Abstract
The utility model discloses a structural design of detachable wall bolt used to fix template. The detachable wall bolt comprises a wall screw (6) with water stop plate and two fastening screws (7). One end of the fastening screws is with external thread and the other end of the fastening screws with internal screw port is sleeved by a conical plastic pipe casing. After removing formwork of the pouring concrete wall, the two fastening screws of the wall bolt can be screwed off by wrench to be reused for many times, therefore, the process of cutting a plurality of bare steel bars in the wall by gas welding after removing formwork of pouring concrete is solved, simultaneously, massive steel resources are saved.
Description
The utility model relates to the structure design category of the through-wall bolt spare that is used for fixing template, specifically, relates to the structure design category of the through-wall bolt spare that has the sealing sheet.
On the building site, people usually can see at the concrete wall surface exposure and go out reinforcing bar one by one, these reinforcing bars that expose body of wall are used for fixing the through-wall bolt spare of template when being the fluid concrete body of wall, traditional through-wall bolt spare, the through-wall bolt spare that particularly has sealing sheet [1], mainly be that the last square iron of welding is made (see figure 1) in the middle of having externally threaded shank of bolt with two ends, its length is that the thickness of the thickness according to concrete wall, the flitch thickness that adds fixed form and use and pad [2] is determined.During use, get final product at the through-wall bolt two ends covers Upper gasket clamp nut [3] of screwing on.Generally, the thickness of template [4] and flitch [5] and pad is all at the 200-300 millimeter, that is to say, if by 260 millimeters calculating, the shank of bolt length on body of wall both sides just needs 520 millimeters, fixes template and has broken concrete, after the form removal, concrete wall surface just exposes reinforcing bar one by one, and these reinforcing bars that expose metope cut down with gas welding again.This shows, pour into a mould the concrete wall of 200 millimeters thick, just need the through-wall bolt spare of 720 millimeters long, after wall form is removed, a through-wall bolt spare will have the reinforcing bar of 520 millimeters long to be cut down by gas welding becomes steel scrap, has caused the waste of great deal of steel.
The purpose of this utility model is a kind of detachable through-wall bolt spare of being made up of through-wall bolt bar [6] and two fastening screw tightening latches [7] that is used for fixing template of design, after the concrete wall form removal, the available spanner of fastening screw tightening latch [7] of detachable through-wall bolt spare screws down repeatedly and uses, thereby saves great deal of steel.
Realize that specific design of the present utility model is:
The detachable through-wall bolt spare that is used for fixing template of the present utility model is made up of through-wall bolt bar [6] and the two fastening screw tightening latches [7] that have sealing sheet [1], the fastening screw tightening latch is one one an end band external screw thread, in the other end band screw socket and in band the outside of screw socket one end be with the shank of bolt of the plastic pipe sleeve [8] of a platform taper, be provided with symmetrical plane near on the shank of bolt pole face of plastic pipe sleeve one end in addition, an end of screw socket is connected with through-wall bolt bar [6] one ends in fastening screw tightening latch [7] band, makes a through-wall bolt bar [6] and two fastening screw tightening latches [8] connect to form a detachable through-wall bolt spare [9] that is used for fixing template.
Adopt the detachable through-wall bolt spare that is used for fixing template of the utility model design, after the concrete wall form removal, available spanner screws down two fastening screw tightening latches on the through-wall bolt spare repeatedly and uses, the operation that exposed one by one reinforcing bar cuts down with gas welding on having solved after having played the concrete form removal body of wall, simultaneously, can save a large amount of steel resources.
