Description

Technical Field

[0001] The utility model relates to the technical field of bridge construction, in particular to a clamping device that can be used for positioning a cap template of a conventional railway. Background Art

[0002] At present, the railway cap is a kind of substructure of the bridge. The common construction method is mainly the steel formwork method. The steel formwork needs to have sufficient strength and rigidity. The accurate positioning measures of the formwork are very important for the stability of the formwork structure. The steel formwork method means that when the cap is constructed, after each formwork is assembled, the formwork is fastened and accurately positioned by using connectors and fixtures to withstand the force generated during concrete pouring. It has the function of preventing the cap formwork from expanding outward, tilting inward and deforming when pouring concrete, and plays a good role in positioning the formwork. This method can avoid the use of tie rods, eliminate the shortcomings of tie rods that are easy to deform and have limited turnover times. This method can be used for all rectangular cap construction. The common cap formwork reinforcement adopts the method of setting tie rods to pull inward, and then using short square wooden supports and wooden wedges to support the formwork on the outside of the cap formwork. The short wooden supports act on the soil around the foundation pit, and the stability of the surrounding soil must be ensured. If the surrounding soil collapses, there is a certain risk. During the rainy season, the influence of the soil around the foundation pit of the pedestal is further increased. The traditional method is not conducive to ensuring the construction period requirements and is subject to many constraints. Therefore, there is an urgent need for a positioning fixture device that can be used for the pedestal template of conventional railways, which is easy to install and disassemble, has good stability, and reduces dependence on the surrounding soil. Utility Model Content

[0003] The purpose of the utility model is to overcome the deficiencies in the above-mentioned prior art and to provide a positioning fixture device which can be used for conventional railway foundation templates, has convenient installation and disassembly, good stability, and reduces dependence on surrounding soil.

[0004] In order to achieve the above object, the utility model is implemented through the following technical solutions:

[0005] A clamping device that can be used for positioning a cap template of a conventional railway, wherein the cap templates are fixedly connected with connecting pieces, wherein two cap templates along the length direction are connected by a middle connecting piece, and the four corners of the cap template are connected by inclined connecting pieces, and the ends of each connecting piece are provided with connecting plates, and the connecting plates are symmetrically provided with connecting holes that match the edges of the cap templates.

[0006] Furthermore, the connecting parts are all formed by symmetrically fixedly connecting the webs of two channel steels.

[0007] Compared with the prior art, the utility model has the following beneficial effects:

[0008] The utility model discloses that the pedestal formwork is easy to install and disassemble and has good structural stability. The pedestal formworks are connected to each other by connecting parts and can be fastened and constrained to each other, effectively preventing the pedestal formworks from expanding outward, tilting inward and deforming when pouring concrete. The dependence on the surrounding soil is greatly reduced and the pedestal formworks will not be affected by the weather. The construction period is short and it is convenient for workers to operate.

[0015] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0016] like Figures 1 to 4 As shown, a clamping device that can be used for positioning the foundation template of a conventional railway, wherein the foundation templates 4 are fixedly connected with connecting parts, wherein two foundation templates 4 along the length direction are connected by a middle connecting part 1, and the four corners of the foundation template 4 are connected by inclined connecting parts 2, and a connecting plate 3 is provided at the end of each connecting part, and connecting holes that match the edges of the foundation template 4 are symmetrically provided on the connecting plate 3.

[0017] The connecting members 3 are all formed by symmetrically fixedly connecting the webs of two channel steels. The connecting members formed by the double channel steels have stronger rigidity and better stability.

[0018] The construction steps of the utility model are as follows: first, hoist the cap template 4, install the corner template at a suitable position, and after the two cap templates 4 at the corners are installed, use the inclined connector 2 to temporarily fix the two adjacent cap templates 4 at the corners, and then install the remaining cap templates 4. Then install the middle connector 1 and the remaining inclined connectors 2 in sequence, and after all the cap templates 4 are assembled, connect the connectors firmly through the connecting plate 3 to form a stable whole. After all the installations are completed, the cap concrete construction can be carried out, and the springboard can also be fully laid on the top of the cap to form a stable construction platform with sufficient bearing capacity for the next construction process.

[0019] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
