Description

Technical Field

[0001] The utility model belongs to the technical field of pile foundation construction, and in particular relates to a universal structure that combines a guiding steel casing with a hanging steel bar cage. Background Art

[0002] During the pile foundation construction process, it is necessary to first construct a positioning guide frame, then insert the guide steel casing, and then lift the cylindrical steel cage into the steel casing. Due to the structural strength requirements, the steel casing must be set concentrically with the steel cage. Therefore, this requires that during the process of lifting the steel cage behind the steel casing, the positioning of the steel cage must be guaranteed at all times.

[0003] To this end, the general means is to respectively set up a guide frame structure for guiding the steel casing and a wellhead frame structure for hanging the steel cage at the target location and carry out construction. The functions of these two structures are relatively simple. When the process is converted, the corresponding structures need to be made on site, which brings inconvenience to the construction, affects the construction period, and increases the project cost. For this reason, a general solution, such as a guide platform for assisting the positioning of the above-water steel casing and the fixing of the steel cage disclosed in CN219175237U, includes a main span frame in the shape of a square frame, diagonal braces arranged at four corners in the main span frame, and positioning pins arranged on the diagonal braces at a predetermined height and slidable on the diagonal of the main frame, the positioning pins are used to insert into the hanger rod holes on the hanger rods and adjust the position of the steel cage and position it. The guide platform for assisting the positioning of the steel casing on water and fixing the steel cage provided by the utility model utilizes a slidable positioning pin to dock with the hanging rod holes on the hanging rod, so that the four hanging rods are on four positioning pins at the same height, thereby ensuring that the steel cage suspended by the four hanging rods will not tilt, thereby positioning the steel cage suspended by the hanging rods. In the above structure, although it simultaneously realizes the auxiliary positioning of the steel casing and the auxiliary positioning of the steel cage, it fails to promptly remind the operating personnel when it tilts itself, and thus cannot eliminate the phenomenon of the entire structure tilting. For this reason, a universal structure that has its own horizontality measurement capability and accurate positioning, and takes into account both guiding the steel casing and hanging the steel cage, is needed.

[0020] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the specific implementation method, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0021] See also Figure 1-3 A universal structure for guiding steel casing and hanging steel cage, comprising two transverse rods 1 and two longitudinal rods 2, wherein the two transverse rods 1 and the two longitudinal rods 2 form a square frame structure, wherein four diagonal braces 3 are respectively arranged at the four inner corners of the square frame structure, and latches 4 are slidably arranged in the four diagonal braces 3;

[0022] Specifically, the transverse member 1 is a member in the transverse direction of the bridge, and its specification is a steel section of HW350×350×6000. The longitudinal member 2 is a member in the vertical direction of the bridge, and its specification is a steel section of HW350×350×3710. The two transverse members 1 and the two longitudinal members 2 respectively constitute the two lengths and two widths of the frame structure. At this time, the frame structure constitutes four right-angled inner corners. Each diagonal brace 3 is formed by welding two steel sections with specifications of HW350×350×1763 in parallel. The two ends of the diagonal brace 3 are respectively connected to a transverse member 1 and a longitudinal member 2. At this time, each diagonal brace 3 covers an inner corner of the frame structure. A hole is opened in each diagonal brace 3, and a latch 4 is opened in each hole. The position of the opening ensures that the four latches 4 are in the same horizontal plane, and the horizontal plane is parallel to the frame structure.

[0023] When in use, during the process of lowering the steel casing 6, the latch 4 is moved back so that the passable area in the frame structure is maximized, so as to facilitate the steel casing 6 to smoothly pass through the hole of the frame structure. Subsequently, the steel casing 6 is welded to the diagonal brace 3 through a steel plate, and then a new section of the steel casing 6 is hoisted by a gantry crane. After the welding of the ends of the two sections of the steel casing 6 is completed, the guidance of the steel casing 6 by this structure is completed;

[0024] Subsequently, the lowered steel casing 6 is hoisted by a gantry crane, and the connection between the steel casing 6 and the diagonal brace 3 is cut to facilitate the use of the universal structure in subsequent processes. Subsequently, the gantry crane slowly lowers the steel casing 6 into place, and performs the process of lowering the steel cage 7;

[0025] When used for hanging the steel cage 7, first use the movable latch 4 to clamp the steel cage 7 lowered into the steel casing 6. Due to the position of the opening, the four latches 4 are guaranteed to be in the same horizontal plane, and the horizontal plane is parallel to the frame structure. That is, after the latch 4 clamps the steel cage 7, the steel cage 7 can be guaranteed to be parallel to the surface where the four latches 4 are located, and at the same time parallel to the frame structure, ensuring that the steel cage 7 in the steel casing 6 is parallel to the steel casing 6. At the same time, since the diameter of the steel cage 7 is smaller than the steel casing 6, when the latch 4 clamps the steel cage 7, the part of the latch 4 located on the outside of the steel cage 7 will inevitably abut against the upper edge of the steel casing 6. At this time, the four latches 4 ensure that they are in the same horizontal plane with the upper edge of the steel casing 6, and ensure that the steel cage 7 is in the same horizontal plane with themselves, thereby ensuring that the steel cage 7 and the upper edge of the steel casing 6 are in the same horizontal plane, completing the positioning of the steel cage 7;

[0026] During the subsequent hanging and installation process of the steel cage 7, a new section of the steel cage 7 is welded on top of the stuck steel cage 7 to complete the height connection of the steel cage 7. Subsequently, the latch 4 is pulled away from the steel cage 7 until the latch 4 no longer clamps the steel cage 7. At this time, the crane is used to lower the connected steel cage 7 to the target position. After the steel cage 7 reaches the target position, the latch 4 is pulled toward a position close to the steel cage 7 until the latch 4 clamps the steel cage 7 again, thereby completing the auxiliary positioning of the steel cage 7 for hanging and placing by this structure.

[0027] By arranging the diagonal brace 3 in the frame structure and arranging the telescopic sliding pin 4 in the diagonal brace 3, the present structure can guide the steel casing 6 and assist in hanging the steel cage 7.

[0028] In the above structure, there is a probability that the steel casing 6 or the steel cage 7 itself is not perpendicular to the ground. At this time, even if the general structure is in contact with the steel casing 6, it will not be able to complete the guidance correctly. In order to promptly remind the operating personnel when it tilts, the four diagonal braces 3 are respectively provided with a strip level, and the axial direction of the strip level is parallel to the diagonal brace 3. Specifically, since the four diagonal braces 3 are all composed of steel sections, the axis line of the strip level is parallel to the long side of the corresponding diagonal brace 3 steel section. At this time, the mechanism itself can measure the horizontality in two directions.

[0029] By arranging bar-type level gauges on the four diagonal supports 3 respectively, the mechanism itself can measure the horizontality in two directions, and promptly remind the operator when the mechanism itself tilts, thereby improving the positioning accuracy.

[0030] In the above process, in addition to the tilting of the structure itself, there is still a probability that the pin 4 will be twisted or pried during the sliding process in the open hole. At this time, the pin 4 cannot ensure that it is parallel to the frame structure. In order to promptly remind the operator when the pin 4 is twisted or pried, any pin 4 is suspended with a verticality detector. The verticality detector will sound an alarm when the angle between the pin 4 and the ground is 0 to 85 degrees. Specifically, the verticality detector includes a plumb bob and a hollow cylinder sleeved around the plumb line. The inner wall of the cylinder is sleeved with a trigger alarm. Under normal conditions, the plumb bob does not collide with the cylinder. When the pin 4 is not parallel to the ground, it drives the cylinder to tilt, and the plumb bob is still perpendicular to the ground. At this time, the plumb bob collides with the cylinder, triggering the trigger alarm to complete the reminder to the operator.

[0031] By suspending a verticality detector on any of the latch pins 4, a reminder is issued to the operator when the latch pin 4 deviates from a state horizontal to the ground.

[0032] Specifically, the latch 4 is an I-beam of 40b×880;

[0033] At the same time, in order to ensure that a strip structure with a strip cross-section is formed at one end of the pin 4, specifically, the flanges on both sides of one end of the pin 4 are completely cut. At this time, the cross-sectional area of ​​the end of the pin 4 close to the steel cage 7 is smaller and is strip-shaped, which is convenient for inserting into the steel cage 7 and preventing the situation where the steel cage 7 cannot be positioned.

[0034] In order to improve the support strength of the latch 4, alternatively, a latch door frame 5 is provided in each of the four diagonal braces 3, and the latch 4 is slidably provided in the latch door frame 5. The latch door frame 5 is formed by welding and fixing three groups of I-beams, and the specifications are respectively two groups of I-beams 25b×300 and one group of I-beams 25b×700. After welding, a rectangular hole is formed in the latch door frame 5, and the rectangular hole is used to accommodate the latch 4 and allow the latch 4 to slide therein;

[0035] At the same time, a lock is provided in the latch door frame 5, and the lock is used to lock or unlock the latch 4. Specifically, the lock is arranged above the rectangular hole, and when locking, the latch 4 below is pressed to prevent the latch 4 from moving to complete locking, or the lock is moved away from the latch 4 below to complete unlocking.

[0036] In order to improve the structural strength of the frame structure, a stiffening plate is arranged on the outside of any transverse rod 1 and longitudinal rod 2, and the stiffening plate is arranged parallel to the corresponding transverse rod 1 or vertical rod.

[0037] The working principle and use process of this utility model:

[0038] When in use, during the process of lowering the steel casing 6, the latch 4 is moved back so that the passable area in the frame structure is maximized, so as to facilitate the steel casing 6 to smoothly pass through the hole of the frame structure. Subsequently, the steel casing 6 is welded to the diagonal brace 3 through a steel plate, and then a new section of the steel casing 6 is hoisted by a gantry crane. After the welding of the ends of the two sections of the steel casing 6 is completed, the guidance of the steel casing 6 by this structure is completed;

[0039] Subsequently, the lowered steel casing 6 is hoisted by a gantry crane, and the connection between the steel casing 6 and the diagonal brace 3 is cut to facilitate the subsequent use of the structure. Subsequently, the gantry crane slowly lowers the steel casing 6 into place, and the process of the steel cage 7 below is carried out;

[0040] When lowering the steel cage 7, first use the movable pin 4 to clamp the steel cage 7 lowered into place, and then lower the steel cage 7 together with the present structure into the steel casing 6. The position of the opening ensures that the four pins 4 are in the same horizontal plane, and the horizontal plane is parallel to the frame structure. That is, when the pin 4 clamps the steel cage 7, the steel cage 7 can be guaranteed to be parallel to the surface where the four pins 4 are located, and at the same time parallel to the frame structure. At the same time, since the diameter of the steel cage 7 is smaller than the steel casing 6, when the pin 4 clamps the steel cage 7, as it is lowered, the part of the pin 4 located on the outside of the steel cage 7 will inevitably abut against the upper edge of the steel casing 6. At this time, the four pins 4 ensure that they are in the same horizontal plane with the upper edge of the steel casing 6, and ensure that the steel cage 7 is in the same horizontal plane with themselves, thereby ensuring that the steel cage 7 and the upper edge of the steel casing 6 are in the same horizontal plane, thereby completing the positioning of the steel cage 7.
