Description

Technical Field

[0001] This application relates to the technical field of building construction, and in particular to a steel support structure with a post-settlement pouring strip. Background Technology

[0002] Because residential buildings require the construction of both underground and above-ground structures, and the construction period for above-ground structures is long and the construction load is large, resulting in greater settlement, the settlement joint between the two structures can only be sealed with concrete after the above-ground structure of the residential building is capped and the settlement has basically stabilized.

[0003] In existing technologies, such as Figure 1 As shown, after the residential building is completed, since the height of the above-ground structure 8 is higher than that of the underground structure 7, the uneven settlement during the settlement process may cause it to tilt or shift horizontally to the side of the underground structure 7, which may affect the stability of the overall structure. Therefore, further improvements are needed. Utility Model Content

[0004] To address the above issues, this application provides a steel support structure with a post-settlement cast strip.

[0005] This application provides a steel support structure for post-settlement casting strips, which adopts the following technical solution:

[0006] A steel support structure for a settlement-relief strip includes a support member disposed in the settlement strip and reinforcing members disposed at both ends of the support member. The support member is supported on water-stop steel plates on both sides of the settlement strip, and the two reinforcing members are respectively embedded in the concrete on both sides of the settlement strip.

[0007] By adopting the above technical solution, the support components are erected on the waterstop steel plates on both sides of the post-cast strip, and the reinforcing members connected to both ends of the support components are pre-embedded in the concrete on both sides of the post-cast strip. After the concrete on both sides is poured, the support components are embedded in the post-cast strip, forming a rigid support for the concrete on both sides, providing stable support for the post-cast strip, so as to effectively transmit pressure during uneven settlement, provide certain support for the above-ground structure, reduce the possibility of the above-ground structure tilting to the underground structure or shifting horizontally due to settlement differences, and enhance the integrity and stability of the structure.

[0008] Preferably, the length of the support member matches the width of the post-cast strip.

[0009] By adopting the above technical solution, the length of the support component matches the width of the post-cast strip, which can ensure that the support structure is accurately installed in the post-cast strip and avoid installation deviation or uneven stress caused by mismatch in length. This allows it to play a stable supporting role in the post-cast strip, effectively resisting the pressure caused by uneven settlement of the structures on both sides, thereby improving the overall stability of the structure.

[0010] Preferably, the reinforcing member includes a horizontal extension that passes through the concrete to connect with the end of the support member.

[0011] By adopting the above technical solution, in which the horizontal extension section passes through the concrete and connects to the end of the support, the connection strength between the horizontal extension section and the concrete on both sides of the post-cast strip can be effectively enhanced.

[0012] Preferably, the reinforcing member further includes a vertical anchoring section, which extends downward or upward and is embedded in the concrete to form an L-shaped or T-shaped anchoring structure.

[0013] By adopting the above-mentioned technical solution, in which the vertical anchoring section extends downward or upward and is embedded in the concrete to form an L-shaped or T-shaped anchoring structure, this structural design further improves the overall stability of the support and ensures that the support structure can reliably transmit pressure under uneven settlement conditions, thereby reducing the possibility of the above-ground structure tilting to the underground structure side.

[0014] Preferably, the reinforcing member further includes a reinforcing section disposed in the vertical anchoring section, the reinforcing section being embedded in concrete, and the reinforcing section being a bent steel bar or a stud.

[0015] By adopting the above-mentioned technical solution, the bent steel bars or studs are pre-embedded in the concrete as reinforcing sections, which can significantly improve the connection strength between the vertical anchoring section and the concrete, and effectively resist the possibility of the above-ground structure tilting to the underground structure side, thereby further increasing the pull-out force and reducing the possibility of structural displacement, tilting or horizontal displacement caused by uneven settlement.

[0016] Preferably, the support member includes an I-beam and steel plates disposed at both ends of the I-beam, and the horizontal extension section is connected to the steel plates.

[0017] By adopting the above technical solution, the I-beam, as the main supporting component, can provide sufficient compressive strength and stability. The steel plates at both ends are connected to the horizontal extension section, which enhances the overall integrity of the structure. This allows the steel support to stably bear the pressure transmitted from both sides before the concrete is completely sealed by the post-pouring strip, and to transfer it to the I-beam, thereby reducing the possibility of the above-ground structure tilting to the underground structure side, and ensuring the safety of the structure and the quality of construction.

[0018] Preferably, a connector is provided between the reinforcing member and the supporting member for detachable connection.

[0019] By adopting the above technical solution, the design of the connectors facilitates not only the installation and disassembly of the steel support structure but also provides convenience when adjustments or replacements of components are needed. This flexibility also extends the service life of the support structure, as damaged parts can be replaced individually without requiring a complete replacement.

[0020] Preferably, the horizontal extension extends through the steel plate, and the connector includes a connecting nut that is threadedly connected to the horizontal extension.

[0021] By adopting the above technical solution, the threaded connection between the connecting nut and the horizontal extension section provides a detachable connection function, which facilitates installation and subsequent maintenance, while improving construction efficiency.

[0022] Preferably, a buffer is provided between the support member and the reinforcing member.

[0023] By adopting the above technical solution, the buffer can effectively alleviate the rigid contact between the support and the reinforcement, and reduce the structural stress concentration caused by uneven settlement.

[0024] Preferably, the support member comprises multiple sections of I-beams, and adjacent I-beams are fixed together by fasteners.

[0025] By adopting the above technical solution, the support is composed of multiple H-beams, and adjacent H-beams are fixed together by fasteners. This design allows the total length of the support to be flexibly adjusted according to actual needs to adapt to different widths of the post-pouring strip.

[0026] In summary, this utility model has the following beneficial effects:

[0027] 1. By setting up support members and reinforcement members at both ends in the post-pouring strip, it can effectively resist the pressure caused by uneven settlement between the above-ground structure and the underground garage, thereby reducing the possibility of the above-ground structure tilting or shifting horizontally due to settlement differences, and enhancing the integrity and stability of the structure.

[0028] 2. The length of the support component matches the width of the post-cast strip, ensuring that the steel support structure is precisely fitted into the post-cast strip, thus enhancing the stability and reliability of the structure;

[0029] 3. The reinforcement and concrete anchorage not only improve compressive strength but also reliably transmit pressure, thereby reducing the possibility of the above-ground structure tilting towards the underground structure. Attached Figure Description

[0038] The following is in conjunction with the appendix Figure 1-7 This application will be described in further detail below.

[0039] This application discloses a steel support structure with a post-settlement cast strip.

[0040] Example 1:

[0041] A steel support structure with a post-settlement casting strip, referring to Figure 2 , Figure 3 Several support structures are spaced apart along the length of the post-cast strip 1. This support structure includes support members 2 positioned between the water-stop steel plates 11 on both sides of the post-cast strip 1, and reinforcing members 3 positioned at both ends of the support members 2. The support members 2 are mounted on the pre-installed water-stop steel plates 11 on both sides of the post-cast strip 1, and the two reinforcing members 3 are respectively embedded in the concrete on both sides of the post-cast strip 1. This structural design not only improves the effective support for the structures on both sides of the post-cast strip 1, but also further enhances the stability of the structure.

[0042] The support component 2 specifically includes an I-beam 21 and steel plates 22 disposed at both ends of the I-beam 21. H-beams can also be used to replace the I-beam 21. The I-beam 21 is preferably made of Q235B material, and its specific dimensions can be adjusted according to actual needs. For example, an HW125*125*6.5*9 specification I-beam 21 with a length of 780mm can be selected. The steel plates 22 can be 145mm*145mm*10mm in size and are welded to the I-beam 21.

[0043] In this embodiment, the reinforcing member 3 is a horizontal extension section 31, which is fixedly connected to the steel plate 22. The horizontal extension section 31 is a reinforcing bar, specifically a grade III threaded steel bar with a diameter of 8mm. Four reinforcing bars of length La are set on each side of the outer side of the steel plate 22 and fixed to the steel plate 22 by pressure submerged arc welding. The function of these reinforcing bars is to enhance the connection strength between the steel plate 22 and the concrete and reduce the possibility of the steel plate 22 falling off due to uneven stress. It should be noted that, for the obstruction of the concrete on both sides of the post-pouring strip 1, steel wire mesh 12 needs to be vertically set on the two water-stop steel plates 11. The reinforcing bars are inserted through the steel wire mesh 12, and the steel wire mesh 12 abuts against the steel plate 22 so that the length of the support member 2 can match the width of the post-pouring strip 1. After the concrete on both sides of the post-pouring strip 1 is constructed, the steel support is just stuck in the post-pouring strip 1.

[0044] The implementation principle of the steel support structure for the post-settlement strip in this application embodiment is as follows: the support member 2 is set on the waterstop steel plate 11 on both sides of the post-settlement strip 1, and the reinforcing member 3 connected to both ends of the support member 2 is pre-embedded in the concrete on both sides of the post-settlement strip 1, so that the support member 2 is embedded in the post-settlement strip 1, forming a rigid support for the concrete on both sides, providing stable support for the post-settlement strip 1. The reinforcing member 3 is connected to the support member 2 and pre-embedded in the concrete on both sides of the post-settlement strip 1, so as to effectively transmit pressure during uneven settlement, provide certain support for the above-ground structure 8, reduce the possibility that the above-ground structure 8 will tilt to one side of the underground structure 7 or shift horizontally due to settlement differences, and enhance the integrity and stability of the structure.

[0045] Example 2:

[0046] Reference Figure 4 The difference from Embodiment 1 is that the reinforcing member 3 also includes a vertical anchoring section 32, which is fixedly connected to the horizontal extension section 31. The vertical anchoring section 32 extends downward or upward and is embedded in the concrete, forming an L-shaped or T-shaped anchoring structure, which not only increases the structure's pull-out resistance but also improves the overall stability. The material of the vertical anchoring section 32 can be high-strength threaded steel bars or flat steel, and the specific shape and size are determined according to actual construction requirements. In this embodiment, an L-shaped anchoring structure is shown. It should be noted that since four steel bars are set on one steel plate 22, different anchoring structures can be selected for demonstration.

[0047] Reference Figure 5 Furthermore, the reinforcing member 3 may also include a reinforcing section 33 disposed in the vertical anchoring section 32. The reinforcing section 33 is embedded in the concrete. The reinforcing section 33 is either a bent steel bar or a stud. The design of the bent steel bar can increase the contact area with the concrete and improve the anchoring strength; while the stud has better shear resistance and is suitable for scenarios that need to withstand large shear forces. The setting of these reinforcing sections 33 makes the entire structure more robust and reliable, and can better resist external pressure. The selection of the reinforcing section 33 is set according to the specific requirements. In this embodiment, a stud is used for demonstration.

[0048] Example 3:

[0049] Reference Figure 6 The difference from Embodiment 1 is that a buffer 4 is provided between the support member 2 and the reinforcing member 3. In this embodiment, the buffer 4 can be a rubber pad or a spring; specifically, a rubber pad is shown. The function of the buffer 4 is to dampen and cushion the impact during uneven settlement, reducing the possibility of structural damage caused by sudden impact forces. The specific installation position of the buffer 4 can be adjusted according to the actual stress conditions, for example, it can be placed at the connection between the support member 2 and the reinforcing member 3, and the thickness of the rubber pad can be selected according to actual needs, for example, between 3mm and 10mm.

[0050] A connector 5 is provided between the reinforcing member 3 and the supporting member 2 for detachable connection. This design makes the connection between the reinforcing member 3 and the supporting member 2 more flexible and facilitates later maintenance and replacement.

[0051] Specifically, the reinforcing bars slide through the steel plate 22 and the waterstop plate. In this embodiment, the connector 5 is specifically a connecting nut threadedly connected to the horizontal extension section 31. Two connecting nuts are provided, one abutting against the steel plate 22 and the other abutting against the waterstop steel plate 11. The material of the connector 5 should have high strength and corrosion resistance to ensure its stability and reliability during long-term use. For example, stainless steel or galvanized steel can be selected, as these materials have good corrosion resistance and can effectively extend the service life of the connector 5.

[0052] Example 4:

[0053] Reference Figure 7The difference from Embodiment 1 is that the support member 2 includes multiple H-beams 21, and adjacent H-beams 21 are fixed together by fasteners 6. The fasteners 6 specifically include a fixing plate 61 for abutting adjacent H-beams 21, a fixing bolt 62 passing through the fixing plate 61, and a fixing nut 63 threadedly connected to the fixing bolt 62. The fixing plate 61 has two surfaces that abut against the two mutually distant surfaces of the two flanges of the H-beams 21, respectively. The fixing bolt 62 passes through the fixing plate 61 and the flanges to be threadedly connected to the fixing nut 63. At least two fixing bolts 62 pass through one fixing plate 61 to fix two adjacent H-beams 21. It should be noted that one fixing bolt 62 can pass through two fixing plates 61 and two flanges, or only one fixing plate 61 and one flange, depending on the requirements. The upper surface of the wing plate has through holes (not shown in the figure) for the fixing bolts 62 to pass through. Several through holes are arranged at intervals along the length of the wing plate, and several through holes are located close to the fixing plate 61.

[0054] When two I-beams 21 are provided, this embodiment can also be combined with embodiment 3. In this case, several through holes can be interconnected to form a strip hole. The movement between the two I-beams 21 and the fixing plate 61 is restricted by the fixing between the reinforcing bars and the connecting nuts.

[0055] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
