The present invention relates to a building mortar coating device for applying mortar to the inner and outer surfaces of the wall at the time of construction.

In general, in the construction, after the construction of the frame and the wall, such as mortar is applied to the surface of the plastering work to obtain a smooth surface, such mortar coating work was mainly performed by a skilled plasterer using a trowel. Bars, which require a lot of manpower and time, have been proposed such as Utility Model Publication No. 84-1671 (automatic cement mortar applicator) and 92-2704 (wall plasterer). There is a problem such as that was not practical.

In other words, Utility Model Publication No. 84-1671 had the problem of periodically replenishing the mortar supplied to the inlet barrel and the need to stop the equipment at each refill, as well as the pressurizing screw and the pressurized mortar in the inlet cylinder. The roller was supplied to the upper and lower outlets so that the supply amount was not uniform, so that the coating was not uniform. Moreover, when the viscosity of the mortar was high, the outlets were frequently blocked, and the mortar supplied to each outlet was As the roller is applied from the lower side, the surface is not smooth, and as the upper and lower sides of the application are completed, a boundary line is created on the applied surface. Motors for motors are installed separately to match the flow of mortar It was very difficult to match the ascending and descending speed of the inlet barrel, which resulted in an uneven coating condition, which forced the final finishing plastering operation to depend on manpower, and Utility Model Publication No. 92-2704 had a large number of chain driven inside the rectangular body. By installing the blade piece, the mortar supplied to the inlet of one side is supplied to the other side, and the plastering piece installed at the end is used to perform the plastering work as the gas rises, which is a gas lifting motor and a blade piece driving motor. As it is installed separately, it is very difficult to match the lifting speed of the gas according to the amount of mortar discharged, so that the coating state is uneven. The mortar applied becomes uneven, After curing, the low-density part was accompanied with a serious problem of being easily destroyed even by a weak impact.In addition, by using a plurality of motors, both the former and the latter increased the manufacturing cost of the equipment and wasted power due to driving. In particular, when the mortar is applied, the equipment is tilted by the reaction force generated between the wall and the inlet barrel or gas, so that the mortar-coated surface could not be perpendicular to each other. The mortar is integrated in the driving unit, so if the driving state becomes unstable or severe, the driving becomes impossible and the components of the component are damaged.

The present invention has eliminated all such problems, and the components are driven by a single motor so that the mortar can be uniformly supplied and coated, and the density of the mortar to be applied can be uniformly and precisely applied. If it is described in detail with reference to the accompanying drawings as follows.

Frames 2a and 2b are installed upright on the substrates 1a and 1b at regular intervals on both sides, so that the gap retaining rods 3 are installed on the upper side, and the support bars 4a and 4b are installed on the back side. The racks 5a and 5b are installed on the front surface to allow the lifting body 9 to be lifted and lowered by pinions 29a and 29b engaged thereto.

The boards 1a, 1b and support rods 4a and 4b are freely provided with support bars 7a and 7b having fixing rings 8a and 8b, and the support rods 4a and (b) directly above them. 4b) and install the angle adjustment bolt (6a) (6b).

The forward / reverse rotation motor 11 and the gear box B are installed outside the center of the case 10 of the lifting body 9, and guide rollers Ra and Rb are provided on both sides.

In the gearbox B, the main gear 12 and the reduction gear 14 are integrally fixed to the main shaft 12 of the forward / reverse rotation motor 11 to the reduction gears 14 'and 14``. By interlocking the low speed gear 15, the sprocket 16 is coaxial with the low speed gear 15, and the high speed gear 17 is interlocked with the main gear 13, but the sprocket 18 on the coaxial Farm).

The shaft 9 is provided with four shafts 19, 20, 21 and 22, and the sprockets 23 and 24 at one end of each shaft 19, 20, 21 and 22. 25) 26 to pinch the upper side 21, 22 and the lower side 19, 20 to be interlocked with each other chain 28, 27, pinion on both sides of the lower outer shaft 19 (29a) (29b) and the sprocket 30 in a position corresponding to the sprocket 16 of the gearbox (B) to be condensed to be interlocked with the chain 31, the gear box on the upper outer shaft 21 The sprocket 32 is fixed to the position corresponding to the sprocket 18 of (B) so as to be interlocked with the chain 33, and bevel gears 34a and 34b are provided at one end of the shaft 21 to form an upright shaft ( 35 is interlocked, and the sprocket 36b is installed on the upright shaft 35 so as to interlock with the sprocket 36a on the other side and the chain 37, and the hook 39 is connected to one side of the chain 37. To 38).

The latch 39 is flow-installed in the guide hole 41 of the movable opening 40 installed above the case 10, and installs the holder 42 in the center of the movable opening 40.

The upper and lower inner shafts 22 and 20 of the lifting body 9 are provided with a square roller 43 and an annular roller 44, respectively, and a plasterboard 45 having an appropriate angle at the lower end of the case 10. This is done by installing

In the figure, reference numeral 46 denotes a supply hose to which mortar is supplied from a conventional pump car, 47 is a wall, 48 is ground, and 49 is a pile.

According to the present invention configured as described above, the pile 49 is placed on the ground 48 through the fixing rings 8a and 8b by being positioned at the place where the substrates 1a and 1b are installed. If the installation is completed, if the vertical position of the frame (2a) (2b) does not fit in the installed state if you operate the angle adjusting bolt (6a) (6b), the brace rod (7a) (7b) acts as a lever Since the inclination of the supporting rods 4a and 4b is adjusted, the vertical state of the frames 2a and 2b is precisely calibrated, and then the power in the forward direction is connected to the forward and reverse rotation motors 11. As shown in FIG. 2, FIG. 3, and FIG. 6, the main gear 13 on the main shaft 12 rotates to transmit the high speed rotational force in the reverse direction to the high speed gear 17, and to the low speed gear 15. The high speed gear 17 and the low speed gear 1 are transferred to the low speed rotational force in the same direction as the main gear 13 via the 14 and 14'14. 5, the sprockets (18) and (16) coaxially condensed to the sprockets (25), (26), (23), (24) and the squares (32) (28) (31) (27) respectively. The rollers 43 and the annular rollers 44 have high speed and low speed rotation in the same direction as the gears 17 and 15, and at the same time, the pinions 29a and 29b fixed to the shaft 19 are rotated so that the rack ( 5a, 5b, as well as ascend, as well as the upright shaft 35, which is interlocked with the bevel gears 34a and 34b on the shaft 21, while rotating the sprocket 36b stuck to it by rotating the sprocket 36a on the other side In order to rotate the chain 37 in conjunction with the), as shown in Figures 4 and 5 of the figure, the locking mechanism 39, which is addressed to the link 38 on one side of the chain 37, the moving port 40 While guiding the guide hole 41 of the circumferential direction and reciprocating the moving hole 40 in the transverse direction to reciprocate the supply hose 46 fixed to the holder 42 between the wall 47 and the lifting body 9 To ensure that the mortar is uniformly supplied, the drawing As shown in FIG. 6, the square roller 43 pushes the mortar supplied from the supply hose 46 downward so that no empty space is generated, and the annular roller 44 presses a part of the mortar while pressing the surface side. To raise the density of the supplied mortar uniformly and precisely, so that the bottom plasterboard 45 rises, allowing the surface to be finished uniformly and smoothly, and the applied portion is struck or the wall 47 It is to be prevented from peeling off.

On the other hand, when the lifting body (9) is to rise to the highest point to further restrain the bar, which may limit the length of the rack (5a) (5b), of course, a conventional sensor (shown Can be stopped by stopping the forward / reverse rotation motor 11 by installing N / A).

Thus, after the application of the mortar is completed, the pile 49 is pulled out from the wall 47 through the fixing rings 8a and 8b, and the equipment itself is separated from the wall 47. When the reverse power is supplied to the reverse rotation motor 11, the pinions 29a and 29b are rotated in reverse to guide the racks 5a and 5b so that the lifting body 9 is lowered. In order to prevent the collision between the 9 and the substrates 1a and 1b, a normal sensor (not shown) may also be provided below.

In addition, in the drawings, the height of the frame (2a) (2b) is designed by setting the height to the height of the first floor that is commonly used in current construction, but if the height is formed higher, the wall 47 of the high height can be applied at once. Of course, it is possible to apply the mortar to the wall 47 of a high building by connecting a plurality of frames (2a, 2b) in the vertical direction in a single operation.

As described above, the present invention reduces the manufacturing cost and power by allowing each component to be driven by one motor, as well as maintaining a constant ratio of the mortar supply and the driving speed to uniformly apply the mortar. In addition, the density of the mortar to be applied is densified to provide a great effect such as providing a beautiful appearance and durability after curing.
