[0033] In conjunction with the accompanying drawings, some embodiments of the present invention are described in detail below. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0034] Example 1

[0035] refer to Figure 1 As shown, an embodiment of the present application provides a cage connection device 100 , which includes a plurality of support assemblies 110 , a plurality of connection assemblies 120 and a cage 130 .

[0036] Specifically, Figures 1 to 3As shown, the support assembly 110 includes a support member 111 and an anchor member 112, the support member 111 is connected to one end of the anchor member 112, and the end of the anchor member 112 away from the support member 111 is inserted into the rock wall, so that a plurality of the support assemblies 110 can form a support platform; each of the connecting assemblies 120 is connected to the support member 111; the ladder cage 130 is arranged on the support platform, and the bottom of the ladder cage 130 is arranged between two adjacent connecting assemblies 120, accordingly, the ladder cage connection The device 100 can be used for connecting and installing a ladder cage 130 under a support beam. The support member 111 is fixed to the side wall of the foundation pit through an anchor member 112. The ladder cage 130 is installed on a support platform through a connecting assembly 120. The supporting platform can support and support the bottom of the ladder cage 130. It has a compact structure and high space utilization. The bottom of the ladder cage 130 is arranged between two adjacent connecting assemblies 120, so that the two adjacent connecting assemblies 120 limit the ladder cage 130, and the ladder cage 130 under the support beam can be installed more stably.

[0037] It should be noted that a plurality of support assemblies 110 can constitute a support platform, that is, a plurality of support assemblies 110 are at the same horizontal height, and a plurality of support assemblies 110 cooperate with each other to form a support platform to support and install the ladder cage 130 .

[0038] like Figure 1 and Figure 4 As shown, the cage connection device 100 has a first direction. Exemplarily, the first direction is taken as the height direction of the cage connection device 100. It can be understood that the above definition is only for the convenience of understanding the relative position relationship of each part in the cage connection device 100, and should not be understood as a limitation to the present application.

[0039] In one embodiment, optionally, Figure 2 and Figure 3 As shown, the number of the support members 111 is at least two, and the two support members 111 are located on opposite sides of the cage 130 along the first direction, referring to Figure 4 As shown, each support member 111 corresponds to at least two anchor members 112, and the two anchor members 112 are located at opposite ends of the support member 111 along the first direction. Accordingly, at least two anchor members 112 are used to connect and fix the support member 111 to achieve the purpose of installing the support member 111. It can be understood that an anchor is a load-bearing member that penetrates into a stable soil layer or rock layer, and improves the stability of the structure by transferring the load to the deep soil or rock.

[0040] In one embodiment, optionally, reference Figure 5 and Figure 6As shown, the support assembly 110 also includes a pad 113, which abuts between the support member 111 and the anchor member 112. The pad 113 is used to bear and support the support member 111 and the anchor member 112. The pad 113 has the effect of dispersing pressure, which can not only increase the contact area, reduce the pressure concentration of the anchor or connecting parts on the surface of the structure, and prevent local crushing or damage, but the anchor member 112 and the pad 113 can work together to avoid direct friction with the surface of the support member 111, reduce damage, and prevent corrosion.

[0041] In one embodiment, optionally, in combination Figure 2 and Figure 3 As shown, the connection assembly 120 includes a plurality of connection members 121 , and one connection member 121 is respectively disposed at the four corners of the bottom of the elevator cage 130 , and the elevator cage 130 is mounted and fixed on the support member 111 through the connection members 121 .

[0042] Optionally, refer to Figure 3 As shown, the bottom of the ladder cage 130 is connected to the side of the connecting member 121 away from the supporting member 111, and the ladder cage 130 is installed and fixed by the connecting member 121, that is, the connecting member 121 is arranged between the ladder cage 130 and the supporting member 111.

[0043] Further, the connecting member 121 is an angle iron, and the angle iron is clamped with the bottom position of the ladder cage 130. It can be understood that the connecting member 121 is an angle iron, which is also called angle steel or L-shaped steel. The angle iron has a certain cross-sectional shape and size. Because its cross section is a 90-degree right angle shape, the bottom position of the ladder cage 130 is clamped and fixed by the right-angle structure of the angle iron.

[0044] In summary, the ladder cage connection device 100 can be used for the connection and installation of the ladder cage 130 under the support beam. The support member 111 is fixed to the side wall of the foundation pit through the anchor member 112. The ladder cage 130 is installed on the support platform through the connection component 120. The support platform can support and support the bottom of the ladder cage 130. The bottom of the ladder cage 130 is arranged between two adjacent connection components 120, so that the two adjacent connection components 120 limit the ladder cage 130. The ladder cage 130 under the support beam can be installed more stably, with a compact structure and high space utilization, which reduces obstacles and impacts on the construction process in the foundation pit.

[0045] Example 2

[0046] refer to Figures 1 to 3 As shown, an embodiment of the present application provides another cage connection device 100 , which includes a plurality of support assemblies 110 , a plurality of connection assemblies 120 and a cage 130 .

[0047] Specifically, Figures 1 to 3 As shown, the support assembly 110 includes a support member 111 and an anchor member 112, the support member 111 is connected to one end of the anchor member 112, and one end of the anchor member 112 away from the support member 111 is inserted into the rock wall, so that a plurality of the support assemblies 110 can form a support platform, and the ladder cage connecting device 100 can be used for connecting and installing the ladder cage 130 under the support beam, the support member 111 is fixed to the side wall of the foundation pit through the anchor member 112, and the ladder cage 130 is installed on the support platform through the connecting assembly 120, and the support platform can support and support the bottom of the ladder cage 130, and has a compact structure and high space utilization.

[0048] In this embodiment, each of the connecting components 120 is connected to the support member 111; the ladder cage 130 is arranged on the supporting platform, and the bottom of the ladder cage 130 is arranged between two adjacent connecting components 120. Accordingly, the bottom of the ladder cage 130 is arranged between two adjacent connecting components 120, so that the two adjacent connecting components 120 limit the ladder cage 130, and the ladder cage 130 under the support beam can be installed more stably.

[0049] In one embodiment, optionally, in combination Figure 1 and Figure 4 As shown, the angle between the anchor member 112 and the support member 111 is θ, which satisfies 5°≤θ≤45°, that is, there is a certain angle between the anchor member 112 and the support member 111, and the angle θ is greater than or equal to 5°, so that the anchor member 112 is inserted into the rock wall, and the support member 111 is connected and supported by the anchor member 112, so that the support member 111 can form a support platform, and the angle θ between the anchor member 112 and the support member 111 needs to be less than or equal to 45°, so as to reduce the situation where the angle θ between the anchor member 112 and the support member 111 is too large, causing the anchor member 112 to be inserted into the rock wall at a shallow depth and become loose, thereby affecting the insertion stability of the anchor member 112, thereby improving the connection and support effect of the anchor member 112 on the support member 111. It should be noted that reference Figure 4 As shown, the angle θ is the angle between the anchor member 112 and the horizontal plane. Exemplarily, the angle θ between the anchor member 112 and the support member 111 can be 5°, 15°, 20°, 35°, 40°, 45°. Of course, the angle θ is not limited thereto. In other embodiments, θ can be 8°, 10°, 24°, 44°, which will not be listed here.

[0050] like Figure 1 and Figure 4 As shown, the cage connection device 100 has a first direction. Exemplarily, the first direction is taken as the height direction of the cage connection device 100.

[0051] In one embodiment, optionally, Figure 2 and Figure 3 As shown, the number of the support members 111 is at least two, and the two support members 111 are located on opposite sides of the cage 130 along the first direction, referring to Figure 4 As shown, each support member 111 corresponds to at least two anchor members 112, and the two anchor members 112 are located at opposite ends of the support member 111 along the first direction. Accordingly, at least two anchor members 112 are used to connect and fix the support member 111, so as to achieve the purpose of installing the support member 111. It can be understood that an anchor is a load-bearing member that penetrates into a stable soil or rock layer, and improves the stability of the structure by transferring the load to the deep soil or rock. For example, the anchor member 112 can be a chemical anchor, and the anchor member 112 is fixed in the hole by a resin adhesive. The anchor member 112 can also be a rock anchor, and the anchor member 112 is directly anchored in the rock.

[0052] Further, refer to Figure 5 and Figure 6 As shown, the four anchor members 112 correspond to one support member 111, and the four anchor members 112 are respectively arranged at the four corners of one side of the support member 111. The strong anchoring force of the anchor members 112 is utilized to enable the cage connection device 100 to be installed and fixed, thereby reducing the safety risk of insufficiently tight connection and having better stability.

[0053] In one embodiment, optionally, reference Figure 5 and Figure 6 As shown, the support assembly 110 also includes a pad 113, which is abutted between the support member 111 and the anchor member 112. The pad 113 is used to bear and support the support member 111 and the anchor member 112. The pad 113 has the effect of dispersing pressure, which can not only increase the contact area, reduce the pressure concentration of the anchor or connecting parts on the surface of the structure, and prevent local crushing or damage, but the anchor member 112 and the pad 113 can work together to avoid direct friction with the surface of the support member 111, reduce damage, and also prevent corrosion. Demonstratively, the pad 113 is a square metal sheet or a flat metal sheet.

[0054] Alternatively, if Figure 4As shown, the support member 111 is a triangular bracket, which utilizes the stability property of a triangle in geometry, because after its three sides are fixed, the length change of any side will cause the change of the other two sides and the angle, thereby resisting external forces and keeping the overall shape unchanged. Therefore, the triangular bracket has better stability, lightness and adaptability, effectively dispersing the load of the ladder cage 130 and preventing the structure from overturning. Exemplarily, the triangular bracket is made of channel steel.

[0055] In one embodiment, optionally, in combination Figure 2 and Figure 3 As shown, the connection assembly 120 includes a plurality of connection members 121 , and one connection member 121 is respectively disposed at the four corners of the bottom of the elevator cage 130 , and the elevator cage 130 is mounted and fixed on the support member 111 through the connection members 121 .

[0056] Optionally, refer to Figure 3 As shown, the bottom of the ladder cage 130 is connected to the side of the connecting member 121 away from the support member 111, and the ladder cage 130 is installed and fixed by the connecting member 121, that is, the connecting member 121 is arranged between the ladder cage 130 and the support member 111. Exemplarily, the connecting member 121 and the ladder cage 130 can be connected by welding, and the ladder cage 130 and the support member 111 can be connected by welding.

[0057] Further, the connecting member 121 is an angle iron, and the angle iron is clamped with the bottom position of the ladder cage 130. The connecting member 121 is an angle iron, and the bottom position of the ladder cage 130 is clamped and fixed by the right-angle structure of the angle iron.

The foundation pit installation structure has all the beneficial effects of the ladder cage connection device 100, which will not be described in detail here.

[0060] In all examples shown and described herein, any specific values ​​should be interpreted as merely exemplary and not as limiting, and thus other examples of the exemplary embodiments may have different values.

[0061] The above-mentioned embodiments only express several implementation methods of the present invention, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention.
