Description
TECHNICAL FIELD
[0001] The present application relates to the field of housing, in particular to a building roof truss. BACKGROUND
[0002] In the construction industry, roof truss plays an indispensable role in the structure of the house, not only bearing the weight of the roof and the entire structure, but also effectively resisting various external forces such as wind load. The design, material selection and construction method of the roof truss have a decisive influence on the stability and long service life of the building.
[0003] With the continuous pursuit of space utilization efficiency in modern architectural concepts, large-span roof trusses are increasingly widely used and become the highlight in many architectural designs. However, the increase in the span of the roof truss also brings technical problems that cannot be ignored: under the influence of gravity, the lower chord of the large-span roof truss often appears to be significantly sagging. This not only damages the visual aesthetics of the building, but also may cause structural damage and weaken the load-bearing capacity of the roof truss. In addition, the stability of the large-span roof truss is particularly prominent when it faces complex and variable external environmental forces such as wind load and snow load. Design flaws or insufficient construction quality may cause the roof truss to lose stability under extreme weather conditions, thereby posing a serious challenge to the overall safety of the building. Therefore, how to effectively deal with the sagging and stability problems of large-span roof trusses has become a key technical issue that needs to be solved in the current construction field. CONTENT OF THE INVENTION
[0004] In order to make up for the above shortcomings, the present application provides a building roof truss to solve the problems raised in the background art.
[0005] To achieve the above purpose, the technical scheme adopted by the present application to solve its technical problems is:
[0006] A building roof truss, comprising four support columns and four bases integrally formed at the bottom ends of the support columns, two groups of support components are fixedly installed at the top inside of the four support columns, and four connecting components are bolted at the top ends, respectively, two roof components are welded on the four connecting components, the lower chord ends of the two roof components are connected to the top of the two groups of support components, and a plurality of purlins are welded at the top at equal intervals.
[0007] Further, the support component comprises two positioning blocks, an arched rod, two grooves and two protruding blocks, the outer walls of the two positioning blocks are integrally formed with the inner walls of the corresponding support columns, respectively, and two grooves are formed on the surfaces, respectively, the top of the arched rod is connected to the top of the lower chord end of the roof component, the bottom two ends of the arched rod are provided with two protruding blocks, respectively, and are bolted to the side walls of the corresponding support columns, and the two protruding blocks are connected to the interiors of the two grooves, respectively.
[0008] Furthermore, the connecting component includes a connecting block, a first plug-in slot and a second plug-in slot. The first plug-in slot is provided at the bottom of the connecting block, and the second plug-in slot is provided at the top of the side. The interior of the first plug-in slot is plugged into the corresponding top end of the support column and fixed with bolts. The interior of the second plug-in slot is plugged into one end of the roof component and seamlessly welded.
[0009] Furthermore, the roof component includes an I-beam, two oblique beams and several support rods. The bottom of the I-beam is connected to the top of the arch rod, and the two ends are respectively inserted into the corresponding second plug-in slots and seamlessly welded. The separated ends of the two oblique beams are respectively welded to the two ends of the I-beam surface, and the opposite ends are welded to each other. Several of the support rods are welded in a triangular shape between the I-beam and the two oblique beams.
[0010] Furthermore, the arch rod has reinforcing ribs inside, and the two ends of the surface respectively form a triangle with the two ends of the bottom of the I-beam and the corresponding support columns.
[0011] The utility model has the following beneficial effects:
[0012] 1. The roof truss of the present invention uses four support columns as the basic support structure. The bottom of each support column is equipped with an integrally formed base, which greatly enhances the overall stability of the roof truss. Secondly, the design of the supporting components is particularly critical. The arched rod not only enhances the load-bearing capacity of the roof truss, but also forms a stable triangular support structure through the top connection with the lower chord end of the roof component, further enhancing the stability of the roof truss and increasing the usable space within the roof truss. In addition, the roof component uses I-beams as the main load-bearing structure, supplemented by triangular supports formed by inclined beams and support rods. This design not only improves the strength of the roof truss, but also effectively disperses the load, ensuring the safety of the roof truss under extreme weather conditions.
[0013] 2. The design of the connecting components of this utility model makes the installation process of the roof truss simple and quick. Through the insertion slots and bolt fixing method, the connecting components can easily connect the support columns, support components and roof components together, greatly shortening the construction period. The snap-fit design of the protrusions and grooves in the support components not only enhances the connection strength between the components, but also facilitates positioning and alignment during installation, reducing the installation difficulty. The various components of the roof truss are connected by seamless welding, which not only improves the integrity of the roof truss but also reduces the safety hazards caused by loose connections.
[0014] 3. The internal reinforcement ribs of the arched rods further enhance their load-bearing capacity, making the roof truss safer and more reliable in extreme weather conditions such as strong winds and heavy snow. Furthermore, the triangular structure formed between the reinforced arched rods, the bottom ends of the I-beams, and the support columns not only improves the overall stability of the roof truss but also enhances its resistance to crosswinds.

DETAILED DESCRIPTION
[0023] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments.
[0024] Example:
[0025] See also Figure 1 、 Figure 2 、 Figure 4 、 Figure 6 A building roof truss includes four supporting columns 1 and a base 2 integrally formed at the bottom ends of the four supporting columns 1.
[0026] Four support columns 1 form the basic framework. Each of these four columns 1 is constructed of sturdy steel, ensuring it can withstand the weight of the building as well as the pressure of external factors such as wind, rain, and snow. Each support column 1 is integrally formed with a base 2 at its base end. This base 2 is designed to increase the contact area between the support column 1 and the ground, improving stability. It also allows the roof truss to be securely mounted to the ground using embedded bolts or other fixing methods.
[0027] See also Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 A building roof truss comprises four support columns 1, each with two sets of support components 3 fixedly mounted on top. Four connecting components 4 are bolted to the top of each column. Two roof components 5 are welded to the four connecting components 4. The lower chord ends of the two roof components 5 are connected to the tops of the two sets of support components 3, and several purlins 6 are welded to the tops at equal intervals. The support components 3 include two positioning blocks 31, an arched rod 32, two grooves 33, and two raised blocks 34. The connecting components 4 include a connecting block 41, a first insertion slot 42, and a second insertion slot 43. The roof component 5 includes an I-beam 51, two diagonal beams 52, and several support rods 53.
[0028] Among them, the support component 3 serves as a key component supporting the roof component 5. First, the two positioning blocks 31 are designed to fit tightly against the inner wall of the support column 1 and are connected to the support column 1 through an integral manufacturing process. This design ensures a secure connection between the positioning blocks 31 and the support column 1, thereby improving the stability of the entire roof truss. The outer surface of the positioning blocks 31 is provided with two grooves 33, the shape and size of which match the protrusions 34, which are used to achieve a snap-on connection during subsequent installation. The arch rod 32 is the core component of the support component 3 and is designed in an arched shape to provide greater structural strength and stability. The top of the arch rod 32 is connected to the lower chord end of the roof component 5. This connection ensures that the roof component 5 can be stably installed on the support component 3 and distributes the load on the roof component 5. The bottom end of the arch rod 32 has two protrusions 34, the shape and size of which match the grooves 33 on the positioning block 31. During installation, first align the positioning block 31 of the support component 3 with the inner wall of the support column 1 and connect them together by welding or other fixing methods. Then, align the protrusion 34 of the arch rod 32 with the groove 33 on the positioning block 31 and secure them together with bolts. This combination of clip-on and bolt-on fastening ensures a secure connection between the support component 3 and the support column 1, while providing additional stability and support. Finally, the lower chord end of the roof component 5 is placed on top of the arch rod 32. This connection method ensures that the roof component 5 is stably mounted on the support component 3 and can withstand external loads.
[0029] The connecting component 4 is responsible for the quick installation of the roof component 5 on the support column 1. The connecting block 41 is the main part of the connecting component 4, which is usually made of solid metal material. The shape and size of the connecting block 41 are designed to match the top end of the support column 1 and one end of the roof component 5 to ensure their tight connection. A first insertion slot 42 is opened at the bottom of the connecting block 41. The shape and size of this first insertion slot 42 match the top end of the support column 1, allowing the connecting block 41 to be connected to the support column 1 by insertion. During the insertion process, the first insertion slot 42 tightly fits the top end of the support column 1, and then they are fixed together by bolts. This combination of insertion and bolt fixation ensures the firm connection between the connecting component 4 and the support column 1. A second insertion slot 43 is opened at the side top of the connecting block 41. The shape and size of this second insertion slot 43 match one end of the I-beam 51, allowing the connecting component 4 to be connected to the roof component 5 by insertion. During the insertion process, the second insertion slot 43 tightly fits one end of the I-beam 51, and then they are connected together by seamless welding. This seamless welding connection ensures the firmness and durability between the connecting component 4 and the roof component 5. During the installation process, first, the first insertion slot 42 of the connecting component 4 is aligned with the top end of the support column 1, and they are fixed together by bolts. Then, one end of the roof component 5 is inserted into the second insertion slot 43 of the connecting component 4, and they are connected together by seamless welding. This connection not only ensures the firm connection between the connecting component 4 and the support column 1 and the roof component 5, but also provides additional stability and support.
[0030] The roof component 5 is a core component of the building's roof truss, responsible for bearing and distributing the roof's loads while providing the necessary structural strength and stability. The I-beam 51 is the primary load-bearing member of the roof component 5, its shape and dimensions designed to bear and distribute the roof's loads. The bottom of the I-beam 51 is braced against the top of the arched rod 32 in the support component 3. This connection ensures a stable installation of the roof component 5 on the support component 3. Simultaneously, the ends of the I-beam 51 are inserted into the corresponding second insertion slots 43 in the connecting blocks 41 and connected to the connecting component 4 via seamless welding. This seamless welding ensures the secure and durable connection between the roof component 5 and the connecting component 4. Two diagonal beams 52 serve as auxiliary load-bearing components of the roof component 5. They are welded to the ends of the I-beam 51, forming a stable triangular structure. The separated ends of the diagonal beams 52 are welded to the ends of the I-beam 51, while the opposite ends are welded together to form a closed triangular frame. This design not only enhances the structural strength of the roof component 5 but also its stability. Several support rods 53 are welded between the I-beam 51 and the two diagonal beams 52 to form a triangular support structure. The distribution and number of these support rods 53 are determined based on the size and load requirements of the roof component 5 to ensure that the roof component 5 can withstand and distribute the load while maintaining structural stability and durability. The support rods 53 are typically welded seamlessly to ensure the strength and durability of the joint. During installation, the bottom of the I-beam 51 of the roof component 5 is first aligned with the top of the arched rod 32 in the support component 3 and supported. Then, the two ends of the I-beam 51 are inserted into the corresponding second insertion slots 43 in the connecting component 4 and connected together using seamless welding. Next, the two diagonal beams 52 are welded to the ends of the surface of the I-beam 51 to form a stable triangular structure. Finally, several support rods 53 are welded between the I-beam 51 and the two diagonal beams 52 to form a triangular support structure.
[0031] The arch rod 32, a key element in the support component 3, is designed to provide additional support and stability while distributing the load on the roof component 5. To achieve this, reinforcing ribs are added to the interior of the arch rod 32. These ribs are typically made of a sturdy metal material and are distributed along the length of the arch rod 32. The addition of the ribs not only improves the bending and shear strength of the arch rod 32, but also enhances its overall structural stability. Furthermore, we paid special attention to the connection method between the ends of the surface of the arch rod 32 and the surrounding components. In the optimized design, the ends of the surface of the arch rod 32 form a triangle with the bottom ends of the I-beam 51 and the corresponding support column 1. This triangular connection method utilizes the stability principle of triangles and can significantly improve the structural strength and stability of the connection. The arch rod 32 forms two triangles with the support column 1 and the I-beam 51. These two triangular support structures are independent of each other but interrelated, and together constitute a stable support system for the entire building roof truss.
[0032] The purlins 6 increase the rigidity and stability of the roof, preventing it from deforming or collapsing under external loads such as wind or snow pressure. They also serve as a support structure for laying roof covering materials such as tiles and metal sheets, ensuring the integrity and durability of the roof.
[0033] The working principle of the building roof truss: The roof component 5 serves as the main load-bearing part of the roof truss, and the load on it is first transmitted through the I-beam 51. The I-beam 51, with its high strength and stable structure, can withstand vertical loads from the roof, such as its own weight, wind pressure, snow pressure, etc. The load is then transferred to the connecting block 41 through the seamless welding connection between the I-beam 51 and the connecting component 4. The connecting block 41 acts as a bridge, further transferring the load to the support column 1. As the main supporting structure of the roof truss, the support column 1 effectively distributes the received load to the foundation through its solid steel material and stable base 2. The internal reinforcement design and reasonable cross-sectional dimensions of the support column 1 ensure that it can withstand the load transferred from the roof component 5 and the connecting component 4 and maintain the stability of the structure. The support component 3 provides additional support and stability to the roof component 5 through the design of the arch rod 32. The arched structure of the arch rod 32 can disperse the load and reduce single-point stress, thereby improving the structural strength of the entire roof truss. The clamping and bolted connection between the arch rod 32 and the positioning block 31 and the protruding block 34 ensures a firm connection between the supporting component 3 and the supporting column 1, further enhancing the stability of the structure.
[0034] It should be noted that the specific model and specifications of the arch rod 32 need to be selected and determined according to the actual specifications of the device, and the specific selection calculation method adopts the existing technology in this field, so it will not be described in detail.
[0035] It will be apparent to those skilled in the art that the application is not limited to the details of the above-exemplified embodiments and that the present application can be implemented in other particular forms without departing from the spirit or essential characteristics thereof. The presently disclosed embodiments are, therefore, to be considered in all respects as illustrative and not restrictive, the scope of the application being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. No feature of the application is considered critical unless otherwise indicated in the claims.
