Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a template supporting device for a polygonal concrete column. Background Art

[0002] Concrete formwork is a device used to provide temporary support and fixation for concrete structures. During the concrete pouring process, the formwork can effectively support the concrete to form the desired shape and structure. Through reasonable construction steps and installation of the formwork, the stability and quality of the concrete structure can be ensured.

[0003] Support formwork can be used in the fields of bridge construction, water conservancy and hydropower construction, house construction, etc. For example, in bridge construction, support formwork is used to support the construction of reinforced concrete bridges to ensure the safety and accuracy of the construction process. In existing concrete buildings, the support formwork must first be formed into a building frame, and then concrete is poured into the support formwork. If the support formwork is not well fastened, it is easy to cause the concrete to be pushed open and cause pouring failure.

[0004] In different fields, when polygonal column concrete is supported, the existing support formwork cannot guarantee effective support and connection, and the single support formwork is not convenient for quick adjustment to adapt to different polygonal concrete sizes. Summary of the invention

[0005] The utility model aims to provide a template supporting device for a polygonal concrete column, which has a simple and compact structure and can realize the supporting of polygonal concrete column templates. The length can be quickly adjusted and the device is suitable for concrete column templates with different polygons.

[0006] To achieve the above purpose, the formwork support device for a polygonal concrete column comprises:

[0007] The number of supporting components in the same layer is the same as the number of sides of the concrete column, and each group of supporting components has a fixing block and an adjusting plate;

[0008] The fixed block is provided with a groove group arranged along the length direction thereof;

[0009] A pair of adjustment plates slide symmetrically on the fixed block, and the adjustment plates are fixed by positioning rods passing through the slot group;

[0010] A corner component is located between adjacent supporting components and is consistent with the corner of the concrete column, and has a first supporting block and a second supporting block that are rotatably connected to each other;

[0011] The first support block is connected to one of its supporting components, and the second support block is connected to another supporting component.

[0012] In some embodiments, the slot set has a plurality of through positioning holes;

[0013] A plurality of positioning holes are arranged side by side along the length direction of the fixing block;

[0014] The positioning rod passes through the adjustment plate and the positioning hole and is fixed by a locking nut.

[0015] Furthermore, the slot group also has strip-shaped slots;

[0016] The center of the strip groove is consistent with the center of the positioning hole, and the width is smaller than the diameter of the positioning hole;

[0017] The positioning rod has a pair of cutouts on its outer diameter to enable the positioning rod to slide in the strip groove.

[0018] In some embodiments, the adjustment plate is a pair of support plates correspondingly located above and below the fixed block;

[0019] A pair of support plates are connected to each other via a connecting plate at one side away from the fixed block, and each support plate is flush with a side of the fixed block facing the support template.

[0020] Furthermore, the fixing block is provided with a limiting sliding groove arranged along its length direction;

[0021] A limiting block is arranged on the support plate and is arranged in the limiting sliding groove for relative sliding.

[0022] In some embodiments, a mounting block with a vertical axis is provided on the end side of the adjustment plate away from the fixing block;

[0023] The mounting block is provided with a through hole;

[0024] The rod body of the spiral rod passes through the through hole and the corner component and is locked and fixed by a nut.

[0025] Furthermore, the first supporting block and the second supporting block are both L-shaped structures, and the side close to the supporting formwork is flush with the side of the fixed block close to the supporting formwork.

[0026] In some embodiments, a connecting rod is provided between adjacent supporting components of the upper and lower layers;

[0027] The upper end of the connecting rod passes through the middle position of the upper fixed block slot group, and the lower end passes through the middle position of the lower fixed block slot group, and both are locked and fixed by a pair of nuts located at the upper and lower ends of the fixed blocks.

[0028] Compared with the prior art, the present invention is a device for supporting a polygonal concrete column formwork, which is connected between adjacent supporting parts through corner parts, and the adjusting plates in each group of supporting parts slide symmetrically on the fixing blocks and are locked and fixed, which not only realizes the support of the polygonal concrete column formwork, but also realizes the quick adjustment of the length, and is suitable for concrete column formworks with different sides;

[0029] Since the groove group includes strip grooves and positioning holes, when a pair of cutouts on the positioning rod are parallel to the strip grooves, the adjustment plate can move on the fixed block. When the cutouts and the strip grooves are rotated and staggered, the adjustment plate is positioned on the fixed block, thereby realizing rapid movement and locking of the adjustment plate on the fixed block, which is suitable for concrete column templates of different sizes and is more convenient and flexible to operate;

[0030] Since the adjustment plate has a pair of support plates arranged up and down and connected by a connecting plate, each support plate is flush with the side of the fixed block facing the support formwork. Therefore, when supporting concrete columns of different sizes, the side of the support component close to the concrete column is always in contact with the support formwork, which can increase the contact area with the support formwork and support the support formwork more evenly.

[0031] Since connecting rods are provided between the upper and lower adjacent supporting components, the connecting rods pass through the middle position of the fixed block slot group and are then fastened and fixed by nuts, the support of the supporting formwork by the multi-layer supporting components is achieved, effectively ensuring the overall stability.

[0043] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0044] like Figure 1 , Figure 2 , Figure 3 As shown, the formwork support device for the polygonal concrete column comprises:

[0045] The number of supporting components 30 in the same layer is the same as the number of sides of the concrete column 11, and each group of supporting components 30 has a fixing block 31 and an adjusting plate 32;

[0046] The fixing block 31 is provided with a groove group arranged along its length direction;

[0047] A pair of adjustment plates 32 slide symmetrically on the fixed block 31, and the adjustment plates 32 are fixed by the positioning rod 50 passing through the groove group;

[0048] The corner component 20 is located between adjacent supporting components 30 and has a first supporting block 21 and a second supporting block 22 that are rotatably connected to each other;

[0049] The first support block 21 is connected to its supporting component 30, and the second support block 22 is connected to another supporting component 30;

[0050] Specifically, a support formwork 12 is provided on the circumference of the concrete column 11, and the support formwork 12 is used to support the concrete to form a desired shape and structure;

[0051] The number of supporting components 30 per layer is determined according to the number of sides of the concrete column 11 before installation. For example, when the concrete column is a hexagonal column, there are six groups of supporting components 30 at the same layer (height); each group of supporting components 30 has a fixed block 31 and a pair of adjustment plates 32, and the adjustment plates 32 slide symmetrically on the fixed block 31;

[0052] The corner component 20 is used to connect adjacent supporting components 30. The first supporting block 21 and the second supporting block 22 can be rotatably connected to each other through the supporting shaft 23, and the angle is 0-180° to be suitable for concrete columns 11 with different polygons;

[0053] When the formwork support device for the polygonal concrete column is used, Figures 1 to 3As shown, taking the pentagonal column concrete as an example, the corresponding supporting template 12 is laid according to the polygonal concrete column 11, and the length of the supporting component 30 is adjusted to match each other, that is, a pair of adjustment plates 32 are correspondingly moved to appropriate positions on the fixing block 31, and the positioning rod 50 passes through the through hole on the adjustment plate 32 and the groove group on the fixing block 31 so that the adjustment plate 32 is limited and fixed on the fixing block 31;

[0054] The corner components 20 are placed between adjacent supporting components 30 and connected accordingly. Finally, five groups of supporting components 30 and the corner components 20 therebetween are connected to each other, and the pentagonal concrete column formwork is supported and fixed accordingly.

[0055] like Figure 3 , Figure 4 , Figure 5 As shown, as an embodiment of the present utility model, the slot group has a plurality of penetrating positioning holes 313;

[0056] A plurality of positioning holes 313 are arranged side by side along the length direction of the fixing block 31;

[0057] The positioning rod 50 passes through the adjustment plate 32 and the positioning hole 313 and is fixed by the locking nut 52;

[0058] Furthermore, the slot group also has a strip-shaped slot 312;

[0059] The center of the strip groove 312 is consistent with the center of the positioning hole 313, and the width is smaller than the diameter of the positioning hole 313;

[0060] The positioning rod 50 has a pair of cutouts 51 on its outer diameter to allow the positioning rod 50 to slide in the strip groove 312;

[0061] Specifically, the plurality of positioning holes 313 are arranged along the length direction of the fixing block 31;

[0062] When the adjustment plate 32 moves to a suitable position on the fixing block 31, the positioning rod 50 passes through the adjustment plate 32 and the positioning hole 313 to fix the adjustment plate 32. Although this method realizes the positioning of the adjustment plate 32, there are the following problems: when the position of the adjustment plate 32 is improper and needs to be adjusted in time, that is, the positioning rod 50 does not match one of the positioning holes 313 properly and other positioning holes 313 need to be adjusted, the locking nut 52 needs to be unscrewed first, and then the positioning rod 50 is pulled out and inserted into the positioning hole 313 at other positions, so it is impossible to adjust quickly;

[0063] In this embodiment, the width of the strip groove 312 is smaller than the diameter of the positioning hole 313, and the positioning rod 50 is provided with a pair of cutouts 51 smaller than the width of the strip groove 312. When the cutouts 51 and the strip groove 312 are parallel to each other, the positioning rod 50 can move in the strip groove 312.

[0064] Specifically, when the position of the adjustment plate 32 is improper and needs to be adjusted in time, loosen the locking nut 52 for a while, rotate the positioning rod 50, so that the cutout 51 on the positioning rod 50 is parallel to the strip groove 312, and the positioning rod 50 can move directly in the strip groove 312, driving the adjustment plate 32 to move on the fixed block 31, and when the positioning rod 50 moves to the appropriate position, the positioning rod 50 is located at one of the positioning holes 313 and rotates, staggering the cutout 51 and the strip groove 312, and then tightening the locking nut 52. Therefore, without the need to completely unscrew the locking nut 52 and pull out and insert the positioning rod 50, the movement and locking of the adjustment plate 32 on the fixed block 31 are realized, thereby realizing rapid adjustment of concrete columns 11 of different sizes, and at the same time ensuring the support and fixation of the support formwork 12 by the support component 30.

[0065] like Figure 3 , Figure 4 , Figure 5 As shown, in some embodiments, the adjustment plate 32 is a pair of support plates correspondingly located above and below the fixing block 31;

[0066] A pair of support plates are connected to each other via a connecting plate 322 at one side away from the fixing block 31, and each support plate is flush with a side of the fixing block 31 facing the supporting template 12;

[0067] Furthermore, the fixing block 31 is provided with a limiting sliding groove 311 arranged along its length direction;

[0068] The support plate is provided with a limiting block 321 which is located in the limiting sliding groove 311 and slides relatively;

[0069] Specifically, the adjustment plate 32 has a pair of support plates arranged up and down and connected by a connecting plate 322. Each support plate is flush with the side of the fixing block 31 facing the support form 12. The purpose is that when supporting concrete columns 11 of different sizes, the side of the supporting component 30 close to the concrete column 11 is always in contact with the support form 12, which can increase the contact area with the support form 12 and support the support form 12 more evenly.

[0070] The limiting block 321 on the adjusting plate 32 matches the limiting sliding groove 311 on the fixing block 31 , so as to ensure the lateral movement of the adjusting plate 32 on the fixing block 31 .

[0071] like Figure 4 As shown, in some embodiments, a mounting block 33 with a vertical axis is provided on the end side of the adjustment plate 32 away from the fixing block 31;

[0072] The mounting block 33 is provided with a through hole;

[0073] The rod body of the spiral rod 40 passes through the through hole and the corner component 20 and is locked and fixed by a nut;

[0074] like Figure 6 As shown, further, both the first support block 21 and the second support block 22 are L-shaped structures, and the side close to the supporting template 12 is flush with the side of the fixing block 31 close to the supporting template 12 .

[0075] Specifically, the mounting block 33 is arranged to rotate so that the angle of the spiral rod 40 can be adjusted to match different mounting positions;

[0076] The first support block 21 and the second support block 22 are both L-shaped structures, and can fit the support template 12 at the corner position while ensuring the installation of the spiral rod 40;

[0077] Taking the pentagonal concrete column 11 as an example, one of the spiral rods 40 is adjusted in angle through the mounting block 33 on one of the supporting components 30, and is fixed by passing through the first supporting block 21, and another spiral rod 40 is adjusted in angle through the mounting block 33 on another supporting component 30, and is fixed by passing through the second supporting block 22, and the first supporting block 21 and the second supporting block 22 are relatively rotated through the support shaft 23, and the angle between them is 108° and they are fitted and fixed to the supporting formwork 12.

[0078] In some embodiments, a connecting rod is provided between the upper and lower adjacent supporting members 30;

[0079] The upper end of the connecting rod passes through the middle position of the slot group of the upper fixed block 31, and the lower end passes through the middle position of the slot group of the lower fixed block 31, and both are locked and fixed by a pair of nuts located at the upper and lower ends of the fixed block 31;

[0080] In this embodiment, the concrete column 11 needs to be supported by multiple layers of supporting components 30, that is, the upper and lower layers of adjacent supporting components 30 are connected by connecting rods to ensure overall stability;

[0081] The connecting rod passes through the middle position of the groove group of the fixing block 31, that is, the middle positioning hole 313, and is then locked and fixed by a nut;

[0082] When the formwork support device for a polygonal concrete column is used, the formwork 12 and the wood block are sealed on the construction column according to the actual construction requirements and the size of the construction column (concrete column 11), and the construction column is reinforced by means of steel bars, tension bolts, etc., and then the formwork support device for a polygonal concrete column is installed according to the requirements of the special construction plan;

[0083] The support is installed every 1m from the bottom of the column, and the support component 30 is adjusted according to the size of the construction column, that is, the positioning rod 50 is rotated so that the cutout 51 on the positioning rod 50 is parallel to the strip groove 312. At this time, the positioning rod 50 is directly moved in the strip groove 312 and the adjustment plate 32 is directly moved on the fixed block 31. When it moves to a suitable position, the positioning rod 50 is located at one of the positioning holes 313 and rotated to stagger the cutout 51 and the strip groove 312, and then the locking nut 52 is tightened to complete the length adjustment of the support component 30;

[0084] The corner component 20 is placed between adjacent supporting components 30, and one spiral rod 40 is adjusted in angle through the mounting block 33 on one supporting component 30, and is fixed by a nut through the first supporting block 21, and another spiral rod 40 is adjusted in angle through the mounting block 33 on another supporting component 30, and is fixed by a nut through the second supporting block 22, and multiple groups of supporting components 30 and corner components 20 are used to support and fix the supporting formwork 12, and finally the supporting of one layer of supporting formwork 12 is completed;

[0085] The construction column requires multi-layer support, that is, the upper and lower adjacent support components 30 are connected by connecting rods, the connecting rods pass through the middle position of the fixed block 31 slot group, and then are locked and fixed by nuts to complete the fixation of the upper fixed block 31, and then the support of a layer of support formwork 12 is completed according to the above steps.
