Description
Technical field
The invention belongs to building structure technology field, more particularly to a kind of fabricated shear wall superimposed sheet connecting integration
Support system and installation method.
Background technology
Growing with assembled architecture, each component connection of assembled architecture will also become frequent and important.
In the connection of assembled arthitecutral structure component, shear wall-superimposed sheet connection is a kind of very common presence.In this type of attachment
In, one end of superimposed sheet is overlapped on the edge of shear wall, and the top of plate is sling by crane, and bottom carries out vertical supporting.
And shear wall-superimposed sheet connecting node is primarily present three problems:
First, the problem of superimposed sheet bearing length.For shear wall, its protective layer is generally 15-20mm.Taken in practical structures
When connecing, since the operation of the scale error of component, construction personnel is horizontal and the factors such as the construction environment at scene, usually very
It is difficult accurately smoothly to complete overlap joint, generally require multidisciplinary personnel and coordinate for several times, adjustment could be completed repeatedly, while be difficult to protect
Card overlap joint quality.
Second, at the posterior nodal point of shear wall-superimposed sheet overlap joint after pour problem.Superimposed sheet is overlapped on shear wall it
Afterwards, side template can be applied to wearing bolt, but the support of end template will be sufficiently complex, in the case where that can not ensure to overlap quality,
The support effect of end template can not equally ensure, finally influence connection stiffness.
3rd, the installation of vertical supporting and problem is removed under superimposed sheet.To ensure security, the vertical supporting of superimposed sheet is past
Past very complicated, installation procedure is more and complicated.Meanwhile substantial amounts of vertical supporting reduces the activity space of bottom.
The content of the invention
Shuttering supporting is poured for the above-mentioned wall lap of splice at fabricated shear wall superimposed sheet connecting node deficiency, after node
And the technical problems such as assembling and disassembling is cumbersome are supported under plate, the present invention provides a kind of for the connection of fabricated shear wall superimposed sheet

Embodiment
The present invention will be described in detail with specific embodiment below in conjunction with the accompanying drawings.
Embodiment 1
As shown in figs 1 to 6, a kind of fabricated shear wall superimposed sheet connecting integration support system of the present invention, including be symmetrical arranged
Supporting rack 3 in 5 side of shear wall, the adjusting bolt 4 and support plate 6 set between supporting rack 3 and superimposed sheet 1, the support
Frame 3 is set up in parallel two along shear wall 5 per side, and the section of supporting rack 3 is irregular frame, its right-angle side corresponds to shear wall respectively
5 and superimposed sheet 1, it is provided with the right-angle side with respect to 5 side of shear wall and is bolted preformed hole, is bolted to shear wall 5
The embedded nut 2 that side is set；Relative to connection adjusting bolt 4 on the right-angle side of superimposed sheet 1, when in use, 5 homonymy of shear wall
Connection support plate 6, superimposed sheet 1 are placed in adjacent two supporting racks, 3 upper backup pad of side shear wall 5 in adjusting bolt 4 on supporting rack 3
6 top, the height of support plate 6 is adjusted by the adjusting bolt 4 between adjusting between support plate 6 and supporting rack 3.
As Figure 4-Figure 6, wherein support frame as described above 3 be by two irregular frames by connecting plate connect and compose one it is whole
Body, the right-angle side of its irregular frame are welded by equal leg angle, other are welded by steel plate；Supporting rack 3 is used for branch
Support top superimposed sheet 1.
As Figure 7-9, the adjusting bolt 4 is mounted between support plate 6 and supporting rack 3, by adjusting adjusting bolt 4
Highly finely tune the level height of support plate 6.
As shown in Fig. 1, Figure 12 and Figure 13,2 periphery of embedded nut set on the shear wall 5 is also respectively provided with symmetrically
Inclined 7 reinforcement of U-shaped muscle；The inclined angle of 7 relative level of U-shaped muscle is 30-45 °, and this example selects 45 °.
As shown in Figure 1, setting 4 embedded nuts 2 on the shear wall 5 per side, the embedded nut 2 of both sides is located at same water
On horizontal line；Supporting rack 3 is bolted on the embedded nut 2 in shear wall 5, and the load on superimposed sheet 1 passes through supporting rack 3
Embedded nut 2 is transmitted to, further passes to shear wall 5；Two 2 connecting holes of embedded nut are provided with supporting rack 3, are selected suitable
Embedded nut 2, embedded nut 2 is connected with preformed hole of the supporting bolt of embedded nut 2 through relevant position, so that fixed branch
Support 3；Single 2 connecting hole of embedded nut can ensure it is easy for construction, but there are the problem of the rotation of supporting rack 3, and when pre-
Bury 2 connecting hole of nut it is excessive when, then the docking difficulty of 2 connecting hole of embedded nut when can undoubtedly increase construction, so using oval
2 connecting hole of embedded nut of type, can both prevent the rotation of supporting rack 3, the also height of fine-tuning supporting rack 3, and can be effectively
Reduce difficulty of construction.
As shown in Figure 2 and Figure 3, the present invention is used for the application method of the supporting rack 3 of fabricated shear wall superimposed sheet connection, bag
Include following steps：
（1）Supporting rack 3 is symmetrically disposed on 5 both sides of shear wall two-by-two, the side of supporting rack 3 passes through with 5 side of shear wall respectively
The supporting of embedded nut 2 is bolted embedded nut 2, and bolt need not tighten fixation；
（2）3 top surface of supporting rack is measured by spirit level, it is ensured that the top surface gap of four supporting racks 3 is less than 5mm, tightens
Bolt；
（3）Support plate 6 is connected by adjusting bolt 4 with supporting rack 3, and support plate 6 is positioned on two supporting racks 3, then into
Second of spirit level measurement of row；
（4）Finely tuned by adjusting bolt 4, it is ensured that support plate 6 is parallel to floor；
（5）Lifting superimposed sheet 1 is placed on support plate 6, connects 5 node of superimposed sheet 1 and shear wall, and poured.
When the node poured reaches the intensity of code requirement, the dismounting of structure is supported；Method is as follows：
（1）The adjusting bolt 4 in support plate 6 is loosened, removes support plate 6；
（2）The embedded nut 2 and the supporting bolt of embedded nut 2 that release supporting rack 3 is connected with shear wall 5, remove supporting rack 3.
The present invention Path of Force Transfer be：Superimposed sheet 1 is to supporting rack 3, then by supporting rack 3 to embedded nut 2, by embedded nut
2 are transmitted to shear wall 5.So 3 bearing capacity of supporting rack depends on the coagulation at the self-strength and embedded nut 2 of embedded nut 2
Native intensity, in order to make embedded nut 2 based on drawing stress, so adjusting bolt 4 and support plate 6 are arranged at connection system for guide rail
Distal end；Meanwhile it is that the pre-embedded bolt at shear wall 5 adds U-shaped muscle 7 to carry out reinforcement.
Embodiment 2
This example is as different from Example 1：2 periphery of embedded nut set on shear wall 5 described in this example is equipped with U-shaped 7 phase of muscle
It it is 30 ° to the inclined angle of horizontal plane.This example support plate 6 using by welded steel plate into a groove profile frame.As Figure 10,
Shown in Figure 11, the termination that embedded nut 2 described in this example is not connected to bolt carries block 8, and the block 8 is set along the termination circumference
In cross-shaped configuration, fixed beneficial to installation.
Embodiment 3
This example is as different from Example 1：2 periphery of embedded nut set on composite beam 5 described in this example is equipped with U-shaped 7 phase of muscle
It it is 40 ° to the inclined angle of horizontal plane.
