Description

Technical Field

[0001] The invention relates to the technical field of building formwork, in particular to an adaptive formwork device suitable for casting beam-column nodes of a UHPC transformer substation. Background Art

[0002] UHPC (Ultra-High Performance Concrete) is ultra-high performance concrete. The compressive, tensile and flexural strength of UHPC far exceeds that of traditional concrete. UHPC also has high fluidity, low permeability and good workability, making it easy to achieve complex shapes and high-precision structural construction.

[0003] In the process of UHPC substation, in order to shorten the construction period, modular construction is usually adopted. The construction method of UHPC substation frame is to use prefabricated beams and prefabricated columns for construction. After the prefabricated beams and columns are installed, cement needs to be poured on the installation nodes. Before pouring cement, it is necessary to use templates to build a cavity for pouring cement at the node. In the process of prefabricating beams and columns, there will actually be certain dimensional errors. In the installation process of beams and columns, there will also be certain installation errors. The accumulated error will cause the center of the beams and columns to be unable to align after the beams and columns are installed, and there will be errors at the nodes of the beams and columns, so it is impossible to use templates with standard sizes to build the cement pouring cavity at the nodes. Summary of the invention

[0004] The purpose to be achieved by the present invention is to provide an adaptive formwork device suitable for casting beam-column nodes of UHPC substations, which solves the problem that the building formwork in the prior art cannot be applied to error nodes at beams and columns, and is suitable for beam and column nodes and can automatically adapt to node errors.

[0005] In order to achieve the above-mentioned purpose, the present invention adopts the following technical scheme: an adaptive formwork device suitable for casting beam-column nodes of UHPC substations, comprising a horizontal formwork assembly and a vertical formwork assembly for supporting nodes at beams and columns, the horizontal formwork assembly comprising two horizontal formworks arranged in a mirror image, the width direction of the two horizontal formworks being connected by a first telescopic member, the first telescopic member being suitable for telescoping so that the two horizontal formworks can move relative to each other in the width direction to fit on the beam, the vertical formwork assembly comprising two vertical formworks arranged in a mirror image, the width direction of the two vertical formworks being connected by a second telescopic member, the second telescopic member being suitable for telescoping so that the two vertical formworks can move relative to each other in the width direction to fit on the column, the two horizontal formworks are slidably connected to the vertical formworks so that the two horizontal formworks can fit on the beam while the two vertical formworks can fit on the column, the two horizontal formworks and the two vertical formworks enclose a casting cavity at the node of the beam and the column.

[0006] After adopting the above technical scheme, the present invention has the following advantages: through the adjustment of the first telescopic member and the second telescopic member, the horizontal template and the vertical template can be flexibly adjusted in the width direction to compensate for the size errors of the pre-fabricated beams and the size errors of the columns, so as to automatically adapt to beams and columns of different sizes; secondly, the two horizontal templates are slidably connected to the vertical templates to compensate for the installation errors at the nodes of the beams and the columns, so as to automatically adapt to the installation positions of the beams and the columns, so that the two horizontal templates can fit the beams while the two vertical templates can fit the columns, forming a casting cavity that adapts to the nodes of the beams and the columns, which can also reduce the on-site adjustment time and labor costs and speed up the construction progress.

[0007] Furthermore, the sliding direction of the horizontal template relative to the vertical template is parallel to the direction of relative movement of the two horizontal templates in the width direction.

[0008] By adopting the above-mentioned technical solution, the size and position of the beam can be adapted simultaneously by sliding the horizontal template relative to the vertical template and the relative movement of the two horizontal templates. The adjustment range is wider and the adjustment accuracy is more accurate, thereby better adapting to the size error of the beam and the installation error of the beam and the column.

[0009] Furthermore, the two vertical templates are provided with limiting parts which are arranged opposite to each other, and the two horizontal templates are located between the two limiting parts.

[0010] By adopting the above-mentioned technical solution, the two limiting parts limit the range of relative movement between the two horizontal templates and the sliding range of the horizontal template relative to the vertical template. The limiting parts can ensure that the horizontal template will not exceed the predetermined range during the adjustment process, effectively preventing excessive movement of the horizontal template, thereby maintaining the overall stability of the structure, and also ensuring that the size of the casting cavity meets the requirements, thereby improving the quality of the structure after casting.

[0011] Furthermore, each of the horizontal templates is provided with installation grooves and guide columns on different sides, and each of the vertical templates is provided with an installation slider sliding in the installation groove and a guide slider sliding in the guide column, and the sliding direction of the installation slider is consistent with the sliding direction of the guide slider.

[0012] By adopting the above-mentioned technical solution, the combination of the guide column and the guide slider and the combination of the mounting slider and the mounting groove provide dual support points. The mounting slider and the guide slider slide along the set direction, thereby enhancing the connection stability between the horizontal template and the vertical template, making the movement of the horizontal template relative to the vertical template more stable.

[0013] Furthermore, one end of the guide column is arranged on the transverse template, and the other end of the guide column is provided with a limit piece for cooperating with the transverse template to limit the sliding range of the guide slider.

[0014] By adopting the above-mentioned technical solution, the limiter can ensure that the guide slider slides within the correct range and prevent the guide slider from separating from the guide column, thereby improving the overall stability of the horizontal template and the vertical template.

[0015] Furthermore, the guide posts on the two transverse templates are arranged in mirror images with each other; or, at least two guide posts are arranged on the same side surface of each transverse template.

[0016] By adopting the above technical solution, the mirror-image arrangement of the guide columns helps to maintain the symmetry of the structure, helps to ensure the balance of the cross formwork, and reduces the risk of deflection; and / or, arranging multiple guide columns on the same side can increase the number of support points, improve the stability of the cross formwork, better disperse the load, improve the weight-bearing capacity of the cross formwork, and help reduce the deviation of the cross formwork during sliding.

[0017] Furthermore, the two vertical templates are provided with an adjustment mechanism for adjusting and locking the relative position between the two vertical templates along the telescopic direction of the second telescopic member.

[0018] By adopting the above technical solution, the adjustment mechanism allows workers to accurately adjust the distance between the two vertical formworks to ensure a close fit between the vertical formworks and the columns. The locking function can prevent the vertical formworks from moving during the pouring process to ensure the structural stability of the adaptive formwork device.

[0019] Furthermore, the two vertical templates are each provided with a clamping jaw, and the clamping jaws are threadedly connected via a threaded rod, and the rotational movement of the threaded rod drives the clamping jaws to move away from or toward each other, so that the two vertical templates can move relative to each other.

[0020] By adopting the above technical solution, the distance between the two vertical formworks can be accurately adjusted by rotating the threaded rod to ensure a tight fit between the vertical formworks and the columns. The mechanical locking effect of the threaded rod can ensure that the vertical formworks will not move during the pouring process. The design of the threaded rod makes the calibration process more intuitive and simple.

[0021] Furthermore, an elastic member is sleeved on the guide column, and two ends of the elastic member contact the transverse template and the guide slider. The elastic rebound force of the elastic member enables the transverse template to fit the crossbeam.

[0022] By adopting the above technical solution, since the vertical formwork is locked by the adjustment mechanism after adjustment, the elastic part can automatically adjust according to the gap between the beam and the horizontal formwork, ensuring that the horizontal formwork always fits tightly to the beam and can maintain a good fit even if it is slightly disturbed during construction. Workers do not need to manually adjust the position of the horizontal formwork continuously, which reduces the operating steps and simplifies the construction process.

[0023] Furthermore, the first telescopic member and the second telescopic member are elastic strips, the two vertical templates are bonded together by the elastic strips, and the two horizontal templates are bonded together by the elastic strips.

[0024] By adopting the above technical solution, the elastic strip can automatically compress or stretch according to the actual size changes of the beams and columns, so that the horizontal formwork and the vertical formwork can adapt to errors of different sizes. The elastic strip is easy to replace after being damaged, which simplifies the maintenance process. The elastic strip can also make the two horizontal formworks and the two vertical formworks sealed, effectively preventing cement from overflowing from the joints. BRIEF DESCRIPTION OF THE DRAWINGS

[0046] The technical solution of the present invention is described in detail with specific embodiments below. The following specific embodiments can be combined or replaced with each other according to actual conditions, and the same or similar concepts or processes may not be described in detail in some embodiments.

[0047] like Figures 1 to 14 As shown, the present invention provides an adaptive formwork device suitable for casting beam-column nodes of UHPC substations, comprising a horizontal formwork assembly and a vertical formwork assembly for supporting nodes at the horizontal beam 100 and the column 200, the horizontal formwork assembly comprising two horizontal formworks 300 arranged in a mirror image, the width direction of the two horizontal formworks 300 being connected by a first telescopic member 500, the first telescopic member 500 being adapted to telescope so that the two horizontal formworks 300 can move relatively in the width direction to fit on the horizontal beam 100, and the vertical formwork assembly comprising two vertical formworks arranged in a mirror image The template 400, the two vertical templates 400 are connected in the width direction by a second telescopic member 600, and the second telescopic member 600 is suitable for telescoping so that the two vertical templates 400 can move relatively in the width direction to fit on the column 200, and the two horizontal templates 300 are slidably connected to the vertical template 400, so that the two horizontal templates 300 fit the beam 100 while the two vertical templates 400 can fit the column 200, and the two horizontal templates 300 and the two vertical templates 400 enclose to form a casting cavity at the node of the beam 100 and the column 200.

[0048] Through the adjustment of the first telescopic member 500 and the second telescopic member 600, the horizontal template 300 and the vertical template 400 can be flexibly adjusted in the width direction to compensate for the size errors of the pre-fabricated beams 100 and the size errors of the columns 200, so as to automatically adapt to beams 100 and columns 200 of different sizes. Secondly, the two horizontal templates 300 are slidably connected to the vertical template 400 to compensate for the installation errors at the nodes of the beams 100 and the columns 200, so as to automatically adapt to the installation positions of the beams 100 and the columns 200, so that the two horizontal templates 300 can fit the beams 100 while the two vertical templates 400 can fit the columns 200, forming a casting cavity adapted to the nodes of the beams 100 and the columns 200, which can also reduce the on-site adjustment time and labor costs and speed up the construction progress.

[0049] It should be noted that the cross beam 100 is usually arranged horizontally, the column 200 is usually arranged vertically, and the cross template 300 includes two parts: a bottom part for supporting the bottom surface of the cross beam 100 and a side part for supporting other side surfaces of the cross beam 100 .

[0050] The two vertical formworks 400 are provided with an adjustment mechanism for adjusting and locking the relative position between the two vertical formworks 400 along the telescopic direction of the second telescopic member 600. The adjustment mechanism allows workers to accurately adjust the distance between the two vertical formworks 400 to ensure a close fit between the vertical formworks 400 and the columns 200. The locking function can prevent the vertical formworks 400 from moving during the pouring process to ensure the structural stability of the adaptive formwork device.

[0051] Specifically, the two vertical templates 400 are each provided with a clamping jaw 450, and the clamping jaws 450 are threadedly connected by a threaded rod 460. The rotation of the threaded rod 460 drives the clamping jaws 450 to move away from or toward each other, so that the two vertical templates 400 can move relative to each other. By rotating the threaded rod 460, the distance between the two vertical templates 400 can be accurately adjusted to ensure that the vertical templates 400 and the column 200 are tightly fitted. The mechanical locking effect of the threaded rod 460 can ensure that the vertical template 400 will not move during the pouring process. The design of the threaded rod 460 makes the calibration process more intuitive and simple. In order to facilitate operation, a rocker 470 is provided on the threaded rod 460 to facilitate operation.

[0052] Since the size error and installation error of the beam 100 and the column 200 are relatively small, and the spacing of the vertical formwork 400 after adjustment is fixed, the two vertical formworks 400 are provided with relatively arranged limit parts 410, and the two horizontal formworks 300 are located between the two limit parts 410. The two limit parts 410 are used to limit the range of relative movement between the two horizontal formworks 300 and the sliding range of the horizontal formworks 300 relative to the vertical formworks 400. The limit parts 410 can ensure that the horizontal formworks 300 will not exceed the predetermined range during the adjustment process, effectively preventing the excessive movement of the horizontal formworks 300, thereby maintaining the overall stability of the structure, and can also ensure that the size of the casting cavity meets the requirements, thereby improving the quality of the structure after casting.

[0053] In order to improve the adjustment accuracy, the sliding direction of the horizontal template 300 relative to the vertical template 400 is parallel to the direction of relative movement of the two horizontal templates 300 in the width direction, that is, the horizontal template 300 moves relative to the vertical template 400 along the width direction of the horizontal template 300. Therefore, the size and position of the beam 100 can be adapted at the same time through the sliding of the horizontal template 300 relative to the vertical template 400 and the relative movement of the two horizontal templates 300, the adjustment range is wider, the adjustment accuracy is more accurate, and the size error of the beam 100 and the installation error of the beam 100 and the column 200 can be better adapted.

[0054] Each horizontal template 300 is provided with a mounting groove 310 and a guide column 320 on different sides. The guide column 320 is assembled on the horizontal template 300 through a guide column seat 340. The horizontal template 300 is provided with a mounting seat 330. The mounting seat 330 is provided with a mounting groove 310. Each vertical template 400 is provided with a mounting slider 420 that slides on the mounting groove 310 and a guide slider 430 that slides on the guide column 320. The sliding direction of the mounting slider 420 is consistent with the sliding direction of the guide slider 430. The combination of the guide column 320 and the guide slider 430 and the combination of the mounting slider 420 and the mounting groove 310 provide dual support points. The mounting slider 420 and the guide slider 430 slide along the set direction, which enhances the connection stability between the horizontal template 300 and the vertical template 400, and makes the movement of the horizontal template 300 relative to the vertical template 400 more stable.

[0055] Furthermore, one end of the guide column 320 is arranged on the horizontal template 300, and the other end of the guide column 320 is provided with a limit piece 440, which is used to cooperate with the horizontal template 300 to limit the sliding range of the guide slider 430. The limit piece 440 can ensure that the guide slider 430 slides within the correct range and prevent the guide slider 430 from detaching from the guide column 320, thereby improving the overall stability of the horizontal template 300 and the vertical template 400.

[0056] In order to make the transverse formwork 300 move more smoothly, at least two guide columns 320 are provided on the same side surface of each transverse formwork 300. Providing multiple guide columns 320 on the same side can increase the number of support points, improve the stability of the transverse formwork 300, better disperse the load, improve the weight-bearing capacity of the transverse formwork 300, and help reduce the deviation of the transverse formwork 300 during the sliding process.

[0057] Preferably, two guide columns 320 are provided, and the two guide columns 320 are located on the sides of the transverse template 300 and arranged in the vertical direction. The guide columns 320 on the two transverse templates 300 are mirrored to each other. The mirrored arrangement of the guide columns 320 helps to maintain the symmetry of the structure, helps to ensure the balance of the transverse template 300, and reduces the risk of deflection. In addition, the mounting groove 310 is located at the bottom of the transverse template 300 to form multi-point support for the transverse template 300.

[0058] In order to further realize automatic adjustment, an elastic member 350 is sleeved on the guide column 320, and both ends of the elastic member 350 contact the cross template 300 and the guide slider 430. The elastic rebound force of the elastic member 350 is to make the cross template 300 fit the beam 100. The elastic member 350 can automatically adjust according to the gap between the beam 100 and the cross template 300 to ensure that the cross template 300 always fits tightly against the beam 100, and can maintain a good fit even if it is slightly disturbed during the construction process. Workers do not need to manually adjust the position of the cross template 300 continuously, which reduces the operating steps and simplifies the construction process.

[0059] Among them, the first telescopic member 500 and the second telescopic member 600 are elastic strips, and the two vertical templates 400 are bonded together by the elastic strips, and the two horizontal templates 300 are bonded together by the elastic strips. The elastic strips can automatically compress or stretch according to the actual size changes of the beam 100 and the column 200, so that the horizontal template 300 and the vertical template 400 can adapt to errors of different sizes. The elastic strips are easy to replace after being damaged, which simplifies the maintenance process. The elastic strips can also make the two horizontal templates 300 and the two vertical templates 400 sealed and connected, effectively preventing cement from overflowing from the connection.

[0060] When assembling the adaptive formwork device, Figure 1 and Figure 2 As shown, the guide post 320 is assembled with the guide post seat 340. After the assembly, the guide post seat 340 is fixed on the horizontal template 300, and the mounting seat 330 with the mounting groove 310 is fixed on the horizontal template 300. The mounting slider 420 and the guide slider 430 are respectively fixed on the vertical template 400. Then, as shown in FIG. Figure 3 and Figure 4 As shown, the installation slider 420 is assembled with the installation groove 310, and the guide slider 430 is assembled with the guide column 320, so that the horizontal template 300 can slide along the direction of the guide column 320. Figure 5 and Figure 6 As shown, assemble the horizontal template 300 and the vertical template 400 on the other side. The horizontal templates 300 and the vertical templates 400 on both sides are connected by the first telescopic member 500 and the second telescopic member 600 respectively. The width of the first telescopic member 500 is C, and the width of the second telescopic member 600 is D. The thickness of C and D is determined by the actual compression stroke, and A and B are the sliding strokes of the horizontal template 300 and the vertical template 400. Figure 7 FIG. 2 is a front view of the node between the beam 100 and the column 200. Figure 8 The figure shows a top view of the node of the beam 100 and the column 200. The width of the beam 100 is H, and the width of the column 200 is L. E and F are the distances from the edge of the beam 100 to the edge of the column 200 after the beam 100 and the column 200 are installed and fixed.

[0061] like Fig. 9 and Fig.10 As shown, the clamping jaws 450 clamp the vertical template 400, and the rocker 470 is rotated to tighten the clamping jaws 450, so that the vertical template 400 is fastened to the column 200. The elastic member 350 presses inwardly on the horizontal template 300, and the horizontal template 300 is always attached to the beam 100 due to the inward pressure of the elastic member 350.

[0062] like Fig.11 As shown, when the centers of the cross beam 100 and the column 200 are not aligned, the center of the cross beam 100 is offset in the direction of D. The distance D decreases, and the distance F increases. The inner surfaces of the cross template 300 and the vertical template 400 always fit the cross beam 100 and the column 200. The travel distance A of the cross template 300 decreases, and the travel distance B of the cross template 300 increases. The elastic clamp is pressed on the cross template 300, and the cross template 300 is subjected to the inward pressure of the elastic member 350, so that the cross template 300 and the cross beam 100 always keep in contact.

[0063] like Fig.12 As shown, when the centers of the cross beam 100 and the column 200 are not aligned, the center of the cross beam 100 is offset in the F direction. The distance F becomes smaller, and the relative distance E becomes larger. The inner surfaces of the horizontal template 300 and the vertical template 400 are always in contact with the cross beam 100 and the column 200. The B stroke of the template becomes smaller, and the A stroke becomes larger. The elastic member 350 is pressed on the cross template 300, and the cross template 300 is subjected to the inward pressure of the elastic member 350, so that the cross template 300 and the cross beam 100 are always in contact.

[0064] like Fig.13 As shown, the transverse template 300 is subjected to the inward pressure of the elastic member 350, so that the transverse template 300 and the crossbeam 100 always keep in contact. C is the width of the first telescopic member 500, and the first telescopic member 500 is always in a compressed state. When the width H increases, the compression of the first telescopic member 500 decreases, the width of C increases, the distance between A and B decreases, and the distance between E and F decreases; when the width H decreases, the width of C decreases, the distance between A and B increases, and the distance between E and F increases.

[0065] like Fig.14 As shown, the vertical template 400 is fastened to the column 200 by the clamping claw 450. The second telescopic member 600 is always in a compressed state. When the width of L increases, the compression amount of the second telescopic member 600 decreases, the width of D increases, the distance between E and F decreases, and the distance between A and B increases.

[0066] It can be understood that in other embodiments, the horizontal template can also be moved relative to the length direction of the vertical template to adapt to the installation error of the horizontal template and the vertical template in the vertical direction.

[0067] It is understandable that in other embodiments, the guide posts may be provided in number of three, four, etc. to form multiple supports, and a corresponding number of elastic members may be provided accordingly.

[0068] It can be understood that in other embodiments, the first telescopic member and the second telescopic member may also be sponge strips or the like.

[0069] In addition to the above-mentioned preferred embodiments, the present invention also has other implementation modes. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative work are within the scope of protection requested by the present invention.
