Description

Technical Field

[0001] The present invention relates to the technical field of building construction, and particularly to a high-strength alloy building formwork and its construction process. Background Art

[0002] An alloy building formwork is a formwork system made of aluminum alloy or other metal alloy materials, mainly used for concrete structure construction.

[0003] During the current building construction process, for example, in the pouring of concrete walls, in order to prevent the leakage of mortar at the root of the formwork (the root of the wall) during pouring, ensure that there is no exposed steel bar and no root rot at the wall root after pouring, and at the same time ensure consistent forming effect, usually sand mortar or foam is used to block the root of the formwork before pouring.

[0004] For example, Chinese Patent CN220705182U discloses a new type of aluminum formwork wall bottom caulking device. The scheme includes an aluminum film bottom plate located at the bottom of the aluminum formwork and fixedly connected to the aluminum film formwork, and a caulking plate in contact with the inner surface of the aluminum film bottom plate, including a plurality of fixing mechanisms for fixedly connecting the aluminum film bottom plate and the caulking plate, and a plurality of limiting mechanisms for making the outer side of the caulking plate in close contact with the inner side of the aluminum film bottom plate and quickly positioning the fixing mechanisms. The limiting mechanism makes the aluminum film bottom plate and the caulking plate in close contact to prevent the concrete for building the wall from flowing out of the gap between the aluminum film bottom plate and the caulking plate.

[0005] The above scheme can prevent the concrete from flowing out of the gap between the aluminum film bottom plate and the caulking plate. However, when the length of the aluminum film bottom plate is relatively long, multiple caulking plates need to be connected end to end to adapt to the relatively long aluminum film bottom plate, and the gap between adjacent caulking plates cannot be guaranteed to be sealed, which will cause the concrete to flow out of the gap between adjacent caulking plates, affecting the construction quality. Summary of the Invention

[0006] Based on this, in view of the problem that the concrete is prone to leakage at the aluminum film bottom plate at present, it is necessary to provide a high-strength alloy building formwork and its construction process.

[0007] The above object is achieved by the following technical solutions: A high-strength alloy building formwork, comprising: An alloy formwork, a rubber base is arranged at the bottom of the alloy formwork. The cross-section of the rubber base is C-shaped. The top end of the rubber base is connected to the bottom of the alloy formwork, and the bottom end of the rubber base abuts against the ground; A top push rod, the top push rod is used to push the top end and the bottom end of the rubber base away from each other. Two pressure rods are hinged to the bottom of the top push rod. The two pressure rods are configured to push the two ends of the rubber base to elongate when the top push rod pushes the top end and the bottom end of the rubber base away from each other.

[0008] Further, a connecting sleeve is axially slidably sleeved on the outer periphery of the top push rod. The connecting sleeve is fixedly connected to the top end of the rubber base. A reverse V-shaped rod is provided at the bottom of the top push rod. The two ends of the reverse V-shaped rod are respectively hinged to two pressure rods. Two top blocks are provided at the bottom end of the rubber base. The abutting ends of the two pressure rods are respectively in contact with the two top blocks at the bottom end of the rubber base. Elastic members are provided at the ends of the two pressure rods close to each other. The elastic members can make the abutting ends of the two pressure rods have a tendency to rotate downward around the hinge position.

[0009] Further, an intermediate sleeve is provided between the connecting sleeve and the top push rod. The outer periphery of the intermediate sleeve is axially slidably connected to the inner periphery of the connecting sleeve. The inner periphery of the intermediate sleeve is helically connected to the outer periphery of the top push rod. A slider is axially slidably provided at the bottom of the intermediate sleeve. The slider is slidably connected to the ends of the two pressure rods close to each other. The upper end of the slider is connected to one end of the elastic member, and the other end of the elastic member is connected to the upper part of the intermediate sleeve.

[0010] Further, a locking rod is hinged on the side wall of the connecting sleeve. A coaxial and fixed eccentric disk is provided at the hinged end of the locking rod. The axis of the eccentric disk is perpendicular to the axis of the intermediate sleeve. The outer peripheral wall of the eccentric disk passes through the connecting sleeve and is in frictional contact with the outer periphery of the intermediate sleeve.

[0011] Further, a chute extending along its axis is provided on the intermediate sleeve. A sliding ring is axially slidably provided on the outer periphery of the top push rod. The sliding ring is connected to the elastic member. A limiting rod is fixedly provided on the outer periphery of the sliding ring. The limiting rod is initially located in the chute and at the lower limiting surface of the chute. During the process of the intermediate sleeve moving downward relative to the connecting sleeve, the limiting rod can abut against the upper end of the connecting sleeve to continuously stretch the elastic member.

[0012] Further, connection holes are provided at the bottom of the alloy template and the top end of the rubber base. The connecting sleeve passes through the connection holes. First and second nuts are threadedly connected to the outer periphery of the connecting sleeve. The first and second nuts respectively abut against the upper and lower ends of the two connection through holes.

[0013] Further, a third nut is also threadedly connected to the outer periphery of the connecting sleeve. The third nut is located above the first nut.

[0014] Further, abutting blocks are provided at the ends of the two pressure rods away from each other.

[0015] Further, a rubber block is provided at the bottom end of the rubber base and below the top push rod.

[0016] The present invention also provides a construction process for high-strength alloy building formwork, comprising the following steps: S100. After fixing the position of the alloy formwork, install a plurality of rubber bases; S200. Adjust the distance between the intermediate sleeve and the rubber block according to the size of the gap between adjacent rubber bases, thereby adjusting the elongation distance at both ends of the rubber base; S300. After the adjustment is completed, the operator strikes the upper end of the top push rod so that the intermediate sleeve and the top push rod move downward synchronously to push the rubber base. The abutting ends of the two pressure rods push the two ends of the rubber base to gradually elongate. When the adjacent rubber bases are in close contact, the locking rod locks the position of the intermediate sleeve.

[0017] The beneficial effects of the present invention are as follows: In the present invention, two pressure rods are provided at the bottom of the top push rod. The two pressure rods can push and extrude the two ends of the rubber base to elongate, so that the adjacent rubber bases are tightly connected, avoiding the generation of gaps. Moreover, the abutting ends of the two pressure rods can simultaneously press the bottom end of the rubber base, and together with the pressing at the bottom of the top push rod, a total of three pressing points are formed by one top push rod and two pressure rods. Compared with the traditional multiple guide rods, the installation workload can be reduced, thereby improving the construction efficiency.

[0018] In the present invention, an intermediate sleeve is provided on the outer periphery of the top push rod, and the intermediate sleeve is threadedly connected to the top push rod, so that the top push rod and the intermediate sleeve can move axially relative to each other, thereby adjusting the distance between the bottom end of the center sleeve and the rubber base to adapt to gaps of different sizes.

Detailed implementation manners

[0021] In order to make the objectives, technical solutions and advantages of the present invention clearer and more understandable, the present invention will be further described in detail below through embodiments and in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0022] The serial numbers assigned to the components herein, such as "first", "second", etc., are only used to distinguish the described objects and do not have any sequential or technical meanings. The "connection" and "coupling" mentioned in the present invention, unless otherwise specified, both include direct and indirect connections (couplings). In the description of the present invention, it should be understood that the orientation or positional relationships indicated by the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc. are based on the orientation or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation to the present invention.

[0023] In the present invention, unless otherwise clearly specified and defined, the first feature being "on" or "under" the second feature may mean that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. Moreover, the first feature being "above", "over" and "on top of" the second feature may mean that the first feature is directly above or obliquely above the second feature, or simply indicates that the horizontal height of the first feature is higher than that of the second feature. The first feature being "under", "below" and "beneath" the second feature may mean that the first feature is directly below or obliquely below the second feature, or simply indicates that the horizontal height of the first feature is lower than that of the second feature.

[0024] The following will refer to Figures 1-8 to describe a high-strength alloy building formwork provided by the present invention.

[0025] A high-strength alloy building formwork, which is suitable for the pouring of concrete walls, includes an alloy formwork 100. A rubber base 110 is connected to the bottom of the alloy formwork 100. The cross-section of the rubber base 110 is C-shaped. The top end 120 of the rubber base 110 is connected to the bottom of the alloy formwork 100, while the bottom end 130 of the rubber base 110 abuts against the ground, thereby sealing the gap between the bottom of the alloy formwork 100 and the ground and preventing concrete from leaking out through the gap between the alloy formwork 100 and the ground.

[0026] In the prior art, in order to connect the rubber base 110 to the bottom of the alloy formwork 100, a top push rod 200 is provided at the bottom of the alloy formwork 100. The top push rod 200 can push the upper and lower ends of the C-shaped rubber base 110 away from each other, so that the upper and lower ends of the C-shaped rubber base 110 can be tightly connected to the bottom of the alloy formwork 100 and the ground, preventing concrete from leaking out. However, if the length of the alloy formwork 100 is relatively long, the length of a plurality of rubber bases 110 connected end to end is required to match the bottom of one alloy formwork 100. At this time, gaps may be generated between the plurality of rubber bases 110 during the installation process, which may cause concrete to flow out through the gaps between adjacent rubber bases 110, thereby affecting the construction quality and construction efficiency.

[0027] Therefore, two pressure rods 220 are provided at the bottom of the ejector rod 200 of the present invention. When the two pressure rods 220 move away from each other at the upper and lower ends of the rubber base 110 pushed by the ejector rod 200, the two ends of the rubber base 110 can be pushed to elongate, so that the adjacent rubber bases 110 are squeezed against each other to avoid gaps between the adjacent rubber bases 110. Moreover, the pressure rods 220 can also squeeze the rubber base 110 to be in close contact with the ground, which can reduce the number of ejector rods 200 used. It can be understood that the ejector rod 200 in the prior art can only press one position of the rubber base 110. Three ejector rods 200 are required to press three positions, while the ejector rod 200 and the two pressure rods 220 in the present invention can press three positions of the rubber base 110. Therefore, only one is needed, which can also improve the construction efficiency to a certain extent.

[0028] Specifically, a connecting sleeve 270 is axially slidably arranged on the outer periphery of the ejector rod 200 of the present invention. As shown in Figure 3 , Figure 4 and Figure 5 , the connecting sleeve 270 is fixedly connected to the top end 120 of the rubber base 110, and the connecting sleeve 270 connects the bottom of the alloy template 100 and the top end 120 of the rubber base 110. A reverse V-shaped rod 210 is fixedly connected to the bottom of the ejector rod 200. The two ends of the reverse V-shaped rod 210 are hinged to the two pressure rods 220. The hinged position is close to the ends where the two pressure rods 220 are close to each other. The ends where the two pressure rods 220 move away from each other are abutting ends, and the abutting ends are in contact with the bottom of the rubber base 110. Moreover, two top blocks 140 are arranged at the bottom end 130 of the rubber base 110, and the abutting ends of the two pressure rods 220 are in contact with the two top blocks 140. In the initial state, the included angle between the two pressure rods 220 is an obtuse angle. As the ejector rod 200 is pushed, the included angle between the two pressure rods 220 increases, so that the two top blocks 140 can be pushed to move away from each other. The two top blocks 140 moving away from each other drives the rubber base 110 to slightly elongate, so that the adjacent rubber bases 110 are closely attached to each other without gaps.

[0029] An elastic member 250 is connected to the ends where the two pressure rods 220 are close to each other. The elastic member 250 is initially in a stretched state, so that the abutting ends of the two pressure rods 220 have a tendency to rotate downward with the hinged position as the rotation center. That is to say, when the ejector rod 200 presses the lower end of the rubber base 110, the abutting ends of the two pressure rods 220 can squeeze the bottom end 130 of the rubber base 110 under the action of the elastic member 250. At the same time, the bottom of the ejector rod 200 can also squeeze the bottom end 130 of the rubber base 110, so as to realize that three positions can press the bottom end 130 of the rubber base 110, that is, the number of ejector rods 200 used is reduced, and the construction efficiency is greatly improved.

[0030] More specifically, the lengths by which the two pressing rods 220 in this embodiment push the rubber base 110 to extend are adjustable, and the lengths by which the rubber base 110 extends are positively correlated with the size of the gap between adjacent rubber bases 110. When the gap between adjacent rubber bases 110 is small, the lengths by which the two pressing rods 220 push the rubber base 110 to extend can be reduced; when the gap between adjacent rubber bases 110 is large, the lengths by which the two pressing rods 220 push the rubber base 110 to extend can be increased, so as to ensure that there is no gap between adjacent rubber bases 110.

[0031] The specific structure is as follows: An intermediate sleeve 230 is provided between the connecting sleeve 270 and the top push rod 200. The outer circumference of the intermediate sleeve 230 is axially slidably connected to the inner circumference of the connecting sleeve 270, that is, the intermediate sleeve 230 can axially slide relative to the connecting sleeve 270. The inner circumference of the intermediate sleeve 230 is helically connected to the top push rod 200, that is, threads are provided on the outer circumference of the upper part of the top push rod 200 (not shown in the figure), and then threaded grooves are provided on the inner circumference of the upper end of the intermediate sleeve 230 (not shown in the figure). The threads and the threaded grooves cooperate with each other. Through grooves are provided at positions on the intermediate sleeve 230 corresponding to the two pressing rods 220. The through grooves enable the two ends of the inverted V-shaped rod 210 at the lower end of the top push rod 200 to extend out of the intermediate sleeve 230, facilitating the connection of the two pressing rods 220. A slider 240 is axially slidably provided at the bottom of the intermediate sleeve 230. A sliding groove 241 is provided on the slider 240. One ends of the two pressing rods 220 close to each other are slidably connected in the sliding groove 241 on the slider 240. Specifically, sliding columns are provided at one ends of the two pressing rods 220 close to each other, and the two sliding columns are located in the sliding groove 241. And one end of an elastic member 250 is connected to the upper end of the slider 240. The elastic member 250 is integrally sleeved on the outer circumference of the top push rod 200. The elastic member 250 in this embodiment is a tension spring. The other end of the elastic member 250 is connected to the upper half of the intermediate sleeve 230. At this time, the elastic member 250 is in a stretched state such that the slider 240 abuts against the bottom of the top push rod 200. When the intermediate sleeve 230 rotates relative to the top push rod 200, the intermediate sleeve 230 and the top push rod 200 can move axially relative to each other.

[0032] When the intermediate sleeve 230 moves downward relative to the ejector rod 200, the distance between the bottom of the intermediate sleeve 230 and the rubber base 110 decreases. At this time, the slider 240 still abuts against the lower end of the ejector rod 200 under the action of the elastic member 250. Since the distance between the intermediate sleeve 230 and the base decreases, the ejector rod 200 can abut the intermediate sleeve 230 against the bottom end 130 of the rubber base 110 when it moves downward a short distance. At this time, the distances by which the two pressure rods 220 on the ejector rod 200 push to both sides decrease synchronously, so as to be able to adapt to a smaller gap. When the intermediate sleeve 230 moves upward relative to the ejector rod 200, the distance between the intermediate sleeve 230 and the rubber base 110 increases. At this time, the slider 240 still abuts against the lower end of the ejector rod 200 under the action of the elastic member 250. Since the distance between the bottom of the intermediate sleeve 230 and the rubber base 110 increases, the distances by which the two pressure rods 220 on the ejector rod 200 push to both sides increase synchronously, and thus it can adapt to a larger gap.

[0033] It should be noted that when the ejector rod 200 pushes the two pressure rods 220, since the ends of the two pressure rods 220 that are close to each other are inside the slider 240, the two pressure rods 220 will cause the slider 240 to move downward by disengaging from the contact with the bottom of the ejector rod 200. Therefore, the slider 240 will further stretch the elastic member 250, and the elastic member 250 gives a reaction force to the slider 240. Under the action of the elastic member 250, the slider 240 will cause the abutting ends of the two pressure rods 220 to tightly abut against the bottom end 130 of the rubber base 110, and further, when the pressure rods 220 push and extrude the rubber base 110 to elongate, the bottom end 130 of the rubber base 110 can be tightly abutted against the ground.

[0034] In a further embodiment, as Figure 6 shown, a locking rod 300 is hinged on the side wall of the connecting sleeve 270 of the present invention. A coaxial and fixed eccentric disc 310 is provided at the hinged end of the locking rod 300. The axis of the eccentric disc 310 is perpendicular to the axis of the intermediate sleeve 230. The side wall of the eccentric disc 310 can pass through the side wall of the connecting sleeve 270 and be in frictional contact with the outer periphery of the intermediate sleeve 230. When the ejector rod 200 presses the upper and lower ends of the rubber base 110, the eccentric disc 310 of the locking rod 300 gradually makes close friction with the outer periphery of the intermediate sleeve 230. That is to say, when the eccentric disc 310 rotates, the part with a larger radius gradually presses against the side wall of the intermediate sleeve 230 to gradually clamp the intermediate sleeve 230. After the ejector rod 200 finishes pressing, the locking rod 300 has tightly locked the intermediate sleeve 230 to prevent the intermediate sleeve 230 from resetting. Since the intermediate sleeve 230 is threadedly connected to the ejector rod 200, the ejector rod 200 is also locked.

[0035] Specifically, a clamp 320 is fixedly sleeved on the outer periphery of the connecting sleeve 270. The interface of the clamp 320 is hinged to the rotating shaft of the eccentric disc 310 of the locking rod 300. An opening is provided at a position on the side wall of the connecting sleeve 270 corresponding to the interface of the clamp 320. The side wall of the eccentric disc 310 of the locking rod 300 can be in frictional contact with the side wall of the intermediate sleeve 230 through the opening, so as to lock the intermediate sleeve 230.

[0036] In a further embodiment, to cope with the situation where the gap between adjacent rubber bases 110 is very large, as Figure 6 and Figure 7 shown, a chute 231 extending along its axial direction is provided on the intermediate sleeve 230. A sliding ring 260 is axially slidably arranged on the outer periphery of the ejector rod 200. The sliding ring 260 is specifically located between the outer periphery of the ejector rod 200 and the inner periphery of the intermediate sleeve 230. One end of the elastic member 250 is transferred from the upper part connected to the intermediate sleeve 230 to the sliding ring 260. That is to say, one end of the elastic member 250 is fixedly connected to the sliding ring 260. A limiting rod 261 is fixedly arranged on the outer periphery of the sliding ring 260. The elastic member 250 is initially in a stretched state, so that the limiting rod 261 is initially located at the lower limit surface of the chute 231. When the gap between adjacent rubber bases 110 is relatively large, the intermediate sleeve 230 is adjusted to move upward relative to the ejector rod 200. At this time, the intermediate sleeve 230 and the ejector rod 200 need to move downward a relatively long distance to press against the bottom end 130 of the rubber base 110. And the two pressing rods 220 can also push the rubber base 110 to elongate a relatively long distance. However, at the same time, a relatively large pressure needs to be applied to the rubber base 110 by the two pressing rods 220 to closely attach the bottom end 130 of the rubber base 110 to the ground. Therefore, the acting force of the elastic member 250 on the two pressing rods 220 can be increased, that is, the elastic member 250 is further stretched to increase the acting force on the two pressing rods 220. During the downward movement of the intermediate sleeve 230 and the ejector rod 200, the limiting rod 261 in the chute 231 will contact the upper end of the connecting sleeve 270. At this time, the limiting rod 261 is restricted by the upper end of the connecting sleeve 270, and the sliding ring 260 is also restricted. That is, the elastic member 250 connected to the sliding ring 260 is restricted. When the intermediate sleeve 230 and the ejector rod 200 continue to move downward, the elastic member 250 will be further stretched, so as to increase the acting force of the elastic member 250 on the two pressing rods 220, so that the pressing force of the two pressing rods 220 on the bottom end 130 of the rubber base 110 is greater, so as to ensure that the bottom end 130 of the rubber base 110 can be in close contact with the ground.

[0037] It can be understood that when the gap between two adjacent rubber bases 110 is relatively large, the length that the rubber base 110 needs to extend is relatively long, that is, the deformation degree of the rubber base 110 is greater. When the deformation degree of the rubber base 110 increases, if the top pressure of the pressure rod 220 on the bottom end 130 of the rubber base 110 is not increased, there may be a gap between the rubber base 110 and the ground. Therefore, in the embodiment of the present invention, when dealing with a relatively large gap between adjacent rubber bases 110, the top pressures of two pressure rods 220 on the rubber base 110 are increased simultaneously.

[0038] It should be noted that when the rubber base 110 is installed at the bottom of the alloy template 100, the bottom end 130 of the rubber base 110 has a certain height from the ground. At this time, the middle sleeve 230 and the top push rod 200 need to continue to move downward to push the bottom end 130 of the rubber base 110 into close contact with the ground. At this time, when the rubber base 110 deforms, it will have a reset force. Therefore, the limit rod 261 is restricted at the upper end of the connecting sleeve 270 so that the elastic member 250 is further stretched, thereby increasing the abutting force of the middle sleeve 230 and the top push rod 200 on the bottom end 130 of the rubber base 110 and preventing the bottom end 130 of the rubber base 110 from resetting.

[0039] In a further embodiment, a first nut 271 and a second nut 272 are threadedly connected to the outer periphery of the connecting sleeve 270. The first nut 271 and the second nut 272 are used to fix the connecting sleeve 270 at the top end 120 of the rubber base 110 and fixedly connect the top end 120 of the rubber base 110 and the bottom of the alloy template 100. For the convenience of connection, connection holes are provided at both the top end 120 of the rubber base 110 and the bottom of the alloy template 100. The connecting sleeve 270 passes through the two connection holes at the top end 120 of the rubber base 110 and the bottom of the alloy template 100, and the first nut 271 and the second nut 272 respectively press against the upper end and the lower end of the two connection holes, thereby connecting the alloy template 100 and the rubber base 110.

[0040] Specifically, a third nut 273 is also threadedly connected to the connecting sleeve 270. The third nut 273 is located above the first nut 271. After the first nut 271 and the second nut 272 are tightened, the third nut 273 is rotated so that the third nut 273 presses tightly against the first nut 271, thereby being able to lock the first nut 271 and prevent the first nut 271 from loosening.

[0041] It should be noted that the present invention is not limited to using the first nut 271 and the second nut 272 to connect the alloy template 100 and the rubber base 110, and other structures can also be used to connect the alloy template 100 and the rubber base 110, which are not specifically limited herein.

[0042] In a further embodiment, to increase the contact surface between the abutting ends of the two pressure rods 220 and the rubber base 110, as Figure 6 shown, abutting blocks 221 are provided at the abutting ends of the two pressure rods 220, and the abutting blocks 221 increase the contact area between the abutting ends of the two pressure rods 220 and the rubber base 110.

[0043] In a further embodiment, a rubber block 150 is provided on the bottom end 130 of the rubber base 110 and below the ejector rod 200. The rubber block 150 is used to reduce the top pressing deformation of the ejector rod 200 and the intermediate sleeve 230 on the bottom of the rubber base 110.

[0044] The following describes the specific installation process of a high-strength alloy building formwork provided by the present invention in combination with the above embodiments: First, fix the position of the alloy formwork 100. Subsequently, align the connection holes of the multiple rubber bases 110 with the connection holes of the alloy formwork 100. The connection holes are open-ended. After pushing the connection sleeve 270 into the two connection holes, tighten the first nut 271 and the second nut 272. Then, tighten the third nut 273 to connect the alloy formwork 100 and the rubber base 110. After connecting the multiple rubber bases 110, pull the locking rod 300 to release the restriction on the intermediate sleeve 230, and adjust the distance between the bottom of the intermediate sleeve 230 and the rubber block 150 according to the gap size between adjacent rubber bases 110.

[0045] If the gap between adjacent rubber bases 110 is small, rotate the top push rod 200. The middle sleeve 230 moves axially downward relative to the top push rod 200, thereby appropriately reducing the distance between the middle sleeve 230 and the rubber block 150. The operator uses a hammer to strike the top push rod 200, and the top push rod 200 and the middle sleeve 230 move downward relative to the connecting sleeve 270 synchronously. The locking rod 300 on the connecting sleeve 270 gradually presses the middle sleeve 230 as the connecting sleeve 270 moves downward. The abutting ends of the two pressure rods 220 contact the two top blocks 140 on the rubber base 110 respectively and drive the two top blocks 140 to move away from each other, thereby pushing the two ends of the rubber base 110 to gradually elongate a short distance to adapt to the situation of a small gap. At this time, the ends of the two pressure rods 220 close to each other slide in the sliding groove 241 of the slider 240, driving the slider 240 to move downward to further stretch the elastic member 250. The acting force of the elastic member 250 on the slider 240 enables the abutting ends of the two pressure rods 220 to tightly abut the bottom end 130 of the rubber base 110 against the ground. When the bottom of the middle sleeve 230 abuts on the rubber block 150 and tightly squeezes the rubber block 150, the abutting ends of the two pressure rods 220 simultaneously tightly abut the bottom end 130 of the rubber base 110. At this time, the side wall of the eccentric disk 310 on the locking rod 300 tightly abuts the outer circumference of the middle sleeve 230, so that the positions of the middle sleeve 230 and the top push rod 200 are fixed, and the installation is completed.

[0046] If the gap between adjacent rubber bases 110 is large, it is necessary to rotate the top push rod 200 to make the middle sleeve 230 move upward relative to the top push rod 200, increasing the distance between the middle sleeve 230 and the rubber block 150, so that the middle sleeve 230 can move downward a greater distance. Furthermore, the distance that the abutting ends of the two pressure rods 220 drive the two top blocks 140 to move away from each other increases, and the rubber base 110 elongates a longer distance to adapt to the situation of a large gap. At the same time, when the middle sleeve 230 and the top push rod 200 move downward a longer distance, the limiting rod 261 in the sliding groove 231 of the middle sleeve 230 can abut against the upper end of the middle sleeve 230, so as to further stretch the elastic member 250. The acting force of the elastic member 250 on the slider 240 further increases, so that the acting force of the abutting ends of the two pressure rods 220 on the rubber base 110 increases, thereby ensuring that the bottom end 130 of the rubber base 110 can be tightly attached to the ground to prevent gaps from being generated. When the bottom of the middle sleeve 230 abuts on the rubber block 150 and tightly squeezes the rubber block 150, the abutting ends of the two pressure rods 220 simultaneously tightly abut the bottom end 130 of the rubber base 110. At this time, the side wall of the eccentric disk 310 on the locking rod 300 tightly abuts the outer circumference of the middle sleeve 230, so that the positions of the middle sleeve 230 and the top push rod 200 are fixed, and the installation is completed.

[0047] The present invention also provides a construction process for a high-strength alloy building formwork, which specifically includes the following steps: S100. After fixing the position of the alloy formwork 100, install a plurality of rubber bases 110; S200. Adjust the distance between the intermediate sleeve 230 and the rubber block 150 according to the size of the gap between adjacent rubber bases 110, and then adjust the elongation distance at both ends of the rubber base 110; Among them, the elongation distance at both ends of the rubber base 110 is positively correlated with the gap between adjacent rubber bases 110. When the gap between adjacent rubber bases 110 is small, the elongation distance at both ends of the rubber base 110 is short. When the gap between adjacent rubber bases 110 is large, the elongation distance at both ends of the rubber base 110 is long, so as to adapt to gaps of different sizes.

[0048] S300. After the adjustment is completed, the operator strikes the upper end of the top push rod 200 so that the intermediate sleeve 230 and the top push rod 200 move downward synchronously to push the rubber base 110. The abutting ends of the two pressure rods 220 push the two ends of the rubber base 110 to gradually elongate. When adjacent rubber bases 110 are in close contact, the locking rod 300 locks the position of the intermediate sleeve 230.

[0049] Among them, after the adjustment according to the gap size, the operator uses a hammer to strike the upper end of the top push rod 200 to move the intermediate sleeve 230 and the top push rod 200 downward synchronously, so that the bottom of the intermediate sleeve 230 gradually approaches the rubber block 150. At the same time, the two pressure rods 220 gradually push the rubber base 110 to elongate. When the intermediate sleeve 230 contacts the rubber block 150, adjacent rubber bases 110 are in close contact. At this time, the locking rod 300 fixes the position of the intermediate sleeve 230 to prevent the intermediate sleeve 230 from resetting.
