Description

Technical Field

[0001] This utility model relates to the field of external vibration device technology, and in particular to an external vibration device for reinforcing reinforced concrete surface layers. Background Technology

[0002] Reinforced concrete surface layer reinforcement is a method used to strengthen masonry structures. A certain thickness of concrete is poured onto the side of the masonry wall to enhance the load-bearing capacity of the original masonry structure. This method is widely used in the reinforcement of existing buildings.

[0003] A search revealed an external vibratory compaction device for reinforcing reinforced concrete surfaces, published under publication number CN215291619U. This device includes a reinforced brick wall with reinforced concrete surfaces on both sides. An inner template is installed on the outer side of each reinforced concrete surface. Two rows of through holes are drilled through the inner template, the reinforced concrete surfaces, and the upper and lower sides of the reinforced brick wall, respectively. Plastic sleeves are installed within these through holes. A sealing steel plate is tightly fitted to the inner template via rubber pads. A round steel bar passes through the sealing steel plate and rubber pads into the plastic sleeves. Both ends of the round steel bar are threaded, and nuts are tightened to secure the sealing steel plate. Vibrator connecting studs are welded to the surface of the sealing steel plate, and the vibrator is fixed to the sealing steel plate via these studs. This invention can be pre-fabricated and installed on-site. After installation, the device can be adjusted according to the height of the reinforced wall, the thickness of the concrete surface, and the vibration spacing, making it suitable for reinforcing masonry structures of different sizes.

[0004] In the device disclosed in this patent, a connecting round steel is inserted into a plastic sleeve that penetrates the reinforced wall. The connecting round steel can move in the thickness direction of the reinforced wall. When pouring the reinforced concrete surface layer, if the formwork on both sides is subjected to uneven force when the reinforced concrete surface layer is poured, it is easy to cause the connecting round steel and the two formwork to move in the same direction along the reinforced wall, resulting in a large deviation in the thickness of the reinforced concrete surface layer, which affects the reinforcement effect of the reinforced wall. In addition, the device is fixed to the edge sealing steel plate by multiple sets of tamping device connecting studs, which not only limits the vibration position of the tamping device and affects the uniformity of vibration, but also requires frequent installation and disassembly of the tamping device, which affects the vibration efficiency of the reinforced concrete surface layer. Utility Model Content

[0005] In response to existing patents, to address the technical problems of the connecting round steel inserted into the plastic sleeve penetrating the reinforced wall during use, allowing the connecting round steel to move along the thickness of the reinforced wall, uneven stress on the formwork on both sides during the pouring of the reinforced concrete surface layer can easily lead to displacement of the connecting round steel and the two formwork along the reinforced wall, resulting in a large deviation in the thickness of the reinforced concrete surface layer and affecting the reinforcement effect. Furthermore, the use of multiple sets of tamping devices connected to the edge sealing steel plate with connecting studs not only limits the vibration position of the tamping devices and affects the uniformity of vibration, but also requires frequent installation and disassembly of the tamping devices, affecting the vibration efficiency of the reinforced concrete surface layer. This utility model provides an external vibrating device for reinforcing reinforced concrete surface layers.

[0006] The technical solution adopted by this utility model is: an external vibrating device for reinforcing reinforced concrete surface layer, comprising: a reinforcing wall and a vibrating device installation mechanism, wherein the reinforcing wall is provided with a concrete reinforcing surface layer on both sides, and a template is provided on the outside of the concrete reinforcing surface layer. The tamping device installation mechanism includes two tamping device installation components fixed on opposite sides of the template, multiple connecting round steel bars penetrating the reinforced wall, and two limiting nuts threaded into the connecting round steel bars penetrating the reinforced wall. The tamping device installation components include one or more T-shaped protrusions vertically arrayed on the outside of the template, a T-shaped guide bar horizontally slidably fitted on the side of the template, and a tamping device mounting seat vertically slidably fitted on the T-shaped guide bar. The T-shaped guide bar slidably fits on the T-shaped protrusions.

[0007] Furthermore, the tamping device installation assembly also includes a rubber layer fixed to the side of the template and an edge sealing steel plate fixed to one side of the rubber layer. The end of the connecting round steel penetrates the concrete reinforcement surface layer, the rubber layer, and the edge sealing steel plate and is threaded with a fixing nut. The T-shaped protrusion is provided on the side of the T-shaped protrusion.

[0008] Furthermore, the T-shaped guide strip has a first T-shaped opening groove on its side corresponding to the T-shaped protrusion. The T-shaped guide strip slides on the T-shaped protrusion through the first T-shaped opening groove. Both ends of the T-shaped protrusion are provided with a first limiting plate corresponding to the T-shaped guide strip.

[0009] Furthermore, a second T-shaped opening groove is provided on one side of the tamping device mounting base, and the tamping device mounting base slides on the T-shaped guide strip through the second T-shaped opening groove. The upper and lower ends of the T-shaped guide strip are provided with second limiting plates corresponding to the tamping device mounting base.

[0010] Furthermore, the T-shaped guide strip has a clearance notch on its side corresponding to the connecting round steel and the fixing nut, and the tamping device mounting base has multiple tamping device connecting studs on one side.

[0011] Furthermore, the tamping device mounting base has threaded screws on both sides, and the T-shaped guide strip has multiple positioning grooves on its side along the height direction that correspond to the screws.

[0012] The beneficial effects of this utility model are: By setting limit nuts, the probability of slippage of the connecting round steel is reduced, and the displacement of the connecting round steel and the formwork on both sides along the thickness direction of the reinforced wall is avoided during the pouring of the reinforced concrete surface layer. This would result in a large error in the thickness of the reinforced concrete surface layer on both sides of the reinforced wall, which would affect the reinforcement effect of the reinforced wall. By setting up T-shaped protrusions, T-shaped guide strips, and tamping device mounting bases, it is easy to guide the T-shaped guide strips, tamping device mounting bases, and tamping devices to slide horizontally. This facilitates the tamping device to vibrate the concrete reinforcement layer at different positions along the horizontal length of the template, avoiding frequent disassembly and reassembly of the tamping device and improving the efficiency of vibrating the concrete reinforcement layer. The T-shaped guide strips guide the tamping device mounting base and tamping device to slide vertically, facilitating the tamping device to vibrate the concrete reinforcement layer at different heights of the template. This allows the tamping device to work continuously in both the horizontal and vertical directions, improving the uniformity of the vibrated concrete reinforcement layer. By setting a Phillips head handle screw, when long-term vibration is required at any height of the template, the Phillips head handle screw is screwed into the positioning groove to facilitate the limiting of the tamping device, avoiding long-term manual limiting of the tamping device by workers and reducing the workload of workers.

[0017] The following is in conjunction with the appendix Figure 1-4 The present invention will be further described below.

[0018] To address the problems existing in the background art, this application proposes the following technical solution: An external vibrating device for reinforcing reinforced concrete surface layer includes: a reinforced wall 1 and a vibrator installation mechanism 2. The reinforced wall 1 is provided with a concrete reinforced surface layer 101 on both sides, and a template 102 is provided on the outside of the concrete reinforced surface layer 101. The tamping device installation mechanism 2 includes two tamping device installation components fixed on opposite sides of the template 102, multiple connecting round steel bars 200 penetrating the reinforced wall 1, and two limiting nuts 201 threadedly engaged with the connecting round steel bars 200 penetrating both ends of the reinforced wall 1. The tamping device installation components include one or more T-shaped protrusions 205 arranged vertically on the outside of the template 102, T-shaped guide bars 206 slidably engaged on the side of the template 102, and tamping device mounting bases 207 slidably engaged on the T-shaped guide bars 206. The T-shaped guide bars 206 slidably engage on the T-shaped protrusions 205.

[0019] Furthermore, the tamping device installation assembly also includes a rubber layer 203 fixed to the side of the template 102, an edge sealing steel plate 204 fixed to one side of the rubber layer 203, a connecting round steel 200 end penetrating the concrete reinforcement surface layer 101, the rubber layer 203, and the edge sealing steel plate 204 with a threaded fixing nut 202, and a T-shaped protrusion 205 is provided on the side of the T-shaped protrusion 205.

[0020] Furthermore, the T-shaped guide strip 206 has a first T-shaped opening groove 208 on its side corresponding to the T-shaped protrusion 205. The T-shaped guide strip 206 slides on the T-shaped protrusion 205 through the first T-shaped opening groove 208. Both ends of the T-shaped protrusion 205 are provided with a first limiting plate 209 corresponding to the T-shaped guide strip 206.

[0021] Furthermore, a second T-shaped opening groove 210 is provided on one side of the tamping device mounting base 207. The tamping device mounting base 207 slides on the T-shaped guide strip 206 through the second T-shaped opening groove 210. Both the upper and lower ends of the T-shaped guide strip 206 are provided with second limiting plates 211 corresponding to the tamping device mounting base 207.

[0022] Furthermore, the T-shaped guide bar 206 has a clearance notch 212 on its side corresponding to the connecting round steel 200 and the fixing nut 202, and the tamping device mounting base 207 has multiple tamping device connecting studs 213 on one side. By setting the clearance notch 212, it is easy to avoid the connecting round steel 200 and the fixing nut 202 from affecting the sliding of the T-shaped guide bar 206.

[0023] Furthermore, the tamping device mounting base 207 has threaded engagement of Torx handle screws 214 on both sides, and the T-shaped guide strip 206 has multiple positioning grooves 215 on its side along the height direction corresponding to the Torx handle screws 214.

[0024] Working principle: By setting the limit nut 201, the probability of slippage of the connecting round steel 200 is reduced, avoiding the displacement of the connecting round steel 200 and the two side formworks 102 in the same direction along the thickness direction of the reinforced wall 1 during the pouring of the reinforced concrete surface layer 101. This would cause a large error in the pouring thickness of the reinforced concrete surface layer 101 on both sides of the reinforced wall 1, affecting the reinforcement effect of the reinforced wall 1. The tamping device is installed on the tamping device mounting base 207 through the tamping device connecting stud 213. Then, the T-shaped guide strip 205 guides the T-shaped guide strip 206, the tamping device mounting base 207, and the tamping device to slide horizontally, facilitating the tamping device to vibrate the concrete at different positions along the horizontal length direction of the formwork 102. The solid surface layer 101 facilitates the efficient vibration of the concrete reinforcement surface layer 101 by avoiding frequent disassembly and installation of the tamping device. The T-shaped guide strip 206 guides the tamping device mounting base 207 and the tamping device to slide vertically, which facilitates the tamping device to vibrate the concrete reinforcement surface layer 101 at different heights of the template 102. It also facilitates continuous operation of the tamping device in both horizontal and vertical directions, improving the uniformity of the vibration of the concrete reinforcement surface layer 101. By setting the Phillips head handle screw 214, when long-term vibration is required at any height of the template 102, the Phillips head handle screw 214 is screwed into the positioning groove 215 to limit the tamping device, avoiding long-term manual limiting of the tamping device by workers and reducing the labor intensity of workers.
