Description

Technical Field

[0001] The invention relates to the technical field of building construction, and in particular to a method for reinforcing an opening of an ALC plate. Background Art

[0002] In recent years, ALC (autoclaved lightweight aerated concrete) panels have been widely used in wall construction, which is convenient and efficient to splice. During the construction of ALC panel walls, it is often necessary to reserve openings of various sizes on the ALC panel wall due to the need for mechanical and electrical pipeline layout. In order to ensure the structural strength of the ALC panel wall, the reserved openings need to be reinforced.

[0003] The traditional method of reinforcing the openings of ALC board walls is to reinforce them by setting up reinforced concrete lintels. Reinforced concrete lintels require the installation of steel bars and formwork, and then the pouring of concrete. The construction process is cumbersome, the cost is high, and the construction period is long. Moreover, when there are multiple openings in the same area at the same time, the construction of reinforced concrete lintels is more difficult. Therefore, it is necessary to provide a method for reinforcing the openings of ALC boards, which can solve the problems of cumbersome construction process, high cost, long construction period, and difficult construction of reinforced concrete lintels in the prior art. Summary of the invention

[0004] The purpose of the present invention is to provide a method for reinforcing an ALC plate opening, which can solve the problems of complicated construction procedures, high cost, long construction period and difficult construction in the prior art for reinforcing an opening of a reinforced concrete lintel.

[0005] The present invention is achieved in that:

[0006] A method for reinforcing an opening of an ALC plate comprises the following steps:

[0007] For openings with a width of less than 600 mm, no reinforcement is required;

[0008] For openings with a width of 600mm≤opening width≤1200mm, the openings shall be reinforced circumferentially along the edges of the openings;

[0009] For openings with a width greater than 1200mm, reinforcing steel is constructed inside the ALC board wall, and the reinforcing steel passes through the edge of the opening.

[0010] For openings with a width of 600mm ≤ opening ≤ 1200mm, the reinforcement construction process is as follows:

[0011] Step 1.1: Clean the base, position and lay out the guide wall, and pour the guide wall;

[0012] Step 1.2: ALC sheet layout, ALC sheet is installed vertically from one side of the guide wall to one side of the opening area;

[0013] Step 1.3: Cut and process the ALC sheet at the opening and install it, leaving the opening;

[0014] Step 1.4: Reinforce the edges of the hole;

[0015] Step 1.5: Install the ALC panels horizontally on the upper wall above the opening area;

[0016] Step 1.6: Install ALC panels vertically on the side wall from the other side of the opening area to the other side of the guide wall;

[0017] Step 1.7: Board seam processing.

[0018] The step 1.3 comprises the following sub-steps:

[0019] Step 1.3.1: In the opening area, the ALC sheet is cut according to the designed position and size of the opening to form the first ALC sheet;

[0020] Step 1.3.2: Open a hole at the intersection of the first ALC board and the opening, so that several first ALC boards are vertically installed between the top elevation of the opening and the base layer, and the opening groove is formed on the top of the several first ALC boards;

[0021] Step 1.3.3: Cutting the ALC board according to the total transverse width of the plurality of first ALC boards to form a second ALC board;

[0022] Step 1.3.4: The second ALC board is installed horizontally on top of several first ALC boards and closes the hole groove to form a hole.

[0023] In the step 1.4, the reinforcement strips are cut according to the size of the hole, and are connected and fixed to the first ALC plate and the second ALC plate around the hole; a plurality of reinforcement strips are arranged circumferentially along the inner wall of the hole, and two adjacent reinforcement strips are welded to form an integrated structure.

[0024] The cross section of the reinforcement strip is an L-shaped structure, so that the horizontal section of the reinforcement strip fits on the inner wall of the hole, and the vertical section of the reinforcement strip fits on the board surface of the ALC board.

[0025] In the step 1.5, a plurality of second ALC panels are installed horizontally from the second ALC panel located at the top of the opening to the top of the guide wall from bottom to top.

[0026] For openings with a width of more than 1200mm, the reinforcement construction process is as follows:

[0027] Step 2.1: Clean the base, position and lay out the guide wall, pour the guide wall, and enclose the base and guide wall to form the wall construction area;

[0028] Step 2.2: According to the number of openings and their designed positions and sizes, make reinforcement steel, which includes steel beams and steel columns;

[0029] Step 2.3: Install embedded plates on the base and the guide wall, so that the steel beams and steel columns are installed horizontally and vertically in the wall construction area through the embedded plates, and the wall construction area is divided into several small areas, each of which includes at least one opening and a plate installation area;

[0030] Step 2.4: Cut the ALC sheet according to the size and quantity of the sheet installation area to form a third ALC sheet, and install the third ALC sheet in the sheet installation area;

[0031] Step 2.5: Board seam processing.

[0032] The corners of the embedded plate are provided with oblong holes, and the embedded plate is adjustably mounted on the base layer and the inner wall of the guide wall through the oblong holes.

[0033] For openings with a width of less than 600mm, the specific construction process is: cleaning the base layer → positioning and laying out the guide wall → pouring the guide wall → ALC board layout → ALC board installation → board seam processing → opening positioning → wall drilling → opening grinding and repairing.

[0034] Compared with the prior art, the present invention has the following beneficial effects:

[0035] 1. The present invention uses circumferential reinforcement and steel reinforcement to reinforce reserved openings in walls of different sizes, without the need for traditional reinforced concrete lintel construction, thereby solving the problems of complicated construction procedures, high costs, long construction periods, and difficult construction for reinforced concrete lintel reinforcement openings in the prior art, effectively ensuring the construction safety of openings in the ALC board wall, while saving costs and shortening the construction period.

[0036] 2. The present invention uses flat iron, steel sections and the like to reinforce openings of different sizes. The corresponding reinforcement method and material can be flexibly selected according to the location, number and size of the openings. It is easy to obtain materials and construct, improves work efficiency, and can save construction costs as much as possible while ensuring the stability of the wall. It can be applied to the reinforcement of openings of different numbers and sizes and has a wide range of applications. BRIEF DESCRIPTION OF THE DRAWINGS

[0045] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0046] A method for reinforcing an opening of an ALC plate comprises the following steps:

[0047] Please see attached Figure 1 For opening 4 with an opening width of less than 600 mm, opening 4 is not reinforced.

[0048] For opening 4 with an opening width of less than 600mm, the ALC board wall adopts conventional technology to layout the ALC board. After the construction is completed, a hole can be directly opened at the designed position of opening 4. The specific construction process is: cleaning of base layer 1 → positioning and laying out of guide wall 2 → pouring of guide wall 2 → layout of ALC board 3 → installation of ALC board 3 → board seam processing → positioning of opening 4 → opening of wall → grinding and repair of opening 4.

[0049] Cleaning of the base layer 1, positioning and laying out of the guide wall 2, pouring of the guide wall 2, layout of the ALC board 3, installation of the ALC board 3, board seam treatment, positioning of the opening 4, wall opening, and grinding and repairing of the opening 4 are all existing construction processes and will not be repeated here.

[0050] Please see attached Figure 2 For the opening 4 with a width of 600 mm ≤ opening ≤ 1200 mm, the opening 4 is circumferentially reinforced along the edge of the opening 4 .

[0051] For opening 4 with opening width of 600mm≤opening width≤1200mm, the reinforcement construction process is as follows:

[0052] Step 1.1: Clean the base layer 1, position and lay out the guide wall 2, and pour the guide wall 2.

[0053] Cleaning the base layer 1, positioning and laying out the guide wall 2, and pouring the guide wall 2 are all existing construction processes and will not be repeated here.

[0054] Step 1.2: Arrange the ALC board 3, and install the ALC board 3 vertically from one side of the guide wall 2 to one side of the opening area.

[0055] On one side of the opening area, the layout and installation of the ALC board 3 are carried out using conventional processes, which will not be described here.

[0056] Step 1.3: Cut and process the ALC board 3 at the opening 4 and install it, leaving the opening 4.

[0057] The step 1.3 comprises the following sub-steps:

[0058] Step 1.3.1: In the hole area, the ALC board is cut according to the designed position and size of the hole 4 to form a first ALC board 5.

[0059] Step 1.3.2: Drill a hole at the intersection of the first ALC board 5 and the opening 4, so that several first ALC boards 5 are vertically installed between the top elevation of the opening 4 and the base layer 1, and a hole groove is formed on the top of the several first ALC boards 5.

[0060] Since 600 mm ≤ opening width ≤ 1200 mm, the width of the ALC board commonly used in wall construction is 600 mm, therefore, 2-3 first ALC boards 5 are usually required to be installed in the opening area.

[0061] Taking three first ALC plates 5 as an example, the upper right corner of the first first ALC plate 5 located on the left side of the opening area intersects with the opening 4, and a hole is made in the upper right corner of the first first ALC plate 5 according to the intersection position and size. Similarly, a hole is made in the upper left corner of the third first ALC plate 5 located on the right side of the opening area. The second first ALC plate 5 located in the middle of the opening area is located below the opening 4, and the top of the second first ALC plate 5 is directly cut to make the top elevation of the second first ALC plate 5 consistent with the bottom elevation of the opening 4.

[0062] Step 1.3.3: Cut the ALC board according to the total transverse width of the plurality of first ALC boards 5 to form second ALC boards 6.

[0063] Taking the assembly of three first ALC panels 5 in the opening area as an example, the length of the second ALC panel 6 is equal to the total transverse width of the three first ALC panels 5 after being assembled and installed.

[0064] Step 1.3.4: The second ALC board 6 is horizontally installed on the top of several first ALC boards 5 and closes the hole groove to form a hole 4.

[0065] The opening 4 is formed by enclosing a plurality of first ALC plates 5 installed vertically and a second ALC plate 6 installed horizontally. The total horizontal width of the plurality of first ALC plates 5 is consistent with the length of the second ALC plates 6 and is greater than the width of the opening 4, and both ends of the second ALC plates 6 extend to both sides of the opening 4 to ensure that the opening 4 is enclosed and formed.

[0066] The second ALC plate 6 installed transversely can replace the traditional reinforced concrete lintel, play the role of shaping the opening 4, protecting the opening 4 and the load, and achieve the purpose of strengthening the opening 4.

[0067] Step 1.4: Reinforce the edges of hole 4.

[0068] Specifically, the reinforcement strips 401 are cut according to the size of the opening 4, and are connected and fixed to the first ALC plate 5 and the second ALC plate 6 around the opening 4 by nails, self-tapping screws, etc.; several reinforcement strips 401 are arranged circumferentially along the inner wall of the opening 4, and two adjacent reinforcement strips 401 are welded to form an integrated structure.

[0069] The cross section of the reinforcement strip 401 is an L-shaped structure, so that the horizontal section of the reinforcement strip 401 fits on the inner wall of the hole 4, and the vertical section of the reinforcement strip 401 fits on the surface of the ALC board (the first ALC board 5 and / or the second ALC board 6).

[0070] Preferably, the reinforcement strip 401 can be made of a flat iron made of Q235B and having a size of 40×6 mm. The flat iron can be reinforced on the first ALC plate 5 and / or the second ALC plate 6 by M6 self-tapping screws, and the four reinforcement strips 401 can be connected end to end by an electric welder to form a rectangular ring structure that matches the opening 4; the opening 4 is reinforced by the rectangular ring structure.

[0071] Step 1.5: Install the ALC panels horizontally on the upper wall above the opening area.

[0072] Specifically, a plurality of second ALC panels 6 are installed horizontally from the second ALC panel 6 located at the top of the opening 4 to the top of the guide wall 2 from bottom to top.

[0073] Since the modular splicing of the second ALC plate 6 may not match the height of the upper wall, the uppermost second ALC plate 6 may need to be cut. Several transversely installed second ALC plates 6 can increase the load capacity and ensure that the opening 4 will not deform, achieving the same reinforcement effect as a traditional reinforced concrete lintel.

[0074] When the second ALC plate 6 is installed horizontally, the connection method between the second ALC plate 6 and its adjacent second ALC plate 6 and ALC plate 3 is the same as the adjacent connection method of conventional ALC plates, only the installation direction is different, which will not be repeated here.

[0075] Step 1.6: Install ALC panels vertically on the side wall from the other side of the opening area to the other side of guide wall 2.

[0076] Specifically, a plurality of ALC panels 3 are vertically installed from the other side of the opening area to the other side of the guide wall 2. The ALC panels 3 are installed using conventional construction techniques, which will not be described in detail herein.

[0077] Step 1.7: Board seam processing.

[0078] The caulking treatment of the board seams is a conventional operation for the installation and splicing of the ALC board 3 and will not be described in detail here.

[0079] Please see attached Figure 3 For openings with a width greater than 1200mm, reinforcement steel is constructed in the ALC board wall, and the reinforcement steel passes through the edge of the opening.

[0080] For opening 4 with opening width > 1200mm, the reinforcement construction process is as follows:

[0081] Step 2.1: Clean the base layer 1, position and lay out the guide wall 2, cast the guide wall 2, and enclose the base layer 1 and the guide wall 2 to form the wall construction area.

[0082] Step 2.2: According to the number of openings 4 and their designed positions and sizes, reinforcement steel is manufactured. The reinforcement steel includes steel beams 7 and steel columns 8.

[0083] Preferably, the steel beam 7 and the steel column 8 can be made of Q235B rectangular steel with a size of 100×6 mm, which has high structural strength and strong bearing capacity. The steel beam 7 and the steel column 8 can also be made of other types of steel materials according to construction requirements.

[0084] Step 2.3: Install embedded plates 9 on the base layer 1 and the guide wall 2, so that the steel beams 7 and steel columns 8 are installed horizontally and vertically in the wall construction area through the embedded plates 9, respectively, and the wall construction area is divided into several small areas, each of which includes at least one opening 4 and a plate installation area.

[0085] According to the position of the opening 4, the steel beam 7 and the steel column 8 can enclose the opening 4, the guide wall 2, the steel beam 7 and the steel column 8 can also enclose the opening 4, the base 1, the steel beam 7 and the steel column 8 can also enclose the opening 4, and the base 1, the guide wall 2, the steel beam 7 and the steel column 8 can also enclose the opening 4. The base 1, the guide wall 2, the steel beam 7 and the steel column 8 form support and reinforcement around the opening 4, without the need to construct a traditional reinforced concrete lintel, thereby ensuring the reinforcement effect of the opening 4.

[0086] Please see attached Figure 4 and attached Figure 5 Preferably, the embedded plate 9 can be made of a steel plate made of Q235B, with a size of 200×200mm and a thickness of 6mm. An oblong hole 901 of 18×30mm is provided at the four corners of the steel plate. The center of the oblong hole 901 is 50mm away from the edge of the embedded plate 9, and the center spacing of adjacent oblong holes 901 is 100mm. The embedded plate 9 can be adjustably installed on the base layer 1 and the inner wall of the guide wall 2 through four M12 expansion bolts through the oblong hole 901. The oblong hole 901 provides a certain installation adjustment range, which is convenient for compensating for the installation error and processing error of the steel beam 7 and the steel column 8, so as to ensure that the enclosure size and position of the opening 4 meet the design requirements.

[0087] The steel beam 7 and the steel column 8 can be vertically welded on the buried plate 9, with a large contact area and high connection and load reliability. The connection nodes of the steel beam 7 and the steel column 8 are fixed by welding to ensure a firm connection. The size, quantity and position of the buried plate 9, the steel beam 7 and the steel column 8 can be adaptively adjusted according to the actual construction requirements of the opening 4.

[0088] Taking a wall project as an example, a larger opening 4 is reserved in the middle of the wall, and a smaller opening 4 is reserved at the top of the wall. According to the design position and size of the two openings 4, three steel beams 7 and four steel columns 8 are cut, where:

[0089] The length of the first steel beam 7 is consistent with the width of the wall construction area, and it is installed horizontally along the bottom elevation of the smaller opening 4, and its two ends are fixed to the guide wall 2 through embedded plates 9 respectively.

[0090] The lengths of the other two steel beams 7 are consistent with the width of the larger opening 4 , and are installed transversely along the top elevation and the bottom elevation of the larger opening 4 .

[0091] The length of the two steel columns 8 is consistent with the spacing between the first steel beam 7 and the base layer 1, so that the two steel columns 8 are vertically installed along the two sides of the larger opening 4, the bottoms of the two steel columns 8 are fixed to the base layer 1 through the embedded plates 9, the tops of the two steel columns 8 are welded to the first steel beam 7, and the two ends of the other two steel beams 7 are respectively welded to the two steel columns 8. The larger opening 4 is enclosed by the two steel beams 7 and the two steel columns 8.

[0092] The length of the other two steel columns 8 is consistent with the height of the smaller opening 4, and they are vertically installed along the two sides of the smaller opening 4. The tops of the other two steel columns 8 are fixed to the guide wall 2 through the embedded plate 9, and the bottoms of the other two steel columns 8 are welded to the first steel beam 7. The smaller opening 4 is enclosed by two steel columns 8, one steel beam 7 and the guide wall 2.

[0093] The combination of the steel beams 7 and the steel columns 8 is flexible and easy to construct, and can meet the reinforcement requirements of openings 4 of different sizes, different positions, and different numbers.

[0094] For the working condition where there are multiple openings 4 on the ALC plate wall at the same time, the multiple openings 4 are reinforced by steel beams 7 and steel columns 8. Compared with the traditional reinforced concrete lintel construction method, the steel reinforcement method is more convenient, simple and efficient.

[0095] Step 2.4: Cut the ALC board according to the size and quantity of the board installation area to form a third ALC board 10, and install the third ALC board 10 in the board installation area.

[0096] The third ALC board 10 is installed in the board installation area using a conventional vertical installation method, which will not be described in detail here.

[0097] Step 2.5: Board seam processing.

[0098] The caulking of the board seams is a routine operation for the installation and splicing of ALC boards and will not be described in detail here.

[0099] When there are multiple openings 4 on the ALC sheet wall, one or more of the following construction methods can be used to reinforce the openings 4, depending on the number, size and location of the openings 4. The methods can be flexibly combined and the construction conditions are not limited. For example, if there are three openings 4 with opening widths of <600mm, 600mm < opening width <1200mm and opening width ≥1200mm on the ALC sheet wall, and the positions of the three openings 4 are relatively scattered, the three openings 4 can be constructed using the following construction methods, as shown in the attached figure. Figure 6 There are two openings 4 with a width of 600 mm or less and a width of 1200 mm or less on the ALC board wall. The two openings 4 are constructed using the circumferential reinforcement construction method. Figure 7 shown.

[0100] The above are only preferred embodiments of the present invention and are not intended to limit the scope of protection of the invention. Therefore, any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
