Description

Technical Field

[0001] This utility model relates to the field of road concrete pouring, specifically to a road concrete formwork installation structure. Background Technology

[0002] Concrete pavement formwork is a temporary mold used in concrete pavement construction to determine the shape, size, and boundaries of the pavement, ensuring uniform concrete thickness and neat edges. During installation, to ensure the stability and accuracy of the formwork, a bolted assembly structure is typically used. However, when using bolted assemblies, the bolts may gradually loosen under the impact and other external forces during concrete pouring. Once loosened, the formwork's position will shift, causing the pavement's dimensions and shape to deviate from design requirements. Furthermore, the sealing performance of a loosened formwork will decrease, potentially leading to grout leakage and affecting the quality of the concrete pavement. Moreover, when the formwork area is large and a large number of bolts need to be installed, the construction period will be significantly extended.

[0003] Meanwhile, each existing road concrete formwork has at least five tripod structures installed on it. Multiple tripods need to be rotated one by one to make them perpendicular to the formwork before they are fixed to the ground by inserting posts. Since there are many tripods, the process of driving in the posts for each tripod is relatively time-consuming, especially when a large number of tripods need to be fixed. Driving in the posts for each tripod one by one will also slow down the construction speed. Utility Model Content

[0004] This invention addresses the problem that existing road concrete formwork uses a bolt assembly structure, which not only leads to bolt loosening when installing a large number of formworks but also increases the construction period. Therefore, this invention provides a road concrete formwork installation structure.

[0005] The technical solution of this utility model is:

[0006] A road concrete formwork installation structure comprises a formwork unit, wherein the left end of the formwork unit has an insertion hole and the right end of the formwork unit is connected to an insertion post, and the insertion post is inserted into the insertion hole of the adjacent formwork unit. A set of formwork units are connected end to end to form a road concrete formwork. Adjacent formwork units of the road concrete formwork installation structure are connected by a clamping mechanism. The clamping mechanism and the insertion post are used in conjunction, and the clamping mechanism and the insertion post are connected by an insertion clamping type.

[0007] The clamping mechanism includes a clamping plate, a handle, and a locking hole;

[0008] The top and bottom of the clamping plate are fixedly connected to the handle. Two locking holes with the same structure are opened on the longitudinal center line of the clamping mechanism. The locking holes are inserted into the insert post. The top hole surface of the locking hole is a planar structure, and the bottom hole surface of the locking hole is an arc-shaped structure, and the arc-shaped structure is the same as the arc-shaped surface of the insert post.

[0009] The insert post has a slot near the middle position that matches the clamping mechanism. The thickness of the clamping plate of the clamping mechanism is less than the width of the slot. The insert post passes through the insertion hole of the adjacent template unit, and the locking hole of the clamping mechanism is inserted into the slot. The two adjacent template units are locked together by the clamping mechanism.

[0010] Furthermore, the rear of the template unit is connected to a left support rotating rod and a right support rotating rod. The left support rotating rod and the right support rotating rod are movably connected to a fixed shaft at the rear of the template unit, and the left support rotating rod is positioned above the right support rotating rod.

[0011] Furthermore, the left support rotating rod includes a left rotating rod, a left insert, a left sleeve, and a left support;

[0012] One end of the left rotating rod is fixedly connected to the left insert, and the other end is fixedly connected to the left sleeve. The left sleeve is fitted onto the fixed shaft on the left side of the template unit, allowing the left sleeve to rotate on the fixed shaft. The left support supports the bottom of the left sleeve, and the left support is fixedly connected to the fixed shaft on the left side of the template unit.

[0013] Furthermore, the right support rotating rod includes a right rotating rod, a right insert, a right sleeve, and a right support;

[0014] One end of the right rotating rod is fixedly connected to the right insert cylinder, and the other end is fixedly connected to the right sleeve. The right sleeve is fitted onto the fixed shaft on the right side of the template unit, allowing the right sleeve to rotate on the fixed shaft. The right support supports the bottom of the right sleeve, and the right support is fixedly connected to the fixed shaft on the right side of the template unit.

[0015] Furthermore, the left insert of the left support rotating rod and the right insert of the right support rotating rod on the adjacent template unit are provided with insert fixing structures.

[0016] Furthermore, the insert fixing structure includes two fixing plugs, a crossbeam, a top plate, a triangular plate, and a baffle.

[0017] The top of the fixing plug is connected to the top plate, a triangular plate is installed between the top plate and the fixing plug, two adjacent fixing plugs are fixedly connected by a crossbeam, and the baffle is fixedly connected to the fixing plug.

[0018] Furthermore, fixing inserts are respectively inserted into the left cylinder of the left support rotating rod and the right cylinder of the right support rotating rod.

[0019] Furthermore, a set of longitudinal stiffeners are connected to the back of the template unit.

[0020] Compared with the prior art, the present invention has the following advantages:

[0021] This invention enables the rapid installation of two adjacent template units through a clamping mechanism and a slot on the insertion post, replacing the traditional bolt assembly connection structure. This prevents loosening between adjacent template units and eliminates the need for additional tools during installation, effectively saving installation time and significantly improving construction efficiency, especially in large-scale construction projects. Furthermore, after disassembly, both the template units and the clamping mechanism maintain good integrity, facilitating reuse and reducing material costs, thus aligning with economic and environmental protection principles.

[0022] This utility model replaces the traditional tripod structure. Each template unit is equipped with a left support rotating rod and a right support rotating rod. The left and right support rotating rods are used in conjunction with the plug-in fixing structure to fix the left and right support rotating rods, thereby improving construction efficiency.

[0041] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model, but are not intended to limit the scope of this utility model. Specific implementation method one:

[0043] Combination Figure 1 — Figure 11 This embodiment describes a road concrete formwork installation structure, which comprises a formwork unit 1. The left end of the formwork unit 1 has an insertion hole 11, and the right end of the formwork unit 1 is connected to an insertion post 12. The insertion post 12 is inserted into the insertion hole 11 of the adjacent formwork unit 1. A set of formwork units 1 are connected end to end to form a road concrete formwork. Two adjacent formwork units 1 of the road concrete formwork installation structure are connected by a clamping mechanism 2. The clamping mechanism 2 and the insertion post 12 are used in conjunction, and the clamping mechanism 2 and the insertion post 12 are connected by an insertion clamping type.

[0044] The clamping mechanism 2 includes a clamping plate 21, a handle 22 and a locking hole 23. The handle 22 facilitates the movement of the clamping plate 21, thereby removing the clamping plate 21 from the insert post 12.

[0045] The top and bottom of the clamping plate 21 are fixedly connected to the handle 22. Two locking holes 23 with the same structure are opened on the longitudinal center line of the clamping mechanism 2. The locking holes 23 are inserted into the insert post 12. The top hole surface of the locking hole 23 is a planar structure, and the bottom hole surface of the locking hole 23 is an arc-shaped structure, and the arc-shaped structure is the same as the arc-shaped surface of the insert post 12.

[0046] The insert post 12 has a slot 121 near the middle position that matches the clamping mechanism 2. The thickness of the clamping plate 21 of the clamping mechanism 2 is less than the width of the slot 121. The insert post 12 passes through the insertion hole 11 of the adjacent template unit 1. The locking hole 23 of the clamping mechanism 2 is inserted into the slot 121, and the two adjacent template units 1 are locked by the clamping mechanism 2.

[0047] When the insert post 12 of the template unit 1 is inserted into the insertion hole 11 of the adjacent template unit 1, the slot 121 on the insert post 12 extends out of one side of the template unit 1. Then, the locking hole 23 on the clamping mechanism 2 is inserted into the insert post 12. When one side of the clamping plate 21 is in contact with the side plate of the template unit 1, the clamping mechanism 2 is pressed vertically downward, so that the clamping 21 of the clamping mechanism 2 is inserted into the slot 121 of the insert post, thus limiting the clamping mechanism 2. At this time, the hole surface at the upper end of the locking hole 23 of the clamping mechanism 2 is in contact with the slot surface of the slot 121. The installation of two adjacent template units 1 is quickly completed through the clamping mechanism 2. Specific Implementation Method Two:

[0049] Combination Figure 2 — Figure 4 This embodiment describes a road concrete formwork installation structure. The rear of the formwork unit 1 is connected to a left support rotating rod 3 and a right support rotating rod 4. The left support rotating rod 3 and the right support rotating rod 4 are movably connected to a fixed shaft 5 at the rear of the formwork unit 1, and the left support rotating rod 3 is positioned above the right support rotating rod 4.

[0050] Each template unit 1 only requires a left support rotating rod 3 and a right support rotating rod 4, replacing the traditional triangular plate 64 structure. The left support rotating rod 3 and right support rotating rod 4 are used in conjunction with the insert fixing structure 6. By setting the left support rotating rod 3 and right support rotating rod 4 at the rear of the template unit 1, the fixing plugs 61 on the insert fixing structure 6 are inserted into the inserts of the left support rotating rod 3 and right support rotating rod 4 respectively, thereby fixing the template unit 1. Specific implementation method three:

[0052] Combination Figure 2 — Figure 4This embodiment describes a road concrete formwork installation structure, wherein the left support rotating rod 3 includes a left rotating rod 31, a left insert 32, a left sleeve 33, and a left support 34;

[0053] One end of the left rotating rod 31 is fixedly connected to the left insert 32, and the other end is fixedly connected to the left sleeve 33. The left sleeve 33 is fitted onto the fixed shaft 5 on the left side of the template unit 1, so that the left sleeve 33 can rotate on the fixed shaft 5. The left support 34 supports the bottom of the left sleeve 33, and the left support 34 is fixedly connected to the fixed shaft 5 on the left side of the template unit 1.

[0054] The left rotating rod 31 is fixedly connected to the left insert 32 and the left sleeve 33 by welding. The left insert 32 and the left sleeve 33 are hollow cylindrical structures. The left insert 32 is inserted with a fixing plug 61, and the left sleeve 33 is used to insert a fixing shaft 5. The left support 34 adopts a circular plate structure. The left support 34 supports the bottom of the left sleeve 33 and limits the left sleeve 33, so that the left rotating rod 31 and the right rotating rod 41 of the same template unit 1 can rotate. Specific implementation method four:

[0056] Combination Figure 2 — Figure 4 This embodiment describes a road concrete formwork installation structure, wherein the right support rotating rod 4 includes a right rotating rod 41, a right insert 42, a right sleeve 43, and a right support 44;

[0057] One end of the right rotating rod 41 is fixedly connected to the right insert 42, and the other end is fixedly connected to the right sleeve 43. The right sleeve 43 is fitted onto the fixed shaft 5 on the right side of the template unit 1, so that the right sleeve 43 can rotate on the fixed shaft 5. The right support 44 supports the bottom of the right sleeve 43, and the right support 44 is fixedly connected to the fixed shaft 5 on the right side of the template unit 1.

[0058] The right rotating rod 41 is fixedly connected to the right insert 42 and the right sleeve 43 by welding. The right insert 42 and the right sleeve 43 are hollow cylindrical structures. The right insert 42 is inserted with a fixing plug 61, and the right sleeve 43 is used to insert a fixing shaft 5. The right support 44 adopts a circular plate structure. The right support 44 supports the bottom of the right sleeve 43 and limits the right sleeve 43, so that the right rotating rod 41 and the left rotating rod 31 of the same template unit 1 can rotate. Specific implementation method five:

[0060] Combination Figure 2Or 7 describes this embodiment, which is a road concrete formwork installation structure, wherein the left insert 32 of the left support rotating rod 3 and the right insert 42 of the right support rotating rod 4 on the adjacent formwork unit 1 are provided with insert fixing structures 6.

[0061] After a set of template units 1 is fixed at both ends by the clamping mechanism 2, the left support rotating rod 3 and the right support rotating rod 4 at the rear of each template unit 1 are rotated respectively, so that the left support rotating rod 3 and the right support rotating rod 4 are in a cross structure. Then, the left fixing plug 61 on the insert fixing structure 6 is inserted into the left insert 32 of the left support rotating rod 3, and the right fixing plug 61 on the same insert fixing structure 6 is inserted into the right insert 42 of the right support rotating rod 4. Through the above operation, a set of template units 1 is installed and fixed by the insert fixing structure 6. Specific implementation method six:

[0063] Combination Figure 7 This embodiment describes a road concrete formwork installation structure, wherein the insert fixing structure 6 includes two fixing inserts 61, a crossbeam 62, a top plate 63, a triangular plate 64, and a baffle 65.

[0064] The top of the fixing plug 61 is connected to the top plate 63. A triangular plate 64 is installed between the top plate 63 and the fixing plug 61. Two adjacent fixing plugs 61 are fixedly connected by a crossbeam 62. The baffle 65 is fixedly connected to the fixing plug 61.

[0065] The bottom of the fixing plug 61 is a pointed structure, which is inserted into the ground. The top of the fixing plug 61 is fixedly connected to the top plate 63 by welding. The top plate 63 is a circular steel plate structure. The two ends of the crossbeam 62 are vertically fixedly connected to the two fixing plugs 61 by welding. The crossbeam 62 is a steel bar structure. The triangular plate 64 provides support for the top plate 63. When the fixing plug 61 is inserted into the ground, the contact area between the hammer and the top plate 63 can be increased by striking the top plate 63 on the fixing plug 61, so that the fixing plug 61 can be inserted into the ground smoothly. Specific implementation method seven:

[0067] Combination Figure 2 — Figure 4 This embodiment describes a road concrete formwork installation structure in which fixing inserts 61 are inserted into the left insert 32 of the left support rotating rod 3 and the right insert 42 of the right support rotating rod 4.

[0068] The left support rotating rod 3, left insert 32, and the right support rotating rod 4, right insert 42 are used together through insert fixing structure 6.

[0069] Each template unit 1 only needs to be equipped with a left support rotating rod 3 and a right support rotating rod 4. Each template unit 1 only needs to be fitted with two fixing plugs 61, which replaces the large number of triangular plates 64 structures. The entire installation process of the template unit 1 is time-saving and labor-saving. Detailed implementation method eight:

[0071] Combination Figure 1 — Figure 12 This embodiment describes a road concrete formwork installation structure, wherein the back of the formwork unit 1 is connected to a set of longitudinal stiffening plates 7.

[0072] When installing template unit 1, first insert the pin 12 on the end of template unit 1 into the insertion hole 11 of the adjacent template unit 1, so that the sides of the two template units 1 fit tightly together. The pin 12 has a slot 121. At this time, the slot 121 on the pin 12 enters into one side of the adjacent template unit 1. Then, move the clamping mechanism 2 horizontally. The clamping mechanism 2 has two locking holes 23. The two locking holes 23 pass through the corresponding two pins 12, so that the clamping plate 21 of the clamping mechanism 2 is in contact with the template unit. The side of the clamping mechanism 1 is attached. After attachment, the clamping mechanism 2 is moved vertically downward. The thickness of the clamping plate 21 of the clamping mechanism 2 is slightly smaller than the groove width of the groove 121. Therefore, after the clamping mechanism 2 is moved downward, the insert post 12 is locked to prevent the insert post 12 from falling out of the insertion hole 11. At this time, the hole surface of the locking hole 23 on the clamping mechanism 2 is attached to the groove surface of the groove 121, so that the clamping plate 21 and the insert post 12 are fixed in a cross shape, thereby enabling the rapid installation of two adjacent template units 1.

[0073] The rear part of template unit 1 is equipped with a left support rotating rod 3 and a right support rotating rod 4. After a set of template units 1 is assembled, the left support rotating rod 3 and the right support rotating rod 4 are rotated so that the left support rotating rod 3 and the right support rotating rod 4 are in a cross structure, so that the left insert of the left support rotating rod 3 and the right insert of the right support rotating rod 4 are on the same straight line. Then, the left fixing plug 61 of the plug fixing structure 6 is inserted into the left insert 32 of the left support rotating rod 3, and the right fixing plug 61 of the plug fixing structure 6 is inserted into the right insert 42 of the right support rotating rod 4 of the adjacent template unit 1. The top plate 63 of the plug fixing structure is hammered by the hammer to drive the fixing plug 61 into the ground. According to the above operation, a set of plug fixing structures 6 is used to quickly install a set of template units 1.

[0074] like Figure 12As shown, the left support rod 3 and the right support rod 4 of the template unit 1 can be rotated to form a cross structure. After rotation, the left insert cylinder 32 on the left support rod 3 is positioned on the same horizontal line, and the right insert cylinder 42 on the right support rod 4 is positioned on the same horizontal line. Then...

[0075] The left fixing plug 61 of the plug-in fixing structure 6 is inserted into the left plug 32 of the left support rotating rod 3 and the left plug 32 of the left support rotating rod 3 on the adjacent template unit 1, while the right fixing plug 61 of the plug-in fixing structure 6 is inserted into the right plug 42 of the right support rotating rod 4 on the adjacent template unit 1. The top plate 63 of the plug-in fixing structure is hammered by the hammer to drive the fixing plug 61 into the ground. According to the above operation, a set of plug-in fixing structures 6 will quickly install a set of template units 1.

[0076] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model's technical solution.
