The embodiment of the present invention provides a kind of reinforcement means of historical building blocking partition wall, and this method is used for historical building
The wall body structure of blocking partition wall is reinforced, to avoid it is subsequent displacement, be assembled into whole face wall process in its wall
It damages.The historical building blocking partition wall refer to whole face historical building wall is planned to according to column, axis relationship it is several
A blocking partition wall 1.Every module unit partition wall includes a brick column, a face wall, a door or window, the height of blocking wall
For a layer height.
After each unit partition wall 1 of historical building wall top layer is reinforced into unit combined wall 3, then it is compound in unit
Temporary support blocks are installed, each unit partition wall of top layer cut, handling on wall 3.After the completion of the wall cutting of top layer,
Remaining floor is cut according still further to the above method, handling.It, can be in factory to each list after the completion of the cutting of historical building wall
First combined wall is repaired, is assembled.
Specifically, the reinforcement means of the historical building blocking partition wall of the application, specifically includes the following steps:
Step 1: in the support construction 9 of 1 bottom of blocking partition wall setting ground beam；
Specifically, firstly, equidistantly opening up multiple support slots 4 in the bottom of blocking partition wall 1, as soon as a support slot 4 is often opened up,
A split heads 5 is placed in the support slot；The height of split heads 5 and the height of support slot 4 match, so that split heads 5 can be propped up effectively
Hold upper and lower two blocking partition walls 1.
Each 5 lower section of split heads is placed with the isolation board 6 of a 5mm thickness.
In the present embodiment, the split heads 5 is made of a cube steel bar framework and two steel plates, and two steel plates are solid respectively
The top and bottom of cube steel bar framework are scheduled on, the area of steel plate is greater than the area of cube steel bar framework top/bottom.When
After split heads 5 is placed in support slot 4, the steel plate at 5 top of split heads is in contact with blocking partition wall 1.
After the split heads 5 of blocking partition wall bottom places, the wall of all split heads neighbours side is removed, makes blocking partition wall bottom
Portion forms multiple empty slots 7 separated by split heads；
Then, the isolation board of a 5mm thickness is placed respectively in each empty slot, the isolation board in empty slot and being isolated below split heads
Plate is using the isolation board of same material, and in the present embodiment, the isolation board below the isolation board and split heads in empty slot is used
Be 5mm thickness PVC plastic backing plate, separated between such upper unit partition wall and lower layer's wall by one layer of plastic base plate.
Finally, spacer bar 8 is sequentially passed through each split heads, the split heads all with 1 lower section of blocking partition wall of spacer bar 8
5 collectively constitute an entirety, constitute the support construction 9 of ground beam.The diameter of ground beam main reinforcement is 12mm.
The spacer bar 8 is made of multiple stirrups being spacedly distributed, the rod-shaped reinforcing bar being fixed on stirrup, and stirrup is straight
Diameter is 8mm, and the spacing between two neighboring stirrup is 150mm, and the diameter of rod-shaped reinforcing bar is 12mm.When spacer bar 8 is threaded through
After in split heads 5, by spacer bar 8 together with each 5 binding and fixing of split heads, support construction 9 is constituted.The entirety of support construction 9
Height is not less than 50 centimeters.
Step 2: it is implanted into tension rib at the back side of blocking partition wall 1, then in 1 back side assembling reinforcement mesh sheet of blocking partition wall,
Reinforced mesh and support construction and wall tie bar carry out binding and fixing.
For the tension rib at 1 back side of blocking partition wall in being spacedly distributed, tension rib diameter is 8mm, two neighboring tension rib it
Between spacing be 500mm.
Reinforced mesh is as longitudinal reinforcement and transverse steel right-angled intersection by mesh sheet made of binding or welding production, horizontal
Diameter to reinforcing bar and longitudinal reinforcement is 10mm, the spacing and two neighboring longitudinal reinforcement between two neighboring transverse steel it
Between spacing be 200mm.
Step 3: installation formwork for placing, the upper surface of the formwork for placing and the upper surface of blocking partition wall 1 are flush；It pours
The equal length of the length of building mould and the blocking partition wall 1.
Step 4: pouring mouth casting concrete from formwork for placing, concrete combines together to be formed with ground beam support construction 9
Armored concrete ground beam 10(armored concrete ground beam may be simply referred to as ground beam), concrete and rebar mesh sheet, tension rib combine together
Concrete slab 12 is formed, armored concrete ground beam 10 and concrete slab 12 collectively form compound L-type concrete slab 2, and compound L-type is mixed
Concrete board 2 may be simply referred to as L wall.Compound L-type concrete slab 2 combines together to form unit combined wall 3 with blocking partition wall 1.
The lateral surface retraction wall face of blocking partition wall of the armored concrete ground beam 10, medial surface are from blocking partition wall
The back side protrusion.In the present embodiment, 4 centimeters of the wall face of the lateral surface of ground beam 10 retraction blocking partition wall 1, medial surface are from unit
Protrude 5 centimeters in the back side for changing partition wall 1.Ground beam 10 not only can be used as the supporting table in 1 handling process of blocking partition wall, but also can guarantee
The globality of blocking partition wall 1.
The lateral surface of armored concrete ground beam 10 is equipped with the brick bat of 4mm thickness.
When casting concrete, built-in fitting can be disposed at 12 back side of concrete slab in the 12 pre-buried lifting lug 13 in top of concrete slab
15, i.e., after compound L-type concrete slab completes, the top of unit combined wall 3 is embedded with lifting lug 13, the back side be mounted with it is pre-
Embedded part 15.In the present embodiment, the top of unit combined wall 3 is pre-buried there are two lifting lug, and the plating of 150mm*150mm can be selected in lifting lug
Zinc steel plate offers lifting hole(eyelet) on the lifting lug.
In the present embodiment, the top two sides of the formwork for placing used are respectively arranged with a card slot, pour in this way when to this
Placing concrete in template, after concrete slurry solidification, the two sides at 2 top of compound L-type concrete slab of formation will distinguish shape
At a card slot 14.The mouth that pours of formwork for placing pours mouth for 45 °.
Step 5: opening up groove (being not drawn into figure) in the upper surface of unit combined wall 3, water-stop glue is installed in groove
Item, article rubber water stop, which meets water, can generate expansion, be used for external wall waterproof.In the present embodiment, the longitudinal section of the groove is in inverted trapezoidal, only
The shape of glue item and the shape of groove match.
Step reinforces the wall body structure of the blocking partition wall of historical building according to the method described above, can be avoided rear
It is continuous to shift, lift, being assembled into the processes such as whole face wall its wall is damaged.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all in essence of the invention
Within mind and principle, any modification, equivalent substitution, improvement and etc. done be should be included within the scope of the present invention.
