Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to an internal pull-type non-removable high-strength concrete fiber formwork and its accessory structure. Background Technology

[0002] Chinese patent discloses an internally pulled, non-removable high-strength concrete fiber formwork (application number 202321618524.8), comprising a high-strength concrete fiberboard and multiple internally pulled members. Each internally pulled member includes a nut and a screw. The nut is embedded and fixed within the high-strength concrete fiberboard, and the screw is threadedly connected to the nut, protruding from the high-strength concrete fiberboard. A connecting portion is provided at the protruding part of the screw. The inner and outer layers of high-strength concrete fiber formwork constituting the building wall are connected by a pull rod, with both ends of the pull rod connected to the connecting portions on the inner and outer layers of the high-strength concrete fiber formwork, respectively. A reinforcing mesh is also provided within the internally pulled, non-removable high-strength concrete fiber formwork. A base plate is provided at the end of the nut away from the screw, and the base plate is fixedly connected to the reinforcing mesh. In use, concrete needs to be poured into the cavity between the inner and outer layers of internally tensioned, non-removable high-strength concrete fiber formwork to form the building wall. During the concrete pouring process, the internally tensioned, non-removable high-strength concrete fiber formwork needs to withstand significant lateral pressure and tensile stress. Therefore, it is necessary to ensure that the internally tensioned, non-removable high-strength concrete fiber formwork has good load-bearing performance to prevent deformation and cracking. In view of this, we propose an internally tensioned, non-removable high-strength concrete fiber formwork and its accessory structure to solve the technical problems existing in the prior art. Utility Model Content

[0003] The purpose of this utility model is to provide an internally tensioned, non-removable high-strength concrete fiber formwork and its accessory structure to solve the problems existing in the prior art. It can improve the stress performance of the internally tensioned, non-removable high-strength concrete fiber formwork, making it less prone to deformation and cracking, thus improving product quality.

[0004] To achieve the above objectives, this utility model provides the following solution:

[0005] This utility model provides an accessory structure for an internally pulled, non-removable high-strength concrete fiber formwork, including a reinforcing mesh, a nut, and a base plate. The reinforcing mesh includes longitudinal wires and transverse wires, which are perpendicular to each other and fixedly connected. The transverse wires are located on one side of the longitudinal wires. The longitudinal wires have a bent section that bends downward toward the side where the transverse wires are located. The base plate is fixed in the groove formed by the bent section. One side of the base plate abuts against the bottom of the groove formed by the bent sections of two adjacent longitudinal wires. The thickness of the base plate is not greater than the depth of the groove. The nut is located between two adjacent longitudinal wires that abut against the base plate. One end of the nut is fixed to the base plate, and the other end extends toward the side where the transverse wires are located.

[0006] In one embodiment, the longitudinal and transverse wires are steel wires, and the base plate is a steel plate.

[0007] In one embodiment, the intersection of the longitudinal wire and the transverse wire is welded and fixed.

[0008] In one embodiment, the base plate is welded into the groove.

[0009] In one embodiment, the bent segments are provided at intervals along the length direction of the longitudinal wire.

[0010] In one embodiment, the thickness of the base plate is equal to the groove depth.

[0011] In one embodiment, the base plate is a cylindrical base plate, the nut is a cylindrical nut, and the base plate and the nut are arranged coaxially.

[0012] In one embodiment, the base plate and the nut are integrally formed.

[0013] In one embodiment, the reinforcing mesh, the nut, and the base plate are all provided with an anti-corrosion coating.

[0014] This utility model also provides an internally pulled, non-removable high-strength concrete fiber formwork, including the accessory structure of the internally pulled, non-removable high-strength concrete fiber formwork described above.

[0015] The present invention achieves the following technical advantages over the prior art:

[0016] This utility model provides an internal pull-type, non-removable high-strength concrete fiber formwork and its accessory structure, including a reinforcing mesh, nuts, and a base plate. The reinforcing mesh includes longitudinal wires and transverse wires, which are perpendicular to each other and fixedly connected. The transverse wires are located on one side of the longitudinal wires. A bent section is provided on the longitudinal wire, bending downwards towards the side where the transverse wire is located. The base plate is fixed within the groove formed by the bent section. One side of the base plate abuts against the bottom of the groove formed by the bent sections of two adjacent longitudinal wires. The thickness of the base plate is not greater than the depth of the groove. Nuts are provided on the two adjacent longitudinal wires abutting against the base plate. Between the wires, one end of the nut is fixed to the base plate, and the other end extends towards the side where the horizontal wire is located. This prevents the base plate from protruding from the vertical wire and avoids adding extra thickness to the reinforcing mesh protective layer. This allows for better control of the thickness of the reinforcing mesh protective layer, thus forming a uniformly thick concrete protective layer on the outside of the reinforcing mesh when making internally pulled, non-removable high-strength concrete fiber formwork. This improves the stress performance of the internally pulled, non-removable high-strength concrete fiber formwork and avoids deformation and cracking problems caused by the protrusion of the base plate.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] The purpose of this utility model is to provide an internally tensioned, non-removable high-strength concrete fiber formwork and its accessory structure to solve the problems existing in the prior art. It can improve the stress performance of the internally tensioned, non-removable high-strength concrete fiber formwork, making it less prone to deformation and breakage, thus improving product quality.

[0026] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0027] Example 1

[0028] like Figures 1-2 As shown, this utility model provides an accessory structure for an internally pulled, non-removable high-strength concrete fiber formwork, including a reinforcing mesh 1, a nut 2, and a base plate 3. The reinforcing mesh 1 includes longitudinal wires 11 and transverse wires 12. The longitudinal wires 11 and transverse wires 12 are perpendicular to each other and fixedly connected. The transverse wires 12 are arranged on one side of the longitudinal wires 11. Figure 2 The transverse wire 12 is located above the longitudinal wire 11. There are no fewer than 4 longitudinal wires 11 and no fewer than 3 transverse wires 12. The longitudinal wires 11 and transverse wires 12 are fixedly connected to form a planar mesh structure. The longitudinal wires 11 are provided with a bent section 111 that bends downward toward the side where the transverse wire 12 is located. The base plate 3 is fixed in the groove formed by the bent section 111. One side of the base plate 3 abuts against the bottom of the groove formed by the bent sections 111 of two adjacent longitudinal wires 11. The thickness of the base plate 3 is not greater than the depth of the groove. The nut 2 is located between two adjacent longitudinal wires 11 that abut against the base plate 3. One end of the nut 2 is fixed to the base plate 3, and the other end extends toward the side where the transverse wire 12 is located.

[0029] The base plate 3 is fixed in the groove formed by the bent section 111. The thickness of the base plate 3 is not greater than the depth of the groove, so that the base plate 3 will not protrude from the longitudinal wire 11 and will not increase the thickness of the reinforcing mesh 1 protective layer. This allows for better control of the thickness of the reinforcing mesh 1 protective layer. As a result, when making the internal pull-type non-removable high-strength concrete fiber formwork, a uniformly thick concrete protective layer 6 can be formed on the outside of the reinforcing mesh 1, thereby improving the stress performance of the internal pull-type non-removable high-strength concrete fiber formwork and avoiding the deformation and cracking of the internal pull-type non-removable high-strength concrete fiber formwork caused by the protrusion of the base plate 3. Furthermore, the base plate 3 will not be exposed.

[0030] In this embodiment, the longitudinal wire 11 and the transverse wire 12 are steel wires, and the base plate 3 is a steel plate. The base plate 3 is welded into the groove formed by the bending section 111. The intersection of the longitudinal wire 11 and the transverse wire 12 is welded and fixed. The diameter of the longitudinal wire 11 and the transverse wire 12 is not less than 2.5mm. The reinforcing mesh 1, the nut 2, and the base plate 3 are all treated with anti-corrosion coating, and their surfaces are all provided with an anti-corrosion coating, such as a galvanized layer.

[0031] In this embodiment, multiple bending segments 111 are spaced apart along the length of the longitudinal wire 11. The number can be set differently according to actual needs.

[0032] In this embodiment, the thickness of the base plate 3 is equal to the depth of the groove, so that the side of the base plate 3 facing away from the bottom of the groove is flush with the side of the longitudinal wire 11 facing away from the transverse wire 12.

[0033] In this embodiment, the base plate 3 is a cylindrical base plate, and the nut 2 is a cylindrical nut. The diameter of the base plate 3 is larger than the diameter of the nut 2, and the base plate 3 and the nut 2 are arranged coaxially. Other shapes are also possible in practical applications. The base plate 3 and the nut 2 are integrally formed.

[0034] Example 2

[0035] like Figures 3-5 As shown, this embodiment provides an internally tensioned, non-removable high-strength concrete fiber formwork, including the accessory structure of the internally tensioned, non-removable high-strength concrete fiber formwork described in Embodiment 1.

[0036] During the fabrication of the internally tensioned, non-removable high-strength concrete fiber formwork, the accessories of the internally tensioned, non-removable high-strength concrete fiber formwork described in Example 1 are pre-embedded inside the internally tensioned, non-removable high-strength concrete fiber formwork. The lengths of the longitudinal wires 11 and transverse wires 12 of the reinforcing mesh 1 are determined according to the external dimensions of the internally tensioned, non-removable high-strength concrete fiber formwork. The length of the longitudinal wire 11 is 20-40 mm shorter than the longitudinal side length of the internally tensioned, non-removable high-strength concrete fiber formwork, and the length of the transverse wire 12 is 20-40 mm shorter than the transverse side length of the internally tensioned, non-removable high-strength concrete fiber formwork.

[0037] In use, first screw the screw 4 into the nut 2 for threaded connection. Then, splice multiple inner-pull, non-removable high-strength concrete fiber templates to form an inner inner-pull, non-removable high-strength concrete fiber template and an outer inner-pull, non-removable high-strength concrete fiber template. The nuts 2 on the inner and outer inner-pull, non-removable high-strength concrete fiber templates are threaded with screws 4 and pull rings 5. The pull rings 5 ​​and screws 4 are integrally formed. The inner and outer inner-pull, non-removable high-strength concrete fiber templates are connected by tie rods. The tie rods are steel bars with hooks at both ends. The hooks of the tie rods are used to insert into the pull rings 5, so that the inner and outer inner-pull, non-removable high-strength concrete fiber templates are connected to each other and form a cavity.

[0038] It should be noted that screw 4 and pull ring 5 have also undergone anti-corrosion treatment, and their surfaces are covered with anti-corrosion coatings (such as anti-corrosion zinc coatings).

[0039] It should be noted that the pull ring 5 mentioned in the text is circular, but in actual applications, the pull ring is not limited to a circle; it can also be elliptical or other shapes.
