Abstract
The utility model relates to a single-head split bolt for underground continuous wall inner lining wall shuttering erection, which is characterized by comprising a single-head split bolt (4) and a nodal steel plate (5); the bottom end of the single-head split bolt (4) is fixedly welded onto the nodal steel plate (5); and the single-head split bolt (4) for positioning an inner lining wall shuttering is welded onto a continuous wall main reinforcing bar (2) through the nodal steel plate (5). By welding the single-head split bolt with the nodal steel plate in advance, the single-head split bolt can be installed only by welding the nodal steel plate with the continuous wall main reinforcing bar. The single-head split bolt with simple structure, easy manufacture and convenient operation reduces construction difficulty, improves stress characteristics, ensures construction quality and safety and has strong pertinence, and the construction technique is easy to be popularized.
Description
Technical field
The utility model belongs to underground wall body structure reverse construction field, particularly relates to a kind of underground Whirlwind tank, hot-tub construction formwork supporting parts.
Background technology
Generally in the underground structure reverse construction,, when building inwall, can't use the double end split bolt that template is positioned owing to use diaphragm wall.Conventional way is that diaphragm wall 1 is dug out diaphragm wall master muscle 2, and single head split bolt 4 one end crotches weld after hooking this main muscle.As Fig. 2, because that concrete cuts difficulty is bigger, often the workman can not do on request in strictness, but a curved quarter bend 6, on diaphragm wall master muscle 2, this node is when tension with 3 overlap weldings of single head split bolt, have moderate finite deformation, the commissure produces stress and concentrates, and has hidden danger of quality.Therefore, need to adopt a kind of new diaphragm wall inwall formwork to replace original way: to be used for underground wall body structure reverse construction with the single head split bolt.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of diaphragm wall inwall formwork single head split bolt, to solve constructional difficulties in the prior art, the defective of node resistance to tension difference.
A kind of diaphragm wall inwall formwork single head split bolt, constitute by single head split bolt and node steel plate, described node steel plate is fixed on the bottom of single head split bolt, and described single head split bolt is welded to location inwall template on the diaphragm wall master muscle by the node steel plate.
Fixing between described single head split bolt and the node steel plate by welding.
The described twin fillet wolt that is welded as connects.
Beneficial effect
The utility model is by welding single head split bolt and a node steel plate in advance, only need during installation node steel plate and the weldering of diaphragm wall master muscle are got final product, simple structure, make easily, easy to operate, reduced difficulty of construction, improved mechanical characteristic, guaranteed construction quality and safety, and with strong points, promote this construction technology easily.

Fig. 2 is existing single head split bolt connected node schematic diagram;
Fig. 3 is the utility model connected node schematic diagram.
The specific embodiment
Below in conjunction with specific embodiment, further set forth the utility model.Should be understood that these embodiment only to be used to the utility model is described and be not used in the restriction scope of the present utility model.Should be understood that in addition those skilled in the art can make various changes or modifications the utility model after the content of having read the utility model instruction, these equivalent form of values fall within the application's appended claims institute restricted portion equally.
Embodiment 1
A kind of diaphragm wall inwall formwork single head split bolt, constitute by single head split bolt 4 and node steel plate 5, described node steel plate 5 twin fillet wolts are connected the bottom of single head split bolt 4, described single head split bolt 4 is welded to location inwall template 3 on the diaphragm wall master muscle 2 by node steel plate 5, and is fixing by welding between described single head split bolt 4 and the node steel plate 5.
As shown in Figure 3, during installation, need are installed the diaphragm wall 1 of split bolt position and dug out the exterior face that exposes diaphragm wall master muscle 2,, be used to locate inwall template 3 prefabricated node steel plate 5 and the 2 two-sided welding of diaphragm wall master muscle.
Claims (3)
1. diaphragm wall inwall formwork single head split bolt, it is characterized in that: constitute by single head split bolt (4) and node steel plate (5), the bottom of described single head split bolt (4) is weldingly fixed on the node steel plate (5), and described single head split bolt (4) is welded on the diaphragm wall master muscle (2) by node steel plate (5).
2. diaphragm wall inwall formwork single head split bolt as claimed in claim 1 is characterized in that: fixing by welding between described single head split bolt (4) and the node steel plate (5).
