Detailed description of the invention
Below in conjunction with accompanying drawing 1-3, a kind of embodiment of the present utility model is described.
For the positioning screw hole mould of pre-embedded bolt quick position, there is multiple bracing frame 1, described multiple bracing frame 1 is equipped with fixed mount 2, fixed mount 2 is L-type angle steel preferably, determine hole steel frame 4 to be longitudinally arranged on multiple fixed mount 2 upper surface and to determine hole steel frame 4 lower end and be provided with and multiplely determine hole steel plate 3, describedly determine hole steel plate 3 and be provided with multiple positioning screw hole 5, wherein, describedly determine hole steel frame 4 for U-type groove steel, describedly determine hole steel plate 3 and be rectangular steel plates and its corner is shaped with positioning screw hole 5 respectively.
In addition, as preferred version, support frame as described above 1 is provided with multiple row, often row are equipped with and determine hole steel frame 4, and the hole steel frame 4 of determining of adjacent column is connected to one by tie-beam; Describedly determine to be provided with reinforcement diagonal brace between hole steel frame 4 and tie-beam, between the bracing frame 1 of adjacent column, be also provided with reinforcement diagonal brace.
First be processed into monolithic bolt according to the spacing of bolt different in drawing and determine hole steel plate 3, positioning screw hole 5 (according to pre-embedded bolt specification determination pore size) is by special punch press punching, again according to basic distribution pattern, to hole steel plate 3 be determined and determine hole steel frame 4 and be welded to form monomer or hole steelframe determined by continuous print bolt, and can according to the basis of different size assembled formation respectively, it is reusable that hole steel plate 3 determined by one piece of bolt, easy accessibility.
First fix bracing frame 1 during use, after fixed mount 2 is shelved on bracing frame 1 ± 0.00 (herein based on absolute altitude top mark high+determine hole steel plate thickness) absolute altitude place is weldingly connected with it; Determine to check bolt absolute altitude after hole steel frame 4 is held on fixed mount 2, size is exposed according to drawing requirement bolt, to leak outside tightening nuts after size absolute altitude with nut adjustment, having checked bolt hole axial dimension subsequently can be weldingly connected determining hole steel frame 4 with fixed mount 2 and guarantees the axial dimension of bolt.
Determining hole steel plate 3 can adopt the thick general steel plate of 6-10mm to be cut into, and all positioning screw holes 5 adopt punch press to hole, and aperture requires only 1mm larger than pre-embedded bolt aperture, and deviation is not more than 0.2mm, and each aperture plane relative position deviation is within 1mm.Determining hole steel plate 3 ejects cross hairs to check Bolt sizes.
Determine hole steel frame 4 and can adopt the common channel-section steel of 5-8#, should select according to equipment Foundations Sizes, must guarantee its with determine hole steel plate 3 weld after resistance to overturning.
Fixed mount 2 can adopt the common channel-section steel of L30-L60, should select, must guarantee the resistance to overturning of its fixed support effect according to equipment Foundations Sizes.
Bracing frame 1 can adopt the common angle steel of L30-L60, should select, must guarantee the resistance to overturning of its fixed support effect according to equipment Foundations Sizes.
Installation and application:
A. building foundation bolt line and the releasing of template line on complete concrete bed course.
B. along four, electric hammer drill Φ 12 hole, basic both sides, require bed course to bore thoroughly, bore position can not affect equipment Foundations model sheetinstallat.
C. pound in hand-hole by long for 200mm Φ 10 round steel, requirement is pounded into rear round steel solid and reliable.
D. Φ 10 round steel and bracing frame 1 are welded, bracing frame 1 length is generally higher than basic more than end face 10cm; Because bracing frame cannot be fixed, do not advise that employing is pre-buried at foundation pad in advance, easily cause bracing frame waste of material, adopt the mode of fixing round steel to be connected with bracing frame 1, thus secure bracing frame 1; The object not affecting equipment Foundations model sheetinstallat is that after foundation construction, bracing frame 1 can take out secondary utilization, thus reaches the object of saving material.
E. with level gauge on bracing frame 1 will ± 0.000 (herein based on absolute altitude top mark high+determine hole steel plate 3 thickness) levelling line describes, then by being placed under fixed mount 2 (horizontal angle bar) ± 0.000 (herein based on absolute altitude top mark high+determine hole steel plate 3 thickness) levelling line welds with bracing frame 1.
F. be placed on determining hole steel frame 4 on fixed mount 2.
3, bolt absolute altitude is checked
A. be shelved on fixed mount 2 by determining hole steel frame 4;
B. pre-embedded bolt is arranged on and determines, on hole steel plate 3, to expose size according to drawing requirement bolt, to leak outside tightening nuts after size absolute altitude with nut adjustment.Monolithic after shelving determine hole steel plate 3 end absolute altitude namely based on end face ± 0.00 absolute altitude, only need determine bolt exposes size, layout design bolt exposed height=determine exerted bolt height on the steel plate 3 thickness+steel plate of hole.
C. bolt exposes after absolute altitude determines and double nut can be adopted to guarantee absolute altitude not by displacement during concrete placings.
4, pitch of bolts size is met
A. location-plate cross hairs is checked and basic cross hairs can guarantee pitch of bolts size with line pendant;
B. because determine each aperture plane relative position deviation of Bolt sizes of hole steel plate 3 within 1mm, only need have checked a set of two dimensional errors of determining hole steelframe 3 and just can control the whole series well and determine the bolt vertical displacement deviation of hole steelframe 3.
C. construct if any many row's same specification equipment Foundations simultaneously, after having checked Bolt sizes line, with channel-section steel, the hole steelframe 3 that is ranked is welded into framework entirety more, just can control the bolt horizontal movement deviation of hole steelframe 3 of being ranked more well.
The utility model is in the summary of experience of many Petroleum Casing Product Line foundation constructions, through meticulous optimal design, what guarantee bolt construction quality base completes, there is structure simple, cost is low, process is simple, repeatedly can have enough to meet the need recycling, speed of application is fast, bolt levels of precision after construction is high, and can effectively reduce the mass defects such as the displacement screw caused because of concreting, it is the inventive improvements to foundation built-in bolt jigs such as oil pipeline production lines, be applicable to metallurgy, chemical industry, the construction of the industry production line equipment Foundations such as machinery, economic and social benefit is remarkable.
