In addition, the three-dimensional dimensions of length, width and depth should be included in actual fabrication.
For the purpose of making the objects, technical solutions and advantages of the present utility model more apparent, embodiments of the present utility model will be described in further detail below with reference to the accompanying drawings.
The utility model provides a prefabricated concrete composite floor slab with adjustable height, which can conveniently adjust the height of the composite floor slab after being fixed on a beam through bolts welded on the upper flange of the beam, and has better applicability.
Fig. 1 to 4 are schematic views showing the overall structure of an embodiment of a prefabricated concrete composite floor slab with adjustable height according to the present utility model, referring to fig. 1 to 4, and a main body portion of the prefabricated concrete composite floor slab with adjustable height includes a floor slab assembly 100 and an adjusting assembly 200.
The floor slab assembly 100 includes a concrete slab 110 and a reinforcing bar frame 120 fixed to the concrete slab 110, the reinforcing bar frame 120 and the concrete slab 110 being integrally cast into a single floor slab;
The adjusting assembly 200 is used for adjusting the height of the concrete slab 110, and comprises a concrete beam column 210, a first L-shaped frame 220 fixed on the top surface of the concrete beam column 210, a mounting groove 220a formed on the first L-shaped frame 220, a guide rod 230 uniformly fixed on the inner wall of the mounting groove 220a, a threaded rod 240 rotatably mounted on the inner wall of the mounting groove 220a, and a supporting plate 250 sleeved on the guide rod 230 and synchronously meshed with the threaded rod 240, wherein the supporting plate 250 is fixed with the concrete slab 110, and when the threaded rod 240 is rotated, the supporting plate 250 is driven to move up and down along the threaded rod 240, so that the height of the supporting plate 250 is adjusted.
Further, threaded holes 110a are uniformly formed in the bottom end of the concrete slab 110, and through holes 250a matched with the threaded holes 110a are formed in the supporting plate 250; limiting plates 250b are symmetrically fixed on the side walls of the supporting plate 250, and the concrete slab 110 is located between the two limiting plates 250b, so that the concrete slab 110 can be fixed on the supporting plate 250 through bolts, and the concrete slab 110 can be conveniently disassembled and assembled.
Referring to fig. 1 to 4, a prefabricated concrete composite floor slab with adjustable height according to the present embodiment is specifically used as follows: first, the first L-shaped frame 220 is fixed on the concrete beam 210, and then the concrete slab 110 is lifted and fixed on the pallet 250 so that the floor slab can be fixed on the concrete beam 210; when the height of the floor needs to be adjusted, the threaded rod 240 is rotated to drive the supporting plate 250 to adjust the height up and down, so that the floor is synchronously driven to adjust the height, and the height of the composite floor can be conveniently adjusted after the floor is fixed on the concrete beam column 210, so that the applicability is good.
In this embodiment, since the threaded rod 240 has no self-locking structure, the threaded rod 240 may rotate due to external force, so that the height of the concrete slab 110 is erroneously adjusted, for this purpose, referring to fig. 3 again, in this embodiment, the top end of the threaded rod 240 is fixed with an adjusting turntable 240a, and the side wall of the adjusting turntable 240a is uniformly provided with locking holes 240b; the locking assembly 300 further comprises a second L-shaped frame 310 fixed on the first L-shaped frame 220, a plug 320 inserted on the second L-shaped frame 310 and capable of moving relative to the second L-shaped frame 310, a baffle 330 fixed on the plug 320 and a spring 340 sleeved on the plug 320, one end of the spring 340 is fixed on the second L-shaped frame 310, and one screwed end of the spring 340 is fixed on the baffle 330.
When in use, when the adjusting turntable 240a needs to rotate, the plug 320 is pulled, so that the plug 320 is separated from the lock hole 240b, and the adjusting turntable 240a can be rotated at this time; when the adjustment turntable 240a needs to be locked, the latch 320 is released, and the latch 320 is driven to be inserted into a latch hole 240b under the elastic force of the spring 340 reset, so that the adjustment turntable 240a can be locked, and the adjustment turntable 240a can be prevented from being mistakenly touched to change the height of the concrete slab 110.
