Description

Technical Field

[0001] This utility model relates to the field of grout testing technology, and in particular to a grout outlet connection device for a grouting sleeve. Background Technology

[0002] Currently, key connection points in precast concrete structures mainly include: grouting sleeve connections, grout-anchored lap connections, bottom joints of vertical precast components, and bonding surfaces of post-cast concrete. Among these, grouting sleeves are currently the most common connection method for vertical components. Quality control of grouting sleeves mainly involves two aspects: grout fullness and grout strength. Currently, there are four main methods for testing grout fullness: endoscopic method, X-ray method, pre-embedded steel wire pull-out method, and pre-embedded sensor method. Grout strength is mainly assessed using surface hardness and direct methods.

[0003] The existing grouting sleeves have the following problems:

[0004] 1. Each method for detecting the fullness of sleeve grouting has obvious shortcomings. There is no environmentally friendly, efficient and reliable way to reflect the fullness of grouting.

[0005] 2. In general construction processes, the grout outlet is not effectively treated, resulting in the grout level only maintaining itself on the lower surface of the outlet. Any cavity between the lower surface of the outlet and the top of the sleeve can be considered a defect. Some projects add rubber stoppers to the outlet, which can solve some cases of incomplete filling, but it cannot detect grout leakage in a timely manner.

[0006] 3. Currently, there are two common methods for testing the strength of grouting material inside the sleeve. One is to cast test blocks for compressive strength. This method cannot achieve true uniformity of conditions and cannot guarantee the authenticity of the test blocks. The other is to use the surface hardness method for testing. This method requires a certain test surface, but it is difficult to ensure the formation of the test surface during actual construction. At the same time, the area of ​​the grout outlet is small, and the influence between test points is inevitable, which further increases the uncertainty of the indirect method of strength testing.

[0007] To address these issues, we developed a grout outlet connection device for the grouting sleeve. Utility Model Content

[0008] The purpose of this utility model is to overcome the shortcomings of the prior art by providing a grout outlet connection device for a grouting sleeve, which has the advantages of facilitating sleeve sealing monitoring, reducing costs, and facilitating the testing of grout strength.

[0028] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0029] Figures 1 to 4 A grouting sleeve outlet connection device includes a transparent plastic storage chamber 30, a plastic pre-installed pipe 10, a connecting pipe 20, and a grouting sleeve 60. The grouting sleeve 60 has an inlet pipe 601 at its bottom and an outlet 606 at its top. The outlet 606 is sealed and inserted into the pre-installed pipe 10. The inner diameter of the outlet 606 is the same as the outer diameter of the pre-installed pipe 10 for easy sealing. The connecting pipe 20 is fixedly connected between the storage chamber 30 and the pre-installed pipe 10. The pre-installed pipe 10, the connecting pipe 20, and the storage chamber 30 form an L-shape. A first reinforcing bar 61 is inserted into the top of the grouting sleeve 60 through a sealing plug 70, and a second reinforcing bar 62 is inserted into the bottom. The first reinforcing bar 61 compacts the grouting material inside the grouting sleeve. Concrete 200 is provided on the outer wall of the grouting sleeve 60 and the pre-installed pipe 100, and grouting material 100 is provided on the inner wall of the grouting sleeve 60. The top end of the grouting sleeve 60 is provided with a through hole 605, and a sealing plug 70 is pressed into the through hole 605.

[0030] The storage chamber 30 is a transparent plastic structure with vertical graduation lines 40 on its outer wall. The outer wall of the storage chamber 30 can be circular, elliptical, or rectangular. The plastic material facilitates the formation of the grouting material on the inner wall of the storage chamber, allows for easy observation of whether the grouting sleeve is leaking, and enables subsequent surface hardness testing. The top of the storage chamber 30 is open, and a liquid level control line 50 is located near the top. The graduation lines 40 facilitate the control of grouting through the feed pipe 601. The grouting material needs to reach or exceed the liquid level control line 50.

[0031] A baffle 604 is provided on the inner wall of the grouting sleeve 60, and the bottom end of the first reinforcing bar 61 abuts against the top end of the baffle 604. The baffle 604 facilitates the abutment and positioning of the first reinforcing bar 61, and also facilitates the injection of grouting material from the lower part to the upper part of the grouting sleeve 60. A first branch pipe 602 and a second branch pipe 603 are provided on the bottom side wall of the grouting sleeve 60. One end of the first branch pipe 602 is fixedly connected to a first plug 64. One end of the second branch pipe 603 is fixedly connected to a second plug 65. Preferably, the first plug 64 and the second plug 65 have the same structural dimensions. The feed pipe 601, the first branch pipe 602, and the second branch pipe 603 are arranged in parallel, and one end of the feed pipe 601 is fixedly connected to a third plug 63. The sealing plug 70 has a central hole 701, which is sealed and inserted into the first reinforcing bar 61. The outer wall of the sealing plug 70 is sealed and inserted into the inner wall of the grouting sleeve 60. After the first branch pipe 602 and the second branch pipe 603 are used to detect whether there is leakage on both sides of the bottom end of the grouting sleeve after the feed pipe 601 is grouted in the grouting sleeve 60, the first branch pipe 602 and the second branch pipe 603 are sealed with plugs if there is no leakage.

[0032] During the factory processing of precast wall and column components, PVC pre-reserved pipes are inserted into the grout outlet of the grouting sleeve for simultaneous pouring. After the precast components are transported to the site, they are assembled and positioned, and grout is applied at the joints. Before grouting, the transfer pipe is connected to the storage chamber and installed onto the pre-reserved pipe. Grouting is then carried out, and grouting is stopped when the grout level reaches or exceeds the liquid level control line. The 601 grouting port of the feed pipe is then sealed. If the liquid level continues to drop during the solidification process, it indicates poor sealing of the grouting sleeve, and the leakage point needs to be located and replenished until the grout level is maintained above the liquid level control line and solidifies. When the grout reaches the test age, the storage chamber is removed, and the transparent plastic on the surface is peeled off. The surface hardness method is first tested on the original grout surface. Subsequently, the grout test blocks in the storage chamber can also be ground flat as compressive strength test specimens.

[0033] The above are merely specific application examples of this utility model and do not constitute any limitation on the scope of protection of this utility model. All technical solutions formed by equivalent transformations or equivalent substitutions fall within the scope of protection of this utility model.
