Description

Technical Field

[0001] This utility model relates to the field of building construction technology, specifically to a temporary support lattice column that can be efficiently dismantled. Background Technology

[0002] In the construction of cast-in-place concrete structures, temporary support lattice columns are key components for load transfer during the construction period, and their removal faces the following technical bottlenecks:

[0003] 1. The demolition of a single lattice column requires steps such as cutting, hoisting, and repair, which is time-consuming and slow in construction progress;

[0004] 2. After cutting, the lattice columns need to be transported out of the construction area by crane or forklift, which may be subject to site restrictions, making transportation difficult and delaying the construction progress.

[0005] 3. The high temperature generated by oxyacetylene cutting leaves burn marks on the concrete surface, which has a significant impact on the aesthetics;

[0006] 4. Components such as lattice column slabs and angle steel can cause spatial interference to the arrangement of steel bars on the slab surface, blocking the straight path of the steel bars and causing the steel bars to be forced to bend or be raised.

[0007] 5. If the cast-in-place slab in the lattice column area is to be removed and rebuilt, it is necessary to re-install the reinforcing bars or reserve interfaces, which makes the construction process complicated.

[0008] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Utility Model Content

[0009] To overcome the shortcomings of existing technologies, a temporary support lattice column that can be efficiently dismantled is provided to solve the problem of slow construction progress in the dismantling of existing temporary support lattice columns.

[0010] To achieve the above objectives, a temporary support lattice column that can be efficiently dismantled is provided, comprising:

[0011] Lattice column body;

[0012] The column frame includes a support and a clamping plate. The support is attached to the outer side of the lacing plate on one side of the lattice column body, and the clamping plate is attached to the inner side of the lacing plate. A tie is connected between the support and the clamping plate.

[0013] A support plate, which is supported on the bottom formwork of the floor slab, is laid on the support. A sealing plate is vertically installed on the side of the support plate near the lattice column body. The top of the sealing plate is higher than the upper surface of the floor slab. The sealing plates around the lattice column body form a retaining cylinder that is fitted onto the outside of the lattice column body.

[0014] Furthermore, the support includes:

[0015] A substrate is attached to the outer side of the splice plate, and the substrate is connected to the clamp plate by the tie member;

[0016] A top plate, connected to the top of the substrate and supported by the bottom template;

[0017] A support plate is provided on the side of the top plate and the base plate that is away from the lattice column body.

[0018] Furthermore, the support plate is disposed in the middle of the top plate.

[0019] Furthermore, there are multiple tie members, and multiple tie members are respectively provided on the upper and lower sides of the gusset plate.

[0020] Furthermore, the tie member includes:

[0021] The pull screw has a first through hole on the base plate and a second through hole on the clamping plate, and the pull screw is movably inserted through the first through hole and the second through hole;

[0022] The two ends of the pull screw are respectively screwed with screw components, one screw component pressing against the outer side of the base plate, and the other screw component pressing against the outer side of the clamping plate.

[0023] The beneficial effects of this utility model are as follows: the lattice column body of this utility model, which can be efficiently dismantled, penetrates through the floor slab. Because the surrounding retaining plates of the lattice column body form a retaining cylinder that surrounds the column body, concrete poured on the bottom formwork of the floor slab will not enter the lattice column body. After the concrete hardens, a hole is formed in the floor slab at the lattice column body. When the column support is dismantled, the entire lattice column body can be vertically pulled out, shortening the construction period by 30-40% compared to traditional cutting methods. It also avoids damage to the concrete appearance, micro-cracks, and steel reinforcement caused by high-temperature cutting, avoiding secondary structural repairs, saving repair materials and labor costs, and shortening the construction period. After the column is pulled out, the pre-bent-upward-curved floor slab reinforcement can be repositioned using the hole left when the lattice column is pulled out, allowing for direct pouring of concrete.

[0027] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the relevant utility model and not intended to limit the scope of the utility model. Furthermore, it should be noted that, for ease of description, only the parts relevant to the utility model are shown in the accompanying drawings.

[0028] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0029] Reference Figure 1 and Figure 2 As shown, this utility model provides a temporary support lattice column that can be efficiently dismantled, including: lattice column body 1, column attachment frame 2, and support plate 3.

[0030] The lattice column body 1 includes limbs and gusset plates.

[0031] The column support 2 includes a support 21 and a clamping plate 22. The support 21 is attached to the outer side of the lacing plate 11 on one side of the lattice column body 1. The clamping plate 22 is attached to the inner side of the lacing plate 11. A tie rod 23 connects the support 21 and the clamping plate 22.

[0032] A support plate 3 is provided on the bottom formwork 5 of the floor slab 4. It is laid on the support 21. A sealing plate 31 is erected on the side of the support plate 3 near the lattice column body 1. The top of the sealing plate 31 is higher than the upper surface of the floor slab 4. The sealing plates 31 around the lattice column body 1 form a retaining cylinder that is fitted onto the outside of the lattice column body 1.

[0033] This utility model discloses a highly efficient removable temporary support lattice column. The lattice column body penetrates the floor slab. Because the surrounding retaining plates form a retaining cylinder that surrounds the lattice column body, concrete poured onto the bottom formwork of the floor slab will not enter the lattice column body. After the concrete hardens, a hole is formed in the floor slab at the lattice column body. When the column support frame is dismantled, the entire lattice column body can be vertically pulled out, shortening the construction period by 30-40% compared to traditional cutting methods. It also avoids damage to the concrete appearance, micro-cracks, and steel reinforcement caused by high-temperature cutting, eliminating the need for secondary structural repairs, saving repair materials and labor costs, and shortening the construction period. After the column is pulled out, the pre-bent-upward-curved floor slab reinforcement can be repositioned using the hole left during the lattice column removal, allowing for direct concrete pouring.

[0034] In a preferred embodiment, the support 21 includes a base plate 211, a top plate 212, and a support plate 213.

[0035] The substrate 211 is attached to the outer side of the gusset plate 11. The substrate 211 is connected to the clamp plate 22 by the tie rod 23. The top plate 212 is connected to the top of the substrate 211 and supported by the bottom template 5. The support plate 213 is supported on the side of the top plate 212 and the substrate 211 away from the lattice column body 1.

[0036] In this embodiment, the support plate 213 is disposed in the middle of the top plate 212.

[0037] In a preferred embodiment, there are multiple tie members 23. Multiple tie members 23 are respectively provided on the upper and lower sides of the gusset plate 11.

[0038] Specifically, the tie rod 23 includes a tie rod and a threaded connection.

[0039] The substrate 211 has a first through hole. The clamping plate 22 has a second through hole. The pull screw is movably inserted through the first and second through holes. Each end of the pull screw is screwed with a threaded engagement member. One threaded engagement member presses against the outer side of the substrate 211. The other threaded engagement member presses against the outer side of the clamping plate 22.

[0040] In this embodiment, the screw is a nut.

[0041] When pouring concrete floor slabs, the steel bars 41 on the slab surface bend upwards and stick tightly to the sealing plate when they encounter the sealing plate. This can prevent the cast-in-place concrete from flowing into the column body of the lattice column, so that the cast-in-place concrete will not invade the lattice column area and form a square hole slightly larger than the projected area of ​​the lattice column.

[0042] Before pouring the concrete floor slab, when the 41-path of the slab reinforcement is blocked by the sealing plate, it bends upward at 90 degrees close to the sealing plate, and the length of the bent part is L (L must meet the requirements of the reinforcement lap splice specification).

[0043] After the concrete slab is poured and reaches the required structural strength, the lattice column can be vertically lifted and dismantled as a whole. The specific method is as follows: a vertical extraction device (a hydraulic jacking system with a lifting force of 2-3 times the column's own weight, used in conjunction with a truck crane) is used to directly pull out the lattice column body vertically. This method solves the technical problems of structural damage, low construction efficiency, and difficult transportation caused by the need for later cutting and chiseling due to the lattice column being encased in concrete, which are common in traditional processes.

[0044] After the temporary supporting lattice columns are vertically lifted and removed as a whole, and the concrete slab has reached the strength required for demolding, the bottom formwork can be removed. After removing the bottom formwork, the 90-degree bent slab reinforcement bars should be restored to a horizontal position.

[0045] After restoring the 90-degree bent slab reinforcement to a horizontal position, the opposite slab reinforcements on the same path should be lapped together, and the lap length must meet the requirements of the drawings and specifications. Install the formwork for the secondary concrete pouring and pour concrete to fill the opening. This method eliminates the need for re-installing reinforcement, making construction convenient and quick, and avoiding the possibility of damage to the original concrete slab during the process.

[0046] The above description is merely a preferred embodiment of this application and an explanation of the technical principles employed. Those skilled in the art should understand that the scope of the utility model involved in this application is not limited to the technical solutions formed by specific combinations of the above-described technical features, but should also cover other technical solutions formed by arbitrary combinations of the above-described technical features or their equivalents without departing from the inventive concept. For example, technical solutions formed by substituting the above features with (but not limited to) technical features with similar functions disclosed in this application.
