Description
Technical Field
[0001] The present application relates to the technical field of steel bar connection tools, and in particular to a common rail tool for upper and lower steel bar wire heads of a steel bar skeleton. Background Art
[0002] In the field of construction engineering, it is often necessary to connect multiple fixed steel bars in groups to form a certain steel skeleton of the building structure. The steel skeleton plays a role in strengthening support and connection in the concrete structure, and improves the tensile and compressive strength of the concrete components.
[0003] However, during the lifting and connection process of the steel frame, due to certain errors in binding, there are gaps of different lengths at the joints of the upper and lower steel bars, which makes it impossible for the axes of the upper and lower steel bars to be on the same track. In this case, the connecting joints cannot smoothly connect the upper and lower steel bars, thereby increasing the overall construction difficulty of the steel frame, increasing the time spent by workers on assembling the steel frame, and reducing construction efficiency, which is an obvious shortcoming. Utility Model Content
[0004] In order to improve the construction efficiency of the steel frame, the present application provides a common rail tool for the upper and lower steel wire heads of the steel frame.
[0005] The present application provides a common rail tool for the upper and lower steel wire heads of a steel frame, which adopts the following technical solution:
[0006] A common track tool for upper and lower steel bar wire heads of a steel bar skeleton, comprising a first guide rod and a second guide rod, wherein the first guide rod and the second guide rod are located on the same straight line, connecting plates are provided at both ends of the first guide rod and the second guide rod, fixing components for fixing the steel bars are provided on the connecting plates, and an adjusting member is provided between the first guide rod and the second guide rod, wherein the adjusting member is used to adjust the distance between the first guide rod and the second guide rod.
[0007] By adopting the above technical solution, when the upper and lower steel bars are not on the same track, the workers fix the upper steel bars on the first guide rod and the lower steel bars on the second guide rod through the fixing assembly. Then the workers adjust the gap between the upper and lower steel bar wire heads through the adjusting piece according to the spacing between the upper and lower steel bar wire heads. When the upper and lower steel bar wire heads abut against each other, under the coaxial guidance of the first guide rod and the second guide rod, the axes of the upper and lower steel bars are on the same track. At this time, the connecting joints can smoothly connect the upper and lower steel bars. After the connection is completed, the upper and lower steel bars are taken out, and the above steps are repeated until all the upper and lower connecting joints on the steel skeleton are connected. Such a setting reduces the overall construction difficulty of the steel skeleton, thereby shortening the time spent by workers on assembling the steel skeleton and improving construction efficiency.
[0008] Optionally, the fixing assembly includes a baffle plate, which together with the connecting plate forms a steel bar slot, a threaded rod is threadedly connected to the side wall of the connecting plate, a clamping rod is provided at one end of the threaded rod, the clamping rod is slidably arranged in the steel bar slot, and one end of the clamping rod away from the threaded rod abuts against the steel bar.
[0009] By adopting the above technical solution, when it is necessary to fix the steel bars, the threaded rod is rotated, and the rotation of the threaded rod drives the clamping rod to move in the steel bar slot. The steel bars are fastened in the steel bar slot under the push of the clamping rod. The setting of the fixing component improves the stability of the steel bars in the steel bar slot and ensures the smooth connection of the upper and lower steel bars.
[0010] Optionally, the baffle is obliquely arranged on the connecting plate, and an angle between the baffle and the connecting plate is an acute angle.
[0011] By adopting the above technical solution, the inclined baffle plate limits the steel bars in the steel bar slot, reducing the occurrence of the steel bars rolling and escaping from the steel bar slot, thereby further improving the stability of the steel bars in the steel bar slot.
[0012] Optionally, a rubber pad is provided at one end of the clamping rod away from the threaded rod.
[0013] By adopting the above technical solution, the rubber pad can reduce the pressing force on the steel bar when it is pressed, and reduce the possibility of deformation of the steel bar due to the pressing force. The rubber pad plays a protective role on the steel bar.
[0014] Optionally, the adjusting member is a positive and negative thread sleeve, and both ends of the positive and negative thread sleeve are respectively provided with a positive thread thread and a negative thread thread, the first guide rod is threadedly connected to the positive thread, and the second guide rod is threadedly connected to the negative thread.
[0015] By adopting the above technical solution, after the upper and lower steel bars are inserted into the steel bar slots, the workers rotate the forward and reverse wire sleeves according to the spacing between the upper and lower steel bar thread heads. The rotation of the forward and reverse wire sleeves drives the first guide rod and the second guide rod to move in a direction close to each other, and at the same time drives the upper and lower steel bars closer to each other. When the upper and lower steel bars abut, the workers connect the upper and lower steel bars. The setting of the forward and reverse wire sleeves makes it convenient for workers to flexibly adjust the distance between the upper and lower steel bars. Workers do not need to repeatedly fix the steel bars to adjust the distance between the upper and lower steel bars, thereby further improving construction efficiency.
[0016] Optionally, a plurality of anti-slip convex grooves are provided on the outer side walls of the positive and negative wire sleeves.
[0017] By adopting the above technical solution, the provision of the anti-slip convex pattern increases the friction between the worker's palm and the forward and reverse thread sleeves, thereby making it more convenient for the worker to twist the forward and reverse thread sleeves.
[0018] Optionally, the first guide rod, the second guide rod and the forward and reverse wire sleeves are all made of steel.
[0019] By adopting the above technical solution, the overall rigidity strength of the common rail tool is improved by using steel material.
[0020] Optionally, the fixing assembly includes a mounting plate, which together with the connecting plate form a fixing groove, in which two fixing plates are slidably connected, and in which a bidirectional screw rod is rotatably connected, one end of the two fixing plates are respectively threadedly connected to two sections of the rod body of the bidirectional screw rod with opposite thread rotation directions, and the other end is provided with a sliding block, and a sliding groove that slidably cooperates with the sliding block is opened on the inner side wall of the fixing groove.
[0021] By adopting the above technical solution, when the worker places the steel bar into the fixing groove, he rotates the bidirectional screw rod, and the rotation of the bidirectional screw rod drives the two fixing plates to move toward the direction close to the steel bar. When the fixing plate contacts the steel bar, the steel bar is fixed in the fixing groove. At this time, both ends of the steel bar are fixed by the fixing plate, the contact area between the steel bar and the fixing plate is expanded, and the stability of the steel bar during connection is further improved.
[0022] In summary, the present application includes at least one of the following beneficial technical effects:
[0023] 1. The present application provides a first guide rod, a fixing assembly and a second guide rod, and realizes the coaxial and common track of the upper and lower steel bars through the guiding effect of the first guide rod and the second guide rod on the upper and lower steel bars, and at the same time, the fixing assembly improves the stability of the upper and lower steel bars when connected;
[0024] 2. This application provides an adjustment piece, which makes it convenient for workers to flexibly adjust the distance between the upper and lower steel bars. Workers do not need to repeatedly fix the steel bars to adjust the distance between the upper and lower steel bars, thereby further improving construction efficiency.

DETAILED DESCRIPTION
[0030] The following is combined with Figure 1-4 This application is described in further detail.
[0031] Example 1
[0032] An embodiment of the present application provides a common rail tool for the upper and lower steel wire heads of a steel frame.
[0033] Reference Figure 1 A common track tool for upper and lower steel bar wire heads of a steel bar skeleton includes a first guide rod 1 and a second guide rod 2. The first guide rod 1 and the second guide rod 2 are arranged opposite to each other and their axes are on the same straight line. The first guide rod 1 and the second guide rod 2 are used to guide the common track of the upper and lower steel bars. Connecting plates 3 are fixedly installed at both ends of the first guide rod 1 and the second guide rod 2. The connecting plate 3 is L-shaped. A fixing component 4 for fixing the steel bars is arranged on the connecting plate 3. An adjusting member 5 is arranged between the first guide rod 1 and the second guide rod 2. The adjusting member 5 is used to adjust the distance between the first guide rod 1 and the second guide rod 2.
[0034] Reference Figure 2 The fixing assembly 4 includes a baffle 41 and a threaded rod 42. The baffle 41 is fixedly installed on the connecting plate 3 and encloses the connecting plate 3 to form a steel bar slot 6. The baffle 41 is arranged at an angle, and the angle between the baffle 41 and the connecting plate 3 is an acute angle to better limit the steel bar. The threaded rod 42 is threadedly connected to the side wall of the connecting plate 3 and passes through the connecting plate 3 to extend into the steel bar slot 6. A clamping rod 43 is provided at one end of the threaded rod 42 located in the steel bar slot 6. The clamping rod 43 is slidably connected to the inside of the steel bar slot 6. A rubber pad 7 is installed at the end of the clamping rod 43 away from the threaded rod 42 to reduce the clamping force on the steel bar and protect the steel bar.
[0035] After the worker places the steel bar into the steel bar slot 6, the worker rotates the threaded rod 42, and the rotation of the threaded rod 42 drives the clamping rod 43 to move toward the direction close to the steel bar until the rubber pad 7 is tightly in contact with the steel bar, thereby fixing the steel bar in the steel bar slot 6. The setting of the fixing component 4 improves the stability of the steel bar in the steel bar slot 6 and ensures the smooth connection of the upper and lower steel bars.
[0036] Reference Figure 2 and Figure 3The adjusting member 5 is a positive and negative thread sleeve 51, and both ends of the positive and negative thread sleeve 51 are respectively provided with positive thread threads and negative thread threads, wherein the first guide rod 1 is threadedly connected to the positive thread threads, and the second guide rod 2 is threadedly connected to the negative thread threads.
[0037] After the upper and lower steel bars are inserted into the steel bar slot 6, the worker rotates the positive and negative wire sleeves 51 according to the spacing between the upper and lower steel bar thread heads. The rotation of the positive and negative wire sleeves 51 drives the first guide rod 1 and the second guide rod 2 to move in a direction close to each other, and at the same time drives the upper and lower steel bars to approach each other. When the upper and lower steel bars abut, the worker connects the upper and lower steel bars. The setting of the positive and negative wire sleeves 51 is convenient for the workers to flexibly adjust the distance between the upper and lower steel bars. The workers do not need to repeatedly fix the steel bars to adjust the distance between the upper and lower steel bars, thereby further improving the construction efficiency.
[0038] Reference Figure 3 In order to improve the convenience of rotating the forward and reverse wire sleeve 51, a plurality of anti-skid convex patterns 8 are arranged on the outer wall of the forward and reverse wire sleeve 51. The arrangement of the anti-skid convex patterns 8 increases the friction between the palm and the forward and reverse wire sleeve 51, making it easier to rotate the forward and reverse wire sleeve 51.
[0039] Reference Figure 3 The first guide rod 1, the second guide rod 2 and the adjusting member 5 are all made of high-strength steel. The high-strength steel can improve the structural strength and service life of the overall common rail tool, ensuring that the common rail tool will not be deformed or damaged during long-term use.
[0040] The implementation principle of Example 1 is: during the connection of the steel bar skeleton, the thread heads of the upper and lower steel bars may not be on the same track due to errors in binding. At this time, the upper steel bar is inserted into the steel bar slot 6 on the first guide rod 1, and the lower steel bar is inserted into the steel bar slot 6 on the second guide rod 2. The first guide rod 1 and the second guide rod 2 are used to guide the steel bar thread heads to align. After being fixed by the fixing component 4, the worker adjusts the gap between the upper and lower steel bar thread heads according to the spacing between the upper and lower steel bar thread heads and through the adjustment member 5. When the upper and lower steel bar thread heads abut against each other, under the coaxial guidance of the first guide rod 1 and the second guide rod 2, the axes of the upper and lower steel bars are on the same track. At this time, the connecting joint can smoothly connect the upper and lower steel bars. After the connection is completed, the upper and lower steel bars are taken out, and the above steps are repeated until all the upper and lower connecting joints on the steel bar skeleton are connected. This arrangement reduces the overall construction difficulty of the steel bar skeleton, thereby shortening the time spent by workers on assembling the steel bar skeleton and improving construction efficiency.
[0041] Example 2
[0042] The difference between this embodiment and the first embodiment is that the structure of the fixing component 4 is different.
[0043] Reference Figure 4The fixing assembly 4 in this embodiment includes a mounting plate 44 and a bidirectional screw rod 45. The mounting plate 44 and the connecting plate 3 are enclosed to form a fixing groove 9. Two fixing plates 46 are slidably connected in the fixing groove 9. The fixing plate 46 is arc-shaped to better adapt to the shape of the steel bar. The bidirectional screw rod 45 is rotatably connected in the fixing groove 9 and passes through the connecting plate 3 and the mounting plate 44 in sequence. One end of the two fixing plates 46 is respectively threadedly connected to the two sections of the rod body with opposite thread rotation directions of the bidirectional screw rod 45, and the other end is fixedly connected with a slider 461. A sliding groove 91 that slidably cooperates with the slider 461 is opened on the inner side wall of the fixing groove 9.
[0044] The implementation principle of Example 2 is: after the worker places the steel bar into the fixing groove 9, the bidirectional screw rod 45 is rotated, and the rotation of the bidirectional screw rod 45 drives the two fixing plates 46 to move toward the direction close to the steel bar. When the fixing plates 46 contact the steel bar, the steel bar is fixed in the fixing groove 9. At this time, both ends of the steel bar are fixed by the fixing plates 46, the contact area between the steel bar and the fixing plates 46 is enlarged, and the stability of the steel bar during connection is further improved.
[0045] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
