Description
Technical Field
[0001] The utility model relates to the technical field of plain concrete, in particular to an adjustable anti-convex pad device applied to a plain concrete plug. Background Art
[0002] Fair-faced concrete is also called decorative concrete, which means that the natural surface of the cast concrete is used as the decorative surface without adding other external decorations. Unlike ordinary concrete, the fair-faced surface is provided with uniform cicada seams and bolt holes.
[0003] In the formwork construction of structural engineering, there are many styles of tension screws in the formwork reinforcement system, including traditional straight-through screws, multi-stage screws, etc., which mainly play a role in tightening the formwork by applying tension to ensure the stability of poured concrete. Since the formwork is made of wood and has a certain toughness, the tension screws are prone to slight deformation when they pass through the formwork during reinforcement, resulting in regular slight bulges on the structural wall. In general structural engineering, such deviations are within a reasonable range, and there are other decorative and renovation methods on the wall, which have no effect on the safety and appearance of the building. The plain concrete project is a construction method that is completed in one pouring without any decoration. Such uneven bulges greatly affect the appearance of the building, especially in the state of sunlight and light projection. To avoid this problem, wooden strips are added between the formwork and the main keel during construction, but this operation is too cumbersome and increases the cost at the same time. Therefore, it is necessary to provide an anti-bulge device that can reduce the impact of molding. Utility Model Content
[0004] The utility model aims to provide an adjustable anti-convex pad device for use in a clear water concrete plug, so as to achieve the situation in which, during the formwork reinforcement construction process, when the screw is being reinforced, the screw passes through the formwork without slight convexity, so that the clear water concrete after forming does not have slight convexity, thereby achieving the technical effect of reducing the influence of forming.
[0005] The utility model is realized by the following technical scheme: comprising a threaded screw and a plug sleeved on the end of the threaded screw, wherein the end of the plug is further provided with an external threaded rod;
[0006] It also includes an anti-convex component, which includes a connecting cap. The connecting cap is sleeved on the outer screw rod, and the end of the connecting cap is also connected to a terminal adjustment rod.
[0007] In order to better implement the present invention, further, the connecting cap is provided with an internal threaded hole toward the plug end, so that the external screw rod can cooperate with the connecting cap thread.
[0008] In order to better realize the utility model, further, a threaded column is provided at the end of the connecting cap facing the end adjusting rod, and a threaded hole is opened in the end adjusting rod so that the connecting cap and the end adjusting rod can be threadedly matched.
[0009] In order to better implement the utility model, further, the cross section of the end adjustment rod is in a convex shape.
[0010] In order to better realize the utility model, further, it also includes two templates, both of which have secondary keels installed on the outer sides of the two templates, and the main keel is installed on the outer side of the secondary keel;
[0011] The threaded screw is placed between the two templates, the anti-convex components are arranged between the template and the main keel, and the width of the anti-convex components is consistent with the width of the secondary keel.
[0012] The beneficial effects of the utility model are:
[0013] The utility model provides an adjustable anti-convex pad device for clear water concrete plugging, in which a connecting cap and an end adjusting rod are sleeved on the plugging, so that during the operation of the template reinforcement system, the template and the main keel are no longer subject to the fixed force of the screw, which causes the template to bulge outward, thereby avoiding the occurrence of uneven clear water concrete after molding and improving the effect of the clear water concrete after molding. The device has a simple structure and is simpler to operate than the prior art using wooden pads, and it saves more construction costs and material costs, thereby reflecting that the adjustable anti-convex pad device provided by the application has strong practicality.

[0023] The technical solution of the present invention will be described below in conjunction with the accompanying drawings of the present invention.
[0024] It should be noted that similar reference numerals and letters represent similar items in the following drawings, so once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings. At the same time, in the description of the present utility model, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.
[0025] The utility model provides an adjustable anti-convex pad device for use in plain concrete plugging. In the prior art, in the formwork reinforcement construction of structural engineering, the reinforcement system needs to use screws, and the formwork 5 is tightened by applying a pulling force. However, since the formwork 5 is made of wood and has a certain toughness, the screw is prone to slight deformation when passing through the formwork 5, resulting in a slight bulge on the structural wall. For plain concrete, the uneven bulge greatly affects the building molding effect. In order to solve the above technical problems, the utility model designs an anti-convex structure to reduce the force on the contact between the screw and the formwork 5 during the reinforcement process of the formwork 5, thereby solving the technical problem of slight bulge on the formwork 5, and further achieving the overall flatness and beauty of the wall after molding.
[0026] As shown in the figure, the anti-convex pad device is applied to the template 5, and a secondary keel 6 is arranged on the outer side of the template 5, and a main keel 7 is arranged on the outer side of the secondary keel 6. The template 5 is fixed by passing the screw through the template 5. The pair of screws mainly includes a threaded screw 1, and the end of the threaded screw 1 is sleeved with a plug 2, and the plug 2 is arranged on the inner side of the template 5. An external screw 3 is also arranged at the end of the plug 2. The external screw 3 passes through the template 5 together with the threaded screw 1. An anti-convex component 4 is also provided. The anti-convex component 4 mainly includes a connecting cap 41 and an end adjustment rod 42. One end of the connecting cap 41 is matched with the external screw 3, and the other end of the connecting cap 41 is connected with the end adjustment rod 42. In the matched connection, as shown in the figure, the anti-convexity component 4 is arranged between the formwork 5 and the main keel 7, that is, it is arranged at the position of the secondary keel 6, and the width of the anti-convexity component 4 is consistent with the width of the secondary keel 6. The advantage of such a setting is that the anti-convexity component 4 can effectively avoid the situation in which the screw passes through the formwork 5 during the reinforcement construction of the formwork system, and the formwork 5 bulges outward, so that the concrete after molding will not bulge outward, thereby achieving uniform flatness and aesthetic requirements. The screw given in this embodiment is a threaded screw. In addition, it can also be applied to other tensioning systems, such as three-stage and five-stage screws.
[0027] As shown in the figure, the connecting cap 41 is provided with an internal threaded hole 43 toward the end of the plug 2, and is connected to the external screw rod 3 through the internal threaded hole 43. In addition, the connecting cap 41 is also provided with a threaded column 44 at the end toward the end adjustment rod 42, and is connected to the end adjustment rod 42 through the threaded column 44.
[0028] In order to facilitate matching the widths of different secondary keels 6 , the width of the end adjustment rod 42 can have a variety of sizes, so as to meet the needs of matching different secondary keels 6 .
[0029] The workflow of this utility model is as follows:
[0030] The threaded screw 1 is installed and set according to the structural thickness, and the sleeve plugs 2 are installed at both ends of the threaded screw 1, through holes are opened on the two templates 5, so that the threaded screw 1 and the external screw 3 pass through the through holes, and several secondary keels 6 are installed at intervals on the outer surface of the template 5, and then the connecting cap 41 of the anti-convex component 4 is threadedly sleeved on the external screw 3, and then the end adjustment rod 42 is sleeved on the threaded column 44 of the connecting cap 41, and the end adjustment rod 42 is used to adjust the overall anti-convex component 4 to be flush with the secondary keel 6, and finally the main keel 7 is installed.
[0031] By setting an adjustable anti-convex pad device, a connecting cap 41 and an end adjusting rod 42 are sleeved on the plug 2, so that during the reinforcement construction of the template system, the template 5 and the main keel 7 are no longer subject to the fixed force of the threaded screw, which causes the template 5 to bulge outward, thereby avoiding the unevenness of the formed clear-water concrete and improving the effect of the formed clear-water concrete. The device has a simple structure and is simpler to operate than the prior art using wooden pads, and it saves more construction costs and material costs, thereby reflecting that the adjustable anti-convex pad device of the present application has strong practicality.
[0032] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
