Description

Technical Field

[0001] This utility model relates to the field of building beam installation technology, and more specifically, to a building beam hanger. Background Technology

[0002] In building construction, beam hangers are crucial components connecting supporting members (such as columns and beams) to the building's beams. Their stability and installation efficiency directly affect construction safety and progress. Traditional hangers typically employ a single-piece structure, requiring the hanger to be fixed to the supporting member first, followed by placing the beam within the hanger and securing it with welding or bolts. However, this design has significant drawbacks: firstly, the installation sequence is fixed, requiring precise prediction of the beam's position, making adjustments difficult; secondly, dimensional adaptability is poor, requiring custom hangers for beams of different thicknesses, leading to material waste; thirdly, stability depends on manual operation, such as "toenail connections," which require on-site angle adjustments, easily resulting in insufficient connection strength due to construction errors.

[0003] In recent years, some improved solutions have enhanced adaptability through modular design, such as using adjustable support frames or prefabricated assembly structures. However, such technologies still have limitations: the locking mechanism of modular hangers is complex and difficult to disassemble; the pre-set fasteners lack sufficient guiding accuracy, affecting connection reliability.

[0004] Therefore, there is an urgent need for a beam hanger that combines rapid installation and self-adaptive clamping. Utility Model Content

[0005] The main purpose of this utility model is to propose a beam hanger for building construction, which aims to solve the problems of rigid installation sequence and poor size adaptability in traditional technology.

[0010] And / or, the second component further includes a second flange portion perpendicular to the second clamping portion, the second flange portion having a second opening for fixing fasteners.

[0011] In any of the above technical solutions, further, the inner surfaces of the first clamping part and the second clamping part are provided with a plurality of protrusions, which are used to increase the friction between the clamping part and the building beam.

[0015] The second locking tooth includes:

[0016] The main body is provided with slots for engaging the engaging member, and the number of slots is equal to the number of the first locking teeth.

[0017] In any of the above technical solutions, the first component further includes:

[0018] The first rib plate is fixed in the channel and extends in the left-right direction. It has a gap from the inner wall of the channel and has a guide groove extending in the left-right direction.

[0020] The extension has one side connected to the side of the main body and the other side extending through the guide groove to the gap.

[0021] The second rib is fixedly connected to the extension, and its cross-sectional shape is adapted to the cross-sectional shape of the gap.

[0022] In any of the above technical solutions, further comprising:

[0023] The key component has a keyhole on the second clamping part and the second locking tooth, and a connecting hole is provided at each of the slots corresponding to the keyhole. The key component is used to lift the snap-fit ​​component when rotated.

[0024] In any of the above technical solutions, the first locking tooth further includes:

[0025] At least two elastic elements are respectively engaged in the grooves of the two support elements and are used to act downward on the engaging elements.

[0026] In any of the above technical solutions, the first clamping part and / or the second clamping part are provided with an inclined extending guide hole, and the angle between the central axis of the guide hole and the side of the first clamping part is 15°-60°.

[0051] This utility model proposes a beam hanger for construction. Through the clamping parts and locking tooth structure of the first and second components, steel or concrete beams can be quickly fixed, making it suitable for scenarios such as steel structure workshops and the installation of precast bridge components. Furthermore, the fastener openings of the flange support bolt or welded connections, meeting the reliability requirements for low-section beam joint hangers mentioned in "Construction Safety".

[0052] The following embodiments will provide a detailed description of a building beam hanger according to the present application.

[0053] In this embodiment, as Figures 1 to 4 As shown, the building beam hanger includes: a first component 1, including a first clamping part 101 and a first web part 102 extending in the left and right direction, the first web part 102 being provided with a channel 106 and at least one first locking tooth 103;

[0054] The second component 2 includes a second clamping part 201 and a second web part 202 extending in the left and right direction. The second web part 202 is provided with a second locking tooth 203 that cooperates with the first locking tooth 103.

[0055] The first component 1 and the second component 2 are lockably connected by the first locking tooth 103 and the second locking tooth 203 to clamp the building beam between the first clamping part 101 and the second clamping part 201.

[0056] In this technical solution, the first component 1 and the second component 2 are arranged opposite each other on the left and right sides. The first clamping part 101 and the second clamping part 201 are two vertical plate-like structures facing each other on the left and right sides. The bottom right side of the first clamping part 101 is provided with a first web part 102 extending to the right, and the bottom left side of the second clamping part 201 is provided with a second web part 202 extending to the left. The first web part 102 is cuboid in shape, and a rectangular opening extends from its right side to the left to form the aforementioned channel 106. The channel 106 is provided with four first locking teeth 103. The structure of the second locking teeth 203 on the second web part 202 can cooperate with the first locking teeth 103 to lock the distance between the first component 1 and the second component 2 in the left and right directions. In use, the crossbeam is erected on the first web part 102 and the second web part 202, the distance between the first component 1 and the second component 2 is adjusted to tighten the crossbeam, and finally the first component 1 and the second component 2 with the crossbeam erected are fixed to a position such as a roof or bridge.

[0057] In some technical solutions, the first locking tooth 103 and the second locking tooth 203 are mutually cooperating friction ratchet mechanisms, and self-locking is achieved by the engagement of spring-loaded pawls with ratchet wheels (not shown in the figure). Specifically, multiple spring-loaded pawls are evenly arranged in the left-right direction in the channel 106 of the first component 1, and an equal number of ratchet wheels are arranged on the second web portion 202.

[0058] In this embodiment, the first component 1 further includes a first flange portion 104 perpendicular to the first clamping portion 101, and the first flange portion 104 is provided with a first opening for fixing fasteners;

[0059] And / or, the second component 2 further includes a second flange portion 204 perpendicular to the second clamping portion 201, the second flange portion 204 having a second opening for fixing fasteners.

[0060] In this technical solution, the first flange 104 is a plate-shaped structure extending to the left from the front left side of the first clamping part 101, and the second flange 204 is a plate-shaped structure extending to the right from the front right side of the second clamping part 201. The first flange 104 and the second flange 204 are respectively provided with a plurality of first openings and second openings. The first openings and the second openings are through-hole structures, which facilitate the fixing of bolts, rivets and other fixing structures to the object to be installed through the openings.

[0061] In this embodiment, the inner surfaces of the first clamping part 101 and the second clamping part 201 are provided with a plurality of protrusions 3, which are used to increase the friction between the protrusions and the building beam.

[0062] In this technical solution, the inner surface of the first clamping part 101 is the side of the first clamping part 101 that is close to the second clamping part 201, which is the right side of the first clamping part 101. Similarly, the inner surface of the second clamping part 201 refers to its left side. Multiple rows and columns of protrusions 3 are uniformly or unevenly provided on the inner surfaces of both to increase the friction between the component and the crossbeam and improve the fixing effect.

[0063] In this embodiment, the first locking tooth 103 includes:

[0064] Two support members 10301 are symmetrically arranged in the channel 106;

[0065] The snap-fit ​​component 10302 and the support component 10301 are provided with sliding grooves, and the two ends of the snap-fit ​​component 10302 are slidably snapped into the sliding grooves of the two support components 10301.

[0066] The second locking tooth 203 includes:

[0067] The main body 20301 is provided with a slot 20304 for engaging the engaging member 10302, and the number of slots 20304 is equal to the number of first locking teeth 103.

[0068] In this technical solution, four first locking teeth 103 are evenly arranged from left to right. Each first locking tooth 103 includes two support members 10301 and a snap-fit ​​member 10302 that slides on the two support members 10301. Specifically, two first rib portions 105 are symmetrically arranged front and back in the channel 106 of the first component 1. The first rib portions 105 are provided with pin holes. The two corresponding support members 10301 are fixed to the first rib portions 105 by pins, and the top surface of the support member 10301 abuts against the inner top surface of the channel 106 to prevent the support member 10301 from rotating. The side of the support member 10301 near the middle in the front-back direction is provided with a vertical rectangular groove. The snap-fit ​​member 10302 is long and strip-shaped, and its front and rear ends can slide and snap into the grooves of the two support members 10301.

[0069] The main body 20301 of the second locking tooth 203 is rectangular, with a cross-sectional height less than that of the channel 106 and a front-to-back width less than or equal to the distance between two corresponding support members 10301. The main body 20301 has four corresponding slots 20304 extending in the front-to-back direction at left-to-right distances corresponding to the distance between the four locking members 10302. The upper corner of the left side of the main body 20301 is chamfered so that each locking member 10302 can be lifted up one by one as the second member 2 slides to the left in the channel 106.

[0070] Through the interlocking of multiple snap-fit ​​pieces 10302 and multiple snap-fit ​​slots 20304, the first component 1 and the second component 2 can be snapped together to different degrees, which can be adapted to the connection and fixation of crossbeams in different left and right directions.

[0071] It is worth mentioning that during the inward engagement of the first component 1 and the second component 2, once the rightmost support 10301 is engaged in the leftmost slot 20304, the second component 2 cannot be pushed further to the left. Therefore, a chamfer can be provided on the right side of the support 10301 and / or the right side of the slot 20304, allowing the support 10301 to slide out of the slot 20304 through the inclined force of the chamfer as the first component 1 and the second component 2 approach each other. Simultaneously, since the building beam hanger of this application is also equipped with a key 4, restricting the descent of the support 10301 by using the key 4 also achieves the goal of ensuring the proximity of the two components remains unaffected.

[0072] In other technical solutions, the front and rear sides of the first web portion 102 are provided with mounting holes corresponding to each pin hole, which facilitates the installation of the support member 10301 and the snap-fit ​​member 10302 in the channel 106.

[0073] In this embodiment, the first component 1 further includes:

[0074] The first rib portion 105 extends in the left and right direction and is fixed in the channel 106. It has a gap from the inner wall of the channel 106 and has a guide groove extending in the left and right direction.

[0075] The second locking tooth 203 also includes:

[0076] The extension 20302 is connected to the side of the main body 20301 on one side, and extends through the guide groove to the gap on the other side;

[0077] The second rib portion 20303 is fixedly connected to the extension portion 20302, and its cross-sectional shape is adapted to the cross-sectional shape at the gap.

[0078] In this technical solution, the first rib portion 105 is symmetrically arranged in two parts, and similarly, the extension portion 20302 and the second rib portion 20303 are also symmetrically arranged in two parts, thereby improving the symmetry and structural strength of the structure.

[0079] The first rib portion 105 is a plate-like structure vertically arranged in the channel 106, or it is fixed by welding or by bolts at the bottom of the first web portion 102. The first rib portion 105 has a guide groove extending in the left and right direction in the middle, and the height of the guide groove in the vertical direction is equal to the thickness of the extension portion 20302 in the vertical direction. Taking the front extension 20302 and the second rib 20303 as examples, the rear side of the extension 20302 is fixed to the main body 20301, and the front side of the extension 20302 passes through the guide groove and is flush with the front side of the front first rib 105. The front side of the extension 20302 is fixedly connected to the second rib 20303. The height in the vertical direction and the thickness in the front-back direction of the second rib 20303 are equal to the height and width of the gap between the front first rib 105 and the inner front wall of the channel 106. This can improve the stability of the second web 202 in the channel 106, reduce the stress intensity between the main body 20301 and the snap-fit ​​member 10302 when the second web 202 and the first web 102 are subjected to force, and facilitate the first member 1 and the second member 2 to maintain a relatively vertical state.

[0080] In this embodiment, it also includes:

[0081] The key component 4, the second clamping part 201 and the second locking tooth 203 are provided with key holes 401, and the key holes 401 are provided with connecting holes corresponding to each slot 20304. The key component 4 is used to lift the locking component 10302 when rotating.

[0082] In this technical solution, the keyhole 401 extends from the right side of the second clamping part 201 to the left side to the slot 20304 near the leftmost side of the second locking tooth 203. The shape of the key piece 4 is adapted to the shape of the keyhole 401. When the key piece 4 is fully inserted into the keyhole 401, the four key teeth on the key piece 4 correspond to the positions of the four slots 20304 respectively. In this way, rotating the key piece 4 can push the snap-fit ​​piece 10302 in the slot 20304 upward to a state flush with the top surface of the main body 20301.

[0083] Similarly, a chamfer can be provided on the side of the key teeth of the key component 4 to improve the smoothness of the relative sliding of the first component 1 and the second component 2 when the key component 4 and the snap-fit ​​component 10302 are in action.

[0084] In this embodiment, the first locking tooth 103 further includes:

[0085] At least two elastic elements 10303 are respectively engaged in the grooves of two support elements 10301 and engaged in the downward action of the engagement element 10302.

[0086] In this technical solution, the elastic element 10303, i.e., the spring, is provided in two or more. At least one spring is engaged between the front support member 10301 and the engaging member 10302, and at least one spring is engaged between the rear support member 10301 and the engaging member 10302.

[0087] In this embodiment, the first clamping part 101 and / or the second clamping part 201 are provided with inclined extending guide holes, and the angle between the central axis of the guide hole and the side of the first clamping part 101 is 15°-60°.

[0088] In this technical solution, the left side of the first clamping part 101 has two guide holes facing to the right rear, and the right side of the second clamping part 201 has two guide holes facing to the left rear. The guide holes are horizontal or inclined vertically relative to the horizontal plane, and the angle between the axis of the guide hole and the vertical plane is 15°-60°. In some specific technical solutions, the angle between the axis of the guide hole and the vertical plane is 30° or 33°.

[0089] The guide hole serves a similar purpose to the first and second openings, enhancing the fixation between the component and the beam.
