Description

Technical Field

[0001] This utility model relates to the field of slope concrete pouring, and in particular to an auxiliary construction device for slope concrete pouring. Background Technology

[0002] The existing method for pouring concrete on slopes involves installing and pouring steel formwork section by section from the bottom of the slope upwards. This process requires the use of full-span scaffolding or large lifting platforms as support for the installation of the steel formwork. The ends of the steel formwork are connected to reinforcing bars perpendicular to the slope. After the steel formwork is installed, concrete can be poured. Once the concrete has solidified, the connection between the reinforcing bars and the steel formwork is severed, and the steel formwork is then dismantled. The existing method of steel formwork installation requires scaffolding, which is inefficient; using large lifting platforms significantly increases costs.

[0003] The patent application number "201821145466.0" entitled "A Concrete Pouring Formwork for High Slopes and Large Spans" utilizes a lower support and upper support walking unit to achieve the support and movement of the concrete pouring formwork. Although this mobile slipform can improve efficiency, it is costly. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide an auxiliary construction device for slope concrete pouring, which can provide a support platform for slope concrete pouring construction. It has a simple structure, is easy to install, and can greatly improve the efficiency of slope concrete pouring and reduce costs.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: An auxiliary construction device for slope concrete pouring includes a working platform and an assemblable ladder; The working platform includes a support platform, with mounting seats arranged on both the left and right sides at the top of the support platform. One end of the connecting rod is connected to the mounting seat, and the other end is hung in the perforation of the steel template. The modular ladder includes multiple sets of ladder units. Each set of ladder units includes a ladder body with legs fixed at the bottom and hanging rings and safety hooks fixed at both ends. Adjacent ladder units are connected by hanging rings and safety hooks.

[0006] Each side of the support platform is provided with two sets of mounting seats, and each set of mounting seats has mounting holes at the front and rear of the upper end; one set of connecting rods is inserted into the mounting hole at the front end of the mounting seat and then locked with a nut; the other set of connecting rods is inserted into the mounting hole at the rear end of the mounting seat and then locked with a nut.

[0007] The bottom of the support platform is fixed with reinforcing ribs along the longitudinal or transverse direction.

[0008] A pad is fixed to the lower end of the outrigger.

[0009] The top of the modular ladder is equipped with a ladder connector, which includes a telescopic rod with a hook at the top. The hook is hung on a hole in the steel template. The bottom of the telescopic rod is connected to the hanging ring of the modular ladder via a safety hook.

[0010] The telescopic rod includes a threaded rod and a threaded sleeve, and the threaded rod and the threaded sleeve are connected by threads.

[0011] The modular ladder is made of aluminum alloy.

[0012] This utility model provides an auxiliary construction device for slope concrete pouring, which has the following technical effects: 1) By using standardized steel formwork, each newly poured and solidified slope layer serves as a support for the modular ladders and work platforms throughout the process. The remaining steel formwork acts as a reliable connector, ensuring the stability of the construction platform. Workers can then perform various tasks on the next level. The modular ladders facilitate the access to materials, and the work platforms facilitate pre-construction preparations and subsequent pouring work.

[0013] 2) This device does not require a full-span scaffolding platform, which helps improve construction efficiency and shorten the construction period; at the same time, it reduces rental costs compared to large lifting platforms.

[0014] 3) By using a quick-assembly ladder, it can be continuously assembled upwards as the slope is poured, making installation convenient; the bottom of the ladder contacts the slope surface and is supported by the slope surface, and the top of the ladder is connected to the steel formwork to prevent the ladder from tipping over or shifting, thus ensuring stability.

[0015] 4) A simple working platform consisting of a support platform, mounting base, and connecting rods is used. This working platform is hung on the steel formwork, which makes it quick and easy to remove and install, thus improving efficiency. Attached Figure Description

[0026] like Figure 1 , Figure 3 As shown, an auxiliary construction device for slope concrete pouring includes a working platform 1 and an assemblable ladder 2.

[0027] like Figure 2 , Figure 4 As shown, the working platform 1 consists of multiple sets, each set including a support platform 1.1. Mounting seats 1.2 are arranged on both the left and right sides of the upper end of the support platform 1.1, with the mounting seats 1.2 arranged along the width direction of the support platform 1.1. Mounting holes 1.3 are opened at the front and rear of the upper end of the mounting seats 1.2. One end of the connecting rod 1.4 is hung in the through hole of the back reinforcement plate of the steel formwork 3, and the other end of the connecting rod 1.4 passes through the front or rear mounting hole 1.3 and is locked with a nut 1.5. Here, the steel formwork 3 refers to the upper part of the steel formwork that has been poured and solidified but not removed. After installation, one end of the support platform 1.1 rests on the concrete layer 4 that has been poured, solidified, and the steel formwork removed, with the outer end of the support platform 1.1 suspended in the air.

[0028] like Figure 2 As shown, preferably, the support platform 1.1 has two sets of mounting seats 1.2 on both the left and right sides. Each set of mounting seats 1.2 corresponds to a set of connecting rods 1.4. Of the two sets of connecting rods 1.4, one set is inserted into the front mounting hole 1.3 and locked, while the other set is inserted into the rear mounting hole 1.3 and locked. In this way, the support platform 1.1 is subjected to tensile force from both the front and rear, ensuring stability after installation.

[0029] like Figure 4 As shown, preferably, the bottom end of the support platform 1.1 is fixed with a reinforcing rib 1.6 along the longitudinal or transverse direction, and the reinforcing rib 1.6 ensures the support strength of the support platform 1.1.

[0030] like Figure 1 , Figure 7 As shown, there is at least one set of modular ladder 2. Modular ladder 2 is made of aluminum alloy, which is lightweight, high-strength, and easy to carry.

[0031] like Figure 5 As shown, the modular ladder 2 includes multiple ladder units 2.1, which are spliced ​​end-to-end. Each ladder unit 2.1 includes a main body with legs 2.2 fixed to its lower end at all four sides. The lower ends of the legs 2.2 rest on a pre-cast concrete slope, providing support for the modular ladder 2. A hanging ring 2.3 is fixed to one end of the main body, and a safety hook 2.4 is fixed to the other end. Adjacent ladder units 2.1 can be spliced ​​end-to-end using these hanging rings 2.3 and safety hooks 2.4. This connection ensures a secure connection and allows for easy adjustment of the angle between adjacent ladder units 2.1, facilitating adjustments based on actual needs.

[0032] Preferably, a pad 2.5 is fixed to the lower end of the outrigger 2.2. The pad 2.5 increases the area and improves the stability of the support.

[0033] like Figure 6 As shown, preferably, a ladder connector 2.6 is arranged at the uppermost end of the modular ladder 2. The ladder connector 2.6 includes a telescopic rod with a hook at the upper end, which can be hooked into the through hole of the back reinforcement plate of the steel formwork 3. A safety hook 2.4 is provided at the lower end of the telescopic rod. The safety hook 2.4 is hooked to the hanging ring 2.3 of the uppermost ladder unit 2.1 of the modular ladder 2. In this way, the upper end of the modular ladder 2 can be connected to the fixed steel formwork 3, ensuring the stability of the modular ladder 2.

[0034] The telescopic rod of the ladder connector 2.6 can be connected by a threaded rod and a threaded sleeve to achieve telescopic movement. Preferably, the telescopic rod can be a turnbuckle. By setting the telescopic rod, it is easy to adjust to the normal length and easy to hang it with the steel formwork 3.

[0035] Slope concrete pouring is carried out from bottom to top.

[0036] Preferably, a foldable guardrail can be installed on the support platform 1.1 to improve safety.

[0037] Working principle and process: Step 1: Initially, a scaffold is erected at the bottom of the slope to carry out the reinforcement binding, formwork erection and pouring of the first section (about 1-2 meters high); the formwork installation and foundation pouring are completed.

[0038] Step 2: Once the concrete strength of the first section at the bottom of the slope reaches the specified requirements (usually enough to ensure the stability of the structure itself), remove some of the steel formwork in the middle and lower positions, and retain the two rows of steel formwork at the top. The retained steel formwork serves as the connection foundation for the working platform 1 and the assembled ladder 2, and also as the installation foundation for the steel formwork used for the next section of concrete pouring.

[0039] Step 3: Assemble the modular ladder 2 according to the distance from the bottom of the poured concrete slope to the retained steel formwork. Place the modular ladder 2 at a suitable position on the poured concrete slope so that workers can climb to the retained steel formwork using the modular ladder 2. Multiple sets of modular ladder 2 can be arranged at intervals. Workers use the modular ladder 2 to carry the work platform 1 to the retained steel formwork and hang it on the retained steel formwork via the connecting rod 1.4. The specific configuration is as follows. Figure 8 As shown in ①.

[0040] Step Four: Workers can then perform the following tasks on work platform 1: binding of reinforcing bars for the next section of concrete pouring, erection of steel formwork (the main tasks include: standing on work platform 1 and using ropes to pull the steel formwork up from the bottom of the slope, which also serves as a path; after reaching the area where formwork needs to be laid, the worker stops, then climbs up the slope to install the formwork), and concrete pouring (manually standing on work platform 1, holding the grouting pipe for pouring). Specific details are as follows: Figure 8 As shown in ②.

[0041] Step 5: After the second section of concrete reaches the specified strength, retain the top two rows of steel formwork 3 and the bottom row of steel formwork 3. Remove the middle rows of steel formwork 3 and the steel formwork at the installation point of the modular ladder 2. Remove the ladder connector 2.6 and continue assembling the ladder unit 2.1 upwards until the top two rows of steel formwork. Connect both ends of the ladder connector 2.6 to the upper end of the modular ladder 2 and the steel formwork respectively to keep the modular ladder 2 stable. The specific state is as follows: Figure 8 As shown in ③.

[0042] Step Six: Then, remove the work platform 1 from the original steel formwork, move it up using the modular ladder 2, and re-hang it on the new steel formwork. The specific details are as follows: Figure 9 As shown in ④. Remove the remaining steel formwork 3 at the bottom, as shown in the specific state. Figure 9 As shown in section ⑤; prepare for the next stage of concrete pouring.

[0043] Step Six: Continue construction upwards in a cyclical manner until the designed slope height is reached.
