Description

Technical Field

[0001] This invention relates to the field of underground waterproofing technology, and in particular to a steel truss, steel skeleton, underground wall, and underground wall construction process. Background Technology

[0002] As the outer enclosure wall of a basement structure that directly contacts the outdoor environment, the basement exterior wall primarily serves to retain soil and water, and bear horizontal loads and some vertical loads. Its design must comprehensively consider wall thickness, reinforcement methods, waterproofing construction, and relevant regulatory requirements to ensure the safety and long-term durability of the basement structure.

[0003] In existing construction techniques, water-stop tie rods are the mainstream solution for waterproofing basement exterior walls. This method achieves waterproofing by inserting the water-stop tie rod through the reinforcing mesh and concrete, using water-stop plates on the tie rod to extend the water penetration path. However, this technique has significant drawbacks: firstly, the exposed ends of the water-stop tie rods need to be waterproofed separately during the concrete formwork removal stage, significantly reducing overall construction efficiency; secondly, the water-stop plates are usually placed along the central axis of the reinforcing mesh, making it easy for groundwater to seep into the basement along the tie rods, severely weakening the waterproofing effect of the basement exterior walls and easily causing steel corrosion, thus posing a potential threat to structural safety.

[0004] Therefore, there is an urgent need for a steel truss, steel skeleton, underground wall and underground wall construction technology to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide a steel truss, steel skeleton, underground wall, and underground wall construction process that blocks the seepage path of groundwater at the underground wall, thereby improving the waterproofing effect and the construction efficiency of the underground wall.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] In a first aspect, a steel truss is provided, including two longitudinal steel bars arranged at intervals along the wall thickness direction, the two longitudinal steel bars being connected by multiple connecting steel bars, the multiple connecting steel bars being arranged at intervals along the vertical direction, and each longitudinal steel bar being provided with multiple connectors arranged at intervals along the vertical direction, the connectors being arranged off-axis from the connecting steel bars along the wall thickness direction, and the connectors being able to be connected to the formwork.

[0008] Optionally, one end of the connector is connected to the longitudinal reinforcing bar, and the other end of the connector is provided with a hook that can be engaged with the formwork.

[0009] Optionally, multiple connectors on one of the two longitudinal reinforcing bars correspond one-to-one with multiple connectors on the other of the two longitudinal reinforcing bars, and the height of the connector is the same as the height of the corresponding connector.

[0010] Optionally, the connecting bars are perpendicular to the longitudinal bars.

[0011] Secondly, a steel reinforcement cage is provided, including horizontal steel bars and multiple steel trusses as described in the first aspect, wherein the multiple steel trusses are arranged at intervals along the length of the wall, and the horizontal steel bars are connected to the longitudinal steel bars of the multiple steel trusses.

[0012] Optionally, multiple horizontal reinforcing bars are provided, the number of horizontal reinforcing bars is no greater than the number of connectors on a longitudinal reinforcing bar, and the horizontal reinforcing bars can be connected to the upper surface of any connector.

[0013] Thirdly, a basement wall is provided, comprising a concrete layer and a steel reinforcement cage as described in the second aspect, the steel reinforcement cage being located within the concrete layer.

[0014] Fourthly, a construction process for underground walls is provided, applicable to the underground walls described in the third aspect, including the following steps:

[0015] S1. Use steel bar processing equipment to connect multiple connecting steel bars to two longitudinal steel bars; then, use steel bar processing equipment to process multiple connectors on the longitudinal steel bars to form a steel truss.

[0016] S2. Use a processing mold table to connect the longitudinal and horizontal steel bars of multiple steel trusses to form a steel skeleton;

[0017] S3. Install formwork on both the inner and outer sides of the underground wall, and connect the formwork to multiple connectors on the corresponding sides;

[0018] S4. Pour concrete.

[0019] Optionally, step S1 specifically includes the following steps:

[0020] S11. Determine the first preset spacing between the two longitudinal steel bars according to the thickness of the underground wall, and send the two longitudinal steel bars into the steel bar processing equipment. The steel bar processing equipment adjusts the distance between the two longitudinal steel bars according to the first preset spacing.

[0021] S12. Multiple connecting steel bars are sequentially fed into the steel bar processing equipment at the second preset spacing, and the steel bar processing equipment connects the fed connecting steel bars with two longitudinal steel bars.

[0022] S13. Using steel bar processing equipment, multiple connectors are processed on the longitudinal steel bars to form a steel truss.

[0023] Optionally, step S2 specifically includes the following steps:

[0024] S21. Determine the number of steel trusses and the spacing between two adjacent steel trusses according to the design requirements of the underground wall.

[0025] S22. Install multiple steel trusses at intervals onto the processing mold table;

[0026] S23. Use a processing mold to enclose the horizontal steel bars to the outside of multiple steel trusses, and fix the horizontal steel bars to the longitudinal steel bars of the multiple steel trusses.

[0027] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0028] This invention provides a steel truss, a steel skeleton, an underground wall, and a construction process for the underground wall. Connecting steel bars link two longitudinal steel bars into a single unit, improving the overall integrity of the steel truss, enhancing the overall strength of the steel skeleton, and ensuring the structural reliability of the underground wall. During the underground wall's service life, groundwater will seep into the inner side of the underground wall along the connectors located on the outer side. The staggered arrangement of the connectors and connecting steel bars blocks the seepage path of groundwater within the steel truss, preventing further infiltration. This not only helps reduce groundwater erosion of the steel truss but also improves the waterproofing effect of the underground wall. During the underground wall construction phase, the formwork can be directly connected to the connectors, and there is no need to dismantle the formwork after concrete pouring. This is not only convenient and quick but also eliminates the need for separate waterproofing treatment after formwork removal, significantly improving the construction efficiency of the underground wall. The formwork is connected to the steel truss through multiple connectors, which helps improve the stability of the formwork installation on one side of the steel truss, ensuring the reliability of concrete pouring during underground wall construction. Furthermore, once the specifications of the underground wall are determined, the steel truss becomes a standardized component, which helps to accelerate the production rate of the steel truss and improve the construction efficiency of the underground wall.

[0042] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, and not all of the structures.

[0043] In the description of this invention, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0044] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0045] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention. In addition, the terms "first" and "second" are used only for distinction in description and have no special meaning.

[0046] like Figure 1 and Figure 2 As shown, a water-stop screw 110 is installed in the underground wall, and the water-stop plate 120 on the water-stop screw 110 can prevent groundwater from seeping into the inner side of the underground wall.

[0047] Example 1

[0048] like Figure 3 and Figure 4 As shown, this embodiment provides a steel truss 210 that blocks the seepage path of groundwater at the underground wall, improving the waterproofing effect and the construction efficiency of the underground wall.

[0049] See Figure 3 and Figure 4 The steel truss 210 includes two longitudinal steel bars 211 arranged at intervals along the wall thickness direction. The two longitudinal steel bars 211 are connected by multiple connecting steel bars 212. The multiple connecting steel bars 212 are arranged at intervals along the vertical direction. Each longitudinal steel bar 211 is provided with multiple connectors 213 arranged at intervals along the vertical direction. The connectors 213 and the connecting steel bars 212 are arranged off-axis along the wall thickness direction. The connectors 213 can be connected to the formwork 300.

[0050] The steel truss 210 provided in this embodiment, with connecting steel bars 212, can connect two longitudinal steel bars 211 into a whole, improving the integrity of the steel truss 210, enhancing the overall strength of the steel skeleton 200, and ensuring the structural reliability of the underground wall. During the use of the underground wall, groundwater will seep into the inside of the underground wall along the connector 213 located on the outside of the underground wall. The staggered arrangement of the connector 213 and connecting steel bars 212 blocks the seepage path of groundwater within the steel truss 210, thus preventing groundwater from continuing to seep inward. This not only helps reduce the erosion of the steel truss 210 by groundwater but also improves the waterproofing effect of the underground wall. During the construction of the underground wall, the formwork 300 can be directly connected to the connector 213, and there is no need to dismantle the formwork 300 after the concrete is poured. This is not only convenient and quick to operate but also eliminates the need for separate waterproofing treatment after the formwork 300 is removed, thereby significantly improving the construction efficiency of the underground wall. The formwork 300 is connected to the steel truss 210 via multiple connectors 213, which helps improve the stability of the formwork 300 during installation on one side of the steel truss 210 and ensures the reliability of concrete pouring during the construction of the underground wall. Furthermore, once the specifications of the underground wall are determined, the steel truss 210 becomes a standardized component, which helps to accelerate the production rate of the steel truss 210 and improve the construction efficiency of the underground wall.

[0051] Specifically, one end of the connecting steel bar 212 is welded to one of the two longitudinal steel bars 211, and the other end of the connecting steel bar 212 is welded to the other of the two longitudinal steel bars 211.

[0052] Optionally, see Figure 3 and Figure 4 One end of the connector 213 is connected to the longitudinal steel bar 211, and the other end of the connector 213 is provided with a hook 2131. The hook 2131 can be locked onto the formwork 300, realizing the quick connection between the formwork 300 and the connector 213. The operation is convenient and quick, significantly improving the construction efficiency of the underground wall.

[0053] Specifically, the formwork 300 is provided with multiple stiffening ribs, and multiple slots are formed between the stiffening ribs. When it is necessary to pour concrete for the underground wall, the hook 2131 is inserted into the slot, and the formwork 300 and the connector 213 can be quickly connected, thereby completing the installation of the formwork 300 on one side of the steel truss 210.

[0054] For example, the formwork 300 adopts a metal mesh non-removable formwork, such as steel mesh formwork or steel mesh composite formwork, so that the formwork 300 does not need to be dismantled after the concrete is poured, thus improving the construction efficiency of the underground wall.

[0055] In this embodiment, see Figure 3 and Figure 4 The other end of the connector 213 is provided with a groove 2132, the opening of which faces the template 300, and hooks 2131 are provided at both ends of the groove 2132. This design allows multiple connection points to be formed between the connector 213 and the template 300, which helps to improve the reliability of the connection between the connector 213 and the template 300 and ensures the smooth progress of concrete pouring.

[0056] For example, the connector 213 is a sheet structure and is made of steel plate, and the connector 213 is welded to the longitudinal reinforcing bar 211.

[0057] Optionally, see Figure 3 and Figure 4 Each of the two longitudinal reinforcing bars 211 has multiple connectors 213 corresponding one-to-one with the multiple connectors 213 on the other longitudinal reinforcing bar 211, and the height of the connector 213 is the same as the height of the corresponding connector 213. This arrangement allows the multiple connectors 213 on the steel truss 210 to be arranged symmetrically, making the steel truss 210 a symmetrical structure. This not only helps to ensure the uniformity of stress on the steel truss 210 and improve the overall structural stability of the steel truss 210, but also facilitates the standardized production of the steel truss 210 and improves the production and assembly efficiency of the steel truss 210.

[0058] In this embodiment, the number of connectors 213 on the longitudinal steel bars 211 near the outer side of the underground wall is the same as the number of connectors 213 on the longitudinal steel bars 211 near the inner side of the underground wall, and the steel truss 210 is a symmetrical structure along the wall thickness direction.

[0059] Optionally, see Figure 3 and Figure 4 The connecting steel bar 212 is perpendicular to the longitudinal steel bar 211. This arrangement, on the one hand, makes the connecting steel bar 212 and the longitudinal steel bar 211 form a two-dimensional steel truss 210, which helps to improve the overall stability of the steel truss 210; on the other hand, it helps to indirectly improve the shear bearing capacity of the steel truss 210.

[0060] In this embodiment, see Figure 3 and Figure 4 Each of the two longitudinal reinforcing bars 211 has multiple connectors 213 corresponding to multiple connectors 213 on the other longitudinal reinforcing bar 211, and the height of the connector 213 is the same as the height of the corresponding connector 213. The connecting reinforcing bar 212 is perpendicular to the longitudinal reinforcing bar 211. This arrangement helps to further improve the symmetry of the steel truss 210, ensure the uniformity of stress on the steel truss 210 as a whole, and improve the overall structural stability of the steel truss 210.

[0061] Example 2

[0062] like Figure 3 , Figure 4 and Figure 5 As shown, this embodiment provides a reinforcing steel cage 200, including horizontal reinforcing bars 220 and multiple reinforcing steel trusses 210 as described in Embodiment 1. The multiple reinforcing steel trusses 210 are arranged at intervals along the length of the wall, and the horizontal reinforcing bars 220 are connected to the longitudinal reinforcing bars 211 of the multiple reinforcing steel trusses 210. The horizontal reinforcing bars 220 can connect the multiple reinforcing steel trusses 210 into a whole, which helps to improve the integrity of the reinforcing steel cage 200 and ensure the overall reliability of the reinforcing steel cage 200. Furthermore, the horizontal reinforcing bars 220 can also constrain the concrete and longitudinal reinforcing bars 211 to form a composite load-bearing system of "horizontal reinforcing bars 220-concrete-longitudinal reinforcing bars 211", significantly improving the shear strength of the underground wall.

[0063] For example, the horizontal reinforcing bar 220 and the longitudinal reinforcing bar 211 are connected by binding, or the horizontal reinforcing bar 220 and the longitudinal reinforcing bar 211 are welded together.

[0064] In this embodiment, see Figure 4 and Figure 5Multiple horizontal reinforcing bars 220 are provided, and the number of horizontal reinforcing bars 220 is no greater than the number of connectors 213 on a single longitudinal reinforcing bar 211. Each horizontal reinforcing bar 220 can be connected to the upper surface of any connector 213. The number of connectors 213 is determined according to the specifications of the formwork 300, as long as the formwork 300 can be stably installed on the steel truss 210 via the connectors 213. Therefore, more connectors 213 can be arranged on the longitudinal reinforcing bars 211. The number of horizontal reinforcing bars 220 is determined according to the design requirements of the underground wall. To ensure ease of construction, the number of horizontal reinforcing bars 220 does not need to be too densely arranged; therefore, the number of horizontal reinforcing bars 220 can be no greater than the number of connectors 213 on a single longitudinal reinforcing bar 211. In addition, connectors 213 can be installed according to the position of the horizontal reinforcing bars 220 so that the horizontal reinforcing bars 220 can be connected to the upper surface of the connectors 213, the horizontal reinforcing bars 220 can be supported by the connectors 213, and the connection area between the horizontal reinforcing bars 220 and the steel truss 210 can be expanded, thereby improving the reliability of the connection between the horizontal reinforcing bars 220 and the steel truss 210 and ensuring the overall service life of the steel cage 200.

[0065] For example, the reinforcing steel cage 200 includes a reinforced zone and an unreinforced zone. The spacing between two adjacent horizontal reinforcing bars 220 in the reinforced zone is smaller than the spacing between two adjacent horizontal reinforcing bars 220 in the unreinforced zone. In the reinforced zone, multiple connectors 213 on a longitudinal reinforcing bar 211 correspond one-to-one with multiple horizontal reinforcing bars 220. In the unreinforced zone, only one of two adjacent connectors 213 on a longitudinal reinforcing bar 211 is connected to a horizontal reinforcing bar 220.

[0066] Example 3

[0067] This embodiment provides an underground wall, including a concrete layer and a steel reinforcement cage 200 as described in Embodiment 2. The steel reinforcement cage 200 is located within the concrete layer to form a reinforced concrete underground wall. The steel reinforcement cage 200 provides tensile strength to the underground wall as a whole, while the concrete provides compressive strength. These complementary strengths give the underground wall extremely high load-bearing capacity.

[0068] Example 4

[0069] like Figure 6 and Figure 7 As shown, this embodiment provides a construction process for an underground wall, applicable to the underground wall of Embodiment 3, including the following steps:

[0070] S1. Using steel bar processing equipment, connect multiple connecting steel bars 212 to two longitudinal steel bars 211; then, using steel bar processing equipment, process multiple connectors 213 on the longitudinal steel bars 211 to form a steel truss 210.

[0071] In this embodiment, step S1 specifically includes the following steps:

[0072] S11. Determine the first preset spacing between the two longitudinal steel bars 211 according to the thickness of the underground wall, and send the two longitudinal steel bars 211 into the steel bar processing equipment. The steel bar processing equipment adjusts the distance between the two longitudinal steel bars 211 according to the first preset spacing.

[0073] S12. Multiple connecting steel bars 212 are sequentially fed into the steel bar processing equipment according to the second preset spacing. The steel bar processing equipment connects the fed connecting steel bars 212 with two longitudinal steel bars 211.

[0074] Specifically, when multiple connecting steel bars 212 are fed in, the connecting steel bars 212 are made perpendicular to the longitudinal steel bars 211; subsequently, the steel bar processing equipment can automatically weld the fed connecting steel bars 212 to the longitudinal steel bars 211.

[0075] The second preset spacing is determined according to the specific situation of the steel truss 210. As long as multiple connecting steel bars 212 can connect two longitudinal steel bars 211 into a whole, and the subsequent connecting piece 213 can be arranged in a staggered manner with the connecting steel bar 212.

[0076] S13. Using steel bar processing equipment, multiple connectors 213 are processed on the longitudinal steel bars 211 to form a steel truss 210.

[0077] Specifically, multiple galvanized steel sheets are sequentially fed into the rebar processing equipment at a third preset interval. During feeding, the extension direction of the galvanized steel sheets must be perpendicular to the longitudinal rebar 211. Subsequently, the rebar processing equipment can automatically weld the fed galvanized steel sheets to the longitudinal rebar 211 and punch grooves 2132 on the galvanized steel sheets to form connectors 213.

[0078] In other embodiments, grooves 2132 are first punched out on galvanized steel plates using external equipment to form connectors 213; then, multiple connectors 213 are sequentially fed into steel bar processing equipment at a second preset interval, and the connectors 213 are welded to longitudinal steel bars 211.

[0079] The third preset spacing is determined according to the specific situation of the steel truss 210 and the formwork 300. As long as the multiple connectors 213 can stably fix the formwork 300 to one side of the steel truss 210, it is sufficient.

[0080] In the above process, step S1 can be performed in the steel bar processing plant, so that the steel truss 210 is a standardized component, which shortens the on-site construction time and improves construction efficiency.

[0081] S2. Using a processing mold, connect the longitudinal steel bars 211 and the horizontal steel bars 220 of multiple steel trusses 210 to form a steel skeleton 200.

[0082] In this embodiment, step S2 specifically includes the following steps:

[0083] S21. Determine the number of steel trusses 210 and the spacing between two adjacent steel trusses 210 according to the design requirements of the underground wall.

[0084] S22. Install multiple steel trusses 210 at intervals onto the processing mold table;

[0085] S23. Using a processing mold, the horizontal steel bars 220 are arranged around the outside of multiple steel trusses 210, and the horizontal steel bars 220 are fixedly connected to the longitudinal steel bars 211 of the multiple steel trusses 210.

[0086] S3. Install templates 300 on both the inner and outer sides of the underground wall, and connect the templates 300 to multiple connectors 213 on the corresponding sides.

[0087] Specifically, on the inner side of the underground wall, the hooks 2131 of the multiple connectors 213 on the inner side are all engaged with the stiffening ribs of the inner formwork 300, and the inner formwork 300 is connected to the steel truss 210; on the outer side of the underground wall, the hooks 2131 of the multiple connectors 213 on the outer side are all engaged with the stiffening ribs of the outer formwork 300, and the outer formwork 300 is connected to the steel truss 210.

[0088] S4. Pour concrete.

[0089] Specifically, the concrete pouring process is existing technology in this field and will not be described in detail here.

[0090] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art will be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the claims of the present invention.
