Description

Technical Field

[0001] This utility model relates to the field of cement fiberboard technology, and in particular to a concealed anchoring cement fiberboard. Background Technology

[0002] Fiber cement board is a new type of building material composed of cement, fiber, fine sand, and other additives. It possesses advantages such as lightweight, high strength, fire resistance, water resistance, sound insulation, heat insulation, and corrosion resistance, and is widely used in construction, decoration, partitions, sound insulation, and fireproofing. Patent application number 202121532475.7 discloses a concealed anchoring fiber cement board, including a board body with an anchoring groove running straight through the back of the board body. The depth direction of the anchoring groove intersects the back of the board body at an angle, thus making the anchor invisible after installation. However, because the anchoring groove is located on the back of the board body, and the depth directions of the upper and lower anchoring grooves are in opposite directions, installation requires the board body to be pushed onto the anchor from one end after the anchoring groove is aligned with the anchor, which is relatively cumbersome. Utility Model Content

[0003] The purpose of this invention is to provide a concealed anchoring cement fiberboard in order to solve the above-mentioned problems.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a hidden anchoring cement fiberboard, including a board body, an upper slot is provided on the upper end surface of the board body, a notch is provided on the back side of the lower end of the board body, the cross-section of the notch is rectangular, and a lower slot is provided on the lower end of the board body in front of the notch.

[0005] Preferably, the front and rear sides of the upper and lower slots are aligned.

[0006] The anchor used for the above-mentioned concealed anchored cement fiberboard includes a channel-shaped body, with an upper insert plate and a lower insert plate respectively provided on the upper and lower sides of the channel-shaped body, and a through hole provided on the bottom plate of the channel-shaped body.

[0007] Compared with the prior art, the present invention has the following advantages: an upper slot is provided on the upper end face of the plate, a notch is provided on the back side of the lower end of the plate, and a lower slot is provided at the lower end of the plate in front of the notch. During installation, the notch can accommodate the groove of the anchor, the lower slot can be fitted downwards onto the upper insert plate, and the lower insert plate can be inserted downwards into the upper slot, which makes installation more convenient.

[0012] To make the utility model's objectives, features, and advantages more apparent and understandable, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below 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 skilled in the art without creative effort are within the scope of protection of the present utility model.

[0013] Detailed implementation method: combined with Figure 1-3 As shown, a concealed anchoring cement fiberboard includes a board body. An upper slot 1 is provided on the upper end face of the board body, and a notch 3 is provided on the back side of the lower end of the board body. The cross-section of the notch 3 is rectangular. A lower slot 2 is provided at the lower end of the board body in front of the notch 3. The cross-sections of the upper slot 1 and the lower slot 2 are rectangular and their extension direction is parallel to the extension direction of the board body.

[0014] Furthermore, the front and rear sides of the upper slot 1 and the lower slot 2 are aligned, that is, the front side of the upper slot 1 and the front side of the lower slot 2 are on the same plane, and the rear side of the upper slot 1 and the rear side of the lower slot 2 are on the same plane.

[0015] The anchor 4 used for the above-mentioned concealed anchored cement fiberboard includes a channel-shaped body. The two side plates of the channel-shaped body are perpendicular to the bottom plate. The upper and lower sides of the channel-shaped body are respectively provided with an upper insert plate 41 and a lower insert plate 42. The upper insert plate 41 and the lower insert plate 42 are parallel to the bottom plate of the channel-shaped body. The bottom plate of the channel-shaped body is provided with a through hole. During installation, a self-tapping screw is passed through the through hole and connected to the light steel keel.

[0016] During installation, first fix two anchors 4 to the light steel keel. The two anchors 4 are at the same height and the distance between them is less than the length of the plate. Then, place the plate on the two anchors 4 from top to bottom, and insert the upper plate 41 into the lower slot 2. Next, insert the lower plates 42 of the third and fourth anchors 4 into the upper slot 1, and then fix the third and fourth anchors 4 to the light steel keel. At this point, the plate is fixed. Then, place the second plate on the third and fourth anchors 4 from top to bottom, and insert the upper plate 41 into the lower slot 2. Then, fix the upper end of the second plate in the same way as before. The groove is located in the notch 3 and is thus hidden, and the anchors 4 are almost invisible. Then, multiple plates can be fixed to the light steel keel in sequence in the above manner. The installation is relatively simple and easy to operate.

[0017] The above-described embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
