[0002] Precast reinforced concrete floor slabs refer to reinforced concrete floor slabs that are prefabricated outside a component prefabrication plant or construction site and then transported to the construction site for installation.

[0003] Precast reinforced concrete slabs are usually cast in a formwork. Both ends of the precast reinforced concrete slabs are usually provided with protruding ribs, and the length of the protruding ribs extending out of the slab needs to be consistent. The conventional operation method is to manually measure the length of the protruding ribs one by one, and then adjust the length of the protruding ribs to be consistent, which is inefficient and the construction quality cannot be guaranteed. Summary of the invention

[0004] The purpose of the present invention is to provide an adjustable bent and extended rib positioning device, which is convenient for controlling the spacing and extended length of the extended ribs to be consistent and can flexibly adjust the installation height of the extended ribs.

[0005] In order to achieve the above-mentioned purpose, the present invention adopts the following technical scheme: an adjustable bending and extending rib positioning device, including an angle steel and a frame, two frames are symmetrically arranged at both ends of the angle steel, the frames are fixedly installed on the mold platform, the angle steel includes a base plate and a vertical plate, symmetrically arranged connecting seats are provided at both ends of the base plate, the connecting seats are fixedly installed on the base plate, a connecting screw is provided on the top plate of the connecting seat, a spring is sleeved on the connecting screw, the end of the connecting screw passes through the mounting plate at the top of the frame and is fixed by a nut, a plurality of equidistantly arranged bayonet sockets are provided on the vertical plate, the bayonet sockets extend downward from the top of the vertical plate, the bottom of the bayonet sockets extend to the surface of the base plate, the bending and extending ribs are clamped in the bayonet sockets, the extending portion of the bending and extending ribs is placed on the base plate, and the bending portion of the bending and extending ribs is provided on the side of the vertical plate away from the base plate.

[0006] As a further description of the above technical solution:

[0007] The base plate is provided with several clamping mechanisms, and one clamping mechanism position corresponds to one bayonet. The clamping mechanism includes a fixed seat, a clamping plate and a fastener. The fixed seat is fixedly mounted on the base plate, and the clamping plate is rotatably mounted on the fixed seat. An arc-shaped clamping plate is provided at the end of the clamping plate. The fastener passes through the clamping plate and is threadedly connected to the base plate.

[0008] As a further description of the above technical solution:

[0009] A plurality of rubber strips are arranged on the inner side surface of the arc-shaped pressing plate, and the rubber strips are arranged along the length direction of the arc-shaped pressing plate.

[0010] As a further description of the above technical solution:

[0011] Three rubber strips are arranged at equal intervals on the inner side of the arc-shaped pressing plate.

[0012] As a further description of the above technical solution:

[0013] The width of the bayonet is equal to the diameter of the extension.

[0014] As a further description of the above technical solution:

[0015] The distance between two adjacent bayonet openings is greater than the length of the bending portion.

[0016] As a further description of the above technical solution:

[0017] A reinforcing plate is arranged below the top plate, one end of the reinforcing plate is fixedly mounted on the top plate, and the other end opposite thereto is fixedly mounted on the bottom plate.

[0018] As a further description of the above technical solution:

[0019] The reinforcing plate is correspondingly arranged below the connecting screw rod.

[0020] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0021] 1. In the present invention, when preparing a reinforced concrete floor slab, the frame is fixedly installed on the formwork platform, the bent and extended ribs are clamped in the clamping holes of the angle steel, the extended part of the bent and extended ribs are placed on the bottom plate of the angle steel, the bent part of the bent and extended ribs is arranged on the side of the vertical plate away from the bottom plate (and against the vertical plate), and the bent part of the bent and extended ribs is pre-buried in the floor slab. The setting of the clamping holes on the angle steel can limit the spacing and extended length of the bent and extended ribs to be consistent.

[0022] 2. In the present invention, since symmetrically arranged connecting seats are provided at both ends of the angle steel, and the connecting seats are elastically connected to the mounting plate of the frame, the height of the angle steel can be controlled by adjusting the length of the connecting screw extending out of the mounting plate, and then the installation height of the bent protruding rib can be controlled.

[0023] 3. In the present invention, in order to further control the extension length of the bent protruding ribs to be consistent, a clamping mechanism is also provided on the angle steel, which clamps the extension part placed on the bottom plate to adjust the extension length of the bent protruding ribs to be consistent, thereby avoiding the inconsistent extension length of the extension part caused by processing errors, which in turn causes the inconsistent extension length of the bent protruding ribs. In addition, the clamping mechanism clamps the extension part, so that when the bent part of the bent protruding ribs is pre-embedded in the floor slab, the angle can be rotated to adjust the angle and fixed by the clamping mechanism, and the pre-embedding of the bent protruding ribs is more flexible.

The setting of the clamping mouth on the angle steel can limit the spacing and protruding length of the bent protruding ribs to be consistent. Since symmetrically arranged connecting seats are provided at both ends of the angle steel, and the connecting seats are elastically connected to the mounting plate of the frame, the height of the angle steel can be controlled by adjusting the length of the connecting screw extending from the mounting plate, and then the installation height of the bent protruding ribs can be controlled. In order to further control the consistent protruding length of the bent protruding ribs, a clamping mechanism is also provided on the angle steel, which clamps the protruding part placed on the bottom plate and adjusts the protruding length of the bent protruding ribs to be consistent, thereby avoiding the inconsistent protruding length of the protruding part caused by processing errors, and then the inconsistent protruding length of the bent protruding ribs. In addition, the clamping mechanism clamps the protruding portion so that when the bent portion of the bent protruding rib is embedded in the floor slab, the angle can be rotated and fixed by the clamping mechanism, making the embedding of the bent protruding rib more flexible.
