Description

Technical Field

[0001] This utility model relates to the field of mobile house technology, specifically a quick-assembly connection device for the steel structure of mobile houses. Background Technology

[0002] Prefabricated houses are a new type of environmentally friendly and economical mobile home. They are constructed with a light steel frame and sandwich panels as enclosure materials. The components are connected by bolts. From a structural perspective, the light steel frame gives the prefabricated house good stability and load-bearing capacity, and can withstand certain wind and snow loads. The sandwich panels are usually made of materials such as polystyrene and rock wool, which not only have good thermal insulation performance, but also play a certain role in sound insulation, improving the comfort of living or using the house.

[0003] Prefabricated houses are widely used as temporary dormitories on construction sites. The steel structure of the prefabricated house is the key support system. It is mainly composed of various types of steel and steel plates, which are combined by welding, bolting and other methods. The steel structure is an important load-bearing component, mainly bearing the load of the roof, and bolting is the main way of connecting steel structures.

[0004] While bolted connections can meet the connection requirements of steel structures, in order to ensure the overall connection strength, the number of bolts at the connection point needs to be increased. This means that a large number of bolts need to be screwed in the connection of the prefabricated house. The screwing process is tedious and time-consuming. Moreover, under the long-term vibration and impact load environment of the construction site, the bolts are prone to loosening, which will eventually affect the overall strength of the prefabricated house. Therefore, a quick-assembly connection device for steel structure of prefabricated houses is proposed to address the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a quick-assembly connection device for steel structure of mobile homes to solve the problems mentioned in the background art.

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

[0007] A quick-assembly connection device for a prefabricated steel structure includes a steel frame beam. A connecting support is provided on one side of the steel frame beam. Connecting grooves adapted to the steel frame beam are symmetrically opened on both sides of the top of the connecting support. An anti-detachment component is provided between the steel frame beam and the connecting groove. A connecting support plate is fixedly connected to one end of the bottom of the steel frame beam. A limiting component and a connecting component are provided between the end of the connecting support plate and the connecting support. The anti-detachment component includes a ratchet strip and an anti-detachment groove. The ratchet strip is fixedly installed in the inner bottom of the connecting groove. The anti-detachment groove is opened at the bottom of the steel frame beam. An anti-detachment pawl is provided at one end of the inner cavity of the anti-detachment groove. The anti-detachment pawl is rotatably connected to the inner wall of the anti-detachment groove through a rotating shaft.

[0008] As a further optimization of this utility model, the anti-detachment groove and the ratchet strip are set in equal numbers, corresponding positions and matching specifications, and the anti-detachment pawl is adapted to the ratchet strip.

[0009] As a further optimization of this utility model, the limiting component includes a limiting groove and a plug-in groove. The limiting groove is symmetrically opened in the end cavity of the connecting support. The plug-in groove communicates with the limiting groove and penetrates the side wall of the connecting support.

[0010] As a further optimization of this utility model, a return spring is fixedly connected to the inner end face of the limiting groove, and a movable plate is fixedly connected to the end of the return spring away from the inner end face of the limiting groove. The movable plate is slidably connected to the inner wall of the limiting groove.

[0011] As a further optimization of this utility model, the following features are provided: a limit block is fixedly connected to the end of the movable plate away from the reset spring, and a plug-in block is symmetrically and fixedly connected to the side of the connecting support plate near the connecting support.

[0012] As a further optimization of this utility model, the plug-in block and the plug-in slot are positioned correspondingly and matched in specifications, and the plug-in block has a limiting slot adapted to the limiting slot on the side near the limiting block.

[0013] As a further optimization of this utility model, the connecting component includes a connecting bolt that passes through the center of the connecting support plate, and the end of the connecting support is provided with a connecting screw hole that corresponds to the position of the connecting bolt and matches its specifications.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] In this invention, the connecting support and its connecting groove provide a foundation for the connection of the steel frame beam. The anti-detachment component provides anti-detachment capability for the connection between the steel frame beam and the connecting groove, ensuring good stability when the steel frame beam slides into the connecting groove. The limiting component provides good limiting capability for the connection between the steel frame beam and the connecting groove, further reducing the possibility of detachment after the steel frame beam slides into the connecting groove. The connecting component provides stable connection strength for the connection between the steel frame beam and the connecting support. With the anti-detachment component, limiting component, and connecting component, the connection between the steel frame beam and the connecting support is quick and easy, and avoids the overall strength of the prefabricated house being affected by bolt loosening later due to the use of only bolt connection.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0026] Please see Figures 1-7 This utility model provides a technical solution:

[0027] A quick-assembly connection device for a prefabricated steel structure includes a steel frame beam 1. A connecting support 2 is provided on one side of the steel frame beam 1. Connecting grooves 3 adapted to the steel frame beam 1 are symmetrically opened on both sides of the top of the connecting support 2. An anti-detachment component 4 is provided between the steel frame beam 1 and the connecting groove 3. A connecting support plate 5 is fixedly connected to one end of the bottom of the steel frame beam 1. A limiting component 6 and a connecting component 7 are provided between the end of the connecting support plate 5 and the connecting support 2. The anti-detachment component 4 includes a ratchet strip 41 and an anti-detachment groove 42. The ratchet strip 41 is fixedly installed in the inner bottom of the connecting groove 3. The anti-detachment groove 42 is opened in the bottom of the steel frame beam 1. An anti-detachment pawl 43 is provided at one end of the inner cavity of the anti-detachment groove 42. The anti-detachment pawl 43 is rotatably connected to the inner wall of the anti-detachment groove 42 through a rotating shaft.

[0028] It should be noted that the anti-detachment groove 42 and the ratchet strip 41 are set in equal numbers, corresponding positions and matching specifications, and the anti-detachment pawl 43 is compatible with the ratchet strip 41.

[0029] Furthermore, in the above configuration, the connection between the steel frame beam 1 and the connecting support 2 is made quick and easy through the anti-detachment component 4, the limiting component 6, and the connecting component 7. This not only makes the entire connection process quick and easy, but also avoids the overall strength of the mobile house from being affected by the subsequent loosening of bolts due to the use of only bolt connections.

[0030] Specifically: In the above configuration, the combined use of the anti-detachment pawl 43 and the ratchet strip 41 can provide anti-detachment capability for the connection between the steel frame beam 1 and the connecting groove 3.

[0031] As a further implementation of this solution, the limiting component 6 includes a limiting groove 61 and a plug-in groove 62. The limiting groove 61 is symmetrically opened in the end cavity of the connecting support 2. The plug-in groove 62 communicates with the limiting groove 61 and penetrates the side wall of the connecting support 2. A return spring 63 is fixedly connected to the inner end face of the limiting groove 61. A movable plate 64 is fixedly connected to the end of the return spring 63 away from the inner end face of the limiting groove 61. The movable plate 64 is slidably connected to the inner wall of the limiting groove 61. A limiting block 65 is fixedly connected to the end of the movable plate 64 away from the return spring 63. A plug-in block 66 is symmetrically and fixedly connected to the side of the connecting support plate 5 near the connecting support 2. The plug-in block 66 and the plug-in groove 62 are positioned correspondingly and matched in specifications. A limiting groove 67 adapted to the limiting block 65 is opened on the side of the plug-in block 66 near the limiting block 65.

[0032] Furthermore, in the above configuration, the limiting component 6 can provide good limiting capability for the connection between the steel frame beam 1 and the connecting groove 3, further reducing the possibility of the steel frame beam 1 detaching after sliding into the connecting groove 3.

[0033] As a further implementation of this solution, the connecting component 7 includes a connecting bolt 71 that passes through the center of the connecting support plate 5, and the end of the connecting support 2 is provided with a connecting screw hole 72 that corresponds to the position of the connecting bolt 71 and matches its specifications.

[0034] Furthermore, in the above configuration, the connecting component 7 can provide stable connection strength for the connection between the steel frame beam 1 and the connecting support 2.

[0035] Workflow: Two steel frame beams 1 are connected via connecting supports 2. During connection, the end of the steel frame beam 1 with the anti-detachment groove 42 is first slid into the corresponding connecting groove 3 on the top of the connecting support 2 until the steel frame beam 1 slides to the innermost end of the connecting groove 3. At the same time, the anti-detachment groove 42 will correspond to the position of the ratchet pawl 41. During the sliding of the steel frame beam 1, the anti-detachment pawl 43 will contact the ratchet pawl 41. Due to the inclined surface of the ratchet pawl 41, the anti-detachment pawl 43 will rotate on the inclined surface of the ratchet pawl 41 via the pivot. Sliding will not hinder the forward movement of the steel frame beam 1 in the connecting groove 3. When the steel frame beam 1 tends to move outward, the anti-loose pawl 43 will contact the vertical surface of the ratchet strip 41. Due to the vertical surface design of the ratchet strip 41, the anti-loose pawl 43 cannot pass over the ratchet and is blocked by the ratchet strip 41. At this time, a large resistance will be generated. Through the interaction between the anti-loose pawl 43 and the ratchet strip 41, the reverse movement of the steel frame beam 1 can be effectively prevented, so that the steel frame beam 1 has good stability when it slides into the connecting groove 3.

[0036] When the steel frame beam 1 slides to the innermost end of the connecting groove 3, the plug block 66 on one side of the connecting support plate 5 will be inserted into the plug groove 62 at the end of the connecting support 2. At the same time, the plug block 66 will press the limiting block 65. After being pressed, the limiting block 65 will drive the movable plate 64 to move into the limiting groove 61, and at the same time press the return spring 63. The return spring 63 will then drive the movable plate 64 and the limiting block 65 to return to their original position through its own rebound force. The returned limiting block 65 will be inserted into the limiting groove 67 opened on the plug block 66 for locking and limiting, thereby further reducing the possibility of the steel frame beam 1 detaching after sliding into the connecting groove 3.

[0037] When the steel frame beam 1 slides to the innermost end of the connecting groove 3, the connecting support plate 5 will fit against the end of the connecting support 2, and at the same time, the hole position of the connecting bolt 71 in the connecting assembly 7 will correspond to the position of the connecting screw hole 72. Finally, you only need to screw the connecting bolt 71 into the connecting screw hole 72.

[0038] It is worth noting that when connecting the steel frame beam 1 to the connecting support 2, simply slide the end of the steel frame beam 1 with the anti-detachment groove 42 into the connecting groove 3 and continue sliding it to the innermost end of the connecting groove 3. Finally, only a small number of connecting bolts 71 need to be screwed in. During this process, the anti-detachment component 4 and the limiting component 6 do not require any operation and will automatically function during the sliding. Therefore, not only is the entire connection process quick and easy, but it can also avoid the overall strength of the mobile house being affected by the subsequent loosening of bolts due to the use of only bolt connections.

[0039] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
