Abstract
The utility model discloses a prestressed reinforced concrete perforated plate kinking tool, which comprises a round pipe and a tubular handle, wherein the middle part of the handle is welded and fixed on the top end of the round pipe to form a T-shaped kinking body with the round pipe, the inner diameter of the round pipe is more than twice of the diameter of a reinforcing steel bar head, and the outer diameter of the round pipe is smaller than the distance between the perforated plates where the two reinforcing steel bar heads are positioned; a pin shaft is vertically and fixedly arranged on the side wall of the round pipe close to the bottom end in a penetrating mode, the round pipe is divided into two parts by the pin shaft, and the maximum distance between the pin shaft and the inner walls of the round pipes on the two sides of the pin shaft ensures that reinforcing steel bar heads can longitudinally penetrate into the round pipes. The structure is simple, the manufacture is easy, and the twisting efficiency is greatly improved.
Description
Technical Field
The utility model relates to a building tool especially relates to a prestressing force reinforced concrete perforated plate kinks frock.
Background
The prestressed reinforced concrete is to compensate the early crack of the concrete, before the member is used (loaded), a pre-pressure is applied to the concrete in advance, namely, the reinforcing steel bars are tensioned in a tension area of the concrete by a manual force method, and the tension area of the concrete is stressed in advance by utilizing the retraction force of the reinforcing steel bars. The stored prestressing force firstly counteracts the prestressing force in the concrete in the tension area when the member is subjected to a tensile force generated by an external load, and then the concrete is tensioned as the load increases, so that the elongation of the concrete is limited, and cracks are delayed or not caused to appear.
When the prestressed reinforced concrete porous plate is installed, the steel bar heads extending out between the plates must be twisted into twisted knots and welded into a whole so as to enhance the earthquake-resistant performance. Usually, a reinforcing bar wrench is used for clamping a reinforcing bar head on any side to be twisted around the other reinforcing bar head in a rotating mode, the wrench is easy to slip in the twisting process due to the structure of the wrench, and the operation is time-consuming and labor-consuming.
Disclosure of Invention
An object of the utility model is to provide a prestressing force reinforced concrete perforated plate kinks frock.
Realize the utility model discloses the technical scheme of purpose is: a prestressed reinforced concrete perforated plate kinking tool comprises a round pipe and a tubular handle, wherein the middle part of the handle is welded and fixed at the top end of the round pipe to form a T-shaped kinking body with the round pipe, the inner diameter of the round pipe is more than twice of the diameter of a reinforcing steel bar head, and the outer diameter of the round pipe is smaller than the distance between two perforated plates where the reinforcing steel bar heads are located; a pin shaft is vertically and fixedly arranged on the side wall of the round pipe close to the bottom end in a penetrating mode, the round pipe is divided into two parts by the pin shaft, and the maximum distance between the pin shaft and the inner walls of the round pipes on the two sides of the pin shaft ensures that reinforcing steel bar heads can longitudinally penetrate into the round pipes.
Further, the maximum distance between the pin shaft and the pipe walls on the two sides of the pin shaft is 1.5 times of the diameter of the steel bar.
The utility model discloses a handle of kinking body is held to prestressed reinforced concrete perforated plate kinking frock during use, makes in the pipe is detained the reinforcing bar head into the pipe after two reinforcing bar heads are aimed at to the pipe bottom, and two reinforcing bar heads are arranged the round pin axle both ends separately this moment, and the handle is turned round 3-5 to arbitrary direction and is changeed two reinforcing bar heads and to be twisted into the twist form, neither can skid also more laborsavingly. The structure is simple, the manufacture is easy, and the twisting efficiency is greatly improved.

Fig. 1 is a schematic structural view of a prestressed reinforced concrete perforated plate kinking tool and a reinforcing steel bar according to an embodiment of the present invention;
fig. 2 is a schematic bottom view of the round tube according to the embodiment of the present invention.
Detailed Description
The following is a detailed description of the preferred embodiments of the present invention.
As shown in fig. 1 and 2, the prestressed reinforced concrete porous plate kinking tool comprises a round tube 1 and a tubular handle 2, wherein the middle part of the handle 2 is welded and fixed on the top end of the round tube 1 to form a T-shaped kinking body with the round tube 1, the inner diameter D of the round tube 1 is more than twice of the diameter of a reinforcement head 10, and the outer diameter D of the round tube is smaller than the distance between two porous plates 20 where the reinforcement heads are located; a pin shaft 3 is vertically and fixedly arranged on the side wall of the round pipe 1 close to the bottom end in a penetrating manner, the round pipe is divided into two parts by the pin shaft, and the maximum distance A between the pin shaft 3 and the inner walls of the round pipes on the two sides of the pin shaft is 1.5 times of the diameter of the steel bar 10.
Before use, the steel bar heads extending out between the plates are bent to a position almost perpendicular to the horizontal plane by a wrench, a distance slightly larger than the diameter of the pin shaft is reserved between the two steel bar heads, then the handle of the twisting body is held by a hand, the steel bar heads are buckled into the round pipe after the bottom end of the round pipe is aligned with the two steel bar heads, the two steel bar heads are respectively arranged at the two ends of the pin shaft, and the handle is twisted in 3-5 directions to twist the two steel bar heads into a twist shape.
The biggest interval between the pipe wall of round pin axle and its both sides should be greater than the diameter of reinforcing bar at first to guarantee that the reinforcing bar can vertically penetrate intraductally, nevertheless if the biggest interval between the pipe wall of round pin axle and its both sides is too big, then be unfavorable for twisting the reinforcing bar, the influence efficiency of knoing, therefore the biggest interval between the pipe wall of round pin axle and its both sides only need slightly be greater than the diameter of reinforcing bar can, can set for about 1.5 times of reinforcing bar diameter usually.
The above only be the embodiment of the utility model discloses a not consequently restriction the patent scope of the utility model, all utilize the equivalent flow transform that the content of the specification was made, or direct or indirect application is in other relevant technical field, all including on the same reason the utility model discloses a patent protection within range.
