Description
Technical field
The utility model relates to the location and the fastening devices of construction formwork, relates to a kind of concrete wall formwork reinforcement screw rod especially.
Background technology
At the concrete wall, when being casting reinforced coagulating cement cob wall process, existing method is at many isometric bar reinforcements of the on-the-spot intercepting of cast, then respectively with between iron wire or other elongated bundled pieces across being tied on the reinforced frame, plank is set up at two ends at bar reinforcement, then injects cement concrete and obtain the reinforced cement concrete wall in plank.But preceding method has the following disadvantages: one, be difficult to be consistent in the on-the-spot bar reinforcement length that obtains of cast, the process of intercepting reinforcing bar is pure manual operations, has certain error unavoidably, and finally influences the uniformity and the uniformity of thickness of wall body; Two, the value ratio of bar reinforcement is higher, has increased building costs; When three, being fixed to bar reinforcement on the reinforced frame, need to use bar reinforcement iron wire or other elongated connectors in addition itself, fixation procedure is cumbersome, and efficiency of construction is low.
Also having a kind of mode is to adopt in the template outside it is positioned, but the scale error of the reinforced cement concrete wall of making in this way is bigger, is difficult to reach the quality requirement of construction formwork construction, can't guarantee construction quality.
It is to use elongating screw rod with a kind of reinforcing that runs through the reinforced cement concrete body of wall that a kind of mode is arranged in the prior art again, then with nut location and fixed form, but this mode can be cemented in long bolt in the reinforced cement concrete body of wall simultaneously, causes a large amount of raw-material wastes.
When pouring into a mould underground reinforced concrete concrete wall, existing mode is to adopt the wall thickness two ends that have the sealing sheet to be provided with the long bolt of reinforcing bar electric welding location, concrete wall template is run through at the long bolt two ends, after the concrete wall is used nut fixed length screw rod with the outside of template, to placing cement concrete in injection wherein, can obtain thickness of wall body evenly, consistent and have a reinforced concrete coagulation wall of sealing performance.But the part long bolt that this reinforcing mode need adopt the mode of artificial cutting to remove to expose the reinforced concrete metope had both caused the waste of material, had also increased operating procedure simultaneously.
The utility model content
