Embodiment 1

[0029] Such as figure 1 As shown, a steel-concrete composite beam concrete bridge deck construction support includes a support column 1, a support beam 2, a boom 3, a bottom form 4 and a construction channel 5, and the number of the support column 1 and the suspension rod 3 is multiple. The support beam 2 is arranged horizontally, and the lower part of the support beam 2 is vertically connected to multiple support columns 1 at intervals, and the bottom of the multiple support columns 1 is horizontally connected to the base form 4, and the support beam 2 and the base form 4 are connected by multiple suspension rods 3 , The bottom formwork 4 is connected to the construction channel 5 below.

[0030] A construction method of a steel-concrete composite beam concrete bridge deck construction support, comprising the following steps:

[0031] 1) Install the steel-concrete composite beam concrete bridge deck construction support, connect the support column 1 to the top surface of the...

Embodiment 2

[0038] Such as figure 2 As shown, on the basis of Embodiment 1, it also includes the upper bracket flat connection 6, the bracket diagonal brace 7 and the lower bracket flat connection 8, and the upper bracket flat connection 6 is sequentially passed between two adjacent bracket columns 1 from top to bottom. 1. The support diagonal brace 7 is connected with the lower support parallel connection 8, the upper support support parallel connection 6 and the lower support support parallel connection 8 are arranged horizontally, the upper end of the support support diagonal brace 7 is connected to the support column 1 at the left end of the upper support support parallel connection 6, and the support diagonal The lower end of support 7 is connected to the support column 1 at the right end of the lower support flat joint 8.

[0039] The bracket parallel 6 is welded with the bracket column 1 to prevent the bracket column 1 from toppling over; the bracket diagonal brace 7 is welded to ...

Embodiment 3

[0041] On the basis of Example 2, the suspender 3 is made of fine-rolled rebar, and both ends of the suspender 3 are provided with connecting nuts and gaskets. The steel bars of fine-rolled rebar can be screwed with internal threaded connectors at any cross-section for connection or screwed with threaded nuts for anchoring. It has good adaptability and high strength. Nuts and gaskets can adjust the height of the bottom mold , to ensure construction accuracy.

[0042] Described suspender 3 adopts steel bar or steel pipe, and both ends of steel bar or steel pipe are all provided with screw thread. There are threads at both ends, which is convenient for adjusting the height of the bottom mold, and the operation is simple and convenient.

Abstract

The invention belongs to the technical field of construction of steel-concrete composite beam concrete bridge decks, and concretely relates to a steel-concrete composite beam concrete bridge deck construction support and a construction method thereof. The support comprises support stand columns, a support cross beam, hanging rods, a bottom die and a construction channel. The number of the supportstand columns and the number of the hanging rods are multiple. The support cross beam is horizontally arranged, and the support stand columns are vertically connected below the support cross beam at intervals, the bottom die is horizontally connected below the plurality of support stand columns, the support cross beam is connected with the bottom die through the hanging rods, and the constructionchannel is connected to the lower portion of the bottom die. A main bearing structure of a bridge deck slab of a support method in existing bridge deck construction is supported below the bridge deckslab, the whole support is of a pressed structure and is large in weight, the support is usually welded to or bolted to a steel plate beam, coating of the steel plate beam is damaged, the support is arranged above the bridge deck slab and mainly of a tension structure, the overall weight is small, the welding position of the support and the steel plate beam is located on the non-coating portion ofthe top face of the steel plate beam, and coating is effectively protected.

Description

technical field [0001] The invention belongs to the technical field of steel-concrete composite beam concrete bridge decks, and in particular relates to a steel-concrete composite beam concrete bridge deck construction support and a construction method thereof. Background technique [0002] As an important part of the bridge structure, the bridge deck installation in the steel-concrete composite beam has an important influence on the traffic capacity of the road. With the development of bridge construction in our country, the research on bridge deck installation technology has gradually been paid attention to, and extensive and in-depth research has been carried out gradually. [0003] Steel plate composite girder bridges, especially steel girder bridges in which steel girders are composed of multiple I-shaped main girders and cross girders. Multiple main girders are arranged vertically at intervals. The top surface of the main girder is used more and more because of its si...
