Description

Technical Field

[0001] The invention relates to the technical field of precast concrete frame structures, in particular to a precast concrete frame construction structure. Background Art

[0002] Since my country's reform and opening up, infrastructure construction has been greatly improved, especially the application of precast concrete frame structure, which makes some wall structures no longer need to be cast and solidified on site. Precast concrete is cast and solidified elsewhere. The existing wall structures prepared by precast concrete are all honeycomb wall structures. The honeycomb wall structure is a vertical through hole in the whole wall, making the wall hollow. This kind of wall not only has strong supporting strength, but also has the advantages of heat insulation, sound insulation, and warmth preservation.

[0003] The precast concrete frame construction structure is connected and assembled by traditional connectors such as bolts and nuts. A variety of tools are needed during the installation and disassembly process, which makes it very inefficient. In addition, the through holes in the honeycomb wall are formed by long columns. During the pouring process, the long columns are in direct contact with the concrete, resulting in solidification between the long columns and the concrete, which makes it difficult to pull out the long columns. The long columns have poor stability in the concrete and are very easy to fall over in the concrete. Therefore, it is necessary to set a clamping circular plate to fix the long columns. In order to solve the above problems, we propose a precast concrete frame construction structure. Summary of the invention

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

[0017] The invention releases the clamping positioning of the connecting long plate by the pushing block, and then pulls the pull plate outward, so that the pulling plate drives the movable ring plate on one side to move horizontally and causes the driving pushing block to disengage from the outer clamping groove, wherein the movable column and the movable ring plate are welded and connected, and the pulling plate and the second spring move outwardly horizontally to drive the movable ring plate to squeeze the second spring extension elastic force. At this time, the upper movable round block and the connecting type long plate are pushed upward by the upward extension elastic force of the third spring, and the connecting type long plate drives the connecting plate strips and the plug-in column on one side to move upward, so that the two plug-in columns can be automatically inserted into the insertion holes on the first connecting block and the second connecting block. In the above settings and operations, the user only needs to press the pressing column downward to realize the disassembly of the first connecting frame and the second connecting frame, and the user only needs to pull the pulling plate on the outer side of the outer cylindrical tube to realize the matching connection of the integral pressing column and the connecting type long plate, so that there is no need for traditional connecting parts such as bolts and nuts, thereby making the operation of assembling the overall prefabricated frame structure simple and convenient, and improving the efficiency of assembly;

[0018] The user rotates the matching circular plate at the upper end of the long column and the overall outer circular plate, wherein four trapezoidal grooves are fixedly set around the upper and lower ends of the long column, and the inclined surfaces set on both sides of the inner clamping block are movably matched with the inclined surfaces on both sides of the trapezoidal grooves. Then, when the inner clamping block rotates before the outer circular plate, the long column can squeeze the inner clamping block into the outer circular plate, and the first spring is contracted by the squeezing activity of the inner clamping block. This setting and operation can make the clamping circular plate quickly detach from the long column, and then the overall long column is also rotated, so that the long column and the clamping circular plate at the lower end are rotated and detached. Since the film wrapped on the surface of the long column is smooth with the long column, the long column can be pulled out of the hole formed by the concrete, and the film has viscosity with the concrete, so that it remains in the hole of the concrete after solidification. The setting of the wrapping film further improves the efficiency of pulling the long column out of the concrete, so that the overall device can be quickly disassembled and the next concrete pouring prefabrication can be carried out.

When the overall first connecting frame 1 and the second connecting frame 2 are disassembled, the lower orders of the first connecting frame 1 and the second connecting frame 2 can be first horizontally removed from the long slots 15 in the bottom support frame 3.

[0032] The setting of the connecting strip 16 makes the T-shaped inserts 17 at the front and rear ends thereof respectively inserted into the T-shaped slots 18 on the first connecting frame 1 and the second connecting frame 2, which improves the fixed connection performance of the upper ends of the first connecting frame 1 and the second connecting frame 2, by welding the first connecting block 13 on both sides of the lower end of the second connecting frame 2, welding the second connecting block 14 on both sides of the lower end of the first connecting frame 1, and fixing the bottom plate 12 on both sides of the bottom end of the bottom support frame 3, and the front and rear sides of the bottom plate 12 are provided with matching positioning mechanisms 6, and the upper support between the two matching positioning mechanisms 6 is provided with a connecting bracket mechanism 7, and the connecting bracket mechanism 7 is supported at the upper end of the bottom plate 12.

[0033] By setting a pressing column 701 component in the connecting bracket mechanism 7, a connecting long plate 702 is welded to the lower part of the pressing column 701, and vertical plates are welded to both ends of the connecting long plate 702. External card slots 703 are penetrated on the vertical plates. Upper movable round blocks 706 are welded to both front and rear sides of the lower end of the connecting long plate 702. The lower end of the upper movable round block 706 is connected to a third spring 704. The surrounding of the third spring 704 is matched with a supporting cylinder 705. The front of the supporting cylinder 705 is welded to the lower end of the connecting long plate 702. Square through holes 709 are provided on both sides of the rear portion. The width of the connecting long plate 702 is slightly smaller than the width of the square through hole 709. The second connecting block 14 and the first connecting block 13 are both provided with plug-in holes. A connecting strip 707 is welded on one side of the connecting long plate 702. Plug-in columns 708 are welded on the front and rear sides of the upper end of the connecting strip 707. The two plug-in columns 708 are respectively inserted into the plug-in holes. The setting of the plug-in columns 708 greatly improves the connection performance between the first connecting block 13 and the second connecting block 14.

[0034] By setting an outer cylindrical tube 601 component in the matching positioning mechanism 6, wherein a second spring 603 is connected to the outer cylindrical tube 601, a movable ring plate 606 is connected to one side of the second spring 603, a push block 602 is welded to one end of the movable ring plate 606, a movable column 604 penetrates and is movable inside the outer cylindrical tube 601, a pull plate 605 is welded to the outer end of the movable column 604, and an outer circular plate 501 is set in the clamping circular plate 5, an installation cavity is fixedly set around the inner side of the outer circular plate 501, a first spring 502 is connected to the inner side of the first spring 502, and an inner clamping block 503 is connected to one side of the first spring 502, wherein the setting of the installation cavity enables the inner clamping block 503 to only move laterally into the trapezoidal groove 11.

[0035] When in use, firstly, the first connecting block 13 at the lower end of the second connecting frame 2 and the second connecting block 14 at the lower end of the first connecting frame 1 are vertically plugged and connected, and by providing a groove structure at the rear end of the first connecting block 13 and a convex block structure at the front end of the second connecting block 14, the groove on the first connecting block 13 and the convex block on the second connecting block 14 are vertically plugged and matched, and since the rear end of the connecting plate 9 at the upper end of the main end plate 10 on the front side is welded with the T-shaped plug plate 4, and the front end of the connecting plate 9 at the upper end of the main end plate 10 on the rear side is provided with a T-shaped slot, the T-shaped plug plate 4 on the front connecting plate 9 and the T-shaped slot on the rear connecting plate 9 are plugged and matched, and the above settings and operations first match and connect the entire second connecting frame 2;

[0036] Then, a connecting bracket mechanism 7 is supported and arranged at the upper end of the bottom plate 12, wherein a third spring 704 is connected and arranged inside the supporting cylinder 705. The upward stretching elastic force of the third spring 704 pushes the two upper movable round blocks 706 upward. When the upper movable round blocks 706 move upward, the integral connecting long plate 702 and the connecting strip 707 are pushed upward, so that the two plug-in columns 708 at the upper ends of the connecting strip 707 are respectively inserted into the insertion holes on the first connecting block 13 and the second connecting block 14. This arrangement greatly improves the connection performance between the first connecting block 13 and the second connecting block 14, thereby further improving the fixed connectivity between the integral first connecting frame 1 and the second connecting frame 2.

[0037] Then, the film is wrapped around the surface of the long column 19, and the film and the long column 19 have high sliding properties. By clamping the clamping circular plate 5 at the upper and lower ends of the long column 19, the clamping circular plate 5 can fix the film wrapped on the surface of the long column 19 to prevent the film from detaching from the surface of the long column 19. The inner clamping block 503 is connected to the inner side of the outer circular plate 501 through the first spring 502, wherein the lower end of the inner clamping block 503 is provided with an inclined surface, and the upper and lower ends of the long column 19 are provided with annular chamfers around them. The inclined surface at the lower end of the inner clamping block 503 and the annular chamfers around the upper end of the long column 19 are movably matched, which greatly improves the assembly activity between the overall outer circular plate 501 and the long column 19. The stretching elastic force of the first spring 502 pushes the inner clamping block 503 toward the inner side of the long column 19, so that the overall inner clamping block 503 is clamped in the trapezoidal groove 11 on the long column 19.

[0038] By arranging three bottom matching grooves 21 at the bottom ends of the first connecting frame 1 and the second connecting frame 2, and a through hole is penetrated through the upper end of the connecting plate 9, the long column 19 and the clamping circular plate 5 at the lower end thereof are penetrated through the through hole on the connecting plate 9 and are fitted in the bottom matching groove 21, and the clamping circular plate 5 at the upper end of the long column 19 is fitted in the through hole on the connecting plate 9. This operation can greatly improve the fixing performance of the overall long column 19 and the clamping circular plate 5 as a whole in the first connecting frame 1 and the second connecting frame 2. The diameter of the matching circular plate 20 is larger than the diameter of the through hole, so that the matching circular plate 20 is located at the upper end of the overall connecting plate 9. This arrangement facilitates the user to pull the overall matching circular plate 20 upward from the connecting plate 9;

[0039] Finally, concrete is poured into the first connecting frame 1 and the second connecting frame 2. The long column 19 blocks the first connecting frame 1 and the second connecting frame 2 so that a through hole is formed in the concrete, which passes through the first connecting frame 1 and the second connecting frame 2, thereby forming a honeycomb concrete wall structure.

[0040] After the concrete in the first connecting frame 1 and the second connecting frame 2 is solidified, the whole prefabricated frame needs to be disassembled. At this time, the user manually presses the pressing column 701 downward, so that the pressing column 701 drives the connecting strip 707 and the two plug-in columns 708 on one side to move downward, so that the two plug-in columns 708 can be disengaged from the insertion holes in the first connecting block 13 or the second connecting block 14, so that the connection between the first connecting block 13 and the second connecting block 14 is separated, wherein the downwardly movable connecting long plate 702 drives the two upper movable round blocks 706 at the lower end to move downward and squeeze the two third springs 704, thereby overcoming the stretching elastic force of the two third springs 704, and the connecting long plate 702 drives the front and rear ends downward or The vertical plate moves downward, so that the outer card slot 703 on the vertical plate can move downward. Since the upper end of one side of the push block 602 is provided with an inclined surface, and the end corners of the lower ends of both sides of the connecting long plate 702 are provided with inclined angles, the inclined angle on the connecting long plate 702 that moves downward and the inclined surface on the push block 602 can be coordinated, so that the entire connecting long plate 702 moves downward and the push block 602 is pushed horizontally to one side at the same time. Finally, the push block 602 is pushed by the extension elastic force of the second spring 603 inside the outer cylindrical tube 601 and is clamped in the outer card slot 703 on the vertical plate. Through this arrangement, the connecting long plate 702 can be fixed to prevent the connecting long plate 702 from being pushed upward by the extension elastic force of the third spring 704 at the lower end.

[0041] If the push block 602 is released from the clamping positioning of the connecting long plate 702, the pull plate 605 is pulled outward, so that the pull plate 605 drives the movable ring plate 606 on one side to move horizontally and drives the push block 602 to disengage from the outer clamping groove 703, wherein the movable column 604 and the movable ring plate 606 are welded and connected, and the pull plate 605 and the second spring 603 move horizontally outward to drive the movable ring plate 606 to squeeze the elastic force of the second spring 603. At this time, the upper movable round block 706 and the connecting long plate 702 are pushed upward by the elastic force of the third spring 704, and the connecting long plate 702 drives the connecting plate strip 707 and the plug-in column 708 on one side to move upward, so that the two plug-in columns 708 can be automatically inserted into the insertion holes on the first connecting block 13 and the second connecting block 14;

[0042] In the above settings and operations, the user only needs to press downwards on the pressing column 701 to achieve the disassembly of the first connecting frame 1 and the second connecting frame 2, and the user only needs to pull the pull plate 605 on the outside of the outer cylindrical tube 601 to achieve the matching connection between the overall pressing column 701 and the connecting long plate 702, without the need for traditional bolts, nuts and other connectors, thereby making the assembly operation of the overall prefabricated frame structure simple and convenient, and improving the efficiency of assembly.

[0043] The user rotates the matching circular plate 20 at the upper end of the long column 19 and the integral outer circular plate 501, wherein four trapezoidal grooves 11 are fixedly arranged around the upper and lower ends of the long column 19, and the inclined surfaces arranged on both sides of the inner clamping block 503 and the inclined surfaces on both sides of the trapezoidal grooves 11 are movably matched. Then, when the inner clamping block 503 rotates first on the outer circular plate 501, the long column 19 can squeeze the inner clamping block 503 into the outer circular plate 501, and the first spring 502 is squeezed by the squeezing activity of the inner clamping block 503. This setting and operation can make the clamping circular plate 5 is quickly separated from the long column 19, and then the whole long column 19 is also rotated, so that the long column 19 and the clamping circular plate 5 at the lower end are rotated and separated. Since the film wrapped on the surface of the long column 19 is smooth with the long column 19, the long column 19 can be pulled out from the hole formed in the concrete, and the film is sticky with the concrete, so that it remains in the hole of the solidified concrete. The setting of the wrapping film further improves the efficiency of pulling the long column 19 out of the concrete, so that the whole device can be quickly disassembled and the next concrete pouring prefabrication can be carried out.

[0044] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention. Any reference numeral in a claim should not be considered as limiting the claim to which it relates.
