Referring to fig. 1 to 4, the present invention provides an adjustable-pitch reinforcing bar installation apparatus, including: the device comprises a split screw rod 1, two screw elements 2 and two top elements 3.
The opposite-pulling screw rod 1 penetrates through the steel bar structure 5. The opposite-pulling screw rods 1 are pulled and connected between the two formworks 4 on the two opposite sides of the steel bar structure 5. A gap B is formed between the rebar structure 5 and the form 4.
The two screw pieces 2 are respectively screwed at two ends of the counter-pulling screw rod 1. The two screw pieces 2 are respectively arranged in the gaps B at two opposite sides of the steel bar structure 5.
Each of the supporting members 3 is rotatably mounted to a screw member 2 about a counter screw 1. The opposite sides of the two supporting pieces 3 are respectively provided with a limiting through groove 30. The reinforcing steel bars on two opposite sides of the reinforcing steel bar structure 5 are respectively embedded in the limiting through grooves 30 of the two supporting pieces 3 so as to prevent the distance between the reinforcing steel bar structure 5 and the two formworks 4 from changing.
Referring to fig. 1, in the construction of the steel bar structure, after the counter pull screw is installed between the two formworks, the position of the screw on the counter pull screw is adjusted by rotating the screw, so that the screw is disposed in the gap. And then the supporting and ejecting piece is rotated around the counter-pulling screw rod, so that the limiting through grooves of the supporting and ejecting piece are aligned to the reinforcing steel bars on two sides of the reinforcing steel bar structure. After the limiting through groove is aligned to the steel bar of the steel bar structure, the screwing piece is rotated, so that the steel bar of the steel bar structure is embedded in the limiting through groove of the supporting and ejecting piece. Because the relative both sides of steel bar structure have respectively to prop up the piece from steel bar structure's relative both sides and carry out the top in order to lock steel bar structure, and then ensure that the clearance is indeformable, then the distance of steel bar structure's both sides to the template remains unchanged, and that limit is behind the concreting, and the thickness of the vertical protective layer of steel bar structure's both sides also can remain unchanged.
According to the spacing-adjustable steel bar installation device, the split screw rods arranged on the template are of the main structure, the screwing pieces and the supporting pieces are arranged on the split screw rods, and the steel bar structure is locked through the supporting pieces on the two opposite sides of the steel bar structure so as to ensure that the thickness of the vertical protective layers on the two sides of the steel bar structure is kept unchanged, and the design requirements are met. The steel bar installation device with the adjustable interval is suitable for reinforced concrete structures with different protective layer thickness requirements, and the distance between the screwing piece and the template can be adjusted so as to be adapted to different protective layer thicknesses.
In this embodiment, the screw member 2 is provided with a threaded through hole. The threaded through hole is screwed with the counter-pulling screw rod 1.
As a preferred embodiment, an annular sliding groove is formed at one end of the screw member 2 facing the reinforcing steel bar structure 5. The supporting member 3 is connected with a rotating member 32. The rotating member 32 is slidably disposed in the annular slide groove.
In this embodiment, the annular sliding groove is circular and is disposed on an end surface of the screw member facing one end of the steel bar structure. The annular sliding groove and the threaded through hole are coaxially arranged.
Referring to fig. 3, in the present embodiment, the rotating member 32 is a sleeve. The size of the sleeve pipe orifice is matched with the size of the annular sliding groove. One end of the sleeve can be embedded in the annular sliding groove in a rotating mode around the axis of the sleeve, and the other end of the sleeve extends to the outside of the annular sliding groove and is connected with the supporting and jacking piece 3.
With continued reference to fig. 2 and 3, the supporting member 3 includes two pressing plates 31 disposed opposite to each other. Two pressing plates 31 are respectively connected to opposite sides of the other end of the sleeve. The pressing plate 31 is provided with a notch 310. The notches 310 of the two pressure plates 31 are communicated to form a limiting through groove 30.
The invention provides a construction method of a steel bar installation device with adjustable spacing, which comprises the following steps:
s1: after the reinforcing steel bar structure 5 is bound, the formworks 4 are respectively installed on two opposite sides of the reinforcing steel bar structure 5, so that a gap B is formed between the reinforcing steel bar structure 5 and the formworks 4.
S2: opposite-pulling screw rods 1 are arranged on formworks 4 on two sides of the steel bar structure 5.
S3: two spiral shell spares 2 are rotated in order to adjust the position of spiral shell spares 2 for spiral shell spares 2 set up in the clearance B of the both sides of steel bar structure 5, and the reinforcing bar of the relative both sides of steel bar structure 5 inlays respectively and locates in the spacing logical groove 30 of two top elements 3 in order to prevent that the distance between steel bar structure 5 and two templates 4 from changing.
