Description

Technical Field

[0001] This invention relates to the technical field of building construction, and in particular to a CT high-precision hollow block and its construction method. Background Technology

[0002] With the continuous advancement and development of modern industrial technology, house construction can now be achieved through mass production, i.e., prefabricated buildings. Prefabricated buildings are constructed by transporting prefabricated components produced in a factory to an assembly site for assembly. Prefabricated concrete structures, steel structures, and wood structures can all be called prefabricated buildings. Among these, the most commonly used prefabricated component is concrete blocks. Concrete blocks are characterized by high strength, high density, and durability, resulting in high structural stability and good compressive strength. However, due to the inherent characteristics of concrete, it is difficult to achieve a smooth and flat surface on concrete blocks. Therefore, after the masonry is completed, the wall needs to be plastered or painted to make the surface smooth and flat. In addition, the processing precision of concrete blocks is limited, and the blocks are connected by applying mortar, making construction quite difficult. Summary of the Invention

[0003] To overcome the above-mentioned technical problems, the present invention provides a CT high-precision hollow block and a construction method thereof.

[0004] The present invention provides a CT high-precision hollow block and its construction method, which adopts the following technical solution: A high-precision CT hollow block includes a block body. A tenon is provided at the top of the block body. Four holes are formed on the upper surface of the tenon, arranged sequentially from left to right, and vertically penetrating the block body. Tie bar grooves are formed on the front and rear shoulders of the tenon, with two sets of tie bar grooves symmetrically arranged. Tie bar grooves are formed on the upper surface of the tenon, extending through the front and rear sides of the holes, and perpendicular to the tie bar grooves. The configuration includes a tie groove that is connected to two sets of tie bar grooves, a tenon groove at the bottom of the block body that is adapted to a tongue and groove tenon, a horizontal pipeline groove on the concave surface of the tenon groove that runs through the block body from left to right, a dovetail tenon groove on the left side of the block body, a dovetail tenon on the right side of the block body that is adapted to the dovetail tenon groove, and vertical reinforcing ribs at the four corners of each hole.

[0005] By adopting the above technical solution, and by setting matching dovetail grooves and dovetail tenons on the left and right sides of the block body, the stability and safety of the block can be greatly improved. During assembly, the dovetail tenon of one block is inserted into the dovetail groove of another block from top to bottom through hoisting, and the left and right blocks are directly connected by mortise and tenon interlocking. The connection of the left and right sides eliminates the process of applying mortar, which not only reduces construction time, saves materials, and improves efficiency, but also improves assembly accuracy through the dovetail tenon and tenon interlocking, ensuring the integrity, stability and reliability of the wall.

[0006] A CT-based high-precision hollow block construction method includes the following steps: S1: Pre-construction preparation: Draw the elevation block layout of CT high-precision hollow blocks according to the construction drawings; S2: Clean the base layer of the interior partition wall, and measure and lay out the lines according to the construction drawings and set up the bricklaying rod; S3: Determine the location of the core column and tie bar according to the facade block layout. The core column is evenly set along the length of the wall. The core column is equipped with embedded steel bars. The embedded steel bars pass through the holes of the block. The bottom of the embedded steel bars is connected to the pre-embedded steel bars in the foundation or foundation beam. The embedded steel bars are tied in sections as the wall is built. The concrete in the core column is also poured in sections. The grouting position of the core column at the top of the wall is pre-drilled on the block. After the top of the embedded steel bars is welded to the pre-embedded steel plate of the top plate, the last section of concrete core column is poured from the grouting hole. S4: Begin constructing the interior partition wall, adjusting the flatness and verticality of the wall as needed during the block assembly process; S5: Connection treatment between block wall and beam bottom or top slab.

[0007] By adopting the above technical solution, the bottom of the internal reinforcing steel bar of the core column is connected to the pre-embedded reinforcing steel bar in the foundation or foundation beam, and the top is welded to the pre-embedded steel plate, which ensures the integrity and stability of the masonry wall. The internal reinforcing steel bar is tied in sections as the wall is built, and the verticality of the internal reinforcing steel bar of the core column can be adjusted according to the construction situation to ensure that the internal reinforcing steel bar is tightly connected with the upper and lower pre-embedded parts, thereby improving the stability and reliability of the wall. The core column concrete is poured in sections to ensure that the core column concrete is poured densely.

[0008] Preferably, the tie bars are evenly distributed along the height of the wall, with two tie bars in each group. A second steel plate is pre-embedded at the corresponding position of the tie bar on the main body. One end of the tie bar is welded to the second pre-embedded steel plate, and the other end is bent at 90°. The tie bars are arranged to run through the length of the wall and are placed in the tie bar groove of the block.

[0009] By adopting the above technical solution, tie bars are evenly set along the height of the wall. One end of the tie bar is welded to the main embedded steel plate, which can tightly connect the masonry wall with the main structure to form a stable overall structure, thereby improving the stability of the wall.

[0010] Preferably, the elevation block layout of the CT high-precision hollow block adopts BIM technology. When arranging the blocks, staggered joints are made according to the specifications of the CT high-precision hollow block, the thickness of the mortar joints, the size of the door and window openings, the height of the lintels, the height of the horizontal tie beams, the position of the core column, the size of the reserved openings, and the laying positions of pipelines, switches, and sockets. At the same time, standard CT high-precision hollow blocks, cut blocks, and other supporting blocks are pre-processed in the factory according to the BIM elevation block layout.

[0011] By adopting the above technical solution, a BIM elevation block layout drawing of CT high-precision hollow blocks is drawn in advance according to the construction drawings before construction. Based on the BIM elevation block layout drawing, standard CT high-precision hollow blocks, cutting blocks and other blocks are prepared. On the one hand, the materials for masonry walls can be prepared in advance, and the assembly efficiency can be improved. On the other hand, the elevation block layout drawing can help to rehearse the block layout, avoid some problems that may be encountered during construction, and solve the problems in advance.

[0012] Preferably, the first layer of bricks used in the construction of the inner partition wall is made of moisture-proof blocks, and the structure of the moisture-proof blocks is the same as that of CT high-precision hollow blocks.

[0013] By adopting the above technical solution, the first layer of bricks in the wall is built with moisture-proof blocks, which can prevent underground moisture from seeping upwards along the wall and gradually making the wall damp, thereby affecting the hygiene of the living environment and the load-bearing capacity of the wall structure.

[0014] Preferably, the CT high-precision hollow block is a building block made of desulfurized gypsum.

[0015] By adopting the above technical solutions, CT high-precision hollow blocks are made of desulfurized gypsum, which has advantages such as energy saving, sound insulation, heat insulation, and fire resistance. Moreover, CT high-precision desulfurized gypsum blocks have a smooth surface and high manufacturing precision, which not only enables the wall to be plaster-free, thus saving a lot of material consumption, but also enables the wall to be assembled with high precision, reducing assembly difficulty and improving assembly efficiency.

[0016] Preferably, when constructing the interior partition wall, the upper and lower blocks are connected by adhesive mortar. The adhesive mortar is laid and assembled at the same time, and the length of each mortar layer does not exceed the length of one block. The thickness of the horizontal mortar joints of the blocks is controlled within the range of 1-3mm. The left and right blocks are directly connected by dovetail tenons and dovetail grooves.

[0017] Preferably, the embedded steel bars include a number of longitudinal steel bars and a number of horizontal stirrups. The stirrups are welded to the longitudinal steel bars, and the tie bars are connected to the embedded steel bars by tie bars. The tie bars and tie bars are completely wrapped in the adhesive mortar and CT high-precision hollow block.

[0018] Preferably, vertical water and electricity pipelines are pre-laid before the interior partition wall is constructed, and the vertical water and electricity pipelines are installed through the holes in the masonry blocks; the horizontal water and electricity pipelines are installed in conjunction with the wall construction, and the horizontal water and electricity pipelines are installed in the horizontal pipeline grooves of the masonry blocks.

[0019] Preferably, during the masonry process, electrical distribution boxes and door and window openings are reserved according to the construction drawings. The walls around the door and window openings are made of solid blocks, the top of the door and window openings are constructed with opening lintel blocks and then poured with concrete, and a window sill beam is set at the bottom of the window opening.

[0020] By adopting the above technical solutions, vertical water and electricity pipelines are pre-laid and run through the holes in the masonry blocks, which can hide the pipelines and make the wall surface more beautiful. The distribution box and door and window openings are also reserved during the construction of the wall, avoiding the quality hazards of wall cracking caused by cutting grooves and openings in the wall. The tie bars and the embedded steel bars are connected by tie bars, so that the core column and tie bars can cooperate with each other to form a stable whole structure of the masonry wall, thereby improving the stability of the wall.

[0021] In summary, the present invention has the following beneficial effects: 1. The present invention relates to a CT high-precision hollow block and its construction method. By setting matching dovetail grooves and dovetail tenons on the left and right sides of the block body, the stability and safety of the block can be greatly improved. During assembly, the dovetail tenon of one block is inserted into the dovetail groove of another block from top to bottom by hoisting. The left and right blocks are directly connected by mortise and tenon interlocking, eliminating the need for mortar application. This not only reduces construction time, saves materials, and improves efficiency, but also improves assembly accuracy through the dovetail tenon interlocking, ensuring the integrity, stability, and reliability of the wall.

[0022] 2. This invention relates to a CT high-precision hollow block and its construction method. The bottom of the internal reinforcing steel bar in the core column is connected to the pre-embedded reinforcing steel bar in the foundation or foundation beam, and the top is welded to a pre-embedded steel plate, ensuring the integrity and stability of the masonry wall. The internal reinforcing steel bar is tied in sections during the wall construction, allowing adjustment of the verticality of the internal reinforcing steel bar according to the construction situation, ensuring a tight connection between the internal reinforcing steel bar and the upper and lower pre-embedded parts, thereby improving the stability and reliability of the wall. The core column concrete is poured in sections to ensure dense pouring. Tie bars are evenly arranged along the wall height, with one end of the tie bar welded to the main pre-embedded steel plate, tightly connecting the masonry wall to the main structure. The tie bars and internal reinforcing steel bar are connected by tie bars, allowing the core column and tie bars to cooperate with each other, forming a stable overall structure for the masonry wall, thereby improving the stability of the wall.

[0023] 3. The present invention provides a CT high-precision hollow block and its construction method. Before construction, a BIM elevation block layout diagram of the CT high-precision hollow block is drawn according to the construction drawings. Based on the BIM elevation block layout diagram, standard CT high-precision hollow blocks, cutting blocks, and other supporting blocks are prepared. On the one hand, this can ensure the material preparation for the masonry wall and improve the assembly efficiency; on the other hand, the elevation block layout diagram can help to rehearse the block layout and avoid some problems that may be encountered during construction, thus solving the problems in advance.

[0028] The following is in conjunction with the appendix Figure 1-5 The present invention will be described in further detail below.

[0029] Example 1 This embodiment discloses a high-precision hollow block for CT scans. (Refer to...) Figures 1-5 The block body 1 includes a tenon 2 at the top, four holes 3 on the upper surface of the tenon 2, arranged from left to right, vertically penetrating the block body 1. Tie bar grooves 4 are provided on the front and rear shoulders of the tenon 2, symmetrically arranged in two sets. Tie bar grooves 5 are provided on the upper surface of the tenon 2, extending through the front and rear sides of the holes 3, perpendicular to the tie bar grooves 4, and connected to the two sets of tie bar grooves 4. A mortise 6 is provided at the bottom of the block body 1, fitting the tenon 2. A horizontal pipe groove 7 is provided on the concave surface of the mortise 6, penetrating the block body 1 laterally. A dovetail tenon 8 is provided on the left side of the block body 1, and a dovetail tenon 8 is machined on the right side of the block body 1. The dovetail tenon 9 and dovetail groove 8 are adapted to each other. The inner edge of each hole 3 is provided with four vertical reinforcing ribs 10 at the four corners of the cavity. The block body 1 is made of desulfurized gypsum, which has the advantages of energy saving, sound insulation, heat insulation and fire resistance. Moreover, the CT high-precision desulfurized gypsum block has a smooth surface and high manufacturing precision. It can not only realize the wall without plastering and save material consumption, but also realize the high-precision assembly of the wall. During assembly, the dovetail tenon 9 of one block is inserted into the dovetail groove 8 of another block from top to bottom by hoisting. The left and right blocks are connected directly by tenon and mortise. The connection of the block surface eliminates the process of applying mortar. It can not only reduce construction time, save materials and improve efficiency, but also improve the assembly precision of the dovetail tenon and mortise, ensuring the integrity, stability and reliability of the wall.

[0030] Example 2 The difference between this embodiment and Embodiment 1 is that this embodiment provides a CT high-precision hollow block and a construction method, including the following steps: S1: Before construction, technical preparations, material and equipment preparation, and training and briefing for wall assembly personnel are conducted to ensure that the equipment is in good working order and that the assembly personnel are familiar with the design drawings and related technical documents. Before construction, a BIM elevation block layout drawing of CT high-precision hollow blocks is prepared according to the construction drawings. The blocks are arranged in a staggered manner according to the specifications of the CT high-precision hollow blocks, the thickness of the mortar joints, the size of door and window openings, the height of lintels, the height of horizontal tie beams, the position of the core column, the size of reserved openings, and the location of pipelines, switches, and sockets. Simultaneously, standard CT high-precision hollow blocks, cut blocks, and other auxiliary blocks are pre-fabricated in the factory according to the BIM elevation block layout drawing. The minimum size of the cut auxiliary blocks must not be less than one-quarter of the standard CT high-precision hollow block. The elevation block layout is drawn using BIM technology. Figure 1 On the one hand, it can prepare materials for masonry walls and improve assembly efficiency; on the other hand, BIM elevation block layout can help to rehearse the block layout, avoid some problems that may be encountered during construction, and solve problems in advance.

[0031] S2: Clean the base layer of the interior partition wall at the bottom, top, and junction with other walls, removing debris and dust to ensure the flatness and verticality of the construction. Level the bottom base layer using concrete wall pad 17. Construction can only begin after the compressive strength of the concrete wall pad 17 reaches 1.2MPa. According to the design of the wall position in the construction drawings, mark the wall edge lines and door and window opening edge lines or control lines at the junction of the base layers on both sides of the partition wall. Set up gauge rods at the inside and outside corners of the partition wall, and the spacing between gauge rods should not exceed 15m.

[0032] S3: Determine the locations of core columns 11 and tie bars 12 based on the BIM elevation block layout. Core columns 11 are evenly distributed along the length of the wall. Embedded steel bars 13 are installed at the locations of core columns 11, with several embedded steel bars 13 penetrating through the holes 3 in the masonry blocks. The bottom of the embedded steel bars 13 is connected to the pre-embedded steel bars in the foundation or foundation beam, and the top is welded to the top pre-embedded steel plate to ensure the integrity and stability of the masonry wall. The embedded steel bars 13 are tied in sections as the wall is constructed, allowing for adjustment of the verticality of the embedded steel bars 13 in the core columns 11 according to the construction situation, ensuring a tight connection between the embedded steel bars 13 and the upper and lower pre-embedded parts, thereby improving the stability and reliability of the wall. The concrete inside the core columns 11 is also poured in sections. Grouting holes are pre-drilled on the masonry blocks at the grouting locations of the core columns 11 at the top of the wall, and the last section of concrete for the core column 11 is poured through these holes to ensure the core column 11 is densely packed. Tie bars 12 are installed along the height of the wall. The tie bars 12 are evenly distributed, with two tie bars in each group. A steel plate 2 is embedded at the corresponding position of the tie bar 12 on the main body. One end of the tie bar 12 is welded to the embedded steel plate 2, and the other end has a 90° hook. The tie bar 12 is continuously installed in the tie bar groove 4 of the block along the length of the wall. The tie bar 12 can tightly connect the masonry wall with the main structure, forming a stable overall structure. The internally embedded steel bars 13 include several longitudinal steel bars and several horizontal stirrups 15. The stirrups 15 are welded to the longitudinal steel bars. The stirrups 15 are evenly distributed along the height of the wall. The tie bars 12 and the internally embedded steel bars 13 are tightened together by tie bars 16. The tie bars 16 are placed in the tie bar groove 5. The tie bars 12 and 16 are completely encased in the upper and lower masonry blocks and the adhesive mortar 14, so that the core column 11 and the tie bars 12 can cooperate with each other, making the masonry wall form a stable overall structure, thereby improving the stability of the wall.

[0033] S4: Begin constructing the interior partition wall. Connect the upper and lower blocks with adhesive mortar 14. Lay and assemble the adhesive mortar 14 as you go, ensuring that the length of each mortar application does not exceed the length of one block. Control the thickness of the horizontal mortar joints between the blocks within the range of 1-3mm. Assemble and connect the left and right blocks directly through the interlocking of dovetail grooves 8 and dovetail tenons 9. Select blocks with flat bottoms without any grooves at the bottom of the wall, and select blocks with flat tops at the top. Select blocks with flat surfaces at the width of the wall. Adjust the flatness and verticality of the wall as needed during the block assembly process.

[0034] S5: Flexible connection is adopted at the connection between the block wall and the bottom or top of the beam. A gap of not less than 20mm is left at the joint. The gap is filled with 18 granulated polystyrene mortar. After the filling material is stable, the joint is treated with 14 adhesive mortar and fiberglass mesh for crack resistance.

[0035] Among them, such as Figures 1-5As shown, the first layer of bricks in the partition wall is made of moisture-proof blocks to prevent underground moisture from seeping upwards along the foundation and gradually making the wall damp, thereby affecting the hygiene of the living environment and the load-bearing capacity of the wall structure. The moisture-proof block structure is the same as that of CT high-precision hollow blocks.

[0036] Among them, such as Figures 1-5 As shown, vertical water and electricity pipelines are pre-laid before the interior partition wall is built. The vertical water and electricity pipelines are installed through the holes 3 in the masonry blocks. The horizontal water and electricity pipelines are installed in conjunction with the wall construction. The horizontal water and electricity pipelines are installed in the horizontal pipeline grooves 7 in the masonry blocks to hide the pipelines and make the wall surface more aesthetically pleasing. During the masonry process, the distribution box and door and window openings are reserved according to the construction drawings. The walls around the door and window openings are made of solid blocks. The top of the door and window openings is built with opening lintel blocks and then poured with concrete. Window sill beams are set at the bottom of the window openings to avoid the quality hazard of wall cracking caused by slotting and opening in the wall.

[0037] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments that can be applied to other fields.
