Description

Technical Field

[0001] The utility model relates to the technical field of building construction equipment, in particular to a high-efficiency adjusting device for building beam and slab support top screws. Background Art

[0002] At present, building top screws are widely used in construction engineering to adjust the bottom of the template beam, the elevation and flatness of the top plate. The building top screws are divided into top screws and top screw nuts.

[0003] The elevation and flatness of the bottom of the beam and the top plate affect the cross-sectional dimensions of the structural beams and floor slabs, the horizontality of the structural top plate, the building floor height, etc. Adjusting the bottom of the building beam and the top plate to ensure that the flatness of the structural top plate meets the standard plays a vital role in the construction process of the building project.

[0004] The traditional method of adjusting the bottom of the beam and the top plate requires manual knocking of the top screw nut to rotate and drive the top screw rod to rotate and raise or lower the top screw due to the fact that the building top screw is stuck under the force. Due to the different building heights, especially the tall spatial structure of public buildings, workers need to climb up and down many times to adjust the top screw during construction. The top screw adjustment process is complicated and requires a lot of manpower and material resources for repeated adjustments. The construction process of the top plate top screw adjustment is cumbersome, the labor intensity of workers is high, and the construction efficiency is low. Utility Model Content

[0008] Preferably, the transmission direction changer includes a shell, a rotating knob is provided through the shell, the rotating knob passes through the side of the shell, one end of the rotating knob is located in the shell and is fixedly connected to an input gear, a fixed gear is rotatably connected in the shell, the fixed gear is fixedly sleeved on the frame rod, and the fixed gear is engaged with the input gear.

[0009] Preferably, the fixed gear and the input gear are both bevel gears.

[0010] Preferably, the telescopic adjustment device includes several thick telescopic rods, several of the thick telescopic rods are fixedly connected to the top surface of the shell, and the top ends of several of the thick telescopic rods are fixedly connected to a fixer at the same time. The thick telescopic rods are hollow structures, and a thin telescopic rod is slidably connected inside each of the thick telescopic rods.

When the rotating knob is rotated, because the gear is fixedly connected to the frame rod and cannot move and rotate, the rotation of the rotating knob will drive the entire outer shell to rotate around the outer shell, which will be transmitted to the connecting member through the telescopic adjustment device. Because the connecting member and the top screw are threadedly connected, the rotation of the connecting member will be converted into a vertical linear motion of the top screw through the thread, thereby controlling the top screw to move up and down and adjust the support height of the top screw. This adjustment can be achieved through the rotation direction changer located at a low position, so that the height of the top screw can be adjusted without the need to climb to the position of the top screw with the help of a ladder. The adjustment method is simple and easy to operate, which can greatly save workload and improve work efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0018] The following will be combined with specific embodiments and attached Figure 1-4 , clearly and completely describe the technical solutions in the embodiments of the present utility model.

[0019] A high-efficiency adjustment device for the top screw of a building beam and slab support includes a rack rod 1, which is fixedly connected to the ground. The rack rod 1 is the supporting base of the integral top screw 2. The rack rod 1 is a central control structure. A top screw 2 is connected to the rack rod 1 for sliding from top to bottom. The outer diameter of the top screw 2 is smaller than the inner diameter of the rack rod 1. The top screw 2 can slide freely in the vertical direction relative to the rack rod 1, but it cannot rotate. A connecting member 4 is rotatably connected to the top of the rack rod 1. The connecting member 4 can rotate freely relative to the rack rod 1, but the connecting member 4 will not separate from the top of the rack rod 1. Its specific structure is that a slide groove 41 is opened on the outer periphery of the top of the rack rod 1, and the inner side surface of the connecting member 4 corresponds to the slider 42. The slider 42 is locked. The sliding groove 41 can keep it rotatingly connected. The inner side of the connecting member 4 is provided with an internal thread, and the outer surface of the top screw 2 is provided with an external thread matching the internal thread, so that the connecting member 4 can be threadedly connected to the top screw 2. A transmission component 3 is fixedly connected to the frame rod 1. One end of the transmission component 3 is fixedly connected to the frame rod 1, and the other end of the transmission component 3 is detachably connected to the connecting member 4. After assembly, the transmission component 3 is fixed to the connecting member 4, so the connecting member 4 can be adjusted by controlling the lower end of the transmission component 3. There is no need to adjust the connecting member 4 at the top of the frame rod 1 after climbing, which reduces the complexity of adjusting the top screw on the connecting member 4 and is conducive to improving work efficiency.

[0020] The transmission assembly 3 includes a transmission direction changer 31, which is fixedly arranged on the rack 1. The transmission direction changer 31 includes a shell 311.

The rotation knob 312 is rotatably connected to the shell 311. One end of the rotation knob 312 located inside the shell 311 is fixedly connected to an input gear 313. The input gear 313 can be rotated as needed. The rotation of the knob 312 causes the rotation, and a fixed gear 314 is rotatably connected in the housing 311. The fixed gear 314 can rotate freely relative to the housing 311. The fixed gear 314 is coaxially arranged with the housing 311. The axis of the fixed gear 314 is perpendicular to the axis of the input gear 313. The fixed gear 314 is fixedly sleeved on the frame rod 1. The fixed gear 314 is meshed with the input gear 313. The fixed gear 314 and the input gear 313 are both oblique bevel gears, and the transmission is stable.

[0021] The cam 324 is fixedly connected to the top of the housing 311, and the cam 325 is fixedly connected to the top of the housing 311. The cam 324 includes three thick telescopic rods 321, and the three thick telescopic rods 321 are fixedly connected to the top surface of the housing 311. The top of the thick telescopic rod 321 is also fixedly connected to a fixer 323. The fixer 323 limits and fixes the three thick telescopic rods 321 so that they can ensure that they are parallel to each other and will not bend. The thick telescopic rod 321 is a hollow structure. A thin telescopic rod 322 is slidably connected in each of the thick telescopic rods 321. The fixer 323 can fix the thick telescopic rod 321 and the thin telescopic rod 322. The fixer 323 is a prior art and its detailed structure is omitted here. The top of the thin telescopic rod 322 is commonly fixedly connected to a connecting plate 324. Two insertion rods 325 are fixedly provided on the top surface of the connecting plate 324. The insertion rods 325 are used to be assembled and connected with the connecting member 4.

[0022] The side of the connecting member 4 is fixedly connected to two assembly plates 43, each assembly plate 43 is provided with a socket 44 corresponding to the plug rod 325, which facilitates the telescopic adjustment device 32 to be connected to the plug rod 325 and the socket 44.

[0023] The plurality of connecting plates 324 and the connecting member 4 are detachably connected.

[0024] When the cam 314 is in the upright position, the lever 318 is rotated to move the lever 314 downwards, and the lever 316 is in the upright position, so that the lever 318 can move upwards and downwards, thereby reducing the tension of the lever 314.

[0025] Except for the technical features described in the specification, all other technical features are known technologies to those skilled in the art.

[0026] In the present invention, "up", "down", "left", "right", "front" and "back" are relative positions used to conveniently describe positional relationships, and therefore cannot be understood as absolute positions to limit the scope of protection.

[0027] The above content is merely an example and explanation of the structure of the present utility model.
