Description

Technical Field

[0001] The invention belongs to the technical field of civil engineering construction, and in particular relates to a vibrating device for sleeve grouting, a sleeve grouting system, and a grouting construction method. Background Art

[0002] In the construction of prefabricated buildings, the connection of vertical steel bars between prefabricated columns, between beams, or between beams and columns is usually made by grouting sleeves. Sleeve grouting usually adopts two methods: independent grouting and connecting cavity grouting. This case only involves the connecting cavity grouting method. After the prefabricated parts are hoisted on site, the preset gaps between the upper and lower prefabricated parts should be sealed with special mortar, which is generally called warehouse building, to form a connecting cavity. The slurry is injected through the grouting port of the sleeve, and the slurry flows into the connecting cavity through the inner cavity of the sleeve, and then flows into the inner cavities of other sleeves, so that the connecting cavity and each sleeve cavity are completely filled with slurry. When the slurry solidifies and reaches a certain strength requirement, the on-site construction is completed.

[0003] The current grouting construction method is to pour the slurry into the grouting port of a sleeve mouth, and the slurry flows in the sleeve cavity and the connecting cavity. When the slurry flows out from the grouting port and the grouting outlet of each sleeve, it is immediately blocked with a plug until all the grouting ports and the grouting outlets are blocked, and the construction is completed. However, due to the following objective factors, the grouting process is not smooth.

[0004] (1) The surface of the prefabricated components was roughened during prefabrication, which caused the slurry to be subject to greater frictional resistance in the connecting cavity, affecting the flow of the slurry.

[0005] (2) The surface of the prefabricated component is dry and has a certain degree of water absorption. It is in a sealed state before grouting and cannot be moistened with water. After the slurry is poured in, the fluidity of the slurry becomes poor due to water loss, which is not conducive to the flow of the slurry in the connecting cavity and the sleeve cavity.

[0006] (3) The height of the connecting cavity is generally only 20mm-30mm. Due to the manufacturing errors of prefabricated components, or if the construction waste in the connecting cavity is not cleaned up before mortar sealing, the local space cross-section of the connecting cavity may be narrow, and the slurry flow may be easily blocked.

[0007] (4) The gap between the steel bar and the inner wall of the sleeve is very small, sometimes only 4mm to 5mm. When the steel bar is offset, the local space becomes even narrower and the slurry has difficulty flowing.

[0008] (5) The water-cement ratio of high-performance grouting slurry is small, and the fluidity of the slurry itself is lower than that of ordinary concrete.

[0009] (6) The slurry contains high-strength quartz sand aggregate. Due to its high specific gravity, quartz sand is easily deposited at the bottom of the slurry, affecting the flow and workability of the slurry. Especially at the bottom of the sleeve, the accumulation of quartz sand is easy to block the slurry rising channel.

[0010] Based on the above factors, it is difficult to ensure that the grouting can proceed smoothly, resulting in the following phenomena:

[0011] 1. Despite increasing the grouting pressure, the slurry cannot flow into the sleeve cavity or out of the sleeve grouting port or grouting outlet due to the accumulation of quartz sand at the bottom of the sleeve cavity. If the grouting pressure is increased blindly at this time, the blockage at the bottom of the sleeve cavity will become more serious, resulting in the failure of the sleeve grouting. At the same time, if the pressure is too high, the sealing mortar is prone to cracks and leakage, making the grouting unable to proceed smoothly.

[0012] 2. Sometimes, in order to minimize the loss of slurry fluidity in the connecting cavity and the sleeve cavity, rapid grouting is adopted, so that the slurry does not have sufficient flow time in the connecting cavity and the sleeve cavity and cannot be fully filled, which is easy to form a cavity. At this time, after the grouting port and the slurry outlet are blocked, the slurry in the sleeve will flow back to the connecting cavity to fill the cavity, and the slurry height in the sleeve will inevitably decrease, which cannot meet the sleeve grouting fullness requirements.

[0013] 3. If the grouting speed is slowed down in order to make the slurry flow fully, the quartz sand in the grouting material is relatively large and is easy to settle at the bottom, affecting the uniformity of the slurry, making the coarse aggregate in the slurry in the sleeve cavity less, its strength becomes lower, and the connection quality does not meet the requirements.

[0014] At present, there is no effective compensation and rectification measure for the failure of sleeve grouting. The construction quality does not meet the requirements due to the failure of sleeve grouting, and generally the project has to be reworked and started over, which directly causes economic losses and construction period losses to the project construction.

[0015] In the construction of prefabricated structures, the quality of vertical steel bar connections is the key to the reliability of the entire structure. If the construction quality is unqualified or there are quality risks, it will seriously affect the reliability and safety performance of the building structure. At present, the shear wall prefabricated concrete building system adopted in my country is seriously affected by the problem of grouting quality reliability, which is difficult to solve. In some areas, it is precisely because of this factor and the lack of ideal sleeve grouting quality detection methods that the use of shear wall prefabricated systems is restricted or even prohibited. Bridge structures bear large loads, and the dynamic loads borne by buildings are more complex. They have higher requirements for the quality reliability of vertical steel bar connections, and their promotion and application are more hindered.

[0016] In summary, there is an urgent need for a facility and construction method that can improve the quality reliability of sleeve grouting to meet the quality reliability requirements of steel bar connection construction of structural parts. Summary of the invention

[0017] In view of the above problems, the present invention aims to provide a vibrating device for sleeve grouting, which can make the grouting process smooth and the grouting quality reliable, and a sleeve grouting system, and also provides a corresponding grouting construction method. It can be used in the grouting construction of the connecting cavity of the steel bar grouting sleeve connection of the assembled prefabricated structural parts to solve the difficulties faced by the promotion and application of the concrete assembled structure system.

[0018] The technical solution to the problem solved by the present invention is: a vibrating device for sleeve grouting, comprising at least one vibration source, multiple first vibrators, at least one second vibrator, and multiple vibration rings, each two adjacent vibration rings are connected by a first vibrator to form a network structure, the vibration source is connected to at least one vibration ring by a second vibrator, and the vibration source can transmit vibration to each vibration ring through the first vibrator and the second vibrator.

[0019] In the above scheme, the first and second vibration transmitters are used to transmit vibrations. The vibration source is used to generate vibrations, and a vibration source with adjustable power is preferred.

[0020] Furthermore, the vibration ring, the first vibration transmitter, and the second vibration transmitter are rigid steel wires, and the first vibration transmitter, the second vibration transmitter, and the vibration ring are rigidly connected.

[0021] The vibration ring is arranged according to the steel bar conditions, one is arranged for each steel bar, and is inserted into the steel bar. The vibration rings are connected by a vibration net unit, and the vibration net unit is composed of a plurality of first vibrators connected, and the outer contour of the vibration net unit is evenly arranged according to the shape of the connecting cavity and the arrangement of the steel bars. In a preferred scheme, the vibration rings are arranged in two rows, and the front row and the rear row are staggered; the vibration rings in the front row are connected to the adjacent rear row vibration rings through the vibration net unit, and the vibration net unit is composed of a plurality of first vibrators connected, and the outer contour of the vibration net unit is a rectangle, and the vibration rings in the front row and the adjacent rear row vibration rings are respectively located at the diagonal vertices of the rectangular vibration net unit, and the first vibrators that rigidly connect the vibration rings in the front row and the adjacent rear row vibration rings are arranged on the diagonal line of the rectangle.

[0022] Furthermore, there are multiple vibration network units, which are connected to each other in sequence to form the entire vibration network.

[0023] The purpose of setting up a vibration network is to enable the first vibrator to be evenly distributed in the communicating cavity, so that the vibration covers all parts of the communicating cavity, thereby better increasing fluidity.

[0024] The present invention also provides a sleeve grouting system, comprising a first component and a second component to be connected by grouting, a sleeve pre-buried in the first component, and a protruding steel bar located on the second component, a gap is provided between the second component and the first component, a sealing mortar for sealing is provided at the outer contour of the gap between the first component and the second component, a connecting cavity connected to the sleeve cavity is formed between the first component and the second component, a grouting port and a grouting outlet are reserved on the first component corresponding to the sleeve, and the system also includes the above-mentioned vibrating device for sleeve grouting, the vibration ring and the first vibrator are arranged in the connecting cavity, and the inner diameter of the vibration ring is larger than the outer diameter of the protruding steel bar;

[0025] Each vibration ring is sleeved with a protruding steel bar in one-to-one correspondence and is placed at the root of the protruding steel bar; a gap is left between the vibration ring and the inner wall of the sleeve; the vibration source is arranged outside the first component and the second component, and the second vibration transmitter passes through the sealing mortar.

[0026] The difference from the traditional sleeve grouting system is that the present invention adds a vibrating device, which can vibrate while grouting, so that the slurry flows more smoothly.

[0027] Preferably, adjacent first vibrators, and the first vibrators and the vibration ring are connected to each other to form a vibration network, and the vibration network evenly covers the connecting cavity, thereby ensuring the vibration effect.

[0028] Furthermore, an elastic block is provided at the junction of the second vibration transmitter and the sealing mortar. The elastic block is sealed with the sealing mortar on all sides. The second vibration transmitter passes through the elastic block, and the elastic block and the second vibration transmitter are sealed.

[0029] In the above solution, an elastic block is provided to wrap the second vibration transmitter to ensure that the vibration can be transmitted to the vibration net, and the elastic block may be round or square.

[0030] Preferably, the elastic block is made of elastic rubber, and the inner and outer sides of the elastic block are flush with the edge of the sealing mortar.

[0031] The purpose of setting the above scheme to be flush is to ensure that the second vibrator can vibrate freely and well, and to minimize the vibration power loss.

[0032] Accordingly, the present invention also provides a grouting construction method using the above sleeve grouting system, comprising the following steps:

[0033] a) Before the first component is hoisted, the vibration ring of the vibrating device is sequentially inserted into the protruding steel bars of the second component, and at the same time, the first vibrator is also placed on the surface of the second component;

At the same time, the vibration source is started, and the first vibration transmitter, the second vibration transmitter and the vibration ring are in a vibrating state;

[0036] d) The slurry flows into the communicating cavity through the sleeve cavity, and flows to various parts of the communicating cavity under the action of the first vibrator, filling various parts of the communicating cavity;

[0037] When the communicating cavity is filled with slurry, the slurry flows to each sleeve cavity, and the vibration ring below the sleeve is in a vibrating state. Under the action of vibration, the slurry flows smoothly into each sleeve cavity;

[0038] e) When the slurry flowing into the sleeve cavity rises to the grouting ports of other sleeves, the slurry flows out from the grouting ports of the sleeves. At this time, the grouting ports of the sleeves are plugged with plugs;

[0039] f) The slurry continues to rise in the sleeve cavity. When the slurry rises in the sleeve to the slurry outlets of each sleeve, the slurry flows out from the slurry outlets, and all the slurry outlets that flow out of the slurry are plugged one by one;

DETAILED DESCRIPTION

[0048] For the convenience of description, the description of the relative position relationship of each component (such as up, down, etc.) is described according to the layout direction of the drawings in the specification, and does not limit the structure of this patent.

[0049] like Figures 1-2 As shown, a vibrating device for sleeve grouting includes at least one vibration source 1, a plurality of first vibrators 2, at least one second vibrator 20, and a plurality of vibration rings 4. Adjacent vibration rings 4 are connected via the first vibrators 2. The vibration source 1 is connected to at least one vibration ring 4 via the second vibrator 20. The vibration source 1 can transmit vibration to each vibration ring 4 via the first vibrator 2 and the second vibrator 20.

[0050] The vibration ring 4, the first vibration transmitter 2 and the second vibration transmitter 20 are rigid steel wires, which can be hard steel wires or medium-hard steel wires with a diameter of about 5 mm.

[0051] The first vibrator 2, the second vibrator 20 and the vibration ring 4 are rigidly connected, for example, by welding.

[0052] The vibration rings 4 are arranged in two rows, and the front row and the rear row are staggered. The vibration rings 4 in the front row are connected to the adjacent vibration rings 4 in the rear row through a vibration net unit 18. The vibration net unit 18 is composed of a plurality of first vibrators 2 connected. The outer contour of the vibration net unit 18 is a rectangle. The vibration rings 4 in the front row and the adjacent vibration rings 4 in the rear row are respectively located at the diagonal vertices of the rectangular vibration net unit 18, and the first vibrators 2 that rigidly connect the vibration rings 4 in the front row and the adjacent vibration rings 4 in the rear row are arranged on the diagonal line of the rectangle.

[0053] There are multiple vibration network units 18, which are connected to each other in sequence to form the entire vibration network 5.

[0054] The arrangement of the vibration net is made according to the shape of the connecting cavity 17 . In principle, as long as the vibration net is evenly covered in the connecting cavity 17 , it can vibrate freely in the connecting cavity 17 after being connected to the vibration source 1 .

[0055] This embodiment also provides a sleeve grouting system, including a first member 13 and a second member 8 to be connected by grouting, a sleeve 9 embedded in the first member 13, and a protruding steel bar 6 located on the second member 8. A gap is provided between the second member 8 and the first member 13. A sealing mortar 7 for sealing is provided at the outer contour of the gap between the first member 13 and the second member 8. A connecting cavity 17 connected to the sleeve cavity 10 is formed between the first member 13 and the second member 8. A grouting port 15 and a grout outlet 14 are reserved on the first member 13 corresponding to the sleeve 9.

[0056] The vibrating ring 4 and the first vibrator 2 are arranged in the connecting cavity 17. The vibrating net 5 evenly covers the connecting cavity 17.

[0057] The inner diameter of the vibration ring 4 is larger than the outer diameter of the protruding steel bar 6. The diameter of the vibration ring 4 is 10mm-20mm larger than the reserved protruding steel bar 6, and the specific value is adjusted according to the diameter of the protruding steel bar 6. Each vibration ring 4 is sleeved with a protruding steel bar 6 in a one-to-one correspondence and is placed at the root of the protruding steel bar 6. A gap is left between the vibration ring 4 and the inner wall of the sleeve 9. The vibration ring 4 is used to prevent the formation of obvious obstacles to the inflow of slurry at the entrance of the sleeve cavity 10. When vibrating, it can effectively disperse the accumulated aggregate at the entrance of the sleeve cavity 10, improve the fluidity of the slurry there, and make the slurry flow smoothly into the sleeve cavity 10 for filling. When the center of the vibration ring 4 coincides with the center of the protruding steel bar 6, the effect is best.

[0058] The vibration source 1 is arranged outside the first component 13 and the second component 8. The vibration frequency of the vibration source 1 is infinitely adjustable.

[0059] The second vibrator 20 passes through the sealing mortar 7. An elastic block 3 is provided at the junction of the second vibrator 20 and the sealing mortar 7. The elastic block 3 is sealed around the sealing mortar 7. The second vibrator 20 passes through the elastic block 3, and the elastic block 3 and the second vibrator 20 are sealed.

[0060] The elastic block 3 is preferably made of elastic rubber. The inner and outer sides of the elastic block 3 are flush with the edge of the sealing mortar 7, ensuring that the second vibration transmitter 20 can vibrate freely and minimize vibration power loss.

[0061] At the same time, a grouting construction method using a sleeve grouting system is also provided, comprising the following steps:

[0062] a) After the surface of the component is cleaned, before the first component 13 is hoisted, the vibration ring 4 of the vibrating device is sequentially inserted into the protruding steel bars 6 of the second component 8. At the same time, the vibration net 5 is also placed on the surface of the second component 8.

[0063] b) The first component 13 is hoisted into place, and the extended steel bars 6 are inserted into the sleeve cavity 10 one by one. A gap of 20mm-30mm is left between the first component 13 and the second component 8, and the surrounding is sealed with sealing mortar 7 to construct a connecting cavity 17.

[0064] When sealing with the sealing mortar 7, at least one elastic block 3 is buried in the sealing mortar 7. The inner and outer sides of the elastic block 3 are flush with the edge of the sealing mortar 7. The elastic block 3 and the sealing mortar 7 together play a sealing role. The second vibrator 20 passes through the elastic block 3.

[0065] c) When the sealing mortar 7 reaches the specified strength, the grouting construction is started. The grouting machine 12 is turned on, and the grouting nozzle of the grouting pipe 11 is inserted into the grouting port 15 of one of the sleeves 9 to start grouting. At the same time, the vibration source 1 is started to transmit the vibration to the vibration net 5 and the vibration ring 4 through the second vibration transmitter 20.

[0066] Preferably, the grouting pressure of the grouting machine 12 is adjustable, which is convenient for controlling the grouting speed. The grouting machine 12 is equipped with an instrument with a pressure display, which is convenient for observing the grouting pressure.

[0067] When the grouting pressure gauge shows a rapid increase in pressure during the grouting process, it indicates that the fluidity of the slurry in the connecting cavity 17 or the sleeve cavity 10 has deteriorated, and the vibration frequency or vibration power should be increased at this time. On the contrary, when the grouting pressure gauge shows a rapid decrease in pressure, the vibration frequency or vibration power can be appropriately lowered.

[0068] d) The slurry flows into the connecting cavity 17 through the sleeve cavity 10, and flows to various parts of the connecting cavity 17 under the action of the vibration net 5. Under the action of vibration, the slurry can better overcome the friction resistance of the connecting cavity, while ensuring the workability of the slurry and evenly filling various parts of the connecting cavity 17.

[0069] When the communicating cavity 17 is filled with slurry, the slurry flows to each sleeve cavity 10 , and the vibration ring 4 below the sleeve 9 is in a vibrating state. Under the action of the vibration, the slurry flows smoothly into each sleeve cavity 10 .

[0070] e) When the slurry flowing into the sleeve cavity 10 rises to the other sleeve grouting ports 15, the slurry flows out from the grouting ports 15 of the sleeve 9. At this time, the grouting ports 15 of the sleeves are plugged with plugs.

[0071] f) The slurry continues to rise in the sleeve cavity 10. When the slurry rises in the sleeve 9 to each sleeve slurry outlet 14, the slurry flows out from the slurry outlet 14, and all the slurry outlets 14 that flow out of the slurry are plugged one by one.

[0072] g) Stop vibration, the slurry has filled the connecting cavity 17 and each sleeve cavity 10, pull out the grouting nozzle, seal the grouting port 15 at the grouting end with a plug, and the grouting construction is completed.

[0073] This embodiment mainly takes the grouting construction method of the connecting cavity of the vertical steel bar connection sleeve of the prefabricated component of the building structure as an example. However, the present invention is not limited to the above structural forms, and can be used in the connection between columns and columns, beams and beams, beams and columns, shear walls and shear walls of the building structure; the connection between structural columns and columns, beams and beams, beams and columns in bridges; and the vertical structural steel bar connection of other buildings and structures.
