Description

TECHNICAL FIELD

[0001] The utility model relates to building waterproof technical field, concretely is a building waterproof structure with expansion joint. BACKGROUND

[0002] In the field of building engineering, the treatment of expansion joints is crucial to the stability and waterproof performance of buildings. Expansion joints can effectively cope with the expansion and deformation of buildings due to temperature changes, foundation settlement and other factors, avoiding damage to the structure of the building. As a key material for filling expansion joints, the performance of sealant directly affects the waterproof sealing effect of expansion joints and the overall quality of the building

[0003] Building expansion joints are structural joints set at appropriate positions along the construction joint direction of buildings or structures to reduce the possibility of cracks or damage to the structure caused by thermal expansion and contraction due to changes in climate temperature. Expansion joints divide walls, floors, roofs and other parts into two independent parts, allowing buildings or structures to make horizontal expansion in the longitudinal direction. In building structures, waterproof structures need to be set at positions corresponding to building structure expansion joints to prevent water leakage and seepage.

[0004] REFERENCE Figure 1 Currently, the related art sets expansion joints 11 between building bodies 10, and the construction method is usually to directly fill sealant 9 in the expansion joints 11. After the sealant 9 solidifies, the two sides of the gel (place A in the figure) form a force connection with the building body 10 to achieve the sealing function of the expansion joint 11. However, in actual use, it is found that when the expansion joint 11 expands due to the natural expansion of the building, the stress is concentrated, and only the two sides of the sealant 9 and the expansion joint 11 bear the stress. With the passage of time, the two sides of the gel (place A in the figure) are prone to cracking. Once the two sides of the gel crack, the sealing of the expansion joint 11 will be damaged, leading to water leakage and other problems. UTILITY MODEL CONTENTS

[0006] In view of the deficiencies of the prior art, the utility model provides a building waterproof structure with expansion joints to solve the problem of small stress area of traditional sealant and building body and easy cracking.

[0007] (II) Technical solution

[0008] To achieve the above object, the utility model provides the following technical scheme: a building waterproof structure with expansion joint, expansion joint inside both sides are installed the connecting plate, the connecting plate is fixedly connected with building body, both sides connecting plate has certain distance spacing, every connecting plate side to building body is provided with support piece, support piece is used to form certain gap between connecting plate and building body, sealant is filled in expansion joint, sealant is wrapped in the outside of connecting plate after solidification, both sides of sealant and building body are stressed, connecting plate is stressed in sealant at the same time, and the stress area of sealant is increased.

[0009] Further, the bottom of the connecting plate is provided with a supporting plate, which supports the bottom end of the sealant.

[0010] Further, the supporting plate is slidably connected with each connecting plate.

[0011] Further, the bottom of each connecting plate is provided with a connecting shaft, and the bottom end of each connecting shaft is provided with a limiting block. A plurality of sliding grooves corresponding to the connecting shafts are formed in the supporting plate, and the sliding grooves have a certain length.

[0012] Further, a plurality of through holes are formed in the connecting plate.

[0013] Further, a bolt is installed in the through hole.

[0014] (Three) beneficial effects

[0015] Compared with the prior art, the utility model provides a building waterproof structure with expansion joint, which has the following beneficial effects:

[0016] The building waterproof structure with expansion joint is provided with connecting plates and support pieces, and a certain gap is formed between the connecting plates and the building body. The sealant is filled in the expansion joint. After the sealant solidifies, not only the two sides of the sealant are stressed with the building body, but also the connecting plates wrapped in the sealant participate in the stress, so that the stress area of the sealant is significantly increased. A part of the sealant enters the gap, so that the connection between the two sides of the sealant and the building body is not easy to crack.

[0017] When the expansion joint expands or expands, not only the two sides of the sealant bear the stress, but also the connecting plates in the sealant also share the stress while the two sides of the sealant and the building body are stressed, effectively dispersing the stress and making the stress of the sealant more uniform. The risk of cracking at both ends of the sealant is greatly reduced, thereby ensuring the sealing property of the expansion joint. BRIEF DESCRIPTION OF DRAWINGS

[0028] The technical scheme in the embodiments of the utility model will be described clearly and completely below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without creative labor fall within the protection scope of the utility model.

[0029] Please refer to Figures 2-9 The utility model discloses a building waterproof structure with expansion joint, connecting plate 1, connecting plate 1 installs in the both sides 1 inside expansion joint 11, connecting plate 1 and building body 10 fixed connection, is set up with a plurality of through holes 3 on connecting plate 1, installs bolt 4 in through hole 3, and connecting plate 1 and building body 10 are fixedly connected through screw thread.

[0030] The two side connecting plates 1 have a certain distance spacing to ensure the movement range of the expansion joint 11, and each connecting plate 1 is provided with a supporting piece 2 on the side facing the building body 10, which is a block columnar structure, and the supporting piece 2 is used to form a certain gap between the connecting plate 1 and the building body 10, so that the sealant 9 enters the gap when filling, thereby increasing the stress area and improving the stability of the sealant 9; the sealant 9 filled in the expansion joint 11 is wrapped outside the connecting plate 1 after solidification,

[0031] Instead of only bearing stress on both sides of the sealant 9, the connecting plate 1 also shares the stress in the sealant 9 while the building body 10 bears stress on both sides of the sealant 9, effectively dispersing the stress and making the stress of the sealant 9 more uniform, thereby increasing the stress area of the sealant 9.

[0032] Referring to Figure 1 The expansion joint 11 is provided between the building bodies 10, and the construction method is usually to directly fill the sealant 9 in the expansion joint 11. After the sealant 9 solidifies, the bottom of the sealant 9 (as shown at B in the figure) will sag or collapse over time. The bottom of the connecting plate 1 is provided with a supporting plate 5, which serves to support the bottom end of the sealant 9 to prevent the bottom of the sealant 9 from sagging or collapsing.

[0033] The supporting plate 5 is slidingly connected with each connecting plate 1, and the specific manner is that the bottom of each connecting plate 1 is provided with a connecting shaft 6, the bottom end of each connecting shaft 6 is provided with a limiting block 7, and the supporting plate 5 is provided with a plurality of sliding grooves 8 corresponding to the connecting shafts 6, each sliding groove 8 has a certain length, and the connecting shaft 6 can slide in the sliding groove 8. The limiting block 7 prevents the connecting shaft 6 from slipping out of the sliding groove 8. When the expansion joint 11 expands or contracts due to the natural expansion or contraction of the building or is affected by external environmental factors, the connecting plate 1 fixedly connected with the building body 10 will move to both sides, and since the supporting plate 5 is slidingly connected with the bottom of the connecting plate 1, the supporting plate 5 will not hinder the movement of the connecting plate 1. This not only ensures that the connecting plate 1 can freely and smoothly respond to the changes of the expansion joint 11, but also maintains the stability of the entire waterproof structure in the dynamic process.

[0034] In summary, the building waterproof structure provided with an expansion joint is used by first installing the connecting plate 1 in the expansion joint 11, and then filling the sealant 9 at the position of the connecting plate 1 in the expansion joint 11, and the sealant 9 is tightly bonded to the building body 10 on both sides, and the connecting plate 1 also shares the stress in the sealant 9.

[0035] Although the embodiments of the present application have been shown and described, it is to be understood that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present application, the scope of which is defined by the appended claims and their equivalents.
