Technical Field

[0001] The utility model relates to the technical field of road and bridge construction, in particular to a template splicing structure for road and bridge construction. Background Art

[0002] When pouring concrete roads during road and bridge construction, channel steels are often laid on both sides of the road as concrete road pouring templates. The end faces of two adjacent channel steels are aligned and fit together, and then the insert rod is passed through the circular sleeve fixed on the side of the template and inserted into the ground to fix the template.

[0003] When using common formwork for road and bridge construction, the end faces of two adjacent formworks are aligned and fit together, and then the formworks are positioned using inserted rods. However, when concrete is poured on the roadbed and during the solidification process, the formworks are subject to the lateral pressure of the concrete, and the joints of the two adjacent formworks are prone to increased gaps or misalignment of the two adjacent formworks, thereby affecting the flatness of the side of the concrete road. Therefore, the present application provides a formwork splicing structure for road and bridge construction to meet the needs. Summary of the Invention

[0004] The technical problem to be solved by the utility model is to provide a template splicing structure for road and bridge construction to solve the technical problem that under the lateral pressure of concrete, the gap between the splicing points of two adjacent templates is easily enlarged or the two adjacent templates are misaligned, thereby affecting the flatness of the side of the concrete road.

[0005] In order to solve the above technical problems, the present invention provides the following technical solutions:

[0006] A template splicing structure for road and bridge construction, comprising a first template and a second template, wherein opposite ends of the first template and the second template are affixed to each other, and further comprising:

[0007] The splicing assembly includes a slot opened at one end of the template and an insert block fixed at the second end of the template, the insert block is inserted into the slot and fits with the inner wall of the slot, a square sleeve is fixed on the side of the inner wall of the second template, the insert block is fixedly connected to the side of the square sleeve, a connecting block is fixed to the inner wall of the first template, an insert strip is fixed on the side of the connecting block close to the square sleeve, the insert strip is inserted into the square sleeve, a through slot is opened on the top of the insert strip, an L-shaped pin is movably passed through the top of the second template, the L-shaped pin movably passes through the square sleeve and is inserted into the interior of the through slot, an inclined extrusion surface is provided on the side of the L-shaped pin, and a curved surface one is provided on the side of the inner wall of the through slot, and the extrusion surface fits with the curved surface one.

[0008] Preferably, a guide sleeve is fixed to the top of the inner wall of the second template, and the inner wall of the guide sleeve is slidably connected to the side of the L-shaped pin.

[0009] Preferably, two support blocks are fixed to the top of the inner wall of the second template, and the guide sleeve is located between the two support blocks.

[0010] Preferably, a second curved surface is provided on a side of the L-shaped pin close to the second template.

[0011] Preferably, a wear-resistant block is fixed on the top of the second template, and the wear-resistant block is located below the second curved surface.

[0012] Preferably, a rib is fixed on the side of the inner wall of the second template, and the rib is fixed on the side of the square sleeve away from the connecting block.

[0013] Preferably, an inclined guiding surface is provided on a side of the L-shaped pin away from the first curved surface.

[0014] Preferably, a rounded chamfer is provided at the corner of the insert away from the second template.

[0015] Compared with the prior art, the present invention has at least the following beneficial effects:

[0016] In the above scheme, by setting up the splicing assembly, the splicing assembly is used to make the connection between template one and template two tighter and more reliable, which can prevent template one and template two from separating when subjected to lateral pressure from concrete, and at the same time prevent template one and template two from being misaligned, thereby ensuring the flatness of the side of the concrete road.

[0017] By setting the wear-resistant block and the support block, when it is necessary to separate template one and template two, a crowbar is inserted between the wear-resistant block and the curved surface two of the L-shaped pin, and then the L-shaped pin is pried with the crowbar. While the crowbar is against the wear-resistant block, the end of the crowbar drives the L-shaped pin to move upward. When the L-shaped pin is loose, the L-shaped pin can be pulled out of the through groove. After pulling it out, template one and template two can be separated. The wear-resistant block is used to prevent the crowbar from contacting the top of template one, to prevent the position of the crowbar corresponding to the top of template one from being worn after long-term use. At the same time, the support block is fixed below the position of the inner wall of template one corresponding to the position where the crowbar is against, to improve the structural strength of template one at the position where the crowbar is against, to prevent template one from deformation, and to increase the service life of template one.

Furthermore, the accompanying drawings are intended only to provide a more detailed description of the embodiments and are not intended to limit the present invention.

[0030] like Figure 1-Figure 7 As shown, an embodiment of the present invention provides a template splicing structure for road and bridge construction, including a template 1 and a template 2, wherein the opposite ends of the template 1 and the template 2 are affixed to each other, and further comprising:

[0031] Splicing component 3, splicing component 3 includes a slot 5 opened at the end of template 1 and an insert block 4 fixed at the end of template 2, the insert block 4 is inserted into the slot 5 and fits with the inner wall of the slot 5, the insert block 4 is inserted into the slot 5, used to prevent template 1 and template 2 from being misaligned in the vertical direction, a square sleeve 6 is fixed on the side of the inner wall of template 2, the square sleeve 6 does not contact the inner wall of template 1, the insert block 4 is fixedly connected to the side of the square sleeve 6, the inner wall of template 1 is fixed with a connecting block 8, the side of the connecting block 8 close to the square sleeve 6 is fixed with an insert strip 7, the insert strip 7 is inserted into the square sleeve 6, a through slot 10 is opened on the top of the insert strip 7, the top of template 2 movably penetrates an L-shaped pin 9, the L-shaped pin 9 movably penetrates the square sleeve 6 and is inserted into the inside of the through slot 10, the L-shaped pin 9 is provided with an inclined extrusion surface 13 on the side, and a curved surface 11 is provided on the side of the inner wall of the through groove 10. The extrusion surface 13 fits with the curved surface 11. The L-shaped pin 9 is passed through the template 2 2 and the square sleeve 6 and inserted into the through groove 10 of the insert 7. The top of the L-shaped pin 9 is hammered with a hammer to make the L-shaped pin 9 move downward. The extrusion surface 13 of the L-shaped pin 9 squeezes the curved surface 11 in the through groove 10, so that the insert 7 moves to the right along the inner wall of the square sleeve 6 and drives the template 1 to move to the right through the connecting block 8, so that the end faces of the template 1 and the template 2 2 fit closely, which can prevent the template 1 and the template 2 2 from separating when subjected to lateral pressure from the concrete, and prevent the template 1 and the template 2 2 from being misaligned, thereby ensuring the flatness of the side of the concrete road.

[0032] like Figure 2 and Figure 5 As shown, in this embodiment, a guide sleeve 18 is fixed to the top of the inner wall of the template 2, and the inner wall of the guide sleeve 18 is slidably connected to the side of the L-shaped pin 9. During the downward movement of the L-shaped pin 9, the guide sleeve 18 guides the movement of the L-shaped pin 9, making the vertical movement of the L-shaped pin 9 more stable and smooth.

[0033] like Figure 5 As shown, in this embodiment, two support blocks 15 are fixed to the top of the inner wall of the template 2, and the guide sleeve 18 is located between the two support blocks 15. When a crowbar is used to pry the L-shaped pin 9, the support block 15 is used to support the bottom of the position where the crowbar is against, thereby preventing the top of the template 2 2 from deformation.

[0034] like Figure 7 As shown, in this embodiment, a second curved surface 17 is provided on the side of the L-shaped pin 9 close to the second template 2. The design of the second curved surface 17 is used to improve the structural strength of the contact position between the L-shaped pin 9 and the crowbar, thereby effectively preventing the L-shaped pin 9 from deforming.

[0035] like Figure 1As shown, in this embodiment, a wear-resistant block 14 is fixed to the top of the template 2, and the wear-resistant block 14 is located below the curved surface 2 17. When a crowbar is used to pry up the L-shaped pin 9, the wear-resistant block 14 is used to prevent the crowbar from contacting the top of the template 2, thereby preventing the top of the template 2 from wearing.

[0036] like Figure 1 and Figure 2 As shown, in this embodiment, a rib 16 is fixed to the side of the inner wall of the template 2, and the rib 16 is fixed to the side of the square sleeve 6 away from the connecting block 8. The rib 16 is used to increase the contact area between the square sleeve 6 and the inner wall of the template 2, thereby improving the connection strength between the square sleeve 6 and the template 2, and thus improving the fixing stability of the square sleeve 6.

[0037] like Figure 7 As shown, in this embodiment, an inclined guide surface 12 is provided on the side of the L-shaped pin 9 away from the curved surface 11. Through the inclined guide surface 12, when the L-shaped pin 9 is inserted into the square sleeve 6, it is guided by the guide surface 12, thereby facilitating the insertion of the L-shaped pin 9 into the square sleeve 6.

[0038] like Figure 3 and Figure 4 As shown, in this embodiment, a circular chamfer is provided at the corner of the insert block 4 away from the template 2 2. The circular chamfer design enables the insert block 4 to be guided when inserted into the end slot 5 of the template 1, making it convenient for the insert block 4 to be inserted into the slot 5, thereby facilitating the splicing of template 1 and template 2 2.

[0039] Working principle: When splicing template 1 and template 2, insert the insert strip 7 in template 1 into the square sleeve 6 in template 2, and at the same time insert the insert block 4 of template 2 into the slot 5 of template 1. Then, pass the L-shaped pin 9 through template 2 and the square sleeve 6 and insert it into the through slot 10 of the insert strip 7. Use a hammer to hammer the top of the L-shaped pin 9 to make the L-shaped pin 9 move downward. During the downward movement of the L-shaped pin 9, the extrusion surface 13 of the L-shaped pin 9 squeezes the curved surface 11 in the through slot 10, making the insert strip 7 move to the right while driving template 1 through the connecting block 8. 1 moves to the right, so that the end faces of template 1 and template 2 are tightly fitted, and at the same time, the insert block 4 is tightly fitted with the inner wall of the slot 5, which can prevent template 1 and template 2 from separating when subjected to lateral pressure from concrete, and prevent template 1 and template 2 from being misaligned, thereby ensuring the flatness of the side of the concrete road. After template 1 and template 2 are spliced ​​together, the insert rod is passed through the circular sleeves on the sides of template 1 and template 2 and inserted into the ground to achieve the positioning of template 1 and template 2. After positioning, the road concrete can be poured;

[0040] After the concrete solidifies, formwork 1 and formwork 2 2 need to be removed from the side of the road. During disassembly, first pull the insertion rod out of the round sleeve, then use a crowbar to insert between the wear-resistant block 14 and the curved surface 2 17 of the L-shaped pin 9, and then use the crowbar to pry the L-shaped pin 9. While the crowbar is against the wear-resistant block 14, the end of the crowbar drives the L-shaped pin 9 to move upward, and pry up the L-shaped pin 9 so that the extrusion surface 13 of the L-shaped pin 9 is no longer in close contact with the curved surface 11 in the through groove 10. At this time, the L-shaped pin 9 can be pulled out of the through groove 10. After pulling it out, move formwork 1 to the left again, so that formwork 1 drives the insertion strip 7 to separate from the square sleeve 6 through the connecting block 8, and at the same time, the insertion block 4 is separated from the slot 5. After separation, the separation of formwork 1 and formwork 2 2 can be achieved.

To provide a thorough understanding of the present invention, specific details are described in detail in the preferred embodiments of the present invention above, but those skilled in the art can fully understand the present invention without these detailed descriptions.

[0042] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
