Description

Technical Field

[0001] This application relates to the field of wall reinforcement positioning technology, and in particular to wall reinforcement positioning and protective layer control fixtures. Background Technology

[0002] In the field of construction engineering, the precise positioning of wall reinforcement and the control of concrete cover thickness are directly related to structural safety and durability. Traditionally, precast support rods are commonly used as positioning tools for reinforcement spacing and cover thickness. However, this method has significant drawbacks: insufficient stability; during concrete vibration, the support rods are prone to displacement or toppling due to vibration and impact, leading to deviations in reinforcement spacing and uncontrolled cover thickness. Uneven cover thickness can cause quality problems such as reinforcement corrosion and concrete cracking, affecting the structural lifespan. Furthermore, construction efficiency is low; frequent manual adjustments are required after displacement, increasing rework and delaying the construction period.

[0003] While existing technologies attempt to use metal positioning clamps, most structures are fixed and cannot flexibly adapt to different rebar spacing requirements, and lack reliable anti-loosening mechanisms.

[0004] Therefore, there is an urgent need for a tooling that combines adjustability, vibration resistance, and installation stability to solve the failure problem of traditional processes under vibration conditions and ensure construction accuracy and efficiency. Utility Model Content

[0005] To address or partially address the problems existing in related technologies, this application provides a tooling for positioning and controlling the protective layer of wall reinforcement bars, aiming to solve the problem of stable installation of wall reinforcement bars.

[0006] This application provides a tooling for positioning wall reinforcement and controlling the protective layer, including:

[0007] Positioning rod, locking block, movable ring, movable locking block, slot, fixing pin;

[0008] The locking blocks are installed at both ends of the positioning rod. The locking blocks at both ends are divided into the wall reinforcement positioning part and the protective layer positioning part. The positioning rods on both sides of the locking blocks are the protective layer positioning part.

[0009] A movable ring is installed on the positioning rod inside the card block, and a movable card block is installed on the outer ring of the movable ring. A slot is opened on the inner ring of the movable ring, and a fixing pin is provided in the slot. The fixing pin is inserted into the slot to fix the movable ring on the positioning rod.

[0010] Optionally, in some embodiments, the positioning rod is divided into two sections. One section is equipped with a telescopic sleeve, and the other section of the positioning rod is installed inside the telescopic sleeve. A positioning bolt that penetrates to the inside is installed on the telescopic sleeve, and the other section of the positioning rod is fixed inside the telescopic sleeve by rotating the positioning bolt.

[0011] Optionally, in some embodiments, the two ends of the positioning rod are coated with anti-rust paint.

[0012] The technical solution provided in this application may include the following beneficial effects:

[0013] The mechanical locking structure of the movable ring and fixed pin rigidly fixes the locking block and movable locking block to the positioning rod, forming a two-way clamping of the reinforcing bar. During concrete vibration, this effectively resists vibration impact, solves the defect of easy displacement of the support rod, and ensures zero deviation in the spacing of the reinforcing bars and the thickness of the protective layer. The use of the telescopic sleeve and the positioning bolt together allows for adjustment of the length of the positioning rod, quickly adapting to different wall thickness requirements, improving construction efficiency and reducing spare parts costs.

[0023] The precise positioning of wall reinforcement and the control of concrete cover thickness are directly related to structural safety and durability. Traditional construction commonly uses precast support rods as positioning tools for reinforcement spacing and cover thickness. However, this method has significant drawbacks: insufficient stability; during concrete vibration, the support rods are easily displaced or toppled due to vibration and impact, leading to deviations in reinforcement spacing and uncontrolled cover thickness. Uneven cover thickness can cause quality problems such as reinforcement corrosion and concrete cracking, affecting the structural lifespan. Furthermore, construction efficiency is low; frequent manual adjustments are required after displacement, increasing rework and delaying the construction period. While existing technologies attempt to use metal positioning clamps, most structures are fixed, unable to flexibly adapt to different reinforcement spacing requirements, and lack reliable anti-loosening mechanisms.

[0024] To address the aforementioned issues, this application provides a wall reinforcement positioning and protective layer control fixture. Through a mechanical locking structure of a movable ring and a fixed pin, the locking block and movable locking block are rigidly fixed to the positioning rod, forming a bidirectional clamping effect on the reinforcement. During concrete vibration, this effectively resists vibration impact, solves the problem of support rods easily shifting, and ensures zero deviation in reinforcement spacing and protective layer thickness. The combined use of a telescopic sleeve and positioning bolts allows for adjustment of the positioning rod length, quickly adapting to different wall thickness requirements, improving construction efficiency and reducing spare parts costs.

[0025] The technical solutions of the embodiments of this application are described in detail below with reference to the accompanying drawings.

[0026] Figure 1 This is a schematic diagram of the wall reinforcement positioning and protective layer control fixture shown in the embodiments of this application.

[0027] See Figure 1 A tooling for positioning wall reinforcement and controlling the protective layer, comprising:

[0028] Positioning rod 1, locking block 2, movable ring 3, movable locking block 4, telescopic sleeve 5, positioning bolt 6, slot 7, fixing pin 8;

[0029] The positioning rod 1 is divided into two sections. One section is equipped with a telescopic sleeve 5, and the other section of the positioning rod 1 is installed inside the telescopic sleeve 5. By adjusting the position of the positioning rod 1 inside the telescopic sleeve 5, the spacing of the wall reinforcement can be adjusted. A positioning bolt 6 that penetrates to the inside is installed on the telescopic sleeve 5. The positioning rod 1 is fixed inside the telescopic sleeve 5 by rotating the positioning bolt 6.

[0030] The locking blocks 2 are welded to the two positioning rods 1 respectively. The two locking blocks 2 divide the positioning rods 1 into a wall reinforcement positioning section and a protective layer positioning section. The section between the two locking blocks 2 is the wall reinforcement positioning section, and the positioning rods 1 on both sides of the locking blocks 2 are the protective layer positioning sections. A sliding movable ring 3 is installed on the positioning rod 1 inside the locking blocks 2. A movable locking block 4 is welded to the outer ring of the movable ring 3. A slot 7 is opened on the inner ring of the movable ring 3, and a fixing pin 8 is provided in the slot 7. In use, the wall reinforcement on one side is locked into the locking block 2 and movable locking block 4 at one end of the positioning rod 1. Then, the fixing pin 8 is inserted into the slot 7 to fix the movable ring 3 to the positioning rod 1, so that the locking blocks 2 and movable locking blocks 4 clamp the wall reinforcement on one side. The wall reinforcement on the other side is clamped by sliding another movable ring 3 and movable locking block 4, in conjunction with the locking block 2 at the other end.

[0031] The two ends of the positioning rod 1 are coated with anti-rust paint to prevent the positioning rod 1 from rusting.
