Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to a slurry-spraying tool for building wall construction. Background Technology

[0002] In building wall construction, the slurry application process is an important step before plastering. It involves applying a layer of concrete slurry to the wall to enhance the adhesion of the substrate and prevent hollow spots and peeling. Traditional slurry application methods mainly rely on manual operation using brushes, rollers, or simple slurry boards. Because simple slurry boards are more convenient to use than the other two tools, they are widely used in practice. However, simple slurry boards still have the following drawbacks:

[0003] Existing simple slurry slabs and supporting frames are usually rigidly connected. When the slurry slab hits the wall, the impact force is directly transmitted to the operator's hand through the rigid structure (such as the handle and support rod). Long-term operation can easily lead to hand fatigue and even joint damage. Workers need to rely on their arm muscles to actively absorb the force, which increases the workload, especially during continuous construction. In addition, the angle of the slurry slab is not easy to adjust. When slurrying is required on the walls at the top of some buildings, the existing structure in which the slurry slab and support rod are set parallel to each other is inconvenient to operate.

[0004] Therefore, there is an urgent need for a slurry application tool for building wall construction. By optimizing the connection structure, the slurry application board can be made to have the ability to rebound during construction. This can reduce the adverse effects on the operator and allow for flexible adjustment of the position of the slurry application board and the support rod according to the operational needs, thereby improving the convenience of slurry application and ensuring the slurry application effect. Utility Model Content

[0005] The purpose of this utility model is to provide a slurry application tool for building wall construction. By optimizing the connection structure, the slurry application board has the ability to rebound during construction, which can reduce the adverse effects on the operator and flexibly adjust the position of the slurry application board and the support rod according to the operational needs, thereby improving the convenience of slurry application and ensuring the slurry application effect.

[0006] The present invention adopts the following technical solution:

[0007] A slurry application tool for building wall construction includes a slurry application plate with a plurality of slurry application holes through its surface. A protective frame is provided at one end of the slurry application plate away from the working surface. A sealing cover is elastically connected to the protective frame. A feeding port is provided on the sealing cover, and a sealing plate is provided at the feeding port. A support rod is provided at the bottom of the sealing cover, wherein the sealing cover can be rotated and adjusted relative to the support rod.

[0008] Preferably, the sealing cap and the protective frame are connected by a spring.

[0009] Preferably, the protective frame is provided with a guide rod, the sealing cover is provided with a guide hole for the guide rod to pass through, and the spring is sleeved on the outside of the guide rod.

[0010] Preferably, the guide rod is provided with an external thread, and an adjusting nut is provided after the guide rod passes through the guide hole.

[0011] Preferably, baffles are provided on the sealing caps on both sides of the feeding port, and the ends of the two baffles away from the sealing caps extend toward the center of the sealing caps to form a support structure. The sides of the baffles are right-angled triangles, and the right-angled sides are connected to the sealing caps. The sealing plate is hinged between the two baffles.

[0012] Preferably, a pressure plate is hinged to the sealing cover, and the sealing plate has a groove for the pressure plate to press the cover.

[0013] Preferably, the sealing cover is provided with a hinge plate, the support rod is provided with a hinge seat, and the hinge seat is rotatably disposed between the two hinge plates via a hinge shaft; a positioning cap is elastically provided on the outside of one of the hinge plates, a positioning rod is provided inside the positioning cap, and a positioning hole is provided on the hinge shaft for the positioning rod to pass through.

[0014] Preferably, the positioning rod is square or cross-shaped, and the positioning hole structure matches the positioning rod.

[0015] Preferably, the hinge plate is provided with a positioning toothed disc, which is coaxially sleeved outside the hinge shaft; the end face of the positioning cap is provided with a positioning tooth groove, which meshes with the positioning toothed disc.

[0016] Preferably, the protective frame is provided with multiple interwoven reinforcing ribs.

[0017] Compared with existing technologies, the advantages of this utility model are as follows: By elastically setting the slurry-spraying plate and the sealing cap, this utility model can absorb part of the impact force when the slurry-spraying plate hits the wall, avoiding the instantaneous recoil on the hand caused by rigid rebound. The elastic setting makes the tool easier to control, especially on uneven walls, reducing the risk of accidental slippage or deviation. In addition, the elastic setting of the slurry-spraying plate can also enhance the kinetic energy of the slurry when it is thrown out, improving the slurry-spraying effect and enhancing the adhesion of the slurry to the wall. The rotatable adjustment of the sealing cap and the support rod allows the slurry-spraying plate and the support rod to be adjusted to a vertical state when slurry is needed on the wall at the top of the building, so that the slurry-spraying plate can better contact the top wall and complete the slurry-spraying operation, improving the convenience of operation.

[0022] The present invention will now be described clearly and completely with reference to the accompanying drawings and embodiments:

[0023] like Figures 1 to 4 The present invention discloses a slurry application tool for building wall construction, comprising a slurry application plate 1 with a plurality of slurry application holes through its surface. A protective frame 2 is provided at the end of the slurry application plate 1 away from the working surface. The protective frame 2 is preferably integrally formed with the slurry application plate 1. Furthermore, multiple interwoven reinforcing ribs 3 are provided between the protective frames 2 to ensure its structural strength. A sealing cap 4 is elastically connected to the protective frame 2. The sealing cap 4 is a frame structure with one open end. The protective frame 2 is fitted over the sealing cap 4, and the protective frame 2 and the side walls of the sealing cap 4 partially overlap and slide in contact to prevent… The slurry overflows; the sealing cap 4 is equipped with a feeding port for adding slurry, and a sealing plate 5 is installed at the feeding port. During operation, the sealing plate 5 is in a closed state to prevent slurry from falling during the slurry throwing process; a support rod 6 is provided at the bottom of the sealing cap 4, and the sealing cap 4 can be rotated and adjusted relative to the support rod 6. So that when slurry throwing is required on the top wall of some buildings, by adjusting the sealing cap 4 to be in a perpendicular state to the support rod 6, the support rod 6 can be moved up and down to make the slurry throwing plate 1 contact the wall at the top of the building, thereby completing the slurry throwing operation and improving the convenience of slurry throwing. This utility model, through the elastic setting of the slurry throwing plate 1 and the sealing cap 4, can absorb part of the impact force when the slurry throwing plate 1 hits the wall, avoiding the instantaneous recoil of the hand from rigid rebound. The elastic setting makes the tool easier to control, especially on uneven walls, reducing the chance of the tool accidentally slipping out of hand or deviating. In addition, the elastic setting of the slurry throwing plate 1 can also enhance the kinetic energy of the slurry when it is thrown out by elastic potential energy, improving the slurry throwing effect and enhancing the adhesion of the slurry to the wall.

[0024] Specifically, the sealing cover 4 and the protective frame 2 are connected by springs 7. Multiple springs 7 can be installed, arranged at the top, bottom, left, and right positions of both the sealing cover 4 and the protective frame 2 to achieve a stable connection. Both the protective frame 2 and the sealing cover 4 are equipped with mounting plates. A guide rod 8 is installed on the mounting plate of the protective frame 2, and a guide hole is provided on the mounting plate of the sealing cover 4 for the guide rod 8 to pass through. The spring 7 is sleeved on the outside of the guide rod 8, with both ends connected to the mounting plate. The guide rod 8 provides guidance for the movement of the protective frame 2. Furthermore, the guide rod 8 has external threads, and an adjusting nut 9 is installed after the guide rod 8 passes through the guide hole. Rotating the adjusting nut 9 compresses the spring 7, thereby adjusting the spring force of the spring 7 to meet different operational needs.

[0025] Furthermore, in this embodiment, baffles 10 are provided on the sealing caps 4 on both sides of the feeding port. The ends of the two baffles 10 away from the sealing cap 4 extend towards the middle of the sealing cap 4 to form a support structure. The sides of the baffles 10 are right-angled triangular structures, and the right-angled sides are connected to the sealing cap 4. The bottom of the sealing plate 5 is hinged between the two baffles 10. When feeding is required, the sealing plate 5 is opened so that it abuts against the support structure formed between the sealing plate 5 and the baffles 10. At this time, a guide hopper structure can be formed between the sealing plate 5 and the baffles 10, which facilitates the smooth addition of slurry into the protective frame 2. In addition, a pressure plate 11 is hinged on the sealing cap 4. The pressure plate 11 can be rotated and adjusted along the hinge point. The sealing plate 5 is provided with a groove for the pressure plate 11 to press the cap. In the working state, the pressure plate 11 is pressed into the groove, which can limit the sealing plate 5 and prevent the slurry from falling out when the sealing plate 5 is opened during operation.

[0026] Furthermore, a hinge plate 12 is provided on the sealing cover 4, and a hinge seat 13 is provided on the support rod 6. The hinge seat 13 is rotatably disposed between the two hinge plates 12 via a hinge shaft 14, that is, the hinge shaft 14 is fixedly disposed on the hinge seat 13, and the hinge shaft 14 is rotatably connected to the hinge plate 12. A positioning cap 16 is elastically disposed on the outside of one of the hinge plates 12 via a positioning spring 15, and a positioning rod 17 is disposed inside the positioning cap 16. A positioning hole for the positioning rod 17 to pass through is provided on the hinge shaft 14. Since the slurry plate 1 usually only needs to be adjusted to be parallel or perpendicular to the support rod 6, the positioning rod 17 is preferably set as a square or cross-shaped symmetrical structure, and the positioning hole structure matches the positioning rod 17. This ensures that after the hinge shaft 14 rotates 90 degrees relative to the hinge plate 12, the positioning rod 17 can be smoothly inserted into the positioning hole to complete the positioning. During the slurry ejection process, the vibration of the slurry ejection plate 1 will cause the hinge shaft 14 to shake, generating a certain torque on the positioning spring 15. Therefore, in this example, a positioning toothed disc 18 is provided on the hinge plate 12, and the positioning toothed disc 18 is coaxially sleeved on the outside of the hinge shaft. A positioning toothed groove is provided on the end face of the positioning cap 16, and the positioning toothed groove meshes with the teeth on the positioning toothed disc 18, which further ensures the stability between the slurry ejection plate 1 and the support rod 6 after adjustment, thereby reducing the adverse effects on the positioning spring 15 during operation and ensuring its service life.

[0027] In use, this invention first opens the sealing plate 5, adds slurry through the feeding port, and then uses the pressure plate 11 to limit the sealing plate 5 before slurry application. Because the slurry application plate 1 and the sealing cap 4 are elastically designed, they absorb some of the impact force when the slurry application plate 1 hits the wall, preventing a rigid rebound that could cause instantaneous impact on the hand. Simultaneously, the elasticity of the slurry application plate 1 makes the tool easier to control, especially on uneven walls, reducing the risk of accidental slippage or deviation. When slurry application is needed on the top of the building wall, pull the positioning cap 16, rotate the support rod 6 to make it perpendicular to the slurry application plate 1, and finally release the positioning cap 16. Under the elastic restoring force of the positioning spring 15, the hinge shaft 14 is repositioned. The structure is simple, the operation is convenient, and it is highly practical.
