[0002] The prefabricated concrete laminated slab often encounters the problems such as the steel mesh sheet floating and warping when the steel mesh is bound and the concrete is poured in the factory production, and further causes the problems such as the truss bar elevation exceeding the limit, the steel bar protective layer of the floor bottom being too large, and the steel bar protective layer of the top being insufficient. These are directly related to the pouring thickness of the floor after assembly, not only affect the floor protective layer, but also develop to the problem of the building structure bearing capacity due to the thickening of the floor for the steel bar protective layer thickness.

[0003] The existing measure for inhibiting the laminated slab steel mesh sheet floating is fixing the end of the steel mesh sheet, but the laminated slab area is large, and only fixing the end of the steel mesh sheet can only inhibit the end of the steel mesh sheet, and the laminated slab web steel mesh sheet also has the problem of floating, so the existing measure of welding the steel segment at the laminated slab side mold can only treat the symptoms and not the root cause, and cannot effectively control the laminated slab steel mesh sheet floating. At present, some laminated slab steel bar protective layer control toolings appear, such as the patent with the announcement number CN216831554U discloses a laminated slab steel bar protective layer control tooling, which comprises a tooling beam, both ends of the tooling beam are movably sleeved with fixed pressing pieces, a plurality of movable pressing pieces are arranged between the two fixed pressing pieces, an opening is formed in the top of each fixed pressing piece and movable pressing piece, a pressing screw is arranged above each fixed pressing piece and movable pressing piece, a positioning nut is fixedly sleeved with the pressing screw in the opening of each fixed pressing piece and movable pressing piece, a triangular notch is formed in the bottom of each fixed pressing piece and movable pressing piece, and an adjusting assembly is fixedly arranged on each fixed pressing piece. The adjusting assembly comprises a magnetic base, two fixed plates and two movable plates, the two fixed plates are fixedly arranged on the front and rear outer walls of the fixed pressing piece, the two movable plates are arranged on one side of the two fixed plates, two strip-shaped holes are symmetrically formed in the side wall of each movable plate, a positioning screw is arranged in each strip-shaped hole, the positioning screw is fixed with the fixed plate, two pressing nuts are arranged on the side of each movable plate away from the fixed plate, the two pressing nuts are threadedly sleeved with the two positioning screws, the magnetic base is arranged below the fixed pressing piece, and the magnetic base is fixed with one end of the two movable plates.

Specific embodiments

[0014] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present utility model.

[0015] The implementation example is as shown in the appendix Figs. 1-2 As shown in the figure: The laminated slab steel bar protection layer adjustment device includes a tooling beam 1. Both ends of the tooling beam 1 are movably sleeved with fixed pressing pieces 2. A plurality of movable pressing pieces 3 are arranged between the two fixed pressing pieces 2. An opening is provided at the top of each of the fixed pressing pieces 2 and the movable pressing pieces 3. A pressing screw 4 is provided above each of the fixed pressing pieces 2 and the movable pressing pieces 3. A positioning nut 5 that is fixedly threadedly sleeved with the pressing screw 4 is provided in the openings of the fixed pressing pieces 2 and the movable pressing pieces 3. A triangular notch 6 is provided at the bottom of each of the movable pressing pieces 3. An adjustment component 7 is provided on each of the two fixed pressing pieces 2. The fixed pressing piece 2 is slidably matched with the adjustment component 7.

[0016] The adjustment component 7 includes a magnetic base 71, a fixing plate 72, a top plate 73 and an adjustment screw 74. Two fixing plates 72 are fixed on the magnetic base 71. Two vertical sliders are provided on the fixed pressing piece 2. Sliding grooves for cooperating with the sliders are provided on the two fixing plates 72. The fixed pressing piece 2 and the fixing plate 72 are slidably connected through the slider sliding grooves. The top plate 73 is installed on the upper end surfaces of the two fixing plates 72. A threaded hole is provided on the top plate 73. The adjustment screw 74 is provided in the threaded hole. A round table is provided at the bottom of the adjustment screw 74. The diameter of the round table is larger than the diameter of the threaded part of the adjustment screw 74. A groove 21 is provided on the fixed pressing piece 2. The cross section of the groove 21 is "convex" and open at the top. The round table at the bottom of the adjustment screw 74 extends into the groove 21. The adjustment screw 74 can rotate freely in the groove 21. An adjustment handle 75 is fixed to the top of the adjustment screw 74 through a pin shaft. When adjusting the height of the fixed pressing piece 2, the adjustment handle 75 is rotated to drive the adjustment screw 74 to rotate, so that the fixed pressing piece 2 slides up and down along the fixing plate 72 to achieve the effect of adjusting the height. The operation is convenient and efficient.

[0017] The fixing plate 72 is also provided with scale lines 721 on its side. The scale lines 721 are distributed from the bottom of the fixing plate 72 upwards. When adjusting the height of the fixing member 2, the position of the bottom end of the fixing member 2 aligned with the scale line 721 can be checked. Adjusting the height of the fixing members 2 on both sides is consistent to ensure that the steel mesh does not tilt. The sliding groove on the fixing plate 72 is a dovetail groove, which keeps the fixing member 2 vertical and prevents it from tilting. The end of the clamping screw 4 away from the positioning nut 5 is fixed with a rotating handle 8, which makes it easy to turn the clamping screw 4.

[0018] The magnetic base 71 contains a cylinder with a strip of permanent or constant-magnetic magnet inside. The outer base is made of a soft magnetic material. When the magnet's N or S poles are aligned vertically (i.e., directly opposite the soft magnetic material base), it is magnetized, exhibiting a strong magnetic field that can attract steel surfaces. When the magnet's poles are horizontal (i.e., directly opposite the soft magnetic material base), it is not magnetized, and there is almost no magnetic force on the base. The adjustment device is fixed to the mold table by activating the magnetic base 71; it is deactivated when removed.

[0019] The specific implementation process is as follows:

[0020] In use, after the steel mesh of the composite slab is tied, a protective pad is added to the bottom of the mesh. After inspection and before the composite slab is poured, the fixture beam 1 is arranged perpendicularly to the truss reinforcement and fixed on the formwork by the magnetic base 71. Then, the triangular notches 6 on the multiple movable pressure members 3 set on the fixture beam 1 are engaged with the truss reinforcement. The rotation of the clamping screw 4 is turned so that the clamping screw 4 moves downward and abuts against the fixture beam 1, thereby limiting the position of the movable pressure member 3. The position of the fixed pressure member 2 on the fixture beam 1 is limited in the same way. Then, the vertical height of the fixed pressure member 2 is adjusted by the adjusting screw 74 of the adjusting component 7. The height of the fixture beam 1 and the movable pressure member changes with the height of the fixed pressure member 2, so as to apply vertical downward pressure to the steel mesh and ensure that the steel mesh as a whole does not float up. During the height adjustment of the fixing member 2, the height of the fixing members 2 on both sides can be checked through the scale line 721 on the fixing plate 72 to ensure that they are consistent. This ensures that the steel mesh will not tilt significantly, thereby guaranteeing the quality of the composite slab.
