Abstract
The invention discloses a bolt easy to be fixed on the hollow block wall face, comprising a screw, a gasket and a nut, wherein the gasket and the nut are sleeved on the screw. The tail end of the screw is provided with a notch comprising the diameter along the direction of a central line, the notch is internally articulated with an off-center clamping sheet through a cylindrical pin, the clamping sheet is provided with a near-screw end, a far-screw end, a near-screw tail end side and a far-screw tail end side, and the near-screw end is positioned in the notch of the screw when the direction of the length of the clamping sheet is parallel to the central line of the screw. The invention can be conveniently and fast installed on the hollow block wall face and can improve operating efficiency.
Description
Technical field
The present invention relates to a kind of threaded connector, particularly a kind ofly be convenient on hollow block wall face fixing bolt.
Background technique
The fixation principle of traditional setscrew: setscrew is made up of parts such as screw rod and expansion tubes, and screw rod tail is coniform, and the diameter of circular cone is greater than the expansion tube internal diameter.In the time of nut screwing clamping, screw rod outwards moves, and by moving axially of screw thread tapered segment is moved, and then form very big positive pressure at the outer circumferential face of expansion tube, the angle of circular cone is very little in addition, forms friction self-locking thereby make between body of wall, expansion tube and circular cone, and then reaches fixation.
Because requirements such as environmental protection, the infilled wall of building is many builds by laying bricks or stones with building-block.The production hollow brick is compared with solid brick and can be saved clay 20%-30%, fuel saving 10%-20%, and brick embryo sintering is even, burns till the rate height, adopts hollow brick can reduce dead load about 1/3, improves work efficiency 40%, can also improve the thermal property of body of wall simultaneously.Hollow brick since its various advantages be widely adopted, adopt traditional setscrew then can not rely on and body of wall between friction insist on power.Thereby in the use of reality, brick cavity wall is carried out after " pre-buried " handle, could fastening effectively setscrew.
Summary of the invention
The present invention provides a kind of bolt fixing on hollow block wall face of being convenient to for solving the technical problem that exists in the known technology, and this bolt is convenient to carry out fixed operation on hollow block wall face, can improve the operation effect.
The present invention for the technological scheme that solves the technical problem that exists in the known technology and take is: a kind ofly be convenient to bolt fixing on hollow block wall face, comprise screw rod and the packing ring and the nut that are sleeved on the screw rod, the tail end of described screw rod has the notch that comprises its diameter along its centerline direction, be hinged with the card of biasing in the described notch by straight pin, described card is provided with nearly screw rod end, screw rod end far away, nearly screw rod tail end-side and screw rod tail end-side far away, when the length direction of described card was parallel with the center line of described screw rod, the nearly screw rod end of described card was positioned at the notch of described screw rod.
Be provided with chamfering or knuckle between the nearly screw rod end of described card and its screw rod tail end-side far away.
The related parameter that has of described card and described screw rod satisfies: L
1=1.5D, L
2=2.5D, K=D, L=2.5D; Wherein, L
1Be the distance between nearly screw rod end of card and the straight pin, L
2Be the distance between card screw rod end far away and the straight pin, K is the card width, and L is the length of notch, and D is a screw diameter.
The related parameter that has of described card, described screw rod and described straight pin satisfies: t=3～5mm, t
1=t+5～6mm, D
1=0.3D～0.5D; Wherein t is a card thickness, t
1Be the width of notch, D
1Be the straight pin diameter.
Advantage and good effect that the present invention has are: adopt and have the notch that comprises its diameter along its centerline direction at the screw rod tail end, in notch, be hinged with the card of biasing by straight pin, when the length direction of card is parallel with the center line of screw rod, the nearly screw rod end of card can be positioned at the structure of the notch of screw rod, this bolt can be installed on the hollow block wall face quickly and easily, can improve the operation work efficiency.If with traditional setscrew, then process is very loaded down with trivial details: will empty near the locating point earlier, wooden unit is beyond the Great Wall beaten setscrew on wooden unit the method that perhaps adopts chemical grouting to reinforce again then.
Description of drawings
Fig. 1 is a structural representation of the present invention;
Fig. 2 is the plan view of screw rod of the present invention.
Among the figure: 1, screw rod, 2, packing ring, 3, nut, 4, straight pin, 5, card, the nearly screw rod end of 5-1, card, the screw rod end far away of 5-2, card, 5-3, nearly screw rod tail end-side, 5-4, screw rod tail end-side far away.
Embodiment
For further understanding summary of the invention of the present invention, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:
For bolt is fixed on the hollow concrete block wall securely, avoid using the complexity " pre-buried " of conventional expanded bolt to handle, present embodiment has proposed this bolt that is applicable to that hollow block wall face is fixing.
See also Fig. 1～Fig. 2, the present invention is a kind of is convenient to bolt fixing on hollow block wall face, comprise screw rod 1 and the packing ring 2 and the nut 3 that are sleeved on the screw rod 1, the tail end of described screw rod 1 has the notch that comprises its diameter along its centerline direction, be hinged with the card 5 of biasing in the described notch by straight pin 4, described card 5 is provided with nearly screw rod end 5-1, screw rod end 5-2 far away, nearly screw rod tail end-side 5-3 and screw rod tail end-side 5-4 far away., when the length direction of described card 5 was parallel with the center line of described screw rod 1, the nearly screw rod end 5-1 of described card was positioned at the notch of described screw rod 1.Be provided with chamfering or knuckle between the nearly screw rod end 5-1 of described card and its screw rod tail end-side 5-4 far away.
The related parameter that has of described card 5 and described screw rod 1 and described straight pin satisfies: L
1=1.5D, L
