Description

Technical Field

[0001] This utility model relates to the technical field of road cover beam construction, and in particular to a cover beam support. Background Technology

[0002] Currently, the main support system for large cantilever girder structures is a multi-column continuous beam system. This means that the girder support system needs to be laid on the ground with a full-span support frame. The full-span support frame requires steel pipe support columns of different heights to be set on both sides of the girder. The steel pipe support columns extend along the bottom of the girder to the ground. This causes several steel pipe support columns to interfere with the ground road below the girder. Vehicles must avoid the support columns, which affects the lane layout of the ground road below the girder and increases the traffic pressure on the ground. Utility Model Content

[0003] In view of the shortcomings and defects of the existing technology, a cover beam support is provided. In order to achieve the purpose of erecting the support under the existing traffic conditions, the present invention provides the following technical solution.

[0004] A cap beam support includes a cap beam, a pier, a support platform, and a support column assembly. The pier is fixedly installed between the cap beam and the support platform. The support platform is fixedly installed underground. Connecting brackets are erected on both sides of the pier. A fall arrestor platform is fixedly connected to the lower end of the connecting brackets. The support column assembly is located at the lower end of the connecting brackets. The support column assembly includes a first support column symmetrically arranged on both sides away from the pier and a second support column arranged at both ends. The lower end of the first support column is fixed to the ground, and the lower end of the second support column is fixedly connected to the upper surface of the support platform. A passage space is formed between the first support column and the second support column.

[0005] Compared with the prior art, in this utility model, the lower end of the connecting bracket is provided with a first support column and a second support column, which ensures the stability of the connecting bracket installation. A passage space is formed between the first support column and the second support column to ensure that vehicle traffic is not affected during construction. Furthermore, an anti-fall platform is fixedly connected to the lower end of the connecting bracket to prevent small objects from falling from a height and injuring people, while also preventing mud and curing water from seeping in and affecting the downward movement of vehicles.

[0006] Furthermore, the connecting bracket includes several upper chords, lower chords, and a Bailey beam disposed between the upper chords and the lower chords. The upper chords are evenly arranged at the end of the Bailey beam away from the support platform, and the lower chords are correspondingly disposed with the support column assembly.

[0007] With the above improvements, the connecting bracket includes an upper chord and a lower chord, and a Bailey beam is set between the upper chord and the lower chord. The Bailey beam can meet different needs by adjusting the number and connection method of the truss units. At the same time, the Bailey beam structure is stable, has high load-bearing capacity, and is easy to install. The upper chord and the lower chord can prevent the Bailey beam from being worn due to long-term direct contact.

[0008] Furthermore, the fall arrest platform includes connecting steel, square wooden planks, and enclosed sheet metal. Several connecting columns are provided on the fall arrest platform. An I-beam extension is provided at the lower end of the Bailey beam. The upper end of the connecting rod is snapped between the flanges of the I-beam extension and fixedly connected by a first tie rod. Double-jointed steel connectors are provided at the lower end of the connecting steel and on the Bailey beam. A second tie rod is provided between the double-jointed steel connectors and passes through the fall arrest platform and the double-jointed steel connectors.

[0009] Through the above improvements, the fall arrest platform includes connecting steel, square wooden planks, and enclosed iron sheets. The three-layer design of the fall arrest platform enhances its strength. The fall arrest platform is fixedly installed at the lower end of the Bailey bridge beam, which has an I-beam extension. Several connecting rods are installed on the fall arrest platform, with the upper ends of the connecting rods engaging with the flanges of the I-beam extension and fixedly connected by a first tie rod. This ensures that the connecting rods are well secured to the I-beam extension at the lower end of the Bailey bridge beam. Double-jointed steel connectors are installed at the lower end of the connecting steel and on the Bailey bridge beam. A second tie rod is installed between the double-jointed steel connectors, penetrating both the fall arrest platform and the double-jointed steel connectors. This securely connects the fall arrest platform to the lower end of the Bailey bridge beam and improves the stability of the connection.

[0010] Furthermore, a sand box is provided at one end of the support column assembly near the lower chord. The sand box includes an upper box and a lower box. The upper end face of the upper box abuts against the lower end face of the lower chord, and the lower end face of the lower box abuts against the upper end face of the support column assembly. The upper box is filled with C30 concrete, and the lower box is filled with fine sand.

[0011] Through the above improvements, a sand box is set at the lower end of the support column assembly. The sand box includes an upper box and a lower box. The upper box is filled with C30 concrete, and the lower box is filled with fine sand to ensure compaction. During use, the height of the connecting bracket can be easily adjusted, reducing the operation of construction personnel.

[0012] Furthermore, a diagonal bracing truss is installed between the cap beam and the connecting bracket. The upper inclined surface of the diagonal bracing truss abuts against the cap beam, and the lower end is fitted onto the upper end of the upper chord. A protective fence is provided at the upper plane of the diagonal bracing truss.

[0013] Through the above improvements, a diagonal bracing truss is installed between the cap beam and the connecting support. The upper inclined surface of the diagonal bracing truss abuts against the cap beam, which makes the cap beam less prone to deformation after pouring. At the same time, it can improve the stability of the support during construction and enhance safety. Furthermore, a protective railing is installed at the upper plane of the diagonal bracing truss, which can further improve safety and prevent construction workers from falling accidentally.

[0014] Furthermore, a first fixing frame is installed between the first support columns on the same side. The first fixing frame includes a first horizontal bar, a second horizontal bar, a first diagonal bar, and a second diagonal bar. The first horizontal bar and the second horizontal bar are horizontally arranged, and the first diagonal bar and the second diagonal bar are intersected. A second fixing frame is installed between the second support columns on the opposite side. The second fixing frame includes a third horizontal bar, a fourth horizontal bar, a third diagonal bar, and a fourth diagonal bar. The third horizontal bar and the fourth horizontal bar are horizontally arranged, and the third diagonal bar and the fourth diagonal bar are intersected.

[0015] Through the above improvements, a first fixing frame is installed between the two first support columns on the same side, and a second fixing frame is set between the two second support columns on the opposite side. The first fixing frame and the second fixing frame can improve the stability of the connection between the first support column and the second support column, making the whole support less likely to collapse.

[0016] Furthermore, an expansion bolt is installed between the first support column and the support platform.

[0017] By installing expansion bolts between the first support column and the support platform, the stability of the connection can be further improved through the above improvements. Attached Figure Description
