Abstract
The invention relates to a novel method for embedding anchor bars in concrete. By the adoption of the method, holes do not need to be dug in a formwork, so that template consumption is reduced, working efficiency is improved and construction cost is reduced. According to the technical scheme, the method is characterized by comprising the steps of 1, conducting threaded connection of first-phase anchor bars and a straight thread sleeve, wherein the other end of the sleeve is attached to a formwork, and the sleeve is filled with cotton fabric; 2, embedding the first-phase anchor bars connected with the straight thread sleeve in first-phase concrete; 3, taking the cotton fabric in the straight thread sleeve out after first-phase concrete pouring is finished and the formwork is removed; 4, conducting threaded connection of second-phase anchor bars. The method is suitable for anchor bar embedding during concrete pouring of hydraulic and hydroelectric engineering, constructional engineering and other similar engineering.
Description
Technical field
The present invention relates to a kind of method of pre-buried dowel in concrete. It is mainly used in pre-buried dowel when Hydraulic and Hydro-Power Engineering, architectural engineering and other similar engineering concreting.
Background technology
In Hydraulic and Hydro-Power Engineering, architectural engineering, often refer to pre-buried dowel in concrete, a dowel part is embedded in fist stage concrete together builds with fist stage concrete, another part stretches out fist stage concrete, later stage builds into second stage concrete or is connected with other structures, and dowel plays a part to connect power transmission. The mode that traditional pre-buried dowel construction is typically employed in template perforate, namely needing to bury underground cutting hole in the template position that dowel position is corresponding, stretches out dowel. Dowel bury underground quantity more time, this kind of mode efficiency of construction is low, and template waste is big, especially at present in Construction for Hydroelectric Project, in order to improve concrete pouring quality and efficiency, widely used large-scale customized steel form, the template loss that template perforate causes will be greatly increased construction cost.
Summary of the invention
The technical problem to be solved in the present invention is: for the problems referred to above, it is provided that a kind of brand-new method of pre-buried dowel in concrete, and the method need not dig hole in template, thus template loss can be reduced, improves work efficiency, reduces construction cost.
The technical solution adopted in the present invention is: a kind of method of pre-buried dowel in concrete, it is characterised in that comprise the following steps:
1. being threadeded with straight screw sleeve by a phase dowel, the other end of this sleeve is adjacent to template, and sleeve inner adopts bafta to fill;
2. the phase dowel being connected with straight screw sleeve is buried underground in fist stage concrete;
3. built after form removal until fist stage concrete, taken out the bafta being filled in straight screw sleeve;
4. threaded second phase dowel.
The invention has the beneficial effects as follows: 1), compensate for the deficiency of now widely used pre-buried dowel construction method, it is to avoid template perforate, decrease the loss of template, reduce construction cost; 2), owing to avoiding template perforate, and then avoid tapping spillage during concreting, while improve concrete pouring quality, ensure that concrete good looking appearance; 3), for needing the building of a large amount of pre-buried dowel, this form of construction work has simple in construction, good reliability, the construction interference advantage such as little, is greatly improved efficiency of construction.
Accompanying drawing explanation
Fig. 1 is the structural representation of the pre-buried phase dowel of the present invention.
Fig. 2 is the structural representation that the present invention connects second phase dowel.
Detailed description of the invention
The present embodiment is the method for pre-buried dowel in concrete, specifically includes following steps:
1. as shown in Figure 1, during pre-buried dowel, dowel is disconnected, divided for two phases carried out, first a phase dowel 2 is threadeded with straight screw sleeve 3, the other end of this sleeve is adjacent to template 4, sleeve inner (does not coordinate dowel part) and adopts bafta (gauze or cotton or both) to fill, it is prevented that during concreting, serosity enters in sleeve;
2. the phase dowel 2 being connected with straight screw sleeve 3 is buried underground in fist stage concrete 1;
3. built after form removal 4 until fist stage concrete 1, taken out the bafta being filled in straight screw sleeve 3;
4. threaded second phase dowel 5, as in figure 2 it is shown, at this moment second phase dowel 5 is connected with a phase dowel 2 and is anchored in fist stage concrete 1, possesses and connects power transmission condition, builds for the later stage and gets ready into second stage concrete or be connected with other structures.
It is a kind of steel concrete supporting mode of allowing of relevant Regulations that the straight screw sleeve adopted in the present invention connects, and has that technique is simple, an advantage of dependable performance and economical rationality, and the thread making of dowel and sleeve are installed and should be met corresponding Regulations requirement.
