The specific embodiment
Embodiment 1
As depicted in figs. 1 and 2, a kind of multi-functional bar location skeleton, which comprises at least some main trusses 1, steel corbel 4 and positioning support 6.
Main truss 1 is the Rhombic Truss that is mutually permanently connected and is formed by horizontal-associate 101, column 102 and diagonal brace 103, and the position that station is corresponding is installed with steel anchor beam in Sarasota in the bottom of Rhombic Truss, is fixedly installed locating rectangle steel plate 104.
Main truss 1 is machined directly to whole single-unit structure by factory, before the construction of steel anchor beam, by tower crane, is lifted above Sarasota, in use carries out cement pouring construction with reinforcing bar, and every joint main truss 1 can be increased formation multi-section structure by welding.
On every joint main truss 1, there is a 10t Chain block 3.
Positioning support 6 be fixed on steel anchor beam in Sarasota install station under, on positioning support 6, be provided with positioning bolt 601, positioning bolt 601 is for finely tuning the position of steel anchor beam 2, makes steel anchor beam 2 accurate location in installation process.
Positioning support 6 can be pulled down when carrying out cement pouring construction, and in the construction of follow-up steel anchor beam 2, continues to use.
Steel corbel 4 is fixedly connected with steel anchor beam 2 by steel corbel pre-embedded steel slab 401, and steel corbel pre-embedded steel slab 401 arranged outside have fixing steel plate 403, and the outer side-lower of steel corbel 4 has interim otic placode 402, and interim otic placode 402 is connected with 5t Chain block 5.
Fixing steel plate 403 is corresponding with locating rectangle steel plate 104, and can be mutually permanently connected.
Steel anchor beam 2 is by lifting directly over positioning support 6, and the cooperation by 5t Chain block 5 makes slowly landing stably of steel anchor beam 2, and with 6 laminatings of positioning support, the fixing steel plate 403 of steel corbel 4 and the locating rectangle steel plate of main truss 1 104 are fixing simultaneously; Steel anchor beam 2 is connected with each 10t Chain block 3 after falling surely.
Steel anchor beam 2 fall steady after, by coordinating of positioning bolt 601 and 10t Chain block 3, can realize the fine setting of steel anchor beam 2 positions, meet the accurate location of steel anchor beam installation.
After steel anchor beam 2 has been located, do not remove the reinforcing bar template concrete engineering construction that main truss 1 directly carries out king-post.After concrete strength meets the demands, removal positioning support 6, measures examination to steel anchor beam, the installation of single steel anchor beam 2.
Embodiment 2
The structure of the present embodiment and embodiment 1 is basic identical, and different is the location that Sarasota needs a plurality of steel anchor beams 2 in construction.
Main truss 1 adopts more piece form, and the construction station of the corresponding steel anchor beam 2 of length of every joint, first saves steel anchor beam 2 to head according to the structure in embodiment 1 and install, and concrete installation is as follows:
As shown in Figure 3, positioning support 6 is fixed under the station of first joint steel anchor beam 2, then head is saved to the bottom of main truss 1 and the built-in fitting in Sarasota and be welded and fixed, first joint main truss 1 has 4, is divided into two bond pads in the left and right sides of the upper joint king-post of Sarasota.
As shown in Figure 4, by head save steel anchor beam 2 by lifting directly over positioning support 6, the cooperation by 5t Chain block 5 makes slowly landing stably of steel anchor beam 2, and with 6 laminatings of positioning support.
As shown in Figure 5, after first joint steel anchor beam 2 falls surely on positioning support, the fixing steel plate 403 of steel corbel 4 is fixing with the locating rectangle steel plate of main truss 1 104; Steel anchor beam 2 is connected with each 10t Chain block 3 after falling surely.
Then by 10t Chain block 3, coordinate 601 pairs of first joint steel anchor beams 2 of positioning bolt to finely tune, make first joint steel anchor beam 2 be adjusted to the position of construction requirement completely, realize accurately location.
First joint steel anchor beam 2 is not removed the reinforcing bar template concrete engineering construction that first joint main truss 1 directly carries out king-post after having located.
After concrete strength meets the demands, removal positioning support 6, saves steel anchor beam 2 to head and measures examination, the installation of first joint steel anchor beam 2, and prepare to carry out follow-up construction.
As shown in Figure 6, by the main truss of follow-up sections 1 and 1 welding of head joint main truss are realized to building of more piece main truss 1, then positioning support 6 is arranged on to the station below of follow-up sections steel anchor beam 2, and repeats steel anchor beam 2 installations that above-mentioned steps completes follow-up sections.
The parts that the present embodiment does not describe in detail and structure belong to well-known components and common structure or the conventional means of the industry, here not narration one by one.
