Description

Technical Field

[0001] This utility model relates to the field of steel structure technology, and more specifically, to an adjustable steel structure herringbone beam connection device. Background Technology

[0002] A gable roof, also known as a pitched roof, presents a triangular roof shape, which helps the stability and drainage of the building, while also making the house more beautiful and diverse. It is widely used in construction, and the main types are single-slope, double-slope, and zigzag. The form and slope of the gable roof mainly depend on factors such as the building plan, structural shape, roofing material, climate, customs, and architectural style.

[0003] Currently, most A-frame beams are connected to steel structural supports by welding, which is inconvenient for both installation and disassembly. During installation, hoisting equipment is required to precisely lift them to the designated position, making subsequent alignment difficult. This increases the overall construction difficulty and requires frequent movement, re-lifting, and re-releasing of the A-frame beams, resulting in less than ideal overall performance.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] To address the shortcomings of existing technologies, this utility model provides an adjustable steel structure chevron beam connection device, which has the advantages of convenient connection, easy adjustment, and easy assembly positioning, thereby solving the problems mentioned in the background technology.

[0007] (II) Technical Solution

[0008] To achieve the advantages of convenient connection, easy adjustment, and easy assembly positioning, the specific technical solution adopted by this utility model is as follows:

[0009] An adjustable steel structure chevron connection device includes a chevron body and a mounting base. The mounting base is symmetrically welded to both sides of the top of the chevron body. Mounting plates are symmetrically installed on both sides inside the mounting base. Several sets of rollers are evenly rotatably connected to the inner surface of the mounting plate. Limiting rods are symmetrically installed at both ends of the outer surface of the mounting plate, and the limiting rods are slidably connected to the mounting base. An adjusting screw is rotatably connected to the middle of the outer surface of the mounting plate, and one end of the adjusting screw is threaded to the mounting base.

[0010] Furthermore, a fixing plate is symmetrically installed in the middle of the mounting base, and a tube is installed through the surface of the fixing plate. A limiting plate is installed on one side of the tube inside the mounting base, and an adjustment groove is opened on the outer periphery of the limiting plate inside the mounting base. A spring is sleeved on one side of the limiting plate on the outer periphery of the tube, and the spring is fixed to the surface of the limiting plate and the inner wall of the adjustment groove. A mounting cylinder is installed on the outer side of the mounting base at a position flush with the tube.

[0011] Furthermore, the mounting base has a support plate secured inside by high-strength bolts.

[0012] Furthermore, the support plate has fastening holes on its surface for inserting the insert cylinder.

[0013] Furthermore, both the insert and the mounting cylinder are hollow structures.

[0014] Furthermore, the surface of the limiting disc is provided with a through hole.

[0015] Furthermore, the rotation direction of the roller is adapted to the movement direction of the main body of the herringbone beam during installation.

[0016] Furthermore, the diameter of the insert is the same as the inner diameter of the fastening hole.

[0017] (III) Beneficial Effects

[0018] Compared with the prior art, this utility model provides an adjustable steel structure herringbone beam connection device, which has the following advantages:

[0019] (1) This utility model uses rollers. When installing the steel structure A-beam, hoisting equipment can be used to lift it to the specified height first. Then, the mounting seat at the bottom is placed on the surface of the support plate and it is in a relatively aligned state. Then, the adjusting screw can be rotated so that the roller on the surface of the mounting plate contacts the support plate. At this time, the A-beam can be easily moved by the rolling of the roller. Compared with the traditional secondary hoisting and release, it can effectively reduce the labor intensity and facilitate better connection and adjustment. The whole adopts a detachable design, so it can be flexibly loaded and unloaded to adjust the installation position and improve the overall use effect. It has the advantages of convenient connection and easy adjustment.

[0020] (2) This utility model uses a plug and a fastening hole. When the mounting base moves, the support plate will squeeze the fixing plate in the middle position, which will cause the internal spring to deform and the fixing plate to move outward as a whole. As the movement continues, the plug on the surface of the fixing plate will align with the fastening hole on the surface of the support plate. At this time, the spring can be reset by deformation to drive the plug into the fastening hole, realizing the pre-fixing operation of the A-beam body and the support plate. Then, the personnel can pass the high-strength bolts required for fastening through the mounting cylinder, the limiting plate, the plug and the mounting plate in sequence and expose them from the mounting cylinder on the other side. At this time, the personnel can install the nuts to realize the fastening operation of the structure. It has the advantage of assembly positioning. Attached Figure Description

[0028] To further illustrate the various embodiments, the present invention provides accompanying drawings, which are part of the disclosure of the present invention. These drawings are mainly used to illustrate the embodiments and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these contents, those skilled in the art should be able to understand other possible implementation methods and the advantages of the present invention. The components in the figures are not drawn to scale, and similar component symbols are usually used to represent similar components.

[0029] According to an embodiment of the present invention, an adjustable steel structure herringbone beam connection device is provided.

[0030] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments, such as... Figure 1-4 As shown, an adjustable steel structure herringbone beam connection device according to an embodiment of the present invention includes a herringbone beam body 1 and a mounting base 2. The mounting base 2 is symmetrically welded to both sides of the top of the herringbone beam body 1. Mounting plates 8 are symmetrically installed on both sides inside the mounting base 2. Several sets of rollers 6 are evenly rotatably connected to the inner surface of the mounting plates 8. Limiting rods 3 are symmetrically installed at both ends of the outer surface of the mounting plates 8, and the limiting rods 3 are slidably connected to the mounting base 2. An adjusting screw 4 is rotatably connected to the middle of the outer surface of the mounting plates 8. One end of the adjusting screw 4 is threadedly connected to the mounting base 2. When the mounting base 2 is sleeved on the support plate 5, the rollers 6 form rolling friction after contacting the support plate 5, reducing the pushing resistance and facilitating more effortless and convenient position adjustment. The sliding cooperation between the limiting rods 3 and the mounting base 2 ensures that the mounting plate 8 moves linearly without deviation.

[0031] In one embodiment, a fixing plate 14 is symmetrically installed in the middle of the mounting base 2. A plug 15 is installed through the surface of the fixing plate 14. A limiting plate 10 is installed on one side of the plug 15 inside the mounting base 2. An adjustment groove 11 is opened on the outer periphery of the limiting plate 10 inside the mounting base 2. A spring 9 is sleeved on one side of the limiting plate 10 on the outer periphery of the plug 15. The spring 9 is fixed to the surface of the limiting plate 10 and the inner wall of the adjustment groove 11. A mounting cylinder 12 is installed on the outer side of the mounting base 2 at the same level as the plug 15. When the mounting base 2 moves to the support plate 5, the spring 9 is compressed and stores energy. After the plug 15 is aligned with the fastening hole 7, the spring 9 releases energy and pushes the plug 15 into the hole to achieve the pre-fixation operation of the structure. When it needs to be removed later, the fixing plate 14 only needs to be moved in the opposite direction. The spring 9, high-strength screw and nut used in this application can be selected according to the actual needs, and will not be described in detail here.

[0032] In one embodiment, the support plate 5 is secured to the interior of the mounting base 2 by high-strength bolts.

[0033] In one embodiment, a fastening hole 7 is provided on the surface of the support plate 5 for inserting the insert 15. The fastening hole 7 is provided to facilitate the pre-fixing operation of the A-frame beam body 1.

[0034] In one embodiment, both the insert 15 and the mounting cylinder 12 are hollow structures, and the bolts can pass through the mounting cylinder 12 and the support plate 5 of the insert 15 in sequence to achieve simultaneous locking on both sides, thereby improving installation efficiency.

[0035] In one embodiment, the surface of the limiting plate 10 is provided with a through hole 13. By setting the through hole 13 and the insert 15 at the same level, blind operation errors can be reduced when aligning with the fastening hole 7.

[0036] In one embodiment, the rotation direction of the roller 6 is adapted to the movement direction of the herringbone beam body 1 during installation. The setting of the roller 6 to the movement direction of the herringbone beam body 1 is to ensure that the roller 6 can roll smoothly, thereby assisting the herringbone beam in moving to achieve position adjustment, making it easier to align the structure.

[0037] In one embodiment, the diameter of the insert 15 is the same as the inner diameter of the fastening hole 7. The size is set to ensure that the insert 15 can be smoothly inserted into the fastening hole 7, thereby realizing the pre-fixation operation of the structure and facilitating the installation and use of bolts. The size of the bolt matches the inner diameter of the insert 15.

[0038] Working Principle: In actual use, personnel can use hoisting equipment to lift the main body 1 of the A-beam onto the support plate 5, so that the mounting base 2 at its bottom can fit onto the outer top of the support plate 5. At this time, the two can be relatively aligned. Then, by rotating the adjusting screw 4, the rollers 6 on the surface of the mounting plate 8 can be driven to fit against the surface of the support plate 5. With the assistance of the rollers 6, personnel can easily push the main body 1 of the A-beam, so that it can be level with the support plate 5. Compared with the traditional secondary hoisting and release method, it can significantly reduce the labor intensity of personnel and facilitate faster installation and connection. Moreover, when the mounting base 2 moves, the support plate 5 will compress the fixing plate 14 in the middle position, thereby causing the internal spring 9 to deform. This causes the fixing plate 14 to move outward as a whole. As the movement continues, the insert 15 on the surface of the fixing plate 14 will align with the fastening hole 7 on the surface of the support plate 5. At this time, the spring 9 can be deformed and reset to drive the insert 15 into the fastening hole 7, realizing the pre-fixation operation between the A-beam body 1 and the support plate 5. Then, the personnel can pass the high-strength bolts required for fastening through the mounting cylinder 12, the limiting plate 10, the insert 15 and the mounting plate 8 in sequence, and expose them from the mounting cylinder 12 on the other side. At this time, the personnel can install the nuts, thereby realizing the fastening operation of the structure. Since the whole adopts a detachable design, it can be flexibly installed and disassembled to adjust the installation position and improve the overall use effect. The device as a whole has the advantages of convenient connection, easy adjustment and assembly positioning.
