Description

Technical Field

[0001] The utility model relates to the technical field of post - casting belt advanced water - stop construction, in particular to a device for controlling the verticality of extruded polystyrene boards in the post - casting belt. Background Technique

[0002] The post - casting belt is a concrete belt left at the corresponding positions of the foundation slab, wall, and beam during building construction to prevent harmful cracks that may occur in the reinforced concrete structure due to uneven self - shrinkage or settlement. Before the post - casting belt is closed, it is inevitable that some sundries will fall in, and it is very difficult to clean them up. Rainwater and construction water are very easy to penetrate into the basement, interfering with normal construction operations. And due to the setting of the post - casting belt on the exterior wall, it interferes with the waterproofing of the exterior wall and the smooth construction of the outdoor backfill soil, causing inconvenience to various management orders at the construction site. In the advanced water - stop construction technology for the post - casting belt of the exterior wall of the basement, prefabricated ones are usually used to ensure the successful implementation of wall waterproofing and backfill soil construction before the post - casting belt is closed, creating more convenient conditions for later construction.

[0003] At present, in the advanced water - stop construction, there are problems that the extruded polystyrene board is easy to shift and be damaged, and the thickness of the steel bar protection layer on its left and right sides cannot be controlled. To solve this problem, the utility model proposes a device for controlling the verticality of the extruded polystyrene board in the post - casting belt. Summary of the Invention

[0004] The purpose of the utility model is to solve the problems raised in the background technique, and provide a device for controlling the verticality of the extruded polystyrene board in the post - casting belt.

[0005] The technical solution of the utility model to achieve the above - mentioned purpose is as follows:

[0006] A device for controlling the verticality of the extruded polystyrene board in the post - casting belt includes an upper baffle, a limiting plate, a connection hole, a positioning mechanism, a distance - determining plate, and a side plate. Both ends of the upper baffle are slidably connected to a limiting plate respectively, and a number of uniformly spaced connection holes are opened on the upper baffle. There are two sets of positioning mechanisms, which are symmetrically arranged on the two limiting plates respectively. The positioning mechanism includes a clamping block, a spring, and a push plate. The clamping block is slidably connected to the limiting plate. The spring is located inside the limiting plate, one end of which is fixedly connected to the limiting plate, and the other end of the spring is fixedly connected to the clamping block. The limiting plate is slidably connected to the push plate. Each limiting plate is fixedly connected to a distance - determining plate respectively. On the upper and lower sides of each distance - determining plate, a side plate is fixedly connected respectively.

[0007] Preferably, two guiding blocks are provided on the upper baffle, and the two guiding blocks are fixedly connected to both sides of the upper baffle respectively. A guiding groove is provided on the limiting plate, which is opened inside the limiting plate, and the guiding block is slidably connected to the guiding groove.

[0008] Preferably, the distance between adjacent connection holes on the upper baffle is 0.5 cm.

[0009] Preferably, a scale is provided on the upper baffle, and the scale is fixedly connected to the upper baffle.

[0010] Preferably, fixing holes are provided on the side plates, and the fixing holes are opened on the side plates and are close to the distance-determining plates in position.

[0011] The utility model provides a device for controlling the perpendicularity of extruded polystyrene boards in post-cast strips, and has the following beneficial effects:

[0012] Through its structural design, after the extruded polystyrene board is installed, the upper baffle and the limiting plates are installed above the extruded polystyrene board. Then, the distance between the two limiting plates is adjusted according to the thickness specification of the extruded polystyrene board. At this time, the spring in the positioning mechanism drives the clamping block to be located within the limiting plate, and the two limiting plates can be slid towards the middle, so that the two limiting plates slide along the upper baffle to closely adhere to the extruded polystyrene board. At this time, the push plate is pushed, and the push plate is pushed towards the clamping block. The movement of the push plate drives the clamping block to move towards the upper baffle. When the push plate moves to the end, the clamping block completely falls into the connection hole, fixing the position of the limiting plate. After the position of the limiting plate is fixed, the side plates are connected to the longitudinal steel bars on both sides, connecting and fixing the utility model with the advanced water-stop structure. The size of the distance-determining plate is determined by the required protective layer thickness of the steel bars. Compared with the prior art, the utility model limits the extruded polystyrene board through the upper baffle and the limiting plates, ensuring the perpendicularity of the extruded polystyrene board, preventing the extruded polystyrene board from floating or deviating, and at the same time protecting the extruded polystyrene board from external force damage. The distance-determining plate ensures that the distance between the longitudinal steel bars and the extruded polystyrene board meets the requirements of the steel bar protective layer thickness.

[0021] Please refer to Figures 1-3 , the present utility model provides a device for controlling the perpendicularity of extruded polystyrene boards in post-cast strips, including an upper baffle 1, a limiting plate 2, a connection hole 3, a positioning mechanism, a distance-fixed plate 7, and a side plate 8. Both ends of the upper baffle 1 are slidably connected to a limiting plate 2 respectively. A plurality of connection holes 3 are evenly spaced and arranged on the upper baffle 1 and are used in cooperation with the positioning structure. There are two sets of positioning mechanisms and they are symmetrically arranged on the tops of the two limiting plates 2. The positioning mechanism includes a clamping block 4, a spring 5, and a push plate 6. The clamping block 4 is slidably connected to the limiting plate 2 up and down. The clamping block 4 is used in cooperation with the connection hole 3. The spring 5 is located inside the limiting plate 2 and one end of the spring 5 is fixedly connected to the limiting plate 2, and the other end of the spring 5 is fixedly connected to the clamping block 4. The limiting plate 2 is slidably connected to the push plate 6. The push plate 6 is located on one side of the clamping block 4. The push plate 6 can push the clamping block 4 downward by sliding until it is pushed into the connection hole 3. The bottom of each limiting plate 2 is fixedly connected to a distance-fixed plate 7 respectively. The upper and lower sides of each distance-fixed plate 7 are fixedly connected to a side plate 8 respectively.

[0022] In the present utility model, two guiding blocks 9 are provided on the upper baffle 1, and the two guiding blocks 9 are respectively fixedly connected to both sides of the upper baffle 1. A guiding groove 10 is provided on the limiting plate 2, and the guiding groove 10 is formed inside the limiting plate 2. The guiding block 9 is slidably connected to the guiding groove 10; through the guiding block 9 on the upper baffle 1 and the guiding groove 10 on the limiting plate 2, the upper baffle 1 can slide more stably inside the limiting plate 2.

[0023] In the present utility model, the distance between adjacent connecting holes 3 on the upper baffle 1 is 0.5 cm; through the connecting holes 3 with a mutual distance of 0.5 cm, the moving distance of the limiting plate 2 corresponds to the conventional size of the extruded polystyrene board.

[0024] In the present utility model, a scale 11 is provided on the upper baffle 1, and the scale 11 is fixedly connected to the upper baffle 1; through the scale 11 on the upper baffle 1, the operator can more accurately determine the thickness of the extruded polystyrene board, so as to understand the fitting degree between the limiting plate 2 and the extruded polystyrene board.

[0025] In the present utility model, fixing holes 12 are provided on the side plate 8, and the fixing holes 12 are formed on the side plate 8 and are close to the distance-determining plate 7 in position; through the fixing holes 12 on the side plate 8, it is convenient for the operator to bind and connect the present utility model with the longitudinal steel bars on both sides.

[0026] In this implementation scheme: when carrying out the advanced water stop construction for the post-cast strip, first, a cushion layer is poured at the bottom of the post-cast strip, then waterproof coiled materials and water stop belts are laid above the cushion layer. After the waterproof coiled materials and water stop belts are laid well, the steel bars are tied according to the regulations. After the steel bars are tied well, the extruded polystyrene board is installed according to the construction requirements. After the extruded polystyrene board is installed, the upper baffle 1 and the limiting plate 2 are installed above the extruded polystyrene board. Then, the distance between the two limiting plates 2 is adjusted according to the thickness specification of the extruded polystyrene board. At this time, the spring 5 drives the clamping block 4 to be inside the limiting plate 2, and the two limiting plates 2 can be slid towards the middle, so that the two limiting plates 2 slide along the upper baffle 1 to be close to the extruded polystyrene board. Through the guiding block 9 on the upper baffle 1 and the guiding groove 10 on the limiting plate 2, the upper baffle 1 can slide more stably inside the limiting plate 2. At this time, the push plate 6 is pushed, and the push plate 6 is pushed towards the clamping block 4. The movement of the push plate 6 drives the clamping block 4 to move towards the upper baffle 1. When the push plate 6 moves to the most end, the clamping block 4 completely falls into the connecting hole 3, fixing the position of the limiting plate 2. Through the scale 11 on the upper baffle 1, the operator can more accurately determine the thickness of the extruded polystyrene board, so as to understand the fitting degree between the limiting plate 2 and the extruded polystyrene board. After the position of the limiting plate 2 is fixed, the side plate 8 is connected to the longitudinal steel bars on both sides, so that the present utility model is connected and fixed to the advanced water stop structure. Through the fixing holes 12 on the side plate 8, it is convenient for the operator to bind and connect the present utility model with the longitudinal steel bars on both sides. The size of the distance-determining plate 7 is determined by the required protective layer thickness of the steel bars.
