Description

Technical Field

[0001] The invention belongs to the technical field related to civil engineering, and in particular relates to a steel bar length connecting device for civil engineering and a use method thereof. Background Art

[0002] Civil engineering refers to the various technical works such as survey, planning, design, construction, installation and maintenance for the construction, reconstruction or expansion of buildings, structures and related supporting facilities of various projects, in addition to housing construction, and the completed engineering entities. Civil engineering also refers to the object of engineering construction, that is, various engineering facilities built on the ground or underground, on land or in water, which directly or indirectly serve human life, production, military and scientific research. Due to the addition of steel bars, the bearing capacity and deformation capacity of the building are improved. Therefore, a large number of steel bar structures will be used in civil engineering buildings, but the lengths of steel bars used in various engineering equipment are different. According to the existing public document CN212104826U, in order to be able to use the steel bar length required by the engineering equipment, it is necessary to use the corresponding length connection device to connect the steel bars.

[0003] However, when the length of the steel bar is connected, the two steel bars are connected by mechanical connection. Most of the connection methods use mechanical parts such as sleeves and threads to apply pressure to the steel bar at the joint, and the friction of the inner wall or the bite force of the thread is used to achieve effective connection of the steel bar. However, this connection method causes wear between the structure and the steel bar, and the end of the steel bar needs to be processed into a threaded shape, so the steel bar cannot be directly connected. When the assembly structure is used to position the cross ribs on the surface wall of the steel bar, this connection method requires the steel bar to slide along the inside of the sleeve. However, during this movement, since there is no positioning processing for the sliding direction of the steel bar, the steel bar is easy to move out of position, resulting in the assembly structure and the cross ribs on the surface wall of the steel bar being offset, making it impossible for the assembly structure to accurately and stably assemble and position the steel bar. To this end, we provide a steel bar length connection device and a method of use for civil engineering to solve the above problems. Summary of the invention

[0009] The present invention is further configured such that a plurality of limiting holes evenly distributed along the circumferential direction are formed on the end surface of the abutting ring relative to the limiting ring, and limiting rods are fixed at positions of the movable ring corresponding to the limiting holes.

[0010] The present invention is further configured such that the end faces of the limiting ring corresponding to the abutting ring are provided with plugging holes corresponding to the limiting holes one by one, and the ends of the limiting rods passing through the plugging holes are respectively plugged into the corresponding limiting holes.

[0011] The present invention is further configured such that an annular tooth groove is provided inside the annular groove near the end face of the abutment ring, a tooth ring meshing with the annular tooth groove is fixed to the end face of the movable ring near the abutment ring, and an extrusion spring abutting against the inner end face of the annular groove is fixed to the other end face of the movable ring.

[0012] The present invention is further configured such that two parallel transverse holes are provided inside the opposite ends of the two sleeves, and the middle positions of the transverse holes are respectively connected to the interiors of the adjacent stamping holes, and long curved holes and short curved holes are respectively provided at both ends of each transverse hole inside each sleeve, and the long curved holes and short curved holes provided in the same direction of each transverse hole are connected to the interior of the same adjacent strip opening, the linkage blocks located in the direction of the interior of the sleeve are fixed with short curved rods passing through the short curved holes, and the linkage blocks located in the direction of the sleeve port are fixed with long curved rods passing through the long curved holes.

[0013] The present invention is further configured such that piston blocks are fixed to the end faces of the short curved rod and the long curved rod inside the transverse hole, and return springs abutting against the inner end faces of the transverse hole are fixed to the opposite end faces of the two piston blocks inside each transverse hole.

[0015] The present invention also provides a method for using a steel bar length splicing device for civil engineering, which is used by the following steps:

[0016] S1: insert two steel bars into corresponding sleeves respectively, and control the position of the steel bar transverse ribs to align with the position of the clamping block, and control the radial gap between the steel bar transverse ribs to align with the position of the linkage block;

[0017] S2: After the steel bar moves inside the sleeve, it will gradually squeeze the pushing plate after it contacts the pushing plate, so that the pushing plate controls the piston rod to move out of the strip opening through the air pressure control linkage block and contact the smooth surface of the steel bar surface wall;

[0018] S3: When the steel bar moves and deviates inside the sleeve, causing the steel bar to tilt with the inside of the sleeve, the tilted part of the steel bar will push the linkage block abutting against it, and then another linkage block used in conjunction with the linkage block will push the steel bar to reset its tilted direction, pushing the steel bar through two points in opposite directions, so as to correct the steel bar;

[0020] The present invention has the following beneficial effects:

[0021] When the two sleeves are moved relative to each other for assembly, the abutment ring and the limit ring between the two sleeves move relative to each other, and then the abutment ring and the limit ring respectively push the clamping blocks used in conjunction with them to move out of the recesses, and the arc rods at the opposite end faces of the two clamping blocks are directly located between two adjacent transverse ribs on the surface of the steel bar. The transverse ribs and the arc rods are staggered and limited, so the steel bar cannot move laterally inside the sleeve, thereby realizing the connection of the two steel bars. At the same time, the limit ring and the abutment ring are positioned by the limit rod so that the two will not rotate in an interlaced manner, thereby preventing the two sleeves from detaching and improving the stability of the connection of the two steel bars.

[0022] The linkage block inside each strip opening is controlled to directly contact the transverse smooth surface of the steel bar surface wall. When the steel bar is tilted inside the sleeve, the two transverse cross rib surfaces of the two steel bars are limited by the two clamping blocks. Then, the transverse smooth surface of the steel bar is pushed in a linkage manner through the linkage block. When the steel bar tilts on one side, the linkage block connected to the inclined part will drive the linkage block on the other side to push the steel bar, thereby realizing the calibration of the steel bar and ensuring the stability of the steel bar connection process.

[0023] Of course, any product implementing the present invention does not necessarily need to achieve all of the above advantages at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0038] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Example 1

[0039] See also Figure 1 , Figure 2 , Figure 3 , Figure 5 and Figure 8, which is the first embodiment of the present invention, provides a steel bar length connection device for civil engineering, wherein the two sleeves 101 are anti-rotationally treated by the use of a limit ring 402 and an abutment ring 401, and the clamping block 201 and the slide rod 202 stably assemble the steel bar in the sleeve 101, thereby achieving stable connection of the two steel bars, and at the same time, multiple linkage blocks 501 cooperate to abut against the transverse smooth surface of the steel bar, so that the steel bar can be corrected during the movement process to ensure stable movement.

[0040] Specifically, the assembly component 100 includes two sleeves 101 that are symmetrical and oppositely disposed at the ports, the positioning clamping component 200 includes a clamping block 201 located at an inner position of each notch 101b, the pushing component 300 includes a pushing plate 301 located at an inner position of each sleeve 101, the limiting component 400 includes an abutting ring 401 and a limiting ring 402 located at the positions of the two sleeves 101, and the linkage correction component 500 includes two symmetrically disposed linkage blocks 501 located at the position of each strip-shaped port 101a;

[0041] Through the arrangement and use of the above-mentioned structure, the two steel bars are respectively inserted into the corresponding sleeves 101, and the pushing assembly 300 is gradually pushed by the steel bars to control the linkage block 501 on the linkage correction assembly 500 to connect with the surface wall of the steel bars. Therefore, when the steel bars are displaced during the gradual movement, the linkage block 501 will be pushed, and the two linkage blocks 501 used in conjunction with the same transverse hole 101c are in linkage work, so the two linkage blocks 501 used in conjunction will push the steel bars, so that the steel bars can remain stable during the movement.

[0042] according to Figure 3 , Figure 4 , Figure 7 , Fig. 9 and Fig.10 , the inner wall of each sleeve 101 is provided with two strip openings 101a uniformly distributed along the circumferential direction, the inner wall of the sleeve 101 located between the two strip openings 101a is provided with a notch 101b, the opposite surfaces of the two clamping blocks 201 inside each sleeve 101 are fixed with a plurality of uniformly distributed arc rods 201a, the axial position of the inner end surface of each sleeve 101 is fixed with a cylinder 102, the end surface of the cylinder 102 is provided with two symmetrically arranged punching holes 102a, the end surface of the pushing plate 301 is fixed with two piston rods 303 respectively inserted into the inner position of the punching holes 102a, the inner surface of the limiting ring 402 is provided with an annular groove 402a connected with the outside, the part of the annular groove 402a close to the abutting ring 401 is sleeved with a movable ring 403, and the linkage block 501 is located at the transverse smooth surface position between the steel bar transverse ribs inside each sleeve 101;

[0043] When the above-mentioned structure is used, when the two sleeves 101 are relatively moved and assembled, the abutment ring 401 and the limiting ring 402 between the two sleeves 101 move relatively, and then the abutment ring 401 and the limiting ring 402 respectively push the clamping block 201 used therewith to move out of the recess 101b, and the arc rods 201a at the opposite end faces of the two clamping blocks 201 are directly located between two adjacent transverse ribs on the surface side of the steel bar, and the steel bar cannot move laterally inside the sleeve 101 through the staggered limiting between the transverse ribs and the arc rods 201a, thereby realizing the continuous connection of the two steel bars;

[0044] At the same time, when the steel bar moves inside the sleeve 101 and pushes the pushing plate 301, the pushing plate 301 will drive the piston rod 303 to move inside the punching hole 102a, and thereby compress the internal gas of the punching hole 102a, thereby controlling the linkage block 501 inside each strip opening 101a to directly abut against the transverse smooth surface of the steel bar surface wall, and then when the steel bar is located inside the sleeve 101 and tilts, the two clamping blocks 201 limit the transverse cross rib surfaces of the two steel bars, and then the linkage block 501 is used to push the transverse smooth surface of the steel bar in a linkage manner, so that when the steel bar tilts on one side, the linkage block 501 connected to the inclined part will drive the linkage block 501 on the other side to push the steel bar, thereby realizing the calibration of the steel bar and ensuring the stability of the steel bar connection process.

[0045] Further, according to Figure 2 , Figure 4 , Figure 5 , Figure 7It can be seen that the end surface of the pushing plate 301 opposite to the end of the sleeve 101 is fixed with a pushing spring 304, and the other end of the pushing spring 304 is fixed with a mounting ring 302 bolted to the inner end surface of the sleeve 101. When the pushing plate 301 is compressed by the steel bar, the pushing plate 301 will compress the pushing spring 304, and when the steel bar is not in the sleeve 101, the pushing spring 304 will push the pushing plate 301 to make the pushing plate 301 stable in the sleeve 101. A stud 105 is fixed to the end surface of one sleeve 101, and an inner screw barrel 104 spirally connected to the stud 105 is fixed to the end surface of the other sleeve 101. The abutment ring 401 is set The limiting ring 402 is sleeved on the inner screw barrel 104 and connected to the end face of the inner screw barrel 104 on the stud 105. Since the limiting ring 402 is sleeved on the inner screw barrel 104 and the abutting ring 401 is sleeved on the stud 105, the limiting ring 402 can move along the inner screw barrel 104 and the abutting ring 401 can move along the stud 105. Moreover, since the abutting ring 401 and the limiting ring 402 are respectively fixedly connected to the adjacent sliding rod 202, it can be ensured that the abutting ring 401 and the limiting ring 402 can no longer rotate with the stud 105 and the inner screw barrel 104, and then when the stud 105 and the inner screw barrel 104 are spirally assembled, the abutting ring 401 and the limiting ring 402 will abut against each other.

[0046] It should be noted that the sliding rod 202, short curved rod 502 and long curved rod 504 used are all set to soft materials, so the sliding rod 202 in the sliding hole 101b-1, the short curved rod 502 in the short curved hole 101a-2 and the long curved rod 504 in the long curved rod 504 can bend and move, thereby driving the linkage block 501 and the clamping block 201 connected thereto to follow the movement. Example 2

[0047] See also Figure 3 , Figure 8 and Fig. 9 On the basis of Example 1, in this embodiment, the round rod 203 can slide along the inside of the cylinder 103, and the round rod 203 is assembled and connected with the clamping block 201, so the round rod 203 will limit the clamping block 201 to ensure that the clamping block 201 can stably extend and retract in the recess 101b.

[0048] Specifically, the opposite end faces of the two sleeves 101 are provided with two sliding holes 101b-1 respectively connected to the inside of the recess 101b, and the end face of each clamping block 201 is fixed with a sliding rod 202 that matches the clearance of the sliding hole 101b-1. The end face of the sliding rod 202 passing through the inner end of the sliding hole 101b-1 is fixedly connected to the end face of the adjacent abutment ring 401 or the end face of the limiting ring 402. The outer wall of each sleeve 101 is fixed with multiple cylinders 103 respectively connected to the inside of the adjacent recess 101b, and the end face of the clamping block 201 is fixed with round rods 203 respectively inserted into the internal position of the cylinder 103.

[0049] By using the above structure, when the abutment ring 401 and the limiting ring 402 are connected and pushed against each other, the slide rod 202 is pushed to slide in the inner position of the slide hole 101b-1, and the clamping block 201 is pushed out of the notch 101b, so that the clamping block 201 is in contact with the surface of the steel bar, and the clamping block 201 drives the round rod 203 to slide inside the cylinder 103, and the cylinder 103 limits the round rod 203, so that the round rod 203 can only move along the cylinder 101b. 3, so that the clamping block 201 can be extended and retracted inside the notch 101b. After the two sleeves 101 are separated from each other, the abutting ring 401 and the limiting ring 402 can be moved away from the sleeve 101, and then the abutting ring 401 and the limiting ring 402 will drive the sliding rod 202 to be drawn out from the sliding hole 101b-1, and the sliding rod 202 will drive the clamping block 201 to move into the notch 101b, so that the clamping block 201 and the steel bar are separated from the abutting relationship. Example 3

[0050] See also Figure 8 , Fig. 9 , Fig.10 and Fig.11 On the basis of Example 1, this embodiment drives the limiting rod 403a to be inserted from the plug hole 402b to the position in the corresponding limiting hole 401a through the movable ring 403, and then limits the abutment ring 401 and the limiting ring 402, so that the limiting ring 402 and the abutment ring 401 cannot rotate alternately, thereby improving the stability of the assembly of the two sleeves 101.

[0051] Specifically, a plurality of limiting holes 401a uniformly distributed along the circumferential direction are provided on the end surface of the abutting ring 401 relative to the limiting ring 402, limiting rods 403a are fixed at the positions of the movable ring 403 corresponding to the limiting holes 401a, and the end surface of the limiting ring 402 corresponding to the abutting ring 401 is provided with plugging holes 402b corresponding to the limiting holes 401a one by one, and the ends of the limiting rods 403a passing through the plugging holes 402b are respectively plugged into the corresponding limiting holes 401a, and an annular tooth groove 402c is provided on the end surface of the annular groove 402a close to the abutting ring 401, and a tooth ring 403b meshing with the annular tooth groove 402c is fixed on the end surface of the movable ring 403 close to the abutting ring 401, and an extrusion spring 403c abutting against the inner end surface of the annular groove 402a is fixed on the other end surface of the movable ring 403;

[0052] By setting and using the above structure, after the inner screw barrel 104 is screwed on the stud 105, the rotation of the inner screw barrel 104 will drive the limiting ring 402 to rotate accordingly. Therefore, after the limiting ring 402 is connected with the abutting ring 401, the inner screw barrel 104 is controlled to rotate. Under the condition of ensuring that the clamping block 201 is connected with the steel bar, the plug hole 402b on the end face of the limiting ring 402 corresponds to the limiting hole 401a on the end face of the abutting ring 401. Then, when the movable ring 403 is released, the extrusion spring 403c at this time will push the movable ring 403 to move in the direction of the plug hole 402b, and control the rotation of the movable ring 403, so that the limiting rod 401 on the end face of the movable ring 403 is 03a is aligned with the position of the plug hole 402b, so that the limiting rod 403a passes through the position of the plug hole 402b and is inserted into the limiting hole 401a, and the abutting ring 401 and the limiting ring 402 are assembled through the limiting rod 403a, so that the abutting ring 401 and the limiting ring 402 will not rotate relative to each other, and after the movable ring 403 is pushed, the gear ring 403b will be inserted into the annular tooth groove 402c, and at the same time, the limiting ring 402 and the sleeve 101 are assembled through the sliding rod 202, so that the two sleeves 101 cannot rotate relative to each other, ensuring the stable assembly of the inner screw barrel 104 and the stud 105, so that the inner screw barrel 104 and the stud 105 will not be easily separated;

[0053] When it is necessary to control the rotation of the inner screw barrel 104, the movable ring 403 can be controlled to move along the opening position of the annular groove 402a. When the movable ring 403 compresses the extrusion spring 403c, the movable ring 403 will also drive the limiting rod 403a to disengage from the limiting hole 401a and the plug-in hole 402b. At the same time, the movable ring 403 will also drive the gear ring 403b to disengage from the annular gear groove 402c. At this time, the limiting ring 402 and the abutting ring 401 can be controlled to rotate alternately. Example 4

[0054] See also Figure 3 , Figure 4 and Figure 6 On the basis of Example 1, this embodiment has the piston block 503 inside each transverse hole 101c fixedly connected to the long curved hole 101a-1 and the short curved hole 101a-2 respectively, so that when a single piston block 503 slides inside the transverse hole 101c, it will control the other piston block 503 to follow the movement, thereby realizing the coordinated work of the two linkage blocks 501.

[0055] Specifically, two parallel transverse holes 101c are provided inside the opposite ends of the two sleeves 101, and the middle positions of the transverse holes 101c are respectively connected to the inside of the adjacent punching holes 102a, and the two ends of each transverse hole 101c inside each sleeve 101 are respectively provided with a long curved hole 101a-1 and a short curved hole 101a-2, and the long curved hole 101a-1 and the short curved hole 101a-2 arranged in the same direction of each transverse hole 101c are both connected to the inside of the same adjacent strip opening 101a. The linkage blocks 501 located in the inner direction of the sleeve 101 are all fixed with short curved rods 502 passing through the short curved holes 101a-2, and the linkage blocks 501 located in the end direction of the sleeve 101 are all fixed with long curved rods 504 passing through the long curved holes 101a-1. The end surfaces of the short curved rods 502 and the long curved rods 504 inside the transverse holes 101c are all fixed with piston blocks 503, and the opposite end surfaces of the two piston blocks 503 inside each transverse hole 101c are all fixed with return springs 503a abutting against the inner end surface of the transverse hole 101c.

[0056] By setting and using the above structure, when the pushing plate 301 is pushed by the steel bar, the pushing plate 301 will compress the inside of the punching hole 102a through the piston rod 303. Since the punching hole 102a is connected to the inside of the transverse hole 101c, the gas inside the transverse hole 101c will be compressed, and the two movable blocks inside each transverse hole 101c will be controlled to move in opposite directions, thereby pushing the long curved rod 504 to slide in the long curved hole 101a-1 and pushing the short curved rod 502 to move in the short curved hole 101a-2. At this time, the piston block 503 will compress the return spring 503a.

[0057] When the linkage block 501 is pushed by the steel bar, the linkage block 501 is controlled to push the piston block 503 in the transverse hole 101c through the long curved rod 504 or the short curved rod 502, thereby pushing another piston block 503 in the transverse hole 101c to move, thereby controlling the linkage block 501 that cooperates with it to push the steel bar;

[0058] When the pushing plate 301 is reset, the piston rod 303 is driven to reset in the punching hole 102a, so that the piston block 503 is no longer compressed by the compressed gas, and then the piston block 503 is pushed by the reset spring 503a, so that the piston block 503 is reset. Example 5

[0059] The present invention also provides a method for using a steel bar length splicing device for civil engineering, which is used by the following steps:

[0060] S1: insert two steel bars into corresponding sleeves 101 respectively, and control the position of the steel bar transverse ribs to align with the position of the clamping block 201, and control the radial gap between the steel bar transverse ribs to align with the position of the linkage block 501;

[0061] S2: After the steel bar moves inside the sleeve 101, the steel bar will gradually squeeze the pushing plate 301 after it contacts the pushing plate 301, so that the pushing plate 301 controls the piston rod 303 to move out of the strip opening 101a through the air pressure control linkage block 501 and contact the smooth surface of the steel bar surface wall;

[0062] S3: When the steel bar moves and deviates inside the sleeve 101, causing the steel bar to tilt with the inside of the sleeve 101, the tilted part of the steel bar will push the linkage block 501 abutting against it, and then another linkage block 501 used in conjunction with the linkage block 501 will push the steel bar to reset its tilted direction, pushing the steel bar through two points in opposite directions, thereby correcting the steel bar;

[0063] S4: When two steel bars are connected, the two sleeves 101 are arranged opposite to each other, and the inner screw barrel 104 is controlled to be screwed on the stud 105, so that the abutment ring 401 and the limiting ring 402 are abutted, and the limiting rod 403a is inserted into the corresponding limiting hole 401a to limit the two sleeves 101.
