Description

Maintenance bin upright column positioning construction method for PC component assembly line

Technical Field

The invention belongs to the technical field of PC component assembly line construction, and particularly relates to a maintenance bin upright post positioning construction method for a PC component assembly line.

Background

PC components, i.e. concrete pre-forms, are concrete component products produced by standardized, mechanized processes in factories. After the PC component is produced, the PC component is only required to be pulled to a construction site during use and hoisted to a floor needing to be assembled by hoisting equipment, and building construction can be completed like building blocks. In a factory, the PC component is produced in an annular assembly line mode, and the production processes comprise the processes of die table cleaning, line drawing, side die assembling, oil spraying, ferrying, material distributing, vibrating, surface leveling, maintaining, grinding, maintaining and demolding. The maintenance process of the PC component is maintained through a three-dimensional maintenance bin, and the standard allocation of the three-dimensional maintenance bin used by the invention is four-row eight-layer maintenance bins. After the four-row eight-layer curing bins are built, the front and rear bins have 60 upright posts, and the foundation bottom plate of each upright post is used for fixing 8 foundation bolts which have 480 foundation bolts; a top view of the foundation sole plate is shown with reference to fig. 1. Because stand quantity is very much, for guaranteeing maintenance storehouse installation accuracy, the installation requirement of stand includes: firstly, the ground levelness of each upright post is required to be within 2 mm; secondly, the central displacement degree of each upright post is within the range of 2 millimeters; and thirdly, the verticality of each upright post is within the range of 2 millimeters. In practical situations, each upright post is independently buried and then connected with each other through the transverse rib plates in the later period, so that the installation error rate of each upright post is extremely high, and the construction precision of the upright post in actual construction cannot meet the requirements at all. And because the construction precision of the stand column can not meet, the matching precision of the stand columns can not meet the production requirement. The existing method can only be compensated afterwards, namely after the foundation slab of the upright post is completely buried, the mounting hole of the foundation slab with deviation is artificially welded and cut to be large, namely the original straight hole-shaped mounting hole is transversely cut into a waist-shaped hole-shaped mounting hole, so that the function of online adjusting the position of the foundation slab is realized, and the mounting precision of the upright post is ensured. The later-period adjusting mode is time-consuming and labor-consuming, meanwhile, the installation cost is obviously increased, and the construction period is extremely delayed. Even sometimes, the construction error of the foundation slab is large enough, so that even if the edge of the foundation slab is cut by the mounting hole, the accuracy requirement of the installed stand column cannot be met, and the stand column must be reworked again, which obviously brings great trouble to actual constructors.

Disclosure of Invention

The invention aims to overcome the defects of the prior art and provides a maintenance bin upright positioning construction method for a PC component assembly line, which is simple and convenient to operate, has a low operation threshold, can effectively save labor, and can meet the requirement of upright construction precision through one-time construction.

In order to achieve the purpose, the invention adopts the following technical scheme:

a maintenance bin upright post positioning construction method for a PC component assembly line comprises the following steps:

s1), digging a foundation pit;

s2), embedding a reinforcing steel bar net rack in the foundation pit to form a foundation, and putting a pre-tied foundation reinforcing steel bar frame in a reserved pit of the foundation;

s3), buckling the working surface of the horizontally arranged positioning tool downwards on the foundation, enabling the mounting seats convexly arranged downwards on the working surface of the positioning tool to correspond to the foundation steel bar frames one by one, and fixedly connecting the corresponding mounting seats and the foundation steel bar frames in a threaded manner through foundation bolts; after the positioning tool and each foundation steel bar frame are fixed, adjusting the level and elevation of the positioning tool, and then fixing and positioning the positioning tool on the foundation;

the positioning tool is in a plane square frame shape, the bottom surface of the positioning tool forms the working surface, mounting seats are convexly arranged at the bottom surface corresponding to the mounting holes of the base bottom plate of the stand column, each mounting seat is in a flange structure, and assembling holes are arranged on the mounting seats in a penetrating mode; the positions of the assembly holes are in one-to-one correspondence with the corresponding mounting holes at the foundation slab of each upright post;

s4), performing first concrete pouring to fix the foundation reinforcing steel bar frame;

s5), after the concrete is solidified, removing all foundation bolts, and moving away the positioning tool, wherein all foundation steel bar frames are located at the designated positions;

s6), installing the foundation slab and the upright posts, and performing secondary concrete pouring on the root parts of the upright posts to fix the foundation slab.

Preferably, the positioning tool comprises two groups of subframes and a connecting frame for connecting the two groups of subframes; the sub-frame is a 'well' -shaped planar frame structure formed by five transverse rods and six longitudinal rods which are crisscrossed with each other, and each mounting seat is arranged at the crossed point of the transverse rods and the longitudinal rods; two sets of sub-frames are respectively arranged right above the foundation where the front cabin of the maintenance cabin is located and right above the foundation where the rear cabin is located, and the two sets of sub-frames are welded and fixed through connecting frames to form an integrated positioning tool.

Preferably, the assembly holes at each group of mounting seats are eight groups.

The invention has the beneficial effects that:

1) the invention solves the problem of extremely large installation error caused by the fact that the foundation steel bar frames are directly embedded in the foundation pit, constructs the reserved pit for placing the foundation steel bar frames in the foundation in advance by improving the construction scheme, and simultaneously realizes the function of positioning and assembling the foundation steel bar frames in the reserved pit one by taking the positioning tool as an external positioning piece. During actual construction, when the positioning tool is erected right above the foundation, due to the positioning function of the positioning tool, the positions of the foundation steel bar frames fixedly suspended at the positioning points of the positioning tool are accurately limited, and finally, the requirement of construction precision of the stand column can be met through one-time construction.

To sum up, through adopting above-mentioned scheme, rag bolt not only need not additionally to ligature pre-buried on basic steel reinforcement frame in the lump, and basic steel reinforcement frame location is accurate simultaneously, has also guaranteed the position accuracy nature of the foundation slab of later stage installation on basic steel reinforcement frame and even stand. Because stand position is accurate, a series of problems such as rag bolt need be adjusted and even foundation slab department mounting hole need additionally cut when also having removed traditional installation from, when practicing thrift artifically, the preparation degree of difficulty of maintenance storehouse further reduces, and whole construction flow is very simple and efficient.

2) The positioning tool is substantially a positioning tool. When the positioning tool is covered over the foundation, the mounting seats at the positioning tool form positioning points one by one, so that the function of positioning the mounting seats is realized. Once the foundation steel bar frames are fixedly suspended at the installation seats through bolts, the foundation steel bar frames are still positioned in the reserved pits and are accurately positioned and suspended by the positioning tool, and the subsequent pouring process effectively realizes the fixing operation of the foundation steel bar frames. To the quantity of the pilot hole of mount pad department to stable fixed basis reinforcing bar frame is for, also more than two sets of can. The assembly holes may cause the foundation reinforcing frame to be unstable in position under the action of external force such as cement impact force. Under the optimal condition, full matching, namely eight-assembly matching holes can be used, so that the foundation bolts are removed after the first cement pouring is finished, the matching holes in the foundation steel bar frame for matching the matching holes cannot be blocked by cement, and the purpose of reliable and quick fixing of the subsequent foundation base plate and the foundation steel bar frame is finally guaranteed.

In the above steps, compared with the construction process of the existing maintenance warehouse, the main changes are that the positioning tool 30 is added and the maintenance warehouse is changed from a manual mold access table to a manual mold access table.

Regarding the positioning tool 30, taking the standard configuration of the three-dimensional curing barn used in the present invention, i.e. four rows of eight-layer curing barn as an example, the front barn 40a has thirty-two groups of curing kilns with four rows and eight layers, and the rear barn 40b also has thirty-two groups of curing kilns with four rows and eight layers. The isolation between each layer of curing kilns can be ensured by a transverse supporting clapboard, and even the bottom support of the relative mould table can be simply formed by a supporting roller, and the curing kilns are completely communicated. At this time, the positioning tool 30 is shaped as shown in fig. 10, and includes two sets of subframes 31 and a connecting frame 32 for connecting the two sets of subframes 31. The sub-frame 31 is a "well" -shaped planar frame structure formed by five transverse rods and six longitudinal rods crisscrossed with each other, and each mounting seat 33 is arranged at the crossed point of the transverse rods and the longitudinal rods. The two sets of subframes 31 are respectively arranged right above the foundation where the front cabin 40a of the maintenance cabin is located and right above the foundation where the rear cabin 40b is located, and the two sets of subframes 31 are welded through the connecting frame 32 to form the integrated positioning tool 30. The bottom surface of the positioning tool 30 constitutes the working surface, and the bottom surface is provided with a mounting seat corresponding to the mounting hole of the foundation slab of the upright post 41 in a protruding manner. In actual operation, each mounting seat is of a flange structure, and eight assembling holes corresponding to the number of the foundation bolts at the foundation slab shown in fig. 1 are arranged on the mounting seats in a penetrating manner. The positions of the respective assembling holes are arranged in one-to-one correspondence with the corresponding assembling holes at the foundation slab of the respective columns 41 so that the respective foundation frames 20 can be fixed to the respective positioning-work mounting seats 33 by means of the anchor bolts, and the state shown in fig. 4 is established.

As shown in fig. 9 and 11 to 20, the mold stage access device 50 includes an access cart 51 having a rectangular cylindrical frame shape. The storing and taking vehicle 51 is placed on the cornice beam 43 at the opening of the front bin 40a through a platform and a guide wheel, so that the storing and taking vehicle 51 can move horizontally and transversely through the driving of a corresponding motor when needed. A horizontally disposed elevating platform 52 is disposed within the barrel cavity of the access cart 51, as shown with reference to fig. 11-12. In actual operation, as shown in fig. 11, the pulling motor 56a drives the pulling roller 56b to rotate, and then the pulling rope 56c is wound and unwound, so that the direction-changing wheels 56d and the steering wheels 56e change the direction of the pulling rope 56c, and the lifting control function of the lifting platform 52 is realized. The lifting platform 52 is in the shape of a square plate frame adapted to the shape of the barrel cavity of the access cart 51 so as to place the mold table. A set of push-pull assemblies 54, two sets of auxiliary roller assemblies 53 and a set of door opening mechanisms 55 are disposed at the front end and the rear end of the lifting platform 52, i.e., the left end and the right end shown in fig. 9. Wherein:

the push-pull piston cylinder 54a can be a push-pull cylinder or a push-pull cylinder, and the push-pull cylinder is preferably used on site in consideration of the weight of the die table and prefabricated parts on the die table. The cylinder wall of the push-pull piston cylinder 54a is horizontally hinged to the hinge base 54j, and the hinge base 54j and the slide rail base 54i are fixed to the frame of the lifting platform 52 as shown in fig. 11-13. The slide rail seat 54i has a rectangular groove shape, and the specific shape can be seen in fig. 15 and 17. A slide rail 54b is arranged in the groove cavity of the slide rail seat 54i along the groove length direction of the slide rail seat 54i, and a slide plate 54c is matched on the slide rail 54b in a guiding way. The slide 54c is parallel to the direction of movement of the slide 54b to be withdrawn from the die table to effect a material removal operation on the die table when the slide 54c is retracted.

The upper plate surface of the sliding plate 54c forms a mounting area of the rotating shaft 54 d; the purpose of simply supported beam-like swivel mounting of the spindle 54d is achieved by two sets of swivel supports 54g disposed at the two plate ends of the slide plate 54 c. And the lower plate surface of the slide plate 54c constitutes a mounting area of the rotary motor 54 e; the fixing function of the rotating electric machine 54e can be realized by the fixing base. The sliding plate 54c is provided with a passing hole through the plate body, the shaft body of the rotating shaft 54d is provided with a gear coaxially, the output shaft of the rotating motor 54e is provided with a chain wheel coaxially, and the chain wheel and the gear are connected through a chain to form the chain transmission mechanism.

In addition to the above configuration, the trailing end of the slide plate 54c is fixedly connected to the rod end of the push-pull piston cylinder 54a by a positioning pin or the like. As shown in fig. 15 to 20, a hook plate 54f in a square plate shape extending radially outward is provided at the front shaft end of the rotating shaft 54d, and a sector plate 54h at an angle of 90 ° as a stopper is disposed at the rear shaft end of the rotating shaft 54d, so that the purpose of the swinging motion of the hook plate 54f within a range of 90 ° is achieved. The sector plate 54h defines its swing position by a boss 54k, and the boss 54k can be realized by a screw with a nut shown in fig. 15, 1-18 and 20, which is screwed to the slide plate 54c, and the top end surface of the nut is the mating surface of the boss 54k opposite to the sector edge of the sector plate 54 h.

As for the auxiliary roller assemblies 53, the shape thereof is shown in fig. 11 and 13, each of the auxiliary roller assemblies 53 includes a set of power motors 53a and a set of rollers 53b coaxially fitted at the output shafts of the power motors 53 a. When the push-pull assembly 54 pushes the mold in place or pulls the mold in place, part of the bottom of the mold table is placed on the roller 53b, and then the mold table is moved to one direction of the lifting platform 52 or the curing kiln by the rotation of the power motor 53 a.

The specific construction of the door opening mechanism is shown in fig. 11-12 and includes a gantry mounted at the front and rear ends of the lift platform 52. The gantry is composed of two sets of vertically disposed vertical uprights 55a and a set of cross bars 55h erected at the top ends of the vertical uprights 55 a. In the structure shown in fig. 12, it can be seen that the door opening motor 55e is disposed on the cross rod 55h, and the two sets of screws 55f in the same direction on the cross rod 55h can be driven to rotate in the same direction by the action of the door opening motor 55e, so as to drive the driving sprocket 55d in the vertical upright rod 55a to move. The driving sprocket 55d drives the driven sprocket to move through the driving chain, and drives the door opening support block 55b fixedly connected to the driving chain to perform a vertical guiding movement relative to the lead of the notch of the vertical upright rod 55 a. The door opening support block 55b is matched with the through hole at the groove wall of the vertical upright rod 55a through the guide wheel 55c, so that the lifting action of the door opening support block 55b can be reliably ensured.

In order to further understand the present invention, the specific operation flow of the constructed curing barn of the present invention is described below with reference to fig. 9 and fig. 11-20:

in the normal use process of the curing barn, the lifting doors at the kiln mouths of the sixty-four curing kilns of the front barn 40a and the rear barn 40b of the curing barn are all in a descending closed state. At this time, the mold table is naturally cured in the curing kiln of the curing barn, and the whole curing barn is in the state shown in fig. 9.

When the mould table needs to be taken out from the front bin 40a or the rear bin 40b of the curing bin: the pulling motor 56a is started to lift the lifting platform 52 shown in fig. 11-13 to the height of the layer corresponding to the curing kiln of the curing barn to be stored. Then, the lifting platform 52 and even the access vehicle 51 are driven by the guide motor to move transversely until the door opening support block 55b is accurately positioned under the spigot lug of the lifting door at the kiln mouth of the curing kiln to be molded. Of course, the alignment of the spigot lugs can also be achieved by the opening bracket 55b itself by the drive sprocket or by tangential forward and backward motion along the driven sprocket. Then, the door opening motor 55e is started, the equidirectional screw rod 55f rotates to drive the driving chain wheel 55d and the driving chain to move, the door opening support block 55b moves upwards and drives the spigot lug to move upwards, and therefore the lifting door is lifted and moved upwards. Then, the push-pull unit 54 is activated, the push-pull piston cylinder 54a is activated, the slide plate 54c is pushed forward to the hooking position, and the push-pull piston cylinder 54a is stopped. Then, the rotating motor 54e is started to drive the hook plate 54f to rotate 90 degrees to stand, and the hook plate 54f is in a state shown in fig. 15-17, so that the die table is hooked from bottom to top. And then, the push-pull piston cylinder 54a is started to pull the sampling head, and the hook plate 54f at the sampling head and the die table form hooking matching, so that the die table can be pulled out of the curing kiln. After the sampling head is reset to the state shown in fig. 18-20, the mold stand is now just resting on the rollers 53b of the auxiliary roller assemblies 53. And starting the power motor 53a, and driving the roller 53b to rotate so as to drive the die table to completely slide into the lifting platform 52. And finally, the door opening motor 55e is started, the door opening support block 55b is driven reversely to move downwards to reset, and at the moment, the lifting door at the kiln opening of the current curing kiln slides downwards to reset under the action of gravity.

When the mould table needs to be stored in the front bin 40a or the rear bin 40b of the curing bin: the mold table is first placed at the lift platform 52 in advance. And then, starting the traction motor 56a, and lifting the lifting platform 52 to a high position corresponding to the curing kiln of the curing bin to be stored. Then, the lifting platform 52 and even the access vehicle 51 are driven by the guide motor to move transversely until the door opening support block 55b is accurately positioned under the spigot lug of the lifting door at the kiln mouth of the curing kiln to be molded. Of course, the alignment of the spigot lugs can also be achieved by the opening bracket 55b itself by the drive sprocket or by tangential forward and backward motion along the driven sprocket. Then, the door opening motor 55e is started, the equidirectional screw rod 55f rotates to drive the driving chain wheel 55d and the driving chain to move, the door opening support block 55b moves upwards and drives the spigot lug to move upwards, and therefore the lifting door is lifted and moved upwards. Then, the power motor 53a rotates to drive the roller 53b to move, so that the mold table is driven to horizontally move into the curing kiln. Then, the push-pull assembly 54 is started, and the rotating motor 54e rotates at this time, and transmits the force to the gear at the rotating shaft 54d through the connecting chain. The hook plate 54f is rotated by 90 ° to stand along with the rotation of the rotating shaft 54d, and the hook plate 54f is shown in fig. 15-17. Then, the push-pull piston cylinder 54a is started, the piston rod pushes the sliding plate 54c to move forward along the sliding rail 54b, and at this time, the hook plate 54f erected on the sliding plate 54c can be used as an extension arm of the lifting platform 52, so as to continuously push the mold platform to completely enter the curing kiln. Then, the rotating motor 54e rotates reversely to drive the rotating shaft 54d to rotate the hook plate 54f reversely by 90 ° and retract to the lodging position, at this time, the state of the hook plate 54f is as shown in fig. 18-20, and finally, the push-pull piston cylinder 54a is started to pull the sliding plate 54c back along the sliding rail 54 b. In actual operation, the fixed point positioning function of each mechanical action of the invention can be realized by combining the existing sensing component. If the grating sensor can be arranged at the kiln mouth of each curing kiln, if the grating is shielded when the component is stored for the last time, the grating is automatically stored to a higher layer of the front bin 40a or the rear bin 40b when the component is stored for the next time, so that the aim of automatic production of the invention is further perfected.
