Description

Technical Field

[0001] The present application relates to the field of building construction, and in particular to a corbel device and a construction method thereof. Background Art

[0002] Steel sheet piles have become the preferred solution for foundation pit support projects due to their outstanding advantages such as stable quality, convenient construction, maintenance-free and recyclable. However, in deep foundation pit engineering applications, the traditional welded bracket process has several technical defects that need to be addressed: First, under the multi-channel support system, the corbels need to be welded in layers and the surrounding purlins need to be erected. However, due to factors such as the small working space and soil contamination on the pile surface, the welding quality is difficult to effectively control. Second, the on-site welding operation lacks real-time quality inspection methods, resulting in insufficient weld strength, which can easily cause the corbels to deform or even break, thereby endangering the overall stability of the support system. Third, the welding of corbels is time-consuming, which significantly reduces the construction efficiency when using steel sheet piles for support and directly affects the progress of the project. Fourth, conventional foundation pit monitoring methods are not timely enough and mainly rely on manual regular measurements. They cannot capture sudden deformations in a timely manner, and the labor cost of long-term projects far exceeds the investment in automated equipment. In addition, monitoring operations are difficult to carry out under harsh working conditions such as heavy rain and at night, posing a significant safety hazard. Finally, after the foundation pit project is completed, the corbels need to be cut to dismantle, and the steel sheet piles need to be re-welded for recycling. This process will damage the material properties of the steel sheet piles and shorten their service life.

[0024] Example 1 See also Figure 1 This embodiment is applicable to foundation pit support, and the foundation pit support system includes steel sheet piles 20, corbel devices 10, purlins 30 and support beams.

[0025] See also Figure 1 and Figure 2 This embodiment provides a corbel device 10 , which includes a suspension assembly 100 , a support assembly 200 and an inclination angle collector 300 .

[0026] The suspension assembly 100 is composed of a U-shaped member 110 , a first connecting member 120 , a second connecting member 130 and a vertical plate 140 .

[0027] See also Figure 3 The U-shaped member 110 includes a first end and a second end. In this embodiment, the U-shaped member 110 is composed of an arc-shaped portion 111 and two straight portions 112. The two straight portions 112 are respectively located at the two ends of the arc-shaped portion 111, that is, the two straight portions 112 are respectively the first end and the second end mentioned above. In this embodiment, the first end is open and the second end is closed.

[0028] The first connecting member 120 and the second connecting member 130 are disposed opposite to each other at the first end, and the first connecting member 120 is located on a side of the second connecting member 130 away from the second end.

[0029] The first connecting member 120 and the second connecting member 130 are welded to the inner wall of the first end, or the first connecting member 120 and the second connecting member 130 are welded to the outer wall of the first end, or the first connecting member 120 and the second connecting member 130 are welded to the end portion of the first end.

[0030] In this embodiment, the first connecting member 120 and the second connecting member 130 are both steel plates, and the first connecting member 120 and the second connecting member 130 have the same shape and size, that is, the first connecting member 120 and the second connecting member 130 are axially symmetrically arranged along the center line of the straight portion 112.

[0031] The first connecting member 120 and the second connecting member 130 are both provided with multiple groups of through holes. The multiple through holes in each group are arranged at intervals along the center line of the straight portion 112. Each through hole passes through the first connecting member 120 and the second connecting member 130 perpendicular to the center line of the straight portion 112.

[0032] Please continue reading Figures 1 to 3 The vertical plate 140 is placed between the first connecting member 120 and the second connecting member 130, and the vertical plate 140 is fixedly connected to the first connecting member 120 and the second connecting member 130 through the first fastener 150. In this embodiment, it can be set that the vertical plate 140 is provided with the same number of connecting holes as the first connecting member 120 and the connecting holes are one-to-one corresponding. The connecting holes are through-through arranged in the vertical plate 140, and the first fastener 150 includes a bolt and a nut. The bolt is inserted into the through hole from the side of the second connecting member 130 away from the first connecting member 120, and after passing through the connecting hole, it is inserted from the side of the first connecting member 120, and the nut locks the bolt on the side of the first connecting member 120 away from the second connecting member 130.

[0033] The number of first fasteners 150 is multiple groups, each group includes multiple first fasteners 150, and the number of first fasteners 150 in each group is less than or equal to the number of through holes in each group. It can be understood that one through hole in each group can match one first fastener 150. During actual assembly, at least one through hole in each group matches one first fastener 150 to play a fixed connection role, and the remaining through holes can be installed with the first fasteners 150 or not.

[0034] This embodiment uses a group of five through holes as an example for illustration. The vertical plate 140 is inserted from the end of the first connecting member 120 and the second connecting member 130 away from the first end. The length of the insertion of the vertical plate 140 is defined as the insertion depth. When inserted to the first end, it is the maximum insertion depth of the vertical plate 140. At this time, the five through holes all match the first fastener 150. The vertical plate 140 moves one unit distance (the distance between the two through holes) in the direction away from the first end, which is a reduction of one unit of insertion depth. At this time, the through hole closest to the first end is not installed with the first fastener 150, and the remaining four through holes are each installed with a first fastener 150, and so on, thereby realizing the vertical distance H adjustment of the bracket device 10.

[0035] See also Figure 1 After the first fastener 150 is installed, the plane where the nut is located constitutes the first supporting surface, and the surface of the straight portion 112 facing the first supporting surface is the second supporting surface. The second supporting surface and the first supporting surface match the steel sheet pile 20 and serve as the supporting position of the corbel device 10.

[0036] See also Figures 1 to 3 The support assembly 200 is composed of a horizontal plate 210, a first mounting member 220, a second mounting member 230, a third mounting member 240, a fourth mounting member 250, and an inclined rod 260. The first mounting member 220, the second mounting member 230, the third mounting member 240, and the fourth mounting member 250 are all made of steel plates, and the first mounting member 220 and the second mounting member 230 have the same shape and size, and the third mounting member 240 and the fourth mounting member 250 have the same shape and size.

[0037] In some other embodiments, the shapes and sizes of the first mounting member 220 , the second mounting member 230 , the third mounting member 240 , and the fourth mounting member 250 may be set to be the same, so as to enable batch production and assembly and reduce construction costs.

[0038] The horizontal plate 210 and the vertical plate 140 are arranged vertically, that is, the angle between the horizontal plate 210 and the vertical plate 140 is a right angle. The right-angle design makes this embodiment have a stable structure. In order to improve the stability of this embodiment, welding can also be performed at the connection position of the horizontal plate 210 and the vertical plate 140.

[0039] The first mounting member 220 is arranged on the upper surface of the horizontal plate 210, the second mounting member 230 is arranged on the lower surface of the horizontal plate 210, and the horizontal plate 210 is fixedly connected to the first mounting member 220 and the second mounting member 230 by the second fastener 160, the third mounting member 240 and the first connecting member 120 are located on the same side of the vertical plate 140, the fourth mounting member 250 and the second connecting member 130 are located on the same side, and the vertical plate 140 is fixedly connected to the third mounting member 240 and the fourth mounting member 250 by the third fastener 170.

[0040] Similar to the first connecting member 120, the second connecting member 130 and the vertical plate 140, the distance between the first mounting member 220 and the vertical plate 140 is adjustable. When the position of the first mounting member 220 is determined, the second mounting member 230 is set back to the first mounting member 220. Since the length of the diagonal rod 260 is fixed, the position of the third mounting member 240 can be determined according to the position of the first mounting member 220. The fourth mounting member 250 is set back to the third mounting member 240, thereby realizing the adjustment of the lateral distance L of the bracket device 10.

[0041] The diagonal rod 260 is hinged to the second mounting member 230 and the third mounting member 240 respectively, and the diagonal rod 260, the vertical plate 140 and the horizontal plate 210 jointly define a support space. The cross-section of the support space is a right triangle. It can be understood that the right triangle has good stability and is not prone to tilting, thereby extending the service life of this embodiment.

[0042] See also Figure 5 and Figure 6 The second mounting member 230 includes a main body 231 and two sleeves 232. The two sleeves 232 are arranged on the main body 231 at intervals. The inclined rod 260 includes a rod body 261 and a hinge shaft 262. The hinge shaft 262 is located at one end of the rod body 261. The hinge shaft 262 is placed in the sleeve 232 to realize the hinge connection between the inclined rod 260 and the second mounting member 230.

[0043] Please continue reading Figures 1 to 3 The hinge between the third mounting member 240 and the oblique rod 260 is similar to the above hinge, and will not be described again here.

[0044] The tilt angle collector 300 is mounted on the vertical plate 140 and is located within the support space. The tilt angle collector 300 of this embodiment is used to collect tilt angles, which represent the degree of tilt of an object relative to a horizontal plane and are typically expressed in degrees.

[0045] When the inclination angle collected by the inclination angle collector 300 is greater than a preset value, it indicates that the deformation of the corbel has reached a dangerous value and the corbel device 10 needs to be replaced to ensure the stability of the support system.

[0046] The inclination angle collector 300 used in this embodiment is a LoRa high-precision inclination angle collector. This LoRa high-precision inclination angle collector automatically collects the device's inclination angle and wirelessly transmits the data to a backend server. By setting an inclination angle change threshold on the backend server, a text message or audio and visual alarm is automatically triggered. This device can remotely monitor the inclination changes of the steel sheet piles 20, understand the dynamic changes of the support structure during construction, and ensure the safety and stability of the foundation pit project.

[0047] The corbel assembly 10 further includes a stopper 270 mounted on the first mounting member 220. When the purlin 30 becomes loose, it can easily slide off the side of the horizontal plate 210 away from the vertical plate 140 and fall, posing a risk to the safety of construction workers. In this embodiment, the stopper 270 limits the displacement of the purlin 30, thereby protecting the safety of construction workers.

[0048] Based on the above content, the above-mentioned bracket device 10 is used. In this embodiment, the construction method of the bracket device 10 is further described as follows: S100 . Hinging one end of the oblique rod 260 to the second mounting member 230 , and hinging the other end of the oblique rod 260 to the third mounting member 240 .

[0049] See also Figure 2 、 Figure 5 and Figure 6 The hinged installation of the oblique rod 260 and the second mounting member 230 includes: welding two sleeves 232 on the second mounting member 230 at intervals, and placing a hinge shaft 262 of the oblique rod 260 in the two sleeves 232.

[0050] Similarly, the diagonal rod 260 is hingedly mounted to the fourth mounting member 250 .

[0051] Please continue reading Figures 1 to 3 .

[0052] S200. According to the preset size of the purlin 30, determine the installation position of the first mounting member 220 on the transverse plate 210, then place the first mounting member 220 on the upper surface of the transverse plate 210, place the second mounting member 230 on the lower surface of the transverse plate 210 corresponding to the first mounting member 220, and then lock the second fastener 160 to fix the transverse plate 210, the first mounting member 220, and the second mounting member 230.

[0053] In this embodiment, according to different widths of the purlin 30 , the installation position of the first installation member 220 and the installation position of the second installation member 230 are adapted to the width of the purlin 30 .

[0054] The installation position of the third installation member 240 is determined according to the installation position of the second installation member 230 .

[0055] S300 . Weld the limiting member 270 to the upper surface of the first mounting member 220 .

[0056] S400 . Install the inclination angle collector 300 on the vertical plate 140 .

[0057] S500. Place the horizontal plate 210 with the inclined rod 260 vertically on the side of the vertical plate 140 equipped with the inclination collector 300, rotate the inclined rod 260 so that the third mounting member 240 is in contact with the vertical plate 140, place the fourth mounting member 250 on the other side of the vertical plate 140, and then lock the third fastener 170 to fix the vertical plate 140, the third mounting member 240, and the fourth mounting member 250.

[0058] S600 . Weld the first connecting member 120 and the second connecting member 130 to the same end of the U-shaped member 110 , and then insert the pre-assembled riser 140 between the first connecting member 120 and the second connecting member 130 .

[0059] S700. According to the preset height of the purlin 30, the insertion depth of the vertical plate 140 is adjusted, and then the first fastener 150 is locked, so that the vertical plate 140, the first connecting member 120 and the second connecting member 130 are fixed to obtain the corbel device 10.

[0060] In this embodiment, the vertical distance H is adjusted to ensure that after the vertical plate 140 is fixed, the distance from the first connecting member 120 to the horizontal plate 210 (i.e., the vertical distance H) is greater than or equal to the height of the surrounding purlin 30. In this embodiment, the horizontal distance L is adjusted to ensure that the distance from the first mounting member 220 to the vertical plate 140 (i.e., the horizontal distance L) is greater than the width of the surrounding purlin 30.

[0061] This embodiment is applicable to foundation pit supports of different depths and is suitable for purlins 30 of different sizes.

[0062] S800 . Hang the corbel device 10 on the steel sheet pile 20 , and lay the purlin 30 on the transverse plate 210 .

[0063] See also Figure 2 and Figure 4 In this embodiment, the steel sheet pile 20 is a steel plate, and the corbel device 10 is hung on the steel sheet pile 20. The top edge of the steel sheet pile 20 abuts against the connection between the straight portion 112 and the arc portion 111, and the side surface of the steel sheet pile 20 abuts against the first supporting surface and the second supporting surface of the U-shaped member 110, thereby ensuring the stability of the corbel device 10 suspended on the steel sheet pile 20.

[0064] Please continue reading Figures 1 to 3 After the construction of purlin 30 is completed, the subsequent support beam construction and foundation pit backfilling will continue.

[0065] S900. After dismantling the purlin 30, remove the corbel device 10.

[0066] For ease of description and understanding, this embodiment defines the position of the first fastener 150, the position of the second fastener 160, and the position of the third fastener 170 as the first fastening node, the second fastening node, and the third fastening node, respectively. When the bracket device 10 is used for the first time, it needs to go through the assembly steps S100-S800 and be removed after use. When it is used next time, only the first fastening node, the second fastening node, and the third fastening node need to be adjusted. The operation is simple and quick, which improves construction efficiency.

[0067] Of course, for the convenience of storage, all components may be disconnected after the first use, and steps S100-S900 may be repeated for the next use.

[0068] Therefore, all components of this embodiment can be disassembled and reassembled, have good turnover, can be recycled, and save construction material consumption.

[0069] In addition, after the construction of the foundation pit project is completed, the corbel device 10 can be removed by simply pulling up the U-shaped member 110 hanging on the steel sheet pile 20. Therefore, the steel sheet pile 20 and the corbel device 10 are connected in the form of a hanging connection. After disassembly, the structure of the steel sheet pile 20 and the corbel device 10 will not be damaged. During the subsequent turnover use, the material properties of the steel sheet pile 20 and the corbel device 10 will not be damaged, thereby extending the service life.

[0070] The completion of the above-mentioned foundation pit construction refers to the backfilling of the foundation pit to the specified height. The demolition process of this embodiment is simple, and rapid support and rapid demolition and evacuation are achieved, which shortens the construction time and avoids the extension of the construction period and material loss caused by welding and cutting of the brackets.
