Abstract
The utility model relates to a waterproof device for splicing an external wall of an assembly type building, which consists of a first precast concrete wall body, a waterproof strip, a pier seat, a second precast concrete wall body, a sealant and a back cushion foam strip, wherein a waterproof strip, the sealant and a back cushion foam strip waterproof material are arranged between the pier seat at the bottom of the first precast concrete wall body and the pier seat at the top end face of the second precast concrete wall body, and the inner side of the top end face of the second precast concrete wall body is higher than the outer side of the second precast concrete wall body; the shape of the end face of the bottom of the first precast concrete wall body is matched with the shape of the end face of the top of the second precast concrete wall body, and the sealant (the part contacting with the outdoor) has excellent weather resistance and cannot cause secondary pollution in long-term use; the rubber strip is a third material of the wall body, and a post-sticking method is adopted to prevent water from entering a room in windy weather; the waterproof strips and the sealant (the contact part with the indoor) have good flexibility and bonding force with a concrete interface, and prevent the wall from generating cracks and causing water leakage.
Description
Technical Field
The utility model relates to a building field, in particular to watertight fittings of assembled building outer wall concatenation.
Background
With the increasing population of China and the rapid development of the urbanization level, the demand of urban residences is increasing. While the residential building market is greatly developed, the requirements of people on the quantity and quality of residences cannot be met due to the restriction of the design and construction technology of the existing residences.
For the traditional residential construction method, the construction of the standard floor of the traditional residential building needs 5 days/floor, and the time from the start of work to the delivery of one residential building in a community is generally one or two years due to the decoration in the later period. Moreover, the traditional residential structure is influenced by the level of field constructors, construction environment and construction noise, and in addition, the construction quality is not easy to control and other quality common defects. In addition, it results in waste of materials, tools, etc., which is far less effective than those of the prefabricated building in the above-described aspects.
For the assembly type building, in the construction process, firstly, the adopted components are all produced in a factory, so that the assembly type building has the advantages of easily controlled construction quality, material saving, reduced building garbage generated in a construction site, environmental protection and the like; and secondly, the adopted components are standard products, and can be directly installed when being transported to the site, so that the site construction strength is reduced, the masonry and plastering procedures can be omitted, and the construction time can be greatly saved.
However, one problem faced by the current fabricated building is that the joints of the walls are prone to water seepage after the external sealant cracks, i.e., water drops may permeate into the room along the gaps between the precast concrete walls, so that the exterior walls lose the properties of freeze-thaw resistance, high and low temperature resistance, wind load resistance and the like, and therefore a waterproof device capable of solving the water seepage problem faced by the exterior walls of the fabricated building is urgently needed.
SUMMERY OF THE UTILITY MODEL
In order to solve the assembly type structure outer wall infiltration problem, an object of the utility model is to provide a watertight fittings of assembly type structure outer wall concatenation can improve the water-proof effects of assembly type structure outer wall effectively.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
the utility model provides a watertight fittings of assembled building outer wall concatenation, includes first precast concrete wall body, waterproof strip, pier base, second precast concrete wall body, sealed glue, back of the body fills up the foam strip, be equipped with waterproof strip, sealed glue, back of the body fills up foam strip waterproof material between first precast concrete wall body's bottom pier base and second precast concrete wall body's the top end face pier base, the inside portion of second precast concrete wall body's top end face is higher than the outside portion, just the shape of first precast concrete wall body's bottom terminal surface and the shape phase-match of second precast concrete wall body's top end face.
Preferably, the waterproof strip is made of a rubber material.
Preferably, the sealant is cross-shaped.
Preferably, the back pad foam strip shape is hexagonal.
The utility model has the advantages that:
(1) the sealant in the outdoor contact part has excellent weather resistance, and can not cause secondary pollution in long-term use;
(2) the rubber strip is the third material of the wall body, and the adopted method is a post-sticking method (namely, a groove needs to be reserved on the component when the component is produced, and a rubber strip needs to be stuck on the component when the component is installed), so that water is prevented from entering a room in strong wind weather;
(3) the waterproof material (namely waterproof strip and sealant) used at the indoor contact part has good flexibility and bonding force with a concrete interface, and prevents the wall from generating cracks and causing water leakage.
Drawings
Fig. 1 is the utility model relates to a watertight fittings's of assembly type structure outer wall concatenation schematic diagram.
In the figure: 1 first precast concrete wall body, 2 rubber strips, 3 pier bases, 4 second precast concrete wall bodies, 5 sealants and 6 back cushion foam strips.
Detailed Description
The utility model is described in detail with the following figures:
the utility model provides a watertight fittings of assembled building outer wall concatenation, includes first precast concrete wall 1, rubber strip 2, pier base 3, second precast concrete wall 4, sealed glue 5, back of the body pad foam strip 6, be equipped with waterproof strip 2, sealed glue 5, back of the body pad foam strip 6 waterproof material between first precast concrete wall 1's bottom pier base and second precast concrete wall 2's the top end face pier base 3, the inside portion of second precast concrete wall 4's top end face is higher than the outside portion, just the shape of first precast concrete wall 1's bottom end face matches with the shape of second precast concrete wall 4's top end face.
In the using process, the part which is in contact with the external environment is influenced by natural environments such as sunlight and the like for a long time, the used sealant 5 has excellent weather resistance, and meanwhile, the sealant 5 cannot cause secondary pollution when being used for a long time, so that the overall effect of the exterior decoration of the building is influenced; the rubber strip 2 is a third material of the wall body, and the adopted method is a post-sticking method (namely, when the member is produced, a groove needs to be reserved on the member, and when the member is installed, a rubber strip needs to be stuck on the member), so that water is prevented from entering a room in strong wind weather; the environment is relatively stable at the contact position with the indoor, but the waterproof material used as the last waterproof layer (namely the waterproof strip 2 and the sealant 5) has good flexibility and bonding force with a concrete interface, and water leakage caused by cracks generated on a wall body is avoided.
Of course, the above description is not intended to limit the present invention, and the present invention is not limited to the above examples, and the changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present invention should also belong to the protection scope of the present invention.
