Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of building construction, and particularly relates to a frame column formwork mounting and fixing structure. BACKGROUND

[0002] In the field of building construction, the frame column formwork is a temporary support structure for pouring reinforced concrete frame columns, which is usually formed by four pieces of formwork to enclose a rectangular pouring space and is reinforced and fixed by its outer side fixing structure. The installation quality of the frame column formwork directly affects the cross-sectional size accuracy and perpendicularity of the frame column. The traditional formwork reinforcement technology generally uses steel pipes as column hoops, which are locked together by cross-shaped fasteners to form rigid constraints, or the formwork surface is drilled to pass through the tensioning screw rod to implement bidirectional tensioning reinforcement. However, the reinforcement technology construction is complicated, the formwork drilling increases the formwork loss rate, and the secondary plugging and repair of the through holes are required, and the linear contact between the steel pipe and the formwork back frame leads to insufficient effective contact area, which is prone to stress concentration and causes local deformation or even expansion of the formwork.

[0003] To solve the above problems, the existing technology uses channel steel, I-beam and other section steel reinforcement instead of steel pipes, and cooperates with high-strength tensioning screw rods to form a non-perforated reinforcement system. Although this technology can improve the formwork turnover frequency and eliminate the hole repair process, it still has obvious limitations. First, the section steel components are fixed in size like steel sources, which has insufficient universality and cannot adapt to the construction needs of frame columns with different cross sections. It is necessary to customize multiple specifications of reinforcement or frequently replace components, which leads to low material turnover efficiency and high cost. Second, the section steel components need to be assembled piece by piece from all around the column body during installation, which makes it difficult for the operator to effectively implement component positioning and fastening operations in a space-limited working environment, and the construction efficiency is significantly reduced.

For the ordinary skilled in the art, the specific meaning of the above terms in the utility model can be understood according to the specific circumstances.

[0033] It should be noted that the features in the embodiments of the utility model can be combined with each other without conflict.

[0034] For example, the first and second embodiments can be combined with each other. Figures 1-5As shown, in order to solve the poor universality of the existing frame column formwork fixing structure, the inability to adapt to the construction requirements of frame columns with different cross sections, and the low installation efficiency, the embodiment provides a frame column formwork installation fixing structure, which comprises four pieces of formwork for enclosing a rectangular pouring, a back frame arranged at the outer side of the formwork at intervals, and a plurality of groups of rectangular reinforcing hoops 1 arranged at the outer side of the back frame and abutting against the back frame, the rectangular reinforcing hoop 1 comprising: two groups of first telescopic members 2 arranged in opposite parallel and having adjustable length, and two groups of second telescopic members 3 arranged in opposite parallel and having adjustable length, any one of the second telescopic members 3 being connected between the fixed ends of the two first telescopic members 2, and the other second telescopic member 3 being rotatably connected at one end to the telescopic end of any one of the first telescopic members 2 through a rotating member 4 and detachably connected at the other end to the telescopic end of the other first telescopic member 2 through a connecting member 6.

[0035] It should be noted that: the formwork can be a traditional wooden formwork, steel formwork, aluminum alloy formwork or plastic composite formwork, etc., and the specific material can be selected according to the actual situation, and the specifications of the back frame are also determined according to the actual specifications of the formwork, which are all prior art.

[0036] When the frame column formwork needs to be positioned and reinforced, the second telescopic member 3 is first rotated and unfolded through the rotating member 4 to make the rectangular reinforcing hoop 1 in a "C" shape opening state, the unfolded reinforcing hoop is sleeved outside the formwork, and then the second telescopic member 3 is rotated again and the rectangular reinforcing hoop 1 is closed through the connecting member 6, the length of the first and second telescopic members 3 is adjusted to adjust the size of the rectangular reinforcing hoop 1, so that the rectangular reinforcing hoop 1 is uniformly pressed on the four edges of the back frame of the frame column formwork with different cross-sectional sizes to form a closed rectangular constraint, without the need for customizing or frequently replacing the reinforcing members, which significantly improves the material turnover efficiency, reduces material waste and is convenient for storage and transportation, reduces the construction cost, improves the universality, and the setting of the rotating member 4 and the detachable connecting member 6 enables the rectangular reinforcing hoop 1 to be quickly unfolded or closed, which is especially suitable for installation work in narrow space, reduces the piece-by-piece assembly process, greatly improves the construction efficiency and reduces the labor cost; the present utility model directly abuts against the formwork back frame through the external reinforcing hoop, without the need for opening holes in the formwork to pull the screw rod, avoiding the problems of slurry leakage, mold expansion and hole repair in the later period, while increasing the contact area of the reinforcing member and the back frame, enhancing the overall rigidity and lateral pressure resistance of the formwork, and ensuring the quality of the concrete molding.

[0037] As Figure 1As shown, the first telescopic member 2 comprises a first reinforcing rod 7 which is telescopic and can abut against the back frame, a first adjusting rod 8 which is parallelly connected at the bottom of the first reinforcing rod 7 and is telescopic, a first locking assembly 9 which is arranged on the first reinforcing rod 7 and is used for locking the length of the first reinforcing rod 7, and a first limiting assembly 10 which is arranged on the first adjusting rod 8 and limits the extension of the first adjusting rod 8. The first adjusting rod 8 can be freely shortened, and the first adjusting rod 8 can be freely extended after the first limiting assembly 10 is released.

[0038] The second telescopic member 3 comprises a second reinforcing rod 11 which is the same as the first reinforcing rod 7, a second adjusting rod 12 which is parallelly connected at the top of the second reinforcing rod 11 and is the same as the first adjusting rod 8, a second locking assembly which is the same as the first locking assembly 9, and a second limiting assembly 13 which is the same as the first limiting assembly 10.

[0039] Any one of the second adjusting rods 12 is connected with the fixed ends of two first adjusting rods 8 respectively, and the other second adjusting rod 12 is rotatably connected with the telescopic end of any one of the first adjusting rods 8 through the rotating member 4 at one end and detachably connected with the telescopic end of the other first adjusting rod 8 through the connecting member 6 at the other end.

[0040] The specific principle of size adjustment of the rectangular reinforcing hoop 1 is as follows: before the rectangular reinforcing hoop 1 is installed, the telescopic lengths of the first reinforcing rod 7 (longitudinal) and the second reinforcing rod 11 (transverse) are adjusted first, so that the total length matches the actual cross-sectional size of the formwork column template, and the rigid support is ensured, then the telescopic lengths of the first adjusting rod 8 and the second adjusting rod 12 are adjusted to be slightly larger than the template size, the second telescopic part is expanded by rotating the rotating part 4, so that the rectangular reinforcing hoop 1 is in a "C" shape opening state, the expanded reinforcing hoop is sleeved outside the template, after the expanded reinforcing hoop is sleeved outside the template, the second telescopic part 3 is rotated again and the rectangular reinforcing hoop 1 is closed through the connecting part 6; the first telescopic part 2 and the second telescopic part 3 connected to each other are closely attached to the template, the operator manually pushes the second first telescopic part 2, so that a pushing force is applied to the second adjusting rod 12, the pushing force forces the second adjusting rod 12 to freely shorten in one direction, thereby making the second first telescopic part 2 move towards the template, and finally making the first reinforcing rod 7 closely attached to the back frame to form a longitudinal clamping force, then the second telescopic part 3 connected to the two first telescopic parts 2 is continuously pushed, the pushing force is transmitted to the first adjusting rod 8 of the two first telescopic parts 2, the pushing force makes the first adjusting rod 8 freely shorten in one direction, further drives the second telescopic part 3 to move towards the template, so that the second reinforcing rod 11 closely attached to the back frame forms a transverse clamping force, through the above linkage mechanism, the two first reinforcing rods 7 and the two second reinforcing rods 11 are finally uniformly pressed against the back frame of the four sides of the template, forming a closed rectangular constraint; when the concrete is poured, the swelling mold pushing force acts on the template, and then acts on the first fixed rod 15 and the second fixed rod 15, and finally acts on the first adjusting rod 8 and the second adjusting rod 12, the adjusting rod cannot be elongated due to the limitation of the limiting assembly, so as to ensure that the reinforcing rod maintains a constant pressing force and prevents the template from moving. If you want to remove the rectangular reinforcing hoop 1 from the template, the operator releases the limitation of the limiting assembly, and each adjusting rod can be freely elongated.

[0041] As shown in Figure 2 The first reinforcing rod 7 comprises: a fixed cylinder 14 which is hollow inside and has an open end, and a fixed rod 15 which is slidably connected inside the fixed cylinder 14, the fixed cylinder 14 and the fixed rod 15 are both rectangular, the side surface of the fixed cylinder 14 towards the template is open, and the side surface of the fixed rod 15 towards the template is flush with the side surface of the fixed cylinder 14.

[0042] The first locking assembly 9 comprises: a threaded hole 16 which is provided through the side wall of the fixed cylinder 14, and a locking nut 17 which is threadedly connected in the threaded hole 16 and has an end surface abutting against the outer surface of the fixed rod 15.

[0043] It should be noted that the first reinforcing rod 7 and the second reinforcing rod 11 have the same structure and the same working principle, so the working principle of the second reinforcing rod 11 will not be described again.

[0044] The first reinforcing rod 7 adjusts the length when sliding the fixed rod 15 out of or into the fixed cylinder 14, adjusts the total length of the reinforcing rod to adapt to the size of the formwork, and tightens the locking nut 17 after the length of the reinforcing rod is determined, so that the end of the nut abuts against the outer surface of the fixed rod 15 to achieve rigid fixation by using friction. The rectangular cross section of the fixed cylinder 14 and the fixed rod 15 is arranged to be flush with the side surface of the formwork on the side of the formwork, so that the side surface of the first reinforcing rod 7 can be in contact with the full width of the back frame to uniformly transmit pressure and avoid local deformation.

[0045] As shown in Figure 3 The first adjusting rod 8 includes an adjusting cylinder 18 which is hollow and open at one end, a movable rod 19 which is slidingly arranged in the adjusting cylinder 18, and adjusting notches 20 which are arranged on the side of the movable rod 19 away from the formwork and uniformly distributed along the length direction of the movable rod 19. The adjusting cylinder 18 is connected with the fixed cylinder 14, and the adjusting cylinder 18 does not contact the back frame when the side surface of the fixed cylinder 14 contacts the back frame.

[0046] As shown in Figures 4-5 The first limiting component 10 includes a clamping block 21 which is adapted to the adjusting notch 20 at one end and movably penetrates the outer side wall of the adjusting cylinder 18 on the side away from the formwork, a limiting block 22 which is arranged on the outer side wall of the adjusting cylinder 18 on the side away from the formwork, a cavity 23 which is arranged in the limiting block 22 and has an inner side wall slidingly connected with the clamping block 21, a pull rod 24 which is connected with the clamping block 21 at one end and penetrates the side wall of the cavity 23 on the side away from the clamping block 21, a spring 25 which is sleeved on the pull rod 24 and connected with the clamping block 21 at one end and the inner side wall of the cavity 23 at the other end, a horizontal rod 26 which is connected with the pull rod 24 perpendicularly and connected with a horizontal slot 27 which is arranged on the outer side wall of the limiting block 22 on the side away from the adjusting cylinder 18 and adapted to the horizontal rod 26. When the limiting spring 25 is in a natural state, the horizontal rod 26 is located in the horizontal slot 27.

[0047] The cross section of the adjusting notch 20 is a right-angled triangle, and the right-angled side is arranged towards the adjusting cylinder 18. The end of the clamping block 21 which penetrates into the adjusting notch 20 is provided with a bevel which is adapted to the clamping block 21.

[0048] It should be noted that the first adjusting rod 8 and the second adjusting rod 12 have the same structure and the same working principle, so the working principle of the second adjusting rod 12 will not be described again.

[0049] When the first adjusting rod 8 is length-adjusted: when the movable rod 19 is shortened by external force, the adjusting slot 20 moves into the adjusting cylinder 18 along with the movable rod 19, the inclined surface of the adjusting slot 20 is in contact with the inclined surface of the clamping block 21, the clamping block 21 is pushed to slide away from the movable rod 19, the compression spring 25 is compressed, and when the slot passes through the clamping block 21 completely, the spring 25 pushes the clamping block 21 to reset and re-clamp into the next slot, thereby realizing continuous shortening of the movable rod 19 and automatic locking of the clamping block 21 after each shortening; when the concrete is poured, the formwork expands outward under lateral pressure and tries to lengthen the adjusting rod, but the clamping block 21 cannot slide outward because the right-angled edge of the adjusting slot 20 is in abutment with the planar side of the clamping block 21, thereby forming a rigid block to prevent the adjusting rod from lengthening, ensuring that the fastening force of the reinforcing rod on the back frame is constant and avoiding constraint failure; when it is necessary to remove the rectangular reinforcing hoop 1 or lengthen the first adjusting rod 8, the operator pulls the pull rod 24 horizontally outward, which drives the clamping block 21 to disengage from the adjusting slot 20 and the horizontal rod 26 to disengage from the horizontal slot 27, after the clamping block 21 completely exits the slot, the pull rod 24 is rotated to make the horizontal rod 26 abut against the outer surface of the limiting block 22, thereby fixing the position of the clamping block 21, so that the movable rod 19 can be freely pulled out, and after being adjusted to the appropriate length, the pull rod 24 is pulled and rotated, so that the horizontal rod 26 is aligned with the horizontal slot 27, the spring 25 pushes the clamping block 21 to re-press into the current corresponding adjusting slot 20, and the position locking after lengthening is completed, which is simple in structure, convenient to operate and ensures the stability of the formwork reinforcing system.

[0050] In order to avoid force transmission interference and avoid the influence of the friction between the fixed rod 15 and the back frame on the movement of the adjusting rod, the adjusting cylinder 18 does not contact the back frame when the side surface of the fixed cylinder 14 contacts the back frame.

[0051] As shown in Figure 4 The rotating member 4 includes a first ear plate 28 connected to the telescopic end of the first adjusting rod 8, a second ear plate 29 connected to one end of the second adjusting rod 12, and a rotating shaft 30 vertically and rotatably connected between the first ear plate 28 and the second ear plate 29, and the connecting member 6 includes a first connecting plate 31 connected to the telescopic end of the other first adjusting rod 8, a second connecting plate 32 connected to the other end of the second adjusting rod 12, and a fixing bolt 33 for fixedly connecting the first connecting plate 31 and the second connecting plate 32.

[0052] The unfolding and closing principle of the rectangular reinforcing hoop 1 is that under the action of the rotating member 4 composed of the first ear plate 28, the second ear plate 29 and the rotating shaft 30, the second telescopic member is rotated and unfolded, the reinforcing hoop is in a "C" shape opening state, and the reinforcing hoop is conveniently sleeved to the outside of the formwork, the unfolded reinforcing hoop is sleeved to the outside of the formwork, when closed, the second telescopic member is rotated, the second connecting plate 32 at the other end of the second telescopic member is aligned with the first connecting plate 31 of the first telescopic member on the opposite side, and the fixed bolt 33 is inserted to complete the connection.

[0053] Finally, it is explained that the above examples are only to illustrate the technical solutions of the present application and are not limiting. Although the present application has been described by referring to the preferred embodiments of the present application, it should be understood by those skilled in the art that various changes can be made in form and details without departing from the spirit and scope of the present application as defined by the appended claims.
