Technical Field

[0001] The present application relates to the field of embedded channels, and in particular to a tensile embedded channel. Background Art

[0002] Embedded channel is a prefabricated component widely used in the field of construction and engineering, mainly used in concrete structures. It is a steel or plastic trough-shaped component pre-installed in the formwork before concrete pouring, and is used to fix various structural components in the later stage, such as pipes, cables, steel bars, etc. The use of embedded channel can improve the integrity and durability of the structure, while simplifying the construction process and reducing the later excavation and drilling work.

[0003] In the related art, an anchor rod is usually welded on the side of the channel body away from the notch to improve the stability of the channel body in the concrete. However, when the channel body needs to connect a component with a strong tensile force, the anchoring effect of the anchor rod alone is limited. Utility Model Content

[0014] Optionally, a protrusion is provided on a side of the resistance rib away from the channel body, and the protrusion extends in a direction away from the anchor rod.

[0015] By adopting the above technical solution, the protrusions can be used to further improve the anchoring effect of the resistance ribs, thereby improving the overall anchoring strength of the channel body.

[0016] Optionally, the outer walls of the channel body located on both sides of the slot opening are provided with anchoring grooves along the length direction.

[0017] By adopting the above technical solution and providing anchor grooves, the concrete can limit the channel body perpendicular to the surface of the concrete component, thereby improving the pull-out resistance of the channel body.

[0020] Optionally, the slot of the slot body is configured as a dovetail slot.

[0021] By adopting the above technical solution, the dovetail groove is used to improve the stability of the connection between the channel body and other components.

[0022] Optionally, the slot of the slot body is filled with a filler.

[0023] By adopting the above technical solution, the filler can prevent the concrete slurry from penetrating into the slot, thereby avoiding affecting the subsequent laying of wire pipes or connection of other components in the slot.

[0034] The following is combined with Figure 1-5 This application is described in further detail.

[0035] A tensile embedded channel, refer to Figure 1 and Figure 2 , including a channel body 1 and a plurality of anchor rods 2, the plurality of anchor rods 2 are all fixed on the side wall of the channel body 1 away from the channel opening, and the plurality of anchor rods 2 are evenly distributed along the length direction of the channel body 1. At the same time, the side walls of the channel body 1 on both sides of the channel opening are penetrated by a plurality of anchoring steel bars 3, the anchoring steel bars 3 pass through both sides of the channel body 1, and are located on the side of the channel body 1 close to the anchor rods 2.

[0036] During construction, the channel body 1, anchor rods 2 and anchor steel bars 3 are poured into the concrete together. The anchor steel bars 3 can form a stable anchoring effect, significantly improve the pull-out resistance of the channel body 1, and improve the stability of the channel body 1 in the concrete component, so that the channel body 1 can be connected to components with strong tensile force.

[0037] Specifically, refer to Figure 1 and Figure 2The anchor rod 2 includes a welding plate 21, a connecting plate 22 and an anchoring plate 23. The two ends of the connecting plate 22 are respectively fixed to the plate surface of the welding plate 21 and the plate surface of the anchoring plate 23. The three together form an "I"-shaped structure. The welding plate 21 is welded and fixed to the channel body 1. After the anchoring plate 23 is cast in the concrete component, a good pull-out resistance effect can be formed. In addition, compared with the conventional rod body, the contact area between the welding plate 21 and the channel body 1 is larger, and the connection is more firm.

[0038] Preferably, the anchoring steel bar 3 is arranged parallel to the side wall of the channel body 1 away from the notch. With the above structure, when the channel body 1 is subjected to tension, the force direction of the tension is perpendicular to the axial direction of the anchoring steel bar 3, ensuring the anchoring effect of the anchoring steel bar 3.

[0039] Preferably, the anchor rod 2 steel bars are tied and fixed to the steel mesh in the concrete member to further improve the stability of the anchor rod 2 steel bars in the concrete member and enhance the pull-out resistance of the channel body 1.

[0040] Preferably, according to the construction requirements, the notch of the channel body 1 can be set as a dovetail groove to improve the stability of the connection between the channel body 1 and other components.

[0041] Further, refer to Figure 2 The slot of the channel body 1 is filled with a filler 4. The filler 4 can prevent the concrete slurry from penetrating into the slot, thereby avoiding affecting the subsequent laying of wire pipes or connecting other components in the slot.

[0042] Embodiment 1:

[0043] Reference Figure 3 The outer walls of the channel body 1 on both sides of the notch are provided with anchor grooves 5 along the length direction, that is, the two sides of the channel body 1 are recessed inward. After the channel body 1 is poured into the concrete component, the concrete fills the anchor grooves 5, which increases the contact area between the channel body 1 and the concrete. At the same time, the concrete in the anchor grooves 5 forms an anchoring force that prevents the channel body 1 from being pulled out, further improving the pull-out strength of the channel body 1.

[0044] The implementation principle of Example 1 of the present application is: anchor grooves 5 are opened on both sides of the channel body 1 so that the concrete can form a limiting effect on the channel body 1 perpendicular to the surface of the concrete component to improve the pull-out resistance of the channel body 1.

[0045] Embodiment 2:

[0046] Reference Figure 4The side walls of the channel body 1 on both sides of the notch are provided with resistance ribs 6, which are arranged along the length direction of the channel body 1 and extend perpendicularly to the side walls of the channel body 1 in a direction away from the channel body 1. When the channel body 1 is subjected to tension in the concrete member, the resistance ribs 6 can cooperate with the concrete to form a pull-out resistance to improve the pull-out resistance of the channel body 1.

[0047] Further, refer to Figure 5 A protrusion 7 is provided on the side of the resistance rib 6 away from the channel body 1, and the protrusion 7 extends in a direction away from the anchor rod 2. The protrusion 7 can further improve the anchoring effect of the resistance rib 6, thereby improving the overall anchoring strength of the channel body 1.

[0048] The implementation principle of Example 2 of the present application is: after the channel body 1 is cast into the concrete component, the concrete forms a limiting effect on the resistance ribs 6. When the channel body 1 is subjected to tension in the concrete component, the concrete forms a tensile reaction force through the resistance ribs 6 to improve the pull-out strength of the channel body 1.

[0049] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
