The other end is embedded in new wall.
A kind of preferred scheme is the steel mesh that new and old wall joint connecting device also includes that cross section is L-shaped, the vertical plane of steel mesh
It is embedded in by concrete in cannelure, the horizontal plane of steel mesh is fixed by nail pressing with new wall, and is embedded in new wall.
A kind of preferred scheme is that upper fragment of brick and lower fragment of brick in new wall mutually stagger, and upper fragment of brick and lower fragment of brick formation
Vertical seam, adjacent vertical seam spacing is 1/2 or quarter brick block length.
A kind of preferred scheme is the width 8mm~12mm stitched vertically.
A kind of preferred scheme is that the width stitched vertically is 10mm.
A kind of preferred scheme is that bolt hole is located between the neighbouring fragment of brick in old wall, and the hole depth of bolt hole is
60mm。
A kind of preferred scheme is to be provided with two row's bolts hole in cannelure from top to bottom.
A kind of preferred scheme is that longitudinal groove depth is 15mm~30mm.
Summary technical scheme, the beneficial effects of the utility model：New wall and old wall connecting are firm, it is ensured that matter
Amount；Avoid cracking phenomenon at new wall and old wall connecting.
Described above is only the general introduction of technical solutions of the utility model, in order to better understand skill of the present utility model
Art means, and being practiced according to the content of specification, and in order to allow above and other purpose of the present utility model, feature
It can be become apparent with advantage, below especially exemplified by preferred embodiment, and coordinate accompanying drawing, describe in detail as follows.
Brief description of the drawings
Fig. 1 is top view of the present utility model.
Embodiment
As shown in figure 1, a kind of new and old wall joint connecting device, for connecting new wall 100 and old wall 101, old wall
101 surfaces are provided with cannelure, alternate from top to bottom in cannelure to be provided with some bolts hole, in addition to expansion bolt 103, expansion
In one end stud bolt hole of bolt 103, the other end is embedded in new wall 100.
As shown in figure 1, in one end stud bolt hole of expansion bolt 103, the other end is embedded in new wall 100, therefore makes
Obtain new wall 100 and old wall 101 to be connected firmly, it is ensured that quality.
As shown in figure 1, new and old wall joint connecting device also includes the steel mesh that cross section is L-shaped, the vertical plane of steel mesh passes through
Concrete is embedded in cannelure, and the horizontal plane of steel mesh is fixed by nail pressing with new wall 100, and is embedded in new wall 100.
The steel mesh of L-shaped further increases new wall 100 and the junction fastness of old wall 101, it is to avoid new wall and old wall connecting
Locate cracking phenomenon.
As shown in figure 1, the upper fragment of brick and lower fragment of brick in new wall 100 mutually stagger, and upper fragment of brick and the formation of lower fragment of brick
Vertical seam, adjacent vertical seam spacing is 1/2 or quarter brick block length.Width 8mm~the 12mm stitched vertically.In the utility model, erect
The width of vertical masonry joint is 10mm.
Between neighbouring fragment of brick of the bolt hole in old wall 101, the hole depth of bolt hole is 60mm.In cannelure
Two row's bolts hole are provided with from top to bottom.
When building a wall, new wall 100 and old wall 101 junction will destroy the plaster layer of former wall, and (width is every for width of building a wall
Side+150MM)；
On old wall, from ground to smallpox, (centre position of 2 pieces of brickwork joints up and down) punches 2 with 8mm drill bits at 400MM
Individual, hole depth is 60mm；
Φ 6*40mm expansion bolts 103 are inserted in 2 holes respectively, real expansion bolt 103 are struck with iron hammer, until expanding screw
Top is untill the bottom in hole completely for bolt 103, the nut screwed up with a wrench on expansion bolt 103, checks that expansion bolt 103 does not loosen
Untill；
The horizontal joint of brickwork joint and vertical slit width degree are generally 10mm, but should not be less than 8mm, also not should be greater than 12mm.
During plaster, the seam between new wall 100 and old wall 101 must hang 1*10*10MM, a width of 300MM (new and old walls
Each 150MM) steel mesh ability plaster, plaster thickness degree is 15mm -30mm, and steel mesh is not exposed, and steel mesh is fixed with nail pressing, concrete
The scope of operation fixes steel mesh with nail-free glue.
Above is embodiment of the present utility model, it is noted that for those skilled in the art
For, on the premise of the utility model principle is not departed from, some improvements and modifications can also be made, these improvements and modifications
It is considered as protection domain of the present utility model.
