Description

Hidden anchoring type fiber cement board

Technical Field

The utility model relates to a decorative board technical field, in particular to hide anchor formula fiber cement board.

Background

The installation method of the fiber cement board in the prior art mainly comprises the following three types:

first, grooves are formed in the peripheral parts of the fiber cement board, and then the decoration board is fixed on the wall body through hanging pieces.

And secondly, punching through holes on the fiber cement board, and fixing the decorative board on the wall body through anchor bolts.

Thirdly, back bolt holes are drilled on the back of the fiber cement board and then the fiber cement board is fixed on the wall body through back bolts and hanging pieces

In the third mode, the anchor bolt and the hanging piece are covered by the decorative plate, the front surface of the anchor bolt and the hanging piece is invisible, and the anchor bolt and the hanging piece are mainly used for an open type curtain wall structure. However, the difficulty of drilling the back bolt connecting hole on the fiber cement board is high, the back bolt connecting hole is a blind hole with a large bottom and a small opening, the periphery of a cutter is surrounded by the back bolt connecting hole in the machining process, the heat dissipation condition of the cutter is poor, and in order to solve the technical problem that the cutter is quickly worn due to poor heat dissipation in the machining process, a water drill is usually adopted for drilling the back bolt connecting hole, but the water absorption rate of the fiber cement board is high, and the water drill can cause the water content of the fiber cement board to be too high when the back bolt connecting hole is machined. Meanwhile, the back bolts are in point-like mechanical anchoring, the anchoring forces of different back bolt anchoring points on the same cement fiber board are difficult to be balanced and consistent, even a part of the anchoring points are not stressed, and therefore the reliability of the overall mechanical performance of the fiber cement board anchored by the back bolts is low.

SUMMERY OF THE UTILITY MODEL

In view of this, the utility model aims at providing a hide anchor formula fiber cement board to solve the technical problem that cutter heat dissipation condition is poor, whole anchor mechanics reliability is low when cement fiberboard adopts the back of the body bolt anchor to have drilling.

The utility model discloses hide anchor formula fiber cement board, the package rubbing board body is provided with the anchor groove that runs through the plate body back along the straight line on the plate body back, the groove depth direction in anchor groove intersects with the slope of the plate body back.

Further, the anchoring grooves are provided at upper and lower sides of the back surface of the plate body.

Furthermore, the number of the anchoring grooves on the upper side of the back surface of the plate body is one or two, and the number of the anchoring grooves on the lower side of the back surface of the plate body is one or two.

Furthermore, two anchor grooves on the upper side of the back of the plate body and two anchor grooves on the lower side of the back of the plate body are arranged in a splayed shape.

Further, the anchoring groove is also arranged in the middle of the back of the plate body.

The utility model has the advantages that:

1. the utility model discloses hide anchor formula fiber cement board, the anchor groove at the plate body back can not surround the cutter all around like the connecting hole is tied to the back of the body in the course of working, therefore the cutter has good heat dissipation space, need not cool off the heat dissipation to the cutter with the water in the course of working, and then has eliminated current cement fiberboard and has tied the technical problem that the connecting hole in-process can increase mud fiberboard moisture content at the processing back of the body.

2. The utility model discloses hide anchor formula fiber cement board, the anchor groove of its run-through forms linear mechanical anchor with anchor assembly when cooperating, and this makes the atress of cement fiberboard balanced, for adopting this kind of punctiform mechanical anchor of back of the body bolt, the utility model discloses hide anchor formula fiber cement board's whole anchor mechanics reliability is higher.

Detailed Description

The invention is further described with reference to the following figures and examples.

As shown in fig. 2, the hidden anchoring type fiber cement board of the embodiment includes a board body 1, an anchoring groove 2 is provided on the back surface of the board body and penetrates through the back surface of the board body along a straight line, and the groove depth direction of the anchoring groove is obliquely intersected with the back surface of the board body. In specific implementation, the length direction of the anchoring groove can be parallel to the edge part of the plate body, and can also be obliquely intersected with the edge part of the plate body; the angle of the inclined intersection of the groove depth direction of the anchoring groove and the back surface of the plate body is preferably 30-60 degrees or 120-150 degrees.

In this embodiment, the anchor groove sets up the upside and the downside at the plate body back, and both sides all set up the anchor groove about the backplate, assurance fiber cement board's that can be better anchor reliability.

In this embodiment, the anchor groove of plate body back upside is twice, and the anchor groove of plate body back downside also is twice, and the twice anchor groove of plate body back upside and the twice anchor groove of plate body back downside all are the splayed and arrange. As shown in fig. 4, the splayed anchoring groove is engaged with the anchoring member 4, and the fiber cement board can be reliably riveted and fixed. Of course, in different embodiments, as shown in fig. 3, the anchoring grooves on the upper side of the back surface of the plate body and the lower side of the back plate can also be one or two. In this embodiment, the hidden anchoring type fiber cement board has a through-type anchoring groove which forms a linear mechanical anchoring when being matched with the anchoring member, so that the cement fiber board is stressed evenly, and compared with a back bolt which is a punctiform mechanical anchoring, the hidden anchoring type fiber cement board in this embodiment has higher mechanical reliability of overall anchoring.

As an improvement to the above embodiment, the anchoring grooves are further disposed in the middle of the back surface of the plate body, the number of the anchoring grooves is determined according to the size of the fiber cement plate, and for the fiber cement plate with a larger size, the anchoring reliability can be further improved by disposing the anchoring grooves in the middle.

Finally, although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the present invention can be modified or replaced by other means without departing from the spirit and scope of the present invention, which should be construed as limited only by the appended claims.
