Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to an adjustable column main reinforcement positioning clamp. Background Technology

[0002] When pouring foundation and floor slab concrete at the construction site, the main reinforcement bars of the columns above the pouring surface need to be embedded in the pouring surface, with sufficient length left above the pouring surface to facilitate subsequent reinforcement splicing. Since concrete pouring will disturb the main reinforcement bars of the columns and affect the embedding accuracy of the main reinforcement bars, it is necessary to position the main reinforcement bars of the columns.

[0003] The traditional method for locating column main reinforcement bars involves placing multiple steel pipes around the outside of the main reinforcement bar, connecting them end-to-end to form a single unit. The main reinforcement bar is then tied to these pipes with wire to position it. This traditional method suffers from low positioning accuracy and is inconvenient and inefficient. Therefore, an adjustable column main reinforcement bar positioning clamp is needed to address the problems of low positioning accuracy, inconvenience, and inefficiency associated with the traditional method. Summary of the Invention

[0004] The purpose of this utility model is to provide an adjustable column main reinforcement positioning clamp, which can solve the problems of low positioning accuracy, inconvenient operation and low efficiency of traditional column main reinforcement positioning methods.

[0006] An adjustable column main reinforcement positioning clamp includes a positioning ruler, a middle reinforcement positioning component, and corner reinforcement positioning components. Adjacent positioning rulers are connected by corner reinforcement positioning components, so that several positioning rulers form a ring structure. This ring structure is matched and arranged around the outside of the column main reinforcement, and the corner reinforcement positioning components are matched and clamped on the first column main reinforcement located at the corner of the column. The middle reinforcement positioning component is sleeved on the positioning ruler, so that the middle reinforcement positioning component is matched and clamped on the second column main reinforcement located in the middle of the column.

[0007] The positioning ruler includes several unit positioning rulers with a first scale line. One end of each unit positioning ruler has an internal thread groove, and the other end of each unit positioning ruler has a thread protrusion that matches the internal thread groove, so that adjacent unit positioning rulers are matched and screwed together. Several unit positioning rulers are spliced ​​together to form a positioning ruler.

[0008] The unit positioning ruler has several first positioning holes spaced apart. The middle steel bar positioning component and the corner steel bar positioning component are detachably installed on the unit positioning ruler through one of the first positioning holes by positioning pins.

[0009] The intermediate rebar positioning component includes a first sliding sleeve and a first clamping part; a second positioning hole is formed on the first sliding sleeve, so that the first sliding sleeve can be slidably sleeved on the unit positioning ruler, and fixedly connected to the unit positioning ruler through the positioning pin via the second positioning hole and the first positioning hole; one end of the first clamping part is provided on the side of the first sliding sleeve near the second column main rebar, so that the annular structure of the first clamping part can be matched and clamped on the second column main rebar.

[0010] The other end of the first clamping part has an opening, and the opening is locked by bolts and nuts. The inner wall of the first clamping part is provided with an anti-slip part so that the first clamping part can be clamped on the second column main reinforcement.

[0011] The first sliding sleeve is provided with a second scale line, which can be connected to the first scale line on the unit positioning ruler.

[0012] The corner reinforcement positioning component includes a second sliding sleeve, a third sliding sleeve, and a second clamping part. One end of the second sliding sleeve is connected to the bottom of one end of the third sliding sleeve. Both the second and third sliding sleeves have third positioning holes, allowing the second and third sliding sleeves to be slidably fitted onto two adjacent positioning rulers. They are then fixedly connected to the unit positioning rulers via positioning pins through the third positioning hole and the first positioning hole. One end of the second clamping part is located on the side of the second or third sliding sleeve near the main reinforcement of the first column, so that the second clamping part of the annular structure can be matched and clamped onto the main reinforcement of the first column.

[0013] The other end of the second clamping part has an opening, and the opening is locked by bolts and nuts. The inner wall of the second clamping part is provided with an anti-slip part so that the second clamping part can be clamped on the main rib of the first column.

[0014] The second sliding sleeve is provided with a third scale line, which is connected to the first scale line on one of the unit positioning rulers of the adjacent positioning ruler.

[0015] The second sliding sleeve is provided with a fourth scale line, and the third sliding sleeve is provided with a fifth scale line. The fourth and fifth scale lines are connected to the first scale line on another unit positioning ruler of the adjacent positioning ruler.

[0016] Compared with the prior art, this utility model has the following advantages:

[0017] 1. This utility model has a positioning ruler. The unit positioning ruler is screwed together, which can be flexibly spliced ​​according to the size of the column. It has good versatility and applicability for different columns, and is easy to assemble and disassemble.

[0018] 2. This utility model has an intermediate steel bar positioning component, which is slidably connected to the positioning ruler through the first sliding sleeve. It can be flexibly adjusted and has good versatility and applicability for the second column main bars with different spacing in the column body.

It is easy to disassemble and assemble, and at the same time, it can ensure the positioning accuracy of the second column main bars through the scale line.

[0019] 3. This utility model features a corner reinforcement positioning component. The corner reinforcement positioning component is connected to the adjacent positioning ruler through the second and third sliding sleeves. It is used for splicing the positioning ruler to form an integral ring structure and is placed around the outside of the column main reinforcement.

[0028] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0029] Please see the appendix Figure 1 and attached Figure 2 An adjustable column main reinforcement positioning clamp includes a positioning ruler 1, a middle reinforcement positioning component 2, and a corner reinforcement positioning component 3. Two adjacent positioning rulers 1 are connected by the corner reinforcement positioning component 3, so that several positioning rulers 1 form a ring structure. This ring structure is matched and arranged around the outside of the column main reinforcement, and the corner reinforcement positioning component 3 is matched and clamped on the first column main reinforcement 401 located at the corner of the column. The middle reinforcement positioning component 2 is sleeved on the positioning ruler 1, so that the middle reinforcement positioning component 2 is matched and clamped on the second column main reinforcement 402 located in the middle of the column.

[0030] Most columns are rectangular or directional. Preferably, four positioning rulers 1 are installed, forming a rectangular ring structure around the outside of the main reinforcement bars of the column. According to the number of main reinforcement bars in the column, intermediate reinforcement positioning pieces 2 and corner reinforcement positioning pieces 3 are installed. Four corner reinforcement positioning pieces 3 are located at the four corners of the rectangular ring structure. They are used to connect adjacent positioning rulers 1, making the ring structure a whole, and also to clamp the first main reinforcement bar 401 at the corner of the column, thus positioning the first main reinforcement bar 401 at the corner of the column. The intermediate reinforcement positioning pieces 2 are used to clamp the second main reinforcement bar 402 between the first main reinforcement bars 401, thus positioning the second main reinforcement bar 402 in the middle of the column. All the main reinforcement bars are relatively fixed on the ring structure, forming a stable whole structure and preventing the main reinforcement bars from being disturbed by concrete pouring, etc.

[0031] Please see the appendix Figure 3 The positioning ruler 1 includes several unit positioning rulers 101 with first scale lines 104. One end of each unit positioning ruler 101 is formed with an internal thread groove (not shown in the figure), and the other end of each unit positioning ruler 101 is formed with a threaded protrusion 102 that matches the internal thread groove, so that adjacent two unit positioning rulers 101 are matched and screwed together, and several unit positioning rulers 101 are spliced ​​together to form the positioning ruler 1.

[0032] Preferably, the unit positioning ruler 101 can be made of a round steel tube with an outer diameter of 20mm, a wall thickness of 5mm, and a length of 240mm. One end of the round steel tube has a 12mm threaded groove drilled into its inner wall, and the other end of the round steel tube has a smaller diameter round steel tube welded to its outer wall as a threaded protrusion 102, facilitating the threaded splicing of adjacent unit positioning rulers 101. The specifications of the unit positioning ruler 101 can also be adaptively adjusted according to actual usage requirements to form a standard part, thus allowing for flexible splicing of positioning rulers 1 according to the dimensions of the column, resulting in a wide range of applications.

[0033] Preferably, the accuracy of the first scale line 104 on the unit positioning ruler 101 is 10mm, but the accuracy of the first scale line 104 can also be adjusted according to actual needs.

[0034] Please see the appendix Figure 3 The unit positioning ruler 101 has several first positioning holes 103 formed at intervals. The middle steel bar positioning component 2 and the corner steel bar positioning component 3 are respectively detachably installed on the unit positioning ruler 101 through one of the first positioning holes 103 via positioning pins 5.

[0035] Preferably, the center of the first positioning hole 103 is located at the scale mark of the first scale line 104, and the center distance between two adjacent first positioning holes 103 is 20mm, that is, a first positioning hole 103 is opened every two scale marks. The hole diameter, center distance, etc. of the first positioning hole 103 can be adaptively adjusted according to actual usage requirements.

[0036] Please see the appendix Figure 4 The intermediate steel bar positioning component 2 includes a first sliding sleeve 201 and a first clamping part 202. A second positioning hole (not shown in the figure) is formed on the first sliding sleeve 201, so that the first sliding sleeve 201 can be slidably sleeved on the unit positioning ruler 101, and is fixedly connected to the unit positioning ruler 101 through the positioning pin 5 via the second positioning hole and the first positioning hole 103. One end of the first clamping part 202 is provided on the side surface of the first sliding sleeve 201 near the second column main bar 402, so that the annular structure of the first clamping part 202 can be matched and clamped on the second column main bar 402.

[0037] Preferably, the first sliding sleeve 201 can be made of a round steel tube with a length of 40mm and an outer diameter of 28mm. This facilitates the fitting of the first sliding sleeve 201 onto the unit positioning ruler 101 and allows it to slide smoothly along the unit positioning ruler 101, thereby adjusting the first clamping part 202 to the corresponding position according to the position of the second column main reinforcement 402. After adjustment, the first sliding sleeve 201 can be limited on the unit positioning ruler 101 by the positioning pin 5. The size of the positioning pin 5 is slightly smaller than the diameter of the second positioning hole and the first positioning hole 103.

[0038] Preferably, the first clamping part 202 can be a clamp, which can be made of a thin steel plate or other material with certain deformation properties, so as to facilitate the second column main reinforcement 402 to be embedded into the first clamping part 202 and locked and fixed.

[0039] Please see the appendix Figure 4 The other end of the first clamping part 202 has an opening, and the opening is locked by bolts and nuts. The inner wall of the first clamping part 202 is provided with an anti-slip part 6 so that the first clamping part 202 can be clamped on the second column main rib 402.

[0040] Preferably, the anti-slip part 6 can be made of rubber material, which has the characteristics of anti-slip, wear resistance and deformability. It can adapt to the clamping of column main reinforcement of different sizes through deformation, and at the same time ensure the clamping stability of column main reinforcement.

[0041] The opening allows the second column main reinforcement 402 to be easily embedded into the clamp and locked with bolts and nuts. The clamp can adapt to the deformation of the second column main reinforcement 402 of different sizes.

[0042] Please see the appendix Figure 4 The first sliding sleeve 201 is provided with a second scale line 203, which can be connected to the first scale line 104 on the unit positioning ruler 101.

[0043] Preferably, the accuracy of the second scale line 203 is 10mm, and three scale marks are set at equal intervals on the first sliding sleeve 201 to improve the positioning accuracy of the intermediate steel bar positioning piece 2 and the second column main reinforcement 402.

[0044] Please see the appendix Figure 5 and attached Figure 6 The corner steel bar positioning component 3 includes a second sliding sleeve 301, a third sliding sleeve 302, and a second clamping part 303. One end of the second sliding sleeve 301 is connected to the bottom of one end of the third sliding sleeve 302. Both the second sliding sleeve 301 and the third sliding sleeve 302 have a third positioning hole (not shown in the figure), so that the second sliding sleeve 301 and the third sliding sleeve 302 can be slidably sleeved on two adjacent positioning rulers 1, and are fixedly connected to the unit positioning ruler 101 through the positioning pin 5 via the third positioning hole and the first positioning hole 103. One end of the second clamping part 303 is provided on the side surface of the second sliding sleeve 301 or the third sliding sleeve 302 near the first column main reinforcement 401, so that the annular structure of the second clamping part 303 can be matched and clamped on the first column main reinforcement 401.

[0045] Preferably, both the second sliding sleeve 301 and the third sliding sleeve 302 are made of round steel tubes, with a length of 60mm and an outer diameter of 28mm. This facilitates the fitting of the second sliding sleeve 301 and the third sliding sleeve 302 onto the unit positioning ruler 101 of the adjacent positioning ruler 1, allowing them to slide smoothly along the unit positioning ruler 101. This enables the second clamping part 303 to be slidably adjusted to the corresponding position according to the position of the first column main reinforcement 401. After adjustment, the second sliding sleeve 301 and the third sliding sleeve 302 can be limited on the adjacent unit positioning ruler 101 by the positioning pins 5.

[0046] Since most of the columns are rectangular or square, the second sliding sleeve 301 and the third sliding sleeve 302 are vertically welded into a single structure. The connection angle between the second sliding sleeve 301 and the third sliding sleeve 302 can also be adjusted according to the rotation angle of the column.

[0047] Preferably, the second clamping part 303 can be a clamp, which can be made of materials such as thin steel plate with certain deformation properties, so as to facilitate the first column main reinforcement 401 to be embedded into the second clamping part 303 and locked and fixed.

[0048] Please see the appendix Figure 5 and attached Figure 6 The other end of the second clamping part 303 has an opening, and the opening is locked by bolts and nuts. The inner wall of the second clamping part 303 is provided with an anti-slip part 6 so that the second clamping part 303 can be clamped on the first column main rib 401.

[0049] Preferably, the anti-slip part 6 can be made of rubber material, which has the characteristics of anti-slip, wear resistance and deformability. It can adapt to the clamping of column main reinforcement of different sizes through deformation, and at the same time ensure the clamping stability of column main reinforcement.

[0050] The opening facilitates the embedding of the first column main reinforcement 401 into the clamp and locking it with bolts and nuts. The clamp can adapt to different sizes of the first column main reinforcement 401 by deformation.

[0051] Please see the appendix Figure 5 and attached Figure 6 The second sliding sleeve 301 is provided with a third scale line 304, which is connected to the first scale line 104 on one of the unit positioning rulers 101 of the adjacent positioning ruler 1.

[0052] Preferably, the accuracy of the third scale line 304 is 10mm, and five scale marks are equally spaced on the second sliding sleeve 301.

[0053] Please see the appendix Figure 5 and attached Figure 6The second sliding sleeve 301 is provided with a fourth scale line 305, and the third sliding sleeve 302 is provided with a fifth scale line 306. The fourth scale line 305 and the fifth scale line 306 are connected to the first scale line 104 on the other unit positioning ruler 101 of the adjacent positioning ruler 1.

[0054] Preferably, the accuracy of the fourth scale line 305 and the fifth scale line 306 is 10mm. Two scale marks are equally spaced along the width direction on the second sliding sleeve 301, namely the fourth scale line 305. Three scale marks are equally spaced along the length direction on the third sliding sleeve 302, namely the fifth scale line 306, to improve the positioning accuracy of the corner steel bar positioning piece 3 and the first column main reinforcement 401.

[0057] Based on the side length of the square column, four positioning rulers 1 of the same length are formed by splicing the threaded protrusion 102 and the internal threaded groove splicing unit positioning ruler 101, which are respectively named positioning ruler one, positioning ruler two, positioning ruler three and positioning ruler four. The length of positioning ruler 1 is greater than the side length of the square column.

[0058] First, place the two intermediate steel bar positioning pieces 2 onto the positioning ruler 1 through the first sliding sleeve 201, and then place the two corner steel bar positioning pieces 3 onto the positioning ruler 1 through the second sliding sleeve 301. The two first sliding sleeves 201 are located between the two second sliding sleeves 301.

[0059] Adjust the first sliding sleeve 201 and the second sliding sleeve 301 according to the arrangement spacing of the first column main reinforcement 401 and the second column main reinforcement 402, so that when the positioning ruler 1 abuts against one side column main reinforcement of the square column, the two corner first column main reinforcements 401 are precisely embedded in the two second clamping parts 303, and the two middle second column main reinforcements 402 are precisely embedded in the first clamping part 202. Lock the middle reinforcement positioning piece 2 by inserting positioning pins 5 into the first positioning hole 103 and the second positioning hole, and lock the corner reinforcement positioning pieces 3 by inserting positioning pins 5 into the first positioning hole 103 and the third positioning hole. Tighten the bolts and nuts on the second clamping part 303 and the first clamping part 202 to connect the column main reinforcement and the positioning ruler 1 into a whole.

[0061] Using the same method, the two intermediate steel bar positioning pieces 2 and one corner steel bar positioning piece 3 are fitted onto positioning ruler two and positioning ruler four, and connected and fixed to the first column main bar 401 and the second column main bar 402 on both sides of the square column. This will not be described in detail here.

[0062] After attaching two intermediate steel bar positioning pieces 2 to positioning ruler four, insert both ends of positioning ruler four into positioning ruler two and the third sliding sleeve 302 of positioning ruler four respectively. Use the same method to connect and fix the two intermediate steel bar positioning pieces 2 to the second column main reinforcement 402. This will not be described in detail here.

[0063] The ring structure formed by the four positioning rulers 1 is connected to the 12 main column bars through the four corner steel bar positioning pieces 3 and the eight middle steel bar positioning pieces 2 to form a whole. It is used to position the main column bars and the spacing, prevent the main column bars from being disturbed and deviated, and facilitate the subsequent splicing of steel bars.
