Abstract
The invention relates to an annular furnace base movable thread stand bolt positioning method. The method is implemented by arranging a total station at the central point of the annular base, putting the marked movable thread stand on a reinforcing steel bar fixing stand, moving the movable thread stand so that one straight line on the movable thread stand steel plate is in superposition with the straight line of the positioning bolt group, which passes through the central point of the annular base; the reinforcing steel bar fixing stand is marked; the total station is used for measuring the distance L from the central point of the annular base to central points of two mutually orthogonal straight lines on the movable thread stand, the difference value A between distance L and the radius R of the group of bolts is calculated, the position points of the group of bolts can be determined according to the difference value and marked on the reinforcing steel bar fixing stand to realize positioning the bolts. The method adopts the movable thread stand to mark on the reinforcing steel bar fixing stand, thus dispensing with quantities of steel plates or profile steel, being simple and fast, saving materials, and having precise positioning.
Description
Technical field
The present invention relates to the pre-embedded bolt localization method of a kind of industry, civilian ring foundation.
Background technology
Many groups pre-embedded bolt of annular distribution on the large-scale ring-like Equipment Foundations such as industry rotary heating furnace basis and the cold hole of sintered ring (the most nearly group surplus in the of 160) is the critical process of foundation construction, and its precision directly influences the next procedure installation quality.
Because bolt is distributed on the annulus, difficulty is bigger when measuring unwrapping wire.Traditional measurement unwrapping wire mounting method is: adopt §=4-6mm steel plate or 16a channel-section steel bolt frame plane as a whole, and unwrapping wire in the above, the boring erection bolt, every group of bolt needs one of the steel plate or [5.5 meters on the 12 channel-section steel bands of 1.2 meters * 1.2 meters of sizes.Adopt the method erection bolt operation many, high material consumption need be used square during unwrapping wire on steel plate, and precision is difficult for guaranteeing, influences the bolt installation quality.
Summary of the invention
The purpose of this invention is to provide a kind of annular furnace base movable thread stand bolt positioning method, this method adopts movable thread stand on the reinforcing bar fixed mount, to mark, and need not to use in a large number steel plate or shaped steel, and is simple and efficient, save material, accurate positioning.
For realizing above-mentioned purpose, the present invention adopts following technical scheme to realize:
A kind of annular furnace base movable thread stand bolt positioning method is characterized in that, this method comprises the steps:
1) make movable thread stand, its structure is the middle structural frame that can rule;
2) on the flat board of movable thread stand, draw two orthogonal lines, marked;
3) welded reinforcement fixed mount on the good steel mesh reinforcement of colligation is as the usefulness of measuring cultellation;
4) at the ring foundation central point total powerstation is set, the movable thread stand of marked is placed on the reinforcing bar fixed mount, move movable thread stand, the straight line on the movable thread stand steel plate is overlapped with the straight line that passes through the ring foundation central point of positioning bolt group; And on the reinforcing bar fixed mount, perform mark;
5) measure the distance L of ring foundation central point two mutual vertical line central points on the movable thread stand with total powerstation; Calculate the difference A of distance L and this group bolt radius R of living in; Can determine each location point of this group bolt according to difference; On the reinforcing bar fixed mount, perform mark, promptly realized the location of bolt.
Compared with prior art, the invention has the beneficial effects as follows:
1) cancels steel plate or shaped steel as the bolt mounting and fixing support, fundamentally solved the problem of high material consumption;
2) reduce working procedure, reduced engineering cost, saved the operation that making, installation steel plate or shaped steel fixed mount, unwrapping wire are holed;
3) improved the bolt installation accuracy.

The difference of the distance L of A-annular furnace central point two vertical line intersection points on the movable thread stand and this group bolt radius R of living in
The specific embodiment
Further specify the present invention through specific embodiment below.
This embodiment is an application example in φ 177 petroleum pipeline engineering annular furnace bases.
1, equipment, material are prepared:
A. welding equipment: one of electric welding machine.
B. ∠ 50 * 5 angle steel, §=6mm steel plate, φ 20 indented barss.
C. total powerstation is one.
2, movable thread stand is made:
A. adopt the frame of ∠ 50 * 5 angle steel weldering system 800 * 600, middle steel plate and angle frame firm welding with 6mm thick 600 * 400.
B. make two mutually perpendicular lines in the steel plate center, and marked.
3, reinforcing bar fixed mount welding: the continuous fixed mount of welded closure on the good steel mesh reinforcement of colligation, as the usefulness of measuring cultellation, fixed mount should be stablized firmly.
4, total powerstation range finding cultellation:
A. at the good total powerstation of ring-like base center point frame, on the reinforcing bar fixed mount, move movable thread stand, make straight line and the straight line that passes through the ring foundation central point of positioning bolt group on the movable thread stand steel plate heavily be incorporated in marked on the reinforcing bar fixed mount.
B. record the distance L of annular furnace central point two vertical line intersection points on the movable thread stand with total powerstation, calculate the difference A of L and this group bolt radius R of living in, can confirm the location point of this group bolt according to difference A, and on the reinforcing bar fixed mount marked.
5, bolt is installed: move movable thread stand out, and measure installation absolute altitude, erection bolt.
6, bolt accuracy checking:, carry out national current standard with chi and level gauge inspection bolt level and vertical missing.
