Description

Technical Field

[0001] The utility model relates to the technical field of construction equipment, in particular to a waterproof construction equipment for the exterior wall post-cast strip. Background Technique

[0002] The post-cast strip is a temporary construction joint left at the corresponding positions of the foundation slab, wall, and beam in accordance with design or construction regulations in order to prevent harmful cracks that may occur due to uneven temperature and shrinkage in the cast-in-place concrete structure. The structure is temporarily divided into several parts. After the internal shrinkage of the components, the concrete of the construction joint is poured after a certain period of time to connect the structure into a whole. In the construction of building projects, the construction of the basement of the building structure plays a very important role in the project building. On the one hand, it is conducive to the transfer of building loads, and on the other hand, it can also bear extremely strong bearing capacity, which is conducive to ensuring the stability of the construction. Therefore, the structure of the post-cast strip of the basement top floor slab is very important.

[0003] In order to increase the waterproof performance, a waterproof layer is provided on the outside after the concrete is backfilled for the post-cast strip. The waterproof layer uses SBS waterproof coiled material, which is manually laid on the post-cast strip. The steps of manual laying are relatively cumbersome. It is necessary to gradually heat the waterproof coiled material and then bond it to the post-cast strip. The work efficiency is relatively low, and the work burden of workers is relatively high, which is not convenient for use. Content of the Utility Model

[0004] The purpose of the utility model is to solve the problem that the steps of manual laying in the prior art are relatively cumbersome, it is necessary to gradually heat the waterproof coiled material and then bond it to the post-cast strip, and the work efficiency is relatively low, and a waterproof construction equipment for the exterior wall post-cast strip is proposed.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0006] A waterproof construction equipment for the exterior wall post-cast strip, including a chassis, two support rods are fixed at the top of the chassis, U-shaped grooves are opened in both of the support rods, a first rotating shaft is arranged in the U-shaped groove, and a waterproof coiled material for waterproof construction is arranged on the surface of the first rotating shaft;

[0007] A flattening wheel, a fixed block is fixed at the top of the chassis, the flattening wheel is arranged below the fixed block for flattening the waterproof coiled material attached to the post-cast strip, and a set of elastic extrusion components for driving the flattening wheel to extrude and paste the waterproof coiled material are arranged between the fixed block and the flattening wheel;

[0008] Heating part, the heating part includes a horizontal plate fixed inside the chassis. A third groove is formed in the horizontal plate. A fixed frame is rotatably disposed in the third groove. A blowtorch for flame heating is fixed inside the fixed frame. The blowtorch faces the unfolding surface of the waterproof coiled material. A fixing frame is fixed inside the chassis. A gas tank communicated with the blowtorch is fixed inside the fixing frame. The gas tank is used to accommodate the fuel of the blowtorch;

[0009] Swinging assembly, the swinging assembly is disposed inside the horizontal plate and is used to drive the blowtorch to swing for heating;

[0010] Moving wheels are rotatably disposed at the four corners of the bottom end of the chassis.

[0011] In a possible design, the elastic extrusion assembly includes a first groove formed in the fixed block. Two limiting rods are fixed inside the first groove. The same inverted U-shaped frame slides on the surfaces of the two limiting rods. The flattening wheel rotates between the inverted U-shaped frames. Two springs are fixed at the top end of the inverted U-shaped frame. The side ends of the two springs are fixed inside the first groove. The two springs are respectively sleeved on the surfaces of the two limiting rods.

[0012] In a possible design, U-shaped limiting blocks are fixed inside the two U-shaped grooves. Two limiting grooves are formed on the surface of the first rotating shaft. The two limiting grooves respectively match the two U-shaped limiting blocks.

[0013] In a possible design, the swinging assembly includes a second groove formed in the horizontal plate. A half-tooth gear slides inside the second groove. A half-tooth ring that intermittently meshes with the half-tooth gear rotates inside the second groove. A driving rack is fixed at the side end of the half-tooth gear. A second rotating shaft rotates inside the second groove. A first gear meshing with the driving rack is fixed on the surface of the second rotating shaft. A driving motor is fixed at the side end of the horizontal plate. The driving motor is connected to the half-tooth ring through a coupling. The second rotating shaft extends outwards and penetrates into the third groove and is fixedly connected to the fixed frame. A fixed frame is fixed at the side end of the second rotating shaft. The blowtorch is fixed inside the fixed frame.

[0014] In a possible design, two placing rods are fixed at the top end of the chassis. A push handle is fixed between the two placing rods.

[0015] In a possible design, an anti-slip sleeve is sleeved on the surface of the push handle.

[0016] In this application, when in use, the waterproof coiled material is unrolled. After the side end of the unrolled waterproof coiled material is manually heated and pasted and fixed to the post-cast strip, the unrolled part of the waterproof coiled material is placed under the flattening wheel and moved by the pushing device. Subsequently, there is no need for manual heating anymore. By starting the blowtorch, the extended part of the waterproof coiled material is heated. By starting the drive motor to drive the semi-toothed ring to rotate, the rotation of the semi-toothed ring drives the semi-toothed gear to move in a linear reciprocating motion. The semi-toothed gear drives the drive rack to move in a linear reciprocating motion in the second groove. The drive rack drives the first gear to swing reciprocally. When the first gear swings reciprocally, it drives the second rotating shaft to rotate reciprocally. The second rotating shaft drives the fixed frame to rotate. The rotation of the fixed frame drives the blowtorch to swing reciprocally. The swinging of the blowtorch can cover the entire transverse range of the waterproof coiled material, enabling it to be evenly heated, which is more conducive to the connection between the waterproof coiled material and the post-cast strip.

[0017] Since the heated waterproof coiled material is located under the flattening wheel, when passing through the flattening wheel, it is pressed downward by the elasticity of the spring. The spring pushes the flattening wheel to squeeze and move downward, and the flattening wheel tightly connects the heated waterproof coiled material and the post-cast strip.

[0018] In the present utility model, for the described exterior wall post-cast strip waterproof construction equipment, through the elastic extrusion assembly, the effect of quickly rolling and flattening the laid waterproof coiled material can be achieved.

[0019] In the present utility model, for the described exterior wall post-cast strip waterproof construction equipment, through the swinging assembly, the effect of driving the blowtorch to swing horizontally can be achieved, enabling the blowtorch to heat the entire cross-section of the waterproof coiled material, which is convenient for the connection between the waterproof coiled material and the post-cast strip.

[0020] In the present utility model, in this technical solution, through the elastic extrusion assembly, the effect of quickly rolling and flattening the laid waterproof coiled material can be achieved. Through the swinging assembly, the effect of driving the blowtorch to swing horizontally can be achieved, enabling the blowtorch to heat the entire cross-section of the waterproof coiled material, which is convenient for the connection between the waterproof coiled material and the post-cast strip. It can effectively replace manual laying of the waterproof coiled material, effectively improve work efficiency, reduce the work burden of workers, and is convenient for use.
