Description

Technical Field

[0001] The invention belongs to the technical field of blue brick masonry, and in particular relates to a blue brick wall brick seam processing process. Background Art

[0002] As a high-quality traditional building material, the history of blue bricks can be traced back to the end of the slave society and the beginning of the feudal society. Various varieties of blue bricks have been found in the architectural sites of the Warring States Period, such as strip bricks, square bricks and railing bricks. These blue bricks were mainly used for paving and wall construction. In the Qin Dynasty, the use of blue bricks increased significantly. Qin Shihuang used a large number of blue bricks in projects such as building the capital, palaces, roads and tombs. Blue bricks are widely used in the wall construction of ancient buildings because of their hardness and strength after firing. In the Ming and Qing Dynasties, blue brick masonry technology ushered in a golden age. Various brick wall masonry techniques were relatively mature and the blue brick art was greatly developed.

[0003] In the Chinese patent with publication number CN113047646B, a brick joint caulking and grouting device and construction method are mentioned, the device includes a caulking and grouting trolley that can move forward and backward on the surface of the masonry structure and a storage hopper for storing mortar filled in the brick joints, and a butt joint is arranged at the bottom of the storage hopper; the caulking and grouting trolley includes a frame, a mortar delivery channel, a connecting joint, a walking mechanism and a grouting device, two mortar extrusion strips are arranged on the outside of the frame, the grouting device includes two front and rear grouting mechanisms, and the grouting mechanism includes a connecting frame and a groove pressing wheel; the construction method is to use the brick joint caulking and grouting device to caulk or grout the processed brick joints. The present invention has reasonable design, simple operation, high construction efficiency and good use effect, uses a movable brick joint caulking and grouting device to caulk or grout the brick joints, can automatically send the filling mortar into the processed brick joints, and can compact and groove the filling mortar sent into the brick joints, and can ensure the quality of caulking and grouting.

[0004] However, the above technical solution compacts and grooves the filling mortar sent into the brick joints, and can ensure the quality of filling and grouting. Although the above device can improve the quality of brick joint filling, the filling effect of the brick joints is relatively simple, and the accuracy and aesthetics of the internal filling are poor, resulting in a relatively general filling effect of the brick joints, so the staff needs to improve it. Summary of the invention

[0005] The object of the present invention is to provide a process for treating brick joints in a blue brick wall to solve the problems raised in the above-mentioned background technology.

[0006] To achieve the above object, the present invention provides the following technical solutions:

[0007] A process for processing brick joints in a blue brick wall comprises the following steps:

[0008] S1. Clean the original aerated blocks and main structure masonry walls, and use special interface mortar to fully apply and scrape the walls;

[0009] S2. Mixing of waterproof mortar: Use a mortar mixer or a portable electric drill with mixing teeth for on-site mixing to ensure uniform mixing;

[0010] S3, waterproof mortar plastering: First, the wall surface needs to be inspected to ensure the flatness of the large surface. The control lines of the ash cakes and the edge control lines of the door and window openings are drawn using an infrared level. The large surface ash cakes should be no less than two rows with a spacing of ≤1800mm. Corner guards need to be added at the external corners before plastering. The corner guards are 2000mm high and 50mm wide on both sides. Then, cement mortar plastering of the wall is carried out;

[0011] S4. Watering of green bricks: Clay bricks must be soaked in water one day before laying, with water penetrating 15mm on all sides of the bricks and a moisture content of 10% to 15%;

[0012] S5, Full-length tie bars: Use 4mm diameter steel bars to tie the reserved tie bars firmly, and arrange the steel bars along the full length of the wall;

[0013] S6. Slotting of blue bricks: Use a slotting machine to slot the blue bricks connected to the tie bars. The slot width is 30mm and the depth is 10mm.

[0014] S7. Blue brick masonry: When laying the first layer of bricks on the exterior wall, the two gables are laid with diagonal bricks, and the front and rear longitudinal walls are laid with strip bricks. Corners should be rolled before bricklaying. Do not roll more than five layers of corners each time. The newly rolled large corners should be hung and supported in time, and any deviation should be repaired in time.

[0015] S8. Eaves, windows, and screen wall brickwork: Eaves, windows, and screen walls should be built layer by layer according to the brickwork style. Grooves should be cut and tied with copper wire. The inner cavity of the eaves should be filled with blue bricks and protected immediately after construction.

[0016] S9. Eaves brick and seam construction: locate the eaves and seam corners in advance. The eaves brick carving and the wall advance and retreat dimensions shall be based on the drawings. After the masonry is completed layer by layer, seam construction shall be carried out. The seam masonry is built from the eaves to the top in sequence. The inner lining of the diamond wall is built with blue bricks and tied. The seam bricks need to be grooved up and down and tied with copper wire.

[0017] S10. Brick wall grouting: The mortar joints of whitewashed walls and silk-seam walls should be marked with a special tool "duckbill". The brick wall mortar should be grouted immediately after the initial setting. The grouting depth should be consistent and the appearance should be natural and beautiful. After the grouting is completed, it should be cleaned with a steel brush and wool cloth. The blue brick wall surface needs to be artistically grouted twice;

[0018] S11. Cleaning work: When a wall is completed, all defective brick surfaces (holes, sand holes, missing edges and corners) should be repaired with mortar. The mortar is made by mixing brick powder with either cement or adhesive, and must be the same color as the mud bricks.

[0019] Preferably, in step S1, after solidification, cement mortar is used to perform 8 mm post-beating and roughening to ensure that the thickness of the mortar is uniform, and the spacing between the mortars and the order of each layer of mortars remain consistent.

[0020] Preferably, in step S2, the stirring time is extended by 2 to 3 minutes compared with ordinary mortar. It is pre-mixed for 2 minutes, stopped for 2 minutes, and then stirred for a second time for 2 minutes to ensure full mixing. The water-cement ratio of the first layer is 0.55 to 0.60, and the water-cement ratio of the second layer is 0.40 to 0.50. The stirred waterproof mortar should be used up within one hour.

[0021] Preferably, in step S3, a stepped slope should be used when leaving construction joints, the joints should be tightly overlapped, the positive and negative corners should be made into arc shapes, the positive angle diameter is 10 mm, and the negative angle diameter is 50 mm. After the waterproof mortar solidifies, it is naturally cured, and the curing temperature is not lower than 5°C.

[0022] Preferably, in step S4, dry bricks shall not be used on the wall during normal temperature construction, and bricks with a saturated moisture content shall not be used to build walls during the rainy season; the mortar consistency must be appropriately increased in winter.

[0023] Compared with the prior art, the present invention has the following beneficial effects:

[0024] (1) The use of special interface mortar, cement mortar primer and waterproof mortar effectively enhances the bonding strength and structural stability of the wall, improves the integrity and durability of the wall, especially the binding of full-length tie steel bars and the mortar filling after the blue brick grooves are opened, which further strengthens the connection between the blue brick and the wall and prevents the wall from cracking and deformation.

[0025] (2) The mixing and plastering process of the waterproof mortar is carried out strictly in accordance with the proportion and time requirements, ensuring the continuity and density of the waterproof layer, effectively preventing rainwater penetration, protecting the wall structure, and extending the service life of the building.

[0026] (3) The soaking treatment of blue bricks and the two-time artistic grouting process make the brick joints uniform and beautiful, and the wall surface neat and delicate. The spot cleaning step also carefully repairs the defective brick surface, ensuring the overall beauty and coordination of the blue brick wall and enhancing the artistic value of the building.

[0027] (4) The use of tools such as infrared levels, counting rods, and special-sized seam clamps during the masonry process, as well as strict construction process requirements such as double-sided hanging lines and layer-by-layer masonry, ensures the accuracy and consistency of blue brick masonry, reduces construction errors, and improves construction quality.

[0028] (5) With regard to the brickwork techniques involving eaves, windows, screen walls, etc., the integrity and historical features of these cultural heritages have been effectively protected through meticulous bricklaying and tie-in treatment, allowing the ancient buildings to be inherited and continued.

[0029] (6) The treatment process of blue brick walls also takes into account the influence of different seasons and climatic conditions. For example, measures such as increasing the mortar consistency and soaking blue bricks in water in winter enhance the wall's ability to adapt to the environment and reduce problems such as wall cracking caused by temperature changes. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] Figure 1 It is a process flow chart of the present invention. DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] Embodiment 1:

[0033] See also Figure 1 As shown, a process for processing brick seams in a blue brick wall comprises the following steps:

[0034] S1. Clean the original aerated blocks and main structure masonry walls, apply special interface mortar to the wall, and after solidification, use cement mortar to make 8mm post-mortar sweeping. Ensure that the mortar thickness is uniform, and the mortar spacing and mortar order of each layer are kept consistent;

[0035] S2. Mixing of waterproof mortar: Use a mortar mixer or a portable electric drill with stirring teeth to mix on site to ensure uniform mixing. The mixing time is 2 to 3 minutes longer than that of ordinary mortar. Pre-mix for 2 minutes, let stand for 2 minutes, and then stir for 2 minutes to fully mix. The water-cement ratio of the first layer is 0.55 to 0.60, and the water-cement ratio of the second layer is 0.40 to 0.50. The mixed waterproof mortar should be used up within one hour;

[0036] S3. Waterproof mortar plastering: First, the wall surface must be inspected to ensure the flatness of the large surface. Use an infrared level to draw the ash cake control line and the door and window opening edge control line. The large surface ash cake should be no less than two rows, with a spacing of ≤1800mm. Corner guards need to be added at the external corners before plastering. The corner guards are 2000mm high and 50mm wide on both sides. Then, cement mortar plastering of the wall is carried out. When leaving construction joints, a stepped slope should be used, and the joints should be tightly overlapped. The internal and external corners should be made into arcs, with a diameter of 10mm for the external corner and 50mm for the internal corner. After the waterproof mortar solidifies, it should be naturally cured at a temperature not lower than 5°C;

[0037] S4. Watering of green bricks: Clay bricks must be soaked in water one day before laying, with water penetrating 15mm on all sides of the bricks and a moisture content of 10% to 15%. Dry bricks must not be used on the wall during normal temperature construction, and bricks with a saturated moisture content must not be used to build walls during the rainy season. If watering is difficult in winter, the mortar consistency must be appropriately increased;

[0038] S5, Full-length tie bars: Use 4mm diameter steel bars to tie the reserved tie bars firmly, and arrange the steel bars along the full length of the wall;

[0039] S6. Slotting of blue bricks: Use a slotting tool to slot the blue bricks connected to the tie bars. The slot width is 30mm and the depth is 10mm. Fill the slots with mortar during masonry.

[0040] S7. Blue brick masonry: When the first layer of bricks for the exterior wall is laid, the two gables are arranged with diagonal bricks, and the front and rear longitudinal walls are arranged with strip bricks. Before bricklaying, the corners should be rounded first. No more than five layers of corners should be rounded each time. The newly-rounded large corners should be suspended and leaned in time, and any deviations should be repaired in time. When the corners are rounded, the brick layers and elevations of the skin number rod should be carefully compared, and the size of the mortar joints should be controlled to make the horizontal mortar joints uniform. After the large corners are rounded, check again. Only when the flatness and verticality meet the requirements can the line be hung for wall construction. When laying bricks, hold the bricks in one hand and use the trowel with mortar to apply mortar strips on the lower outer edges of the bricks with the other hand. You can also apply mortar strips on the outer edges of the already laid brick layers. After the bricks are laid, use the trowel to scrape off the remaining mortar squeezed out of the bricks. You don't need to mark the joints temporarily. Wait until the masonry mortar and white lime are initially solidified before grouting. When laying bricks, you must hang the line on both sides. If several people use a through line for a long wall, several branch points should be set in the middle, and the small line should be tightened. Each layer of bricks must be checked for leveling to ensure that the horizontal joints are uniform, straight and smooth, the horizontal mortar joints and vertical mortar joints are of the same size, and the specific brick joint size and retreat requirements meet the brick joint requirements. When laying blue bricks, special size joint cards must be used to control the size of brick joints. To ensure that there is no loosening of joints, when the bricks are laid one step higher, two vertical lines should be drawn at the position of the bricks at a horizontal spacing of about 2m to control the loosening of joints in sections. To ensure that there is no error in the elevation of each brick on the entire gable, after the wall is plastered, a through line is drawn at the elevation of each meter at the four corners of the gable to control the overall elevation of the blue bricks of the building to remain consistent. During the operation, self-inspection must be carried out seriously. If there is any deviation, it should be corrected at any time. It is strictly forbidden to smash the wall afterwards. The height of the masonry should not exceed 1.2 meters every day. After the masonry reaches 1.2 meters, grouting, dotting, flooding, ploughing and cleaning processes must be carried out;

[0041] S8. Eaves, windows, and screen wall brickwork: Eaves, windows, and screen walls should be built layer by layer according to the brickwork style. Grooves should be cut and tied with copper wire. The inner cavity of the eaves should be filled with blue bricks and protected immediately after construction.

[0042] S9. Eaves brick and seam construction: locate the eaves and seam corners in advance. The eaves brick carving and the wall advance and retreat dimensions shall be based on the drawings. After the masonry is completed layer by layer, seam construction shall be carried out. The seam masonry is built from the eaves to the top in sequence. The inner lining of the diamond wall is built with blue bricks and tied. The seam bricks need to be grooved up and down and tied with copper wire.

[0043] S10. Brick wall grouting: The mortar joints of whitewashed walls and silk-seam walls should be marked with a special tool "duckbill". The brick wall mortar should be grouted immediately after the initial setting. The grouting depth should be consistent and the appearance should be natural and beautiful. After the grouting is completed, it should be cleaned with a steel brush and wool cloth. The blue brick wall surface needs to be artistically grouted twice;

[0044] S11. Cleaning work: When a wall is completed, all defective brick surfaces (holes, sand holes, missing edges and corners) should be repaired with mortar. The mortar is made by mixing brick powder with either cement or adhesive, and must be the same color as the mud bricks.

[0045] Quality inspection points:

[0046] 1. For the selected wall tiles, the flatness of the brick surface is allowed to be within 1mm, and the length of the brick surface is allowed to be within 1mm. It is strictly forbidden to put bricks with missing corners or uneven surfaces on the wall.

[0047] 2. The allowable deviation of blue brick masonry quality is as follows:

[0048] (1) Axis deviation: plus or minus 5 mm (check with a ruler).

[0049] (2) Wall verticality:

[0050] (a) Below 5m or each floor height: plus or minus 3mm;

[0051] (b) Below 10m: ±6mm;

[0052] (c) Above 10m: plus or minus 10mm (checked by plumb line, infrared ray and ruler).

[0053] (3) Wall flatness: plus or minus 3 mm (checked with a 2m horizontal, vertical, inclined tower and wedge-shaped feeler gauge).

[0054] (4) Straightness of horizontal mortar joints:

[0055] (a) Within 2m: plus or minus 2mm (pull a 2m wire and measure with a ruler);

[0056] (b) Beyond 2 m: plus or minus 3 mm (pull a 5 m wire (if less than 5 m, pull a continuous wire) and measure with a ruler).

[0057] (5) Thickness of mortar joints in silk joint walls (3 to 4 mm thick): plus or minus 1 m (randomly check the largest mortar joint and measure with a ruler).

[0058] (6) Silk seam wall with loose seams:

[0059] (a) 2m or less: 5mm;

[0060] (b) Below 5m or each floor height: 10mm (check with hanging line and ruler (based on the skin bricks of the bottom layer)).

[0061] 3. The size of the blue brick joints and the retreat after plastering shall be based on the sealing sample size. The brick joints shall be polished twice to ensure that the retreat is uniform and the surface is free of pollution.

[0062] 4. The blue bricks at the door and window openings are of the size of 1-inch bricks. The vertical edges of the brick walls must be kept vertical, and the edges of the skirting stones must be straightened in place, with the inner recessed dimensions consistent with those of the blue bricks.

[0063] 5. During the construction of the wall skirt stone, in order to ensure the wall pressing the ground effect, the bottom of the first layer of wall skirt needs to be temporarily filled with mortar, and then stuffed into the wall skirt stone during the construction of the floor stone.

[0064] 6. The layout of the stone wall skirt must be consistent with the layout drawing, and attention must be paid to the protection of the finished product during construction.

[0065] 7. The elevations of windows, eaves, seams, eaves exterior finishes, upper and lower edges of door and window shutters, etc. must be consistent with the elevations in the drawings while meeting the requirements for whole brick laying.

[0066] 8. Bricklaying should follow the line on the top and the edge on the bottom, that is, the upper edge of the brick should be based on the horizontal line, and the lower edge should be based on the upper edge of the bottom brick.

[0067] 9. When laying bricks, the appearance of the bricks should be properly checked before laying. Bricks that are not square cannot be used at the corners of the wall, and bricks with damaged surfaces or uneven edges cannot be used for the outer skin. When the wall height is below the eye level (called low-head work), the side of the brick with the better edge should be placed upwards. When it exceeds the eye level (called high-head work), the side of the brick with the better edge should be placed downwards.
