Embodiment Construction
[0029] The invention will be further described below with specific examples:
[0030] refer to Figure 1 to Figure 5 , the elevation difference node construction process of steel truss floor deck construction, the steel truss floor deck adopted includes steel bar truss 31 and galvanized plate 30 connected to its bottom, including the following construction steps.
[0031] 1) Prepare Z-shaped backing plate and additional steel bars for nodes
[0032] According to the height difference H of the designed floor, a Z-shaped backing plate 2 is made in advance with a steel plate with a thickness of 5 mm. The Z-shaped backing plate 2 includes a vertical plate 20, and the two sides of the vertical plate 20 are vertically connected to the upper wing 21 and the lower wing 22 respectively. The width of the upper wing is 50mm, and the width of the lower wing is 60mm. The width of the riser 20 is equal to the height difference H of the design floor at the node; the additional reinforcement...

The invention relates to the technical field of construction, and provides an elevation difference joint construction technology for steel bar truss floor deck construction. The elevation difference joint construction technology for steel bar truss floor deck construction comprises the steps of (1) preparing a Z-shaped bearing plate and joint additional bars; (2) installing the Z-shaped bearing plate and a side formwork, wherein the length of the portion, erected on a steel beam, of an upper portion of the Z-shaped bearing plate is at least 50mm; (3) installing a floor deck; (4) arranging the joint additional bars, wherein the two ends of each joint additional bar are welded to a steel bar truss of a high-elevation floor deck at the position of a change of the floor slab elevation and a steel bar truss of a low-elevation floor deck at the position of the change of the floor slab elevation respectively, and the middle section of each joint additional bar is arranged on a joint; (5) carrying out stud welding; (6) carrying out acceptance on a formwork installation project ; (7) carrying out concrete pouring. The elevation difference joint construction technology for steel bar truss floor deck construction has the remarkable and substantive advantages that due to the fact that the Z-shaped bearing plate and the additional bars are arranged at the position of the change of floor slab elevation, joint connection between elevation difference joints in the process of construction of the floor decks is achieved, construction quality of the high-and-low elevation difference joints of the floor decks is improved, the working procedure of construction is simplified, and the construction period is shortened.
Description
technical field [0001] The invention relates to the technical field of building construction, in particular to the construction technology of reinforced truss floor decks. Background technique [0002] Reinforced truss floor deck is a new building composite material highly recommended by the construction industry today. It has the advantages of light weight, high strength, factory production, convenient installation, beautiful and durable, etc. It is an advanced building decoration material integrating construction and decoration. [0003] In the field of design and construction of steel structure floor slabs, the National Standards Committee promulgated the national standard "Reinforced Truss Floor Slabs" on February 09, 2012, and it will be implemented on August 1, 2012. This standard specifies the terms and definitions, marks and examples, materials, requirements, test methods, inspection rules, ordering content, signs, packaging, transportation and storage of reinforced ...
