[0023] Embodiment 1

[0024] As Figure 1 shown:

[0025] A temporary bridge structure for bridge construction includes two groups of support columns 1.

[0026] In this embodiment: The existing device {Publication (Announcement) Number}: CN215052221U discloses a temporary guardrail device for bridge construction. Regarding this existing main body, this application makes further improvements. For details, refer to the publicly disclosed technology below; to solve the technical problems existing in this existing technology, as disclosed in the background technology above, "When the above design is in use, although it can conveniently and quickly install and fix the installation column and the counterweight base, when installing the guardrail, multiple sets of self-locking hooks and hanging rings need to be operated for connection, resulting in low installation efficiency. Moreover, the width of the bridge and the length of the guardrail are fixed, which easily causes gaps between the bridge and the guardrail, affecting the temporary protection of the bridge construction by the guardrail and reducing the use effect of the device." In combination, this problem is obviously a real and relatively difficult problem to solve. In view of this, to solve this technical problem, a connection protection component 2 is added to this application document.

[0027] Furthermore:

[0028] As Figures 1-5 shown:

[0029] A connection protection component 2 is installed between two groups of support columns 1. The connection protection component 2 includes steel cables 201 arranged symmetrically between the two groups of support columns 1, pressing plates 205 arranged on the adjacent sides of the two groups of support columns 1, and adjusting screws 206 rotatably connected to the surfaces of the pressing plates 205 through bearings. The adjusting screws 206 are threadedly connected to the support columns 1. A plurality of groups of equally spaced baffle plates 202 are arranged between the two groups of steel cables 201. A pair of symmetrically arranged mounting seats 211 are fixed on one side of the baffle plate 202. A clamping plate 213 is slidably connected inside the mounting seat 211. A pair of symmetrically arranged springs 212 are fixed between the clamping plate 213 and the mounting seat 211. A sliding groove adapted to the clamping plate 213 is formed on the surface of the mounting seat 211. The clamping plate 213 and the mounting seat 211 are slidably connected through this sliding groove. A pair of symmetrically arranged limiting rods 207 are fixed on the surface of the pressing plate 205. Limiting holes adapted to the limiting rods 207 are formed on the surface of the support column 1. The limiting rods 207 and the support column 1 are slidably connected through these limiting holes. A pair of symmetrically arranged rectangular grooves are formed on the adjacent sides of the two groups of support columns 1, and a U-shaped seat 203 is arranged in the rectangular groove. A roller 204 is rotatably connected to the inside of the U-shaped seat 203 through a rotating shaft. The U-shaped seat 203 is fixed to the support column 1 through bolts. The two ends of the steel cable 201 are respectively wound around the surfaces of the two groups of rollers 204.

[0030] In this embodiment: For the temporary bridge structure used in bridge construction, during use, first, fix the two support columns 1 at the front end and the end of the bridge construction area respectively. Subsequently, pass both ends of the steel cable 201 through the rollers 204. Through the settings of the U-shaped seat 203 and the rollers 204, the steel cable 201 can be positioned, so that the two steel cables 201 are in a parallel state. At the same time, one end of the steel cable 201 passes through between the roller 204 and the U-shaped seat 203, and at the same time passes through between the pressing plate 205 and the support column 1. Then rotate the adjusting screw 206 on the support column 1 to drive the pressing plate 205 to move. By moving the pressing plate 205, the steel cable 201 is squeezed and fixed. While the pressing plate 205 moves, it drives the limiting rod 207 to move. Through the setting of the limiting rod 207, the pressing plate 205 is limited, making the movement of the pressing plate 205 more stable. Subsequently, pull the other ends of the two steel cables 201. At the same time, the steel cable 201 slides on the roller 204, so that while playing a role in limiting and positioning, the friction force in contact with the steel cable 201 can be reduced, and the pulling effect on the steel cable 201 can be improved. By pulling the steel cable 201, the two steel cables 201 are in a completely taut state. Then rotate the other adjusting screw 206 to drive the pressing plate 205 to squeeze and fix the steel cable 201. Subsequently, press the two clamping plates 213 so that the clamping plates 213 move into the mounting seat 211 and compress the spring 212. Then fit the shielding plate 202 with the two steel cables 201. At the same time, the two mounting seats 211 are located outside the two steel cables 201. Then release the clamping plates 213. At this time, the spring 212 rebounds and drives the clamping plates 213 to move. The spring 212 drives the clamping plates 213 to squeeze and fix the steel cable 201, thus completing the position locking of the shielding plate 202. Through the above operations, the bridge guardrail can be installed quickly, the installation efficiency can be improved, and the labor intensity of the staff can be reduced. Moreover, this installation method can adapt to bridges of different widths for shielding and protection, and there will be no gap between the bridge and the guardrail, improving the temporary protection effect and having a better use effect.

[0031] Furthermore;

[0032] In an alternative embodiment, symmetrically arranged teeth 208 are fixed on one side of the surface of the pressing plate 205 close to the support column 1.

[0033] In this embodiment: As the pressing plate 205 moves, it drives the teeth 208 to move. Through the contact and extrusion between the teeth 208 and the steel cable 201, through the setting of the teeth 208, the friction force can be increased, and the squeezing and fixing effect on the steel cable 201 can be improved.

[0034] Furthermore;

[0035] In an alternative embodiment, a silica gel pad 214 is fixed on the surface of the clamping plate 213.

[0036] In this embodiment: through the silica gel pad 214 on the clamping plate 213, the friction between the clamping plate 213 and the steel cable 201 can be increased, and the fixing effect on the shielding plate 202 can be improved.

[0037] Furthermore;

[0038] In an alternative embodiment, mounting holes are formed on the surface of a group of support columns 1, and a laser ray instrument 209 is arranged in the mounting holes. The laser ray instrument 209 is fixedly connected to the support column 1, and positioning grooves 210 corresponding to the laser ray instrument 209 are formed on the surface of the other group of support columns 1.

[0039] In this embodiment: during the fixing process, the laser ray instrument 209 is turned on to emit a light beam. When the laser ray is projected onto the surface of the other support column 1 and corresponds to the positioning groove 210 formed on the support column 1, the two groups of support columns 1 are parallel to each other at this time, thereby improving the installation efficiency of the support column 1 and achieving a better use effect.

[0040] It should be noted that: the laser ray instrument 209 is a highly concentrated and highly directional light beam, which can maintain a very straight line over a long distance. Utilizing this characteristic, we can project the laser ray onto the positioning groove 210. If the position of the emitted light spot is the same as that of the light spot in the positioning groove 210, then it can be determined that the two support columns 1 are parallel and corresponding.

[0041] Working principle and usage process of the utility model: For the temporary bridge structure used in bridge construction, during use, first, fix the two support columns 1 at the front end and the end of the bridge construction area respectively. During the fixing process, turn on the laser ray instrument 209 so that the laser ray instrument 209 emits a light beam. When the laser ray projects onto the surface of the other support column 1 and corresponds to the positioning groove 210 opened on the support column 1, at this time, the two support columns 1 are parallel to each other correspondingly, thereby improving the installation efficiency of the support column 1 and achieving a better usage effect. Subsequently, pass the two ends of the steel cable 201 through the rollers 204. Through the settings of the U-shaped seat 203 and the rollers 204, the steel cable 201 can be positioned, making the two steel cables 201 in a parallel state. At the same time, one end of the steel cable 201 passes through between the roller 204 and the U-shaped seat 203 and also passes through between the pressing plate 205 and the support column 1. Then, rotate the adjusting screw 206 on the support column 1 to drive the pressing plate 205 to move. Through the movement of the pressing plate 205, the steel cable 201 is squeezed and fixed. While the pressing plate 205 moves, it drives the limiting rod 207 to move. Through the setting of the limiting rod 207, the pressing plate 205 is limited, making the movement of the pressing plate 205 more stable. At the same time, as the pressing plate 205 moves, it drives the tooth 208 to move. Through the contact and extrusion between the tooth 208 and the steel cable 201, through the setting of the tooth 208, the friction force can be increased, improving the squeezing and fixing effect on the steel cable 201. Subsequently, pull the other ends of the two steel cables 201. At the same time, the steel cable 201 slides on the roller 204, which can not only play a role in limiting and positioning but also reduce the friction force in contact with the steel cable 201, improving the pulling effect on the steel cable 201. Through the pulling of the steel cable 201, the two steel cables 201 are in a completely taut state. Then, rotate the other adjusting screw 206 to drive the pressing plate 205 to squeeze and fix the steel cable 201. Subsequently, press the two clamping plates 213 so that the clamping plates 213 move into the mounting seat 211 and compress the spring 212. Then, fit the shielding plate 202 with the two steel cables 201. At the same time, the two mounting seats 211 are located outside the two steel cables 201. Then, release the clamping plates 213. At this time, the spring 212 rebounds and drives the clamping plates 213 to move. The spring 212 drives the clamping plates 213 to squeeze and fix the steel cable 201, thereby completing the position locking of the shielding plate 202. Through the silica gel pad 214 on the clamping plate 213, the friction force between the clamping plate 213 and the steel cable 201 can be increased, improving the fixing effect on the shielding plate 202. Through the above operations, the bridge guardrail can be installed quickly, improving the installation efficiency, reducing the labor intensity of the staff at the same time. Moreover, this installation method can adapt to bridges of different widths for shielding and protection, preventing gaps between the bridge and the guardrail, and improving the temporary protection effect with a better usage effect.

[0042] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not intended 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 described in the foregoing embodiments or perform equivalent replacements for some of the technical features.
