Abstract

A method for inserling reinforcing bars to building and its apparatus are disclosed. An exchangeable temporary rod passes through the shuttering at the position where the reinforcing bar is to be added and is divided into temporarily embedded segment in grouting space inside the shuttering and holding segment outside the shuttering. After concrete is poured into the pouring space and before the concrete is at the initial setting stage, the exchangeable rod is drawn out to form a preserved hole. Finally, the reinforcing bar is inserted into the preserved hole, leading to quick, safe and convenient addition of reinforcing bars.

Description

Adding ribs to building method and device thereof

The invention relates to a kind of adding ribs to building method and device thereof, particularly relate to and to make building in quick, convenient, the clean more and safety of the bar planting work in the secondary construction.

Press, in the fortification of general group shuttering concrete perfusion with formation reinforced concrete buildings body, for easy construction, its main structure is the main body wall for example, floor building version .... etc., all elder generation organizes upright with common template layer by layer according to the normal specifications mode and is in the milk and the formation agent structure; " aggregated(particle) structure body " as for some non-main structure bodies, then must in so-called " secondary construction ", be in the milk in addition and be finished, the for example two-layer stair corner face between the version downstairs of going up, or as " flying beam " of non-main structure beam, or not the partial structurtes body in agent structure such as railing, enclosure wall, local wall, beam, post and building version etc., all need to finish Hou, just carry out the secondary construction in agent structure.

Because the structure of these secondary constructions all must be combined into one with the main structure body, must link with reinforcing bar between the new-old concrete structure of therefore preceding Hou time construction, set-up modes of these binding reinforcing bars have two:

One is pre-buried type, see also shown in Figure 1, be when the first time, the agent structure body was in the milk, to link reinforcing bar 11 is embedded in the concrete 10 in advance, its pre-buried mode is embedded in the concrete for the connected section 12 that will link reinforcing bar 11 bends whole in advance in advance, when waiting to desire to carry out the secondary construction, be about near the connected section 12 13 dozens of concrete divided by exposing connected section 12, pull the connected section 12 of bending straight again and it is directly stretched expose, shown in label 12 ', wrap up in knot for new (secondary construction) concrete 10 ' perfusion and use.If the reinforcing bar that the binding reinforcing bar of this kind pre-buried type 11 is thicker then in bending and pull in the straight work very effort, even can't bend.

Another plants formula after being, see also shown in Figure 2, it is that the grouting of in advance finishing agent structure concrete 20 is shaped, when waiting to desire to carry out the secondary construction, promptly link the reinforcing bar place and carry out the work of heeling-in reinforcing bar at needs, it is prior to get out the bar planting hole 21 of desired depth on the concrete wall with electric drill substantially, and perfusion anchor knot is wrapped up in the chemical agent 22 (sticking together cream) that share in this hole, to link reinforcing bar 23 again implants in the bar planting hole 21, utilize the condense knot power of wrapping up in of Hou of medicament to make and link reinforcing bar 23 and plant admittedly in concrete 20, its revealed section 24 can be wrapped up in knot usefulness for new (secondary construction) concrete spouting.

The bar planting construction method that this Hou is planted formula has the place of its inconvenience, when boring, can produce noise first, and the concrete powder that boring the time flies out from the hole also can cause air pollution, moreover boring the time might be got into pipeline pre-buried in the concrete, and the work of boring is one by one taken a lot of work and time-consuming, because of boring work above-mentioned trouble existence is arranged again, during therefore actual boring, the staff often is reluctant or is undrillable too dark, so promptly cause the bar planting hole too shallow, it is too short to wrap up in knot length, even the knot of wrapping up in of chemical agent is arranged, still less certain, and must improve the bar planting number.

Main purpose of the present invention is to provide a kind of adding ribs to building method and device thereof, its can make the bar planting work of building in secondary construction more fast, convenient, clean and safety.
