Description

Technical Field

[0001] The utility model relates to the field of building components, in particular to a prefabricated beam and slab pedestal sealing strip. Background Art

[0002] In the prior art, prefabricated beams and slabs are frequently used in the fields of construction, and one of the greatest difficulties in the use of prefabricated beams and slabs is to improve the appearance quality of the prefabricated beams and slabs. In the traditional solution, the slurry-stopping structure between the prefabricated beam and slab pedestal and the side formwork is to use double-sided tape, and the double-sided tape is clamped between the side formwork and the beam and slab pedestal to form a sealing structure between the prefabricated beam and slab pedestal, the prefabricated beam and slab side formwork, and the prefabricated beam and slab. With such a design, after the preparation is completed and the side formwork is removed, the double-sided tape attached to the side formwork and / or the beam and slab pedestal needs to be removed, and in the process of removing the double-sided tape, there is a risk of the double-sided tape being damaged, and there is also the possibility of incomplete removal, resulting in a low reuse rate of the double-sided tape and affecting the appearance quality of the prefabricated beam and slab. Utility Model Content

[0003] The utility model aims to provide a prefabricated beam slab pedestal sealing strip, which can be reused, reduces the construction cost, has good sealing effect, and is not easy to affect the molding quality of the prefabricated beam slab.

[0004] The embodiment of the utility model is achieved as follows:

[0005] In a first aspect, the utility model provides a prefabricated beam slab pedestal sealing strip, comprising:

[0006] The sealing strip body is arranged in a long strip shape, and has a first side surface and a second side surface arranged in the thickness direction thereof, the first side surface is used to fit with the beam slab pedestal, and the second side surface is provided with a mounting groove, and the mounting groove is used to be engaged with the side mold; a guide column is provided on the bottom wall of the mounting groove, and the guide column is used to be plugged into the side mold.

[0007] In an optional embodiment, the cross-sectional profile of the mounting slot is T-shaped or dovetail-shaped, so that the slot width of the mounting slot is smaller than the width of the slot bottom of the mounting slot; the cross section is a plane perpendicular to the length direction of the sealing strip body.

[0008] Based on the above solution, the structure of the sealing strip body is simple. After being engaged with the side mold, the sealing strip body can be engaged with the side mold, thereby improving the stability of the sealing body after installation. The sealing strip body is not easy to fall off or shift from the side mold, which is beneficial for subsequent use. At the same time, when the side mold is removed, the sealing strip body leaves the beam slab pedestal together with the side mold, and is not easy to adhere to the beam slab pedestal, and is not easy to affect the appearance quality of the beam slab pedestal.

[0009] In an optional embodiment, the sealing strip body also has a first side and a second side arranged opposite to each other in its width direction, and a sealing fold is provided on at least one of the first side and the second side, and the sealing fold is used to be clamped between the beam slab base and the side form.

[0010] Based on the above scheme, the sealing strip body is clamped between the side form and the beam slab pedestal. The sealing strip body forms a sealing belt through the first side and the second side, and also forms a sealing belt through the sealing fold. The two sealing belts cooperate to improve the sealing effect.

[0011] In an optional embodiment, an anti-wrinkle protrusion is provided on the side of the sealing fold for fitting with the side mold.

[0012] Based on the above scheme, a groove matching with the anti-wrinkle protrusion is processed on the side mold. The anti-wrinkle protrusion can be hemispherical, and correspondingly, the groove can be a hemispherical groove. In this way, the anti-wrinkle protrusion can be inserted into the corresponding groove to avoid partial bending or flipping of the sealing fold due to its large length-to-width ratio, which can improve the stability and reliability of the sealing fold, thereby improving the sealing performance.

[0013] In an optional embodiment, there are multiple anti-wrinkle protrusions, and the multiple anti-wrinkle protrusions are arranged at intervals in the length direction of the sealing strip body.

[0014] Based on the above solution, the sealing fold is stabilized by the cooperation of multiple anti-wrinkle protrusions. The probability of deformation of the sealing fold is small, and the use is safe and reliable.

[0015] In an optional embodiment, the guide column includes a positioning shaft segment and a guiding shaft segment of an integrated structure, the positioning shaft segment is configured as an equal diameter segment, the end of the positioning shaft segment away from the guiding shaft segment is connected to the bottom wall of the mounting slot, the guiding shaft segment is configured as a variable diameter segment, and the diameter of the guiding shaft segment gradually decreases in the direction from its end close to the positioning shaft segment to the other end.

[0016] Based on the above scheme, when the sealing strip body is matched with the side mold, the guide column is first inserted into the corresponding plug hole on the side mold. The plug hole is a blind hole, and the smaller end of the guide shaft section is first inserted into the plug hole, which is not easy to cause interference, and the insertion is more flexible and convenient. When the guide shaft section is fully inserted, the positioning shaft section immediately enters the plug hole. The outer diameter of the positioning shaft section is slightly larger than or substantially equal to the hole diameter of the plug hole. The positioning shaft section cooperates with the plug hole to stabilize the sealing strip body. At the same time, the mounting slot is engaged with the side mold to further improve stability.

[0017] In an optional embodiment, the guide column and the sealing strip body are configured as an integral structure.

[0018] Based on the above scheme, the main body of the guide column and the sealing strip is formed in a simple manner, the structure is stable and reliable, the service life is long, and it is also conducive to mass production with low processing and manufacturing costs.

[0019] In an optional embodiment, an arc-shaped groove is provided on the first side surface, the length of the arc-shaped groove is consistent with the length direction of the sealing strip body, and the width of the arc-shaped groove is consistent with the width direction of the sealing strip body.

[0020] Based on the above solution, when the sealing strip body is deformed under extrusion, the space between the arc-shaped groove of the sealing strip body and the beam slab pedestal can provide the space required for deformation, so that the sealing strip body can better fit the surface of the beam slab pedestal.

[0021] In an optional embodiment, the sealing strip body is configured as a rubber piece.

[0022] Based on the above solution, the cost of the sealing strip main body is low.

[0023] The beneficial effects of the embodiments of the utility model are:

[0024] In summary, the prefabricated beam and slab pedestal sealing strip provided in this embodiment can be detachably connected to the side formwork through the cooperation of the installation slot and the guide column. When the side formwork and the beam and slab pedestal are installed and matched by fasteners such as tension bolts, the sealing strip body is positioned together with the side formwork at the set position of the beam and slab pedestal. For example, an installation groove is formed on the side of the beam and slab pedestal, and the sealing strip body is just embedded in the installation groove. After the side forms on both sides of the beam and slab pedestal are fastened by tension bolts, the sealing strip body is squeezed and deformed, which plays a role in sealing the connection gap between the beam and slab pedestal and the side formwork, and is not easy to leak when pouring concrete. After the pouring is completed and the concrete solidifies to meet the standards, the side formwork is removed, and the sealing strip body leaves the beam and slab pedestal together with the side formwork, and is not easy to adhere to the surface of the beam and slab pedestal. The sealing strip body can be directly used for the next time, reducing construction costs. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] In the prior art, double-sided tape is used to adhere between the side mold 001 and the beam slab pedestal 002 to play a sealing role and reduce the probability of leakage. However, after the concrete is poured, the double-sided tape needs to be destroyed, which has a high cost of use, and part of the double-sided tape adheres to the beam slab pedestal 002, affecting the molding quality.

[0038] In view of this, the designer provides a prefabricated beam and slab pedestal sealing strip, which is reusable, low in cost, and not easy to adhere to the beam and slab pedestal 002, and is not easy to affect the appearance quality of the beam and slab pedestal 002.

[0039] Please combine Figure 1-Figure 3 In this embodiment, the sealing strip of the prefabricated beam slab pedestal includes a sealing strip body 100, which is arranged in a long strip shape. The sealing strip body 100 has a first side surface 110 and a second side surface 120 arranged in the thickness direction thereof. The first side surface 110 is used to fit with the beam slab pedestal 002. The second side surface 120 is provided with an installation slot 130, which is used to be snap-fitted with the side mold 001. A guide column 140 is provided on the bottom wall of the installation slot 130, which is used to be plug-fitted with the side mold 001.

[0040] Based on the above, the use of the prefabricated beam slab pedestal sealing strip provided in this embodiment is as follows:

[0041] The sealing strip body 100 is detachably connected to the side mold 001 by the cooperation of the installation slot 130 and the guide column 140. When the side mold 001 is installed and matched with the beam and slab pedestal 002 by using the fasteners 003 such as the tension bolts, the sealing strip body 100 is positioned together with the side mold 001 at the set position of the beam and slab pedestal 002. For example, a mounting groove 021 is formed on the side of the beam and slab pedestal 002, and the sealing strip body 100 is just embedded in the mounting groove 021. After the side molds 001 on both sides of the beam and slab pedestal 002 are fastened by the tension bolts, the sealing strip body 100 is squeezed and deformed, which plays the role of sealing the connection gap between the beam and slab pedestal 002 and the side mold 001, and it is not easy to leak when pouring concrete. After pouring is completed and the concrete solidifies to meet the standards, the side form 001 is removed, and the sealing strip body 100 leaves the beam and slab pedestal 002 together with the side form 001, and is not easily attached to the surface of the beam and slab pedestal 002. The sealing strip body 100 can be directly used next time, reducing construction costs.

[0042] It should be understood that both sides of the beam slab pedestal 002 can be formed with mounting grooves 021, and the sealing is achieved between the side molds 001 on both sides through the corresponding sealing strip bodies 100. The side molds 001 on each side and the beam slab pedestal 002 are matched in the same way. In order to avoid repeated description, the structure of one side is used as an example for description in this embodiment.

[0043] In addition, a dovetail-shaped or T-shaped clamping column 011 that cooperates with the mounting slot 130 can be provided on the side mold 001.

[0044] The following embodiments illustrate the details of the prefabricated beam and slab pedestal sealing strip provided in the present application by way of examples.

[0045] In this embodiment, optionally, the cross-sectional profile of the mounting slot 130 is T-shaped or dovetail-shaped, so that the slot width of the mounting slot 130 is smaller than the width of the slot bottom of the mounting slot 130; the cross section is a plane perpendicular to the length direction of the sealing strip body 100.

[0046] With such a design, the structure of the sealing strip body 100 is simple. After being snap-fitted with the side mold 001, the sealing strip body 100 can be engaged with the side mold 001, thereby improving the stability of the sealing body after installation. The sealing strip body 100 is not easy to fall off or shift from the side mold 001, which is convenient for subsequent use. At the same time, when the side mold 001 is removed, the sealing strip body 100 leaves the beam slab pedestal 002 together with the side mold 001, and is not easy to adhere to the beam slab pedestal 002, and is not easy to affect the appearance quality of the beam slab pedestal 002.

[0047] In this embodiment, optionally, the sealing strip body 100 also has a first side and a second side that are relatively arranged in its width direction, and a sealing folded edge 150 is provided on at least one of the first side and the second side, and the sealing folded edge 150 is used to be clamped between the beam slab base 002 and the side mold 001.

[0048] With such a design, the sealing strip body 100 is clamped between the side mold 001 and the beam slab base 002. The sealing strip body 100 forms a sealing belt through the first side surface 110 and the second side surface 120, and also forms a sealing belt through the sealing fold 150. The cooperation of the two sealing belts can improve the sealing effect.

[0049] For example, the sealing flange 150 may be provided from both the first side and the second side.

[0050] Furthermore, an anti-wrinkle protrusion 160 is provided on the side of the sealing fold 150 for fitting with the side mold 001.

[0051] With such a design, a groove cooperating with the anti-wrinkle protrusion 160 is processed on the side mold 001. The anti-wrinkle protrusion 160 may be hemispherical, and correspondingly, the groove may be a hemispherical groove. In this way, the anti-wrinkle protrusion 160 can be inserted into the corresponding groove to avoid partial bending or flipping of the sealing fold 150 due to its large length-to-width ratio, thereby improving the stability and reliability of the sealing fold 150 and thus improving the sealing performance.

[0052] Optionally, there are multiple anti-wrinkle protrusions 160 , and the multiple anti-wrinkle protrusions 160 are arranged at intervals in the length direction of the sealing strip body 100 .

[0053] It is worth noting that the sealing fold 150 is stabilized by the cooperation of a plurality of anti-wrinkle protrusions 160. The sealing fold 150 has a low probability of deformation and is safe and reliable to use.

[0054] In this embodiment, optionally, the guide column 140 includes a positioning shaft segment 141 and a guiding shaft segment 142 of an integrated structure, the positioning shaft segment 141 is configured as an equal diameter segment, the end of the positioning shaft segment 141 away from the guiding shaft segment 142 is connected to the bottom wall of the mounting slot 130, and the guiding shaft segment 142 is configured as a variable diameter segment, and the diameter of the guiding shaft segment 142 gradually decreases in the direction from its end close to the positioning shaft segment 141 to the other end.

[0055] With such a design, when the sealing strip body 100 is matched with the side mold 001, the guide column 140 is first inserted into the corresponding insertion hole 012 on the side mold 001. The insertion hole 012 is a blind hole, and the smaller end of the guide shaft section 142 is first inserted into the insertion hole 012, which is not easy to cause interference, and the insertion is more flexible and convenient. When the guide shaft section 142 is fully inserted, the positioning shaft section 141 immediately enters the insertion hole 012. The outer diameter of the positioning shaft section 141 is slightly larger than or substantially equal to the aperture of the insertion hole 012. The positioning shaft section 141 cooperates with the insertion hole 012 to stabilize the sealing strip body 100. At the same time, the mounting slot 130 is engaged with the side mold 001 to further improve stability.

[0056] In an optional embodiment, the guide column 140 and the sealing strip body 100 are configured as an integrated structure.

[0057] With such a design, the guide column 140 and the sealing strip body 100 are formed in a simple manner, have a stable and reliable structure, have a long service life, are conducive to mass production, and have low processing and manufacturing costs.

[0058] In an optional embodiment, an arc-shaped groove is provided on the first side surface 110 , the length of the arc-shaped groove is consistent with the length direction of the sealing strip body 100 , and the width of the arc-shaped groove is consistent with the width direction of the sealing strip body 100 .

[0059] With such a design, when the sealing strip body 100 is deformed under extrusion, the space between the arc-shaped groove of the sealing strip body 100 and the beam slab base 002 can provide the space required for deformation, so that the sealing strip body 100 can better fit the surface of the beam slab base 002.

[0060] It should be understood that the sealing strip body 100 can be configured as a rubber member. The sealing strip body 100 has low cost and good sealing effect.

[0061] The prefabricated beam and slab pedestal sealing strip provided in this embodiment can cooperate with the side form 001 and the beam and slab pedestal 002 to play a sealing role and prevent leakage of concrete during the pouring process. At the same time, the sealing strip can be reused to reduce construction costs.
