Description

Technical Field

[0001] The present application relates to the technical field of bridge equipment, and in particular to a device for controlling a protective layer of steel bars. Background Art

[0002] With the rapid development of bridge and road construction in my country in recent years, beam bridges have been widely used. When pouring bridge piers, it is necessary to first bundle the steel bars. The steel bars include vertical bars and enclosing bars. Several vertical bars are arranged in an enclosing distribution. The enclosing bars are sleeved on several vertical bars. Subsequently, formwork is installed on the outside of the enclosing bars and concrete is poured. However, during the pouring process, due to the deadweight of the cement mortar, the enclosing bars and vertical bars are easily squeezed, which can cause the structural type of the entire steel frame to change. Utility Model Content

[0003] In order to maintain the structural type of the steel frame, the present application provides a device for controlling the steel bar protective layer.

[0004] The present application provides a device for controlling the steel bar protective layer using the following technical solutions:

[0008] By adopting the above technical solution, the support rod is a telescopic adjustment rod. On the one hand, the length of the support rod can be adjusted during the installation process, thereby facilitating the installation of the support rod on the enclosing steel bars. On the other hand, the support rod is convenient for use with enclosing steel bars of different lengths or widths.

[0009] Optionally, the support rod includes a telescopic tube, a telescopic rod and a clamping nut, a sliding cavity is coaxially arranged in the middle of the telescopic tube, the telescopic rod is slidably connected to the sliding cavity along the axial direction of the telescopic tube, the telescopic tube is located at the cavity mouth of the sliding cavity and is surrounded by a plurality of clamping plates, the outer side surface of the clamping plate is provided with a threaded portion, and several of the threaded portions form a complete external thread, the clamping nut is threadedly sleeved on several clamping plates, and there is a gap between two adjacent clamping plates.

[0010] By adopting the above technical solution, when adjusting the length of the support rod, the telescopic rod is stretched, and after the support rod is adjusted to an appropriate length, the clamping nut is rotated, and then the clamping nut forces several clamping pieces to clamp, thereby limiting the telescopic rod.

[0011] Optionally, an abutment block is provided at one end of the telescopic rod and the telescopic tube that is away from each other, and the abutment block abuts against a side of the enclosing steel bar close to the vertical steel bar.

[0012] By adopting the above technical solution, an abutment block is provided, and the abutment block abuts against the enclosed steel bars, thereby limiting the enclosed steel bars to maintain the structural type of the enclosed steel bars.

The limiting nut is located on the side of the abutment block away from the cushion block, and the limiting nut abuts against the abutment block.

[0014] By adopting the above technical solution, after the support rod is adjusted to an appropriate length, the pad is abutted against the outer side of the enclosed steel bar. At this time, the abutment block is moved so that the abutment block abuts against the enclosed steel bar, and then the abutment block is limited by the limiting nut. The abutment block and the pad limit the enclosed steel bar, so that the two ends of the support rod are fixedly connected to the enclosed steel bar.

[0015] Optionally, a first limiting groove is provided on a side of the abutting block close to the pad block, and a groove wall of the first limiting groove abuts against the enclosed steel bar.

[0016] By adopting the above technical solution, a first limiting groove is provided on the abutment block, and the first limiting groove is clamped on the enclosing steel bar, thereby improving the installation stability of the abutment block.

[0017] Optionally, the spacer block is provided with a second limiting groove, and the second limiting groove can form a circular groove with the first limiting groove, and the diameter of the circular groove is adapted to the diameter of the enclosed steel bar.

[0018] By adopting the above technical solution, the first limiting groove and the second limiting groove are clamped on the enclosed steel bar, thereby further improving the stability of the installation.

[0019] In summary, the present invention has the following beneficial effects:

[0020] 1. The two ends of the support rod are connected to the two sides of the enclosed steel bars to support the enclosed steel bars and reduce the possibility of deformation of the enclosed steel bars during the pouring process to maintain the structural type of the steel frame. The minimum thickness of the steel bar protective layer can be controlled by the pads at both ends;

[0021] 2. After adjusting the support rod to the appropriate length, the pad is in contact with the outer side of the enclosed steel bar.
