[0002] When constructing the stabilization layer of a cement road, it is necessary to support the formwork on both sides of the road to shape the concrete; after the formwork is laid, additional devices are needed to reinforce the formwork.

[0003] Chinese patent publication number CN215482153U discloses an inner-pull type cement stabilization layer formwork fixing system, including an inner pull rod, a formwork and fixing nails. One end of the inner pull rod is provided with two parallel cross bars for connecting and fixing with the rectangular holes on the formwork, and the other end of the inner pull rod is bent into a hook-shaped structure for inserting the fixing nails. During use, the inner pull rod needs to be turned 90 degrees, which increases the workload of workers; in addition, during the compaction process, the cross bar connected to the formwork is prone to welding, causing one of the cross bars to fall off, and the stability of the formwork is poor, which is not conducive to the fixation of the cement stabilization layer and affects the construction quality.

DETAILED DESCRIPTION

[0030] The utility model will be further described below in conjunction with the accompanying drawings.

[0031] like Figures 1 to 11 As shown, a cement stabilization layer formwork fixing device comprises an inner pull rod, a formwork 7 and a fixing nail 9; the inner pull rod comprises a first rod body 2 and a second rod body 3, one end of the first rod body 2 is welded with a ring joint 1, the other end of the first rod body 2 is bent and connected to one end of the second rod body 3, a support rod 4 perpendicular to the other end of the second rod body 3 is welded below, the tail end of the second rod body 3 is bent into a U-shaped structure 5 or punched into a hole-shaped structure 6; the side wall of the formwork 7 is provided with a plurality of concave holes 8 with protrusions.

[0032] The first rod body 2 and the second rod body 3 are integrally formed, and the length of the first rod body 2 is smaller than that of the second rod body 3 .

[0033] The size of the annular joint 1 matches the protrusion and the concave hole 8; the ring of the annular joint is circular. Figure 2 , Figure 4The first annular joint 11, the second annular joint 12, or the arc-shaped triangle as shown in FIG. Figure 5 , Figure 6 The third and fourth annular joints are shown.

[0034] like Fig.11 As shown, when the concave holes 8 are arranged in a row in the direction parallel to the template, in order to facilitate the annular joint 1 to be sleeved on the protrusion of the template, the protrusion is protruding upward from the bottom of the template 7, so the concave holes 8 on the template are inverted concave. Considering that the direction of the concave holes 8 needs to be confirmed when placing the template, in order to facilitate the placement of the template, as shown in FIG. Fig.12 As shown, the concave holes 8 are arranged in two rows in the parallel direction of the template 7. At this time, symmetrical concave holes 8 are arranged on the template, so there is no need to confirm the direction of the template, and the annular joint can be sleeved on the concave holes 8 whether it is placed upright or upside down.

[0035] In order to make the connection between the annular joint 1 and the first rod body 2 more firmly, the end of the annular joint 1 is wound and welded with the first rod body 2 or welded in parallel, as shown in FIG. Figures 1 to 10 As shown, this increases the welding area and enables the annular joint to be more firmly sleeved on the template, thereby avoiding the open welding or falling off of the inner tie rod during use.

[0036] In order to facilitate the annular joint 1 to pass through the concave hole 8, the distance from the top of the protrusion to the top of the concave hole 8 matches the height of the annular joint 1. Fig.13 As shown, there are at least four shapes of the concave holes 8.

[0037] The support rod 4 is welded through the first and second ends of the U-shaped structure 5, so that the U-shaped structure forms a closed space, which is convenient for fixing and inserting steel nails.

[0038] Since the inner tie rod annular joint 1 and the tail end of the inner tie rod have different styles, the inner tie rod has eight different combinations, as shown in FIG. Figures 3 to 10 As shown, the inner pull rod adopts a combination form of a first annular joint and a U-shaped structure at the tail end; the inner pull rod adopts a combination form of a first annular joint and a hole-shaped structure at the tail end; the inner pull rod adopts a combination form of a second annular joint and a U-shaped structure at the tail end; the inner pull rod adopts a combination form of a second annular joint and a hole-shaped structure at the tail end; the inner pull rod adopts a combination form of a third annular joint and a U-shaped structure at the tail end; the inner pull rod adopts a combination form of a third annular joint and a hole-shaped structure at the tail end; the inner pull rod adopts a combination form of a fourth annular joint and a U-shaped structure at the tail end; the inner pull rod adopts a combination form of a fourth annular joint and a hole-shaped structure at the tail end.

[0039] The working process of this utility model: Fig.11 , 14As shown, first place the template 7 outside the edge of the road base layer 15; hold the inner tie rod, pass the annular joint 1 through the concave hole 8, and directly sleeve it on the protrusion, and then fix the tail end of the inner tie rod to the base layer 15 with a steel nail 9. At this time, the support rod 4 is close to the upper surface of the base layer 15; after paving the cement 10, compacting and curing, remove the annular joint to separate the template 7 from the inner tie rod, and complete the removal of the template 7.
