Description

Technical Field

[0001] The invention belongs to the technical field of steel beam supports, and in particular relates to a steel beam erection support for a large-span truss structure. Background Art

[0002] During the construction of bridge steel beams, setting up temporary scaffolding for steel beam erection is the most common method of steel beam construction. In complex terrain or when there are existing roads that cannot be temporarily occupied, it is necessary to increase the span of the scaffolding to cross the complex terrain and use the scaffolding to increase the longitudinal spacing of the steel pipe piles. However, this will also lead to an increase in the span of the longitudinal distribution beam and a decrease in the bending resistance. It is necessary to increase the longitudinal distribution beam steel model or a self-made box-type structure to improve the strength and rigidity of the longitudinal distribution beam, resulting in a significant increase in the self-weight of the longitudinal distribution beam and the entire scaffolding. This will not only make it difficult to install and disassemble the scaffolding and affect the construction quality and progress, but will also increase construction costs and safety risks, and the lifting cost is also high. Summary of the invention

[0003] In view of this, the present invention aims to propose a large-span truss structure steel beam erection bracket to solve the problems of structural strength and weight balance when the span of the distribution beam in the existing steel beam erection temporary bracket is increased.

[0004] To achieve the above object, the technical solution of the present invention is achieved as follows:

[0005] A large-span truss structure steel beam erection bracket, comprising a steel pipe pile, a transverse connection component and a longitudinal connection component;

[0006] The steel pipe piles are evenly arranged in four rectangular shapes, and the two longitudinal steel pipe piles are connected by longitudinal connecting components, and the two transverse steel pipe piles are connected by transverse connecting components;

[0007] The longitudinal connection assembly comprises an upper longitudinal truss and a lower longitudinal truss, wherein the upper longitudinal truss is connected to the lower longitudinal truss by an oblique brace, wherein two oblique braces are provided at the left and right ends of the longitudinal connection assembly, and the two oblique braces are provided in an "eight"-shaped structure; both left and right ends of the upper longitudinal truss are provided with a protrusion that can cooperate with the top of the steel pipe pile, and the upper longitudinal trusses on the two longitudinal steel pipe piles are connected by a cross beam, and at least three cross beams are provided at intervals along the length direction of the upper longitudinal truss;

[0008] The transverse connection assembly includes an upper transverse truss and a lower transverse truss. The upper transverse truss is arranged corresponding to the upper longitudinal truss, and the lower transverse truss is arranged corresponding to the lower longitudinal truss.

[0009] Furthermore, the steel pipe pile is provided with a pile cap which cooperates with the raised portion.

[0010] Furthermore, the chords of the upper longitudinal truss, the lower longitudinal truss, the upper transverse truss and the lower transverse truss are all made of double H-shaped steel, and the vertical bars and the diagonal bars are all made of round steel tubes.

[0011] Furthermore, the oblique upward end of the oblique brace is arranged corresponding to the connection between the vertical rod and the oblique rod in the upper longitudinal truss, and the oblique downward end is arranged corresponding to the connection between the lower longitudinal truss and the steel pipe pile.

[0012] Furthermore, the crossbeam includes two H-shaped steels arranged at intervals, and the two H-shaped steels are connected by a connecting piece.

[0013] Furthermore, the connecting member is arranged corresponding to the raised portion on the upper longitudinal beam.

[0014] Furthermore, the connecting member is a rectangular parallelepiped structural member, and the connecting member extends between two flange plates of the H-shaped steel and is connected to the H-shaped steel.

[0015] Compared with the prior art, the large-span truss structure steel beam erection bracket described in the present invention has the following advantages:

[0016] The present invention provides a large-span truss structure steel beam erection bracket, which has the advantages of simple structure, easy construction, light weight, good applicability, and high structural stability.

The structural force is clear, the deformation is small, and it is more convenient for steel beam erection construction. All the truss rods are conventional materials and the cost is low. Compared with traditional large-span brackets, this erection bracket can support a larger span, use less materials, and each rod can be processed separately and welded on site. It is convenient and quick to hoist and install, which speeds up the construction progress and makes the construction safer. It can be applied to a variety of complex terrain environments.

[0022] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the present invention, rather than to limit the present invention. It should also be noted that, for ease of description, only parts related to the present invention, rather than all structures, are shown in the accompanying drawings.

[0023] A large span truss structure steel beam erection bracket, such as Figure 1 and Figure 2 As shown, it includes steel pipe piles 1, transverse connection components and longitudinal connection components. The steel pipe piles 1 are evenly arranged in four rectangular shapes, and the two longitudinal steel pipe piles 1 are connected by the longitudinal connection components, and the two transverse steel pipe piles 1 are connected by the transverse connection components.

[0024] The above-mentioned longitudinal connection assembly includes an upper longitudinal truss 2 and a lower longitudinal truss 3, and the upper longitudinal truss 2 and the lower longitudinal truss 3 are connected by a diagonal brace 4. Two diagonal braces 4 are arranged corresponding to the left and right ends of the longitudinal connection assembly, and the two diagonal braces 4 are arranged in an "eight" shape structure; the left and right ends of the upper longitudinal truss 2 are provided with a protrusion 5 that can cooperate with the top of the steel pipe pile 1, and the upper longitudinal trusses 2 on the two longitudinal steel pipe piles 1 are connected by a cross beam 6, and the cross beam 6 is arranged at least three times along the length direction of the upper longitudinal truss 2.

[0025] For example, the upper longitudinal truss 2 and the lower longitudinal truss 3 can be fixed to the steel pipe piles 1 by conventional means such as welding, and one end of the diagonal brace 4 can be welded and fixed to the upper longitudinal truss 2, and the other end can be welded and fixed to the lower longitudinal truss 3. By adopting two diagonal braces 4 arranged in an "eight" shape structure, the structural strength of the longitudinal connection assembly can be effectively improved, ensuring that the longitudinal connection assembly can stably connect the two longitudinal steel pipe piles 1.

[0026] In actual application, three, four or more cross beams 6 can be arranged at intervals, wherein two cross beams 6 are arranged corresponding to the two ends of the upper longitudinal truss 2 respectively, and the remaining cross beams 6 are arranged at intervals along the length direction of the upper longitudinal truss 2, and the front and rear ends of each cross beam 6 can be welded and fixed to the front and rear upper longitudinal trusses 2 respectively to achieve the connection and fixation of the front and rear upper longitudinal trusses 2, which is beneficial to improve the overall structural strength and stability of the erection bracket.

[0027] The above-mentioned transverse connection assembly includes an upper transverse truss 10 and a lower transverse truss 11, wherein the upper transverse truss 10 is arranged corresponding to the upper longitudinal truss 2, and the lower transverse truss 11 is arranged corresponding to the lower longitudinal truss 3. Exemplarily, the upper transverse truss 10 and the lower transverse truss 11 can also be fixedly connected to the steel pipe pile 1 by conventional means such as welding. By arranging the upper transverse truss 10 corresponding to the upper longitudinal truss 2 and arranging the lower transverse truss 11 corresponding to the lower longitudinal truss 3, a stable reinforcement structure can be formed on the erection bracket without significantly increasing the weight of the erection bracket.

[0028] Preferably, the steel pipe pile 1 is provided with a pile cap 7 that cooperates with the raised portion 5. Exemplarily, the pile cap 7 is fixed on the steel pipe pile 1, and a plurality of reinforcing plates are fixed around the pile cap 7 to improve the structural strength of the pile cap 7. The provision of the pile cap 7 can improve the structural strength and support area of ​​the top of the steel pipe pile 1, ensuring that the steel pipe pile 1 can be more stably connected to the raised portion 5 on the upper longitudinal truss 2. In addition, the crossbeam 6 can also be provided corresponding to the pile cap 7, so that the longitudinal connection assembly can form a composite structural reinforcement structure at the end of the steel pipe pile 1, so as to improve the structural strength and anti-deformation performance of the end of the steel pipe pile 1.

[0029] Preferably, the chord members of the upper longitudinal truss 2, the lower longitudinal truss 3, the upper transverse truss 10, and the lower transverse truss 11 are all made of double H-shaped steel 8, and the vertical and diagonal rods are all made of round steel tubes. By using double H-shaped steel 8 as the chord member and round steel tubes as the vertical and diagonal rods, the structural weight of the longitudinal connection assembly and the transverse connection assembly can be controlled while ensuring the structural strength.

[0030] Preferably, the obliquely upward end of the diagonal brace 4 is arranged corresponding to the connection between the vertical rod and the diagonal rod in the upper longitudinal truss 2, and the obliquely downward end is arranged corresponding to the connection between the lower longitudinal truss 3 and the steel pipe pile 1. By adopting the above arrangement, a stable trapezoidal structure can be formed between the diagonal brace 4 and the upper longitudinal truss 2 and the lower longitudinal truss 3, and when a long longitudinal connection component is adopted, it can still have high structural strength and stability.

[0031] Preferably, the cross beam 6 includes two H-shaped steels 8 arranged at intervals, and the two H-shaped steels 8 are connected by a connector 9. Exemplarily, the connector 9 is arranged corresponding to the protrusion 5 on the upper longitudinal beam, and the connector 9 can be fixed to the H-shaped steel 8 by conventional means such as welding.

[0032] In actual application, the connector 9 is a rectangular parallelepiped structural member, and the connector 9 extends between the two flange plates of the H-shaped steel 8 and is connected to the H-shaped steel 8. By adopting the connector 9 of the rectangular parallelepiped structural member, the connector 9 itself has high structural strength and stability, and can form a crossbeam 6 with a large supporting area in conjunction with two H-shaped steels 8, and the weight of such a crossbeam 6 is also relatively light. By arranging a plurality of connectors 9 at intervals along the length direction of the crossbeam 6 and arranging the connector 9 at the raised portion 5, not only the structural strength of the crossbeam 6 can be further improved, but also the structural strength of the connection between the crossbeam 6 and the upper longitudinal truss 2 can be improved.

[0033] This type of erection bracket is mainly composed of a crossbeam 6, a truss structure, a steel pipe pile 1, a diagonal brace, and a connection system. The four steel pipe piles 1 of the bracket are connected by a longitudinal connection assembly and a transverse connection assembly, wherein the chord of the upper longitudinal truss 2 is made of double H-shaped steel 8 and is set on the top of the steel pipe pile 1, and is welded to the pile cap 7 of the steel pipe pile 1 as a whole, and the lower chord is connected to the pile body of the steel pipe pile 1. The vertical bars and diagonal bars of each truss structure are round steel pipes, connecting the upper and lower chords, and the middle of the two trusses is connected by a connection system. At the same time, a diagonal brace 4 (such as a steel pipe) is set below the upper longitudinal truss 2, and the lower part of the diagonal brace 4 is connected to the lower longitudinal truss 3. By making the diagonal brace 4 and the diagonal bars on the longitudinal truss in the same direction, the load is transferred to the diagonal brace 4 through the diagonal bar, and then transferred to the steel pipe pile 1 through the diagonal brace 4, and the horizontal load is jointly borne by the longitudinal connection assembly and the transverse connection assembly. In addition, the force transmission joint can also be welded and fixed with a stiffening plate for local reinforcement as needed.

[0034] The present invention provides a large-span truss structure steel beam erection bracket, which has the advantages of simple structure, easy construction, light weight, good applicability, and high structural stability. By adopting a truss structure to replace the longitudinal distribution beam of the traditional bracket, it is not only an upper load-bearing structure, but also plays the role of a longitudinal connection system. The structural force is clear, the deformation is small, and it is more convenient for steel beam erection construction. All the truss rods are conventional materials and the cost is low. Compared with traditional large-span brackets, this erection bracket can support a larger span, use less materials, and each rod can be processed separately and welded on site. It is convenient and quick to hoist and install, which speeds up the construction progress and makes the construction safer. It can be applied to a variety of complex terrain environments.
