Description

Technical Field

[0001] The utility model relates to the field of building construction, in particular to a pipe sleeve mould for reserved openings in kitchens and bathrooms. Background Art

[0002] During the pouring construction of the floor slab, the floor slab in the area where the kitchen and bathroom are located is reserved for pipe openings. In the prior art, the Chinese utility model patent with application number 202120932616.8 discloses a detachable mold for reserved openings on the floor slab of a construction project. The mold has the characteristics of strong practicality, good formability, and high turnover rate. However, a stopper is fixed at the lower end of the pull screw in the mold, and the stopper is against the bottom surface of the floor slab formwork, resulting in the need to insert the pull screw separately from the bottom surface of the floor slab formwork when disassembling the entire mold, and the remaining parts are installed from the top surface of the floor slab formwork, resulting in the entire disassembly and assembly process being not very quick and convenient.

[0017] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0018] like Figures 1 to 3 As shown, the present embodiment discloses a pipe sleeve mold for reserved holes in kitchens and bathrooms, including a mold tube 1 with opening structures at both ends, a tie rod 2 is arranged in the mold tube 1, a slot 201 is opened at the lower end of the tie rod 2, a pair of symmetrically arranged anti-slip rods 3 are arranged in the slot 201, the anti-slip rods 3 are in a "7" shape, and the anti-slip rods 3 are rotatably connected in the slot 201 through an axial rod, and a locking sleeve 4 that can move up and down is provided on the outer side of the tie rod 2, and the locking sleeve 4 is pressed and fitted with the anti-slip rod 3.

[0019] A connecting plate 5 is fixed to the upper end of the mold cylinder 1, and a mounting hole 501 is opened in the middle of the connecting plate 5. The mounting hole 501 is plugged into the tie rod 2. A locking nut 6 is arranged above the mounting hole 501, and the locking nut 6 is threadedly connected to the tie rod 2.

[0020] In this embodiment, a rubber sleeve 7 is sleeved on the outer side of the mold tube 1. After the concrete floor is poured and hardened, the mold tube 1 is rotated to be taken out, and then the rubber sleeve 7 is taken out. The advantage of this design is that it is easy to take out the mold tube 1, and it prevents the corners of the hole from being damaged due to forced extraction of the mold tube 1. At the same time, in order to further facilitate the separation of the mold tube 1 and the rubber sleeve 7, grease can be applied on the outer wall of the mold tube 1.

[0021] In this embodiment, the locking nut 6 is a butterfly nut.

[0022] In this embodiment, the locking sleeve 4 is threadedly connected to the tie rod 2 .

[0023] In this embodiment, a handle 8 is fixed on the top of the connecting plate 5.

[0024] In this embodiment, the mold cylinder 1, the tie rod 2, the anti-drop rod 3, the locking sleeve 4, the connecting plate 5, and the handle 8 are all made of stainless steel.

[0025] like Figure 4 As shown, the use process of the utility model is as follows:

[0026] Before pouring the concrete floor slab, the positions where the holes are to be reserved are marked on the floor slab formwork 9, and formwork holes 901 are drilled at the positioning marks of the formwork.

[0027] Retract the lower end of the anti-slip rod 3 into the slot 201, and insert it into the template hole 901 together with the tension rod 2, then retract the upper end of the anti-slip rod 3 into the slot 201, and turn the locking sleeve 4 downward until the locking sleeve 4 completely covers the anti-slip rod 3. At this time, the two anti-slip rods 3 are arranged in an eight-shape to prevent the tension rod 2 from escaping from the template hole 901, and then the mold cylinder 1 is sleeved on the tension rod 2, and the upper end of the tension rod 2 passes through the mounting hole 501 and is threadedly connected with the locking nut 6. Fix the upper end of the tension rod 2 with one hand, and rotate the locking nut 6 with the other hand to make it rest against the connecting plate 5, thereby achieving the fixation of the mold cylinder 1.

[0028] After the concrete slab is poured and hardened, the mold tube 1 can be rotated out by loosening and removing the locking nut 6, and then the locking sleeve 4 is rotated upward to disengage it from the anti-slip rod 3, and the tension rod 2 can be directly pulled out from the template hole 901.

[0029] The embodiments described above are only descriptions of the preferred methods of the present invention, and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary technicians in this field should fall within the protection scope determined by the claims of the present invention.
