Description

Technical Field

[0001] The invention relates to the technical field of building construction, and more specifically to an autoclaved aerated concrete block and a method for building a filling wall thereof. Background Art

[0002] At present, the filling walls built with autoclaved aerated concrete blocks in housing construction projects generally adopt the "three-in-one" masonry method, that is, one brick, one shovel of mortar, and one squeeze (abbreviated as "three-in-one"), and the squeezed mortar is scraped off at will.

[0003] The "three-in-one" bricklaying method will cause wall pollution and a lot of dust on the ground. In addition, since it is usually operated by one person, the operation process requires taking bricks, shoveling dust, stirring dust, turning around, and bending over. The labor intensity is high and it takes time, which affects the efficiency of masonry. In addition, the control of the mortar joints, mortar fullness, wall verticality, and wall flatness is mainly manual, which requires high technical literacy of personnel and is difficult to control. In addition, there is a lot of dust on the ground during construction, which can easily cause wall pollution. In addition, each layer of bricks in the wall has a mortar joint, which causes a large amount of wall settlement, a long interval between the top inclined bricks, and in the later stage, due to the settlement of the wall, it is very easy to cause a through seam at the junction with the main structure, and the construction quality is difficult to be effectively guaranteed.

[0004] Therefore, a construction plan that can ensure the quality of wall construction is urgently needed. Summary of the invention

[0005] In view of the above problems, the purpose of the present invention is to provide an autoclaved aerated concrete block and a filling wall construction method thereof to solve the problems of labor-intensive and difficult quality assurance in existing filling wall construction schemes.

[0006] The autoclaved aerated concrete blocks provided by the present invention include six kinds of special-shaped autoclaved aerated blocks assembled in a reinforced concrete structure by mutually engaging grooves and protrusions arranged on the top, bottom and left and right side walls; including:

[0007] The side bricks on both sides of the bottom are used as the first skin bricks on both sides of the bottom of the filling wall; the bottom of the side bricks on both sides of the bottom are flat, a groove is set at the center of the top, the left and right sides are flat on one side adjacent to the reinforced concrete structure, and a protrusion or a groove is set at the midpoint of the other side;

[0008] The bottom middle brick is used as the first brick to fill the middle position of the bottom of the wall; the bottom middle brick has a flat bottom, a groove is provided at the center of the top, and a bulge and a groove are provided at the midpoint of the left and right sides respectively;

[0009] The side bricks above the first course are used as the side bricks on both sides above the first course of the infill wall; a protrusion is provided at the center of the bottom of the side bricks above the first course, and a groove is provided at the center of the top. One side of the left and right side faces adjacent to the reinforced concrete structure is flat, and a protrusion or a groove is provided at the position of the vertical bisector of the other side face.

[0010] The intermediate bricks above the first course are used as the bricks at the intermediate position above the first course of the infill wall; a protrusion is provided at the center of the bottom of the intermediate bricks above the first course, and a groove is provided at the center of the top. A protrusion and a groove are respectively provided at the positions of the vertical bisectors of the left and right side faces.

[0011] In addition, an optional solution is that the depth of the groove is 1 cm, and the width is 1 / 5 of the width of the special autoclaved aerated concrete block; the height of the protrusion is: the depth of the groove + the mortar joint thickness.

[0012] In addition, an optional solution is that the heights of the bottom side bricks and the bottom intermediate bricks are the same; and the length of the protrusion provided on the bottom side bricks and the bottom intermediate bricks is: the height of the bottom side bricks - the depth of the groove.

[0013] In addition, an optional solution is that the heights of the side bricks above the first course and the intermediate bricks above the first course are the same; and,

[0014] The length of the protrusion provided at the bottom of the side bricks above the first course and the intermediate bricks above the first course is: the length of the side bricks above the first course + the depth of the groove + the mortar joint thickness;

[0015] The length of the protrusion provided on the side walls of the side bricks above the first course and the intermediate bricks above the first course is: the height of the side bricks above the first course + the mortar joint thickness.

[0016] In addition, an optional solution is that the lengths of the bottom side bricks are different, and the lengths of the side bricks above the first course laid on the bottom side bricks are different from the lengths of the adjacent bottom side bricks above and below.

[0017] In addition, the present invention also provides a method for constructing an autoclaved aerated concrete block infill wall, using the autoclaved aerated concrete blocks as described above to construct the infill wall; the method includes:

[0018] Laying mortar on the base course of the reinforced concrete structure for leveling.

[0019] Laying the bottom side brick on one side, the bottom intermediate brick, and the bottom side brick on the other side according to a preset brick laying plan; wherein, mortar is filled in the gaps between the aerated blocks and the gaps between the aerated blocks and the main structure to form mortar joints.

The mortar joints can be determined during the production of the aerated blocks, and the mortar joints are fixed and unified during laying. The above six special-shaped autoclaved aerated blocks will be described in detail below.

[0047] Figure 2 Shows the first-course structure on one side at the bottom of the infill wall according to an embodiment of the present invention.

[0048] As Figure 2 shown, the first-course brick 1 on one side at the bottom of the infill wall serves as the bottom side brick of the infill wall. The bottom of its aerated block is flat, and there is a groove 7 in the upper part, centered. The depth of the groove 7 is 1 cm, and the width is 1 / 5 of the width of the aerated block; one side of the left and right sides of the aerated block is flat, and the other layer has a protrusion 8, centered. The size of the protrusion 8 is (1 cm + mortar joint) × (size of the aerated block - depth of the groove) × (slightly smaller than the width of the groove). The left side of the first-course brick 1 on one side at the bottom of the infill wall is adjacent to the left-side structure (of the reinforced concrete structure 9) or the construction column, and the gap therebetween is the mortar joint; the right-side protrusion is embedded into the left-side groove of the adjacent aerated block ( Figure 1 shown as the first-course brick 2 at the middle position at the bottom of the infill wall). The gap therebetween is the mortar joint. The upper groove is for the lower protrusion of the upper aerated block ( Figure 1 shown as the side brick 4 above the first-course and the middle brick 5 above the first-course) to be embedded. The gap therebetween is the mortar joint. If it is used for the exterior wall, its groove and protrusion are flush with the outside.

[0049] Figure 3 Shows the first-course brick structure at the middle position at the bottom of the infill wall according to an embodiment of the present invention.

[0050] As Figure 3 shown, the first-course brick 2 at the middle position at the bottom of the infill wall serves as the bottom middle brick laid at the middle position at the bottom of the infill wall. The bottom of its aerated block is flat, and there is a groove 7 in the upper part, centered. The depth of the groove 7 is 1 cm, and the width is 1 / 5 of the width of the aerated block; one side of the left and right sides of the aerated block has a protrusion 8, centered. The size of the protrusion 8 is (1 cm + mortar joint) × (size of the aerated block - depth of the groove) × (slightly smaller than the width of the groove), and there is also a groove 7 on the other side, centered. The depth of the groove 7 is 1 cm, and the width is 1 / 5 of the width of the aerated block.

[0051] The left-side groove of the first-course brick 2 at the middle position at the bottom of the infill wall is mutually embedded with the right-side protrusion of the left-side aerated block (i.e., the first-course brick 1 on one side at the bottom of the infill wall). The gap therebetween is the mortar joint. The right-side protrusion is embedded into the left-side groove of the aerated block adjacent to its right ( Figure 1 shown as the first-course brick 2 at the middle position at the bottom of the infill wall on the right side). The gap therebetween is the mortar joint. The upper groove is for the lower protrusion of the upper aerated block ( Figure 1 shown as the middle brick 5 above the first-course and the other side brick 6 above the first-course) to be embedded. The gap therebetween is the mortar joint. If it is used for the exterior wall, its groove and protrusion are flush with the outside.

[0052] Figure 4a And Figure 4b Shows the first-course brick structure on the other side at the bottom of the infill wall according to an embodiment of the present invention.

[0053] like Figure 4a and Figure 4b As shown, the first brick 3 on the other side of the bottom of the filling wall is used as the bottom edge brick of the filling wall ( Figure 1 The bottom of the aerated block is flat, with a groove 7 on the top, centered, 1 cm deep, and 1 / 5 of the width of the aerated block; the left and right sides of the aerated block are flat, and the other layer is also provided with a groove 7, centered, 1 cm deep, and 1 / 5 of the width of the aerated block. The right side of the first brick 3 on the other side of the bottom of the infill wall is adjacent to the right side structure or structural column of the reinforced concrete structure 9, and the gap between them is the mortar joint; the left groove and the adjacent aerated block ( Figure 1 The figure shows that the right side protrusions of the first brick 2) in the middle of the bottom of the filling wall are embedded with each other, and the gap between them is the mortar joint. The upper groove is the upper aerated block ( Figure 1 As shown in the figure, the lower protrusion of the other side brick 6) above the first skin is used for embedding, and the gap between them is the mortar joint. If used for external walls, the grooves and protrusions are flush with the outside.

[0054] Figure 4a and Figure 4b The difference is only that the length of the aerated block is different, so as to be applicable to different masonry length requirements. Of course, the first skin brick 3 on the other side of the bottom of the filling wall can also be directly cut to the required length on site.

[0055] Figure 5a and Figure 5b The figure shows a side brick structure above the first skin of a filling wall according to an embodiment of the present invention.

[0056] As shown in FIG5, the side bricks 4 on the side above the first skin of the filling wall are Figure 1 As the left side brick above the first skin of the filling wall, a protrusion 8 is set at the bottom of the aerated block, which is centered. The size of the protrusion 8 is (1cm+mortar joint)×(length of the aerated block+1cm+mortar joint)×(slightly smaller than the width of the groove); a groove 7 is set at the top, which is centered. The depth of the groove 7 is 1cm and the width is 1 / 5 of the width of the aerated block; one side of the left and right sides of the aerated block is flat, and there is a protrusion on the other side, which is centered. The size of the protrusion is (1cm+mortar joint)×(size of the aerated block+1cm+mortar joint-groove depth)×(slightly smaller than the width of the groove). The left side of the aerated block is adjacent to the left structure (reinforced concrete structure 9) or the structural column, and the gap between them is the mortar joint; the protrusion on the right is embedded in the adjacent aerated block ( Figure 1 The figure shows the groove on the left side of the middle brick 5) above the first skin of the wall, and the gap between them is the mortar joint. The upper groove is the upper aerated block ( Figure 1 The lower protrusions of the side bricks 4 and the middle bricks 5 above the first skin of the top filling wall are used for embedding, and the gaps between them are the mortar joints.Figure 1 Shown is the upper groove of the first course of bricks on one side at the bottom of the infill wall 1), and the gap therebetween is the mortar joint.

[0057] Figure 5a and Figure 5b The difference between them is only the length of the aerated blocks, so as to be applicable to different masonry length requirements. Of course, according to the on-site bricklaying situation, the side bricks 4 above the first course of the infill wall can also be directly cut to the required length on site.

[0058] If it is used for the exterior wall, its grooves and protrusions are flush with the outer side.

[0059] Figure 6 Shows the structure of the intermediate bricks above the first course of the infill wall according to an embodiment of the present invention.

[0060] As Figure 6 shown, the intermediate brick 5 above the first course of the infill wall serves as the intermediate position brick above the first course of the infill wall in Figure 1 . There is a protrusion at the bottom of its aerated block, centered, and the size of the protrusion is (1 cm + mortar joint) × (length of aerated block + 1 cm + mortar joint - groove depth) × (slightly smaller than the groove width); there is a groove at the upper part, centered, the groove depth is 1 cm, and the width is 1 / 5 of the width of the aerated block; on one side of the left and right sides of the aerated block, there is a protrusion, centered, and the size of the protrusion is (1 cm + mortar joint) × (size of aerated block + 1 cm + mortar joint - groove depth) × (slightly smaller than the groove width), and on the other side, there is a groove, centered, the groove depth is 1 cm, and the width is 1 / 5 of the width of the aerated block. The left groove of the aerated block is embedded with the right protrusion of the left aerated block, and the gap therebetween is the mortar joint; the right protrusion is embedded in the left groove of the adjacent aerated block on the right, and the gap therebetween is the mortar joint. The upper groove is for the lower protrusion of the upper aerated block to be embedded, and the gap therebetween is the mortar joint. The lower protrusion is embedded in the upper groove of its lower-layer aerated block, and the gap therebetween is the mortar joint. If it is used for the exterior wall, its grooves and protrusions are flush with the outer side.

[0061] Figure 7a and Figure 7b Shows the structure of another side brick above the first course of the infill wall according to an embodiment of the present invention.

[0062] As Figure 7a and Figure 7b shown, the other side brick 6 above the first course of the infill wall serves as the right side brick above the first course of the infill wall in Figure 1 . A protrusion 8 is provided at the bottom of its aerated block, centered, and the size of the protrusion 8 is (1 cm + mortar joint) × (length of aerated block + 1 cm + mortar joint) × (slightly smaller than the groove width); a groove 7 is provided at the upper part, centered, the depth of the groove 7 is 1 cm, and the width is 1 / 5 of the width of the aerated block; on one side of the left and right sides of the aerated block ( Figure 7a and Figure 7bThe right side (shown in [figure]) is flat, and there is a groove on the other side, centered, with a groove depth of 1 cm and a width of 1 / 5 of the width of the aerated concrete block. The right side of the aerated concrete block abuts against the right-side structure (of the reinforced concrete structure 9) or the structural column, and the gap between them is the mortar joint; the left-side groove and the adjacent aerated concrete block ( Figure 1 As shown in [figure], the middle brick 5 above the first course of the infill wall has a protrusion on the right side, and the gap between them is the mortar joint. The upper groove is for the upper aerated concrete block ( Figure 1 As shown in [figure], the lower protrusion of the other side brick 6 above the first course of the topmost infill wall is for embedding, and the gap between them is the mortar joint. The lower protrusion is embedded in the lower-layer aerated concrete block ( Figure 1 As shown in [figure], the upper grooves of the first-course bricks 2 in the middle position at the bottom of the infill wall and the first-course bricks 3 on the other side at the bottom of the infill wall, and the gap between them is the mortar joint.

[0063] Figure 7a and Figure 7b The difference lies only in the length of the aerated concrete block to suit different masonry length requirements. Of course, according to the on-site masonry situation, the other side brick 6 above the first course of the infill wall can also be directly cut to the required length on-site.

[0064] According to the above embodiments, the lengths of the two side bricks at the bottom are different, and the length of the side brick above the first course laid on the two side bricks at the bottom is different from the lengths of the two adjacent side bricks at the bottom.

[0065] The method for masonry of an infill wall using the above autoclaved aerated concrete block includes the following steps:

[0066] S120: Spread mortar on the base course of the reinforced concrete structure for leveling;

[0067] S140: Lay the side brick on one side at the bottom, the middle brick at the bottom, and the side brick on the other side at the bottom according to the preset brick laying plan; wherein, mortar is filled in the gaps between the aerated concrete blocks and the gaps between the aerated concrete blocks and the main structure to form mortar joints;

[0068] S160: Layer by layer lay the side brick above the first course and the middle brick above the first course above the first course according to the preset lapping requirements. The upper and lower layers of aerated concrete blocks are fixed by embedding the protrusions and grooves, and mortar is filled in the gaps between the aerated concrete blocks and the gaps between the aerated concrete blocks and the main structure to form mortar joints.

[0069] More specifically, in a specific embodiment of the present invention, the inclined brick at the top is masoned after the settlement of the infill wall to be masoned is stable. It should be noted that by using the present invention, the settlement time of the masoned infill wall is greatly reduced compared with the traditional masonry method and can be ignored. Generally, after the masonry of the wall is completed and the strength of the mortar laid for leveling the base course reaches the design strength, there is no settlement.

[0070] In addition, at the transfer points of the infill wall or at the cross intersections of vertical and horizontal walls where structures are arranged, for autoclaved aerated concrete blocks of upper and lower layers, it is only necessary to cut off the protrusions at the intersections of the aerated concrete blocks on-site.

[0071] For more specific implementation manners of the above-mentioned method for constructing autoclaved aerated concrete block infill walls, reference may be made to the description of the embodiments of autoclaved aerated concrete blocks mentioned above.

[0072] It can be seen from the above embodiments that for the autoclaved aerated concrete blocks and the method for constructing their infill walls provided by the present invention, the mortar joint thickness can be determined during the production of the aerated concrete blocks, and the mortar joints are fixed and unified during the masonry; the groove and protrusion plane areas of the aerated concrete blocks are 20% of the corresponding plane areas of the aerated concrete blocks, and a mortar grouting machine is used to convey mortar to fill the joints, and the mortar fullness is 80%; they are fixed by embedding the protrusions and grooves of the aerated concrete blocks, and the position dimensions of the protrusions and grooves of the aerated concrete blocks are unified, the first course of bricks of the wall is leveled and the position is accurate, the wall is vertical and the wall surface is flat; during the construction process, the amount of mortar left on the ground is greatly reduced and there is no wall surface pollution, the settlement amount of the infill wall is greatly reduced, the construction period is shortened, and the through joints of the plastering at the joint between the infill wall and the main structure in the later stage are greatly reduced. The quality of the infill wall masonry is guaranteed and conditions are created for ensuring the quality of the subsequent plastering, and the upper groove also ensures the bonding effect at the joint between the post-cast concrete ring beam, lintel and window sill coping on the upper part of the masonry and the masonry.

[0073] As described above, the autoclaved aerated concrete blocks and the method for constructing their infill walls according to the present invention are described by way of example with reference to the drawings. However, those skilled in the art should understand that various improvements can be made to the above-mentioned autoclaved aerated concrete blocks and the method for constructing their infill walls without departing from the content of the present invention. Therefore, the protection scope of the present invention should be determined by the content of the appended claims.
