EXAMPLE III
The construction method for repairing the wall of the historical building provided by the embodiment is further described below with reference to fig. 1 to 10, and the first embodiment and the second embodiment. The construction method comprises the following steps:
firstly, dividing a historical building wall 1 into a plurality of unit modules 2, and determining block boundary lines 3 between the unit modules 2. The description of fig. 1 in embodiment two may be specifically referred to.
And secondly, reinforcing the door and window positions of the unit modules 2, reinforcing the unit modules 2 on two sides of the block boundary line 3 along the block boundary line 3, and installing a hoisting frame 20 and a reinforcing bent frame 30. And reinforcing the unit modules 2 of the historical building wall body 1 from bottom to top, and finishing the reinforcement of all the unit modules 2. Reinforcing the positions of doors and windows of the unit modules 2, namely arranging a support frame 40 in an inner frame of the doors and the windows; and reinforcing the unit modules 2 on two sides of the block boundary line 3 along the block boundary line 3, namely correspondingly arranging reinforcing steel plates 10 on the inner and outer wall surfaces of the same unit module along the block boundary line, and fixing the reinforcing steel plates by using split bolts 11. The specific structures of the support frame 40, the reinforcing steel plate 10, the hoisting frame 20, and the reinforcing bent 30 can refer to the first embodiment, and the specific reinforcing method can refer to the second embodiment, which is not described herein again.
And thirdly, cutting the historical building wall 1 along the block boundary line 3, and hoisting the cut unit modules 2 to a repair site. The cutting of the unit modules is performed from top to bottom in sequence. As an example, cutting is performed using a chain saw cutting machine, a diamond chain of which is sheathed at a block boundary line 3 of a wall body and forms a closed cutting loop line by a guide wheel, and block is rapidly cut along the block boundary line 3. After cutting, the lifting lugs 23 of the lifting frame 20 are lifted by using a lifting machine, the unit modules 2 are lifted, and can be transported to a repair site through a transport vehicle, and then the unit modules 2 are placed at appropriate positions by using the lifting machine.
Fourthly, processing and repairing the unit module 2 in a repairing field; meanwhile, the main structure of the original historical building is reformed, a structural steel beam 7 and a structural steel column 8 are newly added according to the blocking condition of the unit modules 2, and a bracket 9 is arranged on the structural steel column.
The method for processing and repairing the unit module 2 in the repair site specifically comprises the following steps: dismantling the reinforcing bent 30 and the hoisting frame 20 on the inner wall side of the unit module 2; the thickness H of the wall body in the region of the non-reinforced steel plate 10 of the inner wall of the unit module 2 is chiseled1Then arranging a reinforcing mesh 4 in the chiseled-off area, and pouring concrete to form a concrete lining wall 5; dismantling the reinforcing steel plates 10 at the partitioned boundary lines 3 of the unit modules 2, chiseling the thickness H2, arranging reinforcing meshes 4 in the chiseling areas, and pouring concrete to form concrete frames 6, wherein the concrete frames 6 are connected with the concrete lining wall 5 into a whole; repairing and pointing the outer wall of the unit module 2; after the pointing process, a soft cushion layer such as a rubber sheet is attached to the repaired exterior wall surface, and the unit module 2 is placed on a transportation custom jig. For example, H1Is 3 bricks in thickness, H2The thickness of the bricks is 2, the chiseled bricks are reserved for later use, and the poured concrete frame 6 is flush with the surface of the concrete lining wall 5. Before concrete frame 6 pours with concrete interior wall 5, can pre-buried connecting piece, install the sign indicating number piece on the connecting piece, leave as later stage erection equipment and use. Preferably, alongAnd a circle of water stopping grooves are formed around the concrete frame 6 and used for arranging water stopping expansion strips.
The outer wall repairing steps of the unit module 2 are as follows: slotting → repairing the brick surface, replacing the brick → adding the brick → hooking the bottom seam. According to different damage degrees of the brick surface, the repairing process flow can be adjusted:
(a) and for the original brick surface, a better brick is reserved, and only the seam is cleaned and repaired.
(b) And adopting brick powder to repair the brick surface with the damage depth of more than 5mm and less than 20 mm.
(c) And for the brick surface with the damage depth larger than 20mm, the whole brick of the on-site old brick is inlaid.
And fifthly, hoisting the repaired wall body to the original position, placing the wall body on the bracket of the structural steel column, and splicing the unit modules 2 with the unit modules 2. The hoisting and resetting of the unit modules are sequentially carried out from bottom to top. Because the historical building wall body 1 is after the cutting, the partial fragment of brick of joint cutting department is cut open, need take out the back and build the old brick again. The splicing processing method between the unit modules 2 and the unit modules 2 comprises the following steps: after the unit modules 2 are hoisted in place, water stopping expansion strips are arranged in the water stopping grooves along the periphery of the concrete frame 6; adjusting the position, the flatness and the verticality of the unit module 2, and grouting in the gap of the splicing seam to form an integral outer wall; the method comprises the steps of adopting a drawing and building process, drawing out non-whole bricks on the outer wall of the unit module 2, building and recovering the outer wall by using reserved old bricks, performing color matching treatment on the whole outer wall to enable the whole effect color of the outer wall to be uniform, then pointing out seams, and finally performing water adding treatment on the whole outer wall to finish the repairing of the outer wall.
According to the construction method for repairing the historical building wall 1, the historical building wall 1 is integrally cut into blocks and hoisted, so that the integrity of the old building wall 1 is protected, and the original masonry process is kept; in the cutting and hoisting process, reinforcing measures such as reinforcing steel plates 10, hoisting frames 20, reinforcing bent frames 30 and the like are adopted, so that the unit modules 2 can be effectively protected; and the assembly type installation in place is adopted in the later period, so that the method is simple, convenient and quick, and the construction period is shortened.
The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.
The above-mentioned embodiments only express several embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention. Therefore, the protection scope of the present patent shall be subject to the appended claims.
