Abstract

The invention relates to an adjustable support frame for a cup foundation template. The adjustable support frame is formed by connecting an upper back shore, a lower back shore, a central shaft, an angle brace and a wrench through pins. By adjusting the lengths of the upper adjusting lead screw and the lower adjusting lead screw of the upper back shore and the lower back shore, the cup foundation support can adapt to cup foundations of different sizes and can be repeatedly used. The central shaft is rotated to drive the upper turntable and the lower turntable of the upper back shore and the lower back shore to rotate, so that the pins in the eccentric arc-shaped holes of the upper turntable and the lower turntable drive the upper adjusting lead screw and the lower adjusting lead screw to move, and the angle brace compresses and fixes the template; when the rotating disc rotates reversely, the angle brace is pulled to be separated from the formwork, and rapid positioning, rapid supporting and lossless dismantling of the cup opening foundation formwork are achieved. The problems that in the prior art, a cup opening foundation template is difficult to manufacture, install and disassemble, and loss is large when the cup opening foundation template is used once are solved.

Description

Technical Field

[0001] The invention relates to an adjustable supporting frame for a cup opening base template.

[0002] By adjusting the length of the upper and lower adjustment screws of the upper and lower supports, the system can be adapted to the construction of cup-mouth foundation templates of different sizes and reused. The upper and lower turntables of the upper and lower supports are driven by rotating the central axis, and the upper and lower adjustment screws are then driven by pins in the eccentric arc holes of the upper and lower turntables to press the angle braces or pull them apart from the template, achieving rapid positioning, support, and non-destructive removal of the cup-mouth foundation template. This solves the problems of existing cup-mouth foundation templates, such as difficulty in production, installation, and disassembly, and high loss during one-time use. Background Art

[0003] During the construction of the cup-mouth foundation formwork, since the cup-mouth foundation formwork is an inner formwork and has a certain depth, it is difficult to support and fix the formwork, which is time-consuming and labor-intensive. Especially when the formwork is removed after the concrete pouring is completed, if the removal time is too late, the concrete will squeeze and adhere to the formwork, making it impossible to remove the formwork smoothly. The formwork can only be chiseled off, making the formwork only usable once. If the removal time is too early, the cup-mouth foundation concrete may be damaged due to the low strength of the concrete. Summary of the Invention

[0004] The present invention provides an adjustable support frame for a cup-mouth foundation template, which can adapt to cup-mouth foundations of different sizes by adjusting the length of an upper adjusting screw and a lower adjusting screw, and reliably supports the template through the upper adjusting screw, the lower adjusting screw and the angle brace to form a template support system for the cup-mouth foundation; after the concrete is poured and solidified, the plate pin in the rectangular hole of the plate pin hole plate is pulled out, and the central axis is rotated to drive the upper turntable and the lower turntable of the upper top support and the lower top support to rotate, and then the upper adjusting screw and the lower adjusting screw are driven to move by the pins in the eccentric arc holes of the upper turntable and the lower turntable, pulling the angle brace to disengage from the template, first releasing the support and constraint of the adjustable support frame on the template frame, and releasing the pressure of the template block on the template, so that the four inner templates of the cup-mouth foundation continue to lean against the concrete surface independently of each other, and the template can be easily removed after the concrete reaches a certain strength.

[0005] The above technical purpose of the present invention is achieved through the following technical solutions: an adjustable support frame for the cup mouth base template, including: an upper top support (including: an upper adjustment screw, an upper turntable, a tapered plate pin), a lower top support (including: a lower adjustment screw, a lower turntable), a center shaft, an angle support, a wrench, a pin and other connecting parts.

[0006] The central shaft is made of an iron rod, which is composed of a circular shaft body and a square pin shaft welded together into one body. A horizontal circular hole is opened at a certain distance from the upper and lower ends of the shaft body. After the upper and lower supports are sleeved on the central shaft, the pins are inserted into the horizontal circular holes so that the turntables of the upper and lower supports can rotate with the central shaft.

[0007] The angle brace is made of angle iron, and an upper connecting plate is welded between the two wings of the angle iron at a certain distance from the upper end, and a lower connecting plate is welded between the two wings of the angle iron at a certain distance from the lower end; the distance between the lower connecting plate and the lower end of the angle iron is such that when the lower adjusting screw is adjusted to the minimum length and the upper adjusting screw is adjusted to the maximum length, the bottom end of the angle brace is flush with the bottom end of the center axis or the bottom end of the angle brace is slightly lower than the bottom end of the center axis; a template stopper is welded on each side of the upper connecting plate and the lower connecting plate for positioning the template and pressing the template surface; a circular hole is opened in the geometric center of the upper connecting plate, and a pin is passed through the hole, which drives the upper adjusting screw to move when the turntable rotates, pressing the angle brace to fit the end face of the template, and pulling the angle brace away from the template when the turntable rotates in the opposite direction; an elongated hole is opened in the geometric center of the lower connecting plate, and the two ends of the elongated hole are semicircular holes, and the outer corner point of the angle brace when viewed from above is in a straight line with the center line of the long side of the elongated hole and the center of the semicircle; the lower adjusting screw is connected downward When the connecting plate moves in the direction of the elongated hole, the pin in the elongated hole presses the semicircular hole on one side of the elongated hole angle brace of the lower connecting plate to tighten the angle brace; when the lower adjusting screw moves away from the angle brace, the pin in the elongated hole leaves the semicircular hole on one side of the elongated hole angle brace, releasing the pressure of the lower adjusting screw on the lower connecting plate, so that the lower end of the angle brace is in a free state, and the upper end of the angle brace moves toward the center axis under the pull of the upper adjusting screw to disengage from the template. While the lower end of the angle brace is pulled, it has a tendency to act as a fulcrum to rotate the angle brace toward the center axis; when the adjustable support frame and the template jointly form a template box with a cup mouth foundation, the outer surface of the angle iron of the angle brace fits with the end face of the template, and the outer corner of the angle iron coincides with the outer edge of the end face of the template to form the four outer corners of the template box; the inner side of the template is positioned and pressed by the template blocks on the upper and lower connecting plates of the angle brace, and the outer side of the template is fixed by flexible and hard material supports.

[0008] The upper support is composed of an upper turntable, 4 upper adjusting screws, 4 tapered plate pins and connecting pins; the upper turntable is circular and made of iron plate, with a center hole having a diameter slightly larger than the diameter of the center shaft, and the center sleeve is welded on the turntable, the hole of the center sleeve is consistent with the diameter of the center hole of the turntable, and the axes coincide, so that the center shaft passes through it; a horizontal hole is opened on the center sleeve, and after the center shaft passes through, a pin is passed through the horizontal hole so that the center shaft and the upper turntable are locked and can rotate synchronously; 4 eccentric arc holes are evenly arranged on the turntable surface, and semicircular holes are opened at both ends of the eccentric arc hole; in the horizontal projection plane, the center lines of the two semicircular holes at both ends of the eccentric arc hole have different distances from the center line of the center shaft, one is a long-distance semicircular hole, and the other is a close-distance semicircular hole. When the turntable rotates, the pin in the eccentric arc hole can move toward or away from the direction of the angle support; 4 plate pin hole plates are welded on the circumferential side of the turntable, and rectangular holes are opened on the plates to plug the tapered plate pins.

[0009] The upper adjustment screw of the upper turntable is composed of an inner screw and an outer screw, and the inner screw is rotated on the outer screw; one end of the inner screw facing the turntable and the other end of the outer screw facing the angle brace are respectively welded with perforated plates, and pins are inserted into the holes to connect with the turntable and the angle brace connecting plate respectively; according to the designed cup-mouth base upper edge size, the length of the upper adjustment screw is determined at this time, and the inner screw and the outer screw are rotated so that the rectangle formed by the upper ends of the outer corners of the four angle braces is the same as the designed cup-mouth base upper edge size; in the horizontal projection plane, the center of the central axis, the center of the long-distance semicircular hole of the eccentric arc hole of the upper turntable, and the upper end of the angle brace are all aligned. When the center of the connecting plate hole and the outer corner of the angle brace are in a straight line, the upper adjusting screw is in a state of pressing the angle brace tightly. In this state, the angle iron surface of the angle brace fits against the end face of the template, the template block presses the template, and a tapered plate pin is placed in the plate pin hole plate to limit the rotation of the turntable, so that the adjustable support frame and the template form a stable template system; when the tapered plate pin in the plate pin hole plate is pulled out and the upper turntable is rotated in the opposite direction, the upper adjusting screw is driven by the pin in the eccentric arc hole, and the upper adjusting screw pulls the upper connecting plate of the angle brace toward the center, so that the angle iron surface of the angle brace is disengaged from the end face of the template.

[0010] The lower support consists of a lower turntable, 4 lower adjusting screws, and connecting pins; the lower turntable is circular, made of iron plate, and has a center hole. The center sleeve is welded to the turntable. The hole of the center sleeve has the same diameter as the center hole of the turntable, and the axis coincides, so that the center shaft passes through it; a horizontal hole is opened on the center sleeve, and after the center shaft passes through, a pin is passed through the horizontal hole, so that the center shaft drives the lower turntable to rotate; 4 eccentric arc holes are opened on the turntable surface, which are the same as those of the upper turntable.

[0011] The lower adjusting screw of the lower top support is composed of an inner screw and an outer screw, the inner screw is rotated on the outer screw, and the inner screw is welded to one end of the turntable and the outer screw is welded to one end of the angle support with a hole plate, and pins are inserted into the holes at both ends, respectively connected to the turntable and the angle support connecting plate; according to the designed cup base bottom size, the length of the lower adjusting screw is adjusted in the same way as rotating the upper adjusting screw; the rectangle formed by the lower ends of the outer corners of the four angle supports is the same as the designed cup base bottom size; in the horizontal projection plane, the center of the central axis, the center of the long-distance semicircular hole of the eccentric arc hole of the lower turntable, the lower connecting plate of the angle support When the center line of the long hole of the connecting plate and the outer angle of the angle brace are in a straight line, the lower adjusting screw is in a state of pressing the angle brace tightly. In this state, the pin of the lower adjusting screw in the outer screw plate hole presses the outer edge of the long hole of the lower connecting plate and the lower connecting plate, so that the angle iron surface of the angle brace fits with the end face of the template, and the template block presses the template surface, so that the adjustable support frame and the template form a stable template system; when the lower turntable rotates in the opposite direction, the pin in the eccentric arc hole drives the lower adjusting screw to move toward the center axis, and the pin in the outer screw hole plate of the lower adjusting screw is loosened from the outer edge of the long hole of the lower connecting plate, so that the lower end of the angle brace is in a free state.

[0012] The wrench is composed of a wrench handle and a square pin hole head welded together. After the square pin hole head is mounted on the square pin shaft of the center shaft, twisting the wrench can rotate the center shaft. When the wrench drives the center shaft to rotate, the turntables of the upper and lower supports rotate with the center shaft, thereby driving one end of the upper adjustment screw to move within the eccentric arc hole on the upper turntable through the pin, so that the upper adjustment screw is moved toward or away from the angle brace, and the other end of the upper adjustment screw is pressed against the angle brace through the pin, so that the angle brace surface fits with the template end face, and the template block of the upper connecting plate presses the template face. Alternatively, the wrench can be rotated in the opposite direction, and the pin pulls the angle brace to separate the angle brace surface from the template end face, and the template block of the upper connecting plate releases the template face.

[0013] The entire device is made of steel and assembled, and can be used repeatedly.

[0014] Furthermore, the template can be made of steel plates or cut using wooden templates.

[0015] Furthermore, according to the designed cup mouth base size, the threads of the upper adjustment screw and the lower adjustment screw of the adjustable support frame are rotated to adjust the outer frame size of the cup mouth base formed by the four corner braces, and the size of the single-piece template is made according to the gap size between adjacent corner braces.

[0016] Furthermore, the length of the template stopper on the angle brace connecting plate extending toward the template surface can be adjusted according to force calculation.

[0017] Furthermore, the joint surface between the end face of each formwork and the angle brace can be padded with sealing material to prevent leakage of concrete during pouring.

[0018] Furthermore, lubricant can be applied to the contact and rotating parts of the center shaft and the upper and lower turntables to reduce friction during rotation; lubricant can be applied to the contact parts of the upper and lower adjustment screw pins and the eccentric arc holes and the angle support connecting plate holes to reduce friction when the adjustment screw moves.

[0019] Furthermore, whether the middle connecting plate in the middle section of the angle brace and the template stopper on the middle connecting plate are provided is determined by force calculation according to the specific size of the cup mouth foundation.

[0020] Furthermore, when setting the middle connecting plate, the form of the middle connecting plate is the same as that of the lower connecting plate, and a long hole is opened on the connecting plate, so that when the upper screw pulls the upper end of the angle brace to move toward the center axis, the angle brace tends to rotate toward the center axis with its lower end as the fulcrum, and the angle iron surface of the angle brace separates from the end face of the template.

[0021] Furthermore, in order to prevent the pin from falling off during operation, after the pin is inserted into the corresponding position, a cotter pin is inserted at both ends of the pin, or a pier head larger than the diameter of the pin is set at one end and a cotter pin is inserted at the other end.

[0022] Beneficial effects of the present invention: The invention provides an adjustable support frame for a cup-mouth foundation template. The structure is reliable, the load-bearing capacity is strong, and the installation and disassembly are tool-based and quick. The adjustable support frame can adapt to the construction of cup-mouth foundations of different sizes by adjusting the length of the screw. First, the length of the upper and lower adjustment screws is adjusted according to the size of the designed cup-mouth foundation. After assembly, an overall assembly structure with the same size as the designed cup-mouth foundation is formed. After the adjustable support frame is installed in place, it forms a template support system together with the template. After the concrete solidifies, the screw is driven to move by rotating the central axis and the turntable, and the constraint of the adjustable support frame on the template is first released, avoiding the damage to the concrete caused by premature removal of the template inside the foundation. After the concrete reaches a certain strength, the templates that are no longer constrained to each other are removed, avoiding the problem of difficulty in removal caused by too late removal, without damaging the template, and the template can be reused.

[0023] The device complies with the national green construction requirements and has good technical and economic benefits and promotion and application value. BRIEF DESCRIPTION OF THE DRAWINGS
