[0029] The technical scheme in the embodiments of the present application will be described clearly and completely in combination with the drawings in the embodiments of the present application, obviously, the described embodiments are only some of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all the other embodiments obtained by the ordinary skilled in the art without creative labor are within the protection scope of the present application.

[0030] Please refer to Figure 1 - Figure 5 As shown in the figure, a building structural joint design connecting structure comprises a first bridge body 1 and a second bridge body 2.

[0031] The first bridge body 1 and the second bridge body 2 are respectively provided with a first support part 3 and a second support part 4 on the side close to the structural joint, and the first support part 3 and the second support part 4 are located at the upper part of the structural joint.

[0032] The first support part 3 and the second support part 4 are staggered, and a gap is left between the first support part 3 and the second support part 4; the first support part 3 and the second support part 4 are both right-angled trapezoidal structures, with the right-angled sides flush with the bridge deck and the bottom slope flush with the horizontal plane ( Figure 3 The angle between the support plates (shown as dashed lines) is 5°-10°. Arranging the support plates into a right-angled trapezoidal structure increases connection strength, provides greater support, and facilitates the passage of pedestrians and vehicles. Furthermore, the staggered arrangement of the first support portion 3 and the second support portion 4 leaves a gap, providing space for the bridge to expand and contract, allowing a small amount of rainwater to enter the structural joints.

[0033] The spacing between the structural joints of the first bridge body 1 and the second bridge body 2 depends on the actual situation and can be any value such as 100 mm, 200 mm or 300 mm.

[0034] A plurality of protrusions 9 are evenly distributed on the end surface of the first bridge body 1 and the end surface of the second bridge body 2 in the structural seam, and the protrusions 9 are cylindrical structures.

[0035] The structural gap between the first bridge body 1 and the second bridge body 2 is further filled with rubber blocks 10 .

[0036] The protrusions 9 are symmetrically provided with fixing plates 5, which are fixed to the protrusions 9 on both sides by screws through nail holes 6. The fixing plates 5 provide fixing points for the rubber block 10, increase the stability of the rubber block 10, and enable prefabrication and assembly of the spring 7 and steel rope 8, improving convenience.

[0037] Multiple springs 7 are fixed to the fixed plate 5, and the two ends of the spring 7 are respectively connected to the fixed plates 5 on both sides; multiple steel ropes 8 are symmetrically arranged on both sides of the spring 7, and the two ends of the steel ropes 8 are respectively fixed to the fixed plates 5 on both sides; the arrangement of the steel ropes 8 can help fix the rubber block 10 when the first bridge body 1 and the second bridge body 2 move in opposite directions.

[0038] The rubber block 10 is cast and filled in the structural gap between the first bridge body 1 and the second bridge body 2, and the rubber block 10 is located below the first support part 3 and the second support part 4; the two sides of the rubber block 10 are respectively attached to the end faces of the first bridge body 1 and the end faces of the second bridge body 2; the protrusion 9, the fixing plate 5, the spring 7, and the steel rope 8 are all located in the rubber block 10 and are filled and wrapped by the rubber block 10; the upper part of the rubber block 10 is an inverted V-shaped structure, and the lower part is a rectangular structure.

[0039] The upper surface of the rubber block 10 is coated with a waterproof layer 11; the waterproof layer 11 is in contact with the upper surface of the rubber block 10; the angles of the bottom of the first support portion 3 and the second support portion 4 are set so that a gap is left between the support plate and the rubber block 10, which can facilitate rainwater to enter through the gap formed between the first support portion 3 and the second support portion 4, allowing debris to flow onto the waterproof layer 11, thereby avoiding the accumulation of mud in the structural joint, which in turn affects the functioning of the structural joint.

[0040] In order to facilitate the understanding of the above technical scheme of the utility model, the working principle or operation mode of the utility model in the actual process is explained in detail as follows:

[0041] Before the bridge is formally put into use: the construction workers can set up the coaming according to the bottom and the two sides inside the structural joint, the inside space of the structural joint is surrounded by the coaming into the cavity with the upper part being triangular and the lower part being rectangular, then the molten rubber is poured into the inside from the top of the triangular cavity, the used coaming is taken out after solidification, and after the rubber solidifies, a layer of polyurethane waterproof paint is coated on the top of the rubber to form the waterproof layer 11.

[0042] When the bridge is formally put into use: in the rainy environment, after the rainwater enters the structural joint through the first supporting part 3 and the second supporting part 4, it flows onto the waterproof layer 11, can wash away the entering dust from the two sides of the bridge body, avoids the accumulation of soil in the structural joint, and further affects the function of the structural joint; the spring 7, the steel rope 8 and the protruding block 9 in the structural joint are filled and wrapped by the rubber, the rubber can not only protect the spring 7 and the like from being eroded by the rainwater, but also can form a damping effect with the spring 7 when the bridge body expands and contracts, improve the buffering, in addition, the rubber can also deform along with the thermal expansion and contraction of the bridge body, and protect the bridge body, wherein, since the rubber is filled in the inside of the structural joint, when the bridge body expands and contracts, the force generated by the expansion and contraction can be uniformly resisted, compared with the buffering by the spring 7 alone, the local force can be dispersed on the entire section of the bridge body, so that local damage is avoided, in addition, since the spring 7 is arranged in the inside of the rubber, displacement is difficult to occur, so that the spring 7 will not lose the effect of resisting the force of the thermal expansion and contraction of the bridge body.

[0043] When the bridge body expands due to temperature change or shakes due to wind force, since the structural joint is reserved, the bridge body can move to one side of the structural joint, and conversely, when the bridge body contracts, the bridge body can also avoid being stretched with each other, so that the bridge body is prevented from being cracked, the service life and the use effect are affected, and the use of the spring 7 can buffer the rubber block 10 when the bridge body shakes under the influence of strong wind, so that the damping effect is achieved, and the shaking and deformation degree of the bridge is reduced.

[0044] The spring 7, the steel rope 8 and the protruding block 9 and the like in the utility model are filled and wrapped by the rubber, and the advantages of the rubber filling are as follows: firstly, the rubber can deform along with the thermal expansion and contraction of the bridge body, and protect the bridge body; secondly, the filled rubber can protect the spring 7 from being eroded by the rainwater; and finally, the rubber can also form a damping effect with the spring 7, and improve the buffering effect.

[0045] In the description of the specification, the description of the terms "one embodiment", "an example", "a specific example" and the like means that the specific features, structures, materials or characteristics described in connection with the embodiment or example are included in at least one embodiment or example of the present application. In the present specification, the illustrative description of the above terms does not necessarily mean the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner.
