Technical Field

[0001] The invention relates to the technical field of building construction, and in particular to a door opening formwork structure which is convenient for slipform construction. Background Art

[0002] Many buildings now use slipform construction technology, which can improve construction efficiency. For some buildings with doors and windows, it is necessary to install door formwork between the side panels of the slipform during slipform construction, and then pour concrete. When the concrete hardens and the slipform rises to the upper side of the door formwork, the door formwork can be taken out. Currently, common door formworks are directly welded with steel plates to form a rectangular frame structure. This method requires welding work on the construction site, which is inconvenient to operate. At the same time, after use, it is very inconvenient to carry due to its large size. Summary of the invention

[0003] In order to solve the above problems existing in the prior art, the present invention provides a door opening formwork structure which is modularly assembled, easy to assemble and disassemble, and easy to carry and convenient for sliding formwork construction.

[0005] By adopting the above technical solution: the formwork frame is used to form the door opening space, the pressure-bearing bracket in the formwork frame is used to enhance the overall compressive resistance, both ends of the side reinforcement beam in the formwork frame are supported and bear pressure through abutment, and the adjacent formworks are directly detachably connected, which makes the disassembly and installation of the upper formwork, lower formwork and side formwork more convenient, and they can be disassembled and transported during transportation, and can be quickly assembled and used when moved to the construction site.

[0006] Preferably, the upper reinforcing beam, the lower reinforcing beam and the side reinforcing beam are all made of square tubes. The upper reinforcing beam is welded to the upper template, the lower reinforcing beam is welded and fixed to the lower template, and the side reinforcing beam is welded and fixed to the side template; the two ends of the upper reinforcing beam are respectively abutted against the inner side of the side template, and the two ends of the lower reinforcing beam are respectively abutted against the inner side of the side template. The square tube structure has high strength and can be directly purchased, with low cost and convenient processing; the upper reinforcing beam and the lower reinforcing beam are abutted against the side template to increase the pressure-bearing performance of the side template.

[0007] Preferably, the pressure-bearing bracket is arranged at the center of the template frame, and both ends of the side reinforcing beam are fixed with stoppers protruding from the end of the side reinforcing beam, and a stopper groove is formed between the two stoppers at the same end of the side reinforcing beam; the two ends of the upper reinforcing beam are inserted into the stopper groove at the upper end of the side reinforcing beam, and the two ends of the lower reinforcing beam are inserted into the stopper groove at the lower end of the side reinforcing beam. The pressure-bearing bracket is arranged in the middle position, so that the template frame is more balanced and stable under pressure; the stopper groove is inserted into the lower reinforcing beam and the upper reinforcing beam, which makes the assembly process more convenient on the one hand, and can bear the pressure from the side on the other hand to prevent the templates from being misaligned.

[0008] Preferably, the connection assembly includes two vertically distributed connection sleeves and a connection rod, the two connection sleeves are respectively fixed on two adjacent templates, the connection rod is L-shaped, the two ends of the connection rod are respectively inserted into the two connection sleeves to form a plug-in connection, and the side of the connection sleeve is provided with a fastener for locking the connection rod. After one end of the connection rod is inserted into the connection sleeve and fixed by the fastener, the other set of connection sleeves can be directly inserted into the other end of the connection rod to achieve vertical connection.

[0009] Preferably, the connection components between any two adjacent templates are configured as two groups. Providing two groups of connection components further improves the connection stability.

[0010] Preferably, a reinforcement bracket is provided inside the pressure-bearing bracket, and the reinforcement bracket is formed by connecting a number of support beams distributed transversely and longitudinally, wherein the two ends of the support beams distributed transversely are respectively connected to the side reinforcement beams, and the two ends of the support beams distributed longitudinally are respectively connected to the upper reinforcement beam and the lower reinforcement beam. The reinforcement bracket is used to further increase the compression resistance between the side templates, especially for supporting door openings with larger internal spaces.

[0011] Preferably, the support beams are made of square tubes, and both sides of the outer ends of the support beams are provided with limit blocks, and a slot is formed between the two limit blocks; a reinforcing component is provided at the connection of the mutually perpendicular support beams.

The cross limit groove on the connection seat is locked by the locking sleeve after being stuck in the connection of the support beam; when it needs to be disassembled, the locking sleeve can be loosened to remove the reinforcement beam; when it needs to be disassembled after slipform casting, if the wall of some buildings is thick, the pressure support can be removed first (to reduce the pressure between the formwork frame and the concrete, thereby reducing the friction), and then the whole can be pulled out, making disassembly more labor-saving.

[0013] Preferably, it also includes an embedded component for positioning the formwork frame, the embedded component includes an embedded seat, a screw sleeve fixed on the embedded seat, a screw is arranged in the screw sleeve; the lower formwork is provided with a plurality of connection holes, the screw passes through the connection holes and is fastened by nuts. During the slipform construction process, the embedded parts are buried in the concrete, and when the formwork frame is installed, the screw is inserted into the connection hole, the lower end of the screw is connected to the screw sleeve, and finally the formwork frame is connected and positioned with the screw by the nut; if the formwork frame needs to be dismantled, the nut is loosened, the screw is removed, and the formwork device can be pulled out as a whole through the equipment.

When the thickness of the wall of the slipform construction is large, two or more groups of formwork frame groups can be used in combination to meet the wall thickness requirements (for example, when pouring a dam, the thickness is very large, and multiple groups can be used in combination); at the same time, when disassembling, the straight rod can be separated from the sleeve, and each group of formwork frame groups can be pulled out of the concrete separately to reduce the resistance of pulling out, making disassembly more convenient.

[0015] Therefore, the present invention has the beneficial effects of modular assembly, convenient assembly and disassembly, and convenient transportation. When pouring some thick concrete, multiple formwork frame groups can be used in combination and then disassembled separately after use. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] In order to make the technical problems, technical solutions and beneficial technical effects to be solved by the present invention more clearly understood, the present invention will be further described in detail below in conjunction with the accompanying drawings and multiple exemplary embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention, rather than to limit the scope of protection of the present invention.

[0027] It should be understood that, in this document, the expressions "first", "second", etc. are used for descriptive purposes only and should not be understood as indicating or implying relative importance, nor should they be understood as implicitly indicating the number of technical features indicated. Features defined as "first" or "second" may explicitly or implicitly indicate that at least one of the features is included.

[0028] like Figure 1-Figure 7 A door opening formwork structure that is convenient for slipform construction is shown, including at least one group of formwork frame groups 1 and embedded components 50 for fixing the formwork frame groups; the formwork frame group includes a formwork frame 10 and a pressure-bearing support 20 arranged in the formwork frame 10; the formwork frame 10 includes a lower formwork 11, an upper formwork 12, and two side formworks 13 arranged between the ends of the upper formwork 12 and the lower formwork 11; the pressure-bearing support 20 is a rectangular structure, including a lower reinforcing beam 21 fixedly arranged on the upper side of the lower formwork 11, an upper reinforcing beam 22 fixedly arranged on the lower side of the upper formwork 12, and a side reinforcing beam 23 fixedly arranged on the inner side of the side formwork 13, the lower end of the side reinforcing beam 23 abuts against the upper side of the end of the lower reinforcing beam 21, and the upper end of the side reinforcing beam 23 abuts against the lower side of the end of the upper reinforcing beam 22; a connecting component 30 is provided between any two adjacent formworks in the formwork frame 10, and the two adjacent formworks are detachably connected through the connecting component 30.

[0029] The upper reinforcing beam 22, the lower reinforcing beam 21, and the side reinforcing beam 23 are all made of square tubes. The upper reinforcing beam 22 is welded to the upper template 12, the lower reinforcing beam 21 is welded to the lower template 11, and the side reinforcing beam 23 is welded to the side template 13; the two ends of the upper reinforcing beam 22 are respectively in contact with the inner side surface of the side template 13, and the two ends of the lower reinforcing beam 21 are respectively in contact with the inner side surface of the side template 13. The lower template 11, the upper template 12, and the two side templates 13 can be made of metal plates such as aluminum alloy plates, steel plates, and iron plates according to the actual pressure-bearing state during use.

[0030] The pressure-bearing bracket 20 is arranged at the center of the template frame 10. The two ends of the side reinforcing beam 23 are fixed with stoppers 230 protruding from the end of the side reinforcing beam 23. A stopper groove 231 is formed between the two stoppers 230 at the same end of the side reinforcing beam 23. The two ends of the upper reinforcing beam 22 are inserted into the stopper groove 231 at the upper end of the side reinforcing beam 23, and the two ends of the lower reinforcing beam 21 are inserted into the stopper groove 231 at the lower end of the side reinforcing beam 23. In some embodiments, the stopper 230 is also made of a square tube, that is, the square tube is cut into a preset length and then directly welded to the two end sides of the side reinforcing beam 23. In order to further increase the connection stability between the stopper and the side reinforcing beam, the stopper and the side reinforcing beam are welded and then fastened by bolts (or screws) and nuts.

[0031] like Figure 4 and Figure 5 As shown, the connection assembly 30 includes two vertically distributed connection sleeves 31 and a connection rod 32. The two connection sleeves 31 are respectively fixed on two adjacent templates. The connection rod 32 is L-shaped. The two ends of the connection rod 32 are respectively inserted into the two connection sleeves 31 to form a plug-in connection. The side of the connection sleeve 31 is provided with a fastener 33 for locking the connection rod 32. In some embodiments, the connection assembly 30 between any two adjacent templates is configured as two groups, and the connection sleeve is also made of square tubes, that is, the square tube is cut into the required length and then welded on the template. In order to further improve the convenience of assembly, the cross section of the connection rod adopts a rectangular structure corresponding to the inner hole of the connection sleeve, so that after one end of the connection rod is inserted into the connection sleeve, the direction of the other end of the connection rod remains stable.

[0032] like Figure 6 and Figure 7As shown, a reinforcement bracket 40 is provided inside the pressure-bearing bracket 20, and the reinforcement bracket 40 is formed by connecting a number of support beams 400 distributed transversely and longitudinally, wherein the two ends of the support beams 400 distributed transversely are respectively connected with the side reinforcing beams 23, and the two ends of the support beams 400 distributed longitudinally can be respectively connected with the upper reinforcing beam 22 and the lower reinforcing beam 21. The support beams 400 are all made of square tubes, and both sides of the outer ends of the support beams 400 are provided with limit blocks 41, and a slot 410 is formed between the two limit blocks 41; and a reinforcement component 42 is provided at the connection of the mutually perpendicular support beams 400. The slot is clamped on the reinforcing beam to increase the connection stability between the reinforcement bracket and the pressure-bearing. In some embodiments, the limit block is also made of square tubes, that is, the square tube is cut into a preset length and then installed at the end of the support beam by a through bolt. After the limit slot is clamped on the reinforcing beam, it can also be further connected to the reinforcing beam by bolts and nuts.

[0033] The reinforcement assembly 42 includes a connection seat 420 and a locking sleeve 421. The end surface of the connection seat 420 is provided with a cross limit groove 422. The support beam 400 is inserted into the cross limit groove 422. The locking sleeve 421 is threadedly connected to the connection seat 420. The mutually perpendicular support beams are connected together by the reinforcement assembly. After removing the reinforcement assembly, the entire reinforcement bracket can be removed from the pressure bracket, so that when the formwork frame group is taken out from the concrete, the pressure of the concrete on the outer wall of the formwork frame group can be reduced, which is convenient for smooth disassembly.

[0034] like Figure 1 and Figure 5 As shown, the template frame 10 also includes an embedded component 50 for positioning, the embedded component 50 includes an embedded seat 51, a screw sleeve 52 fixed on the embedded seat 51, and a screw 53 is arranged in the screw sleeve 52; the lower template 11 is provided with a plurality of connection holes 110, and the screw 53 passes through the connection holes and is fastened by nuts. The embedded component facilitates the positioning of the formwork device. When the formwork device needs to be taken out after use, the nuts and screws are first removed, and then the whole is pulled out of the door opening to one side through the traction equipment.

[0035] like Figure 8 and Fig. 9 As shown, the formwork frame group 1 is configured into two groups, and the upper side of the lower formwork 11 and the lower side of the upper formwork 12 are fixed with a sleeve 60 perpendicular to the plane where the formwork frame 10 is located, and the side of the sleeve 60 is provided with a locking bolt 61, and a straight rod 62 is provided between the two groups of formwork frame groups 1, and the two ends of the straight rod 62 are respectively inserted into the sleeve 60 and then locked by the locking bolt 61. When the wall is thick (such as dam slipform construction), two or more formwork frame groups can be used in combination, so that each formwork frame group can be disassembled separately during disassembly, reducing disassembly resistance and making disassembly more convenient.

[0036] like Fig.10As shown, during the construction of some curved walls, such as the slipform construction of a cylindrical granary, in order to adapt to the curved surface of the wall, the edges of the upper and lower templates can be set to be curved to adapt to the curved wall.

[0037] In conjunction with the accompanying drawings, the principles of the present invention are as follows: Figure 1 As shown, the lower template is connected and positioned with the embedded parts; the template frame is used to construct the door opening space, and the pressure-bearing bracket in the template frame is used to enhance the overall compressive resistance. Both ends of the side reinforcement beam in the template frame are supported and bear pressure through abutment, and the side reinforcement beams are further reinforced and supported by reinforcement brackets. The overall support is stable. Based on this structure, any rectangular door opening can be supported by adjusting the size; adjacent templates are directly detachable and connected. After a support structure is disassembled, it becomes four templates (with connecting sleeves and reinforcement beams), reinforcement brackets, and several connecting rods. There are fewer parts and a high degree of standardization, so installation, disassembly, and transportation are more convenient; a large number of components are made of square tubes. For example, the upper reinforcement beam, the lower reinforcement beam, the side reinforcement beam, the connecting sleeve, the limit piece, the limit block, the sleeve, etc. can all be made by cutting square tubes, which is simple to obtain materials and low in cost.

[0038] In the description of the present invention, it is necessary to understand that the directions or positional relationships indicated by up, down, left, right, inside, outside, one end, the other end, etc. are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the purpose of more clearly describing the technical solution of the present invention, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific orientation, and cannot be understood as a limitation of the present invention.

[0039] Although specific embodiments of the present invention are described in detail herein, they are provided for the purpose of explanation only and should not be considered to limit the scope of the present invention. Various substitutions, changes and modifications may be conceived without departing from the spirit and scope of the present invention.
