Description

Technical Field

[0001] This invention relates to the field of building construction technology, and in particular to a reinforcing bar guiding device for the installation of prefabricated hollow composite shear walls. Background Technology

[0002] When installing precast hollow composite shear walls, they need to be hoisted to a height of more than one story to allow the reinforcing bars to be inserted through the lower ducts. Compared to grouted sleeve shear walls, the insertion height for the reinforcing bars is generally about half a meter, making it easier for workers to adjust the wall position.

[0003] Currently, the construction method for precast hollow composite shear walls involves workers using long poles to hook onto the reinforcing bars on the side of the wall, adjusting the wall's position, and then inserting the reinforcing bars through corrugated pipe ducts at the bottom of the wall. However, because the reinforcing bars are longer than one story, there is significant swaying, making construction difficult and requiring high positioning accuracy. Installation efficiency is particularly low under windy conditions or when the building's story height exceeds 4 meters.

[0004] Therefore, the large swaying, high construction difficulty, high positioning accuracy requirements, and low installation efficiency of precast hollow composite shear walls during the reinforcement threading process are among the core problems in the construction of precast hollow composite shear walls. How to take effective measures to improve the stability and reliability of the reinforcement threading operation of precast hollow composite shear walls has become a technical problem that urgently needs to be solved by those skilled in the art.

[0005] In view of this, the present invention is hereby proposed. Summary of the Invention

[0009] Preferably, the first guide portion has a first through groove on its snap-fit ​​side, and the second guide portion has a second through groove on its snap-fit ​​side. The first through groove and the second through groove are symmetrically snapped together to form a through channel.

[0010] Preferably, the number of the reinforcing channel is at least one, and the center of the reinforcing channel is located on the center line of the device body in the first state.

[0011] Preferably, the upper outer peripheral walls of the first guide portion and the second guide portion are provided with serrated segments, which are engaged with the inner wall of the bellows channel.

[0012] Preferably, the middle portions of the first guide portion and the middle portions of the second guide portion are rotatably connected by a pivot, and the first guide portion and / or the second guide portion are detachably connected to the pivot, so that the device body can switch between the first state and the second state.

[0013] Preferably, in the first state, the upper part of the reinforcing channel is open and extends into the channel of the corrugated pipe, and the lower part of the reinforcing channel is a closed trumpet-shaped structure.

[0027] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be described in detail below. Obviously, the described embodiments are merely some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0028] This invention provides a guide device for installing precast hollow composite shear walls, comprising a guide device body, which is rotatably connected to a first guide part and a second guide part. The device body has a first state and a second state. In the first state, the first guide part and the second guide part are engaged to form a guide channel, the lower inner diameter of which increases from top to bottom, and the upper parts of the first guide part and the second guide part are respectively engaged with the channels of a corrugated pipe. In the second state, the first guide part and the second guide part are separated from the corrugated pipe.

[0029] This invention features a guiding device body. When the guiding device body is in its first state, the upper parts of the first and second guiding parts are engaged and fixed with the channels of the corrugated pipe, thus securing the guiding device body to the wall. Furthermore, the lower inner diameter of the rebar-threading channel increases from top to bottom, giving the device body greater adaptability. It can effectively guide the rebar through even with changes in rebar diameter or minor adjustments to the threading angle. The low precision requirement for rebar threading reduces construction difficulty and improves the stability and efficiency of the threading operation. These effects are particularly pronounced in windy conditions or when the building height exceeds 4 meters.

[0030] Because the first and second guide parts are detachably rotatably connected, they can be easily and efficiently dismantled after construction is completed. The guide device body can be reused, reducing construction costs.

[0031] As an optional implementation, the first guide portion has a first through groove on its snap-fit ​​side, and the second guide portion has a second through groove on its snap-fit ​​side. The first through groove and the second through groove are symmetrically snapped together to form a through channel.

[0032] Furthermore, the rebar passage is provided along the axial direction of the guide device body to allow the rebar to pass through.

[0033] As an optional implementation, the number of reinforcing channels is at least one, and the center of the reinforcing channel is located on the center line of the device body in the first state.

[0034] The number of reinforcing bar channels can be designed to be one, two, three, or more, depending on the usage requirements.

[0035] As an optional implementation, a first serrated segment is provided on the upper outer peripheral wall of the first guide portion, and a second serrated segment is provided on the upper outer peripheral wall of the second guide portion. The first serrated segment and the second serrated segment are respectively engaged with the inner wall of the channel of the bellows.

[0036] The first and second sawtooth segments are engaged with the inner wall of the bellows, so that the first and second guide parts are fixedly connected to the bellows, ensuring the stability and reliability of the connection between the guide device body and the wall.

[0037] As an optional implementation, the middle portion of the first guide portion and the middle portion of the second guide portion are rotatably connected by a rotating shaft, and the first guide portion and / or the second guide portion are detachably connected to the rotating shaft so that the device body can switch between a first state and a second state.

[0038] Furthermore, a first rotating hole is provided in the middle of the first guide part, and a second rotating hole is provided in the middle of the second guide part. The rotating shaft passes through the first rotating hole and the second rotating hole in sequence. The first guide part and the second guide part can rotate about the central axis of the rotating shaft, so that the first guide part and the second guide part can engage or disengage with the channel of the bellows, thereby switching the state of the device body.

[0039] When the rotating shaft is rotatably connected to the first rotating hole and the second rotating hole, a limiting structure detachably connected to the rotating shaft keeps the relative positions of the rotating shaft, the first guide part, and the second guide part locked along the axial direction of the rotating shaft. The limiting structure uses existing technology and will not be described in detail here.

[0040] As an optional implementation, in the first state, the upper part of the reinforcing channel is open and extends into the channel of the corrugated pipe, while the lower part of the reinforcing channel is a closed trumpet-shaped structure.

[0041] Furthermore, the upper part of the first guide and the upper part of the second guide are not connected, so that the upper part of the through channel is open. This arrangement can ensure that the first guide and the second guide are fixedly connected to the channel of the bellows without interfering with the relative rotational movement of the first guide and the second guide.

[0042] The lower parts of the first guide section and the lower parts of the second guide section are interlocked, making the lower part of the rebar passage a closed trumpet-shaped structure. This design makes it easier for the rebar to be inserted into the corrugated pipe, and the positioning accuracy requirement for rebar insertion is low. Whether it is a change in the diameter of the rebar or a fine adjustment of the insertion angle, the rebar can be effectively guided to be inserted, reducing the construction difficulty and improving the stability and efficiency of the rebar insertion operation.

[0043] As an optional implementation, a buckle is provided at the snap-fit ​​connection between the first guide portion and the second guide portion.

[0044] Furthermore, the lower connecting parts of the first and second guide sections are equipped with latches for easy assembly and disassembly. The number of latches can be adjusted according to usage requirements to accommodate different specifications of the guide device body.

[0045] As an optional implementation, the fastener includes a fastener base and a fastener. The fastener is rotatably disposed on a first guide portion, and the fastener base is disposed on a second guide portion. The fastener and the fastener base are snapped together to keep the first guide portion and the second guide portion in a locked relative position at all times.

[0046] The first and second guide parts are quickly snapped together by fasteners and buckle seats to form a stable guide device body. At this time, the first and second guide parts are snapped into the channel of the bellows.

[0047] By separating the fastener and the fastener base, it is easy to separate the first guide section and the second guide section, making the operation convenient.

[0048] The specific structure of the fastener and fastener adopts existing technology, which will not be elaborated here.

[0049] Example 1:

[0050] like Figure 1-5As shown, the present invention provides a guide device for installing precast hollow composite shear walls, including a guide device body 1, which is composed of a first guide part 2 and a second guide part 3 that are rotatably connected in a separable manner; the device body has a first state and a second state. In the first state, the first guide part 2 and the second guide part 3 are fastened together to form a guide channel 4, the lower inner diameter of the guide channel 4 increases from top to bottom, and the upper parts of the first guide part 2 and the second guide part 3 are respectively engaged with the channels of the corrugated pipe 7; in the second state, the first guide part 2 and the second guide part 3 are separated and detached from the corrugated pipe 7.

[0051] This invention provides a guide device body 1, such as... Figure 2 As shown, when the guide device body 1 is in the first state, the upper parts of the first guide part 2 and the second guide part 3 are engaged and fixed with the channels of the corrugated pipe 7, thus fixing the guide device body 1 to the wall 8. Furthermore, the lower inner diameter of the rebar passage 4 increases from top to bottom, giving the device body greater adaptability. Whether it's a change in the diameter of the rebar 9 or a fine adjustment of the rebar insertion angle, it can effectively guide the rebar 9 through. The positioning accuracy requirement for rebar insertion is low, reducing construction difficulty and improving the stability and efficiency of the rebar insertion operation. This effect is particularly significant under windy conditions or when the building height reaches 4 meters or more.

[0052] like Figure 3 , 4 As shown, since the first guide part 2 and the second guide part 3 are detachably rotatably connected, they can be easily and efficiently dismantled after construction is completed. The guide device body 1 can be reused, reducing construction costs.

[0053] As an optional implementation, the first guide portion 2 has a first through groove 23 on its snap-fit ​​side, and the second guide portion 3 has a second through groove 33 on its snap-fit ​​side. The first through groove 23 and the second through groove 33 are symmetrically snapped together to form a through channel 4.

[0054] Furthermore, the reinforcing bar channel 4 is arranged axially along the guide device body 1 to allow the reinforcing bar 9 to pass through.

[0055] As an optional implementation, such as Figure 5 As shown, the number of reinforcing channels 4 is set to one, and the center of the reinforcing channel 4 is located on the center line of the device body in the first state.

[0056] As an optional implementation, such as Figure 1 , 2 As shown in Figures 3 and 4, a first serrated section 21 is provided on the upper outer peripheral wall of the first guide section 2, and a second serrated section 31 is provided on the upper outer peripheral wall of the second guide section 3. The first serrated section 21 and the second serrated section 31 are respectively engaged with the inner wall of the channel of the bellows 7.

[0057] The first serrated section 21 and the second serrated section 31 are engaged with the inner wall of the channel of the corrugated pipe 7, so that the first guide part 2 and the second guide part 3 are fixedly connected to the corrugated pipe 7 respectively, ensuring the stability and reliability of the connection between the guide device body 1 and the wall 8.

[0058] As an optional implementation, such as Figure 1-5 As shown, the middle part of the first guide part 2 and the middle part of the second guide part 3 are rotatably connected by a rotating shaft 5. The first guide part 2 and / or the second guide part 3 are detachably connected to the rotating shaft 5 so that the device body can switch between the first state and the second state.

[0059] Furthermore, the first guide part 2 is symmetrically provided with a first rotating hole 22 in the middle, and the second guide part 3 is symmetrically provided with a second rotating hole 32 in the middle. The rotating shaft 5 passes through the first rotating hole 22 and the second rotating hole 32 in sequence. The first guide part 2 and the second guide part 3 can rotate about the central axis of the rotating shaft 5 as the rotation axis 5, so that the first guide part 2 and the second guide part 3 can be engaged or disengaged from the channel of the bellows 7, thereby switching the state of the device body.

[0060] When the rotating shaft 5 is rotatably connected to the first rotating hole 22 and the second rotating hole 32, a limiting structure detachably connected to the rotating shaft 5 keeps the relative positions of the rotating shaft 5, the first guide part 2, and the second guide part 3 along the axial direction of the rotating shaft 5 locked. The limiting structure uses existing technology and will not be described in detail here.

[0061] As an optional implementation, in the first state, the upper part of the reinforcing channel 4 is a partially open structure 41 that extends into the channel of the corrugated pipe 7, and the lower part of the reinforcing channel 4 is a closed trumpet-shaped structure 42.

[0062] Furthermore, such as Figure 1 As shown, the upper part of the first guide part 2 and the upper part of the second guide part 3 are not connected, so that the upper part of the through-rib channel 4 is open. This arrangement can ensure that the first guide part 2 and the second guide part 3 are fixedly connected to the channel of the bellows 7 without interfering with the relative rotational movement of the first guide part 2 and the second guide part 3.

[0063] The lower part of the first guide part 2 and the lower part of the second guide part 3 are fastened together, so that the lower part of the rebar passage 4 is a closed trumpet-shaped structure 42. This setting makes it easier for the rebar 9 to be inserted into the corrugated pipe 7. The positioning accuracy requirement for rebar insertion is low. Whether it is a change in the diameter of the rebar 9 or a fine adjustment of the insertion angle, the rebar 9 can be effectively guided to be inserted, reducing the construction difficulty and improving the stability and efficiency of the rebar insertion operation.

[0064] As an optional implementation, such as Figure 1-5As shown, a buckle 6 is provided at the fastening connection between the first guide part 2 and the second guide part 3.

[0065] Furthermore, the lower connecting parts of the first guide section 2 and the second guide section 3 are provided with latches 6 for easy assembly and disassembly. The number of latches 6 can be set according to usage requirements to accommodate different specifications of the guide device body 1.

[0066] As an optional implementation, the fastener 6 includes a fastener base and a fastener. The fastener is rotatably disposed on the first guide portion 2, and the fastener base is disposed on the second guide portion 3. The fastener and the fastener base are snapped together to keep the first guide portion 2 and the second guide portion 3 in a locked relative position at all times.

[0067] The fasteners and buckle seats are connected so that the first guide part 2 and the second guide part 3 can be quickly fastened together to form a stable guide device body 1. At this time, the first guide part 2 and the second guide part 3 are connected to the channel of the bellows 7.

[0068] By separating the fastener and the fastener base, it is convenient to separate the first guide part 2 and the second guide part 3 in the future, making the operation easy.

[0069] The specific structure of the fastener and fastener adopts existing technology, which will not be elaborated here.
