The pre-buried shaper of using of factory building columns stone bolt
Technical field:
The utility model relates to the mould that uses in the base concrete pouring construction, the pre-buried shaper of using of especially a kind of factory building columns stone bolt.
Background technology:
At present, during the base concrete pouring construction, adopt steel materials such as angle steel, channel-section steel to make the stone bolt fixed mount, complex procedures, after construction was finished, the bolt frame also was embedded in the concrete, caused the steel waste, had increased construction costs.ZL02270506.6 discloses a kind of pre-embedded anchoring bolts locating support, though displacement or inclination are accurately located, prevented to produce to stone bolt can guarantee to build the time, the column part that its angle steel is made still is embedded in the concrete, can not reuse.
Summary of the invention:
The technical problems to be solved in the utility model is: a kind of utilization perforating on bamboo (wood) offset plate is provided, last lower nut is fixed, as the bolt frame, be different from the bolt frame that adopts the steel welding, make it to have enough to meet the need use, reduce the pre-buried shaper of using of factory building columns stone bolt of engineering construction cost.
The technical scheme that addresses the above problem employing is: the pre-buried shaper of using of a kind of factory building columns stone bolt, comprise that material is the location-plate of bamboo offset plate or wood glue plate, the flitch cross-arm, described location-plate is arranged at intervals with on it and every group of bolt positioning control hole one to one, described flitch cross-arm is divided into every row's bolt both sides, its two ends are suitable for reading affixed by steel nail and short column template, this location-plate is tiled on this flitch cross-arm, both are connected and fixed by steel nail, the positioning control hole on the pairing location-plate is passed in every row's bolt upper end, and by last, lower nut is fixedlyed connected with this location-plate.
Compared with prior art, the beneficial effects of the utility model are: efficiency of construction improves greatly, and construction precision reaches code requirement, and bamboo (wood) offset plate mould cost is low and can have enough to meet the need use, construction cost reduces greatly, is particularly useful for the similar engineering of bolt group number size in the industrial premises.

The specific embodiment:
The utility model is described in further detail below in conjunction with drawings and Examples.
The pre-buried shaper of using of the described factory building columns stone bolt of present embodiment is made of location-plate 1, flitch cross-arm 2, steel nail 4, nut 6, and location-plate 1 adopts thick bamboo offset plate of 12mm or the thick wood glue plate of 20mm to make, and flitch cross-arm 2 specifications are 60 * 90mm.
The requirement that the size of location-plate 1 is put 200mm outward by relative one group of bolt 7 axis of location-plate 1 outward flange is made, the spacing of pressing bolt 7 in the drawing is provided with on location-plate 1 and every group of bolt 7 positioning control hole 3 one to one at interval, and the aperture in positioning control hole 3 is greater than diameter of bolt 0.5mm.
A flitch cross-arm 2 is placed in the both sides of every row's bolt 7, and flitch cross-arm 2 is no more than 20mm with the edge spacing of nut 6.Flitch cross-arm 2 two ends are affixed by steel nail 4 and short column template suitable for reading 5, location-plate 1 is tiled on the flitch cross-arm 2, both are connected and fixed by steel nail 4, and pairing positioning control hole 3 is passed in every row's bolt 7 upper ends, and fixedly connected with location-plate 1 by upper and lower nut 6.
Because bolt 7 relies on location-plate 1 and is fixedly connected, be to guarantee bolt 7 pre-buried precision, the support that must guarantee bolt 7 footing firmly and forbid to reduce the strong point in Fig. 2, has increased to socket at the footing place of bolt 7 and has used reinforcing bar 8.In addition, bolt 7 upper end screw threads will be with adhesive tape with its parcel protection.
