Description

Technical Field

[0001] This invention relates to the field of truss structure construction technology, and in particular to a truss and a truss construction method. Background Technology

[0002] Truss structures are a common type of building structure. Because multiple members in a truss can form multiple triangular structures, trusses possess excellent load-bearing capacity. In existing technologies, for large trusses, construction workers typically hoist multiple truss members to a predetermined height and then assemble them into a truss high in the air. The construction process requires the use of scaffolding to support the truss or parts of its members. Existing technologies for large trusses require a large number of scaffolding units, resulting in low construction efficiency and high construction costs. Summary of the Invention

[0003] The present invention aims to at least solve one of the technical problems existing in the prior art. To this end, the present invention proposes a truss that is easy to assemble, requires fewer jigs during the assembly process, and is beneficial for saving truss construction costs and improving truss construction efficiency.

[0004] The present invention also proposes a truss construction method.

[0005] A truss according to a first aspect of the present invention includes: a lower chord, arranged laterally, the lower chord having opposing start and end ends; a straight web member, arranged vertically, the bottom end of the straight web member connected to the start end; and multiple truss modules, the multiple truss modules being distributed along the length direction of the lower chord, each truss module including an upper segment and a first diagonal web member, the upper segment being arranged laterally, one end of the upper segment being connected to the top end of the first diagonal web member, and the included angle between the upper segment and the first diagonal web member being acute. The upper chord is formed by connecting multiple upper segments belonging to different truss modules end to end. The upper chords are spaced above the lower chords. One end of each upper chord is connected to the top of the straight web member. The bottom end of the first diagonal web member is connected to the lower chord. Multiple second diagonal web members are provided. The top of each second diagonal web member is connected to an upper segment. From the starting end to the ending end, the first and second diagonal web members are alternately arranged, and their inclination directions are opposite.

[0006] A truss construction method according to a second aspect of the present invention includes the following steps: installing the lower chord to the top of the jig and positioning the lower chord laterally; connecting the bottom of the straight web member to the starting end of the lower chord and positioning the straight web member vertically; and alternately installing the truss module and the second diagonal web member on the lower chord along a direction from the starting end to the ending end.

[0007] According to some embodiments of the present invention, the truss construction method further includes: assembling the truss module before installing the truss module onto the lower chord; assembling the truss module includes the following steps: supporting the first diagonal web member with a support frame, so that the first diagonal web member is inclined; hoisting the upper section above the first diagonal web member, and setting the upper section laterally; connecting one end of the upper section to the top end of the first diagonal web member.

[0008] According to some embodiments of the present invention, the lower chord includes a plurality of lower chord segments connected end to end in sequence, and the lower chord also includes a first connector connected to the lower chord segments. The first diagonal brace and the second diagonal brace can both be connected to the first connector. Installing the lower chord onto the top of the frame includes the following steps: setting up a plurality of frames, and distributing the plurality of frames at intervals in the horizontal direction; having the plurality of frames jointly support the lower chord, and having each first connector located above one of the frames.

[0009] According to some embodiments of the present invention, installing the truss module for connection with the straight web member onto the lower chord includes the following steps: using a crane to lift the truss module to a preset height; maintaining the connection between the crane and the truss module, welding the bottom end of the first diagonal web member to the lower chord member, and welding the upper section to the top end of the straight web member; and disconnecting the connection between the crane and the truss module.

[0010] According to some embodiments of the present invention, installing the truss module, which is spaced apart from the straight web member, onto the lower chord includes the following steps: using a crane to lift the truss module to a preset height; maintaining the connection between the crane and the currently lifted truss module, welding the currently lifted truss module to the truss module already installed on the lower chord, and welding the currently lifted truss module to the lower chord; and disconnecting the crane from the truss module currently connected to the crane.

[0011] According to some embodiments of the present invention, installing the second diagonal brace onto the lower chord includes the following steps: using a crane to lift the second diagonal brace to a preset height; maintaining the connection between the crane and the second diagonal brace, welding the top end of the second diagonal brace to the upper segment, and welding the bottom end of the second diagonal brace to the lower chord; and disconnecting the connection between the crane and the second diagonal brace.

[0012] According to some embodiments of the present invention, installing the lower chord to the top of the tire frame includes the following steps: installing a pad on the top of the tire frame; and placing the lower chord above the pad.

[0013] The truss and truss construction method of the present invention have at least the following beneficial effects: Since the upper chord of the truss is formed by connecting multiple upper segments belonging to different truss modules, during the truss assembly process, after the first diagonal web member of the truss module is fixed to the lower chord, the truss module can be fixed relative to the lower chord, and the upper segments can also be fixed. As the number of trusses installed on the lower chord increases, the upper chord gradually takes shape. Therefore, apart from the jig used to support the lower chord, no additional jigs are needed to support the upper chord or upper segments when assembling the truss. This helps to reduce the number of jigs required during truss construction, thereby improving the ease of truss construction and reducing truss construction costs.

[0014] Additional aspects and advantages of the invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

The use of "first" and "second" in the description is merely for distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the number of indicated technical features, or implicitly indicating the order of the indicated technical features.

[0035] In the description of this invention, unless otherwise explicitly defined, terms such as "set up," "install," and "connect" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this invention in conjunction with the specific content of the technical solution.

[0036] Figure 1 ,as well as Figures 3 to 8 A truss according to an embodiment of the present invention is shown. The truss includes a lower chord 103, truss modules 205, straight web members 106, and a second diagonal web member 105. Multiple truss modules 205 are provided in the truss, and the multiple truss modules 205 are distributed along the length direction of the lower chord 103, such as... Figure 6 As shown, the truss module 205 includes a first diagonal web member 104 and an upper section 206.

[0037] contrast Figure 5 and Figure 6 It can be seen that the truss module 205 is shaped like a "7", with the upper segment 206 arranged laterally. One end of the upper segment 206 is connected to the top of the first diagonal web member 104, and the angle between the upper segment 206 and the first diagonal web member 104 is an acute angle. The lateral arrangement of the upper segment 206 specifically refers to its horizontal orientation; in other embodiments, the upper segment 206 may also be inclined, in which case the lateral arrangement of the upper segment 206 means that the angle between the upper segment 206 and the horizontal plane is less than twenty degrees. The definition of the lateral arrangement of other segments or members in this invention is the same as that of the lateral arrangement of the upper segment 206, and will not be repeated below. (Comparison) Figure 1 and Figure 8 It can be seen that multiple upper rod segments 206 belonging to different truss modules 205 are connected end to end in sequence to form the upper chord 102.

[0038] The lower chord 103 is arranged horizontally, and is spaced below the upper chord 102. For example... Figure 5 As shown, the lower chord 103 includes multiple lower chord segments 201 connected end-to-end in sequence; furthermore, the lower chord 103 also includes an end connector 207, which is connected to one of the lower chord segments 201 and is located at one end of the lower chord 103. The bottom end of the straight web member 106 is connected to one end of the lower chord 103; specifically, the bottom end of the straight web member 106 is connected to the end connector 207. Figure 5 andFigure 6 The top end of the straight web member 106 is used to connect to the upper segment 206 of the first truss module 205, thereby realizing the connection between the top end of the straight web member 106 and one end of the upper chord member 102.

[0039] like Figure 1 As shown, the first oblique web member 104 and the second oblique web member 105 are both located between the upper chord member 102 and the lower chord member 103. The bottom ends of both the first oblique web member 104 and the second oblique web member 105 are connected to the lower chord member 103, and the top ends of both the second oblique web member 105 and the first oblique web member 104 are connected to the upper chord member 102. Moreover, for an adjacent first oblique web member 104 and a second oblique web member 105, their inclination directions are opposite. In this invention, the opposite inclination directions of the first oblique web member 104 and the second oblique web member 105 mean that if the top end of the first oblique web member 104 is to the left of the bottom end of the first oblique web member 104, then the top end of the second oblique web member 105 is to the right of the bottom end of the second oblique web member 105; if the top end of the first oblique web member 104 is to the right of the bottom end of the first oblique web member 104, then the top end of the second oblique web member 105 is to the left of the bottom end of the second oblique web member 105.

[0040] If the end of the lower chord 103 used to connect to the straight web member 106 is called the starting end (the starting end corresponds to the left end of the lower chord 103 in the attached drawing), and the end of the lower chord 103 opposite to the starting end is called the ending end (the ending end corresponds to the right end of the lower chord 103 in the attached drawing), then in the direction from the starting end to the ending end, the first oblique web member 104 and the second oblique web member 105 are alternately arranged (e.g., Figure 8 As shown). Figure 8 As shown, the alternating arrangement of the first oblique web member 104 and the second oblique web member 105 means that from the starting end to the ending end, there is a first oblique web member 104 between two adjacent second oblique web members 105, and there is a second oblique web member 105 between two adjacent first oblique web members 104.

[0041] Based on the above-mentioned truss, the present invention provides a truss construction method, referring to... Figure 2 The construction method includes the following steps:

[0042] S10: Install the lower chord 103 onto the top of the frame 101, and position the lower chord 103 horizontally;

[0043] S20: Connect the bottom of the straight web member 106 to the starting end of the lower chord member 103, and make the straight web member 106 vertically set;

[0044] S30: Along the direction from the starting end to the ending end, alternately install truss modules 205 and second diagonal web members 105 on the lower chord 103.

[0045] The jig 101 mentioned in the above method can be understood as a support for load-bearing. The jig 101 is a commonly used auxiliary tooling in the construction field. The structure of the jig 101 is not specifically described in this invention. Figures 3 to 8 As shown, multiple support frames 101 can be provided for supporting the truss, and the multiple support frames 101 are spaced apart in the horizontal direction. After the truss is assembled and fixed to other parts of the building, the support frames 101 are removed, so that the truss can be used as a cantilever truss.

[0046] The above methods can be combined Figures 3 to 8 To understand. Figure 3 This is a schematic diagram of the jig frame 101; after the lower chord 103 is installed on top of the jig frame 101 (i.e., after completing step S10), the relative position between the lower chord 103 and the jig frame 101 is as follows. Figure 4 As shown, (the lower chord 103 includes an end connector 207 and multiple lower chord segments 201). In Figure 4 Based on this, after connecting the straight web member 106 to the lower chord member 103 (i.e., after completing step S20), the state of the lower chord member 103 and the straight web member 106 is as follows: Figure 5 As shown. The installation of truss module 205 and second diagonal brace 105 in step S30 is described below. Please refer to the following instructions in sequence. Figure 5 and Figure 6 After the straight web member 106 is installed, the installer can first hoist a truss module 205 above the lower chord 103, then connect the upper section 206 of the truss module 205 to the top of the straight web member 106, and connect the bottom end of the first diagonal web member 104 of the truss module 205 to the lower chord 103. In this way, the truss module 205 can be relatively fixed to the lower chord 103 and the straight web member 106. Then refer to the following steps... Figure 6 and Figure 7 After the first truss module 205 is installed, the workers will hoist a second diagonal web member 105 above the lower chord 103. Next, the bottom end of the second diagonal web member 105 will be connected to the lower chord 103, and the top end of the second diagonal web member 105 will be connected to the upper section 206 of the truss module 205.

[0047] After completing the installation of the first truss module 205 and the first second diagonal web member 105, the remaining truss modules 205 and second diagonal web members 105 are installed alternately. After installing multiple truss modules 205 and multiple second diagonal web members 105, the truss will be in the following state: Figure 8 As shown. It should be noted that, in conjunction with... Figure 7 and Figure 8Except for the first truss module 205 (the truss module 205 connected to the straight web member 106), the remaining truss modules 205 are actually connected to the truss modules 205 installed in the previous round during installation, rather than to the straight web member 106.

[0048] In existing technologies, to assemble a truss, it is typically necessary to first support the upper chord 102 and lower chord 103 using a jig 101, and then install diagonal web members between the upper chord 102 and lower chord 103. However, this invention does not first support the upper chord 102 above the lower chord 103 using a jig 101. Instead, it assembles multiple upper chord segments 206 into the upper chord 102 by splicing truss modules 205. This construction method eliminates the need for the jig 101 used to support the upper chord 102, thereby reducing the number of jigs 101 used during construction, thus saving on truss construction costs and improving truss construction efficiency.

[0049] Further details regarding the construction method of this invention will be provided below.

[0050] like Figure 3 As shown, in one embodiment, the lower chord 103 includes a plurality of lower chord segments 201, each lower chord segment 201 including a first connector 202. The first connector 202 includes a first welded section 203 and a second welded section 204, the bottom ends of the first welded section 203 and the second welded section 204 are connected, and the top ends of the first welded section 203 and the top ends of the second welded section 204 are spaced apart, thereby making the first connector 202 V-shaped. Figure 8 As shown, the first welding section 203 is used to weld to the bottom end of the first diagonal web member 104 of the truss module 205, and the second welding section 204 is used to weld to the bottom end of the second diagonal web member 105.

[0051] In the case where the lower chord 103 includes multiple lower chord segments 201, in one embodiment, the step S10 mentioned above, "installing the lower chord 103 onto the top of the frame 101," specifically includes the following steps:

[0052] S101: Multiple tire frames 101 are provided, and the multiple tire frames 101 are distributed at intervals in the horizontal direction (e.g., Figure 3 (as shown);

[0053] S102: Multiple support frames 101 share the load of the lower chord 103, and each first connector 202 is positioned above a support frame 101 (e.g., Figure 5 (As shown).

[0054] Since the first connector 202 is used to connect the first diagonal web member 104 and the second diagonal web member 105, the first connector 202 is located at the stress concentration point of the lower segment 201. Positioning the first connectors 202 above each of the formwork 101 means that the formwork 101 can support the stress concentration point of the lower segment 201. This improves the overall support effect of the formwork 101 on the lower chord 103 and enhances the safety during truss construction.

[0055] In one embodiment, "installing the lower chord 103 onto the top of the frame 101" further includes the following steps: first, installing a pad (not shown) on the top of the frame 101, and then placing the lower chord 103 on top of the pad. Installing the pad on the top of the frame 101 facilitates adjustment of the elevation of the lower chord 103 to meet the truss position requirements. It should be noted that the installer can also adjust the thickness or number of pads to meet the elevation requirements of the lower chord 103.

[0056] Before installing the truss module 205 onto the lower chord 103, the truss module 205 needs to be fabricated first. The order of assembling the truss module 205 with steps S10 and S20 is not strictly required; for example, the truss module 205 can be assembled after step S20 or before step S10. In one embodiment, assembling the truss module 205 specifically includes the following steps:

[0057] S01: The first inclined web member 104 is supported by the support frame 303, so that the first inclined web member 104 is set at an angle.

[0058] S02: Hoist the upper pole section 206 above the first inclined web member 104, and make the upper pole section 206 horizontally positioned;

[0059] S03: Connect one end of the upper rod segment 206 to the top of the first diagonal web member 104.

[0060] The process of assembling truss module 205 can be combined Figures 9 to 11 To understand this, the support frame 303 used in the assembled truss module 205 is different from the jig 101 used to support the lower chord 103. After the support frame 303 supports the first diagonal web member 104 (corresponding to step S01), the state of the first diagonal web member 104 is as follows: Figure 9 As shown, the ground 304 abuts against the bottom end of the first diagonal brace 104, while the support frame 303 abuts against the side of the first diagonal brace 104 to support it. Subsequently, the construction worker can use a crane to lift the upper section 206 above the first diagonal brace 104 (e.g., ...). Figure 10 (As shown), then one end of the upper rod segment 206 is connected to the top end of the first diagonal web member 104 (as shown). Figure 11(As shown in the attached figure). The entire crane is not shown in the attached figure; only the crane's hook 301 is shown. The hook 301 hooks the rope 302, which is also connected to the truss module 205. When the hook 301 rises, it can lift the truss module 205. During step S03, the worker temporarily connects the upper rod segment 206 to the first diagonal web member 104. Subsequently, during step S30, the upper rod segment 206 and the first diagonal web member 104 are welded together. The temporary connection method can be referred to... Figure 11 The construction worker can install a temporary connecting plate 306 and two manual hoists 305. The manual hoists 305 pull the upper pole section 206 and the first diagonal brace 104. The temporary connecting plate 306 is connected to the upper pole section 206 and the first diagonal brace 104 by bolts. (Refer to...) Figure 12 After the truss module is assembled, the construction workers can use a crane to lift the entire truss module 205, separating it from the support frame 303. After separation, the truss module 205 will be hoisted above the lower chord 103 (e.g., Figure 6 (As shown).

[0061] In the case where the upper chord 102 is composed of multiple upper chord segments 206, each upper chord segment 206 includes a second connector 208. For example... Figure 10 As shown, the second connector 208 is also V-shaped, and includes a third welding section 209 and a fourth welding section 210. The third welding section 209 is used for welding to the top end of the first diagonal web member 104, and the fourth welding section 210 is used for welding to the top end of the second diagonal web member 105.

[0062] In this invention, the connection method between different rods or segments can all be set as welding. In one embodiment, the truss module 205 (for connection with the straight web member 106) Figures 6 to 8 The first truss module 205 (counting from left to right) is installed onto the lower chord 103, which can be achieved through the following steps:

[0063] S301: Use a crane to lift the truss module 205 to the preset height;

[0064] S302: Maintain the connection between the crane and the truss module 205, weld the bottom end of the first diagonal web member 104 to the lower chord member 103, and weld the upper section 206 to the top end of the straight web member 106;

[0065] S303: Disconnect the crane from the truss module 205.

[0066] In the above configuration, during the welding process of truss module 205 with lower chord 103 and straight web member 106, the crane remains connected to truss module 205, and the crane provides a certain degree of support for truss module 205. The construction worker does not need to use an additional jig 101 to support truss module 205.

[0067] Similarly, the truss module 205, which is spaced apart from the straight web member 106, can be installed onto the lower chord member 103 through the following steps:

[0068] S304: Use a crane to lift the truss module 205 to the preset height;

[0069] S305: Maintain the connection between the crane and the truss module 205 currently connected to the crane, weld the truss module 205 currently being lifted by the crane to the truss module 205 already installed on the lower chord 103, and weld the truss module 205 currently being lifted by the crane to the lower chord 103.

[0070] S306: Disconnect the crane from the truss module 205 currently connected to the crane.

[0071] Similarly, the installation of the second diagonal web member 105 can be achieved through the following steps:

[0072] S307: Use a crane to lift the second diagonal brace 105 to the preset height;

[0073] S308: Maintain the connection between the crane and the second diagonal web member 105, weld the top end of the second diagonal web member 105 to the upper section 206, and weld the bottom end of the second diagonal web member 105 to the lower chord 103.

[0074] S309: Disconnect the crane from the second diagonal brace 105.

[0075] The advantage of installing the second diagonal web member 105 through steps S307 to S309 is that the crane provides a certain degree of support for the second diagonal web member 105, eliminating the need for support from the jig 101.
