Description

Technical Field

[0001] The invention relates to the technical field of building wall connection, in particular to a deformable connection structure of a concrete trestle and a construction process thereof. Background Art

[0002] Concrete trestles are a common temporary bridge, generally used to temporarily cross obstacles such as rivers and trenches. Concrete trestles are strong, durable and safe, and are commonly used temporary bridges in road construction. At present, trestles composed of steel structures and concrete are widely used in railway engineering, tunnel construction, power engineering and other fields. Trestles composed of multiple concrete steel structures are also widely used in various practices.

[0003] For example, the Chinese patent CN103352422B is a deformable connection structure of a concrete trestle floor, in which a deformation joint of a certain width is provided between two trestle floors; the lower end surface of the trestle floor connection is usually sealed with iron sheets; the length of the lower end surface connecting the iron sheets between the deformation joints is greater than the actual length of the deformation joints, that is, the lower end surface connecting the iron sheets has a certain surplus; the deformation joint is filled with asphalt hemp; between the upper end surfaces of the two trestle floors that are flush with the upper part of the deformation joint, iron sheets are paved, and the length of the upper end surface connecting the iron sheets between the deformation joints is greater than the actual length of the deformation joints, that is, the upper end surface connecting the iron sheets has a certain surplus; a waterproof membrane is attached to the iron sheet to play a secondary waterproofing role; a cement mortar cushion layer is laid on the waterproof membrane, and asphalt mastic material is used to seal the deformation joints on the waterproof membrane.

[0004] Traditional concrete steel structure trestles need to be connected to concrete building structures when in use. In the prior art, multiple steel nails are usually used for fixed connection. Due to the complex environment in which the concrete steel structure trestles are located, they are easily affected by factors such as temperature changes during use, and relative displacement and deformation are likely to occur between the trestles and the building structure. Ordinary steel nail structures cannot adapt to this relative deformation, which can easily lead to structural stress concentration, and then cracks, connection damage and other problems, which seriously affect the service life and safety of the trestles and increase maintenance costs and operational risks.

[0037] A construction process for a deformable connection structure of a concrete trestle comprises the following steps:

[0038] S1, embedding and placing the embedded steel plate 13 and a plurality of embedded iron rods 14 in the installation position of the concrete building structure and the concrete steel structure trestle, so that the top of the embedded steel plate 13 is pushed upward for a certain length, and one end of the embedded iron rod 14 is extended outward;

[0039] S2. First, install the connection assembly 3 on the concrete steel structure trestle, leave a connection distance between the concrete building structure and the concrete steel structure trestle, then point the multiple connection holes 32 of the cross beam 31 toward the embedded iron rod 14, move the cross beam 31 until one side thereof fits with the concrete steel structure trestle, at this time, one end of the embedded iron rod 14 passes through the rubber ring 310 and extends into the inside of the connection hole 32, then insert the latch rod 37 from top to bottom into the connection hole 32 and the through hole 16, and weld the two ends of the latch rod 37 to the inner wall of the connection hole 32;

[0040] S3, after the latch rod 37 is fixed inside the connection hole 32, a 30 mm thick cement mortar layer 311 is laid at both ends of the latch rod 37, and an iron block 312 with the same size as the inner diameter of the connection hole 32 is welded to the opening of the connection hole 32, and the iron block 312 blocks the connection hole 32, completing the connection and fixation between the multiple pre-embedded iron rods 14 pre-embedded in the concrete steel structure trestle and the connection assembly 3;

[0041] S4. Similarly, according to the above steps, the connection and fixation between the multiple pre-embedded iron rods 14 and the connection components 3 in the concrete building structure are completed, and the positions of the two connection components 3 are aligned with each other. When the deformable component 2 moves from top to bottom, the multiple buffer plates 235 are clamped in the grooves 34, and then the buffer plates 235 are fixed to the beams 31 by expansion bolts 238, and a deformation gap of a certain distance is left between the fixing seat 221 and the beam 31;

[0042] S5. Weld one end of the multiple plug shafts 231 to the corresponding positions on the outside of the beam 31, weld one end of the multiple assembly seats 24 to the corresponding positions on the outside of the beam 31, and finally lay the corrugated iron sheet 11 bonded with the rubber sheet 12 on the upper end surface of the concrete building structure and the concrete steel structure trestle.

Finally, the gap between the corrugated iron sheet 11 and the trestle panel is sealed with a sealant material.

[0043] The working principle of this embodiment is as follows: by setting a deformable component 2, when the concrete trestle structure is displaced and the deformable component 2 is squeezed, the buffer plate 235 can slide in the sliding groove 233 through the sliders 237 at both ends of the buffer plate 235, and the rubber composite plate 239 at one end of the sliding groove 233 is squeezed, and the two plug shafts 231 squeeze the rubber block 230 in the middle, and at the same time, the rotating plate 1 223 and the rotating plate 224 rotate, so that the movable plate 1 225 and the movable plate 226 squeeze the horizontal spring 229 in the middle. In addition, when the two connecting frames 25 rotate, they squeeze the lifting plate 26 downward, thereby squeezing the longitudinal spring 27 downward.

Both the rubber material and the spring have high elasticity and good deformation ability, and can absorb and buffer the deformation energy generated by relative displacement. At the same time, the metal part in the rubber composite plate 239 is embedded in the rubber and distributed in a grid or sheet shape to enhance the overall strength and stability of the structure and prevent the rubber composite plate 239 from being over-deformed and failing. The rubber part in the deformable component 2 can be shear-deformed, and the metal part cooperates with the rubber to resist the deformation force, so that the connection structure can adapt to horizontal displacement without generating excessive stress. While ensuring the tightness of the connection, a certain degree of relative slip is allowed to adapt to the deformation requirements in the horizontal direction;

[0044] By setting the connection component 3, when the concrete trestle structure sinks and displaces and the embedded iron rod 14 squeezes the rubber ring 310, the rubber ring 310 is made of rubber material. Both the rubber material and the spring have high elasticity and good deformation ability, and can absorb and buffer the deformation energy caused by relative displacement. The rubber ring 310 in the connection component 3 plays a buffering role under compression and tension. The metal structure provides lateral support force to maintain the stability of the connection structure and prevent vertical separation or excessive extrusion. While ensuring the tightness of the connection, a certain degree of relative slippage is allowed to adapt to the deformation requirements in the vertical direction, ensuring the overall strength and stability of the structure, so that the connection structure can work reliably under complex stress environments; the deformable connection structure effectively solves the relative displacement and deformation problems of the concrete trestle caused by various factors, avoids structural stress concentration, significantly reduces the risk of cracks and connection damage, and extends the service life of the trestle.

At this time, one end of the embedded iron rod 14 passes through the rubber ring 310 and extends into the inside of the connection hole 32, and then the latch rod 37 is inserted from top to bottom into the connection hole 32 and the through hole 16, and the two ends of the latch rod 37 are welded to the inner wall of the connection hole 32, and a 30 mm thick cement mortar layer 311 is laid at both ends of the latch rod 37, and an iron block 312 of the same size as the inner diameter of the connection hole 32 is welded to the opening of the connection hole 32 (as shown in FIG.

Stability, so that the structure of the present invention can make the concrete steel structure trestle and the concrete building structure more firmly connected. By arranging a waterproof gasket 39 at the connection between the crossbeam 31 and the concrete, the corrugated iron sheet 11 and the extended iron sheet 15 can play a waterproof role. The corrugated iron sheet 11, the extended iron sheet 15 and the waterproof gasket 39 are used for sealing treatment to prevent rainwater, corrosive liquids, etc. from penetrating into the connection part of the connection structure. At the same time, the metal parts of the connection structure are all treated with anti-corrosion measures such as galvanizing and painting, and the rubber part is made of rubber materials with good weather resistance and corrosion resistance, so as to avoid rainwater from eroding the metal parts of the deformable component 2 and the connection component 3, further improving the durability of the entire connection structure in harsh environments, reducing maintenance costs, and improving the overall reliability and safety of the concrete trestle system;

[0050] By setting the deformable component 2, when the concrete trestle structure is displaced and the deformable component 2 is squeezed, the rubber composite plate 239 adopts a special rubber-metal composite structure, and the rubber block 230 is made of rubber material. The rubber material and the spring have high elasticity and good deformation ability, and can absorb and buffer the deformation energy generated by relative displacement. At the same time, the metal part in the rubber composite plate 239 is embedded in the rubber and distributed in a grid or sheet shape to enhance the overall strength and stability of the structure and prevent the rubber composite plate 239 from being over-deformed and failing. The rubber part in the deformable component 2 can be sheared, and the metal part cooperates with the rubber to resist the deformation force, ensuring the tightness of the connection while allowing a certain degree of relative slippage to meet the deformation requirements in the horizontal direction;

[0051] By providing the connection component 3, when the concrete trestle structure sinks and displaces and the embedded iron rod 14 squeezes the rubber ring 310, the rubber ring 310 in the connection component 3 plays a buffering role under compression and tension, and the metal structure provides lateral support force to maintain the stability of the connection structure and prevent vertical separation or excessive extrusion. While ensuring the tightness of the connection, a certain degree of relative slippage is allowed to adapt to the deformation requirements in the vertical direction, thereby ensuring the overall strength and stability of the structure and enabling the connection structure to work reliably in a complex stress environment.
