Example

[0040] First embodiment:

[0041] Please refer to Figure 1 to Figure 4 , this embodiment provides a construction platform for aerial work, which includes a transverse steel plate 1, at least two partition steel plates 2 and at least one bracket 3; Between the box beams 4, the two sides of the transverse steel plate 1 in the width direction are respectively used for welding the cover plates of the two box beams 4; The lower side of the steel plate 1, and any partition steel plate 2 extends along the width direction of the transverse steel plate 1; a bracket 3 is arranged between any two adjacent partition steel plates 2, and the bracket 3 is connected to the transverse steel plate 1 Oppositely arranged; the baffle steel plate 2 , the bracket 3 and the cross-connected steel plate 1 are used to form a rectangular tube with open ends; the horizontal-connected steel plate 1 is provided with a manhole 5 between any two adjacent baffle steel plates 2 . Preferably, the manhole 5 is...

Example

[0047] Second embodiment:

[0048] Please refer to Figure 1 to Figure 3 and Figure 5 , this embodiment provides an aerial work construction platform, which is substantially the same as the aerial work construction platform of the first embodiment, the difference between the two is that in the aerial work construction platform of this embodiment, the support plate 32 includes a plurality of strips A plurality of strip-shaped straight plates 321 are arranged side by side.

[0049] Please refer to Figure 5 , a side surface of the strip-shaped straight plate 321 away from the cross bar 31 is provided with an anti-skid pattern 322 .

[0050] In the above-mentioned embodiment, 1. The support plate 32 is designed as a structure in which a plurality of strip-shaped straight plates 321 are assembled side by side, which is also beneficial to put the support plate 32 into and out of the manhole 5 in parts. 2. Due to the high-altitude operation, the anti-skid texture 322 can increa...

[0051] Third embodiment:

[0052] The present embodiment provides a method for constructing a 4-bridge box girder using the above-mentioned aerial work construction platform, comprising the following steps:

[0053] Step 1: Weld a transverse steel plate 1 between any two adjacent box beams 4;

[0054] Step 2: The construction personnel enter above the bracket 3 through the manhole 5, and weld and fix any two adjacent box beams 4 through the partition steel plate 2.

[0055] The method for building 4 box girder bridges in the present embodiment: using the above-mentioned aerial work construction platform to construct 4 box girder bridges can provide a stable and easy-to-build construction platform without affecting the normal traffic under the bridge. Improve the efficiency of bridge construction.

[0056] Further, after the above step 1, the bracket 3 is placed under the transverse steel plate 1 through the manhole 5, and the bracket 3 is installed between the two partition ...

Abstract

The invention discloses an aloft construction platform, and relates to the technical field of building construction. The aloft construction platform comprises transversely-connected steel plates, at least two partition steel plates and at least one bracket. The transverse-connected steel plates are each in a long strip shape. The partition steel plates are sequentially arranged on the lower side faces of the transversely-connected steel plates in the length direction of the transversely-connected steel plates. Each partition steel plate extends in the width direction of the transversely-connected steel plates. Each bracket is arranged between any two adjacent partition steel plates. The brackets are opposite to the transversely-connected steel plates. A manhole is formed in the position, between any two adjacent partition steel plates, of each transversely-connected steel plate. According to the aloft construction platform, the rigid hanging is formed through the brackets erected between every two adjacent partition steel plates, and the effect of being high in platform stability without affecting the traffic below the platform is realized on the aloft operation platform. On the basis, the invention further provides a box girder bridge constructing method.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to an aerial work construction platform and a method for building a box girder bridge. Background technique [0002] There are generally three types of existing bridge aerial work construction platforms, which are scaffolding platforms, hanging basket platforms and elevator platforms. [0003] The technical scheme of the scaffolding platform is: use steel pipes and fasteners, the fasteners include pan buckles or bowl buckles, use fasteners to connect the steel pipes horizontally and vertically to form a frame, and erect them on the top after reaching the required construction height platform. Its disadvantages are that there are many materials, it takes up a lot of space, it affects the traffic under the platform, and it takes a long time to build. [0004] The technical solution of the hanging basket platform is to make a hanging basket that can meet the constructio...
