Description
Technical field
A kind of large span assembled open-type building bottom plate I-beam erection support and mounting assembly are the utility model is related to,
Belong to construction engineering technical field.
Background technology
I-beam refers to that section is I-shaped rolled iron beam or girder steel, is that truss is widely used as in building field
System or high-rise floor beam, such as main purlin or secondary purlin Important building component.For the less building bottom plate of span, such as roof boarding,
Floor support plate building system, I-beam can bear to build the pressure of bottom plate well.But when building bottom plate span increase or
When hoisted load increases, the pressure that I-beam is born also increases therewith, in I-beam top flange upper surface and building contacts baseplate
The problem of understrressing occurs in part.
For the problem, prior art is usually using Π shapes or the fixed seat of Ω shapes on the top of building bottom plate or bottom
Reinforcing equivalent process (Fig. 2 that such as number of patent application is 200720007804.X) is carried out to building bottom plate, or passes through welding
The part such as support frame or pad increases the Area of bearing of I-beam top flange upper surface.Wherein, by way of installing fixed seat additional
Although good invigoration effect can be played, due to needing to carry out puncture punching to building bottom plate in the installation of fixture, then
It is bolted to connection.This mode can damage in itself to building bottom plate so that build the puncture part of bottom plate easily
In use by rainwater or other liquid corrosions, shorten its service life.Meanwhile puncture punching can also increase using work
Sequence, made troubles to construction.And for welding support member, because welding process needs to consume the energy, and there is naked light, can be applied
Work brings certain security risk.

6, two fastening bolts 7, and two T-bolt (not shown) compositions.Wherein, bearing 4 passes through screwed hole 46 and fastening bolt 7
It is connected to one with fixture 6.Bearing is fixed on building bottom plate by T-shaped screw rod by through hole.
The fixture of upper strata connector is different from the fixture of lower floor's connector (Fig. 7 and Fig. 8).The upper strata of upper strata connector
The section of the fixture 61 generally inverted trapezoidal structure without top, bottom surface are provided with the through hole or screwed hole worn and connect fastening bolt 7.
Side is connected by connecting cylinder with the L-type fillet type turning of the bent plate, and opposite side is provided with parallel surface bottom on support I-beam 9
The supporting surface in portion.The difference of lower floor's connector and upper strata connector is：On the one hand due to I-beam lower flange to be supported bottom surface,
The length of fastening bolt 7 is longer；On the other hand a fixture 6 is only provided with, and fixture 6 is that top is provided with through hole right flank
Channel structure without bottom.The both ends of fixture 6 are connected with two fastening bolts 7, and the other end of two fastening bolts 7 is distinguished again
It is connected with the screwed hole 46 on two supporting plates 41.Thus, lower floor's fixture 62 and two fastening screws 7 form supporting construction, with
It is easy to support the bottom surface of the lower parallel surface of I-beam.The lower surface of lower floor's fixture 62, which is provided with, supplies bolted hole or groove, with
It is easy to lower floor's fixture 62 itself as the basis for installing other suspension members additional.
Fig. 9 is that mounting assembly installs axonometric drawing (omitting T-shaped screw rod) in a kind of preferred scheme of the utility model.Figure 10 is figure
9 side structure schematic view.Figure 11 is the structural representation of mounting assembly lower floor connector in a kind of preferred scheme of the utility model
Figure.It was found from Fig. 9~11, mounting assembly includes 2 lower floor's connectors and 5 upper strata connectors altogether.In the embodiment also
Including the 7 pieces of building that Open Side Down bottom plates 8 and an I-beam 9.Wherein, the top of T-shaped screw rod 10 connects through with chute 2
The cap nut of the via bottoms of bearing 4 is fixed.The both sides of the T-shaped screw rod 10 are provided with downward domatic projection, to prevent rotation screw
During cap, T-bolt 10 is rotated and can not fastened.Wherein, riser 42, the groove 3 and fin II 43 of building bottom plate coordinate, and can prevent
When fastening installation, bearing 4 is rotated centered on fastening bolt, influences to install.Meanwhile stopper slot 44 bridges I-beam
When, the riser 42 of connection supporting plate 41 can provide the stress of sufficient intensity.In this configuration, the installation process for hanging hanging piece is one
Individual assembling process, only need to by the mating connection between all parts architectural feature, without carrying out puncture punching, or
Welding operation, so that the whole faster convenience of installation process, more efficient, security is also higher, and energy consumption is then lower.
