Description

Technical Field

[0001] This utility model belongs to the technical field of mortar application tools, specifically relating to a special mortar construction device for precast panel walls. Background Technology

[0002] In the field of prefabricated buildings, precast panel walls, as a lightweight and environmentally friendly wall material, are widely used due to their convenient construction and high degree of industrialization. During the installation of panel walls, bonding mortar needs to be applied to the joints of the panels or at the connection points with the main structure to ensure the integrity and seismic performance of the wall. Traditional mortar application processes rely heavily on manual labor, with workers using hand-held trowels or scrapers to spread the mortar, which presents the following technical challenges:

[0003] 1. Efficiency and uniformity issues: Manual application relies on workers' experience, and the mortar thickness is difficult to control precisely, which can easily lead to uneven thickness or local leakage, affecting the bonding strength between the panels and increasing the risk of wall cracking.

[0004] 2. Material waste and construction costs: Manual application makes it difficult to accurately distribute the amount of mortar, and excess mortar is prone to overflowing into the joint area, resulting in material waste and requiring additional cleaning procedures, which prolongs the construction period.

[0005] 3. High labor intensity: Repetitive painting actions can easily lead to worker fatigue, especially in high-rise or large-space construction, where efficiency bottlenecks are significant and it is difficult to meet the standardized requirements of industrialized construction. Utility Model Content

[0011] Furthermore, the rolling support is a roller, and there are two parallel rollers inside the trough of the mortar hopper.

[0012] Furthermore, a mortar collection bin is installed on the mortar hopper below the mortar outlet. The mortar collection bin has a trowel plate that is flush with the mortar outlet, and the inlet of the mortar collection bin is located above the trowel plate.

[0013] Furthermore, the mortar collection bin can be slidably fastened to the downward-sloping top plate of the mortar hopper, and the two connecting ears on the mortar collection bin can be slidably attached to the outside of the side plate of the mortar hopper. The connecting ears have a second elongated hole parallel to the downward-sloping top plate of the mortar hopper. A second screw is provided on the side plate of the mortar hopper. The second screw is located in the second elongated hole of the connecting ear, and a second nut is connected to the second screw. The second nut is used to lock the connecting ears.

Detailed Implementation

[0022] 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.

[0023] like Figure 1 , Figure 3 The diagram shows a mortar construction device for precast panel walls, comprising a mortar hopper 1 with an open trough 1.1. A rolling support 2 is installed inside the trough 1.1. The mortar hopper 1 is movably engaged with the panel wall via the trough 1.1, and the rolling support 2 provides rolling support on the vertical surface of the panel wall. The two side walls of the trough 1.1 slide in contact with the two side surfaces of the panel wall. A mortar holding space is formed between the mortar hopper 1 and the panel wall. The mortar holding space is wedge-shaped, wider at the top and narrower at the bottom. The top opening of the mortar holding space serves as the mortar inlet, and the bottom opening serves as the mortar outlet. Mortar is poured into the mortar holding space through the mortar inlet, and as the mortar hopper 1 is pushed upwards, the mortar flows out from the mortar outlet, adhering to the vertical surface of the panel wall.

[0024] like Figure 1 , Figure 2 , Figure 4 As shown: An adjustable scraper 5 is installed at the mortar outlet of the mortar hopper 1. The height of the mortar outlet can be changed by the scraper 5 to adjust the thickness of the mortar coating.

[0025] A first screw 8 is provided on the downwardly inclined top plate of the mortar hopper 1. A first elongated hole 5.1 is opened on the scraper 5. The scraper 5 is fitted onto the first screw 8 through the first elongated hole 5.1. The scraper 5 can move within the range of the first elongated hole 5.1. A first nut 9 is connected to the first screw 8. The first nut 9 is used to lock the scraper 5. When the first nut 9 is loosened, the scraper 5 can slide. When the first nut 9 is locked, the position of the scraper 5 is fixed.

[0026] A support rod 4 is connected to the mortar hopper 1, and the support rod 4 is hinged to the mortar hopper 1; the support rod 4 extends the working height of the mortar hopper 1.

[0027] The rolling support part 2 is a roller, and there are two parallel rollers in the trough 1.1 of the mortar hopper 1.

[0028] A mortar collection chamber 7 is installed on the mortar hopper 1 below the mortar outlet. The mortar collection chamber 7 has a trowel 7.1 flush with the mortar outlet. The trowel 7.1 is used to smooth the mortar flowing out of the mortar outlet of the mortar hopper 1. The inlet of the mortar collection chamber 7 is located above the trowel 7.1. Excess mortar flows into the mortar collection chamber 7.

[0029] The position of the trowel plate 7.1 on the mortar collection bin 7 can be adjusted with the scraper 5. The mortar collection bin 7 can slide and be fastened to the downward-sloping top plate of the mortar hopper 1. The two connecting ears 7.2 on the mortar collection bin 7 can slide and be attached to the outside of the side plate of the mortar hopper 1. The connecting ears 7.2 have a second elongated hole 7.3 parallel to the downward-sloping top plate of the mortar hopper 1. A second screw 10 is provided on the side plate of the mortar hopper 1. The second screw 10 is located in the second elongated hole 7.3 of the connecting ear 7.2. A second nut 11 is connected to the second screw 10, and the second nut 11 locks the connecting ear 7.2. When the mortar collection bin 7 slides along the downward-sloping top plate of the mortar hopper 1, the height of the trowel plate 7.1 to the vertical surface of the strip wall is adjusted. The mortar collection bin 7 can move within the range of the second elongated hole 7.3. When the second nut 11 is loosened, the mortar collection bin 7 can move. When the second nut 11 is tightened, the position of the mortar collection bin 7 is fixed.
