Abstract
Description
Technical Field
[0001] The invention relates to the technical field of building repair, and in particular to a method and a structure for repairing leakage at a deformation joint at the bottom of a beam. Background Art
[0002] Leakage from deformation joints at the bottom of beams is a common problem in building structures and needs to be repaired in a timely manner. The following is the current status of the common methods for repairing leakage from deformation joints at the bottom of beams:
[0003] (1) Bolt pressure filling: Bolts are installed between the bottom plate of the beam and the support, and the pressure of the bolts is used to fill the gap at the bottom of the beam. This method is suitable for situations where the gap is small and can effectively prevent water penetration. However, due to the small gap, the filling range of the bolts is limited. In addition, it is difficult for the bolts to fit or fix completely during the filling process, which may cause the risk of water leakage.
[0004] (2) Sealing material filling: Use appropriate sealing materials to fill the gaps at the bottom of the beam, such as silicone, polyurethane, etc. These materials have good viscosity and weather resistance, and can effectively seal the gaps to prevent water penetration. However, the viscosity and weather resistance of the sealing material may not be sufficient to maintain a stable waterproof layer for a long time, and improper or uneven filling during the process may cause water leakage.
[0005] (3) Expansion tape: Select appropriate expansion tape and embed it into the crack between the beam bottom plate and the support. It will expand and fill the gap when it comes into contact with water. This method has high strength and good sealing performance and can adapt to the deformation of the beam bottom. The expansion tape expands and fills the gap after contact with water, but its viscosity and durability may be affected by environmental factors such as temperature and humidity. Long-term use may cause the viscosity to decrease or fail.
[0006] (4) Spraying waterproof materials: Spraying waterproof materials is used to coat the bottom of the beam to form a waterproof layer, which effectively prevents water penetration. This method can cover the entire bottom area of the beam and adapt to situations with large deformation. However, the control of construction technology and material quality is crucial to the stability and durability of the effect. Improper construction may result in uneven coating or missing coating.
[0007] (5) Caulking glue treatment: Caulking glue treatment has a certain effect in filling gaps, but its durability and bonding effect depend on the quality of the caulking glue material and the accuracy of the construction operation. Some conditions such as temperature changes, ultraviolet radiation, etc. may cause the caulking glue to age or fail. Caulking glue treatment has a certain effect in filling gaps, but its durability and bonding effect depend on the quality of the caulking glue material and the accuracy of the construction operation. Some conditions such as temperature changes, ultraviolet radiation, etc. may cause the caulking glue to age or fail. Summary of the invention

[0015] S5. Wrap an auxiliary cloth strip around the covering cloth.
[0016] The above-mentioned method for repairing the deformation joint of the bottom of the beam covers the bottom of the beam with the cloth main body of the covering cloth, so that the gap at the bottom is covered with a waterproof layer; at the same time, the plug-in ends at both ends of the cloth main body are used as drainage grooves, so that water droplets condensed on the cloth main body can be drained from the bottom of the beam to the supporting structures at both ends and flow away along the supporting structures.

[0034] The “first” and “second” mentioned in the present invention do not represent specific quantities and orders, but are merely used to distinguish names.
[0035] On the one hand, if Figure 1 As shown, a method for repairing a deformation joint at the bottom of a beam in one embodiment of the present invention comprises the following steps:
[0036] S1. Measure the beam to get the bottom size of the beam;
[0037] S2. Cut the PVC coated cloth according to the size of the beam bottom, and cut the PVC coated cloth into a covering cloth, wherein the covering cloth includes a cloth body and plug-in ends arranged at both ends of the cloth body;
[0038] S3, fixing the covering cloth on the beam body, with the plastic-coated surface of the covering cloth facing upwards and in close contact with the beam body;
[0039] S31, the covering width of the covering cloth body is greater than half of the circumference of the side of the beam body; the covering cloth is fixed to the beam body by nails shot by a nail gun. Specifically, by increasing the area of the beam body covered by the cloth body, the waterproof effect of the cloth body is enhanced.
[0040] S4. Insert the plug-in ends on both sides of the covering cloth into the deformation joint of the supporting structure. The plug-in ends at both ends of the cloth body extend beyond the end face of the beam body, and the length of the extended portion is greater than 0.4m. The plug-in ends at both ends of the cloth body extend beyond the end face of the beam body by 0.5m, and the width of the plug-in ends gradually decreases.
[0041] S5. Wrap an auxiliary cloth strip around the covering cloth.
[0042] The above-mentioned method for repairing the deformation joint of the bottom of the beam covers the bottom of the beam with the cloth main body of the covering cloth, so that the gap at the bottom is covered with a waterproof layer; at the same time, the plug-in ends at both ends of the cloth main body are used as drainage grooves, so that water droplets condensed on the cloth main body can be drained from the bottom of the beam to the supporting structures at both ends and flow away along the supporting structures. The overall structure is stable and reliable, and can avoid the problems of unstable effect and poor durability commonly existing in traditional methods.
[0043] On the other hand, Figure 2 and Figure 3 , Figure 4As shown, a beam bottom deformation joint repair structure in one embodiment of the present invention includes a covering cloth 2 arranged at the bottom of the beam body 1, and the covering cloth 2 includes a cloth body 21 and plug-in ends 22 arranged at two length sides of the cloth body 21; the plug-in ends 22 are used to insert into the deformation joint of the supporting structure. In this way, the bottom of the beam body 1 is covered with the cloth body 21 of the covering cloth 2, so that the gap at the bottom is covered with a waterproof layer; at the same time, the plug-in ends 22 at both ends of the cloth body 21 are used as drainage grooves, so that the water droplets condensed by water vapor in the cloth body can be drained from the bottom of the beam body to the supporting structures at both ends, and flow away along the supporting structures. The overall structure is stable and reliable, and can avoid the problems of unstable effect and poor durability commonly existing in traditional methods.
[0044] In one embodiment, the covering cloth is a waterproof cloth such as PVC coated cloth, waterproof canvas, etc.
[0045] In one embodiment, the width side of the cloth body 21 is fixed to the beam body 1 through a fixing member 3. Specifically, the fixing member 3 is a nail shot by a nail gun.
[0046] In one embodiment, an auxiliary cloth strip 4 is further included which is wrapped around the cloth body 21. Specifically, the material of the auxiliary cloth strip 4 is PVC coated cloth, the same as the covering cloth 2. Thus, by wrapping the auxiliary cloth strip 4 around the cloth body 21, it can work together with the fixing member 3, so that the cloth body 21 is in closer contact with the bottom of the beam body 1; at the same time, the structural strength of the auxiliary cloth strip 4 itself can strengthen the structural strength of the beam body 1, thereby fundamentally reducing the possibility of further deformation of the beam body 1.
[0047] In one embodiment, the auxiliary cloth strip 4 includes a first cloth strip and a second cloth strip; the first cloth strip and the second cloth strip are arranged in reverse spirals and form a cross point, the fixing member 3 forms a fixed point with the beam body 1, and the cross point coincides with the fixed point. In this way, by coinciding the cross point with the fixed point, the connection strength between the covering cloth 2 and the beam body 1 can be strengthened, and the durability and weather resistance of the leak repairing structure can be strengthened; at the same time, the double spiral arrangement of the first cloth strip and the second cloth strip can strengthen the structural strength of the beam body 1 and fundamentally reduce the possibility of the beam body 1 continuing to deform.
[0048] In one embodiment, an elastic metal sheet is provided inside the auxiliary cloth strip 4. Specifically, the fixing member 3 passes through the elastic metal sheet to fix the auxiliary cloth strip 4 to the beam body 1. In this way, the structural strength of the leak repair structure can be improved by the elastic metal sheet; at the same time, when the beam body 1 is subjected to a large impact force, the elastic metal sheet can absorb part of the impact force of the beam body 1 through its elastic buffering effect, thereby enhancing the deformation recovery limit of the beam body 1 and reducing the possibility of the beam body 1 continuing to deform.
[0049] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0050] The above-mentioned embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
