[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technical personnel in this field without creative work are within the scope of protection of the utility model.
[0020] See also Figure 1 to Figure 2The utility model provides a technical solution: a special steel mesh for preventing concrete cracking at the pre-buried wire pipe of a thin plate, comprising a template 3, a plurality of fulcrums and protective layer control limbs 2 distributed in an eight-shaped shape are placed in the middle of the upper part of the template 3, a core constraint ring 1 is arranged at the top of the plurality of fulcrums and protective layer control limbs 2, and anti-cracking reinforcement ribs 4 are welded on the left and right sides of the outer walls of the plurality of core constraint rings 1, and an anchor hook 5 is welded on the end of each anti-cracking reinforcement rib 4 away from the core constraint ring 1, and the outer walls of the plurality of core constraint rings 1 are welded along the circumferential direction. There are multiple longitudinal ribs 6, and the inner cavities of several core restraint rings 1 are fixedly plugged with wire pipes 8. The restraint rings can restrain the direction of the wire pipes 8, and can also make the concrete poured around the wire pipes 8 play a better restraining role on the wire pipes 8 as a whole. By changing the diameter, number and spacing of the core restraint rings 1 of the steel mesh, the steel mesh can be used to adopt a radial distribution in the concentrated areas and intersections of multiple wire pipes 8, and they can be arranged closely to ensure that the concrete at the bottom of the wire pipes 8 is poured smoothly and vibrated densely, thereby enhancing the bearing capacity of the floor slab and reducing the possibility of cracking at the pre-buried parts of the wire pipes 8 on the floor slab.
[0021] In this embodiment, the core constraint rings 1 are arranged in pieces, and the two constraint rings located in the middle are half rings. The constraint ring spacing is 80 to 200 mm, and the diameter is 40 to 80 mm. The spacing between each constraint ring is 80 to 200 (mm) to ensure that the special steel mesh covers the concentrated area and the intersection area of the wire tube 8. To ensure the placement of the steel mesh in the intersection area, the two middle rings of the mesh are treated as half rings. To ensure the constraint effect, the constraint ring diameter is set to 40 to 80 (mm).
[0022] In this embodiment, the vertical height of the fulcrum and protective layer control limb 2 is 15 to 40 mm. The height of the core constraint ring 1 is adjusted to ensure that the position of the wire tube 8 is not affected, while also ensuring that the concrete protective layer has sufficient protective thickness. The protective limb is connected to the core constraint ring 1 by welding.
[0023] In this embodiment, the anti-crack reinforcement ribs 4 are arranged in the transverse mid-section of the core restraining ring 1 and intersect with the longitudinal ribs 6 .
[0024] In this embodiment, the wire tube 8 is placed in the core restraint ring 1 and fixed at each intersection.
[0025] In this embodiment, a plurality of distribution bars 7 are arranged below a number of anti-cracking reinforcement bars 4, and a total of four distribution bars 7 are arranged. The length of the distribution bars 7 on both sides does not exceed the last constraint ring, so that the anchor hooks 5 at the four corners of the steel mesh can be anchored to the lower or upper layer of the floor slab through manual intervention, and the intersection of the wire tube 8 can be connected by reducing the size of the upper mesh (reducing the distribution bars 7) and the constraint ring half ring processing.
[0026] In this embodiment, the anchor hook 5 at the end of the anti-crack reinforcement rib 4 is anchored to the distribution rib 7. By setting the length and size of the anchor hook 5 to anchor to the through-length ribs of the lower or upper layer of the floor slab, the overall force is strengthened.
[0027] In this embodiment, the number of longitudinal ribs 6 is four, and a total of four longitudinal ribs 6 are arranged, which are respectively arranged at the intersection of the fulcrum protection limb, the anti-cracking reinforcement rib 4 and the core restraint ring 1. In order to ensure the continuity of the steel mesh, the distance between the end of the longitudinal rib 6 is greater than 20% of the diameter of the restraint ring for extension use. Multiple core restraint rings 1 are connected to form a steel mesh, and the steel mesh is arranged along the arrangement direction of the wire tube 8.
[0028] In this embodiment, the anchoring hook 5 is a free anchoring hook 5 .
[0029] The use method and advantages of the utility model: When in use, the working process is as follows:
[0030] The utility model is mainly composed of a circular core constraint ring 1, anti-crack reinforcement ribs 4, and longitudinal ribs 6. The construction process is to set and install the special steel mesh after the thin plate template 3 and the bottom ribs are arranged. The assembly of the special steel mesh mainly includes the following steps: first, the parameters of the special steel mesh are determined according to the force requirements. It is mainly composed of a core constraint ring 1, and two fulcrums and protective layer control limbs 2 are set below it. The fulcrum protection limbs are directly placed on the template 3; anti-crack reinforcement ribs 4 are set at both ends of the core constraint ring 1, which are set in the transverse middle section of the core constraint ring 1, and anchor hooks 5 are set at both ends of the anti-crack reinforcement ribs 4. The anchor hooks 5 are placed above the distribution ribs 7. The periphery of the core constraint ring 1 is provided with longitudinal ribs 6, and the wire tube 8 is placed in the core constraint ring 1 and fixed at each intersection. This not only ensures that the problem of cracking caused by insufficient bearing capacity at the concentrated pre-buried area of the wire pipe 8 is solved, but also replaces the difficulty of setting reinforcement ribs and reduces the problem of wire pipe 8 being damaged during construction. It better solves the problem of cracking in the pre-buried area of the floor wire pipe 8, is beneficial to the structural stress, and simplifies the design and construction difficulty.
[0031] The above shows and describes the basic principle, main features and advantages of the utility model. Technical staff in this industry should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model.
