Description

TECHNICAL FIELD

[0001] The utility model relates to the field of road and bridge steel support, in particular to a support with adjustable sliding direction. BACKGROUND

[0002] In the field of road and bridge steel support and building steel support at home and abroad, there is a support classification method that divides support types according to the sliding direction of the support. This classification method exists mainly because the support needs to bear different sliding functions at different positions of the bridge and building structure. The structure of the bridge and building, etc. will deform due to temperature changes and structural creep (creep is the deformation of an object that increases with time under load and is not related to the size of the load. Generally, the creep mentioned refers to the creep of concrete), among which the thermal expansion and contraction deformation caused by temperature changes is the main, long-term and periodic structural deformation. The deformation of the bridge and building structure has a deformation center point, where no deformation displacement occurs. The deformation direction of the rest of the structure generally diverges from the center point to the surrounding area, and the deformation displacement direction on the symmetric direction of the center point is opposite. Therefore, when the support is used at different positions of the bridge and building, its displacement direction is also different, which is used to cooperate, adapt and release the deformation of the structure.

[0003] In the layout design of bridge support, the support is divided into longitudinal (bridge direction) support, transverse support, bidirectional (multi-directional) support and fixed support according to the displacement direction. Among them, the longitudinal and transverse supports only allow sliding in the designed longitudinal and transverse directions, and the rest of the direction restricts sliding. The bidirectional support allows sliding in both longitudinal and transverse directions, and the fixed support restricts sliding in both longitudinal and transverse directions. Generally, in road and bridge engineering, the position of each fixed support of the bridge body is set as the deformation displacement center point. The support on the same transverse bridge axis as the fixed support on the same pier cap beam is designed as a transverse support, and the support on the same longitudinal bridge axis as the fixed support on different pier cap beams is designed as a longitudinal support. The rest of the support on the transverse and longitudinal axis of the fixed support is designed as a bidirectional support.

[0004] In actual engineering, due to the uneven construction level of the bridge construction team, the installation error of the support displacement direction is common during project construction, for example, a longitudinal support or bidirectional support is installed at the position designed for transverse sliding. This error is often found during the project completion acceptance or pre-acceptance process. Due to the large size and weight of the bridge body, the length is generally tens of meters, and the weight is several hundred to several thousand tons. Once the support is installed incorrectly, the bridge jacking operation is generally selected, that is, the whole span or whole link bridge is jacked up by a large number of jacks, the support is taken out from the support cushion stone, and the support is installed again after adjusting the sliding direction. The bridge jacking operation has long construction time, high construction difficulty, high risk and high cost.

[0005] In addition to jacking, the rest of the ways to deal with this problem tend to be destructive and non-compliance, such as using flame or plasma cutting to melt and cut off the limit displacement stop bar in the direction of the inside of the support on the pier, and manually welding the limit displacement stop bar on site in the other direction to change the sliding direction of the support. Such methods involve open flame and high temperature, which seriously affect the service life and stability of the rubber structure and the polyethylene sliding plate structure inside the support. At the same time, the stainless steel plate at the lower part of the original support is measured in the limit displacement stop bar, and even if the stop bar is removed, the sliding distance of the support in this direction is also very small. After the support slides beyond the original stop bar position, the sliding friction of the support becomes larger due to the absence of the stainless steel plate, and the sliding plate of the support is scratched and ground flat. The quality of the processed support and the sliding function of the support are difficult to guarantee, and it is difficult to pass the acceptance of the construction unit, quality supervision unit and design unit.

[0027] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0028] like Figs. 1-6 As shown, the adjustable sliding direction support of this utility model includes: a steel plate 1 on the support, a quick-adjustable sliding direction limiting block 2, a reserved limiting bolt hole 3, a stainless steel plate 4, a flat sliding plate 5, an intermediate liner 6, a spherical sliding plate 7, a quick-adjustable sliding direction limiting base 8, and a support anchor bolt 9.

[0029] The upper steel plate 1 is located at the top of the support. Anchor bolt holes are provided at the four corners of the upper steel plate 1. Anchor bolts 9 pass through these holes and are connected to the upper beam. Pre-reserved limiting bolt holes 3 are provided around the upper steel plate 1. A stainless steel plate 4 and a quick-adjustable sliding direction limiting block 2 are provided at the bottom of the upper steel plate 1. The stainless steel plate 4 is closely attached to the upper steel plate 1. The quick-adjustable sliding direction limiting block 2 is set on the lower two sides or around the upper steel plate 1 according to the factory requirements of the support. The reserved limiting bolt holes 3 of the support without quick-adjustable sliding direction limiting blocks 2 are filled with filler bolts.

[0030] The stainless steel plate 4 is arranged on the lower part of the upper steel plate 1 of the support, closely adheres to the lower part of the upper steel plate 1 of the support, and is provided with two reserved limiting bolt holes around the stainless steel plate 4, which correspond to the reserved limiting bolt holes 3 of the upper steel plate 1 of the support. The lower part of the stainless steel plate 4 is connected with the fast-adjusting sliding direction limiting block 2 according to the factory delivery requirements of the support. The limiting bolt 10 of the limiting block 2 penetrates the reserved limiting bolt hole 3 on the stainless steel plate and enters the upper steel plate 1 of the support to be connected with the upper steel plate 1 of the support, and the connection between the stainless steel plate 4 and the upper steel plate 1 of the support is reinforced, so that they are closely adhered. The remaining reserved limiting bolt holes 3 which are not provided with the fast-adjusting sliding direction limiting block 2 are filled with filling bolts, and the top of the bolt is flush with the exposed surface of the stainless steel plate.

[0031] The fast-adjusting sliding direction limiting block 2 is arranged on the lower part of the upper steel plate 1 of the support and the stainless steel plate 4. The limiting block 2 is internally provided with a bolt hole and a limiting bolt 10. The side surface of the limiting block 2 is provided with a narrow edge stainless steel plate 11 opposite to the fast-adjusting sliding direction limiting base 8. The narrow edge stainless steel plate 11 is arranged on both sides or around the upper steel plate 1 of the support according to the factory delivery requirements of the support, and is connected with the upper steel plate of the support through a bolt. The limiting block 2 cooperates with the lower sliding direction limiting base 8 to limit the sliding direction of the support.

[0032] The intermediate lining plate 6 is arranged on the lower part of the upper steel plate 1 of the support and the stainless steel plate 4, and the upper part of the fast-adjusting sliding direction limiting base 8. A layer of high molecular weight polyethylene flat sliding plate 5 is arranged between the intermediate lining plate 6 and the stainless steel plate 4. For the ball-type sliding direction adjustable support, a layer of high molecular weight polyethylene spherical sliding plate 7 is arranged between the lower part of the intermediate lining plate 6 and the fast-adjusting sliding direction limiting base 8. For the basin-type sliding direction adjustable support, a layer of rubber pad 15 is arranged between the lower part of the intermediate lining plate 6 and the fast-adjusting sliding direction limiting base 8.

[0033] The fast-adjusting sliding direction limiting base 8 is located at the bottom of the support. The limiting base 8 is provided with support anchoring bolt holes at four corners. The anchoring bolt 9 penetrates the holes and is connected with the lower pier support cushion stone. The middle part of the limiting base 8 is a recess 14 for bearing the intermediate lining plate 6. The middle part is provided with four square protrusions 13 in four directions, forming a cross-shaped protruding structure. An sf-1 three-layer composite plate 12 is reserved on the outer vertical surface of each protruding structure, which is used to contact the narrow edge stainless steel plate 11 arranged on the side surface of the limiting block 2. The square protrusions cooperate with the limiting block 2 on the upper steel plate 1 of the support to limit the sliding direction of the support, so that the support can only slide in the direction where the limiting block is not arranged.

[0034] The adjustable sliding direction support is divided into four types according to the sliding direction of the support, i.e. longitudinal, transverse, bidirectional and fixed. The longitudinal support is provided with a limiting stopper on both sides of the transverse bridge direction when leaving the factory, the transverse support is provided with a limiting stopper on the longitudinal bridge direction when leaving the factory, the bidirectional support is not provided with a limiting stopper on the longitudinal and transverse directions when leaving the factory, and the fixed support is provided with a limiting stopper on the longitudinal and transverse directions when leaving the factory. When installing the support, the construction unit installs the corresponding support according to the sliding direction set by the design unit at the support position of the bridge.

[0035] For the adjustable sliding direction support, when the engineering project finds that the sliding direction of the support installed on the engineering site is inconsistent with the sliding direction designed by the design unit, for example, the transverse sliding support is installed as a longitudinal sliding support, and the longitudinal sliding support is limited in displacement in the transverse bridge direction and slides in the longitudinal bridge direction. At this time, only the limiting bolt 10 inside the limiting stopper 2 of the longitudinal sliding support is sequentially rotated out from the upper steel plate with a wrench, and the sliding limitation of this side is released. After the limiting stoppers on both sides are removed, the transverse bridge direction limitation is released. At this time, the filling bolt in the limiting bolt hole in the longitudinal bridge direction is taken out and filled into the limiting bolt hole in the transverse bridge direction, and the limiting steel plate removed before is installed in the longitudinal bridge direction through the limiting bolt. At this time, the sliding direction of the support is adjusted from longitudinal sliding to transverse sliding, and the support is changed from a longitudinal support to a transverse support. The adjustment of the sliding direction of the remaining supports is similar, and only the position and number of the quick adjustment type sliding direction limiting stopper need to be changed or increased or decreased to complete the adjustment of the sliding direction of the support.

[0036] The adjustment process of the adjustable sliding direction support does not need to perform bridge jacking operation, and high temperature and open fire will not occur. The adjustment process is clear, the required time for adjustment is short, the adjustment of the sliding direction of the support can be quickly completed, the adjustment operation is simple, and the structure after adjustment is reliable and complete in function. The successful development of the adjustable sliding direction support effectively solves the problem that the support is difficult to adjust after the sliding direction of the support is installed incorrectly in the engineering project.

[0037] The above only describes the preferred embodiments of the present application and is not used to limit the present application. For those skilled in the art, the present application can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
