Description

Technical Field

[0001] This utility model relates to the field of support and hanger technology, and in particular to an adjustable 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 tunnel construction, load-bearing supports are mostly used to support electrical systems. Since the tunnel wall is cylindrical and has a certain curvature, and in order to ensure the load-bearing effect of the supports, the load-bearing surface of the supports must always be horizontal. Therefore, this invention provides an adjustable tunnel load-bearing support.

[0004] Traditional load-bearing supports are connected to the middle connecting plate and the load-bearing support plate by welding; this method has high production costs and relatively low production efficiency. For the entire tunnel electrical system, a large number of load-bearing supports are required, so economy and production efficiency are also factors to be considered in the production of supports. In order to solve this problem, the adjustable tunnel load-bearing support provided by this utility model uses components that are all stamped and formed, and the connection method is a screw-detachable connection, which is economical and efficient. Utility Model Content

[0005] The main objective of this invention is to provide an adjustable tunnel support bracket to solve the problems of uniformly arranging support brackets along the tunnel wall and the high production cost and low production efficiency of the existing support brackets.

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

[0007] An adjustable tunnel support bracket, the support bracket comprising:

[0008] The support base is an L-shaped plate, and a first slot and a second slot are respectively opened at both ends of one side plate of the support base;

[0009] An arc-shaped slot and a first circular hole are provided on the other side plate of the support base at a position relative to the center, and the first circular hole is located at the center of the circle indicated by the arc-shaped slot;

[0010] The middle connecting plate is an L-shaped plate with five round holes on one side, from top to bottom: second round hole, third round hole, fourth round hole, fifth round hole, and sixth round hole; wherein the second round hole corresponds to the first round hole, the third round hole corresponds to the arc-shaped slot hole, and the support base and the middle connecting plate are locked and fixed by fixing screws and fixing nuts.

[0011] The load-bearing support plate is an L-shaped plate with two round holes on one side, both located at one end; from top to bottom, they are the seventh and eighth round holes respectively; the seventh and eighth round holes correspond to the fourth and fifth round holes respectively, and the load-bearing support plate and the middle connecting plate are locked and fixed by fixing screws and fixing nuts.

[0012] As a further improvement of this utility model, the first slot and the second slot are arranged in the normal direction.

[0013] As a further improvement of this utility model, the L-shaped plate is made of Q235B material.

[0014] As a further improvement of this utility model, the surface treatment of the support bracket is hot-dip galvanizing or color galvanizing.

[0015] As a further improvement of this utility model, the inner side of the support base is fitted and connected to the outer side of the middle connecting plate; the inner side of the middle connecting plate is fitted to the outer side of the load-bearing support plate.

[0016] As a further improvement of this utility model, the fourth circular hole is opened at the center of one side end of the middle connecting plate.

[0017] Furthermore, the adjustable angle range of the middle connecting plate around the support base is 0-100°.

[0018] The beneficial effects of this utility model are as follows: by opening an arc-shaped slot on one side plate of the support base, the support base and the intermediate connecting plate can rotate at a certain angle, achieving an adjustable effect; the hot-dip galvanizing or color zinc plating surface treatment process greatly increases the service life of each component; at the same time, the connection between the load-bearing support plate and the intermediate connecting plate, and between the intermediate connecting plate and the support base, are all detachable connections, increasing the interchangeability between components, and the absence of welding connections results in lower production costs, improved production efficiency, and greater economic efficiency.

Detailed Implementation

[0025] 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.

[0026] like Figure 1 The image shows an embodiment of an adjustable tunnel load-bearing support according to the present invention, comprising:

[0027] The support base 100 is an L-shaped plate, and a first slot 121 and a second slot 122 are respectively opened at both ends of one side plate of the support base 100;

[0028] For ease of explanation, the corner side of the 100L-shaped plate of the support base is defined as the outer side; and the vertical direction of the outer end of the slotted side plate is defined as the upper end.

[0029] An arc-shaped slot 130 and a first circular hole 110 are provided on the other side plate of the support base 100 at a position relative to the center, and the first circular hole 110 is located at the center of the circle indicated by the arc-shaped slot 130.

[0030] The middle connecting plate 200 is an L-shaped plate with five round holes on one side, from top to bottom: second round hole 210, third round hole 220, fourth round hole 230, fifth round hole 240, and sixth round hole 250. The second round hole 210 corresponds to the first round hole 110, and the third round hole 220 corresponds to the arc-shaped slot hole 130. The support base 100 and the middle connecting plate 200 are locked and fixed by fixing screws 400 and fixing nuts 500.

[0031] The load-bearing support plate 300 is an L-shaped plate with two round holes on one side, both located at one end; from top to bottom, they are the seventh round hole 310 and the eighth round hole 320; the seventh round hole 310 and the eighth round hole 320 correspond to the fourth round hole 230 and the fifth round hole 240, respectively, and the load-bearing support plate 300 and the middle connecting plate 200 are locked and fixed by fixing screws 400 and fixing nuts 500.

[0032] The L-shaped plate described in this utility model is actually produced by stamping or bending. Of course, depending on the specific working conditions, structural steel can be used; structural steel has better strength, but the corresponding cost will be higher.

[0033] When installing the load-bearing support provided in this utility model, the side of the support base 100 with the slotted hole should be attached to the inner surface of the tunnel wall and the support base 100 should be fixed to the inner surface of the tunnel wall with fixing screws 400. The inner surface of the tunnel wall has a certain curvature and is therefore relatively uneven, which inevitably leads to some errors in the process of drilling installation holes on the inner surface of the tunnel wall.

[0034] Therefore, the first slot 121 and the second slot 122 should be arranged in the normal direction; this way, regardless of which direction the drilling causes an error, the adjustable range of positioning can be increased. In the specific implementation process, the thickness of the L-shaped plate is often selected as a thin plate with a thickness of 5mm, the size of the round hole is generally selected as a diameter of 11mm, the selected fixing screw 400 is of specification M10, and it needs to be plated with white zinc or color zinc, or blackened to achieve a certain rust prevention ability.

[0035] The L-shaped plate mentioned above is usually made of Q235B. The reason for choosing Q235B is to consider the economy. Moreover, since the adjustable tunnel load-bearing support provided by this invention is mostly used to support electrical wiring harnesses passing through the tunnel in tunnel conditions, and since the number of load-bearing supports in the tunnel is large and the density is high, and the weight of the wiring harness is relatively low, the weight borne by each load-bearing support is low. Therefore, the L-shaped plate made of Q235B material fully meets the strength requirements. Of course, if it is necessary to support devices with large loads such as pipes, the L-shaped plate made of Q355B material can be used to increase the safety of operation.

[0036] The surface treatment of the aforementioned supports and hangers is hot-dip galvanizing or color galvanizing. Due to the harsh working environment in tunnels, load-bearing supports and hangers 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 surface of the supports and hangers must be sampled and tested in real time to ensure their 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.

[0037] The specific installation method of the adjustable tunnel load-bearing support provided by this utility model is as follows: the inner side of the support base 100 is attached to the outer side of the middle connecting plate 200; the inner side of the middle connecting plate 200 is attached to the outer side of the load-bearing support plate 300.

[0038] The aforementioned fourth circular hole 230 is located at the center of one side plate end of the aforementioned middle connecting plate 200. The main function of the fourth circular hole 230 is to facilitate the fixing of the load-bearing object at the upper end of the support, such as wire harness or pipe. The fixing method can be to use a mounting base formed by bending a thin steel section, or to use a clamp. In special cases, a wire tie can also be used for fixing.

[0039] The adjustable tunnel support bracket provided by this utility model allows the adjustment angle of the middle section connecting plate 200 around the support base 100 to be within the range of 0-100°; of course, this adjustment range can be increased according to the specific installation environment.

[0040] 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.
