Description
Technical Field
[0001] The utility model relates to the technical field of building construction tools, in particular to a template reinforcement device for expansion joint construction. Background Art
[0002] Building construction refers to production activities during the implementation phase of engineering construction. It is the construction process of various types of buildings. It can also be said to be the process of turning various lines on the design drawings into physical objects at designated locations. Building expansion joints refer to a structural joint set at an appropriate position along the construction joint direction of a building or structure to prevent cracks or damage to the structure due to changes in climate and temperature. The expansion joint allows the building or structure to expand and contract horizontally along its length and is one of the common structures in building construction.
[0003] The existing support device for expansion joint construction has the following disadvantages when in use: after the formwork on both sides of the existing expansion joint construction process is completed, the distance between the formworks needs to be supported and fixed before the end concrete is poured. The existing expansion joint formwork fixing device is not stable enough when in use, and the formwork is prone to deformation, dislocation and other problems during concrete pouring. For this reason, we propose a formwork reinforcement device for expansion joint construction. Utility Model Content
[0004] The main purpose of the utility model is to provide a formwork reinforcement device for expansion joint construction. Through the support mechanism installed between the formworks, the formwork can be supported and fixed quickly and stably. At the same time, the support spacing width is adjustable to meet different construction requirements, which can effectively solve the problems in the background technology.
[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:
[0006] A template reinforcement device for expansion joint construction includes steel bars, templates and support mechanisms, templates are provided at the ends of the steel bars and support mechanisms are installed between the templates, the support mechanism includes a screw, an upper threaded connector, a lower threaded connector, a support plate and a support rod, an upper threaded connector and a lower threaded connector are respectively installed at the upper and lower ends of the outer circumference of the screw, support rods are installed on the sides of the upper threaded connector and the lower threaded connector and are movably connected to the support plate through the support rods.
[0007] Furthermore, an adjusting knob is welded at the end of the screw rod for conveniently turning the screw rod; the screw rod can be conveniently turned by the adjusting knob located at the end of the screw rod.
[0008] Furthermore, steel pins are provided at the connection points at both ends of the support rod to facilitate the adjustment of the angle of the support rod; the steel pin structure is located at the connection points at both ends of the support rod, so that the angle of the support rod can be smoothly adjusted when the screw is turned, thereby driving the displacement of the support plate.
[0009] Furthermore, the support mechanism is inserted between the templates at intervals and the support plate surface away from the screw rod is in contact with the template surface; different numbers of support devices can be selected and used simultaneously according to different expansion joint lengths to ensure stable support for the template.
[0010] Compared with the prior art, the utility model has the following beneficial effects: the screw structure is a screw with screw grooves in opposite directions at the upper and lower ends, and the upper and lower ends of the screw are respectively connected to the support plate by an upper threaded connector, a lower threaded connector and a support rod. After the steel bars at the end of the expansion joint are tied and the formwork is installed in place, the support mechanism is inserted into the interior between the formworks while the support plate is facing the formwork. The screw is turned. Since the screw grooves at the upper and lower ends are in opposite directions, the upper threaded connector and the lower threaded connector can be driven to move in opposite directions synchronously when turned, thereby increasing the spacing between the upper threaded connector and the lower threaded connector, and then the support plates are stretched open by the support rod until the support plates touch the formwork surface, thereby achieving support and fixation of the formwork. After casting and finalizing, the support mechanism can be taken out by turning the screw in the opposite direction to reduce the spacing between the support plates. The overall structure of the device is compact and simple, easy to operate, and low in cost. It can be applied to the construction of expansion joints of different widths, has high universality, and can be recycled and reused, thereby reducing the cost of use.

[0017] Among them, an adjustment knob 302 is welded at the end of the screw rod 301 for conveniently turning the screw rod 301, and steel pins 307 are provided at the connection points at both ends of the support rod 306 for conveniently adjusting the angle of the support rod 306; the adjustment knob 302 located at the end of the screw rod 301 makes it convenient to turn the screw rod 301, and the steel pin 307 structure is located at the connection points at both ends of the support rod 306, so that when the screw rod 301 is turned, the angle of the support rod 306 can be smoothly adjusted, thereby driving the displacement of the support plate 305.
[0018] Among them, the support mechanism 3 is inserted between the templates 2 at intervals and the surface of the support plate 305 away from the screw 301 is in contact with the surface of the template 2; different numbers of support devices can be selected and used simultaneously according to different expansion joint lengths to ensure stable support for the template 2.
[0019] It should be noted that the utility model is a formwork reinforcement device for expansion joint construction.
