Description

Technical Field

[0001] This utility model relates to the field of building construction, and in particular to an ultra-thick shear wall formwork support structure. Background Technology

[0002] Construction formwork is a temporary support structure, manufactured according to design requirements, to shape concrete structures and components according to specified positions and geometric dimensions, maintain their correct position, and bear the self-weight of the formwork and external loads acting on it. With the further development of national medical infrastructure construction, the application of special medical rooms with ultra-large cross-section shear wall structures in construction projects is gradually increasing. In this type of structure, ultra-large cross-section concrete components are mainly used to shield various radiations generated by special equipment in medical rooms. During construction, due to the excessive thickness of the shear wall, the lateral force of the concrete shear wall is too large. If only tie bolts are used to reinforce the wall formwork, on the one hand, the number of tie bolts used will further increase, and on the other hand, the strength of the tie bolts will be insufficient due to their excessive length. Therefore, the stability of the shear wall formwork and construction safety cannot be guaranteed.

[0003] A formwork reinforcement device for adjustable ultra-thick shear walls, disclosed in Chinese Utility Model Patent Application Publication CN 216239766 U, includes a fixing plate bolted to the bottom of the formwork surface. A connecting plate for fastening is clamped to the inner wall of the fixing plate. A limiting frame for positioning is fixedly connected to the bottom of the formwork surface. A locking block is fixedly connected to the upper surface of the connecting plate, and a detachable diagonal brace is inserted into the inner wall of the locking block. This adjustable ultra-thick shear wall formwork reinforcement device, through the arrangement of the formwork, fixing plate, connecting plate, diagonal brace, and tightening column, can fix the formwork, fastening the connecting plate inside the fixing plate. The diagonal brace provides good support, preventing excessive concrete at the top of the formwork from cracking. Construction workers can tighten the tightening column.

[0004] However, the adjustable ultra-thick shear wall formwork reinforcement device is inconvenient to install, and the diagonal braces and horizontal columns provide limited reaction force during use, and the strength of the tongue-and-groove connection between the formwork cannot be guaranteed. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model provides an ultra-thick shear wall formwork support structure.

[0006] The technical solution includes two templates, with several vertical wooden blocks set on the side of the two templates that are far apart from each other, and several steel supports set on the side of the two templates that are far apart from each other, with several square steel pipes connecting adjacent steel supports.

[0007] The two opposing steel supports are connected by a number of water-stop bolts, which pass through the two templates and the corresponding timber.

[0008] The steel support is fixed to the foundation slab concrete by anchor bolts.

[0009] Preferably, the steel support is in the shape of a right triangle, including a vertical pole and a horizontal base pole. The pole and the base pole are connected by an inclined brace. An inclined web member is fixedly installed in the middle of the inclined brace. The inclined web member is fixedly connected to the connection between the base pole and the pole.

[0010] The upright is provided with several supporting angle steels and steel support plates, and the two ends of the square steel tube are respectively inserted into the supporting angle steels and steel support plates of two adjacent steel supports.

[0011] Preferably, two supporting angle steels are fixedly installed at the upper and lower ends of the upright, and the two supporting angle steels are symmetrically arranged on both sides of the upright.

[0012] Preferably, a steel support plate is fixedly installed in the middle of the upright, the steel support plate is "L" shaped, and a slot is provided in the middle of the horizontal part of the steel support plate, and the upright of the steel bracket is located in the slot;

[0013] A positioning hole is provided in the middle of the vertical part of the steel support plate, the positioning hole passes through the upright, and the water-stop screw passes through the positioning hole.

[0014] Preferably, two mounting plates are provided at each end of the base rod, and the two mounting plates are symmetrically arranged on both sides of the base rod. Each mounting plate has a mounting hole for inserting anchor bolts.

[0015] The beneficial effects of the technical solution provided by this utility model embodiment are as follows: by using anchor bolts to fix the steel support, the spatial rigidity of the formwork support is increased, and the use of square steel pipes provides sufficient reaction force to support the formwork; the water-stop tie rods mainly play a certain degree of fixing and tensioning role; compared with traditional shear walls that rely solely on the tension of tie bolts to resist the extrusion force of concrete on the formwork; the use of triangular steel supports to provide sufficient reaction force reduces the use of a large number of tie rods, and the square steel pipes, as crossbars, only need to be inserted into the supporting angle steel or angle steel pads of the steel support without fixing, further facilitating the formwork support construction.

[0026] Example 1

[0027] See Figures 1 to 5 This utility model provides an ultra-thick shear wall formwork support structure, including two formworks 1, with several vertical wooden blocks 2 set on the side of the two formworks 1 that are far apart from each other, and several steel supports 3 set on the side of the two formworks 1 that are far apart from each other, and several square steel pipes 4 connecting adjacent steel supports 3.

[0028] Two opposing steel supports 3 are connected by several water-stop bolts 5, which pass through the two templates 1 and the corresponding wooden blocks 2;

[0029] The steel support 3 is fixed to the foundation slab concrete by anchor bolts.

[0030] The steel support 3 is a right-angled triangle, including a vertical pole and a horizontal base pole. The pole and the base pole are connected by an inclined brace. An inclined web member is fixedly installed in the middle of the inclined web member. The inclined web member is fixedly connected to the base pole and the pole.

[0031] Several supporting angle steels 6 and steel support plates 7 are installed on the pole body. The two ends of the square steel tube 4 are respectively inserted into the supporting angle steels 6 and steel support plates 7 of two adjacent steel brackets 3.

[0032] The square steel pipe 4 serves as a transverse rigid support rod. After being inserted into the supporting angle steel 6 or angle steel pad 7 of the steel bracket 3, it forms an orthogonal grid system with the longitudinally arranged timber 2. Through this cross layout, the square steel pipe 4 applies a transverse constraint force to the timber 2, limiting the transverse displacement of the timber 2 caused by lateral pressure during concrete pouring, and ensuring the geometric accuracy of the formwork system.

[0033] Timber 2 serves as the longitudinal keel, directly adhering to the outer surface of the formwork, bearing the lateral pressure of the concrete and transferring it to the square steel pipe.

[0034] Two supporting angle steels 6 are fixedly installed at the upper and lower ends of the upright, and the two supporting angle steels 6 are symmetrically arranged on both sides of the upright.

[0035] A steel support plate 7 is fixedly installed in the middle of the upright. The steel support plate 7 is "L" shaped. A slot is provided in the middle of the horizontal part of the steel support plate 7, and the upright of the steel bracket 3 is located in the slot.

[0036] A positioning hole 8 is opened in the middle of the vertical part of the steel support plate 7. The positioning hole 8 passes through the upright and the water-stop screw 5 passes through the positioning hole 8.

[0037] Two mounting plates 9 are respectively provided at both ends of the base rod. The two mounting plates 9 are symmetrically arranged on both sides of the base rod. Each mounting plate 9 has a mounting hole 10 for passing through the anchor bolt.

[0038] When using this utility model, before construction, it is necessary to mark the location of the foundation slab concrete, pre-drill anchor bolt holes, and embed the anchor bolts.

[0039] Place two templates 1 parallel to each other with a spacing consistent with the design thickness of the shear wall, and adjust the verticality of template 1. Then, fix wooden blocks 2 at intervals along the vertical direction on the outside of template 1 as longitudinal joists to enhance the support capacity of template 1. The spacing of the wooden blocks 2 needs to be determined based on the lateral pressure of the concrete to ensure uniform stress.

[0040] Place the steel bracket 3 in the designated position and fix it to the foundation concrete using the mounting plates 9 at both ends of the base rod and the anchor bolts;

[0041] Insert both ends of the square steel pipe 4 into the supporting angle steel 6 or angle steel pad of the adjacent steel bracket 3 respectively, without the need for additional bolts;

[0042] Furthermore, at the corner of template 1, L-shaped square steel pipes 4 can be used to connect the supporting angle steel 6 and the angle steel pad of the adjacent steel support 3 to enhance the overall rigidity and stability of the corner area.

[0043] Through the positioning hole 8 of the vertical part of the angle steel pad, holes are made at the corresponding positions of the steel support 3 upright and the template 1. The water-stop screw 5 is passed through the template 1, the timber 2, the upright, the timber 2 and the template 1 on one side in sequence, and the two ends are tightened with nuts to form a tie fixation.

[0044] The ultra-thick shear wall concrete is poured, and the reaction force provided by the steel support 3 is used to resist the lateral pressure of the concrete. After the concrete reaches the design strength, the components are removed in sequence: first, loosen the nut of the water-stop screw 5 and pull out the screw, then disassemble the square steel pipe 4 and the steel support 3, and finally remove the formwork 1 and the timber 2. The metal components such as the steel support 3 and the square steel pipe 4 can be reused after cleaning. The timber 2 can be recycled or replaced depending on the wear and tear.

[0045] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
