Description

Technical Field

[0001] This utility model relates to the field of bridge construction, and in particular to the field of bridge beam and slab bearing pad construction technology, specifically referring to an adjustable bearing pad template with mortar surface leveling. Background Technology

[0002] Bridge girder bearings are the most stress-concentrated and critical components in the entire road and bridge engineering project. The construction process and quality of the bearing pad directly affect the stress and service life of the rubber bearings, and have a direct impact on the overall bridge and engineering construction costs and subsequent maintenance. Under vehicle dynamic loads, if the top surface of the bearing pad is uneven, uneven stress will occur on the rubber bearings and bearing pads, easily leading to severe local deformation of the rubber bearings and bearing pads, significantly shortening the overall service life of the bridge bearing pads, and increasing the costs of daily maintenance and replacement of rubber bearings. Therefore, the construction quality of the bearings is particularly important.

[0003] Traditional bearing pad formwork often uses wooden boards or bamboo plywood, which have poor rigidity and limited functionality. This results in poor overall quality of the completed bearing pads, leading to significant differences in elevation between the four corners and unevenness on the top surface. Consequently, the bearing surface of the rubber bearing cannot fully rest on the bearing pad, failing to fully utilize its function. This can easily cause uneven pressure, uneven stress, and localized edge voids, thus shortening the service life of the rubber bearing and failing to meet bridge design and specification requirements. Utility Model Content

[0004] The main purpose of this utility model is to overcome the shortcomings of the prior art and provide an adjustable support pad stone template with mortar surface leveling.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An adjustable mortar-surface leveling support pad formwork, comprising:

[0030] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0031] like Figure 1 An adjustable support pad stone formwork with mortar surface leveling is shown, comprising:

[0032] Four steel templates 1, each steel template 1 includes a channel steel body 11 and an insertion part 12 located at one end of the channel steel body 11. The vertical surface of the insertion part 12 is provided with a through hole 121 suitable for the channel steel body 11 to pass through. Adjacent steel templates 1 are connected by the channel steel body 11 of one steel template 1 passing through the through hole 121 of the insertion part 12 of another steel template 1. The four steel templates 1 are connected to form a square frame structure with adjustable size.

[0033] Four horizontal detection devices 2 are respectively installed on the channel steel body 11 of the four steel templates 1.

[0034] Specifically, the width of the lower end face of the channel steel body 11 and the insertion part 12 is greater than the width of the upper end face.

[0035] Specifically, at least one first threaded hole or first nut 14 is provided on the lower end face of the insertion part 12. Each first threaded hole or first nut 14 is equipped with an adjusting rod 15 for adjusting flatness. A handle 151 is provided on the top of the adjusting rod 15. By rotating the handle 151, the adjusting rod 15 is rotated, which in turn causes the first threaded hole or first nut 14 to move up and down, thereby adjusting the height of the four corners of the square frame structure and controlling the flatness of the four corners of the support pad stone to the allowable range of the specification.

[0036] Specifically, each insertion part 12 has two first threaded holes or first nuts 14, which are arranged side by side on the lower end face of the insertion part 12. Having two first threaded holes or first nuts 14 can, to a certain extent, ensure the balance when adjusting the steel template.

[0037] Specifically, each plug-in part 12 has at least one second threaded hole on its upper end face, and a fixing bolt 13 is installed in the second threaded hole.

[0038] Specifically, each insertion part 12 has two fixing bolts 13 arranged along its length. The upper end face of the insertion part 12 is stepped, and the two fixing bolts 13 are threaded together and pass through a stepped surface. The outer fixing bolt 13 abuts against the lower end face of the channel steel body 11, and the inner fixing bolt 13 abuts against the upper end face of the channel steel body 11, thus tightening and fixing the channel steel body 11. The stepped structure of the insertion part 12 also prevents the channel steel body 11 from shifting laterally relative to the insertion part during the pouring of the foundation stone, ensuring the construction quality of the foundation stone.

[0039] Specifically, the leveling device 2 includes a base 21, a magnet 22, and a spirit level 23. The spirit level 23 is cylindrical and is located on the upper surface of the base 21. The magnet 22 is parallel to the spirit level 23 and is located on the lower surface of the base 21. The leveling device 2 is fixed to the channel steel body 11 by the magnet 22. The spirit level 23 is parallel to the steel template 1. By observing the position of the bubble in the spirit level 23, the flatness of the steel template 1 can be determined. By rotating the adjusting rod 15, the flatness of the steel template 1 can be adjusted so that the bubbles in the four spirit levels 23 of the leveling device 2 are all in a centered state.

[0040] Specifically, it also includes a mortar leveling device 3, which includes a finishing panel 31 and a handrail 32. The handrail 32 is fixedly connected to the finishing panel 31 by fixing nails 33. The length of the finishing panel 31 is greater than the span between two opposite steel templates 1 in the square frame structure.

[0041] The specific working state of the adjustable support pad stone formwork with mortar surface leveling provided by this utility model is as follows:

[0042] Before construction, the steel formwork 1 is connected by passing the channel steel body 11 of one steel formwork 1 through the through hole 121 of the insertion part 12 of another steel formwork 1. The four connected steel formwork 1 form an adjustable square frame structure. The size of the square frame structure formed by the four connected steel formwork 1 is adjusted according to the size of the support pad stone to be constructed. After adjustment, the channel steel body 1 is pressed and fixed by the fixing bolts 13 on the upper end face of the insertion part 12. The installed square frame structure of steel formwork 1 is placed at the construction position of the pad stone. The level detection device 2 is fixed and installed at an appropriate position on the channel steel body 11 by the magnet 22. The adjusting rod 15 is installed into the first threaded hole or the first nut 14. The handle 151 is turned according to the status of the level detection device to adjust the flatness of the mold until the bubbles in the four level bubbles 23 are in the center position, thus completing the flatness adjustment of the four corners of the support pad stone.

[0043] During construction, the adjusted template is used for pouring. After pouring, the mortar leveling device 3 is used to finish the top of the pad stone.

[0044] After construction is completed, remove the leveling device 2 and wait for the support pad to be formed. After the pad is formed, loosen the fixing bolts 13 on the upper end face of the insertion part 12 of the steel template 1, and pull out the channel steel body 11 from the through hole 121 of the insertion part 12. Disassemble and store the square frame structure formed by the steel template 11.

[0045] Of course, the above description is only for describing specific implementation methods and is not intended to limit the present utility model. The present utility model is not limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present utility model should also fall within the protection scope of the present utility model.
