Description

Technical Field

[0001] The present application relates to the field of bridge engineering construction, and in particular to a movable bridge concrete anti-collision guardrail template reinforcement tie rod. Background Art

[0002] During the support and installation of the concrete anti-collision guardrail formwork of bridges, tension screws are currently used in large quantities. A circular hole slightly larger than the diameter of the tension rod is opened on the formwork, and a plastic sleeve is put on to pass the guardrail through the gap between the embedded steel bars. It is then reinforced with steel plate gaskets and nuts.

[0003] However, in actual operation, the guardrail template tie rods and steel bars are prone to conflict: the main reasons are that the three steel bars (φ16mm) in the lower half of the guardrail are arranged in parallel, with a width of 5cm. The small deviation of the embedded steel bars can easily cause the tie rod space to be squeezed; the second is that the difference in the arc length inside and outside the curved section of the bridge causes the tie rods to be slightly deflected, increasing the probability of conflict with the embedded steel bars. This causes the tie rod position to conflict with the embedded steel bars and cannot pass through, so a lot of manpower has to be spent on forcibly adjusting the position of the embedded bars, and even the embedded bars are cut off illegally. Utility Model Content

[0004] The main purpose of the present application is to provide a movable bridge concrete anti-collision guardrail template reinforcement tie rod, which can be flexibly moved to avoid collision.

[0005] In order to achieve the above-mentioned objectives, in the first aspect, the present application provides a movable bridge concrete anti-collision guardrail template reinforcement tie rod, comprising a fixed template, a tie screw fixedly set on the fixed template, and a sleeve sleeved on the outside of the tie screw, the two ends of the tie screw are installed on the fixed template through fasteners, and channel steel pads are respectively provided on the inner sides of both sides of the fixed template for horizontal sliding, the channel steel pad is provided with through holes matched with the sleeve, and the corresponding part of the fixed template is provided with a long strip hole for the sleeve to pass through, the fixed template is provided with a limiting structure for limiting the channel steel pad, and the channel steel pad is provided with a grouting-stopping structure with a grouting-stopping function.

[0006] A further improvement is that the grout-stopping structure is a grout-stopping strip fixedly arranged in the channel steel liner.

[0007] A further improvement is that the stop strip is a hard rubber stop strip with a length of 15 cm and a width of 4.5 cm.

[0008] A further improvement is that the slurry-stopping strip is fixedly connected to the channel steel liner by means of quick-drying adhesive.

[0009] A further improvement is that the fastener is a nut that matches with the end of the tension screw.

[0010] A further improvement is that the sleeve is a plastic sleeve.

[0011] A further improvement is that the limiting structure is two template cross ribs fixedly arranged on the fixed template, and the template cross rib is located between the two template cross ribs.

[0012] A further improvement is that the length of the elongated hole is 8 cm.

[0013] The utility model provides a movable bridge concrete anti-collision guardrail template to reinforce the tie rod. Compared with the prior art, its beneficial effect is that by opening long holes in the template and configuring a channel steel liner with hollow round holes, the tie rod can be flexibly moved, thereby avoiding conflict with the embedded steel bars. The utility model is easy to install and disassemble, and reduces the workload of workers in adjusting the steel bars and the possibility of illegally cutting the embedded steel bars. The utility model has low cost and good use effect, and is worthy of rapid promotion. In addition, a grouting stop strip is also provided on the channel steel liner, and the channel steel liner is used to replace the original steel plate gasket for fixing, while taking into account the grouting stop effect of the long holes.

[0026] like Figure 1-Figure 4 As shown, a movable bridge concrete anti-collision guardrail template reinforcement tie rod includes a fixed template 6, a tie screw 1 fixedly set on the fixed template 6, and a sleeve 7 sleeved on the outside of the tie screw 1, the two ends of the tie screw 1 are installed on the fixed template 6 by fasteners 2, and channel steel pads 3 are respectively provided on the inner sides of both sides of the fixed template 6 for horizontal sliding. The channel steel pad 3 is provided with a through hole matched with the sleeve 7, and the corresponding part of the fixed template 6 is provided with a long strip hole for the sleeve 7 to pass through. The fixed template 6 is provided with a limiting structure for limiting the channel steel pad 3, and the channel steel pad 3 is provided with a grouting stop structure with a grouting stop function.

[0027] In this embodiment, preferably, the stop grouting structure is a stop grouting strip 4 fixedly arranged in the channel steel liner 3, and the stop grouting strip 4 is a hard rubber stop grouting strip 4, the length of which is 15 cm and the width of which is 4.5 cm.

[0028] In order to facilitate processing and manufacturing, the stop strip 4 is fixedly connected to the channel steel liner 3 by quick-drying glue.

[0029] Preferably, the fastener 2 is a nut matched with the end of the tension screw 1.

[0030] In order to save costs while ensuring good protection for the tension screw 1 , the sleeve 7 is a plastic sleeve 7 .

[0031] Preferably, the limiting structure is two template transverse ribs 5 fixedly arranged on the fixed template 6, and the template transverse ribs 5 are located between the two template transverse ribs 5, that is, the original template transverse ribs 5 on the fixed template 6 are used as the limiting structure, thereby saving processing steps and making manufacturing more convenient.

[0032] Preferably, the length of the elongated hole is 8 cm.

[0033] The specific manufacturing process is as follows:

[0034] The original circular hole of the template is expanded into a long and narrow hole with a front-to-back length of 8cm and a constant top-to-bottom width, providing space for the tie rod to avoid conflict and move the embedded steel bars;

[0035] The channel steel liner 3 is used to replace the original steel plate gasket for fixing, and the grout stopping function of the flat long hole is also taken into consideration.

[0036] The channel steel liner 3 is constructed as follows:

[0037] ①Use 15cm and [5cm long channel steel as slot gaskets and as receiving parts for transmitting the tightening force of the nut.

[0038] ② Preferably, a hard rubber stop slurry strip 4 is cut into a strip with a length of 15 cm and a height and width of 4.5 cm, embedded in the above-mentioned channel steel slot gasket, and bonded with quick-drying glue to serve as a stop slurry device that is closely attached to the above-mentioned flat and long hole.

[0039] ③ Drill a hollow circular hole slightly larger than the diameter of the plastic sleeve 7 at the corresponding position of the channel steel liner 3, so as to facilitate the plastic sleeve 7 and the tension screw 1 to be inserted into the circular hole in sequence, and finally form a channel steel liner 3 with a circular hole.

[0040] The installation process is as follows:

[0041] ① Place the channel steel liner 3 close to the outside of the template and cover the entire 8cm long and narrow hole. At this time, the upper and lower edges of the channel steel slot are tightly pressed against the corresponding template cross ribs 5.

[0042] ② According to the actual position of the embedded steel bars, move the channel steel liner 3 back and forth within the range of the 8 cm long and narrow hole until the optimal position that does not conflict with the embedded steel bars is found.

[0043] ③ Insert the plastic sleeve 7 and the tension screw 1 into the channel steel liner 3 and the template in sequence, install the nut and tighten it.

[0044] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
