Description

Technical Field

[0001] This utility model relates to the field of support and hanger technology, and in particular to a combined snap-fit ​​type tunnel load-bearing support and hanger. Background Technology

[0002] Load-bearing supports are pipe fixing support systems with gravity load as the main load. They are a measure to lay pipes on buildings when pipes and equipment are operating under full gravity load.

[0003] In practice, the number of load-bearing supports used in tunnels is often very large, which leads to an excessively long installation cycle. Traditional tunnel load-bearing supports are often installed by fixing them with screws and nuts. The installation requires positioning and tightening, which results in low installation efficiency. On the other hand, the installation of screws and nuts requires torque verification. If the torque does not meet the requirements or some screws are not tightened, accidents may occur. With tens of thousands of screws in a tunnel, it is inevitable that some screws will be left loose or not tightened.

[0004] To enhance the safety of load-bearing supports and improve installation efficiency, this invention provides a combined snap-fit ​​type tunnel load-bearing support. Utility Model Content

[0005] The main purpose of this utility model is to provide a combined snap-fit ​​tunnel load-bearing support bracket to solve the problems of low installation efficiency and the need for torque verification in the installation of existing tunnel load-bearing support brackets, which are fixed by screws and nuts.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A combined snap-fit ​​tunnel load-bearing support bracket, the tunnel load-bearing support bracket comprising:

[0008] The mounting base is a U-shaped plate, consisting of a base plate and two base side plates. Each of the two base side plates has an L-shaped slot at its upper end. The base plate has at least two sets of hanger mounting holes.

[0009] At least two support hangers, which are U-shaped plates, and one end of each support hanger is inserted into the hanger mounting hole group.

[0010] As a further improvement of this utility model, the mounting hole group of the hanger includes one rectangular hole and two rectangular strip holes, and the rectangular strip holes are located on the lower side of the rectangular hole and are symmetrically distributed on the left and right sides relative to the base plate.

[0011] As a further improvement of this utility model, the support bracket is composed of a bracket base plate and two left and right bracket side plates. The bracket base plate has two U-shaped slots on one side, with the openings facing the left and right sides.

[0012] The side plate of the hanger has two U-shaped slots on one side, and the opening ends of both slots face downwards; a chamfer is provided at the upper corner of the same side end; all four U-shaped slots are provided on the same side end of the support hanger.

[0013] As a further improvement of this utility model, a base plate bending edge is provided on the other side of the hanger base plate.

[0014] As a further improvement of this utility model, the U-shaped plate is made of Q235B material.

[0015] As a further improvement of this utility model, the surface treatment of the load-bearing support is hot-dip galvanizing or color galvanizing.

[0016] As a further improvement of this utility model, a first slot is provided on the upper side of the base plate and a second slot is provided on its lower side, and the first slot and the second slot are arranged normally.

[0017] The beneficial effects of this utility model are as follows: the mounting base and the support hanger are connected by a plug-in method, without the use of traditional screws, bolts, nuts or welding and other auxiliary connections, which makes the installation more efficient and increases the reliability of the connection. The hot-dip galvanizing or color zinc plating surface treatment process greatly increases the service life of each component. At the same time, the advantage of the normal arrangement of the mounting slots is that no matter which direction the drilling is in error, the adjustable range of positioning can be increased.

[0021] Numbering explanation (in order of first appearance): 100 Mounting base, 110 Base bottom plate, 120 Base side plate, 121 L-shaped slot, 111 First slot, 112 Second slot, 113 Hanger mounting hole group, 1131 Rectangular hole, 1132 Rectangular strip hole, 200 Support hanger, 210 Hanger bottom plate, 220 Hanger side plate, 230 U-shaped slot, 240 Base plate bending edge. Detailed Implementation

[0022] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0023] like Figure 1 The image shows one embodiment of a combined snap-fit ​​tunnel load-bearing support bracket according to this utility model, comprising:

[0024] One mounting base 100 is a U-shaped plate, consisting of one base bottom plate 110 and two base side plates 120 on the left and right. Each of the two base side plates 120 has an L-shaped slot 121 at its upper end. The base bottom plate 110 has at least two sets of hanger mounting holes 113.

[0025] At least two support hangers 200 are U-shaped plates, and one end of the support hanger 200 is inserted into the hanger mounting hole group 113. The description of insertion means that one end of the support hanger 200 is made into a certain shape and directly inserted into the hanger mounting hole group 113 for snap-fit ​​fixation, which does not include other forms of auxiliary fixing connection such as screws, bolts, nuts, welding, etc.

[0026] In actual production, the U-shaped plate is made of 2mm thick steel plate. Since the combined snap-fit ​​tunnel load-bearing support provided by this utility model is used in tunnels, it is mostly used to support cables in the tunnel. Since the cables are relatively light, the 2mm thick steel plate fully meets the strength requirements. Moreover, the material of the U-shaped plate is often Q235B, and its processing method is bending or stamping.

[0027] For ease of description, Figure 1 As shown in the figure, the upper part of the image is defined as the top side, and the same applies to other directions.

[0028] like Figure 2 As shown, the above-mentioned hanger mounting hole group 113 includes one rectangular hole 1131 and two rectangular strip holes 1132, and the rectangular strip holes 1132 are located below the rectangular hole 1131 and are symmetrically distributed on the left and right sides relative to the base plate 110.

[0029] In the specific implementation process, the rectangular hole 1131 is designed as a vertical hole of 22mm x 35mm, the rectangular strip hole 1132 is 3mm x 31mm in size, the vertical distance between the centers of the two holes is 30mm, and the horizontal center distance between the two rectangular strip holes 1132 is 34mm.

[0030] like Figure 3 The image shows an embodiment of the support hanger 200, which consists of a hanger base plate 210 and two hanger side plates 220 on the left and right. The hanger base plate 210 has two U-shaped slots 230 on one side, with the openings facing the left and right sides.

[0031] The aforementioned hanger side plate 220 has two U-shaped slots 230 on one side, with the openings facing downwards; a chamfer is provided at the upper corner of the same side end; the aforementioned four U-shaped slots 230 are all provided on the same side end of the support hanger 200.

[0032] Similarly, Figure 3 As shown, the side plate 220 of the hanger is designed in a trapezoidal shape, that is, one side with the U-shaped slot 230 is the long side and the other side is the short side. The advantage of this design is that it can increase the load-bearing capacity of the support hanger 200. This is also the optimal shape designed according to the theory of mechanics of materials. It can increase the bending and shear resistance of the cross section of the side plate 220. For the support hanger 200 that bears load for a long time, if the strength is insufficient, the support hanger 200 will gradually bend over time, increasing the risk of accidents. Moreover, this design can reduce the use of materials, obtain the required strength with less material, and achieve better economic efficiency. At the same time, it can achieve the effect of weight reduction and reduce transportation costs.

[0033] The following describes the specific installation method of the combined snap-fit ​​tunnel load-bearing support provided by this utility model. First, the L-shaped slot 121 opened at the upper end of the base side plate 120 needs to be attached and welded together with the installation plate in the tunnel. Then, the support side plate 220 of the support hanger 200 is facing upwards, and the chamfered edge of the support side plate 220 is parallel to the surface of the base bottom plate 110 of the support hanger 200 and inserted into the hanger mounting hole group 113 at the hanger bottom plate 210. Then, the support hanger 200 is rotated 90 degrees left and right until the outer side of the hanger bottom plate 210 faces upwards. Then, the support hanger 200 is rotated up and down until the outer side of its hanger bottom plate 210 is horizontal. Then, the support hanger 200 is moved downwards until the two U-shaped slots 230 at the support side plate 220 are snapped into the bottom of the rectangular strip hole 1132. At this time, the installation is completed. Other support hangers 200 are installed in the same way as above.

[0034] The other end of the aforementioned hanger base plate 210 is also provided with a base plate bending edge 240. The purpose of this base plate bending edge 240 is to prevent the cable carried on the support hanger 200 from rolling off the bearing surface of the support hanger 200. In practice, it is impossible to guarantee that every support hanger 200 can be installed horizontally on the mounting base 100. Considering the factors of processing accuracy and consistency, the addition of the base plate bending edge 240 can effectively prevent the cable from rolling off the bearing surface of the support hanger 200. After the cable falls to the bottom surface, it may be corroded, increasing the safety hazard.

[0035] The surface treatment of the aforementioned load-bearing supports is hot-dip galvanizing or color galvanizing. Due to the harsh working environment in tunnels, load-bearing supports are prone to moisture, weathering, and other forms of erosion. Therefore, their surfaces need to have strong rust and corrosion resistance. During the production process, the thickness of the galvanized layer on the support surface must be sampled and tested in real time to ensure its service life. Salt spray tests are also required. Only if the surface is not corroded after the required time has been reached in a set concentration of fumes can it be considered qualified.

[0036] The base plate 110 has a first slot 111 on its upper side and a second slot 112 on its lower side. The first slot 111 and the second slot 112 are arranged in the normal direction. Depending on the work scenario, sometimes it is necessary to add bolt and nut installation and fixing methods, so it is necessary to design slots. The advantage of the normal arrangement is that no matter which direction the hole is drilled in, the adjustable range of positioning can be increased.

[0037] The specific embodiments of the utility model have been described in detail above, but they are only examples, and the utility model is not limited to the specific embodiments described above. For those skilled in the art, any equivalent modifications or substitutions to the utility model are also within the scope of the utility model. Therefore, all equivalent transformations, modifications, and improvements made without departing from the spirit and principles of the utility model should be covered within the scope of the utility model.
