Detailed ways

In order to make the purpose, technical solutions and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Based on the embodiments of the present invention All other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

A connection node structure between a partially laminated slab and a PEC column in an embodiment of the present invention includes a vertically supported prefabricated PEC column 1, a beam 2 horizontally connected to the prefabricated PEC column 1, a partially laminated slab 3 laid on the beam 2, and a local When the laminated slab 3 is laid on the beam 2, the prefabricated PEC column 1 is located on one side of the partial laminated slab 3, and the connection assembly for fixedly connecting the end of the partial laminated slab 3 to the prefabricated PEC column 1, see Figure 1 for the specific effect.

In the field of architectural decoration, the PEC column is poured with concrete in the middle area of the H-shaped steel, and the concrete fills the middle area of the H-shaped steel, making it a rectangular column, supporting the top of the building wall. In this application, a prefabricated PEC column 1 with vertical support is provided. The prefabricated PEC column 1 is a rectangular column composed of main steel parts and concrete filled in the main steel parts. The main steel parts are H-shaped steel, and the floor design It is a partial laminated plate 3. A beam 2 is horizontally connected to the prefabricated PEC column 1, and the laying of the floor slab is realized by laying the partial laminated slab 3 on the beam 2. When the partially laminated slab 3 is laid on the beam 2, the prefabricated PEC column 1 is located on one side of the partially laminated slab 3, and the end of the partially laminated slab 3 is fixedly connected to the prefabricated PEC column 1 through the connecting component, thereby strengthening the floor slab and the frame structure The integrity of the floor can prevent partial cracking of the floor and ensure the safety performance and service life of the floor.

In this embodiment, the end of the partially laminated slab 3 is provided with a stepped structure 31, and the connection assembly includes a concrete post-casting strip 4 filled between the stepped structure 31, the beam 2 and the prefabricated PEC column 1, the specific effect is shown in the figure 1 and 2. A stepped structure 31 is provided at the end of the partially laminated slab 3. Since the prefabricated PEC column 1 is located on one side of the partially laminated slab 3 when the partially laminated slab 3 is laid on the beam 2, the stepped structure 31 at the end of the partially laminated slab 3 is connected to the The prefabricated PEC column 1 is arranged oppositely. When the partial laminated slab 3 is laid on the beam 2, the concrete post-casting strip 4 is filled between the stepped structure 31, the beam 2 and the prefabricated PEC column 1, and after the concrete post-casting strip 4 hardens, the local laminated slab 3 and the precast The PEC column 1 and the beam 2 are fixedly connected, thereby enhancing the integrity of the floor slab and the frame structure, and preventing partial cracking of the floor slab.

The reason why the step-shaped structure 31 is set at the end of the partial laminated plate 3, and the concrete post-casting strip 4 is filled between the step-shaped structure 31, the beam 2 and the prefabricated PEC column 1 is because on the one hand, if the concrete post-casting strip 4 is directly Covering the partial laminated slab 3, the post-concrete strip 4 is solid after hardening and has a certain thickness, so that a bump is formed at the connection between the partial laminated slab 3 and the prefabricated PEC column 1, which affects the aesthetics of the floor slab laying. And set step-shaped structure 31 at the end of partial laminated plate 3, concrete post-casting belt 4 is filled in stepped structure 31, and make the concrete post-casting belt 4 after filling and the top surface of partial laminated plate 3 flush, thereby in After the concrete post-pouring belt 4 is hardened, the top surface of the partially laminated slab 3 remains flat, making the laying of the floor slab more beautiful.

On the other hand, because the prefabricated PEC column 1 is located on the side of the end of the partial laminated plate 3, there is a gap between the prefabricated PEC column 1 and the partial laminated plate 3. If only the gap between the prefabricated PEC column 1 and the partial laminated plate 3 Fill the concrete post-cast belt 4 and make the top surface of the concrete post-cast belt 4 flush with the top surface of the partial laminated slab 3 to ensure that the top surface of the partial laminated slab 3 is flat, thereby ensuring the aesthetics of the floor slab. However, due to the prefabricated PEC The gap between the column 1 and the partially laminated slab 3 is small, and the fixed connection between the prefabricated PEC column 1 and the ends of the partially laminated slab 3 and the beam 2 through the concrete post-casting tape 4 filled in the gap will cause local The fixed connection between the laminated slab 3 and the prefabricated PEC column 1 and the beam 2 is not firm enough, thus affecting the stability of the floor slab laying. A step-shaped structure 31 is set at the end of the partial laminated plate 3, and the concrete post-casting belt 4 is filled between the step-shaped structure 31, the beam 2 and the prefabricated PEC column 1, which can increase the filling amount of concrete and increase the size of the concrete post-casting belt. 4 and the contact area between the partial laminated plate 3, so that the fixed connection between the partial laminated plate 3 and the prefabricated PEC column 1 and the beam 2 is more firm.

In this embodiment, the end of the partially laminated slab 3 is provided with a rib 32 extending from the stepped structure 31, and when the post-cast concrete strip 4 is filled between the stepped structure 31, the beam 2 and the prefabricated PEC column 1 , the reinforcement 32 is coated, and the specific effect is shown in Fig. 1 and Fig. 2 . Ribs 32 are extended from the stepped structure 31 at the end of the partially laminated slab 3, and when the post-concrete strip 4 is filled between the stepped structure 31, the beam 2 and the prefabricated PEC column 1, the post-concrete strip 4 will fill the slab The ribs 32 are covered, so that after the concrete post-casting strips 4 are hardened, the slab bars 32 are located between the concrete post-casting strips 4 and are fixedly connected with the concrete post-casting strips 4, thereby further strengthening the local laminated slab 3 and the prefabricated PEC column 1 and the beam The connection strength between 2.

In the present application, the ribs 32 can be multiple extending from the stepped structure 31 at the end of the partial laminated plate 3, the more the ribs 32 are, the more connected the filled concrete post-casting belt 4 will be. The more reliable, that is, the stronger the connection strength between the partially laminated plate 3 and the prefabricated PEC column 1 and the beam 2 is. However, the greater the number of ribs 32, the greater the processing cost of the partially laminated slab 3, thereby increasing the cost of floor laying. Therefore, in actual use, the number of ribs 32 can be set according to user requirements.

In this embodiment, the connection assembly also includes distribution bars 5 laid between the stepped structure 31 and the prefabricated PEC column 1, when the concrete post-casting strip 4 is filled between the stepped structure 31, the beam 2 and the prefabricated PEC column 1 , and wrap the distribution rib 5, the specific effect is shown in Fig. 1 and Fig. 2 . When the stepped structure 31 at the end of the partial laminated plate 3, the beam 2 and the prefabricated PEC column are laid with distribution bars 5, and the concrete post-casting strip 4 is filled between the stepped structure 31, the beam 2 and the prefabricated PEC column 1 , the distribution bars 5 are covered, so that after the concrete post-casting belt 4 is hardened, the distribution bars 5 are distributed in the concrete post-casting belt 4, and the structural strength of the concrete post-casting belt 4 is strengthened, so that the concrete post-casting belt 4 pairs are partially stacked The fixed connection between the plywood 3 and the prefabricated PEC column 1 and the beam 2 is more stable.

In this embodiment, the connecting assembly further includes a reinforcing member 6 whose one end is fixedly connected to the prefabricated PEC column 1 and the other end is fixedly connected to the rib 32 , the specific effect is shown in FIG. 2 . In this application, a reinforcing member 6 is also provided. One end of the reinforcing member 6 is fixedly connected to the prefabricated PEC column 1, and the other end is fixedly connected to the rib 32 extending from the step structure at the end of the partial laminated plate 3, thereby further strengthening the local The connection strength between laminated plate 3 and prefabricated PEC column 1.

When concrete is filled between the stepped structure 31, the beam 2, and the prefabricated PEC column 1, the filled concrete post-cast belt 4 covers the reinforcement 6. On the one hand, after the concrete post-cast belt 4 hardens, the reinforcement 6 is located In the belt 4, it is fixedly connected with the concrete post-casting belt 4, so as to enhance the integrity of the floor slab and the frame structure, and prevent partial cracking of the floor slab; The joints of the prefabricated PEC columns 1 are kept flat and flush with the top surface of the partially laminated slab 3, thereby improving the aesthetics of the floor slab laying.

In this embodiment, the reinforcement 6 includes a sealing plate 61 whose back is fixedly connected to the prefabricated PEC column 1, and a reinforcing rib 62 whose one end is fixedly connected to the front of the sealing plate 61, and the other end is fixedly connected to the rib 32. The specific effect is shown in the figure 2. The reinforcement 6 includes a sealing plate 61 and a reinforcing rib 62. The back of the sealing plate 61 is fixedly connected to the prefabricated PEC column 1. One end of the reinforcing rib 62 can be fixedly connected to the front of the sealing plate 61 by welding, and the other end is connected to the rib 32 Binding parts can be used for fixed connection, so that the partially laminated slab 3 and the prefabricated PEC column 1 are fixedly connected, further enhancing the integrity of the floor slab and the frame structure, and preventing partial cracking of the floor slab.

When the concrete post-casting strip 4 is filled between the stepped structure 31, the beam 2 and the prefabricated PEC column 1, the concrete post-casting strip 4 will cover the sealing plate 61 and the reinforcing rib 62, because the filling between the stepped structure 31, the beam 2 and the The concrete top surface between the prefabricated PEC columns 1 should be flush with the top surface of the partial laminated slab 3, so when the partial laminated slab 3 is laid on the beam 2, the fixed height of the sealing plate 61 on the prefabricated PEC column 1 cannot exceed the partial laminated slab 3, preventing the top of the sealing plate 61 from being exposed outside the concrete post-casting belt 4 filled between the stepped structure 31, the beam 2 and the prefabricated PEC column 1, not only reducing the The connection strength of the slab also affects the aesthetics of the floor slab laying.

In this embodiment, both ends of the back of the sealing plate 61 are fixedly connected to the flange of the main steel part of the prefabricated PEC column 1, and the reinforcing member 6 also includes an anchor bar 63 that is fixedly connected at one end to the middle part of the back of the closing plate 61, and the anchor bar 63 is located at It is filled between the concrete in the main steel part of the prefabricated PEC column 1, and the specific effect is shown in Fig. 3 and Fig. 4 . In this application, the prefabricated PEC column 1 is a rectangular column composed of main steel parts and concrete filled in the main steel parts. The main steel parts are H-shaped steel, and the H-shaped steel includes wing plates at both ends, and between the two wing plates, The web is connected to the two wing plates at both ends.

Both ends of the back of the sealing plate 61 can be fixedly connected to the wing plates at both ends of the main steel part of the prefabricated PEC column 1 by welding, so that the sealing plate 61 is fixedly connected to the prefabricated PEC column 1 . One end of the anchor bar 63 can be fixed in the middle of the back of the sealing plate 61 by welding, and the other end of the anchor bar 63 extends to the middle of the two wings of the main steel part of the prefabricated PEC column 1. When pouring the prefabricated PEC column 1, The concrete filled in the main steel part of the prefabricated PEC column 1 covers the anchor bar 63, and after the concrete is hardened, the anchor bar 63 is fixedly connected with the prefabricated PEC column 1, so that the sealing plate 61 is further fixedly connected with the prefabricated PEC column 1, so that The connection between the sealing plate 61 and the prefabricated PEC column 1 is more stable, thereby making the connection between the partially laminated plate 3 and the prefabricated PEC column 1 and the beam 2 more stable.

In this application, the two ends of the back of the sealing plate 61 are respectively welded to the flanges at both ends of the main steel part of the prefabricated PEC column 1, and the anchor bar 63 is covered by the concrete filled in the main steel part of the prefabricated PEC column 1. There are two ways to fix the connection between the sealing plate 61 and the prefabricated PEC column 1. On the one hand, in order to improve the connection strength between the sealing plate 61 and the prefabricated PEC column 1, the two ends of the back side of the sealing plate 61 are welded to the two main steel parts of the prefabricated PEC column 1. The middle part of the back of the sealing plate 61 is fixedly connected with the concrete filled in the main steel part of the prefabricated PEC column 1 through the anchor bar 63, so that the connection between the sealing plate 61 and the prefabricated PEC column 1 is more stable.

On the other hand, because the anchor bar 63 will be inserted into the concrete when the concrete filled in the main steel part of the prefabricated PEC column 1 is still in a fluid state, and wait for a period of time for the concrete to harden into a solid state, it will be able to play the role of fixed connection. If only the anchor bar 63 is used to fix the sealing plate 61 and the prefabricated PEC column 1, in the process of waiting for the concrete to harden, the force of the fluid state concrete on the anchor bar 63 is small, and the anchor bar 63 cannot be limited. As mentioned above, the fixed height of the sealing plate 61 on the prefabricated PEC column 1 is required, so an additional limiting device is required to limit the anchor bars 63 and keep the sealing plate 61 installed on the prefabricated PEC column 1 height, causing the structure of the present application to be complex.

If only the two ends of the back of the sealing plate 61 are welded to the flanges at the two ends of the main steel part of the prefabricated PEC column 1, and the sealing plate 61 is fixedly connected to the prefabricated PEC column 1, the thickness of the flanges at both ends of the main steel part of the prefabricated PEC column 1 If it is limited, the connection strength between the sealing plate 61 and the prefabricated PEC column 1 will be poor, thus affecting the connection strength between the partially laminated plate 3 and the prefabricated PEC column 1 . Therefore, in this application, the two ends of the back side of the sealing plate 61 can be welded to the flanges at both ends of the main steel part of the prefabricated PEC column 1, and the installation height of the sealing plate 61 on the prefabricated PEC column 1 can be fixed, and then to the prefabricated PEC column 1 The main steel part is filled with concrete, and after the concrete is hardened, it is fixed with the anchor bar 63, which not only facilitates the laying of the floor slab, but also makes the connection between the sealing plate 61 and the prefabricated PEC column 1 more stable.

In this application, the reinforcement 6 has another embodiment: the reinforcement 6 includes a sleeve 64, a screw 65 and a stop nut 66, and one end of the sleeve 64 is fixedly connected to the web of the main steel part of the prefabricated PEC column 1, The other end is flush with the concrete outer surface filled in the main steel part of the prefabricated PEC column 1, and the end of the sleeve 64 that is flat with the concrete outer surface is provided with a threaded hole, and a through hole 611 is provided on the sealing plate 61, and one end of the screw rod 65 After passing through the through hole 611, it is screwed into the threaded hole, and the limit nut 66 is sleeved on the screw rod 65. When one end of the screw rod 65 penetrates through the through hole 611 and is screwed into the threaded hole, the limit nut 66 is in contact with the sealing plate 61. The effect is shown in Figure 5 and Figure 6.

Since one end of the sleeve 64 is fixedly connected to the web of the main steel part of the prefabricated PEC column 1, when the main steel part of the prefabricated PEC column 1 is filled with concrete, the concrete is wrapped around the periphery of the sleeve 64. After the concrete hardens, the concrete and the sleeve 64 The fixed connection makes the connection between the sleeve 64 and the prefabricated PEC column 1 more stable. The other end of the sleeve 64 is level with the outer surface of the concrete, and the end portion of the sleeve 64 that is level with the outer surface of the concrete is provided with a threaded hole that runs through the sleeve 64, and one end of the screw 65 first passes through the through hole 611 of the sealing plate 61, and then connects with the sleeve. The threaded holes on the 64 are screwed. At this time, the sealing plate 61 is sleeved on the screw rod 65, and then the limit nut 66 is screwed on the screw rod 65 from the end of the screw rod 65 away from the screw connection with the sleeve 64, until the limit nut 66 The side of the sealing plate 61 away from the sleeve 64 abuts against the side of the sealing plate 61 close to the sleeve 64 and the outer surface of the concrete, so that the sealing plate 61 is fixedly connected to the prefabricated PEC column 1 .

It can be foreseen that: the cross-sectional diameter of the limit nut 66 is greater than the cross-sectional diameter of the through hole 611, or a backing plate with a cross-sectional area larger than the cross-sectional area of the through hole 611 is placed between the limit nut 66 and the sealing plate 61, so that the limit When the position nut 66 limits the position of the sealing plate 61 , it can apply force to the side of the sealing plate 61 without passing through the through hole 611 .

Compared with the previous embodiment of the reinforcing member 6, this embodiment has the following advantages: First, in the previous embodiment, the anchor bar 63 is fixed in the middle of the back of the sealing plate 61, and if it is to be filled in the prefabricated PEC column 1 The concrete in the main steel part is fixedly connected with the anchor bar 63. During the pouring process of the prefabricated PEC column 1, the anchor bar 63 should be pre-embedded in the middle of the two wing plates of the main steel part of the prefabricated PEC column 1, and then placed in the prefabricated PEC column 1. The main steel part of 1 is filled with concrete. After the concrete is hardened, the pouring of the prefabricated PEC column 1 is completed. At this time, the prefabricated PEC column 1 and the sealing plate 61 are of an integrated structure, which will make it difficult to transfer the prefabricated PEC column 1 after pouring.

In this embodiment, when the prefabricated PEC column 1 is poured, it is only necessary to weld the sleeve 64 on the web plate of the main steel part of the prefabricated PEC column 1, and then fill with concrete. After the concrete hardens, the prefabricated PEC column 1 After the pouring is completed, the prefabricated PEC column 1 and the sealing plate 61 that have been poured at this time are split structures. The prefabricated PEC column 1 needs to be fixedly connected to the sealing plate 61, and then screwed to the sleeve 64 fixed on the prefabricated PEC column 1 through the screw 65, so the poured prefabricated PEC column 1 and the sealing plate 61 can be transported separately. The prefabricated PEC column 1 and the sealing plate 61 are fixedly connected at the construction site, so that the implementation of the application is simpler and the use is more convenient.

Second, in this embodiment, the sealing plate 61 is fixedly connected to the prefabricated PEC column 1 by screwing, and the sealing plate 61 can also be disassembled from the prefabricated PEC column 1 through the screw 65, so that the sealing plate 61 can be Recycling has the significance of energy saving and environmental protection. In the previous embodiment, the sealing plate 61 is fixedly connected to the prefabricated PEC column 1 through the anchor bar 63. After the prefabricated PEC column 1 is poured, the sealing plate 61 is completely fixed on the prefabricated PEC column 1. Column 1 cannot be disassembled, so that the sealing plate 61 cannot be recycled.

In this embodiment, the through holes 611 are strip-shaped through holes 611 , and the specific effect is shown in FIG. 5 . The through hole 611 provided on the sealing plate 61 is set as a strip-shaped through hole 611, so that the threaded rod 65 penetrates through the through hole 611 and then is screwed with the sleeve 64, and the limit nut 66 abuts against the sealing plate 61, so that the sealing plate 61 When it is fixed on the prefabricated PEC column 1 , it is convenient to adjust the fixed position of the sealing plate 61 on the prefabricated PEC column 1 . Since the fixed connection between the reinforcing member 6 and the partially laminated plate 3 is realized through the fixed connection between the reinforcing rib 62 provided on the front of the sealing plate 61 and the rib 32 of the partially laminated plate 3, the sealing plate 61 is fixed on the prefabricated PEC column 1 The position is adjusted so that when the partial laminated board 3 is laid, the reinforcing rib 62 provided on the front of the sealing plate 61 can better match the position of the partial laminated board 3 rib 32, thereby better connecting the reinforcing rib 62 and the rib 32. Bundling together realizes the fixed connection between the reinforcing member 6 and the partially laminated plate 3 .

In the present application, the strip-shaped through holes 611 can be vertically arranged on the sealing plate 61 , and can also be arranged horizontally on the sealing plate 61 . When the strip-shaped through hole 611 is vertically arranged on the sealing plate 61, the vertical position that the sealing plate 61 is fixed on the prefabricated PEC column 1 can be adjusted; The fixed horizontal position of the sealing plate 61 on the prefabricated PEC column 1 can be determined according to the actual construction situation.

In this embodiment, four beams 2 are horizontally connected to the four sides of the prefabricated PEC column 1 respectively, four local laminated plates 3 are laid on two adjacent beams 2 at both ends, and distribution ribs 5 are laid on the four sides. Between the step-shaped structure 31 of one partially laminated slab 3 and the prefabricated PEC column 1 , the distribution rib 5 is fixedly connected to the ribs 32 of the four partially laminated slabs 3 , the specific effect is shown in FIG. 2 . The prefabricated PEC column 1 is a rectangular column, and a beam 2 is horizontally connected to each of the four sides of the prefabricated PEC column 1. There are four partial laminated plates 3, and the two ends of each partial laminated plate 3 are respectively laid on the crossbeam 2, so that the four partially laminated slabs 3 are enclosed around the prefabricated PEC column 1, and the laying of the floor slab is completed.

The reason why four partial laminated slabs 3 are set is on the one hand to facilitate the laying of the floor slab. If the floor is a whole partial laminated slab 3, transportation and construction will be more difficult. However, if multiple partial laminated slabs 3 are used, the transportation is more convenient. , and transported to the construction site, respectively laying a plurality of partial laminated slabs 3 on the beam 2 makes the laying of the floor slab easier; , when the distribution ribs 5 are laid between the stepped structures 31 of a plurality of partially laminated slabs 3 and the prefabricated PEC column 1, they are also laid in the gap between two adjacent partially laminated slabs 3, and are connected with the ribs 32 at the ends of the partially laminated slabs 3 When the concrete post-cast strip 4 is filled between the stepped structure 31, the beam 2 and the prefabricated PEC column 1, the concrete post-cast strip 4 is also filled in the gap between two adjacent partial superimposed plates 3, so that not only A plurality of partially laminated panels 3 are fixedly connected to the prefabricated PEC column 1, and two adjacent partially laminated panels 3 are also fixedly connected, thereby further enhancing the integrity of the floor slab and the frame structure and preventing partial cracking of the floor slab.

It is foreseeable that the number of partially laminated plates 3 surrounding a prefabricated PEC column 1 may be two, or four, or even more. When there are two partially laminated plates 3 enclosed around a prefabricated PEC column 1, it is only necessary to horizontally connect a beam 2 on the two opposite sides of the prefabricated PEC column 1; When there are four partially laminated panels 3, the four sides of the prefabricated PEC column 1 are horizontally connected to a beam 2. Therefore, when there are multiple partially laminated panels 3 surrounding a prefabricated PEC column 1, it is necessary to The corresponding number of horizontal bars on the side can be connected horizontally, and the specific situation can be determined according to actual construction needs.
