Description

Technical Field

[0001] This invention relates to the field of building engineering technology, specifically to a tool for grouting infill walls in building structures. Background Technology

[0002] In building construction, the construction of infill walls is a sub-project of the main structure acceptance process and also belongs to the concealed works before plastering. Its quality is an important step in the acceptance of the main structure. Specifications require that the mortar joint thickness of infill walls be 8-12mm, and the joints must be horizontal and vertical, uniform in thickness, and free from transparent, blind, or false joints. Current construction methods involve spraying a concrete curing agent (or water) onto the mortar surface within the joints and then grouting with a grouting tool. However, existing grouting tools can only compact the existing mortar coated with the concrete curing agent within the joints. The mortar coated with the concrete curing agent is easily squeezed out by the grouting tool, resulting in insufficient density and easily leading to the aforementioned transparent, blind, and false joints. Utility Model Content

[0003] This invention discloses a tool for grouting infill walls of building structures, with the aim of solving the problems described in the background section.

[0023] The technical solutions of this invention will now be clearly and completely described with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0024] The following embodiments can be understood as explaining a partial structure of the present invention individually, or as explaining a larger structure of the present invention through a combination of multiple embodiments.

[0025] In the initial embodiment, this novel building structure infill wall masonry grouting tool, such as... Figure 1-5 As shown, the system includes a base plate 3. A pressure rod 5 is welded to the central axis along the front-to-back direction on the lower surface of the base plate 3. A filler extrusion mechanism is welded to the base plate 3 at the front end and / or rear end of the pressure rod 5. The filler extrusion mechanism works in conjunction with the pressure rod 5 to press the filler into the gaps of the masonry while grouting, thus avoiding quality problems caused by insufficient or loose filler. A longitudinally arranged support rod 2 is welded to the center of the upper surface of the base plate 3. A handle 1 is welded to the top of the support rod 2. When the worker uses it, he holds the handle. Because the support rod is located in the center, it is easier to ensure that the pressure rod is applied evenly.

[0026] In a further embodiment, such as Figure 5 As shown, a triangular notch 31 is provided in the middle of the front end and / or rear end of the base plate 3, and a filler extrusion mechanism is welded at the notch 31, such as... Figure 1-4 As shown, if notches are provided at both the front and rear ends of the base plate, this new type of plate can move forward to press the seam or move backward to press the seam.

[0027] In a further embodiment, such as Figure 1-4 As shown, the joint pressing rod 5 is a metal rod with a semi-circular cross-section and a diameter of 10-12mm (matching the conventional mortar joint width). The top surface of the joint pressing rod is horizontal, and the top surface of the joint pressing rod 5 is welded to the lower end of the base plate 3.

[0028] In a further embodiment, such as Figure 1 , 2 As shown, the front end and / or rear end of the pressing rod 5 are provided with a pressing surface 51 that is inclined forward or backward. During the pressing process, the pressing surface first contacts the filler in the mortar joint. During the movement, the filler is pressed into the mortar joint, and then the mortar joint is compacted and shaped by the rod body of the pressing rod.

[0029] In a further embodiment, such as Figure 1-4As shown, the packing extrusion mechanism is a shell structure with an open end and bottom, away from the handle 1. This shell structure can collect the packing that overflows from the mortar joint inside it. At the same time, during the movement, as the packing accumulates inside the shell, it is squeezed by the inner wall of the shell and re-enters the mortar joint, thereby applying pressure to the packing in the mortar joint and further promoting the compaction of the packing in the mortar joint.

[0030] In a further embodiment, such as Figure 1-4 As shown, the packing extrusion mechanism is a triangular pyramid shell structure 7. The end of the triangular pyramid shell structure 7 away from the handle 1 is an open end 71, which is used to collect the packing that overflows from the mortar joint. The two side wall edges of the triangular pyramid shell structure 7 are welded to the two sides of the notch 21 to form a packing collection space 72. The bottom surface of the triangular pyramid shell structure 7 is open to press the packing back into the mortar joint and promote the compaction of the packing in the mortar joint.

[0031] In a further embodiment, such as Figure 1-4 As shown, the open end 71 is inclined upwards or backwards. When the packing in the packing collection space 72 is full, the excess packing can cross the edge of the open end 71 that is inclined upwards or backwards and enter the excess packing recovery space 11 formed by the baffle 4, partition 6 and bottom plate 3.

[0032] In a further embodiment, such as Figure 1-4 As shown, baffles 4 are welded to the left and right ends of the upper surface of the base plate 3, and the two ends of the baffles 4 are aligned with or extend beyond the front and rear ends of the base plate 3; partitions 6 are respectively provided on the front and rear sides of the support rod 2 on the base plate 3, and the partitions 6, baffles 4, and base plate 3 together form an excess filler recovery space 11. Figure 3 As shown, excess filler on the wall surface is shoveled into the base plate or introduced into the excess filler recovery space 11 through the two side walls of the triangular pyramid shell structure 7.

[0033] In use, the handle is held to press the grouting rod into the mortar joint. The base plate contacts the wall surface and moves along the mortar joint. On one hand, the head of the grouting rod has a pressing surface 51, which can compact the filler into the mortar joint before pressing and shaping. On the other hand, the filler that overflows into the mortar joint is collected and compressed by the triangular pyramid shell structure and re-enters the mortar joint. The compression of the triangular pyramid shell structure further promotes the compaction of the filler in the mortar joint, ensuring the compaction effect. Any excess filler is either shoveled into the mortar joint through the base plate or guided into the excess filler recovery space 11 through the two side walls of the triangular pyramid shell structure 7. This design overcomes the problem of poor grouting quality caused by uneven and loose filler in the mortar joint in the prior art.

[0034] It should be noted that the filler involved in this invention refers to mortar coated with concrete curing agent (or water) and filled into the mortar joint. Compared with traditional grouting tools (such as round pipes), it has the effect of collecting the overflowing filler and further compacting the filler in the mortar joint.
