Description

Technical Field

[0001] The utility model relates to a steel bar positioning device, in particular to an adjustable rectangular frame column steel bar positioning and perpendicularity control device. Background Technique

[0002] The cast-in-place frame structure is a common building structure form, which is a structure in which the frame composed of beams, columns and slabs bears all the loads of the house. Among them, the frame column is the most basic load-bearing member in the engineering structure, and "strong columns and weak beams" is one of the important principles to be followed in the seismic design of the frame part. The longitudinal steel bars in the column and the concrete jointly bear the axial pressure and the possible eccentric moment, and have relatively high requirements for the positioning and perpendicularity accuracy of the longitudinal steel bars. If the position and perpendicularity of the longitudinal steel bars do not meet the requirements, lateral stress will be generated, thus affecting the service life of the building structure. Therefore, the positioning and perpendicularity control of the longitudinal steel bars of the frame column is a very important link.

[0003] When installing the longitudinal steel bars of the concrete frame column by using the traditional manual positioning method, usually only a few steel bars can be positioned and fixed, the steel bar binding is difficult, it consumes manpower, and the fixed positioning efficiency is low and the safety is poor; when using general positioning clamps for positioning and perpendicularity control of the steel bars of frame columns with different cross-sections, it is necessary to customize multiple sizes of cross-sections, which consumes material resources and the process is complex and inconvenient. Content of the Utility Model

[0004] The purpose of the utility model is to provide an adjustable rectangular frame column steel bar positioning and perpendicularity control device to solve the problems of low efficiency of the existing longitudinal steel bar positioning technology for concrete frame columns and inadaptability to frame columns with different cross-sections.

[0005] The utility model is realized as follows: an adjustable rectangular frame column steel bar positioning and perpendicularity control device, including four adjusting frames, the adjusting frame includes a first arm and a second arm, the first arm and the second arm are connected to each other to form an L shape, and the four adjusting frames are sequentially overlapped and enclosed into a rectangle in pairs; first sliding holes and second sliding holes are arranged along the length direction on the first arm and the second arm, a first adjusting bolt is inserted through the overlapping part of the first sliding holes on two adjacent adjusting frames, a plurality of moving positioning members are inserted into the second sliding holes, the moving positioning member includes a positioning stud and a U-shaped limiting clamp located at the end of the positioning stud, and a fixing nut is arranged on the positioning stud, and the fixing nut is used to fix the moving positioning member in the second sliding hole.

[0006] As a further improvement of the adjustable rectangular frame column steel bar positioning and perpendicularity control device of the present utility model, both the first arm and the second arm include a longitudinal side plate and a transverse side plate. The cross-sections of the first arm and the second arm are both L-shaped. The first sliding hole is located on the transverse side plate, and the second sliding hole is located on the longitudinal side plate.

[0007] As a further improvement of the adjustable rectangular frame column steel bar positioning and perpendicularity control device of the present utility model, two fixing nuts are arranged on the positioning stud, and the two fixing nuts are respectively located on the inner and outer sides of the adjusting frame.

[0008] As a further improvement of the adjustable rectangular frame column steel bar positioning and perpendicularity control device of the present utility model, a fixed positioning member is arranged on the inner side of the corner of the adjusting frame. The fixed positioning member includes a positioning plate, and a fixed U-shaped clamp is arranged on the positioning plate.

[0009] As a further improvement of the adjustable rectangular frame column steel bar positioning and perpendicularity control device of the present utility model, a transition plate is further included. A third sliding hole is opened on the transition plate, and the third sliding hole coincides with the second sliding hole. A second adjusting bolt is inserted through the third sliding hole and the second sliding hole to connect the overlapping part of the transition plate and the adjusting frame. A movable positioning member is arranged on the transition plate.

[0010] The present utility model is used for positioning the steel bars of a rectangular frame column and controlling the perpendicularity. Four adjusting frames enclose a rectangular structure, and the size of the enclosed rectangular structure can be adjusted to adapt to different frame columns. Moreover, the position of the movable positioning member can be adjusted to meet the steel bar spacing requirements of the design.

[0011] The movable positioning member includes a positioning stud and a U-shaped limit clamp located at the end of the positioning stud. The U-shaped limit clamp can effectively limit the position of the longitudinal bars of the frame column. The protruding distance of the U-shaped limit clamp can be adjusted through the fixing nut on the positioning stud to ensure the contact between the U-shaped limit clamp and the longitudinal bars of the frame column.

[0012] The cross-sections of the first arm and the second arm of the adjusting frame of the present utility model are both L-shaped, which can improve the structural strength of the adjusting frame and the enclosed rectangular structure, thereby improving the stability of the entire device and the accuracy of positioning.

[0019] The structure of the utility model will be further described below with reference to the accompanying drawings.

[0020] As Figure 1 , Figure 2 and Figure 3 shown, the utility model is an adjustable rectangular frame column steel bar positioning and verticality control device, and its structure mainly includes four adjusting frames 1. The adjusting frame 1 includes a first arm 1-1 and a second arm 1-2. The first arm 1-1 and the second arm 1-2 are connected to each other to form an L shape. The four adjusting frames 1 are sequentially overlapped and enclosed in a rectangle in pairs.

[0021] First sliding holes 1-3 and second sliding holes 1-4 are provided along the length direction on the first arm 1-1 and the second arm 1-2. The first sliding hole 1-3 is used to adjust the relative position of two adjacent adjusting frames 1, and the second sliding hole 1-4 is used to install the moving positioning part 3. At the overlapping position of the two adjusting frames 1, the first adjusting bolt 2 passes through the second sliding holes 1-4 on the two adjusting frames 1 at the same time, and a nut is tightened on the first adjusting bolt 2 to fix the two adjusting frames 1 to each other.

[0022] The moving positioning part 3 includes a positioning stud 3-2 and a U-shaped limit card 3-1 located at the end of the positioning stud 3-2. A fixed nut 3-3 is threadedly connected to the positioning stud 3-2.

[0023] According to needs, a plurality of moving positioning parts 3 are arranged on the second sliding hole 1-4. The positioning stud 3-2 passes through the second sliding hole 1-4, and the positioning stud 3-2 is fixed on the second sliding hole 1-4 through the fixed nut 3-3, so as to determine the position of the moving positioning part 3 on the adjusting frame 1.

[0024] Among them, two fixing nuts 3-3 are arranged on the positioning stud 3-2, and the two fixing nuts 3-3 are respectively located on the inner and outer sides of the adjusting frame 1. The side plates of the adjusting frame 1 are clamped by the two fixing nuts 3-3 to fix the positioning stud 3-2, and the distance that the U-shaped limit card 3-1 extends can be adjusted by the two fixing nuts 3-3, so as to adjust the verticality of the longitudinal bars 8 of the frame column.

[0025] The first sliding hole 1-3 and the second sliding hole 1-4 can be in the same plane or in different planes. When the first sliding hole 1-3 and the second sliding hole 1-4 are in different planes, both the first arm 1-1 and the second arm 1-2 include a longitudinal side plate and a transverse side plate. The first sliding hole 1-3 is located on the transverse side plate, and the second sliding hole 1-4 is located on the longitudinal side plate. The cross-sections of the first arm 1-1 and the second arm 1-2 are L-shaped. Specifically, the first arm 1-1 and the second arm 1-2 can be made of angle steel. On the one hand, due to the L-shaped cross-section structure, the structural strength of the adjusting frame 1 and the entire device can be ensured; on the other hand, since the first sliding hole 1-3 and the second sliding hole 1-4 are respectively located on the transverse side plate and the longitudinal side plate, there will be no interference between the first adjusting bolt 2 for controlling the overall size of the device and the moving positioning member 3 for positioning the position of the longitudinal bars 8 of the frame column.

[0026] A fixed positioning member is arranged inside the corner of the adjusting frame 1. The fixed positioning member includes a positioning plate 4, and a fixed U-shaped clamp 5 is arranged on the positioning plate 4. When the four adjusting frames 1 are connected to form a rectangular structure, the four fixed U-shaped clamps 5 are located at the four corners of the rectangular structure. At this time, the four fixed U-shaped clamps 5 correspond to the longitudinal bars at the four corners of the rectangular frame column. The fixed U-shaped clamp 5 can be directly welded to the positioning plate 4 or can be adjustably installed on the positioning plate 4 through a stud.

[0027] Generally, the above structure can meet the positioning and verticality control of the steel bars of the rectangular frame column, and is applicable to frame columns of different sizes and different steel bar spacing requirements. However, since the second sliding hole 1-4 is not arranged along the entire length of the adjusting frame 1, there is no second sliding hole 1-4 at the end of the first arm 1-1 or the second arm 1-2. If the moving positioning member 3 is installed according to the required steel bar spacing, it is possible that the position of the moving positioning member 3 just coincides with the position without the second sliding hole 1-4, resulting in the positioning stud 3-2 of the moving positioning member 3 being unable to pass through the overlapping part of the two adjusting frames 1.

[0028] Therefore, as Figure 4 、 Figure 5As shown in the figure, the utility model further includes a transition plate 6. A third sliding hole 6-1 is formed in the transition plate 6. During use, the transition plate 6 is placed at the overlapping part of the two adjusting frames 1. The transition plate 6 abuts against the outer side surface of the longitudinal side plate, and the third sliding hole 6-1 coincides with the second sliding hole 1-4. A second adjusting bolt 7 is inserted through the third sliding hole 6-1 and the second sliding hole 1-4. The overlapping part of the transition plate 6 and the adjusting frame 1 is connected through the second adjusting bolt 7. The upper part of the transition plate 6 extends beyond the longitudinal side plate. The positioning stud 3-2 of the moving positioning member 3 passes through the transition plate 6. The protruding distance of the U-shaped limit card 3-1 is adjusted through the fixing nut 3-3 and the positioning stud 3-2 is fixed. In this way, the moving positioning member 3 can be arranged at a position where the positioning stud 3-2 cannot pass through at the overlapping part.

[0029] The using method of the utility model is as follows: The four adjusting frames 1 are overlapped pairwise to form a rectangular structure. The first adjusting bolt 2 is inserted through the first sliding hole 1-3 of the overlapping section. A plurality of moving positioning members 3 are arranged in the second sliding hole 1-4, and the fixing nuts 3-3 are not tightened first. Before the longitudinal bars 8 of the frame column are tied, the utility model is placed on the outer side of the frame column. The overall dimension of the utility model is adjusted by adjusting the length of the overlapping section according to the size of the cross-section of the frame column, so that the longitudinal bars at the four corner positions are located in the card slots of the four fixed U-shaped cards 5 of the utility model, and the longitudinal bars at other positions are respectively located in the card slots of the moving positioning members 3. The adjusting frames 1 are fixedly connected to each other through the first adjusting bolt 2. The position of the moving positioning member 3 is adjusted along the second sliding hole 1-4 to make the spacing of the longitudinal bars meet the requirements, and the protruding length of the U-shaped limit card 3-2 is adjusted to control the verticality of the longitudinal bars. Then the fixing nuts 3-3 are tightened to make the spacing and verticality of the longitudinal bars 8 of the frame column meet the requirements. After the stirrups of the longitudinal bars 8 of the frame column are tied, the concrete of the frame column is poured. After the concrete solidifies, the utility model can be removed and left for repeated use.

[0030] The utility model is formed by enclosing a rectangular structure with four adjusting frames 1, and the size of the enclosed rectangular structure can be adjusted to adapt to different frame columns. Moreover, the position of the moving positioning member 3 can be adjusted to make the steel bar spacing meet the design requirements. At the same time, the utility model can adjust the protruding distance of the U-shaped limit card 3-1 through the fixing nut 3-3 on the positioning stud 3-2, so as to further ensure the verticality of the steel bars.
