Description

Technical Field

[0001] The utility model relates to the technical field of prefabricated steel molds for bridges, in particular to a prefabricated bridge deck steel mold structure for bridges. Background Art

[0002] With the rapid development of my country's economy, my country's bridge construction has also developed rapidly. In the process of bridge construction, prefabrication and assembly construction technology can significantly shorten the construction period and reduce the time of construction occupying the road. At the same time, it has the advantages of high construction quality, low safety risks and environmental protection. Therefore, prefabrication and assembly construction technology has been widely used in municipal bridge construction.

[0003] In the actual construction process of the prior art, there is such a problem: after the prefabricated bridge deck is completed, the disassembly of the steel formwork of the prefabricated bridge deck is very cumbersome, requires a lot of manpower and material resources, and has low work efficiency. Summary of the invention

[0004] In view of this, the purpose of the utility model is to provide a prefabricated bridge deck steel mold structure that can be easily disassembled and assembled.

[0005] The utility model is implemented by the following method: a prefabricated bridge deck steel mold structure, including a mold with an open upper surface, a side wall groove reserved at the left end of the mold, a mortar layer laid on the bottom surface of the mold, embedded sleeves are arranged at the left and right ends of the mortar layer, support plates on the front and rear sides of the mold are hinged, templates are arranged at the left and right ends of the upper end of the mold, a casting groove is formed between the template and the mortar layer, and grouting holes are arranged between the templates at the left and right ends.

[0006] Furthermore, a water hole is provided in the grouting hole.

[0007] The beneficial effects of the utility model are as follows: the utility model adds side wall grooves, templates and embedded sleeves to the device, which can facilitate space reservation to achieve the space required for demolding. Compared with cast-in-place bridge deck construction, it can ensure that the linear shape of the auxiliary facilities on the entire bridge is consistent and the appearance is beautiful. The utility model has a simple structure and is easy to operate, can effectively save manpower and material resources, and improve work efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0008] Figure 1 It is a structural schematic diagram of the utility model.

[0009] Figure 2 It is a schematic diagram of the internal structure of the utility model. DETAILED DESCRIPTION

[0010] The utility model is further described below in conjunction with the accompanying drawings.

[0011] See also Figure 1 and Figure 2 As shown, the utility model provides an embodiment: a prefabricated bridge deck steel mold structure, comprising a mold 1 with an open upper surface, a side wall groove 2 reserved at the left end of the mold 1, a mortar layer 3 laid on the bottom surface of the mold 1, and embedded sleeves 4 are arranged at the left and right ends of the mortar layer 3, and the support plates on the front and rear sides of the mold 1 are hinged, and templates 5 are arranged at the left and right ends of the upper end of the mold 1, and a casting groove 6 is formed between the template 5 and the mortar layer 3, and grouting holes 7 are arranged between the templates 5 at the left and right ends. Through the grouting holes 7, the casting groove 6 can be poured with concrete slurry to form a prefabricated bridge deck, and then the side wall groove 2 is used to facilitate the formation of the side wall after the bridge deck is formed. It is composed of four side molds and five bottom molds. The long side direction of the side mold can be opened and closed by means of a hinged setting, and the short side direction is fixed by using a movable bolt after being positioned with the long side mold by a positioning pin. The two end parts of the bottom formwork are fixed on the base bracket, and then the middle bottom formwork inside is laterally locked and clamped with the long side formwork by movable bolts to clamp the end bottom formwork. The middle section bottom formwork is composed of three parts. The middle bottom formwork is fixedly welded to the base. The bottom formworks on both sides are connected by hinge ears, and the size is controlled by the adjusting screw on the base. When demolding, the screw can be rotated to make the lateral surfaces of the bottom formworks on both sides away from the concrete surface to achieve the space required for demolding, which is convenient for demolding.

[0012] The hinge arrangement in the present invention is an existing hinge arrangement, which can be clearly understood by those skilled in the art and will not be described in detail here.

[0013] Please continue reading Figure 2 As shown, in one embodiment of the utility model, a water hole is provided in the grouting hole 7. After pouring, the water on the upper surface of the concrete can be discharged through the water hole to facilitate solidification.

[0014] The above description is only a preferred embodiment of the present invention. All equivalent changes and modifications made according to the scope of the patent application of the present invention should fall within the scope of the present invention.
