensated by the upper side panels and the lower side panels, thereby facilitating the filling of the gap. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0022] See also Figures 1 to 4 The utility model provides a technical solution: a recycled concrete board, including a board body 1, a reinforcement frame 2 is fixed in the board body 1, two handles 13 are installed on the board body 1, the handles 13 are threadedly matched with the reinforcement frame 2, an upper side plate 3 and a lower side plate 4 are fixed on both sides of the board body 1, a plurality of first through grooves 5 are opened in the upper side plate 3, a plurality of insertion rods 7 are fixed on the lower side plate 4, the insertion rods 7 correspond to the first through grooves 5, and limiting bolts 10 are installed on the insertion rods 7, and a plurality of second through grooves 15 are opened in the board body 1.

[0023] In this embodiment, the plate body 1 is an integral structure with the upper side plate 3 and the lower side plate 4. A plurality of grooves 6 are provided in the upper side plate 3. The grooves 6 are connected to the first through grooves 5. The grooves 6 correspond to the limiting bolts 10. A first thread groove 8 is provided in the insert rod 7. The first thread groove 8 corresponds to the limiting bolt 10.

[0024] Specifically, when the two plate bodies 1 are assembled, the upper side plate 3 of one plate body 1 is placed on the lower side plate 4 of the other plate body 1, so that the insertion rod 7 is inserted into the first through groove 5, and then the limiting bolt 10 is screwed into the first threaded groove 8, so that the two plate bodies 1 can be fixed, which is convenient for filling the gap.

[0025] The reinforcement frame 2 includes a plurality of transverse reinforcement ribs 11 and a plurality of vertical reinforcement ribs 12. The vertical reinforcement ribs 12 are fixedly connected to the transverse reinforcement ribs 11. Four of the vertical reinforcement ribs 12 are provided with second thread grooves 9. The second thread grooves 9 are threadedly matched with the handle 13. Screws 14 are installed at both ends of the handle 13. The screws 14 correspond to the second thread grooves 9. The screws 14 are rotatably connected to the handle 13.

[0026] Specifically, when the plate body 1 needs to be moved, the handle 13 can be installed on the plate body 1 by screwing the screws 14 at both ends of the handle 13 into the second threaded groove 9, thereby facilitating the movement of the plate body 1. After the plate body 1 is installed, the screw 14 can be rotated to disassemble the handle 13, so that the handle 13 can be reused.
