Technical Field
[0001] This application relates to the technical field of construction formwork, and particularly relates to a floor support system and method for early removal formwork in buildings. Background Art
[0002] Currently, most building structures are concrete construction structures. Their construction requires building formwork, then laying steel bars and pouring concrete. Among various formwork technologies, there is a so-called early removal formwork technology, which uses early removal heads, steel structure supports, beams, etc. to form a support structure to support the floor slab and the corresponding formwork of the floor slab.
[0003] The above support system has the following deficiencies currently: A cross beam is erected on two early removal heads, and the formwork is above the early removal heads. This results in the need to first remove the cross beam and then the formwork. Since the cross beam supports the formwork, in order to facilitate the removal of the cross beam, an operable space needs to be left between the cross beam and the formwork. Usually, the early removal head is threadedly connected to the vertical pole, so that by rotating the early removal head, it can be temporarily lowered a small distance, and then one end of the cross beam is manually removed from the early removal head it supports first. However, because the other end of the cross beam is still on another early removal head, a rod with a fork needs to be used to temporarily support the first removed end, and then the other end is removed from the early removal head.
[0004] In the above process, it is easy for the cross beam to accidentally slip, posing a safety hazard and damaging the cross beam; and if two workers are required to remove it from both ends together, the labor occupation is relatively large. Therefore, this application proposes a new technical solution. Summary of the Invention

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0018] The following further Figure 1-2 describes the present application in detail with reference to the attached
[0019] An embodiment of the present application discloses a floor support system for early removal formwork in construction.
[0020] Referring to Figure 1 , the floor support system for early removal formwork in construction includes a main strut 1 and a bracket 11. The bracket 11 is sleeved on the main strut 1. The cross beam includes a main beam and a secondary beam. The main beam and the secondary beam are arranged crosswise, and the main beam is placed on the bracket 11, and the secondary beam is placed on the main beam. Then, the bottom formwork is laid on the secondary beam to complete formwork support.
[0021] In order to facilitate the downward movement of the cross beam when disassembling the cross beam, the present system includes a positioning mechanism 2 for positioning the bracket 11 and a descending mechanism 3 for descending the bracket 11. The descending mechanism 3 includes a water storage pipe 31, a valve and a controller.
[0022] Among them, multiple water storage pipes 31 are provided and nested with each other to form a telescopic structure. In this embodiment, taking three water storage pipes 31 as an example, the three water storage pipes 31 are all sleeved outside the main support rod 1. The upper end of the outermost water storage pipe 31 (the uppermost section in the extended state) is connected to the bracket 11. Both the upper and lower ends of the water storage pipe 31 are sealed. A water storage cavity is formed between the inner wall of the water storage pipe 31 and the outer wall of the main support rod 1 (in this embodiment, only the first and second water storage pipes 31 are provided with water storage cavities, and the third water storage pipe 31 only plays a telescopic role). The top end of the second water storage pipe 31 is located in the water storage cavity of the first water storage pipe 31, and the top end of the third water storage pipe 31 is located in the water storage cavity of the second water storage pipe 31, thus forming a nested telescopic structure; the top end of the second water storage pipe 31 is in sealed contact with the inner wall of the water storage cavity of the first water storage pipe 31 by setting a sealing piston, and the third water storage pipe 31 is the same.
[0023] The uppermost water storage pipe 31 is provided with a water inlet interface for water injection. Water channels for communicating adjacent water storage cavities are opened at the tops of the water storage pipes 31 moved into other sections. Thus, the water injected into the uppermost water storage pipe 31 can be injected into the second water storage pipe 31 through the water channels. (In this embodiment, the second water storage pipe 31 is provided with a water outlet interface. In other embodiments, if the innermost water storage pipe 31 is provided with a water storage cavity, a water outlet interface for water outlet is provided in the innermost water storage pipe 31). The lower end face of the innermost water storage pipe 31 (the lowermost section in the extended state) abuts against the convex platform preset on the main support rod 1.
[0024] In this embodiment, the valves are electric control valves, which are respectively arranged at the water inlet interface and the water outlet interface. The controller is electrically connected to the valves and configured as: When receiving a water injection instruction initiated by the user, it controls the valve at the water outlet interface to close and the valve at the water inlet interface to inject water until the preset water injection in-place condition is met; If receiving a lowering instruction initiated by the user, it controls the valve at the water outlet interface to discharge water.
[0025] It can be understood that the water injection instruction can be that the user presses a button preset on the control cabinet at the construction site; the water injection in-place condition can be the water injection volume when all the water storage pipes 31 are filled; the lowering instruction can be that after the user cancels the positioning of the bracket 11 by the positioning mechanism 2, presses a button preset on the control cabinet at the construction site; the water inlet interface and the water outlet interface are respectively connected to water pipes, and the water pipes are connected to a water tank. The water in the water tank is pumped into the water pipe connected to the water inlet interface through a water pump to realize water injection into the water storage pipe 31; if it is necessary to number the valves on each main support rod 1 for early removal, when the cross beam needs to be removed, the opening and closing of each valve can be controlled according to the numbers of each valve.
[0026] With the above settings, when it is necessary to remove the crossbeam, first control the valve at the water outlet interface to close, and then control the valve at the water inlet interface to inject water until the water storage pipe 31 is filled with water. Then, disassemble the positioning mechanism 2, so that the bracket 11 presses down on the water storage pipe 31 due to the gravity of the crossbeam. After that, drain the water, so that the bracket 11 drives the uppermost water storage pipe 31 to move downward, causing each water storage pipe 31 to contract in sequence, thereby enabling the bracket 11 to drive the crossbeam to descend to a low position, which is convenient for personnel to remove the crossbeam from the bracket 11, reducing potential safety hazards and manpower occupation.
[0027] In another embodiment of the present application, considering that the water flow rate will be affected by the decrease in the water level in the water storage cavity during the descent of the water storage pipe 31, causing the descent speed of the bracket 11 to gradually decrease. In order to be able to adjust the water flow rate in real time, enable the bracket 11 to maintain a constant descent, and improve efficiency, the following settings are made: A gravity sensor is installed on the contact surface between the bracket 11 and the crossbeam, and the gravity sensor is electrically connected to the controller. The controller is configured as follows: 1). Obtain the gravity data fed back by the gravity sensor; 2). Based on the gravity data, search the preset database to determine the matching target water outlet speed; It can be understood that in order to enable the bracket 11 to descend safely and smoothly, for crossbeams of different weights placed on the bracket 11, it is necessary to set the target water outlet speed. Therefore, a relationship table of target water outlet speeds corresponding to multiple groups of gravity data is pre-stored in the database. The specific gravity data and the corresponding target water outlet speeds can be obtained through experiments.
[0028] 3). Based on the target water outlet speed, generate an opening control command for controlling the valve opening parameter of the water outlet interface; It can be understood that according to the operation manual of the valve set at the water outlet interface, the valve opening parameters corresponding to each water outlet speed are pre-stored in the database in advance. By searching the database, the matching valve opening parameters are determined, and the valve is controlled to execute based on the valve opening parameters.
[0029] 4). Based on the distance data fed back by the distance sensor, calculate the actual descent speed of the bracket 11; It can be understood that during the descent of the bracket 11, the distance data is detected in real time. For example, the position data of the bracket 11 is obtained through the distance data, and the actual descent speed is obtained by differentiating the position data.
[0030] 5). Based on the analysis of the actual descent speed of the bracket 11 and the target water outlet speed, adjust the valve opening parameter of the water outlet interface.
[0031] For example, if the actual descent speed of the bracket 11 is less than the target water outlet speed, increase the valve opening (such as 5%) to increase the water outlet speed.
[0032] With the above settings, by dynamically adjusting the water outlet speed of the water outlet interface, the bracket 11 can descend steadily, thereby improving the overall disassembly efficiency.
[0033] In another embodiment of the present application, in order to be able to observe in time whether the water storage pipe 31 leaks and replenish water to the water storage pipe 31 in time, the bracket 11 presses down on the water storage pipe 31 to make the water storage pipe 31 descend more smoothly and stably. Therefore, a colored liquid (colored pigment is dropped into the water) is injected into the water storage pipe 31. The water storage pipe 31 is detachably connected to the bracket 11. A ranging sensor is installed at the top of the water storage pipe 31, and the detection end of the ranging sensor faces upward. It should be noted that the distance data measured by the ranging sensor is the distance between the top of the water storage pipe 31 and the bottom mold, and the bracket 11 does not block the detection path of the detection end of the ranging sensor.
[0034] Wherein, the controller is electrically connected to the ranging sensor and is configured to: Obtain the distance data fed back by the ranging sensor; If the distance data exceeds the preset standard threshold (example: the standard threshold can be the distance value between the bracket 11 and the bottom mold), then compare the distance data with the standard threshold to obtain a difference value, and calculate the water replenishment amount according to the difference value and the pre-stored cross-sectional area of each water storage cavity; Exemplary: The water storage pipe 31 is composed of three nested pipes, and the example parameters are as follows: The outer layer (the first section): the cross-sectional area is 0.05 m², and the maximum contraction length is 0.2m; The middle layer (the second section): the cross-sectional area is 0.04 m², and the maximum contraction length is 0.25m; The inner layer (the third section): the cross-sectional area is 0.03 m², and the maximum contraction length is 0.3m; If the difference value is 0.25m, that is, the contraction value is 0.25m; Regarding the calculation of the water replenishment amount: The first section is shortened by 0.2m, and the water replenishment amount is 0.05 * 0.2 = 0.01m³ The second section is shortened by 0.25 - 0.2 = 0.05m, and the water replenishment amount is 0.04 * 0.05 = 0.002m³ The total water replenishment amount: 0.01m³ + 0.002m³ = 0.012 m³.
[0035] It should be noted that the above parameters are for example to clearly describe the calculation of the water replenishment amount. If the actual leakage results in a large distance contraction value (exceeding the maximum contraction length of the first section of the water storage pipe 31) as in the above example, the water storage pipe 31 should be replaced.
[0036] Generate a water replenishment control instruction for controlling the opening of the valve and the pre-connected pump based on the water replenishment amount.
[0037] With the above settings, if colored liquid is found to flow out, the water storage pipe 31 is disassembled and separated from the bracket 11. The water storage pipe 31 drops due to gravity. By measuring the downward displacement distance of the water storage pipe 31, the water replenishment amount is calculated, and the water storage pipe 31 is replenished with water in time, so that the bracket 11 can descend safely and stably.
[0038] In another embodiment of the present application, in order to prevent the situation where the staff raises the cross beam before the bracket has descended in place, or there is an obstacle hindering the downward movement of the cross beam during the descent of the cross beam, the controller is further configured as follows: Each gravity sensor and the valve at the water outlet pipe interface are numbered respectively, and the gravity sensors on two adjacent main support rods 1 and the valve at the water outlet pipe interface are defined as a group, and a group number is set; Example: The numbers of each gravity sensor are af1, af1, bf1, bf2, cf1, cf2..., the numbers of the valves at the water outlet pipe interfaces are al1, al2, bl1, bl2, cl1, cl2..., and two adjacent main support rods 1 are a group (supporting the same cross beam together), and the group numbers are A, B, C.... Then the numbers of the gravity sensors in group A are af1 and af2, and the numbers of the valves are al1 and al2.
[0039] If any gravity sensor does not detect gravity data, the number of this gravity sensor is called, and it is determined whether the other gravity sensor in the same group has detected gravity data. If so, the group number is called, and the valve at the water outlet pipe interface on the main support rod 1 in the same group is controlled to stop discharging water.
[0040] It can be understood that if the gravity sensor numbered af2 does not detect gravity data, and af1 in the same group has detected gravity data, it means that one end of the cross beam has left the bracket, then the valves numbered al1 and al2 in the same group are controlled to stop discharging water, so that the two brackets stop descending.
[0041] In another embodiment of the present application, in order to more conveniently control the synchronous descent of the two brackets supporting the same cross beam, the system further includes a connecting pipe. The two ends of the connecting pipe are respectively connected to the water outlet pipe interfaces on two adjacent main support rods 1, and the two adjacent main support rods support the same cross beam. The connecting pipe is provided with a water discharge pipe, and a valve is arranged at the water discharge pipe, so that the two brackets on the two adjacent main support rods can be synchronously descended by controlling one valve.
[0042] In another embodiment of the present application, the positioning mechanism 2 includes a positioning rod 21 slidably penetrating through the bracket 11. The main support rod 1 is provided with a support pin hole 22 for the positioning rod 21 to penetrate horizontally. The positioning rod 21 penetrates through the bracket 11 and the support pin hole 22, thereby providing a supporting force for the bracket 11.
[0043] Since in case of water leakage, the water replenishment amount needs to be measured to replenish the water storage pipe 31, the water storage pipe 31 needs to be disassembled and separated from the bracket 11. Therefore, the positioning rod 21 includes a long rod 211, a short rod 212 and a bent rod 213. The bent rod 213 is bent and one end thereof is fixed to one end of the short rod 212, and the other end is fixed to one end of the long rod 211, and the long rod 211 is parallel to the short rod 212. Thus, the long rod 211, the bent rod 213 and the short rod 212 together form a U-shaped structure. A first connecting piece 3 is welded to the bracket 11, and a second connecting piece 4 is welded to the upper end of the water storage pipe 31. The first connecting piece 3 and the second connecting piece 4 are attached to each other and a connecting hole 5 is communicatedly provided. The short rod 212 passes through the connecting hole 5, and the long rod 211 passes through the bracket 11 and the support pin hole 22. The length of the long rod 211 is greater than the sum of the length of the short rod 212 and the width of the bracket 11.
[0044] Through the above settings, in the formwork support state, the long rod 211 and the short rod 212 respectively pass through the support pin hole 22 and the connecting hole 5, which not only plays a role in fixing the bracket 11, but also synchronously positions the water storage pipe 31 and the bracket 11, facilitating subsequent water injection.
[0045] Among them, the disassembly of the positioning rod 21 is described as follows: The first case: If water leakage is found, the staff can use a hammer to strike the long rod 211 to move it as a whole, so that the short rod 212 is removed from the connecting hole 5, and then the water storage pipe 31 and the bracket 11 are separated. Since the length of the long rod 211 is greater than the sum of the length of the short rod 212 and the width of the bracket 11, the long rod 211 still passes through the support pin hole 22. Due to water leakage, the water level in the water storage cavity of the water storage pipe 31 drops, leaving a space in the upper part. Then the water storage pipe 31 will move downward due to gravity. After that, according to the above content, the water replenishment amount can be measured to replenish the water storage pipe 31, so that the water storage pipe 31 moves upward and returns to the fixed position together with the bracket 11 again; After that, continue to move the long rod 211 and pull out the long rod 211 from the support pin hole 22, so as to separate the bracket 11 from the main support rod 1. The bracket 11 drives the cross beam to press down the water storage pipe 31, and the water outlet interface discharges water, then the water storage pipe 31 drives the bracket 11 to move downward.
[0046] The second case: If no water leakage is found, directly pull out the long rod 211 from the support pin hole 22, then the short rod 212 will also be removed from the connecting hole 5. The bracket 11 drives the cross beam to press down the water storage pipe 31, and the water outlet interface discharges water, then the water storage pipe 31 drives the bracket 11 to move downward.
[0047] The embodiment of the present application also discloses a floor support method for an early demolition formwork for buildings.
[0048] A floor support method for applying the floor support system for an early demolition formwork for buildings as described in any one of the above, includes the following steps: S1. Formwork erection: Set up the main strut 1, position the bracket 11 through the positioning mechanism 2, drive the water storage pipe 31 to extend by the hook of the bracket 11, place the cross beam, and lay the formwork; S2. Preparation before formwork removal: Inject colored liquid into the water storage pipe 31, observe whether there is water leakage in the water storage pipe 31. If there is water leakage, disassemble and separate the bracket 11 from the water storage pipe 31, automatically calculate the required water replenishment amount according to the distance of the real-time detection of the water storage pipe 31 dropping, and replenish water to the water storage pipe 31; S3. Lower the bracket 11: Release the positioning effect of the positioning mechanism 2 on the bracket 11, and drain water through the water outlet pipe interface. Real-time detect the descending speed of the bracket 11, and automatically adjust the water outlet speed of the water outlet pipe interface; S4. Demount the cross beam and formwork.
[0049] The above are all the preferred embodiments of the present application, and the protection scope of the present application is not limited by this. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
