Description

Technical Field

[0001] This invention relates to the field of building engineering technology, particularly to purlin reinforcement structures and building roof structures. Background Technology

[0002] Steel purlins are key load-bearing components in the roofing system of steel structure buildings. They are laid along the roof slope and connected to the main structure such as roof trusses, steel frames, or steel beams. When subjected to excessive loads, purlins will undergo lateral bending deformation. Typically, tie rods are installed vertically between adjacent purlins to improve their load-bearing capacity. Currently, some problems exist in steel structure buildings, such as unreasonable quantity, specifications, and placement of tie rods, resulting in insufficient lateral stability of the purlins and affecting the overall stability of the building.

[0003] When reinforcing buildings, common methods include adding tie rods, changing the position of the original tie rods, using double purlins, and adding a double purlin section in the middle of the purlin.

[0004] However, adding tie rods or changing their positions requires drilling holes in the purlins. In particular, adjusting the position of the tie rods can result in an excessive number and concentration of holes in the purlins, which weakens their load-bearing capacity. In addition, drilling holes in the purlins at heights is time-consuming, labor-intensive, and time-consuming, which affects the factory's production efficiency.

[0005] Double-span purlins are either side-by-side or back-to-back, connected by welding or bolts. This method is costly in terms of materials, requires the removal of tie rods during construction, and bolt connections necessitate drilling holes in the purlins. Adding a double-span purlin section in the middle shares the same disadvantages as double-span purlins, and to ensure the purlin works in harmony with the original structural purlins, a steel-bonding process is often used, which is more complex and expensive. Summary of the Invention

[0006] The purpose of this section is to provide purlin reinforcement structures and building roof structures that can improve the load-bearing capacity of purlins without the need for drilling into the purlins, thus avoiding weakening the original purlin load-bearing capacity.

[0007] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a purlin reinforcement structure for reinforcing purlins, including purlin fixing members and longitudinal traction members. The purlin fixing members are used to snap onto the purlin, and there are at least two longitudinal traction members, with the two longitudinal traction members respectively connected above and below the purlin fixing members.

[0008] Preferably, the aforementioned purlin reinforcement structure includes: a purlin fixing member including a first snap-fit ​​member, at least two first snap-fit ​​members respectively disposed on both sides of the purlin, and at least two longitudinal traction members, with the two longitudinal traction members passing above and below the purlin respectively, and the longitudinal traction members being used to drive the two first snap-fit ​​members to clamp the purlin.

[0009] Preferably, in the aforementioned purlin reinforcement structure: the longitudinal traction member is connected to the first snap-fit ​​member through a locking structure; when there are multiple purlins, the longitudinal traction member passes through the first snap-fit ​​members on multiple purlins and is fixedly connected to the first snap-fit ​​members.

[0010] Preferably, the aforementioned purlin reinforcement structure includes a locking structure comprising a through hole on the first snap-fit ​​member, through which a longitudinal traction member passes, and a locking sleeve on the side of the first snap-fit ​​member, the locking sleeve being connected to the longitudinal traction member via a set screw.

[0011] Preferably, the aforementioned purlin reinforcement structure includes: when there are multiple purlins, an end traction member is also provided; at least four locking sleeves are provided on both sides of the first snap-fit ​​member corresponding to the second purlin on the outer edge; the inclined traction member passes through two of the upper and lower locking sleeves; and the end traction member passes through the other two upper and lower locking sleeves.

[0012] Preferably, the aforementioned purlin reinforcement structure includes a purlin fastener comprising a clamp one and a clamp two that engage with the purlin, wherein the clamp one or clamp two located on the side of the purlin is connected to the longitudinal traction member via a connector.

[0013] Preferably, the aforementioned purlin reinforcement structure has the following features: clamp one is U-shaped and has two threaded ends at its ends. The two threaded ends pass through clamp two and are fixed to clamp two by clamp two nuts. Clamp one passes through the connector.

[0014] Preferably, in the aforementioned purlin reinforcement structure, the connecting parts are U-shaped connecting parts or angle steel connecting parts, and the connecting parts located on the same side as the clamp are separated by spacers.

[0015] Preferably, in the aforementioned purlin reinforcement structure, when there are multiple purlins, the purlin fixing member corresponding to the second purlin on the outer edge is connected to the purlin on the outer edge side by an inclined traction member.

[0016] Preferably, the aforementioned purlin reinforcement structure includes at least two second fasteners and at least two third fasteners on both sides of the purlin. The second and third fasteners on the same side of the purlin are connected by a transverse traction member. The two second fasteners are fixed to the purlin by tension bolts, and the two third fasteners are fixed to the purlin by tension bolts. The tension bolts are fitted with intermediate sleeves.

[0017] Preferably, the aforementioned purlin reinforcement structure comprises: longitudinal traction components that are one or more combinations of wire rope, chain, and steel bar; inclined traction components that are one or more combinations of wire rope, chain, and steel bar; end traction components that are one or more combinations of wire rope, chain, and steel bar; and transverse traction components that are one or more combinations of wire rope, chain, and steel bar.

[0018] Building roof structure: including any of the purlin reinforcement structures described above.

[0019] The beneficial effects of this invention are: 1. By setting different types of snap-fit ​​components on both sides of the purlin and cooperating with different types of traction components to constrain the upper and lower flanges of the purlin, compared with the existing solution of inserting the traction components into the web of the purlin, the damage caused by drilling holes in the purlin is avoided, the out-of-plane deformation of the purlin is constrained more reliably, and the stability of the purlin is greatly improved.

[0020] 2. This solution has a wide range of applications and can be used in most situations. Since it does not require drilling holes in the purlins, it will not damage the original components, fundamentally saving construction costs and significantly reducing labor costs.

[0024] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0025] Numerous specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways than those described herein. The term "embodiment" as used herein refers to a particular feature, structure, or characteristic that may be included in at least one implementation of the invention. Example

[0026] Reference Figures 1-14 This embodiment provides a purlin reinforcement structure for reinforcing purlin 1. Specifically, it includes a purlin fastener for engaging with purlin 1, and at least two longitudinal traction members 2a, which are respectively connected above and below the purlin fastener. The purlin fastener in this embodiment includes a first engaging member 3 and longitudinal traction members 2a. There are at least two first engaging members 3, respectively located on both sides of the purlin 1. There are at least two longitudinal traction members 2a, which pass above and below the purlin 1, respectively. The longitudinal traction members 2a drive the two first engaging members 3 to clamp the purlin 1. The longitudinal traction members 2a are connected to the first engaging members 3 via a locking structure.

[0027] When there are multiple purlins 1, the longitudinal traction member 2a passes through the first locking member 3 on multiple purlins 1 and is fixedly connected to the first locking member 3. When there are multiple purlins 1, the first locking member 3 corresponding to the second purlin 1 on the outer edge is connected to the purlin 1 on the outer edge side through the inclined traction member 2b, and the inclined traction member 2b and the longitudinal traction member 2a are an integral structure. The locking structure includes a through hole on the first locking member 3, through which the longitudinal traction member 2a passes. The side of the first locking member 3 is provided with a locking sleeve 6, which is connected to the longitudinal traction member 2a through a set screw. When there are multiple purlins 1, an end traction member 2c is also provided. At least four locking sleeves 6 are provided on both sides of the first locking member 3 corresponding to the second purlin 1 on the outer edge. The inclined traction member 2b passes through two of the upper and lower locking sleeves 6, and the end traction member 2c passes through the other two upper and lower locking sleeves 6.

[0028] Both ends of the purlin 1 are fixedly connected to the steel beam. The purlin 1 is set parallel to the length of the steel beam. The height of the first snap-fit ​​3 is higher than the height of the purlin 1. The through hole is a round hole and is located at the upper and lower ends of the first snap-fit ​​3 near the edge. The end traction member 2c is fitted with a pressure member. The locking sleeve 6 is filled with structural adhesive to bond the locking sleeve 6 to the longitudinal traction member 2a, the inclined traction member 2b or the end traction member 2c to prevent the locking sleeve 6 from slipping. The inclined traction member 2b is not perpendicular to the purlin 1.

[0029] At least two second clamping members 4 and at least two third clamping members 5 are provided on both sides of the purlin 1. The second clamping members 4 and the third clamping members 5 located on the same side of the purlin 1 are connected by a transverse traction member 2d. Tensioning bolts 8 are provided between the two second clamping members 4 and between the two third clamping members 5. The tensioning bolts 8 are fitted with intermediate sleeves 7. The two ends of the transverse traction member 2d are respectively connected to the tensioning bolts 8 corresponding to the second clamping members 4 and the third clamping members 5.

[0030] One end of the transverse traction member 2d is fixed to the tension bolt 8 on the second clamping member 4 by a nut, and the other end of the transverse traction member 2d is connected to the tension bolt 8 on the third clamping member 5 by a wire rope tensioner. The transverse traction member 2d is parallel to the length direction of the purlin 1.

[0031] The height of the second clamping member 4 and the third clamping member 5 is higher than that of the purlin 1. The second clamping member 4 has round holes at both ends near the edge. The second clamping member 4 also has through holes for inserting tension bolts 8. An intermediate sleeve 7 is fitted on the tension bolt 8. The two ends of the intermediate sleeve 7 are in contact with the side of the second clamping member 4. The third clamping member 5 has at least two through holes for inserting tension bolts 8. An intermediate sleeve 7 is fitted on one of the tension bolts 8. One end of the intermediate sleeve 7 is in contact with the side of the third clamping member 5, and the other end is in contact with the inner wall of the purlin 1.

[0032] The longitudinal traction component 2a is one or more of wire rope, chain, and steel bar; the inclined traction component 2b is one or more of wire rope, chain, and steel bar; the end traction component 2c is one or more of wire rope, chain, and steel bar; and the transverse traction component 2d is one or more of wire rope, chain, and steel bar.

[0033] Typically, the longitudinal traction component 2a uses a single wire rope, but combinations of wire rope and chain, wire rope and steel bar, or chain and steel bar can also be used. The inclined traction component 2b, the end traction component 2c, and the lateral traction component 2d also typically use a single wire rope, or combinations of the above methods can be used.

[0034] In use, firstly, place the first snap-fit ​​member 3 at the corresponding positions on both sides of the purlin 1. Then, insert the longitudinal traction member 2a sequentially into the round hole on the first snap-fit ​​member 3, and simultaneously insert the locking sleeve 6 on both sides of the first snap-fit ​​member 3. When the longitudinal traction member 2a is inserted between the two outermost purlins 1, connect the longitudinal traction member 2a obliquely to the end of the purlin 1. Then, use the set screw to fix the locking sleeve 6, thereby pressing the first snap-fit ​​member 3. Add an end traction member 2c perpendicular to the length direction of the purlin 1 between the two outermost purlins 1. Based on the above scheme, fix the second snap-fit ​​member 4 and the third snap-fit ​​member 5 to both sides of the purlin 1, and connect the transverse traction member 2d between the second snap-fit ​​member 4 and the third snap-fit ​​member 5. The transverse traction member 2d acts as a downward-rotating tension member, further improving the bending load-bearing capacity of the purlin 1. Example

[0035] like Figures 15 to 17 As shown, the purlin fixing member in this embodiment includes clamp 9 and clamp 91 that are engaged with purlin 1. The clamp 9 or clamp 91 located on the side of purlin 1 is connected to the longitudinal traction member 2a through a connector.

[0036] The first clamp 9 is U-shaped and has two threaded ends. The second clamp 91 can be a plate-like structure with at least two through holes through which the first clamp 9 passes. The two threaded ends pass through the second clamp 91 and are pressed against the purlin by the second clamp nut 91a. The second clamp 91 is preferably located at the lower end of the purlin.

[0037] In this embodiment, the connecting parts are either U-shaped connecting parts 92 or angle steel connecting parts 92b. Generally, when clamp 9 is connected to longitudinal traction member 2a, U-shaped connecting parts 92 are used. The interior of U-shaped connecting parts 92 is connected to longitudinal traction member 2a through longitudinal traction member nut 2a1. When clamp 9 is connected to inclined traction member 2b, angle steel connecting parts 92b are used. Angle steel connecting parts 92b are connected to inclined traction member 2b through longitudinal traction member bolt 2a2. Since the purlin is reinforced by the tension of the traction member, a certain distance must be maintained between the connecting parts located on the same side of clamp 9. Therefore, the two connecting parts can be separated by spacer 92a.

[0038] It should be noted that the purlin fastener described in this embodiment can also be used in conjunction with the connecting fastener in Embodiment 1, and can also be used in conjunction with the inclined traction member 2b and the transverse traction member 2d described in Embodiment 1.

[0039] The present invention also discloses a building roof structure, including the purlin reinforcement structure of the two embodiments described above.

[0040] Compared to existing technologies, when the purlin 1 in a building has insufficient bending capacity, the purlin reinforcement structure of this application can fully utilize the characteristics of the reinforcement material (tensile strength of the steel wire), reduce construction steps, reduce material usage, and increase construction speed. This structure can be used alone to improve the stability of purlin 1, or it can be used as a whole system to simultaneously increase stability and bending capacity. Compared with currently commonly used solutions, it reduces costs, significantly shortens high-altitude work time, eliminates the need for large component construction, and improves overall operational safety.

[0041] Importantly, although only a few embodiments are described in detail in this disclosure, those who consult this disclosure will readily understand that many modifications are possible without substantially departing from the subject matter described in this application, such as variations in the size, structure, shape, and proportions of various elements, as well as temperature, pressure, installation arrangement, use of materials, color, orientation, etc.; for example, an element shown as integrally formed may be composed of multiple parts or elements, and the position of the elements may be inverted or otherwise changed; therefore, all such modifications should be included within the scope of the invention, and other substitutions, modifications, alterations, and omissions may be made in the design, operation, and arrangement of the exemplary embodiments without departing from the scope of the invention.
