Abstract
Description
Technical Field
[0001] This application relates to the field of casting formwork technology, and in particular to a construction formwork for safety in construction engineering. Background Technology
[0002] In the field of building construction, concrete pouring formwork is the core equipment for forming concrete components. Its main function is to limit the pouring range and shape of concrete according to design requirements. After the concrete hardens, it is removed to obtain components with the preset structure. It is widely used in the construction process of concrete structures such as walls, columns, and beams.
[0003] Currently, most common concrete pouring formwork on the market consists of a single base plate and simple fixing clips. Multiple base plates are spliced and fixed together by the clips to form the pouring space. However, this type of traditional formwork has obvious defects in practical applications: the connection method of the fixing clips can only achieve preliminary positioning between the base plates, and cannot accurately adjust the spacing between the base plates to ensure the tightness of the splice. During the pouring process, concrete is prone to leaking out from the gaps between the base plates (i.e., grout leakage), which not only leads to the waste of concrete materials, but also causes quality problems such as honeycomb and pitting on the surface of the formed component, requiring additional repair treatment, increasing construction costs and time. Utility Model Content
[0004] The purpose of this application is to address the shortcomings of the prior art by proposing a construction template for safe construction engineering.
[0005] To achieve the above objectives, this application adopts the following technical solution: a construction formwork for safety in construction engineering, comprising two formworks with plate-like structures and a connection mechanism for connecting the two formworks. The connection mechanism includes a primary connection component and a secondary connection component. Two sliding rails are provided parallel to each other along the length of the formwork on the side away from the concrete pouring surface (i.e., the back side). The two sliding rails are symmetrically distributed on both sides of the back side of the formwork, and the grooves of the sliding rails face the direction away from the formwork.
[0006] Preferably, the secondary assembly includes a sliding rod, a sliding column, a sliding panel, and a limiting panel. The sliding rod is fixedly connected to the end face of one of the templates along the side length direction. The inner wall of the sliding column and the arc surface of the sliding rod are slidably connected along the axial direction of the sliding rod. The sliding panel is vertically fixed to the end of the sliding column opposite to the sliding rod. The limiting panel is vertically fixed to the end face of the sliding panel opposite to the template, and the inner wall of the limiting panel is through-hole along its thickness direction and is rotatably connected to the adjusting screw around its own axis.
[0007] Preferably, the primary mounting component includes a locking plate, a positioning seat plate, a sliding sleeve, a sliding column, and a baffle plate. The locking plate is fixedly connected to the end face of the other template along its side length, and the locking plate is correspondingly positioned to the top of the limiting panel. One end face of the positioning seat plate is fixedly connected to the locking plate, and the other end face is threadedly connected to the end of the adjusting screw away from the limiting panel along the axis of the adjusting screw. Rotating the adjusting screw can drive the positioning seat plate to move closer to or away from the limiting panel along the axial direction of the adjusting screw. A sliding sleeve is fixedly connected to one end of the sliding panel in a direction perpendicular to the locking plate. The inner wall of the sliding sleeve is slidably connected to the arc surface of the sliding column along the axial direction of the sliding sleeve. A baffle is fixedly fixed to one end of the sliding column. A primary elastic element is fixedly connected between the two baffles along the axial direction of the sliding column. Two locking slots are opened on the side end face of the sliding panel facing the sliding column along its own surface direction corresponding to the position of the sliding column. The inner wall of the locking slot is slidably connected to the arc surface of the sliding column along the groove depth direction.
[0008] Preferably, protective pads are fixedly attached to both of the two templates facing each other, covering the entire contour of the side surface. The thickness direction of the protective pads is perpendicular to the side surface of the templates. When the two templates are close to each other, the protective pads can achieve a seal between the two templates.
[0009] Preferably, one end of the template is provided with a cleaning mechanism for cleaning the pouring surface. The cleaning mechanism includes a fixed shaft, a fixed seat plate, a cleaning brush, and a handle. The two ends of the fixed shaft are respectively embedded in the two sliding rails, and the arc surface of the fixed shaft is slidably connected to the inner wall of the sliding rail along the length of the sliding rail. The fixed seat plate is sleeved on the arc surface of the fixed shaft along the axial direction and is slidably connected to the fixed shaft. The brush handle end of the cleaning brush is fixedly connected to the side of the fixed seat plate facing the pouring surface of the template, and the bristles of the cleaning brush can fit against the pouring surface of the template. The handle has a "U" shaped cross section, with its open end facing the fixed seat plate and fixedly connected to the end face of the fixed seat plate away from the cleaning brush. The handle can drive the fixed seat plate to move along the axial direction of the fixed shaft and the length of the sliding rail.
[0010] Preferably, a secondary elastic member is sleeved on the arc surface of the fixed shaft along its own axial direction, and an annular limiting platform is radially protruded on the outer peripheral wall of the fixed shaft. One end of the secondary elastic member is fixedly connected to the end face of the fixed seat plate facing the limiting platform, and the other end is fixedly connected to the end face of the limiting platform. The secondary elastic member can drive the fixed seat plate to press the cleaning brush body towards the direction of conforming to the casting surface through its own elasticity.
[0011] Preferably, the two ends of the fixed shaft away from the fixed seat plate are respectively integrally formed with limiting spheres. The diameter of the limiting spheres is larger than the width of the groove of the sliding track, and the arc surface of the limiting spheres slides and engages with the inner wall of the sliding track along the track length direction. The limiting spheres can prevent the fixed shaft from coming out of the groove of the sliding track.
[0012] In this application, the optimized design of the assembly mechanism effectively solves the problems of poor sealing and reliance on manual squeezing in traditional templates. The sliding column of the first-stage assembly and the snap-fit groove of the sliding panel can achieve rapid initial positioning of the two templates. The adjusting screw of the second-stage assembly and the threaded engagement of the positioning seat plate can precisely drive the substrate to move closer along the axial direction. With the protective pad on the splicing surface of the substrate, a tight sealing structure can be formed at the splicing point of the substrate, completely avoiding the phenomenon of concrete leakage during pouring. There is no need for continuous manual squeezing and supervision, which significantly reduces labor input, improves the efficiency of pouring operation, ensures the forming quality of concrete components, and reduces repair costs.
[0013] In this application, the cleaning mechanism solves the problems of low cleaning efficiency and easy damage to the substrate in traditional template cleaning. The fixed shaft can move smoothly along the sliding track on the back of the template. When the fixed seat plate drives the cleaning brush to move, the secondary elastic component can continuously provide pressure to the cleaning brush towards the pouring surface, ensuring that the steel wire bristles are closely attached to the substrate surface, efficiently removing residual concrete residue. There is no need for manual scraping with hard tools, which not only improves cleaning efficiency, but also avoids scratches and wear on the substrate surface, extends the service life of the template, and reduces equipment replacement costs.
[0014] In this application, the overall structural design takes into account both ease of assembly and practicality of turnover. The primary and secondary connectors of the assembly mechanism work together to enable rapid assembly and disassembly of the substrate. The cleaning mechanism can be used in tandem with the template without the need to carry additional special cleaning tools. The operation process is simple and easy to understand, and construction personnel can operate it proficiently after simple training, which further improves the smoothness of the construction process, reduces the overall construction cost, and is suitable for concrete pouring operations of different scales, and has broad practical value.

[0017] Reference Figures 1-4 As shown, this application provides a technical solution: a construction template for safety in construction engineering, including two templates 1 with plate-like structures and a connection mechanism 2 for connecting the two templates 1. The connection mechanism 2 includes a primary connection component 21 and a secondary connection component 22.
[0018] The secondary assembly 22 includes a sliding rod 221, a sliding column 202, a sliding panel 222, and a limiting panel 224. The sliding rod 221 is fixedly connected to the end face of one of the templates 1 by welding along the side length of the template 1. The sliding column 202 is a hollow column structure and its inner wall is tightly fitted with the arc surface of the sliding rod 221. The two can slide smoothly along the axial direction of the sliding rod 221. The sliding panel 222 is made of metal and is vertically welded to the end of the sliding column 202 away from the sliding rod 221. The limiting panel 224 is also made of metal and is vertically fixed to the end face of the sliding panel 222 away from the template 1. The inner wall of the limiting panel 224 forms a mounting hole along its thickness direction. A bearing can be installed in the mounting hole. The adjusting screw 225 passes through the inner ring of the bearing and forms a rotational connection with the limiting panel 224 around its own axis.
[0019] The primary mounting component 21 includes a locking plate 211, a positioning seat plate 212, a sliding sleeve 213, a sliding column 215, and a baffle plate 214. The locking plate 211 is welded to the end face of the template 1 along the side length direction of the other template 1, corresponding to the position of the sliding rod 221. The top of the locking plate 211 is at the same height as the top of the limiting panel 224 and is correspondingly set. The positioning seat plate 212 is a rectangular metal plate, one end face of which is fixedly connected to the locking plate 211 by bolts, and the other end face is provided with an adjusting screw. The adjusting screw 225 has a matching internal threaded hole. The end of the adjusting screw 225 away from the limiting panel 224 is screwed into the internal threaded hole, and the two form a threaded fit along the axis of the adjusting screw 225. When the adjusting screw 225 is rotated, it can drive the positioning seat plate 212 to move closer to or away from the limiting panel 224 along the axis of the adjusting screw 225. The end of the engaging plate 211 near the sliding panel 222 is welded with a sliding sleeve 213 in a direction perpendicular to the surface of the engaging plate 211. The sliding sleeve 213 is a hollow tubular structure and its inner wall is connected to the sliding column 21. The arc surface of the sliding column 215 fits together with the sliding sleeve 213, allowing the sliding column 215 to slide along the axial direction of the sliding sleeve 213. A circular baffle 214 is vertically welded to one end of the sliding column 215. A primary elastic element 216 is sleeved between the two baffles 214 along the axial direction of the sliding column 215. The primary elastic element 216 is a compression spring and, in its natural state, can push the two baffles 214 away from each other, thereby causing the sliding column 215 to extend out of the sliding sleeve 213. The sliding panel 222 faces one end face of the sliding column 215 along its own surface direction. Two arc-shaped snap-fit slots 223 are provided at the position of the sliding column 215. The inner wall of the snap-fit slot 223 is adapted to the arc surface of the sliding column 215. The sliding column 215 can slide into the snap-fit slot 223 along the groove depth direction to achieve initial positioning. Protective pads are fully covered and bonded along the contour of the side of each of the two templates 1 facing each other. The protective pads are made of elastic rubber and their thickness direction is perpendicular to the side of the template 1. When the two templates 1 are close to each other, the protective pads can be squeezed and deformed to fill the gap between the two substrates.
[0020] Two sliding tracks 3 are parallel to the length of the template 1 on the side away from the concrete pouring surface (i.e., the back side). The sliding tracks 3 are rectangular groove structures, and the two sliding tracks 3 are symmetrically distributed on both sides of the back side of the template 1. The groove openings of the sliding tracks 3 face away from the template 1, and the inner walls of the tracks are smoothed. One end of the template 1 is provided with a cleaning mechanism 4 for cleaning the pouring surface. The cleaning mechanism 4 includes a fixed shaft 44, a fixed seat plate 41, a cleaning brush 43, and a handle 42. The fixed shaft 44 is a metal round rod, and its two ends are respectively embedded in the two sliding tracks 3. The arc surface of the fixed shaft 44 fits against the inner wall of the sliding track 3 and can slide along the length of the sliding track 3. The fixed seat plate 41 is a rectangular plate with a circular through hole in its center. The fixed seat plate 41 is sleeved on the arc surface of the fixed shaft 44 along the axial direction of the fixed shaft 44 through the through hole and can slide along the shaft. The brush handle end of the cleaning brush 43 is bolted to the fixed seat plate 41 facing away from the template 1. The cleaning brush body 43 is fixedly connected to one end face of the pouring surface of the template 1. The steel wire bristles of the cleaning brush body 43 are made of wear-resistant steel wire and can naturally fit against the pouring surface of the template 1. The handle 42 is made of metal and has a "U" shaped cross-section. Its open end faces the fixed base plate 41 and is welded and fixed to the end face of the fixed base plate 41 away from the cleaning brush body 43. The arc surface of the fixed shaft 44 is fitted with a secondary elastic element 45 along its own axis. The secondary elastic element 45 is a compression spring. The outer surface of the fixed shaft 44... An annular limiting platform is integrally formed radially on the peripheral wall. One end of the secondary elastic component 45 is welded to the end face of the fixed base plate 41 facing the limiting platform, and the other end is welded to the end face of the limiting platform. The two ends of the fixed shaft rod 44 away from the fixed base plate 41 are integrally formed with limiting spheres 46. The limiting spheres 46 are metal spheres and their diameter is larger than the groove width of the sliding track 3. The arc surface of the limiting spheres 46 is polished and fits against the inner wall of the sliding track 3, allowing it to slide along the length of the track.
[0021] Working principle Before pouring concrete, the two templates 1 are assembled. The sliding column 202 is pushed to move axially along the sliding rod 221. The position of the sliding panel 222 is adjusted so that the sliding column 215 is aligned with the snap-fit groove 223 on the sliding panel 222. Under the elastic thrust of the first-level elastic member 216, the sliding column 215 extends axially along the sliding sleeve 213 and slides into the snap-fit groove 223, achieving the initial positioning of the two templates 1. Then, the adjusting screw 225 is rotated. Since the adjusting screw 225 is rotatably connected to the limiting panel 224 and threadedly engaged with the positioning seat plate 212, the positioning seat plate 212 will move closer to the limiting panel 224 along the axial direction of the adjusting screw 225 during rotation, thereby driving the two templates 1 to move closer to each other until the protective pad 212 is squeezed and deformed, completely filling the gap between the two base plates, ensuring that the concrete will not flow out during pouring.
[0022] After the concrete is poured and hardened, when it is necessary to clean the pouring surface of the formwork 1, the operator holds the handle 42 and pushes the fixed seat plate 41 to move axially along the fixed shaft 44. At the same time, the fixed shaft 44 can be driven to slide along the length of the sliding track 3. Under the elastic action of the secondary elastic member 45, the fixed seat plate 41 will be pushed towards the pouring surface, so that the steel wire bristles of the cleaning brush 43 are always closely attached to the pouring surface, thereby efficiently removing the residual concrete on the pouring surface. During this process, the limiting ball 46, because its diameter is larger than the width of the groove of the sliding track 3, can prevent the fixed shaft 44 from coming out of the groove of the sliding track 3, ensuring that the cleaning operation is stable. After cleaning, the adjusting screw 225 is rotated in the opposite direction to move the positioning seat plate 212 away from the limiting panel 224, and the sliding column 215 is pulled away from the snap-fit groove 223, so that the two formwork 1s can be separated for subsequent reuse.
[0023] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
