Description

Technical Field

[0001] This invention relates to the field of building construction, and specifically to a device for manufacturing stirrups for cap beams and its method of use. Background Technology

[0002] The processing of the stirrups for the cap beam is generally carried out by the steel bar processing plant and then transported to the site for installation. This requires precise cutting by the steel bar processing plant. However, in the actual construction process, the cutting accuracy is often insufficient, resulting in a low pass rate for the stirrup spacing of the cap beam. When the stirrup size deviation is large, the size needs to be adjusted on site to complete the construction, which affects the on-site construction efficiency and makes it difficult to guarantee the construction quality. Summary of the Invention

[0003] The purpose of this invention is to overcome the defects of the prior art and provide a device for manufacturing stirrups for cap beams and a method for using them. This invention solves the problem of low accuracy in stirrup cutting. By using this device to manufacture stirrups, the stirrup dimensions can be matched with the corresponding positions of the cap beams, thereby improving the stirrup qualification rate, increasing construction efficiency, and ensuring construction quality.

[0004] The technical solution to achieve the above objectives is:

[0005] This invention provides a device for manufacturing stirrups for cap beams, comprising:

[0006] A horizontal bar that supports the top surface of the cap beam frame;

[0007] A telescopic rod, vertically connected to the end of a horizontal bar and adjustable in length, has a first slot on its side for fixing reinforcing bars. By adjusting the length of the telescopic rod, the end furthest from the horizontal bar is flush with the bottom surface of the cap beam frame; and

[0008] A rotating rod is installed at the end of the telescopic rod away from the horizontal bar. A clamping plate is fixed on the side of the rotating rod away from the horizontal bar. The plate is clamped in the first clamping groove by a steel bar. Rotating the rotating rod will cause the clamping plate to push against the steel bar, thereby bending the steel bar.

[0009] This invention employs a device for fabricating stirrups for cap beams. By using a horizontal bar and a telescopic bar to determine the actual stirrup width at the location where stirrups will be installed in the cap beam frame, the vertical portion of one side of the U-shaped reinforcing bar is clamped into the first slot. Rotating the rotating rod causes a clamping plate on the rotating rod to push against the reinforcing bar, thus bending it. The other side of the reinforcing bar is then clamped into the first slot. Rotating the rotating rod again bends the reinforcing bar, thus bending it into a rectangular stirrup. This solves the problem of low stirrup cutting accuracy. By using this device to fabricate stirrups, the stirrup dimensions can match the corresponding position of the cap beam, improving the stirrup qualification rate, increasing construction efficiency, and ensuring construction quality.

[0010] A further improvement of the device for manufacturing the stirrups of the cap beam of the present invention is that it also includes a caliper fixed to the end of the telescopic rod away from the horizontal rod and opposite to the horizontal rod. By adjusting the length of the telescopic rod, the caliper is made to abut against the bottom surface of the cap beam frame.

[0011] A further improvement of the device for manufacturing the stirrups of the cap beam of the present invention is that the telescopic rod includes a sleeve vertically connected to one end of the horizontal rod and an adjusting rod inserted into the sleeve. A rotating rod is rotatably connected to the end of the adjusting rod away from the sleeve. The length of the telescopic rod can be changed by moving the adjusting rod back and forth along the sleeve.

[0012] A further improvement of the device for manufacturing the stirrups of the cap beam of the present invention is that it also includes a screw hole opened on the side of the sleeve and a bolt screwed into the screw hole. By tightening the bolt, the bolt abuts against the adjusting rod, thereby fixing the position of the adjusting rod.

[0013] A further improvement of the device for manufacturing the stirrups of the cap beam of the present invention is that it further includes two first fixing rods disposed opposite to each other on the side of the telescopic rod, the spacing between the two first fixing rods being matched with the diameter of the reinforcing bar to form a first slot.

[0014] A further improvement of the device for manufacturing the stirrups of the cap beam of the present invention is that it also includes a bearing installed at the end of the telescopic rod near the rotating rod, wherein the inner ring of the bearing is fixedly connected to the telescopic rod and the outer ring of the bearing is fixedly connected to the rotating rod.

[0015] A further improvement of the device for manufacturing the stirrups of the cap beam of the present invention is that it further includes a second slot disposed on the inner ring of the bearing and corresponding to the first slot, and the reinforcing bar is secured in the second slot.

[0016] A further improvement of the device for manufacturing the stirrups of the cap beam of the present invention is that it further includes two second fixing rods disposed opposite to each other on the inner ring of the bearing, the spacing between the two second fixing rods being matched with the diameter of the reinforcing bar to form a second slot.

[0017] A further improvement of the device for manufacturing stirrups for cap beams of the present invention is that it further includes a positioning rod that is horizontal and fixed to the side of the telescopic rod. The positioning rod is perpendicular to the horizontal rod, and the length of the positioning rod matches the set spacing between two adjacent stirrups on the steel beam frame.

[0018] This invention provides a method for using a device for fabricating stirrups for cap beams, comprising the following steps:

[0019] The device is provided to hold the horizontal bar against the top surface of the cap beam frame and adjust the length of the telescopic bar so that the end of the telescopic bar away from the horizontal bar is flush with the bottom surface of the cap beam frame.

[0020] Provide reinforcing bars and clamp them into the first slot so that the reinforcing bars are vertically installed along the telescopic rod;

[0021] Rotate the rotating rod to cause the clamping plate to push against the corresponding position of the steel bar, thereby bending the steel bar. Attached Figure Description

[0024] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0025] This invention employs a device for fabricating stirrups for cap beams. By using a horizontal bar and a telescopic bar to determine the actual stirrup width at the location where stirrups will be installed in the cap beam frame, the vertical portion of one side of a U-shaped reinforcing bar is engaged in a first slot. Rotating the rotating rod causes a clamping plate on the rotating rod to push against the reinforcing bar, thus bending it. The other vertical portion of the reinforcing bar is then engaged in the first slot. Rotating the rotating rod again bends the reinforcing bar, thus bending it into a rectangular stirrup. This solves the problem of low stirrup cutting accuracy. By using this device to fabricate stirrups, the stirrup dimensions can match the corresponding positions on the cap beam, improving the stirrup qualification rate, increasing construction efficiency, and ensuring construction quality. The fabrication device for cap beam stirrups of this invention will be described below with reference to the accompanying drawings.

[0026] See Figure 1 , Figure 1 This is a front view of the device for fabricating the stirrups for the cap beam according to the present invention. The following is in conjunction with... Figure 1 The apparatus for manufacturing the stirrups of the cap beam of the present invention will be described.

[0027] like Figure 1 and Figure 2 As shown, the apparatus for fabricating stirrups for cap beams according to the present invention includes:

[0028] Horizontal bar 11 is provided to support the top surface of the cap beam frame;

[0029] A telescopic rod 12, vertically connected to the end of the horizontal rod 11 and adjustable in length, has a first slot 123 on its side for fixing reinforcing bars. By adjusting the length of the telescopic rod 12, the end of the telescopic rod 12 furthest from the horizontal rod 11 is flush with the bottom surface of the cap beam frame.

[0030] Rotary rod 13 is installed at the end of telescopic rod 12 away from horizontal rod 11. A clamping plate 131 is fixed on the side of rotating rod 13 away from horizontal rod 11. The plate is clamped in the first clamping groove 123 by a steel bar. Rotating rotating rod 13 causes clamping plate 131 to push against steel bar, thereby bending steel bar.

[0031] Specifically, it also includes two first fixing rods that are disposed on the side of the telescopic rod 12, and the spacing between the two first fixing rods matches the diameter of the reinforcing bar to form a first slot 123.

[0032] In a preferred embodiment of the present invention, a caliper 124 is also included, which is fixed to the end of the telescopic rod 12 away from the horizontal rod 11 and opposite to the horizontal rod 11. By adjusting the length of the telescopic rod 12, the caliper 124 is made to abut against the bottom surface of the cap beam frame.

[0033] Furthermore, the telescopic rod 12 includes a sleeve 121 vertically connected to one end of the horizontal rod 11 and an adjusting rod 122 inserted into the sleeve 121. A rotating rod 13 is rotatably connected to the end of the adjusting rod 122 away from the sleeve 121. The length of the telescopic rod 12 is changed by moving the adjusting rod 122 back and forth along the sleeve 121.

[0034] Specifically, it also includes a screw hole on the side of the sleeve 121 and a bolt 1211 screwed into the screw hole. By tightening the bolt 1211, the bolt 1211 abuts against the adjusting rod 122, thereby fixing the position of the adjusting rod 122.

[0035] Furthermore, it also includes a bearing 14 installed at the end of the telescopic rod 12 near the rotating rod 13, the inner ring of the bearing 14 being fixedly connected to the telescopic rod 12, and the outer ring of the bearing 14 being fixedly connected to the rotating rod 13.

[0036] Specifically, it also includes a second slot 141 set in the inner ring of the bearing 14 and corresponding to the first slot 123. The reinforcing bar is locked in the second slot 141. When the rotating rod 13 rotates, the second slot 141 will not rotate. The function of the second slot 141 is to fix the reinforcing bar near the bending point to prevent the reinforcing bar from shifting.

[0037] Preferably, it also includes two second fixing rods disposed opposite to the inner ring of the bearing 14, the spacing between the two second fixing rods matching the diameter of the reinforcing bar to form a second slot 141.

[0038] Furthermore, it also includes a positioning rod 125 that is horizontal and fixed to the side of the telescopic rod 12. The positioning rod 125 is perpendicular to the horizontal rod 11, and the length of the positioning rod 125 matches the set spacing between two adjacent stirrups on the steel beam frame.

[0039] The specific method of using this invention is as follows:

[0040] The vertical cross-section of the cap beam is an inverted trapezoid, and the thickness at the ends of the cap beam gradually increases. The width of the cap beam does not change, so U-shaped steel bars can be prefabricated according to the width of the cap beam.

[0041] Place the horizontal bar 11 against the top surface of the cap beam frame, place the end of the positioning bar 125 away from the telescopic bar 12 against the tied stirrup, and move the adjusting bar 122 back and forth along the sleeve 121 to change the length of the telescopic bar 12, so that the caliper 124 is against the bottom surface of the cap beam frame, and then tighten the bolt 1211 so that the bolt 1211 is against the adjusting bar 122, thereby fixing the position of the adjusting bar 122.

[0042] One vertical part of the U-shaped steel bar is inserted into the first slot 123 and the second slot 141. Then, the rotating rod 13 is rotated so that the clamping plate 131 pushes against the vertical part, thereby bending the vertical part. At this time, the length of the bent vertical part matches the thickness of the cap beam frame. The other vertical part of the U-shaped steel bar is bent in the same way, so that the U-shaped steel bar forms a rectangular stirrup, and the stirrup corresponds to the size of the corresponding position of the cap beam.

[0043] The present invention also provides a method for using a device for fabricating stirrups for cap beams, the method comprising the following steps:

[0044] The manufacturing apparatus is provided, in which the horizontal bar 11 is pressed against the top surface of the cap beam frame, and the length of the telescopic bar 12 is adjusted so that the end of the telescopic bar 12 away from the horizontal bar 11 is flush with the bottom surface of the cap beam frame.

[0045] Provide reinforcing bars and clamp them into the first slot 123 so that the reinforcing bars are vertically set along the telescopic rod 12;

[0046] Rotate the rotating rod 13 to drive the clamping plate 131 to push against the corresponding position of the steel bar, thereby bending the steel bar.

[0047] The specific operation method of the usage method provided by this invention is as follows:

[0048] The vertical cross-section of the cap beam is an inverted trapezoid, and the thickness at the ends of the cap beam gradually increases. The width of the cap beam does not change, so U-shaped steel bars can be prefabricated according to the width of the cap beam.

[0049] Place the horizontal bar 11 against the top surface of the cap beam frame, place the end of the positioning bar 125 away from the telescopic bar 12 against the tied stirrup, and move the adjusting bar 122 back and forth along the sleeve 121 to change the length of the telescopic bar 12, so that the caliper 124 is against the bottom surface of the cap beam frame, and then tighten the bolt 1211 so that the bolt 1211 is against the adjusting bar 122, thereby fixing the position of the adjusting bar 122.

[0050] One vertical part of the U-shaped steel bar is inserted into the first slot 123 and the second slot 141. Then, the rotating rod 13 is rotated so that the clamping plate 131 pushes against the vertical part, thereby bending the vertical part. At this time, the length of the bent vertical part matches the thickness of the cap beam frame. The other vertical part of the U-shaped steel bar is bent in the same way, so that the U-shaped steel bar forms a rectangular stirrup, and the stirrup corresponds to the size of the corresponding position of the cap beam.

[0051] The present invention has been described in detail above with reference to the accompanying drawings and embodiments. Those skilled in the art can make various modifications to the present invention based on the above description.
