Abstract

A foundation bolt positioning template of a steel-structure building is provided with a rectangular frame steel plate which is 8-10 mm thick. A frame surface opposite to the rectangular frame steel plate is respectively provided with through bolt holes matched with foundation bolts at the upper end of a concrete independent foundation. The diameters of the through bolt holes are larger than the diameters of the matched foundation bolts by 2 mm. The distances from the centers of the through bolt holes to adjacent outer edges of the rectangular frame steel plate range from 100 mm to 200 mm. The distance from a center connecting line of the through bolt holes to an adjacent inner hole edge of the rectangular frame steel plate is 100 mm. In addition, two opposite lateral frame edges are 100 mm wide. The foundation bolt positioning template has simple structure, is conveniently used and can lead to the relatively high accuracy of the form and position of the embedded foundation bolts at the upper end of the concrete independent foundation.

Description

Steel building stone bolt locating template

Technical field

The utility model relates to the stone bolt location instrument of using aid, particularly a kind of steel building when a kind of steel building is constructed.

Background technology

Steel building has concrete foundation, and the steel work main body is mounted on the concrete foundation.For the steel work main body is installed on the concrete foundation, want pre-buried a large amount of stone bolt on the concrete foundation, with stone bolt steel work main body and concrete foundation are linked up during construction.A large amount of stone bolt generally is the upper end that is embedded in a plurality of concrete single footing by the designing requirement grouping, all upper surfaces, concrete single footing are on same horizontal plane, the one group of stone bolt that is embedded in upper end, concrete single footing generally is the both sides, innner and outer that are distributed in upper surface, concrete single footing, upper surface, concrete single footing generally is a rectangle, and the stone bolt that is embedded in the upper end of concrete single footing is distributed in the both sides, innner and outer of the rectangle upper surface of concrete single footing by designing requirement.There is installing plate the lower end of steel work main body column, the shape and size of steel work main body column lower end installing plate match with the shape and size of upper surface, concrete single footing, the bolt hole of wearing that matches with one group of pre-embedded anchoring bolts of upper end, concrete single footing is arranged on the steel work main body column lower end installing plate, during installation, wearing on one group of stone bolt that bolt hole is enclosed within single footing upper end of steel work main body column lower end installing plate is installed in the steel work main body on the concrete foundation with nut is fastening again.When the steel work main body is installed on the stone bolt, the accuracy of form and position that is embedded in the stone bolt of upper end, concrete single footing greatly influences the installation of steel work main body, therefore, controlling the morpheme parameters such as plan-position, absolute altitude, pitch of bolts and verticality of stone bolt during pre-embedded anchoring bolts well on concrete foundation is that emphasis in the building operations also is a difficult point.In the prior art, on concrete foundation during pre-embedded anchoring bolts, the special tool that does not have the stone bolt location, during pre-embedded anchoring bolts, have and adopt the preformed hole job practices of pre-embedded anchoring bolts again, also have in the upper end of concrete single footing single group the job practices of foot bolt regularly, cumbersome, the inefficiency of these job practices operations, particularly the accuracy of form and position of pre-embedded anchoring bolts is lower, causes the steel work main body that difficulty is installed.

Summary of the invention

The purpose of this utility model is in order to overcome above-mentioned deficiency, to propose a kind of higher steel building stone bolt locating template of the accuracy of form and position that can make upper end, concrete single footing pre-embedded anchoring bolts when the pre-embedded anchoring bolts of upper end, single footing.

The utility model is realized with the following method.

Steel building stone bolt locating template has the rectangle frame steel plate, is furnished with the bolt hole of wearing that matches with the stone bolt of upper end, concrete single footing on the edge of rectangle frame steel plate, and axis and the rectangle frame steel plate of wearing bolt hole are perpendicular.

Before the use, get two the utility model as upper and lower template, want to screw in upper and lower two nuts respectively on pre-buried one group of stone bolt, what the distance of the following and stone bolt of lower nut upper end was the pre-buried back stone bolt height that exposes upper surface, concrete single footing with steel plate thickness of the present utility model is poor, and the distance on the top and stone bolt of top nut is steel plate thickness of the present utility model and nut height sum.

During use, two parallel crossbeams are fixed in both sides in the position, upper surface of preparing making concrete single footing, top and the upper surface of preparing making concrete single footing of two parallel beams is on same plane, lower bolster is placed on two crossbeams of the position, upper surface of preparing making concrete single footing, the lower end of one group of stone bolt is inserted the bolt hole of wearing of lower bolster respectively, the upper end of this group stone bolt is inserted the bolt hole of wearing of cope match-plate pattern respectively, upper end at stone bolt screws in outer nut, cope match-plate pattern is fastened on the stone bolt with top nut and outer nut, use transit, level gauge, accurate invar tape, survey tools such as frame level and line bob are adjusted the horizontal level of this group stone bolt, morpheme such as absolute altitude and verticality parameter, make the morpheme parameter of stone bolt reach designing requirement, connect and be fastened on the cage of reinforcement of preparing making concrete single footing inserting stone bolt hypomere that lower bolster wears bolt hole method with spot welding, fluid concrete in template cavity that prepare to make the concrete single footing then, when concrete initial set, adjust the horizontal level of this group stone bolt more accurately with survey tool, morpheme such as absolute altitude and verticality parameter, make the morpheme parameter of stone bolt accurate, adhere to specification, after solidifying fully, concrete screws off nut, unload the utility model, then can obtain in concrete single footing upper end morpheme pre-embedded anchoring bolts accurately.

The utility model is simple in structure, easy to use, can make the accuracy of form and position of upper end, concrete single footing pre-embedded anchoring bolts higher.

Below in conjunction with accompanying drawing, the utility model is further described.
