Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0024] The following embodiments of the present invention are described in detail with reference to the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments may be combined with each other.

[0025] refer to Figure 1 As shown, an embodiment of the present application provides a formwork structure 100 for a truss floor deck, and the formwork structure 100 for a truss floor deck includes a plate body 110, a truss assembly 120, and a positioning member 130. For example, the plate body 110 can be made of aluminum.

[0026] Specifically, combined Figure 1 and Figure 2As shown, a plurality of positioning grooves 111 and a plurality of first limiting members 112 are provided on one side of the plate body 110, and a second limiting member 121 is provided on the side of the truss assembly 120 close to the plate body 110. The second limiting member 121 is engaged with the first limiting member 112, and the cross-sectional area of ​​the truss assembly 120 gradually decreases from the plate body 110 to the truss assembly 120. The first stop 112 of the plate body 110 is engaged with the second stop 121 of the truss assembly 120, so that the plate body 110 and the truss assembly 120 can be positioned and installed, thereby achieving more accurate positioning. The cross-sectional area of ​​the truss assembly 120 gradually decreases from the positioning member 130 to the first stop block, making the structure of the truss assembly 120 lighter and reducing the overall weight. The positioning groove 111 of the plate body 110 and the positioning member 130 cooperate to be assembled and installed. The positioning member 130 is used to limit the connection of the truss assembly 120, so that the truss assembly 120 is fixedly installed on the plate body 110, reducing lateral offset or misalignment during the assembly and installation of the truss assembly 120, ensuring the connection stability of the truss assembly 120, reducing the construction difficulty, and thus improving the installation efficiency.

[0027] Exemplarily, there are multiple positioning grooves 111, multiple first limiting members 112, multiple positioning grooves 111 and multiple first limiting members 112 form an array structure arrangement, correspondingly, there are multiple second limiting members 121, each second limiting member 121 corresponds to a first limiting member 112, and there are multiple positioning members 130, each positioning member 130 corresponds to a positioning groove 111.

[0028] It is understandable that the inventors in this application found in actual work that the truss structure enhances the overall structural strength of the floor decking, and the overall structure is lightweight to facilitate high-altitude operations. However, during the actual assembly and installation process, the assembly space of the truss structure is relatively narrow. When multiple steel trusses need to be accurately installed between the corresponding two formworks, due to the limited operating space, it is difficult for construction workers to perform, resulting in an extremely cumbersome installation process. In addition, the connection process between the steel truss and the formwork is relatively complicated. Not only does it require repeated adjustment of the position and angle of the steel truss, but it is also necessary to ensure a stable connection between the components.

[0029] refer to Figure 1 and Figure 2As shown, the formwork structure 100 for the truss floor deck 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 the length direction of the formwork structure 100 for the truss floor deck, the second direction Y is the width direction of the formwork structure 100 for the truss floor deck, and the third direction Z is the height direction of the formwork structure 100 for the truss floor deck. It should be understood that the above definitions are merely for facilitating understanding of the relative positional relationships of the various components of the formwork structure 100 for the truss floor deck and should not be construed as limiting this application.

[0030] In one embodiment, optionally, reference Figure 2 and Figure 3 As shown, the first limiting member 112 includes a first limiting bar 1121 and a second limiting bar 1122, the first limiting bar 1121 and the second limiting bar 1122 are arranged opposite to each other, and the second limiting member 121 is a limiting plate, and the opposite ends of the limiting plate are respectively abutted against the first limiting bar 1121 and the second limiting bar 1122, the first limiting bar 1121 and the second limiting bar 1122 are respectively used to standardize and limit the limiting plate, to ensure stability after installation, reduce manual alignment errors, improve installation efficiency, and ensure that the limiting plate is installed along the predetermined position, the first limiting bar 1121 and the second limiting bar 1122 are respectively used to abut and limit the limiting plate, so that the truss assembly 120 is assembled and positioned on the plate body 110, thereby fixing and limiting the truss assembly 120.

[0031] In one embodiment, optionally, reference Figure 4 and Figure 5 As shown, the truss assembly 120 includes a plurality of support trusses 122 and connecting rods 123. The plurality of support trusses 122 are arranged in parallel and spaced apart along a first direction X. Any of the support trusses 122 is provided with a connecting ring 1221. The connecting rods 123 are sequentially passed through the corresponding plurality of connecting rings 1221 along the first direction X. Each support truss 122 is connected in series with the connecting rod 123 through the connecting ring 1221. The plurality of support trusses 122 are connected by the connecting rod 123 and the connecting ring 1221, which facilitates the individual replacement of damaged components or the increase or decrease of the number of supports according to span requirements, thereby maintaining the overall structural stability of the truss assembly 120.

[0032] In summary, the first limiting piece 112 of the plate body 110 of the truss floor deck is engaged with the second limiting piece 121 of the truss assembly 120, so that the plate body 110 and the truss assembly 120 can be positioned and installed, and more precise positioning is achieved. The cross-sectional area of ​​the truss assembly 120 gradually decreases from the positioning piece 130 to the first limiting block, so that the structure of the truss assembly 120 is lighter to reduce the overall weight. The positioning groove 111 of the plate body 110 and the positioning piece 130 are matched for assembly and installation. The positioning piece 130 is used to limit the connection of the truss assembly 120, so that the truss assembly 120 is fixedly installed on the plate body 110, reducing lateral offset or misalignment during the assembly and installation of the truss assembly 120, ensuring the connection stability of the truss assembly 120, reducing construction difficulty, and thereby improving installation efficiency.

[0033] refer to Figure 1 As shown, an embodiment of the present application provides another formwork structure 100 for a truss floor deck, and the formwork structure 100 for a truss floor deck includes a plate body 110 , a truss assembly 120 and a positioning member 130 .

[0034] Specifically, combined Figures 1 to 3 As shown, a plurality of positioning grooves 111 and a plurality of first limiting members 112 are provided on one side of the plate body 110, and a second limiting member 121 is provided on the side of the truss assembly 120 close to the plate body 110, and the second limiting member 121 is engaged with the first limiting member 112. The cross-sectional area of ​​the truss assembly 120 gradually decreases from the plate body 110 to the truss assembly 120, and the cross-sectional area of ​​the truss assembly 120 gradually decreases from the positioning member 130 to the first limiting block, so that the structure of the truss assembly 120 is relatively light to reduce the overall weight.

[0035] In this embodiment, one side of the positioning member 130 is engaged with the positioning groove 111, and the side of the positioning member 130 facing away from the plate body 110 is detachably connected to the truss assembly 120, and the first limiting member 112 of the plate body 110 is engaged with the second limiting member 121 of the truss assembly 120, so that the plate body 110 and the truss assembly 120 are positioned and installed, and more precise positioning is achieved. The positioning groove 111 of the plate body 110 and the positioning member 130 cooperate for assembly and installation. The positioning member 130 is used to limit the connection of the truss assembly 120, so that the truss assembly 120 is fixedly installed on the plate body 110, reducing lateral offset or misalignment during the assembly and installation of the truss assembly 120, ensuring the connection stability of the truss assembly 120, reducing construction difficulty, and thereby improving installation efficiency.

[0036] In one embodiment, optionally, the first limiting member 112 includes a first limiting bar 1121 and a second limiting bar 1122, the first limiting bar 1121 and the second limiting bar 1122 are arranged opposite to each other, the second limiting member 121 is a limiting plate, and the opposite ends of the limiting plate are respectively abutted against the first limiting bar 1121 and the second limiting bar 1122, the first limiting bar 1121 and the second limiting bar 1122 are respectively used to standardize and limit the limiting plate, to ensure stability after installation, reduce manual alignment errors, improve installation efficiency, and ensure that the limiting plate is installed along a predetermined position, the first limiting bar 1121 and the second limiting bar 1122 are respectively used to abut and limit the limiting plate, so that the truss assembly 120 is assembled and positioned on the plate body 110, thereby fixing and limiting the truss assembly 120.

[0037] like Figure 3 As shown, further, the first limiting bar 1121 and the second limiting bar 1122 are both semi-enclosed frame bar structures, and the opening of the first limiting bar 1121 and the opening of the second limiting bar 1122 are arranged relative to each other, so that the first limiting bar 1121 and the second limiting bar 1122 jointly surround the edge part of the limiting plate, which is suitable for scenarios of rapid positioning and standardized installation.

[0038] Optionally, refer to Figure 3 As shown, the first limiting member 112 also includes a third limiting strip 1123, and the third limiting strip 1123 is arranged between the first limiting strip 1121 and the second limiting strip 1122. The limiting plate is provided with a first positioning hole 1211. When the limiting plate is engaged with the first limiting member 112, the third limiting strip 1123 is engaged with the first positioning hole 1211. The third limiting strip 1123 is used to constrain the displacement of the limiting plate in the XY direction, reducing the misalignment or offset of the limiting plate. The third limiting strip 1123 is aligned with the first positioning hole 1211 to improve the fixing reliability of the limiting plate and form multi-dimensional precise positioning. For example, when the formwork structure is subjected to the gravity or vibration of concrete pouring, the third limit bar 1123 can significantly improve the shear resistance of the limit plate, avoid dislocation or offset of the truss assembly 120 due to displacement, enhance the anti-offset and anti-vibration performance of the truss assembly 120, and ensure the stability of the connection between the plate body 110 and the truss assembly 120.

[0039] Alternatively, as Figure 2As shown, there are multiple first limit members 112, and the multiple first limit members 112 are arranged in an array structure, and each first limit member 112 corresponds to a limit plate, which can evenly distribute the load of the truss assembly 120, avoid structural failure (such as deformation or cracking) due to local stress concentration, and improve the overall stability under the dynamic load of concrete pouring. Each limit plate is independently positioned by the corresponding first limit member 112 to form a "multi-point support" structure, which effectively suppresses the planar displacement of the truss assembly 120 along the XY direction.

[0040] Optionally, each of the first positioning holes 1211 corresponds to one of the third limit bars 1123. When individual third limit bars 1123 are damaged, the positioning function of the overall structure can still be maintained, thereby reducing systemic risks. The multiple third limit bars 1123 of the plate body 110 cooperate with the first positioning holes 1211 of the corresponding limit plates to limit the planar displacement of the truss assembly 120 along the XY direction. The arrayed design of the third limit bars 1123 can match the non-uniform loads of the truss assembly 120 at different positions, thereby ensuring the stability of the connection between the plate body 110 and the truss assembly 120.

[0041] In one embodiment, optionally, reference Figure 3 and Figure 4 As shown, the truss assembly 120 includes a plurality of support trusses 122 and connecting rods 123. The plurality of support trusses 122 are arranged in parallel and spaced apart along a first direction X. Each support truss 122 is provided with a connecting ring 1221. The connecting rods 123 are sequentially passed through the corresponding plurality of connecting rings 1221 along the first direction X. Each support truss 122 is connected in series with the connecting rod 123 through the connecting ring 1221. The plurality of support trusses 122 are connected by the connecting rod 123 and the connecting ring 1221, which facilitates the individual replacement of damaged components or the increase or decrease of the number of supports according to span requirements, thereby maintaining the overall structural stability of the truss assembly 120.

[0042] Optionally, refer to Figure 1 and Figure 3As shown, there are multiple connecting rods 123. Each supporting truss 122 is provided with multiple connecting rings 1221 along the second direction Y. Each connecting rod 123 corresponds to a connecting ring 1221 of a supporting truss 122, so that the truss assembly 120 forms a frame structure. The second direction Y is arranged at an angle to the first direction X. That is, each supporting truss 122 is provided with multiple connecting rings 1221 along the width direction of the formwork structure 100 of the truss floor deck. The multiple connecting rings 1221 are arranged at intervals to facilitate the corresponding insertion of the connecting rods 123, ensuring load distribution at the connection locations. The multiple supporting trusses 122 and the multiple connecting rods 123 together form a frame structure to improve the overall stiffness of the truss assembly 120, thereby improving the stability of the overall structure. Exemplarily, the multiple supporting trusses 122 are arranged along the first direction X, and the multiple connecting rods 123 are arranged along the second direction Y.

[0043] Alternatively, as Figure 3 and Figure 4 As shown, the supporting truss 122 includes a plurality of triangular brackets 1222, a first mounting rod 1223 and two second mounting rods 1224. The plurality of triangular brackets 1222 are arranged in parallel and spaced apart along the second direction Y. The top angles of the plurality of triangular brackets 1222 are connected to the first mounting rod 1223, and the bottom angles of the plurality of triangular brackets 1222 are connected to the second mounting rod 1224. The rigid structure of the triangular bracket 1222 can effectively share the load and avoid deformation of the frame structure. The top angle of the triangular bracket 1222 is connected to the first mounting rod 1223 to bear the top load, and the bottom angle of the triangular bracket 1222 is connected to the second mounting rod 1224 to form a bottom support frame, thereby enhancing the structural symmetry and stability. The plurality of triangular brackets 1222 can form a three-dimensional grid structure.

[0044] Exemplarily, the triangular bracket 1222 is fixedly connected to the second limiting member 121 through the second mounting rod 1224 , so that the triangular bracket 1222 is assembled and positioned with the plate body 110 through the second limiting member 121 . The triangular bracket 1222 is used to provide structural support and is assembled on the plate body 110 .

[0045] In one embodiment, optionally, reference Figure 5 and Figure 6As shown, the positioning member 130 includes a first positioning plate 131 and a second positioning plate 132, the first positioning plate 131 is connected to the second positioning plate 132 and defines a second positioning hole 133, the second mounting rod 1224 is passed through the second positioning hole 133 to limit the second mounting rod 1224, the shape and size of the second positioning hole 133 match the diameter of the second mounting rod 1224, the second mounting rod 1224 is standardized and limited by the hole wall of the second positioning hole 133, and the second mounting rod 1224 is jointly covered by the first positioning plate 131 and the second positioning plate 132 to avoid local stress concentration and limit the relative displacement of the second mounting rod 1224 along the first direction X.

[0046] Further, refer to Figure 6 As shown, the first positioning plate 131 and the second positioning plate 132 are respectively provided with an arcuate groove. The arcuate groove of the first positioning plate 131 corresponds to the arcuate groove of the second positioning plate 132. When the first positioning plate 131 and the second positioning plate 132 are assembled and connected, the arcuate groove of the first positioning plate 131 and the arcuate groove of the second positioning plate 132 define a second positioning hole 133. The second positioning hole 133 is used to pass the second mounting rod 1224. When the formwork structure 100 of the truss floor deck is poured with concrete, it is prevented from vibrating and causing the truss assembly 120 to shake or float. Exemplarily, the second positioning hole 133 is fixedly installed on the plate body 110. The second positioning hole 133 is provided with two limiting grooves. The two second mounting rods 1224 are both passed through the same second positioning hole 133, and one second mounting rod 1224 corresponds to one limiting groove of the second positioning hole 133, thereby improving the positioning and fixing effect of the positioning member 130, reducing the assembly and installation process, and thus improving the installation efficiency.

[0047] Alternatively, as Figure 6 As shown, the first positioning plate 131 is provided with a locking member 1311 and a guide column 1312, and the second positioning plate 132 is provided with a mounting hole 1321 and a guide hole 1322. The locking member 1311 is passed through the mounting hole 1321 and is threadedly connected to the hole wall of the mounting hole 1321. The guide column 1312 is passed through the guide hole 1322 so that the first positioning plate 131 and the second positioning plate 132 are detachably connected. The guide column 1312 corresponds to the guide hole 1322 one by one. The guide column 1312 is used to achieve preliminary positioning of the assembly connection of the first positioning plate 131 to ensure the positioning stability of the second positioning plate 132 and the first positioning plate 131. The locking member 1311 is used to fix the first positioning plate 131 and the second positioning plate 132. After rotating the locking member 1311, the first positioning plate 131 and the second positioning plate 132 can be separated, and the tightness between the first positioning plate 131 and the second positioning plate 132 can be adjusted to facilitate adjustment and replacement of the positioning member 130.

[0048] Furthermore, if Figure 6 As shown, the second positioning plate 132 is provided with a boss 1323, and the guide hole 1322 is provided on the boss 1323. The boss 1323 is connected to the first positioning plate 131 and defines the second positioning hole 133. Exemplarily, the number of guide posts 1312 is four, and the number of corresponding guide holes 1322 is four.

[0050] In all examples shown and described herein, any specific values ​​should be interpreted as merely exemplary and not limiting, and thus other examples of the exemplary embodiments may have different values.

[0051] The above-described embodiments merely illustrate several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that variations and modifications are possible without departing from the scope of the present invention, and such variations and modifications are fully within the scope of protection of the present invention.
