Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to a device for effectively controlling the quality of post-grouting of masonry exterior walls. Background Technology

[0002] In building construction, most structures utilize a frame-shear wall system. To save material waste and structural weight, and to enhance the thermal insulation performance of the exterior walls, lightweight, thermally insulated masonry blocks are used between the frames, and this is extensively applied to infill wall masonry. When constructing exterior masonry, to prevent uneven settlement, a 30-50mm gap (post-sealing) must be left between the infill wall and the load-bearing main structure. After 14 days, this gap is filled and reinforced with anti-corrosion wooden wedges and C20 fine aggregate concrete. Current technology only allows construction from the outside using a suspended platform (due to the small gap at the top, effective post-sealing cannot be performed directly from inside), sealing the gap from the outside. This not only increases costs and construction difficulty but also compromises quality and safety. Therefore, this solution provides a device for effectively controlling the quality of post-sealing in exterior masonry, enabling the post-sealing work to be carried out indoors instead of outdoors. Utility Model Content

[0003] The purpose of this invention is to provide a device that is simple to operate and can effectively control the quality of caulking after masonry work is carried out indoors.

[0004] This utility model is achieved through the following measures:

[0005] A device for effectively controlling the quality of post-sealing of masonry joints in exterior walls, characterized in that it includes a side plate, a through transverse groove is provided on the side plate, an operating rod is provided through the groove, the operating rod is provided with external threads on its periphery, a fixing nut is provided at one end of the operating rod, and a pre-tightening plate and a locking nut are sequentially and movably provided on the periphery of the other end of the operating rod after passing through the groove.

[0006] The specific features of this utility model also include:

[0007] The side panel includes an upper side panel and a lower side panel, which are hinged together by a hinge. The hinge is located on the inner surface of the upper and lower side panels facing the pre-tightening plate. A sliding groove is provided on the upper side panel. After the lower side panel is rotated outward to its maximum limit angle, it is flush with the upper side panel. In use, the lower side panel is first rotated inward and folded to ensure that it can pass through the back sealing gap. After passing through the back sealing gap, the operating rod is tightened so that the upper side panel abuts against the outer wall surface above the back sealing gap, and the lower side panel abuts against the outer wall surface below the back sealing gap. Then, the locking nut is rotated so that the pre-tightening plate is pressed against the interior wall. Then, concrete is filled into the back sealing gap from the interior. Specifically, concrete can be stuffed in with a small trowel. After completing one section, the device is moved to the next section. In addition, a film is placed on the inside of the side panel. After the device is moved, the film effectively insulates and moisturizes the outer concrete.

[0008] A circular washer is provided around the operating rod between the fixing nut and the side plate.

[0009] The locking nut is provided with an annular plate, and the annular plate is provided with a spring. The other end of the spring is provided on the pre-tightening plate. Both the annular plate and the spring are provided around the operating rod. The spring is a high-strength spring. Through the action of the spring and the pre-tightening plate, the side plate can be better pulled and fastened to the wall.

[0010] Slide groove 2 is provided on both the upper and lower sides of slide groove 1. A sliding block is slidably arranged between slide groove 2 on both sides. An auxiliary rod parallel to the operating rod is provided on the sliding block. Slide groove 3 is provided on the pre-tightening plate. Both the operating rod and the auxiliary rod pass through slide groove 3. After the operating rod passes through slide groove 3, a locking nut is provided on its outer periphery. After the side plate is passed through and the gap is sealed, the side plate is horizontally aligned by the separation of the auxiliary rod and the operating rod, thus avoiding the problem of using other tools to horizontally align the side plate.

[0011] The auxiliary rod has a groove near its free end, and a rod is rotatably inserted into the groove. Correspondingly, the operating rod has a slot that engages with the rod. By separating the auxiliary rod and the operating rod to the sides, the side plate is horizontally aligned. Then, the locking nut presses the pre-tensioning plate against the interior wall, thereby pressing the side plate against the exterior wall. To avoid interfering with construction, the auxiliary rod is slid towards the operating rod, and the rod is inserted into the slot, fixing the auxiliary rod and the operating rod together.

[0012] The outer side of the operating rod is provided with a bolt that passes through the slot via a threaded structure, and the corresponding end face of the insertion rod is provided with a threaded hole that mates with the bolt. When the insertion rod is inserted into the slot, the auxiliary rod and the operating rod are fixedly connected by the bolt.

[0013] A concave groove is provided on the free end face of the insertion rod, and a threaded hole is provided on the bottom surface of the concave groove. The concave groove allows the insertion rod to be easily rotated out of the groove with a finger and then inserted into the slot.

[0014] The beneficial effects of this utility model are as follows:

[0015] Existing technologies only allow for construction by erecting a suspended platform on the outside, sealing from the outside. This not only increases costs and construction difficulty but also compromises quality and safety. This patent improves the work method by shifting construction from outdoors to indoors, improving construction quality and significantly reducing safety hazards associated with outdoor work. This patent can be used for filling all joints in exterior wall masonry, and the device is reusable, energy-efficient, and environmentally friendly. Attached Figure Description
