Description

Technical Field

[0001] The utility model relates to the technical field of building construction, specifically a splicing component for precast component gaps. Background Art

[0002] Precast components refer to components that are pre-fabricated in factories or workshops in advance in construction or engineering projects. These components can be transported to the site for assembly and installation after being manufactured. The prefabrication process of precast components can be carried out simultaneously with on-site construction, shortening the construction period. Production in factories can also better monitor and ensure the quality of components. Components can be made of combinations of concrete, steel structures, wood, or other materials.

[0003] UHPC components are one type of precast components. UHPC components refer to components made of ultra-high performance concrete (Ultra-High Performance Concrete, abbreviated as UHPC), which have excellent durability, high strength, high fire resistance, high chemical corrosion resistance, high workability, and good dimensional stability, etc.

[0004] Currently, the application of precast components, even UHPC components, is becoming more and more popular. Current building designs are constantly pursuing aesthetics and large spans, and constantly introducing new processes to pursue perfect building display effects. Due to the large span, the shapes of building designs are difficult to be formed integrally. Therefore, UHPC components will adopt a prefabrication method of segmented splicing and assembly. When assembling prefabricated UHPC components, the gaps at the splicing joints need to be processed to achieve an aesthetic effect. The existing processes for processing gaps are basically mainly the exposed joint process. The joints of the exposed joint process are exposed, affecting the aesthetics of the building finish surface. In projects using the exposed joint process, basically only materials are filled at the joints, and it is inevitable to have problems such as joint cracking. There are also projects using the hidden joint process, but the actual construction effects basically show a large number of cracking and leakage phenomena, and the aesthetic effects of these splicing gaps are not ideal.

[0005] In view of the above deficiencies, we need to develop a splicing component for precast component gaps to meet the usage requirements of the majority of users. Summary of the Utility Model

[0006] In view of the problems of joint cracking, leakage, and affecting aesthetic effects that occur in the existing jointing methods mentioned above, the technical solution adopted by the utility model to solve its technical problems is:

[0007] A splicing component for precast component gaps includes embedded parts pre-buried in precast components, connecting parts for adjusting the splicing spacing, and elastic buffer parts for buffering the splicing spacing. The elastic buffer parts are arranged between adjacent precast components. The connecting parts are cooperatively connected to the embedded parts to limit the relative positions between adjacent precast components. The embedded parts are arranged on the non-display surface of the precast components.

[0008] Furthermore, the embedded parts include a first embedded part provided on one of the adjacent precast members and a second embedded part provided on the other of the adjacent precast members, and the connecting members are respectively connected to the first embedded part and the second embedded part to limit the relative positions between the adjacent precast members.

[0009] Furthermore, the first embedded part is an embedded nut sleeve, the second embedded part is an embedded perforated plate, and the connecting members are respectively connected to the embedded nut sleeve and the embedded perforated plate to adjust the splicing distance between the adjacent precast members.

[0010] Furthermore, the connecting members include connecting angle members, and the connecting angle members are fixedly connected with reinforcing nuts. The precast member is provided with a precast through hole corresponding to the position of the embedded perforated plate. Fasteners are used to pass through the precast through hole, the embedded perforated plate and the connecting angle member to be connected to the reinforcing nut in cooperation, and fasteners are used to pass through the side of the connecting angle member away from the reinforcing nut and be connected to the embedded nut sleeve in cooperation.

[0011] Furthermore, it further includes a precast plug block for filling the precast through hole. The material of the precast plug block is the same as that of the precast member, the outer contour of the precast plug block is the same as the hole contour of the precast through hole, and the display surface of the filled precast plug block is flush with the display surface of the precast member.

[0012] Furthermore, the embedded parts include embedded sleeves, and the connecting members include connecting column bars. The connecting column bars are provided on one of the adjacent precast members and face the other precast member, and the embedded sleeves are provided on the other of the adjacent precast members for the connecting column bars to extend into.

[0013] Furthermore, the connecting column bar and the embedded sleeve are in clearance fit and coaxially arranged. The length of the connecting column bar is greater than the length of the embedded sleeve, and the connecting column bar passes through the elastic buffer member and extends into the embedded sleeve for connection in cooperation.

[0014] Furthermore, the first embedded part is a first embedded angle member, the second embedded part is a second embedded angle member, the connecting members pass through the first embedded angle member and the second embedded angle member and are connected to fasteners in cooperation, and the elastic buffer member is arranged between the first embedded angle member and the second embedded angle member.

[0015] Furthermore, both the first embedded angle member and the second embedded angle member are provided with embedded fitting surfaces for fitting the surface of the precast member. The first embedded angle member and the second embedded angle member are respectively provided with a first clamping part and a second clamping part perpendicular to the embedded fitting surface and extending in the direction away from the precast member, and the elastic buffer member is arranged between the first clamping part and the second clamping part.

[0016] Further, the connecting member passes through the first clamping portion, the elastic buffer member and the second clamping portion and is cooperatively connected with a connecting fastener. The embedded fitting surfaces of the first embedded corner member and the second embedded corner member extend in the direction of the embedded member to form a corner reinforcement portion for connecting the embedded member.

[0017] The beneficial effects of the present utility model are as follows:

[0018] 1. Before the molding of different precast members respectively, the embedded parts are pre-buried on one side of the non-display surface. The connecting member cooperates to connect the embedded parts on adjacent precast members to adjust the splicing distance between the precast members. An elastic buffer member is also padded between adjacent precast members to avoid substantial collision and friction between the precast members, realizing the gap splicing between the precast members. The precast members are locked by the connecting member and the increase of the joint gap is restricted, avoiding the cracking and leakage of the joint, and ensuring the aesthetic effect of the display surface.

[0019] 2. The embedded parts and the connecting members of the present utility model can adopt a variety of different structures to cope with different splicing positions and meet different splicing requirements. After splicing, filling the same material as the precast members between adjacent precast members can achieve the effect of beautiful joint. The elastic buffer member can relieve a certain degree of thermal expansion and contraction effect of the precast members, reduce the change range of the gap at the splicing position between adjacent precast members, and reduce the influence on the gap distance.

[0020] 3. The present utility model uses a precast plug block made of the same material as the precast member to fill the precast through hole, so that no obvious hole marks will appear on the display surface of the precast member, which can not only meet the process requirements of through hole locking, but also meet the original aesthetic effect of the display surface.

[0027] The following will describe in detail the embodiments of the present utility model with reference to the accompanying drawings.

[0028] As Figures 1 to 6 shown, the precast component gap splicing assembly includes a pre-embedded part 110 pre-buried in the precast component, a connecting piece 120 for adjusting the splicing distance, and an elastic buffer 130 for buffering the splicing distance. The elastic buffer 130 is arranged between adjacent precast components. The connecting piece 120 is cooperatively connected to the pre-embedded part 110 to limit the relative positions of adjacent precast components. The pre-embedded part 110 is arranged on the non-display surface of the precast component.

[0029] Specifically, in some embodiments, when adjacent precast components are spliced, they can be divided into independent component A and component B. The precast components will be arranged in public visible places and have a certain visible area and visible range. Therefore, the precast components are provided with a display surface C visible to the public and a non-display surface D not visible to the public;

[0030] The pre-embedded part 110 is a fixed fitting pre-buried before the precast component is cast and formed. After casting and forming, the pre-embedded part 110 is fixedly connected to the precast component and is used to provide an installation structure that can be cooperatively connected to the connecting piece 120. The connecting piece 120 is used to cooperatively connect the pre-embedded parts 110 pre-buried in different precast components respectively, and lock the pre-embedded part 110 on component A and the pre-embedded part 110 on component B respectively through the connecting piece 120 to limit the relative positions of component A and component B. The elastic buffer 130 is clamped between component A and component B to prevent direct contact between component A and component B from causing substantial collision and friction, which may affect the quality of the precast component, and to avoid cracking and leakage of the precast component splicing through the precast component gap splicing assembly;

[0031] The elastic buffer 130 is a rubber soft block used to pad between component A and component B. In the traditional process, adjacent precast components are spliced in a direct contact manner. During splicing and placement, collisions and surface friction will occur, damaging the quality and appearance of the precast components. Cracking or leakage may occur after long-term use. Moreover, after the thermal expansion and contraction effect caused by the environment, the precast components will lean against each other or separate, and cracking or leakage may also occur. By adding the elastic buffer 130 between the precast components and taking advantage of the softness of the material of the elastic buffer 130 itself, the collisions and friction during splicing can be buffered. It can also prevent the direct leaning against each other between the precast components after the thermal expansion and contraction effect of the precast components, effectively reducing the occurrence of cracking or leakage. After filling the same material between the precast components, relying on the elasticity of the elastic buffer 130 to relieve the occurrence of deformation, the stability of the gap distance is further improved, and the floating range of the gap distance is reduced;

[0032] After the gap splicing is completed, the fastener 140 can be used to lock the connector 120 to prevent the connector 120 from loosening and falling off. Since there are still visible stitches after the gap splicing is completed, the user can fill the gap between component A and component B with a filling material of the same material as the precast component to reduce the visibility of the splicing gap and further improve the aesthetic effect of the splicing gap. The embedded part 110 and the connector 120 are both arranged on the non-display surface D side of the precast component, and no exposed splicing components will be seen on the display surface in the view of the public, ensuring the aesthetic effect of the display surface of the precast component.

[0033] Optionally, in some embodiments, the fastener 140 can be one of a screw, a bolt or a nut.

[0034] As Figures 1 to 6 shown, the embedded part 110 includes a first embedded part provided on one of the adjacent precast components and a second embedded part provided on the other of the adjacent precast components. The connector 120 respectively cooperates with and connects the first embedded part and the second embedded part to limit the relative positions between the adjacent precast components.

[0035] Specifically, in some embodiments, the first embedded part is the embedded part 110 provided on one of component A and component B, the second embedded part is the embedded part 110 provided on the other of component A and component B. The first embedded part is arranged on the side of the precast component close to the second embedded part, and the second embedded part is arranged on the side of the precast component close to the first embedded part to reduce the distance between the first embedded part and the second embedded part, facilitating the connection and locking of the connector 120. The first embedded part and the second embedded part adopt different embedded structures. The first embedded part and the second embedded part are both arranged on the non-display surface D side of the precast component. After using the connector 120 and the fastener 140 to lock, the relative positions between the adjacent precast components are restricted.

[0036] As Figure 1 and Figure 2 shown, the first embedded part is an embedded nut sleeve 21, the second embedded part is an embedded perforated plate 22, and the connecting member 120 is respectively connected to the embedded nut sleeve 21 and the embedded perforated plate 22 to adjust the splicing distance between adjacent precast components.

[0037] Specifically, in some embodiments, the embedded nut sleeve 21 is a sleeve fitting embedded in the precast component for the fastener 140 to extend into and be connected. The embedded nut sleeve 21 is provided with an internal thread, an external hexagon, and a sleeve opening communicating with the outside world, so that when the fastener 140 is connected to the embedded nut sleeve 21, the embedded nut sleeve 21 will not rotate with the rotation of the fastener 140 under the condition of satisfying the thread connection. The embedded perforated plate 22 is a hole plate fitting embedded in the precast component for the fastener 140 to pass through. The side of the embedded perforated plate 22 facing the precast component is provided with a perforated plate reinforcement part 221 for reinforcement connection. The embedded perforated plate 22 is provided with a connection through hole for the fastener 140 to pass through. After pouring, the embedded nut sleeve 21 is formed in one of the component A and the component B, and the embedded perforated plate 22 is formed in the other of the component A and the component B. In use, the fastener 140 passes through one side of the connecting member 120 and is connected to the embedded nut sleeve 21, and the fastener 140 passes through the other side of the connecting member 120 and is connected to the embedded perforated plate 22. By finely adjusting the position of the fastener 140 on the embedded perforated plate 22, the splicing distance is adjusted.

[0038] As Figure 1 and Figure 2 shown, the connecting member 120 includes a connecting angle member 23, the connecting angle member 23 is fixedly connected with a reinforcing nut 24, the precast component is provided with a precast through hole 25 corresponding to the position of the embedded perforated plate 22, and the fastener 140 is used to pass through the precast through hole 25, the embedded perforated plate 22 and the connecting angle member 23 to be connected to the reinforcing nut 24 in cooperation, and the fastener 140 passes through the side of the connecting angle member 23 away from the reinforcing nut 24 and is connected to the embedded nut sleeve 21 in cooperation.

[0039] Specifically, in some embodiments, the connecting angle member 23 is a connecting fitting for connecting the embedded nut sleeve 21 and the embedded perforated plate 22. The connecting angle member 23 can use an angle steel as the main structure. On one side of the connecting angle member 23, a plurality of connecting through holes for the fastener 140 to pass through are respectively provided. At one end of the connecting angle member 23 close to the embedded perforated plate 22 and on the side away from the embedded perforated plate 22, a reinforcing nut 24 is welded. The prefabricated through hole 25 is a process through hole reserved during the casting of the prefabricated component for easy installation. During use, first install the connecting angle member 23 on the embedded nut sleeve 21 with the fastener 140. After the component A and the component B clamp the elastic buffer member 130, then insert the fastener 140 into the prefabricated through hole 25 from one side of the display surface C. The fastener 140 passes through the connecting through hole of the embedded perforated plate 22 and is connected to the reinforcing nut 24. After adjusting the splicing distance between the component A and the component B, lock the fastener 140. With such a design, the connection stability can be further improved. Angle steel is one of the common structural profiles, which is easy to purchase and can reduce costs, and is suitable for mass use in the splicing of prefabricated components.

[0040] As Figure 1 and Figure 2 shown, it further includes a prefabricated plugging block 26 for filling the prefabricated through hole 25. The material of the prefabricated plugging block 26 is the same as that of the prefabricated component. The outer contour of the prefabricated plugging block 26 is the same as the hole contour of the prefabricated through hole 25. After filling, the display surface of the prefabricated plugging block 26 is flush with the display surface of the prefabricated component.

[0041] Specifically, in some embodiments, the prefabricated plugging block 26 is a filling object for filling the prefabricated through hole 25 exposed on the display surface C. In order not to show obvious material differences on the display surface C, the prefabricated plugging block 26 is made of the same concrete material as the prefabricated component. The outer contour of the prefabricated plugging block 26 is the contact surface contour in contact with the prefabricated through hole 25 when installed in the prefabricated through hole 25. The prefabricated plugging block 26 and the prefabricated through hole 25 adopt a clearance fit connection method, and a better display effect can be achieved when the clearance of the fit is controlled within 0.5 mm. After the prefabricated plugging block 26 is installed in the prefabricated through hole 25, the same concrete material is filled in the clearance as the filling material to further reduce the visibility of the installation clearance. After installation, the display light-exposed surface of the prefabricated plugging block 26 is flush with the display surface C of the prefabricated component, making the display surface C of the prefabricated component smoother without a sense of unevenness or dislocation. More specifically, the prefabricated plugging block 26 and the prefabricated through hole 25 can adopt an inclined taper fit to achieve a more tightly and stably connected effect.

[0042] As Figure 3 and Figure 4As shown, the embedded part 110 includes an embedded sleeve 31, the connecting member 120 includes a connecting column rod 32, the connecting column rod 32 is arranged in one of the adjacent precast components and faces the other precast component, and the embedded sleeve 31 is arranged in the other of the adjacent precast components for the connecting column rod 32 to extend into.

[0043] Specifically, in some embodiments, the adjacent precast components are provided with splicing surfaces that are spliced and in contact with each other. The splicing surface of component A facing component B is splicing surface E, and the splicing surface of component B facing component A is splicing surface F. The embedded sleeve 31 is a sleeve member for being pre-embedded in the splicing surface of the precast component, for the connecting column rod 32 to extend into for fitting and installation. The connecting column rod 32 is a column rod member for being pre-embedded in the splicing surface of the precast component. The inner cylinder of the embedded sleeve 31 and the outer shape of the connecting column rod 32 adopt the same shape. The embedded sleeve 31 and the connecting column rod 32 adopt a clearance fit. A plurality of embedded sleeves 31 are pre-embedded in the splicing surface of one of the two precast components, and the mouth of the embedded sleeve 31 is flush with the splicing surface. A plurality of connecting column rods 32 are pre-embedded in the splicing surface of the other of the two precast components, and the connecting column rods 32 extend out of the splicing surface by a certain distance. Each embedded sleeve 31 has a connecting column rod 32 at a corresponding position for easy alignment and installation. During installation, each connecting column rod 32 is extended into the interior of the embedded sleeve 31, and the outer surface of the connecting column rod 32 and the inner surface of the embedded sleeve 31 are in contact with each other to increase the friction force, so that the connecting column rod 32 is difficult to disengage. More specifically, a column rod center hole penetrating along the central axis direction can be opened in the center of the connecting column rod 32, and a column rod side hole communicating with the column rod center hole is opened at the position where the splicing surface of the precast component intersects with the outside of the connecting column rod 32. During use, when the connecting column rod 32 extends into the embedded sleeve 31, the air inside the embedded sleeve 31 is squeezed by the space and discharged to the outside through the column rod center hole and the column rod side hole, making the process of the connecting column rod 32 extending into the embedded sleeve 31 smoother, reducing the installation resistance, and lowering the installation difficulty.

[0044] As Figure 3 and Figure 4 As shown, the connecting column rod 32 and the embedded sleeve 31 are in clearance fit and coaxially arranged. The length of the connecting column rod 32 is greater than the length of the embedded sleeve 31. The connecting column rod 32 passes through the elastic buffer member 130 and extends into the embedded sleeve 31 for fitting connection.

[0045] Specifically, in some embodiments, each connecting column bar 32 is coaxially arranged with the embedded sleeve 31 at the corresponding position. During pouring, first install the connecting column bar 32 and the embedded sleeve 31 and then place them into the concrete to be poured. Adjacent precast components are spaced apart and poured simultaneously. After pouring is completed, separate the two precast components so that the connecting column bar 32 is pulled out of the embedded sleeve 31. This can make the coaxiality of the connecting column bar 32 and the embedded sleeve 31 more accurate. During splicing, the connecting column bar 32 passes through the elastic buffer 130 and extends into the embedded sleeve 31 to limit the position of the elastic buffer 130. Compared with only clamping the elastic buffer 130 between adjacent precast components, the hanging method can better locate the installation position of the elastic buffer 130, avoiding the elastic buffer 130 from loosening and falling due to insufficient local clamping force or too large a gap between adjacent precast components. The elastic buffer 130 is stably arranged between the connecting column bar 32 and the embedded sleeve 31, facilitating the splicing step.

[0046] As Figure 5 and Figure 6 shown, the first embedded part is the first embedded angle part 41, the second embedded part is the second embedded angle part 42, the connecting member 120 passes through the first embedded angle part 41 and the second embedded angle part 42 and is connected with the connecting fastener 140, and the elastic buffer 130 is arranged between the first embedded angle part 41 and the second embedded angle part 42.

[0047] Specifically, in some embodiments, the first embedded angle part 41 is an embedded part installed on the non-display surface D of one of the adjacent precast components near the splicing position for the connecting member 120 to lock. The second embedded angle part 42 is an embedded part installed on the non-display surface D of the other of the adjacent precast components near the splicing position for the connecting member 120 to pass through. The first embedded angle part 41 and the second embedded angle part 42 preferably use angle steel in the profile as the structural main body. Angle steel is one of the common structural profiles, which is easy to purchase and can reduce costs, and is suitable for large-scale use in the splicing of precast components. The structure of the angle steel is provided with a horizontal plane and a vertical plane that are perpendicular to each other. When the horizontal plane is attached to the non-display surface D of the precast component for installation, the vertical plane is perpendicular to the non-display surface D. The vertical plane of the first embedded angle part 41 faces the second embedded angle part 42, and the vertical plane of the second embedded angle part 42 faces the first embedded angle part 41. The vertical plane of the first embedded angle part 41 extends a certain distance beyond the splicing surface of the embedded component where it is located near the other embedded component, and the vertical plane of the second embedded angle part 42 extends a certain distance beyond the splicing surface of the embedded component where it is located near the other embedded component. After the vertical planes of the first embedded angle part 41 and the second embedded angle part 42 come into contact and fit, there is still a certain gap between adjacent precast components, so as to facilitate filling with filling materials. Preferably, a material the same as that of the concrete can be used as the filling material to reduce the visibility of the filling marks and improve the appearance consistency between the filling marks and the precast components;

[0048] To further reduce the tearing of the filling material by adjacent precast components, an elastic buffer member 130 can be provided between the vertical surfaces of the first embedded corner member 41 and the second embedded corner member 42. During installation, the connecting member 120 is successively passed through the first embedded corner member 41, the elastic buffer member 130, and the second embedded corner member 42, or successively passed through the second embedded corner member 42, the elastic buffer member 130, and the first embedded corner member 41, and then the protruding end of the connecting member 120 is locked using the fastener 140. Utilizing the soft characteristics of the material of the elastic buffer member 130 itself, it can buffer the collision and friction during splicing, and can also prevent the direct abutment between precast components after the precast components generate thermal expansion and contraction effects, effectively reducing the occurrence of cracking or leakage. After filling the space between precast components with materials of the same material, relying on the elasticity of the elastic buffer member 130 to relieve the occurrence of deformation, it further improves the stability of the gap distance and reduces the floating range of the gap distance.

[0049] As Figure 5 and Figure 6 shown, both the first embedded corner member 41 and the second embedded corner member 42 are provided with embedded fitting surfaces 43 for fitting the surfaces of the precast components. The first embedded corner member 41 and the second embedded corner member 42 are respectively provided with a first clamping portion 411 and a second clamping portion 421 that are perpendicular to the embedded fitting surface 43 and extend in a direction away from the precast component. The elastic buffer member 130 is disposed between the first clamping portion 411 and the second clamping portion 421.

[0050] Specifically, in some embodiments, the embedded fitting surface 43 is a contact plane for the first embedded corner member 41 and the second embedded corner member 42 to be respectively fitted and installed on the non-display surface D of the precast component. The first clamping portion 411 is an extended structure where the vertical surface of the first embedded corner member 41 is located. The second clamping portion 421 is an extended structure where the vertical surface of the second embedded corner member 42 is located. The first clamping portion 411 and the second clamping portion 421 are arranged in a close-to-opposite manner. The first clamping portion 411 is located on the side of the first embedded corner member 41 close to the second embedded corner member 42, and the second clamping portion 421 is located on the side of the second embedded corner member 42 close to the first embedded corner member 41. Both the first clamping portion 411 and the second clamping portion 421 are provided with through holes for the connecting member 120 to pass through. The connecting member 120 can be a screw or a bolt, and the fastener 140 can be a nut. The threaded end of the connecting member 120 passes through the first clamping portion 411, the elastic buffer member 130, and the second clamping portion 421 and is cooperatively connected with the fastener 140 to limit the gap between adjacent precast components and further improve the splicing stability of adjacent precast components.

[0051] As Figure 5 and Figure 6As shown, the connecting member 120 passes through the first clamping portion 411, the elastic buffer member 130, and the second clamping portion 421 and is cooperatively connected with the fastening member 140. The embedded fitting surface 43 of the first embedded angle member 41 and the embedded fitting surface 43 of the second embedded angle member 42 extend in the direction towards the embedded member to form an angle member reinforcement portion 44 for connecting the embedded member.

[0052] Specifically, in some embodiments, the elastic buffer member 130 is hung between the first clamping portion 411 and the second clamping portion 421 by using the connecting member 120 to limit the installation position of the elastic buffer member 130. Compared with only clamping the elastic buffer member 130 between adjacent precast members, the hanging method can more accurately position the installation position of the elastic buffer member 130, preventing the elastic buffer member 130 from loosening and falling off due to insufficient local clamping force or too large a gap between adjacent precast members. The elastic buffer member 130 is stably arranged between the connecting column bar 32 and the embedded sleeve 31, facilitating the splicing step.

[0053] The angle member reinforcement portion 44 is a reinforcement structure for connecting the first embedded angle member 41 and the second embedded angle member 42 to the precast member during pouring. During pouring, the side of the first embedded angle member 41 facing the angle member reinforcement portion 44 is placed within the pouring range of the precast member, and the embedded fitting surface 43 is flush with the non-display surface D of the precast member. After pouring and forming, the first embedded angle member 41 can be pre-embedded in one of the adjacent precast members. Using the same pouring steps, the second embedded angle member 42 is also pre-embedded in the other of the adjacent precast members. During splicing, the adjacent precast members are brought close together, and the connecting member 120 is passed through the first clamping portion 411, the elastic buffer member 130, and the second clamping portion 421, and the protruding end of the connecting member 120 is locked with the fastening member 140 to achieve the effect of restricting the splicing gap and further improving the splicing stability of the adjacent precast members.

[0054] As Figure 1 and Figure 2 shown, the specific implementation manner of Embodiment 1 of the present utility model is as follows:

[0055] During pouring, two embedded nut sleeves 21 are pre-embedded in the position of member A close to the non-display surface D and close to the splicing surface, and the embedded perforated plate 22 is pre-embedded in the position of member B close to the non-display surface D and close to the splicing surface. The centers of the two embedded nut sleeves 21 and the center of the embedded perforated plate 22 are on the same straight line perpendicular to the splicing surface. A precast through-hole 25 is reserved on member B, and the central axis of the precast through-hole 25 is coaxial with the central axis of the embedded perforated plate 22. After pre-embedding, pouring of member A and member B can be started.

[0056] During splicing, the side of the connecting angle member 23 away from the reinforcing nut 24 approaches the embedded nut sleeve 21. Use headless set screws to pass through the connecting through-holes of the connecting angle member 23 and threadedly connect them to the two embedded nut sleeves 21 respectively. Then, install nuts on the side of the headless set screws away from the embedded nut sleeves 21 until the nuts contact and lock with the connecting angle member 23. Place the elastic buffer member 130 between the splicing surfaces of member A and member B. Then, bring the side of the connecting angle member 23 close to the reinforcing nut 24 close to the embedded perforated plate 22. Insert a flat head screw from one end of the prefabricated through-hole 25 close to the display surface C. The flat head screw passes through the embedded perforated plate 22 and the connecting angle member 23 and locks onto the reinforcing nut 24. Finally, insert the prefabricated plugging block 26 into one end of the prefabricated through-hole 25 close to the display surface C until the exposed surface of the prefabricated plugging block 26 is flush with the display surface C of member B, completing the gap splicing of member A and member B. Finally, fill the splicing joint of member A and member B with the same material as the precast member to form a filled joint, and slightly polish it to complete the splicing.

[0057] In this embodiment, multiple embedded nut sleeves 21 and multiple embedded perforated plates 22 can be pre-embedded in the precast member. According to the length of the splicing gap of the precast member, multiple connecting angle members 23 can be installed to ensure the splicing stability of the gap splicing and improve the splicing firmness.

[0058] As Figure 3 and Figure 4 shown, the specific implementation manner of Embodiment 2 of the present utility model is as follows:

[0059] During pouring, multiple connecting column rods 32 are pre-embedded on the splicing surface of member A close to member B, and multiple embedded sleeves 31 are pre-embedded on the splicing surface of member B close to member A. Each connecting column rod 32 is coaxially arranged with the corresponding embedded sleeve 31. After the pre-embedding placement, pouring of member A and member B can be started.

[0060] During splicing, multiple elastic buffer members 130 are respectively sleeved on each connecting column rod 32 and contact the splicing surface of member A. Align the multiple connecting column rods 32 with the embedded sleeves 31 and insert them for mating connection until the elastic buffer members 130 stop inserting after contacting the splicing surface of member B and being compressed. Adjust the gap distance between the splicing surfaces of member A and member B to be as consistent as possible, completing the gap splicing of member A and member B. Finally, fill the splicing joint of member A and member B with the same material as the precast member to form a filled joint, and slightly polish it to complete the splicing.

[0061] As Figure 5 and Figure 6 shown, the specific implementation manner of Embodiment 3 of the present utility model is as follows:

[0062] During pouring, a plurality of first embedded corner members 41 are pre-embedded at positions on member A close to the non-display surface D and close to the splicing surface, and a plurality of second embedded corner members 42 are pre-embedded at positions on member B close to the non-display surface D and close to the splicing surface. The first clamping portion 411 and the second clamping portion 421 are located between the splicing surfaces of member A and member B, and the through holes of each first embedded corner member 41 are aligned with the through holes of the corresponding second embedded corner member 42 at the corresponding positions.

[0063] During splicing, a plurality of elastic buffer members 130 are respectively arranged between the corresponding first clamping portion 411 and second clamping portion 421. A flat head bolt is inserted from member A and passes through the first clamping portion 411, the elastic buffer member 130 and the second clamping portion 421, and a nut is installed at the protruding end of the flat head bolt until the nut contacts the second clamping portion 421 and is tightened, completing the splicing of the gap between member A and member B. Finally, a material the same as that of the precast member is filled at the splicing joint of member A and member B to form a filled joint, and after slightly polishing, the splicing is completed.

[0064] As Figures 1 to 6 shown, the specific implementation manner of Embodiment 4 of the present utility model is as follows:

[0065] For the precast member gap splicing assembly of this embodiment, any two of the implementation manners of Embodiment 1, Embodiment 2 and Embodiment 3 are applied to the embedding and splicing on member A and frame B. Each group of precast member gap splicing assemblies is arranged in a spaced manner along the splicing gap between member A and frame B, and is used in combination to further enhance the splicing stability between member A and frame B.

[0066] As Figures 1 to 6 shown, the specific implementation manner of Embodiment 5 of the present utility model is as follows:

[0067] For the precast member gap splicing assembly of this embodiment, the implementation manners of Embodiment 1, Embodiment 2 and Embodiment 3 are simultaneously applied to the embedding and splicing on member A and frame B. Each group of precast member gap splicing assemblies is arranged in a spaced manner along the splicing gap between member A and frame B, and is used in combination to further enhance the splicing stability between member A and frame B.

[0068] The above only further illustrates the technical content of the present utility model with embodiments to make it easier for readers to understand, but does not mean that the implementation manners of the present utility model are limited to this. Any technical extension or re-creation made according to the present utility model is protected by the present utility model. The protection scope of the present utility model is subject to the claims.
