Description

Technical Field

[0001] The utility model relates to the technical field of bridge construction, specifically to the technical field of a pylon construction support. Background Technique

[0002] In bridge construction, especially in the construction of cable-stayed bridges and suspension bridges, the pylon is a key basic structure. Generally, the pylon is relatively high, which is convenient for supporting the main cable or stay cables, and thus structural components such as cross beams and main girders need to be installed at the top or side of the pylon.

[0003] When constructing these cross beams and main girders, due to the high height of the pylon and the relatively far distance from the ground, it is very difficult to build a support. In this regard, for example, Chinese Patent CN206859068U, an assembled support structure for the lower cross beam of a cable-stayed bridge pylon, discloses a solution of a triangular truss fixed to the tower legs of the two side pylons through lower fulcrums. However, this solution also has problems such as difficult positioning, especially the problem of increased construction difficulty in the balance of both ends of the cross beam. Content of the Utility Model

[0004] In summary, aiming at the deficiencies of the prior art, the utility model provides a pylon construction support, aiming to improve construction efficiency and safety, and at the same time reduce construction costs.

[0005] To achieve the above object, the utility model adopts the following technical solutions:

[0006] A pylon construction support includes a first truss horizontally and transversely pre-embedded and fixed in the tower column, a second truss intersecting with the first truss and obliquely and transversely pre-embedded and fixed in the tower column, a diagonal rod arranged between the first truss and the second truss, and a first suspension rod with one end arranged on the tower column and the other end connected to the second truss;

[0007] It further includes a load-bearing beam arranged at the bottom of the second truss, and a bottom plate suspension rod connecting the load-bearing beam and the first truss.

[0008] Compared with the prior art, in this case, the first truss and the second truss are connected and pre-embedded and fixed in the tower column, and the lower second truss is lifted by the truss suspension rod, so that they act synchronously on the first truss to provide support. At the same time, a load-bearing beam is arranged at the bottom of the second truss, and the first truss and the load-bearing beam are connected by the bottom plate suspension rod, so that the load-bearing beam can be supported by both the first truss and the second truss, which reduces construction costs and difficulties while improving construction safety.

[0009] In a preferred embodiment, a distribution beam is arranged between the second truss and the load-bearing beam.

[0010] In some embodiments, the first suspension rods are plural and evenly distributed on the end face of the second truss.

[0011] In a preferred embodiment, the angle between the first suspension rod and the second truss is 60° to 90°.

[0012] In a preferred embodiment, the angle between the first hanger and the second truss is 90°. At this time, the angle between the first truss and the second truss is the same as the angle between the first hanger and the tower column, so that the force between the trusses is more stable.

[0013] In some embodiments, it also includes a third truss and a fourth truss pre-embedded and fixed on the beam cast by the construction bracket as described above, a diagonal rod arranged between the third truss and the fourth truss, and a second hanger having one end arranged on the tower column and connected to the fourth truss at one end.

[0014] In a preferred embodiment, the third truss and the fourth truss are trusses parallel to each other.

[0015] In some preferred embodiments, a distribution beam is provided at the upper end of the third truss. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The following examples further illustrate the features of the present invention and other related features to facilitate understanding by those skilled in the art:

[0023] Embodiment 1.

[0024] Please refer to Figures 1 to 3, A pylon construction support in this case includes a first truss 100 horizontally and transversely embedded and fixed in the tower column 1, a second truss 200 intersecting with the first truss and obliquely and transversely embedded and fixed in the tower column 1, and a diagonal rod 10 arranged between the first truss 100 and the second truss 200. That is, the second truss 200 is obliquely embedded at the lower part of the horizontally transverse first truss 100 at intervals, and it is connected to the first truss 100 on the outside, and at this time, the second truss 200 is at the lower end of the first truss 100 at the connection.

[0025] At this time, a first suspender 300 arranged at the other end of the tower column 1 and connected to the second truss 200 is used to lift the lower second truss 200, so that it acts on the first truss 100 synchronously to provide support.

[0026] In a preferred embodiment, the first suspenders 300 are plural and are evenly distributed on the outer end face of the second truss 200, that is, the end face away from the tower column 1. The specific quantity can be determined according to the truss. In this illustrated embodiment, 6 first suspenders 300 are evenly arranged.

[0027] Different from the traditional truss suspenders, the first suspenders 300 in this case provide direct support for the obliquely arranged second truss 200, so the included angle between the first suspenders 300 and the second truss 200 of 60° to 90° enables it to take into account both stability and construction convenience.

[0028] Furthermore, 90° can be adopted. At this time, the included angle between the first truss 100 and the second truss 200 is the same as the included angle between the first suspenders 300 and the tower column 1, making the force between the trusses more stable.

[0029] Further, it further includes a load-bearing beam 400 arranged at the bottom of the second truss 200. The load-bearing beam 400 and the first truss 100 are connected by a bottom plate suspender 500. At this time, as the topmost support structure, the structure composed of the first truss 100 and the second truss 200 is used to support the formwork system and the loads during construction. For the formwork system and pouring in the bridge construction field, it is a conventional technical means and will not be described in detail in this case. That is, in addition to the second truss 200 directly bearing the weight, the force can also be transmitted to the first truss 100 through the load-bearing beam 400, thus forming a uniformly stressed structure with interlocking links, which reduces the construction cost and difficulty while improving the construction safety.

[0030] More preferably, a distribution beam 20 is arranged between the second truss 200 and the load-bearing beam 400. The distribution beam 20 is located under the truss and is used to disperse the loads from the truss.

[0031] Embodiment Two.

[0032] In actual application, the cross beam 2 will be cast on the basis of the construction support as described above, and then the main beam 3 will be cast on the cross beam 2 to meet the requirements of hanging basket assembly and anchoring. At this time, the construction support of this case can also continue the method of embedding trusses as described above.

[0033] Please refer to Figures 4 to 6 , and also includes a third truss 600 and a fourth truss 700 pre-embedded and fixed on the beam 2 cast by the construction bracket as described above, and an inclined rod 10 arranged between the third truss and the fourth truss. The inclined rod 10 is also mentioned in the embodiment here. It is a measure to improve the stability during the truss construction and will not be specifically subdivided.

[0034] At this time, since the cross beam 2 bears the main vertical force, and the third truss 600 and the fourth truss 700 mainly play an auxiliary role on the outside, they can be parallel to each other.

[0035] Furthermore, the fourth truss 700 is suspended by a second suspension rod 800 disposed at the other end of the tower column 1 and connected to the fourth truss 700, so that it acts synchronously on the third truss 600 to provide support. Specifically, the arrangement and angle of the second suspension rod 800 are equivalent to those of the first suspension rod 300, and will not be repeated here.

[0036] Furthermore, a distribution beam 20 is provided at the upper end of the third truss 600. The distribution beam 20 is also mentioned in the first embodiment and is mainly used to distribute the load. This case does not make any specific subdivision or limitation on this.

[0037] As mentioned above, this case protects a type of cable tower construction support, and all technical solutions that are the same or similar to this case should be deemed to fall within the scope of protection of this case.
