Problems solved by technology

At present, in the construction process of reinforced truss floor decks, the spans that can be realized are small without temporary supports. waste
In order to meet the requirements of the floor slab with a large span, it is necessary to set up temporary supports at the lower part of the floor slab. The traditional way of adding temporary supports to the lower part of the floor slab is a large amount of work and takes a long time to install and dismantle.

Embodiment 1

[0045] Embodiment one sees Figure 1-6 As shown, a temporary support structure for the upper part of a reinforced truss floor deck includes a reinforced truss floor deck, a structural beam 1, a temporary support composite frame and a temporary support. The reinforced truss floor deck includes a bottom supporting plate 2 and A group of floor deck steel bars 3 arranged along the longitudinal length of the bottom supporting plate 2 and arranged at intervals along the transverse direction.

[0046] The bottoms at both ends of the reinforced truss floor deck are respectively lapped on the structural beams 1 on both sides, and the temporary supports are arranged in two rows at intervals along the length direction of the structural beams 1, and the two rows of temporary supports are arranged in pairs and respectively Placed and fixedly connected on the upper side of the structural beams 1 on both sides, the temporary supporting composite frame is located above the steel truss floor d...

Embodiment 2

[0058] Example 2 Participation Figure 7 As shown, when the span of the floor deck is large, the temporary support can be a combination of a temporary support mother frame 4 and two temporary support sub-frames 5, wherein the temporary support mother frame is located in the middle, and the temporary support sub-frames are located on both sides. The way of connection is the same as that of Embodiment 1.

Embodiment 3

[0059] Example 3 Participation Figure 8 As shown, the difference from the first embodiment is that when the form of the steel truss is different, the temporary support of the steel truss floor deck of the present invention can still be used, and the support method is the same as the above-mentioned method.

Abstract

The invention relates to a steel bar truss floor support plate upper part temporary support structure and a construction method thereof, the steel bar truss floor support plate upper part temporary support structure comprises a steel bar truss floor support plate, a structural beam, temporary support combination frames and a temporary support, the steel bar truss floor support plate comprises a bottom support plate and floor support plate steel bars, and each temporary support combination frame comprises at least one temporary support mother frame and a temporary support son frame; the temporary supporting mother frames and the temporary supporting child frames are alternately arranged and matched with each other, the connecting ends of the temporary supporting child frames are inserted into and overlapped with the connecting ends of the temporary supporting mother frames, the temporary supporting mother frames and the temporary supporting child frames are connected into a whole through connecting assemblies, and hanging pieces in one-to-one correspondence are arranged between the temporary supporting combination frames and floor support plate steel bars. The temporary support can be modularly manufactured, does not need to be customized, is arranged on the upper portion of the floor support plate, construction is easy, the work amount is small, the construction speed of the temporary support can be greatly increased, any adjustable span can be achieved within the allowable range of the bearing capacity, and use is convenient.

Description

technical field [0001] The invention belongs to the field of civil engineering building structures, in particular to a temporary support structure for the upper part of a reinforced truss floor deck and a construction method thereof. Background technique [0002] Reinforced truss floor decks are currently widely used in various industrial and civil building floors. Reinforced truss floor decks use steel bars as the upper and lower chords to form steel bar trusses, and are formed by spot welding of steel bar trusses and bottom plates, which can realize mechanized production and effectively reduce The amount of on-site steel bar binding, improving the speed of on-site construction, and matching the construction period and structural structure of steel structures are indispensable components in the current process of building industrialization. [0003] The reinforced truss floor-slab composite floor slab uses the floor slab as a template in the construction process, which can ...
