[0032] The following detailed description, in conjunction with the accompanying drawings, outlines some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0033] refer to Figure 1 As shown, an embodiment of this application provides a lightweight precast concrete column structure 100, which includes a plurality of columns 110 and a plurality of mounting beams 120.

[0034] Specifically, in combination Figure 1 and Figure 2 As shown, each of the columns 110 has at least two connectors 111 on its side, and the two connectors 111 are respectively located on different sides. Each mounting beam 120 has a mounting part 121 at both ends, and the two columns 110 are connected and fixed together by the mounting beams 120.

[0035] In this embodiment, the mounting portion 121 defines a mounting groove 122, and the connector 111 is snapped into the mounting groove 122. The connector 111 is detachably connected to the mounting portion 121. The mounting portion 121 forms a semi-enclosed structure. Multiple connectors 111 of the column 110 can snap into the mounting grooves 122 of multiple mounting portions 121. Each connector 111 corresponds to a mounting portion 121, and the connector 111 is detachably connected to the mounting portion 121 of the mounting beam 120. It facilitates assembly and installation, making it easy to disassemble and replace the installation beam 120. The connector 111 is inserted into the installation groove 122, and the installation part 121 forms a semi-enclosed structure to cover the connector 111. The installation part 121 covers the connector 111 and provides support and limit for the installation part 121 of the installation beam 120, so that multiple columns 110 and installation beam 120 form a relatively stable connection structure, thereby achieving the goal of balancing the construction efficiency and construction quality of the lightweight precast concrete column structure 100.

[0036] For example, the connector 111 is a connector block with a square structure so that the shape and size of the connector block match the shape and size of the mounting groove 122, ensuring the stability and directional consistency of the connector 111 during installation. The groove size of the mounting groove 122 is slightly larger than the side length of the connector block so that the connector block can slide into the mounting groove 122.

[0037] It is understood that the semi-enclosed structure formed by the mounting part 121 and the connector 111, on the one hand, allows the multiple sides of the mounting part 121 to cover the connector 111 and limit and support the connector 111, preventing the mounting beam 120 from swaying or shaking. On the other hand, it facilitates the separation of the mounting part 121 and the connector 111 through the semi-enclosed structure, making it convenient for the installation and disassembly of the mounting part 121 and the connector 111, and facilitating maintenance.

[0038] refer to Figures 1 to 3As shown, the lightweight precast concrete column structure 100 has a first direction X, a second direction Y, and a third direction Z, wherein the first direction X, the second direction Y, and the third direction Z are arranged perpendicularly to each other. For example, the first direction X is taken as the length direction of the lightweight precast concrete column structure 100, the second direction Y is taken as the width direction of the lightweight precast concrete column structure 100, and the third direction Z is taken as the height direction of the lightweight precast concrete column structure 100. For example, the mounting beams 120 are arranged along both the length and width directions of the lightweight precast concrete column structure 100. It is understood that the above definitions are only for ease of understanding the relative positional relationships of the various parts in the lightweight precast concrete column structure 100 and should not be construed as limitations on this application.

[0039] In one embodiment, alternatively, such as Figure 2 As shown, the cross-section of the mounting beam 120 is one of a square structure, a rectangular structure, or a rhombus structure. In other words, the shape of the cross-section of the mounting beam 120 will affect the assembly and connection process of the mounting part 121 and the connector 111 of the mounting beam 120. For example, if the cross-section of the mounting beam 120 is a square or rectangular structure, the square beam and the square connecting block can be aligned by the corners to enhance the anti-rotation ability. Or, if the cross-section of the mounting beam 120 is a rhombus structure, the diagonal of the rhombus structure and the moving path of the connecting block form a special guide, so that the mounting part 121 of the mounting beam 120 can be better fixed.

[0040] In one embodiment, optionally, the cross-section of the column 110 is one of a square structure, a rectangular structure, or a rhomboid structure. The two adjacent sides of the column 110 are respectively provided with the connector 111. The extension direction of the connector 111 is perpendicular to the center line direction of the column 110. Accordingly, the column 110 is a column-shaped or rod-shaped structure. The extension direction of the connector 111 is perpendicular to the center line direction of the column 110, so that the column 110 can be connected and fixed to the mounting beam 120 through the connector 111. Multiple columns 110 can be connected to each other through the mounting beam 120 to form a frame structure, ensuring the stability of the overall structure.

[0041] In summary, the two columns 110 of the lightweight precast concrete column structure 100 are connected and fixed by an installation beam 120. Multiple connectors 111 of the column 110 can be engaged with the mounting grooves 122 of multiple mounting parts 121. The connectors 111 and the mounting parts 121 correspond one-to-one. The connectors 111 are detachably connected to the mounting parts 121 of the installation beam 120, which facilitates assembly and installation, and makes it easy to disassemble and replace the installation beam 120. The connectors 111 are engaged in the mounting grooves 122, and the mounting parts 121 form a semi-enclosed structure, so that the mounting parts 121 cover the connectors 111 and provide support and limit the mounting parts 121 of the installation beam 120. This makes the multiple columns 110 and the installation beam 120 form a relatively stable connection structure, thereby achieving the goal of balancing the construction efficiency and construction quality of the lightweight precast concrete column structure 100. It can be well applied to the scenario of rapid on-site assembly construction.

[0042] refer to Figures 1 to 3 As shown, an embodiment of this application provides another lightweight precast concrete column structure 100, which includes a plurality of columns 110 and a plurality of mounting beams 120.

[0043] Specifically, in combination Figure 1 and Figure 2 As shown, each of the columns 110 has at least two connectors 111 on its side, with the two connectors 111 respectively located on different sides. Each mounting beam 120 has a mounting portion 121 at both opposite ends, the mounting portion 121 defining a mounting groove 122. The connectors 111 are engaged within the mounting groove 122, and the connectors 111 are detachably connected to the mounting portion 121. The mounting portion 121 forms a semi-enclosed structure. Two columns 110 are connected and fixed together by the mounting beams 120. Multiple connectors 111 of the column 110 can engage with the mounting grooves 122 of multiple mounting portions 121. The mounting parts 121 correspond one-to-one and are detachably connected to the mounting parts 121 of the mounting beam 120 via connectors 111, which facilitates assembly and installation, and makes it easy to disassemble and replace the mounting beam 120. The connectors 111 are inserted into the mounting grooves 122, and the mounting parts 121 form a semi-enclosed structure, so that the mounting parts 121 cover the connectors 111 and provide support and limit the mounting parts 121 of the mounting beam 120, so that multiple columns 110 and mounting beam 120 form a relatively stable connection structure, thereby achieving the goal of balancing the construction efficiency and construction quality of the lightweight precast concrete column structure 100.

[0044] In one embodiment, alternatively, referencing Figure 2 and Figure 3As shown, the mounting groove 122 is provided with a first groove 1221 and a second groove 1222. The opening direction of the first groove 1221 is perpendicular to the opening direction of the second groove 1222, so that the mounting groove 122 of the mounting part 121 can connect the connector 111 through the first groove 1221 and the second groove 1222, or move the connector 111 out of the position of the first groove 1221 or the second groove 1222, so as to adapt to a more complex spatial layout and facilitate installation and adjustment on the construction site.

[0045] Optionally, combined Figure 2 and Figure 3 As shown, the opening direction of the first slot 1221 is parallel to the center line direction of the mounting beam 120, and the opening direction of the second slot 1222 is parallel to the center line direction of the column 110. That is, the opening direction of the first slot 1221 is the same as the center line direction of the mounting beam 120, so that the connector 111 and the mounting part 121 can be moved and adjusted relative to each other through the position of the first slot 1221, and the connector 111 and the mounting part 121 can be assembled and fixed in place.

[0046] Optionally, such as Figure 3 As shown, the first slot 1221 is connected to the second slot 1222, so that the connector 111 can be moved out of the mounting part 121 from the first slot 1221 or the second slot 1222. The first slot 1221 and the second slot 1222 of the mounting part 121 are in an open state, so that the connector 111 and the mounting part 121 have a large separation space and range during the separation process. Since the slots are connected and the direction is perpendicular, the square connector can be rotated to any slot direction, realizing direction-independent installation, improving construction flexibility, and facilitating mechanical operation and construction by workers.

[0047] In one embodiment, alternatively, referencing Figure 2 and Figure 3 As shown, the mounting part 121 includes a first side plate 1211, a second side plate 1212, and a top plate 1213. The opposite ends of the top plate 1213 are respectively connected to the first side plate 1211 and the second side plate 1212. The top plate 1213, the first side plate 1211, and the second side plate 1212 together form a "U" shaped structure. Correspondingly, the connector 111 can be installed through the opening of the mounting part 121 of the "U" shaped structure. The top plate 1213, the first side plate 1211, and the second side plate 1212 can respectively abut against the connector 111, so that after the connector 111 and the mounting part 121 are assembled and positioned, the mounting beam 120 is limited and fixed, ensuring the assembly stability of the mounting beam 120.

[0048] Optionally, such as Figure 2 and Figure 3 As shown, the first side plate 1211, the second side plate 1212 and the top plate 1213 are each provided with a first mounting hole 1214, and the corresponding connector 111 is provided with a second mounting hole 1111. Each second mounting hole 1111 corresponds to one first mounting hole 1214 and is screwed together. The first mounting hole 1214 corresponds to the second mounting hole 1111, so that the first side plate 1211, the second side plate 1212 and the top plate 1213 are respectively connected and fixed to the connector 111.

[0049] In one embodiment, alternatively, such as Figure 2 As shown, the cross-section of the mounting beam 120 is one of a square, rectangular, or rhomboid structure. In other words, the shape of the cross-section of the mounting beam 120 will affect the assembly and connection process of the mounting part 121 and the connector 111. For example, if the cross-section of the mounting beam 120 is a square or rectangular structure, the square beam and the square connecting block will be aligned by the corners to enhance the anti-rotation capability. If the cross-section of the mounting beam 120 is a rhomboid structure, the diagonal of the rhomboid structure and the moving path of the connecting block will form a special guide, so that the mounting part 121 of the mounting beam 120 can be better fixed.

[0050] In one embodiment, the cross-section of the column 110 is optionally one of a square structure, a rectangular structure, or a rhomboid structure. Adjacent sides of the column 110 are respectively provided with connectors 111. The extension direction of the connectors 111 is perpendicular to the center line direction of the column 110. Accordingly, the column 110 is a columnar or rod-shaped structure. The extension direction of the connectors 111 is perpendicular to the center line direction of the column 110, so that the column 110 can be connected and fixed to the mounting beam 120 through the connectors 111. Multiple columns 110 can be connected to each other through the mounting beam 120 to form a frame structure, ensuring the stability of the overall structure.

[0051] In one embodiment, alternatively, referencing Figure 4 As shown, the column 110 includes a lightweight aggregate concrete pouring wall 112 and a hollow support member 113. The lightweight aggregate concrete pouring wall 112 covers the outer periphery of the support member 113, reducing the overall weight of the column 110. The structure is relatively lightweight, making it easy to transport and hoist. Furthermore, the lightweight aggregate concrete pouring wall 112 has fireproof and corrosion-resistant barriers, as well as fireproof, corrosion-resistant, and durable properties.

[0052] For example, according to the industry standard "Technical Specification for Lightweight Aggregate Concrete" JGJ51, the mix proportion provided by the laboratory should be converted into a construction mix proportion before construction. The quantity of lightweight aggregate to be delivered to the site should be reasonably organized according to the material usage, project volume, and construction schedule. The bulk density Q of column 110 should meet the requirement: Q≤1500kg / m3. The storage area should be isolated separately, and the storage area should be cleaned in advance to prevent the mixing of other types of aggregates or impurities. For lightweight aggregates with a water absorption rate greater than 5%, pre-wetting treatment is required. Ensure continuous and uniform spraying of the lightweight aggregate. The spraying device uses a centrifugal water pump connected to a fire hose. Spraying should be carried out according to the pre-wetting treatment time determined by the test, and the reinforcement binding should be completed.

[0053] Based on any of the above embodiments, refer to Figure 5 As shown, optionally, each column 110 includes a first column 114 and a second column 115. A connector 111 is disposed on the first column 114. The first column 114 is provided with four positioning columns and a hollow first support member 113. The four positioning columns are arranged around the first support member 113. The second column 115 is provided with multiple grouting sleeves and a hollow second support member 113. Correspondingly, there are four grouting sleeves, which are arranged around the second support member 113. The positioning columns and grouting sleeves correspond one-to-one and are grouted. The four sets of positioning columns and grouting sleeves form a circumferential constraint, ensuring the precise alignment and multi-directional rigid connection between the first column 114 and the second column 115, improving the bending moment resistance, and ensuring the overall mechanical balance. For example, the positioning columns can be steel bars, which are used to support and anchor the second column 115.

[0054] An embodiment of this utility model also provides a prefabricated building, including the lightweight precast concrete column structure 100 in the above embodiment. The prefabricated building including the lightweight precast concrete column structure 100 has all the beneficial effects of the lightweight precast concrete column structure 100, which will not be described in detail here.

[0055] In all examples shown and described herein, any specific values ​​should be interpreted as merely exemplary and not as limitations; therefore, other examples of exemplary embodiments may have different values.

[0056] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
