Description

Technical Field

[0001] The utility model belongs to the technical field of building construction, and in particular relates to a pre-embedded steel bar head correction device. Background Art

[0002] PC is the abbreviation of precast concrete, which is called PC component in the field of residential industrialization. The prefabricated building construction method of PC components, such as the patent "A method for constructing prefabricated PC components" with publication number CN111155674A, requires that the embedded steel bar head needs to be inserted into the preset positioning plug of the PC component. The steel bar head needs to be corrected before insertion. The traditional correction method is to use a steel casing to insert the bent steel bar head, and then bend it in the opposite direction for correction. The problem is that, as shown in Figure 6 of the above patent, there are multiple steel bar heads (marked as 4 in the figure) connected to each PC component, and it is time-consuming and laborious to correct them one by one; secondly, it is difficult to detect whether the positions of multiple corrected steel bar heads match the PC component. It can only be verified when the PC component is hoisted. There is a lack of detection means, which affects the construction efficiency and quality. Summary of the invention

[0003] In order to overcome the shortcomings of the background technology, the utility model provides a pre-embedded steel bar head correction device, the purpose of which is to use the template to straighten the steel bar head while the template is also a device for detecting the position of the steel bar, so as to complete the correction and detection work at one time and improve the construction efficiency and quality.

[0005] As a further optimization, the screwing portion includes a hexagonal head preset at the upper end of the rotating shaft.

[0006] As a further optimization, a block portion is provided at the lower end of the hexagonal head; the block portion is provided with a through hole with a horizontal axis.

[0007] As a further optimization, the diameter of the through hole corresponds to the diameter of the steel bar head, so that the square portion can be mounted on one of the steel bar heads.

[0008] As a further optimization, a chamfer is provided at the edge of the socket.

[0009] As a further optimization, a blind hole is provided at the lower end of the rotating shaft so that the external threaded section can be sleeved on a steel bar head.

DETAILED DESCRIPTION

[0018] The following is a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings of the present invention. Obviously, the described embodiments are only a part of the preferred embodiments of the present invention, rather than all the embodiments. It should be understood by those skilled in the art that these implementation methods are only used to explain the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0019] Example 1: Please refer to Figure 1-2 ;

[0020] The utility model provides the following technical solutions: a pre-embedded steel bar head correction device, comprising a template 1 and a rotating shaft 2; the template 1 is provided with a plurality of insertion holes 11 penetrating through the upper and lower end surfaces thereof, each insertion hole 11 corresponds to one of the steel bar heads 3, and a threaded hole 12 is provided in the middle of the template 1; an external thread section 21 is provided at the lower end of the rotating shaft 2 for threaded connection with the threaded hole 12; a screwing portion is provided at the upper end of the rotating shaft 2 for connecting a screwing tool to drive the rotating shaft 2 to rotate.

[0021] When in use, the template 1 is mounted on a group of steel bar heads 3 through the insertion hole 11, and a group of steel bar heads 3 corresponds to a PC component. The external threaded section 21 of the rotating shaft 2 is inserted into the threaded hole 12, and the rotating shaft 2 is driven to rotate by the screwing part. When the lower end of the rotating shaft 2 supports the base 4 of the embedded steel bar head 3, the rotating shaft 2 that is continuously rotated drives the template 1 to move upward, and at the same time, brushes each steel bar head 3 upward to straighten the steel bar head 3 and correct the shape, and can correct slightly skewed steel bar heads 3; at the same time, since the insertion hole 11 of the template 1 corresponds to the position of the steel bar head 3, that is, the insertion hole 11 corresponds to the preset positioning plug position of the PC component, when the template 1 brushes upward, the detection of the position of the steel bar head 3 is completed. That is, when the template 1 can smoothly move upward to complete the brushing, the group of steel bar heads 3 corresponds to the positioning plug position, ensuring that the group of steel bar heads 3 can be inserted into the positioning plug of the PC component.

[0022] An exemplary screwing part includes a hexagonal head 22 preset on the upper end of the rotating shaft 2. The hexagonal head 22 can be connected to a manual wrench, or an electric or pneumatic wrench to drive the rotating shaft 2 to rotate.

[0023] In order to further facilitate the rotation of the rotating shaft 2, a block portion 23 is provided at the lower end of the hexagonal head 22; the block portion 23 is provided with a through hole 24 with a horizontal axis. A crowbar is inserted into the through hole 24, and combined with the hexagonal head 22, force can be applied in multiple directions to drive the rotating shaft 2 to rotate, thereby increasing the driving force and facilitating the correction of the steel bar head 3.

[0024] Another use of the through hole 24 is that the diameter of the through hole 24 corresponds to the diameter of the steel bar head 3, so that the block portion 23 can be mounted on the steel bar head 3. Before the template 1 is mounted on a group of steel bar heads 3, the individual steel bar heads 3 with large skewness can be corrected one by one, that is, the block portion 23 is mounted on a bend of a steel bar head 3, and the reverse bend is performed for preliminary correction, and then the template 1 is mounted on the group of steel bar heads 3 for overall correction.

[0025] In order to facilitate the insertion of the steel bar head 3 into the insertion hole 11, a chamfer is provided at the edge of the insertion hole 11. Preferably, both the upper and lower ends of the insertion hole 11 are chamfered, so that the template 1 can be used without distinguishing the front and back sides, which is convenient for operation.

[0026] In order to adapt to the situation that a group of steel bar heads 3 is an odd number, that is, there is a steel bar head 3 located exactly in the middle of the template 1, and the insertion hole 11 overlaps with the threaded hole 12, and only the threaded hole 12 is retained at the overlap, at this time, the lower end of the rotating shaft 2 is provided with a blind hole 25, which is used for the external thread section 21 to be sleeved on the steel bar head 3. The threaded hole 12 is sleeved on the outside of the steel bar head 3, and the external thread section 21 is still connected to the middle position of the template 1 through the blind hole 25, thereby improving the adaptability of the device. It can be seen that the template 1 can be replaced according to the position and number of the steel bar head 3, and the rotating shaft 2 can be universal.

[0027] The advantages of this embodiment are as follows:

[0028] (1) The device can complete the calibration and detection of a group of steel bar heads 3 at one time with high efficiency.

[0029] (2) The device can be connected to different screwing tools, saving manpower and having a large correction force.

[0030] (3) The device has a simple structure, low cost, is easy to carry, and is suitable for use on construction sites.

[0031] In short, the device can complete the calibration and detection of a group of steel bar heads 3 at one time, with high efficiency, low cost and easy use.

In order to make the description concise, all possible combinations of the technical features in the above-mentioned embodiments are not described.
