Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of prefabricated beam templates, in particular to an adjustable support component and a template system. Background Art
[0002] Precast beams are prefabricated in a factory and then transported to the construction site for installation and fixation according to the design requirements. During precast beam construction, the primary method for removing the formwork is by rotating the formwork around a fixed hinge point. The formwork's spatial position differs between the working and open positions, and the transition between the working and open positions requires fine-tuning of the formwork's spatial position using support components.
[0003] The existing support assembly adopts a structure in which a part of the support rod is designed to be a guide post and a guide sleeve that cooperate with each other. The guide post slides in the guide sleeve and the guide post and the guide sleeve are locked by a pin to adapt to the support of the template in the working state and the open state. Figures 1 to 3 and Figure 7 As shown, the existing guide post and guide sleeve structure has its overlap position in the middle of the support assembly. In order to ensure smooth extension and retraction of the support assembly, the guide post and the guide sleeve must overlap for a certain length, and the fitting gap between the two cannot be too large. Otherwise, it is easy to cause the guide post and the guide sleeve to self-lock due to the generation of a fold angle, affecting the use, and a guide sliding structure needs to be provided on the outer side of the guide post.
[0004] Therefore, the structure of the guide pin and guide sleeve of the existing support assembly is relatively complex, the processing requirements are high, and the basic length of the guide pin and guide sleeve is relatively long, which is not conducive to arrangement in some locations with small installation space. Utility Model Content
[0005] In view of this, the utility model provides an adjustable support assembly and template system with a simple structure, a smooth adjustment process, low processing precision requirements, and a short basic length of the guide column and guide sleeve, which is conducive to saving costs and being arranged in some locations with smaller installation space.
[0006] To achieve the above objectives:
[0007] The utility model provides an adjustable support assembly, comprising a first support member, a second support member and an adjustment assembly; wherein, one end of the first support member is used to rotate the connecting template, and one end of the second support member is used to fix the connecting bracket; the first end of the adjustment assembly is connected to the first support member, and the second end of the adjustment assembly is slidably provided on the second support member; the adjustment assembly is used to adjust the distance between the opposite ends of the first support member and the second support member.
[0008] In one embodiment, the adjustment assembly includes an adjustment unit and a sliding portion, wherein both ends of the adjustment unit are movably connected to the first support member and the sliding portion respectively, and the sliding portion is slidably arranged in the second support member, and a reserved gap is provided between the outer surface of the sliding portion and the inner surface of the second support member along the transverse direction of the template.
[0009] In one embodiment, the second support member is a guide sleeve structure, and the sliding portion is a guide post structure slidably disposed in the guide sleeve structure.
[0010] In one embodiment, the guide sleeve and the guide column structure are fixed to each other by a pin.
[0011] In one embodiment, the adjusting unit includes a screw, an adjusting member sleeved on the screw, and fixing nuts sleeved on both ends of the screw; wherein, the fixing nut fixes the two ends of the screw to the first support member and the sliding part respectively, and the adjusting member is used to rotate the screw to adjust the overlap length between the screw and the first support member and the sliding part respectively.
[0012] In one embodiment, the first support member is a columnar structure, and one end of the columnar structure is provided with a hinge plate for being hinged to the template.
[0013] In one embodiment, a reinforcing plate structure for connecting to the bracket is provided on one side of the second support member.
[0014] Based on the same concept as the aforementioned utility model, the present utility model also provides a template system, which includes a template and a bracket. The template system is provided with an adjustable support assembly as mentioned above, one end of the first support member is rotatably connected to the template, and one end of the second support member is fixedly connected to the bracket.
[0015] The adjustable support assembly and template system provided by the present invention have the second support member directly fixedly connected to the bracket, and the adjustment assembly is slidably connected to the second support member. The part of the adjustable support assembly that needs to be overlapped is set at a position close to the bracket.

Whether there is an angle between the adjustment assembly and the second support member does not affect the working process of the adjustable support assembly. The sliding fit between the adjustment assembly and the second support member does not require a longer overlap length and a smaller fit gap. Therefore, compared with the existing technology, the adjustable support assembly and template system provided by this application have a simpler structure, a smoother adjustment process, no self-locking and jamming problems, low processing accuracy requirements, and a shorter basic length of the guide column and guide sleeve, which is more conducive to cost saving and arrangement in some locations with smaller installation space.

[0030] like Figures 4 to 6 As shown, an embodiment of the present application provides an adjustable support assembly, including a first support member 10, a second support member 20 and an adjustment assembly 30; wherein, one end of the first support member 10 is used to rotate the connecting template 100, and one end of the second support member 20 is used to fix the connecting bracket 200; the first end of the adjustment assembly 30 is connected to the first support member 10, and the second end of the adjustment assembly 30 is slidably provided on the second support member 20; the adjustment assembly 30 is used to adjust the distance between the relative ends of the first support member 10 and the second support member 20.
[0031] The adjustable support assembly provided in the embodiment of the present application has a first support member 10 rotatably connected to the template 100, a second support member 20 directly fixedly connected to the bracket 200, and an adjustment assembly 30 slidably connected to the second support member 20. The part of the adjustable support assembly that needs to be overlapped is set at a position close to the bracket 200. The adjustment assembly 30 and the second support member 20 can be connected by fasteners such as pins. Whether there is an angle between the adjustment assembly 30 and the second support member 20 does not affect the working process of the adjustable support assembly. The sliding fit between the adjustment assembly 30 and the second support member 20 does not require a longer overlap length and a smaller fit gap. Therefore, compared with the prior art, the adjustable support assembly and template system provided in the embodiment of the present application have a simpler structure, a smoother adjustment process, no self-locking and jamming problems, low processing accuracy requirements, and a shorter basic length of the guide column and guide sleeve, which is more conducive to cost saving and arrangement in some locations with smaller installation space.
[0032] like Figure 4 and Figure 5 As shown, in one embodiment, the adjustment assembly 30 includes an adjustment unit 31 and a sliding portion 33. The two ends of the adjustment unit 31 are movably connected to the first support member 10 and the sliding portion 33 respectively. The sliding portion 33 is slidably arranged in the second support member 20. A reserved gap is provided between the outer surface of the sliding portion 33 and the inner surface of the second support member 20 along the transverse direction of the template 100 to allow the sliding portion 33 to swing laterally along the template relative to the second support member 20.
[0033] like Figure 4 and Figure 5 In one embodiment, the second support member 20 is a guide sleeve structure, and the sliding portion 33 is a guide post structure slidably disposed within the guide sleeve structure. In one embodiment, the guide sleeve structure and the guide post structure are secured to each other using a pin 40. Specifically, the adjustment assembly 30 of this structure is simple in structure, easily slides with the second support member 20, provides a stable and reliable adjustment process, is easy to manufacture, and is low in cost.
[0034] Specifically, if Figure 1 、 Figure 2 and Figure 7 As shown, in the existing adjustable support assembly, since its sliding position is set in the middle of the adjustable support assembly, the guide post 10a and the guide sleeve 10b are both connected to the bracket 200 through a hinge. The gap between the guide post 10a and the guide sleeve 10b will cause the two to be not on the same axis. When the angle is greater than a certain angle, the two are prone to self-locking. The guide post and guide sleeve matching structure with the same gap is reserved. The less the overlap, the greater the angle of free movement. Figure 4 、 Figure 5As shown, the adjustable support assembly provided by the embodiment of the present application has a second support member 20 with a guide sleeve structure at the lower end, which is fixed to the bracket 200. The sliding portion 33 is a guide post structure. The guide post structure and the guide sleeve structure only need to be connected by a pin shaft. Therefore, whether there is an angle between the two does not affect the working process of the adjustable support assembly. The guide post and the guide sleeve do not need to have a small clearance fit, nor do they need to overlap for a long length. Figure 8 As shown, the adjustable support assembly provided in the embodiment of the present application does not require precise matching between the guide sleeve and the guide column compared to the existing adjustable support assembly. A larger gap can be reserved to avoid self-locking, and there is no requirement for the overlap length. It only needs to be able to install the pin shaft normally.
[0035] In one embodiment, the adjustment unit 31 includes a screw 313, an adjustment member 315 mounted on the screw 313, and fixed nuts 317 mounted on both ends of the screw 313. The fixed nuts 317 securely connect the ends of the screw 313 to the first support member 10 and the sliding portion 33, respectively. The adjustment member 315 is used to rotate the screw 313 to adjust the overlap length between the screw 313 and the first support member 10 and the sliding portion 33, respectively. Specifically, the adjustment unit 31 only uses the screw 313 and the fixed nut 317 to cooperate with the first support member 10 and the sliding portion 33, respectively, to adjust the distance between the opposite ends of the first support member 10 and the second support member 20. This results in a simple and compact structure, easy installation and adjustment, and low cost.
[0036] In one embodiment, the first support member 10 is a columnar structure, one end of which is provided with a hinge plate 103 for hinged connection to the template 100. In one embodiment, one side of the second support member 20 is provided with a reinforcement plate structure 201 for connecting to the bracket 200. Specifically, by adding the hinge plate 103 and the reinforcement plate structure 201, the overall structural strength, stability and reliability of the adjustable support assembly can be greatly improved.
[0037] Based on the same concept as the aforementioned utility model, an embodiment of the present application also provides a template system, which includes a template 100 and a bracket 200. The template system is provided with an adjustable support assembly as in the aforementioned embodiment, wherein one end of the first support member 10 is rotatably connected to the template 100, and one end of the second support member 20 is fixedly connected to the bracket 200.
[0038] According to the above embodiments, it can be seen that the adjustable support assembly and template system involved in the present application have a simpler structure than the existing technology, a smoother adjustment process, no self-locking and jamming problems, low processing precision requirements, and a shorter basic length of the guide column and guide sleeve, which is more conducive to cost saving and arrangement in some locations with smaller installation space.
[0039] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited to this description. Any changes or substitutions that can be easily made by a person skilled in the art within the technical scope disclosed in the present invention should be included in the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the appended claims.
