Description

Technical Field

[0001] This utility model relates to the field of clamping technology, specifically to a flat steel clamp assembly structure. Background Technology

[0002] Flat steel is an extremely important basic steel material, named for its rectangular cross-section and flat shape, where the width is much greater than the thickness. This shape gives it many unique advantages, making it widely and diversely used in numerous industrial and engineering fields. In tunnel construction, flat steel can be used as structural connectors and reinforcements, serving a connecting and strengthening function; it can also be used as a core component of tunnel support systems, for the assembly of prefabricated support structures and as flexible support for tunnel pre-support, ensuring tunnel construction safety; it can also be used for pipe fixing clamps, cable tray supports, etc., providing protection for electromechanical components against mechanical damage and electrochemical corrosion; in addition, flat steel can also be used as grounding components for cable routing structures in tunnels, ensuring the safe use of cables and various electromechanical equipment inside the tunnel.

[0003] However, in the use of flat steel, traditional conventional clamps are usually more suitable for clamping and fixing round steel. For flat steel, construction workers usually tie or weld it manually, which is labor-intensive and risky. In the existing technology, there is a type of flat steel clamp designed with reference to round steel clamps for clamping and fixing flat steel. However, when using this type of flat steel clamp, both ends of the clamping structure need to be fixed separately and additional connecting structures need to be set up to connect with the fixing structure inside the tunnel to complete the fixing of the flat steel. The convenience in actual use is still low.

[0004] This shows that existing technologies still have certain shortcomings. Utility Model Content

[0005] The purpose of this utility model is to provide a flat steel clamp assembly structure to solve the problems of poor ease of use, poor flexibility and versatility in the actual use of existing flat steel clamping structures / devices.

[0006] To achieve the above objectives, this utility model provides a flat steel clamp assembly structure, which includes an assembly groove and clamps. One or more clamps are provided, and the multiple clamps are arranged along the extension direction of the assembly groove. Each clamp includes two clamping pieces arranged opposite to each other along the extension direction of the assembly groove. Each clamping piece sequentially includes a locking part, a clamping part, and a limiting part that cooperates with the assembly groove. The assembly groove is provided with multiple limiting protrusions that can limit and cooperate with the limiting part. A clamping space for fixing the flat steel is formed between the clamping part of the two clamping pieces and the assembly groove.

[0007] The clamping part is generally L-shaped and includes a first clamping section and a second clamping section connected to each other. The locking part is connected to the end of the first clamping section away from the second clamping section, and the limiting part is connected to the end of the second clamping section away from the first clamping section. The locking part and the limiting part extend in a direction away from the first clamping section. The end of the first clamping section connected to the locking part is inclined towards the inside of the clamping space compared to the end of the first clamping section connected to the second clamping section.

[0008] In the above scheme, the upper limit of the clamping plate and the upper limit protrusion of the assembly groove cooperate to achieve the limiting and fixing of the clamp and the flat steel on the assembly groove while the clamp is clamping the flat steel. There is no need for a separate connecting structure or limiting structure to limit the clamp. In addition, the clamp in the above scheme can be flexibly adjusted in position along the extension direction of the assembly groove, which is convenient to adapt to the clamping and fixing of flat steel in different installation positions and for different installation purposes. It has a wide range of applications and stronger versatility. At the same time, the assembly groove in the above scheme can be connected to the building structure through pre-embedded parts such as pre-embedded bolts, which makes the setting of the entire flat steel clamping structure more convenient, flexible and adaptable to different installation needs. It is not only suitable for tunnel construction but also for many other types of engineering construction or equipment manufacturing. In addition, with the above structure, when the locking parts of the two clamping plates in the clamp are locked, the end of the first clamping section will tend to tilt further toward the inside of the clamping space under the action of the locking parts, thereby further improving the clamping force of the first-stage clamping section on the clamped flat steel and improving the fixing effect of the clamp on the flat steel.

[0009] In a preferred embodiment of this application, the inner wall of the assembly groove is provided with the limiting protrusions, and the plurality of limiting protrusions are evenly arranged along the extension direction of the assembly groove.

[0010] In the above scheme, the assembly slot is preferably a T-shaped slot. The T-shaped structure facilitates the installation and position adjustment of the fixture, improves the flexibility of the flat steel clamping structure, and makes the limiting engagement between the fixture clamping plates and the limiting protrusions more convenient. At the same time, the T-shaped structure of the assembly slot also facilitates the maintenance and cleaning of the internal space of the assembly slot during subsequent use, and allows for the expansion of the flat steel clamping structure according to actual needs.

[0011] In a preferred embodiment of this application, a mating section is provided at the end of the limiting portion away from the second clamping section. The mating section is disposed in the assembly groove and can be limited and mated with the limiting protrusion.

[0012] In the above scheme, by setting a mating section, it is easier to mate with the limiting protrusion inside the assembly slot, thereby improving mating efficiency and limiting effect.

[0013] In a preferred embodiment of this application, the limiting portion further includes an extension section that is connected to the second clamping section and the mating section respectively, wherein the mating section and the extension section are integrally formed or the mating section and the extension section are detachably connected.

[0014] In the above scheme, by setting an extension section, the connection distance between the mating section and the clamping part can be appropriately adjusted, which makes it easier for construction personnel to manually or use adjustment equipment to hold the clamping part at other positions and apply force to drive the mating section to move inside the assembly slot, thereby improving assembly efficiency and adjustment efficiency, and facilitating later maintenance and replacement.

[0015] In a preferred embodiment of this application, the length of the extension is not less than the wall thickness at the opening of the assembly groove and the width of the extension is not greater than the opening width of the assembly groove.

[0016] In the above solution, by adopting the above structure, it is possible to avoid the excessively tight fit between the extension section, the mating section and the assembly slot, which would cause the clamp to move during the installation or adjustment process and interfere with the assembly slot structure, thereby improving assembly efficiency and the convenience of later maintenance and adjustment.

[0017] In a preferred embodiment of this application, the clamp further includes a fastener, and the locking portions of the two clamping pieces are provided with corresponding connecting holes. The fastener passes through the connecting holes on the two clamping pieces to lock and fix the locking portions of the two clamping pieces.

[0018] In the above scheme, the locking parts have a simple mating structure, reliable assembly, and simple assembly operation, resulting in low usage and maintenance costs.

[0019] In a preferred embodiment of this application, the first clamping segment and the second clamping segment have an 85° angle, and the locking part has an 80° angle with the first clamping segment.

[0020] In the above scheme, the above structural setting can not only improve the clamping ability of the clamping part and the flat steel, but also avoid the difficulty of clamp production caused by excessive tilt angle or the reduction of the structural strength of the clamp itself, thereby reducing production costs.

[0021] In a preferred embodiment of this application, the surface of the clip is provided with a wear-resistant reinforcing layer.

[0022] In the above solution, the wear resistance, corrosion resistance and rust prevention of the clamps can be improved by setting a wear-resistant reinforcing layer, thereby extending the service life of the clamps and reducing the cost of use and maintenance.

[0023] In a preferred embodiment of this application, the assembly slot adopts an integral structure; or, the assembly slot adopts a split structure, including multiple slot segments.

[0024] In the above scheme, the integrated structure of the assembly slot can improve the structural strength of a single assembly slot and is suitable for heavy-duty connections, while the split structure makes the installation and arrangement of the assembly slot more flexible and adaptable to different installation needs, thus improving the versatility of the structure.

[0025] In a preferred embodiment of this application, the inner wall of the clamping part is provided with a resistance-increasing pad.

[0026] In the above solution, by setting a friction-increasing shim, the frictional resistance between the clamp and the flat steel can be reduced after the clamp clamps the flat steel, thereby further improving the clamping capacity of the clamp for the flat steel. In addition, by setting a friction-increasing shim, it can also adapt to the clamping requirements of thinner flat steel, thus improving the versatility of the clamp in this application.

[0035] To more clearly illustrate the overall concept of this utility model, a detailed description will be provided below with reference to the accompanying drawings.

[0036] It should be noted that many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0037] like Figures 1-3 As shown, this application provides a flat steel clamp assembly structure, which includes an assembly groove 1 connected to the building body structure and a clamp 2 that cooperates with the assembly groove 1. One or more clamps 2 are provided, and the multiple clamps 2 are arranged along the extension direction of the assembly groove 1. The clamp 2 includes two clamping pieces 21 arranged opposite to each other along the extension direction of the assembly groove 1. Each clamping piece 21 includes a locking part 211, a clamping part 212 and a limiting part 213 that cooperates with the assembly groove 1 in sequence. The assembly groove 1 is provided with multiple limiting protrusions 11 that can cooperate with the limiting part 213 for limiting. The clamping part 212 of the two clamping pieces 21 and the assembly groove 1 are surrounded by a clamping space 22 that is adapted to the shape of the flat steel 3 for fixing the flat steel 3. In the above scheme, by cooperating with the limiting part 213 on the clamping piece 21 and the limiting protrusion 11 on the assembly groove 1, the clamping piece 2 and the flat steel 3 can be limited and fixed on the assembly groove 1 at the same time as the clamping piece 2 clamps the flat steel. There is no need to set up a separate connecting structure or limiting structure to limit the clamping piece 2. In addition, the clamping piece 2 can be flexibly adjusted in position along the extension direction of the assembly groove 1, which is convenient to adapt to the clamping and fixing of the flat steel 3 in different installation positions and for different installation purposes. It has a wide range of applications and stronger versatility.

[0038] Preferably, the assembly groove 1 in this application can be connected to the building structure through pre-embedded parts such as bolts, making the entire flat steel clamping structure more convenient, flexible, and adaptable to different installation needs. It is applicable not only to tunnel construction but also to the connection of other types of construction projects or equipment. It should be noted that this application does not specifically limit the connection method or structure between the assembly groove 1 and the building structure or equipment structure. It can use the connection method described above, the method of directly pre-embedding the assembly groove 1, or other different methods such as welding.

[0039] In addition, as a preferred embodiment of this application, the assembly slot 1 adopts an integrated structure. The integrated structure can improve the structural strength of a single assembly slot 1 and is suitable for heavy-duty connections. Alternatively, the assembly slot 1 adopts a split structure, including multiple slot segments. The complete assembly slot 1 structure is formed by connecting the multiple slot segments. Although this setting increases the difficulty of installing and forming the assembly slot 1 to a certain extent and the load-bearing capacity of a single slot segment is relatively low, the split structure makes the installation arrangement of the assembly slot 1 more flexible and adaptable to different installation needs, and can effectively improve the versatility of the flat steel clamp assembly structure.

[0040] Furthermore, refer to Figure 1 and Figure 2 As shown, the clamp 2 also includes a fastener 23. The locking portions 211 of both clamping pieces 21 are provided with corresponding connecting holes 2111. The fastener 23 passes through the connecting holes 2111 on the two clamping pieces 21 to lock and fix the locking portions 2111 of the two clamping pieces 21. Preferably, the fastener 23 is a bolt and a nut. In use, the bolt passes through the connecting holes 2111 on the locking portions 211 of the two clamping pieces 21 and engages with the nut to lock the locking portions 2111 of the two clamping pieces 21 together firmly. In the above solution, the mating structure between the locking portions 211 is simple, the assembly is reliable and the assembly operation is simple, and the use and maintenance costs are low.

[0041] Continue to refer to Figure 3 As shown, the clamping portion 212 is generally L-shaped, including a first clamping segment 2121 and a second clamping segment 2122 connected to each other. A locking portion 211 is connected to the end of the first clamping segment 2121 away from the second clamping segment 2122, and a limiting portion 213 is connected to the end of the second clamping segment 2122 away from the first clamping segment 2121. The locking portion 211 and the limiting portion 213 extend in a direction away from the first clamping segment 2121. The end of the first clamping segment 2121 connected to the locking portion 211 is inclined towards the inside of the clamping space 22 compared to the end of the first clamping segment 2121 connected to the second clamping segment 2122. Preferably, there is an 85° angle between the first clamping segment 2121 and the second clamping segment 2122, and an 80° angle between the locking portion 211 and the first clamping segment 2121. The above-mentioned structural arrangement can improve the clamping capacity of the clamping part 212 and the flat steel 3, and avoid the production difficulties of the clamping piece 21 or the reduction of the structural strength of the clamping piece 21 itself due to excessive tilt angle, thereby reducing production costs.

[0042] By adopting the above structure, the L-shaped main structure allows the clamping part 212 to obtain a shape that adapts to the shape of the flat steel 3, thereby increasing the contact area between the clamping part 212 and the flat steel 3. At the same time, when the locking parts 211 of the two clamping pieces 21 in the clamp 2 are locked, the end of the first clamping section 2121 will tend to tilt further toward the inside of the clamping space 22 under the action of the locking parts 211, thereby further improving the clamping force of the first clamping section on the clamped flat steel 3 and improving the fixing effect of the clamp 2 on the flat steel 3.

[0043] It should be noted that the structural arrangement of the first clamping section 2121, the second clamping section 2122 and the locking part 211 in this application is not limited to the above example. The above example is only a preferred example of this application, and other different structural arrangements can also be adopted. This application does not make specific limitations on this.

[0044] In one example, refer to Figure 1 As shown, the assembly groove 1 has a T-shaped cross-section, and multiple limiting protrusions 11 are provided on the inner wall of the assembly groove 1. The multiple limiting protrusions 11 are evenly arranged along the extension direction of the assembly groove 1. Preferably, the above-mentioned limiting protrusions 11 are limiting teeth. The T-shaped structure of the assembly groove 1 facilitates the installation and position adjustment of the clamp 2, improves the flexibility of the flat steel clamping structure, and makes the limiting engagement between the clamping piece 21 of the clamp 2 and the limiting protrusions 11 more convenient. At the same time, the T-shaped structure of the assembly groove 1 also facilitates the maintenance and cleaning of the internal space of the assembly groove 1 during subsequent use and facilitates the expansion of the flat steel clamping structure according to actual needs during subsequent use. Using limiting teeth as limiting protrusions 11 facilitates their limiting engagement with the limiting part 213, and also reduces the processing difficulty and the processing, use and maintenance costs of the assembly groove 1.

[0045] Furthermore, referring to Figure 2 and Figure 3 As shown, a mating section 2132 is provided at the end of the limiting part 213 away from the second clamping section 2122. The mating section 2132 is disposed in the assembly groove 1 and can engage with the limiting protrusion 11 for limiting. (Continue referring to...) Figure 2 and Figure 3As shown, the limiting part 213 also includes an extension part 2131 connected to the second clamping part 2122 and the mating part 2132 respectively. In the above solution, by setting the mating part 2132, it is easier to cooperate with the limiting protrusion 11 inside the assembly groove 1, thereby improving the cooperation efficiency and limiting effect. By setting the extension part 2131, the connection distance between the mating part 2132 and the clamping part 212 of the clamping piece 21 can be appropriately adjusted, thereby making it easier for construction personnel to manually or use adjustment equipment to hold the clamping piece 21 at other positions and apply force to drive the mating part 2132 to move inside the assembly groove 1, thereby improving the assembly efficiency and adjustment efficiency, and facilitating later maintenance and replacement.

[0046] In a preferred embodiment of this application, the mating section 2132 and the extension section 2131 are integrally formed or detachably connected. For example, the mating section 2132 and the extension section 2131 can be integrally cut or welded, or both the mating section 2132 and the extension section 2131 may have connecting holes 2111, which are then connected and locked using fasteners 23 such as rivets or bolts. It should be noted that the connection method and structure between the mating section 2132 and the extension section 2131 in this application are not limited to the above examples. The above examples are only some preferred examples of this application, and other different configurations can also be adopted. This application does not specifically limit these configurations. The integral molding of the mating section 2132 and the extension section 2131 can improve the connection strength between the mating section 2132 and the extension section 2131. The separate connection of the mating section 2132 and the extension section 2131 makes it easier to flexibly adjust and select a more suitable mating section 2132 and / or limiting section according to actual installation requirements, thereby facilitating cooperation with assembly slots 1 of different specifications or other connection structures, and greatly improving the versatility of the fixture 2 in this application.

[0047] In a preferred example, refer to Figure 1 and Figure 3 As shown, the length of the extension section 2131 is not less than the wall thickness at the opening of the assembly slot 1, and the width of the extension section 2131 is not greater than the opening width of the assembly slot 1. This structure avoids the extension section 2131, the mating section 2132, and the assembly slot 1 from being too tightly fitted, which could cause the clamping piece 21 to move during installation or adjustment and interfere with the structure of the assembly slot 1, thus improving assembly efficiency and the convenience of subsequent maintenance and adjustment.

[0048] Furthermore, in a preferred embodiment of this application, the surface of the clamping piece 21 is provided with a wear-resistant reinforcing layer, and a friction-increasing shim is also provided between the inner wall of the clamping part 212 and the flat steel 3. Preferably, the surface of the clamping piece 21 is provided with a galvanized layer, i.e., the aforementioned wear-resistant reinforcing layer, using a hot-dip galvanizing process. A friction-increasing shim can also be provided between the flat steel 3 and the assembly groove 1. In the prior art, the galvanizing process is mature and low in cost. In general use environments such as non-strong corrosion and high strength environments, the galvanized layer can provide sufficient wear resistance, corrosion resistance, and rust prevention for the clamping piece 21, thereby extending the service life of the clamping piece 21 and reducing the cost of use and maintenance. By providing a friction-increasing shim, the frictional resistance between the clamping piece 2 and the flat steel 3 can be reduced after the clamping piece 2 clamps the flat steel 3, thereby further improving the clamping capacity of the clamping piece 2 for the flat steel 3. Moreover, by providing a friction-increasing shim, the clamping requirements of the thinner flat steel 3 can also be met, improving the versatility of the clamping piece 2 in this application.

[0049] The technical solutions protected by this utility model are not limited to the above embodiments. It should be noted that any combination of the technical solutions of any embodiment with one or more other embodiments is within the protection scope of this utility model. Although this utility model has been described in detail above with general descriptions and specific embodiments, some modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, all such modifications or improvements made without departing from the spirit of this utility model are within the scope of protection claimed by this utility model.
