Description

Technical Field

[0001] This utility model belongs to the field of concrete vibration technology, specifically relating to a concrete vibration air-entraining plate. Background Technology

[0002] During the construction of concrete structures, especially in areas with dense reinforcement and on the outer vertical sides, particularly the inner sloping sides, traditional circular vibrators often struggle to penetrate the narrow gaps between the reinforcement and the formwork. Furthermore, during the vibrator's lifting process, air bubbles generated in the concrete come into contact with the side formwork and accumulate on its surface, especially on the inner sloping side formwork, where this accumulation is more pronounced. This results in numerous air bubbles, pitting, and other surface defects on the concrete structure, severely impacting its appearance quality. To address these issues, there is an urgent need to develop a construction device that combines vibration and air entrainment functions to improve the quality of concrete vibration. Utility Model Content

[0003] This invention addresses the problem of insufficient space in narrow gaps, which limits the use of ordinary circular vibrators, and the fact that ordinary circular vibrators cannot expel air bubbles from inside the concrete.

[0004] This utility model provides the following technical solution: a concrete vibration air-entraining plate, comprising a vibration air-entraining plate, one end of the vibration air-entraining plate in the length direction being an insertion end inserted into the concrete, and the other end being a connection end connected to a vibration motor; air-entraining holes are distributed between the insertion end and the connection end of the vibration air-entraining plate.

[0005] Furthermore, the air intake hole is an elongated hole parallel to the length direction of the vibrating air intake plate.

[0006] Furthermore, along the length of the vibrating air-inducing plate, the air-inducing holes are distributed in a straight line at intervals; along the width of the vibrating air-inducing plate, the air-inducing holes in rows are distributed at intervals, with the air-inducing holes in adjacent rows staggered.

[0007] Furthermore, the insertion end of the vibratory air-purifying plate is a pointed tip that gradually narrows from both sides towards the middle.

[0008] Furthermore, the connecting end of the vibratory air-expelling plate is connected to the force-transmitting vibratory rod on the vibratory motor via two first bolts.

[0009] Furthermore, the vibratory motor includes a main handle, a secondary handle, and a rubber buffer connecting sleeve; the main handle is fixed to the tail of the vibratory motor; The top cap of the rubber buffer connecting sleeve is located between the vibration motor and the auxiliary handle, and the three are connected together by a second bolt; the force transmission vibration rod is connected to the rubber buffer connecting sleeve by a socket.

[0010] Furthermore, a clamp is fitted onto the rubber buffer connecting sleeve, which securely connects the rubber buffer connecting sleeve and the force-transmitting vibration rod.

[0011] Furthermore, the start / stop switch for the vibration motor is located on the main handle.

[0012] Furthermore, the two first bolts are arranged one in front of the other along the length of the vibratory air-expelling plate.

[0013] Compared with the prior art, the advantages of this utility model are: This utility model provides a concrete vibration air-entraining plate, which improves the traditional round vibrator into a thin plate-shaped vibration air-entraining plate with a width of less than or equal to 8cm. It can be easily inserted into the narrow gap between the reinforcing bars and the formwork (the common spacing between reinforcing bars is 10cm). It effectively solves the problem that traditional vibration equipment is difficult to intervene in complex working conditions such as areas with dense reinforcing bars, vertical side formwork and inner inclined side formwork.

[0014] The vibratory air-entraining plate has a large number of regularly distributed elongated air-entraining holes. Under vibration, utilizing the principle of pressure difference, air bubbles in the concrete can be actively captured and guided into the air-entraining holes. During the process of raising and lowering the vibratory air-entraining plate, these air bubbles can be directly carried out of the concrete body, thereby significantly reducing appearance defects such as air bubbles and pitting on the surface of the structure from the source, and greatly improving the appearance quality of the concrete.

Detailed Implementation

[0017] To more clearly illustrate the technical solutions in the embodiments of this utility model or the prior art, the drawings used in the description of the embodiments or the prior art will be briefly introduced below. Obviously, the drawings described below are only some embodiments of this utility model. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0018] like Figure 1 , Figure 2As shown: A concrete vibratory air-entraining plate includes a vibratory air-entraining plate 1, one end of which is an insertion end 1.1 inserted into the concrete, and the other end is a connection end 1.2 connected to a vibratory motor 2; air-entraining holes 1.3 are distributed between the insertion end 1.1 and the connection end 1.2 of the vibratory air-entraining plate 1.

[0019] The vibratory air-inducing plate 1 is made into a thin plate shape, so that it can be inserted into the narrow space between the formwork and the reinforcing bars. Most of the reinforcing bars are spaced 10cm apart. To prevent the plate from being unable to be inserted due to the reinforcing bars, the width of the vibratory air-inducing plate 1 is less than or equal to 8cm.

[0020] The air intake hole 1.3 is an elongated hole parallel to the length direction of the vibrating air intake plate 1. The width of the air intake hole 1.3 is 1cm and the length is 10~15cm.

[0021] Along the length of the vibrating air-inducing plate 1, the air-inducing holes 1.3 are distributed in a straight line at intervals; along the width of the vibrating air-inducing plate 1, the air-inducing holes 1.3 are distributed in rows at intervals, with adjacent rows of air-inducing holes 1.3 staggered. Air bubbles are introduced into the air-inducing holes 1.3 using a pressure difference. The vibrating air-inducing plate 1 is inserted along the side mold of the template. Driven by the vibrating motor 2, the vibrating air-inducing plate 1 vibrates, accelerating and promoting the entry of air bubbles into the air-inducing holes 1.3. As the vibrating air-inducing plate 1 is lifted upwards, the air bubbles in the concrete are carried out. With the reciprocating insertion and withdrawal of the vibrating air-inducing plate 1, the air bubbles in the concrete are gradually expelled.

[0022] The insertion end 1.1 of the vibratory air-entraining plate 1 is a pointed tip that gradually narrows from both sides to the middle, reducing resistance and facilitating insertion into the concrete.

[0023] The connecting end 1.2 of the vibratory air-inducing plate 1 is connected to the force-transmitting vibratory rod 2.1 on the vibratory motor 2 via two first bolts 3. The two first bolts 3 are arranged one in front of the other along the length of the vibratory air-inducing plate 1. The vibratory motor 2 is used to provide vibration power to the force-transmitting vibratory rod 2.1 and the vibratory air-inducing plate 1.

[0024] The vibratory motor 2 includes a main handle 2.2, an auxiliary handle 2.3, and a rubber buffer connecting sleeve 2.4. The main handle 2.2 is fixed to the tail of the vibratory motor 2. The rubber buffer connecting sleeve 2.4 is made of rubber and serves to buffer vibration and connect the vibratory motor 2 and the force-transmitting vibratory rod 2.1. The top cap of the rubber buffer connecting sleeve 2.4 is located between the vibratory motor 2 and the auxiliary handle 2.3, and the three are connected together by a second bolt 2.5. The force-transmitting vibratory rod 2.1 is socketed to the rubber buffer connecting sleeve 2.4. A clamp 4 is fitted on the rubber buffer connecting sleeve 2.4, which securely connects the rubber buffer connecting sleeve 2.4 and the force-transmitting vibratory rod 2.1.

[0025] The main handle 2.2 and the auxiliary handle 2.3 are used together to move the concrete vibrating air plate up, down, left, and right, facilitating on-site construction. The start / stop switch for the vibrating motor 2 is located on the main handle 2.2 for easy operation. Pressing the start / stop switch starts the vibrating motor 2; releasing the start / stop switch stops the vibrating motor 2.
