Abstract
Description
Technical Field
[0001] This utility model belongs to the field of construction devices for concrete buildings, and relates to the support structure for the reinforcing steel of concrete columns. Background Technology
[0002] With the adjustment of my country's industrial structure, a number of industries have been transferred from the developed coastal areas of the east to the central and western regions. Consequently, the number of industrial plant construction projects in these areas is increasing, becoming key projects for regional infrastructure construction. These projects typically use independent foundations, with the pile cap reinforcement usually consisting of a single-layer steel mesh. However, during construction, problems arise such as difficulty in fixing the short column reinforcement during tying and a tendency to tilt; simultaneously, vibrations during concrete pouring can also cause reinforcement misalignment. To address these issues, ensure the verticality of the short columns, reduce reinforcement misalignment, and improve construction efficiency, this invention designs a standardized support device for positioning the reinforcement of short columns in independent foundations. Utility Model Content
[0003] This utility model proposes a combined device for supporting the reinforcing bars of short columns in independent foundations, which effectively prevents the reinforcing bars from shifting during construction.
[0004] The technical solution of this utility model is as follows: A standardized support device for positioning the reinforcing bars of short columns in independent foundations includes a square hoop, a support component, and a level. The square hoop is composed of four right-angled components connected together. Each right-angled component is formed by welding two angle steels together at a right angle and drilling holes in the angle steels with equal spacing. The four right-angled components are stacked in pairs to form a square frame, and the holes in the stacked parts overlap and are fastened together with bolts. The support component is composed of two round tubes of different sizes connected together. A radial hole is drilled in the thinner round tube, and the radial hole is limited by a screw inserted into it. A perforated iron plate is welded to the right-angled component. A radial threaded hole is drilled in the top of the support component, and the radial threaded hole is fixed to the perforated iron plate with screws. The level consists of a bubble level fixed between parallel fixed plates. A spring is fixed to the outer wall of the fixed plate outside the bubble level. A compression plate is fixed to one end of the spring. A round rod is fixed to the bottom of the plate that fixes the bubble level and the compression plate. The round rod is inserted into the hole of the angle steel.
[0005] Preferably, each angle steel is 500mm long and the holes on the angle steel are spaced 50mm apart.
[0006] Preferably, there are four support components. The two circular tubes constituting the support components are a large tube with an outer diameter of 30 mm and an inner diameter of 26 mm, and a small tube with an outer diameter of 26 mm and an inner diameter of 22 mm. The length of both the large and small tubes is 1500 mm, and the radial hole spacing is 100 mm.
[0007] Furthermore, the bubble level is fixed inside the sleeve, and fixing plates are welded to both ends of the sleeve.
[0008] The beneficial effects of this utility model are as follows: The modular structure allows for adjustment of the square frame size, and the length of the supporting components is also adjustable, accommodating the stability requirements of short column reinforcement of different sizes. This device solves the problem of misalignment of foundation short column reinforcement by adding support and fixing measures, avoiding rework caused by reinforcement misalignment. The use of continuous operation and mobile reusability improves construction efficiency and reduces labor costs. Attached Figure Description

[0014] As shown in the figure, a standardized support device for positioning the reinforcing bars of short columns in independent foundations includes a square hoop 1, a support component 2, and a level 3. The square hoop 1 is composed of four right-angled components connected together. Each right-angled component is formed by welding two angle steels together at a right angle, and holes are drilled in the angle steels with equal spacing. The four right-angled components are stacked in pairs to form a square frame. The holes in the stacked parts overlap and are fastened together with bolts. The length of the overlapping part can be adjusted to enlarge or reduce the area enclosed by the square frame, which can adapt to different short column reinforcing bar sizes and ensure the versatility and stability of the device. The support component 2 consists of... The device consists of two round tubes of different sizes joined together. A radial hole is drilled in the thinner round tube, which is then inserted into the thicker round tube. The radial hole is limited by a screw, which keeps the thinner round tube at a certain height and prevents it from slipping. A perforated iron plate is welded to the right-angle component. A radial threaded hole is drilled in the top of the support component 2, and the radial threaded hole is connected to the perforated iron plate by screws. The level 3 consists of a bubble level fixed between parallel fixed plates. A spring 6 is fixed to the outer wall of the fixed plate outside the bubble level. A pressing plate 4 is fixed to one end of the spring 6. A round rod 5 is fixed to the bottom of the plate that fixes the bubble level and the pressing plate 4. The round rod 5 is inserted into the hole of the angle steel.
[0015] Each angle steel is 500mm long, and the holes on the angle steel are spaced 50mm apart.
[0016] There are four support components 2. The two circular tubes constituting the support component 2 are a thicker tube with an outer diameter of 30 mm and an inner diameter of 26 mm, and a thinner tube with an outer diameter of 26 mm and an inner diameter of 22 mm. The length of both the thicker and thinner tubes is 1500 mm, and the radial hole spacing is 100 mm.
[0017] To further protect the bubble level, it is fixed inside a sleeve, with fixing plates welded to both ends of the sleeve. Foam material is placed inside the sleeve, covering the bubble level and leaving an observation area through the bubble's transparent window.
[0018] In use, four right-angled components are arranged around the upper part of the reinforcing cage to form a rectangular frame. The right-angled components overlap partially with adjacent right-angled components. After aligning the holes in the overlapping parts, bolts and nuts are used to tighten them, forming a square hoop 1. The thinner tube is connected to the perforated iron plate of the right-angled component with screws. The thinner tube is inserted into the thicker tube, with the bottom end of the thicker tube touching the ground. After roughly determining the required support length, a screw is inserted into the radial hole of the thinner tube to limit and determine the length. Holding the level 3, the spring 6 is compressed with both hands and kept compressed. The two round rods 5 are inserted into the two holes on the angle steel. Due to the elasticity of the spring 6, the two ends of the level 3 are subjected to outward support. The round rods 5 interact with the holes on the angle steel (the force vector composition direction is radial force, or the angle between the force and the radial force is an acute angle) and will not come out. Observe the bubble level. If it is not level, adjust the contact point between the bottom end of the thicker tube and the ground. After it is roughly suitable, use an iron rod to block the bottom of the thicker tube to prevent slippage. When it is necessary to move to the next short column steel reinforcement support, unscrew the bolts and disassemble the four right-angle components of the square hoop 1 to move to the next position.
