Abstract
The invention discloses a brace screw sleeve and a pouring construction method adopting the same, relating to the field of concrete construction. A cylindrical screw sleeve made of foamed plastic or rubber is sleeved on a screw connected with a brace, a winding layer is wrapped outside the cylindrical screw sleeve so as to separate the screw from concrete, therefore, the screw sleeve can be conveniently taken down after the pouring, the screw is cut off, the brace and the screw are sealed in the concrete, and the influence on the concrete quality, which is caused by corrosion produced by the brace contacting with air and water, is avoided. The invention has low manufacture cost, convenient operation and reliable quality, is suitable to the concrete construction of small and medium sized water-power engineering, and can be also used for other concrete structures without allowing and exposing braces.
Description
Technical field
The present invention relates to concrete pouring construction method and isolated plant, particularly a kind of pouring construction method and tie rod screw sleeve that adopts the tie rod screw sleeve.
Background technology
According to the concrete construction code requirement, upstream face or the concrete that forever exposes the w face should not adopt the tie rod fixed form, because these are exposed in the water or airborne tie rod, the easy corrosion of screw rod, quality of concrete is caused damage, and form the passage of seepage.Therefore, in the construction of present major works, adopt many snap gauges plate or cantilever form usually.But construction for medium and small project; It is very uneconomic adopting many snap gauges plate or cantilever form; And the construction of many snap gauges plate or cantilever form needs higher specialized capability; Especially the position of locating cone or sleeve bolt needs accurately control, also needs big machinery to cooperate simultaneously and installs and stripping.
Summary of the invention
Technical problem to be solved by this invention provides a kind of pouring construction method and tie rod screw sleeve that adopts the tie rod screw sleeve, can after building, tie rod, screw rod be sealed in the concrete.
For solving the problems of the technologies described above, the technical scheme that the present invention adopted is: a kind of pouring construction method that adopts the tie rod screw sleeve may further comprise the steps:
1) carry out the pre-buried of earth anchor during concreting in last storehouse, mounting template is reinforced template with tie rod, screw rod, perpendicular waling, horizontal waling, chevron card, pad and nut then, and screw sleeve is installed at last;
2) twine at screw sleeve external application winding layer;
3) after building, when taking out screw sleeve, winding layer is pulled out in manual work, and screw sleeve is taken out of simultaneously, cuts off screw rod to projected depth, and it is flat to concrete surface to adopt the preshrunk mortar that hole is mended then;
Through above step, tie rod and screw rod all are sealed in the concrete.
Necessary and the template proximate of screw sleeve, the termination of screw sleeve must tightly wrap with winding layer, guarantees that concrete separates with screw rod fully.
Screw sleeve is cylindrical, in manhole is arranged, screw sleeve is provided with winding layer outward.
Screw sleeve is made up of two semicircles up and down.
Screw sleeve adopts flexible material to process.
Described flexible material comprises foamed plastics and rubber.
Described winding layer is the plastic glue strip of band gum.
Described plastic glue strip comprises polytetrafluoroethylene (PTFE).
A kind of pouring construction method and tie rod screw sleeve that adopts the tie rod screw sleeve disclosed by the invention; Through the cylindrical screw sleeve that adopts foamed plastics or rubber to make; On the screw rod that it is enclosed within tie rod is connected, and superscribe winding layer outside, screw rod and concrete are separated; After building, just can take off screw sleeve very easily like this; Cut off screw rod, tie rod and screw rod are sealed in the concrete, avoided tie rod ingress of air and water generates corrosion that concrete quality is impacted.Screw sleeve adopts two semicircles up and down; Being convenient to the installation and the taking-up of screw sleeve, is that the plastic glue strip of material carries gum with the polytetrafluoroethylene (PTFE), is convenient to sealing between screw sleeve and screw rod and the template; And the polytetrafluoroethylene (PTFE) material is difficult for and the concrete adhesion; Be convenient to take out, the shape of winding can make that to build the endoporus that the back concrete forms comparatively coarse, is convenient to the later stage hole is sealed.
The present invention is simple in structure, low preparation cost, easy and simple to handle, reliable in quality.Be applicable to the concrete construction of medium and small-scale water and electricity engineering, also can be used for the concrete structure that other do not allow and should not expose tie rod.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the present invention is described further.
Fig. 1 is the embodiment of the present invention sketch map;
Fig. 2 is a flexible material cross sectional representation among the present invention;
Fig. 3 is the whole cross sectional representation of the present invention.
The specific embodiment
Like Fig. 1, Fig. 2 and shown in Figure 3, a kind of pouring construction method that adopts the tie rod screw sleeve may further comprise the steps:
1) carry out the pre-buried of earth anchor 1 in last storehouse during concreting, mounting template 5 then, reinforce with tie rod 2, screw rod 3, perpendicular waling 6, horizontal waling 7, chevron card 8 and pad and 9 pairs of templates 5 of nut, and screw sleeve 4 is installed at last;
2) twine at screw sleeve 4 external application winding layers 11;
3) after building, when taking out screw sleeve 4, winding layer 11 is pulled out in manual work, and screw sleeve 4 is taken out of simultaneously, cuts off screw rod 3 to projected depth, and it is flat to concrete surface to adopt the preshrunk mortar that hole is mended then;
Through above step, tie rod 2 all is sealed in the concrete with screw rod 3.
Screw sleeve 4 must be close to template 5, and the termination of screw sleeve 4 must tightly wrap with winding layer 11, guarantees that concrete separates with screw rod 3 fully.
Screw sleeve 4 is cylindrical, in manhole is arranged, the outer winding layers 11 that are provided with of screw sleeve 4.
Screw sleeve 4 is made up of two semicircles up and down.
Screw sleeve 4 adopts flexible material to process.
Described flexible material comprises foamed plastics and rubber.
Described winding layer 11 is the plastic glue strip of band gum.
Described plastic glue strip comprises polytetrafluoroethylene (PTFE).
In Fig. 1; Concrete blinding form of construction work according to general is carried out formwork erection; At first carry out the pre-buried of earth anchor 1 during concreting in last storehouse; Mounting template 5 then, reinforce with tie rod 2, screw rod 3, perpendicular waling 6, horizontal waling 7, chevron card 8 and pad and 9 pairs of templates 5 of nut, and screw sleeve 4 is installed at last.
In Fig. 2, customize the foamed plastics and the rubber of solid shape on request, its length, thickness, center bore can confirm as required, the flexible material cross section that customization is good be two semicircles up and down, is convenient to installation and takes off.
In Fig. 3, screw sleeve 4 is enclosed within on the screw rod 3, the outside uses polytetrafluoroethylene (PTFE) to twine as the winding layer 11 of material.Be noted that screw sleeve 4 must be close to template 5, the termination of screw sleeve 4 must tightly wrap with winding layer 11, guarantees concrete and screw rod 3 and separates fully, is convenient to screw sleeve 4 is taken out.
When taking out screw sleeve 4, winding layer 11 is pulled out in manual work, can screw sleeve 4 be taken out of simultaneously, if any residual, can adopt iron wire that its hook is gone out.After screw sleeve 4 takes out, will stay the hole of rule on the concrete surface, and the hole inner wall coarse.Adopt cutter that screw rod 3 is cut off to projected depth, it is flat to concrete surface to adopt the preshrunk mortar that hole is mended then.
