Description

Technical Field

[0001] The invention relates to the technical field of building construction, and in particular to a steel bar pad group, a steel bar support unit and a steel bar cage support structure. Background Art

[0002] During the construction of the concrete structure of the sub-division project in the main structure, the control of the thickness of the concrete cover of the longitudinal force-bearing steel bars and stirrups is the quality focus of the hidden acceptance of steel bar installation. The thickness of the concrete cover plays a key role in the bonding and anchoring performance, durability and fire resistance of the structural components.

[0003] In order to ensure the reliability of the concrete protective layer and avoid the exposure and corrosion of the steel bars due to the small thickness of the concrete protective layer or the carbonization of the concrete surface, which will lead to the reduction of its effective cross-section, reduced strength, and damage to the integrity of the component, the thickness of the concrete protective layer of the concrete structure beam and slab is generally controlled by step-type cement pads for protection. That is, after the longitudinal force-bearing steel bars and stirrups of the structural beam and slab components are installed and tied, the step-type cement pads are placed on the longitudinal force-bearing steel bars of the beam and slab from bottom to top through the step clips at both ends. The thickness of the bottom cement pad controls the thickness of the concrete protective layer at the bottom of the structural beam and slab, and the protrusions on both sides of the cement pad control the thickness of the lateral concrete protective layer of the structural beam and slab.

[0004] In the above existing schemes, the thickness of the concrete protective layer of the beam-slab structural components is controlled by using stepped cement pads. However, during the physical construction of the building structure, due to the fact that personnel often move on the longitudinal stress-bearing steel bar surface during the installation and binding of the beam-slab steel bars and the hidden acceptance, the stepped cement pads, as their load-bearing points, are easily squeezed, resulting in surface damage and displacement, and the accuracy of controlling the thickness of the protective layer is poor. At the same time, since the stepped cement pads are independent units, any omission or uneven distribution during their installation will affect the large deviation of the thickness of the concrete protective layer of the beam-slab structural components, and the stepped cement pads have a single specification and size, which makes it difficult to meet the different specifications for the thickness of the concrete protective layer of each component (such as beams and slabs) under various environmental categories.

[0005] Therefore, there is an urgent need for a reinforcement pad, a reinforcement support unit and a reinforcement cage support structure to solve the above problems. Summary of the invention

In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0055] like Figure 1-Figure 6As shown, this embodiment provides a steel bar spacer set, including a first spacer 1, a second spacer 2 and a connector 600. A steel bar groove 11 is provided on the top surface of the first spacer 1, and a first protrusion 12 is provided on the bottom surface. Multiple steel bar grooves 11 and multiple first protrusions 12 are arranged at intervals along the length direction of the first spacer 1 (multiple steel bar grooves 11 are arranged at intervals along the length direction of the first spacer 1, and multiple first protrusions 12 are also arranged at intervals along the length direction of the first spacer 1). Lock buckles 13 are provided at both ends of the first spacer 1, and a first connecting hole 14 is provided on the first spacer 1 that penetrates the first spacer 1 along the height direction of the first spacer 1. A splicing groove 21 for cooperating with the first protrusion 12 is provided on the top surface of the second spacer 2, and a second connecting hole 22 is provided on the second spacer 2 that penetrates the second spacer 2 along the height direction of the second spacer 2. The splicing grooves 21 on the second pad 2 are arranged in one-to-one correspondence with the first protrusions 12 on the first pad 1. When each first protrusion 12 on the first pad 1 is spliced ​​with the corresponding splicing grooves 21 on the second pad 2, the first connecting hole 14 and the second connecting hole 22 are coaxial. The first connecting hole 14 and the second connecting hole 22 are used for the connecting member 600 to pass through. In this embodiment, the connecting member 600 is a tension bolt. The first pad 1 and the second pad 2 are both concrete pads.

[0056] The steel bar pad group provided in this embodiment has a steel bar groove 11 on the first pad 1, and the steel bar groove 11 can play an embedding role for the steel bars supported therein. The first pad 1 is provided with multiple steel bar grooves 11 at intervals along the length direction, which can make the force on the first pad 1 more uniform, and avoid the first pad 1 being damaged and broken due to excessive force concentration. The first pad 1 can be used alone to support the steel bar, or it can be spliced ​​with the second pad 2 as a whole to support the steel bar, so that the thickness of the protective layer of the steel bar can be adjusted to meet the design and specification requirements for the thickness of the concrete protective layer. When the first pad 1 and the second pad 2 are spliced ​​and used, the first protrusion 12 and the splicing groove 21 are spliced ​​and matched, and can be connected through the connecting piece 600, so that the relative position between the first pad 1 and the second pad 2 is stable, and the first pad 1 and the second pad 2 are prevented from being affected by the disturbance during the pouring of concrete and falling off and displacing, resulting in uneven thickness of the concrete protective layer, and avoiding the subsequent protection of the steel bar and the adverse effect on the detection of the thickness of the concrete protective layer. The lock buckle 13 is used to connect the steel bars and play a role of restraint and fixation. Through the cooperation of the lock buckle 13 and the steel bars, multiple steel bar pad groups can be connected to form an independent and stable whole, avoiding the steel bar pad group from falling off and moving under interference, achieving the stability of the thickness of the concrete protective layer, effectively realizing the protection of the steel bars, and ensuring that the concrete protective layer thickness detection meets the standards.

When each first protrusion 12 on the first cushion block 1 is spliced ​​with the corresponding splicing groove 21 on the second cushion block 2, the second protrusion 15 on the first cushion block 1 is spliced ​​with the notch 23 on the second cushion block 2. This further improves the stability of the relative position of the first cushion block 1 and the second cushion block 2 after splicing.

[0059] Alternatively, if Figure 1-Figure 4 As shown, when each first protrusion 12 on the first cushion block 1 is spliced ​​with the corresponding splicing groove 21 on the second cushion block 2, the top surface of the first cushion block 1 is parallel to the bottom surface of the second cushion block 2. In addition, when each first protrusion 12 on the first cushion block 1 is spliced ​​with the corresponding splicing groove 21 on the second cushion block 2, the bottom surface of the first cushion block 1 is in contact with the top surface of the second cushion block 2.

[0060] Alternatively, if Figure 1-Figure 4 As shown, when each first protrusion 12 on the first cushion block 1 is spliced ​​with the corresponding splicing groove 21 on the second cushion block 2, the end face of the first end of the first cushion block 1 in the length direction is coplanar with the end face of the first end of the second cushion block 2 in the length direction, and the end face of the second end of the first cushion block 1 in the length direction is coplanar with the end face of the second end of the second cushion block 2 in the length direction.

The longitudinal reinforcement 2001 is a hot-rolled ribbed steel bar with a diameter of 16 to 28 mm and made of steel. The diameter of the tension bolt is 14 mm and made of steel. First, the table-shaped groove A, the table-shaped mortise and tenon bayonet A, the table-shaped groove B and the table-shaped mortise and tenon bayonet B are matched one by one to form a steel bar pad group, and then the individual units of the steel bar pad group are connected to form an independent and stable whole through the locking buckles 13 at both ends and the plain round steel bars. If the beam height is ≥500 mm and tension bolts are required, the tension bolts can be passed through the second template 1002 and the third template 1003 to strengthen the lateral anchorage of the beam member stirrups 2002 and the steel bar pad group. Finally, according to the designed distribution position of the tension bolts and the spacing of the stirrups 2002 of the beam-slab structural member, the steel bar pad group is installed and embedded in the longitudinal force-bearing steel bars and stirrups 2002 of the beam-slab structural member.

The steel bar groove 11 of the steel bar pad group is aligned with the central axis of the beam and slab stirrups 2002 from the bottom and side of the beam and slab member and embedded, so that the steel bar pad group and the beam and slab member stirrups 2002 are in an integrated state. For tall beams that need to be provided with tension bolts to prevent mold expansion, tension bolts can be used to pass through the first connecting hole 14 and the second connecting hole 22 of the steel bar pad group to strengthen the lateral anchorage of the beam member stirrups 2002 and the steel bar pad group. Finally, the beam and slab concrete is poured to form it, and the template 100 support should be removed only after the strength required by the specification is reached.

[0070] The construction process flow is as follows: installation of beam and slab formwork 100 → rust removal of steel bars → straightening of steel bars → cutting of steel bars → bending of steel bars → installation of steel bar spacer group at the bottom of beam → placement of longitudinal stress-bearing steel bars and bent steel bars at the bottom of beam → welding / mechanical connection of longitudinal stress-bearing steel bars at the bottom of beam → placement of longitudinal stress-bearing steel bars at the top of beam → welding / mechanical connection of longitudinal stress-bearing steel bars at the top of beam → installation and binding of beam stirrups 2002 and frame bars → installation of beam lateral steel bar spacer group → layout of slab main bars and distribution bars → installation of steel bar spacer group at the bottom of slab → placement of longitudinal stress-bearing steel bars and distribution bars at the bottom of slab → installation of horse stool bars → placement of longitudinal stress-bearing steel bars and distribution bars at the top of slab → coordinated installation of embedded parts, water and electricity pipes → pouring of concrete → moist maintenance of beam and slab components → removal of formwork 100 support.

[0071] The steel cage support structure provided in this embodiment firstly forms a steel pad group that meets the corresponding specifications and sizes by mortise and tenoning the platform-shaped groove A and the platform-shaped groove B and the platform-shaped mortise and tenon mouth A in the first pad 1 and the second pad 2, and then connects the individual steel pad groups to form an independent and stable whole through the lock buckle 13 and the plain round steel bar to restrict the mobility between the steel pad groups. The longitudinal force-bearing steel bars and stirrups 2002 of the beam-slab structural member are mutually embedded by the steel bar groove 11 to ensure that the steel pad group does not fall off and move alone under interference, thereby ensuring the stability of the thickness of the concrete protective layer. The second tension bolt can also be passed through the first connecting hole 14 and the second connecting hole 22 to realize the lateral anchoring of the steel pad group in the beam-slab structure and the spacing distribution and positioning of the tension bolts, thereby reducing the uneven thickness of the concrete protective layer caused by the displacement of the steel pad group due to disturbance during the pouring of concrete, effectively realizing the protective role to be played by the subsequent steel bars, and achieving high-precision and high-quality effects in the detection of the thickness of the concrete protective layer.

[0072] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principles of the present invention. These improvements and substitutions should also be regarded as the scope of protection of the present invention.
