An adjustable auxiliary device for beam reinforcement binding

Abstract

This utility model discloses an adjustable auxiliary device for beam rebar tying, including an upper pressure-bearing component, a middle connecting component, a lower pressure-bearing component, a hydraulic mechanism, and a restraint mechanism. The lower pressure-bearing component includes a horizontally arranged base connecting plate and two vertical second outer tubes, which are respectively arranged on the surfaces of both ends of the base connecting plate. This utility model can adjust the support height of beam rebar tying according to the actual site conditions. After the beam rebar is tied and the pads at the bottom of the beam rebar are placed, the restraint mechanism at the inner tube connecting the middle connecting component and the second outer tube of the lower pressure-bearing component is opened, and the pressure relief valve of the hydraulic mechanism is opened, allowing the middle connecting component and the upper pressure-bearing component to slowly descend. When the bottom of the beam rebar contacts the pads, the device can descend a further distance to remove the device that is no longer under the pressure of the rebar, thus reducing the impact on the beam formwork during the lowering of the rebar cage.

Description

Technical Field

[0001] This utility model relates to the field of auxiliary technology for beam reinforcement binding, specifically an adjustable auxiliary device for beam reinforcement binding. Background Technology

[0002] In the construction of main structures, especially in the reinforcement binding of large-span beams, workers typically rely on simple tools to partially support the beam reinforcement cage for binding. This method carries the risk of tools tilting, falling, or breaking, potentially causing injury to workers. Furthermore, the erection and dismantling process is labor-intensive and time-consuming, with significant limitations. With the increase in high-rise and super high-rise buildings, beam and slab cross-sections have increased, and the reinforcement of large-section beams is complex and dense, making construction difficult and binding reinforcement within the formwork according to specifications challenging. Currently, most projects adopt the method of binding beam reinforcement above the formwork in advance, using tools such as timber and scaffolding supports to temporarily support the beam reinforcement. After the entire beam reinforcement is bound, the supports are removed, and the beam reinforcement is lowered manually. While this method ensures the binding of the beam reinforcement, it carries certain dangers, easily leading to collisions between the beam reinforcement and the formwork, causing formwork breakage or reinforcement bending and deformation, damaging construction, and affecting construction efficiency and results.

[0003] Chinese invention patent CN102979311B, with an authorization announcement date of April 1, 2015, discloses an auxiliary device for tying reinforcing bars in reinforced concrete beams and its application. The device mainly consists of two parallel telescopic supports and a crossbar spanning the two supports. The inner and outer tubes are connected by pins inserted into through holes in both. The fixing components include a base and a sleeve fixed to the base. Three to four reinforcing strips are welded around the base, and wooden pads are provided below the base. The connecting base consists of a pressure plate and limiting rods located at both ends of the pressure plate.

[0004] The support frame proposed in this invention patent is simple in design and easy to operate, and can effectively meet the needs of assisting in the binding of beam reinforcement. However, the invention has the following drawbacks: when the beam reinforcement is lowered, the support frame is not easy to remove from the reinforcement cage, and the buffering force generated during the lowering of the reinforcement cage is large, which may cause impact on the beam formwork, potentially leading to displacement or damage of the formwork, thereby affecting the thickness of the protective layer at the bottom and sides of the beam and reducing the quality of beam construction. Utility Model Content

[0005] The purpose of this invention is to provide an adjustable auxiliary device for tying beam reinforcement bars, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an adjustable beam reinforcement binding auxiliary device, comprising an upper pressure-bearing component, a middle connecting component, a lower pressure-bearing component, a hydraulic mechanism, and a restraint mechanism. The lower pressure-bearing component includes a horizontally arranged base connecting plate and two vertical second outer tubes, the two second outer tubes being respectively disposed on the surfaces at both ends of the base connecting plate. The middle connecting component includes two vertical inner tubes, a crossbar is provided between the two inner tubes, a support rod is provided at the center of the lower side of the crossbar, and the inner tubes are inserted into the top of the second outer tubes.

[0007] The upper pressure-bearing component includes two vertical first outer tubes, with a crossbeam between the two first outer tubes, and the first outer tubes are sleeved on the inner tube;

[0008] The hydraulic mechanism is located at the center of the surface of the base connecting plate, and the output end of the hydraulic mechanism is connected to the bottom of the support rod.

[0009] Both the bottom of the first outer tube and the top of the second outer tube are provided with a locking mechanism.

[0010] The second outer tube has two symmetrical diagonal bracing plates on its outer side.

[0011] The upper side of the crossbeam is provided with three arc-shaped grooves.

[0012] The first outer tube and the second outer tube have the same inner diameter, and the inner diameter of the first outer tube and the second outer tube is larger than the outer diameter of the inner tube.

[0013] Locking notches are provided on one side of the bottom opening of the first outer tube and one side of the top opening of the second outer tube.

[0014] The constraint mechanism includes a clamp fitted onto the locking notch, and the opening of the clamp is connected via a quick-release wrench.

[0015] The quick-release wrench has a bolt at its tail, and a nut is threaded onto the end of the bolt.

[0016] The hydraulic mechanism is a jack fixedly installed at the center of the surface of the base connecting plate, and the output end of the jack is fixedly connected to the bottom of the support rod.

[0017] The jack has a pressure rod on one side and a pressure relief valve at the bottom of the front side.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] This invention integrates the inner tube of the middle connecting component with the second outer tube of the lower pressure-bearing component. A hydraulic mechanism lifts the middle connecting component to a certain height, and a constraint mechanism then tightly connects the inner tube and the second outer tube. The inner tube of the middle connecting component is then integrated with the first outer tube of the upper pressure-bearing component. The height of the upper pressure-bearing component is adjusted according to the actual site conditions, and the constraint mechanism again tightly connects the inner tube and the first outer tube. This allows for adjustment of the support height for the beam reinforcement binding according to the actual site conditions. After the beam reinforcement binding is completed and the pads at the bottom of the beam reinforcement are placed, the constraint mechanism connecting the inner tube of the middle connecting component and the second outer tube of the lower pressure-bearing component is opened, and the pressure relief valve of the hydraulic mechanism is opened, allowing the middle connecting component and the upper pressure-bearing component to slowly descend. When the bottom of the beam reinforcement contacts the pads, the device can descend a further distance to remove the device detached from the reinforcement pressure, thus reducing the impact on the beam formwork during the lowering of the reinforcement cage.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0028] Please see Figure 1-6 This utility model provides a technical solution: an adjustable beam reinforcement binding auxiliary device, including an upper pressure-bearing component, a lower pressure-bearing component 30, a hydraulic mechanism 40 and a restraint mechanism 50. The hydraulic mechanism is installed between the lower pressure-bearing component and the upper pressure-bearing component. The hydraulic mechanism drives the upper pressure-bearing component to move in the vertical direction. The upper pressure-bearing component is provided with multiple arc-shaped grooves in the horizontal direction. The arc-shaped grooves are used to place the steel pipes supporting the beam reinforcement cage.

[0029] Furthermore, the lower pressure-bearing component 30 includes a horizontally arranged base connecting plate 32 and two vertical second outer tubes 31, with the two second outer tubes 31 respectively arranged on the surfaces at both ends of the base connecting plate 32;

[0030] Furthermore, the upper pressure-bearing assembly includes an upper pressure-bearing member 10 and a middle connecting member 20. The middle connecting member 20 includes two vertical inner tubes 21, with a crossbar 22 between the two inner tubes 21. A support rod 23 is provided at the center of the lower side of the crossbar 22. The inner tubes 21 are inserted into the top of the second outer tube 31, and the bottom of the inner tubes 21 is inserted into the top of the second outer tube 31, thereby assembling the middle connecting member 20 onto the lower pressure-bearing member 30.

[0031] The upper pressure-bearing member 10 includes two vertical first outer tubes 11, with a crossbeam 12 between the two first outer tubes 11. The first outer tubes 11 are sleeved on the inner tube 21. After the middle connecting member 20 is assembled on the lower pressure-bearing member 30, the first outer tubes 11 are sleeved on the inner tube 21, thereby assembling the upper pressure-bearing member 10 on the middle connecting member 20.

[0032] Furthermore, the hydraulic mechanism 40 is located at the center of the surface of the base connecting plate 32, and the output end of the hydraulic mechanism 40 is connected to the bottom of the support rod 23; the hydraulic mechanism 40 is used to lift the middle connecting member 20.

[0033] The bottom of the first outer tube 11 and the top of the second outer tube 31 are both provided with a locking constraint mechanism 50. The inner tube 21 of the middle connecting member 20 and the second outer tube 31 of the lower pressure-bearing member 30 are sleeved together. The middle connecting member 20 is lifted by the hydraulic mechanism 40 to a certain height, and then the constraint mechanism 50 is used to tightly connect the inner tube 21 and the second outer tube 31 together.

[0034] The inner tube 21 of the middle connecting member 20 is fitted together with the first outer tube 11 of the upper pressure-bearing member 10. The height of the upper pressure-bearing member 10 is adjusted according to the actual site conditions. Then, the restraint mechanism 50 is used to tightly connect the inner tube 21 and the first outer tube 11 together.

[0035] The second outer tube 31 is provided with two symmetrical diagonal bracing plates 33. The diagonal bracing plates 33 are right-angled triangles. The right-angled side at the bottom of the diagonal bracing plate 33 is on the same horizontal plane as the lower surface of the base connecting plate 32, which increases the stability of the bottom support of the second outer tube 31.

[0036] Among them, three arc-shaped grooves 13 are evenly provided on the upper side of the crossbeam 12. The arc-shaped grooves 13 are used to place the steel pipes of the support beam reinforcement cage. In actual use, the steel pipes of the support beam reinforcement cage are placed in the arc-shaped grooves 13.

[0037] The first outer tube 11 and the second outer tube 31 have the same inner diameter, and the inner diameter of the first outer tube 11 and the second outer tube 31 is larger than the outer diameter of the inner tube 21. The outer diameter of the inner tube 21 is 2-4 mm smaller than the inner diameter of the first outer tube 11 and the second outer tube 31, which makes it easier to insert the bottom of the inner tube 21 into the top of the second outer tube 31, and also makes it easier to put the first outer tube 11 on the inner tube 21.

[0038] The first outer tube 11 has a locking notch on one side of the bottom opening and the second outer tube 31 has a locking notch on one side of the top opening. When the restraint mechanism 50 is locked, the opening at the bottom of the first outer tube 11 will shrink due to the presence of the locking notch, thereby locking the position of the first outer tube 11 on the inner tube 21; the opening at the bottom of the second outer tube 31 will shrink due to the presence of the locking notch, thereby locking the connection between the inner tube 21 and the second outer tube 31.

[0039] The restraint mechanism 50 includes a clamp 51 fitted into the locking notch. The opening of the clamp 51 is connected by a quick-release wrench 54. When it is necessary to loosen the restraint mechanism 50, the quick-release wrench 54 can be directly pulled to quickly loosen the restraint mechanism 50.

[0040] The quick-release wrench 54 has a bolt 52 at its tail, and a nut 53 is threaded onto the end of the bolt 52. The constraint mechanism 50 can also be loosened by loosening the nut 53.

[0041] The hydraulic mechanism 40 is fixedly installed on the jack 41 at the center of the surface of the base connecting plate 32. The output end of the jack 41 is fixedly connected to the bottom of the support rod 23. A pressure rod 42 is provided on one side of the jack 41, and a pressure relief valve 43 is provided at the bottom of the front of the jack 41. The jack 41 can be driven to work through the pressure rod 42. Then, the middle connecting member 20 is lifted by the jack 41 to a certain height. After the beam reinforcement is tied and the pads at the bottom of the beam reinforcement are placed, the constraint mechanism 50 at the second outer tube 31 of the inner tube 21 of the middle connecting member 20 and the lower pressure bearing member 30 is opened. Then, the pressure relief valve 43 of the hydraulic mechanism 40 is opened, so that the middle connecting member 20 and the upper pressure bearing member 10 slowly descend.

[0042] More specifically, the specific operating steps for using the adjustable beam reinforcement binding auxiliary device of this application are as follows:

[0043] Step 1: Connect the inner tube 21 of the middle connecting member 20 with the second outer tube 31 of the lower pressure-bearing member 30. Then, drive the jack 41 to work through the lower pressure rod 42. Lift the middle connecting member 20 to a certain height through the jack 41. Then, use the constraint mechanism 50 to tightly connect the inner tube 21 and the second outer tube 31 together.

[0044] Step 2: Connect the inner tube 21 of the middle connecting member 20 to the first outer tube 11 of the upper pressure-bearing member 10. Adjust the height of the upper pressure-bearing member 10 according to the actual site conditions, and then use the restraint mechanism 50 to tightly connect the inner tube 21 and the first outer tube 11 together.

[0045] Step 3: Repeat steps 1 and 2 to adjust one auxiliary device. Place the two auxiliary devices on both sides of the beam reinforcement. Place the steel pipe on the arc-shaped groove 13 of the upper bearing member 10 of the two devices. Up to 3 steel pipes can be placed to increase the contact area. The steel pipe should pass under the uppermost longitudinal reinforcement of the beam.

[0046] Step 4: After the beam reinforcement is tied and the pads at the bottom of the beam reinforcement are placed, loosen the quick-release wrench 54 on the constraint mechanism 50 that connects the inner tube 21 and the second outer tube 31, and then open the pressure relief valve 43 to release the pressure of the jack 41. Then the device will slowly descend. When the bottom of the beam reinforcement contacts the pads, the device can descend a further distance to facilitate the removal of the device that is no longer under the pressure of the reinforcement.

[0047] Step 5: When the used device is used for tying the reinforcing bars of beams of the same size, the height can be quickly adjusted through the constraint mechanism 50. In this case, step 2 can be omitted.

[0048] The restraint mechanism 50 can be used to tighten the nut 53 with an electric wrench. Before using the electric wrench, the quick-release wrench 54 should be fastened. If the nut 53 is tightened manually with a wrench, the quick-release wrench 54 should be disengaged before tightening, and then closed after the nut 53 is tightened with the wrench.

[0049] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
