Description

Technical Field

[0001] This invention relates to the field of ancient building restoration, specifically to a construction method for in-situ paving of old and broken gold brick flooring after restoration of ancient buildings. Background Technology

[0002] When the brick and stone floors of ancient buildings become broken and aged, they are usually demolished and renovated to restore their original appearance. The newly laid brick and stone floors are mostly relaid using antique-style bricks and stones. In some projects, selected old bricks and stones that meet the requirements for reuse may be repaired and relaid. Using old bricks and stones in specific areas requires very high standards for the overall construction. Firstly, the selection and repair of the old bricks and stones must be extremely rigorous, especially regarding the degree of damage, the size and depth of cracks, and the number of cracks. Repair materials and methods must also be carefully selected based on the material and crack condition of the bricks and stones. Furthermore, the new and old bricks and stones must be seamlessly integrated in terms of specifications, color, and quality. Therefore, the requirements for the antique effect of the new bricks and stones are also very high.

[0003] The above-mentioned approaches have significant shortcomings in both the restoration of ancient buildings and the construction of imitation ancient buildings. The former involves complete demolition and renovation, which, while achieving the effect of restoring the old to its original state, fails to fully utilize the old bricks and stones. This is especially true in the restoration of ancient buildings, where the use of entirely new imitation antique bricks and stones instead of fully utilizing the original old bricks and stones results in a loss of rustic charm. The latter approach, which involves selectively selecting and combining imitation antique bricks and stones for paving, raises the construction requirements and increases the difficulty, making it difficult to effectively guarantee the restoration of the original appearance. Summary of the Invention

[0004] To address the technical problems existing in the prior art, this invention provides a construction method for the in-situ paving of old and broken gold brick floors in ancient buildings after restoration, realizing the complete restoration and reuse of broken gold bricks in old floors of ancient buildings, and ensuring that all paving is done in situ, thus restoring the original appearance of the ancient buildings.

[0005] To achieve the above objectives, the technical solution of the present invention is as follows:

[0006] A method for resurfacing old, broken brick floors in ancient buildings after restoration includes the following steps:

[0007] Step 1: Fabricate a steel frame according to the dimensions and specifications of the four ancient bricks;

[0008] Step 2: Lay the wire mesh and weld it to the steel frame;

[0009] Step 3: Lay cement mortar on the wire mesh;

[0010] Step 4: After the cement mortar reaches 80% strength, lay a sand cushion layer on top to form a support.

[0011] Step 5: Repeat the above steps to make multiple sets of brackets;

[0012] Step six: Number the ancient bricks according to the laying sequence requirements, and excavate, clean, and assemble them in groups of four adjacent bricks, and correct their flatness.

[0013] Step 7: Use construction-specific adhesive mixed with bonding powder to grout and repair the joints and cracks;

[0014] Step 8: After the adhesive powder has solidified to the required strength, use a polishing tool to smooth and polish the surface of the ancient brick.

[0015] Step 9: Remove the restored ancient brick from the bracket and clean the loose sand from the bottom;

[0016] Step 10: Remeasure the length and width of each group of ancient bricks, and cut and trim the edges of each group of ancient bricks after restoration.

[0017] Step 11: Make cross-shaped joints for each group of ancient bricks;

[0018] Step 12: Lay out the restored ancient bricks according to their numbers.

[0019] As a preferred technical solution, in step one, angle steel is used to process and manufacture the steel frame according to the size of the ancient gold bricks. When processing the dimensions, the increase in cross-sectional dimensions caused by paving joints and crack repairs is taken into account.

[0020] As a preferred technical solution, in step three, a 1:2 cement mortar is used, and the thickness of the cement mortar is 20mm.

[0021] As a preferred technical solution, in step six, the cracks and surfaces of the excavated ancient brick fragments are cleaned with a brush, and they are immediately assembled in situ on the bracket. A rubber mallet is used to lay them down during assembly, and the surface is pressed flat. Each set of ancient bricks is protected after assembly.

[0022] As a preferred technical solution, in step seven, the crack grouting is carried out in 2-3 times. The next grouting is carried out only after the previous adhesive powder has completely penetrated. The adhesive powder is always lower than the brick surface.

[0023] As a preferred technical solution, in step eleven, a cross-shaped joint with a width of 2mm is made for each group of ancient bricks, and the joint is made straight and filled with putty along the joint until it is fully flat.

[0024] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0025] (1) The present invention provides a construction method for the original paving of old and broken gold brick flooring of ancient buildings after repair. The original broken gold bricks are used to re-pave in the original location, which completely preserves the original appearance of the ancient buildings. The gold bricks are re-paved in the original location after repair, which extends the service life of the gold bricks.

[0026] (2) The combined bracket used in the construction method of the old and broken gold brick floor repair of ancient buildings in this invention provides a good support and limit for the repair of ancient gold bricks. The use of angle steel effectively ensures the cross-sectional size of the ancient gold bricks during the construction of adhesive powder filling, and prevents the broken gaps of the gold bricks from expanding disorderly without side limit. The wire mesh and cement slurry provide a convenient and reliable substrate, and the sand cushion layer effectively adjusts the surface flatness of the ancient gold bricks.

[0027] (3) In the construction method of the present invention for the original paving of the old and broken gold brick floor after the repair of the ancient building, the bracket can be reused. In special cases such as severe cracking of the ancient gold brick, in order to further improve the subsequent paving quality of the ancient gold brick, the angle steel frame and the other subfloor can be separated, and the subfloor can be paved together with the repaired ancient gold brick.

[0032] The technical solution of the present invention will be further described below with reference to specific embodiments:

[0033] A method for resurfacing old, broken brick floors in ancient buildings after restoration includes the following steps:

[0034] Step 1, as follows Figure 1 As shown, L50 angle steel is used to process and manufacture the steel frame 1 according to the size specifications of four ancient bricks 5. When processing the dimensions, the impact of the increase in cross-sectional dimensions caused by factors such as paving joints and crack repair should be taken into account.

[0035] Step two, after the steel frame 1 is processed, as follows: Figure 2 As shown, a 5mm*5mm steel wire mesh 2 is laid and welded to the steel frame 1;

[0036] Step 3: Lay a 20mm thick 1:2 cement mortar 3 on the wire mesh 2; the cement mortar 3 should be flat to meet the construction requirements.

[0037] Step 4: After the cement mortar 3 reaches 80% strength, lay a 25mm thick sand cushion layer 4 on top. The sand cushion layer 4 should be flat. The steel frame 1, wire mesh 2, cement mortar 3 and sand cushion layer 4 are combined to form a bracket.

[0038] Step 5: Repeat the above steps to make multiple sets of brackets;

[0039] Step 6: Number the ancient bricks 5 according to the laying sequence requirements, and excavate them in groups of four adjacent bricks. Use a brush to clean the cracks and surface of the excavated ancient brick 5 fragments, and immediately assemble them in place on the bracket. When assembling, the angles must be accurate and the lines must be straight. Use a rubber mallet to lay them and flatten the surface. After each group of ancient bricks 5 is assembled, protect the product.

[0040] Step 7: Use building-specific adhesive mixed with bonding powder to grout and repair the joints and cracks. Specifically, the grouting of the cracks is carried out in 2-3 times. The next grouting is carried out only after the bonding powder has completely penetrated in the previous time. The bonding powder should not be higher than the brick surface.

[0041] Step 8: After the adhesive powder solidifies to the required strength, it has a certain hardness and gloss, and its color is different from that of the surface of the ancient brick 5. It is necessary to use a polishing tool to smooth and polish the surface of the ancient brick 5.

[0042] Step 9: Remove the restored ancient brick 5 from the bracket and clean the loose sand from the bottom;

[0043] Step 10: Remeasure the length and width of each group of ancient bricks 5, and cut and trim the edges of each group of ancient bricks 5 after restoration.

[0044] Step 11: In order to make a white sealing line appear between the ancient bricks 5, make a cross joint for each group of ancient bricks 5. Specifically, the joint width is 2mm, the joint must be straight, and putty is used to fill the joint until it is completely flat.

[0045] Step 12, as follows Figure 3 As shown, the ancient bricks in each group were repaired and laid according to their numbers.

[0046] This embodiment is merely a further explanation of the present invention and is not intended to limit the present invention. Those skilled in the art can make non-inventive modifications to this embodiment as needed after reading this specification, but such modifications are protected by patent law as long as they are within the scope of the claims of the present invention.
