Description

Technical Field

[0001] The invention relates to the technical field of assembled buildings, in particular to a core hole steam curing device for concrete lightweight partition board strips. Background Art

[0002] The country is currently promoting prefabricated buildings, one of which is lightweight wall panels. There are many types of lightweight wall panels with uneven quality. According to the maintenance conditions, they are divided into natural curing and steam curing. Naturally cured wall panels have low strength, poor appearance, and are prone to cracking; therefore, steam curing is particularly important.

[0003] At present, there are two main production processes for lightweight wallboards, namely Figure 6 and Figure 7 The first type is Figure 6 As shown in the figure, the first process is more commonly used in the south. The disadvantage is that the demoulding time is too long, occupying the mold trolley for more than 20 hours, only one production per day, and the concrete strength is slowly improved, and the delivery time is as long as 15 days; the second process is as shown in the figure. Figure 7 As shown, the second process is to move the mold trolley to the steam room and heat the mold trolley and the concrete wall panel as a whole in order to shorten the demolding time. The disadvantages of this method are that it is time-consuming and labor-intensive to move the mold trolley, the steam has a great influence on the deformation of the mold trolley, shortening the service life of the mold trolley, and the wall panel is wrapped by a thicker mold steel plate, which heats slowly and no water vapor enters, so the actual use efficiency is not high.

[0004] Therefore, we proposed a core hole steam curing device for lightweight concrete partition panels to solve the problems of slow production time, poor wall panel structure quality and easy cracking of lightweight concrete wall panels. Summary of the invention

[0005] The invention provides a core hole steam curing device for concrete lightweight partition board strips, which solves the problems of slow board production time, poor wall board structure quality and easy cracking of concrete lightweight wall boards.

[0006] The present invention provides the following technical solution: a steam curing device for core holes of concrete lightweight partition wall panels, comprising a mold trolley body, a curing base is fixedly installed on the top of the mold trolley body, a bottom support seat is fixedly connected to the bottom of the mold trolley body, a mold platform protection plate is fixedly connected to the top of the curing base, a plurality of partitions are fixedly connected to the inside of the mold platform protection plate, and a concrete lightweight wall panel is arranged between the adjacent partitions, wall panel ends are formed on both sides of the concrete lightweight wall panel, a core hole is opened inside the wall panel end, a core through tube is sleeved inside the core hole, and a steam curing device is connected between the core through tubes in the same horizontal direction;

[0007] The steam maintenance device includes a reducer, which is sleeved with the core-penetrating pipe, and adjacent reducers are connected through a ventilation connecting pipe. The ventilation connecting pipe includes an adapter, an S tee and a reducing tee. The adapter is located at the top of the ventilation connecting pipe, and the adapter is connected to the top reducer. The S tee is located in the middle, and the bottom end of the adapter is connected to the S tee. There are several S tees in the middle of the ventilation connecting pipe, and adjacent S tees are connected to each other. The reducing tee is located at the bottom of the ventilation connecting pipe, and the top of the reducing tee is connected to the S tee at the bottom, and the right side of the reducing tee is fixedly connected to an air intake pipe.

[0008] Preferably, an outer side of the steam curing device is connected to an outer protective cover, and an air inlet pipe passes through the outer protective cover and extends to the outer side of the outer protective cover.

[0009] Preferably, the other end of the core hole away from the reducer is connected to a silicone seal, and the silicone seal and the opening of the core hole are in a sealed state, and an exhaust circular hole is opened on the other side of the silicone seal, and the diameter of the exhaust circular hole is 5mm.

[0010] Preferably, the steam curing device is fixed to one side of the mold trolley body through a clamp and a connecting page.

[0011] Preferably, the steam curing device is externally connected to a steam generator, and the output end of the steam generator is connected to the air inlet pipe through a cloth-reinforced rubber tube.

[0012] Preferably, the two ends of the reducer are divided into a large end and a small end, the large end of the reducer is sealed and connected to the core tube through a silicone sealing ring, and the small end of the reducer is connected to an adapter, an S tee joint or a reducer tee joint.

[0013] A curing process of a core hole steam curing device for a concrete lightweight partition wall slat includes the following steps:

[0014] Step 1: Mold trolley preparation

[0015] Prepare corresponding mold trolleys for the production of lightweight concrete wall panels;

[0016] Step 2: Mixing the Concrete

[0017] Prepare the raw materials and pour the corresponding raw materials into the concrete mixer for full mixing;

[0018] Step 3: Pour the mold into the trolley

[0019] Pour the mixed concrete into the mold truck to form the concrete lightweight wall panels;

[0020] Step 4: The core hole steam curing device heats the core tube

[0021] After pouring is completed, the steam curing device is turned on to heat the core tube, which is located in the poured concrete wall panel and in contact with the concrete wall panel, thereby increasing the heating area of ​​the concrete wall and effectively shortening the setting time of the concrete wall;

[0022] Step 5: Let it sit

[0023] Allow to stand for 10 hours to allow the concrete to solidify effectively in the formwork vehicle to form a corresponding lightweight concrete wall structure;

[0024] Step 6: Pull out the core tube

[0025] When the concrete lightweight wall structure solidifies for a certain period of time, its strength is large enough to pull out the corresponding core tube structure;

[0026] Step 7: The core hole air curing device steam-presses the core hole of the wall panel

[0027] After the core tube is pulled out, a core hole is formed in the lightweight concrete wall. The core hole is directly autoclaved and cured by a steam curing device. The autoclaving time is 2 hours. The concrete wallboard has both temperature and humidity, and its strength increases rapidly.

[0028] Step 8: The mold trolley takes out the board

[0029] The concrete lightweight wall structure after the mold trolley unloads the plate and completes the curing;

[0030] Step 9: Steam Curing

[0031] The wall structure after curing is uniformly transported to the steam curing warehouse for another curing operation;

[0032] Step 10: Demolding and leaving the factory

[0033] After completing 36 hours of curing in the steam curing chamber, the concrete can be taken out of the chamber, completing the production and preparation of the corresponding lightweight concrete wall structure.

[0034] The present invention has the following beneficial effects:

[0035] The core hole steam curing device for concrete lightweight partition board strips inputs steam into the core tube immediately after pouring concrete to heat the core tube, thereby increasing the contact area between the core tube and the wallboard. After heating, the setting time of the concrete is greatly shortened. After reaching a certain strength, the core tube is pulled out. At this time, the steam directly performs autoclave curing on the wallboard. The concrete wallboard has both temperature and humidity, and its strength increases rapidly. The board can be produced in three hours.

[0036] By comparison, it can be seen that compared with the process technology that also uses steam curing, after installing the core hole steam curing device, the demoulding time can be shortened by half, which greatly increases the production efficiency. At the same time, the wall panels that are steam-cured for the first time have more guaranteed quality and rapid strength growth, which makes a great contribution to preventing cracks. The factory delivery time is also shortened by one third, which greatly improves the product quality and production rate. BRIEF DESCRIPTION OF THE DRAWINGS
