Description

Technical Field

[0001] The present invention relates to the technical field of earthquake-resistant foundations, and in particular to an earthquake-resistant foundation for assembled house buildings. Background Art

[0002] Prefabricated house construction is a modern construction method. It prefabricates the various components of a house in a factory and then transports them to the construction site for assembly. It has the advantages of fast construction speed and energy saving and environmental protection. In order to improve the seismic performance of prefabricated house construction, an earthquake-resistant base is generally laid before the house construction is assembled.

[0003] At present, the more mainstream and common earthquake-resistant base is the elastic earthquake-resistant base, which is mainly made of thin steel plates and thin rubber sheets stacked and vulcanized. The bottom and top of the elastic earthquake-resistant base are respectively provided with lower piers and upper piers, which are used to connect the elastic earthquake-resistant base with the foundation and the beams and columns of the house. During the construction of the elastic earthquake-resistant base, it is necessary to first complete the binding of the lower pier steel bars, then fix the embedded components in the steel bars of the lower pier, and finally pour concrete on the lower pier. After the concrete of the lower pier is dried and fixed, the embedded components are used to connect the lower pier with the steel bars of the lower pier. The components are installed and fixed to the main body of the elastic seismic resistant base. In the above construction process, when the embedded components are fixed in the steel bars of the lower pier, they are easily affected by the steel bar binding structure, resulting in deviations in the embedded positions of the embedded components and uneven embedded heights, thereby affecting the subsequent installation and fixation of the main body of the elastic seismic resistant base. Moreover, when fixing the embedded components in the steel bars of the lower pier, it mainly depends on the manual leveling and visual observation of the construction workers, and the accuracy of the installation of the embedded components cannot be guaranteed, resulting in low construction and installation efficiency of the elastic seismic resistant base.

[0004] Therefore, the present invention provides an earthquake-resistant base for prefabricated house construction to meet the needs. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide an earthquake-resistant base for prefabricated house buildings by setting a positioning component. After the construction workers insert the embedded sleeve into the slot, they can judge whether the embedded sleeve is fully inserted into the slot by observing whether the positioning block protrudes from the top of the positioning plate. In addition, the construction workers can observe the protrusion of the positioning block to judge whether the embedded sleeve is vertically inserted into the slot. Through such a setting, not only the relative height between each embedded sleeve and the positioning plate can be judged, but also whether the embedded sleeve and the positioning plate are perpendicular to each other can be judged, thereby ensuring the accuracy of the installation of the embedded sleeve, improving the firmness of the installation of the earthquake-resistant base main body and the accuracy of the installation process. The above setting can solve the problem of low efficiency of embedded steel bar installation during the installation of the earthquake-resistant base at this stage.

[0006] In order to solve the above technical problems, the present invention provides the following technical solutions:

[0007] The bottom plate and the top plate are respectively fixed to the bottom and the top of the buffer column, and the buffer column is formed by overlapping and vulcanizing thin steel plates and thin rubber sheets. The bottom plate and the top plate are both steel plates. The bottom of the bottom plate and the top of the top plate are respectively installed with a lower pier and an upper pier, and the upper pier and the lower pier are both tied and installed with a first L-shaped steel bar, an outer steel bar, a first connecting steel bar, a second L-shaped steel bar, a second connecting steel bar and an embedded steel bar; the positioning assembly and the support assembly for constructing the seismic base for the prefabricated house building are also included; the positioning assembly is used to assist construction personnel in installing and positioning the embedded steel bars, and the positioning assembly is connected to the embedded steel bars; the support assembly is used to support and limit the seismic base main body, and the support assembly is respectively connected to the upper pier and the lower pier.

[0008] Optionally, the positioning assembly includes an embedded sleeve screwed onto the top of the embedded steel bar, a positioning plate is sleeved on the top of the embedded sleeve, a positioning sleeve corresponding to the position of the embedded sleeve is fixedly connected to the top of the positioning plate, and a fixing bolt is screwed into the positioning sleeve.

[0009] Optionally, a slot that matches the size of the top of the embedded sleeve is opened at the bottom of the positioning plate, a positioning block is fixedly connected to the top of the positioning plate, the positioning block is installed at the outer circumference of the slot, a weakening groove is opened at the connection position between the positioning block and the positioning plate, the positioning block is thinned at the position where the weakening groove is opened, and the two ends of the positioning block are not fixed to the positioning plate.

[0010] Optionally, a cross axis is provided on the positioning plate, and the positioning plate is a metal plate.

[0011] Optionally, the support assembly includes a lower support plate sleeved on the top of the lower pier, an upper support plate is inserted on the top of the lower support plate, there are four lower support plates and four upper support plates, and they are respectively located at four edge positions of the lower pier and the upper pier.

[0012] Optionally, a lower support block is symmetrically mounted on the top of the lower support plate, the lower support block is a triangular structure, and a snap-fit ​​groove is provided at the middle position of the lower support block.

[0013] Optionally, the bottom of the upper support plate is fixedly connected to an upper support block corresponding to the position of the lower support block, and a snap-in plate adapted to the profile of the snap-in groove is provided at the middle position of the upper support block. The lower support block and the upper support block are spliced ​​together to form a rectangular parallelepiped profile.

[0014] Optionally, the height of the cuboid formed by splicing the lower support block and the upper support block is consistent with the height of the buffer column.

[0015] Optionally, an inclined surface is provided on the inner wall of the lower support plate, and the inclined surface is inclined toward the center position of the buffer column.

[0016] Compared with the prior art, the present invention has at least the following beneficial effects:

[0017] In the above scheme, by setting a positioning component, when the construction workers insert the embedded sleeve into the slot, they can judge whether the embedded sleeve is fully inserted into the slot by observing whether the positioning block protrudes from the top of the positioning plate, and the construction workers can observe the protrusion of the positioning block to judge whether the embedded sleeve is vertically inserted into the slot. Through such a setting, not only the relative height between each embedded sleeve and the positioning plate can be judged, but also whether the embedded sleeve and the positioning plate are perpendicular to each other can be judged, thereby ensuring the accuracy of the installation of the embedded sleeve, improving the firmness of the installation of the seismic base main body and the accuracy of the installation process. After the construction workers screw the fixing bolt into the positioning sleeve, the fixing bolt will screw and fix the embedded sleeve. Such a setting can lock the embedded sleeve to the positioning plate, so that the construction workers can lock and fix the embedded steel bars conveniently, and there is no need for the construction workers to manually adjust and manually hold the embedded steel bars when fixing them, thereby improving the efficiency of fixing and the stability of the embedded steel bars during the fixing process.

[0018] By setting up the support assembly, when the seismic base body falls from top to bottom toward the lower pier, the lower support block can assist in guiding the seismic base body, and guide the seismic base body to the rectangular outline formed by the inner walls of the four lower support plates. When the seismic base body is close to the top of the lower pier, the inclined surface can finally position the seismic base body, thereby improving the accuracy of the seismic base body falling to the top of the lower pier. During the above operation, construction personnel do not need to manually adjust the falling position of the seismic base body, thereby improving the efficiency of the installation of the seismic base body and the accuracy of the installation process.

[0019] By setting up a support assembly, when the upper support block and the lower support block are spliced ​​together, the two can limit each other with the help of the clamping plate and the clamping groove, thereby achieving a fixing effect on the upper support plate. Since the four upper support plates are enclosed and sleeved on the outside of the top plate, the upper support plate can be used to achieve a limiting effect on the top plate, thereby improving the stability of the top plate during the construction of the upper pier; since the lower support block and the upper support block are spliced ​​together to form a rectangular parallelepiped outline, and the height of the rectangular parallelepiped is consistent with the height of the buffer column, when the upper support plate and the lower support plate are spliced ​​together, the buffer column can be supported and limited to prevent the buffer column from being deformed under the pressure of external force, thereby further improving the stability of the top plate.

[0020] According to the steel bar binding process provided in this application, space will be reserved between the steel bars for installing pre-embedded steel bars. The construction workers will first insert the pre-embedded steel bars into the steel bars of the lower pier from top to bottom. The pre-embedded steel bars will not be affected by the internal steel bar structure of the lower and upper piers during the insertion process, which improves the layout efficiency and installation convenience of the pre-embedded steel bars. Compared with the existing technology, the steel bar binding method provided in this application is more convenient for construction workers to install pre-embedded steel bars.

[0044] like Figures 1 to 6As shown, an embodiment of the present invention provides an earthquake-resistant base for assembled house buildings, including an earthquake-resistant base body, the earthquake-resistant base body including a bottom plate 9, a top plate 11 and a buffer column 10, the bottom plate 9 and the top plate 11 are fixedly connected to the bottom and top of the buffer column 10 respectively, the buffer column 10 is formed by overlapping and vulcanizing thin steel plates and thin rubber sheets, the bottom plate 9 and the top plate 11 are both steel plates, the bottom of the bottom plate 9 and the top of the top plate 11 are respectively installed with a lower pier 6 and an upper pier 12, the upper pier 12 and the lower pier 6 are tied and installed with a first L-shaped steel bar 1, an outer steel bar 101, a first connecting steel bar 102, a second L-shaped steel bar 103, a second connecting steel bar 104 and an embedded steel bar 2, in this application, Compared with the prior art, the binding of the internal steel bars of the upper pier 12 and the lower pier 6 is more convenient for construction workers to install the embedded steel bars 2. Since the binding process of the internal steel bars of the upper pier 12 and the lower pier 6 is the same, only the binding process of the internal steel bars of the lower pier 6 is described here, and the binding of the internal steel bars of the upper pier 12 is not repeated. Specifically, in the actual binding process, the construction workers first bind the first L-shaped steel bars 1 side by side at intervals according to the prefabricated size of the lower pier 6, wherein the short side of the first L-shaped steel bars 1 is located at the top of the lower pier 6, and then the outer steel bars 101 are sleeved from bottom to top on the outside of the first L-shaped steel bars 1, and the sleeve spacing between the outer steel bars 101 is consistent with the binding spacing between the first L-shaped steel bars 1 (such as Figure 2 As shown), after the outer steel bar 101 is set, the first connecting steel bar 102 is cross-tied between the two adjacent first L-shaped steel bars 1, and the first connecting steel bar 102 is tied to the top of the outer steel bar 101, and a group of first connecting steel bars 102 is set every layer between the outer steel bar 101 (as shown). Figure 3 As shown), after the first connecting steel bar 102 is tied, the second L-shaped steel bar 103 and the second connecting steel bar 104 are tied according to the tying process of the first L-shaped steel bar 1 and the first connecting steel bar 102 (as shown in FIG. Figure 4 and Figure 5 As shown), when the second connecting steel bar 104 is also tied, the tying operation of all the steel bars inside the lower pier 6 can be completed.

[0045] After the internal reinforcement of the lower pier 6 is tied, the construction workers can tie and fix the embedded reinforcement 2. Specifically, according to the above-mentioned process of tying the internal reinforcement of the lower pier 6, space for installing the embedded reinforcement 2 will be reserved between the reinforcements (such as Figure 6 As shown in the figure, the construction workers first insert the embedded steel bars 2 into the steel bars of the lower pier 6 from top to bottom, and then pre-fix the embedded steel bars 2 with the help of steel wire. The embedded steel bars 2 will not be affected by the internal steel bar structure of the lower pier 6 during the insertion process, thereby improving the layout efficiency and installation convenience of the embedded steel bars 2.

[0046] As an implementation method in this embodiment, Figures 6 to 10As shown, an earthquake-resistant base for prefabricated house construction also includes a positioning component and a support component for constructing the earthquake-resistant base for prefabricated house construction, the positioning component is used to assist construction workers in installing and positioning the embedded steel bars 2, and the positioning component is connected to the embedded steel bars 2; the positioning component includes an embedded sleeve 3 screwed to the top of the embedded steel bars 2, the top of the embedded sleeve 3 is sleeved with a positioning plate 4, a cross axis 405 is opened on the positioning plate 4, the positioning plate 4 is a metal plate, the top of the positioning plate 4 is fixedly connected to a positioning sleeve 401 corresponding to the position of the embedded sleeve 3, and a fixing bolt is screwed in the positioning sleeve 401 5. A slot 404 that matches the size of the top of the embedded sleeve 3 is provided at the bottom of the positioning plate 4. A positioning block 402 is fixedly connected to the top of the positioning plate 4. The positioning block 402 is installed at the outer circumference of the slot 404. A weakening groove 403 is provided at the connection position between the positioning block 402 and the positioning plate 4. The positioning block 402 is thinned at the position where the weakening groove 403 is provided. The two ends of the positioning block 402 are not fixed to the positioning plate 4. As mentioned above, after the construction workers pre-fix the embedded steel bars 2 to the internal steel bars of the lower pier 6 through steel wire, the construction workers can use the positioning assembly to lock and fix the embedded steel bars 2.

[0047] Specifically, first, the embedded sleeve 3 is screwed and fixed to the top of the embedded steel bar 2. The cross-sectional profile of the embedded sleeve 3 is a "T" shape, and the size of its top is larger than the size of the bottom. Then, the positioning plate 4 is sleeved on the top of the embedded sleeve 3 from top to bottom. Since the bottom of the positioning plate 4 is provided with a slot 404 that matches the size of the top of the embedded sleeve 3, the construction personnel can use the slot 404 to find the position of the embedded sleeve 3 to facilitate the splicing operation between the positioning plate 4 and the embedded sleeve 3. The positioning block 402 on the positioning plate 4 is installed on the outer circumference of the slot 404, and one side of the positioning block 402 is fixed to the positioning plate 4, and the rest of the positioning block 402 is non-contact with the positioning plate 4. The bottom of the positioning block 402 is a triangular structure and extends to the inside of the slot 404 (such as Figure 9 As shown), when the embedded sleeve 3 is inserted into the slot 404, the top of the embedded sleeve 3 will contact the bottom of the positioning block 402. Under the pressure of the embedded sleeve 3, the positioning block 402 is deformed at the position of the weakened groove 403 and avoids the embedded sleeve 3. At this time, the positioning block 402 will bend upward and protrude from the top of the positioning plate 4 (as shown). Figure 10As shown), through such an arrangement, when the construction personnel insert the embedded sleeve 3 into the slot 404, they can judge whether the embedded sleeve 3 is fully inserted into the slot 404 by observing whether the positioning block 402 protrudes from the top of the positioning plate 4. Since a plurality of positioning blocks 402 are arranged in a circumferentially equidistant array at the position of each slot 404, the construction personnel can observe the protrusion of each positioning block 402 to judge whether the embedded sleeve 3 is vertically inserted into the slot 404. Through such an arrangement, not only the relative height between each embedded sleeve 3 and the positioning plate 4 can be judged, but also whether the embedded sleeve 3 and the positioning plate 4 are perpendicular to each other can be judged, thereby ensuring the accuracy of the installation of the embedded sleeve 3, and improving the firmness of the installation of the anti-seismic base body and the accuracy of the installation process.

[0048] Furthermore, since the positioning sleeve 401 is concentric with the slot 404, when the construction worker screws the fixing bolt 5 into the positioning sleeve 401, the fixing bolt 5 extends along the positioning sleeve 401 into the embedded sleeve 3 and screws the embedded sleeve 3 to fix it (e.g., Figure 10 As shown), such a setting can lock and fix the embedded sleeve 3 on the positioning plate 4, so as to facilitate the construction personnel to lock and fix the embedded steel bar 2, and there is no need for the construction personnel to manually adjust and manually hold the embedded steel bar 2 when fixing the embedded steel bar 2, thereby improving the fixing efficiency and the stability of the embedded steel bar 2 during the fixing process.

[0049] In this embodiment, if Figures 11 to 14 As shown, the support assembly is used to support and limit the anti-seismic base body, and the support assembly is connected to the upper pier 12 and the lower pier 6 respectively. The support assembly includes a lower support plate 7 sleeved on the top of the lower pier 6, and the top of the lower support plate 7 is plugged with an upper support plate 8. There are four lower support plates 7 and four upper support plates 8, and they are respectively located at the four side line positions of the lower pier 6 and the upper pier 12. The top of the lower support plate 7 is symmetrically installed with a lower support block 701, which is a triangular structure. The inner wall of the lower support plate 7 is provided with Inclined surface 703 is inclined toward the center of the buffer column 10. When the anti-seismic base body is installed on the top of the lower pier 6, it is necessary to use a hoist to lift the anti-seismic base body from top to bottom onto the lower pier 6. At this stage, the position of the anti-seismic base body falling is mainly adjusted manually by construction personnel. This not only poses a safety hazard, but also has a low accuracy in the falling of the anti-seismic base body. In this application, a support assembly is provided to assist construction personnel in locating the falling position of the anti-seismic base body and improve the accuracy of the falling of the anti-seismic base body.

[0050] Specifically, the lower support plate 7 is sleeved on the four side line positions of the top of the lower pier 6. During the actual operation, the construction workers sleeve the lower support plate 7 on the lower pier 6 from the side of the lower pier 6. The four lower support plates 7 are independent of each other, and after each lower support plate 7 is sleeved, the construction workers can temporarily fix the lower support plate 7 with bolts to improve the firmness of the lower support plate 7. When the four lower support plates 7 are installed on the top of the lower pier 6, the inner walls of the four lower support plates 7 will enclose a rectangular outline, which is adapted to the size of the bottom plate 9 (such as Figure 11 As shown), since a lower support block 701 with a triangular outline is installed on the top of the lower support plate 7, and the triangular structure of the lower support block 701 is inclined toward the center position of the lower pier 6, when the seismic base body falls from top to bottom toward the lower pier 6, the lower support block 701 can be used to assist in guiding the seismic base body and guide the seismic base body into the rectangular outline formed by the inner walls of the four lower support plates 7. Since an inclined surface 703 is also provided on the bottom inner wall of the lower support plate 7, and the inclined surface 703 is inclined toward the center position of the buffer column 10, when the seismic base body approaches the top of the lower pier 6, the inclined surface 703 can be used to finally position the seismic base body, thereby improving the accuracy of the seismic base body falling to the top of the lower pier 6. During the above operation, the construction personnel do not need to manually adjust the falling position of the seismic base body, thereby improving the efficiency of the installation of the seismic base body and the accuracy of the installation process.

[0051] In this embodiment, if Figures 11 to 14 As shown, a snap-in groove 702 is provided at the middle position of the lower support block 701, and an upper support block 801 corresponding to the position of the lower support block 701 is fixedly connected to the bottom of the upper support plate 8, and a snap-in plate 802 adapted to the outline of the snap-in groove 702 is provided at the middle position of the upper support block 801. The lower support block 701 and the upper support block 801 are spliced ​​together to form a rectangular parallelepiped outline. The height of the rectangular parallelepiped formed by the lower support block 701 and the upper support block 801 is consistent with the height of the buffer column 10. When the anti-seismic base body is fixed to the lower After the top of the pier 6 is installed, the upper pier 12 needs to be installed on the top of the seismic base body. During the installation of the upper pier 12, in order to ensure the stability of the top plate 11, a limiting mechanism needs to be installed around the seismic base body to prevent the top plate 11 from shaking during the installation of the upper pier 12. The current limiting mechanism is mainly spliced ​​by bolts and steel plates. The operation is complicated and the efficiency is low during the assembly process. In this application, the support assembly can provide auxiliary support and limitation to the seismic base body to ensure the stability of the top plate 11 during the construction of the upper pier 12.

[0052] Specifically, the construction workers put the upper support plate 8 on the top plate 11 from top to bottom. During the upper support plate 8, the upper support block 801 will be spliced ​​together with the lower support block 701 (such as Figure 13As shown), since the contours of the clamping plate 802 and the clamping groove 702 match, when the upper support block 801 and the lower support block 701 are spliced ​​together, the two can limit each other with the help of the clamping plate 802 and the clamping groove 702, thereby achieving a fixing effect on the upper support plate 8. Since the four upper support plates 8 are enclosed and sleeved on the outside of the top plate 11, the upper support plate 8 can be used to achieve a limiting effect on the top plate 11. Since the lower support block 701 and the upper support block 801 are spliced ​​together to form The outline of the rectangle is consistent with the height of the buffer column 10. Therefore, when the upper support plate 8 and the lower support plate 7 are spliced ​​together, the buffer column 10 can be supported and limited to prevent the buffer column 10 from being deformed under the pressure of external force, thereby further improving the stability of the top plate 11. When the top plate 11 is limited by the upper support plate 8, the upper pier 12 can be constructed. The construction process of the upper pier 12 is consistent with the construction process of the lower pier 6, so it will not be repeated.

[0053] The working principle of the technical solution provided by the present invention is as follows:

[0054] When in use, the steel bars inside the lower pier 6 are first tied. The construction workers first tie the first L-shaped steel bars 1 side by side and at intervals according to the prefabricated size of the lower pier 6, wherein the short side of the first L-shaped steel bars 1 is located at the top of the lower pier 6, and then the outer steel bars 101 are sleeved from bottom to top on the outside of the first L-shaped steel bars 1. The sleeve spacing between the outer steel bars 101 is consistent with the binding spacing between the first L-shaped steel bars 1. When the outer steel bars 101 are sleeved, the first connecting steel bars 102 are cross-tied between the two adjacent first L-shaped steel bars 1. The first connecting steel bars 102 are tied to the top of the outer steel bars 101, and a group is set for each layer between the outer steel bars 101. After the first connecting steel bars 102 are tied, the tying work of the second L-shaped steel bars 103 and the second connecting steel bars 104 is completed according to the tying process of the first L-shaped steel bars 1 and the first connecting steel bars 102. When the second connecting steel bars 104 are also tied, the tying operation of all the steel bars inside the lower pier 6 can be completed.

[0055] Then the embedded steel bars 2 are installed and fixed. The construction workers first insert the embedded steel bars 2 into the steel bars of the lower pier 6 from top to bottom, and then pre-fix the embedded steel bars 2 with the help of steel wire. Subsequently, the construction workers screw the embedded sleeve 3 to the top of the embedded steel bars 2, and then put the positioning plate 4 from top to bottom on the top of the embedded sleeve 3. Since the bottom of the positioning plate 4 is provided with a slot 404 that matches the size of the top of the embedded sleeve 3, the construction workers can use the slot 404 to find the position of the embedded sleeve 3 to facilitate the splicing operation between the positioning plate 4 and the embedded sleeve 3. After the construction workers screw the fixing bolt 5 into the positioning sleeve 401, the fixing bolt 5 will extend along the positioning sleeve 401 into the embedded sleeve 3, and screw the embedded sleeve 3 to fix it through threads.

[0056] After the embedded steel bars 2 are fixed, concrete is poured on the lower pier 6. When the concrete is air-dried and fixed, the seismic base body is installed on the top of the lower pier 6. The construction workers put the lower support plate 7 on the lower pier 6 from the side of the lower pier 6, and then temporarily fix the lower support plate 7 with bolts to improve the firmness of the lower support plate 7. When the seismic base body falls from top to bottom toward the lower pier 6, the lower support block 701 can be used to assist in guiding the seismic base body, and guide the seismic base body to the rectangular outline formed by the inner walls of the four lower support plates 7, and then lock the seismic base body to the top of the lower pier 6 with the fixing bolts 5.

[0057] After the top plate 11 is limited by the upper support plate 8, the upper pier 12 can be constructed. The construction process is the same as that of the lower pier 6. First, tie the steel bars and then pour concrete.
