Description
Technical field
The present invention relates to a kind of steel construction embedding anchor bolts construction method, become more meticulous pre-buried structure construction method particularly to the steel construction foundation bolt shaper that a kind of can effectively shorten on-site construction time, improve foundation bolt positioning precision, belong to building engineering field, it is adaptable to steel construction foundation bolt construction work.
Background technology
In recent years, along with the fast development of urban construction, steel building application is more and more universal.In Construction of Steel Structure, installation quality and the positional accuracy of steel construction foundation bolt are prominent on safety and the construction quality impact of steel construction.
Existing a kind of combined multifunctional foundation bolt locating template, the connected mode that the framework of template is nested within big steel part according to small steel piece by four telescoping rods is in turn connected to form；The U type groove of the U-shaped steel part in lower end of connector is stuck on telescoping rod, and is connected by bolt and telescoping rod are fixing；Foundation bolt fixed standard part is through two through holes of U shaped steel side, connector upper end, and is connected by bolt and connector are fixing.Though this structure from the position of adjustment foundation bolt horizontal, vertical, but can be difficult to the connection strengthening foundation bolt with foundation soil, and the installation of this structure is complicated, location workload is big.
One foot bolt Embedment Construction engineering method accurately, take making high-precision positioning fixture, the pre-embedded anchoring bolts often organizing equipment Foundations is carried out clustered control, and sprung jaws is set outside foundation bolt, and the leg on sprung jaws is embedded in the screens hole on positioning fixture, spring clamp is fastened on foundation bolt positioning fixture, reinforces foundation bolt further, prevents foundation bolt from loosening.Though this construction method can prevent foundation bolt from loosening problem, but is difficult to be adjusted foundation bolt locus, and Contraction in Site amount is big, be difficult to effectively promote foundation bolt positioning precision.
In sum, though the construction technology of existing steel construction foundation bolt, structure achieve preferable project benefit under suitable operating mode, but remain certain shortcoming, be mainly reflected in: the design of foundation bolt location structure owes rationally, foundation bolt positioning precision is low, structure integrated connection intensity not enough, structure site operation assembles the aspects such as difficulty is big.Given this, it is actually needed based on current position foot bolt is pinpoint, the most urgently invents and a kind of can effectively shorten on-the-spot foundation bolt and the time of location is installed, promotes the accuracy of foundation bolt location, reduce base concrete and pour the steel construction embedding anchor bolts construction method on the impact of foundation bolt locus.
Summary of the invention
It is an object of the invention to provide and a kind of can effectively shorten on-the-spot foundation bolt and the time of location is installed, promotes the accuracy of foundation bolt location, reduce base concrete and pour the steel construction foundation bolt shaper on the impact of foundation bolt locus and become more meticulous pre-buried structure construction method.
For realizing above-mentioned technical purpose, present invention employs techniques below scheme:
A kind of steel construction foundation bolt shaper becomes more meticulous pre-buried structure construction method, including following construction procedure:
1) foundation bolt locus test: according to the design requirement of steel structure column foundation bolt, the diameter of foot bolt definitely, and assemble the caging bolt aperture through hole；
2) assemble mould bases assemble: template top, bottom set gradually lower location-plate, vertical spacing base plate, vertical spacing top board, on location-plate and top template, vertical spacing base plate, vertical spacing top board control it by cross spacing arc plate and vertically spend, limit its horizontal level by upper limit plate, make the caging bolt that assembles of bottom template determine the assembling caging bolt of plate and upper location-plate through hole through lower simultaneously；Then by assembly and connection bolt through assembly and connection bolt through hole, and lower location-plate is connected firmly with upper location-plate, top template；
