Description

Technical Field

[0001] The present application relates to the technical field of additional reinforcement, and in particular to an additional reinforcement at a concentrated location. Background Art

[0002] Additional reinforcement refers to adding reinforcement to some parts with plate reinforcement to improve strength. In fact, it is the reinforcement added when the designed bearing capacity of the force-bearing reinforcement is insufficient. It is divided into additional longitudinal and additional transverse reinforcement (hanger reinforcement and stirrup reinforcement). The additional plate reinforcement added to the stirrup reinforcement in the densified area and the cast-in-place slab (double-reinforced slab) is additional reinforcement. Concentrated additional reinforcement is a way to reinforce the stress-bearing area in the concrete component. When the concrete component needs to bear greater loads or pressures in certain specific locations, additional reinforcement and additional reinforcement will be added to these stress-bearing areas to enhance its stress-bearing performance.

[0003] When adding additional reinforcement to the concentrated force point, in order to improve the symmetry of the force and avoid generating a large additional bending moment on one side of the area to be strengthened, it is necessary to ensure the accuracy of the placement of the additional reinforcement. Therefore, when arranging the additional reinforcement, it is necessary to first determine its position and then fix it with wire to avoid displacement during concrete pouring. In addition, the additional reinforcement is generally arranged inside the steel frame, which increases the difficulty of wire tying. In summary, the tying and fixing of the additional reinforcement is not very efficient and is not easy. Therefore, in view of the above problems, a concentrated heavy point additional reinforcement is proposed. Utility Model Content

[0004] In view of the shortcomings of the prior art, the present application provides a concentrated and heavy additional reinforcement, which overcomes the shortcomings of the prior art and aims to solve the problem of low efficiency and high difficulty in binding and fixing the additional reinforcement inside.

[0005] To achieve the above objectives, this application provides the following technical solutions:

[0006] A concentrated heavy-duty additional reinforcement comprises a dense stirrup group sleeved outside the longitudinal reinforcement on both sides of the area to be reinforced and a bent additional reinforcement connected to the dense stirrup group, each dense stirrup group comprises three rectangular stirrups and the two outer rectangular stirrups are fixedly provided with suspension hooks, the bent additional reinforcement comprises a sinking section, the two ends of the sinking section are fixedly connected to the upward bending section, the upper ends of the bending sections are fixedly connected to the horizontal upper tie sections, the ends of the upper tie sections are bent to form end hook sections, the upper tie sections at both ends of the bent additional reinforcement are overlapped on the suspension hooks, and the sinking sections of different bent additional reinforcements are fixedly connected by reinforcement rib connectors.

[0007] By adopting the above technical solution, the two ends of the bent additional ribs can be fixed by the suspension hooks, and then the sinking sections at the bottom of the bent additional ribs can be connected together by the reinforcement rib connectors. At this time, under the combined action of the suspension hooks and the reinforcement rib connectors, the bent additional ribs are difficult to slide or rotate and form a cage structure with better force effect. The above installation and fixing process is simple and quick, which effectively improves the construction efficiency while reducing the construction difficulty.

[0008] As a preferred technical solution of the present application, three bent additional bars are provided on the dense stirrup group, and three suspension hooks are correspondingly fixedly provided on the rectangular stirrups.

[0009] By adopting the above technical solution, a cage structure can be formed by using a plurality of three-bent additional ribs, thereby achieving a better force-bearing effect.

[0010] As a preferred technical solution of the present application, the angle between the sinking section and the upward bending section is one hundred and twenty degrees.

[0011] By adopting the above technical solution, a certain modulus effect can be formed, so that the overall size of the bent additional reinforcement is more standardized, thereby improving the convenience of construction and fixation and the accuracy of positioning.

[0012] As a preferred technical solution of the present application, the size of the hanging groove provided on the suspension hook is consistent with the cross-sectional size of the upper tie section, and the end of the hook body of the suspension hook is provided with a guiding chamfer sloping toward the hanging groove.

[0013] By adopting the above technical solution, the upper tie segment can be guided into the hanging groove through the guiding chamfer when fixing it, thereby improving the efficiency of installation and fixing.

[0014] As a preferred technical solution of the present application, the reinforcing rib connector includes a transversely arranged cross-linking rod, three fixed heads are fixedly arranged at the bottom of the cross-linking rod, and a U-shaped groove with a size consistent with the cross-sectional size of the sinking section is opened at the bottom of the fixed head.

[0015] By adopting the above technical solution, the U-shaped groove on the fixing head can be used to clamp the sinking sections on each bent additional rib respectively, so that the bottoms of each bent additional rib are fixedly connected together, which can improve the fixing efficiency and fixing effect.

[0016] As a preferred technical solution of the present application, the lower end surface of the fixing head is provided with grooves sloping toward the U-shaped groove at both sides of the U-shaped groove, and anti-slip convex patterns are fixedly provided on the inner walls on both sides of the U-shaped groove.

[0017] By adopting the above technical solution, the bevel can play a guiding role, making it easier to insert the sinking section into the U-shaped groove, and the anti-slip convex pattern can increase the friction between the U-shaped groove and the sinking section, making it difficult for the sinking section to rotate relative to the fixing head, thereby improving the fixing effect.

[0018] As a preferred technical solution of the present application, the three rectangular stirrups constituting each group of dense stirrups are spaced equally and are all 50 millimeters apart. In addition, the length of the upper tie segment is greater than or equal to 20 times its diameter.

[0019] By adopting the above technical solution, it is possible to ensure that there are enough or long steel bar structures distributed in and near the area to be reinforced to improve the bearing capacity.

[0020] The beneficial effects of the present application are as follows: when installing the bent additional ribs, the upper tie sections at both ends are located above the suspension hooks, and after the positions are aligned, the upper tie sections are pressed into the suspension hooks to complete the fixation of the two ends of the bent additional ribs, and then the sinking sections at the bottom of the bent additional ribs are connected together through the reinforcement rib connectors. At this time, under the combined action of the suspension hooks and the reinforcement rib connectors, the bent additional ribs are difficult to slide or rotate and form a cage structure with better force effect. The above-mentioned installation and fixing process is simple and quick, which effectively improves the construction efficiency while reducing the construction difficulty.

The ends are bent to form end hook sections 24, and the upper tie sections 23 at both ends of the bent additional reinforcement 2 are overlapped on the suspension hooks 3. After the two groups of rectangular stirrups 11 are tied and fixedly connected with the longitudinal reinforcement of the beam body, the bent additional reinforcement 2 can be placed into the area to be reinforced from the opening of the rectangular stirrups 11 on one side, so that the upper tie sections 23 at both ends of the bent additional reinforcement 2 are located above the suspension hooks 3. After the positions are aligned, the upper tie sections 23 are pressed into the suspension hooks 3 to complete the fixation of the two ends of the bent additional reinforcement 2. The operation is simple and quick.

[0029] In addition, the sinking sections 21 of different bent additional reinforcements 2 are fixedly connected by the reinforcement connector 4. By adopting the above technical scheme, after the two groups of rectangular stirrups 11 are tied and fixedly connected with the longitudinal reinforcement of the beam body, the bent additional reinforcement 2 can be placed into the area to be reinforced from the opening of the rectangular stirrup 11 on one side, so that the upper tie sections 23 at both ends of the bent additional reinforcement 2 are located above the suspension hook 3. After the positions are aligned, the upper tie sections 23 are pressed into the suspension hook 3 to complete the fixation of the two ends of the bent additional reinforcement 2, and then the sinking sections 21 at the bottom of the bent additional reinforcement 2 are connected together by the reinforcement connector 4. At this time, under the combined action of the suspension hook 3 and the reinforcement connector 4, the bent additional reinforcement 2 is difficult to slide or rotate and a cage structure with better force effect is formed. In summary, the above installation and fixing process is simple and quick, which effectively improves the construction efficiency while reducing the construction difficulty.

[0030] Reference Figure 2 The dense stirrup group 1 is provided with three bent additional bars 2, and the rectangular stirrup 11 is correspondingly fixed with three suspension hooks 3. The above technical solution can form a cage structure with a plurality of three bent additional bars 2, thereby achieving a better force-bearing effect.

By adopting the above technical solution, when fixing the upper tie section 23, it can be guided into the hanging groove 31 through the guide chamfer 32, thereby improving the efficiency of installation and fixing.

[0033] Reference Figure 4 The reinforcing rib connecting member 4 includes a transversely arranged transverse connecting rod 41, and three fixing heads 42 are fixedly arranged at the bottom of the transverse connecting rod 41. The bottom of the fixing head 42 is provided with a U-shaped groove 43 with the same size as the cross-sectional size of the sinking section 21, and the U-shaped groove 43 on the fixing head 42 can respectively clamp the sinking sections 21 on each bent additional rib 2, so that the bottoms of each bent additional rib 2 are fixedly connected together, which can improve the fixing efficiency and fixing effect.

[0034] Reference Figure 2 The three rectangular stirrups 11 constituting each group of dense stirrups 1 are equally spaced at intervals of fifty millimeters. In addition, the length of the upper tie section 23 is greater than or equal to twenty times its diameter. By adopting the above technical solution, it is possible to ensure that there are enough or long steel bars distributed in the area to be reinforced and its vicinity to improve the bearing capacity.

[0035] Working principle: After the two sets of rectangular stirrups 11 are tied and fixedly connected with the longitudinal reinforcement of the beam body, the bent additional reinforcement 2 is placed into the area to be reinforced from the opening of the rectangular stirrup 11 on one side, so that the upper tie sections 23 at both ends of the bent additional reinforcement 2 are located above the suspension hook 3. After the positions are aligned, the upper tie sections 23 are pressed into the suspension hook 3 to complete the fixation of the two ends of the bent additional reinforcement 2, which can significantly reduce the difficulty of operation and improve work efficiency.

[0036] Subsequently, the U-shaped groove 43 below the fixed head 42 on the reinforcing rib connector 4 is used to clamp the sinking sections 21 on each bent additional rib 2, so that the bottoms of each bent additional rib 2 are fixedly connected together, and the sinking sections 21 at the bottom of the bent additional rib 2 are connected together.
