Description

Technical Field

[0001] This utility model relates to the field of building casting mold technology, and in particular to a one-time forming mold for supporting the floor of a residential exhaust duct. Background Technology

[0002] Concrete casting molds are temporary or permanent containers used to form concrete structures, and are widely used in civil engineering, building construction, bridge construction, water conservancy projects and other fields.

[0003] In current residential projects, the ventilation systems for kitchens and bathrooms are mostly prefabricated exhaust ducts installed in the second phase. For multi-story, high-rise, and even super high-rise buildings, the support of the prefabricated exhaust ducts at the floor level is particularly important. Traditional support methods mainly include L25×3 angle steel support and C12-14 threaded steel rebar support. Both of these support methods are relatively cumbersome and have problems such as difficulty in placing and anchoring angle steel in shear walls, and difficulty in controlling support spacing, flatness, and reliability.

[0004] Therefore, those skilled in the art are dedicated to developing a one-time forming mold for supporting the floor level of a residential exhaust duct, which facilitates the rapid forming of the floor level support and its installation in the designated location, saving construction time and improving project quality.

[0008] First mold body;

[0009] The second mold body is provided, and the first mold body and the second mold body are disposed opposite to each other. The first mold body and the second mold body are connected by a connecting component to form a mold body with a hollow cavity.

[0010] Steps are provided at the opposite positions of the sides of the first mold body and the second mold body, and the bottom plates of the first mold body and the second mold body each have multiple spaced connection holes.

[0011] The beneficial effects of adopting the above scheme are: the first mold body and the second mold body are connected by the connecting component to form a mold body with a hollow cavity, which is used to pour the support at the residential exhaust corridor floor, and the poured support has steps on both sides, which facilitates installation between the shear wall and the reinforced concrete floor slab; the connecting holes of the mold bottom plate are used to fix it with the support template to avoid the support template from being misaligned or floating.

[0012] Based on the above technical solution, the present invention can be further improved as follows.

[0013] Furthermore, the connecting assembly includes connecting plates disposed on the first mold body and the second mold body, the two connecting plates being disposed opposite each other and abutting each other, and the two connecting plates being connected by a bolt assembly.

[0014] The beneficial effect of adopting the above-mentioned further solution is that the connection plate and bolt assembly facilitate the quick connection and disassembly of the first mold body and the second mold body.

[0015] Furthermore, pull rings are connected to the upper side of both the first mold body and the upper side of the second mold body, and the pull rings are arc-shaped.

[0016] The beneficial effect of adopting the above-mentioned further solution is that the pull ring facilitates the movement and handling of the first mold body or the second mold body.

[0017] Furthermore, a cavity pre-reservation component is also installed on the second mold body.

[0018] The beneficial effect of adopting the above-mentioned further solution is that the cavity pre-reserved component is used for cavity forming during concrete pouring.

[0019] Furthermore, the cavity pre-reservation component includes a first through hole and a second through hole disposed opposite to each other in the second mold body.

One end of the cavity inner mold is connected to a blind plate and is connected to the side wall of the first through hole by a bolt assembly. A sealing element for sealing the cavity inner mold is provided on the outer periphery of the side wall of the second through hole.

[0020] The beneficial effect of adopting the above-mentioned further scheme is that the mold inside the cavity is used to form the cavity. After the concrete is formed, the slab and the second mold body are separated and removed, thereby forming the cavity.

[0021] Furthermore, concrete thickness adjustment components are also installed on the first mold body and the second mold body.

[0022] The beneficial effect of adopting the above-mentioned further solution is that the concrete thickness adjustment component is used to adjust the pouring thickness of the concrete, thereby adapting to the support at different locations.

[0023] Furthermore, the concrete thickness adjustment component includes a connecting screw and a vertical baffle. The connecting screw is disposed on the side wall of the first mold body or the second mold body.

[0037] First mold body 1;

[0038] The second mold body 2, the first mold body 1 and the second mold body 2 are arranged opposite to each other, and the first mold body 1 and the second mold body 2 are connected by a connecting component 4 to form a mold body with a hollow cavity 3;

[0039] Steps 5 are provided at opposite positions on the sides of the first mold body 1 and the second mold body 2, and the bottom plates of the first mold body 1 and the second mold body 2 each have multiple spaced connecting holes 6.

[0040] In this embodiment, the first mold body 1 and the second mold body 2 are connected by the connecting component 4 to form a mold body with a hollow cavity 3, which is used to cast the support at the residential exhaust stairwell floor. The cast support has steps on both sides, which facilitates installation between the shear wall and the reinforced concrete floor slab. The connecting hole 6 of the mold bottom plate is used to fix it with the support template to prevent the support template from being misaligned or floating.

[0041] In some embodiments, both the first mold body 1 and the second mold body 2 can be welded from steel plates with a thickness of 2mm. In a specific embodiment, the total height of the mold is the thickness of the reinforced concrete floor slab h + 50mm, 50mm above the slab surface, to facilitate mold dismantling and turnover after construction. This mold can also control the slab thickness around the pre-reserved hole for the exhaust duct. The outer diameter of the upper h / 2 + 50mm portion of the mold is the pre-reserved size for exhaust duct installation in the design drawings. The outer diameter of the lower h / 2 portion of the mold is reduced by 20mm on each side; this 20mm serves as support for the finished exhaust duct at the floor level. The connecting component 4 includes connecting plates 7 disposed on the first mold body 1 and the second mold body 2. The two connecting plates 7 are arranged opposite each other and abut against each other, and are connected by bolts, making the mold body a cube with an open top.

[0042] Pull rings 8 are connected to the upper side of the first mold body 1 and the upper side of the second mold body 2. The pull rings 8 are made of steel bars and are arc-shaped with a diameter of 150mm.

[0043] Example 2

[0044] like Figure 2 As shown, a cavity pre-reservation component 9 is also installed on the second mold body 2. Specifically, the cavity pre-reservation component 9 includes a first through hole and a second through hole arranged opposite to each other on the second mold body 2. A cavity inner mold 10 is inserted into the first through hole and the second through hole. The cavity inner mold 10 has a circular or rectangular cross-section.

A blind plate 11 is connected to one end of the cavity inner mold 10 and is connected to the side wall of the first through hole by a bolt assembly. A sealing element 12 for sealing the cavity inner mold 10 is provided on the outer periphery of the side wall of the second through hole.

[0045] Before pouring, the inner mold 10 is inserted into the first and second through holes, and the obstruction plate 11 and the second mold body 2 are connected by bolt assemblies. The gap between the inner mold 10 and the second mold body 2 is sealed by the obstruction plate 11 and the sealing element 12 to prevent leakage of colloid during pouring. After the concrete in the hollow cavity 3 is formed, the obstruction plate 11 and the second mold body 2 are removed, and the inner mold 10 is pulled out along the first through hole, so that the poured concrete supports have rectangular or circular cavities.

[0046] Example 3

[0047] like Figure 3 , Figure 4As shown, a concrete thickness adjustment assembly 13 is also installed on the first mold body 1 and the second mold body 2. Specifically, the concrete thickness adjustment assembly 13 includes a connecting screw 14 and a vertical baffle 15. The connecting screw 14 is disposed on the side wall of the first mold body 1 or the second mold body 2. A locking nut 16 is sleeved on the connecting screw 14, and two locking nuts 16 are arranged on both sides of the mold body. The distance of the connecting screw 14 extending into the hollow cavity 3 is adjusted by the cooperation of the locking nuts 16 and the connecting screw 14, thereby adjusting the distance of the horizontal cavity. A permanent magnet 17 is installed at one end of the connecting screw 14, and the vertical baffle 15 is attracted to the end of the permanent magnet 17. The vertical baffle 15 is made of steel plate. By attracting the vertical baffle 15 with the permanent magnet 17, the downward extension distance of the vertical baffle 15 can be precisely adjusted to adjust the vertical downward distance of the cavity. A horizontal baffle 18 is connected to the lower side of the vertical baffle 15 via a dovetail groove assembly. Specifically, the side wall of the vertical baffle 15 is provided with a dovetail groove, and the side of the horizontal baffle 18 is provided with a dovetail protrusion that mates with the dovetail groove. After selecting a suitable horizontal baffle 18 and connecting it to the vertical baffle 15 according to the size of the casting, the first mold body 1 or the second mold body 2, the vertical baffle 15 and the horizontal baffle 18 form a cavity with an open top. The colloid during casting supports the bottom surface of the horizontal baffle 18.
