Embodiment 1

[0020] Such as figure 1 As shown, a building material drilling anti-fracture device includes an upper fixing plate 101 and a lower fixing plate 102 arranged parallel to each other, and the two ends of the upper fixing plate 101 and the lower fixing plate 102 are connected by a supporting plate 103 Elastic metal strips 104 are respectively arranged on the opposite end faces of the two support plates 103, and the middle parts of the elastic metal strips 104 are respectively arched toward the side away from the support plates 103, and the elastic metal strips 104 are Strip holes 105 are respectively provided at both ends of the strip 104, threaded holes corresponding to the positions of the strip holes 105 are provided on the support plate 103, and fixing bolts 106 are arranged in the threaded holes. The fixing bolts 106 pass through the threaded holes and the strip holes 105 in turn, and nuts are arranged at the end of the fixing bolts 106 away from the support plate 103, and on...

Embodiment 2

[0024] In this embodiment, on the basis of Embodiment 1, in order to avoid damage to the through hole due to mutual friction between the drill bit and the inner wall of the through hole during the drilling process, in this embodiment, preferably, on the inner wall of the through hole 107, A wear-resistant sleeve 112 is sleeved, and the wear-resistant sleeve 112 is a hollow cylindrical structure, and the wear-resistant sleeve 112 is made of stainless steel.

[0025] In order to facilitate the timely removal of powder and debris generated during the drilling process, in this embodiment, preferably, at least one through groove 109 is provided on the inner wall of the wear-resistant sleeve 112, and the through groove 109 The length direction is parallel to the axial direction of the wear-resistant sleeve 112 . By setting the through-groove structure, during the drilling process, the debris generated by the building materials can be discharged along the through-hole, which is helpf...

Abstract

The invention discloses a drilled building material fracture prevention device which comprises an upper fixing plate and a lower fixing plate that are parallel to each other, wherein the two ends of the upper fixing plate are connected with the two ends of the lower fixing plate through support plates; two elastic metal strips are respectively arranged on the sides of the end faces, which are opposite to each other, of the support plates; the middles of the elastic metal strips are arched towards the sides far away from the support plates respectively; strip-shaped holes are respectively formed in the two ends of the elastic metal strips; threaded holes corresponding to the strip-shaped holes in position are formed in the support plates; and fixing bolts are arranged in the threaded holes. With the adoption of the elastic metal strips and the two fixing plates to fix a to-be-drilled building material from the upper side and the lower side, the fixing of the to-be-drilled building material is realized, and an acting force received by the to-be-drilled building material is buffered in the vertical direction through a rubber gasket layer, so that the building material can be prevented from fracturing and being damaged in a drilling process, and the drilling quality is improved.

Description

technical field [0001] The invention relates to an anti-fracture device for drilling holes of building materials. Background technique [0002] When the building material is drilled, it usually causes cracks around the drilled part. When the force is too large, it will cause the drilled part to break and affect the quality of the drilled hole. Contents of the invention [0003] The object of the present invention is to provide a kind of anti-fracture device for drilling of building materials, which can improve the problems existing in the prior art. By adopting two fixing plate structures to fix the building materials to be drilled from the upper and lower sides, and using elastic metal strips at the same time, it can realize the Hole building materials are fixed, and the force of the building materials to be drilled is buffered in the vertical direction through the rubber cushion, which helps to avoid damage to the building materials during the drilling process, thereby i...
