Abstract
Description
Technical Field
[0001] This application relates to the field of road construction technology, for example to a formwork for water-stabilized layer construction. Background Technology
[0002] Currently, water-stabilized layer is short for cement-stabilized crushed stone layer, which is made by using cement-consolidated graded crushed stone, compacted, and cured. The mix proportion of water-stabilized layer should be tested in the laboratory beforehand to determine the cement content, the ratio of coarse to fine aggregates, and the maximum dry density. For large quantities, a water-stabilized layer mixing plant can be used. Because the water-stabilized layer needs to be laid to a certain thickness, formwork needs to be erected on both sides of the water-stabilized layer in advance.
[0003] An existing construction formwork includes: a panel and a fixing structure. The fixing structure is installed on the back of the panel, inserted into the ground, and cooperates with the ground to provide support and restraint for the panel.
[0004] In the process of implementing the embodiments of this disclosure, at least the following problems were found in the related art:
[0005] Because some sections of the road are higher than the paved ground, there is a lack of soil layers on both sides of the water-stabilized layer that can be used to insert fixing structures, requiring additional scaffolding to be erected, which makes construction more difficult.
[0006] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this application, and therefore may include information that does not constitute prior art known to those skilled in the art. Utility Model Content
[0007] To provide a basic understanding of some aspects of the disclosed embodiments, a brief summary is given below. This summary is not intended as a general commentary, nor is it intended to identify key / important components or describe the scope of protection of these embodiments, but rather as a prelude to the detailed description that follows.
[0008] This disclosure provides a water-stabilized layer construction template that eliminates the need for additional scaffolding when the road is higher than the paved ground, reducing construction steps and lowering construction difficulty.
[0009] In some embodiments, the formwork for water-stabilized layer construction includes: a formwork body, a fixing plate, a first fixing rod, and a second fixing rod. The formwork body has a snap-fit groove at its bottom and a formwork surface; one end of the fixing plate is detachably connected to the snap-fit groove, and the other end of the fixing plate extends toward the formwork surface to one side of the formwork body; the first fixing rod is disposed on one side of the formwork surface, and its bottom is threadedly connected to the fixing plate, with the bottom end of the first fixing rod protruding from the bottom sidewall of the fixing plate; the bottom end of the second fixing rod is threadedly connected to the top end of the first fixing rod.
[0010] Optionally, a fixing box is fixedly provided at the bottom of the template body, and a snap-fit groove is provided on the bottom side wall of the fixing box, and the end of the fixing box facing away from the template body gradually narrows.
[0011] Optionally, a bolt is provided at one end of the fixing box facing away from the template body, and the bolt passes through the fixing box and is threadedly connected to the fixing pull plate.
[0012] Optionally, the end of the fixed pull plate facing the snap-fit groove is provided with a protruding sleeve, the bottom of which gradually narrows.
[0013] Optionally, the outer periphery of the template body is provided with a flange.
[0014] Optionally, adjacent template bodies are fixedly spliced together by connectors, and the connectors are detachably connected to the side plate.
[0015] Optionally, the plate is provided with a connecting hole and an opening, the connecting hole and the opening are connected, and the connector can be rotatably connected with the connecting hole; the connector can slide into the connecting hole along the opening to fix and splice adjacent template bodies.
[0016] Optionally, the connector includes: a connecting plate, insert rods, and fixing blocks. The outer wall of the connecting plate can rotate relative to the inner wall of the connecting hole, and the connecting plate can slide within the opening; two insert rods are provided, which are fixedly connected to both ends of the connecting plate respectively. When the splicing surfaces of two adjacent template bodies abut together, the two insert rods can be inserted into the connecting holes of two adjacent template bodies to clamp and fix the two template bodies; two fixing blocks are provided, each fixing block being fixedly connected to one insert rod. When the connecting plate is located within the connecting hole, the two fixing blocks can clamp and fix the edges of adjacent template bodies.
[0017] The water-stabilized layer construction template provided in this embodiment can achieve the following technical effects:
[0018] When erecting a water-stabilized layer formwork, multiple formwork bodies are sequentially joined together to enclose the paving space. The formwork surface of the formwork body faces the inside of the road, and the end of the fixing plate connected to the first fixing rod also faces the inside of the road, with the bottom end of the first fixing rod able to be inserted into the ground. The water-stabilized layer paving material is laid in the paving space enclosed by the multiple formwork bodies. After the paving material is filled and laid, it then abuts against the formwork surface, pressing down the first fixing rod, the second fixing rod, and the fixing plate under the paving material. The paving material, together with the first fixing rod, the second fixing rod, and the fixing plate, provides tensile force to the formwork, and the formwork body then provides lateral support to the water-stabilized layer paving material. No additional scaffolding is required, reducing construction steps and lowering construction difficulty. During the compaction of the water-stabilized layer, the compaction equipment can provide downward pressure on the first fixing rod, the second fixing rod, and the fixing plate, reducing the risk of the formwork body being squeezed and displaced.

[0034] It should be noted that, unless otherwise specified, the embodiments and features described in the present disclosure can be combined with each other.
[0035] Combination Figure 1-2As shown in the figure, this embodiment of the present disclosure provides a water-stabilized layer construction template, including: a template body 100, a fixing plate 200, a first fixing rod 300, and a second fixing rod 400. The template body 100 has a snap-fit groove 110 at its bottom and a template surface 120; one end of the fixing plate 200 is detachably connected to the snap-fit groove 110, and the other end of the fixing plate 200 extends toward the template surface 120 to one side of the template body 100; the first fixing rod 300 is disposed on one side of the template surface 120, and its bottom is threadedly connected to the fixing plate 200, with the bottom end of the first fixing rod 300 protruding from the bottom sidewall of the fixing plate 200; the bottom end of the second fixing rod 400 is threadedly connected to the top end of the first fixing rod 300.
[0036] Using the water-stabilized layer construction template provided in this embodiment, when erecting the water-stabilized layer template, multiple template bodies 100 are sequentially joined to enclose the paving space. The template surface 120 of the template body 100 faces the inner side of the road, and the end of the fixing plate 200 connected to the first fixing rod 300 also faces the inner side of the road, with the bottom end of the first fixing rod 300 able to be inserted into the ground. The water-stabilized layer paving material is laid in the paving space enclosed by the multiple template bodies 100. After the paving material is filled and laid, it then abuts against the template surface 120, pressing down the first fixing rod 300, the second fixing rod 400, and the fixing plate 200. The paving material, together with the first fixing rod 300, the second fixing rod 400, and the fixing plate 200, provides tensile force to the template, and the template body 100 provides lateral support to the water-stabilized layer paving material. No additional scaffolding is required, reducing construction steps and lowering construction difficulty. During the compaction process of the water-stabilized layer, the compaction equipment can provide downward pressure to the first fixed rod 300, the second fixed rod 400 and the fixed tie plate 200, reducing the risk of the template body 100 being squeezed and displaced.
[0037] Understandably, since the first fixing rod 300 and the second fixing rod 400 are threaded together, when the thickness of the water-stabilized layer is relatively thin, the second fixing rod 400 can be removed from the first fixing rod 300 to prevent the second fixing rod 400 from protruding from the surface of the water-stabilized layer.
[0038] Understandably, the template surface 120 is the surface in direct contact between the template body 100 and the water-stabilized layer, and the template surface 120 provides lateral support for the water-stabilized layer.
[0039] Specifically, the upper side of the template body 100 is higher than the top of the second fixing rod 400. In this way, the height of the second fixing rod 400 is relatively low, reducing the risk of it protruding from the water-stabilized layer and ensuring the construction effect of the water-stabilized layer.
[0040] Combination Figure 3As shown, optionally, a fixing box 130 is fixedly provided at the bottom of the template body 100, and a snap-fit groove 110 is provided on the bottom side wall of the fixing box 130, and the end of the fixing box 130 facing away from the template body 100 gradually narrows. In this way, the fixing box 130 gradually narrows at one end, occupying relatively less space.
[0041] Specifically, the fixing box 130 has a triangular box-like structure.
[0042] Optionally, a bolt 140 is provided at the end of the fixing box 130 facing away from the template body 100. The bolt 140 passes through the fixing box 130 and is threadedly connected to the fixing pull plate 200. In this way, the threaded connection between the bolt 140 and the fixing pull plate 200 makes installation and disassembly more convenient. The fixing pull plate 200 provides tension to the fixing box 130 and the template body 100 through the bolt 140.
[0043] Specifically, the fixing box 130 has a round hole, through which the bolt 140 passes and is threaded to the fixing pull plate 200. In this way, the contact area between the round hole and the bolt 140 is relatively large, resulting in relatively good stability.
[0044] Optionally, each template body 100 has multiple fixing boxes 130 at its bottom, and each fixing box 130 has a snap-fit groove 110. In this way, the number of fixing boxes 130 is relatively large, and each fixing box 130 corresponds to a fixing pull plate 200, which provides relatively large tension to the template body 100 and relatively high stability.
[0045] Specifically, there are two fixing boxes 130 and two fixing pull plates 200. In this way, the number of fixing boxes 130 is relatively large, and each fixing box 130 corresponds to one fixing pull plate 200, which provides relatively large tension to the template body 100 and relatively high stability.
[0046] Optionally, the fixed pull plate 200 has a protruding sleeve 210 at one end facing the snap-fit groove 110, and the bottom of the protruding sleeve 210 gradually narrows. In this way, the protruding sleeve 210 can be inserted into the ground, improving the stability of the fixed pull plate 200 and reducing the risk of displacement of the fixed pull plate 200 and the template body 100.
[0047] Optionally, the bolt 140 passes through the fixing box 130 and is threaded to the inner wall of the raised sleeve 210. In this way, the contact area between the raised sleeve 210 and the bolt 140 is relatively large, and the connection stability is relatively high.
[0048] Optionally, each fixed tie plate 200 is connected to multiple first fixed rods 300. In this way, the number of first fixed rods 300 is relatively large, and the number of second fixed rods 400 can also be relatively large. During the laying of the water-stabilized layer, the stability is relatively good, and the risk of displacement of the fixed tie plate 200 is relatively low.
[0049] Optionally, each fixing plate is provided with a break groove 220, which is located below the template surface 120. In this way, after the road construction is completed, the fixing plate 200 can be broken along the break groove 220, and the exposed part of the fixing plate 200 can be removed.
[0050] Optionally, the outer periphery of the template body 100 is provided with a side plate 150. In this way, the strength of the template body 100 is increased by the side plate 150, and the risk of bending deformation of the template body 100 is reduced.
[0051] Specifically, the template body 100 is a rectangular plate structure, and the plate 150 includes a vertical plate 151 and a horizontal plate 152. The horizontal plate 152 is fixedly connected to the vertical plate 151, and both the vertical plate 151 and the horizontal plate 152 are fixedly connected to the template body 100.
[0052] Combination Figure 4 and Figure 5 As shown, optionally, adjacent template bodies 100 are fixedly spliced together by connectors 500, and the connectors 500 are detachably connected to the edge plate 150. In this way, the adjacent template bodies 100 are fixedly spliced together by connectors 500, which facilitates the construction of the overall template for the water-stabilized layer, and the detachable connection between the connectors 500 and the edge plate 150 makes installation and disassembly more convenient.
[0053] Specifically, the connector 500 is detachably connected to the vertical plate 151.
[0054] Optionally, the plate 150 is provided with a connecting hole 153 and an opening 154, the connecting hole 153 and the opening 154 communicating with each other, and the connector 500 being rotatably connected to the connecting hole 153; the connector 500 can slide into the connecting hole 153 along the opening 154 to fix and splice adjacent template bodies 100. In this way, when it is necessary to splice and fix adjacent template bodies 100, the two template bodies 100 are brought together so that the two connecting holes 153 and the two openings 154 coincide, and then the connector 500 is slid into the connecting hole 153 along the opening 154, and the connector 500 splices and fixes the two adjacent template bodies 100, which is relatively convenient to operate.
[0055] Optionally, the vertical plate 151 is provided with a connecting hole 153 and an opening 154. In this way, the vertical plates 151 of the two template bodies 100 are brought together, and the template surfaces 120 of the template bodies 100 face the same side, which facilitates the connector 500 to splice and fix the two adjacent template bodies 100.
[0056] Optionally, the connector 500 includes: a connecting plate 510, a plug-in rod 520, and a fixing block 530. The outer wall of the connecting plate 510 can rotate relative to the inner wall of the connecting hole 153, and the connecting plate 510 can slide within the opening 154; two plug-in rods 520 are provided, which are fixedly connected to both ends of the connecting plate 510 respectively. When the splicing surfaces of two adjacent template bodies 100 abut together, the two plug-in rods 520 can be inserted into the connecting holes 153 of the two adjacent template bodies 100 to clamp and fix the two template bodies 100; two fixing blocks 530 are provided, and each fixing block 530 is fixedly connected to one plug-in rod 520. When the connecting plate 510 is located within the connecting hole 153, the two fixing blocks 530 can clamp and fix the edge plate 150 of the adjacent template body 100. In this way, when two adjacent template bodies 100 need to be spliced together, the connecting plate 510 slides into the connecting hole 153 along the opening 154, and rotates the connecting plate 510 in the connecting hole 153, so that the fixing block 530 clamps and fixes the vertical plates 151 of the two template bodies 100.
[0057] The template surfaces 120 of the two template bodies 100 are joined together (combined). Figure 6 As shown, the two plug-in rods 520 can be inserted into the two connecting holes 153 to fix the two template bodies 100, which facilitates transportation and can better protect the template surface 120 of the template body 100.
[0058] Optionally, one of the two fixing blocks 530 is magnetic. In this way, the fixing block 530 can be attracted to the template body 100, reducing the risk of relative rotation of the connecting plate 510 within the connecting hole 153.
