The utility model provides an when installing the outer wall heated board on the hollow brick wall, the not enough problem of effective anchor length of outer wall heat preservation stud to reach the purpose of anchor heated board on the hollow brick wall body.
Description
Technical field
The utility model is suitable for hollow brick Outwall thermal insulation board engineering, in particular to a kind of for the anchor on brick cavity wall
Gu the resistance to plucking peg of insulation board.
Background technique
It is higher and higher to building energy conservation requirement with the fast development of Building Trade in China, it requires in architectural design to building
It builds beyond the region of objective existence wall and carries out energy-saving heat preserving design.Energy-saving heat preserving generally uses external wall insulation, to achieve the purpose that building energy conservation heat insulation.
External wall insulation is that insulation board is fixed on base course wall using exterior-wall heat insulation peg, and the type of base course wall
There are reinforced concrete wall, aerated concrete block work, hollow-brick block wall, exterior-wall heat insulation peg used at present is to pass through metal
Screw extruding plastic expansion pipe causes plastic expansion pipe and base course wall to generate the friction for preventing to pull out outward under the action of extruding force
Power, to achieve the purpose that anchor external wall insulation.
Existing job specfication requirement, effective anchorage depth of the outer wall thermal insulation peg in base course wall are as follows: common mixed
Solidifying cob wall body is not less than 50mm not less than 25mm, hollow brick wall, but the outer wall thickness of hollow brick only has 18mm, has not been able to satisfy
Imitate anchorage length requirement.
Summary of the invention
The purpose of the utility model is to provide a kind of for anchoring the resistance to plucking peg of insulation board, the peg on brick cavity wall
It solves when installing external wall insulation on brick cavity wall, the problem of the valid bonding length deficiency of exterior-wall heat insulation peg, thus
Achieve the purpose that anchor insulation board on hollow brick wall.
As above design, the technical solution of the utility model is: a kind of for anchoring the resistance to plucking of insulation board on brick cavity wall
Peg, it is characterised in that: including the foot section brought disk, the tube expansion that preceding middle section is raised section；The tube expansion front end is hollow to may be stuck in
The swollen plug of brick cavity inner wall, raised section two sides, which are formed with, fills in the sliding slot slid back and forth for swollen；Internal thread processed in the middle part of the swollen plug
Circular hole, swollen plug two sides are formed respectively with a raised line, and the raised line and the sliding slot of tube expansion two sides match；Metal screw screw in tube expansion in and
Tube expansion disk is pushed down in its tail portion, and front end screws in swollen plug.
Above-mentioned bore inner diameter matches with metal screw outer diameter.
The starting point of above-mentioned tube expansion raised section is counted from tail portion disk root, and length is exterior-wall heat insulation plate thickness, exterior wall is levelling
The sum of thickness degree and hollow brick sidewall thickness.
When the utility model is used, being to protrude into the swollen plug in tube expansion front end in hollow brick cavity, tail portion disk is close to heat preservation
After plate, screw front end is screwed in swollen plug with electric drill rotation metal screw, continues rotating metallic screw rod, the external screw thread of metal screw
It fills in swollen to tube expansion tail portion disk (insulation board) Slideslip after being engaged with the internal screw thread of swollen plug, squeezes tube expansion after swollen plug is mobile
It is stuck in lug boss on hollow brick cavity inner wall, so that metal screw is formed tensional element, to reach the anchor on hollow brick wall
Gu the purpose of insulation board.The utility model is solved when installing external wall insulation on brick cavity wall, and exterior-wall heat insulation peg has
The problem of anchorage length deficiency is imitated, is widely applied so that installing insulation board on hollow brick exterior wall.

Specific embodiment
For that can further appreciate that the contents of the present invention, feature and effect, make below by specific embodiment further detailed
State, following implementation be it is descriptive, be not restrictive, this does not limit the scope of protection of the present invention.
It is as shown in the figure: it is a kind of on brick cavity wall anchor insulation board resistance to plucking peg, including the foot section brought disk, it is preceding in
Section is the tube expansion 2 of raised section；The tube expansion front end is the swollen plug 3 that may be stuck in 9 inner wall of hollow brick cavity, and raised section two sides are formed with confession
It is swollen to fill in the sliding slot 4 slid back and forth；Internal thread circular hole processed in the middle part of the swollen plug, swollen plug two sides are formed respectively with a raised line, this is convex
Item and the sliding slot of tube expansion two sides match；Metal screw 1 screws in tube expansion and tube expansion disk is pushed down in its tail portion, and front end screws in swollen
Plug.
Above-mentioned bore inner diameter matches with metal screw outer diameter.
The starting point of above-mentioned tube expansion raised section is counted from tail portion disk root, and length is exterior-wall heat insulation plate thickness, exterior wall is levelling
The sum of thickness degree and hollow brick sidewall thickness.
The specific implementation step of the utility model is as follows:
1, when external wall insulation 7 is installed, first insulation board is pasted on wall screed-coat with adhesive；
2, it is drilled with electric drill in peg position, is bored by the 50% peg position first constructed that peg layout viewing marks
Then resistance to plucking peg is inserted into the hole being drilled by hole；
3, after resistance to plucking peg is inserted into hole, the exposed metal screw end of peg is gently tapped with hand hammer, by metal screw 1
Front end expression lobes section tube expansion 2 forward, makes raised section tube expansion outwardly convex, until metal screw front end touches tube expansion front end
Swollen plug 3, the metal screw then followed closely again with electric drill bolt-revolving, metal screw front end screws in swollen plug after rotating metal screw,
Swollen fill in insulation board side is pulled, so that swollen plug is squeezed tube expansion raised section and tube expansion is stuck in hollow brick cavity inner wall, keep peg golden
Belong to screw rod and form axial tension component, so that insulation board is fixed on 5 wall of hollow brick by resistance to plucking peg；
4, it after the 50% resistance to plucking peg that external wall insulation is first constructed is installed, then constructs and smears on external wall insulation
Face rubber cement is simultaneously pressed into alkali resistant glass fibre open weave cloth, then drill again install remaining 50% resistance to plucking peg, construct second time and plaster
Rubber cement.
