DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] The utility model provides Figures 1-4A bridge support seat for bridge construction as shown, comprising a support seat base 1 and a support seat top seat 2 provided on the upper side of the support seat base 1. The support seat base 1 and the support seat top seat 2 are parallel to each other. The cross-sectional shapes and area sizes of the support seat base 1 and the support seat top seat 2 are the same. A plurality of mounting holes 4 are provided inside the front and rear sides at the centers of the support seat base 1 and the support seat top seat 2. A metal sleeve A5 is welded to the top end of the support seat base 1, and a metal sleeve B6 is welded to the bottom end of the support seat top seat 2. The inner and outer diameters of the metal sleeve A5 and the metal sleeve B6 are opposite to each other, and the centers of the metal sleeve A5 and the metal sleeve B6 are on the same vertical line. A rubber support seat 8 is connected inside the metal sleeve A5 and the metal sleeve B6. A lower steel plate 7 is provided at the bottom of the rubber support seat 8, and an upper steel plate 9 is provided at the top of the rubber support seat 8. The outer wall of the bottom end of the lower steel plate 7 is fitted to the outer wall of the top end of the support seat base 1, and the outer wall of the top end of the upper steel plate 9 is fitted to the outer wall of the bottom end of the support seat top seat 2. The diameters of the lower steel plate 7, the rubber support seat 8, and the upper steel plate 9 are equal. When installing and using this bridge support seat, first, the rubber support seat 8 and the lower steel plate 7 at its bottom end need to be inserted into the metal sleeve A5. Then, the support seat top seat 2 needs to be lifted and positioned directly above the support seat base 1. Then, slowly lower the support seat top seat 2 until the metal sleeve B6 at the bottom end of the support seat top seat 2 is sleeved outside the rubber support seat 8 and the upper steel plate 9 at its top end, until the outer wall of the top end of the upper steel plate 9 is fitted to the outer wall of the bottom end of the support seat top seat 2. Then, the assembled bridge support seat needs to be hoisted to the position where the bridge needs to be supported until the bottom end of the support seat and the support seat top seat 2 are respectively fitted to the outer wall of the bottom end and the outer wall of the top end of the position where the bridge needs to be supported. Then, special bolts are respectively inserted into the mounting holes 4 inside the support seat base 1 and the support seat top seat 2, and the bridge support seat is firmly installed and fixed at the position where the bridge needs to be supported using the special bolts. In this way, this bridge support seat can play an excellent supporting role in the bridge.

[0022] Such as Figure 1 , Figure 2 and Figure 4As shown in the figure, air pressure support devices 3 are connected between the left and right ends and the front and rear ends of the support base 1 and the support top seat 2. The air pressure support device 3 includes a metal anti - detachment sleeve 12, a metal anti - detachment pillar 13, and a fixed flange 14. Fixed flanges 14 are welded to the top end of the metal anti - detachment sleeve 12 and the bottom end of the metal anti - detachment pillar 13. The metal anti - detachment sleeve 12 is fixed to the outer wall of the bottom end of the support top seat 2 through the fixed flange 14, and the metal anti - detachment pillar 13 is fixed to the outer wall of the top end of the support base 1 through the fixed flange 14. The top end of the metal anti - detachment pillar 13 is inserted into the metal anti - detachment sleeve 12. The air pressure support device 3 further includes a thickened pressure - relief spring 10 and an air pressure plunger 11. The air pressure plunger 11 is fixed to the top end of the metal anti - detachment pillar 13, and the thickened pressure - relief spring 10 is arranged at the top end of the air pressure plunger 11, and the top end of the thickened pressure - relief spring 10 abuts against the inner wall of the top end of the metal anti - detachment sleeve 12. The metal anti - detachment pillar 13 and the air pressure plunger 11 can move up and down inside the metal anti - detachment sleeve 12, and there is an interference fit between the air pressure plunger 11 and the inner wall of the metal anti - detachment sleeve 12.

[0023] As Figure 1 , Figure 2 and Figure 4 shown in the figure, the metal anti - detachment pillar 13 is a solid metal pillar inside. The outer wall of the metal anti - detachment pillar 13 and the inner wall of the metal anti - detachment sleeve 12 are smooth and free of burrs. When the bridge is under pressure, it will sink downward, which will apply the pressure to the bridge support seat, so that the bridge support seat can support the bridge. However, when there is a deflection force due to the heavy pressure on the bridge, the deflection force will cause the bridge support seat to move in the front - rear or left - right direction. At this time, the metal anti - detachment pillar 13 inserted inside the metal anti - detachment sleeve 12 will prevent the deflection force from causing the bridge support seat to tilt, because the metal anti - detachment pillar 13 can only move up and down in the metal anti - detachment sleeve 12, so it can prevent the deflection force from affecting the bridge support seat. And when the heavy pressure on the bridge is greater, at this time the heavy pressure will cause the support top seat 2 to move downward, which will cause the metal anti - detachment sleeve 12 to move downward outside the metal anti - detachment pillar 13, which will compress the thickened pressure - relief spring 10 in the cylinder. At the same time, the upward movement of the air pressure plunger 11 at the top end of the metal anti - detachment pillar 13 will compress the air inside the metal anti - detachment sleeve 12. The compressed air and the thickened pressure - relief spring 10 can resist and buffer the transmitted heavy pressure, so as to increase the support effect and pressure - relief effect of the bridge support seat, making the bridge support seat better support the bridge.

[0024] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
