Description

Technical Field

[0001] The invention relates to the technical field of assembled stairs, and in particular to grouting equipment for assembled structure stairs. Background Art

[0002] Prefabricated buildings are a form of construction that the country has vigorously advocated and promoted in recent years, among which prefabricated stairs are the most commonly used prefabricated components.

[0003] At present, during the installation of prefabricated stairs, it is necessary to insert the steel bars on the rest platform into the installation holes on the stairs, and pour mortar into the installation holes to connect and fix the prefabricated stairs to the rest platform. The mortar pouring of the installation holes of existing prefabricated stairs is generally done manually, which has low efficiency and the mortar sets quickly, which easily causes the installation holes to be filled loosely. At the same time, if the mortar stirred each time is not used up quickly, it is easy to coagulate, resulting in material waste. Summary of the invention

[0004] The purpose of the present invention is to provide a grouting device for assembled structure stairs, which has the advantages of improving construction efficiency, increasing grouting density and saving materials.

[0005] The present invention is achieved through the following technical solutions:

[0006] A grouting device for assembled structure stairs comprises a grouting barrel, an upper end cover is arranged at one end of the grouting barrel, a piston is slidably arranged in the grouting barrel, a push rod is connected to the piston, and the push rod passes through the upper end cover and extends out of the grouting barrel; a lower end cover is arranged at one end of the grouting barrel away from the upper end cover, the lower end cover is detachably connected to the grouting barrel, and a grouting pipe connected to the inside of the grouting barrel is arranged on the lower end cover.

[0007] By adopting the above technical scheme, a grouting barrel is set, the slurry is set in the grouting barrel, and then the grouting pipe is inserted into the bottom of the installation hole, and the slurry in the grouting barrel is transported to the installation hole by using a piston, so that the slurry is grouted from the bottom to the top of the installation hole, thereby ensuring the density of the grouting of the installation hole. At the same time, the slurry is directly transported to the installation hole by using the grouting barrel, which is easy to operate and has high construction efficiency, avoids the slurry from solidifying before it is used up, causing it to be unusable, and avoids the slurry from spilling, thereby saving materials; and after the slurry is used up, the grouting barrel can be used as a mixing container to stir the slurry, which is more convenient.

[0008] The present invention is further configured as follows: the lower end cover is threadedly connected to the grouting barrel.

[0009] By adopting the above technical solution, the lower end cover and the grouting barrel can be easily installed and disassembled, thereby increasing the convenience of using the equipment.

[0010] The present invention is further configured as follows: the piston comprises an upper rubber pad, a lower rubber pad and a support plate arranged between the upper rubber pad and the lower rubber pad; the push rod passes through the upper rubber pad, the support plate and the lower rubber pad in sequence and is clamped and fixed by two fastening nuts.

[0011] By adopting the above technical solution, by setting the upper rubber pad and the lower rubber pad, it can be ensured that the piston pushes the slurry in the grouting barrel out of the grouting barrel when it moves, and then cooperates with the support plate to ensure the stability of the piston itself in the process of pushing the slurry, so as to avoid the rubber pad being soft and turning up in the process of pushing the slurry, resulting in the inability to push the slurry; at the same time, the piston and the push rod are detachably connected by the fastening nut, so that the piston and the push rod can be disassembled and cleaned after use, so as to avoid the slurry solidifying on the piston and affecting the next use.

[0012] The present invention is further configured as follows: the grouting pipe comprises a round tube portion and a flat tube portion, one end of the round tube portion is connected to the lower end cover, and the other end is connected to the flat tube portion.

[0013] By adopting the above technical scheme, the round tube part has a large diameter, which is convenient for conveying the slurry in the grouting tube to the installation hole. The flat tube part can be inserted between the installation hole and the steel bar, so that the grouting pipe can be grouting from the bottom to the top of the installation hole, ensuring the density of the grouting and improving the smoothness of the slurry delivery.

[0014] The present invention is further configured as follows: the upper end cover is threadedly connected to the grouting tube.

[0015] By adopting the above technical solution, the upper end cover and the grouting barrel are detachably connected by threads. After the grouting barrel is used, the upper end cover and the piston can be removed from the grouting barrel for cleaning, thereby preventing the slurry on the piston or the upper end cover from solidifying and affecting the next use.

[0016] The present invention is further configured such that a handle is provided at one end of the push rod away from the piston.

[0017] By adopting the above technical solution, the movement of the piston can be easily controlled through the handle, thereby increasing the convenience of operation.

[0018] The present invention is further configured as follows: it also includes a support frame, the support frame includes a support frame, a support leg is fixedly provided at the bottom of the support frame, a round tube support is provided on the grouting barrel, a supporting device for positioning the grouting barrel is fixedly provided on the support leg below the support frame, and the round tube support is placed on the supporting device to position the grouting barrel.

[0019] By adopting the above technical solution, during grouting, one end of the grouting barrel with the grouting pipe is inserted from the support frame into the support frame, and the two round tube supports are placed on the supporting device to position the grouting barrel, and then the grouting work is carried out, avoiding the staff from holding the grouting barrel all the time, which is more labor-saving and convenient.

[0020] The present invention is further configured as follows: the supporting device includes a supporting ring, the round tube support is placed on the supporting ring, cross braces are respectively fixedly provided between adjacent legs below the supporting frame, and fixing rods are respectively fixedly provided between the supporting ring and the cross braces.

[0021] By adopting the above technical solution, the round tube support is placed on the support ring to position the grouting tube, which makes the operation more convenient.

[0022] The present invention is further configured as follows: the support ring includes two semicircular ring units, the two ring units are fixedly connected to the cross brace rod through a fixing rod, and a channel is formed between the two ring units.

[0023] By adopting the above technical solution, when taking out the grouting tube, the grouting tube can be moved upwardly with an inclination, so that the grouting pipe can be moved out of the support ring by using the channel, thereby reducing the moving height of the grouting tube and increasing the convenience of operation.

[0024] The present invention is further configured such that pedals are fixedly provided at the bottoms of the supporting legs respectively.

[0025] By adopting the above technical solution, when stirring the slurry, two feet are stepped on the pedals to ensure the stability of the support frame.

[0026] In summary, the beneficial technical effects of the present invention are:

[0027] 1. By setting a grouting barrel, the slurry is set in the grouting barrel, and then the grouting pipe is inserted into the bottom of the installation hole, and the slurry in the grouting barrel is transported to the installation hole by the piston, so that the slurry is grouted from the bottom to the top of the installation hole, ensuring the density of the grouting of the installation hole.

DETAILED DESCRIPTION

[0035] The present invention is further described in detail below in conjunction with the accompanying drawings.

[0036] Reference Figure 1 , is a grouting device for assembled structure stairs disclosed by the present invention, comprising a grouting tube 1, which is a steel pipe with two ends opened, and the length of the grouting tube 1 is 300mm and the inner diameter is 70mm. An upper end cover 2 is arranged at one end of the grouting tube 1, and the upper end cover 2 is sleeved outside the grouting tube 1 and threadedly connected thereto; a piston 3 is slidably arranged inside the grouting tube 1, and the outer diameter of the piston 3 matches the inner diameter size of the grouting tube 1, and a push rod 4 is connected to the piston 3, and the end of the push rod 4 away from the piston 3 passes through the upper end cover 2 and extends outside the grouting tube 1, and the piston 3 is controlled to slide inside the grouting tube 1 by the push rod 4, so as to push the slurry in the grouting tube 1 out of the grouting tube 1. Furthermore, a handle 41 is fixedly installed at the end of the push rod 4 away from the piston 3, and the length of the handle 41 is 120mm, and forms a T-shaped structure with the push rod 4, and the movement of the piston 3 is conveniently controlled by the handle 41, thereby increasing the convenience of operation.

[0037] The piston 3 includes an upper rubber pad 31, a lower rubber pad 32 and a support plate 33 arranged between the upper rubber pad 31 and the lower rubber pad 32. The support plate 33 is a steel plate or an iron plate. The end of the push rod 4 close to the piston 3 passes through the upper rubber pad 31, the support plate 33 and the lower rubber pad 32 in sequence, and the three are clamped and fixed together by two fastening nuts. By setting the upper rubber pad 31 and the lower rubber pad 32, it can be ensured that the piston 3 pushes the slurry in the grouting tube 1 out of the grouting tube 1 when it moves, and then cooperates with the support plate 33 to ensure the stability of the piston 3 itself during the process of pushing the slurry, so as to avoid the rubber pad being soft and turning up during the process of pushing the slurry, resulting in the inability to push the slurry; at the same time, the piston 3 and the push rod 4 are detachably connected by the fastening nut, so that the piston 3 and the push rod 4 can be disassembled and cleaned after use to avoid the slurry solidifying on the piston 3 and affecting the next use.

[0038] A lower end cover 5 is provided at the end of the grouting tube 1 away from the upper end cover 2. The lower end cover 5 is sleeved on the outside of the grouting tube 1 and is detachably connected thereto. The detachable connection is preferably a threaded connection. A grouting pipe 6 is fixedly provided on the lower end cover 5. The grouting pipe 6 is a galvanized steel pipe with a diameter of 20 mm and a length of 330 mm. The grouting pipe 6 is connected to the interior of the grouting tube 1.

[0039] During the installation of the assembled staircase, the steel bars on the resting platform need to be inserted into the installation hole and then grouting is performed. Therefore, during grouting, the steel bars in the installation hole will affect the grouting of the installation hole. Therefore, in order to facilitate the grouting of the installation hole, the grouting pipe 6 is mechanically pressed to form a flat tube portion 62 with a length of 150 mm near its bottom, and the rest is a round tube portion 61. One end of the round tube portion 61 is fixedly connected to the lower end cover 5 and communicated with the inside of the grouting tube 1, and the other end is integrally formed with the flat tube portion 62. During grouting, the flat tube portion 62 is inserted into the installation hole on one side of the steel bar, and then grouting is performed, which is more convenient and has a better grouting effect.

[0040] Reference Figure 2 and Figure 3Furthermore, in order to increase the convenience during grouting and avoid the construction workers from working on the grouting tube 1 all the time, which is quite strenuous, the grouting equipment also includes a support frame 7, which is a trapezoidal frame, including a support frame 71, and the support frame 71 is a square frame with a length of 200 mm. The bottom of the support frame 71 is fixedly connected with four legs 72 at its four corners, and the legs 72 are inclined to extend in a direction away from the center of the support frame 71 to form a trapezoidal support frame 7 with the support frame 71. The height of the legs 72 is 510 mm, and the distance between the lower ends of two adjacent legs 72 is 300 mm. Two 30mm round tube supports 11 are fixedly provided on the outer wall of the grouting tube 1 at a position 280mm near the upper end cover; a supporting device 8 for positioning the grouting tube 1 is fixedly provided on the supporting leg 72 below the supporting frame 71. When grouting, the end of the grouting tube 1 with the grouting pipe 6 is inserted into the supporting frame 7 from the supporting frame 71, and the two round tube supports 11 are placed on the supporting device 8 to position the grouting tube 1, and then the grouting work is carried out, so as to avoid the staff from holding the grouting tube 1 all the time, which is more labor-saving and convenient.

[0041] The supporting device 8 includes a supporting ring 81, and a cross brace 82 is fixedly provided between adjacent legs 72 at a position 80 mm from the bottom of the supporting frame 71. A fixing rod 83 is fixedly provided between the supporting ring 81 and the cross brace 82, and the fixing rod 83 fixes the supporting ring 81 on the cross brace 82. The grouting tube 1 is supported by placing the round tube support 11 on the upper part of the supporting ring 81.

[0042] Furthermore, after the slurry is poured into the grouting tube 1, it is necessary to take the grouting tube 1 out of the support frame 7 and then add slurry. Then, due to the existence of the support ring 81, the grouting tube 1 needs to be vertically moved up to the grouting pipe 6 to separate from the support ring 81 before the grouting tube 1 can be conveniently taken out of the support frame 7, which brings inconvenience to the construction personnel. Therefore, the support ring 81 is divided into two semicircular annular units 811, and the two annular units 811 are fixedly connected to the cross brace 82 by fixing rods 83 respectively. Three fixing rods 83 are arranged on each annular unit 811, and the fixing rods 83 are respectively arranged at both ends and in the middle of the annular unit 811. At the same time, a channel 812 is formed between the two annular units 811. When taking out the grouting tube 1, the grouting tube 1 can be tilted and moved upward, so that the grouting pipe 6 can move out of the support ring 81 using the channel 812, thereby reducing the moving height of the grouting tube 1 and increasing the convenience of operation.

[0043] Reference Figure 4 Since the grouting tube 1 of the present invention can stir the slurry in the grouting tube 1 after the slurry is used, in order to ensure the stability of the support frame 7 and the grouting tube 1 when the slurry is stirred, pedals 721 are fixedly provided at the bottom of the four legs 72 respectively. When stirring the slurry, both feet step on the pedals 721 to ensure the stability of the support frame 7.

[0044] The construction process is as follows:

[0045] Mixing the slurry in the grouting tube 1: first, invert the end of the grouting tube 1 close to the upper end cover 2 and insert it into the support frame 7, place the round tube support 11 on the support ring 81, and remove the lower end cover 5, pour the grouting raw materials and water into the grouting tube 1, step on the pedal 721 with both feet, and use the mixing equipment to mix the slurry in the grouting tube 1. After mixing evenly, install the lower end cover 5, remove the grouting tube 1 from the support frame 7 and reinsert the grouting tube 6 into the support frame 7 downward, and place the round tube support 11 on the support ring 81.

[0046] Grouting: insert the flat tube 62 into the installation hole and keep it 1-2 cm away from the bottom of the hole. Use the handle 41 to control the piston 3 to move downward, and grout the slurry in the grouting tube 1 from the bottom of the installation hole upward. After the grouting is completed, move the grouting tube 1 upward, move the grouting pipe 6 out of the installation hole, and move the support frame 7 together with the grouting tube 1 to the next installation hole to be grouted for grouting. After the slurry in the grouting tube 1 is used up, repeat the above steps to stir the slurry and grout.

[0047] The embodiments of this specific implementation method are all preferred embodiments of the present invention, and are not intended to limit the protection scope of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
