Description

Technical Field

[0001] The utility model relates to the technical field of flue pipe sealing, in particular to a multi-section prefabricated template. Background Art

[0002] Flue pipe seal prefabrication is a prefabricated element used to seal the flue pipe of a building. Flue pipe refers to the pipe system used to remove exhaust gas, smoke or other pollutants produced by combustion. In a building, the flue pipe is usually located in areas such as the kitchen, bathroom, heating system, etc.

[0003] Common refractory brick flue seals are prefabricated in a variety of shapes, such as right-angle and square, and can be customized according to different flue shapes and sizes. However, existing right-angle and square flue seals have some shortcomings: the right-angle flue seal is not convenient for wall sealing, and a large amount of mortar cement is required to coat the joints, and the stability of the joints is poor; the square flue seal is an integral structure, and there is no need to connect with the wall. It only needs to ensure the stability of the connection with the wall. However, the side of the square flue seal close to the wall will occupy part of the space due to its overall structural design. The side close to the wall is not only redundant but also occupies space, resulting in a waste of resources.

[0004] The prior art patent with publication number CN2138559858U discloses an L flue processing mold. By adopting a first bearing plate and a second bearing plate structure, the first hinge seat and the second hinge seat are used to realize the rotation of the first bearing plate relative to the second bearing plate. Combined with the effect of the angle steel, the rotation positioning of the first bearing plate and the second bearing plate can be realized. It is convenient and fast to use and easy to demould. However, the flue pipe seal processed by the flue processing mold disclosed in the above prior art cannot solve the problem of stability of the connection between the right-angle flue pipe seal and the wall. Based on the above, the present application proposes a multi-segment prefabricated template for the existing right-angle flue pipe seal to ensure increased stability when connected to the wall in the later stage.

[0022] The technical solution of the utility model will be described clearly and completely in conjunction with the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Reference Figure 1-3 A multi-section prefabricated template includes a right-angle template body 100 and a frame edge structure arranged inside the template body 100, a plurality of spacer bars 140 are arranged inside the template body 100, and a plurality of prefabricated spaces 150 are separated by the spacer bars 140 within the frame edge structure;

[0024] The frame edge structure is provided so that the prefabricated pipe seal to be manufactured can be formed within the range, and the provision of a plurality of spacer bars 140 forms a plurality of prefabricated spaces 150, so that the formed prefabricated pipe seal can be divided into multiple parts, ensuring that it can be installed in sections during the later assembly process, thus avoiding the inconvenience of assembly and transportation of the integrated prefabricated pipe seal.

[0025] A plurality of hanging nets 130 corresponding to both sides of the prefabricated space 150 are placed on one side of the frame edge structure close to the template body 100 , and a plurality of positioning strips 160 corresponding to both sides of the prefabricated space 150 are provided in the frame edge structure.

[0026] The setting of the hanging net 130 and the positioning strip 160 is used as a medium to connect the prefabricated pipe seal with the wall. After the hanging net 130 and the positioning strip 160 prefabricated pipe seal are connected as a whole, they can be used as an extension section of the prefabricated pipe seal corresponding to the wall; for the prefabricated pipe seal that has been formed on the prefabricated template, firstly, the positioning strip 160 is a strip with an opening, and the strip is easy to bend. When it is necessary to complete the connection with the wall, the positioning strip 160 is bent at the joint between the prefabricated pipe seal and the wall. After completion, the fixing screws are installed at the opening of the positioning strip 160 to fix it to the wall; in addition, the hanging net 130 can also be bent and deformed. After completing the connection between the positioning strip 160 and the wall, the prefabricated pipe seal can be stably connected to the wall by bending the hanging net 130 to make it adhere to the wall surface, and then coating cement mortar on the outside of the hanging net 130.

[0027] In some embodiments, the frame edge structure includes a first frame edge strip 110 disposed on the front and rear sides of the template body 100 and a second frame edge strip 120 disposed on the left and right sides thereof, and the ends of the first frame edge strip 110 and the second frame edge strip 120 cooperate with each other. The placement of the second frame edge strip 120 is to facilitate rapid demoulding after the prefabricated tube seal is made, that is, the second frame edge strip 120 is movably connected, and can be quickly overlapped before making the prefabricated tube seal, and the operation is simple.

[0028] In some embodiments, the ends of the first frame side strip 110 and the spacer strip 140 are wedge-shaped, and the second frame side strip 120 is a trapezoidal strip; one of the trapezoidal sides of the second frame side strip 120 is respectively plugged into the wedge-shaped sides of the first frame side strip 110 and the spacer strip 140. The wedge-shaped design of the first frame side strip 110 and the spacer strip 140 can provide the basic conditions for the connection and positioning of the trapezoid of the second frame side strip 120, and the trapezoid of the second frame side strip 120 can cooperate with the wedge-shaped side, that is, the second frame side strip 120 can slide along the template body 100 so that its trapezoidal side can be plugged into the wedge-shaped side of the first frame side strip 110 and the spacer strip 140, and vice versa, the reverse sliding can even disconnect the second frame side strip 120 from the first frame side strip 110 and the spacer strip 140.

[0029] In some embodiments, the second frame side strip 120 is provided with a reserved hole 121 corresponding to the prefabricated space 150, and the positioning strip 160 is adapted to the reserved hole 121. The positioning strip 160 movably passes through the reserved hole 121 and extends to the outside on both sides. The setting of the reserved hole 121 provides a position for the positioning strip 160 to be installed. After the positioning strip 160 is installed at the position, the prefabricated tube seal can be directly wrapped and clamped on the positioning strip 160 during the production process, without the need to manually support the positioning strip 160.

[0030] In some embodiments, the reserved hole 121 is provided with a magnetic block 122, and the positioning bar 160 is a metal bar, and the magnetic block and the metal bar are magnetically attracted. The arrangement of the magnetic block 122 in the reserved hole 121 can facilitate the metal positioning bar 160 inserted in the reserved hole 121 to achieve a fixing effect, and prevent the positioning bar 160 from sliding down along the direction of the reserved hole 121 due to gravity and slipping out.

[0031] In some embodiments, the spacer bar 140 is a wavy bar. The wavy bar design of the spacer bar 140 can facilitate the connection between the prefabricated tube seals, and the wavy design makes the adjacent sides of the prefabricated tube seals irregular in shape but corresponding to each other, so the prefabricated tube seals are matched with irregular wavy bands so that they will not be skewed or offset, and avoid poor stability between adjacent sections of prefabricated tube seals due to the flat side design.

[0032] In some embodiments, the template body 100 is paved with an anti-sticking film 170 corresponding to the prefabricated space 150. The anti-sticking film 170 includes but is not limited to polyethylene film and polyvinyl chloride film. The waterproof, anti-sticking film 170 has moisture-proof and anti-stick properties, and can be used as an isolation layer in the prefabrication process of the prefabricated pipe seal to prevent cement from sticking to the mold surface. In addition, the surface of the anti-sticking film 170 is covered with raised particles, which can form static friction with the hanging net 130, so that before the second frame edge strip 120 is installed, the anti-sticking film 170 placed on the template body 100 is prevented from sliding down by the mutual friction between the raised particles and the anti-sticking film 170.

[0033] Working principle:

[0034] 1. Assembly steps of prefabricated formwork:

[0035] a. Prepare the template body and frame structure:

[0036] First, ensure that the template body 100, the frame edge structure (including the first frame edge strip 110 and the second frame edge strip 120) and the anti-adhesive film 170 are clean and undamaged;

[0037] An anti-adhesive film 170 , such as a polyethylene film or a polyvinyl chloride film, is laid on the formwork body 100 to prevent the cement slurry from adhering to the mold surface and to provide raised particles to increase friction;

[0038] Inside the formwork body 100 , spacer bars 140 are fixed according to design requirements, and these spacer bars divide the prefabricated space 150 into a plurality of prefabricated spaces 150 ;

[0039] b. Install the hanging net and positioning strips:

[0040] Corresponding to the two sides of the prefabricated space 150, the hanging net 130 is installed. The hanging net 130 should be placed flatly on the anti-adhesive film 170 on the inner side of the template body 100 to ensure that it is aligned with the side of the prefabricated space 150;

[0041] In the second frame edge strip 120 of the frame edge structure, install the positioning strip 160 into the reserved hole 121. If the magnetic block 122 is used, ensure that the metal positioning strip 160 is magnetically attracted to the magnetic block 122, and check that both ends of the positioning strip 160 extend to the outside of the reserved hole 121 respectively.

[0042] c. Assemble the frame edge structure:

[0043] Install the second frame edge strip 120 on the inner side of the template body 100, slide the second frame edge strip 120 along the inner side of the template body 100 and press the hanging net 130, slide until the trapezoidal side of the end of the second frame edge strip 120 cooperates with the wedge-shaped side of the first frame edge strip 110, and check that the trapezoidal side of the second frame edge strip 120 and the wedge-shaped side of the spacer strip 120 cooperate with each other; the second frame edge strip 120 is movably connected so that it can be quickly demoulded after the prefabricated tube seal is made.

[0044] 2. Forming and installation steps of prefabricated pipe seal:

[0045] a. Mixed cement slurry:

[0046] According to the design requirements, prepare an appropriate amount of cement slurry to ensure it has good fluidity and appropriate consistency;

[0047] b. Pour cement slurry:

[0048] Using a sliding film device, cement slurry is evenly filled in the prefabricated space 150 of the formwork body 100. The sliding film device can help control the flow of cement slurry to ensure that it is evenly distributed in the prefabricated space;

[0049] c. Molding and curing:

[0050] After the cement slurry is poured in, it is waited for to solidify inside the formwork. During the solidification process, the cement slurry will combine with the hanging mesh 130 and the positioning strip 160 to form a prefabricated pipe sealing structure;

[0051] d. Demoulding:

[0052] When the cement slurry is completely cured, the prefabricated pipe seal is removed from the first frame edge strip 110 and the spacer strip 140 in the formwork body 100 through the second frame edge strip 120 that is movably connected. This step should be performed carefully to avoid damaging the prefabricated pipe seal.

[0053] e. Inspection and repair:

[0054] After demoulding, check whether the size and shape of the prefabricated pipe seal meet the design requirements. If necessary, make necessary adjustments to ensure the quality of the prefabricated pipe seal.

[0055] f. Installation and connection:

[0056] At the construction site, the prefabricated pipe seal is installed to the corresponding position according to the design requirements, the positioning strip 160 is accurately positioned using fixing screws, and the hanging net 130 is connected to the wall by coating cement mortar. After the installation is completed, check and ensure the stable connection between the prefabricated pipe seal and the wall.

[0057] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
