Description

Technical Field

[0001] This application relates to the field of building construction technology, and in particular to a floor slab support device. Background Technology

[0002] With the advancement of social productivity, human demand for architectural space continues to grow. The reverse construction method is increasingly widely used in dense urban foundation pits. As the core technology of the reverse construction method, pile-and-column construction has always been a difficult point and a key focus of technical research. In particular, controlling the verticality of the steel pipe column in pile-and-column construction is of paramount importance. However, errors are difficult to avoid during steel pipe column construction. Once a large deviation in verticality occurs, the entire steel pipe column must be replaced layer by layer; otherwise, the functionality and safety of the structure will be severely affected. Because the entire steel pipe column is replaced layer by layer, supporting structures are needed to support the beams and slabs, resulting in large construction loads and high construction risks. Therefore, the accuracy, stability, and reliability of the beam and slab support structure are crucial in the steel pipe column replacement project. If the support device is substandard, it may cause irreversible damage to the floor structure.

[0003] The commonly used support device in current engineering is to use a support steel pipe in conjunction with a jack. The jack is installed on top of the support steel pipe to support the top beam and slab, and the support steel pipe abuts against the bottom floor slab. However, this will make it difficult to apply force to the jack and install and disassemble the jack, which may damage the floor structure. Utility Model Content

[0004] To address the issue of replacing steel pipe columns in the prior art, this application provides a floor slab support device.

[0005] This application provides a floor slab support device, which adopts the following technical solution:

[0006] A floor slab support device includes a support structure for providing support force to a beam slab. The top of the support structure abuts against the beam slab, and the bottom of the support structure is provided with a jack for providing support force. When the force applied by the jack reaches a predetermined value, a support space is formed between the support structure and the bottom floor slab. At this time, high-strength grout is filled into the support space to form a support layer. The support layer provides support force to the support structure, replacing the force applied by the jack to the support structure.

[0007] By adopting the above technical solution, the bottom of the jack is supported by a steel pipe, which avoids the problem of difficult installation and disassembly caused by setting the jack on the top of the supporting steel pipe in the traditional method. When the force applied by the jack reaches the predetermined value, the support space is formed and then filled with high-strength grout to replace the support of the jack, thereby realizing convenient load replacement and easy installation and disassembly of the jack.

[0008] Preferably, the support structure includes a vertically arranged support steel pipe, the top of which abuts against the beam plate, and a support leg is provided on the bottom side of the support steel pipe, which abuts against the jack.

[0009] By adopting the above technical solution, the jacks are installed around the support space, reducing the interference of the formed support layer on the jacks and facilitating the installation and disassembly of the jacks.

[0010] Preferably, a first pad is provided between the supporting steel pipe and the bottom floor slab, the first pad is fixedly connected to the supporting steel pipe, and the supporting space is located between the first pad and the bottom floor slab.

[0011] By adopting the above technical solution, the setting of the first pad increases the contact area between the supporting steel pipe and the supporting layer, making the supporting steel pipe more stable when supported.

[0012] Preferably, the bottom floor slab is provided with positioning bolts and positioning nuts for positioning, and the first pad is provided with positioning holes that cooperate with the positioning bolts; when the force applied by the jack reaches a predetermined value, the nuts are tightened.

[0013] By adopting the above technical solution, the cooperation between the positioning bolts, positioning nuts and positioning holes strengthens the overturning resistance of the support structure.

[0014] Preferably, a steel beam is also provided between the supporting steel pipe and the beam plate, the steel beam is fixedly connected to the beam plate, and the top end of the supporting steel pipe forms an abutting fit with the steel beam.

[0015] By adopting the above technical solution, the steel beam can increase the contact area with the beam slab, provide more stable support, and avoid the problem of damage to the beam slab that may be caused by excessive pressure at a single point.

[0016] Preferably, a second pad is provided between the jack and the bottom floor slab.

[0017] By adopting the above technical solution, the stable operation of the jacks can be ensured, the contact area between the jacks and the bottom floor slab can be increased, and damage to the bottom floor slab can be reduced.

[0018] Preferably, multiple supporting steel pipes are provided, and reinforcing rods are provided between the multiple supporting steel pipes.

[0019] By adopting the above technical solution, the multiple supporting steel pipes can improve the load-bearing capacity of the overall support structure, while the reinforcing rods can enhance the structural integrity between the multiple supporting steel pipes, further improving stability and load-bearing capacity.

[0020] Preferably, a reinforcing plate is also provided on the supporting steel pipe. The reinforcing plate is fixedly connected to the upper side of the supporting steel pipe, and both the reinforcing plate and the supporting steel pipe form an abutting fit with the beam plate.

[0021] By adopting the above technical solution, the reinforcing plate is fixedly connected to the upper side of the supporting steel pipe. Both the reinforcing plate and the supporting steel pipe form an abutment fit with the beam plate. The setting of the reinforcing plate can further improve the lateral stability of the supporting steel pipe and prevent it from tilting or deforming during use.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] 1. Setting up jacks and support space, and installing outriggers on the support steel pipes, and filling the support space with a support layer can facilitate the installation of the support structure. After the support layer is formed, the load of the jacks can be transferred to the support layer, which facilitates the disassembly of the jacks.

[0024] 2. The first and second pads increase the bearing area of ​​the jack and support device, making the structure more uniformly stressed and improving the stability of the support device. Attached Figure Description

[0029] The following is in conjunction with the appendix Figure 1 - Appendix Figure 3 This application will be described in further detail.

[0030] This application discloses a floor slab support device.

[0031] Example 1

[0032] Reference Figure 1 and Figure 2A floor slab support device includes a support structure 1 for providing support to beams and slabs. The top of the support structure 1 forms an abutment fit with the beams and slabs, and the bottom of the support structure 1 is provided with a jack 2 for providing support. When the load applied by the jack 2 reaches a predetermined value, a certain gap will be formed between the support structure 1 and the bottom floor slab. This gap is the support space 3. The support space 3 is filled with high-strength grout. Over time, the grout will form a solid support layer. The support layer can effectively replace the jack 2 and continuously and stably apply load to the support structure 1.

[0033] Reference Figure 1 and Figure 3 The support structure 1 includes a support steel pipe 11. A first pad 5 is provided between the support steel pipe 11 and the bottom floor slab. The first pad 5 is fixedly connected to the bottom surface of the support steel pipe 11. The support space 3 is located between the first pad 5 and the support steel pipe 11. The bottom floor slab is provided with positioning bolts 41 and positioning nuts 42 for positioning. The first pad 5 is also provided with positioning holes that cooperate with the positioning bolts 41. When the force applied by the jack 2 reaches a predetermined value, the positioning nuts 42 are tightened, which strengthens the overturning resistance of the support steel pipe 11.

[0034] Reference Figure 1 and Figure 3 The bottom side of the supporting steel pipe 11 is provided with a support leg 12, which forms an abutment fit with the jack 2. A second pad 6 is also provided between the jack 2 and the bottom floor slab. The design of the support leg 12 allows the jack 2 to be installed around the supporting space 3, reducing the interference of the formed supporting layer on the jack 2, facilitating the installation and disassembly of the jack 2. The second pad 6 ensures the stable operation of the jack 2, increases the contact area between the jack 2 and the bottom floor slab, and reduces damage to the bottom floor slab.

[0035] Reference Figure 1 and Figure 3 A reinforcing plate 13 is also provided on the supporting steel pipe 11. The reinforcing plate 13 is fixedly connected to the top side of the supporting steel pipe 11, and the upper end surface of the reinforcing plate 13 and the top surface of the supporting steel beam 8 are in abutting fit with the beam plate. The setting of the reinforcing plate 13 can further improve the lateral stability of the supporting steel pipe 11 and prevent it from tilting or deforming during use.

[0036] Reference Figure 1 and Figure 3 The support structure 1 is configured with multiple supports, and a reinforcing rod 7 is provided between adjacent support steel pipes 11. The multiple support steel pipes 11 can improve the overall load-bearing capacity of the support structure 1, while the reinforcing rod 7 can enhance the structural integrity between the multiple support steel pipes 11, further improving stability and load-bearing capacity.

[0037] The construction steps are as follows: Determine the location of the beams and slabs that need support, install positioning bolts 41, check the structure and load-bearing capacity of the beams and slabs to ensure construction safety, and at the same time, prepare the necessary materials and tools such as support steel pipes 11, jacks 2, and high-strength grouting material. Fix the first pad 5 to the support steel pipe 11. Then, install the support leg 12 at the bottom of the support steel pipe 11, ensuring that the support leg 12 can form abutment fit with the jack 2. Then, start to vertically install the support steel pipe 11, match the positioning hole on the first pad 5 with the positioning bolts 41 on the bottom floor slab, install the jack 2, and form abutment fit between the jack 2 and the support leg 12. Adjust the load of the jack 2 until it reaches the predetermined value. At this time, tighten the positioning nut 42. A support space 3 is formed between the first pad 5 and the bottom floor slab. Pour the high-strength grouting material into the support space 3. Wait for the high-strength grouting material to solidify into a support layer. After it can fully provide the load, remove the jack 2.

[0038] The implementation principle of this application embodiment is as follows: through the design of the support structure 1, especially the coordinated use of the support steel pipe 11, the pad plate and the jack 2, stable support for the beam and slab is achieved, and the support force can be precisely adjusted according to construction needs; through the use of the positioning bolt 41 and the positioning nut 42, the support structure 1 is precisely fixed, further enhancing its stability; the connection of the reinforcing rod 7 forms a stable frame structure, improving the integrity between multiple support steel pipes 11, so that the support device can remain stable when facing complex loads.

[0039] Example 2

[0040] Reference Figure 1 The difference between this embodiment and Embodiment 1 is that a steel beam 8 is also provided between the beam plate and the supporting steel pipe 11. The steel beam 8 is fixedly connected to the beam plate by expansion bolts, and the upper end surface of the reinforcing plate 13 and the top surface of the supporting steel pipe 11 are in abutting fit with the steel beam 8.

[0041] The implementation principle of this application embodiment is as follows: Through the design of the support structure 1, especially the coordinated use of the support steel pipe 11, the pad, and the jack 2, stable support for the beam and slab is achieved, and the support force can be precisely adjusted according to construction needs; through the use of positioning bolts 41 and positioning nuts 42, the support structure 1 is precisely fixed, further enhancing its stability; the connection of the reinforcing rod 7 forms a stable frame structure, improving the integrity between multiple support steel pipes 11, enabling the support device to remain stable when facing complex loads; the addition of steel beam 8 effectively expands the support area, better disperses the load, and improves the stability and safety of the support structure 1.

[0042] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application.
