DETAILED DESCRIPTION
[0017] The following will be combined with the attached Figure 1-Figure 13 The utility model is described in detail, and the technical solutions in the embodiments of the utility model are clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0018] The utility model provides a device for separating steel bars in the cut-off range of a cast-in-place pile. Figure 1-Figure 13 As shown, it includes a positioning ring 1 installed on the longitudinal main reinforcement, a sleeve 2 inserted into the longitudinal main reinforcement, and a pressure ring fixed by a nut 3. The sleeve 2 is located on the positioning ring 1, and the sleeve 2 is fixed by the positioning ring 1 and the pressure ring. The steel bars and concrete in the over-pouring and breaking range of the pile top are separated to avoid the adhesion between the concrete and the steel bars at the top of the pile, reduce the work intensity for the subsequent breaking of the concrete at the top of the pile, and at the same time help protect the steel bars at the top of the pile.
[0019] In the present application, the pressing ring includes a first pressing ring 4 and a second pressing ring 5 , and the first pressing ring 4 and the second pressing ring 5 are arranged at different heights.
[0020] In this application, if Figure 4-Figure 5 As shown, the first pressure ring 4 has an annular pressure ring body A4-1, and the pressure ring body A4-1 has a plurality of circular holes A4-2 for the steel bars to pass through; Figure 6-Figure 7As shown, the second pressing ring 5 has an annular pressing ring body B5-1, and the pressing ring body B5-1 is provided with a plurality of circular holes B5-2 for the steel bars to pass through; the number of the circular holes A4-2 is greater than the number of the circular holes B5-2.
[0021] The end of the longitudinal main reinforcement 6 is provided with a connecting thread, and the compression ring is fixed with a nut 3 by using the connecting thread.
[0022] The following is an explanation of the specific implementation of this application:
[0023] At the stirrup position on the top of the pile body reinforcement cage, install the positioning ring 1 on the longitudinal main reinforcement (insert the positioning ring into the reinforcement), then insert the sleeve 2 into the reinforcement, install the compression ring, and finally fix the compression ring with the nut 3.
[0024] The sleeve 2 is fixed by the positioning ring 1 and the pressure ring.
[0025] The longitudinal main reinforcement 6 of the pile body utilizes the connection thread mouth to fix the compression ring with a nut. After the over-cast concrete is broken, the compression ring, the sleeve, and the gasket can all be recycled and reused.
[0026] Because the longitudinal main reinforcement of the pile body needs to be separately set up with joints, two compression rings are set at different heights.
[0027] The device of the present invention separates the steel bars and concrete in the over-pouring breaking range of the pile top, avoiding the adhesion between the concrete and the steel bars at the pile top, reducing the work intensity of the subsequent breaking of the concrete at the pile top, and at the same time protecting the steel bars at the pile top. If mechanical cutting technology is used, cutting can be performed at the bottom of the concrete breaking range and steel wedges can be used, and the pile head can be smoothly peeled off from the steel bars.
[0028] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
