Description

[0002] At present, residential buildings generally adopt prefabricated structures, among which the most common prefabricated structural system is the sleeve grouting connection. In the wall grouting connection system, the gap between the prefabricated wall and the floor slab is generally sealed in advance with edge sealing materials, seat grouting materials or supporting formwork to avoid leakage due to large gaps during grouting, which makes it impossible to achieve effective connection of the wall reinforcement.

[0003] The use of the seat slurry method cannot guarantee the fullness of the seat slurry, and certain measures need to be taken to prevent the seat slurry from entering the grouting sleeve, which is prone to rework.

However, when using edge sealing materials for plugging, the construction thickness of the edge sealing materials needs to be controlled. If the edge sealing materials are too thick, the strength of the grouting materials around the steel bars will not meet the requirements.

[0021] like Figure 1 , Figure 2 As shown, the feed barrel 1 is cylindrical and used to contain the edge banding material. The discharge nozzle 2 is threadedly connected to the lower end of the feed barrel 1, and the lower end is a conical opening. The spiral blade 3 is rotatably connected to the feed barrel 1, and the drill bit of the electric drill 4 is plugged into the upper end of the spiral blade 3. The feed hopper 5 is connected to the upper end of the feed barrel 1, and the handle 6 is set on the outer wall of the upper end of the feed barrel 1.

[0022] When it is necessary to seal the gap between the prefabricated wall and the floor slab, the mixed edge sealing material is poured into the feed bucket 1 along the feed hopper 5, and lifted with one hand, and the electric drill 4 is held in the other hand, and then the drill bit of the electric drill 4 is inserted into the upper end of the spiral blade 3, and then the electric drill 4 is used to control the slow rotation of the spiral blade 3.

[0023] During the rotation of the spiral blade 3, the spiral blade 3 will cause the edge sealing material in the feed barrel 1 to be evenly squeezed out along the position of the discharge nozzle 2, and evenly seal the gap between the prefabricated wall and the floor slab, while effectively controlling the construction thickness of the edge sealing material to be consistent, meet the construction requirements, and ensure the construction quality.

[0024] like Figure 3 As shown, the discharge nozzle 2 includes a first connecting nozzle 21 and a first slurry discharge head 22, the first connecting nozzle 21 is threadedly connected to the lower end of the feed barrel 1, and the first slurry discharge head 22 includes a first vertical plate 23 and a pair of first side plates 24, the first vertical plate 23 is vertically arranged, and the pair of first side plates 24 are vertically arranged on both sides of the first vertical plate 23.

[0026] When the facades of the prefabricated wall and the floor are on the same horizontal plane, this type of discharge nozzle 2 is selected, and the first slurry discharge head 22 is embedded in the gap between the prefabricated wall and the floor. At the same time, the first baffle 231 protruding from the upper and lower ends contacts the facades of the prefabricated wall and the floor, so as to realize the limiting support of the discharge nozzle 2, so that the discharge nozzle 2 can move stably, ensure the uniform construction thickness of the edge sealing material, and avoid leakage of slurry on the outside caused by excessive gaps due to wall size deviations.

[0027] like Figure 4 As shown, the discharge nozzle 2 includes a second connecting nozzle 25 and a second slurry discharge head 26, the second connecting nozzle 25 is threadedly connected to the lower end of the feed barrel 1, and the second slurry discharge head 26 includes a second vertical plate 27 and a pair of second side plates 28, the second vertical plate 27 is vertically arranged, and the pair of second side plates 28 are vertically arranged on both sides of the second vertical plate 27.

[0028] like Figure 4 As shown, the upper half of one of the second side panels 28 is vertically arranged, and the lower half is bent outward and connected to the second connecting nozzle 25. At the same time, a second baffle 271 is vertically extended from the upper end of the second vertical panel 27, and the second baffle 271 is used to resist the outer facade of the prefabricated wall.

[0029] When the facades of the prefabricated wall and the floor are in a mutually perpendicular state, this type of discharge nozzle 2 is selected, and the second slurry discharge head 26 is embedded in the gap between the prefabricated wall and the floor. At the same time, the second baffle 271 protruding from the upper end contacts the facade of the prefabricated wall, and the lower end of the second slurry discharge head 26 extends outward to realize the limiting support of the discharge nozzle 2, so that the discharge nozzle 2 can move stably, ensuring the uniform construction thickness of the edge sealing material, and avoiding leakage of slurry on the outside due to excessive gaps caused by wall size deviations.

[0030] like Figure 2 , Figure 5 As shown, the upper and lower ends of the spiral blade 3 are rotatably connected to a sealing plate 31 that abuts against the inner wall of the feed barrel 1, the lower inner wall of the feed barrel 1 is provided with a clamping ring 11 that abuts against the sealing plate 31 below, the lower end surface of the sealing plate 31 below is provided with a clamping block 32, and the clamping ring 11 is provided with a clamping groove 12 for the clamping block 32 to be embedded.

The edge position of the sealing plate 31 located above is provided with a locking groove 33 for the locking rod 72 to be embedded.

[0033] like Figure 6 As shown, the pull rod 73 is horizontally arranged on the locking rod 72 and passes through the locking tube 71 . The spring 74 is sleeved on the outer wall of the pull rod 73 and is located between the locking rod 72 and the inner wall of the locking tube 71 .

[0034] When it is necessary to clean the inside of the edge sealer, pull the pull rod 73 to slide outward, and the pull rod 73 drives the locking rod 72 to slide synchronously until the locking rod 72 is embedded in the locking tube 71. The locking rod 72 is separated from the sealing plate 31 in the upper position, and then the spiral blade 3 and the pair of sealing plates 31 can be pulled outward to slide, so that the spiral blade 3 and the pair of sealing plates 31 can be removed.

[0040] When the edge sealing material needs to be prepared, the barrel cover 94 is removed, and the raw materials are placed in the batching barrel 9. The barrel cover 94 is then buckled on the feed barrel 1, and the handle 95 is assembled. The handle 95 is then used to drive the stirring paddle 92 to rotate to achieve stirring and mixing of the raw materials, thereby completing the on-site preparation of the edge sealing material.
