Description

Technical Field

[0001] The utility model relates to the field of assembled buildings, in particular to an assembled building joint device. Background Art

[0002] Prefabricated construction refers to transferring a large amount of on-site work in traditional construction methods to factories. Prefabricated wall panels for construction are processed and manufactured in factories, and then transported to the construction site for assembly. During assembly, there will be many joints between prefabricated wall panels that need to be sealed.

[0003] The existing sealing method is usually to manually use tools to perform plastering and sealing, and then grouting and sealing the inside of the joint after waiting for the plastering sealing material to dry. This sealing method is very slow and cumbersome, and cracks will appear when the plastering is unevenly applied during sealing, and the grouting material will leak when the internal grouting is sealed. When the leakage is severe, the prefabricated wall panels need to be hoisted and reassembled, which increases labor intensity and prolongs the construction progress. Utility Model Content

[0004] In order to solve the above-mentioned problems, the utility model provides an assembled building joint device.

[0005] The utility model is realized through the following technical solutions:

[0006] An assembled building joint device comprises a plurality of prefabricated wall panels spliced ​​together, baffles are arranged on the outer sides of adjacent prefabricated wall panels, joints are formed between the adjacent prefabricated wall panels and the baffles, a blocking plate for blocking the joint is arranged on the outer sides of the prefabricated wall panels, and a plurality of fastening components are arranged on the back of the blocking plate to prevent the blocking plate from falling off.

[0007] Further optionally, the fastening assembly includes two connecting brackets fixed on the back of the sealing plate, a trapezoidal slider is arranged between the connecting brackets, the trapezoidal slider extends to the outside of the sealing plate and is slidably connected thereto, and the trapezoidal slider on the inside of the sealing plate is slidably connected to push rods on the left and right sides respectively, and the push rods extend to the outside of the connecting brackets and are connected and fixed to the supporting top plate.

[0008] Further optionally, a spring is connected and fixed between the corresponding connecting bracket and the supporting top plate.

[0009] Further optionally, a plurality of anti-slip cones are provided on the outer side of the corresponding support top plate.

[0010] Further optionally, sliding grooves for slidingly cooperating with the push rod are provided on both sides of the trapezoidal sliding block.

[0011] Further optionally, sealing gaskets are provided on both sides of the blocking plate.

[0012] Further optionally, a pin shaft is slidably connected to the inner side of the blocking plate and is used in conjunction with the insertion hole on the trapezoidal sliding block.

[0013] Compared with the existing technology, the beneficial effect of the utility model is that the utility model fundamentally solves a series of problems caused by loose sealing of joints by arranging sealing plates and fastening components on the outside of prefabricated wall panels, greatly improves work efficiency, reduces the labor intensity of construction workers, and better ensures the sealing effect of joints.

[0019] The present invention is further described in detail below in conjunction with the accompanying drawings and specific implementations:

[0020] like Figure 1 , 2 As shown, an assembled building joint device includes a plurality of prefabricated wall panels 1 spliced ​​together, baffles 14 are arranged on the outer sides of adjacent prefabricated wall panels 1, joints 4 are formed between the adjacent prefabricated wall panels 1 and the baffles 14, and blocking plates 2 for blocking the joints 4 are arranged on the outer sides of the prefabricated wall panels 1, and a plurality of fastening components are arranged on the back of the blocking plates 2 to prevent them from falling off.

[0021] like Figure 1 , 3 As shown in , 4, the fastening assembly includes two connecting brackets 11 fixed on the back of the sealing plate 2, a trapezoidal slider 3 is arranged between the connecting brackets 11, the trapezoidal slider 3 extends to the outside of the sealing plate 2 and is slidably connected thereto, and the left and right sides of the trapezoidal slider 3 on the inner side of the sealing plate 2 are respectively slidably connected to push rods 5, and the push rods 5 extend to the outside of the connecting brackets 11 and are connected and fixed to a supporting top plate 7.

[0022] like Figure 2 , 3As shown in , 4 , a spring 6 is connected and fixed between the corresponding connecting bracket 11 and the supporting top plate 7 .

[0023] like Figure 2 , 3 As shown in FIG. 4 , a plurality of anti-slip cones 8 are arranged on the outer side of the corresponding supporting top plate 7 .

[0024] like Figure 3 As shown, two sides of the trapezoidal sliding block 3 are provided with sliding grooves 10 which are slidably matched with the push rod 5 .

[0025] like Figure 2 , 3 As shown, sealing pads 9 are arranged on both sides of the blocking plate 2 .

[0026] like Figure 2 , 4 As shown, a pin shaft 12 is slidably connected to the inner side of the blocking plate 2 and is used in conjunction with an insertion hole 13 on the trapezoidal slider 3 .

[0027] The implementation principle of an assembled building joint device in the embodiment of the present application is:

[0028] Before plugging, first press the plugging plate 2 onto the prefabricated wall panel, make the sealing gasket fit tightly with the prefabricated wall panel 1, and place several fastening components in the joint 4, and then prepare for plugging;

[0029] When sealing, it is necessary to push the trapezoidal slider 3 into the joint 4. While pushing the slider 3, the push rod 5 will be pushed out horizontally, so that the supporting top plate 7 is closely fitted with the side wall of the prefabricated wall panel 1, and the anti-slip cone 8 will be nailed into the side wall of the prefabricated wall panel 1 to prevent slipping. At the same time, the pin shaft 14 on the back of the blocking plate 2 will slide on the upper surface of the trapezoidal slider 3. When the trapezoidal slider 3 is pushed to be in the same plane as the blocking plate 2, the pin shaft 12 on the back of the blocking plate 2 will automatically fall directly into the insertion hole 13 to prevent the trapezoidal slider 3 from being pushed out by the pressure of the mortar during grouting and sealing. At the end of the trapezoidal slider 3, the blocking plate 2 will be completely sealed to prevent leakage, thereby completing the joint work. The whole process saves time and effort, greatly improves work efficiency, and completely avoids leakage due to loose joints, thereby better reducing the labor intensity of construction personnel.
