Description

Technical Field

[0001] This utility model relates to the field of beam-column joint formwork reinforcement, specifically a splicing type reinforcement device for complex beam-column joint formwork. Background Technology

[0002] When constructing a building, it is necessary to erect vertical columns and horizontal beams in the foundation to support the floor slabs, and pour concrete between the beams and columns to prevent the beams and columns from being exposed to the outside air for a long time, which would reduce their rigidity. In order to better fix the beams and columns, it is usually necessary to add formwork between the beams and columns and pour concrete for shaping. After shaping, the formwork can be removed for future use.

[0003] Existing splicing reinforcement formwork typically involves directly covering the outside of beams and columns with wooden boards and securing them with bolts. After concrete is injected, the formwork is squeezed outwards by the injection chamber, causing it to tilt outwards. During the grouting process, concrete is easily missed, resulting in low overall structural rigidity. Utility Model Content

[0004] To overcome the shortcomings of existing technologies, after concrete is injected, the formwork in the injection chamber is squeezed outward and protrudes outward, causing the formwork to tilt outward. During the grouting process, concrete is easily missed, resulting in low overall structural rigidity. This utility model proposes a splicing type reinforcement device for complex beam-column joint formwork.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a splicing type reinforcement device for complex beam-column joint template, including a vertical column and a horizontal beam. Two sets of T-shaped reinforcing ribs are fixedly connected to the surface of the vertical column, and the outer side of the T-shaped reinforcing ribs is fixedly connected to the horizontal beam. Fastening bolts are threadedly connected at the overlapping part of the vertical column and the horizontal beam. A wooden template body is sleeved on the outer side of the vertical column and the horizontal beam, and a reinforcement component is provided on the outer side of the wooden template body.

[0006] The reinforcement component includes a pressing base, one side of which is attached to the surface of the wooden template body. A pressing plate is rotatably connected to the surface of the pressing base. An extension frame is fixedly connected to the surface of the pressing plate. A fixing plate is fixedly connected inside the extension frame. A first vertical sliding groove is formed on the surface of the fixing plate. An operating plate is fixedly connected to the surface of the extension frame. A second vertical sliding groove is formed on the surface and both sides of the operating plate. Limiting blocks are fixedly connected at equal intervals on both sides of the second vertical sliding groove on the surface of the operating plate. A sliding plate slides inside the second vertical sliding groove on both sides of the operating plate. The surface of the sliding plate abuts against the outside of the limiting block. A handle is fixedly connected inside the sliding plate. The handle passes through the second vertical sliding groove on the surface of the operating plate and the first vertical sliding groove on the surface of the fixing plate, respectively. A blocking block is fixedly connected to one end of the handle. A spring is sleeved on the outside of the blocking block. The starting and ending ends of the spring are respectively located between the blocking block and the fixing plate.

[0007] Preferably, a limiting sleeve is fixedly connected above the bearing surface of the pressing base. The surface of the limiting sleeve is provided with an arc-shaped groove. An elastic support strip is fixedly connected inside the limiting sleeve. The other end of the elastic support strip is fixedly connected to the side of the sliding plate. The center position of the sliding plate slides in the square groove inside the operating plate. The two sides of the sliding plate slide in the second vertical sliding grooves on both sides of the operating plate.

[0008] Preferably, the surfaces of the pressing plate and the pressing base are respectively attached to the outside of the wooden template body, and the wooden template body, the vertical columns and the horizontal beams are all sprayed with a release agent.

[0009] Preferably, the bottom end of the wooden template body is provided with a stabilizing component, which includes a square tube. The bottom end of the square tube is fixedly connected to a clamping leg. A sliding sleeve is provided on the side away from the square tube, and a pull rod is sleeved on the outside of the sliding sleeve. Limiting grooves are provided on the surfaces of the square tube, the sliding sleeve, and the pull rod. A special-shaped pin slides up and down inside the limiting groove at the overlap of the square tube, the sliding sleeve, and the pull rod.

[0010] Preferably, the top of the irregularly shaped pin is made of a wear-resistant rubber material, and the surface of the irregularly shaped pin is configured to be wider at the top and narrower at the bottom.

[0011] Preferably, the sliding sleeve and the pull rod are respectively disposed on the outer side of the wooden template body, and the sliding sleeve slides back and forth on the surface of the pull rod.

[0012] Preferably, the inner cavity of the wooden template body and the surfaces of the vertical columns and horizontal beams are provided with grouting chambers, and the horizontal beams are provided with an I-beam shape.

[0013] The advantages of this utility model are:

[0014] This invention adds a wooden formwork body at the overlap of the vertical column and horizontal beam. The grouting chamber between the wooden formwork body and the vertical column and horizontal beam can be used for concrete injection. Reinforcing components are added at the corners of the vertical column and horizontal beam to hold the wooden formwork body in place when it tilts due to the expansion of the concrete. The angle between the pressure plate and the wooden formwork body is adjusted by pulling a sliding plate to overcome the resistance of the spring, thus securing the wooden formwork body. A stabilizing component is added to the bottom of the wooden formwork body, which moves towards the surface of the wooden formwork body through clamping legs and sliding sleeves to clamp the wooden formwork body and prevent it from falling off. The square tube and pull rod are designed to be adjustable to accommodate different models of wooden formwork bodies. After the concrete dries and detaches the wooden formwork body from the surface of the vertical column and horizontal beam, the wooden formwork body can still be used. This solves the problem that ordinary reinforcement devices cannot prevent the concrete from spreading after the wooden formwork body tilts, thus making it impossible to secure the vertical column and horizontal beam.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0024] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0025] This application discloses a splicing type reinforcement device for formwork of complex beam-column joints. (Refer to...) Figure 1 and Figure 6 A splicing type reinforcement device for complex beam-column joint formwork includes a vertical column 1 and a horizontal beam 2. Two sets of T-shaped reinforcing ribs 11 are fixedly connected to the surface of the vertical column 1. The outer side of the T-shaped reinforcing ribs 11 is fixedly connected to the horizontal beam 2. Fastening bolts 21 are threadedly connected at the overlapping part of the vertical column 1 and the horizontal beam 2. A wooden formwork body 3 is sleeved on the outer side of the vertical column 1 and the horizontal beam 2. A reinforcement component 4 is provided on the outer side of the wooden formwork body 3.

[0026] The reinforcing component 4 includes a pressing base 414, one side of which is attached to the surface of the wooden template body 3. A pressing plate 413 is rotatably connected to the surface of the pressing base 414. The pressing plate 413 and the pressing base 414 are used to press the wooden template body 3 together. An extension frame 41 is fixedly connected to the surface of the pressing plate 413. A fixing plate 42 is fixedly connected inside the extension frame 41. A first vertical sliding groove 43 is provided on the surface of the fixing plate 42. An operating plate 46 is fixedly connected to the surface of the extension frame 41. A second vertical sliding groove 48 is provided on the surface and both sides of the operating plate 46. Limiting blocks 47 are fixedly connected at equal intervals on both sides of the second vertical sliding groove 48 on the surface of the operating plate 46. 7 is used to block the sliding plate 49 and prevent the pressing plate 413 from shifting to the position of the pressing base 414. The sliding plate 49 slides inside the second vertical sliding groove 48 on both sides of the operating plate 46. The surface of the sliding plate 49 is pressed against the outside of the limiting block 47. The inside of the sliding plate 49 is fixedly connected to the handle 410. The handle 410 passes through the second vertical sliding groove 48 on the surface of the operating plate 46 and the first vertical sliding groove 43 on the surface of the fixing plate 42. One end of the handle 410 is fixedly connected to the blocking block 44. The outside of the blocking block 44 is fitted with a spring 45. The beginning and end of the spring 45 are respectively set between the blocking block 44 and the fixing plate 42. The pressing plate 413 is used to provide compression deformation space for the spring 45.

[0027] Reference Figure 3 and Figure 4 A limiting sleeve 411 is fixedly connected above the bearing surface of the pressing base 414. An arc-shaped groove is opened on the surface of the limiting sleeve 411. An elastic support strip 412 is fixedly connected inside the limiting sleeve 411. When the pressing plate 413 and the pressing base 414 are not needed for support, the elastic support strip 412 can be removed from the limiting sleeve 411 by moving the elastic support strip 412, so that the pressing plate 413 and the pressing base 414 can be folded. Before this, the sliding plate 49 needs to be moved to the highest position of the second vertical sliding groove 48 on both sides of the operating plate 46.

[0028] Reference Figure 2 and Figure 3 The surfaces of the pressing plate 413 and the pressing base 414 are respectively attached to the outside of the wooden formwork body 3. The wooden formwork body 3, the vertical column 1 and the horizontal beam 2 are all sprayed with release agent. After the concrete is injected, the wooden formwork body 3 sprayed with release agent is easy to remove from the concrete surface. The disassembled wooden formwork body 3 can be recycled.

[0029] Reference Figure 1 and Figure 5The bottom of the wooden template body 3 is provided with a stabilizing component 5, which includes a square tube 51. The bottom of the square tube 51 is integrally formed with a clamping leg 53. On the side away from the square tube 51, there is an internally slidably connected pull rod 56. The outer side of the pull rod 56 is fitted with a sliding sleeve 52. The position of the sliding sleeve 52 on the pull rod 56 can be adjusted according to the on-site usage. Limiting grooves 55 are opened on the surface of the square tube 51, the sliding sleeve 52 and the pull rod 56. A special-shaped pin 54 slides up and down inside the limiting groove 55 at the overlap of the square tube 51, the sliding sleeve 52 and the pull rod 56.

[0030] Reference Figure 1 and Figure 5 The top of the irregularly shaped pin 54 is made of wear-resistant rubber material to reduce vibration during the hammering process. The surface of the irregularly shaped pin 54 is wider at the top and narrower at the bottom. As the irregularly shaped pin 54 slides towards the limiting groove 55 in the overlapping area of ​​the sliding sleeve 52 and the pull rod 56, it slides towards the limiting groove 55 in the surface of the sliding sleeve 52 after being subjected to external force. At the same time, the sliding sleeve 52 is squeezed by the irregularly shaped pin 54 and moves towards the clamping leg 53. During the grouting process of the wooden template body 3, it can be used to support the squeezed wooden template body 3 and prevent tilting and movement.

[0031] Reference Figure 1 and Figure 5 The clamping legs 53 and the pull rod 56 at the bottom of the square tube 51 are respectively set on the outside of the wooden template body 3. They are used to hold the wooden template body 3 covering the outside of the vertical column 1 tightly, so as to prevent the wooden template body 3 from falling off the outside of the vertical column 1 under the action of gravity during the grouting process. The sliding sleeve 52 slides back and forth on the surface of the pull rod 56. The adjustable design makes it convenient to clamp different models of wooden template bodies 3.

[0032] Reference Figure 3 and Figure 4 The inner cavity of the wooden formwork body 3 and the surfaces of the vertical column 1 and the horizontal beam 2 are provided with grouting chambers, which facilitates the flow of concrete from the grouting chambers to the areas that need to be reinforced. The horizontal beam 2 is made of I-beam steel, and the web area of ​​the horizontal beam 2 is connected to the T-shaped reinforcing bar 11 by fastening bolts 21. This hinged joint does not restrict the rotation of the horizontal beam 2, and the pressure on the horizontal beam 2 will not be transmitted to the vertical column 1. This assembly method increases the overall rigidity.

[0033] Working principle: First, the vertical column 1 is fixed perpendicularly to the foundation. Then, the T-shaped reinforcing ribs 11 welded and fixed to the surface of the horizontal beam 2 and the vertical column 1 are aligned to form a vertical angle between the vertical column 1 and the horizontal beam 2. After measuring with a laser level, the vertical angle between the two sets is maintained. Then, the fastening bolts 21 are screwed into the horizontal beam 2, the T-shaped reinforcing ribs 11, and the vertical column 1 respectively to fix the vertical column 1 and the horizontal beam 2. Next, the wooden template body 3 is covered on the outside of the vertical column 1 and the horizontal beam 2. The pressing plate 413 and the pressing base 414 are placed on the surface of the wooden template body 3 in the angle area between the vertical column 1 and the horizontal beam 2. Another set of pressing plates 413 and pressing bases 414 are placed in a symmetrical area in the horizontal direction. Screws are added to the surface of the wooden template body 3 to tighten the pressing plates 413 and the pressing bases 414. After completing this work, the vertical column 1 is then... The wooden template body 3 covering the outside of column 1 is tightened. First, the pull rod 56 is slid out from the outlet of the square tube 51. According to the width of the wooden template body 3, the position of the sliding sleeve 52 is adjusted to be the same as the surface size of the wooden template body 3. The clamping leg 53 welded and fixed to the surface of the square tube 51 is tightened from one side of the wooden template body 3. Then, one side of the sliding sleeve 52 is tightened towards the surface of the wooden template body 3. Next, the irregular pin 54 is knocked from the limiting groove 55 on the surface of the sliding sleeve 52. During the knocking process, the surface of the irregular pin 54 presses the limiting groove 55 in the sliding sleeve 52 and the pull rod 56, and the sliding sleeve 52 is continuously moved closer to the surface of the wooden template body 3. At this time, the clamping leg 53 and the sliding sleeve 52 support the bottom of the wooden template body 3 covering the surface of the vertical column 1 to prevent the wooden template body 3 from falling off the surface of the vertical column 1.

[0034] After the wooden formwork body 3 is assembled and reinforced, concrete is injected into the grouting chamber between the vertical column 1 and the wooden formwork body 3. The concrete in the grouting chamber is continuously vibrated to ensure that the cement is fully concentrated at the required grouting position. During the vibration process, the concrete compresses the wooden formwork body 3, causing it to tilt outward. At the same time, the worker needs to pull the handle 410 to overcome the resistance of the spring 45 on the outside of the blocking block 44. The blocking block 44 compresses the spring 45 and moves in the direction of the handle 410. During the movement, the sliding plate 49 releases the obstruction of the limiting block 47 inside the operating plate 46. The sliding plate 49 slides downward in the operating plate 46. While sliding downward along the second vertical sliding groove 48 on both sides of the operating plate 46, the sliding plate 49 also slides into the wooden formwork. The main body 3 is moved in the opposite direction of tilting, and the pressing plate 413 is moved towards the tilted position of the wooden template main body 3. When the wooden template main body 3 is moved to a horizontal and vertical state with the surface of the vertical column 1, the handle 410 is released. The handle 410 is pulled back to its original position by the reaction force of the spring 45. After the cement dries, the irregular pin 54 is knocked from the sliding sleeve 52 from bottom to top. During the knocking process, the irregular pin 54 is taken out to release the restriction on the wooden template main body 3. Then, the handle 410 is slid out from the surface of the limiting block 47, and the pressing plate 413 and the pressing base 414 are formed into a folding state. Then, the elastic support strip 412 is pulled out from the inside of the limiting sleeve 411, and the pressing plate 413 and the pressing base 414 are formed into a horizontal state, completing this reinforcement construction.

[0035] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
